DETAILED DESCRIPTION

[0030] The technical scheme in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the scope of protection of the utility model.

[0031] REFERENCE Figs. 1-2The utility model provides an embodiment: a vacuum drying machine drying tray protection frame, including bottom plate 1, bottom plate 1 top four corner places fixedly connected with side frame 2, the side frame 2 opposite side all are seted up with a plurality of recessed holes 3, be provided with adjusting mechanism between side frame 2, the symmetrical side frame 2 between fixedly connected with crossbeam 13, the crossbeam 13 bottom is provided with limiting mechanism, bottom plate 1 with crossbeam 13 between fixedly connected with limiting post 14, bottom plate 1 top fixedly connected with fixed frame 21, adjusting mechanism includes sliding frame 4, sliding frame 4 slidingly connected between side frame 2, the fixedly connected with locating block 6 in side frame 2, the sleeve 7 of locating block 6 side wall fixedly connected with, slidingly connected with slider 8 in sliding frame 4, sliding frame 4 inside is provided with spring 9, slider 8 side wall fixedly connected with connecting rod 10, connecting rod 10 side wall fixedly connected with clamping block 11, clamping block 11 slidingly connected in recessed hole 3, sliding frame 4 side wall fixedly connected with groove plate 5, slider 8 side wall fixedly connected with handle 12, handle 12 side wall slidingly connected in sliding frame 4, spring 9 one end fixedly connected in sleeve 7, spring 9 other end fixedly connected in slider 8 side wall,

[0032] When needing to adjust the interval between drying trays, the operator can hold the handle 12 simultaneously, and slide to the middle direction. With the movement of the handle 12, the slider 8 is driven to slide to the middle in the sliding frame 4. In this process, the slider 8 gradually extrudes the spring 9, and the spring 9 is deformed under the pressure, and simultaneously drives the clamping block 11 to slide inwards and gradually disengage from the originally clamped recessed hole 3. At this time, the continuous sliding of the handle 12 makes the clamping block 11 completely enter the inside of the sliding frame 4, so as to release the fixed state. After releasing the fixed state, the user can slide the whole sliding frame 4 up and down to realize the adjustment of the interval between the drying trays. When reaching the required interval position, the operator gradually releases the handle 12. The spring 9 starts to slowly reset under the action of its own elastic force, so that the slider 8 and the clamping block 11 stably return to the initial state. With the gradual release of the spring 9, the clamping block 11 is gradually pushed to the outside of the sliding frame 4, and finally clamps and fixes with the recessed hole 3 corresponding to the current height, to form a reliable locking effect.

[0033] Referring to Figs. 1-3 , the limiting mechanism includes a top plate 15, the top plate 15 is fixedly connected to the bottom of the crossbeam 13, the top plate 15 is internally provided with a sliding groove 16, the top plate 15 is internally provided with a sliding column 18, the sliding column 18 is slidingly connected to the inside of the sliding groove 16, the sliding column 18 is fixedly connected with a baffle 17, the baffle 17 is slidingly connected to the inside of the top plate 15, the baffle 17 is fixedly connected with a handle 20 on one side, the baffle 17 is fixedly connected with a clamping plate 19 on the other side, and the clamping plate 19 is clamped with the fixed frame 21.

[0034] In operation using the device, first, the deflector 17 is deflected by pulling the handle 20 to separate the clamping plate 19 from the fixed frame 21, which not only ensures the smooth separation of the clamping plate 19 from the fixed frame 21, but also effectively creates space for subsequent operations. Then, the operator turns the deflector 17 upward and pushes the slide column 18 into the interior of the sliding slot 16, and then places the baking tray between the groove plates 5, ensuring the stability of the baking tray. Next, the deflector 17 is pulled out from the interior of the top plate 15 and turned to the original position again. At this time, the clamping plate 19 and the fixed frame 21 are re-engaged to fix the baking tray to prevent it from falling off during operation.

[0035] Working principle: In operation using the device, first, the deflector 17 is deflected by pulling the handle 20 to separate the clamping plate 19 from the fixed frame 21, then the deflector 17 is turned upward and the slide column 18 is pushed into the interior of the sliding slot 16, at the same time the deflector 17 is sent into the interior of the top plate 15, then the baking tray is placed between the groove plates 5, after placement, the deflector 17 is pulled out from the interior of the top plate 15 and turned downward, the clamping plate 19 and the fixed frame 21 are re-engaged to limit the baking tray from falling off the groove plates 5;

[0036] When the distance between the baking trays needs to be adjusted, the handles 12 on both sides are simultaneously slid inward, driving the sliding blocks 8 to slide inward in the sliding frame 4, extruding the springs 9 to deform, and making the clamping blocks 11 slide into the interior of the sliding frame 4, then the sliding frame 4 is slid up and down to change the distance between the baking trays. When the distance is determined, the handles 12 are gradually loosened outward, the springs 9 are gradually reset, and the clamping blocks 11 are repositioned to the outside of the sliding frame 4, so that the clamping blocks 11 are inserted into the recessed holes 3 corresponding to the current height.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features, as long as they are within the spirit and principles of the present application. Any modification, equivalent substitution, improvement, etc. made within the scope of the present application shall be included in the protection scope of the present application.
