Abstract
A foot pedal switch of the utility model belongs to a mechanism for operating contacts of electric switches, which is especially suitable for foot operated switches for drivers of railway motor car which is electrically driven. The foot pedal switch is composed of a large-capacity microswitches with high efficiency and a transmission mechanism of pedals, and is a complete entire device for sealing. A pedal treads on a transmission top cap which is arranged below the pedal, a spring pad is driven to impel a pulling rod to enable a contacting spring pad and a wiring contact which are arranged in a microswitch to fit to connect a circuit. The utility model has the advantages of safe and reliable operation, use and switching, flexible action and long service life. The foot pedal switch far exceeds the requirement of 200, 000 times for the life of machinery of iron standard, and is widely applied to industries such as machine manufacture, traffic, metallurgy, mines, self control industries, etc.
Description
The utility model belongs to a kind of electrical switching contact operating mechanism, is specially adapted to do railway diesel-electric locomotive driver pedal control switch.
In prior art, the beeliner driver is to adopt general travel switch JLXK1-111 to install pedal additional and suppress reseting plate to assemble in order to the control locomotive stucco or the used foot switch of blowing a whistle.The easily stuck and damage of running part, electric switch part sealing is poor, is subject to humidity, and the influence of dust and Korrosionsmedium is not only lacked, and influence the safe and reliable of locomotive operation useful life.
The purpose of this utility model is a kind of shortcoming of existing in the prior art avoided of specialized designs, and has the self-contained foot switch of good seal performance, novelty safe and reliable to operation.
Embodiment of the present utility model is to select for use the sensitive switch of the big good seal performance of a kind of contact rating to be installed in the pedal transmission device of sealing, its concrete structure is that the end with pedal is installed on the housing with hinge, pedal is installed transmission top cap down, in the top cap axle sleeve that has a vertical shaft to be assemblied in the middle of the transmission top cap to be fixed in housing bottom, outside the cap axle sleeve of top, in the cap of transmission top stage clip is housed, the outer of transmission top cap and an end in contact of spring clip, the other end of spring clip contacts with the outer end of push rod, push rod is with little spring outward, contact spring coupling in the inner end of push rod and the sensitive switch is equipped with the wiring contact before contact spring.
In order to guarantee the interference-free and corrosion of sensitive switch and transmission mechanism, a seal cover board is installed on housing, sensitive switch and transmission mechanism are sealed in the housing, transmission top cap passes the cover plate position one sealing cup is installed.
Reliable and stable for pedal is connected with housing, a locking device is installed between pedal and seal cover board.
To be no more than the limit in order guaranteeing to step under the pedal, banking pin to be housed on seal cover board.
The utility model has the advantages that: whole foot switch is a packaged equipment, and good seal performance is moved safe safety, flexible movements, break-make is reliable, and long service life is considerably beyond 200,000 times requirement mechanical endurance of iron mark, the compact conformation of entire equipment is reasonable, volume is little, and is in light weight, and installation and maintenance are all very convenient, can be widely used in machine-building, industries such as traffic, metallurgy, mine and automatic control system.
Accompanying drawing is the structural representation of the utility model embodiment.
The drawing explanation: the 1-pedal, 2-transmission top cap, the 3-sealing cup, 4-connects hinge, 5-seal cover board, 6-rubber blanket, the 7-stage clip, 8-top cap axle sleeve, 9-spring clip, 10-little spring, 11-push rod, the 12-contact spring, 13-wiring contact, 14-housing, 15-locking device, 16-banking pin.
Embodiment:
Accompanying drawing is the structural representation of the utility model embodiment, it is that a end with pedal 1 is installed on the housing 14 with hinge 4, pedal is equipped with transmission top cap 2 for 1 time, having a vertical shaft to be assemblied in the middle of the transmission top cap 2 is fixed in the top cap axle sleeve 8 of housing 14 bottoms, outside top cap axle sleeve 8, in the transmission top cap 1 stage clip 7 is housed, the outer of transmission top cap 1 and an end in contact of spring clip 9, the other end of spring clip 9 contacts with the outer end of push rod 11, the push rod 11 outer little springs 10 that are with, contact spring 12 couplings in the inner end of push rod 11 and the sensitive switch are equipped with wiring contact 13 before contact spring 12.
For fear of the influence to mechanical driving device and sensitive switch such as dust and Korrosionsmedium, a seal cover board 5 is installed on housing 14, following lining rubber blanket 6, a sealing cup 3 is installed at the position that transmission top cap 2 passes seal cover board 5.
Between pedal 1 and seal cover board 5, locking device 15 is installed.Banking pin 16 is housed on seal cover board 5.
During use, the operator steps on pedal 1, it is descending in the cap axle sleeve 8 of top to depress transmission top cap 2, spring clip 9-end is depressed in the outer of transmission top cap 2, then revolving promotion push rod 11 on the other end of spring clip 9 moves in sensitive switch, promote coincideing of contact spring 12 and wiring contact 13, connect circuit.When the operator unclamps pedal 1, because the effect of stage clip 7 upwards sets back transmission top cap, spring clip 9 also no longer is subjected to the downward pressure of cap 2 outers, transmission top, because the effect of little spring 10 sets back push rod 11, also promote spring clip 9 simultaneously and set back.
