Description

Technical Field

[0001] The technical field of the present invention relates to an anti-theft door stop structure, and in particular to a rotary-engaged telescopic door stop device. Background Art

[0002] In recent years, more and more homes have been burglarized, so various types of door anti-theft measures have been developed. The most common anti-theft measure is to use a door stopper rod to be placed under the door handle inside the house. The existing door stopper rod generally includes: a rod body, a stopper and a support member. The stopper of the rod body is pressed against the door handle, and the support member is supported on the ground, so that the rod body is supported between the door and the ground at a slightly inclined angle, so that the door handle cannot be turned, preventing criminals from unlocking the door and entering from outside. However, the existing door stopper rod is usually placed by the door when not in use, so that it can be taken when in use, but this storage method is prone to accidental collision when the user walks. Therefore, there are still many deficiencies in the storage of the existing door stopper rod that need to be solved. In addition, the distance between the door handle and the ground of each home is different, so the door stopper rod must have the function of being able to retract and adjust the length in order to be suitable for various door bodies. Summary of the invention

[0003] The main technical problem to be solved by the present invention is to overcome the above-mentioned defects of the prior art and provide a retractable door stop device with a rotary joint. The door stop device has an assembly and disassembly function through a rotary assembly method, which is easy to store and can adjust the length to suit different door bodies.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A rotatably engaged telescopic door stop device comprises: a door stop rod group, comprising a first door stop rod and a second door stop rod that are assembled and disassembled with each other; a coupling tube group, comprising a first coupling tube body and a second coupling tube body that are respectively assembled and disassembled with the first door stop rod and the second door stop rod, the first coupling tube body and the second coupling tube body being butted against each other and having corresponding clamping parts and clamping grooves, both ends of the clamping grooves extending along the inner wall of the second coupling tube body to form rotating grooves, when the clamping parts are clamped into the clamping grooves and rotated into the rotating grooves, the first coupling tube body and the second coupling tube body are positioned with each other and cannot rotate, so that the first door stop rod is engaged with the second door stop rod; a telescopic tube group, pivotally arranged inside the door stop rod group and having a door stop member and a support member at the top and bottom ends respectively.

[0006] Among them, the thickness of the second stopping portion is thinner than that of the first stopping portion. When the first base and the second base of the first joining tube body and the second joining tube body are in contact with each other, the clamping portion of the first joining tube body is screwed into the rotating groove from the clamping groove of the second joining tube body through the rotating space, and the second clamping section of the clamping portion forms a clamping relationship with the second stopping portion, so that the first joining tube body and the second joining tube body are positioned relative to each other.

[0007] Among them, an elastic pressing component is provided at a position on the inner wall surface of the second joint pipe body opposite to the rotary cutting groove and close to the closed end. By pressing the outer surface of the first clamping section of the clamping part through the elastic pressing component, the first joint pipe body and the second joint pipe body are clamped more tightly.

[0008] The beneficial effect of the present invention is that the door stopper device has the functions of assembly and disassembly through a rotary assembly method, which is convenient for storage and can adjust the length to be suitable for different door bodies.

[0046] Please refer to Figures 1 to 12 As shown, the present invention is a rotary joint telescopic door stopper device. The door stopper device 1 is used to support between the door handle T and the ground G to prevent the door body T1 from being opened from the outside of the house, and includes:

[0047] The door stop lever set 2 is hollow and has a first door stop lever 20 and a second door stop lever 21 that are detachably assembled with each other. The first door stop lever 20 and the second door stop lever 21 respectively have corresponding first engaging holes 200 and second engaging holes 210, and fixing holes 201, 211 and several positioning holes 202, 212 are arranged on the rod surfaces of the first door stop lever 20 and the second door stop lever 21.

[0048] The joint pipe set 3 has a first joint pipe body 30 and a second joint pipe body 31 that are respectively detachably assembled to the first door stop lever 20 and the second door stop lever 21. The first joint pipe body 30 and the second joint pipe body 31 respectively have corresponding first bases 300 and second bases 310. The upper and lower sides of the first base 300 have a clamping portion 301 and a first engaging portion 302, and the upper side of the second base 310 has a second engaging portion 311. For further explanation, please refer to Figure 2 As shown, the first engaging portion 302 and the second engaging portion 311 have fixing portions 3020, 3110 corresponding to the fixing holes 201 of the first door stop lever 20 and the second door stop lever 21. Among them, the clamping portion 301 of the first joint pipe body 30 is arranged in an inverted U shape on the upper surface of the first base 300, and the clamping portion 301 has two first clamping segments 303 and a second clamping segment 304 connected between the two first clamping segments 303. The two first clamping segments 303 are longitudinally arranged on the upper surface of the first base 300, so that a rotation space 305 is formed between the second clamping segment 304 and the upper surface of the first base 300. The second base 310 of the second joint pipe body 31 has two corresponding positioning pieces 312. A clamping groove 313 corresponding to the clamping portion 301 of the first joint pipe body 30 is formed between the two adjacent positioning pieces 312. The two positioning pieces 312 have a stepped and connected first stop portion 314 and second stop portion 315. The two sides of the second stop portion 315 have a straight end face 316 and a curved end face 317. A rotation groove 318 communicating with the clamping groove 313 is formed between the curved end face 317 and the inner wall surface of the second joint pipe body 31. The end of the rotation groove 318 forms a closed end 319, and the rotation groove 318 follows the inner wall surface of the second joint pipe body 31.

[0049] The telescopic pipe set 4 has a first telescopic rod 40 and a second telescopic rod 41 that are respectively pivotally arranged inside the first door stop lever 20 and the second door stop lever 21. The ends of the first telescopic rod 40 and the second telescopic rod 41 away from the first door stop lever 20 and the second door stop lever 21 respectively have a supporting member 400 and a door stop member 410, and the first telescopic rod 40 and the second telescopic rod 41 respectively have positioning portions 401, 411 corresponding to the several positioning holes 202, 212 of the first door stop lever 20 and the second door stop lever 21.

[0050] During assembly, the first telescopic rod 40 and the second telescopic rod 41 are respectively pivotally arranged inside the first door stop rod 20 and the second door stop rod 21, and the positioning parts 401 and 411 of the first telescopic rod 40 and the second telescopic rod 41 are respectively positioned in the positioning holes 202 and 212 of the first door stop rod 20 and the second door stop rod 21.

[0051] And, as Figure 4 shown, the first joint part 302 of the first joint pipe body 30 is assembled to the first joint hole 200 of the first door stop rod 20, so that the first base 300 abuts against the port of the first joint hole 200, and the clamping part 301 is exposed outside, and is fixed to the fixing hole 201 of the first door stop rod 20 by the fixing part 3020, so that the first joint pipe body 30 and the first door stop rod 20 are mutually jointed. And the second base 310 of the second joint pipe body 31 is assembled to the second joint hole 210 of the second door stop rod 21, so that the second base 310 abuts against the port of the second joint hole 210, and is fixed to the fixing hole 201 of the second door stop rod 21 by the fixing part 3110, so that the second joint pipe body 31 and the second door stop rod 21 are mutually jointed.

[0052] Next, the first joint pipe body 30 and the second joint pipe body 31 are mutually jointed, so that the first base 300 and the second base 310 are in abutting contact. At this time, the clamping part 301 of the first joint pipe body 30 is snapped into the clamping groove 313 of the second joint pipe body 31 (as Figure 6 shown). Subsequently, the first door stop rod 20 and the second door stop rod 21 are simultaneously rotated in opposite directions (in this embodiment, the first door stop rod 20 is rotated clockwise and the second door stop rod 21 is rotated counterclockwise). When the clamping part 301 of the first joint pipe body 30 is snapped into the clamping groove 313 of the second joint pipe body 31 through the rotation space 305 and screwed into the rotation groove 318 (as Figure 7 shown), the inner side of the second clamping section 304 of the clamping part 301 is tightly clamped on the upper side of the second stopping part 315 of the positioning piece 312. After the first joint pipe body 30 and the second joint pipe body 31 form a limiting relationship, the assembly of the first door stop rod 20 and the second door stop rod 21 can be completed. In this embodiment, the first joint pipe body 30 and the second joint pipe body 31 and the first door stop rod 20 and the second door stop rod 21 can be of a joint structure, or can also be of an integral structure.

[0053] In use, when adjusting the length of the door stopper device 1, press the positioning parts 401 and 411 of the first telescopic rod 40 and the second telescopic rod 41 to disengage them from the positioning relationship with the positioning holes 202 and 212, so that the first telescopic rod 40 and the second telescopic rod 41 can extend and contract relative to the first door stopper rod 20 and the second door stopper rod 21. In other words, by positioning the positioning parts 401 and 411 in the positioning holes 202 and 212 at different positions, the effect of adjusting the lengths of the first telescopic rod 40 and the second telescopic rod 41 can be achieved. After adjusting the length, the abutting member 400 of the first telescopic rod 40 can be abutted against the ground G, and the door stopper member 410 of the second telescopic rod 41 can be abutted against the doorknob T (as Figure 8 shown), thereby preventing thieves from opening the door from outside the house.

[0054] It is worth mentioning that the structures of the door bodies T1 of each household are different, and the distances between the doorknobs T of the door bodies T1 and the ground G are also different. From the above description, it can be known that the door stopper device 1 of the present invention has an assembling and disassembling function rather than an integral rod structure. Therefore, when disassembling the first door stopper rod 20 and the second door stopper rod 21 of the door stopper device 1, rotate the first door stopper rod 20 and the second door stopper rod 21 in opposite directions at the same time (in this embodiment, the first door stopper rod 20 rotates counterclockwise and the second door stopper rod 21 rotates clockwise), so that the clamping portion 301 of the first joint pipe body 30 rotates out from the position of the rotary cutting groove 318 of the second joint pipe body 31 to the position of the clamping cutting groove 313, and the second clamping section 304 of the clamping portion 301 is disengaged from the clamping relationship with the second stopping portion 315 of the positioning piece 312. After the limiting relationship between the first joint pipe body 30 and the second joint pipe body 31 is released, the first door stopper rod 20 and the second door stopper rod 21 can be disassembled. In addition, the user can further add a third door stopper rod 22 between the first door stopper rod 20 and the second door stopper rod 21 according to actual needs (as Figure 9 shown), so as to lengthen the overall length of the door stopper rod group 2, and the assembling and disassembling method between the third door stopper rod 22 and the first door stopper rod 20 and the second door stopper rod 21 is the same as the foregoing, and please allow the applicant not to repeat it.

[0055] In addition, an elastic pressing assembly 5 is provided on the inner wall surface of the second joint pipe body 31 at a position close to the closed end 319 of the rotary cutting groove 318. Further, a receiving groove 3100 is formed on the inner wall surface of the second joint pipe body 31. The elastic pressing assembly 5 has an elastic member 50 and a pressing member 51 connected to each other. The elastic member 50 is fixedly connected in the receiving groove 3100 and a part of the area of the pressing member 51 is exposed in the rotary cutting groove 318 (as Figure 10 shown). When the clamping portion 301 of the first joint pipe body 30 rotates into the rotary cutting groove 318 from the position of the clamping cutting groove 313, the outer surface of the first clamping section 303 of the clamping portion 301 is pressed against the pressing member 51 of the elastic pressing assembly 5 (as Figure 12As shown. In other words, the elastic pressing component 5 is used to enhance the tight clamping relationship between the first joint tube body 30 and the second joint tube body 31.

[0056] The above are only the preferred embodiments of the present invention, and do not impose any formal limitations on the present invention. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention still fall within the scope of the technical solutions of the present invention.
