Description

Elastic material deformation detection device

Technical Field

The utility model relates to the technical field of detection devices, in particular to an elastic material deformation detection device.

Background

With the development of science and technology, the elastic material with reversible deformation is more and more widely applied. For example, it can be applied to a door and window pad of a washing machine, an intake/guide duct of a washing machine, and the like. Reversibly deformable elastic materials refer to: the elastic material can be deformed greatly by applying a small external force, and the deformation can be recovered after the external force is removed, for example, the reversibly deformable elastic material can be vulcanized rubber, thermoplastic elastomer (TPE), and the like.

However, both vulcanized rubber and TPE products suffer from aging, gradual loss of elasticity, and permanent deformation (i.e., the size of the product cannot be restored to its original state after the external force is removed, and there is residual deformation) during processing, storage or use, which affects the function and service life of the product. For example, the gasket of the washing machine is affected by external environmental factors such that the elasticity of the gasket becomes small, and thus, when the door or window is opened or closed, the damping and sealing effects of the gasket become poor, and the noise of the machine becomes large. Therefore, enterprises will often perform compression deformation testing and tension deformation testing on reversibly deformable elastic materials.

However, the compression set tests currently used are all based on the current "GB _ T7759.1-2015 determination of compression set for vulcanized or thermoplastic rubbers part 1: determination of compression set of vulcanized rubber or thermoplastic rubber under Normal temperature and high temperature conditions GB/T7759.2-2014 part 2: the special compression device in the low-temperature condition has the disadvantages of complex structure, higher detection cost and low detection efficiency.

In order to improve the accuracy of the graduated scale, the stretching or compressing direction of the elastic material 200 is parallel to the extending direction of the guide member 30, i.e. the connecting linear direction of the first connecting member 11 and the second connecting member 21 is parallel to the extending direction of the guide member 30, so that the graduated scale can accurately reflect the length of the elastic material 200.

In some embodiments, the graduated scale may be made up of units of length such that the stretched or compressed length of the elastic material 200 may be calculated by calculation.

Optionally, the size interval of the graduated scale may be 1cm, the size interval of the graduated scale may also be 0.5cm, and the size interval of the graduated scale may also be 0.1 cm.

In other embodiments, the graduated scale includes a base length, which is the length of the elastic material 200 in a normal state, a plurality of scales are respectively disposed on both sides of the base length, and the scale marks the stretched or compressed length of the elastic material 200, so that a worker can know the stretched or compressed length of the elastic material 200 by looking at the scales.

In the description herein, particular features, structures, materials, or characteristics may be combined in any suitable manner in any one or more embodiments or examples.

The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
