Description

Technical Field

[0001] The invention relates to the technical field of sports equipment testing, and in particular to a sports equipment impact experiment continuous testing device. Background Art

[0002] The background technology of the continuous testing device for sports equipment impact experiment mainly comes from the high requirements for the quality and performance of sports equipment. With the popularization of sports and the diversification of sports events, the types and specifications of sports equipment are increasing, and their quality and performance are directly related to the safety of users and the use effect. Therefore, in the production process, the material properties of sports equipment must be strictly tested, among which the impact experiment test is an indispensable link. Traditional impact testing devices often have problems such as low testing efficiency and complicated operation, and cannot meet the needs of large-scale and high-efficiency testing. In order to solve these problems, the continuous testing device for sports equipment impact experiment came into being. It greatly improves the testing efficiency through a continuous and automatic testing process, ensuring the quality and performance of sports equipment.

[0003] After searching, the Chinese patent number CN115597814B discloses a sports equipment impact test continuous test device, including an impact unit and a delivery unit, the impact unit includes a motor, a housing and an impact assembly, the motor is arranged on the side of the housing, and the impact assembly is arranged on the other side of the housing. The delivery unit includes a transmission rack and a support plate, and the transmission rack is semi-engaged with the impact unit. When used, the present invention can make the impact test process and the transmission process coordinated, so that the test is continuous and the work efficiency is improved. Compared with the prior art, the Chinese patent number CN115597814B solves the problem that the existing sports equipment impact test device often tests one equipment before putting another equipment to be tested into the device for measurement, and cannot perform large-scale measurements, resulting in a waste of time and resources.

[0004] However, in actual use of the above device, sports equipment such as clappers lack limiters when undergoing impact tests in the impact groove. The impacted sports equipment is easily bounced upward by the impact, causing the equipment to detach from the impact groove, affecting the continuity of the impact test. Therefore, a continuous testing device for impact tests on sports equipment is proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the problem in the prior art that sports equipment such as clappers lack limit stops when undergoing impact tests in impact grooves, and the impacted sports equipment is easily bounced upwards by the impact, thereby causing the equipment to detach from the impact groove, affecting the continuity of the impact test. A continuous testing device for impact tests on sports equipment is proposed to solve the problem.

[0008] The worm is meshingly connected with a worm wheel, and the worm wheel is rotationally connected to a limit housing. A seventh gear is fixedly connected to the side of the worm wheel away from the limit housing. The seventh gear is meshingly connected with a first rack, and the first rack is slidingly connected to the limit housing. The first rack is fixedly connected to the impact groove. After the sports equipment is placed in the impact groove, the third motor is started, and the worm and the sixth gear are driven to rotate by the third motor. The rotation of the worm drives the seventh gear to move along the meshing first rack, thereby driving the limit housing to move to limit the equipment. While the limit housing moves, the sixth gear rotates synchronously, and the pressure plate is driven downward by the rotation of the sixth gear, thereby pressing the sports equipment downward. A sliding groove for the first rack and the second rack to slide is provided inside the limit housing.

[0009] The above technical solution further includes:

[0010] An adjusting mechanism is arranged inside the impact groove, and the adjusting mechanism drives the adjusting plates arranged on both sides to move inwards to adjust the space area inside the impact groove.

[0011] The adjustment mechanism comprises an adjustment housing fixedly connected to the inside of the impact groove, a fourth motor is arranged on one side of the adjustment housing, and an adjustment component is arranged on the output end of the fourth motor.

[0018] The present invention has the following beneficial effects:

[0019] 1. In the present invention, when sports equipment such as rackets and ball boards are placed in the impact groove, the adjustment mechanism is started, and the adjustment plates arranged on both sides can be driven to move inward through the adjustment mechanism, so that the area in the impact groove can be flexibly adjusted according to the size of the equipment. After the equipment is placed in the impact groove, the third motor is started to drive the worm and the sixth gear to rotate synchronously.
