Description

Technical Field

[0001] The utility model relates to the field of distribution cabinets, and in particular to a hinge for a distribution cabinet. Background Art

[0002] The existing hinge for a distribution cabinet, such as the XHZ-102 Xinhuaze black reinforced nylon hinge four-hole square distribution box cabinet insulating plastic hinge sold by Hebei Huaze Machinery Parts Co., Ltd., includes a first hinge piece connected to the main body of the distribution cabinet and a second hinge piece connected to the distribution cabinet door. Both the first hinge piece and the second hinge piece are rectangular. However, during use, the rotation range of the hinge is very large, and the distribution cabinet door is easily hit, and the rotation range of the distribution cabinet door cannot be effectively limited. Moreover, the hinge is prone to vibration, loosening and damage. Summary of the Invention

[0003] In order to solve the above problems, the utility model provides a hinge for a distribution cabinet, which can limit the rotation range of the distribution cabinet door and can effectively reduce vibration.

[0004] To achieve the above object, the utility model provides the following technical solution: A hinge for a distribution cabinet includes a first hinge piece connected to the main body of the distribution cabinet and a second hinge piece connected to the distribution cabinet door. The first hinge piece is rectangular. A U-shaped recess is provided on the front side of the first hinge piece. First mounting holes for connecting to the main body of the distribution cabinet are provided on the periphery of the first hinge piece located at the recess. First vertical plates are provided on both sides of the first hinge piece at the recess. A hinge shaft is provided between the two first vertical plates.

[0005] The second hinge piece is Z-shaped and includes an upper cross plate, a lower cross plate, and an intermediate plate connecting the rear side of the upper cross plate and the front side of the lower cross plate. Second mounting holes for connecting to the distribution cabinet door are provided on the upper cross plate. A U-shaped connecting plate is provided on the upper surface of the rear side of the lower cross plate. The connecting plate has an opening facing forward.

[0006] Both sides of the connecting plate are rotatably passed through the hinge shaft. A spring is provided between both sides of the connecting plate where the hinge shaft is located. Limiting plates for blocking the connecting plate when the second hinge piece rotates to the maximum angle are provided on the front sides of the two first vertical plates.

[0007] During use, the rotation range of the Z-shaped second hinge piece can be limited by the blocking of the limiting plate, thereby avoiding the distribution cabinet door from being hit due to excessive rotation angle.

[0008] Moreover, a spring is provided between both sides of the connecting plate where the hinge shaft is located, which can play a role of buffering and protection, and the hinge is not prone to vibration, loosening and damage.

[0009] Furthermore, both ends of the hinge shaft are detachably connected to end heads at the positions where they pass through the first vertical plates. This facilitates disassembly, assembly and maintenance.

[0010] In summary, the beneficial effects of the present utility model are as follows: This product can limit the rotation range of the distribution cabinet door and effectively shock-absorb the distribution cabinet door. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] As Figure 1 and 2 shown, a hinge for a distribution cabinet includes a first hinge piece 1 and a second hinge piece 2. The first hinge piece 1 is connected to the main body of the distribution cabinet, and the second hinge piece 2 is connected to the distribution cabinet door.

[0018] The main improvement of this product lies in that: the first hinge piece 1 is rectangular, a U-shaped concave portion is provided on the front side of the first hinge piece 1, a first mounting hole 11 is provided on the periphery of the first hinge piece 1 located in the concave portion, and two first bolts are arranged in the first mounting hole 11, and the first bolts are connected to the main body of the distribution cabinet. First vertical plates 3 are provided on both sides of the first hinge piece 1 located in the concave portion, and a hinge shaft 4 is arranged between the two first vertical plates 3; both ends of the hinge shaft 4 are detachably connected to the end 41 at the positions where they pass through the first vertical plates 3, and the detachable connection method is a threaded connection.

[0019] Specifically, the second hinge piece 2 is Z-shaped and includes an upper cross plate 21, a lower cross plate 22, and an intermediate plate 23. The intermediate plate 23 connects the rear side of the upper cross plate 21 and the front side of the lower cross plate 22. Two second mounting holes 25 are provided on the upper cross plate 21, and the second mounting holes 25 are connected to the distribution cabinet door through second bolts. On the upper surface of the rear side of the lower cross plate 22, there is a U-shaped connecting plate 24 with an opening facing forward. The hinge shaft 4 passes through both sides of the connecting plate 24, and the connecting plate 24 can rotate around the hinge shaft 4. A spring 5 is provided between the two sides of the connecting plate 24 where the hinge shaft 4 is located, and both ends of the spring 5 press against the connecting plate 24. A limiting plate 31 is provided on the front side of the two first vertical plates 3. When the second hinge piece 2 rotates to the maximum angle, preferably 90°, the limiting plate 31 blocks the connecting plate 24.
