Technical Field

[0001] This utility model relates to the field of door lock technology, and in particular to a handle assembly installation structure. Background Technology

[0002] Door locks are a common type of door security device used to prevent unauthorized intrusion. They typically include an inner door handle and an outer door handle. The inner door handle is equipped with a deadbolt mechanism, while the outer door handle is equipped with a locking mechanism that is linked to the deadbolt mechanism. The deadbolt mechanism can lock the outer door handle to prevent strangers from opening the door from the outside. Usually, a key needs to be inserted to activate the locking mechanism in order to unlock the deadbolt mechanism and lock the outer door.

[0003] Whether it is an inner door handle or an outer door handle, it includes a connector fixed on the lock seat and a square bushing that rotates relative to the connector. The square bushing rotates with the inner door handle. Since there is no positioning structure between the connector and the square bushing, if the two are not properly assembled, the inner door handle parts will become loose or rotate unresponsively.

Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0027] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0028] like Figures 1 to 9The illustrated handle assembly installation structure includes a lock base 1 and an inner door handle 2 that rotates relative to the lock base 1. The lock base 1 has a first mounting cavity 3, within which a connector 5, a square bushing 4, and a deadbolt mechanism 6 are disposed. The deadbolt mechanism 6 is linked to the locking mechanism of the outer door handle (not shown) via a linkage rod. The connector 5 is fixed to the lock base 1. The first mounting cavity 3 has a positioning groove 7 for installing the square bushing 4. The square bushing 4 is at least partially confined within the positioning groove 7 and rotates synchronously with the inner door handle 2. The square bushing 4 is inserted into the connector 5, and the square bushing 4 and the connector 5 are rotatably engaged. The assembly also includes components sleeved on the connector. The pressure plate 8 outside the connector 5 is provided with a blocking part 9. The pressure plate 8 and the blocking part 9 are directly or indirectly attached. The pressure plate 8 is fixedly connected to the inner wall of the first mounting cavity 3 and locks the connector 5 and the square shaft sleeve 4 in the first mounting cavity 3. The mounting structure in this embodiment can be applied to the inner door handle 2 or the outer door inner door handle 2. The difference is that the structure of the anti-locking mechanism 6 and the locking mechanism of the square shaft sleeve 4 in the inner door handle 2 or the outer door handle is different from that of the connector 5. The locking mechanism and the anti-locking mechanism 6 are linked by a linkage rod (not shown in the figure). This is the prior art, so it is not described in detail. The core of this application is the internal mounting structure of the handle.

[0029] During assembly, the square shaft sleeve 4 is aligned with the positioning groove 7 of the inner door handle 2, and the connecting piece 5 is sleeved on the outside of the square shaft sleeve 4. This allows for quick positioning and installation of the internal parts of the inner door handle 2. The pressure plate 8 makes the connecting piece 5 and the square shaft sleeve 4 fit tightly together, preventing axial slippage between the connecting piece 5 and the square shaft sleeve 4 when the inner door handle 2 moves. This ensures that the parts do not loosen, and the inner door handle 2 rotates smoothly and reliably.

[0030] The bottom wall of the first mounting cavity 3 is recessed downward to form the positioning groove 7. Positioning parts 10 are provided on both sides of the bottom wall of the first mounting cavity 3 adjacent to the positioning groove 7. The positioning parts 10 are formed by the upward protrusion of the bottom wall of the first mounting cavity 3. The positioning parts 10 are located outside the positioning groove 7 and have threaded holes 11. The pressure plate 8 has through holes 12 corresponding to the threaded holes 11. They are fastened by screws. In this embodiment, four positioning parts 10 are provided and located at the four corners of the inner wall of the first mounting cavity 3. The end face of the blocking part 9 facing away from the square bushing 4 is lower than the outer end face of the positioning part 10. A washer or gasket needs to be fitted onto the connecting piece 5 to make the outer end face of the positioning part 10 flush with the gasket; alternatively, if no washer or gasket is installed, the end face of the blocking part 9 facing away from the square bushing 4 is flush with the outer end face of the positioning part 10.

[0031] Two lugs 13 are symmetrically arranged on the outside of the connector 5. A torsion spring 14 is provided on the outer sleeve of the connector 5, and the two free ends of the torsion spring 14 are respectively placed on the two lugs 13. The two free ends of the torsion spring 14 correspond to two of the positioning parts 10. When the inner door handle 2 rotates relative to the lock seat 1, one of the positioning parts 10 pushes one of the free ends of the torsion spring 14 to twist and store energy. After the inner door handle 2 is released, it can be reset under the action of the torsion spring 14.

[0032] The rotating part 16 and the mounting part 15 are coaxially arranged, and the rotating part 16 is provided with a shaft hole for mounting the square shaft. The connecting part is sleeved on the outside of the rotating part 16 and the inner end face of the connecting part is in contact with the mounting part 15. The mounting part 15 is provided with an arc-shaped surrounding plate 18 on the side facing the rotating part 16, and the inner wall of the arc-shaped surrounding plate 18 is in contact with the outer wall of the rotating part 16.

[0033] The mounting part 15 is integrally formed with two positioning ears 17, and the two positioning ears 17 are symmetrically arranged on the mounting part 15. The mounting part 15 is fixed in the positioning groove 7, and the shape of the positioning groove 7 is adapted to the shape of the mounting part 15. The positioning ears 17 are fastened to the positioning groove 7 by screws.

[0034] The mounting part 15 has a movable cavity 19 communicating with the shaft hole. The locking mechanism 6 includes an operating member 21, a driving member 22, and a push button 23. The two ends of the operating member 21 are respectively provided as a gear part 24 and an operating shaft 25. The operating shaft 25 is rotatably mounted in the movable cavity 19. One end of the linkage rod is connected to the end of the operating shaft 25 located in the movable cavity 19. The driving member 22 has a rack part 26 that cooperates with the gear part 24. The inner door handle 2 has a second mounting cavity 27 on the side opposite to the first mounting cavity 3. The rack part 26 The push button 23 is fixed to the drive member 22 and is externally mounted on the inner door handle 2. The inner door handle 2 has a movable hole 20 corresponding to the push button 23. The push button 23 is slidably mounted in the movable hole 20. Moving the push button 23 can cause the rack part 26 to slide and drive the gear part 24 to rotate, thereby driving the operating shaft 25 and the linkage rod to rotate, so that the locking mechanism of the outer door handle is locked or unlocked.
