Description

Technical Field

[0001] This utility model relates to the field of shoe sole performance testing technology, specifically a shoe sole puncture test structure. Background Technology

[0002] Safety shoes, as an important type of personal protective equipment, are widely used in complex working environments such as construction, manufacturing, and logistics. Their main function is to protect the feet from injuries such as punctures and crushing from sharp objects, ensuring the safety of workers. Among these, puncture resistance is one of the core indicators for evaluating the quality of safety shoes, directly related to the foot safety of workers in complex environments.

[0003] However, after producing safety shoes, shoe factories typically need to conduct puncture resistance tests on batches of shoes to ensure they meet relevant safety standards. Because the tests involve various types and sizes of shoes, the shoes to be tested need to be frequently changed during the process. Existing testing methods usually involve manual operation: first, removing the shoes from the testing device, then placing new shoes and securing them in place. This process is not only cumbersome but also time-consuming and labor-intensive, resulting in low testing efficiency. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a shoe sole puncture test structure. This solves the problem that existing testing methods usually involve manual operation, where the shoe is first removed from the testing device, and then a new shoe is placed and fixed in place. This process is not only cumbersome but also time-consuming and labor-intensive, resulting in low testing efficiency.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: a shoe sole puncture test structure, comprising:

[0006] Base;

[0007] A column, one end of which is vertically fixed to the base, and the other end of which is arranged away from the base;

[0008] Support arms, which are fixed to the top two sides of the column;

[0009] A connecting rod, which is fixed between the bearing arms;

[0010] A movable pulley, which is sleeved on the outside of the connecting rod;

[0011] A U-shaped suspension plate is fixed to the bottom of two support arms, wherein the bottom of the suspension plate has a through hole;

[0012] A sliding rod, one end of which passes through a through hole in the suspension plate;

[0013] A sharp object, which is fixed to one end of the slide bar through the through hole;

[0014] A traction rope, one end of which is fixed to the top of the slide bar, and the other end of which is wrapped around the outside of the movable pulley;

[0015] A storage platform for placing shoes includes a drive unit, a turntable, and multiple shoe holders for lifting the shoes. The drive unit is mounted on a base, the turntable is fixed to the drive end of the drive unit, and the multiple shoe holders are arranged in a circular array on top of the turntable, with one shoe holder located on the axis of a sliding rod.

[0016] The beneficial effects of this utility model are:

[0017] 1) By using a traction rope and a movable pulley, the sliding rod can be pulled to raise a sharp object to a predetermined height. After the traction rope is released, the sharp object falls freely and impacts the sole of the shoe, completing the puncture resistance test. Since multiple shoe holders are arranged in a circular array on the top of the turntable, and one of the shoe holders is located on the axis of the sliding rod, the turntable can be rotated by a drive component, allowing each shoe holder to move sequentially to the axis of the sliding rod. This enables rapid switching of the shoes to be tested without the need for manual disassembly and re-fixing of the shoes, making the operation simple and efficient, thereby improving testing efficiency.

[0018] Based on the above technical solution, the present invention can be further improved as follows.

[0019] Furthermore, a counterweight assembly is provided at the other end of the slide bar.

[0020] Furthermore, the counterweight assembly includes a buffer sleeve, a locking block, an embedding groove, and a plurality of annular counterweight blocks. The buffer sleeve is fixed to the outside of the other end of the slide rod, the locking block is fixed to the outside of the buffer sleeve, and the embedding groove is opened on the outside of each counterweight block. Each counterweight block is fitted onto the outside of the buffer sleeve through the embedding groove.

[0021] Furthermore, the opening width of the embedding groove is greater than the diameter of the buffer sleeve, and the diameter of the buffer sleeve is greater than the diameter of the through hole.

[0022] The beneficial effect of adopting the above-mentioned further solution is that by fixing a buffer sleeve to the outside of the other end of the slide bar and setting its diameter to be larger than the through hole, it effectively prevents the slide bar from completely falling out of the through hole of the suspension plate during free fall, ensuring the stability and safety of the testing device. At the same time, a locking block and multiple ring-shaped counterweights are set on the outside of the buffer sleeve, and the counterweights are detachably fitted on the outside of the buffer sleeve using an embedded groove. The number of counterweights can be flexibly adjusted according to the testing requirements, thereby increasing the piercing force of sharp objects on the sole of the shoe and improving the flexibility of the test.

[0023] Furthermore, a guide assembly is also provided on the outside of the slide bar.

[0024] Furthermore, the guide assembly includes a guide sleeve, a first support rod, and a second support rod. The guide sleeve is sleeved on the outside of the slide rod. One end of the first support rod and the second support rod are respectively fixed to the outside of the guide sleeve, and the other end of the first support rod and the second support rod are respectively fixed to both sides of the suspension plate.

[0025] The beneficial effect of adopting the above-mentioned further solution is that by setting a guide sleeve on the outside of the slide bar, the path of the slide bar falling freely is guided and positioned for a second time, which effectively ensures the stability of the slide bar's falling trajectory, thereby improving the positional accuracy of sharp objects piercing the sole of the shoe.

[0026] Furthermore, the driving component includes a drive motor.

[0027] Furthermore, each of the shoe racks includes a support rod and a support plate, one end of the support rod is fixed to the top of the turntable, the bottom of one side of the support plate near the end is fixed to the other end of the support rod, and one of the support rods is coaxial with a slide bar.

[0028] Furthermore, a locking rod is fixedly connected to one end of the slide rod that penetrates the through hole.

[0029] The beneficial effect of adopting the above-mentioned further solution is that by fixing a locking rod to one end of the slide rod that penetrates the through hole, it is possible to effectively prevent the sharp object from coming out of the through hole of the suspension plate when the slide rod is pulled up to the predetermined height.

[0036] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0037] Safety shoes, as an important type of personal protective equipment, are widely used in complex working environments such as construction, manufacturing, and logistics. Their main function is to protect the feet from injuries such as punctures and crushing from sharp objects, ensuring the safety of workers. Among these, puncture resistance is one of the core indicators for evaluating the quality of safety shoes, directly related to the foot safety of workers in complex environments.

[0038] However, after producing safety shoes, shoe factories typically need to conduct puncture resistance tests on batches of shoes to ensure they meet relevant safety standards. Since the tests involve various types and sizes of shoes, the shoes to be tested need to be frequently changed during the testing process. Existing testing methods usually involve manual operation, first removing the shoes from the testing device, then placing new shoes and securing them in place. This process is not only cumbersome but also time-consuming and labor-intensive, resulting in low testing efficiency. To address this issue, the inventor has proposed a sole puncture test structure to solve the above problems.

[0039] The present invention provides the following preferred embodiments.

[0040] like Figures 1-4 As shown, a shoe sole puncture test structure includes:

[0041] Base 1;

[0042] Column 2, one end of column 2 is vertically fixed to base 1, and the other end of column 2 is arranged away from base 1;

[0043] Support arm 3, which is fixed to the top two sides of column 2;

[0044] Connecting rod 4 is fixed between bearing arms 3;

[0045] Movable pulley 5 is sleeved on the outside of connecting rod 4;

[0046] A U-shaped suspension plate 6 is fixed to the bottom of two support arms 3, and a through hole is provided at the bottom of the suspension plate 6.

[0047] The slide rod 7 has one end that passes through the through hole of the suspension plate 6;

[0048] Sharp object 8 is fixed to one end of the slide bar 7 through the through hole, wherein the sharp object 8 is conical;

[0049] The traction rope 9 has one end fixed to the top of the slide bar 7 and the other end wrapped around the outside of the movable pulley 5.

[0050] The storage platform 10 for placing shoes includes a drive unit 101, a turntable 102, and multiple shoe holders for lifting shoes. The drive unit 101 is mounted on the base 1, the turntable 102 is fixed to the drive end of the drive unit 101, and the multiple shoe holders are arranged in a circular array on the top of the turntable 102, with one of the shoe holders located on the axis of the slide bar 7.

[0051] By using the traction rope 9 and the movable pulley 5 in combination, the sliding rod 7 can be pulled to raise the sharp object 8 to a predetermined height. After the traction rope 9 is released, the sharp object 8 falls freely and impacts the sole of the shoe, completing the puncture resistance test. Since multiple shoe holders are arranged in a circular array on the top of the turntable 102, and one of the shoe holders is located on the axis of the sliding rod 7, the turntable 102 can be rotated by the drive component 101, so that each shoe holder can move sequentially to the axis position of the sliding rod 7. This allows for rapid switching of the shoes to be tested without the need for manual disassembly and re-fixing of the shoes. The operation is simple and efficient, thereby improving the testing efficiency.

[0052] In this embodiment, as Figures 1-4 As shown, a counterweight assembly 11 is provided at the other end of the slide rod 7. The counterweight assembly 11 includes a buffer sleeve 1101, a locking block 1102, an embedding groove 1103, and a plurality of annular counterweight blocks 1104. The buffer sleeve 1101 is fixed to the outside of the other end of the slide rod 7, the locking block 1102 is fixed to the outside of the buffer sleeve 1101, and the embedding groove 1103 is opened on the outside of each counterweight block 1104. Each counterweight block 1104 is sleeved on the outside of the buffer sleeve 1101 through the embedding groove 1103. The opening width of the embedding groove 1103 is greater than the diameter of the buffer sleeve 1101, and the diameter of the buffer sleeve 1101 is greater than the diameter of the through hole.

[0053] By fixing a buffer sleeve 1101 to the outside of the other end of the slide bar 7 and setting its diameter to be larger than the through hole, the slide bar 7 is effectively prevented from completely falling out of the through hole of the suspension plate 6 when it falls freely, ensuring the stability and safety of the testing device. At the same time, a locking block 1102 and multiple ring-shaped counterweights 1104 are set on the outside of the buffer sleeve 1101, and the counterweights 1104 are detachably fitted on the outside of the buffer sleeve 1101 using the embedding groove 1103. The number of counterweights 1104 can be flexibly adjusted according to the testing requirements, thereby increasing the piercing force of the sharp object on the sole of the shoe and improving the flexibility of the test.

[0054] In this embodiment, as Figures 1-4 As shown, a guide assembly 12 is also provided on the outside of the slide rod 7. The guide assembly 12 includes a guide sleeve 1201, a first support rod 1202, and a second support rod 1203. The guide sleeve 1201 is sleeved on the outside of the slide rod 7. One end of the first support rod 1202 and the second support rod 1203 are respectively fixed to the outside of the guide sleeve 1201, and the other end of the first support rod 1202 and the second support rod 1203 are respectively fixed to both sides of the suspension plate 6.

[0055] A guide sleeve 1201 is set on the outside of the slide rod 7 to provide secondary guidance and positioning for the free fall path of the slide rod 7, effectively ensuring the stability of the falling trajectory of the slide rod 7, thereby improving the positional accuracy of the sharp object 8 piercing the sole of the shoe.

[0056] In this embodiment, as Figures 1-4 As shown, the drive unit 101 includes a drive motor, and each shoe rack includes a support rod 103 and a support plate 104. One end of the support rod 103 is fixed to the top of the turntable 102, and the bottom of one side of the support plate 104 near the end is fixed to the other end of the support rod 103. One of the support rods 103 is coaxial with the slide rod 7, so that the sole of the shoe faces upward and is then put on the support plate 104 through the shoe opening.

[0057] In this embodiment, as Figures 1-4 As shown, a locking rod 13 is fixedly connected to one end of the slide rod 7 that penetrates the through hole. By fixing the locking rod 13 to one end of the slide rod 7 that penetrates the through hole, it is possible to effectively prevent the sharp object 8 from coming out of the through hole of the suspension plate 6 when the slide rod 7 is pulled to raise the sharp object 8 to the predetermined height.

[0058] The specific working process of this utility model is as follows:

[0059] (1) Before testing, the shoes to be tested should be supported by a shoe rack.

[0060] First, place the shoe with the sole facing up, and then slip the shoe over the support plate 104 through the shoe opening.

[0061] (2) Position the raised shoe sole on the trajectory of the falling sharp object 8.

[0062] The turntable 102 is driven to rotate by a drive motor, so that one of the support rods 103 is coaxial with the slide rod 7.

[0063] (3) Conduct a puncture test on the sole of the shoe.

[0064] By using the traction rope 9 and the movable pulley 5 together, the sliding rod 7 can be pulled to raise the sharp object 8 to a predetermined height. After the traction rope 9 is released, the sharp object 8 will fall freely and impact the sole of the shoe, thus completing the puncture resistance test.

[0065] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
