Bulb can not be protected.Therefore need to detect the quality of R type locking pins, especially R types locking pin is locked from it
Whether tight position is detected to the pulling force of coupled position, normal with elasticity at detection hunchback.But detection of the prior art
Class device is not particularly suited for the detection to R type locking pins.
Utility model content
The purpose of this utility model is to provide a kind of R types locking pin pull force calculation instrument, and the utility model is simple in construction, behaviour
Facilitate, pull force calculation efficiently, accurately can be carried out to R types locking pin.
In order to solve the above technical problems, the technical solution adopted in the utility model is as follows：
A kind of R types locking pin pull force calculation instrument, including tensiometer, tensiometer include coupler body, draw-bar donamometer and both ends point
Not Lian Jie coupler body and draw-bar donamometer spring, described detecting instrument also includes interior rotating cylinder and outer sleeve, and interior rotating cylinder outer wall is provided with outer
Screw thread, outer sleeve inwall are provided with internal thread, interior rotating cylinder and outer sleeve threaded connection, and tensiometer passes through interior rotating cylinder and draw-bar donamometer and hook
Body is leaked outside interior rotating cylinder cruelly respectively.
Preferably, the draw-bar donamometer is fixedly connected by bearing with interior rotating cylinder inner wall of end, in bearing case and interior rotating cylinder
Wall is connected, and bearing inner casing is connected with draw-bar donamometer.
Preferably, the coupler body is arranged on the sliding block being connected with spring, and sliding block outer cover is provided with lasso, and lasso both sides are set
There is an otic placode, relative axis is arranged with boss in interior rotating cylinder inwall, and gag lever post one end axially arranged along interior rotating cylinder is consolidated with boss
Fixed connection, the other end pass through otic placode.
Preferably, described interior rotating cylinder passes outer sleeve close to one end of draw-bar donamometer and hand screw plate is installed with both sides.
Preferably, described bearing is thrust bearing.
Preferably, described interior rotating cylinder is made up of two semicircular cylinder radial direction clampings.
The utility model application method is as follows：The corresponding interior rotating cylinder of R type locking pins specification selection detected as needed（It is interior
The internal diameter of rotating cylinder is less than the arc tips width of R type locking pins）, then coupler body is connected with the arc tips of R type locking pins, passed through
Rotating cylinder in the rotation of hand screw plate so that interior rotating cylinder outwards screws out outer sleeve close to the end of draw-bar donamometer.Due to the setting of thrust bearing,
Circumferentially rotating for interior rotating cylinder will not drive draw-bar donamometer and spring pivotal, only can be by spring elongation, the spring band movable slider after stretching
R type locking pins are pulled with coupler body, final pull force calculation result can be shown by draw-bar donamometer.In order to prevent spring to sliding block
Force inequality tumble when causing sliding block to be moved in interior rotating cylinder the phenomenon of faceplate, the utility model uses gag lever post to cunning
Spacing when block moves, gag lever post and lasso rotate with the rotating cylinder of inner sleeve, do not have blocking effect to sliding block.
Interior rotating cylinder can also use splicing structure, convenient dismounting maintenance.
The utility model compared with prior art, has the following advantages that：The utility model is simple in construction, can efficiently, essence
Pull force calculation accurately is carried out to R types locking pin, compensate for deficiency of the prior art, operating efficiency is improved, saves manpower, reach
To conveniently purpose.
Brief description of the drawings
Fig. 1 is the structural representation of R type locking pin pull force calculation instruments in embodiment；
Fig. 2 is the profile that R types locking pin connects with the locking of insulator bowl head in the prior art.
Embodiment
In order that the purpose of this utility model, technical scheme and advantage are more clearly understood, below in conjunction with accompanying drawing and implementation
Example, the utility model is further elaborated.It should be appreciated that specific embodiment described herein is only explaining
The utility model, it is not used to limit the utility model.
As shown in figure 1, a kind of R types locking pin pull force calculation instrument, including tensiometer, tensiometer include being arranged at sliding block 5
On coupler body 6, draw-bar donamometer 3 and the spring 4 of both ends difference connection sliding block 5 and draw-bar donamometer 3, the detecting instrument also includes interior turn
Cylinder 2 and outer sleeve 1, the interior outer wall of rotating cylinder 2 are provided with external screw thread, and the inwall of outer sleeve 1 is provided with internal thread, interior rotating cylinder 2 and outer sleeve 1 screw thread
Connection, tensiometer are leaked outside interior rotating cylinder cruelly respectively through interior rotating cylinder 2 and draw-bar donamometer 3 and coupler body 6, and interior rotating cylinder 2 is close to draw-bar donamometer
