[0014] 1. When the hinge is in use, the upper and lower parts of the hinge can be connected by inserting the positioning shaft into the first and second hinge shafts. When the upper part of the hinge rotates, the hexagonal block is engaged in the hexagonal hole to prevent the positioning shaft from rotating when the upper part of the hinge rotates. At this time, the positioning sleeves, the positioning grooves and positioning blocks on the side surface can enhance the friction of the positioning shaft in the hinge hole, thus improving the positioning effect of the upper part of the hinge. Compared with the hinge structure in the prior art "a hinge with positioning function", this utility model can significantly improve the positioning effect of the hinge and improve the ease of use through the cooperation of the above structures.

[0015] 2. When using the hinge, firstly, the two telescopic shafts are controlled to extend and retract, supporting the inner wall of the structure. This, along with the connecting block and stabilizing plate, initially improves the stability of the lower part of the hinge. Then, the second bolt is controlled to rise and fall along the second screw hole. The suction cup bottom and the inner wall of the structure adhere to each other, further improving the overall structural stability of the hinge assembly. When the lower part of the hinge is subjected to force and the lifting rod descends, the lifting rod discharges the air in the air storage tube from the air outlet, thus providing a buffering and protective effect. Compared with the hinge in the existing technology "a hinge with positioning function", this utility model, through the cooperation of the above structures, can significantly improve the installation stability and protective strength of the hinge, thereby enhancing its practicality.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 This utility model provides a hinge with rotation positioning function, including a hinge assembly 100, a support assembly 200, a stabilizing assembly 300 and a buffer assembly 400.

[0025] The hinge assembly 100 includes an upper hinge 101, with a first hinge shaft 102 fixedly connected to the upper end of the upper hinge 101. One end of the first hinge shaft 102 has a hinge hole 103. The upper end of the upper hinge 101 is hinged to a lower hinge 104. The upper end of the lower hinge 104 is fixedly connected to two second hinge shafts 105. One end of each second hinge shaft 105 has a hexagonal hole 106. A hexagonal block 107 is engaged inside the hexagonal hole 106. One end of the hexagonal block 107 is fixedly connected to a positioning shaft 108. A plurality of positioning sleeves 109 are fitted on the side surface of the positioning shaft 108. Each of the positioning sleeves 109 has a positioning groove 110 on its side surface. A positioning block 120 is fixedly connected to the side surface of the positioning sleeves 109. The positioning shaft 108 and the plurality of positioning sleeves 109 on its side surface are inserted into the hinge hole 103.

[0026] The top support assembly 200 includes two telescopic shafts 201 installed at the front end of the lower hinge 104. The front ends of the two telescopic shafts 201 are rotatably connected to a connecting block 202. The front ends of the telescopic shafts 201 are fixedly connected to a universal ball 203. A spherical groove 204 is opened on the surface of the connecting block 202. The universal ball 203 is rotatably connected inside the spherical groove 204. A stabilizing plate 205 is detachably installed on the surface of the connecting block 202.

[0027] Stabilizing components 300 and buffering components 400 are respectively installed on both sides and at the bottom of the lower part 104 of the hinge.

[0028] In one specific embodiment, the hinge assembly 100, in conjunction with the support assembly 200, the stabilizing assembly 300, and the buffer assembly 400, not only significantly improves the positioning effect after hinge angle adjustment, thereby enhancing ease of use, but also facilitates improved installation stability and protection of the hinge through the cooperation of the above structures, thus enhancing the practicality of the hinge. In use, the two telescopic shafts 201 are first controlled to extend and retract, and the connecting block 202 and its end stabilizing plate 205 provide support to the inner wall of the structure, thus initially improving stability. When the upper part 101 of the hinge rotates, the hexagonal block 107 inserted into the hexagonal hole 106 can prevent the upper part 101 of the hinge from rotating with the positioning shaft 108. Subsequently, several positioning sleeves 109 on the side surface of the positioning shaft 108, in conjunction with the positioning groove 110 and the positioning block 120 on the side surface, can significantly improve the positioning effect of the hinge, thereby significantly enhancing the ease of use and practicality of the hinge.

[0029] Please see Figures 2-4 The front end of the lower hinge 104 is fixedly connected by two first bolts 111.

[0030] In one specific embodiment, the first bolt 111 can improve the connection strength and ease of assembly and disassembly between the lower hinge 104 and the telescopic shaft 201.

[0031] Please see Figure 5 One end of the telescopic shaft 201 is provided with a first screw hole 211, and a first bolt 111 is threaded into the inside of the first screw hole 211. A collar 212 is fixedly connected to the surface of the stabilizing plate 205 and is sleeved on the side surface of the connecting block 202.

[0032] In one specific embodiment, the threaded connection of the first bolt 111 inside the first screw hole 211 can enhance the installation and fastening of the telescopic shaft 201.

[0033] Please see Figures 2-4 The stabilizing component 300 includes ear blocks 301 installed on both sides of the lower part 104 of the hinge. The surface of the ear block 301 is provided with a second screw hole 302. The inner thread of the second screw hole 302 is connected to a second bolt 303. The lower end of the second bolt 303 is fixedly connected to a suction cup 304.

[0034] In one specific embodiment, by threading the second bolt 303 into the second screw hole 302, and then controlling the second bolt 303 to move up and down along the second screw hole 302 so that the suction cup 304 and the bottom of the structure can adhere to each other, the installation stability of the lower part of the hinge 104 can be further improved.

[0035] Please see Figure 6The buffer assembly 400 includes an air storage pipe 401, a lifting rod 402 is inserted into the air storage pipe 401, and an air outlet 403 is opened on one side of the air storage pipe 401.

[0036] In one specific embodiment, when the lower part 104 of the hinge is subjected to force and the lifting rod 402 is raised or lowered, the lowering of the lifting rod 402 will squeeze the air in the air storage pipe 401 out of the air outlet 403, which can play a buffering role and further improve the protection effect on the hinge.

[0037] Please see Figures 2-4 The suction cup 304 is made of silicone.

[0038] In one specific embodiment, the silicone suction cup 304 has a flexible structure that can prevent bumps and knocks on the lower part 104 of the hinge.

[0039] Working principle: In use, firstly, the two telescopic shafts 201 are controlled to extend and retract. With the help of the connecting block 202 and its end stabilizing plate 205, the inner wall of the structure is supported, which can initially improve the stability. When the upper part of the hinge 101 rotates, the hexagonal block 107 is inserted into the hexagonal hole 106 to prevent the upper part of the hinge 101 from rotating with the positioning shaft 108. Then, through the several positioning sleeves 109 on the side surface of the positioning shaft 108, the positioning groove 110 and positioning block 120 on the side surface can significantly improve the positioning effect of the hinge, thereby significantly enhancing the ease of use and practicality of the hinge.
