[0027] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments and drawings, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0028] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.

[0030] The handle 2 assembly in this embodiment is usually used as an external door handle. One end of the square shaft sleeve 4 relative to the handle 2 assembly is linked to the internal door handle through the square shaft. When the internal door handle is locked, a key needs to be inserted outside the door to rotate the lock cylinder 8 to unlock it. An operating shaft that is linked to the internal door handle and the locking cam 5 is usually provided in the square steel. The internal door handle can be locked or unlocked by rotating the operating shaft.

[0031] The various parts are integrated into the mounting frame 11 to form a modular assembly, thereby improving the subsequent assembly efficiency, and the stability of the various components after connection is better.

[0032] The mounting frame 11 includes a connecting sleeve 12 and a pressing plate 13. The connecting sleeve 12 is provided with a socket 14 for installing the locking mechanism 3. The lock core 8, the locking cam 5 and the square shaft sleeve 4 are inserted into the socket 14 in sequence. The lock housing 10 is sleeved outside the square shaft sleeve 4. The pressing plate 13 is fixedly connected to the connecting sleeve 12, so that the lock core 8, the locking cam 5, the square shaft sleeve 4 and the lock housing 10 are limited between the pressing plate 13 and the connecting sleeve 12. After the parts are installed into the connecting sleeve 12 one by one, they are fixed by the pressing plate 13, so that the scattered parts form a modular assembly.

[0033] The connecting sleeve 12 is provided with a plurality of connecting posts 15 and threaded holes are provided in the connecting posts 15 . The pressing plate 13 is provided with through holes corresponding to the threaded holes at positions corresponding to the connecting posts 15 . The fasteners pass through the through holes of the pressing plate 13 and are threadedly connected with the threaded holes of the connecting posts 15 .

[0034] A blank area 16 is formed between the connecting sleeve 12 and the pressure plate 13, which is located outside the insertion hole 14. The outer cover of the lock housing 10 is provided with a torsion spring 17 for driving the handle 2 to return to its original position after rotation, and the torsion spring 17 is located in the blank area 16. A flange 18 is provided outside the lock housing 10, which is located in the blank area 16, and the flange 18 abuts against the inner wall of the pressure plate 13 to prevent the lock housing 10 from detaching from the pressure plate 13 of the mounting frame 11.

[0035] like Figure 6 , 7 As shown, the arrow direction is the clockwise direction of the front face of the handle assembly, and two symmetrically arranged ears 19 are provided on the flange 18. The torsion spring 17 has a first pin 20 and a second pin 21, and the first pin 20 and the second pin 21 are respectively abutted against the corresponding side walls of the ear 19. The lock housing 10 is provided with a limiting surface 22 for driving the first pin 20 to twist, and the limiting surface 22 is opened on the side of the connecting column 15. The handle 2 is rotated clockwise so that the limiting surface 22 of the mounting frame 11 pushes the first pin 20, and the first pin 20 is separated from the ear 19 to make the torsion spring 17 generate a torsional force. When the handle 2 is rotated to a certain angle and then released, it can automatically reset.

[0036] The handle 2 includes a mounting portion 23 and a handle portion 24 that rotates relative to the lock seat 1. The mounting portion 23 is a rectangular structure. The shape of the lock seat 1 is adapted to the shape of the mounting portion 23. Locking blocks 25 are provided on both sides of the center of the inner wall of one side of the mounting cavity of the lock seat 1 along the length direction. The locking blocks 25 are located on the rotation path of the mounting portion 23. When the mounting portion 23 rotates clockwise at a certain angle, the inner wall on one side along the width direction abuts against the locking block 25, and the rotation angle range is 0-45°.

[0037] When a lock groove 29 is provided in the mounting frame 11, the mounting frame 11 has an unlocked state in which it is linked with the square shaft sleeve 4 to realize synchronous rotation, and a locked state in which the mounting frame 11 is released from the linkage with the square shaft sleeve 4 to realize its own idling and the square shaft sleeve 4 is stationary. A part of the locking ball 6 enters or leaves the lock groove 29 to realize the switching between the unlocked state and the locked state. In this way, even if the inner door handle is locked, the outer door handle can also idle. The traditional outer door handle is stationary when locked. Pressing the outer door handle multiple times may cause deformation or downward deviation.

[0038] When a lock groove 29 is provided in the lock housing 10, a part of the locking ball 6 enters or disengages from the lock groove 29 to realize the switching between the locked state and the unlocked state of the handle 2. Specifically, in the locked state, the locking ball 6 of the lower sleeve 4 enters the lock groove 29 of the lock housing 10, and the mounting frame 11 and the square sleeve 4 are stationary and cannot rotate. In the unlocked state, a part of the locking ball 6 of the lower sleeve 4 disengages from the lock groove 29 of the lock housing 10, and the mounting frame 11 can drive the square sleeve 4 to rotate synchronously to realize unlocking. The key is inserted to rotate the locking cam 5, and the locking ball 6 can move.

[0039] A groove 26 is arranged on the back of the lock base 1 and an anti-skid pad 27 is arranged in the groove 26 . The anti-skid pad 27 can be made of rubber or other anti-skid materials.

[0040] The locking cam 5 is provided with two cam surfaces 28 adapted to the locking ball 6 . The cam surfaces 28 can be used to accommodate the locking ball 6 . When the locking ball 6 contacts different positions of the cam surfaces 28 , the position will change, so that a part of the locking ball 6 enters or leaves the locking groove 29 .

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only preferred examples of the utility model, and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected, and the scope of protection of the utility model is defined by the attached claims and their equivalents.
