Description

Technical Field

[0001] The utility model relates to the technical field of electrical engineering, in particular to a junction box cover for an aluminum shell motor. Background Art

[0002] Currently, motor junction box covers are structural components used to protect the internal connections and components of the junction box, ensuring safe operation of motor equipment in various environmental conditions. They prevent damage to internal connections caused by dust, moisture, and other external factors. Junction box covers are critical components in a variety of fields, including construction, industrial automation, power supply, and communications. However, insufficient strength can cause the junction box cover to deform or crack when impacted, exposing internal components and posing a potential safety hazard. Summary of the Invention

[0003] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a junction box cover for an aluminum shell motor.

[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical solution: a junction box cover for an aluminum shell motor, comprising a cover body, a sealing gasket is provided on the inner side of the cover body; straight reinforcing ribs are provided on the inner edge of the cover body; and grid-shaped reinforcing ribs are provided on the inner bottom of the cover body.

[0005] Preferably, eight straight reinforcing ribs are evenly arranged around the inner edge of the box cover body; and four grid-like reinforcing ribs are arranged on the inner bottom of the box cover body, which are perpendicular to the eight straight reinforcing ribs.

[0006] Preferably, the thickness of the straight reinforcing rib is more than half of the edge of the box cover, and the height is flush with the edge of the box cover.

[0007] Preferably, the thickness of the grid-shaped reinforcement ribs is half the height of the straight reinforcement ribs.

[0008] Preferably, the box cover body is square, has a cavity, and is integrally cast.

[0009] Preferably, fixing holes are provided at the four corners of the box cover body; the fixing holes are larger on the outside and smaller on the inside, and the hole wall of the inner hole is provided with a threaded groove matching the surface of the screw.

[0010] Preferably, the shape of the sealing gasket is consistent with the shape of the inner edge of the box cover body.

[0011] Preferably, an anti-slip washer is provided on the inner hole of the fixing hole.

[0012] Preferably, two grooves are provided on the outer side of the box cover body.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The utility model arranges reinforcing ribs in the motor junction box. On the one hand, the straight reinforcing ribs are suitable for bearing forces in a single direction and can provide good local support for the inner wall of the junction box cover. The grid-shaped reinforcing ribs are composed of multiple crossed reinforcing ribs, which can evenly distribute the load and improve the overall stability of the bottom of the junction box cover. On the other hand, the thickness of the reinforcing ribs on the inner wall and bottom of the junction box is increased, which means that its cross-sectional area is increased, which directly improves its load-bearing capacity, especially when under pressure, and at the same time helps to distribute stress more evenly, reduce stress concentration, and avoid local damage to the junction box cover.

[0019] In order to enable people skilled in the art to better understand the solution of the present application, the technical solution in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application, as follows.

[0020] Please refer to Figure 1 、 Figure 2 as well as Figure 3 The present invention provides a junction box cover for aluminum-cased motors, comprising a cover body 100, a sealing gasket 200 disposed on the inner side of the cover body 100, straight reinforcing ribs 300 disposed along the inner edge of the cover body 100, and a grid-like reinforcing rib 500 disposed on the inner bottom of the cover body 100. The straight reinforcing ribs are suitable for withstanding forces in a single direction and can provide good local support for the inner wall of the junction box cover. The grid-like reinforcing ribs, composed of multiple intersecting reinforcing ribs, can evenly distribute the load and improve the overall stability of the bottom of the junction box cover.

[0021] Better, such as Figure 1As shown, eight straight reinforcing ribs 300 are evenly arranged along the inner edge of the cover body 100; four grid-like reinforcing ribs 500 are provided on the inner bottom of the cover body 100, perpendicular to the eight straight reinforcing ribs 300. This forms an L-shaped reinforcing rib on the inside of the junction box cover, providing support in a specific direction and preventing damage to the junction box cover due to pressure.

[0022] Better, such as Figure 1 As shown, the straight reinforcing ribs 300 are at least half the thickness of the lid edge and are flush with it; the grid-like reinforcing ribs 500 are half the height of the straight reinforcing ribs 300. Increasing the thickness of the reinforcing ribs on the inner wall and bottom of the junction box increases their cross-sectional area, which directly improves their load-bearing capacity, especially under pressure. It also helps to more evenly distribute stress, reduce stress concentration, and prevent localized damage to the junction box lid.

[0023] Better, such as Figure 1 As shown, the box cover body 100 is square, has a cavity, and is integrally cast, thereby ensuring the integrity of the box cover and reducing assembly costs.

[0024] Better, such as Figure 1 As shown, the shape of the sealing gasket 200 is consistent with the shape of the inner edge of the box cover body 100. It prevents dust, moisture and other external factors from entering the box cover and damaging the electromechanical connection.

[0025] Better, such as Figure 2 As shown, a rubber washer 401 is provided on the inner hole of the fixing hole 400 to provide additional fixing force to prevent the screw from loosening.

[0026] Better, such as Figure 3 As shown, two grooves 500 are provided on the outer side of the box cover body 100. This increases the contact area between the box cover and the hand, improves the friction, and makes it easier to operate when taking the box cover.

[0027] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
