Description

Technical Field

[0002] During dog walking, to prevent pet dogs from biting others and to prevent them from getting lost, it is necessary to use a leash to keep the dog in check. As the dog walks, it often drags the leash around corners or on surfaces, which can wear it down over time. Therefore, during the production of dog leashes, it is necessary to conduct sampling tests on the abrasion resistance of the leashes to prevent them from being worn down during use. This requires the use of abrasion resistance testing equipment.

[0003] Publication (Announcement) No.: CN208765942U discloses a wear resistance testing device for dog leashes, including a mounting plate. Four columns are welded to the bottom outer wall of the mounting plate, located at the four corners near the plate. A pad is welded to the bottom end of each column. Two electric telescopic rods are welded to the middle of the top outer wall of the mounting plate, with a vertical plate welded to the top of each rod. A round-head plate is welded to the top outer wall of each of the two vertical plates. A round hole is formed in the middle of one side of each round-head plate, and a first bearing is welded to the inner wall of each hole. A common rotating rod is welded to the inner wall of each of the two first bearings. This invention provides a device for testing the abrasion resistance of dog leashes during production.
