Abstract
A misoperation-preventive knob protective cover is composed of a shell and magnets. The misoperation-preventive knob protective cover is characterized in that the shell is a pentahedron composed of a faceplate (1) and side plates (2), a cover with an opening on one face is formed on the shell, and the magnets (3) are arranged at four corners of the opening face. Warning words like 'No Operating' are printed on the faceplate (1), and when in use, the misoperation-preventive knob protective cover is covered on a knob (or button) of a power control cabinet to prevent misoperation; and the magnets are arranged at the four corners, so that the misoperation-preventive knob protective cover can be tightly adsorbed on the control cabinet without being blown off by wind or causing troubles due to mistaken touching. The misoperation-preventive knob protective cover is simple in production process, low in cost and convenient to mount.
Description
Technical field
The utility model relates to a kind of a kind of protective cover that prevents the knob on the misoperation electric control cabinet (or button) and make.
Background technology
Knob on the electric control cabinet (or button) is used for control switch deciliter, in case the misoperation meeting causes serious consequence, the knob at No switching on hangs indication plate usually, but because being blown off easily, or mistake bumps and causes the accident, and therefore, further solution need be arranged.
The utility model content
The purpose of this utility model overcomes the deficiencies in the prior art exactly and designs a kind of misoperation knob protective cover that prevents.
For achieving the above object; the technical solution adopted in the utility model is: prevent misoperation knob protective cover, be made up of housing, magnet, it is characterized in that: housing is formed pentahedron by panel (1) and side plate (2); be formed with the cover of an opening, at opening surface four jiaos magnet (3) arranged.
Be printed on " quiescing " or caution printed words such as " someone work and forbids to operate " at panel (1), during use the utility model covered on the knob (or button) on the electric control cabinet, prevent misoperation, because four jiaos have magnet, can tightly be adsorbed on the control cubicle and can not come off.
The utility model beneficial effect compared to existing technology is:
Can not be blown off, or bump by mistake and cause thing, production technology is simple, and cost is low, and is easy for installation.
