Description

Technical Field

[0001] The utility model relates to the technical field of power boxes, in particular to an upper cover anti-misoperation closed power box. Background Art

[0002] A power box usually consists of a box body and an openable cover body. When performing internal maintenance on the power box, the cover body can be opened. In order to prevent the cover body from detaching from the box body when it is opened and reduce the risk of the cover body being lost, the cover body is usually hinged to the box body. When the cover body is opened, it can be rotated and opened.

[0003] When the cover body of the existing power box is rotated and opened, there is no positioning mechanism to lock the rotation angle of the cover body, resulting in the cover body being easily closed due to misoperation after it is opened, which causes inconvenience to the internal maintenance of the power box. Content of the Utility Model

[0004] The purpose of the utility model is to provide an upper cover anti-misoperation closed power box to solve the problem of misoperation closing of the cover body of the existing power box due to the lack of an angle limiting mechanism.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: An upper cover anti-misoperation closed power box, comprising:

[0006] A box body, with a hinge seat provided at one end;

[0007] A cover plate, one end of which is rotatably installed on the hinge seat through a connecting column;

[0008] A spring piece, which is arranged in the mounting hole on the hinge seat. One end of the spring piece is fixedly installed on the box body. A convex rib is provided on the spring piece, and an arc-shaped groove corresponding to the convex rib in position is provided on the connecting column.

[0009] As a further description of the above technical scheme:

[0010] Several parallel spring pieces are provided on the hinge seat.

[0011] As a further description of the above technical scheme:

[0012] Several parallel partitions are provided on the back of the connecting column.

[0013] As a further description of the above technical scheme:

[0014] A first convex plate is provided at the end of the cover plate, a second convex plate corresponding to the first convex plate in position is provided on the box body, a first through hole is provided on the first convex plate, and a second through hole corresponding to the first through hole in position is provided on the second convex plate.

[0015] As a further description of the above technical scheme:

[0016] A silica gel sealing ring is provided at the opening on the top of the box body.

[0017] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0018] 1. In the present utility model, the power supply box is integrally made of BMC thermosetting material. When the cover plate is opened, during the process of the cover plate rotating and opening, the surface of the connecting column squeezes the convex rib of the elastic sheet. When the cover plate is opened to a specific angle, the convex rib on the elastic sheet is caught in the arc-shaped groove on the connecting column, realizing the locking of the opening angle of the cover plate, preventing the cover plate from accidentally closing due to the lack of an angle limiting mechanism, and facilitating the maintenance of the interior of the power supply box.

[0019] 2. In the present utility model, when the cover plate is closed, since the surface of the convex rib is an arc surface and it is caught in the arc-shaped groove, the elastic sheet can be squeezed and deformed by closing the cover plate forcefully, realizing the unlocking and completing the closing of the power supply box.

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1

[0031] Please refer to Figures 1-6 , the present invention provides a technical solution: an upper cover anti-mis-touch closed power box, including:

[0032] A box body 1, with a hinge seat 11 provided at one end thereof;

[0033] A cover plate 2, one end of which is rotatably mounted on the hinge seat 11 through a connecting column 21;

[0034] An elastic sheet 3, which is arranged in the mounting hole 111 on the hinge seat 11. One end of the elastic sheet 3 is fixedly installed on the box body 1. There is a convex rib 31 on the elastic sheet 3, and an arc-shaped groove 211 corresponding to the convex rib 31 is arranged on the connecting column 21.

[0035] A plurality of elastic sheets 3 arranged in parallel are provided on the hinge seat 11, effectively ensuring the locking effect on the cover plate 2.

[0036] A plurality of circumferentially arranged arc-shaped grooves 211 are arranged on the connecting column 21. For example, 3 arc-shaped grooves 211 are specifically adopted in this application to form a "damping feeling" during the opening process.

[0037] A silicone sealing ring 4 is arranged at the top opening of the box body 1 to improve the sealing effect of the cover plate 2.

[0038] Working principle: The power supply box is integrally made of BMC thermosetting material. When the cover plate 2 is opened, during the process of the cover plate 2 rotating and opening, the surface of the connecting column 21 presses the rib 31 of the elastic sheet 3. When the cover plate 2 is opened to a specific angle, the rib 31 on the elastic sheet 3 is caught in the arc-shaped groove 211 on the connecting column 21, locking the opening angle of the cover plate 2, preventing the cover plate 2 from accidentally closing due to the lack of an angle limiting mechanism, and facilitating the maintenance of the interior of the power supply box. When the cover plate 2 is closed, since the surface of the rib 31 is an arc surface and it is caught in the arc-shaped groove 211, the elastic sheet 3 can be deformed by pressing the cover plate 2 forcefully to release the locking and complete the closing of the power supply box.

[0039] Embodiment 2

[0040] Others are the same as Embodiment 1, the difference is that: a first convex plate 22 is provided at the end of the cover plate 2, a second convex plate 12 corresponding to the first convex plate 22 in position is provided on the box body 1, a first through hole 221 is provided on the first convex plate 22, and a second through hole corresponding to the first through hole 221 in position is provided on the second convex plate 12. When the cover plate 2 is closed, the first convex plate 22 fits against the second convex plate 12, and the locking member (specifically, a steel wire is used) passes through the first through hole 221 and the second through hole in sequence to lock the cover plate 2.

[0041] Embodiment 3

[0042] Others are the same as Embodiment 1, the difference is that: a plurality of partition plates 212 arranged in parallel are provided on the back surface of the connecting column 21. The partition plates 212 are used to limit the maximum opening angle of the cover plate 2. When the cover plate 2 rotates to the maximum opening angle, the partition plates 212 abut against the hinge seat 11. An anti-tilting plate 213 is provided between two adjacent partition plates 212. The anti-tilting plate 213 is used to prevent the partition plates 212 from deforming and tilting, ensuring the stability of the hinge structure of the cover plate 2.

[0043] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
