[0035] Referring to the door handle of the present application, it comprises a handle 2 and a mounting base 1, the mounting base 1 is provided with a through sleeve 3, the handle 2 is provided with a sleeve cavity 4 at the back, the sleeve cavity 4 is provided with a rotating shaft 5, the handle 2 is sleeved into the sleeve 3 through the sleeve cavity 4, the rotating shaft 5 is inserted into the sleeve 3 to realize the rotating connection between the handle 2 and the mounting base 1, the elastic retracting mechanism and the limiting structure matched with the elastic retracting mechanism are arranged on the rotating shaft 5 and the inner side wall of the sleeve 3 respectively, and are arranged in the sleeve cavity 4 together with the rotating shaft 5 and the sleeve 3 to form a nested assembly relationship, which can simplify the structure of the mounting base 1 to reduce the height, and the nested structure can also greatly reduce the installation height between the handle 2 and the mounting base 1, thereby achieving the purpose of reducing the overall height of the handle. Moreover, the handle 2 body does not need to be designed too much due to the absence of the elastic retracting mechanism, so that the structure of the handle 2 can be simplified, and the elastic retracting mechanism is arranged on the rotating shaft 5 as the core component of the rotating connection, which can more calmly cope with the modification according to customer requirements. For example, if it is required to provide a larger torque for the handle to obtain clearer positioning and stronger hand feeling, the rotating torque can be increased by increasing the contact and cooperation between the elastic retracting mechanism and the limiting structure in the circumferential direction.

[0036] In the embodiments disclosed by the present application, the limiting structure comprises two or more limiting grooves 6 distributed around the inner side wall of the sleeve 3, the elastic retracting mechanism is provided with elastic members 7 which can be elastically stretched and retracted, and the number of the elastic members 7 can be increased according to requirements. For example, the elastic members 7 are symmetrically arranged at two positions, which can uniformly apply force and better bear stress. The elastic members 7 cooperate with the limiting grooves 6 to limit the rotation of the handle 2, and the rotation positioning of the handle 2 is realized through the concave-convex cooperation, so that the user can clearly know that the handle 2 has been rotated to the position and the unlocking or locking is realized. When the handle 2 is in the unlocking or locking state, the two elastic members 7 cooperate with the two limiting grooves 6 to provide a larger torque for the handle 2, so that the handle 2 cannot be easily rotated due to gravity or slight touch and lose the current state, which is more conducive to the next operation of the user. As shown in FIG. 3 or FIG. 8, the limiting grooves 6 are four and are uniformly distributed around the inner side wall of the sleeve 3, so that the handle 2 can trigger the cooperation between the elastic retracting mechanism and the limiting structure when it is rotated to the left or right, which makes the installation adaptability of the present application higher. Further, on the basis of the four limiting grooves 6, small grooves (not shown in the figure) can be continuously increased between each limiting groove 6, but the depth of the small grooves is shallower than that of the limiting grooves 6. When the elastic members 7 pass through these small grooves, the user can have a good operation feeling. The elastic members 7 can adopt two implementation modes of elastic balls or elastic sheets, and the present application preferably adopts the elastic ball scheme. The elastic balls can roll out of the limiting grooves 6, so that the operation of the user is more labor-saving.

[0037] The rotating shaft 5 and the sleeve cavity 4 can be arranged in an integrated or split disassembly scheme:

[0038] As shown in the first embodiment of FIG. 2 to FIG. 4, the rotating shaft 5 is integrally arranged in the sleeve cavity 4, at this time, the rotating shaft 5 comprises a transmission hole 52 for inserting the transmission shaft 8, one end of the transmission shaft 8 is provided with a retracting mechanism and penetrates into the transmission hole 52 to realize the arrangement of the retracting mechanism on the rotating shaft 5, the side wall of the transmission hole 52 is provided with an avoiding slot 53 for the retracting mechanism to penetrate out and cooperate with the limiting structure, the arrangement of the retracting mechanism by the transmission shaft 8 can make the arrangement structure of the retracting mechanism more simplified, and is more conducive to the assembly arrangement of the retracting mechanism; and the other end of the transmission shaft 8 is connected with the lock body in the window door, and the lock body in the window door can be driven to work by rotating the handle 2 to realize the locking or unlocking of the window door.

[0039] As a preferred scheme of the first embodiment, the bottom end side wall of the rotating shaft 5 is provided with a snap spring slot 59 and penetrates out from the bottom of the sleeve 3, the snap spring slot 59 is snapped into the snap spring 91 and makes the bottom end of the rotating shaft 5 snap set at the bottom of the sleeve 3 by the snap spring 91, so that the handle 2 can be fixed relative to the axial direction of the sleeve 3.

[0040] As shown in the second embodiment of FIG. 5 to FIG. 8, the rotating shaft 5 is modified to be detachable and separated structure relative to the sleeve cavity 4 based on the first embodiment, at this time, the rotating shaft 5 has the transmission hole 52 and the avoiding slot 53 and is detachably installed with the sleeve cavity, the top of the rotating shaft 5 is provided with a mounting hole 54, the top wall of the sleeve cavity 4 is provided with a threaded hole 41 corresponding to the mounting hole 54, the rotating shaft 5 penetrates through the sleeve 3 and is installed in the sleeve cavity 4, the screw 92 is installed in the transmission hole 52, penetrates through the mounting hole 54 and is connected with the threaded hole 41 to fix the rotating shaft 5 in the sleeve cavity 4, and the bottom end of the rotating shaft 5 is provided with a bending part 51, the rotating shaft 5 penetrates through the bottom opening of the sleeve 3 in sequence, is bent outward by the bending part 51 and abuts against the bottom of the sleeve 3, and the gasket is clamped between the bending part 51 and the bottom of the sleeve 3, so that the handle 2 can be fixed relative to the axial direction of the sleeve 3, and the assembly of the handle 2 and the mounting base 1 is realized, and the assembly connection between the handle 2 and the mounting base 1 becomes more convenient. And the small part module is processed and assembled by the detachable rotating shaft 5, so that the processing procedure can be more simple and conducive to the processing and production of the handle 2.

[0041] As a preferred solution of the second embodiment, the top of the rotating shaft 5 is provided with a limiting table 55, and the top wall of the sleeve cavity 4 is provided with a limiting groove 42 for embedding the limiting table 55. The circumferential shape of the limiting table 55 can be square or oval, etc. The axial shape of the inner side wall of the sleeve cavity 4 matches the limiting table 55. When the limiting table 55 is embedded in the limiting groove 42, the rotating shaft 5 and the sleeve cavity 4 are relatively circumferentially positioned and cannot rotate. The mounting hole 54 penetrates the limiting table 55, and the threaded hole 41 is arranged in the limiting groove 42. When the rotating shaft 5 is connected and fixed with the sleeve cavity 4 by penetrating the mounting hole 54 and the threaded hole 41 through the screw 92, the limiting table 55 is also embedded in the limiting groove 42 to realize circumferential positioning, so that the handle 2 can more stably drive the rotating shaft 5, and better drive the transmission shaft 8 and the retracting mechanism to work.

[0042] As shown in FIGS. 9-13, the third embodiment also adopts the detachable separation scheme of the rotating shaft 5 and the sleeve cavity 4, but is different from the first and second embodiments in that the rotating shaft 5 directly integrates the retracting mechanism in the rotating shaft 5 by arranging a mounting cavity 56, thereby constituting a modular connecting component, which is more convenient for realizing the rotating installation of the handle 2. The side wall of the mounting cavity 56 is provided with an avoiding hole 57 for the retracting mechanism to pass out and cooperate with the limiting structure.

[0043] Since the retracting mechanism is directly arranged in the rotating shaft 5, the way of locking the window door by the handle and the arrangement of the mechanism become more flexible. For example, a simple latch handle that latches the window frame or door frame by a latch (as shown in FIG. 15), on the basis of the third embodiment, directly increases the latch 21 on the handle 2, which can be moved by the rotation of the handle 2 to latch the window frame to lock or leave the window frame to unlock, thereby realizing the arrangement of the latch handle.

[0044] Of course, the third embodiment is preferably a transmission handle scheme that adopts a transmission shaft and a transmission connection with an inner lock body of the window door. Only the bottom of the mounting cavity 56 needs to be changed into a transmission hole for transmission plug-in with the transmission shaft.

Further, the top of the rotating shaft 5 is provided with a limiting platform 55, the top wall of the sleeve cavity 4 is provided with a limiting recess 42 for embedding the limiting platform 55, the limiting platform 55 is embedded in the limiting recess 42 to relatively position the rotating shaft 5 and the sleeve cavity 4 in the circumferential direction; the limiting hole 58 is located at the side of the limiting platform 55, that is, when the rotating shaft 5 is fixed in the sleeve cavity 4 by the fastening screw 93, the limiting platform 55 is also embedded in the limiting recess 42 to realize the circumferential positioning, so that the rotating shaft 5 can be more stably driven by the handle 2 and better drive the retracting mechanism to work.

[0046] As the fourth embodiment of the present application, as shown in FIG. 14, the rotating shaft 5 with the mounting cavity 56 is integrally arranged in the sleeve cavity 4 based on the third embodiment, and the retracting mechanism is arranged in the mounting cavity 56.
