[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-Figure 4 The utility model provides a technical solution: a negative pressure adsorption cleaning fixture, including a mounting plate 1, one end of a movable plate 2 is connected to the mounting plate 1, a support column 3 is fixed to the lower side of the other end of the movable plate 2, a movable frame 4 is also connected to the movable plate 2, suction cups 5 are fixed on the movable frame 4 and the mounting plate 1, a connection port 6 connected to an air pipe is installed on the suction cup 5, and a support rod 7 is also connected to the movable plate 2.

[0022] The movable plate 2 is rotatably connected to the mounting plate 1, and four groups of movable plates 2 are provided, and the movable plate 2 is fixed to the mounting plate 1 by a first bolt 201; a rolling ball 301 is installed at the lower end of the support column 3, and the lower end surface of the ball 301 is flush with the lower end surface of the mounting plate 1; the movable frame 4 is slidably connected to the movable plate 2, and the upper end surface of the movable frame 4 is flush with the upper end surface of the mounting plate 1; a convex block 401 is also fixed to the movable frame 4, and the convex block 401 is nested in the movable plate 2 and can slide, and the movable frame 4 and the movable plate 2 are locked by a second bolt 402;

[0023] When using the negative pressure adsorption cleaning fixture, Figure 1-Figure 4As shown, by placing the device, the mounting plate 1 and the ball 301 are in contact with the desktop, and the air pipe is connected to the connecting port 6. When fixing the product, first adjust the position of the movable plate 2 and the suction cup 5 on the movable plate 2 according to the shape (square or round) size of the product. The movable plate 2 can be adjusted by the rotation between the movable plate 2 and the mounting plate 1. In the adjustment process, the movable plate 2 can be moved conveniently with the rolling action of the ball 301. After adjustment, it can be locked by the first bolt 201. Then, the position of the movable frame 4 and the suction cup 5 on the movable plate 2 can be adjusted by the sliding action between the protrusion 401 and the movable plate 2, so as to meet the needs of fixing products of different sizes. After adjustment, it can be locked by the second bolt 402 to ensure the stability of the device.

[0024] The support rod 7 and the movable plate 2 are distributed in a one-to-one correspondence, and the support rod 7 and the movable plate 2 are slidably connected; a rubber ball 701 is fixed to the upper end of the support rod 7, and the height of the rubber ball 701 is higher than the height of the suction cup 5, and a limit plate 702 is fixed to the lower end of the support rod 7, and the limit plate 702 is located below the movable plate 2; one end of a spring 8 is also fixed to the support rod 7, and the other end of the spring 8 is fixed to the movable plate 2;

[0025] When fixing the product, Figure 1-Figure 4 As shown, the product is placed. At this time, the product first contacts the rubber ball 701. With the support of the support rod 7 and the spring 8, the product can be placed in mid-air to avoid direct contact and positioning between the product and the suction cup 5, which makes it inconvenient to adjust the product position. After adjusting the product position, the product is pressed. At this time, the support rod 7 is forced to slide downward until the product contacts the suction cup 5. The suction cup 5 is then vacuumed to achieve the adsorption and fixation of the product, so as to facilitate the cleaning and positioning of the product. After the product is cleaned, the vacuum adsorption state of the suction cup 5 can be released by inflation. At this time, the support rod 7 is reset under the action of the spring 8, so that the product and the suction cup 5 can be automatically separated, thereby facilitating the product to be taken. This is the working principle of the negative pressure adsorption cleaning fixture.
