Description

Technical Field

[0001] This utility model relates to the field of hinges, and in particular to a detachable oil-free hinge. Background Technology

[0002] The existing hinges are mainly composed of three parts: the first hinge body on both sides, the second hinge body, and the connecting shaft. The first hinge body and the second hinge body are rotatably connected to the connecting shaft, and the connecting shaft is sealed inside by plugs at both ends.

[0003] However, the existing design requires the first and second hinge bodies to be assembled before shipping. This design is inconvenient for disassembly and assembly, and it is difficult to adjust according to the position of the connection holes on the door or door frame. Door disassembly and assembly are also inconvenient. However, if the first and second hinge bodies are not completely fixed together, the door can be removed from the door frame by lifting the door. This not only facilitates the installation and disassembly of the door, but also the installation and disassembly of the hinges. Utility Model Content

[0004] The main purpose of this utility model is to provide a detachable oil-free hinge that is not completely fixed between the first hinge body and the second hinge body, which facilitates the installation and removal of the door and the hinge.

[0005] This utility model proposes a detachable oil-free hinge, including a first hinge body, a second hinge body, and a connecting pivot.

[0006] A first hinge connecting post is provided on one side of the first hinge body. A first hinge body through hole is provided in the first hinge connecting post. A second hinge connecting post is provided on one side of the second hinge body. A second hinge body through hole is provided in the second hinge connecting post.

[0007] The two ends of the connecting shaft are respectively disposed in the through holes of the first hinge body and the second hinge body, thereby rotatably connecting the first hinge body and the second hinge body to the connecting shaft. A partition boss protruding outward is provided in the middle of the side of the connecting shaft, which separates the first hinge connecting post and the second hinge connecting post.

[0008] Preferably, the first hinge body is provided with a plurality of first hinge body connection holes, and the first hinge body can be connected and installed on the door frame through the first hinge body connection holes.

[0009] Preferably, the second hinge body is provided with a plurality of second hinge body connection holes, and the second hinge body can be connected and installed on the door through the second hinge body connection holes.

[0010] Preferably, it further includes a first connecting plug and a second connecting plug, wherein the first connecting plug is fixedly connected to the outer end of the through hole of the first hinge body, and the second connecting plug is fixedly connected to the outer end of the through hole of the second hinge body.

[0011] Preferably, the assembly further includes a first connecting bearing and a second connecting bearing. The two ends of the connecting shaft are respectively provided with a first shaft connector and a second shaft connector. The first connecting bearing and the second connecting bearing are respectively sleeved on the outside of the first shaft connector and the second shaft connector, thereby making the first hinge body and the second hinge body rotate more smoothly.

[0012] The beneficial effects of this detachable oil-free hinge are as follows:

[0013] 1. The first and second hinge bodies are not completely fixed together, which facilitates the installation and removal of the door and the hinges. This makes subsequent use and maintenance easier.

[0014] 2. By setting two oil-free bearings, the first connecting bearing and the second connecting bearing, the rotation of the first hinge body and the second hinge body can be made smoother and cleaner. Attached Figure Description

[0019] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0020] Reference Figure 1 and Figure 2 An embodiment of the removable oil-free hinge of this utility model is proposed:

[0021] A detachable oil-free hinge includes a first hinge body 1, a second hinge body 2, a connecting shaft 3, a first connecting plug 4, a second connecting plug 5, a first connecting bearing 6, and a second connecting bearing 7.

[0022] A first hinge connecting post 11 is provided on one side of the first hinge body 1. A first hinge body through hole 12 is provided inside the first hinge body connecting post 11, and a first hinge body connecting groove is provided on the inner side of the outer end of the first hinge body through hole 12. A first connecting plug 4 is connected to the first hinge body connecting groove by means of threaded connection. The first hinge body 1 is provided with four first hinge body connecting holes 13, and the first hinge body 1 can be connected to the door frame through the first hinge body connecting holes 13.

[0023] A second hinge connecting post 21 is provided on one side of the second hinge body 2. A second hinge body through hole 22 is provided inside the second hinge connecting post 21, and a second hinge body connecting groove is provided on the inner side of the outer end of the second hinge body through hole 22. The second connecting plug 5 is connected to the second hinge body connecting groove by a threaded connection. Four second hinge body connecting holes 23 are provided on the second hinge body 2, allowing the second hinge body 2 to be connected to a door through the second hinge body connecting holes 23.

[0024] The connecting shaft 3 has a first shaft connector 31 and a second shaft connector 32 at both ends. A first connecting bearing 6 and a second connecting bearing 7 are respectively fitted onto the outside of the first shaft connector 31 and the second shaft connector 32. The first shaft connector 31 and the second shaft connector 32 are respectively located within the first hinge body through hole 12 and the second hinge body through hole 22. This allows the first hinge body 1 and the second hinge body 2 to be rotatably connected to the connecting shaft 3. The first connecting bearing 6 and the second connecting bearing 7 ensure smoother rotation of the first hinge body 1 and the second hinge body 2. A protruding dividing boss 33 is provided in the middle of the side of the connecting shaft 3, separating the first hinge connecting post 11 and the second hinge connecting post 21.

[0025] In use, first connect the first hinge body 1 and the second hinge body 2 to the door frame and door respectively. Then, insert the connecting shaft 3 into the first hinge body 1. When installing the door, align the second hinge bodies 2 on the top and bottom sides of the door with the connecting shaft 3, and then insert the connecting shaft 3 into the second hinge bodies 2. This connects the door to the door frame. At this point, the first hinge body 1 and the second hinge body 2 are not completely fixed, which facilitates the installation and removal of the door and the hinges. This makes subsequent use and maintenance easier.

[0026] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the contents of the present utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present utility model.
