Description

TECHNICAL FIELD

[0001] The application relates to the technical field of industrial power supplies, in particular to a machine case. BACKGROUND

[0002] In the field of industrial power supplies, with the continuous progress of technology and the increasing demand for application, higher and higher requirements are put forward for the IP level of the shell of the equipment. The IP level is a key indicator for measuring the protection capability of the shell of the electrical equipment, which reflects the protection capability of the equipment against solid objects (such as dust) and liquids (such as water) from the outside. The sealing performance of the sheet metal case, as an important part of the industrial power supply, directly affects the running stability and service life of the entire device.

[0003] At present, in the sealing treatment of the sheet metal case, the most common method is to attach sealing cotton or sealing strips on the flat panel. This method forms a certain sealing effect when the panel is assembled with other parts through the elasticity and compressibility of the sealing material, thereby preventing dust and moisture from the outside from entering the inside of the case. Sealing cotton and sealing strips are widely used due to their low cost and simple construction.

[0004] However, although attaching sealing cotton or sealing strips on the flat panel can form a certain sealing effect, in the actual assembly process, due to the thickness and elasticity of the sealing material, the assembly gap between the panel and other parts is often uneven, causing the entire panel surface to appear uneven. This not only seriously affects the overall appearance of the sheet metal case, but also may cause the sealing performance to decrease due to assembly errors, which cannot meet the high IP level standard. CONTENT OF THE INVENTION

[0005] The application provides a sealing structure and a machine case to solve the problem of uneven panel caused by the existing sealing method.

The arrangement of the groove also limits the filler body, ensuring the stability of the sealing position.

[0014] In an alternative embodiment, a plurality of first through holes are arranged on the flange, a plurality of second through holes are arranged on the plate body, the plurality of first through holes arranged on the flange and the plurality of second through holes arranged on the plate body are arranged one-to-one respectively, and the plate body is adapted to be connected to the flange by a connecting piece inserted into the first through holes and the second through holes.

[0015] Beneficial effects: by arranging the first through holes and the second through holes on the flange and the plate body respectively, the connecting effect of the connecting piece can be achieved, and the first through holes and the second through holes are pre-fabricated, which can improve the convenience during assembly and improve production efficiency.

[0016] In an alternative embodiment, a plurality of the first through holes are arranged at the edge of the flange along the circumference of the flange, and a plurality of the second through holes are arranged at the edge of the plate body along the circumference of the plate body.

[0034] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0035] The embodiments of the present application will be described below in combination with Figures 1 to 5 .

[0036] According to the embodiments of the present application, a machine case is provided, which comprises a box body 1, a plate body 3 and a filling body. The box body 1 is provided with an opening 2. The plate body 3 is connected with the box body 1 and is adapted to block the opening 2. The box body 1 and / or the plate body 3 is provided with a groove 4, and the groove 4 is located between the box body 1 and the plate body 3 and extends along the circumference of the opening 2. The filling body is located in the groove 4 so as to keep the plate body 3 and the box body 1 sealed.

[0037] It can be understood that the groove 4 can be arranged on the plate body 3, i.e. the groove 4 and the plate body 3 are configured as an integral molding structure. When the plate body 3 and the box body 1 are installed, the filling body can be arranged in the groove 4 on the plate body 3 first, and then the plate body 3 and the box body 1 are buckled to realize the sealing of the opening 2. The filling body in the groove 4 is extruded to seal the gap between the plate body 3 and the box body 1.

[0038] It can be understood that the groove 4 can also be arranged on the box body 1, i.e. the groove 4 and the box body 1 are configured as an integral molding structure. When the plate body 3 and the box body 1 are installed, the filling body can be arranged in the groove 4 on the box body 1 first, and then the plate body 3 and the box body 1 are buckled to realize the sealing of the opening 2. The filling body in the groove 4 is extruded to seal the gap between the plate body 3 and the box body 1.

[0039] It can be understood that the groove 4 can also be provided on the plate body 3 and the box body 1, that is, the groove 4 is integrally formed with the plate body 3, and the groove 4 is integrally formed with the box body 1. When the plate body 3 and the box body 1 are installed, the filler can be arranged in the groove 4, and then the plate body 3 and the box body 1 are buckled to seal the opening 2. The filler in the groove 4 is extruded to seal the gap between the plate body 3 and the box body 1.

[0040] It can be understood that the groove 4 can also be provided on the plate body 3 and the box body 1, that is, the groove 4 is integrally formed with the plate body 3, and the groove 4 is integrally formed with the box body 1. When the plate body 3 and the box body 1 are installed, the filler can be arranged in the groove 4, and then the plate body 3 and the box body 1 are buckled to seal the opening 2. The filler in the groove 4 is extruded to seal the gap between the plate body 3 and the box body 1.

[0041] It should be noted that the groove 4 extends along the circumference of the opening 2, so that it is arranged around the circumference of the opening 2. After the box body 1 and the plate body 3 are installed, the filler can seal the circumference of the opening 2.

[0042] In this embodiment, by providing the groove 4 on the plate body 3 and / or the box body 1, the filler for sealing can be accommodated. When the plate body 3 and the box body 1 are abutted and the filler is extruded, the filler can deform in the groove 4. The gap between the plate body 3 and the box body 1 is sealed, and the filler is prevented from occupying the gap between the plate body 3 and the box body 1, thereby ensuring the flatness of the plate body 3 and the box body 1 after assembly.

[0043] In one embodiment, the box body 1 is provided with a flange 5, the flange 5 is arranged along the circumference of the opening 2, the flange 5 abuts the plate body 3, and the groove 4 is arranged on the flange 5 and / or the plate body 3.

[0044] It should be noted that the flange 5 is integrally formed with the box body 1, and the flange 5 is arranged in a closed loop structure, so that the flange 5 can be arranged around the circumference of the opening 2. When the plate body 3 and the flange 5 are spliced, the edges of the plate body 3 and the flange 5 abut, that is, the contact area of the two is completely arranged outside the opening 2, and the filler is extruded synchronously, so that the opening 2 can be completely sealed.

[0045] In this embodiment, the flange 5 can be connected to the plate body 3, and the connection mode of the flange 5 and the plate body 3 can provide the option for the arrangement of the groove 4, that is, the groove 4 can be arranged on the flange 5, or on the plate body 3, or on both the plate body 3 and the flange 5, thereby greatly improving the flexibility of installation.

[0046] In one embodiment, the recess 4 is provided as a punching structure.

[0047] It can be understood that the recess 4 is formed by punching the plate body 3 and / or the flange 5 by a punching machine.
