Description
Technical field
The utility model is specifically related to a kind of key-lifting switch.
Background technique
Currently, beeliner, electric locomotive, harmonious locomotive, urban rail subway and various industrial and mining locomotives, key-lifting switch
For group core component key-lifting switch using key switch, contact is bareing, poor contact easily occurs, while easily violating card event
Barrier rate is high, and overall volume is big and clumsy.And there is also structure is complicated, volume is big, performance is unstable, failure for existing key-lifting switch
The high defect of rate.
Summary of the invention
The purpose of the utility model is to overcome the defect of the prior art, provide a kind of structure it is simple, it is stable and reliable for performance,
Low, the small in size key-lifting switch of failure rate.
To achieve the above object, the utility model uses a kind of key-lifting switch, including installation panel, multiple settings installing
Switch block on panel, the lock-switch being arranged on installation panel, on the lower end surface of the installation panel there are four settings
The installation column of rectangular array distribution, the switch block include the bracket being arranged in installation panel, are rotatably arranged on
Push-key handle on bracket, is arranged in the first cam the first cam for being rotatably arranged on bracket and matching with push-key handle
Torsional spring between bracket, the second cam being linked with push-key handle, be rotatably arranged on push-key handle and with it is second convex
Microswitch on bracket is set at the third cam of wheel linkage setting, corresponding third cam, the push-key handle it is upper
End extends in the outside of installation panel, and the third cam acts with push-key handle and can push the contact of microswitch, real
Existing microswitch is switched on or switched off.
The beneficial effect of above structure is: the key-lifting switch is with structure is simple, stable and reliable for performance, failure rate is low, body
The small advantage of product, and microswitch uses all-sealed structure, degree of protection IP60, has a sand-proof, non-maintaining feature, therefore
Barrier rate is low；Its push-key handle is suppressed using oil resistant, high temperature resistant, fire-retardant nylon material, has the characteristics that small and exquisite exquisiteness, can
The plate switching group effectively solved on beeliner, electric locomotive, harmonious locomotive, urban rail subway and various industrial and mining locomotives is deposited
Poor contact and easily violate card the problems such as, reduce failure rate, safe and reliable product is provided for railway transportation.
Particularly, arc convex portion, first cam are provided at corresponding first cam on the push-key handle
On be provided with arc groove, the arc convex portion acts and can slide in arc groove with push-key handle, constitutes push-key handle
With being linked for the first cam.It is provided with the arc convex portion matched with arc groove on push-key handle, ensure that push-key
Handle can be reliably driven with the first cam, avoid push-key handle that Caton phenomenon occurs.
Particularly, it is respectively arranged with mounting hole on the both ends of the bracket, is provided with and installs in the mounting hole
The screw that panel is connected.Bracket is fixed by screws on installation panel, is easy to implement the modular assembly of switch block, has
Conducive to the assembly efficiency for improving the key-lifting switch.
