Description

CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese Patent Application No. 202010273616.1 with a filing date of Apr. 9, 2020. The content of the aforementioned application, including any intervening amendments thereto, are incorporated herein by reference.

TECHNICAL FIELD

The present invention relates to a curtain rod mounting component, in particular to a punching-free electric mounting unit and a curtain rod with the mounting unit.

BACKGROUND

A hanging curtain used for sun shading, decoration and the like usually comprises a curtain fabric and a rod. Hanging curtains such as window curtains, door curtains, shower curtains and the like generally adopt customized production. To be specific, the dimensions of the location where a hanging curtain is planned to be installed are measured, and then the hanging curtain is produced in a customized manner according to the measured specific dimensions including the length of a customized rod, the width of a curtain fabric and so on. In this process, it is easy to cause inaccuracy of measured dimensions due to various reasons, particularly, the length of the rod does not fit with the width of a to-be-installed location so that the hanging curtain is unsuccessfully installed, or the hanging curtain is scrapped because of overlarge gaps, greatly wasting social resources. In view of the above problem, there provides a technical solution of adjusting the length of the rod, that is, an end portion of the rod is in threaded connection with the main body of the rod, and then the end portion of the rod is rotated to be away from or close to the main body of the rod, thereby adjusting the length of the whole rod to adapt to the dimensions of the to-be-installed location. It may take great effort since the existing adjustment is achieved by artificially rotating the end portion of the rod. In particular, when the rod is installed at a higher place, a person needs to support the rod for a long time, which is time-wasting and labor-consuming, and inconvenient to mount and adjust.

SUMMARY

One objective of the present disclosure is to overcome the shortcomings of the prior arts by providing a punching-free electric mounting unit which is convenient to mount and adjust.

The technical solution of the present invention provides a punching-free electric mounting unit, comprising a housing, and a motor is arranged within the housing. The output end of the motor is provided with a decelerating mechanism, a connecting block and a pushing block in turn. The pushing block is capable of moving relative to the connecting block. The output speed of the motor is decelerated by the decelerating mechanism and then transferred to the connecting block to drive the connecting block to act, and then the connecting block drives the pushing block to move. The fine tuning of the length of the curtain rod is realized through outward movement of the pushing block, so the length of the curtain rod fits with the dimensions of the to-be-installed location, and it is stable to mount.

With the abovementioned structure, the motor of the punching-free electric mounting unit outputs a driving force, and then the decelerating mechanism connected at the output end of the motor outputs the speed of an output shaft of the motor to the connecting block at a low rate, such that the movement speed of the connecting block when driven is ensured to be proper, and the movement speed of the pushing block is further ensured to be proper, thus satisfying the fine tuning requirements in installation of the curtain rod, making adjustment precision higher, and preventing damage caused by the pushing block colliding on the lateral wall of the to-be-installed location at a higher rate after driven by the motor that runs excessively fast.

Further, the connecting block and the pushing block are in threaded connection.

Further, the motor comprises a control unit, and a button is provided on the control circuit board of the control unit for turning on/off the motor.

Further, the housing comprises a first connecting box and a second connecting box that can spliced together. The lateral wall of the first connecting box is provided with a through hole in which the button of the control unit is mounted. The motor and the decelerating mechanism can be accommodated in the second connecting box.

Further, the first connecting box comprises at least two accommodating cavities respectively for accommodating the control circuit board of the motor as well as the connecting block and the pushing block. One surface of the first connecting box facing to the decelerating mechanism is provided with a through hole through which the output shaft of the decelerating mechanism penetrates to be connected with the connecting block.

Further, the decelerating mechanism comprises a set of first-stage gears and a set of second-stage gears, with the axes of the two sets of gears parallel to each other. The first-stage gears and the second-stage gears are mutually meshed. The decelerating mechanism also comprises a first-stage gear of which one end is connected with the output end of the motor and the other end is connected with the first-stage gear closest to the motor. The set of first-stage gears at least comprises two gears different in diameter, the gear with a bigger diameter and the gear with a smaller diameter are spaced apart and coaxially arranged, and the gear closest to the motor is the gear with a smaller diameter. The set of second-stage gears at least comprises two gears different in diameter, the gear with a bigger diameter and the gear with a smaller diameter are spaced apart and coaxially arranged, and the gear closest to the motor is the gear with a bigger diameter. The first-stage gear furthest away from the motor is connected with a drive output shaft.

Further, the decelerating mechanism also comprises a second-stage gear I parallel to the first-stage gear. The second-stage gear I is connected to the second-stage gear closest to the motor. The second-stage gear furthest away from the motor is connected with a second-stage gear II.

Further, the set of first-stage gears comprise six gears that are spaced apart in a small-large-small-large order based on the diameter size along the direction gradually away from the motor. That is to say, the six gears are successively arranged as follows: first-stage small gear One, first-stage large gear One, first-stage small gear Two, first-stage large gear Two, first-stage small gear Three, and first-stage large gear Three. The first-stage large gear One and the first-stage small gear Two form a first-stage duplex gear One, and the first-stage large gear Two and the first-stage small gear Three form a first-stage duplex gear Two. The set of second-stage gears comprise six gears that are spaced apart in a large-small-large-small order based on the diameter size along the direction gradually away from the motor. That is to say, the six gears are successively arranged as follows: second-stage large gear One, second-stage small gear One, second-stage large gear Two, second-stage small gear Two, second-stage large gear Three, and second-stage small gear Three. The second-stage large gear One and the second-stage small gear One form a second-stage duplex gear One, the second-stage large gear Two and the second-stage small gear Two form a second-stage duplex gear Two, and the second-stage large gear Three and the second-stage small gear Three form a second-stage duplex gear Three. The first-stage gears and the second-stage gears are respectively meshed according to the above arrangement sequence. Further, one surface of the pushing block facing to the lateral wall where the curtain rod is to be installed is a coarse surface.

The other object of the present invention is to provide a curtain rod with the punching-free electric mounting unit. The punching-free electric mounting unit is at least mounted on one end of the curtain rod.

FIG. 1 shows a curtain rod with the punching-free electric mounting unit.

The present invention provides a punching-free electric mounting unit. As shown in FIGS. 2 and 3, it comprises a housing in which a motor 25 is mounted. The output end of the motor 25 is provided with a decelerating mechanism 27, a connecting block 22 and a pushing block 21 in turn. The motor 25 outputs a driving force to drive the connecting block 22, and then the connecting block 22 drives the pushing block 21 to move. The fine tuning of the length of the curtain rod is realized through outward movement of the pushing block 21, so the curtain rod can be stably mounted.

When the punching-free electric mounting unit of the present invention is used, the motor 25 is started to output a driving force, the decelerating mechanism 27 connected at the output end of the motor 25 outputs the speed of an output shaft of the motor to the connecting block 22 at a low rate, so that the movement speed of the connecting block 22 when driven is ensured to be proper, and the movement speed of the pushing block 21 is further ensured to be proper, thereby satisfying the fine tuning requirements in installation of the curtain rod, making adjustment precision higher, and preventing damage caused by the pushing block 21 colliding on the lateral wall of the to-be-installed location at a high rate after driven by the motor 25 that runs excessively fast.

As a further improved embodiment, as shown in FIG. 3, the connecting block 22 and the pushing block 21 are in threaded connection. In particular, the connecting block 22 is cylinder-shaped and has external threads, the pushing block 21 has internal threads matched with the external threads, or the external threads and the internal threads are placed in reverse. That is to say, the connecting block 22 has a connecting cavity of which the wall is provided with the external threads, the pushing block 21 is provided with the internal threads matched with the external threads (the reverse thread arrangement is not shown in the figure). The action process is that the connecting block 22 is driven by the driving force of the motor 25 to rotate, and then drives the pushing block 21 to rotate under the effect of threaded connection, so that the whole lengths of the connecting block 22 and the pushing block 21 change so as to achieve length adjustment.

As a further improved embodiment, as shown in FIG. 3, the motor 25 comprises a control unit, an electricity access unit and so on. The control circuit board 24 of the control unit is provided with a button for closing or opening the motor 25.

As a further improved embodiment, as shown in FIG. 3, the housing comprises a first connecting box 23 and a second connecting box 26 mutually coverable to each other. The lateral wall of the first connecting box 23 is provided with a through hole in which the button of the control unit is arranged. The motor 25 and the decelerating mechanism 27 can be contained in the second connecting box 26.

As a further improved embodiment, as shown in FIGS. 3 to 5, the first connecting box 23 has at least two accommodating cavities 232, 233 respectively for accommodating the control circuit board 24 as well as the connecting block 22 and the pushing block 21. One surface of the first connecting box 23 facing to the decelerating mechanism 27 is provided with a through hole 231 through which the output shaft of the decelerating mechanism 27 penetrates to be connected with the connecting block 22. In an improved embodiment, the control circuit board 24 is contained in the accommodating cavity 232, the connecting block 22 and the pushing block 21 are contained in the accommodating cavity 233, but the accommodating cavity 232 and the accommodating cavity 233 are integrated on the first connecting box 23. Therefore, a control unit and a drive unit are separated so as to not only prevent mutual interference but also ensure integrity of the mounting unit.

As a further improved embodiment, as shown in FIG. 6, the decelerating mechanism 27 comprises a set of first-stage gears and a set of second-stage gears, with the axes (extending along the length direction of the curtain rod) of the two sets of gears parallel to each other. The first-stage gears and the second-stage gears are mutually meshed. The decelerating mechanism 27 also comprises a first-stage gear 272 of which one end is connected with the output end 271 of the motor and the other end is connected with the first-stage gear closest to the motor 25. The set of first-stage gears at least comprises two gears different in diameter, the gear with a bigger diameter and the gear with a smaller diameter are spaced apart and coaxially arranged, and the gear closest to the motor 25 is the gear with a smaller diameter. The set of second-stage gears at least comprises two gears different in diameter, the gear with a bigger diameter and the gear with a smaller diameter are spaced apart and coaxially arranged, and the gear closest to the motor 25 is the gear with a bigger diameter. The first-stage gear furthest away from the motor 25 is connected with a drive output shaft 28. The driving force output by the motor 25 is transferred to the first-stage gear 272 through the output end 271 of the motor, the first-stage gear 272 drives the first-stage gear connected therewith to rotate, the first-stage gear drives a second-stage gear to rotate, and the second-stage gear drives the first-stage gear in turn. Therefore, by virtue of match of gear diameter and gear ratio, when the rotation speed output by the motor is transferred to the drive output shaft 28, output rate is lowered.

As a further improved embodiment, as shown in FIG. 6, the decelerating mechanism 27 also comprises a second-stage gear I 273a parallel to the first-stage gear 272. The second-stage gear I 273a is connected to the second-stage gear closest to the motor 25. The second-stage gear furthest away from the motor 25 is connected with a second-stage gear II 273b. The second-stage gear I 273a and the second-stage gear II 273b are mounted on the lateral wall of the housing, so operation stability of the second-stage gears is improved.

As a further improved embodiment, as shown in FIG. 6, the set of first-stage gears comprise six gears that are spaced apart in a small-large-small-large-small-big order based on the diameter size along the direction gradually away from the motor 25. That is to say, the six gears are successively arranged as follows: first-stage small gear One 275a, first-stage large gear One 275b, first-stage small gear Two 277a, first-stage large gear Two 277b, first-stage small gear Three 279a, first-stage large gear Three 279b. The first-stage large gear One 275b and the first-stage small gear Two 277a form a first-stage duplex gear One, and the first-stage large gear Two 277b and the first-stage small gear Three 279a form a first-stage duplex gear Two. The set of second-stage gears comprise six gears that are spaced apart in a big-small-large-small-large-small order based on the diameter size along the direction gradually away from the motor 25. That is, the six gears are successively arranged as follows: second-stage large gear One 274a, second-stage small gear One 274b, second-stage large gear Two 276a, second-stage small gear Two 276b, second-stage large gear Three 278a, and second-stage small gear Three 278b. The second-stage large gear One 274a and the second-stage small gear One 274b form a second-stage duplex gear One, the second-stage large gear Two 276a and the second-stage small gear Two 276b form a second-stage duplex gear Two, and the second-stage large gear Three 278a and the second-stage small gear Three 278b form a second-stage duplex gear Three. The first-stage gears and the second-stage gears are respectively meshed according to the above arrangement sequence, i.e., the first-stage small gear One 275a and the second-stage large gear One 274a are meshed, the first-stage large gear One 275b and the second-stage small gear One 274b are meshed . . . and so on. In use, the driving force output by the motor 25 is transferred to the first-stage gear 272 through the output end 271 of the motor, the first-stage gear 272 drives the first-stage small gear One 275a to rotate, the first-stage small gear One 275a drives the second-stage large gear One 274a and the second-stage small gear One 274b (i.e., the second-stage duplex gear One) to rotate through meshing with the second-stage large gear One 274a; the second-stage small gear One 274b drives the first-stage large gear One 275b and the first-stage small gear Two 277a (i.e., the first-stage duplex gear One) to rotate through meshing with the first-stage large gear One 275b, in accordance with the sequence, the first-stage duplex gear One drives the second-stage duplex gear Two to rotate, then the second-stage duplex gear Two drives the first-stage duplex gear Two to rotate, the next-stage duplex gear Two drives the second-stage duplex gear Three to rotate, and finally the second-stage duplex gear Three drives the first-stage large gear Three 279b. Therefore, the driving force of the motor is output to the connecting block 22 through the drive output shaft 28 connected with the first-stage large gear Three 279b. In this process, after multi-stage deceleration, rotation speed output by the motor 25 is lowered, so that rotation speed of the connecting block 22 is steady and controllable.

As a further improved embodiment, one surface of the pushing block 21 facing to the lateral wall on which the curtain rod is to be installed is a coarse surface, for increasing a friction force with the lateral wall of the to-be-installed location, improving mounting fastness.

The present invention also provides a curtain cord with the punching-free electric mounting unit. The punching-free electric mounting unit is at least mounted on one end of the curtain rod. As shown in FIG. 1, one end of the main body 1 of the curtain rod is provided with the punching-free electric mounting unit 2, and the lateral surface on which the main body 1 of the curtain rod and a connector 4 of a reel 3 are connected is provided with a through hole for protrusion of the pushing block 21 of the punching-free electric mounting unit, so length of the curtain rod is adjusted.

The curtain rod with the punching-free electric mounting unit of the present invention is convenient to use. After the curtain rod is placed on the to-be-installed location, if its length needs to be adjusted, the motor 25 is started, the pushing block 21 is protruded under the effect of the driving force of the motor 25, and the motor is closed once the desired length is reached, by this time, the curtain rod can be steadily mounted.

Otherwise particularly stated, materials, reagents and experimental equipment involved in the embodiments of the present invention belong to commercially available products of rod parts.

The described above is merely the preferred embodiments of the present invention. It should be pointed out that, for persons having ordinary skill in the art, any improvements and modifications made without departing from the core technology of the present invention are appreciated.
