The application claims priority to Chinese patent application No. 2023109409516, filed on Jul. 28, 2023, the entire contents of which are incorporated herein by reference.
The present disclosure relates to the technical field of hose locking, and more particularly to a hose telescopic device with a locking structure.
In the prior art, a hose is widely used in industry and everyday life, and a drawing hose is wound and received by means of a receiving assembly. However, the conventional receiving assembly has only a drawing and recycling function, and cannot lock the drawing hose, resulting in a narrow scope of application for drawing hose.
Therefore, how to provide a hose telescopic device with a locking structure to lock the hose after drawing and expand the scope of application for drawing hose becomes an urgent technical problem to be solved.
The technical problem to be solved by the present disclosure is how to provide a hose telescopic device with a locking structure to lock the hose after drawing and expand the scope of application for drawing hose.
To this end, according to a first aspect, the present disclosure discloses a hose telescopic device with a locking structure, including: a hose, a receiving assembly and a locking structure, wherein one end of the hose is received in the receiving assembly, and the other end of the hose passes through the receiving assembly and the locking structure successively, and the locking structure includes a locking seat, the locking seat being provided with several locking pawls having elasticity, the locking pawls being used for locking the hose, and the locking seat being sheathed with a locking piece used for tightening or loosening the locking pawls.
The present disclosure further provides that the locking piece includes a locking ring, the locking ring being provided therein with locking latches adapted to the locking pawls.
The present disclosure further provides that the locking pawls are provided with a first ramp and the locking latches are provided with a second ramp adapted to the first ramp.
The present disclosure further provides that the locking ring is provided with a shift lever for conveniently shifting the locking ring for rotation.
The present disclosure further provides that the shift lever is integrally formed with the locking ring.
The present disclosure further provides that the locking structure further includes a ferrule sleeved on the locking seat, the ferrule being used for clamping and limiting the locking seat.
The present disclosure further provides that the locking seat is screwed with a fastening seat for fastening the locking structure.
The present disclosure further provides that the locking seat is sheathed with a wear ring abutting against the locking piece.
The present disclosure further provides that the receiving assembly includes a receiving plate, a first box board and a second box board, the first box board being detachably connected to the second box board, the receiving plate being rotatably connected to the first box board and the second box board, respectively, the hose being wound around the receiving plate, and a winding spring being mounted on one side of the receiving plate.
The present disclosure further provides that a plastic card is rotatably connected to the first box board, one end of the plastic card is hooked with a first spring, the first spring is fastened to the first box board by a fastening screw, the receiving plate is provided with a latch portion and a smooth portion, and the plastic card is clamped with the latch portion.
The present disclosure has the following advantageous effects: the locking seat is sheathed with a locking piece for tightening or loosening the locking pawls, and the locking pawls lock the hose, to provide a hose telescopic device with a locking structure, which is convenient for locking the hose after drawing, and expands the scope of application for drawing hose.
In order to more clearly state the detailed description of the present disclosure or the technical scheme in the prior art, the following is a brief introduction of the drawings required to be used in the description of the detailed description of the present disclosure or the prior art. It is obvious that the drawings in the description below are some embodiments of the present disclosure, and other drawings may be obtained by a person skilled in the art without involving any inventive effort.

In order to make the objects, technical schemes and advantages of the present disclosure more clearly understood, the present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the particular embodiments described herein are merely illustrative of the present disclosure and are not intended to be limiting.
In the description of the present disclosure, it should be noted that, unless expressly specified or limited otherwise, the terms “mounted”, “connecting”, and “connected” are to be interpreted broadly, e.g. either fixedly or detachably, or integrally connected: may be mechanically or electrically connected: may be directly or indirectly connected through an intermediate medium, and may also be connected within two elements, and may be connected wirelessly or wiredly. The specific meaning of the above terms in the present disclosure may be understood in detail by those skilled in the art.
In the description of the present disclosure, it should be noted that the terms “central”, “upper”, “lower”, “left”, “right”, “vertical”, “horizontal”, “inner”, “outer”, and the like designate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, are merely for convenience in describing the present disclosure and to simplify the description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus should not be construed as limiting the present disclosure. Furthermore, the terms “first”, “second”, and “third” are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Furthermore, the technical features involved in the different embodiments of the present disclosure described below may be combined with each other as long as they do not conflict with each other.
The embodiment of the present disclosure discloses a hose telescopic device with a locking structure, as shown in
It should be noted that the locking seat 31 is sheathed with a locking piece 32 for tightening or loosening the locking pawls 311, and the locking pawls 311 lock the hose 1, to provide a hose telescopic device with a locking structure, which is convenient for locking the hose 1 after drawing, and expands the scope of application for drawing hose 1.

It should be noted that when one end of the plastic card 25 is clamped with the latch portion 211, the winding spring 24 is prevented from driving the receiving plate 21 to rotate; when one end of the plastic card 25 is located at the smooth portion 212, the winding spring 24 facilitates to drive the receiving plate 21 to rotate, so that the hose 1 may be retracted.
Working principle: the locking seat 31 is sheathed with a locking piece 32 for tightening or loosening the locking pawls 311, and the locking pawls 311 lock the hose 1, to provide a hose telescopic device with a locking structure, which is convenient for locking the hose 1 after drawing, and expands the scope of application for drawing hose 1.
It is to be understood that the above-described embodiments are merely illustrative for clarity and are not restrictive of the embodiments. For a person of ordinary skill in the art, other variations and modifications are possible in the light of the above description. All embodiments need not be, and cannot be, exhaustive herein.
