Embodiment 1

[0025] Such as Figure 1 to Figure 4 As shown, the tension measurement tool of the present invention, which can also be called a pull-pan measurement tool, mainly includes a pull positioning mechanism 2 , a force applying mechanism 3 and a switching mechanism 4 .

[0026] Preferably, the present invention also includes a body 1 , which is mainly used for installing the pull positioning mechanism 2 , the force applying mechanism 3 and the switching mechanism 4 .

[0027] The pull positioning mechanism 2 can pull the workpiece to be tested, and the workpiece to be tested will be described below with a zipper slider as an example. The pull positioning mechanism 2 mainly includes a first positioning portion 21 and a second positioning portion 22 which are arranged correspondingly. The corresponding ends of the first positioning portion 21 and the second positioning portion 22 are adapted to the pull position of the workpiece to be measured respectively. In short, the opposite end...

Embodiment 2

[0030] The force applying mechanism 3 mainly applies the opposing pulling force to the opposing pulling positioning mechanism 2 . The biasing mechanism 3 mainly includes a biasing spring 31 that can expand and contract freely. The elastic force generated by the two free ends of the biasing spring 31 can be applied to the first positioning portion 21 and the second positioning portion 22 correspondingly.

[0031] The biasing mechanism 3 includes a stretchable biasing spring 31 , and the two free ends of the biasing spring 31 directly or indirectly bear against the first positioning portion 21 and the second positioning portion 22 .

[0032] Preferably, the lower free end of the biasing spring 31 is disposed on the body 1 , or is sleeved on a spring pin 311 protruding from the body 1 . The upper free end of the biasing spring 31 is connected to the first positioning portion 21 through a cap 32 . Specifically, one end of the cap 32 is cap-shaped and sleeved on the upper free en...

Embodiment 3

[0035] The switching mechanism 4 mainly switches between the force application state and the force withdrawal state of the force application mechanism 3 . The switching mechanism 4 includes a limiting portion 41 , and the limiting portion 41 is movably connected to the force applying mechanism 3 in a detachable manner.

[0036] Preferably, the switching mechanism 4 further includes a pressing portion 44 , and the limiting portion 41 includes a limiting rod 42 and a limiting spring 43 . A limiting hole 321 is opened on the cap 32 . The pressing part 44 pushes against one end of the limit rod 42, and the other end of the limit rod 42 protrudes to set a limit part 41. The limit part 41 can adopt a structure such as a pin shape or a cap shape, and the limit part 41 passes through a limit spring. 43 can freely expand and contract in the limiting hole 321 . The limiting rod 42 is provided on the main body 1 in a swingable manner around the fulcrum 11 through the fulcrum 11 on the ...

Abstract

The invention discloses a pull force measurement tool which comprises an opposite pull locating mechanism for oppositely pulling a to-be-measured workpiece, a force application mechanism for applying an opposite pull force on the opposite pull locating mechanism, and a switching mechanism for switching the force application state and the force removal state of the force application mechanism. When the pull force measurement tool is used in a test, the to-be-measured workpiece is placed on the opposite pull locating mechanism, and the force application mechanism applies a test force on the to-be-measured workpiece through the switching mechanism. The pull force measurement tool is simple in structure and easy to carry, the requirement on the environment is not high, and the pull force measurement tool can be stored on a production field for a long period of time. Therefore, whether the produced to-be-measured workpiece meets the requirement is timely and conveniently tested in the production process.

Description

technical field [0001] The invention relates to a tension measuring tool, in particular to a simple tension measuring tool. Background technique [0002] The present production site tests the pulling force and binding force of the zipper with instruments, although the values ​​of the pulling force and binding force of the tested zipper head can be measured. However, the volume and quality of the instrument are relatively large, it is not easy to move, and it has high requirements on the environment, so it is not easy to store for a long time at the production site. In the production process, it is often necessary to test whether the produced slider can meet the requirements in time, so it is necessary to develop a simple test tool that is also easy to carry. Contents of the invention [0003] In view of this, the object of the present invention is to provide a tension measuring tool with a simplified structure. [0004] In order to achieve the above object, the solution ...
