Abstract
The utility model relates to an incorrect operation prevention and safety apparatus for a foot pedal switch. The utility model is mainly characterized in that a switch body is provided with a protecting sheath, and a foot pedal is provided with an incorrect operation prevention mechanism. The structural design of the utility model is simple, forthright, practical, and reliable. The utility model has the advantages that the accident threat and the incorrect operation are prevented on a structure, the operational safety of the foot pedal switch is effectively enhanced, and the utility model is the practical and the effective improved design.
Description
Technical field
The utility model relates to a kind of false action-proof and safety device of foot switch.
Background technology
Foot switch is an operation control assembly commonly used in the processing industry, generally uses with sale of finished goods.But, all unshielded device of common foot switch.Find in the practice, due to factors such as operator's fatigue, subconsciousness, easily produce misoperation or security incident etc.
Summary of the invention
The purpose of this utility model is for fear of above-mentioned misoperation and prevents security incident hidden danger and disclose a kind of false action-proof and safety device of foot switch.For reaching this purpose, following technical scheme is proposed: be to be shaped on protective cover on the foot switch and on pedal, to be shaped on false action-proof mechanism; Wherein, false action-proof mechanism comprises scotch, torsion spring and a roller, and scotch is placed through the hole on the pedal and connects it with pivot pin, scotch bottom device one roller with it; There is an end to be overlapped in pedal around the home and the other end is overlapped in the torsion spring of scotch on the axle of scotch and pedal pin joint.
The utility model simple structural design, practicality, reliable have prevented accident potential and have avoided misoperation from structure, have solved the processing safety of foot switch effectively, can yet be regarded as a kind of practicality and effectively improve design.
Description of drawings
Fig. 1 is the vertical profile TV structure schematic diagram of a kind of embodiment.
Fig. 2 is the structure enlarged diagram of false action-proof mechanism among the embodiment.
Embodiment
Be shaped on hull shape protective cover 4 on the switch body 1, the pedal 2 in its switch is shaped on false action-proof mechanism; This mechanism comprises scotch 3, torsion spring 5, roller 6, and wherein, scotch is placed through the perforate on the pedal and connects with pivot pin with it, has the one end to be overlapped in pedal on this around the home and the other end is overlapped in the torsion spring of scotch.Because the elastic force effect of torsion spring makes scotch prop up pedal all the time and unlikely malfunction.And have only when normally operating, pedal can move when stepping on scotch forward.Otherwise scotch makes it reset under the torsion spring effect and props up pedal and prevented misoperation.
Claims (3)
1, a kind of foot switch false action-proof and safety device is characterized in that being shaped on protective cover and be shaped on false action-proof mechanism on pedals on the foot switch body.
2, by described false action-proof of claim 1 and safety device, it is characterized in that false action-proof mechanism comprises stop, torsion spring and a roller, wherein, scotch is placed through the hole on the pedal and connects it with pivot pin, scotch bottom device one roller with it.
3, by claim 1,2 described false action-proof and safety devices, it is characterized in that scotch and pedal pin joint spool on have the one end to be overlapped in pedal around the home and the other end is overlapped in the torsion spring of scotch.
