[0024] In order to make the purpose, technical solutions and advantages of the embodiment of the present invention clearer, the following will be combined with the appended drawings of the embodiment of the present invention. Figure 1-5 , clearly and completely describing the technical solutions of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field fall within the scope of protection of the present invention.

[0025] like Figure 1-5As shown: This embodiment provides a multi-layer vacuum oven that is easy to adjust, including an oven body 100. Two groups of adjustment slots 104 are symmetrically provided on both sides of the inner wall of the oven body 100. The two groups of adjustment slots 104 are fixed to the inner wall of the oven body 100 by bolts or welding. A plurality of sliders 106 are slidably provided on the side ends of the two groups of adjustment slots 104. The plurality of sliders 106 can slide vertically in the adjustment slots 104. A plurality of slide racks 105 are provided between the side ends of the plurality of sliders 106. The slide racks 105 are fixed on the sliders 106 by welding. The slide racks 105 are used to clamp the tray in, thereby driving the tray to move up and down on the sliders 106. The slide frame 105 can be moved up and down, and the slide frame 105 can be indirectly adjusted up and down to adapt to the height of the items on the tray. At the same time, the space can be maximized and it is convenient to take out and place the tray. The side end of the slide frame 105 is provided with a limit assembly 200. The limit assembly 200 includes a plurality of limit slots 202 arranged on the side end of the adjustment slot 104. The interiors of the plurality of sliders 106 are all slidably provided with a clamping block 201. The clamping block 201 is plugged into the plurality of limit slots 202. The clamping block 201 can slide back and forth in the slider 106, and then can enter the plurality of limit slots 202, so that the slot can be limited.

[0026] If personnel place items of different heights on the tray, because the existing slide rack 105 is fixed, the space utilization rate will be low when placing items of different heights. Therefore, personnel drive the limiting component 200, so that the clamping block 201 inside the slider 106 slides, so that the clamping block 201 is separated from the multiple limiting slots 202, and then as the slider 106 moves in the slide rack 105, the slider 106 moves up or down, and then the limiting component 200 is driven again, so that the clamping block 201 can be re-entered into the limiting slot 202, so that the slide rack 105 can be adjusted, and at the same time, it can adapt to the placement of items of different heights on the tray, and at the same time, the internal space of the multi-layer vacuum oven can be better utilized.

[0027] Limiting component 200 Figure 3 The enlarged picture of point A is as follows Figure 4 As shown,

[0028] The limiting assembly 200 also includes a guide groove provided on the side end of the adjusting slot 104, and the guide groove is provided corresponding to the limiting slot 202. The side end of the slide frame 105 is provided with two fixed blocks 204, and the two fixed blocks 204 are fixed to the slide frame 105 by welding. The middle part of the fixed block 204 and the middle part of the side end of the slider 106 are both provided with a sliding rod 206, and the sliding rod 206 can slide back and forth on the fixed block 204. The sliding rod 206 passes through the middle through hole of the fixed block 204 and the middle through hole of the side end of the slider 106 and is connected to the side end of the card block 201. The middle part of the fixed block 204 and the slider 106 provides a front and rear guide for the sliding rod 206, and the guide groove provides an up and down guide for the sliding rod 206.

[0029] The limiting assembly 200 further includes a spring 205 disposed within the slider 106. The ends of the spring 205 are fixed to the side wall within the slider 106 and the side end of the clamping block 201, respectively. The spring 205 is sleeved on the outer surface of the sliding rod 206, and the spring 205 provides elastic support for the clamping block 201.

[0030] The limiting assembly 200 further includes a rotating block 203 hingedly mounted on the end of the sliding rod 206. The rotating block 203 is located at the side of the fixed block 204. The rotating block 203 can rotate on the sliding rod 206. When the rotating block 203 is in a vertical position, one side of the rotating block 203 contacts the side of the fixed block 204, thereby limiting the sliding rod 206. When the rotating block 203 is rotated again, so that the rotating block 203 is in a horizontal position, the sliding rod 206 is released from the limit.

[0031] When the cam 201 is in the closed position, the spring 205 in the slider 106 is retracted, and the clamping block 201 in the slider 106 is moved backward, so that the clamping block 201 is separated from the limit slot 202 on the adjustment slot 104. Then, the cam 203 on the sliding rod 206 is rotated, so that the cam 203 is in the vertical position and contacts one side of the fixed block 204, so that the cam 201 can be freely adjusted to slide, so that the spacing of the limit slot 202 can be adjusted according to different items. Then, the support plate is inserted into the adjustment limit slot 202 to adjust to the appropriate spacing, and the cam 203 is rotated again. Then, the spring 205 rebounds and provides elastic support for the clamping block 201, so that the cam 201 is limited, which indirectly saves space inside the multi-layer vacuum oven.
