Description

Technical Field

[0001] This utility model relates to the field of pull-out testing technology, and specifically to a pull-out testing device. Background Technology

[0002] Handheld cleaning devices are a type of cleaning device that requires manual operation, such as floor scrubbers, mops, and handheld vacuum cleaners. Handheld cleaning devices have a grip mechanism that allows the operator to hold the device for easy cleaning.

[0003] During the product manufacturing process, a pull-out force test is required for handheld cleaning devices. This test is a crucial product quality test, as the results reflect the secure installation of the grip mechanism and directly impact the safety and reliability of the handheld cleaning device.

[0004] Traditional pull-out testing requires manual pulling of the grip mechanism of the handheld cleaning device. However, manual pulling is susceptible to variations in physical strength and operating habits among different testers, and even the same tester's physical and mental state can differ at different times. This reduces the stability of the pull-out testing process, leading to decreased accuracy of the results. Therefore, increasing the automation level of pull-out testing and avoiding manual intervention is crucial for improving the accuracy of the results. Utility Model Content

[0005] The purpose of this invention is to improve the automation level of pull-out testing, avoid manual pull-out testing, and thus improve the accuracy of pull-out test results.

[0006] To achieve the above objectives, this utility model provides a pull-out testing device, which includes a support mechanism, a positioning mechanism, a pull-out mechanism, a tension / compression sensor, and a clamping mechanism. The positioning mechanism is connected to the support mechanism and is configured to fix or release the non-grip mechanism of a handheld cleaning device. The clamping mechanism is connected to the pull-out mechanism via the tension / compression sensor and is configured to clamp or release the gripping mechanism of the handheld cleaning device. The pull-out mechanism is connected to the support mechanism and can be driven by the tension / compression sensor to move linearly along a direction away from or towards the positioning mechanism to pull out or release the gripping mechanism. The tension / compression sensor is used to connect to a data processing device to transmit tensile force data to the data processing device.

[0007] In some embodiments, the pulling mechanism includes a pulling driver, the fixing part of which is fixedly connected to the support mechanism, and the driving actuator of which is connected to the clamping mechanism via a tension / compression sensor. The pulling driver can drive the clamping mechanism to reciprocate linearly via the tension / compression sensor to pull the gripping mechanism or release the pull.

[0008] In some embodiments, the drive actuator of the pull driver is equipped with a connecting plate, and the tension / compression sensor is connected to the connecting plate.

[0009] In some embodiments, the clamping mechanism includes a clamping driver and two clamping arms. The fixing part of the clamping driver is connected to the drive actuator of the pulling mechanism. The clamping driver can drive the two clamping arms to move closer or further apart to clamp or release the gripping mechanism of the handheld cleaning device.

[0010] In some embodiments, the clamping arm has a clamping groove on the side facing the gripping mechanism that can accommodate the gripping mechanism.

[0011] In some embodiments, a mounting platform is provided on the side of the clamping driver's fixing part facing the support mechanism, and the tension / compression sensor is connected to the mounting platform.

[0012] In some embodiments, the positioning mechanism is configured to press, position, or release at least one of the top of the main body of the handheld cleaning device, the outer periphery of the main body of the handheld cleaning device, and the cleaning execution portion of the handheld cleaning device.

[0013] In some embodiments, the pull-out testing device further includes a guide mechanism connected to the support mechanism; the positioning mechanism includes a first clamping mechanism configured to clamp or release the top of the main body of the handheld cleaning device; at least one of the clamping actuator and the clamping mechanism of the first clamping mechanism reciprocates via the guide mechanism.

[0014] In some embodiments, the guiding mechanism includes a first movable plate, two guide rails and two first sliders. The two guide rails are disposed on the support mechanism and extend vertically. A pulling mechanism is disposed between the two guide rails. The two first sliders are slidably mounted on the two guide rails respectively. The two first sliders are connected to the first movable plate. A clamping mechanism is connected to the first movable plate.

[0015] In some embodiments, the guide mechanism further includes a second movable plate and two second sliders, the two second sliders being slidably mounted on two guide rails respectively, the two second sliders being connected to the second movable plate, the clamping execution part of the first clamping mechanism being connected to the second movable plate, and the clamping drive part of the first clamping mechanism being disposed between the two guide rails.

[0016] The above-mentioned technical solution of this utility model has the following beneficial effects: The positioning mechanism can position and fix the non-grip mechanism of the handheld cleaning device, preventing it from shaking during the pull-out test. The pull-out mechanism drives the clamping mechanism to move linearly away from the positioning mechanism, so that the clamping mechanism pulls on the gripping mechanism. Tension and pressure sensors installed on the pull-out mechanism and the clamping mechanism can detect the pull-out force applied by the pull-out mechanism, and further transmit this pull-out force data to the data processing device in real time. Therefore, by adopting the pull-out testing device of this invention, automatic pull-out testing of handheld cleaning devices can be achieved, improving the degree of automation, avoiding manual pull-out testing, increasing the stability of the pull-out testing process, and thus improving the accuracy of the pull-out test results.

[0019] The features and exemplary embodiments of various aspects of this utility model will now be described in detail. To make the objectives, technical solutions, and advantages of this utility model clearer, the following description, in conjunction with the accompanying drawings and specific embodiments, will provide a further detailed description. It should be understood that the specific embodiments described herein are intended only to explain this utility model and not to limit it. For those skilled in the art, this utility model can be implemented without some of these specific details. The following description of the embodiments is merely to provide a better understanding of this utility model by illustrating examples of it.

[0020] To make the solution of this utility model clear, this utility model will first provide a brief description of the handheld cleaning device 7. For example... Figure 1 As shown, the handheld cleaning device 7 includes a gripping mechanism 71 and a non-grip mechanism 72. The gripping mechanism 71 is used by the operator to hold and control the non-grip mechanism 72. The non-grip mechanism 72 further includes a main body 721 and a cleaning execution part 722. The main body 721 has a waste collection bin and a suction device, and is relatively long. The cleaning execution part 722 is connected to the bottom of the main body 721. The gripping mechanism 71 is connected to the main body 721, and the pull-out test mainly tests the strength of the connection between the gripping mechanism 71 and the main body 721. The cleaning execution part 722 can mop or suction the surface to be cleaned, such as the floor or wall.

[0021] like Figures 2 to 6As shown, this utility model provides a pull-out testing device, which includes a support mechanism 1, a positioning mechanism 2, a pull-out mechanism 3, a tension / compression sensor 4, and a clamping mechanism 5. The positioning mechanism 2 is connected to the support mechanism 1 and is configured to fix or release the non-grip mechanism 72 of a handheld cleaning device 7. The clamping mechanism 5 is connected to the pull-out mechanism 3 via the tension / compression sensor 4 and is configured to clamp or release the gripping mechanism 71 of the handheld cleaning device 7. The pull-out mechanism 3 is connected to the support mechanism 1 and can be driven by the tension / compression sensor 4 to move the clamping mechanism 5 linearly in a direction away from or towards the positioning mechanism 2, thereby pulling out or releasing the gripping mechanism 71. The tension / compression sensor 4 is used for signal connection with a data processing device to transmit tensile force data to the data processing device.

[0022] Specifically, when a pull-out force test is required, the handheld cleaning device 7 is first installed onto the pull-out testing device. The non-grip mechanism 72 of the handheld cleaning device 7 is located at the positioning mechanism 2, and the gripping mechanism 71 of the handheld cleaning device 7 is located at the clamping mechanism 5. Then, the positioning mechanism 2 positions and fixes the non-grip mechanism 72 of the handheld cleaning device 7 to prevent it from shaking during the pull-out test. Next, the clamping mechanism 5 clamps the gripping mechanism 71. Then, the pull-out mechanism 3 drives the clamping mechanism 5 to move linearly away from the positioning mechanism 2, at which point the clamping mechanism 5 applies a pull to the gripping mechanism 71. During the movement of the clamping mechanism 5 driven by the pull-out mechanism 3, since the clamping mechanism 5 is connected to the pull-out mechanism 3 via a tension / compression sensor 4, the tension / compression sensor 4 can detect the pull-out force applied by the pull-out mechanism 3 and can send this pull-out force data to the data processing device in real time. The data processing device further processes the pull-out force data into a visual image for the tester's reference. When the pull-out test is complete, the pull-out mechanism 3 drives the clamping mechanism 5 to move linearly towards the positioning mechanism 2. Then, the clamping mechanism 5 releases the gripping mechanism 71, and then the positioning mechanism 2 releases the non-grip mechanism 72 of the handheld cleaning device 7 (that is, the positioning mechanism 2 releases the non-grip mechanism 72 from its positioning). Finally, the handheld cleaning device 7 is removed from the pull-out test device. If it is necessary to test the next handheld cleaning device 7, the above operation process can be repeated.

[0023] In this embodiment, the positioning mechanism 2 can position and fix the non-grip mechanism 72 of the handheld cleaning device 7, preventing the non-grip mechanism 72 from shaking during the pull-out test; the pull-out mechanism 3 drives the clamping mechanism 5 to move linearly away from the positioning mechanism 2, so that the clamping mechanism 5 pulls on the gripping mechanism 71; the tension and pressure sensors 4 provided on the pull-out mechanism 3 and the clamping mechanism 5 can detect the pull-out force applied by the pull-out mechanism 3, and the tension and pressure sensors 4 further send the pull-out force data to the data processing device in real time. Therefore, by using the pull-out testing device of this utility model, the handheld cleaning device 7 can be automatically tested, the degree of automation is improved, manual pull-out testing is avoided, the stability of the pull-out testing process is increased, and thus the accuracy of the pull-out test results is improved.

[0024] It should be noted that the tension / compression sensor 4 is a common sensor in the field. The tension / compression sensor 4 is not an improvement of this utility model. Those skilled in the art can refer to the prior art. This utility model will not elaborate further.

[0025] In some embodiments, the clamping mechanism 5 and the pulling mechanism 3 are disposed above the positioning mechanism 2. When the pulling mechanism 3 drives the clamping mechanism 5 to move upward, it pulls the gripping mechanism 71; when the pulling mechanism 3 drives the clamping mechanism 5 to move downward, it releases the gripping mechanism 71 from the pull.

[0026] like Figures 2 to 7 As shown, in some embodiments of this utility model, the pulling mechanism 3 includes a pulling driver 31. The fixing part of the pulling driver 31 is fixedly connected to the support mechanism 1, and the driving execution part of the pulling driver 31 is connected to the clamping mechanism 5 through the tension and pressure sensor 4. The pulling driver 31 can drive the clamping mechanism 5 to reciprocate linearly through the tension and pressure sensor 4 to pull the gripping mechanism 71 or release the pulling.

[0027] Specifically, when the drive actuator of the pull driver 31 drives the clamping mechanism 5 to move upward, the clamping mechanism 5 can pull the gripping mechanism 71 upward, thereby pulling the gripping mechanism 71. When the drive actuator of the pull driver 31 drives the clamping mechanism 5 to move downward, the clamping mechanism 5 no longer pulls the gripping mechanism 71 upward, thereby releasing the pull on the gripping mechanism 71.

[0028] It should be noted that the pull-out actuator 31 can be any device that meets the requirements of this utility model, and this utility model is not limited thereto. For example, the pull-out actuator 31 can be a cylinder or a hydraulic cylinder, etc. Preferably, the pull-out actuator 31 is a common ultra-thin cylinder with a guide rod or a dual-shaft dual-rod cylinder, etc.; wherein, the fixing part of the pull-out actuator 31 is the cylinder barrel of this type of cylinder, and the driving actuation part of the pull-out actuator 31 is the piston rod of this type of cylinder.

[0029] It should also be noted that the pulling mechanism 3 can adopt any other structural form that can meet the usage requirements of this utility model, and this utility model is not limited thereto. For example, the pulling mechanism 3 includes a winch, which is installed on the support mechanism 1, and the connecting rope of the winch is connected to the clamping mechanism 5.

[0030] like Figure 8 As shown, in some embodiments of this utility model, the drive actuator of the pull driver 31 is equipped with a connecting plate 32, and the tension / compression sensor 4 is connected to the connecting plate 32.

[0031] Specifically, a connecting plate 32 is installed on the drive actuator of the pull driver 31, and then the tension / compression sensor 4 is connected to the connecting plate 32, thereby connecting the tension / compression sensor 4 to the drive actuator of the pull driver 31.

[0032] like Figures 2 to 7 As shown, in some embodiments of the present invention, the clamping mechanism 5 includes a clamping driver 51 and two clamping arms 52. The fixing part of the clamping driver 51 is connected to the driving execution part of the pulling mechanism 3. The clamping driver 51 can drive the two clamping arms 52 to move closer or further away from each other to clamp or release the gripping mechanism 71 of the handheld cleaning device 7.

[0033] Specifically, when the clamping driver 51 drives the two clamping arms 52 to move closer together, the two clamping arms 52 can clamp and fix the gripping mechanism 71; when the clamping driver 51 drives the two clamping arms 52 to move away from each other, the two clamping arms 52 can release the gripping mechanism 71, thereby releasing the gripping mechanism 71. Preferably, the clamping driver 51 can drive the two clamping arms 52 to move closer or further apart horizontally.

[0034] It should be noted that the clamping actuator 51 can be any structural form that meets the usage requirements of this utility model, and this utility model is not limited thereto. For example, the clamping actuator 51 is a common finger cylinder in the art, with two clamping arms 52 respectively connected to the two piston rods of the finger cylinder; the two piston rods of the finger cylinder can extend or retract synchronously to drive the two clamping arms 52 to move away from or towards each other. The cylinder barrel of the finger cylinder is the fixing part of the clamping actuator 51, and the piston rod of the finger cylinder is the driving execution part of the clamping actuator 51. As another example, the clamping actuator 51 includes two common dual-axis dual-rod cylinders in the art, with the piston rods of the two dual-axis dual-rod cylinders facing opposite directions, and the two clamping arms 52 respectively connected to the piston rods of the two dual-axis dual-rod cylinders.

[0035] It should be noted that the gripping mechanism 71 has a rod portion 711 and a grip portion 712. The grip portion 712 is connected to the main body portion 721 via the rod portion 711. The grip portion 712 differs in structure from the rod portion 711; it is typically an irregularly shaped handle, pull ring, or handle. To improve the stability of the clamping gripping mechanism 71, the two clamping arms 52 can clamp onto the grip portion 712, or clamp onto the portion of the rod portion 711 adjacent to the grip portion 712 (see reference). Figures 2 to 4 ).

[0036] like Figure 7 As shown, in some embodiments of this utility model, the clamping arm 52 is provided with a clamping groove 53 on the side facing the gripping mechanism 71, which can accommodate the gripping mechanism 71.

[0037] Specifically, when the clamping driver 51 drives the two clamping arms 52 to clamp the gripping mechanism 71 of the handheld cleaning device 7, the gripping mechanism 71 is clamped in the two clamping grooves 53, at which time the groove walls of the clamping grooves 53 are in close contact with the outer surface of the gripping mechanism 71. By setting the clamping grooves 53, the structure of the clamping arms 52 can be more adapted to the outer periphery of the gripping mechanism 71, thereby facilitating the clamping of the gripping mechanism 71.

[0038] like Figure 8 As shown, in some embodiments of this utility model, the clamping driver 51 has a mounting platform 54 on the side facing the support mechanism 1, and the tension / compression sensor 4 is connected to the mounting platform 54, thereby fixing the tension / compression sensor 4 to the clamping driver 51.

[0039] In some embodiments, the mounting platform 54 is disposed on the second movable plate 64.

[0040] In some embodiments of the present invention, the positioning mechanism 2 is configured to press and position or release at least one of the top of the main body portion 721 of the handheld cleaning device 7, the outer periphery of the main body portion 721 of the handheld cleaning device 7, and the cleaning execution portion 722 of the handheld cleaning device 7, so as to position and fix the non-grip mechanism 72 of the handheld cleaning device 7.

[0041] like Figures 2 to 7 as well as Figure 9 As shown, in some embodiments of this utility model, the positioning mechanism 2 includes a first pressing mechanism 21 disposed below the clamping mechanism 5. The first pressing mechanism 21 is configured to press or release the top of the main body portion 721 of the handheld cleaning device 7. The first pressing mechanism 21 can press from the top of the main body portion 721, thereby improving the pressing and fixing effect.

[0042] like Figures 2 to 7 as well as Figure 9As shown, in some embodiments of this utility model, the first pressing mechanism 21 includes a first pressing driver 211 and a pressing plate 212. The fixing part of the first pressing driver 211 is connected to the support mechanism 1. The first pressing driver 211 is disposed below the clamping mechanism 5. The driving execution part of the first pressing driver 211 is connected to the pressing plate 212. The first pressing driver 211 can drive the pressing plate 212 to move vertically to press or release the top of the main body 721 of the handheld cleaning device 7.

[0043] Specifically, the first clamping actuator 211 can drive the clamping plate 212 to move downward, so that the clamping plate 212 can press down on the top of the main body 721, thereby clamping and fixing the main body 721. The first clamping actuator 211 can drive the clamping plate 212 to move upward, so that the clamping plate 212 moves away from the top of the main body 721, and the main body 721 of the handheld cleaning device 7 is released, that is, the main body 721 is released from clamping and fixing.

[0044] It should be noted that the first clamping actuator 211 can be any device that meets the requirements of this utility model, and this utility model is not limited thereto. For example, the first clamping actuator 211 can be a cylinder or a hydraulic cylinder, etc. Preferably, the first clamping actuator 211 is a common ultra-thin cylinder with a guide rod, a double-shaft double-rod cylinder, or a standard cylinder, etc.; wherein, the fixing part of the first clamping actuator 211 is the cylinder barrel of this type of cylinder, and the driving actuation part of the first clamping actuator 211 is the piston rod of this type of cylinder.

[0045] like Figure 9 As shown, in some embodiments of this utility model, the side of the pressing plate 212 facing the gripping mechanism 71 is provided with a relief groove 213 that can avoid the gripping mechanism 71.

[0046] Specifically, when the clamping plate 212 clamps the main body 721 of the handheld cleaning device 7, the gripping mechanism 71 passes through the clearance groove 213. By providing the clearance groove 213, the gripping mechanism 71 can be prevented from interfering with the clamping plate 212, making it easier for the clamping plate 212 to clamp the main body 721 of the handheld cleaning device 7.

[0047] like Figures 2 to 7 as well as Figure 10 As shown, in some embodiments of this utility model, the positioning mechanism 2 further includes a second pressing mechanism 22 disposed below the clamping mechanism 5. The second pressing mechanism 22 is configured to press or release the outer periphery of the main body portion 721 of the handheld cleaning device 7. The second pressing mechanism 22 can further press and fix the main body portion 721 of the handheld cleaning device 7 to prevent the main body portion 721 from shaking.

[0048] like Figures 2 to 7 as well as Figure 10 As shown, in some embodiments of this utility model, the second pressing mechanism 22 includes a second pressing driver 221, a first pressing arm 222, and a positioning seat 223. The positioning seat 223 is connected to the support mechanism 1. The side of the positioning seat 223 facing the main body 721 is provided with a positioning groove 224 that can accommodate the main body 721. The fixing part of the second pressing driver 221 is connected to the support mechanism 1. The first pressing arm 222 is connected to the driving execution part of the second pressing driver 221. The second pressing driver 221 can drive the first pressing arm 222 to move toward or away from the main body 721 to press the main body 721 into the positioning groove 224 or release the main body 721.

[0049] Specifically, when a pull-out test is required, the main body 721 of the handheld cleaning device 7 is placed in the positioning groove 224 of the positioning seat 223. Then, the second clamping driver 221 drives the first clamping arm 222 to move towards the main body 721. The first clamping arm 222 can clamp and position the main body 721 in the positioning groove 224, thereby fixing the main body 721 in a preset position. After the main body 721 is fixed in the preset position, the first clamping mechanism 21 further clamps and fixes the top of the main body 721, thereby facilitating the pull-out of the gripping mechanism 71. After the pull-out test is completed, the second clamping driver 221 drives the first clamping arm 222 to move in the opposite direction. The first clamping arm 222 moves away from the main body 721 and releases the main body 721, thus releasing the clamping and positioning of the main body 721.

[0050] It should be noted that the second clamping actuator 221 can be any device that meets the requirements of this utility model, and this utility model is not limited thereto. For example, the second clamping actuator 221 can be a cylinder or a hydraulic cylinder, etc. Preferably, the positioning actuator can be a rotary clamping cylinder commonly used in the art; wherein, the fixing part of the second clamping actuator 221 is the cylinder barrel of this type of cylinder, and the driving actuation part of the second clamping actuator 221 is the piston rod of this type of cylinder.

[0051] like Figures 2 to 7 as well as Figure 11 As shown, in some embodiments of the present invention, the positioning mechanism 2 further includes a third pressing mechanism 23 disposed below the clamping mechanism 5, the third pressing mechanism 23 being configured to press or release the cleaning execution part 722 of the handheld cleaning device 7.

[0052] Specifically, by setting the third clamping mechanism 23, the cleaning execution part 722 can be further clamped and fixed. At the same time, the main body part 721 can be clamped and fixed by the first clamping mechanism 21 and the second clamping mechanism 22. Therefore, the entire non-grip mechanism 72 of the handheld cleaning device 7 is clamped and fixed, so that the entire non-grip mechanism 72 of the handheld cleaning device 7 will not shake, which helps to improve the accuracy of the pull-out test structure.

[0053] In some embodiments of this utility model, the third pressing mechanism 23 is connected to the support mechanism 1 so that the third pressing mechanism 23 and the support mechanism 1 are integrated into one unit, thereby enhancing the stability of the third pressing mechanism 23.

[0054] like Figures 2 to 7 as well as Figure 11 As shown, in some embodiments of this utility model, the third pressing mechanism 23 includes a support base 231, a third pressing driver 232, and a second pressing arm 233. The support base 231 is disposed below the clamping mechanism 5. The top of the support base 231 is provided with a receiving groove 234 for accommodating the cleaning execution part 722. The fixing part of the third pressing driver 232 is connected to the support base 231. The second pressing arm 233 is connected to the driving execution part of the third pressing driver 232. The third pressing driver 232 can drive the second pressing arm 233 to move toward or away from the cleaning execution part 722, so as to press the cleaning execution part 722 into the receiving groove 234 or release the cleaning execution part 722.

[0055] Specifically, when a pull-out test is required, the cleaning execution part 722 of the handheld cleaning device 7 is placed into the receiving groove 234 of the support base 231. Then, the third clamping driver 232 drives the second pressure arm 233 to move towards the cleaning execution part 722, so that the second pressure arm 233 clamps and positions the cleaning execution part 722 in the receiving groove 234. At the same time, the second clamping mechanism 22 clamps and fixes the main body part 721 in the positioning groove 224 of the positioning base 223, and the first clamping mechanism 21 clamps and fixes the top of the main body part 721. At this time, the entire non-grip mechanism 72 of the handheld cleaning device 7 is firmly fixed, and the entire non-grip mechanism 72 of the handheld cleaning device 7 will not shake, which helps to improve the accuracy of the pull-out test results. Preferably, the support base 231 is fixedly connected to the bottom of the support column 11.

[0056] It should be noted that the third clamping actuator 232 can be any device that meets the requirements of this utility model, and this utility model is not limited thereto. For example, the third clamping actuator 232 can be a cylinder or a hydraulic cylinder, etc. Preferably, the third clamping actuator 232 can be a rotary clamping cylinder commonly used in the art; wherein, the fixing part of the third clamping actuator 232 is the cylinder barrel of this type of cylinder, and the driving actuation part of the second clamping actuator 221 is the piston rod of this type of cylinder.

[0057] In some embodiments, the support base 231 is connected to the support mechanism 1, for example, the support base 231 is connected to the support column 11.

[0058] It should be noted that the third pressing mechanism 23 can also be any other structural form that can meet the usage requirements of this utility model. This utility model does not limit it. For example, the third pressing mechanism 23 includes a cylinder, a pressure plate and a support frame. The fixed part of the cylinder is installed on the support frame, the piston rod of the cylinder is downward, and the pressure plate is connected to the piston rod of the cylinder. The cylinder can drive the pressure plate to move vertically. When the cylinder drives the pressure plate to move downward, the pressure plate can press the cleaning execution part 722 of the handheld cleaning device 7.

[0059] In some embodiments, the clamping mechanism 5, the first pressing mechanism 21, the second pressing mechanism 22, and the third pressing mechanism 23 are distributed sequentially from top to bottom. The pulling mechanism 3 can be disposed above or below the clamping mechanism 5, and this utility model does not impose any limitation.

[0060] like Figure 5 and Figure 6 As shown, in some embodiments of this utility model, the support mechanism 1 includes a support column 11 and a support plate 12. The first pressing mechanism 21, the pulling mechanism 3 and the clamping mechanism 5 of the positioning mechanism 2 are connected to the same side of the support plate 12, and the support plate 12 is connected to the support column 11.

[0061] Specifically, the support column 11 can support the support plate 12 so that the support plate 12 reaches a preset height, thereby facilitating the installation of the first pressing mechanism 21, the pulling mechanism 3 and the clamping mechanism 5.

[0062] In some embodiments, the fixing part of the second clamping driver 221 may be connected to the bottom of the support plate 12 or the top of the support column 11. In some embodiments, a bracket 14 is provided between the support column 11 and the support plate 12, and the fixing part of the second clamping driver 221 is fixedly connected to the bracket 14.

[0063] It should be noted that the support mechanism 1 can also be any other structural form that meets the requirements of this utility model, and this utility model is not limited thereto. For example, the support mechanism 1 can be a frame composed of multiple connecting rods.

[0064] It should be noted that the support mechanism 1 (e.g., support column 11) can be installed on the ground or the surface of the tooling platform, etc.

[0065] like Figure 5 and Figure 6 As shown, in some embodiments of this utility model, the support plate 12 is provided with at least one weight reduction hole 13, one of which can expose the tension and compression sensor 4, thereby reducing the weight of the support mechanism 1 and facilitating the connection of the tension and compression sensor 4 to the data processing device.

[0066] like Figure 5 and Figure 6 As shown, in some embodiments of this utility model, the pull-out testing device further includes a guide mechanism 6, which is connected to the support mechanism 1; the positioning mechanism 2 includes a first pressing mechanism 21, which is configured to press or release the top of the main body 721 of the handheld cleaning device 7; at least one of the pressing execution part of the first pressing mechanism 21 and the clamping mechanism 5 reciprocates through the guide mechanism 6, so that at least one of the clamping mechanism 5 and the pressing execution part of the first pressing mechanism 21 improves the movement stability.

[0067] like Figure 5 and Figure 6 As shown, in some embodiments of this utility model, the guide mechanism 6 includes a first movable plate 61, two guide rails 62 and two first sliders 63. The two guide rails 62 are disposed on the support mechanism 1 and extend vertically. The pulling mechanism 3 is disposed between the two guide rails 62. The two first sliders 63 are slidably mounted on the two guide rails 62 respectively. The two first sliders 63 are connected to the first movable plate 61. The clamping mechanism 5 is connected to the first movable plate 61.

[0068] Specifically, when the pulling mechanism 3 drives the clamping mechanism 5 to move, the clamping mechanism 5 can move vertically along the two guide rails 62 via the first moving plate 61 and the two first sliders 63. Through the cooperation between the first sliders 63 and the guide rails 62, the pulling mechanism 3 can only move linearly along the guide rails 62, and the clamping mechanism 5 will only pull on the gripping mechanism 71 of the handheld cleaning device 7 in a fixed direction without causing shaking, thereby improving the accuracy of the pulling test results.

[0069] like Figure 5 and Figure 6 As shown, in some embodiments of this utility model, the guide mechanism 6 further includes a second movable plate 64 and two second sliders 65. The two second sliders 65 are slidably mounted on two guide rails 62 respectively. The two second sliders 65 are connected to the second movable plate 64. The pressing execution part of the first pressing mechanism 21 is connected to the second movable plate 64. The pressing drive part of the first pressing mechanism 21 is disposed between the two guide rails 62.

[0070] Specifically, when the first clamping driver 211 drives the clamping plate 212 to move, the clamping plate 212 moves vertically along the two guide rails 62 via the second moving plate 64 and the two second sliders 65. Through the cooperation between the second sliders 65 and the guide rails 62, the clamping plate 212 can only move linearly along the guide rails 62, and the clamping plate 212 will only clamp the main body 721 of the handheld cleaning device 7 in a fixed direction without causing shaking, thereby improving the accuracy of the pull-out test results.

[0071] It should be noted that the guide mechanism 6 can also be any other structural form that meets the requirements of this utility model, and this utility model does not impose any limitations. For example, the guide mechanism 6 includes a guide rod, the two ends of which are respectively connected to the support mechanism 1. Two linear bearings are sleeved on the guide rod, one linear bearing is connected to the fixing part of the clamping driver 51, and the other linear bearing is connected to the pressure plate 212.

[0072] Furthermore, those skilled in the art will understand that the pulling mechanism 3, clamping mechanism 5, and positioning mechanism 2 (e.g., the first clamping mechanism 21, the second clamping mechanism 22, and the third clamping mechanism 23) can all have built-in control programs to enable these mechanisms to perform corresponding actions according to a predetermined test procedure. Of course, the pulling test device may also include a controller commonly used in the art, with the pulling mechanism 3, clamping mechanism 5, and positioning mechanism 2 respectively connected to the controller via signals. The controller can control the pulling mechanism 3, clamping mechanism 5, and positioning mechanism 2 to perform corresponding actions according to the test procedure.

[0073] Below, taking a floor scrubber as an example, combined with... Figures 2 to 4 The process of using the pull-out testing device is explained.

[0074] First, the floor scrubber is placed in the pull-out test apparatus, with the cleaning execution part 722 of the floor scrubber placed in the receiving groove 234 of the support base 231, and the main body part 721 of the floor scrubber placed in the positioning groove 224 of the positioning base 223. Then, the third clamping driver 232 drives the second clamping arm 233 to clamp and fix the cleaning execution part 722, the second clamping driver 221 drives the first clamping arm 222 to clamp and fix the outer periphery of the main body part 721, and the first clamping driver 211 drives the clamping plate 212 to clamp the top of the main body part 721. Then, the clamping driver 51 drives the two clamping arms 52 to clamp and fix the gripping mechanism 71; then, the pull-out driver 31 drives the clamping driver 51 to move upward, pulling the gripping mechanism 71. During the pull-out test, the tension and pressure sensor 4 sends pull-out force data to the data processing device. After the test is completed, the pull driver 31 drives the clamping driver 51 to move downward, the clamping driver 51 drives the two clamping arms 52 to release the gripping mechanism 71, the first pressing driver 211 drives the pressing plate 212 to move upward, the second pressing driver 221 drives the first pressing arm 222 away from the main body 721, and the third pressing driver 232 drives the second pressing arm 233 away from the cleaning execution part 722.
