[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model provides a technical solution: a cargo placement rack for a cold storage that is convenient for entry and exit, comprising a driving frame 1, a side frame 2, a slide 3 and a shelf assembly 4, the shelf assembly 4 is located between the driving frame 1 and the side frame 2, and the shelf assembly 4 passes through the slide 3, the driving frame 1 is built with a worm 11 and a worm wheel 12, the worm wheel 12 is fixedly connected to one end of a driving shaft 13, a gear 131 is provided on the driving shaft 13, the driving shaft 13 passes through the slide 3, and is connected to the slide 3 through a bearing, the other end of the driving shaft 13 is connected to the side frame 2 through a bearing, the gear 131 is located inside the slide 3, the shelf assembly 4 comprises a tooth plate 41 and a cargo placement rack 42, the tooth plate 41 slides through the slide 3, and the gear 131 is meshed with the tooth plate 41 for transmission, and when the gear 131 rotates, it can drive the tooth plate 41 to move.

[0025] The slide seat 3 includes a slide groove, a slide rail 411 is fixedly provided on the tooth plate 41, and the slide rail 411 of the tooth plate 41 is slidably connected to the slide groove of the slide seat 3. The tooth plate 41 can slide along the slide groove of the slide seat 3 under the drive of external force.

[0026] Among them, the worm 11 and the worm wheel 12 constitute a transmission structure. When the worm 11 is driven to rotate by the hand wheel 14, the worm 11 drives the worm wheel 12 to rotate, and the worm wheel 12 drives the driving shaft 13 fixed thereto to rotate, and the driving shaft 13 drives the gear 131 on its upper portion to rotate. When the gear 131 rotates, the tooth plate 41 of the shelf assembly 4 is driven to move horizontally along the slide groove of the slide seat 3 through the meshing transmission between the teeth. When the tooth plate 41 moves horizontally, it drives the cargo placement rack 42 to move horizontally synchronously, so as to adjust the horizontal position of the cargo placement rack 42 and move the cargo placement rack 42 forward at a deep position, so as to facilitate the placement and pickup of the goods and facilitate the entry and exit of the goods.

[0027] The worm 11 and the worm wheel 12 are meshed and driven, and the worm 11 and the worm wheel 12 constitute a worm 11-worm wheel 12 structure, and the worm 11-worm wheel 12 structure has a certain self-locking property, that is, the worm 11 can drive the worm wheel 12 to rotate, but the worm wheel 12 cannot reversely drive the worm 11;

[0028] During the process of manually adjusting the position of the shelf assembly 4, the self-locking property of the worm 11 and the worm wheel 12 structure enables the shelf assembly 4 to remain fixed in a certain position, thereby improving the stability of the shelf assembly 4 during the adjustment process, and further facilitating the placement and entry and exit of goods.

[0029] Among them, one end of the worm 11 is fixedly connected to the handwheel 14, and the handwheel 14 is located outside the driving stand 1. The operation method is to manually drive the handwheel 14 to rotate, and the handwheel 14 drives the worm 11 to rotate synchronously. The position adjustment of the shelf assembly 4 is controlled by the rotation direction and number of rotations of the handwheel 14. The adjustment method is simple and easy to operate.

[0030] Among them, an avoidance groove 31 is opened on one side of the slide 3, and the structure of the shelf assembly 4 is automatically avoided through the avoidance groove 31 to prevent the slide 3 from causing obstruction during the movement, thereby ensuring the normal horizontal movement of the shelf assembly 4.

[0031] Among them, the cargo display rack 42 is provided with multiple groups of through slots, which can be selectively set. The multiple groups of through slots can reduce the dead weight of the shelf assembly 4. The structure of the cargo display rack 42 can be selected according to the use requirements, and a flat-plate structure or a multi-layer rack structure can be used.

[0032] The bottoms of the driving stand 1 and the side stand 2 are both welded with mounting lugs, and mounting holes are provided on the mounting lugs, so that the mounting lugs facilitate the installation and fixation of the driving stand 1 and the side stand 2.

[0033] The slide 3 is fixed on the outer side of the driving frame 1, and the slide 3 remains stationary.

[0034] Among them, the tooth plate 41 is located on one side of the cargo placement rack 42, and a sliding groove is opened on the inner side of the side frame 2. The other side of the cargo placement rack 42 is embedded in the sliding groove of the side frame 2 and is slidably connected with the side frame 2. When the cargo placement rack 42 moves, one side of it slides along the sliding groove of the slide seat 3, and the other side of it slides along the sliding groove of the side frame 2, thereby improving the stability during the sliding process, thereby improving the stability of the overall shelf structure.

[0035] Working principle: the hand wheel 14 is manually driven to rotate, and the worm 11 is driven to rotate synchronously through the hand wheel 14. The worm 11 drives the worm wheel 12 to rotate, and the worm wheel 12 drives the driving shaft 13 fixed thereto to rotate, and the driving shaft 13 drives the gear 131 on its upper part to rotate. When the gear 131 rotates, the tooth plate 41 of the shelf assembly 4 is driven to move horizontally along the slide groove of the slide seat 3 through the meshing transmission between the teeth, and the other side of the shelf assembly 4 is driven to slide along the slide groove of the side frame 2. When the tooth plate 41 moves horizontally, it drives the cargo placement rack 42 to move horizontally synchronously, so as to adjust the horizontal position of the cargo placement rack 42, and move the deep position of the cargo placement rack 42 forward, so as to facilitate the placement and retrieval of the cargo, and facilitate the entry and exit of the cargo. The position adjustment of the shelf assembly 4 is controlled by the rotation direction and the number of rotations of the hand wheel 14. In the process of manually adjusting the position of the shelf assembly 4, the self-locking property of the worm 11 and worm wheel 12 structure is relied on to enable the shelf assembly 4 to remain fixed in a certain position, thereby ensuring the stability of the shelf assembly 4 during the adjustment process.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
