Description

Technical Field

[0001] The invention relates to the technical field of a cooker handle fatigue testing machine, in particular to a cooker handle fatigue testing machine which can be adapted to different handle models. Background Art

[0002] The fatigue resistance of a cookware handle is one of the important indicators for measuring its quality. The test is to see whether the handle will become loose, deformed, or have other functional problems after a certain number of cycles of use. This test helps to discover potential defects in the handle design and ensure that the cookware can maintain good performance during use and avoid safety hazards caused by handle problems. The fatigue resistance test of the cookware handle is mainly carried out using a fatigue tester. During use, the handle will be fixed to the testing machine, and then a counterweight steel ball will be added to the inside of the cookware. The testing machine will drive the cookware to reciprocate a specified number of times, and then observe whether the handle is loose, thereby realizing automatic detection of the fatigue resistance of the cookware handle.

[0003] However, the traditional fatigue testing machine needs to fix the handle during use. During the fixing process, one hand is required to hold up the pot, and the other hand is required to twist multiple fixing knobs to fix the handle. Since the pot itself has a certain weight and is equipped with counterweight steel balls inside, it is more physically demanding to hold it up, and when the physical strength is insufficient, the pot may also tip over, causing the counterweight steel balls to roll out from the inside of the pot, resulting in poor convenience and safety of use. In addition, before the test, the angle of the bottom of the pot needs to be adjusted to a horizontal state, so the support base on the testing machine needs to be rotated, and the pot will rotate with the support base. After the angle adjustment is completed, the support base needs to be fixed to prevent it from rotating during the test. Generally, the support base is fixed by pressing the end of the knob against the support base and then fixing it by friction. Since the pot and the counterweight will apply a large torque to the support base, the support base and the knob are easy to loosen during the test, resulting in a change in the angle, which will affect the results of the experiment and lead to poor test stability. In addition, the screw rod used to adjust the support plate on the test machine will be exposed to the air for a long time during use, so its surface is prone to dust accumulation. When there is too much dust, it will cause jamming during the adjustment process, which is inconvenient to use. Summary of the invention

[0032] like Figure 1 , Figure 2 and Figure 3As shown, the counterweight structure 8 includes a connecting block 801 and a connecting block 802, the supporting seat 4 is fixedly connected with the connecting block 801, one end of the connecting block 801 is rotatably connected with the connecting block 802, one end of the connecting block 802 is fixedly connected with a connecting rope 803, the moving rod 2 is fixedly connected with two connecting seats 804, one end of the connecting seat 804 is rotatably connected with a guide wheel 805, the two guide wheels 805 are wrapped with the same connecting rope 803, one end of the connecting rope 803 is fixedly connected with a connecting frame 806, one side of the connecting frame 806 is fixedly connected with a sliding seat 808, the sliding seat 808 is slidably connected to the moving rod 2, a plurality of counterweight blocks 809 are placed inside the connecting frame 806, An opening 807 is provided at the top of one side of the connecting frame 806, two second grooves 810 are provided at both ends of the counterweight block 809, the cross-section of the support seat 4 is a U-shaped structure, the tightening structure 5 includes a first knob 501 and a friction plate 502, two first knobs 501 are threadedly connected to the two ends of the connecting shaft 3, two first grooves 503 are provided on both sides of the support seat 4, the friction plate 502 is engaged inside the first groove 503, one end of the first knob 501 is in contact with the friction plate 502, the outer side of the cross-section of the friction plate 502 is a hexagonal structure, the connecting shaft 3 runs through the friction plate 502, and the connecting shaft 3 and the friction plate 502 are slidably connected, that is, when the cookware is fixed, it can be turned by turning the first knob 501, when one end of the two first knobs 501 does not conflict with the friction plate 502, the support base 4 can be rotated, and the cookware will rotate with the support base 4. During the rotation of the support base 4, the connecting block 801 will be driven to move, and the movement of the connecting block 801 will drive the connecting block 802 to move, and the connecting block 802 will drive the connecting frame 806 to move through the connecting rope 803. During the movement of the connecting frame 806, the sliding seat 808 will slide on the moving rod 2, so as to guide the movement of the connecting frame 806. Since a plurality of counterweight blocks 809 are placed inside the connecting frame 806, the gravity of a part of the cookware and the counterweight steel balls inside the cookware can be balanced, so that it is more labor-saving in the process of adjusting the angle, and at the same time, when the angle adjustment is completed After the end of the first knob 501 is pressed against the friction plate 502, the support seat 4 can be prevented from rotating due to a large torque, thereby effectively improving the stability of use. The opening 807 can be provided to facilitate the placement and removal of the counterweight 809, so that the weight of the counterweight can be adjusted according to actual conditions, thereby effectively improving the flexibility of use. The two second grooves 810 are provided at both ends of the counterweight 809 to facilitate the grabbing of the counterweight 809. The two guide wheels 805 can guide the connecting rope 803. When the bottom end of the cookware is adjusted to a horizontal state, the support seat 4 is stopped from rotating, and then the first knob 501 is rotated in the opposite direction to make its end press against the friction plate 502, thereby achieving the fixation of the support seat 4 after the angle is adjusted.As the friction plate 502 is used for a longer time, its surface may become smooth. Therefore, in order to fix the support seat 4 more stably, the friction plate 502 needs to be replaced. When replacing, first twist off the first knob 501 from the end of the connecting shaft 3. After the first knob 501 is twisted off, it will not resist the friction plate 502. Then, the old friction plate 502 can be taken out from the inside of the first groove 503, and the new friction plate 502 can be put into the inside of the first groove 503, thereby realizing the replacement of the friction plate 502, effectively ensuring the fixing effect of the support seat 4, and making it more convenient to use.

[0033] Specifically, Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7As shown, the fixing structure 6 includes a connecting plate 601 and a fixing module 602. The top of the support seat 4 is provided with a connecting plate 601. The bottom end of the connecting plate 601 is fixedly connected to two plug-in blocks 607. The plug-in blocks 607 penetrate the support seat 4. The plug-in blocks 607 are provided with a slot 608. The top of the connecting plate 601 is detachably connected to the fixing module 602 through a plurality of bolts. Four screw rods 603 are threadedly connected to the connecting plate 601. One end of the screw rod 603 is fixedly connected to a second knob 604. A pressing plate 605 is penetrated by two adjacent screw rods 603. The pressing plate 605 is slidably connected to the screw rod 603. A rubber strip 606 is fixedly connected to the pressing plate 605. One end of the plug-in block 607 The cross section of the second knob 604 is a trapezoidal structure, the diameter of the cross section of the second knob 604 is larger than the diameter of the cross section of the screw rod 603, the limiting structure 7 includes a first guide seat 701 and a pull plate 702, the support seat 4 is fixedly connected with the first guide seat 701, the first guide seat 701 is slidably connected with the pull plate 702, the pull plate 702 is provided with two guide grooves 703, the support seat 4 is fixedly connected with two second guide seats 706, the second guide seat 706 is slidably connected with a clamping block 705, one end of the clamping block 705 is clamped with the adjacent clamping groove 608, the clamping block 705 is fixedly connected with a guide shaft 704, one end of the guide shaft 704 extends to the inside of the guide groove 703 and is slidably connected with the pull plate 702 , a V-shaped structure is formed between the two guide grooves 703, a reset spring 707 is fixedly connected between the two clamping blocks 705, the cross section of one end of the pull plate 702 is an L-shaped structure, and the cross section of one end of the clamping block 705 is a trapezoidal structure, that is, when the cookware handle needs to be fixed, the pull plate 702 can be pulled, and the movement of the pull plate 702 drives the two guide grooves 703 to move, and when the guide groove 703 moves, the guide shaft 704 will move inside the guide groove 703, and when the guide shaft 704 moves inside the guide groove 703, the clamping block 705 will move away from the clamping groove 608, and the reset spring 707 will contract. When the ends of the two clamping blocks 705 are separated from the clamping groove 608, the pull plate 702 can be stopped, and then the connecting plate 608 can be moved. 01 and remove it from the support base 4. After the connecting plate 601 is removed, it can be moved to the pot handle and the pot handle can be located inside the fixing module 602. Since the fixing module 602 and the connecting plate 601 are detachably connected by a plurality of bolts, when it is necessary to fix different types of pot handles, it is only necessary to replace the fixing modules 602 of different types, thereby effectively improving the flexibility of use. When the pot handle is located inside the fixing module 602, it can be rotated by turning the second knob 604 in sequence. The rotation of the second knob 604 will drive the screw rod 603 to rotate. Since the screw rod 603 and the connecting plate 601 are threadedly connected, the second knob 604 will be driven to move in its axial direction during the rotation of the screw 603.The second knob 604 moves, which drives the pressing plate 605 to move toward the cookware handle. The second knob 604 is rotated in sequence until the two rubber strips 606 are pressed against the cookware handle, thereby fixing the cookware handle to the connecting plate 601. Since the rubber strip 606 has a certain elasticity, the contact area between the rubber strip 606 and the cookware handle can be increased during the fixing process, thereby fixing the cookware handle more firmly. When the cookware handle and the connecting plate 601 are fixed, the connecting plate 601 can be moved to make the two rubber strips 606 and the cookware handle tightly pressed against each other. The plug block 607 is inserted into the support seat 4. Since the cross section of one end of the block 705 is a trapezoidal structure, the plug block 607 will resist the movement of the block 705 during the movement. When the connection plate 601 and the support seat 4 are in conflict, the block 705 will be engaged with the slot 608 under the action of the return spring 707. At this time, the connection plate 601 and the support seat 4 cannot be separated, thereby achieving the fixation of the pot. Since the pot does not need to be lifted for a long time during the fixation process, it can save physical strength and improve the convenience of operation.

[0034] Specifically, Figure 1 , Figure 2 and Figure 8 As shown, the protective structure 9 includes a first protective cover 901 and a second protective cover 902. The first protective cover 901 is detachably connected to the test machine body 1 through a plurality of bolts, and the second protective cover 902 is detachably connected to the support plate 13 through a plurality of bolts. The first protective cover 901 and the second protective cover 902 are slidably connected, that is, after the bottom end of the cookware is adjusted to be level with the rubber pad 14, the hand wheel 10 can be turned, and the rotation of the hand wheel 10 will cause the screw rod 11 to rotate, and the rotation of the screw rod 11 will drive the support plate 13 and the rubber pad 14 to rotate. When the rubber pad 14 contacts the bottom end of the cookware, the hand wheel 10 is stopped, and the position of the rubber pad 14 is adjusted. The four guide columns 12 are on the support plate. The plate 13 plays a role of motion guide during movement. When the position adjustment of the rubber pad 14 is completed, the test can be carried out by starting the test machine body 1. During the test, the moving rod 2 will move back and forth, thereby causing the cookware to move back and forth. By observing whether the handle is loose after the cookware reciprocates a set number of times, the fatigue resistance of the cookware handle can be tested. During the movement of the support plate 13, the second protective cover 902 will slide on the first protective cover 901. The first protective cover 901 and the second protective cover 902 can shield and protect the screw rod 11, thereby ensuring the cleanliness of the surface of the screw rod 11 and avoiding the jamming during transmission caused by dust gathering on the surface of the screw rod 11, making it more convenient to use.

[0035] When the present invention is in use, when it is necessary to fix the cookware handle, the pull plate 702 can be pulled, and the movement of the pull plate 702 drives the two guide slots 703 to move. When the guide slots 703 move, the guide shaft 704 moves inside the guide slots 703. When the guide shaft 704 moves inside the guide slots 703, the block 705 moves away from the slot 608, and the reset spring 707 contracts. When the ends of the two blocks 705 are separated from the slot 608, the pull plate 702 can be stopped, and then the connecting plate 601 can be moved and removed from the support seat 4, and the connecting plate 601 can be removed from the support seat 4. After being removed, it can be moved to the pot handle, and the pot handle is located inside the fixing module 602. Since the fixing module 602 and the connecting plate 601 are detachably connected by multiple bolts, when it is necessary to fix different types of pot handles, it is only necessary to replace the fixing modules 602 of different types, thereby effectively improving the flexibility of use. When the pot handle is located inside the fixing module 602, the second knob 604 can be turned in sequence, and the rotation of the second knob 604 will drive the screw rod 603 to rotate. Since the screw rod 603 and the connecting plate 601 are threadedly connected, the screw rod 603 can be rotated. The second knob 604 is connected to the cooker handle 601, so when the screw rod 603 rotates, the second knob 604 is driven to move in its axial direction. When the second knob 604 moves, the pressing plate 605 is driven to move toward the cooker handle. The second knob 604 is rotated in sequence until the two rubber strips 606 are tightly pressed against the cooker handle, thereby fixing the cooker handle to the connecting plate 601. Since the rubber strip 606 has a certain elasticity, the contact area between the rubber strip 606 and the cooker handle can be increased during the fixing process, so that the cooker handle can be fixed more stably. When the cooker handle is fixed to the connecting plate 601, After completion, the connecting plate 601 can be moved, and the two plug blocks 607 can be inserted into the support seat 4. Since the cross section of one end of the clamping block 705 is a trapezoidal structure, the plugging block 607 will resist the movement of the clamping block 705 during the movement. When the connecting plate 601 and the support seat 4 are in conflict, the clamping block 705 will be engaged with the clamping groove 608 under the action of the return spring 707. At this time, the connecting plate 601 and the support seat 4 cannot be separated, thereby achieving the fixation of the cookware. Since the cookware does not need to be lifted for a long time during the fixing process, physical strength can be saved and the convenience of operation is improved.

[0036] When the cookware is fixed, the first knob 501 can be turned. When one end of the two first knobs 501 does not conflict with the friction plate 502, the support base 4 can be turned. The cookware will rotate with the support base 4. During the rotation of the support base 4, the connecting block 801 will be driven to move. The movement of the connecting block 801 will drive the connecting block 802 to move. The connecting block 802 will drive the connecting frame 806 to move through the connecting rope 803. During the movement of the connecting frame 806, the sliding seat 808 will slide on the moving rod 2, so that the connecting frame 806 can be adjusted. 6 plays a role of motion guide. Since a plurality of counterweights 809 are placed inside the connection frame 806, the gravity of a part of the pot and the counterweight steel balls inside the pot can be balanced, so that it is not only more labor-saving in the process of adjusting the angle, but also after the angle adjustment is completed, when the end of the first knob 501 is pressed against the friction plate 502, it can also prevent the support seat 4 from being rotated by a large torque, thereby effectively improving the stability of use. The opening 807 can be provided to facilitate the removal and placement of the counterweight 809, so that the weight of the counterweight can be adjusted according to actual conditions, thereby effectively improving the flexibility of use. The two second grooves 810 are provided at both ends of the counterweight 809 to facilitate the grabbing of the counterweight 809. The two guide wheels 805 can guide the connection rope 803. When the bottom end of the pot is adjusted to a horizontal state, the support seat 4 is stopped from rotating, and then the first knob 501 is rotated in the opposite direction to make the end of the first knob 501 press against the friction plate 502, so as to achieve the fixation of the support seat 4 after the angle is adjusted. As the friction plate 502 is used for a longer time, its surface may become The friction plate 502 is smooth, so in order to fix the support seat 4 more stably, the friction plate 502 needs to be replaced. When replacing, the first knob 501 is first twisted off from the end of the connecting shaft 3. After the first knob 501 is twisted off, the friction plate 502 will not be resisted. Then, the old friction plate 502 can be taken out from the inside of the first groove 503, and the new friction plate 502 can be put into the inside of the first groove 503, thereby realizing the replacement of the friction plate 502, effectively ensuring the fixing effect of the support seat 4, and making it more convenient to use;

[0037] After the bottom end of the cookware is adjusted to be level with the rubber pad 14, the hand wheel 10 can be turned. The rotation of the hand wheel 10 will cause the screw rod 11 to rotate, and the rotation of the screw rod 11 will drive the support plate 13 and the rubber pad 14 to rotate. When the rubber pad 14 contacts the bottom end of the cookware, the hand wheel 10 is stopped. At this time, the position of the rubber pad 14 is adjusted. The four guide columns 12 play a role of motion guidance during the movement of the support plate 13. When the position of the rubber pad 14 is adjusted, the test can be carried out by starting the test machine body 1. During the test, the test machine body 1 is moved. The rod 2 will move back and forth, thereby causing the cookware to move back and forth. By observing whether the handle is loose after the cookware has moved back and forth a set number of times, the fatigue resistance of the cookware handle can be tested. During the movement of the support plate 13, the second protective cover 902 will slide on the first protective cover 901.
