Description

Frame device of the box

technical field

The utility model relates to an electric device, in particular to a frame device suitable for a box body of a distribution box.

Background technique

General electrical equipment is assembled in a distribution box to achieve the purpose of safe use, and the distribution box includes a frame device and a box shell covering the outside of the frame device, and the frame device is made of multiple The support frame is assembled.

Patents such as Taiwan Application No. 87208913, No. 87208913A01, No. 87208913A02, No. 94112854 and No. 94112856 have disclosed frame bars in many different implementation modes. The common structural features of the frame bars are all formed by a The inner wall and an outer wall are formed, as shown in FIG. 1 , it is a frame bar disclosed by No. 87208913A01. An inner wall 1 of the frame bar has two abutting surfaces 101 and a frame between the abutting surfaces 101 Combining the concave surface 102, one outer wall 2 has two side surfaces 201 that fit with the abutment surface 101 and are vertically connected, and two hemming surfaces 202 formed by vertically bending the side edges of the side surfaces 201, Said flanging surface 202 is folded back and fixed on the abutting surface 101 of the inner wall 1 for crimping, and the combining concave surface 102 separating the inner wall 1 forms a combining groove 3, and is formed between the said flanging surface 202 and the abutting surface 101. Do spot welding by face 101.

There are following problems in this frame bar during manufacture and use:

1. Both the inner wall 1 and the outer wall 2 are open structures, therefore, the structural strength of the frames formed by the fixed connection of the inner wall 1 and the outer wall is relatively insufficient.

2. The inner wall 1 and the outer wall 2 are connected inside and outside. Therefore, the dimension matching between the inner wall 1 and the outer wall 2 must be accurate. For example, the abutment surface 101 and the side surface 201 must have a better The verticality of the hemming surface 202 must have a better parallelism, and the depth generated by the hemming surface 202 must be sufficient to accommodate the abutment surface 101... Therefore, the overall size control is not easy , and once there is a slight error in the size, it will lead to problems of weak structural strength and difficult combination.

Third, as shown in Figure 2, when the above-mentioned frame bars are assembled with a case shell 3, one of the flanged surfaces 202 of the frame body has enough area for a side plate 301 of the case case 3 to be fixedly set position, but the area of the side edge of another flange 202 parallel to this flange 202 is very small, and can only be used for a door panel 302 of the box shell 3 to abut against and locate, so that when the electrical box wants to expand the assembly quantity, the expanded The direction can only be along the front and rear directions shown in Figure 2, but not the left and right directions. If the front and rear directions are restricted by the walls of the factory building, machines, etc., the purpose of expanding the number of assemblies cannot be achieved. Therefore, This frame structure cannot produce good scalability.
