[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] refer to Figures 1 to 4 As shown, a door handle installation structure of the first embodiment of the present invention includes a handle 1 and a base 2, the base 2 is provided with a mounting hole 21, the handle 1 is provided with a connecting shaft 11, the connecting shaft 11 passes through the mounting hole 21 and is rotatably connected to the inner side of the base 2; the end of the connecting shaft 11 facing the inner side of the base 2 is provided with a locking boss 12 along the outer circumference, and the locking boss 12 includes a first boss 121 and a second boss 122, and the first boss 121 and the second boss 122 are symmetrically arranged along the installation direction of the handle 1; a positioning sleeve 3 is provided on the inner side of the base 2, and the inner circumference of the positioning sleeve 3 is provided with a locking boss 12 along the axial direction. The positioning boss 12 is penetrated by a matching slot 31, and the slot 31 includes a first slot 311 and a second slot 312 corresponding to the first boss 121 and the second boss 122, and the first slot 311 and the second slot 312 are symmetrically arranged up and down along the installation position of the positioning sleeve 3; the positioning boss 12 is penetrated by the slot 31 which is clearance-matched with it, and the handle 1 is clamped in the positioning sleeve 3 after rotation, so that the handle 1 and the base 2 are rotationally matched, so that the handle 1 can be rotated to realize opening and closing, and its structure is simple and stable, the assembly efficiency is high, the production cost is low, and the service life is long and the failure rate is low.

[0024] Preferably, the first boss 121 and the second boss 122 are both arc-shaped structures, the arc angle a of the first boss 121 is slightly smaller than the arc angle c of the first slot 311, and the arc angle b of the second boss 122 is slightly smaller than the arc angle d of the second slot 312, so that the connecting shaft 11 and the positioning sleeve 3 are more smoothly assembled; the arc angle a of the first boss 121 is greater than the arc angle b of the second boss 122, and the arc angle a of the first boss 121 is greater than the arc angle d of the second slot 312, and the first boss 121 is arranged at the extending arc angle of the handle 1 at the grasping end. On one side, the first slot 311 is arranged above the positioning sleeve 3, and the grasping end of the handle 1 is inserted into the positioning sleeve 3 facing upward, so that the first boss 121 is inserted into the first slot 311 and then rotated 90 degrees to be rotationally engaged with the positioning sleeve 3. When the handle 1 is opened and locked, the first boss 121 and the second boss 122 are respectively rotationally engaged with the positioning sleeve 3, and its structural strength is higher, and the force is more balanced when used. During the opening and closing rotation process, the first boss 121 of this structure cannot fall out of the second slot 312, thereby preventing the handle 1 from loosening under extreme circumstances.

[0025] Further description, the arc angle a of the first boss 121 ranges from 45 to 90 degrees, preferably from 45 to 55 degrees. In this embodiment, the arc angle a is preferably 49 degrees. The structure of the connecting shaft 11 with this size is more stable and has higher strength.

[0026] refer to Figure 5The structure of the second embodiment of the present invention is shown. The structure of this embodiment is basically the same as the principle of the first embodiment, and the difference is that: one positioning boss 12 is provided; correspondingly, one locking groove 31 is provided, preferably, it is arranged above the positioning sleeve 3.

[0027] The structure of the third embodiment of the present invention (not shown in the figure) is as follows: Figures 1 to 5 As shown, the structure of this embodiment is basically the same as the principle of the first embodiment, the difference being that three locking bosses 12 are evenly distributed along the outer circumference of the connecting shaft 11 ; correspondingly, three locking grooves 31 are also provided in a one-to-one correspondence with the locking bosses 12 .

[0028] According to the above three embodiments of the present invention, specifically, a mounting groove 32 engaged with the mounting hole 21 is provided on the outer periphery of the positioning sleeve 3, and a bayonet 22 for the positioning boss 12 to pass through is provided at the matching position between the base 2 and the bayonet slot 31. The inner side of the bayonet 22 is arc-shaped and smoothly transitions with the surface of the bayonet slot 31, so that the connecting shaft 11 can be smoothly inserted.
