Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, illustrated embodiment is served only for explaining this reality
With novel, it is not intended to limit the scope of the utility model.
As shown in figs 1 to 6, a kind of quick test fixture of self-tightening type band pulling force of the present embodiment, including pedestal 1, coiling
Stick 2 and limiter 3 offer the laterally through slot 11 of setting and open at both ends in the pedestal 1, and 1 upper end of pedestal offers
The opening 12 being connected to inside the through slot 11, the adaptation of wire rod 2 are plugged in the through slot 11, and the limiter 3 is pacified
On the pedestal 1 and close to 12 setting of opening；4 both ends of band bypass after the wire rod 2 from the opening
12 stretch out and are clamped the extension of the band 4 by limiter 3.
Wherein, the limiter 3 can be clamped band extension using clip etc., and the clamping end of clip is reserved with one
Fixed space makes band that will not be occurred drawing motionless situation while clamp.
It should be noted that the present embodiment pulls band to be tested by collet, other tools can also be passed through
To be tested to move band.
The present embodiment passes through the cooperation of wire rod, through slot and limiter, is wound around band on wire rod, then up
Lift wire rod during, it is ensured that initial upward movement process band will not occur slide and misplace, when band by
Wire rod further has compressed between wire rod and pedestal through slot along pedestal through slot upward sliding when external force moves upwards
Gap, to realize band self-tightening process.The tooling of the present embodiment is bilateral symmetry formula structure, in direction of pull and sample
Heart line is conllinear, left and right sides uniform force, and there are four fixation holes for pedestal tool, the problems such as will not rotating.
As shown in Figure 1-Figure 3, the embodiment of the present invention limiter 3 is at least a pair of, and the limiter 3 of each pair of two is right
Claim the two sides that the opening 12 is set, and is connected to the two sides of 4 extension 41 of band respectively.Limiter 3 can select
With elastic construction, pressure to 4 extension of band is realized to realize that the part for stretching out pedestal 1 to band 4 applies elastic acting force
Tightly, the setting of at least a pair of of limiter, may be implemented to one or more bands while detecting.
As shown in figure 4, a concrete scheme of the embodiment of the present invention limiter 3 is, limiter 3 includes bracket, slide bar
31 and elastic component 32, described bracket one end be fixed on the pedestal 1, the other end offers slide opening 36, and the slide bar 31 is worn
It is slided in the slide opening 36 and along the direction perpendicular to the opening 12, it is close that the elastic component 32 is set in the slide bar 31
In a part of the opening 12, and both ends are connect with the bracket and the slide bar 31 respectively.Pass through setting slide bar and elasticity
Part makes slide bar and band extension Elastic Contact, and clamping force can be adjusted.31 level of slide bar is threaded through slide opening
It is slided in 36 and along the direction level perpendicular to the opening 12, the distance that slide bar 31 slides in slide opening 36 is exactly elastic component bullet
Property deformation length, the limiter 3 in 12 two sides that are open is symmetrical arranged, when use, in the opposite direction it is mobile make them it
Between reserve certain gap, then the extension of band 4 is pierced by upwards from the gap, then unclamp limiter 3,
The compression to band extension is realized by elastic component elastic deformation.
The structures such as the optional spring of elastic component 32 of the present embodiment, rubber tube.The difficulty selected in view of elastic strength and material
Easy degree, it is preferred to use spring.
Wherein, the bracket can select the structure for arbitrarily capableing of supporting slider 31, and inverted L can be used for example
Type bracket or vertical structure bracket directly adopt slab construction etc..
As Figure 1-Figure 4, the embodiment of the present invention slide bar 31 is equipped with gag lever post 33 close to one end of the opening 12,
32 both ends of elastic component are connect with the bracket and the gag lever post 33 respectively, and the gag lever post 33 is parallel with the through slot 11
Arrangement and the top for being located at the opening 12.The setting of gag lever post can increase the contact area with band extension, make to limit
Position bar is to the more uniform stabilization of the active force of band.Gag lever post 33 is horizontally disposed, can be realized by gag lever post to band extension
Divide effective compression of two sides.
