Abstract

The invention relates to a fastening device of protection cover plates of various appliances and particularly relates to a quick-dismounting appliance protection locking device, which solves the problems that the existing equipment protection device has the disadvantages of complex dismounting, time and energy wasting and having certain limitations. The device comprises a cover plate which can coordinate with the frame of the appliance; the creative point of the device is that one end of the cover plate is provided with a slot corresponding to the position of a screw hole on the frame of the appliance and the other end is provided with a rectangular orifice corresponding to the position of an unthreaded hole on the frame of the appliance; the upper and lower parts of the two sides of the rectangular orifice are respectively provided with a check plate. The device also comprises a locating bolt coordinated with the slot and the screw hole and an adjustable bolt coordinated with the rectangular orifice and the unthreaded hole; the bolt head of the adjustable bolt is a flat bolt head, a spring fixed in the inner side of the frame of the appliance is sheathed on a threaded rod. The device of the invention is characterized by the simple structure, being easy to be assembled and detached, and saving time, energy and space, besides, the device is suitable for any occasions and has good structural leak tightness and great promotional value.

Description

technical field [0001] The invention relates to various apparatus protective cover plate fixing devices, in particular to a new structure of a detachable apparatus protective locking device. Background technique [0002] The traditional method of fastening the protective cover of the instrument is as follows: directly rotate the bolt to fasten the protective cover at the position to be protected. This fixing method is troublesome to disassemble and requires a lot of work. Observation and process, etc.; another fixing method is to buckle the cover plate, hook it on one side, and fix it with elastic steel parts on the other side. Although this method is convenient, it is limited by the elasticity of elastic steel and the sealing performance It is not very good, especially in the operating conditions with severe vibration, the cover plate is easy to fall off, and in the small space, locking and dismounting require a certain amount of space, which has certain limitations. Cont...
