Description

Technical Field

[0001] The utility model belongs to the technical field of automatic cold storage, in particular to an automatic cold storage which is easy to move. Background Art

[0002] Cold storage refers to the use of artificial means to create an environment with a different temperature or humidity from the outdoor environment. It is also a constant temperature and humidity storage equipment for food, liquids, chemicals, medicines, vaccines, scientific experiments and other items. Compared with refrigerators, it has a larger refrigeration area and is an important infrastructure in daily production and life.

[0003] Publication No. "CN217383445U" discloses "an automated refrigerated cold storage". By fixing the refrigerated cold storage body in the slot, since the insulation base is provided with insulation foam and rock wool layers, the lower end of the refrigerated cold storage body can be insulated to prevent the hot ground from affecting the refrigeration effect of the refrigerated cold storage body. Since a support plate is provided in the slot, the refrigerated cold storage body can be supported to prevent the insulation foam and rock wool layer from being damaged due to the excessive weight of the refrigerated cold storage body, thereby increasing the service life. At the same time, by providing a groove on the left door, the convex plate can be extended into the groove when the left door and the right door are in contact and closed, so that a number of No. 1 convex blocks and No. 2 convex blocks are staggered and fitted together, thereby avoiding gaps between the left door and the right door and preventing the loss of cold air.

[0004] The above technical solution still has the following disadvantages during use:

[0005] There is a lack of corresponding moving mechanism, and the bottom of the cold storage is supported only by supporting feet, resulting in a fixed position of the cold storage. During use, due to the heavy overall weight of the cold storage, it is inconvenient to move the cold storage, which increases the labor intensity when moving the cold storage and has poor flexibility.

[0006] To solve the above problems, we propose an automated cold storage that is easy to move. Utility Model Content

During use, due to the large overall weight of the cold storage, it is inconvenient to move the cold storage, which increases the labor intensity when moving the cold storage and the disadvantage of poor flexibility.

[0027] The support legs 3 provide support for the bottom of the cold storage body 1 , and the cold storage body 1 is kept away from the ground in combination with the heat-insulating base 2 , thereby ensuring the use effect of the cold storage body 1 . Meanwhile, the rollers 5 facilitate the movement of the cold storage body 1 .

[0028] The adjustment assembly includes a fixed rod 14, a movable block 15, a connecting arm 16, a screw rod 17, an extrusion plate 18 and a driving mechanism. A plurality of slide grooves 13 are provided at the bottom of the insulation base 2, and the slide grooves 13 are arranged on one side of the supporting leg 3. The fixed rod 14 is fixed inside the slide groove 13. The movable block 15 is slidably sleeved on the fixed rod 14, and the connecting arm 16 is hinged between one side of the movable block 15 and the outer wall of the sleeve 7. Two vertical plates are relatively fixed at the bottom of the insulation base 2. The screw rod 17 is arranged between the two vertical plates. The two extrusion plates 18 are both threadedly arranged on the screw rod 17. The extrusion plate 18 cooperates with the movable block 15. Through the threaded cooperation between the extrusion plate 18 and the screw rod 17, it is convenient to adjust the two extrusion plates 18 away from each other. Combined with the extrusion plate 18 and the movable block 1 5, and the sliding cooperation between the movable block 15 and the fixed rod 14, thereby squeezing the movable block 15 in the direction of the supporting leg 3. Under the hinged action at both ends of the connecting arm 16, and the active cooperation between the movable ring 6 and the supporting leg 3, the sleeve 7 is squeezed downward along the direction of the supporting leg 3 until the rubber pad 8 is driven to move down and contact with the ground, thereby increasing the friction between the insulation base 2 and the ground, limiting the roller 5, and at the same time, with the downward movement of the sleeve 7, the movable ring 6 is driven to squeeze the limit plate 12 downward.

The support rod 21 passes through the extrusion plate 18, and the extrusion plate 18 and the support rod 21 are slidably matched. Through the sliding match between the extrusion plate 18 and the support rod 21, the extrusion plate 18 is effectively limited and guided, thereby ensuring the stability of the extrusion plate 18 moving forward and backward.

[0031] A number of traction blocks 22 are fixed on both sides of the top of the insulation base 2, and a number of telescopic rods 24 are connected between the upper surface of the rubber pad 8 and the insulation base 2. A return spring is arranged inside the telescopic rod 24. The telescopic rod 24 effectively limits and guides the rubber pad 8, thereby ensuring the stability of the up and down movement of the sleeve 7 and the rubber pad 8.

[0032] A moving assembly 25 is fixedly connected to the upper front end of the cold storage body 1 , a left door 26 is movably connected to the left lower end of the moving assembly 25 , and a right door 27 is movably connected to the right lower end of the moving assembly 25 .

[0033] Example:

[0034] During the use of the cold storage, in the initial state, the two extrusion plates 18 are in a state of being away from each other, at this time, the sleeve 7 and the limit plate 12 are both at the bottom, the extrusion spring 11 is in a compressed state, and the rubber pad 8 is in contact with the ground, and the brake pad 10 is against the roller 5;

[0035] When the cold storage body 1 needs to move, the servo motor 23 is started to drive the active bevel gear 19 to rotate. Under the meshing action of the active bevel gear 19 and the driven bevel gear 20, the screw rod 17 is driven to rotate. Under the threaded cooperation of the extrusion plate 18 and the screw rod 17, combined with the sliding cooperation of the extrusion plate 18 and the support rod 21, the two extrusion plates 18 are driven to stably approach each other. Under the hinged action at both ends of the connecting arm 16, combined with the action of the telescopic rod 24 and its internal return spring, the sleeve 7 is driven to move upward, and then the rubber pad 8 is driven upward away from the ground. Under the elastic action of the extrusion spring 11, the piston rod 9 is driven to return to the initial position upward, and then the brake pad 10 is driven upward away from the roller 5, and the servo motor 23 stops running;

[0036] At this time, only the roller 5 is in contact with the ground, and under the action of the traction block 22, the cold storage body 1 is pulled to move;

[0037] After the cold storage body 1 is moved to a suitable position, when it needs to be fixed, the servo motor 23 is driven to rotate in the opposite direction. Under the joint action of the active bevel gear 19, the driven bevel gear 20 and the screw 17, the two extrusion plates 18 are driven to move away from each other. With the movement of the extrusion plates 18, the movable block 15 is squeezed in the direction of the support leg 3 in combination with the sliding cooperation between the movable block 15 and the fixed rod 14. In combination with the hinged action at both ends of the connecting arm 16 and the active cooperation between the movable ring 6 and the support leg 3, the sleeve 7 is squeezed downward along the direction of the support leg 3 until the rubber pad 8 is driven to move down to contact the ground, thereby increasing the friction between the insulation base 2 and the ground and limiting the roller 5.

[0038] At the same time, as the sleeve 7 moves downward, the movable ring 6 is driven to squeeze the limit plate 12 downward. The limit plate 12 moves downward, compresses the extrusion spring 11, and drives the piston rod 9 to move downward, thereby driving the brake pad 10 downward until it contacts the roller 5, further limiting the roller 5 and ensuring the stability of the cold storage body 1.

[0039] Compared with the prior art, the utility model drives the cold storage body 1 to move through the roller 5 and the traction block 22. At the same time, under the joint action of the adjustment component and the driving mechanism, the adjustment sleeve 7 moves downward until the rubber pad 8 contacts the ground, and under the joint action of the movable ring 6, the limit plate 12, the piston rod 9 and the extrusion spring 11, the brake pad 10 is driven to move downward until it is against the roller 5, and the roller 5 is limited and fixed to ensure the stability of the cold storage body 1. This solves the problem of the lack of corresponding moving mechanism in the prior art. The bottom of the cold storage is only supported by the supporting feet, resulting in the position of the cold storage being fixed. During use, due to the large overall weight of the cold storage, it is inconvenient to move the cold storage, which increases the labor intensity when moving the cold storage and the disadvantage of poor flexibility.

[0040] It should be further explained that the installation structure, connection method or setting method of each component in the utility model are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented. At the same time, the servo motor 23 in the utility model is purchased on the market, and those skilled in the art can install and use it according to the requirements;
