Description
Technical field
It the utility model is related to spring technical field, the electric switch spring of more particularly to a kind of adjustable-tightness.
Background technology
The effect of spring is to provide restoring force in the switching mechanism inside electric switch, when switch runs into high pressure, electric leakage
Situations such as, power is automatically provided by the spring on switching mechanism, is cut off the electricity supply, so spring there must be enough elastic force
It can just respond rapidly to；On existing switching mechanism spring installation in band hook spring be more commonly used；Because installation rate is fast, only
The hook body of both ends of the spring is needed to hook respectively into two holes of spring coupling plate；But this connected mode, spring once connect
After upper, the elastic of spring can not be adjusted, and the feel for stirring electric switch is determined in itself by spring completely；Because each spring manufactures
During have differences influence electric switch use feel.
Utility model content
The defects of the purpose of this utility model is to be directed to prior art and deficiency, there is provided a kind of simple in construction, design is closed
Reason, the electric switch spring of adjustable-tightness easy to use.
To achieve the above object, the technical solution adopted in the utility model is：
A kind of electric switch spring of adjustable-tightness described in the utility model, it includes spring body；The bullet
The both ends of spring body are provided with straight connecting pole；Circular sleeve is cased with the straight connecting pole；The circular sleeve with it is direct-connected
Post is connect mutually to be fixedly connected；Set external screw thread is provided with the lateral wall of the circular sleeve.
Further, the luminal perfusion of the circular sleeve has glue；The circular sleeve is fixed on direct-connected by glue
Connect on post.
Further, the end of the straight connecting pole, which is provided with, takes the lead.
Further, the madial wall of circular sleeve is provided with set internal thread.
Further, the spring body is rectangular coil spring.
After said structure, the utility model has the beneficial effect that：A kind of adjustable-tightness described in the utility model
Electric switch spring, the both ends of spring body are provided with straight connecting pole；Circular sleeve is cased with straight connecting pole；Circular sleeve
Mutually it is fixedly connected with straight connecting pole；Set external screw thread is provided with the lateral wall of circular sleeve.When using the utility model, two pieces
One of in spring coupling plate to be fixed on electric switch, another piece of spring coupling plate control apparatus switch connection is with disconnecting；
Through hole is offered on two pieces of spring coupling plates, spring body is arranged between two pieces of spring coupling plates, spring body both ends
Circular sleeve is each passed through two through hole rear threads and is connected with nut；Change the tensile elongation of spring body by rotating nut,
Change the pulling force suffered by two spring coupling plates, so as to change the feel of electric switch, spring body still can after loading onto
Enough it is adjusted, until the pulling force suffered by spring coupling plate is improved the use feel of electric switch to suitable position.

Embodiment
The utility model is further described below in conjunction with the accompanying drawings.
As shown in Fig. 1 to 5, a kind of electric switch spring of adjustable-tightness described in the utility model, it includes bullet
Spring body 1；The both ends of the spring body 1 are provided with straight connecting pole 101；Circular set is cased with the straight connecting pole 101
Cylinder 2；The circular sleeve 2 is fixedly connected with the straight phase of connecting pole 101；The outer spiral shell of set is provided with the lateral wall of the circular sleeve 2
Line 202；One of in two pieces of spring coupling plates 4 to be fixed on electric switch, another piece of spring coupling plate 4 opens control apparatus
Close connecting and disconnecting；Through hole 401 is offered on two pieces of spring coupling plates 4, spring body 1 is arranged on two pieces of spring coupling plates 4
Between, the circular sleeve 2 at the both ends of spring body 1 is each passed through two rear threads of through hole 401 and is connected with nut 3；By rotating spiral shell
Mother 3 changes the tensile elongation of spring body 1, changes the pulling force suffered by two spring coupling plates 4, so as to change electric switch
Feel, spring body 1 can still be adjusted after loading onto, until the pulling force suffered by spring coupling plate 4 is to suitable position,
It is improved the use feel of electric switch.
As a kind of preferred embodiment of the present utility model, the luminal perfusion of the circular sleeve 2 has glue 5；The circle
Sleeve 2 is fixed on straight connecting pole 101 by glue 5, fixes circular sleeve 2 using glue 5, assembling speed is fast, and cost is low.
As a kind of preferred embodiment of the present utility model, the end of the straight connecting pole 101 is provided with the 101a that takes the lead；Glue
Water 5 takes the lead 101a cards master between glue 5 and circular sleeve 2 after shaping, effects of the 101a equivalent to built-in fitting of taking the lead now,
Circular sleeve 2 is set preferably to be fixed on spring body 1.
