For example, the hinge is not flexible to rotate after being loaded, and a lot of effort is required to open and close it. At the same time, the hinge is prone to friction noise due to hard friction during use. In addition, the entire hinge is prone to locking after being used for a period of time.

[0005] In view of the problems in the above-mentioned background technology, the utility model aims to provide a planar booster hinge. Utility Model Content

[0010] Both ends of the arranged pin pass through the pin hole opened at one end of the out-of-plane hinge and the pin hole opened at one end of the in-plane hinge at the same time, and the thrust bearing assembly is sleeved on the outside of the pin and one side is movably installed inside the pin hole opened on the out-of-plane hinge.

[0011] As a further solution of the utility model: the outer hinge surface of the plane is symmetrically provided with mounting holes, and the inner hinge surface of the plane is symmetrically provided with mounting holes.

[0012] As a further solution of the utility model: the thrust bearing assembly includes a bearing seat, balls and a bearing cover, an axial hole is opened in the middle of the bearing seat; an annular groove is formed between the outer side of the bearing seat and the inner side of the bearing cover, and balls are arranged and distributed in intervals inside the annular groove.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] Compared with the existing hinges, the planar booster hinge has the following advantages:

[0015] First, the thrust bearing assembly structure is added to the original hinge structure. The thrust bearing assembly includes a bearing seat, a ball and a bearing cover. After the fully enclosed thrust bearing is added to the entire plane thrust hinge, it can be opened and closed smoothly with less force under high load conditions. At the same time, after multiple heavy load tests, there is no wear and friction sound, and there will be no locking phenomenon after regular refueling.

[0016] 2. Install the flat booster hinge on the door frame and the door. The sliding property of the ball bearing can be used to open and close the door with less effort. This avoids the disadvantages of the original hard friction opening and closing and maximizes the service life of the door. BRIEF DESCRIPTION OF THE DRAWINGS
