Switch box sheet

Abstract

The invention relates to the field of accessories of electrical products, in particular to a switch box sheet. The switch box sheet comprises a periphery interference fit section and an internal groove gap sleeve-in section, which are integrally connected with each other, wherein the periphery interference fit section is provided with bosses with first guide structures on the internal surfaces; through holes capable of exhausting are arranged on the tail end face of the internal groove gap sleeve-in section; and second guide structures convenient for movable footing parts to sleeve in are arranged at the mouth of the internal groove gap sleeve-in section. The switch box sheet is convenient to dismantle, can remove the collected gases and is lower in cost.

Description

technical field [0001] The invention relates to the field of electrical product accessories, in particular to a switch box piece. Background technique [0002] The existing PVC grooved pipe switch box piece structure, such as Figures 1 to 3 As shown, it includes a boss section with peripheral interference matching and a slot section that is inserted into the gap of the inner groove, both of which are solid and integral. Since the inner surface of the three-sided barb boss of the peripheral matching section is at right angles, after the barb boss of the peripheral interference matching section of the switch box piece and the main body of the switch box are installed in interference, it is difficult to disassemble and separate, even if it is disassembled by force. Damaged, the possibility of product reuse is low. In addition, because the inner surfaces of the three-sided barb bosses of the existing products are all right angles, in order to avoid the edging between the three...

Problems solved by technology

In addition, because the inner surfaces of the three-sided barb bosses of the existing products are all right angles, in order to avoid the edging between the three-sided bosses and affecting the assembly with the main body, when designing the mold, the peripheral three-sided right-angle barb bosses must be The mold is released as a whole, and the mold must be opened along the direction of the left and right right-angled barb surfaces. The mold opening method is single and the requirements are high.

Secondly, the contour edge of the opening part of the inner groove in the inner groove gap is a sharp angle. When the movable foot column is installed with the switch box piece, the movable foot column cannot be installed smoothly due to the sharp edge of the outline. The slot segment that enters the inner slot gap of the switch box piece

Finally, since the inner groove is a blind groove blocked on three sides, when the mold is opened, it is easy to collect gas in the blind groove, resulting in the product sticking to the mold

In addition, because the inner tank adopts a three-sided sealing structure, the product uses more materials and the cost is higher
