Description

Technical Field

[0001] The utility model relates to the technical field of testing equipment, and particularly refers to a stepping protection tooling for the top of a refrigerator. Background Art

[0002] The force endurance performance of product components is an important basis for the stability and reliability of products. For details, reference can be made to the Chinese patent "An endurance test device for simulating manual stepping and its test method" with the patent application number CN202310016140.7.

[0003] For the stepping test on the top of the refrigerator, the test operator needs to step on the specified position on the top of the refrigerator packaging. Currently, there is no corresponding protection tooling on the market for this test, and the test operator steps directly on the top of the packaging without protection. On the one hand, since the total mass of the test operator with the load is about 100 kg, when stepping on the top of the refrigerator packaging and the top edge, without the protection tooling, the safety of the test operator cannot be guaranteed. On the other hand, currently, this test requires the cooperation of multiple test operators, which wastes manpower and time costs and has low test efficiency. Summary of the Utility Model

[0004] The first technical problem to be solved by the utility model is to provide a stepping protection tooling for the top of a refrigerator that can ensure the safety of the test operator in view of the current situation of the prior art.

[0005] The second technical problem to be solved by the utility model is to provide a stepping protection tooling for the top of a refrigerator that can improve the test efficiency.

[0006] The technical solutions adopted by the utility model to solve the above first and second technical problems are as follows: A stepping protection tooling for the top of a refrigerator, which is characterized by comprising:

[0007] A base, including two support frames arranged at intervals left and right. The area between the two support frames includes a climbing area and a test area arranged in sequence from front to back. The test area is used for placing the refrigerator packaging; and

[0008] A ladder assembly, located in the climbing area and connected between the two support frames.

[0009] For the convenience of processing the support frames, each support frame includes

[0010] A first vertical rod;

[0011] A first horizontal rod, the rear end of which is connected to the first vertical rod;

[0012] A second horizontal rod, arranged at intervals above the first horizontal rod, and the rear end of which is connected to the first vertical rod; and

[0013] The first diagonal rod extends obliquely upward from front to back, with its front end connected to the front part of the first crossbar and its back end connected to the front part of the second crossbar.

[0014] The described stepped component is connected between the front parts of the second crossbars of the two support frames and the first diagonal rod.

[0015] To facilitate the tester to climb to a height, the stepped component includes multiple first stepped plates arranged at intervals along the extension direction of the first diagonal rod, and the left and right ends of each first stepped plate are respectively connected to the first diagonal rods of the two support frames.

[0016] To improve the installation stability of each first stepped plate, the number of the first diagonal rods is two and they are arranged side by side, and are respectively connected to the front and back parts of each first stepped plate.

[0017] To facilitate the tester to stay at the top of the climbing area, there is also at least one second stepped plate, which is at the same height as the topmost first stepped plate and is connected behind the first stepped plate, and the left and right ends of the second stepped plate are respectively connected to the front parts of the second crossbars of the two support frames.

[0018] To further ensure the safety of the tester, each support frame also includes

[0019] A third crossbar, arranged at intervals above the second crossbar, with its back end connected to the first vertical rod;

[0020] A second vertical rod, with its bottom end connected to the front end of the first crossbar; and

[0021] A second diagonal rod, extending obliquely upward from front to back, with its front end connected to the top end of the second vertical rod and its back end connected to the front end of the third crossbar;

[0022] The second vertical rod, the second diagonal rod and the third crossbar together form a handrail.

[0023] To enhance the stability of the support frame, each support frame also includes a third vertical rod, and both ends of the third vertical rod are respectively connected to the middle parts of the second crossbar and the third crossbar.

[0024] To enhance the stability of the base, the base also includes a connecting rod, and both ends of the connecting rod are respectively connected to the top ends of the first vertical rods of the two support frames.

[0025] To facilitate the refrigerator packaging to enter and exit the test area, an opening for the refrigerator packaging to enter and exit the test area is formed by enclosing between the first vertical rods of the two support frames and the connecting rod.

[0026] To prevent the refrigerator packaging from tipping over from the opening during the test, a door body for opening and closing the opening is further included.

[0027] Compared with the prior art, the advantages of the present utility model are as follows: A protection tooling is composed of a base and a ladder assembly. After the tester climbs to the elevated area, the refrigerator packaging located in the test area can be subjected to a trampling test. On the one hand, the safety of the tester can be ensured during both the climbing and trampling processes; on the other hand, only one tester is required to quickly conduct the trampling test, which can improve the test efficiency.
