Compared with traditional wet vacuum pumps, the dry screw vacuum machine does not use oil, so it is environmentally friendly and has a longer service life.

[0003] Although existing dry screw vacuum machines are all directly installed on the mounting frame with bolts, the mounting holes on the mounting frame limit the installation, resulting in inaccurate alignment between components, making it impossible to make a reasonable layout according to needs. At the same time, the bolts may fall off due to vibration during the operation of the equipment, thus affecting the normal use of the equipment. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1-6 , the present utility model provides a technical solution: a dry screw vacuum unit, including: a support frame 1, a mounting plate 2, a dry screw vacuum machine body 3, a sliding groove 4, a connecting and fixing frame 5, a lead screw 6, a threaded rod 7, an internally threaded sleeve block 8, a connecting plate 9, a connecting rod 10, a connecting sleeve block 11, a first spring 12, a telescopic rod 13, a limiting block 14, a limiting insertion rod 15, and a second spring 16.

[0027] First, as shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 , since the dry screw vacuum machine body 3 is fixedly installed on the top of the mounting plate 2, the dry screw vacuum machine body 3 is placed on the top of the support frame 1 through the mounting plate 2, and then the connecting and fixing frame 5 is adjusted according to the installation position on the frame of the support frame 1. Thus, by respectively rotating the threaded rod 7, since a sliding groove 4 is opened on the top of the mounting plate 2, and the sliding groove 4 is symmetrically arranged left and right about the vertical central axis of the mounting plate 2, and the sliding groove 4 is symmetrically arranged front and back about the vertical central axis of the mounting plate 2. At the same time, a connecting and fixing frame 5 is slidably connected inside the sliding groove 4, and the connecting and fixing frame 5 is fixedly connected to the internally threaded sleeve block 8 on the rod body of the threaded rod 7. Then, since the connecting and fixing frame ⑤ is arranged in an "L" - shaped structure state, by rotating the threaded rod 7, the internally threaded sleeve block 8 drives the connecting and fixing frame 5 to slide inside the sliding groove 4, so that the connecting and fixing frame 5 slides to a state corresponding to the mounting hole on the frame of the support frame 1. Then, the lead screw <6> is placed on the horizontal plate body of the connecting and fixing frame 5, so that the lead screw 6 passes through the mounting plate 2 and corresponds to the mounting hole on the support frame 1. It can be seen that by adjusting the position of the connecting and fixing frame 5, the mounting plate 2 can be installed according to different installation environments and actual requirements, making the installation between the mounting plate 2 and different support frames 1 smoother, thereby increasing the flexibility and adaptability of the equipment;

[0028] As shown in Figure 2 , Figure 4 and Figure 6As shown, after aligning the installation plate 2 with the positions of the installation holes on the support frame 1, it is then fixedly installed on the vertical plate body of the connection fixing frame 5 through the connection plate 9. A connecting rod 10 is also slidably connected to the plate body of the connection plate 9. Since a first spring 12 is sleeved and connected to the outer side of the lower end of the connecting rod 10 with respect to the plate body of the connection plate 9, and a connection sleeve block 11 is fixedly installed at the lower end of the rod body of the connecting rod 10, the connection sleeve block 11 is arranged in a corresponding state with the lead screw 6. Also, the inner diameter of the connection sleeve block 11 is the same as the outer diameter of the lead screw 6. Thus, the elastic force of the first spring 12 drives the connection sleeve block 11 to be sleeved on the outer side of the lead screw 6 in the initial state. Then, by rotating the connecting rod 10, the connection sleeve block 11 drives the lead screw 6 to rotate and be fixedly connected to the frame body of the support frame 1. Through the simple installation process, the operator can install more quickly, and thus also avoids the operator's dependence on other tools;

[0029] As shown in the attached Figure 4 , the attached Figure 5 and the attached Figure 6 As shown, after the dry screw vacuum machine body 3 is fixed to the support frame 1 through the installation plate 2, since the initial velocity state of the limit block 14 is not set in a clamped state with the rod body of the connecting rod 10, and due to the elastic force of the first spring 12, the connection sleeve block 11 is sleeved on the outer side of the lead screw 6. Then, the elastic force of the telescopic rod 13 drives the limit block 14 to expand and contract and be in a corresponding state with the upper end rod body of the connecting rod 10. Since the limit block 14 is arranged in a "U"-shaped structure state, the limit block 14 is sleeved on the outer side of the rod body of the connecting rod 10. Then, limit insertion rods 15 are slidably connected to both the left and right ends of the limit block 14, and the limit insertion rods 15 penetrate through the limit block 14. Also, a second spring 16 is sleeved and connected to the outer side of one end of the limit insertion rod 15 inside the limit block 14. When the limit block 14 approaches the rod body of the connecting rod 10 through the telescopic rod 13, the limit insertion rod 15 comes into contact with the rod body of the connecting rod 10. At the same time, when the limit block 14 slides to the designated position, the elastic force of the second spring 16 drives the limit insertion rod 15 to be clamped with the rod body of the connecting rod 10, thereby fixing the rod body of the connecting rod 10 and strengthening the lead screw 6, and further reducing the detachment and wear caused by vibration, thus improving the reliability of the equipment.
