Description

Woodworking bench

Technical Field

The utility model belongs to carpenter's instrument, concretely relates to carpenter's work bench.

Background

During woodworking, the woodworking bench is used for supporting wood. In order to satisfy the height requirement of not using the user, perhaps satisfy different operation height requirements, carpenter's work bench's high design becomes adjustable, specifically realizes through the flexible of foot pole, and common extending structure is that inside and outside foot pole cup joints and cooperates elasticity to detain and stretch out and draw back and adjust, and elasticity is detained flexible regulation structure and is applied to square pipe type foot pole or pipe type foot pole, is not applicable to the half square base pin structure that the cross-section is the U type too.

The supporting strips are added between the working stool foot rods, the strength of the foot rods can be improved, the fixed straight rod type supporting strips cannot meet the folding requirements of the foot rods, and therefore the supporting strips adopt foldable connecting rod mechanisms in order to match the folding requirements of the working stool foot rods. In order to make the folded foot bars as flat as possible, the positions of the two folded foot bars have slight deviation, so the stay is required to be not only a simple connecting rod structure, but also be completely hidden in the foot bars after being folded.

In the work bench structure, the leg bar is usually a square tube or a round tube made of a metal material, and the leg bar is usually in an inclined support state. If the lower end of the foot rod is not processed, the contact part of the lower end of the foot rod and the ground is only provided with one point or one edge, the support is unstable, the sliding is easy to occur, and the potential safety hazard exists. And the lower end of the metal foot rod is directly contacted with the ground, so that the problems of abrasion and deformation are caused after the foot rod is used, and the service life of the foot rod is influenced. Therefore, a foot cover is usually fitted over the lower end of the foot bar for protection. The current common foot sleeve structure is a plastic sleeve matched with the lower end profile of a square tube type foot rod or a round tube type foot rod, for example, a hollow cuboid plastic sleeve with one open side, a hollow cylindrical sleeve with an open upper end and the like. The foot sleeve and the foot rod are matched mainly by friction between the foot sleeve and the foot rod, so that the foot sleeve and the foot rod have the problem of falling after being used for a long time, and are particularly easy to fall off when being collided accidentally. Moreover, the foot cover can only match with a complete square tube or a complete round tube, and cannot be used for a half-square pin rod with a U-shaped section.
