[0034] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0035] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. These are merely examples and are not intended to limit the scope of the invention. Furthermore, reference numerals and / or letters may be repeated in different examples; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various embodiments and / or arrangements discussed. In addition, examples of various specific processes and materials are provided in this invention, but those skilled in the art will recognize the application of other processes and / or the use of other materials.

[0036] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example

[0037] See Figure 1 and Figure 2This embodiment discloses a frame for a vacuum pump unit, including a bottom support 10, a top support 20, and a support member 30. The bottom support 10 and the top support 20 are both set on a horizontal plane, with the top support 20 located above the bottom support 10. The bottom support 10 and the top support 20 are connected by the support member 30.

[0038] Specifically, one end of the bottom support 10 has an open structure, through which the small vacuum pump unit 40 can be pushed into the bottom support 10. A support part is provided in the middle of the bottom support 10, and after the small vacuum pump unit 40 is pushed into the bottom support 10, the small vacuum pump unit 40 is located on the support part.

[0039] Multiple support members 30 are installed between the top bracket 20 and the bottom bracket. The support members 30 are arranged vertically, and there is a gap between adjacent support members 30. When the small vacuum pump unit 40 is pushed into the bottom bracket 10, the electrical control box of the small vacuum pump unit 40 is located between two support members 30. The aforementioned large Roots vacuum pump 50 is installed on the top of the top bracket 20, and its installation direction is perpendicular to that of the small vacuum pump unit 40, thereby preventing pipelines from blocking the door of the electrical control box of the small vacuum pump unit 40.

[0040] Preferably, there is a gap between the support and the ground, which facilitates the movement of the entire unit. Additionally, a ramp is provided at the end of the support, located at the open structure of the bottom bracket 10. This ramp facilitates pushing the small vacuum pump unit 40 onto the support.

[0041] In this embodiment, a bottom support 10 is provided on the frame, and one end of the bottom support 10 is designed as an open structure, so that the small vacuum pump unit 40 set on the support can be moved out for maintenance, and a dedicated position is designed for the electrical control box of the small vacuum pump unit 40 to facilitate daily debugging.

[0042] In one specific embodiment:

[0043] The bottom support 10 includes three profiles 11, 12, and 13, four wheels 14, a support rod 15, two support plates 16, and a guide plate 17. One end of profile 11 is perpendicularly connected to one end of profile 12, and the other end of profile 12 is perpendicularly connected to one end of profile 13. The three profiles 11, 12, and 13 form a U-shaped structure.

[0044] A wheel 14 is provided at each end of the profile 11 and a wheel 14 is provided at each end of the profile 13, so that the U-shaped structure formed by the three profiles 11, 12 and 13 can move freely. The wheel 14 is a universal wheel.

[0045] There are two support rods 15, which are arranged parallel to each other and are both set in the U-shaped structure formed by three profiles 11, 12 and 13. One end of the support rod 15 is fixedly connected to one end of the profile 11, and the other end of the support rod 15 is connected to one end of the profile 13. The two support rods 15 are respectively fixedly set at both ends of the profiles 11 and 13.

[0046] The middle of the support rod 15 has a recessed structure, making both ends of the support rod 15 L-shaped. Two support plates 16 are arranged parallel to each other on the two support rods 15, and the support plates 16 are perpendicular to the support rods 15. The support plates 16 are arranged parallel to the profiles 11 and 13, so that one end of the support plate 16 is located at the open structure of the U-shaped structure formed by the three profiles 11, 12, and 13, and one end of the guide plate 17 is connected to this end of the support plate 16. The guide plate 17 is positioned so that one end of the support plate 16 is on the ground, which facilitates guiding the small vacuum pump unit 40 onto the support plate 16.

[0047] In this embodiment, the support rod 15 and the support plate 16 constitute the support part, and the guide plate 17 constitutes the ramp. During operation, the small vacuum pump unit 40 is pushed onto the support plate 16 by the guide plate 17, so that the small vacuum pump unit 40 is located in the U-shaped structure composed of three profiles 11, 12 and 13.

[0048] The bottom of the small vacuum pump unit 40 is equipped with guide wheels 41 and support feet 42. The cross-section of the support plate 16 is L-shaped, and the corner sides of the cross-sections of the two support plates 16 are close to each other. So when the small vacuum pump unit 40 is pushed onto the support plate 16, the L-shaped structure of the support plate 16 can limit the guide wheels 51 at the bottom of the small vacuum pump unit 40. After the small vacuum pump unit 40 enters the U-shaped structure, it is supported on the top surface of the support plate 16 (15) by the support feet 42, so as to prevent the small vacuum pump unit 40 from moving.

[0049] In another specific embodiment:

[0050] The bottom support 10 also includes four adjusting feet 18. One adjusting foot 18 is provided at each end of the profile 11, and one adjusting foot 18 is provided at each end of the profile 13. The four adjusting feet 18 are located near the four wheels 14. By adjusting the height of the adjusting feet 18 after the machine frame has moved the unit to a suitable position, the position of the machine can be fixed by adjusting the height of the adjusting feet 18.

[0051] In another specific embodiment:

[0052] A support member 30 is vertically installed on one end of profile 11 connected to profile 12, and a support member 30 is vertically installed on one end of profile 13 connected to profile 12. A support member 30 is also installed in the middle of profiles 11 and 13. A total of four support members 30 support the top bracket 20 on the bottom bracket 10. These four support members 30 provide stable support and ample space for the electrical control box of the small vacuum pump unit 40. The electrical control box of the large Roots vacuum pump 50 can be directly mounted on the support members 30.

[0053] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
