[0022] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0024] This invention proposes a quick-connect fitting for handles, see reference. Figure 1 , 2 The system includes a positioning seat 1, which has a through hole 11 inside. One end of the positioning seat 1 has a movable cavity 12, which is connected to the through hole 11. The movable cavity 12 has a control hole 13 on its side wall.

[0025] Elastic positioning element 2, see Figure 3 It includes a connected positioning piece 21 and a snap-fit ​​spring piece 22. The positioning piece 21 and the snap-fit ​​spring piece 22 form an angle. The positioning piece 21 is provided with a positioning hole 211, and the snap-fit ​​spring piece 22 is provided with a snap-fit ​​hole 221. In the combined state, the snap-fit ​​spring piece 22 is located in the movable cavity 12 and above the control hole 13.

[0026] Positioning Set 3, see reference Figure 2 , 3 The positioning sleeve 3 has a positioning cavity 31 inside, and the positioning seat 1 is fixed in the positioning cavity 31. A common fixing method is to weld the positioning seat 1 and the positioning sleeve 3 to achieve a sleeved and fixed state. In the combined state, the positioning cavity 31 is connected to the movable cavity 12. The positioning piece 21 is fixed between the positioning cavity 31 and the positioning seat 1. The cavity wall of the positioning cavity 31 is provided with a first clearance hole 32.

[0027] The lock bar 4 has several locking grooves 41 on its surface. The lock bar 4 passes through the through hole 11, the locking hole 221, the positioning hole 211 and the first clearance hole 32 in sequence. The locking grooves 41 are used to engage with the locking hole 221.

[0028] In this connector, the locking spring 22 is used to lock the square rod 4. The principle is as follows: During insertion, the square rod 4 pushes the locking spring 22 to tilt towards the positioning plate 21. During the deformation of the locking spring 22, the locking effect between the locking groove 41 and the locking hole 221 weakens, and the locking spring 22 can rebound under its own deformation force. At this time, the locking spring 22 will not hinder the insertion of the square rod 4. When the square rod 4 is subjected to an outward pulling force, the locking spring 22 tends to move away from the positioning plate 21. At this time, the locking groove 41 and the locking hole 221 always maintain a tight fit. Since the position of the positioning plate 21 is fixed, the positioning plate 21 will have a pulling effect on the locking spring 22, thereby restricting the outward movement of the square rod 4. This connector can achieve the fixing effect of the square rod 4 without the use of bolts, avoiding various problems caused by the use of bolts.

[0029] When disassembling this connector, the user inserts a thin rod into the control hole 13 to pry the snap-fit ​​spring 22, causing the snap-fit ​​spring 22 to disengage from the lock bar 4, thus allowing the lock bar 4 to be pulled out, making the operation simpler.

[0030] See Figure 2 The movable cavity 12 is provided with a limiting boss 14 at the cavity opening. The positioning piece 21 is closely attached to the cavity opening of the movable cavity 12. The positioning piece 21 is provided with an abutting surface 212. The abutting surface 212 abuts against the limiting boss 14 to prevent the elastic positioning piece 21 from deflecting from the positioning seat 1, and to ensure that the snap-fit ​​spring piece 22 is always above the control hole 13 so that the user can perform subsequent disassembly operations.

[0031] See Figure 2 The cavity wall of the movable cavity 12 is provided with a relief groove 121, and a connecting piece 23 is provided between the positioning piece 21 and the snap-fit ​​spring piece 22. In the combined state, the connecting piece 23 is located in the relief groove 121.

[0032] See Figure 1 , 3 To ensure a stable connection between the positioning sleeve 3 and the positioning seat 1, the positioning cavity 31 is relatively long to cover the entire movable cavity 12. To facilitate subsequent disassembly by the user, a second clearance hole 33 is also provided on the cavity wall of the positioning cavity 31, and the second clearance hole 33 is connected to the control hole 13.

[0033] A door handle includes a grip 5 and a connecting boss 51, see reference Figure 4 The connecting boss 51 has a connecting cavity 52, and the connecting cavity 52 has the aforementioned quick-connect connector for the handle fixed inside. The side wall of the connecting cavity 52 has a disassembly through hole 53, which communicates with the control hole 13.

[0034] The above description is only a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions that fall within the scope of the present invention are within the scope of protection of the present invention.
