Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0023] like Figure 1 - Figure 4 As shown, this application provides a noise testing device for a blender, including: a test support frame 1, a lower cover 2 connected to the rear of the top of the test support frame 1, an upper cover 3 provided at the top of the lower cover 2, and a blender body 17 provided inside the lower cover 2.

[0024] Specifically, such as Figure 1 As shown, a safety light curtain 5 is installed at the top front of the test support frame 1, and a display module 4 is installed on one side of the safety light curtain 5. The display module 4 is used to display data, and the safety light curtain 5 is used to monitor the safety of the operator.

[0025] A protective component is provided on the outside of the lower cover 2. The protective component includes a tilting cylinder 8. An elastic connecting rod 11 is provided on the front side of the tilting cylinder 8. The protective component is used for sound insulation protection on the outside of the blender body 17.

[0026] Specifically, such as Figure 2 As shown, a connecting block 7 is connected to the outer side of the lower cover 2, and a flipping cylinder 8 is connected to the top of the connecting block 7. An adhesive pad 6 is connected to the bottom inner side of the upper cover 3, and connecting blocks 9 are connected to both ends of the upper cover 3. The flipping cylinder 8 is connected to the bottom of the connecting block 9. The extension and retraction of the flipping cylinder 8 controls the rotation of the upper cover 3 at the top of the lower cover 2.

[0027] Specifically, such as Figure 3As shown, both sides of the lower cover 2 are connected to positioning blocks 10, and elastic connecting rods 11 are connected to the inner side of positioning blocks 10. The elastic connecting rods 11 slide and adjust on the inner side of positioning blocks 10, which is used for the fixed connection between positioning blocks 10 and positioning blocks 14.

[0028] Specifically, such as Figure 3 As shown, a snap-fit ​​limiting block 12 is connected to the outer side of the elastic connecting rod 11, and a removable nut 13 is connected to the top of the elastic connecting rod 11. The end of the elastic connecting rod 11 is provided with threads to facilitate the removable nut 13 to be screwed and positioned.

[0029] Specifically, such as Figure 3 As shown, a positioning block 2 14 is connected to the outer side of the upper cover 3, and a gourd groove 15 is connected to the inner side of the positioning block 2 14. The gourd groove 15 facilitates the locking of the limiting block 12 after it passes through, and then the position of the elastic connecting rod 11 is moved to limit the movement.

[0030] A positioning component is provided on the inner side of the lower cover 2. The positioning component includes a fixing plate 19, and a squeezing plate 20 is provided on one side of the fixing plate 19. The positioning component is used for positioning adjustment of the blender body 17.

[0031] Specifically, such as Figure 4 As shown, a noise tester 16 is connected to the bottom inner side of the lower cover 2. A fixing plate 19 is fixedly connected to the bottom inner side of the lower cover 2. A guide rod 21 is connected to one side of the fixing plate 19. A squeezing plate 20 is connected to one side of the guide rod 21. A telescopic cylinder 18 is installed on one side of the squeezing plate 20. The telescopic cylinder 18 drives the squeezing plate 20 to move, and works with the fixing plate 19 to clamp and position the blender body 17.

[0032] In this embodiment: the lower cover 2 and the upper cover 3 are rotated and connected by a flipping cylinder 8. The connection is sealed and protected by an adhesive gasket 6 to improve the tightness of the connection. After connection, the positioning and fixing are achieved by tightening the easy-to-remove nut 13, which improves the efficiency of disassembly and assembly. When conducting noise testing on the blender body 17, the position of the blender body 17 is set with a fixing plate 19 and a squeezing plate 20 working together to squeeze and position it. The blender body 17 can be placed in two ways: reinforced or unreinforced. This tests whether reinforcement affects the noise test and improves the accuracy of the test data.

[0033] The specific solution is as follows: During use, the blender body 17 needs to be placed inside the lower cover 2 first. Then, the flip cylinder 8 is activated. Through the rotational connection between the flip cylinder 8 and the connecting block 2 9, as well as the rotational connection between the lower cover 2 and the upper cover 3, the lower cover 2 and the upper cover 3 are controlled to form a closed cover, isolating the blender body 17. After connection, the middle part is sealed by the rubber adhesive pad 6 to reduce the influence of external noise. Then, the outer positioning block 10 and positioning block 2 14 are brought closer together, so that the locking limit block 12 is locked inside the gourd groove 15. Then, the elastic connecting rod 11 is slid to form a connection limit. Finally, the easy-to-remove nut 13 is tightened. At this time, the noise tester 16 displays the noise generated by the blender body 17 through the display module 4 for real-time monitoring. The blender body 17 can also be positioned by the proximity of the fixing plate 19 and the extrusion plate 20. The impact of the fixing method on the noise generated by the blender body 17 can also be tested, improving the practicality of the equipment.
