Abstract
The utility model discloses an area insurance trigger switch, include the shell and install at the inside trigger switch and insurance unit of shell, trigger switch includes position sleeve, rotor and torsional spring, be connected for rotating between rotor and the position sleeve, the both ends of torsional spring set up respectively on rotor and position sleeve, be provided with on the outer circumference of rotor and trigger the head, be provided with the safety groove on the terminal surface of rotor, the insurance unit includes the backing pin, the one end of backing pin stretches into in the safety groove, and the backing pin can be followed its axial and is broken away from the shell. Trigger switch structure of this area insurance, its stopping pin structure's setting, it has increased the safety guarantee for triggering the link to make.
Description
Technical field
This utility model relates to a kind of mechanical trigger switch structure, and particularly a kind of band insurance triggers field of switches.
Background technology
Triggering switch major part on the market is all that electricity triggers or simple button triggers, and fault rate is higher, and without
There are safety, are not suitable for some occasion particularly severe to reliability requirement.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, this utility model provides the insurance of a kind of band, triggering
Trigger switch reliably.
Technical scheme: for achieving the above object, band of the present utility model insurance triggers switch, including shell and be arranged on
The triggering switch of enclosure and security unit；Described triggering switch includes positioning sleeve, rotor and torsion spring, and described rotor is with fixed
For being rotationally connected between the set of position, the two ends of described torsion spring are separately positioned on rotor and positioning sleeve；On the excircle of described rotor
Being provided with trigger head, an end face of rotor is provided with safety groove, described security unit includes backing pin, one end of described backing pin
Stretch in described safety groove, and backing pin can be axially disengaging described shell along it.The setting of this backing pin structure makes this trigger architecture more
The safety added, and add controllability for its trigger action, compensate for the dangerous uncontrollable drawback of common trigger architecture.
Further, described security unit also includes spring, gland and insert-pull pin, and described backing pin is with the shaft shoulder, described
Spring is pressed between the shaft shoulder of described backing pin and described positioning sleeve, and described backing pin is pressed in described shell by described gland, described
Gland is fixed on shell by insert-pull pin.
Further, the described switch that triggers also includes auxiliary positioning pin, and described positioning sleeve is provided with the first auxiliary positioning
Hole, described rotor is provided with the second auxiliary positioning hole, and during assembling, described auxiliary positioning pin can penetrate the first auxiliary simultaneously
Hole, location and the second auxiliary positioning hole limit relatively rotating between rotor and positioning sleeve.
Beneficial effect: a kind of band insurance of the present utility model triggers switch, the design of unique backing pin structure, makes this triggering
Structure is the safest, and adds controllability for its trigger action, compensate for the dangerous uncontrollable fraud of common trigger architecture
End.
Accompanying drawing explanation
Accompanying drawing 1 triggers the structure chart of switch for band insurance；
Accompanying drawing 2 is the structure chart triggering switch.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
A kind of band insurance as described in Figure 1 triggers switch, including shell 1 and be arranged on the triggering within shell 1 and open
Pass 2 and security unit 3；As shown in Figure 2, the described switch 2 that triggers includes positioning sleeve 21, rotor 22 and torsion spring 23, described turn
For being rotationally connected between son 22 and positioning sleeve 21, the two ends of described torsion spring 23 are separately positioned on rotor 22 and positioning sleeve 21；Institute
State and on the excircle of rotor 22, be provided with trigger head 24, an end face of rotor 22 is provided with safety groove, described security unit 3
Including backing pin 31, one end of described backing pin 31 is stretched in described safety groove, and backing pin 31 can be axially disengaging described shell 1 along it.
Described security unit 3 also includes spring 32, gland 33 and insert-pull pin 34, and described backing pin 31 is with the shaft shoulder, described
The chien shih backing pin 31 of the shaft shoulder and described positioning sleeve 21 that spring 32 is pressed in described backing pin 31 has axially deviates from becoming of shell 1 along it
Gesture, described backing pin 31 is pressed in described shell 1 by described gland 33, and gland 33 is fixed on shell 1 by described insert-pull pin 34.
The described switch 2 that triggers also includes auxiliary positioning pin 25, and described positioning sleeve 21 is provided with the first auxiliary positioning hole, institute
Stating and be provided with the second auxiliary positioning hole on rotor 22, during assembling, described auxiliary positioning pin 25 can penetrate the first auxiliary simultaneously
Hole, location and the second auxiliary positioning hole limit relatively rotating between rotor 22 and positioning sleeve 21.One end of backing pin 31 is being stretched
After entering in described safety groove, extract positioning needle 25.Neglect, during being so possible to prevent assembling, the danger caused.
A kind of band insurance of the present utility model triggers switch, the design of unique backing pin structure, makes this trigger architecture more
Safety, and add controllability for its trigger action, compensate for the dangerous uncontrollable drawback of common trigger architecture.
The above is only preferred implementation of the present utility model, it should be pointed out that: for the common skill of the art
For art personnel, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these improve and
Retouching also should be regarded as protection domain of the present utility model.
