Description

Technical Field

[0001] This patent relates to the technical field of test benches, and specifically to a multi-functional rotary test bench. Background Art

[0002] In order to facilitate the taking and placing of test items on the tabletop of the existing test bench, the overall test bench is set to be rotatable. However, there is a lack of a fixing structure on the tabletop of the test bench. When a person accidentally touches the tabletop, it is very easy for the tabletop to rotate randomly, affecting the progress of the test. Moreover, the existing test bench has a single function and poor practicability. Therefore, we propose a multi-functional rotary test bench.

[0018] The following will clearly and completely describe the technical solutions in the embodiments of this patent with reference to the accompanying drawings in the embodiments of this patent. Obviously, the described embodiments are only a part of the embodiments of this patent, rather than all the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this patent.

[0019] Please refer to Figure 1 , Figure 2 and Figure 3 This patent provides a technical solution: a multifunctional rotary test bench, including a base 1. A circular groove 2 is provided in the middle of the top of the base 1. The inner side wall of the circular groove 2 is fixedly installed with a first bearing 3. The top end of the inner ring of the first bearing 3 is fixedly installed with a column 4. The top end of the column 4 is fixedly installed with a tabletop 5. A ring groove 6 is provided at the bottom of the tabletop 5. A rubber ring 7 is fixedly installed in the ring groove 6;

[0020] A slide groove 8 is provided on the right side of the top of the base 1. The inner bottom wall of the slide groove 8 is fixedly installed with a spring 9. The top end of the spring 9 is fixedly installed with a slide block 10. The slide block 10 is slidably installed on the inner side wall of the slide groove 8. The top end of the slide block 10 is fixedly installed with a vertical rod 11. The top end of the vertical rod 11 is fixedly installed with a rubber pad 12. The top of the rubber pad 12 is closely attached to the bottom of the rubber ring 7;

[0021] Figure 1 The spring 9 shown is in a compressed state. Through the compression effect of the spring 9, the top of the rubber pad 12 is pressed tightly against the bottom of the rubber ring 7.

[0022] The bottom of the rubber ring 7 is provided with tooth grooves 13 distributed continuously in a circle. The top of the rubber pad 12 is integrally formed with inserted teeth 14. The shape and size of the inserted teeth 14 match the internal shape and size of the tooth grooves 13. The inserted teeth 14 are inserted into the tooth grooves 13;

[0023] By setting the inserted teeth 14 inserted into the tooth grooves 13, the pressing effect of the rubber pad 12 on the rubber ring 7 can be further increased.

[0024] On the upper left side of the tabletop 5, there is a feeding opening 25. A cover 26 is hinged on the feeding opening 25. At the bottom of the feeding opening 25, a feeding pipe 27 is fixedly installed. At the right end of the outer sidewall of the feeding pipe 27, a clamping rod 28 is fixedly installed. Below the feeding pipe 27, there is a waste bin 29. At the right end of the top of the waste bin 29, a vertical plate 30 is integrally formed. There is a card slot at the rear end of the vertical plate 30, and the clamping rod 28 is clamped in the card slot.

[0025] As Figure 1 shown, the card slot is arranged at the rear side position of the vertical plate 30. The waste bin 29 can be moved forward to disassemble the vertical plate 30 and the clamping rod 28.

[0026] A special test waste plastic bag can be sleeved inside the waste bin 29.

[0027] Specifically, the column 4 includes a column body 15 and a second bearing 16. The bottom end of the column body 15 is fixedly installed at the top end of the inner ring of the first bearing 3. The top end of the column body 15 is fixedly installed at the middle part of the bottom of the tabletop 5. The inner sidewall of the inner ring of the second bearing 16 is fixedly installed on the sidewall of the column body 15. At both the left and right ends of the outer sidewall of the outer ring of the second bearing 16, a support rod 17 is fixedly installed. The bottom end of the support rod 17 is fixedly installed at the top of the base 1.

[0028] As Figure 1 shown, when the side part of the tabletop 5 is accidentally impacted, it is easy to cause damage to the connection between the bottom end of the column 4 and the first bearing 3. By setting the support rod 17 and the second bearing 16, the support and compression resistance effect of the column 4 can be increased.

[0029] Specifically, at the right end of the inner sidewall of the chute 8, there is a rectangular opening 18. At the right end of the sidewall of the slider 10, a foot pedal 19 is fixedly installed. The right end of the foot pedal 19 extends through the rectangular opening 18 to the right side of the base 1.

[0030] The setting of the foot pedal 19 can facilitate the operator to control the slider 10 with the foot.

[0031] Specifically, it further includes a rubber sheet 20. The outer sidewall of the rubber sheet 20 is fixedly installed on the inner sidewall of the rectangular opening 18. There is a mounting hole on the rubber sheet 20, and the inner sidewall of the mounting hole is fixedly installed on the sidewall of the foot pedal 19.

[0032] As Figure 1 shown, the rubber sheet 20 is in a wrinkled state. The position of the rectangular opening 18 can be blocked by the rubber sheet 20 to prevent the soil on the operator's foot from entering the chute 8 through the rectangular opening 18 and affecting the sliding effect of the slider 10. And the deformable characteristic of the rubber itself can adapt to the up and down movement of the foot pedal 19.

[0033] Specifically, the slider 10 includes a block 21. An installation groove 22 is provided on the side wall of the block 21. A roller 23 is connected in the installation groove 22 through a rotating shaft. A wheel groove 24 is provided on the inner side wall of the chute 8. The roller 23 is rotatably installed in the wheel groove 24, and the side wall of the block 21 does not contact the inner side wall of the chute 8.

[0034] By setting the roller 23 to be rotatably installed in the wheel groove 24, the sliding property of the slider 10 moving up and down can be increased, and the friction can be reduced.

[0035] Working principle: For example, a tester sits on one side of the tabletop 5 through a chair for the test. When it is necessary to rotate the tabletop 5, the tester can step on the foot pedal 19 downward with the foot, thereby driving the slider 10 and the vertical rod 11 to move downward. The rubber pad 12 is separated from the rubber ring 7, and then the tabletop 5 is rotated. After the rotation is completed, the foot pedal 19 is released. Through the rebounding effect of the spring 9, the top of the rubber pad 12 is pressed against the bottom of the rubber ring 7 again, and at the same time, the spline teeth 14 are inserted into the tooth grooves 13 at different positions.

[0036] It should be noted that the device structure and the drawings of this patent mainly describe the principle of this patent. In terms of the technical design principle, the settings of the power mechanism, power supply system, control system, etc. of the device are not fully described clearly. On the premise that those skilled in the art understand the principle of the above patent, the specific details of its power mechanism, power supply system, and control system can be clearly obtained.
