Description

Technical Field

[0001] The invention relates to the technical field of bursting strength testing devices, in particular to a bursting strength testing device for cookware. Background Art

[0002] The bursting strength tester is mainly used to test the bursting strength of materials and to evaluate the bursting strength of these materials, so as to evaluate their quality and performance. This test method can simulate various pressure conditions that the material may withstand during actual use, so as to conduct a comprehensive and objective evaluation of the bursting strength of the material. In the process of cookware production, the bursting strength tester is required to test the bursting strength of the cookware materials. During the test, the material to be tested will be placed on the test bench of the bursting strength tester, and then the bursting strength tester can be started to automatically detect the material's bursting performance.

[0003] However, during the use of traditional burst strength testers, due to the lack of protection around the test bench, the staff can easily put their hands into the test bench, so there is a risk of being crushed, resulting in poor safety in use. At the same time, when not in use, the test bench is exposed to the air for a long time, so dust is easily accumulated on its surface, which is not convenient for cleaning the surface of the test bench. The interfaces for connecting the power supply and the air pipe are also directly exposed to the air when not in use. Therefore, dust is easy to enter the interior of the burst strength tester from the air pipe interface, thereby causing adverse effects on the operation of the burst strength tester. Dust accumulation on the power socket is likely to produce a "conductivity caused by accumulated dirt", which may cause a fire, resulting in poor safety in use. During the use of the burst strength tester, silicone oil may leak. At this time, it is necessary to open the baffle at the rear to inspect the inside. Since the baffle is installed with multiple bolts, it takes a lot of time to twist the bolts with a wrench of a specific specification each time the baffle is disassembled and assembled, which is not convenient for the quick disassembly and assembly of the baffle, and is not convenient for the inspection and maintenance of the burst strength tester.

The second protective cover 302 is slidably connected with multiple locking blocks 501. The first protective cover 301 is provided with two annular grooves 503, and one end of multiple locking blocks 501 is engaged with one of the annular grooves 503. The locking block 501 is fixedly connected with the first spring 502, and the first spring 502 is fixedly connected to the second protective cover 302.

When the protective plate 602 completely blocks the power socket and the air pipe interface on the bursting strength tester body 1, the two ends of the card plate 603 will face the other two card slots 606. At this time, the second spring 605 will shrink and drive the card plate 603 to move toward the other two card slots 606 and engage with the other two card slots 606. At this time, the protective plate 602 cannot move. At this time, the power socket and the air pipe interface on the bursting strength tester body 1 are blocked and protected by the connecting frame 601 and the protective plate 602, thereby preventing dust from entering the interior of the bursting strength tester body 1 from the air pipe interface, and preventing dust from accumulating at the power socket, thereby ensuring the stable operation of the bursting strength tester body 1 while also improving its safety in use.

When the shaft 801 rotates ninety degrees, the third spring 804 will contract to make the stop block 805 engage with the groove 806 again. At this time, the shaft 801 cannot continue to rotate, and the stop plate 803 is not engaged with the bursting strength tester body 1. Then the baffle 7 can be removed from the bursting strength tester body 1, thereby realizing the rapid disassembly of the baffle 7, and then facilitating the inspection and maintenance of the bursting strength tester body 1.

[0039] When the present invention is in use, the space at the top of the test bench 2 can be shielded by the first protective cover 301 and the second protective cover 302, so that the space at the top of the test bench 2 can be reduced, which prevents the staff from putting their hands onto the test bench 2, thereby effectively improving the safety of use. When not in use, the rotating ring 402 can be rotated, and the plurality of protrusions 401 can be provided to prevent the hands from slipping when the rotating ring 402 is rotated, thereby effectively improving the stability of use. The rotation of the rotating ring 402 will drive the plurality of guide grooves 403 to move. When the guide grooves 403 move, the guide shaft 404 moves inside the guide grooves 403. When the guide shaft 404 moves inside the guide grooves 403, the block 501 will move away from one of the annular grooves 503, and the first spring 502 will extend. When one end of the plurality of blocks 501 is not engaged with one of the annular grooves 503, The second protective cover 302 can be pushed toward the test bench 2. When the bottom end of the second protective cover 302 contacts the bursting strength tester body 1, the multiple clamping blocks 501 will be engaged with another annular groove 503 under the action of the first spring 502.

Since the first protective cover 301 and the second protective cover 302 completely block the test bench 2 at this time, dust can be prevented from falling on the test bench 2, effectively ensuring the cleanliness of the surface of the test bench 2. The sealing gasket 303 can improve the sealing between the second protective cover 302 and the bursting strength tester body 1, and the first protective cover 301 and the second protective cover 302 can be removed from the bursting strength tester body 1 by twisting off the multiple nuts 305 from the multiple positioning blocks 304, thereby avoiding blocking the bursting strength tester body 1 and facilitating the inspection and maintenance of the bursting strength tester body 1.

[0040] When the bursting strength tester body 1 is not needed, the card plate 603 can be pulled, and the card plate 603 slides on the connecting column 604, and the second spring 605 stretches. When the two ends of the card plate 603 are not engaged with two of the card slots 606, the protective plate 602 can be pushed. When the protective plate 602 completely blocks the power socket and the air pipe interface on the bursting strength tester body 1, the two ends of the card plate 603 will face the other two card slots 606. At this time, the second spring 605 will contract and drive the card plate 603 toward The other two card slots 606 move and engage with the other two card slots 606, and the protective plate 602 cannot move at this time. At this time, the power socket and the air pipe interface on the bursting strength tester body 1 are shielded and protected by the connecting frame 601 and the protective plate 602, so as to prevent dust from entering the interior of the bursting strength tester body 1 from the air pipe interface, and to prevent dust from accumulating at the power socket, thereby ensuring the stable operation of the bursting strength tester body 1 and improving its safety in use;

[0041] When the baffle 7 needs to be disassembled, the limit block 805 can be pulled, and the limit block 805 drives the slider 802 to slide on the rotating shaft 801, and the third spring 804 stretches. When the limit block 805 and the groove 806 are not engaged, the rotating shaft 801 can be rotated, and the rotation of the rotating shaft 801 will drive the limit plate 803 to rotate together. When the rotating shaft 801 rotates ninety degrees, the third spring 804 will contract to make the limit block 805 engage with the groove 806 again. At this time, the rotating shaft 801 cannot continue to rotate, and the limit plate 803 is also not engaged with the bursting strength tester body 1. Then the baffle 7 can be removed from the bursting strength tester body 1, thereby realizing the rapid disassembly of the baffle 7, and then facilitating the inspection and maintenance of the bursting strength tester body 1.
