Abstract
The utility model discloses a simple pull spring tension detection device, which comprises a shaft seat, a pull hook, a scale, a bottom plate, a pull rope, a pulley and a weight. The shaft seat and the pulley are fixed at two ends of the bottom plate; the scale is placed on the bottom plate between the shaft seat and the pulley; a shaft is arranged on the shaft seat; the pull hook is S-shaped, one end is hooked with the shaft and the other end is hooked with a to-be-detected pull spring; the pull rope is suspended on the pulley, one end is hooked with the to-be-detected pull spring and the weight is suspended at the other end; a pointer is arranged at the connection end of the pull rope and the to-be-detected pull spring; and the size of the weight is determined according to different pull spring specifications. The device has the advantages that the structure is simple, the principle is simple and convenient, the cost is low, the tension value of the pull spring can be quickly detected whether in the standard range, and the production efficiency can be effectively improved.
Description
Technical field
The utility model relates to a kind of pick-up unit, relates in particular to a kind of simple and easy tension spring tension pick-up unit.
Background technology
Extension spring for conventional equipment as in function sofa opening device, for the error requirements of value of thrust, be not very high, a larger value range often.If the detecting instrument of the standard of use detects, the input of company is larger, and complicated operation causes the wasting of resources.
Summary of the invention
The utility model is for the deficiencies in the prior art, proposes a kind of simple in structurely, and cost is lower, can detect rapidly and accurately the whether simple and easy tension spring tension pick-up unit in critical field of pulling force of extension spring.
The utility model is achieved through the following technical solutions technical goal.
Simple and easy tension spring tension pick-up unit, its improvements are: comprise an axle bed, drag hook, rule, base plate, stay cord, pulley and counterweight; Described axle bed and pulley are fixed on the two ends of base plate; Described rule is placed on base plate, between an axle bed and pulley; Described axle bed is provided with fulcrum, and drag hook is S shape, and fulcrum is hooked in one end, and the other end hooks extension spring to be detected; Described stay cord hangs on pulley, and one end is hooked the extension spring other end to be detected and hung counterweight; The link of described stay cord and extension spring to be detected is provided with pointer.
In said structure, described drag hook and stay cord are steel wire.
In said structure, described drag hook, stay cord when work and the center of extension spring to be detected in sustained height.
The utility model compared with prior art, has following good effect:
The utility model utilizes tension spring tension F=KX(K: the elastic coefficient, X: spring deflection) principle make, simple in structure, cost is low, can fast detecting tension spring tension value whether in critical field, effectively enhance productivity.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
The utility model is described in further detail with reference to the accompanying drawings and in conjunction with the embodiments below.
Simple and easy tension spring tension pick-up unit shown in accompanying drawing, its improvements are: comprise an axle bed 1, drag hook 3, rule 4, base plate 5, stay cord 7, pulley 8 and counterweight 9; Axle bed 1 and pulley 8 are fixed on the two ends of base plate 5; Rule 4 is placed on base plate, between an axle bed 1 and pulley 8; Prop up axle bed 1 and be provided with fulcrum 2, drag hook 3 is S shape, and fulcrum 2 is hooked in one end, and the other end hooks extension spring to be detected; Stay cord 7 hangs on pulley 8, and one end is hooked the extension spring other end to be detected and hung counterweight 9; Stay cord 7 is provided with pointer 6 with the link of extension spring to be detected; Drag hook 3 and stay cord 7 are steel wire; Drag hook 3, stay cord 7 when work and the center of extension spring to be detected in sustained height; The weight of counterweight 9 is determined according to different extension spring specifications.
During operation, drag hook 3 is hooked in one end of extension spring, the other end hooks stay cord 7, when counterweight 9 moves downward while stopping, observing pointer 6 at rule 4, and as pointer 6, extension spring within the scope of assigned scale is qualified, and pointer 6 exceeds assigned scale scope, and extension spring is defective.
