Description

Technical Field

[0001] This utility model relates to the field of agricultural product drying and storage technology, and in particular to a raisin drying rack. Background Technology

[0002] Raisins are a food made by dehydrating grapes using the heat of the sun or artificial heating. They are high in sugar and are a typical high-energy nutritional product. Raisins have low water content, making them easy to transport and store. The most important grape for making raisins around the world is the green seedless grape variety, Muscat Blanc. Other varieties for making raisins include Muscat Blanc and Corinthian Black.

[0003] In traditional raisin drying racks, trays are usually placed at the bottom of the shelves to collect fallen raisins and crumbs. However, since the existing trays are mostly installed using bolts or welding, disassembly requires tools such as wrenches and screwdrivers, which is time-consuming and laborious, thus affecting the cleaning effect and reducing the user's work efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that it is not convenient to replace or clean the trays when using raisin drying racks. Therefore, we propose a raisin drying rack.

[0005] To achieve the above objectives, this application adopts the following technical solution: a raisin drying rack, comprising a base plate, with supports fixed on both sides of the top of the base plate, two connecting rods slidably connected inside the supports, a shelf fixed to one end of each connecting rod, a tray inside the shelf, a fixing block fixed to the front end of the tray, a housing at the front end of the shelf, a knob threadedly connected inside the housing, a limit block fixed to one end of the knob inside the housing, a movable plate slidably connected inside the housing, an insert plate fixed to the bottom of the movable plate, and a slot for cooperating with the insert plate on the top of the fixing block.

[0006] Preferably, a first spring is fixed at both ends on one side of the movable plate, and the other end of the first spring is fixed to the inside of the housing.

[0007] Preferably, the limiting block is elliptical in shape, and the difference between the maximum and minimum diameters of the limiting block is greater than the distance the insert plate is inserted into the slot.

[0008] Preferably, guide rods are fixed on both sides inside the housing, and grooves that cooperate with the guide rods are provided at both ends of the movable plate.

[0009] Preferably, the surface of the knob is provided with a gasket, and the gasket is made of rubber.

[0010] Preferably, a slide rod is slidably connected to one end of the connecting rod, a cross plate is fixed to the other end of the slide rod, and insert rods are fixed to both ends of one side of the cross plate. A plurality of insertion holes for use with the insert rods are opened on one side of the bracket. A second spring is fixed inside the connecting rod, and the other end of the second spring is fixed to the slide rod.

[0011] Preferably, the connecting rod has sliding grooves on both sides inside, and the sliding rod has sliders fixed on both sides to cooperate with the sliding grooves.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, by turning the knob, the limiting block fixed to it is rotated, causing it to move away from the moving plate. At this time, the moving plate will be subjected to the rebound force of the first spring and move upward, causing the insert plate to disengage from the inside of the slot, releasing the fixing block. Then, the user can easily pull the handle to pull the tray out of the shelf, which makes it easy to clean, avoids fruit residue or sugar residue remaining on the corners of the tray, and reduces the risk of mold growth. The above structure is simple to operate, requires no special tools, and the tray can be replaced separately without overall maintenance, reducing the cost of use. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figures 1-5 As shown, this utility model provides a technical solution: a raisin drying rack, including a base plate 1, with brackets 2 fixed on both sides of the top of the base plate 1. Two connecting rods 3 are slidably connected inside the brackets 2, and a shelf 4 is fixed to one end of each connecting rod 3. A tray 5 is provided inside the shelf 4, and a fixing block 6 is fixed to the front end of the tray 5. A housing 7 is provided at the front end of the shelf 4, and a knob 8 is threadedly connected inside the housing 7. A limit block 9 is fixed to one end of the knob 8 inside the housing 7. A movable plate 10 is slidably connected inside the housing 7, and an insert plate 11 is fixed to the bottom of the movable plate 10. A slot 12 for cooperating with the insert plate 11 is provided on the top of the fixing block 6. Both ends of one side of the tray 10 are fixed with a first spring 13. The other end of the first spring 13 is fixed to the inside of the housing 7. By turning the knob 8, the limiting block 9 fixed to it is rotated, causing it to move away from the moving plate 10. At this time, the moving plate 10 will be subjected to the rebound force of the first spring 13 and move upward, causing the insert plate 11 to disengage from the inside of the slot 12, releasing the fixation of the fixing block 6. Then, the user can easily pull the handle to pull the tray 5 out of the shelf 4, which makes it easy to clean and avoids fruit residue or sugar residue remaining on the corners of the tray 5, reducing the risk of mold growth. The above structure is simple to operate, requires no special tools, and the tray 5 can be replaced separately without overall maintenance, reducing the cost of use.

[0022] Reference Figure 3 As shown in this embodiment: the limiting block 9 is elliptical in shape, and the difference between the maximum diameter and the minimum diameter of the limiting block 9 is greater than the distance that the insert plate 11 is inserted into the slot 12. Due to the elliptical shape of the limiting block 9, the difference between its maximum diameter and the minimum diameter allows the moving plate 10 to move a distance that can completely remove the insert plate 11 from the inside of the slot 12, thus avoiding jamming.

[0023] Reference Figure 3 As shown in this embodiment: guide rods 14 are fixed on both sides inside the housing 7, and grooves 15 that cooperate with the guide rods 14 are opened at both ends of the moving plate 10. Through the structure of the guide rods 14 and the grooves 15, the movement trajectory of the moving plate 10 can be restricted to prevent it from deviating during movement.

[0024] Reference Figure 3 As shown in this embodiment: a gasket 16 is provided on the surface of the knob 8. The gasket 16 is made of rubber. Due to the rubber material of the gasket 16, the firmness between the knob 8 and the housing 7 can be further improved, and loosening can be avoided.

[0025] Reference Figures 4-5 As shown in this embodiment: a slide rod 17 is slidably connected to one end of the connecting rod 3, and a horizontal plate 18 is fixed to the other end of the slide rod 17. Insert rods 19 are fixed to both ends of one side of the horizontal plate 18. A plurality of insertion holes 20 for use with the insertion rods 19 are opened on one side of the bracket 2. A second spring 23 is fixed inside the connecting rod 3, and the other end of the second spring 23 is fixed to the slide rod 17. By pulling the horizontal plate 18, the insertion rods 19 are disengaged from the insertion holes 20, and the spacing of the shelf 4 can be adjusted up and down to accommodate different grape thicknesses and ensure air circulation.

[0026] Reference Figure 5 As shown in this embodiment: both sides of the connecting rod 3 are provided with sliding grooves 22, and both sides of the sliding rod 17 are fixed with sliders 21 that cooperate with the sliding grooves 22. Through the structure of the sliding grooves 22 and the sliders 21, it is possible to prevent the user from pulling the horizontal plate 18 with excessive force and pulling the sliding rod 17 out of the interior of the connecting rod 3.

[0027] Working principle: By turning knob 8, the user rotates the fixed limiting block 9, causing it to move away from the moving plate 10. The moving plate 10 then experiences the rebound force of the first spring 13, moving upwards and disengaging the insert plate 11 from the slot 12, releasing the fixing block 6. The user can then easily pull the handle to remove the tray 5 from the shelf 4, facilitating cleaning and preventing fruit residue or sugar residue from remaining on the edges of the tray 5, thus reducing the risk of mold growth. This structure is simple to operate, requires no special tools, and allows for individual replacement of the tray 5 without overall maintenance, reducing operating costs. The elliptical shape of the limiting block 9, with its maximum and minimum diameters, determines the movement distance of the moving plate 10. The structure of the guide rod 14 and groove 15 can completely remove the insert plate 11 from the inside of the slot 12, avoiding jamming. The movement trajectory of the moving plate 10 can be restricted by the structure of the guide rod 14 and groove 15, preventing it from deviating during movement. The rubber material of the gasket 16 can further improve the firmness between the knob 8 and the housing 7, preventing loosening. By pulling the horizontal plate 18 to move the insert rod 19 out of the insert hole 20, the spacing of the shelf 4 can be adjusted up and down to adapt to different grape thicknesses and ensure air circulation. The structure of the slide groove 22 and slider 21 can prevent the user from pulling the horizontal plate 18 with excessive force and pulling the slide rod 17 out of the inside of the connecting rod 3.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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 of the technical features.
