DETAILED DESCRIPTION

[0020] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0021] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0022] This embodiment mainly describes the structure of the operating table, which is as follows:

[0023] Embodiment: metallographic grinding and polishing table, such as Figure 1-2 As shown, it includes an operating table 1, a first support seat 2, a second support seat 3 and a lifting component for adjusting the working height of the metallographic grinding and polishing machine. The operating table 1 has two symmetrical grooves, and there are two first support seats 2 symmetrically in the grooves. The first support seat 2 is fixedly connected to the groove of the operating table 1. There are two second support seats 3 symmetrically in the grooves. The second support seat 3 is fixedly connected to the groove of the operating table 1, and the second support seat 3 is located on the inner side of the two first support seats 2. The operating table 1 is installed with a lifting component for adjusting the working height of the metallographic grinding and polishing machine. The lifting component includes a limit rod 4, a rotating rod 4, and a lifting rod 5. The movable sleeve 5, roller 6, worm wheel 7, screw 8, worm 9 and lifting plate 10, there are four limit rods 4, the limit rods 4 are fixedly connected to the operating table 1, the rotating sleeve 5 is rotatably connected to the second support seat 3, and the rotating sleeve 5 located in the second support seat 3 is fixedly connected with the roller 6 for reducing friction, the rotating sleeve 5 is fixedly connected with the worm wheel 7, the rotating sleeve 5 is threadedly connected with the screw 8, the upper end of the screw 8 is connected with the lifting plate 10, the four limit rods 4 respectively penetrate the lifting plate 10, the worm 9 is rotatably connected to the two first support seats 2, and the worm 9 is meshed with the two worm wheels 7. The lifting plate 10 is made of PVC, which can meet the requirements of the lifting plate 10 in terms of waterproof, oil-proof and anti-fouling performance.

[0024] Before using the operating table 1, the operator first uses the lifting assembly to adjust the height of the operating table 1. The operator first manually rotates the worm 9 clockwise. At this time, the worm 9 drives the worm wheel 7 to rotate clockwise, and the worm wheel 7 drives the rotating sleeve 5 to rotate clockwise. During the rotation of the rotating sleeve 5, the roller 6 fixed on the rotating sleeve 5 reduces the friction between the rotating sleeve 5 and the second supporting seat 3. The rotating sleeve 5 is threadedly connected with the screw rod 8. At this time, the rotating sleeve 5 drives the screw rod 8 to rise. After the operator adjusts the height to a suitable height, because the worm wheel 7 and worm 9 mechanism have a self-locking function, the operator can directly loosen the worm 9 to complete the height adjustment. The lifting assembly plays a role in height adjustment, so that operators of different heights can choose a suitable operating height according to their height when using the metallographic operating table 1.

[0025] like Figure 3 As shown, it also includes a brake assembly for limiting the worm 9, the brake assembly includes a brake handle 11, a rubber block 12 and an elastic member 13, the brake handle 11 is slidably connected to the first support seat 2, one end of the brake handle 11 is fixedly connected to the rubber block 12, an elastic member 13 is wound between the first support seat 2 and the brake handle 11, one end of the elastic member 13 is fixedly connected to the brake handle 11, and the other end of the elastic member 13 is fixedly connected to the first support seat 2.

[0026] In order to prevent the operator from accidentally touching the worm 9 during operation, a brake assembly is added. When there is no need to adjust the operating platform 1, the rubber block 12 on the brake handle 11 is tightly attached to the worm 9, which brakes the worm 9. The elastic member 13 is in a semi-tensioned state at this time. When it is necessary to adjust the height of the operating platform 1, the operator needs to first pull the brake handle 11 outward by one end. At this time, the rubber block 12 tightly attached to the worm 9 releases the limit on the worm 9, and the elastic member 13 is fully tensioned. After the adjustment is completed, the operator releases the brake handle 11, and the elastic member 13 returns to a semi-tensioned state. The brake assembly brakes the worm 9, thereby preventing the lifting plate 10 from being displaced during operation.

[0027] like Figure 1 As shown, a rubber ring 14 is also included, and the rubber ring 14 is fixedly connected to the worm 9.

[0028] When the worm 9 is operated to rotate, the rubber ring 14 fixedly connected to the handle of the worm 9 can increase the friction between the hand and the worm 9, thereby increasing the rotational manipulability of the worm 9.

[0029] like Figure 1 As shown, a hook 15 is also included, and the hook 15 is fixedly connected to the left side of the operating platform 1.

[0030] The hook 15 fixedly connected to the left side of the operating table 1 can be used to hang some rags or tools, thereby improving the storage capacity of the operating table 1.

[0031] like Figure 1 As shown, it also includes a moving wheel 16, which is fixedly connected to the bottom of the operating platform 1.

[0032] When the device needs to be transported, the operator can push the operating platform 1 to move, and the moving wheels 16 fixedly connected to the bottom of the operating platform 1 can increase the transportability of the operating platform 1.

[0033] like Figure 1 As shown, an anti-skid pad 17 is also included, and the anti-skid pad 17 is fixedly connected to the lifting plate 10.

[0034] In the process of the lifting plate 10 rising or falling, in order to prevent the metallographic grinding and polishing machine from being displaced, an anti-skid pad 17 is added, which has the effect of increasing the stability of the device on the lifting platform during the lifting process.
