Description

Technical Field

[0001] The utility model relates to the technical field of door handles, and more particularly to a fixing structure of a handle head and a handle arm of a door handle. Background Art

[0002] A door handle is a device installed on a door and consists of a handle arm and a handle head. It is used to open or close the door.

[0003] In the prior art, the handle arm and the handle head are generally installed as a whole or in an assembled manner. In the assembled manner, holes are drilled in the outer walls of the handle arm and the handle head, and screws are screwed into the holes to connect the handle arm and the handle head together. This requires multiple screw holes to be opened in a ring to fit the screws for fixing, which is not only unsightly but also difficult to manufacture and assemble. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the present invention is to provide a fixing structure that does not require drilling holes on the outer walls of the handle head and the handle arm, and is fixed with screws.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions.

[0006] A door handle head and handle arm fixing structure includes a handle arm and a handle head, wherein the handle head is provided with a sleeve hole which is sleeved on the handle arm, a mounting hole is provided at one end of the handle arm close to the handle head, and a through hole which is connected to the mounting hole is provided on the outer wall, and an abutment is movably embedded in the through hole; a fixing part is embedded in the mounting hole, and the outer wall of the fixing part squeezes the abutment part so that the abutment part abuts against the inner wall of the sleeve hole to fix the handle head.

[0007] Preferably, a plurality of circumferential stripes are provided on the outer wall of the handle arm, and a plurality of circumferential grooves that fit with the stripes are provided on the inner wall of the sleeve hole.

[0008] Preferably, the mounting hole is a threaded hole, and the fixing member is a screw.

[0009] Preferably, the diameter of the abutment member is smaller than the diameter of the through hole and larger than the length of the through hole.

[0010] Preferably, the abutment member is a steel ball.

[0011] Preferably, the fixing member is completely embedded in the mounting hole, and a handle decorative cap covering the mounting hole is installed at one end of the handle arm close to the handle head.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] During installation, the fixing piece is embedded in the installation hole to squeeze the abutment piece, so that the abutment piece is pressed against the inner wall of the sleeve hole to fix the handle head. In this way, there is no need to open multiple threaded holes on the outer wall of the handle arm and the handle head, which is more beautiful and quick to assemble.

[0020] 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 embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0021] A fixing structure of a handle head 1 and a handle arm 2 of a door handle, comprising a handle arm 2 and a handle head 1, wherein the handle head 1 is provided with a sleeve hole 11 which is sleeved on the handle arm, a mounting hole 21 is provided at one end of the handle arm 2 close to the handle head 1, and a through hole 22 which is connected to the mounting hole 21 is provided on the outer wall, and an abutment member 3 is movably embedded in the through hole 22; a fixing member 4 is embedded and matched in the mounting hole 21, and the outer wall of the fixing member 4 squeezes the abutment member 3 so that the abutment member 3 abuts against the inner wall of the sleeve hole 11 to fix the handle head 1. It can be understood that the embedded structure of the mounting hole 21 and the fixing member 4 can be a matching structure of a threaded hole and a screw, or an interference fit of an axial hole, or a rivet embedded fit, etc., but is not limited thereto. The abutment member 3 is a component that can move in the through hole 22 and abut against the inner wall of the sleeve hole 11, and can be, for example, spherical or cylindrical, etc., but is not limited thereto. In this way, during installation, the handle head 1 is put on the handle arm 2. Here, it is necessary to ensure that the sleeve hole 11 on the handle head 1 corresponds to the through hole 22, and then the fixing part 4 is embedded in the installation hole 21, so that the abutment part 3 is squeezed by the fixing part 4 and pressed against the inner wall of the sleeve hole 11, thereby completing the fixation of the handle head 1.

[0022] In some embodiments, the outer wall of the handle arm 2 is provided with a plurality of circumferential stripes 23, and the inner wall of the sleeve hole 11 is provided with a plurality of circumferential grooves 12 that mate with the stripes 23. Thus, when the handle head 1 is placed on the handle arm 2, the stripes 23 on the outer wall of the handle arm 2 will fit into the grooves 12 on the inner wall of the sleeve hole 11, thereby locking the handle head 2 horizontally, that is, preventing the handle head 1 from rotating on the handle arm 2. When the abutment member 3 abuts against the grooves 12, the handle head 1 is completely locked.

[0023] In some embodiments, the abutment member 3 is a steel ball. Furthermore, the diameter of the abutment member 3 is smaller than the diameter of the through hole 22 and larger than the length of the through hole 22. It is understood that the steel ball is spherical, and the diameter of the abutment member 3 is smaller than the diameter of the through hole 22 to ensure that the steel ball can move in the through hole 22. The diameter of the abutment member 3 is larger than the length of the through hole 22 to ensure that the steel ball has sufficient length when squeezed by the fixing member 4, thereby abutting the inner wall of the sleeve hole 11.

[0024] In some embodiments, the fixing member 4 is completely embedded in the mounting hole 21. A handle cap 5 is installed on the end of the handle arm 2 near the handle head 1 to cover the mounting hole 21. It is understood that the handle cap 5 can be threaded or embedded in the mounting hole 21 using an elastic colloid material, but is not limited to these. In this way, the mounting hole 21 is shielded by the handle cap 5, providing both dust and water protection and a more aesthetically pleasing appearance.

[0025] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed in the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
