Abstract

The invention relates to a telescopic circumferentially-closed protective device. The device comprises a base, telescopic support columns, compression springs, a protective body and a connecting disc; the protective body is composed of a plurality of round sleeves which are mutually connected and can freely telescope, the telescopic support columns are installed on the upper side and the lower side of the protective body, and the compression springs are installed in the corresponding telescopic support columns; the protective body and the telescopic support columns are installed between the base and the connecting disc; the base is fixedly connected with a part needing to be protected, and the telescopic support columns support the protective body and keeps the protective body at a certain protective position through the connecting disc under the action of the compression springs. According to the telescopic circumferentially-closed protective device, the structure is reasonable, installation is convenient, size changing of a space needing to be protected can be conveniently and rapidly achieved, and then solid substances in the space which regularly or irregularly changes within the axial length range are blocked and collected.

Description

technical field [0001] The invention relates to an enclosure guard, in particular to a retractable circumferential enclosure guard. Background technique [0002] We know that during the crankshaft production process, various operations such as drilling, milling, turning, grinding, polishing, etc. are required, and sometimes solid substances need to be collected in a protected space. However, there are irregular changes in the axial length range of the crankshaft. So far, there is no special protective device suitable for regular or irregular changes in the axial length range on the market. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art, and to provide a retractable and retractable device with reasonable structure, simple manufacture, convenient installation, which can block and collect solid matter in the changing space, and integrates safety and convenience. C...
