Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically a hook-type hinge. Background Technology

[0002] Hinges are essential hardware components that connect rotating parts such as doors, windows, and cabinets, and are widely used in construction, furniture, and industrial equipment. Traditional hinges are usually fixed with screws, making installation and disassembly cumbersome and difficult to adjust quickly. This is especially true in scenarios requiring frequent maintenance or replacement (such as large doors and windows, and server racks), where the traditional structure has significant limitations.

[0003] Current contracts all involve assembly and fixing with screws, which leads to the problem that traditional hinges require repeated tightening and loosening of screws for disassembly, resulting in high tool dependence and maintenance costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a hook-type hinge, which solves the problems of traditional hinges requiring repeated tightening / untilting of screws, high tool dependence, and high maintenance costs.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a hook-type hinge, comprising a base plate, a mounting base and blades, wherein an outer cover is fixedly mounted on the surface of the mounting base, and a locking component is provided in the inner cavity of the mounting base;

[0006] The locking assembly includes a sleeve plate fixedly connected to the inner wall of the mounting base, and the inner cavity of the sleeve plate is symmetrically fitted with insert plates via springs.

[0007] The blade has an integrally extended buckle at its bottom, and the buckle has symmetrically formed slots on its surface.

[0008] A baffle is fixedly installed in the inner cavity of the substrate by screws;

[0009] The buckle passes through the inner cavity of the substrate and extends into the inner cavity of the mounting base, pressing the insert plate, which engages with the slot.

[0010] Preferably, the buckle fits into the inner cavity of the mounting base, and one end of the blade is rotatably connected to a connecting plate via a rotating shaft.

[0011] Preferably, an eccentric shaft and a bolt are symmetrically arranged on the surface of the substrate, and a limit block is threaded onto the surface of the bolt.

[0012] Preferably, the surface of the substrate is fixedly connected to the mounting base by connecting bolts, and the limiting block is located in the sliding groove at the bottom of the mounting base, and the bolt passes through the vertical U-shaped groove at the top of the mounting base.

[0013] Preferably, one end of the eccentric shaft extends into the transverse U-shaped groove at the top of the mounting base.

[0014] Preferably, one end of the screw extends into the inner cavity at the top of the mounting base.

[0015] This utility model provides a hook-type hinge. Compared with the prior art, it has the following advantages:

[0016] 1. This hook-type hinge passes through the middle of the base plate through a snap and enters the inner cavity of the mounting base by fitting against the baffle. At the same time, it will squeeze the insert plate, causing the insert plate to slide in the inner cavity of the sleeve plate. Meanwhile, the spring will be compressed, and finally the insert plate will be located in the slot. Under the elastic force of the spring, the insert plate will be snapped into the slot to complete the engagement, and then the blade will be fixed, which facilitates the assembly and disassembly of the hinge itself.

[0017] 2. This hook-type hinge, by rotating the eccentric shaft, pushes the mounting base to move left and right through the transverse U-shaped groove, without affecting the bolts, thus achieving position adjustment. Also, by rotating the connecting bolts, the limiting block moves simultaneously with the mounting base due to the limiting block being restricted, thereby adjusting the distance between the base plate and the mounting base.

[0024] 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.

[0025] Please see Figures 1-5 This utility model provides a technical solution: a hook-type hinge, including a base plate 1, a mounting base 2, and a blade 3. An outer cover 21 is fixedly installed on the surface of the mounting base 2, wherein the outer cover 21 facilitates observation of the inner cavity of the mounting base 2, and a locking component 22 is provided in the inner cavity of the mounting base 2. A buckle 32 extends integrally from the bottom of the blade 3, and slots 34 are symmetrically opened on the surface of the buckle 32. The buckle 32 fits into the inner cavity of the mounting base 2, so that the buckle 32 does not wobble when it enters the inner cavity of the mounting base 2. One end of the blade 3 is rotatably connected to a connecting plate 31 through a rotating shaft 33. The connecting plate 31 and the base plate 1 can be connected to the door and the door frame respectively.

[0026] An eccentric shaft 11 and a bolt 13 are symmetrically arranged on the surface of the substrate 1. A limit block 12 is threaded onto the surface of the bolt 13. The surface of the substrate 1 is fixedly connected to the mounting base 2 by a connecting bolt 16, and the limit block 12 is located in a groove at the bottom of the mounting base 2. The bolt 13 passes through a vertical U-shaped groove at the top of the mounting base 2. One end of the eccentric shaft 11 extends into a horizontal U-shaped groove at the top of the mounting base 2, and one end of the screw 15 extends into the inner cavity at the top of the mounting base 2. The limit block 12 is first slidably fitted onto the bottom of the mounting base 2. The substrate 1 and the mounting base 2 are connected by screwing the bolt 13 into the groove of the part and screwing the bolt 13 into the limiting block 12. Then the eccentric shaft 11 will enter the transverse U-shaped groove. Then the eccentric shaft 11 will be rotated. The mounting base 2 will be adjusted left and right by the eccentric movement of the eccentric shaft 11. After the position is determined, the connecting bolt 16 will be installed to install the substrate 1 and the mounting base 2. The distance between the substrate 1 and the mounting base 2 can be adjusted by the connecting bolt 16. Finally, the bolt 13 will be tightened to complete the fastening of the substrate 1 and the mounting base 2.

[0027] The locking assembly 22 includes a sleeve plate 221 fixedly connected to the inner wall of the mounting base 2. The inner cavity of the sleeve plate 221 is symmetrically fitted with an insert plate 222 via a spring 223. The elasticity of the spring 223 causes the insert plate 222 to slide within the inner cavity of the sleeve plate 221. The buckle 32 passes through the inner cavity of the base plate 1 and extends into the inner cavity of the mounting base 2, pressing the insert plate 222. The insert plate 222 engages with the slot 34, allowing the insert plate 222 to be inserted into the slot 34 for engagement. Both the buckle 32 and the insert plate 222 are inclined to facilitate the buckle 32 pressing the insert plate 222. A baffle 14 is fixedly installed in the inner cavity of the base plate 1 via a screw 15. The baffle 14 is used to abut against the side of the buckle 32. Thus, the buckle 32 is engaged in the mounting base 2 through the engagement of the insert plate 222 and the abutment of the baffle 14.

[0028] During operation or use, first, attach the substrate 1 and the mounting base 2 together. Then, slide the limiting block 12 into the groove at the bottom of the mounting base 2. Next, insert the bolt 13 from the surface of the substrate 1, so that the bolt 13 passes through the vertical U-shaped groove and is threaded into the limiting block 12, thus completing the connection between the substrate 1 and the mounting base 2. There is a gap between the bolt 13 and the mounting base 2. Then, the eccentric shaft 11 will enter the horizontal U-shaped groove. Therefore, rotating the eccentric shaft 11 will push the mounting base 2 to move left and right in the horizontal U-shaped groove without affecting the bolt 13, thus achieving position adjustment. After determining the position, install the connecting bolt 16 and screw the connecting bolt 16 into the groove. The blade 3 rotates into the mounting base 2, and as the connecting bolt 16 rotates, the distance between the mounting base 2 and the base plate 1 can be adjusted. Then, the baffle 14 is installed on the inner wall of the base plate 1 by screw 15. Finally, the buckle 32 at one end of the blade 3 passes through the middle of the base plate 1 and fits against the baffle 14 into the inner cavity of the mounting base 2. At the same time, it will squeeze the insert plate 222, causing the insert plate 222 to slide in the inner cavity of the sleeve plate 221. At the same time, the spring 223 will be compressed, and finally the insert plate 222 will be located in the slot 34. Under the elastic force of the spring 223, the insert plate 222 will be snapped into the slot 34 to complete the snap-fit. Then the blade 3 is fixed. Finally, the outer cover 21 is fixedly installed.

[0029] During disassembly, remove the baffle 14 so that there is no longer any obstruction on one side of the buckle 32. Then slide the buckle 32 to one side so that the insert plate 222 leaves the slot 34. Then the buckle 32 can be directly removed from the mounting base 2. Therefore, the locking component 22 and the fastening of 4 facilitate disassembly and assembly.

[0030] When the connecting bolt 16 is rotated, the limiting block 12 is limited and moves simultaneously with the mounting base 2, thereby driving the bolt 13 to move on the surface of the eccentric shaft 11. When the gap between the base plate 1 and the mounting base 2 is determined, the bolt 13 is rotated again to lock the bolt 13 in the limiting block 12, thus securing the base plate 1 and the mounting base 2.
