Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, specifically to a distribution box cover. Background Technology

[0002] A distribution box is an electrical device mainly used for distributing electrical energy and controlling and protecting circuits. The cover of the distribution box is mainly to protect the electrical components inside the distribution box. It can prevent dust, moisture, foreign objects and other contaminants from entering the distribution box. For example, in industrial environments with a large amount of dust, without a cover, dust may enter the distribution box and accumulate on the electrical components, affecting heat dissipation and potentially causing short circuits. In outdoor distribution boxes, the cover can effectively block rainwater, preventing rainwater from dripping onto the electrical components and causing malfunctions.

[0003] Currently, the front cover of a distribution box lacks an auxiliary anti-accidental opening mechanism. While the cover is simple to operate by simply flipping it upwards, it is also prone to accidental opening. This not only allows external dust to enter the distribution box but also easily damages or short-circuits the electrical components inside. Therefore, this paper proposes a new distribution box front cover design that incorporates an auxiliary anti-accidental opening mechanism. This mechanism utilizes plug-in and limit switches to improve the stability of the cover's closure, preventing accidental opening due to external forces and preventing external dust and moisture from entering the distribution box, thereby improving its performance. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a distribution box cover to improve the stability of the cover's closure, prevent accidental opening due to external forces, and prevent external dust and moisture from entering the distribution box, thereby improving its performance.

[0005] The technical solution adopted by this utility model to solve its technical problem is a distribution box cover, including a panel, a fixing frame and a door cover. The surface of the panel is connected to the fixing frame by bolts, and the door cover is rotatably connected inside the fixing frame.

[0006] The fixed frame is connected by welding to the insert post, and the inner surface of the door cover is provided with insertion holes corresponding to the insert post.

[0007] By adopting the above technical solution, an anti-accidental opening mechanism can be added. By using plug-in and limit methods, the stability of the cover closure is improved, and external dust and moisture are prevented from entering the distribution box due to accidental opening. The structure is simple, the cost is low, and the use is more reasonable and reliable.

[0008] Specifically, the top of the door cover is connected to a protruding strip by bolts, and the top of the fixed frame is provided with an inner groove corresponding to the protruding strip. A spring is installed on the top of the inner groove on one side of the protruding strip through a spring seat.

[0009] By adopting the above technical solution, an auxiliary sealing structure can be formed. By using the staggered interlocking method, gaps in the cover during use can be reduced, thereby improving the sealing performance and improving the use effect. By pushing with spring force, the closing position accuracy can be improved after the cover is closed.

[0010] Specifically, mounting seats are provided on both sides of the door cover, and a damping shaft is provided on one side of the mounting seat. The mounting seat is rotatably connected to the fixed frame through the damping shaft.

[0011] By adopting the above technical solution, the door cover can be easily connected to the fixed frame for rotation, while also having a certain amount of sliding displacement space.

[0012] Specifically, a slider is bolted to the other side of the mounting base, and grooves are provided on both sides of the door cover. The mounting base is slidably connected to the grooves via the slider, and a transparent window panel is bolted to the inside of the door cover.

[0013] By adopting the above technical solution, it is easy to install the limit switch and move the connecting door cover, and it is easy for operators to directly observe the working situation inside the distribution box from the outside of the cover.

[0014] Specifically, mounting grooves are provided on both sides of the fixed frame, and a notch is provided at the bottom of the fixed frame.

[0015] By adopting the above technical solution, it is easy to install the mounting base, and it is easy for operators to lift the door cover from the bottom and flip it outwards with their fingers.

[0016] Specifically, the surface of the panel has a window.

[0017] By adopting the above technical solutions, it is easier for operators to perform maintenance and other tasks.

[0018] The beneficial effects of this utility model are:

[0019] The distribution box cover described in this utility model, through the setting of a panel, fixing frame, plug, door cover and plug hole, can increase the auxiliary anti-accidental opening structure. By using the up and down sliding and plug-in limiting method, the stability of the cover is improved and the external dust and moisture caused by accidental opening by external force are prevented from entering the distribution box. The structure is simple and compact, low cost and more reasonable and stable in use.

[0020] The distribution box cover described in this utility model, through the setting of the cover, convex strip, inner groove and spring, can increase the auxiliary sealing mechanism. By using sliding displacement and sleeve shielding, the gap of the cover is reduced and the sealing performance is improved. At the same time, the spring force can be used to push and improve the success rate of the cover closing operation. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0030] To improve the stability of the cover closure, prevent accidental opening due to external forces, and prevent external dust and moisture from entering the distribution box, thereby improving performance, such as... Figure 1-3 As shown, the present invention provides a distribution box cover, which includes a panel 1, a fixing frame 2 and a door cover 3. The surface of the panel 1 is connected to the fixing frame 2 by bolts, and the door cover 3 is rotatably connected inside the fixing frame 2.

[0031] The fixed frame 2 is connected by welding to the insert post 201, and the inner surface of the door cover 3 is provided with an insertion hole 301 corresponding to the insert post 201.

[0032] In use, the panel 1, fixing frame 2, plug post 201, door cover 3 and plug hole 301 can be used to add an anti-accidental opening mechanism. By using plug-in and limit methods, the stability of the cover closing is improved, and external dust and moisture are prevented from entering the distribution box due to accidental opening. The structure is simple, the cost is low, and the use is more reasonable and reliable.

[0033] To improve the sealing performance during use, for example, such as Figure 3 , Figure 5 As shown, the present invention also includes a protrusion 302 bolted to the top of the door cover 3, an inner groove 202 corresponding to the protrusion 302 being opened in the top of the fixing frame 2, and a spring 203 being installed in the top of the inner groove 202 on one side of the protrusion 302 via a spring seat.

[0034] During use, the protrusion 302 and the inner groove 202 can form an auxiliary sealing structure. By using the staggered connection method, the gaps in the cover during use are reduced, thereby improving the sealing performance and improving the use effect. The spring 203 pushes the cover 3 to improve the closing position accuracy after the cover 3 is closed.

[0035] For example, such as Figure 4 As shown, the present invention also includes mounting bases 303 on both sides of the door cover 3, a damping shaft 304 on one side of the mounting base 303, and the mounting base 303 is rotatably connected to the fixing frame 2 through the damping shaft 304.

[0036] In use, the mounting base 303 and the damping shaft 304 facilitate the rotation of the door cover 3 to connect with the fixed frame 2, while also providing a certain amount of sliding displacement space.

[0037] For example, such as Figure 3 , Figure 4 As shown, the present invention also includes a slider 305 connected to the other side of the mounting base 303 by bolts, and grooves 306 are provided on both sides of the door cover 3. The mounting base 303 is slidably connected to the grooves 306 by the slider 305. A transparent window panel 307 is connected to the inside of the door cover 3 by bolts.

[0038] In use, the sliding block 305 and the sliding groove 306 facilitate the limited movement of the mounting base 303 to connect the door cover 3 for use, and the transparent window panel 307 allows the operator to directly observe the working conditions inside the distribution box from the outside of the cover.

[0039] For example, such as Figure 2 As shown, the present invention also includes mounting grooves 204 on both sides of the fixing frame 2 and a notch 205 at the bottom of the fixing frame 2.

[0040] In use, the mounting groove 204 facilitates the installation of the mounting base 303, and the notch 205 allows the operator to lift the cover 3 from the bottom with their fingers and flip it outwards.

[0041] For example, such as Figure 6 As shown, the present invention also includes a window 101 provided on the surface of the panel 1.

[0042] When in use, window 101 facilitates maintenance and other operations for operators.

[0043] When using this utility model, the operator first needs to lift the cover 3 upwards from the recess 205 with their fingers to separate the plug 201 from the socket 301. Then, pull the cover 3 to flip it outwards and use the damping shaft 304 to adjust its flipping angle and height position so that the operator can work on the distribution box through the window 101. After completing the operation, push it inwards to the top again, and at the same time push the cover 3 to flip inwards to the inside of the fixed frame 2. Use the spring 203 to push the cover 3 downwards so that the plug 201 is inserted into the corresponding socket 301, completing the auxiliary positioning and anti-accidental opening mechanism. This not only improves the stability of the cover closing, but also prevents external dust and moisture from entering the distribution box by accident, making it more reasonable and reliable to use.

[0044] Furthermore, the cooperation between the fixed frame 2, the inner groove 202 and the protrusion 302 can improve the sealing performance after the cover is closed, reduce the gaps in the door cover 3 during use, and make the overall structure simple and compact, and more reasonable and convenient to use.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
