Description

Technical Field

[0001] This utility model relates to the field of testing device technology, and more specifically, to a damping life testing machine. Background Technology

[0002] A damper is a device that provides resistance to motion and dissipates kinetic energy. Existing toilet seats or toilet seat rings are connected to the toilet bowl via dampers. When the toilet seat or ring needs to descend from an open to a closed position, the damping force of the damper controls the descent, allowing the toilet seat and / or ring to descend slowly, reducing impact between the toilet seat and / or ring and the toilet bowl, thus preventing damage. After a period of use, the damping force of the toilet damper decreases, causing the toilet seat and ring to descend too quickly and break. Therefore, it is necessary to test the lifespan of the manufactured damping components. Currently, existing damper slow-descent tests often involve manually pushing the toilet seat to fold and descend, which is labor-intensive and costly. Therefore, a damping lifespan testing machine is proposed. Utility Model Content

[0004] To address at least one of the aforementioned problems, this invention first provides a damping life testing machine that uses a cylinder and a pusher to move the device to be tested to the testing position. This eliminates the need for manual intervention and detects the damping life by counting, thereby improving the testing accuracy.

[0005] (II) Technical Solution

[0006] To solve the aforementioned technical problem, this utility model provides a damping life testing machine, including a testing frame, a first mounting frame, and a second mounting frame. The first mounting frame and the second mounting frame are arranged and installed on the table of the testing frame. The first mounting frame includes a first connecting metal frame, on which a first damping element is provided. The first damping element is hingedly connected to a test toilet seat. A first support assembly is provided on one end panel of the test toilet seat. The second mounting frame includes a second connecting metal frame, on which a second damping element is provided. The second damping element is hingedly connected to a test toilet seat. A second support assembly is provided on one end panel of the test toilet seat. The testing frame has a vertical support on the side away from the first support assembly. A first reset frame and a second reset frame are provided on the vertical support. When the first support assembly pushes the test toilet seat to rotate around the first damping element to a designated position, the first reset frame pushes the test toilet seat to flip downwards. When the second support assembly pushes the test toilet seat to rotate around the second damping element to a designated position, the second reset frame pushes the test toilet seat to flip downwards.

[0007] Furthermore, the first reset frame includes a first abutting end, and the first abutting end is provided with a first reset cylinder within the vertical support; the second reset frame includes a second abutting end, and the second abutting end is provided with a second reset cylinder within the vertical support.

[0008] Furthermore, the first damping component includes two sets of hinge pins, each hinge pin having multiple sets of fixed connection holes, each fixed connection hole containing a fixing pin, which is connected to the first connecting metal frame. Each hinge pin has a set of hinge holes on its outer side, each hinge hole containing a set of connecting shafts, the outer ends of which are fixedly connected to the test toilet seat.

[0009] Furthermore, the second mounting bracket has the same mounting structure and components as the first mounting bracket.

[0010] Furthermore, the first support assembly includes two sets of rubber columns, with an arc-shaped top rod hinged between the two sets of rubber columns.

[0011] Furthermore, the other end of the arc-shaped top rod is fixedly connected to the push frame, and a cross universal coupling is provided at the bottom of the middle section of the push frame. The cross universal coupling is hinged to the extension rod of the lifting cylinder.

[0016] (III) Beneficial Effects

[0017] This utility model provides a damping life testing machine, which is equipped with a testing and pushing device, such as two sets of support components, to push the test toilet seat and test toilet ring to the test position respectively. Then, two sets of reset frames apply pushing force to the test toilet seat and test toilet ring respectively to test the time of fall of the toilet seat and test toilet ring and the number of falls before the damping fails. This is used as the basis for judging the damping life. This solution does not require manual intervention and can use mechanical components to quickly repeat the test operation. The damping life is judged by the fall time node and the number of falls. Its test results are relatively accurate and have higher reliability than manual test. Attached Figure Description

Detailed Implementation

[0026] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] See Figures 1 to 6 This utility model provides a damping life testing machine, including a testing frame 1, a first mounting frame 2, and a second mounting frame 3. The first mounting frame 2 and the second mounting frame 3 are arranged and installed on the table of the testing frame 1. The first mounting frame 2 includes a first connecting metal frame 21, on which a first damping element is provided. The first damping element is hinged to a test toilet seat 9. A first support assembly 7 is provided on one end panel of the test toilet seat 9. The second mounting frame 3 includes a second connecting metal frame, on which a second damping element is provided. The second damping element is hinged to a test toilet seat 10. A second support assembly 8 is provided on one end panel of the test toilet seat 10. The testing frame 1 has a vertical support 4 on the side away from the first support assembly 7. The vertical support 4 has a first reset frame 5 and a second reset frame 6. When the first support assembly 7 pushes the test toilet seat 9 around the first... When the damping element rotates to the designated position, the first reset frame 5 pushes the test toilet seat 9 to flip downwards. When the second support assembly 8 pushes the test toilet seat 10 to rotate around the second damping element to the designated position, the second reset frame 6 pushes the test toilet seat 10 to flip downwards. The first support assembly 7, controlled by a signal, pushes the test toilet seat 9 upwards to simulate the state of the toilet seat being open, so that the first reset frame 5 can push the test toilet seat 9 to flip, thus simulating the effect of the gravity of the closed test toilet seat 9 on the first damping element in the first mounting frame 2. The second support assembly 8, controlled by a signal, pushes the test toilet seat 10 upwards to simulate the state of the open test toilet seat, so that the second reset frame 6 can push the test toilet seat 10 to flip, thus simulating the effect of the gravity of the closed test toilet seat 10 on the second damping element in the second mounting frame 3. The effects of the flipping of the toilet seat and toilet seat on the service life of the damping element are set separately in sequence.

[0028] In this scheme, the first support assembly 7 and the second support assembly 8 can be simultaneously controlled by a signal to raise the test toilet seat 9 and the test toilet seat 10, and the first reset frame 5 and the second reset frame 6 can simultaneously push the test toilet seat 9 and the test toilet seat 10 to reset; they can also control the output of the two sets of support assemblies and the output of the two sets of reset frames respectively, so that the test toilet seat 9 and the test toilet seat 10 slowly descend under their respective damping effects to test the damping effect and independently test the service life of the two sets of damping components.

[0029] Reference Figure 1 and Figure 3The first reset frame 5 includes a first abutting end, and the first abutting end is provided with a first reset cylinder in the vertical support 4. The second reset frame 6 includes a second abutting end, and the second abutting end is provided with a second reset cylinder in the vertical support 4. Both the first reset cylinder and the second reset cylinder are hidden in the vertical support 4, and the output ends of both sets of reset cylinders are inclined upwards towards the test toilet seat 9 and the test toilet ring 10. When a simulated pushing operation is required, the abutting end corresponding to the operation of the target reset cylinder extends out and outputs a pushing force to the test toilet seat 9 or the test toilet ring 10, pushing the test toilet seat 9 or the test toilet ring 10 to flip downwards.

[0030] Reference Figure 6 The first damping component includes two sets of hinge pins 22. Each hinge pin 22 has multiple sets of fixed connection holes 25. Each fixed connection hole 25 contains a fixed pin 26, which is connected to the first connecting metal frame 21. Each hinge pin 22 has a set of hinge holes 23 on its outer side. Each hinge hole 23 contains a set of connecting shafts 24. The outer ends of the connecting shafts 24 are fixedly connected to the test toilet seat 9. Each of the two sets of hinge pins 22 is connected to the first connecting metal frame 21 through a fixed pin 26. The two sets of hinge pins 22 are respectively arranged on the first connecting metal frame 21 and spaced apart to adapt to the hinge of the test toilet seat 9. The outer ends of each set of hinge pins 22 that are hinged to the test toilet seat 9 are respectively hinged to the connecting shafts 24 through the hinge holes 23. That is, when the test toilet seat 9 rotates, it drives the shaft of the connecting shaft 24 located in the hinge holes 23 to rotate within the hinge holes 23 to test the damping force of this hinge structure.

[0031] The second mounting bracket 3 has the same mounting structure and components as the first mounting bracket 2. That is, the connection method and structure between the test toilet seat 10 and the second mounting bracket 3 are the same as those of the first mounting bracket 2. Their rotation mode and test principle are also the same, so they will not be described again here.

[0032] See Figures 3 to 5 The first support assembly 7 includes two sets of rubber columns 71, with an arc-shaped top rod 72 hinged between the two sets of rubber columns. The two sets of rubber columns 71 are located at the center of the contact end of the test toilet seat 9, which facilitates quick positioning of the pushing force point and accurate pushing of the test toilet seat 9 to flip upward. During the up-and-down rotation of the test toilet seat 9, the arc-shaped top rod 72 is supported by its arc-shaped structure and is pushed by the thrust to rotate the test toilet seat 9. While ensuring accurate output of the pushing operation, it will not come into contact with the testing frame 1, thus avoiding interference with the test results or damage to the testing frame 1.

[0033] The rubber structure of the rubber column 71 has a good cushioning effect. The rubber column 71 is not connected to the test toilet seat 9, but only abuts against the test toilet seat 9 during the pushing process. That is, after the test toilet seat 9 is pushed to the test position, the arc-shaped top rod 72 drives the rubber column 71 to quickly return to the table of the test frame 1, without obstructing the pushing test of the test toilet seat 9. When the test toilet seat 9 returns to the table of the test frame 1, it can provide cushioning protection for it, and abut against the test toilet seat 9 again, so that the next damping test process can be started immediately.

[0034] The other end of the arc-shaped top rod 72 is fixedly connected to the push frame 73. The bottom of the middle section of the push frame 73 is provided with a cross universal coupling 74. The cross universal coupling 74 is hinged to the extension rod of the lifting cylinder 75. The push frame 73 is rotated with the upper rotating pin 12 as the rotation center. The lifting cylinder 75 controls the extension shaft to extend, which causes the cross universal coupling 74 to move upward. The connection end between the push frame 73 and the arc-shaped top rod 72 rotates upward, pushing the test toilet seat 9 to the set position. When the test toilet seat 9 is in the test state, the lifting cylinder 75 drives the push frame 73 to return to its original position, pulling the rubber column 71 back to the table of the test frame 1, thus establishing a lowering test environment for the test toilet seat 9. The above operation can then be repeated.

[0035] The inner cavity of the testing frame 1 is equipped with two sets of upper support groups 11. Each set of upper support groups 11 is equipped with a set of upper rotating pins 12. One set of upper rotating pins 12 is hinged to the end of the push frame 73 away from the arc-shaped top rod 72. The push frame 73 is centered on this set of upper rotating pins 12. The lifting cylinder 75 controls the extension shaft to extend, pulling the cross universal coupling 74 to move upward. The connection end of the push frame 73 and the arc-shaped top rod 72 rotates upward, pushing the test toilet seat 9 to the set position. When the test toilet seat 9 is in the test state, the lifting cylinder 75 drives the push frame 73 to return to the original position, pulling the rubber column 71 back to the table of the testing frame 1, thus establishing a lowering test environment for the test toilet seat 9. The above operation can then be repeated.

[0036] Another set of upper rotating pins 12 are hinged to the push assembly where the second bracket assembly 8 is located, pushing the second bracket assembly 8 to rotate around the set of upper rotating pins 12.

[0037] The connection method between the second bracket assembly 8 and the test toilet seat 10 is slightly different from the connection method of the first bracket assembly 7. (Refer to...) Figure 1 and Figure 2 The two sets of rubber posts that abut against the test toilet seat 10 in the second bracket assembly 8 are longer than the two sets of rubber posts 71 on the first bracket assembly 7. They are used to extend to establish contact with the test toilet seat 10. The remaining structure connected to these two sets of rubber posts is exactly the same as that on the first bracket assembly 7, which simplifies the assembly and maintenance. Its rotation mode and testing principle are also the same, so they will not be described in detail here.

[0038] The inner cavity of the testing frame 1 is provided with two sets of lower supports 13, and each lower support 13 is provided with a lower rotating pin 14. One set of lower rotating pins 14 is hinged to the bottom end of the lifting cylinder 75. The other end of the lower support 13 is provided with a connector 15, which is fixedly connected to the testing frame 1. The two sets of lower supports 13, together with the connector 15, establish the installation of the two sets of lower rotating pins 14, so that the two sets of lower rotating pins 14 can respectively establish a connection with the lifting cylinder 75 and the other set of the second support assembly 8. The lifting cylinder 75 is connected and its extension can change the support state of the push frame 73 through the universal joint 74. The angle of the push frame 73 changes, and the setting angle of the lifting cylinder 75 is changed in conjunction with the universal joint 74. The lifting cylinder 75 rotates on the lower rotating pin 14 connected to it, changing the setting state of the push frame 73. The connection and transmission method of the other set of lifting cylinders in the second bracket assembly 8 are the same as those of the lifting cylinder 75, and will not be described in detail here.

[0039] See Figure 2 A display panel 41 is provided on the vertical support 4. Multiple sets of indicator lights 42 are provided below the display panel 41. The display panel 41 and each set of indicator lights 42 are electrically connected to the control terminal. The control terminal is connected to the counter to calculate the number of pushes of the toilet seat 9 and the toilet ring 10 before their respective dampers fail, so as to determine the life of the dampers. The display panel 41 can display data such as the number of tests, the frequency of lifting and resetting pushes, and the arrival time node. A power switch and a power indicator light are provided between the indicator lights 42 and the display panel 41 to start the testing machine and check the power status. The indicator lights 42 include a button test light, a button alarm light, a seat ring test light, a seat ring alarm light, a toilet seat test light, and a toilet seat alarm light to help determine the working status of each set of testing devices.

[0040] On the test frame 1, below the display panel 41, there is a third connecting metal frame 45. One end of the third connecting metal frame 45 is equipped with a push cylinder 43, and the other end of the third connecting metal frame 45 is equipped with a signal button 44. The third connecting metal frame 45 fixes the connection between the push cylinder 43 and the signal button 44. The push cylinder 43 extends according to the working frequency of the first support assembly 7 and / or the second support assembly 8. Pressing the signal button 44 controls the extension of the first reset cylinder or the second reset cylinder, controlling the working frequency of the first reset frame 5 and / or the second reset frame 6, so as to control the pushing frequency of the two sets of test ends.

[0041] When the first support assembly 7 and the second support assembly 8 arrive at their positions at the same frequency, the control signal button 44 for the extension of the push cylinder 43 is pressed for 0.2 seconds, simultaneously controlling the extension of both sets of reset frames. When only the first support assembly 7 reaches the test position, the control signal button 44 for the extension of the push cylinder 43 is pressed for 0.4 seconds, controlling only the extension of the first reset frame 5. When only the second support assembly 8 reaches the test position, the control signal button 44 for the extension of the push cylinder 43 is pressed for 0.6 seconds, controlling only the extension of the second reset frame 6.

[0042] The present invention provides a damping life testing machine, in which a test toilet seat 9 is supported and pushed to the test position by a first support assembly 7. The first support assembly 7 is retracted into the test frame 1 under the control of a lifting cylinder 75, so that the first reset frame 5 can push the test toilet seat 9 down to simulate the closing of the toilet seat, in order to test the damping effect and life of the first damping component; and a test toilet seat 10 is supported and pushed to the test position by a second support assembly 8. The second support assembly 8 is retracted into the test frame 1 under the control of a lifting cylinder, so that the second reset frame 6 can push the test toilet seat 10 down to simulate the closing of the toilet seat, in order to test the damping effect and life of the second damping component.

[0043] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
