Description

Technical Field

[0001] The utility model relates to the technical field of freezers, in particular to a fresh food freezer. Background Art

[0002] Fresh food refers to primary products that have not been cooked or processed, and are only kept fresh and simply arranged for sale, as well as bread, cooked food and other processed products. Fresh products have basically the same characteristics and storage conditions. They need to be kept fresh, refrigerated or frozen. They are bulk products and need to be sold by weight and barcode. They have a relatively short shelf life.

[0003] Existing fresh food freezers are generally large in size and are mostly used in canteens and restaurants to store a variety of fresh frozen foods. They are generally equipped with moving wheels at the bottom to facilitate people's movement. However, the moving structure at the bottom makes it unstable when people place the freezer. At the same time, the single-access method of opening the side door or the top door makes it inconvenient for people to take and put fresh food. Therefore, it is urgent to design a fresh food freezer to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a fresh food freezer to solve the above-mentioned deficiencies in the prior art.

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] like Figure 1-3 As shown, a fresh food freezer provided by the embodiment of the utility model comprises a freezer body 1, a lifting mechanism 8 is fixedly installed below the freezer body 1, the lifting mechanism 8 comprises a forward and reverse motor 11 fixed on the outer wall of the bottom of the freezer body 1, and a transmission shaft 12 is arranged on both sides of the bottom of the freezer body 1 through a bearing seat 13, and the outer side of the transmission shaft 12 is provided with threaded parts 14 distributed at equal distances, and a screw nut 15 is threadedly sleeved on the threaded part 14 outside the transmission shaft 12, and the screw nut 15 is screwed on the screw nut 15. A rotating pin 16 is fixedly provided on the outer wall of the side, and a connecting rod 17 is rotatably installed on the rotating pin 16, a hinge 18 is provided on the end of the connecting rod 17 away from the rotating pin 16, and one end of the connecting rod 17 is connected to a lifting rod 19 through the hinge 18, the outer sliding sleeve of the lifting rod 19 is connected to a guide sleeve 20 fixed to the bottom of the freezer body 1, a base 21 is welded on the outer wall of the bottom end of the lifting rod 19, and synchronous wheels 22 are installed on the two transmission shafts 12, and the two synchronous wheels 22 are electrically connected to a synchronous belt 23.

[0022] Specifically, in this embodiment, a freezer body 1 is included, and a lifting mechanism 8 is fixedly installed below the freezer body 1. The lifting mechanism 8 is adopted to facilitate the stable placement of the freezer on the ground. The lifting mechanism 8 includes a forward and reverse motor 11 fixed on the outer wall of the bottom of the freezer body 1, and a transmission shaft 12 is provided on both sides of the bottom of the freezer body 1 through a bearing seat 13, and the outer side of the transmission shaft 12 is provided with threaded portions 14 distributed at equal distances, and a screw nut 15 is threadedly sleeved on the threaded portion 14 outside the transmission shaft 12. A rotating pin 16 is fixedly provided on the outer wall of one side of the screw nut 15, and a connecting rod 17 is rotatably installed on the rotating pin 16, a hinge 18 is provided on one end of the connecting rod 17 away from the rotating pin 16, and one end of the connecting rod 17 is connected to a lifting rod 19 through the hinge 18, the outer sliding sleeve of the lifting rod 19 is connected to a guide sleeve 20 fixed to the bottom of the freezer body 1, a base 21 is welded on the outer wall of the bottom end of the lifting rod 19, and synchronous wheels 22 are installed on the two transmission shafts 12, and the two synchronous wheels 22 are electrically connected to a synchronous belt 23;

[0023] After people move the freezer to a suitable position, the operator starts the forward and reverse motor 11, so that the forward and reverse motor 11 drives the transmission shaft 12 to rotate. At the same time, the synchronous wheel 22 and the synchronous belt 23 used between the two transmission shafts 12 can make the two transmission shafts 12 rotate synchronously. The synchronous belt 23 can adopt a toothed structure and can transmit a larger torque. As the transmission shaft 12 rotates, the lead screw nut 15 is driven to move outside the transmission shaft 12, so that the connecting rod 17 rotates, so that the connecting rod 17 drives the lifting rod 19 to move downward inside the guide sleeve 20, so that the base 21 contacts the ground. As the transmission shaft continues to rotate, the lifting rod 19 continues to descend, thereby lifting the freezer upward, so that the moving wheel 2 is separated from the ground, and the base 21 is used to achieve the function of stabilizing the support of the freezer. At the same time, in order to better place the reversal of the transmission shaft 12, a brake structure (not shown) can be set on the outside of the transmission shaft 12, thereby further improving the stability of the freezer when it is placed.

[0024] The utility model provides a fresh food freezer, which, through a lifting mechanism 8 arranged at the bottom of the freezer, enables the freezer to be flexibly moved on the ground through the moving wheels 2. At the same time, after moving to a specified position, the moving wheels 2 can be lifted away from the ground through the movement of the lifting mechanism 8, and the freezer is supported by the base 21, thereby ensuring the stability of the freezer when it is placed.

[0025] As an embodiment provided by the utility model, a plurality of moving wheels 2 are fixedly mounted on the outer wall at the bottom of the freezer body 1, and the lifting mechanism 8 is hidden above the moving wheels 2. The moving wheels 2 can improve the flexibility of the freezer and facilitate people to move the freezer.

[0026] As another embodiment provided by the utility model, an upper cover 3 is provided on the outer wall of the top of the freezer body 1, and a side door 4 with a double-opening structure is provided on the front of the freezer body 1, and hinges 7 are provided between the upper cover 3 and the side door 4 and the freezer body 1, and the side door 4 and the upper cover 3 can be flexibly opened and closed by the hinges 7; a handle 10 is fixed to the outer wall of the front of the upper cover 3 by bolts, and an embedded hand groove 9 is provided on the outer wall of the side door 4, and the embedded hand groove 9 facilitates people to open the side door 4, thereby ensuring the aesthetics of the freezer.

[0027] As another embodiment provided by the utility model, an equipment box 5 is provided at one end of the freezer body 1, and components such as refrigeration equipment and a compressor can be installed inside the equipment box 5.

[0028] As another embodiment provided by the utility model, a convex rib plate is fixedly provided on the inner wall of the freezer body 1, and a partition plate 6 is placed on the convex rib plate. The partition plate 6 is used so that people can take and put layered fresh food when opening the side door 4, while ensuring the effect of reducing squeezing between the upper and lower layers of fresh food.

[0029] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
