1. Field of the Invention

The present invention relates to a technical field of anti-theft door stop rod device, and more particularly to a door stop rod with a warning function.

2. Description of the Related Art

Many types of anti-theft countermeasures for doors are available in markets, and the most common one is knob. However, the knob is easy to be opened and the key of the knob is easy to leak, so the property in the house may be easy to be stolen or people in the house are easily bothered or harassed even the house is installed with the knob. Therefore, many people install door stop rods on the inner side of the door to protect the safety of people and property indoors.

Many companies also develop door stop devices for consumers' selection. For example, Taiwan utility model patent No. M413011 discloses that the door stop rod can also e used as a crutch to provide better functionality. Another example is Taiwan utility model patent No. M367224, which further provides a solution to the inconvenience of storing and stowing conventional doorstop devices, so as to achieve better storage convenience.

However, the above-mentioned patents only provide the conventional door stop rod with extension peripheral use function, other than anti-theft function, for the effect of convenient use; they have not further improved the anti-theft function of the convention door stop rod, and it may be insufficient to resist the increasingly renovated theft skills by only using the stop rod to assist anti-theft effect of the door lock, and the door lock is still easy to be broken by thieves and cannot protect the safety of lives and property of people indoors.

SUMMARY OF THE INVENTION

An objective of the present invention is to dispose an early warning device in a clamping holder of a stop rod to detect outside vibration; in response to the detected vibration, the early warning device can make a warning sound to warn people indoors to respond countermeasures, call police or ask for help as soon as possible, thereby effectively protecting the safety of lives and property.

In order to achieve aforementioned objective and effect, the present invention provides a door stop rod with a warning function for anti-theft assistance on a door lock disposed on a door panel, and the door stop rod includes a clamping holder and an early warning device. The clamping holder includes an accommodation chamber, and an assembly section and a door clamping part disposed on two opposite sides thereof. The assembly section is combined with an end of a stop rod, and the door clamping part includes a clamping part. The early warning device is disposed in the accommodation chamber, and includes a control circuit, a power supply device, a buzzer, and a vibration detection device which are electrically connected to each other. The control circuit can control the buzzer to make a warning sound when the vibration detection device detects outside vibration.

As shown in FIGS. 6 and 7, the door clamping part 23 can include two clamping sections 232 normally pivotally swung toward the approaching directions, so that the two clamping sections 232 can elastically clamp the door lock 11 with different size after the two clamping sections 232 are pivotally swung by elastic recovery. As shown in FIG. 7, in this embodiment, pivot pins 233 are inserted through and movably pivoted with the two clamping sections 232, respectively; torque springs 234 are inserted through and assembled with the pivot pins 233, respectively, so as to elastically push the two clamping sections 232 to pivotally swing toward the approaching directions in a normal status.

Furthermore, as shown in FIGS. 3 and 8, the stop rod 30 can include an inner tube 31 and an outer tube 32 which are telescopically mounted with each other, and the inner tube 31 is mounted with the assembly section 22 by an end, which is opposite to the outer tube 32, thereof. Furthermore, the assembly section 22 has a plurality of restraining ribs 221 protruded on the outer peripheral side thereof, and the inner tube 31 has a mounting hole 311 mounted with the assembly section 22, and a plurality of restraining grooves 312 axially arranged on an inner tube wall thereof; the plurality of restraining ribs 221 are respectively mounted in the plurality of restraining groove 312 to restrain a radial rotation, so as to strengthen the firmness of the clamping holder 20 clamping the door lock 11. The stop rod 30 includes a dowel pin 33 inserted through and assembled with the inner tube 31 and the assembly section 22 which are mounted with each other, so as to strengthen the firmness of the stop rod 30 combined with the clamping holder 20 to clamp the door lock 11.

As shown in FIG. 8, the inner tube 31 includes an elastic fastener 313 elastically exposed out of the outer surface thereof, the outer tube 32 includes a plurality of through holes arranged in interval to form a first locating hole group 321 and a second locating hole group 322. The second locating hole group 322 is arranged in parallel with and aside the first locating hole group 321, and each of the through holes of the second locating hole group 322 is disposed between any adjacent two of the through holes of the first locating hole group 321, and the elastic fastener 313 of the inner tube 31 is elastically exposed out of and engaged with one of the through holes of the first locating hole group 321 and the second locating hole group 322, so as to fasten a telescopic length of the inner tube 31 and the outer tube 32. With the arrangement of the first locating hole group 321 and the second locating hole group 322, the adjustment steps of the telescopic length of the inner tube 31 and the outer tube 32 can be increased effectively, so as to improve usability of the door stop rod of the present invention, and prevent the structural strength of the outer tube from being affected because of too close hole distance.
