TECHNICAL FIELD
[0001] The utility model relates to shoe sole detection equipment technical field, concretely is a shoe sole tension detection device. BACKGROUND
[0002] Shoes are indispensable consumables in people's daily life, usually shoes contain two parts of shoe sole and upper, the shoe sole is usually made of rubber, PU and other high-strength, wear-resistant materials, the material of shoe sole affects the product quality of shoes, and the shoe sole needs to be tension tested to provide important parameters for product design and process improvement.
[0003] When tension testing, the shoe sole manufacturing material needs to be pulled gradually until it is pulled off to test the material's bearing range, and the existing tension testing device usually exposes the testing area directly to facilitate the tester to clamp the sample, but some elastic materials are easy to burst out under the action of elastic inertia when they are finally broken, which threatens the safety of surrounding testers. UTILITY MODEL CONTENT
[0004] Therefore, the utility model aims at providing a shoe sole tension detection device to solve the technical problems in the background.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical scheme: a shoe sole tension detection device, comprising a workbench and a mounting frame, a double-head motor is installed inside the workbench, a first bevel gear is connected to the output end of the double-head motor, a lead screw is connected to each side of the workbench, a second bevel gear is connected to the bottom end of each of the two lead screws, a sliding frame is connected to the outer surface of the lead screw, a protective door is connected to one side of the sliding frame, a damping rod and a protective frame are installed at the bottom of the mounting frame, a first guide rod and a connecting rod are connected inside the mounting frame, a tension sensor is connected to the bottom end of the connecting rod through a nut, and a clamping assembly is connected to the bottom end of the first guide rod, the bottom end of the tension sensor and the middle of the top of the workbench.
[0006] Further, the two clamping assemblies comprise a fixed seat, a screw rod and a second guide rod are connected inside the fixed seat, and two clamping plates are connected to the outer surfaces of the screw rod and the second guide rod, and a crank handle is connected to one end of the screw rod.
[0007] When detecting the sample, the worker puts the sample between the two clamping plates, then shakes the crank handle to drive the screw rod to rotate, and guides it through the second guide rod, so that the two clamping plates move to clamp and fix the sample. Through the above-mentioned way, the two clamping assemblies clamp and fix the sample, so that the worker clamps the sample simply, quickly and more labor-saving.
[0008] Furthermore, the protective door abuts against the mounting bracket, and the mounting bracket is slidably connected to the workbench.
[0009] By adopting the above technical solution, during sample testing, the staff starts the dual-head motor. The output end of the dual-head motor drives the first bevel gear to rotate. Through the meshing of the first bevel gear and the second bevel gear, the second bevel gear drives the lead screw to rotate. Under the drive of the lead screw, the slide moves the protective door upward. When the protective door abuts against the mounting frame, the protective door moves the mounting frame upward, thereby causing the clamping assembly to move upward and pull the sample. The tensile force is measured by a tensile sensor. This achieves the goal of simultaneously testing the tensile force of the sample and shielding the test area with the protective door, preventing sample fragments from escaping and threatening the personal safety of surrounding test personnel, thus improving the safety of the device.
[0010] Furthermore, the first bevel gear meshes with the second bevel gear, and the diameter of the second bevel gear is larger than the diameter of the first bevel gear.
[0011] By adopting the above technical solution, the first bevel gear drives the second bevel gear to rotate under the output of the dual-head motor, thereby causing the lead screw to move the slide upward. By controlling the upward speed of the slide in a small-to-large manner, the inaccurate test data caused by the slide moving too fast is avoided.
[0012] Furthermore, both the connecting rod and the first guide rod are slidably connected to the mounting bracket.
[0013] By adopting the above technical solution, when the sample breaks, the clamping seat pushes the first guide rod and the tension sensor upward under the action of inertia, so that the first guide rod and the connecting rod slide within the mounting frame. The second guide rod and the connecting rod relieve the force on the clamping assembly, thereby avoiding damage to the tension sensor caused by impact and protecting the tension sensor.
[0014] Furthermore, the damping rods are provided in four groups, and the four groups of damping rods are distributed in a rectangular array.
[0015] By adopting the above technical solution, when the inertial force is large, the fixed seat contacts the bottom end of the damping rod under the action of inertia, causing the damping rod to be compressed. The damping rod further relieves the force on the clamping component. The four sets of damping rods are distributed in a rectangular array to disperse the impact force and improve the force relief effect.
[0016] Furthermore, both the bottom of the damping rod and the bottom of the protective frame are connected to soft pads, and the soft pads are made of rubber.
[0017] By adopting the above technical solution, when the inertial force is too large, the fixed seat will completely compress the damping rod under the action of inertia. At this time, the tension sensor enters the protective frame, and the bottom of the protective frame contacts the fixed seat. The protective frame protects the damping rod while relieving the force. At the same time, the soft pad buffers the contact between the damping rod and the protective frame and the fixed seat, thereby avoiding hard contact between the damping rod and the protective frame and the fixed seat, thus extending the service life of the damping rod and other mechanisms.
[0018] Furthermore, the outer surface of the protective door is provided with an observation window.
[0019] By adopting the above technical solution, the protective door moves the mounting frame upward under the drive of the carriage, thereby causing the clamping component to move upward and pull the sample. The internal situation of the working area can be observed through the observation window so that the operator can grasp the status of the sample.
[0020] Furthermore, a scale is installed on the outer surface of the workbench, and a pointer is connected to one side of the carriage, with the pointer corresponding to the position of the scale.
[0021] By adopting the above technical solution, the mounting bracket moves the pointer upward under the action of the protective door. By observing the position indicated by the pointer on the scale, the staff can grasp the length of the sample being pulled and record the data.
[0022] In summary, the present invention has the following main advantages:
[0023] 1. This utility model, by setting up a slide and a protective door, allows for sample testing. When the operator starts the dual-head motor, the output end of the dual-head motor drives the first bevel gear to rotate. Through the meshing of the first bevel gear and the second bevel gear, the second bevel gear drives the lead screw to rotate. Under the drive of the lead screw, the slide moves the protective door upward. When the protective door abuts against the mounting frame, the protective door moves the mounting frame upward, thereby causing the clamping assembly to move upward and pull the sample. The tensile force is measured by a tensile force sensor. Thus, while testing the tensile force of the sample, the protective door shields the test area, preventing fragments from flying out and threatening the personal safety of the surrounding test personnel if the sample breaks, thereby improving the safety of the device.
[0024] 2. This utility model, by setting up a protective frame and a soft pad, when the inertial force is too large, the fixed seat completely compresses the damping rod, and the protective frame protects the damping rod while relieving the force. At the same time, the soft pad buffers the contact between the damping rod and the protective frame and the fixed seat, thereby avoiding hard contact between the damping rod and the protective frame and the fixed seat, thus extending the service life of the damping rod and other mechanisms.

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.
[0032] The embodiments of this utility model will be described below based on its overall structure.
[0033] Example 1: A shoe sole tensile testing device, such as Figures 1-5As shown, the device includes a workbench 1 and a mounting frame 7. A dual-head motor 2 is installed inside the workbench 1. The output end of the dual-head motor 2 is connected to a first bevel gear 15. Lead screws 3 are connected to both sides of the workbench 1, and the bottom ends of both lead screws 3 are connected to second bevel gears 16. A slide 4 is connected to the outer surface of the lead screws 3, and a protective door 5 is connected to one side of the slide 4. A damping rod 12 and a protective frame 13 are installed at the bottom of the mounting frame 7. A first guide rod 9 and a connecting rod 8 are connected inside the mounting frame 7. A tension sensor 10 is connected to the bottom end of the connecting rod 8 via a nut. Clamping assemblies 11 are connected to the bottom end of the tension sensor 10, the bottom end of the first guide rod 9, and the middle of the top of the workbench 1. The two clamping assemblies 11 include a fixed base 1. 101. The fixing base 1101 is internally connected to a screw 1103 and a second guide rod 1102. The outer surfaces of the screw 1103 and the second guide rod 1102 are connected to two clamping plates 1104. One end of the screw 1103 is connected to a crank handle 1105. When testing the sample, the operator places the sample between the two clamping plates 1104 and then cranks the crank handle 1105 to drive the screw 1103 to rotate. Guided by the second guide rod 1102, the two clamping plates 1104 move to clamp and fix the sample. In this way, the two clamping components 11 clamp and fix the sample, making it simple, quick and labor-saving for the operator to clamp the sample.
[0034] See Figures 1-4 In the above embodiment, the protective door 5 abuts against the mounting frame 7, and the mounting frame 7 is slidably connected to the workbench 1. When testing the sample, the operator starts the double-headed motor 2. The output end of the double-headed motor 2 drives the first bevel gear 15 to rotate. Through the meshing of the first bevel gear 15 and the second bevel gear 16, the second bevel gear 16 drives the lead screw 3 to rotate. Under the drive of the lead screw 3, the slide 4 drives the protective door 5 to move upward. When the protective door 5 abuts against the mounting frame 7, the protective door 5 drives the mounting frame 7 to move upward, thereby causing the clamping assembly 11 to move upward and pull the sample. The tensile force sensor 10 measures the force, thereby achieving the goal of shielding the test area through the protective door 5 while testing the sample tensile force, preventing sample fragments from breaking out and threatening the personal safety of the surrounding test personnel, and improving the safety of the device.
[0035] See Figure 3 and Figure 4 In the above embodiment, the first bevel gear 15 meshes with the second bevel gear 16, and the diameter of the second bevel gear 16 is larger than the diameter of the first bevel gear 15. Driven by the output end of the dual-head motor 2, the first bevel gear 15 drives the second bevel gear 16 to rotate, thereby causing the lead screw 3 to drive the slide 4 to move upward. By controlling the upward speed of the slide 4 in a small-to-large manner, the upward speed of the slide 4 is avoided from being too fast and causing inaccurate test data.
[0036] See Figures 1-5In the above embodiment, both the connecting rod 8 and the first guide rod 9 are slidably connected to the mounting frame 7. When the sample breaks, under the action of inertia, the clamping seat pushes the first guide rod 9 and the tension sensor 10 upward, so that the first guide rod 9 and the connecting rod 8 slide within the mounting frame 7. The clamping assembly 11 is unloaded through the second guide rod 1102 and the connecting rod 8, thereby avoiding damage to the tension sensor 10 caused by impact and protecting the tension sensor 10.
[0037] See Figure 2 , Figure 3 , Figure 4 and Figure 5 In the above embodiment, there are four sets of damping rods 12, and the four sets of damping rods 12 are distributed in a rectangular array. When the inertial force is large, the fixed seat 1101 contacts the bottom end of the damping rod 12 under the action of inertia, so that the damping rod 12 is compressed. The damping rod 12 further relieves the force on the clamping assembly 11. The rectangular array of the four sets of damping rods 12 can disperse the impact force and improve the force relief effect.
[0038] See Figure 3 and Figure 5 In the above embodiment, both the bottom of the damping rod 12 and the bottom of the protective frame 13 are connected to soft pads 14, which are made of rubber. When the inertial force is too large, under the action of inertia, the fixed seat 1101 completely compresses the damping rod 12. At this time, the tension sensor 10 enters the interior of the protective frame 13, and the bottom of the protective frame 13 contacts the fixed seat 1101. The protective frame 13 protects the damping rod 12 while relieving the force. At the same time, the soft pads 14 buffer the damping rod 12 and the protective frame 13 when they contact the fixed seat 1101, thereby avoiding hard contact between the damping rod 12 and the protective frame 13 and the fixed seat 1101, thus extending the service life of the damping rod 12 and other mechanisms.
[0039] See Figure 1 and Figure 2 In the above embodiment, the outer surface of the protective door 5 is provided with an observation window 6. Driven by the slide 4, the protective door 5 drives the mounting bracket 7 to move upward, thereby causing the clamping assembly 11 to move upward and pull the sample. The observation window 6 allows the operator to observe the internal conditions of the working area so that the operator can understand the sample status.
[0040] Example 2: To facilitate the recording of the sample's fracture length by testing personnel, Example 2 is an improvement upon Example 1. (See attached document.) Figure 1 , Figure 2 and Figure 4A scale 18 is installed on the outer surface of the workbench 1. A pointer 17 is connected to one side of the slide 4, and the pointer 17 corresponds to the scale 18. Under the action of the protective door 5, the mounting frame 7 moves the pointer 17 upward. By observing the position indicated by the pointer 17 on the scale 18, the staff can grasp the length of the sample being pulled and record the data.
[0041] The implementation principle of this utility model is as follows: The operator places the sample between two clamping plates 1104, then shakes the handle 1105 to drive the screw 1103 to rotate. Guided by the second guide rod 1102, the two clamping plates 1104 move to clamp and fix the sample. In this way, the two clamping components 11 clamp and fix the sample. After fixing, the operator starts the double-head motor 2. The output end of the double-head motor 2 drives the first bevel gear 15 to rotate. Through the meshing of the first bevel gear 15 and the second bevel gear 16, the second bevel gear 16 drives the lead screw 3 to rotate. Driven by the lead screw 3, guided by the first guide rod 9, the slide 4 drives the protective door 5 to move upward. When the protective door 5 abuts against the mounting frame 7, the protective door 5 drives the mounting frame 7 to move upward, thereby driving the clamping components 11 to move upward and pull the sample. The force is measured by the tension sensor 10. When the sample breaks, under the action of inertia, the clamping seat pushes the first guide rod 9 and the tension sensor 10 upward, so that the first guide rod 9 and the connecting rod 8 slide within the mounting frame 7. The first guide rod 9 and the connecting rod 8 relieve the force on the clamping assembly 11, preventing the tension sensor 10 from being damaged by impact. When the inertial force is large, the fixed seat 1101 contacts the bottom end of the damping rod 12, causing the damping rod 12 to be compressed. The damping rod 12 further relieves the force on the clamping assembly 11, improving the force relief effect. When the inertial force is too large, the fixed seat 1101 completely compresses the damping rod 12. At this time, the tension sensor 10 enters the interior of the protective frame 13. The bottom of the protective frame 13 contacts the fixed seat 1101. The protective frame 13 protects the damping rod 12 while relieving the force.
