Description

Technical Field

[0001] This utility model relates to the field of bearing hinge technology, specifically to a high-strength load-bearing bearing hinge for passive doors. Background Technology

[0002] A hinge, also known as a hinge plate, is a mechanical device used to connect two solid objects and allow them to rotate relative to each other. It typically consists of two hinge plates and a hinge pin. The two hinge plates are fixed to the two objects to be connected, and they are connected by the hinge pin, allowing the objects to rotate about the axis of the hinge pin.

[0003] When installing a passive door, hinges are usually used to install it, allowing the passive door to open and close freely. However, most existing hinges have a relatively simple structure, consisting of a hinge plate and a hinge pin. Since the passive door is installed on the exterior wall by the hinge, if the passive door is heavy, the hinge may not be able to support the weight of the passive door after repeated use, resulting in damage. Therefore, a high-strength load-bearing bearing hinge specifically for passive doors is proposed. Utility Model Content

[0004] This utility model proposes a high-strength load-bearing bearing hinge specifically for passive doors, which solves the problem in related technologies where hinges with poor load-bearing capacity are prone to detaching from the wall when supporting heavy passive doors.

[0005] The technical solution of this utility model is as follows:

[0006] A high-strength load-bearing bearing hinge for passive doors includes a first hinge, a bushing, a load-bearing component, a round bar, a second hinge, and a support component. The first hinge is threadedly connected to the wall with bolts. Two bushings are provided, each fixedly installed on the side of the first hinge. Two load-bearing components are provided, each mounted on one of the two bushings. The round bar is mounted on one of the two load-bearing components. The second hinge is fixedly installed on the side of the round bar. Two support components are provided, each mounted on the side of the first hinge.

[0007] Furthermore, the load-bearing component includes connecting rods, bearings, and metal washers. There are two connecting rods, which are fixedly installed on the inner side wall of the bushing. The bearings are fixedly installed between the two connecting rods, and the two ends of the round bar are respectively fixedly installed on the two bearings. There are two metal washers, which are respectively fixedly installed on the two ends of the round bar.

[0008] Furthermore, the support assembly includes support blocks and support rods. Two support blocks are provided, and the two support blocks are respectively fixedly installed on the sides of the two bushings. Two support rods are provided, and the two support rods are both fixedly installed on the side of the first hinge.

[0009] Furthermore, the upper end of the round bar is provided with three stepped discs whose diameter gradually increases from the top to the bottom, and one of the bearings is fixedly installed through the top of the round bar.

[0010] Furthermore, the lower end of the round bar is provided with three stepped discs whose diameter gradually increases from the lower end upwards, and another bearing is fixedly installed through the bottom end of the round bar.

[0011] Furthermore, a head groove is formed at the bottom end of the support block, the side of the support rod is fixedly installed on the side of the hinge, and the top end of the support rod fits into the groove at the bottom end of the support block.

[0012] Furthermore, the bearing includes an outer ring, an inner ring, and balls. The inner rings of the two bearings are respectively fixedly installed at the top and bottom ends of the round bar, and the connecting rod is fixedly installed between the outer ring of the bearing and the inner sidewall of the bushing.

[0013] Furthermore, the bearing, the metal washer, and the connecting rod are all located inside the bushing.

[0014] Furthermore, the round bar is made of a high-strength metal material.

[0015] Furthermore, the stepped disks at the top and bottom of the round bar are located within the two bushings, respectively.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] 1. In this utility model, during use, the bearing can drive the round bar to rotate, thereby driving the second hinge and the passive door to rotate. The bearing can both drive the round bar to rotate and support the round bar and the second hinge. The bearing has good bearing capacity, and the round bar is made of high-strength metal material, so it has good load-bearing capacity.

[0018] 2. In this utility model, the support rod can support the support plate during installation, thereby supporting the bushing and the second hinge, so that when the second hinge is connected to the passive door, it has an upward supporting force to prevent breakage;

[0019] In summary, through the cooperation of hinge one, bushing, load-bearing component, round bar, hinge two, and support component, the hinge can have a strong load-bearing capacity, thereby supporting the passive door and preventing the hinge from detaching from the wall due to poor load-bearing capacity or from detaching from the hinge due to the weight of the passive door.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0027] like Figures 1-4 As shown, this embodiment proposes a high-strength load-bearing bearing hinge specifically for passive doors, including hinge 1, bushing 2, load-bearing components, round bar 3, hinge 2, and support components. Hinge 1 is connected to the wall by bolts and threads. There are two bushings 2, which are respectively fixedly installed on the side of hinge 1. There are two load-bearing components, which are respectively installed on the two bushings 2. The round bar 3 is installed on the two load-bearing components. Hinge 2 is fixedly installed on the side of the round bar 3. There are two support components, which are both installed on the side of hinge 1.

[0028] Round bar 3 is a high-strength metal material, and high-strength metal materials have strong load-bearing capacity.

[0029] In this embodiment, the load-bearing component includes a connecting rod 101, a bearing 102, and a metal washer 103. There are two connecting rods 101, which are fixedly installed on the inner side wall of the bushing 2. The bearing 102 is fixedly installed between the two connecting rods 101, and the two ends of the round bar 3 are respectively fixedly installed on the two bearings 102. There are two metal washers 103, which are respectively fixedly installed on the two ends of the round bar 3.

[0030] In this embodiment, the support assembly includes a support block 201 and a support rod 202. There are two support blocks 201, which are fixedly installed on the sides of the two bushings 2 respectively. There are two support rods 202, which are fixedly installed on the sides of the hinge 1.

[0031] The upper end of the round bar 3 is provided with three stepped discs whose diameter increases progressively from the top to the bottom, and one of the bearings 102 is fixedly installed through the top of the round bar 3. The lower end of the round bar 3 is provided with three stepped discs whose diameter increases progressively from the bottom to the top, and another bearing 102 is fixedly installed through the bottom of the round bar 3.

[0032] The bottom end of the support block 201 has a head groove. The side of the support rod 202 is fixedly installed on the side of the hinge 1, and the top end of the support rod 202 fits into the groove at the bottom end of the support block 201. The support rod 202 is fixedly connected to the hinge 1, and the hinge 1 is connected to the wall, so that the support rod 202 supports the support plate and then supports the round rod 3.

[0033] Furthermore, the bearing 102 includes an outer ring 301, an inner ring 302, and balls 303. The inner rings 302 of the two bearings 102 are respectively fixedly installed at the top and bottom ends of the round bar 3, and the connecting rod 101 is fixedly installed between the outer ring 301 of the bearing 102 and the inner side wall of the bushing 2. The bearing 102, the metal washer 103, and the connecting rod 101 are all located inside the bushing 2. The stepped discs at the top and bottom ends of the round bar 3 are respectively located inside the two bushings 2. The bushings 2 can protect the bearing 102, the connecting rod 101, and the upper and lower ends of the round bar 3.

[0034] In this embodiment, during installation, hinge 1 is first installed on the wall with bolts, and then hinge 4 is threaded onto the passive door. When opening and closing is required, the passive door is rotated, which drives the round bar 3 to rotate. The round bar 3 rotates in the inner ring 302 of the bearing 102 through the rolling action of the balls 303 on the outer ring 301, thereby driving the passive door to open and close. The installation of the metal washer 103 can protect the end face of the bearing 102, enabling it to work normally. The bearing 102 has a certain load-bearing capacity, and the high-strength metal round bar 3 can prevent damage when the passive door is heavy.
