Description

Technical Field

[0001] The invention relates to the technical field of high jump protection pad testing, in particular to a device for testing the protective effect of a high jump protection pad. Background Art

[0002] High jump is one of the field events in track and field sports. It is a sport in which the human body jumps over high obstacles through a series of actions including running-up, taking-off, flying and landing. The main facility among these items is the high jump stand, which is composed of columns, crossbar racks and crossbars. Various types of high jump stands or columns with sturdy structures can be used in competitions, and there must be crossbar racks that can stably place the crossbars. With the general improvement of people's living standards, sports and fitness are becoming more and more indispensable activities in our daily lives, both for operators and athletes, and safety during fitness is of paramount importance. As a kind of safety protection, cushioning pads are widely used. High jump protective pads are the only protective gear to protect the health of athletes in high jump sports, so the protective pads used in high jump need to undergo more rigorous protection effect testing operations, otherwise the safety of use cannot be guaranteed.

[0003] For example, the patent document with the announcement number CN 217033439 U discloses a buffer pad testing device, which belongs to the field of detection technology. The testing device includes an elastic impact testing mechanism, a clamping and fixing mechanism, a heating mechanism, and a lifting mechanism, and the elastic impact testing mechanism, the clamping and fixing mechanism, the heating mechanism, and the lifting mechanism are combined to form the testing device. Compared with the prior art, the beneficial effects of the present invention are: first, the present invention can set different impact forces through the elastic impact testing mechanism, can continuously perform impacts of different forces, and has a fast impact speed, which effectively improves the test efficiency; secondly, the present invention can set the test temperature of the buffer pad through the heating component, and monitor the temperature changes of the buffer pad during the test process, thereby improving the accuracy of the test; finally, the present invention has a simple structure, low cost, and is easy to use and promote.

[0004] However, when the structure is used to test the protective effect of the high jump protective pad, due to the limitation of its own structure, it can usually only perform a simple mechanized pressure test on the surface of the high jump protective pad. It cannot adaptively complete the rebound force test when the entire protective pad is pressed down as a whole, and cannot immediately discover the internal voids that may exist in the high jump protective pad, which affects the overall safety protection effect during high jump. At the same time, the first contact point when a high jumper lands is often a concentrated point in the center. The test equipment cannot simulate the concentrated explosive force of the high jumper when actually landing at this position. Moreover, the force applied to the landing of the high jumper is not a vertical force, and the force in the inclined direction may cause the protective pad to move, causing landing injuries. It is impossible to perform a more comprehensive test of the protective effect of the high jump protective pad, and it is impossible to meet daily use needs. Therefore, it is urgent to design a protective effect test device for a high jump protective pad to solve the above problems. Summary of the invention

[0005] The purpose of the present invention is to provide a protective effect testing device for a high jump protective pad, so as to solve the problem that the existing structure proposed in the above background technology can only perform a simple mechanized pressure test operation on the surface of the high jump protective pad due to the limitation of its own structure when performing the protective effect testing operation of the high jump protective pad, and it is unable to adaptively complete the rebound force test of the entire protective pad when the entire protective pad is pressed downward as a whole, and is unable to immediately discover the internal voids that may exist in the high jump protective pad, which affects the overall safety protection effect during the high jump. At the same time, the first contact position when a high jump long-distance athlete lands is often a concentrated point in the center. The test equipment cannot simulate the concentrated explosive force of the high jump athlete when actually landing at this position, and the force applied to the long-distance athlete when landing is not a vertical force. The force in the inclined direction may cause the protective pad to move, causing landing injuries. Therefore, a more comprehensive protective effect testing operation of the high jump protective pad cannot be performed, and the daily use needs cannot be met.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The protective effect testing device for the high jump protective pad can enable the device to replace the high jump protective pad to fit the actual high jump movement by arranging a storage rack, a limiting angle column, a drive shaft seat, a horizontal transmission frame, a vertical transmission frame, a drive motor, an equipment inner frame, a shrinking rubber cover, a lifting slide seat, a test pressure seat, a piston cylinder, a test connection seat, a side plate, a force storage spring, a second air control pump, a force storage air bag, a conical top seat, a top connection seat, a detection frame, a corner pressure sensor, a center cone seat, a center pressure sensor, a first limiting plate, a second limiting plate, a third air control pump, an angle air bag, a vertical transmission belt, a horizontal transmission belt, a lifting screw rod, a bearing seat, a limiting slide groove, a limiting slide rod, a lifting slider and a lifting wire sleeve. In the actual use process, the staff first puts the protective pad that needs to be tested for protective effect into the bottom of the storage rack, and then starts the driving motor at one end of the surface of the vertical transmission rack, and drives the horizontal transmission belts at both ends of the bottom to rotate synchronously through the vertical transmission belt at one end, so that the lifting screws at both ends of the bottom of the two sets of horizontal transmission belts are rotated and adjusted at their respective bearing seats, so that the lifting slide at the bottom of the storage rack can drive the test pressure seat at the bottom through the limit slide bars, lifting sliders and lifting wire sleeves at the four corners of the side to perform synchronous and uniform up and down lifting and adjustment operations, in conjunction with the limit corner columns and drive shaft seats at the four corners of both sides of the storage rack and At the limiting slide grooves at the four corners of the inner walls of the side panels on both sides of the storage rack, stable limits are placed on the overall up and down lifting and lowering adjustment of the lifting slide and the test pressure seat. Under the stable pulling and positioning of the retracted rubber cover on the surface of the lifting slide, the overall downward pressure detection of the high jump protective pad is carried out through the detection frame inside the test pressure seat. The corner pressure sensors at the four corners of the inner wall of the detection frame are used to detect the elastic force of each position of the high jump protective pad to avoid the hollow problem inside the high jump protective pad. After the overall detection is completed, the second air control pump at the bottom of the test seat and the force storage spring can be started to press upward to contract and store force in the force storage spring. Then, when the force storage airbag is instantly deflated and loses its upward force, the force storage spring can directly drive the force storage airbag to move. The conical top seat and top connecting seat at the bottom of the bag are pressed down at the central cone seat and central pressure sensor in the center of the detection frame, thereby simulating the instantaneous explosive force of the athlete when falling from a high jump, and performing detection operations on the center of the high jump protective pad. At the same time, the third air control pump machine on the side of the test connecting seat can be adapted and started on a daily basis to drive the angle air bags on the four sides of the test connecting seat to perform adaptive contraction and adjustment. The test connecting seat in the center of the piston cylinder is limited by the first limit plate and the second limit plate at the upper and lower ends to adjust the force angle, thereby simulating landing forces in different directions, and completing the safety protection test of whether the high jump protective pad will be displaced, which reflects the practicality of the equipment design.

[0017] The protective effect testing device for the high jump protective pad further improves the overall use effect of the equipment by arranging a material receiving seat, an adjusting base, a lifting airbag, a lifting unit, a first air control pump, a load plate, a first conveying frame, a second conveying frame, a conveying roller, a conveying inclined plate, a conveying pad, a test trough, a test top plate, a positioning airbag and a displacement sensor. In daily use, the staff can start the conveying rollers on the surfaces of the first conveying frame and the second conveying frame at the front and rear ends of the material receiving seat, and then cooperate with the conveying pads on the surfaces of the conveying inclined plates at the front and rear ends of the first conveying frame and the second conveying frame to quickly convey and position the high jump protective pad on the surface of the material receiving seat one by one, so as to more appropriately complete the protective effect testing operation of the high jump protective pad, and when the high jump protective pad falls on the surface of the material receiving seat, it can be adaptively started at this time. The first control air pump inside the lifting unit is driven to adaptively adjust the lifting airbag inside the adjustment base, thereby driving the top load-bearing plate to perform the lifting and positioning operation of the high jump protective pad inside the material receiving seat, and then a more stable positioning test operation is performed inside the test slot of the material receiving seat. At the same time, the positioning airbag inside the test top plate can be adaptively started on a daily basis, and the four groups of test top plates can be adaptively connected to the sides of the high jump protective pad to position and fix the high jump protective pad. When the test socket inside the piston cylinder is subjected to multi-angle force testing, when the high jump protective pad is shifted as a whole, it can be detected at the displacement sensors at the four corners of the tested top plate, and the center of the high jump protective pad can be reset through the test top plate and the positioning airbag, and multiple detection operations can be repeated quickly, reflecting the comprehensiveness of the equipment design.
