Abstract

The utility model relates to a pedal switch, which belongs to a control device of a pedal electric appliance of a vehicle or a machine tool. The dual-cavity structure is used for effectively sealing the microswitch; the swing rod type power transmission mode is used for changing the switching operation of the microswitch into transversal direction, and the integral height can be reduced effectively; meanwhile, the screw thread regulation mode is adopted to carry out the micromotion regulation to the stroke of the switch, and the switch is locked by screws after adjusted. The switch has the advantages of reliable operation, long service life, good dustproof, waterproof and oilproof properties, and the utility model can completely satisfy the operating requirements of various vehicles and machine tools.

Description

Foot switch

The utility model foot switch is a kind of pedal control switch that is used for control apparatus equipment such as diesel locomotive, electric locomotive, lathe.

Pedal control switch is a kind of electrical equipment control device of handled easily, can be very complicated owing to the running environment of railway locomotive, condition is also very poor, particularly the reliability of controlling parts becomes more important, as long as it is go out a bit malfunctioning or out of control locomotive machine halt trouble that gently then causes, heavy then cause the major accident of car crash; Part lathe operational environment is more special in addition, need to satisfy protection against the tide, waterproof, prevent the wet goods requirement, and general foot switch can not satisfy these requirements, necessaryly for this reason develops a kind of novel foot switch.

The purpose of the utility model foot switch is exactly a kind of foot switch that designs at the specific (special) requirements of locomotive and lathe, and it adopts sealed construction, can satisfy the instructions for use of locomotive, lathe fully, and easy for installation, and useful life 200,000 times is non-maintaining.

According to the technology implementation scheme that the purpose of this utility model proposed be: foot switch is designed to dual-chamber structure, allows sensitive switch installation room and return spring chamber separate, can reduce both cross pollutions like this, it is totally-enclosed to make things convenient for the sensitive switch chamber to form; Two Room transmission of power adopt the oscillating rod type design, not only satisfy the design instructions for use, and simple in structure; Helical structure is adopted in the sensitive switch adjustment, and is easy to adjust, can prevent to damage sensitive switch; For convenient foot-operated and anti-skidding and reach good looking appearance, the foot-operated face of lid adopts inclined-plane band straight burr structure.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1 is the utility model structural representation.Accompanying drawing shows being made up of lid 1 and pedestal 2 of the utility model employing, and the centre is connected to form monolithic construction with pin 3.Lid 1 cover plate 4 and left-hand thread rim of the mouth 20 by inclined-plane band straight burr constitutes.Have one to protrude platform 5 at cover plate 4 rearward end inner faces, platform 5 tightens the fine setting seat 6 that is connected with a threaded shank, on the screw rod of fine setting seat 6, be screwed with a bowl-type trimming piece 7, one lock-screw 8 is housed again on the end face of bowl-type trimming piece 7, after trimming piece 7 is adjusted the position, by 8 lockings of the lock-screw on the trimming piece 7, one return spring 9 also is housed in the bowl-type in bowl-type trimming piece 7, pedestal 2 then includes sensitive switch annular seal space 10 and is used to install the cavity 11 of bowl-type trimming piece, and constitute dual-chamber structure thus, sensitive switch 12 is installed in annular seal space 10, and be fixed on the pedestal 2 by screw 13, above sensitive switch 12, have one by the fastening seal cover 21 of screw, the one auxiliary return system that is made of spring 15 and return bar 16 also is housed on the rib 14 of pedestal 2 simultaneously, and the switch motion of sensitive switch 12 is by hanging over the swing reed 18 on the pedestal pole 17, pass over by trimming piece 7, the fork interlock transferring structure of carrying out, head at annular seal space 10 also is equipped with a closed lead attachment plug 19, is used for lead is drawn in foot switch.

During practical application,, will drive bowl-type trimming piece 7 by platform base and move downward, and bowl-type fine setting 7 will drive reed 18 and do oscillating motion, and the motion break-in will be delivered to sensitive switch, sensitive switch 12 is moved when pin slams cover plate 4 rear portions when moving downward.After pin unclamps, bowl-type trimming piece 7 will rise under the effect of return spring 9 and reset, and reed 18 also will be at acting in conjunction lower swing return spring 15 and return bar 16 and sensitive switch.

The utility model has adopted bicavate swing sensitive switch structure, break-in by action force, successfully horizontal of sensitive switch is being put, thereby not only reduced the height of foot switch, and improved the air-proof condition of sensitive switch widely, made foot switch really reach dustproof, waterproof, moistureproof performance, the needs of the operation of satisfying locomotive and all kinds of lathes that can be real, and long service life can reach non-maintaining effect 200,000 times, has the value of applying.
