[0034] An electric heating plate is provided in the mold 212 for heating the mold 212 to simulate the temperature of the human body.

[0035] The stretching assembly includes an electric slide rail 202, an electric slider 203, a connecting frame 204 and an electric actuator 205; two electric slide rails 202 are fixed to the support frame 201; each electric slide rail 202 is slidably connected to two electric sliders 203; all electric sliders 203 are fixed to a connecting frame 204; an electric actuator 205 is fixed to the connecting frame 204, and the electric actuator 205 is an electric push rod; the telescopic part of the electric actuator 205 is fixed to the dynamometer 206; the connecting frame 204 is rotatably connected to the guide wheel 207; the connecting frame 204 is slidably connected to the rope I 208.

[0036] It also includes a nail plate 301, an elastic member I 302 and a tooth nail 303; the end of the rope I 208 away from the tension gauge 206 is slidably connected to the nail plate 301; the outer side of the end of the rope I 208 away from the tension gauge 206 is covered with an elastic member I 302, the elastic member I 302 is a spring, one end of the elastic member I 302 is fixed to the nail plate 301, and the other end of the elastic member I 302 is fixed to the fixed plate 209; a plurality of tooth nails 303 are fixed to the side of the nail plate 301 close to the fixed plate 209; the fixed plate 209 is provided with a through hole 2091 that cooperates with the tooth nail 303.

[0037] The fixing plate 209 and the nail plate 301 are both configured to be arc-shaped, so as to fit the protective gear 2 and increase the contact area with the protective gear 2 .

[0038] It also includes barbs 3031 ; each tooth nail 303 is fixed with a barb 3031 .

[0039] The protective gear 2 is put on the mold 212 in advance, as shown in FIG. Figure 1As shown, when the protective gear 2 is tested, the fixing plate 209 is manually held and the rope I 208 is pulled to move, and then the fixing plate 209 is inserted between the upper edge of the protective gear 2 and the upper part of the mold 212, and all the electric sliders 203 are controlled to move upward along the corresponding electric slide rails 202, and the movement of the electric slider 203 drives the connecting frame 204 to move, and the movement of the connecting frame 204 drives the electric actuator 205 to move, and the movement of the electric actuator 205 drives the dynamometer 206 to move until the value on the dynamometer 206 returns to zero, and then the electric actuator 205 is controlled to start and drive the dynamometer 206 to move downward, and the movement of the dynamometer 206 drives the rope I 208 to move, and the movement of the rope I 208 causes the guide wheel 207 to rotate, and at the same time, the movement of the rope I 208 drives the fixing plate 209 to move, and then the protective gear is pulled by the movement of the fixing plate 209. The upper edge of the protective gear 2 is pulled by the fixing plate 209, and the lower edge of the fixing plate 209 will press against the mold 212, thereby preventing the fixing plate 209 from being separated. After the value on the tension meter 206 reaches the preset value, the electric actuator 205 is controlled to start and drive the tension meter 206 to move upward and reset, so that the value on the tension meter 206 is reset to zero again. Then, the electric actuator 205 is controlled to start and drive the tension meter 206 to move downward in the same way as above, and then the upper edge of the protective gear 2 is pulled again. This cycle is repeated, thereby pulling the upper edge of the protective gear 2 through the fixing plate 209, causing the upper edge of the protective gear 2 to deform, thereby simulating the situation in which the protective gear 2 is deformed by the force during actual use, thereby evaluating the performance of the upper edge of the protective gear 2 after multiple stretching, thereby evaluating the restraint of the protective gear 2.

[0040] After the upper edge of the protective gear 2 is subjected to a tensile test, the fixing plate 209 is manually removed so that the fixing plate 209 is separated from the upper edge of the protective gear 2. Then, all the electric sliders 203 are controlled to move downward along the corresponding electric slide rails 202. The movement of the electric sliders 203 drives the connecting frame 204 to move, and the movement of the connecting frame 204 drives all the connected components to move, thereby moving the fixing plate 209 downward. The fixing plate 209 is then manually inserted between the lower edge of the protective gear 2 and the lower part of the mold 212. Then, in the same manner as above, the value on the tensile gauge 206 is reset to zero, and then the electric actuator 205 is controlled to start driving the tensile gauge 206 to move, thereby stretching the lower edge of the protective gear 2, causing the lower edge of the protective gear 2 to deform, thereby evaluating the performance of the lower edge of the protective gear 2 after multiple stretching.

[0041] It should be noted that by controlling the moving position of the connecting frame 204 and the guide wheel 207, the height of the rope I 208 can be controlled, thereby changing the direction of the tension of the rope I 208 and the fixed plate 209 on the protective gear 2, so that the upper edge of the protective gear 2 and the lower edge of the protective gear 2 are both stretched in different directions, and by controlling the electric actuator 205 to start and drive the dynamometer 206 to move, the preset value on the dynamometer 206 is changed, that is, the upper edge of the protective gear 2 and the lower edge of the protective gear 2 can be stretched with different strengths, thereby simulating the constraint performance of the upper edge of the protective gear 2 and the lower edge of the protective gear 2 after being stretched in different directions and with different strengths, thereby improving the accuracy of the test.

[0042] Next, the fixing plate 209 is inserted between the upper edge of the protective gear 2 and the upper part of the mold 212, and then the nail plate 301 is manually pressed to move the nail plate 301 along the rope I 208 and compress the elastic member I 302. The movement of the nail plate 301 drives all the tooth nails 303 to move, and the movement of the tooth nails 303 drives the corresponding barbs 3031 to move, so that the tooth nails 303 pierce the upper edge of the protective gear 2 and are inserted into the corresponding through holes 2091 on the fixing plate 209. The barbs 3031 are used to limit the position, so that the connection between the nail plate 301 and the fixing plate 209 is more stable, thereby 3 and the fixing plate 209 cooperate to clamp and limit the upper edge of the protective gear 2, and then control the motor I 211 to start, and the output shaft of the motor I 211 rotates to drive the mold 212 to rotate, so that the mold 212 and the protective gear 2 have relative friction, thereby simulating the phenomenon that the protective gear 2 rubs against human skin during use. After reaching the friction cycle, the motor I 211 is controlled to stop operating, and then combined with the above-mentioned tensile test, the upper edge and the lower edge of the protective gear 2 are tensile tested again, so as to evaluate the restraint performance of the protective gear 2 after friction and stretching, thereby further improving the accuracy of the test.

[0043] Example 2: Based on Example 1, Figure 6-Figure 9As shown, a simulation test system is also included; the support frame 201 is connected to the simulation test system; the simulation test system includes an elastic member II 401, a block 402, a motor II 403, a rotating shaft II 404, a rope II 405, a fixed block 406, a disc 407, a round rod 408 and a pull ring 4081; the upper part of the support frame 201 is fixed with an elastic member II 401, and the elastic member II 401 is a spring; the end of the elastic member II 401 away from the support frame 201 is fixed with a block 402; the fixed frame 210 is equipped with a motor II 403; the motor The output shaft of Ⅱ403 is fixedly connected to the rotating shaft Ⅱ404; the rotating shaft Ⅱ404 is rotatably connected to the fixed frame 210; a rope Ⅱ405 is wound around the rotating shaft Ⅱ404, and a hook is provided at the end of the rope Ⅱ405 away from the rotating shaft Ⅱ404; a fixed block 406 is fixedly connected to the inner side of the upper part of the mold 212; a disc 407 is rotatably connected to the fixed block 406; a round rod 408 is fixedly connected to the round rod 408; a pull ring 4081 is fixedly connected to the round rod 408; the pull ring 4081 is connected to the rope Ⅱ405; the pull ring 4081 is slidably connected to the clamping block 402.

[0044] A sliding groove 4082 is formed on the pull ring 4081 to increase the friction between the pull ring 4081 and the clamping block 402 .

[0045] It also includes a liquid outlet pipe 4071, a circular ring 409 and a joint 4091; a plurality of liquid outlet pipes 4071 are fixedly connected and connected to the circular disc 407 at equal intervals; the circular rod 408 is a hollow structure, and the circular rod 408 is connected to the circular disc 407; the circular ring 409 is fixedly connected and connected to the circular rod 408; and the joint 4091 is fixedly connected and connected to the circular ring 409.

[0046] An arc-shaped chamfer is provided on the upper portion of the mold 212 , and all the liquid outlet pipes 4071 are located above the arc-shaped chamfer on the mold 212 , so that the sweat simulating liquid flows to the outer wall of the mold 212 and is absorbed by the protective gear 2 .

[0047] The pump for delivering sweat simulating liquid is connected to the connector 4091 in advance, and then the card block 402 is manually grasped and driven to move, thereby stretching the elastic member II 401, and then the card block 402 is inserted into the pull ring 4081. Since the pull ring 4081 has a slide groove 4082, the friction between the pull ring 4081 and the card block 402 is increased, so that the card block 402 and the pull ring 4081 are tightly and firmly connected, and the card block 402 and the pull ring 4081 are prevented from being separated. Then, the movable end of the rope II 405 is manually pulled so that the hook on the movable end of the rope II 405 hooks the pull ring 4081. Figure 6As shown, the motor II 403 is then controlled to start, the output shaft of the motor II 403 rotates to drive the rotating shaft II 404 to rotate, the rotating shaft II 404 rotates the winding rope II 405, thereby moving the rope II 405, and the rope II 405 moves through the pull ring 4081 to drive the round rod 408 to move, thereby rotating the round rod 408, and the rotation of the round rod 408 drives all the connected parts to rotate and stretches the elastic member II 401, thereby causing the mold 212 to rotate with the rotating shaft I 2121 as the axis, and the rotation of the mold 212 drives the protective gear 2 to rotate, thereby causing the protective gear 2 to bend, thereby simulating the state of the protective gear 2 being bent during actual use. Then the motor II 403 is controlled to start, and the output shaft of the motor II 403 rotates to drive the protective gear 2 to rotate, thereby simulating the state of the protective gear 2 being bent during actual use. The rotating shaft II 404 rotates in the direction of the rotation, thereby releasing the rope II 405. At this time, the elastic force generated by the elastic member II 401 drives the clamping block 402 to move, and the movement of the clamping block 402 drives all connected components to move, thereby causing the mold 212 to rotate and reset. The rotation of the mold 212 drives the protective gear 2 to rotate, thereby causing the protective gear 2 to rotate and reset. Then, the motor II 403 is controlled to start in the same way as above, and the output shaft of the motor II 403 rotates to drive the rotating shaft II 404 to rotate, thereby causing the protective gear 2 to bend repeatedly, thereby simulating the state in which the human body moves after wearing the protective gear 2, causing the protective gear 2 to bend repeatedly. Then, a tensile test is performed on the protective gear 2 to evaluate the restraint performance of the protective gear 2 after repeated bending.

[0048] Moreover, since the human body is prone to sweating when exercising while wearing the protective gear 2, and sweat is easily soaked into the protective gear 2 and absorbed by the protective gear 2, over time, the restraint of the protective gear 2 is easily reduced, resulting in a reduction in the protection ability and comfort of the protective gear 2. In order to more comprehensively evaluate the restraint of the protective gear 2, the sweat simulating liquid is transported into the connector 4091 by controlling the pump machine for transporting the sweat simulating liquid of the external device, so that the sweat simulating liquid enters the ring 409 and flows along the ring 409, the round rod 408 and the disc 407, and finally flows out through all the liquid outlet pipes 4071. Moreover, since the upper part of the mold 212 is provided with an arc chamfer, all the liquid outlet pipes 4071 are located above the arc chamfer on the mold 212, so as to facilitate The sweat simulating liquid flows to the outer wall of the mold 212 and is absorbed by the protective gear 2, so that the sweat simulating liquid is absorbed in the protective gear 2. Then, the motor II 403 is controlled to start in the same manner as above, and the output shaft of the motor II 403 rotates to drive the rotating shaft II 404 to rotate, so that the protective gear 2 is repeatedly bent, thereby simulating the state in which sweat penetrates into the protective gear 2 and is absorbed by the protective gear 2 when the human body wears the protective gear 2 for exercise, and the state in which the protective gear 2 is repeatedly bent when the human body wears the protective gear 2 for exercise. Then, the protective gear 2 is subjected to a tensile test, so as to more comprehensively evaluate the restraint of the protective gear 2, so that the enterprise can further optimize the protective gear 2 to improve the protection capability and comfort of the protective gear 2.

[0049] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
