Description

Technical Field

[0001] The utility model relates to the technical field of anti - tensile performance detection devices, in particular to an anti - tensile performance detection device for clothes. Background Art

[0002] The anti - tensile performance detection device is used to detect the anti - tensile strength of various articles, including at least two end clamps for clamping and fixing the sample to be detected. The existing common method is to use a screw - nut structure for clamping, which is rather troublesome to adjust. Content of the Utility Model

[0003] The technical problem to be solved by the utility model is: in order to overcome the above - mentioned problems, an anti - tensile performance detection device for clothes is provided, which solves the above - mentioned problems.

[0004] The utility model solves its technical problem by adopting the following technical solutions:

[0005] An anti - tensile performance detection device for clothes includes a detection frame. A threaded lead screw is rotatably arranged in the detection frame, and a lead - screw nut slide is also arranged to slide up and down in the detection frame. The lead - screw nut slide is in threaded connection with the threaded lead screw. A driving motor for driving the threaded lead screw is fixedly arranged at the upper end of the detection frame. After the driving motor is powered on, it drives the threaded lead screw to rotate, causing the lead - screw nut slide to move up and down. A tensiometer is fixedly arranged on the front end face of the lead - screw nut slide, and a clamp for clamping clothes is connected between the lower end of the detection frame and the tensiometer.

[0006] Preferably, the tensiometer and the clamp are connected by a connecting arm.

[0007] Preferably, the clamp is provided with an inner hole penetrating up and down, and a rotating shaft is rotatably arranged inside it. An elliptical pressing wheel is fixedly arranged on the rotating shaft.

[0008] Preferably, the clamp is provided with a clamping arc surface that fits the outer wall surface of the elliptical pressing wheel. When the elliptical pressing wheel rotates, the outer wall surface of the elliptical pressing wheel fits with the clamping arc surface.

[0009] Preferably, a stop arc surface is also arranged in the clamp to limit the continuous rotation of the elliptical pressing wheel. As shown in the figure, the long - side radius of the elliptical pressing wheel is greater than the distance from the axis of the rotating shaft to the stop arc surface.

[0010] Preferably, a number of rubber bumps are fixedly arranged at intervals on the outer side wall of the elliptical pressing wheel to increase the friction with the clothes, and a rotating handle fixed to the end of the rotating shaft is arranged outside the clamp.

[0011] The advantages and positive effects of the present utility model are as follows: Rotate the rotary handle to disengage the elliptical pressing wheel from the inner wall of the gripper, insert the cut clothing strip into the gap on both sides of the elliptical pressing wheel, and then rotate the elliptical pressing wheel so that its two ends clamp the clothing sample in the gripper. When the driving motor drives the lead screw nut slide to rise, the reaction force of the clothing sample will continue to tighten the elliptical pressing wheel, making the sample clamped tighter and tighter, effectively ensuring the clamping effect. And compared with the existing clamping method using a screw structure, it is more labor-saving and efficient. BRIEF DESCRIPTION OF THE DRAWINGS
