DETAILED DESCRIPTION

[0035] The present invention will now be described in further detail with reference to the accompanying drawings.

[0036] See also Figure 1-6 As shown, in this embodiment, an ion pump power supply protection structure is provided, including a box body 1, a box cover 2 is detachably connected to the top, two movable blocks 12 are relatively slidably provided in the box body 1, and a cavity for installing a power supply body 15 is defined between the two movable blocks 12. Two groups of clamping mechanisms 9 for driving the two movable blocks 12 to move relative to each other are relatively provided in the box body 1. The clamping mechanism 9 includes a fixed rod 91, which is fixedly connected to the box body 1. Two rings 93 are relatively sleeved and slidably connected on the fixed rod 91. A first spring 94 is fixedly connected between the two rings 93. The first spring 94 is sleeved on the fixed rod 91. Two connecting rods 92, whose center positions are relatively crossed and rotatably connected, the first ends of the two connecting rods 92 are respectively hinged to the two rings 93, and the second ends of the two connecting rods 92 are hinged to the movable block 12.

[0037] Specifically, when the power supply body 15 needs to be installed in the cavity defined by the two movable blocks 12, the power supply is first placed in the approximate position. At this time, the power supply body 15 will generate an external force to spread the two movable blocks 12, and the power supply body 15 drives the two movable blocks 12 to move relatively away from each other. The movable blocks 12 drive the two connecting rods 92 to rotate relative to each other. As the connecting rod 92 rotates, the two rings 93 will be pulled to slide relative to each other on the fixed rod 91, so that the first spring 94 is stretched, and thereby a clamping force is applied to the movable block 12 through the elastic force of the first spring 94 and the action of the connecting rod 92, thereby fixing the power supply body 15. The overall structure is simple to operate and can fix power supply bodies 15 of different sizes, thereby improving the versatility of the device and facilitating the protection of the power supply body 15.

[0038] It should be noted that the elastic force of the first spring 94 can be changed according to actual conditions, the fixed connection method between the fixing rod 91 and the box body 1 is the existing technology, and the shape of the movable block 12 can also be adjusted according to the actual conditions of the power supply, which is not limited here.

[0039] In this embodiment, if Figure 5As shown, one end of the two rings 93 facing away from the first spring 94 is fixedly connected to the second spring 8, and the other end of the second spring 8 facing away from the ring 93 is fixedly connected to the inner wall of the box body 1. The second spring 8 is sleeved on the fixed rod 91. Specifically, when the ring 93 slides on the fixed rod 91, the second spring 8 will expand and contract with the movement of the ring 93. The setting of the second spring 8 further enhances the elastic adjustment ability of the clamping mechanism 9. It works in conjunction with the first spring 94 to more accurately adjust the position of the movable block 12 and more firmly clamp the ion pump power supply body 15.

[0040] In this embodiment, if Figure 4 and Figure 5 As shown, a slider 10 is fixedly connected to the bottom of the movable block 12 , and a sliding groove 11 for the slider 10 to slide is provided in the box body 1 .

[0041] In this embodiment, if Figure 4 As shown, the movable block 12 is fixedly connected to a fixed plate 14, and the fixed plate 14 is rotatably connected to an arc-shaped arc plate 13, and the first end of the arc plate 13 can fit with the movable block 12 and the power supply body 15. The movable block 12 is hinged with an elastic telescopic rod 7, and the end of the elastic telescopic rod 7 away from the movable block 12 is hinged to the second end of the arc plate 13. Specifically, in the initial position, the two arc plates 13 do not contact the movable block 12. When the power supply body 15 is placed in the cavity between the two movable blocks 12, the power supply body 15 slides along the arc surface of the arc plate 13 to between the two movable plates 73, and at the same time makes the arc plate 13 fit with the movable plate 73, and the arc plate 13 The elastic telescopic rod 7 drives the position change of the elastic telescopic rod 7. Similarly, when the power supply body 15 is separated from the cavity between the two movable blocks 12, the elastic telescopic rod 7 drives the arc plate 13 to reset. The design of the arc plate 13 and the elastic telescopic rod 7 can further limit and fix the ion pump power supply body 15, making its position in the cavity more stable. The arc plate 13 can fit the shape of the power supply body 15, providing a more comprehensive and tight wrapping effect, preventing the power supply body 15 from shaking in all directions. Especially for some irregularly shaped ion pump power supplies, it can better adapt to their appearance characteristics, further improving the fixing and protection capabilities of the protective structure for the ion pump power supply.

[0042] In this embodiment, if Figure 4 and Figure 6 As shown, the elastic telescopic rod 7 includes a fixed cylinder 71, which is hinged to the movable block 12, a movable plate 73 is movably provided in the fixed cylinder 71, and a movable groove 75 for the movable plate 73 to move is provided in the fixed cylinder 71, a third spring 72 is located in the movable groove 75 and is fixedly connected to the movable plate 73, a telescopic rod 74 passes through and is movably provided on the fixed cylinder 71, and is fixedly connected to the movable plate 73, and one end of the telescopic rod 74 facing away from the movable plate 73 is hinged to the second end of the arc plate 13.

[0043] In this embodiment, if Figure 1 and Figure 2 As shown, the box cover 2 is semi-enclosed and sleeved on the opening of the box body 1. The box cover 2 and the box body 1 are detachably connected by a buckle 3. Specifically, the design of the detachable box cover 2 facilitates the operation and maintenance of the ion pump power supply. At the same time, the connection between the semi-enclosed box cover 2 and the buckle 3 can effectively block the influence of adverse external environmental factors on the power supply, ensuring that the ion pump power supply works in a relatively clean and dry environment, which helps to extend its service life and improve its working reliability.

[0044] In this embodiment, if Figure 2 and Figure 3 As shown, an embedding block 16 is fixedly connected to the box cover 2, and an embedding groove 6 for the embedding block 16 to be embedded in the box body 1. Specifically, the cooperation between the embedding block 16 and the embedding groove 6 enhances the stability of the connection between the box cover 2 and the box body 1, so that the box cover 2 can block external impurities from entering the box body 1 while maintaining a good fixed state, avoiding leakage problems such as dust and water vapor caused by loose connection, and better protecting the ion pump power supply in the box body 1.

[0045] In this embodiment, if Figure 1 and Figure 2 As shown, the box body 1 is relatively penetrated by a wire hole 5 and a heat dissipation hole 4. Specifically, the wire hole 5 facilitates the wiring connection of the power supply, ensures the normal communication and power supply relationship between the power supply and the external equipment, and maintains the integrity of the protective structure; the setting of the heat dissipation hole 4 effectively solves the heat dissipation problem of the ion pump power supply, ensures that it works within a suitable temperature range, improves the working efficiency and reliability of the power supply, and extends its service life.

[0046] Working principle:

[0047] When the power supply body 15 needs to be installed in the cavity defined by the two movable blocks 12, the power supply is first placed in the approximate position. At this time, the power supply body 15 slides along the curved surface of the curved plate 13 to between the two movable plates 73, and at the same time makes the curved plate 13 fit with the movable plate 73. The curved plate 13 drives the elastic telescopic rod 7 to change its position. At the same time, the power supply body 15 will generate an external force to open the two movable blocks 12, and the power supply body 15 drives the two movable blocks 12 to move relatively away from each other. The movable block 12 drives the two connecting rods 92 to rotate relative to each other. As the connecting rod 92 rotates, the two rings 93 will be pulled to slide relative to each other on the fixed rod 91, so that the first spring 94 is stretched and the second spring 8 is compressed. Thus, through the elastic force of the two springs and the action of the connecting rod 92, a clamping force is applied to the movable block 12 to achieve the fixation of the power supply body 15. The overall structure is simple to operate and can fix power supply bodies 15 of different sizes, thereby improving the versatility of the device and facilitating the protection of the power supply body 15.
