Abstract
The utility model relates to a plastic part of thing to sit on especially relates to a plastic part who is used for the thing to sit on as the mat. A plastic part, includes the body, the body edge is the bellying, and central part is sunken, and its central point puts and sets up the centre bore, body edge inner wall department is equipped with the crack control annular groove. The transmission of radial force to the bellying has been blocked in the existence of crack control annular groove, the too big problem that leads to the fracture of atress when having avoided the installation.
Description
Technical field
This utility model relates to a kind of working of plastics for thing to sit on, particularly relates to a kind of working of plastics for thing to sit on as mat.
Background technology
The working of plastics for chair in the market, its basic structure is body, and body edges is provided with lobe, and center offers centre bore, in order to install screw etc. But, existing working of plastics is when installing the parts such as screw, owing to plastics itself can deform, when then installing, body central hole adnexa has bigger pressure, and this pressure can become stress radially, then leads to working of plastics radially cracking. So how to avoid this problem, the problem that inventor to solve just.
Summary of the invention
This utility model solves the problem that working of plastics in the market easily ftractures when mounted, it is provided that the working of plastics of a kind of simple and practical crack resistence, and its concrete technical scheme is as follows:
A kind of working of plastics, including body, described body edges is lobe, and core caves in, and its center arranges centre bore, and described body edges inwall place is provided with anticracking annular groove. The existence of anticracking annular groove, blocked the radial force transmission to lobe, it is to avoid the stress excessive problem causing cracking when installing.
