[0034] The technical solution of this application and how the technical solution of this application solves the above-mentioned technical problems are described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0035] Please see Figures 1 to 4 The inverter handle testing device provided in this application includes a frame 100, a fixing component 200, and a testing component 300.

[0036] The fixing assembly 200 includes a fixing platform 210 and a clamping member 220. The fixing platform 210 is disposed on the frame 100, and the clamping member 220 is disposed on the fixing platform 210. The clamping member 220 is used to clamp the inverter 10.

[0037] The test assembly 300 includes a loading platform 310, a loading element 320, a cable 330, and a measuring element 340. The loading platform 310 is movably mounted on the frame 100. One end of the cable 330 is connected to the loading platform 310, and the other end is used to connect to the handle of the inverter 10. The loading element 320 is mounted on the frame 100, and its output is connected to the loading platform 310. The loading element 320 can drive the loading platform 310 away from the fixed platform 210 so that the cable 330 pulls the handle of the inverter 10. The measuring element 340 is used to test the tension of the cable 330.

[0038] The fixing assembly 200 is used to fix the inverter 10 to be tested. The frame 100, as the supporting structure of the entire testing device, can be made of lightweight, high-strength materials such as high-strength steel or aluminum alloy, giving it sufficient rigidity and stability to withstand various loads during the test. The fixing platform 210 is used to place the inverter 10, and it is equipped with clamping members 220 for holding and fixing the inverter 10. The clamping members 220 can limit the position of the inverter 10, keeping it in a fixed state to ensure the tensile test can be performed normally.

[0039] Test assembly 300 is used to perform tensile testing on the structural load-bearing performance of the inverter 10 handle. Loading platform 310, as a fixed structure for cable 330, transmits the load force to the handle via cable 330. It should be noted that loading platform 310 can move relative to fixed platform 210 along frame 100 to simulate the stress on inverter 10 handle during actual use. Loading element 320 provides the required load force for the test, driving loading platform 310 to move and thus pull the inverter 10 handle. Loading element 320 is typically driven by electric, pneumatic, or hydraulic methods. The output of loading element 320 is connected to loading platform 310, and the tensile force is applied by driving loading platform 310 to move.

[0040] As a medium for transmitting tensile force, cable 330 transfers the tensile force provided by loading element 320 to the inverter 10 handle. It is understood that cable 330 needs to possess sufficient strength and stability to ensure that it does not break or fail during testing. For example, cable 330 is made of high-strength steel wire rope or synthetic fibers, possessing sufficient strength and abrasion resistance. To reduce deformation of cable 330 during the transmission of loading force, cable 330 is a steel cable chain, which has higher structural strength than traditional steel wire rope.

[0041] The measuring element 340 is used to measure the tension of the cable 330, i.e., the tension borne by the handle of the inverter 10. The measuring element 340 can be a force sensor or a dynamometer, which can monitor and record the tension in real time. The measuring element 340 is connected to the loading element 320 or the cable 330 to accurately measure and record the tension data during the test.

[0042] During actual testing, the inverter 10 is first placed on the fixed platform 210 and securely clamped using the clamping device 220. Then, one end of the pull cable 330 is connected to the loading platform 310, and the other end is connected to the handle of the inverter 10. All connections are ensured to be secure and reliable to prevent detachment or damage during testing. Next, the loading device 320 is activated, driving the loading platform 310 to move. As the loading platform 310 moves, the handle of the inverter 10 is pulled via the pull cable 330, simulating the stress conditions in actual use. Simultaneously, the measuring device 340 monitors and records the magnitude of the pulling force in real time to evaluate the load-bearing capacity of the inverter 10's handle.

[0043] The inverter handle testing device of this application embodiment includes a fixing component 200 and a measuring component. The fixing component 200 fixes the inverter 10 to be measured through a fixing platform 210 and a clamping member 220. The measuring component applies the required load force for the test through a loading member 320, and transmits it to the handle of the inverter 10 through the loading platform 310 and a cable 330, thereby performing a tensile test on the handle of the inverter 10. During the measurement process, the measuring component records the magnitude of the load force in real time through a measuring member 340 to evaluate the load-bearing performance of the inverter 10 handle. Therefore, the inverter handle testing device provided in this application embodiment facilitates the measurement and evaluation of whether the handle of the inverter 10 meets production standards.

[0044] In one optional embodiment, the clamping member 220 includes a first clamping block 221 and a second clamping block 222 disposed opposite to each other. The first clamping block 221 is fixedly disposed on the fixed platform 210, and the second clamping block 222 is movably disposed on the fixed platform 210 relative to the first clamping block 221.

[0045] The first clamping block 221 and the second clamping block 222 are positioned opposite each other, defining the placement space for the inverter 10. With the combined action of the first clamping block 221 and the second clamping block 222, the inverter 10 can be kept stable during testing, preventing it from falling off or shifting due to shaking.

[0046] The second clamping block 222 is movably mounted on the fixed platform 210 relative to the first clamping block 221. Thus, by moving the second clamping block 222, the distance between the second clamping block 222 and the first clamping block 221 can be adjusted to accommodate inverter 10 handles of different sizes.

[0047] For example, the first clamping block 221 and the second clamping block 222 are grooves or claws that match the shape of the handle of the inverter 10 so that the inverter 10 can be stably placed therein.

[0048] Therefore, by adjusting the position of the second clamping block 222, this embodiment of the application can accommodate inverter 10 handles of different sizes and shapes, thereby improving the versatility and flexibility of the testing device.

[0049] The second clamping block 222 can be adjusted manually or mechanically to change its position relative to the first clamping block 221. For example, the second clamping block 222 can be adjusted in position by a hydraulic cylinder, pneumatic cylinder, linear motor or other drive device, and apply force to the inverter 10 to clamp the inverter 10.

[0050] Please see Figure 2 In an optional embodiment, the clamping member 220 further includes a bolt fastener 223. The fixing platform 210 is provided with a strip hole 211 along the moving direction of the second clamping block 222. The second clamping block 222 is provided with a fixing hole 222a. The bolt fastener 223 is provided in the strip hole 211 and the fixing hole 222a to connect the second clamping block 222 to the fixing platform 210.

[0051] Because the fixed platform 210 has a slotted hole 211, the second clamping block 222 can move within a certain range and then be fixed in the desired position by bolt fasteners 223, making the adjustment of the clamping component 220 simple and quick. The second clamping block 222 is connected to the fixed platform 210 by bolt fasteners 223, so that the second clamping block 222 can be firmly fixed on the fixed platform 210, reducing movement and shaking caused by vibration or external force, and improving the accuracy and reliability of the test.

[0052] For example, the bolt fastener 223 may consist of a bolt, a nut, and a washer, wherein the bolt passes through the strip hole 211 on the fixing platform 210 and the fixing hole 222a on the second clamping block 222, the nut is used to fix the bolt to the other side, and the washer is used to increase the contact area and prevent loosening.

[0053] Please see Figure 3 In one optional embodiment, the cable 330 includes a connector 350, which is located at the end of the cable 330 away from the loading platform 310. The connector 350 has a connecting groove 351 extending along the length direction of the inverter 10 handle, and the connector 350 can be snapped into the handle of the inverter 10 through the connecting groove 351.

[0054] The connecting groove 351 extends along the length of the inverter 10 handle. On the one hand, it increases the connection area between the connector 350 and the handle, which helps to disperse the load force and reduce stress concentration in the handle, thus preventing deformation such as cracking and denting. On the other hand, the connecting groove 351 extending along the length of the inverter 10 handle helps to increase the snap-fit ​​space of the connector 350, thereby improving the connection stability.

[0055] Because the connector 350 has a connecting groove 351, the cable 330 can be tightly engaged with the inverter 10 handle, which helps to reduce the risk of detachment or loosening due to excessive tension or vibration during testing. At the same time, the connector 350 can be directly engaged with the inverter 10 handle, making the installation and removal of the connector 350 and the handle simple and quick, thus improving testing efficiency.

[0056] For example, the connector 350 is typically shaped to match the handle of the inverter 10, such as U-shaped, V-shaped, etc., to ensure a tight snap-fit ​​onto the handle of the inverter 10.

[0057] When different models of inverters 10 are placed on the fixed platform 210, the position of their handles may change. Therefore, the position of the cable 330 also needs to be adjusted accordingly. Optionally, multiple fixing rings are provided at intervals on the loading platform 310, and the cable 330 can be connected to each fixing ring so that the position of the cable 330 can be adjusted.

[0058] In another alternative embodiment, please refer to Figure 4 The test assembly 300 also includes a sliding seat 360, which is connected between the cable 330 and the loading table 310. The loading table 310 is provided with a groove 311, which extends along the moving direction of the second clamping block 222. The sliding seat 360 is slidably disposed in the groove 311.

[0059] The sliding seat 360 connects the cable 330 and the loading platform 310, serving as a connection and transmission component between the two. The cable 330 can be adjusted in position via the sliding seat 360 to accommodate the positions of the handles of inverters 10 of different models or sizes.

[0060] For example, the shape of the slide seat 360 matches the shape of the groove 311, such as a T-shape or an L-shape, to ensure that it can slide tightly within the groove 311. The bottom of the slide seat 360 may be provided with a roller or slider to reduce friction and wear, and improve the smoothness and durability of sliding.

[0061] In one optional embodiment, the frame 100 is provided with a guide groove along the moving direction of the loading platform 310. The loading platform 310 is slidably connected to the guide groove via pulleys, allowing the loading platform 310 to move relative to the fixed platform 210. The guide groove provides a track for the loading platform 310 to move, ensuring that the loading platform 310 maintains smooth linear motion during movement. The pulleys are rotatably mounted on the loading platform 310, and the rolling contact between the pulleys and the guide grooves helps reduce friction and wear, improving the smoothness and durability of the loading platform 310's movement.

[0062] In one optional embodiment, the frame 100 has a limiting block 370 on the side of the loading platform 310 away from the fixed platform 210. The limiting block 370 is located on the frame 100, on the side of the loading platform 310 away from the fixed platform 210. The specific position is determined based on the moving trajectory and maximum displacement of the loading platform 310, to ensure that the loading platform 310 can contact the limiting block 370 and stop moving when it reaches its maximum displacement. The limiting block 370 effectively prevents excessive displacement of the loading platform 310 during movement, avoiding test accidents caused by equipment failure or operational errors.

[0063] In an optional embodiment, a fixing platform 210 is disposed on the upper side of the loading platform 310, and the fixing platform 210 has a test port for placing the handle.

[0064] Since the inverters 10 have different sizes, the space occupied by inverters 10 of different sizes on the fixed platform 210 varies. To accommodate the distance between the loading platform 310 and the fixed platform 210, the fixed platform 210 needs to be adjusted accordingly to fit the test distance. In this embodiment, the fixed platform 210 is positioned above the loading platform 310, and the inverter 10 only occupies the space above the fixed platform 210. The test distance between the loading platform 310, located below the fixed platform 210, and the fixed platform 210 is relatively fixed. This reduces the need to adjust the position of the fixed platform 210, simplifies test preparation, and improves test efficiency. Furthermore, with the fixed platform 210 positioned above the loading platform 310, the inverter 10 exerts greater pressure on the fixed platform 210 under gravity, effectively increasing its friction and making the inverter 10 handle more stably fixed in the test position.

[0065] The test port design allows the inverter 10 handle to be easily placed into the mounting platform 210 for testing, while avoiding testing errors caused by movement or shaking of the handle during the test. Furthermore, the test port also protects the handle from damage during testing.

[0066] In one optional embodiment, the mounting platform 210 has an anti-slip layer on its surface. The anti-slip layer helps to increase the friction between the inverter 10 and the mounting platform 210, thereby reducing the possibility of the inverter 10 sliding or falling off and ensuring the testing stability of the inverter 10.

[0067] For example, the anti-slip layer can be made of materials with good elasticity and wear resistance, such as rubber, plastic, and silicone. These materials not only have good anti-slip properties but can also absorb vibrations and impacts during testing to a certain extent, protecting the handle from damage.

[0068] In one alternative embodiment, the measuring element 340 is a force sensor.

[0069] In one optional embodiment, the inverter handle testing device further includes a controller connected to the loading element 320. The controller can precisely control the moving distance, speed, and force of the loading element 320 to ensure stability and accuracy during the testing process. Using preset test parameters, the controller can automatically adjust the state of the loading element 320 to adapt to the testing requirements of handles for different models and specifications of inverters 10.

[0070] In an alternative embodiment, the frame 100 is provided with wheels 110 at the bottom to facilitate the movement of the entire device.

[0071] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the utility models disclosed herein.
