During the process of electrical integration and actual use, in order to facilitate the integration, testing, maintenance of electrical components inside the cabinet and the overall coordination and aesthetics outside the cabinet, the directions of movable parts such as doors and rotating mechanisms are often specified.
[0003] The industrial cabinet hinges in the prior art do not have the function of limiting the cabinet door. When the staff repairs the inside of the industrial cabinet, the unconstrained industrial cabinet door is likely to collide with the operator. Therefore, an industrial cabinet hinge is needed.
[0004] It should be noted that the above content belongs to the technical cognition scope of the inventor and does not necessarily constitute the prior art. Summary of the Utility Model
[0005] In order to solve the above problems, the purpose of the utility model is to provide an industrial cabinet hinge.
[0006] To achieve the above purpose, the utility model provides an industrial cabinet hinge, including a positive hinge body. A rotating component is arranged inside the positive hinge body, and a buffer component is arranged at the bottom of the rotating component. The buffer component includes a mounting plate fixedly installed inside the positive hinge body. An activity hole is formed inside the mounting plate. A buffer rod is movably sleeved inside the activity hole. A limiting ring is movably sleeved outside the buffer rod. A return spring is sleeved between the limiting ring on the buffer rod and the mounting plate.
[0007] In one example, the rotating component includes two guiding grooves formed outside the secondary hinge body. A first connecting rod is slidably sleeved inside the two guiding grooves. The secondary hinge body is movably sleeved outside the first connecting rod.
[0008] In one example, a buffer plate is arranged at the top of the buffer rod. A connecting groove is formed at the top of the buffer plate. The connecting groove is in contact with the outside of the first connecting rod.
[0009] In one example, a rotating groove is formed outside the secondary hinge body. A second connecting rod is fixedly installed inside the secondary hinge body. The second connecting rod is in contact with the inside of the rotating groove.
[0010] In one example, a limiting block is installed outside one side of the buffer plate. The limiting block is located at the top of the limiting ring.
[0011] In one example, a plurality of fixing plates are provided on the outside of the positive hinge body, and fixing holes are formed in both the fixing plates and the inside of the sub-hinge body.
[0012] An industrial cabinet hinge proposed by the present utility model can bring the following beneficial effects:
[0013] By pulling the sub-hinge body, the sub-hinge body drives the first connecting rod to slide downward along the inside of the guiding groove. Furthermore, the buffer plate is extruded by the first connecting rod, so that the buffer rod at the bottom of the buffer plate moves downward inside the moving hole, causing the limiting block to contact the limiting ring. Then, the reset spring is extruded through the limiting ring, thereby opening the cabinet door and keeping a certain distance between the door and the cabinet door, avoiding the unconstrained industrial cabinet door from hurting the operator.

Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more solutions or examples.
[0028] As Figures 1 to 6 shown, an embodiment of the present utility model provides an industrial cabinet hinge, which includes a positive hinge body 2. A rotating assembly is provided inside the positive hinge body 2, and a buffer assembly is provided at the bottom of the rotating assembly. The buffer assembly includes a mounting plate 6 fixedly installed inside the positive hinge body 2. An activity hole 7 is opened inside the mounting plate 6. A buffer rod 5 is movably sleeved inside the activity hole 7. A limiting ring 10 is movably sleeved outside the buffer rod 5. A return spring 8 is sleeved between the limiting ring 10 on the buffer rod 5 and the mounting plate 6.
[0029] As Figure 3 shown, the rotating assembly includes two guiding grooves 13 opened outside the secondary hinge body 1. A first connecting rod 11 is slidably sleeved inside the two guiding grooves 13. The secondary hinge body 1 is movably sleeved outside the first connecting rod 11.
[0030] As Figure 3 and Figure 5 shown, a buffer plate 12 is provided at the top of the buffer rod 5. A connecting groove 14 is opened at the top of the buffer plate 12. The connecting groove 14 is in contact with the outside of the first connecting rod 11.
[0031] As Figure 3 shown, a rotating groove 15 is opened outside the secondary hinge body 1. A second connecting rod 16 is fixedly installed inside the secondary hinge body 1. The second connecting rod 16 is in contact with the inside of the rotating groove 15. The secondary hinge body 1 rotates around the outside of the second connecting rod 16 through the rotating groove 15.
[0032] As Figure 4 and Figure 3 and Figure 5 shown, a limiting block 9 is installed outside one side of the buffer plate 12. The limiting block 9 is located at the top end of the limiting ring 10. Thus, the buffer rod 5 at the bottom of the buffer plate 12 moves downward inside the activity hole 7, so that the limiting block 9 is in contact with the limiting ring 10. Then, the return spring 8 is compressed through the limiting ring 10, thereby opening the cabinet door.
[0033] As Figure 1 shown, a plurality of fixing plates 4 are provided on the outside of the positive hinge body 2, and fixing holes 3 are respectively formed in the fixing plates 4 and the inside of the secondary hinge body 1. First, the fixing holes 3 formed in the secondary hinge body 1 and the positive hinge body 2 are respectively horizontally installed on the industrial cabinet door and the industrial cabinet through external fixing members.
[0034] Working principle:
[0035] When using this industrial cabinet hinge, first, the fixing holes 3 formed in the secondary hinge body 1 and the positive hinge body 2 are respectively horizontally installed on the industrial cabinet door and the industrial cabinet through external fixing members. When it is necessary to close the industrial cabinet door, the external industrial cabinet door connected to the secondary hinge body 1 is pushed by an external force, so that the secondary hinge body 1 rotates around the outside of the second connecting rod 16 through the rotating groove 15, so that the secondary hinge body 1 drives the first connecting rod 11 to slide upward inside the guiding groove 13, and then the return spring 8 outside the buffer rod 5 is stretched. Thus, during the stretching process, the return spring 8 drives the limiting ring 10 to contact the limiting block 9, thereby completing the closing of the cabinet door. When it is necessary to open the external industrial cabinet door, by pulling the secondary hinge body 1, the secondary hinge body 1 drives the first connecting rod 11 to slide downward inside the guiding groove 13, and then the buffer plate 12 is extruded by the first connecting rod 11. Furthermore, the buffer rod 5 at the bottom of the buffer plate 12 moves downward inside the moving hole 7, so that the limiting block 9 contacts the limiting ring 10, and then the return spring 8 is extruded through the limiting ring 10, thereby opening the cabinet door, and further keeping a certain distance between the door and the cabinet door to prevent the unconstrained industrial cabinet door from hurting the operator.
