DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0035] like Figure 1-Figure 5 As shown, a zipper fatigue strength detection device proposed in one embodiment of the present application includes:

[0036] A water storage seat frame 1 is fixedly connected to a support vertical plate 2, a vertical through groove 201 is constructed in the middle of the support vertical plate 2, and the top surface of the water storage seat frame 1 is much larger than the cross-sectional size of the support vertical plate 2, so that water can be better received and stored;

[0037] The bottom corner clamping member 3 comprises a T-shaped block 301 which is detachably connected to one side of the supporting vertical plate 2 and is located directly below the vertical through groove 201. The supporting vertical plate 2 is provided with a plurality of slots in an array along its height direction. An inserting block inserted in the slot is provided on one side of the T-shaped block 301, and a fixing bolt threadedly connected in the slot is installed through the T-shaped block 301. By changing the inserting block and inserting it into different slots, the height of the T-shaped block 301 can be adjusted. The T-shaped block 301 is hinged with S-shaped flip plates 302 at both ends horizontally. The upper ends of the two S-shaped flip plates 302 are opened and arranged opposite to each other and the ends are connected with clamping plates 303. The clamping plates 303 are used to clamp the two bottom corners of the zipper. The lower end of the S-shaped flip plate 302 is connected with a weight seat 304. The weight seat 304 is used to install weights, which are mainly used to increase gravity to pull the upper end of the S-shaped flip plate 302 to always flip in the opposite direction.

[0038] The side clamping members 4 are arranged in the middle of the supporting vertical plate 2 and on both sides of the vertical through groove 201, and are used to clamp the two sides of the zipper to assist the zipper to unfold;

[0039] The reciprocating pull member 5 comprises a moving block 501 slidably mounted in the vertical through groove 201. A driving member 502 for driving the moving block 501 to reciprocate is provided on the water storage seat frame 1. The moving block 501 is mainly used to connect the slider of the zipper.

[0040] When the device performs fatigue strength testing on the zipper under normal conditions, the forked end of the zipper can be first clamped on the two clamping plates 303 of the bottom corner clamping member 3, and then the closed end can be placed on the upper side of the supporting vertical plate 2, and then the side clamping members 4 are used to clamp the two sides of the middle part of the zipper to unfold the zipper, and the driving member 502 is used to drive the moving block 501 to move up and down in the vertical through groove 201 to achieve the closing and opening operations of the zipper, wherein when the moving block 501 moves up, the zipper is opened, and the gravity of the weight seat 304 can automatically drive the S-shaped flip plate 302 to flip to both sides, so as to open and assist in opening the zipper, and when the moving block 501 moves down, it also needs to withstand the gravity of the weight seat 304 to close the zipper, and by replacing the weight of the weight on the weight seat 304, the bearing capacity of the zipper can be better tested;

[0041] The intermittent water spraying mechanism 6 comprises a pressurized water pumping frame 601 installed through the supporting vertical plate 2, a water pumping pipe 602 connected to the water storage seat frame 1 is fixedly connected to the top side of the pressurized water pumping frame 601, a water outlet pipe 603 is connected to one end of the pressurized water pumping frame 601, a linkage member 604 for intermittently increasing the pressure of the pressurized water pumping frame 601 is installed between the pressurized water pumping frame 601 and the driving member 502, and the other end of the water outlet pipe 603 is fixedly connected to a water spraying pipe 605 arranged on the outside of the vertical through groove 201. When it is necessary to perform fatigue strength test on the zipper after immersion in water, water can be directly poured into the water storage seat frame 1, and the pressurized water pumping frame can be driven by the transmission of the driving member 502 and the linkage member 604. 601 performs intermittent pressurization and water pumping operations, uses the water pumping pipe 602 to pump water into the pressurized water pumping frame 601, and then continues to pressurize the interior thereof, so as to spray the water source on the zipper being tested through the water outlet pipe 603 and the water spraying pipe 605. It should be noted that since the linkage 604 is in intermittent motion, the water spraying operation is also intermittent, which can simulate the situation in which the zipper is used again after being flushed by water after being used a certain number of times in daily life, thereby increasing the detection range of the device and eliminating the need for manual water spraying on the zipper on a regular basis, thereby increasing convenience, and the water storage seat frame 1 can receive the dripping water source, which can be extracted and reused through the water pumping pipe 602, thereby saving resources.

[0042] like Figure 2 As shown, in some embodiments, the water storage seat frame 1 includes a bottom frame 101, a mesh plate 102 is constructed on the upper end of the bottom frame 101, a sponge block 103 is fixedly filled in the middle of the bottom frame 101, one end of the water suction pipe 602 passes through the mesh plate 102 and the sponge block 103 and a filter head 6021 is fixedly connected to the end. The mesh plate 102 is mainly used to receive dripping water while also shielding large external debris to avoid polluting the water source, and the sponge block 103 is used to filter the water source to ensure the subsequent recycling of the water source and increase safety.

[0043] like Figure 1-Figure 2As shown, in some embodiments, four vertical grooves 202 are constructed on one side of the supporting vertical plate 2, and the four vertical grooves 202 are distributed in pairs on both sides of the vertical through groove 201. The side clamping member 4 includes a slider 401 slidably installed in the vertical groove 202, and a guide member 402 is rotatably installed on the slider 401 arranged close to the vertical through groove 201. One end of the guide member 402 is connected to a clamping block 403 and the other end is connected to a pull rope 404. A pulley 405 is rotatably installed on the slider 401 away from the vertical through groove 201, and the pull rope 404 is wound around the pulley 405 and the bottom end is connected to a weight plate 406, wherein the clamping block 403 is used to clamp the edge of the zipper, and the pulley 405 is used to bend the pull rope 404 to transfer the gravity of the weight plate 406 downward. It is a horizontal pulling force. When the device is in use, the guide member 402 is mainly used to guide the reciprocating movement of the clamping block 403, so that it always maintains a linear motion tangent to the pulley 405, so as to better assist in opening the two sides of the zipper. The position of the slider 401 can be adjusted by setting the vertical groove 202, so as to change the relative position of the guide member 402 and the pulley 405. The specific operation is to move the slider 401 of the guide member 402 to below the slider 401 of the pulley 405. The greater the distance between the two, the greater the amplitude of the zipper opening, and thus the longer the distance the slider can move upward, and the pulling force required to pull the slider downward can also be increased, thereby increasing the load of the zipper and improving the test range of the device.

[0044] like Figure 2 As shown, in some embodiments, a positioning member 7 is further included, and the positioning member 7 includes a plurality of positioning blocks 701 slidably installed in the vertical slot 202, and a fastening bolt 702 is installed through a thread on the positioning block 701 and abuts against the vertical slot 202. Two positioning blocks 701 are arranged in the vertical slot 202 where the guide member 402 is installed, and are respectively located on the upper and lower sides of the slider 401. A positioning block 701 is arranged in the vertical slot 202 where the pulley 405 is installed and abuts against the lower side of the slider 401. The positioning block 701 The position is fixed by fastening bolts 702. The positioning block 701 at the bottom of the slider 401 is mainly used to perform bottom positioning of the guide member 402 and the pulley 405. The pulley 405 is always subjected to the downward pulling force of the pull rope 404. Therefore, a single positioning block 701 can be used to support and limit its position. The guide member 402 can adjust the movable distance of the guide member 402 as the position of its top positioning block 701 changes, thereby assisting in adjusting the opening angle of the zipper and increasing the flexibility of the device.

[0045] like Figure 5-Figure 6As shown, in some embodiments, the guide member 402 includes a rotating block 4021 rotatably mounted on the slider 401, a threaded rod 4022 is threadedly installed on the rotating block 4021, a positioning nut 4023 is threadedly sleeved on one end of the threaded rod 4022 and a slide block 4024 is fixedly connected to the other end, an L-shaped sleeve 4025 is slidably sleeved on the slide block 4024, and the clamping block 403 is connected to the end of the L-shaped sleeve 4025 opposite to the rotating block 4021, and the L-shaped sleeve 4025 is connected to the end of the L-shaped sleeve 4025 opposite to the rotating block 4021. The other end of the sleeve 4025 is connected to the drawstring 404. When the zipper slider moves up and down, it will drive the clamping block 403 and the L-shaped sleeve 4025 to move on the slide block 4024, thereby pulling one end of the drawstring 404 to move. The L-shaped sleeve 4025 slides with the slide block 4024, so that one end of the drawstring 404 can move in a straight line, maintain the stability of the two sides of the zipper, avoid shaking, and increase the safety of the test.

[0046] like Figure 4 and Figure 6 As shown, in some embodiments, the clamp 303 and the clamp block 403 have the same structure and both include a button 8 that threads through the S-shaped flip plate 302 or the L-shaped sleeve 4025, and a clip 801 is fixedly connected to the end of the button 8. The side of the clip 801 facing the S-shaped flip plate 302 or the L-shaped sleeve 4025 is configured with multiple protrusions 802. When the zipper needs to be clamped, the distance between the clip 801 and the S-shaped flip plate 302 or the L-shaped sleeve 4025 can be adjusted by utilizing the thread cooperation of the button 8 and the S-shaped flip plate 302 or the L-shaped sleeve 4025, so that the zipper can be clamped, which makes the operation more convenient, and the protrusions 802 are provided to increase friction and improve the stability of the clamping.

[0047] like Figure 3 As shown, in some embodiments, the driving member 502 includes a mounting frame 5021 fixedly connected to the water storage seat frame 1, a turntable 5022 is rotatably mounted on the mounting frame 5021, a driving motor 5023 for driving the turntable 5022 to rotate is fixedly connected to the mounting frame 5021, a connecting rod 5025 is eccentrically hinged to the turntable 5022 through a hinge column 5024, the other end of the connecting rod 5025 is hinged to the moving block 501, and the hinged cooperation between the turntable 5022, the connecting rod 5025 and the moving block 501 can form a crank sliding block reciprocating structure, and the continuous unidirectional rotation of the motor is used to drive the moving block 501 to move back and forth, so as to realize the reciprocating opening and closing operation of the zipper.

[0048] like Figure 7-Figure 8As shown, in some embodiments, the pressurized water pumping frame 601 includes a rectangular frame 6011 fixedly installed on the support vertical plate 2, the water pumping pipe 602 is connected to the top side of one end of the rectangular frame 6011 through a one-way valve 6012, the water outlet pipe 603 is connected to the bottom side of the rectangular frame 6011 and is located below the water pumping pipe 602, and a trigger 6013 for controlling the opening and closing of the water outlet pipe 603 is installed on the bottom side of the rectangular frame 6011. When the pressurized water pumping frame 601 is pumping pressure, the trigger 6013 is in a closed state. , the water outlet pipe 603 is not connected, while the water pumping pipe 602 and the one-way valve 6012 can be connected toward the rectangular frame 6011 to extract the water source in the water storage seat frame 1. When the pressurized water pumping frame 601 is pressurized, the one-way valve 6012 closes the water pumping pipe 602. When the pressure is increased to a certain level, the trigger 6013 opens to discharge the pressure together with the water source in the rectangular frame 6011 through the water outlet pipe 603, so that the water spray pipe 605 sprays the zipper, thereby realizing an intermittent spray test.

[0049] like Figure 8 As shown, in some embodiments, the linkage 604 includes a reciprocating screw rod 6041 that rotates and passes through the rectangular frame 6011, and the reciprocating screw rod 6041 is meshed and sleeved with an extrusion block 6042 that is slidably installed in the rectangular frame 6011. A groove wheel 6043 is rotatably installed on the mounting frame 5021, and one of the slots on the groove wheel 6043 is sleeved on the hinge column 5024. One end of the reciprocating screw rod 6041 is fixedly connected to the center of the groove wheel 6043. When the driving motor 5023 is in operation, the turntable 5022 is driven to rotate continuously, so that the hinge column 5024 is intermittently engaged with the groove wheel 6043, thereby driving the reciprocating screw rod 6041 to rotate. Because the turntable 5022 rotates one circle to drive the groove wheel 6043 to rotate one tooth groove angle, the rotation speed of the reciprocating screw rod 6041 can be greatly reduced, thereby simulating the length of the zipper. In the case of contact with water after use, the reciprocating screw 6041 can drive the extrusion block 6042 to move toward the direction of the water outlet pipe 603 and the water suction pipe 602. At this time, it is a pressurized operation. When the extrusion block 6042 passes over the trigger member 6013, the trigger member 6013 can be used to open the opening of the water outlet pipe 603 to release the water source and achieve the spraying effect. The extrusion block 6042 needs to move a certain distance to pass the trigger member 6013 first, so that the pressure in the cavity can be increased. After the pressure is released, the extrusion block 6042 moves in the opposite direction and uses the trigger member 6013 to close the opening of the water outlet pipe 603. At this time, the cavity will continue to form a negative pressure, so as to use the one-way valve 6012 to connect the water suction pipe 602 to automatically extract the water source in the water storage seat frame 1. The cycle can achieve intermittent water spraying effect. The automatic operation does not require human operation, which increases the convenience of the device.

[0050] like Figure 8As shown, in some embodiments, the trigger member 6013 includes a U-shaped plate 60131 that slides through the bottom of the rectangular frame 6011, and the top of the U-shaped plate 60131 is close to the end of the extrusion block 6042. The inclined surface of the bevel 60132 is set toward the extrusion block 6042, and the other end of the top of the U-shaped plate 60131 is tightly fitted at the connection between the rectangular frame 6011 and the water outlet pipe 603. The bottom of the rectangular frame 6011 is configured with a support frame 60133, and the support frame 60133 is connected with a support spring 60134 for supporting the U-shaped plate 60131. When the extrusion block When 6042 moves toward the water outlet pipe 603, it will gradually come into contact with the bevel 60132 of the U-shaped plate 60131, thereby squeezing the U-shaped plate 60131 to move downward, thereby driving the other end of the U-shaped plate 60131 to move downward synchronously, thereby opening the connection between the water outlet pipe 603 and the rectangular frame 6011, and releasing the pressure. When the squeezing block 6042 is reset, it will detach from the U-shaped plate 60131, thereby pushing the other end of the U-shaped plate 60131 through the support spring 60134 to re-close the water outlet pipe 603, automatically triggering opening and closing, without the need for electricity, and saving resources.
