Description

Belt endurance test structure of bending Technical Field The utility model relates to the technical field of belt testing, in particular to a belt bending endurance test structure. Background In the field of existing belt testing equipment, a common testing method mainly focuses on service life assessment of an industrial transmission belt, namely, durability is judged by simulating the service time of the belt in mechanical operation. However, for a leather belt worn by a human body (hereinafter referred to as "clothing belt"), there are significant differences in usage scenario and stress characteristics from an industrial belt. In the daily wearing process, the clothing belt mainly bears the friction effect between the clothing belt and parts such as clothing, fasteners and the like caused by human body activities. Because of the variety of human body movements, such as bending, sitting or walking, the clothing belt needs to maintain durability in different angles of bending, and at the same time, the surface wear resistance is also a key performance index due to repeated contact with fasteners or clothing. The existing test equipment is designed for continuous operation of industrial belts, and less attention is paid to performance change of the clothing belt caused by bending and friction in the wearing process. For example, apparel belts often lack specialized testing means for their durability in a conventional or taut state, their fatigue resistance at different bending angles, and their wear resistance when rubbed against clothing such as fasteners. The evaluation of the durability of the clothing belt is not comprehensive enough, and the performance of the clothing belt in an actual wearing scene cannot be accurately reflected. Disclosure of utility model Aiming at the technical problems in the prior art, the utility model provides the belt bending durability test structure for solving the problems that the evaluation of the durability of the clothing belt is not comprehensive enough and the performance of the clothing belt in an actual wearing scene cannot be accurately reflected. The technical scheme for solving the technical problems is as follows, the belt bending endurance test structure comprises: The support frame comprises a connecting arm, and two first supports and second supports which are parallel to each other and are L-shaped, and the connecting arm is fixed between the lower parts of the first supports and the second supports; The rotary driving piece is arranged above the first support; A first pulley disposed on a driving end of the rotary driving member; The second belt pulley is rotationally connected to one side of the connecting arm, which is close to the first support, through a rotating shaft; the linear module is arranged between the first support and the upper part of the second support; the third belt pulley is rotationally connected to the moving end of the linear module through a rotating shaft; The fourth belt pulley is rotationally connected to one side of the connecting arm, which is close to the second support, through a rotating shaft; The test belt is sleeved outside the first belt pulley, the second belt pulley, the third belt pulley and the fourth belt pulley The friction test assembly comprises a first friction wheel and a second friction wheel which are respectively positioned on one side of the test belt, wherein the first friction wheel is detachably connected to the first support, and the second friction wheel is detachably connected to the second support.
