Problems solved by technology

[0002] The switch box of the high-pressure cleaner is provided with a screw connection hole for screwing the screw. By screwing the screw into the screw connection hole, it plays the role of assembly and fixation. However, the existing screw connection hole is easy to screw into the screw. When the tightened screws are unscrewed, the plastic screw connection holes are often cracked, causing the entire switch box to be scrapped, causing serious waste, delaying the work process, and slowing down work efficiency

Abstract

The invention provides a switch box with low probability of cracking in the case of screw twisting, which comprises a switch box body, a cable access point and screw connecting holes, wherein the cable access port is arranged at the front end of the switch box body, the screw connecting holes are arranged at four corners of the switch box body, each screw connecting hole comprises a threaded holeand at least two anti-cracking slots arranged adjacent to the threaded hole, the anti-cracking slots are consistent with the threaded hole in extension direction, the anti-cracking slots are distributed at equal intervals, and each anti-cracking slot is internally filled with a matched rubber strip. The beneficial effects are that the screw connecting hole does not crack when a tightened screw istwisted, thereby being capable of saving accessories of the switch box, not causing waste, and ensuring the assembling progress.

Description

technical field [0001] The invention belongs to the field of switch boxes of high-pressure cleaning machines, and in particular relates to a switch box whose screws are not easily cracked when screwed. Background technique [0002] The switch box of the high-pressure cleaner is provided with a screw connection hole for screwing the screw. By screwing the screw into the screw connection hole, it plays the role of assembly and fixation. However, the existing screw connection hole is easy to screw into the screw. When the tightened screw is unscrewed, the plastic screw connection hole is often cracked, causing the entire switch box to be scrapped, which is a serious waste, delays the work process, and slows down the work efficiency. Contents of the invention [0003] In view of this, the present invention aims to propose a switch box that is not easy to crack when the screw is turned, and the screw connection hole will not be cracked when the screw is tightened vigorously, wh...
