Description

Sealing box

Technical Field

The application relates to the field of boxes, in particular to a sealing box.

Background

Boxes made of thin-walled metal are known for carrying electrical equipment, and the sealing of the boxes is mainly carried out in two ways:

(1) a stud is welded in the box body, a counter bore is formed in the box cover, and the screw is connected with the stud of the box body through the counter bore. In this way, when the depth dimension of the box body is larger, the stud is too long. The screw hole is easy to deviate after welding, so that the box cover and the screw hole are not aligned and cannot be installed.

(2) The outer side surface of the box body is welded with a lug, and the lug is provided with a screw hole. The corresponding position of the box cover is welded with a lug, and a counter bore is arranged on the lug. The box body and the box cover are fixed through screws. This approach increases the overall area of the tank and is not suitable for use when the size requirements are high.

Detailed Description

Exemplary embodiments of the present application are described below with reference to the accompanying drawings. It should be understood that the detailed description is only intended to teach one skilled in the art how to practice the present application, and is not intended to be exhaustive or to limit the scope of the application.

Fig. 1 and 2 show a seal box according to an embodiment of the present application, which includes a box body 1, a box cover 2, a box seal ring (not shown in the drawings), screws 3 (an example of a fastener), and screw seal rings 4.

Referring to fig. 1, a first wall portion (opening end wall) 11 of the case 1 may be opened with an opening 11a, the opening 11a communicating the inside and outside of the case 1. A projection 12 extending along the entire circumference of the edge portion may be fixed to the edge portion of the opening 11 a. The projection 12 may include a second wall portion 121 and a third wall portion 122. Here, the second wall portion 121 may extend from an inner edge portion of the opening 11a perpendicularly to the first wall portion 11, and the third wall portion 122 may extend from the second wall portion 121 parallel to the first wall portion 11 such that the convex portion 12 protrudes to the outside and is U-shaped in cross section with the first wall portion 11. A plurality of fixing blocks 13 may be fixed to an inner surface of the second wall portion 121, and each fixing block 13 may be opened with a screw hole 13 a. The cover 2 may be countersunk 2a corresponding to the threaded holes 13 a.

Referring to fig. 2, when the cover 2 covers the opening 11a, a case packing may be located between the third wall portion 122 and the cover 2. The screw sealing ring 4 can be sleeved on the screw 3, and the screw 3 can penetrate through the counter bore 2a and be screwed into the threaded hole 13a to fix the box cover 2. In the process of screwing the screw 3 in, the box cover 2 can press the box body sealing ring to enable the box body 1 and the box cover 2 to be connected in a sealing mode. Meanwhile, the screw 3 can press the screw sealing ring 4 to make the screw 3 and the box cover 2 connected in a sealing way. In this way, the protrusion 12 can provide a fixed position for the fixed block 13 at a position closer to the opening 11a, so that the fixed block 13 can have a higher positioning accuracy, and the counter bore 2a on the case cover 2 can be easily aligned with the threaded hole 13a on the fixed block 13. In addition, the fixing block 13 is disposed on the inner surface of the second wall portion 121, so that the fixing block 13 does not occupy the space outside the case 1, and the entire volume of the sealing case is small.

The opening 11a may be square. Accordingly, the fixed block 13 may be square and the number of the fixed blocks 13 may be four. The right angle of the fixing block 13 may be fitted with the right angle of the opening 11a to help the fixing block 13 to be positioned better. Four fixing blocks 13 may be welded to four corners of the opening 11a, respectively.

The surface of the case 1 may be provided with a handle 14 to make the sealed case portable. When the electrical equipment is placed in the cabinet 1, the surface of the cabinet 1 may be provided with an interface 15 to facilitate electrical connection of the electrical equipment with a cable outside the cabinet 1.

To facilitate the installation of the cover 2, a case seal ring may be adhered to the cover 2 at a position corresponding to the third wall portion 122.

The second wall portion 121 and the third wall portion 122 may be formed integrally with the first wall portion 11. Specifically, the case 1 may be made of metal, and the second wall portion 121 and the third wall portion 122 may be formed by bending the first wall portion 11. Thus, the processing technology of the box body 1 is simple.

The application has at least the following advantages:

(i) the protrusion 12 can provide a fixing position for the fixing block 13 at a position closer to the opening 11a, so that the fixing block 13 can have a high positioning accuracy, and the counter bore 2a on the case cover 2 is easily aligned with the threaded hole 13a on the fixing block 13.

(ii) The fixing block 13 is disposed on the inner surface of the second wall portion 121, so that the fixing block 13 does not occupy the space outside the case 1, and the entire volume of the seal case is small.

It should be understood that the above-described embodiments are exemplary only, and are not intended to limit the present application. Various modifications and alterations of the above-described embodiments may be made by those skilled in the art in light of the teachings of this application without departing from the scope thereof.

It should be understood that when the case seal ring is not provided between the third wall portion 122 and the case lid 2, the projection 12 is not limited to extending along the entire periphery of the edge portion of the opening 11a, and may be intermittent.

It should be understood that the fastener is not limited to the screw 3. The box 1 and the box cover 2 may be secured using any possible fasteners known to those skilled in the art.

It should be understood that the case 1 and the case lid 2 are not limited to being sealingly connected by a case gasket. For example, the box seal may be replaced with a gasket seal or sealant, etc. The tank packing is not limited to being located between the third wall portion 122 and the tank cover 2, and may be located at any possible position between the tank 1 and the tank cover 2. The case seal ring is not limited to being bonded to the case lid 2, and may be bonded to the third wall portion 122.

It should be understood that the fixing block 13 is not limited to being welded to the second wall portion 121, but may be connected to the protrusion 12 at any possible location in any possible manner known to those skilled in the art.

It should be understood that the second wall portion 121 is not limited to being perpendicular to the first wall portion 11, nor is the third wall portion 122 limited to being parallel to the first wall portion 11. The second wall part 121 and the third wall part 122 may form any possible angle with the first wall part 11.
