Description

Technical Field

[0001] The utility model relates to the technical field of cold storage shelves, in particular to a cold storage shelf with an anti-dumping function. Background Art

[0002] Cold storage racks are storage racks used in cold storage. Their function is to make full use of the cold storage space and improve storage efficiency. There are many types of cold storage racks, including common drive-through racks, shuttle racks, push-back racks and other intensive storage racks. Drive-through racks are one of the types of storage racks commonly used in large and medium-sized cold storage rooms. They can make the most of the precious cold storage space. However, the existing cold storage racks are prone to tipping over after carrying heavier objects, which can lead to danger.

[0003] In order to address the above problems, the Chinese patent with the existing announcement number CN214307828U proposes a cold storage shelf with an anti-dumping function. The device compresses the spring to move into the positioning groove after the positioning block is subjected to force, and then pulls the extension column out of the extension groove until the positioning block moves to the bottom of the extension hole and is stuck in the extension hole, thereby fixing the position of the extension column in the extension groove. At this time, the extension block is attached to the ground, increasing the contact range of the front and rear sides of the base plate with the ground, thereby improving the anti-dumping ability of the shelf, and when the shelf is in a state to be assembled, the anti-dumping mechanism is stored in the base plate for easy transportation.

[0004] However, although the above-mentioned cold storage shelf with anti-dumping function can improve the anti-dumping ability of the shelf by pulling out the extension column from the extension groove, so that the positioning block is stuck in the extension hole and the position of the extension column in the extension groove is fixed, the cold storage shelf with anti-dumping function requires taking out and fixing the four extension columns from the extension grooves in turn, and this process requires a lot of time and physical strength, thereby reducing the efficiency of installing the anti-dumping function of the cold storage shelf. Therefore, the utility model provides a cold storage shelf with anti-dumping function to meet the demand. Utility Model Content

[0036] like Figures 1 to 8 As shown, an embodiment of the utility model provides a cold storage shelf with an anti-dumping function, including a base 2, a shelf body 1 is provided on the top of which, at least two stabilizing plates 3 are symmetrically provided in the base 2, the stabilizing plates 3 are rotatably connected to the base 2 through a second rotating shaft 7, a through groove 4 for the stabilizing plates 3 to rotate is provided in the base 2, a turntable 6 is provided at the axial position of the base 2 which is rotatable through a third rotating shaft 10, a driving component 5 for driving the turntable 6 to rotate is provided on the base 2, and a connecting rod 8 is provided, which is equal to the stabilizing plate 3, and the two ends of the connecting rod 8 are respectively hinged to the turntable 6 and the stabilizing plate 3, so that the driving component 5 drives the turntable 6 to rotate, and drives the stabilizing plate 3 to rotate through the connecting rod 8.

[0037] Specifically, by installing the shelf body 1 on the base 2, and then driving the turntable 6 to rotate through the driving component 5, the turntable 6 pulls the connecting rod 8 to move, so that the connecting rod 8 drives the stabilizing plate 3 to rotate along the base 2 and expand along the base 2, thereby increasing the supporting area of ​​the base 2. The device can simultaneously drive multiple stabilizing plates 3 to rotate at the same time to improve the anti-dumping effect of the shelf body 1, save the physical strength and time of the users, and improve the installation efficiency of the anti-dumping function of the cold storage shelf, and solve the problem that the existing cold storage shelf needs to take out and fix the four extension columns from the extension groove one by one, and this process requires a lot of time and physical strength, thereby reducing the installation efficiency of the anti-dumping function of the cold storage shelf.

[0038] It should be noted that the driving assembly 5 can be a structure such as a three-phase motor, a reduction motor, etc. that can drive the turntable 6 to rotate. At the same time, the interior of the base 2 is a hollow structure, and the through groove 4 is connected to the hollow structure inside the base 2; further, in this embodiment, the number of stabilizing plates 3 is four, and correspondingly, the number of connecting rods 8 is also four, and the connecting rods 8 are equidistantly distributed at the positions of the turntable 6.

[0039] like Figure 3As shown, in this embodiment, the driving assembly 5 includes a rotating shaft 53, which is rotatably arranged on the base 2, and the upper and lower ends of the rotating shaft 53 are respectively sleeved with a worm wheel 54 and a first gear 51, a supporting block 55 is fixedly connected to the base 2, and a worm 57 meshing with the worm wheel 54 is rotatably connected to the supporting block 55, a control rod 56 fixedly connected to the worm 57, and a second gear 52 is fixedly connected to the turntable 6, and the second gear 52 meshes with the first gear 51. The control rod 56 is a Z-shaped structure, and the diameter of the first gear 51 is larger than the diameter of the second gear 52. Specifically, the control rod 56 drives the worm 57 to rotate, the worm 57 drives the worm wheel 54 to rotate, the worm wheel 54 drives the rotating shaft 53 to rotate, the rotating shaft 53 drives the first gear 51 to rotate, the first gear 51 drives the second gear 52 to rotate, and the second gear 52 drives the turntable 6 to rotate. The overall operation is simple, and the worm wheel 54 and the worm 57 are used to achieve a self-locking effect on the turntable 6 to prevent the turntable 6 and the stabilizing plate 3 from loosening. At the same time, since the first gear 51 is larger than the second gear 52, the rotation efficiency of the turntable 6 can also be improved and the physical strength of the user can be saved.

[0040] like Figure 3 and Figure 5 As shown, in this embodiment, the distance from one end of the stabilizing plate 3 hinged to the connecting rod 8 to the second rotating shaft 7 is smaller than the distance from the other end of the stabilizing plate 3 to the second rotating shaft 7 .

[0041] like Figure 7 and Figure 8 As shown, in this embodiment, a plurality of pulley 91 assemblies 9 are provided at the bottom of the stabilizing plate 3, and the pulley 91 assembly 9 includes a movable plate 95, which is slidably arranged inside the stabilizing plate 3, and a movable groove 94 for the movable plate 95 to slide is provided inside the stabilizing plate 3. The bottom of the movable plate 95 is rotatably connected to a movable rod 92, and the bottom of the movable rod 92 is rotatably connected to a pulley 91, and a spring 93 is fixedly connected to one end of the movable plate 95 away from the movable rod 92. An embedding groove 11 for the pulley 91 to be embedded is provided through the bottom of the stabilizing plate 3, and the movable rod 92 is movable. The movable plate 95 is movably arranged between the embedded groove 11 and the movable groove 94. Specifically, when the stabilizing plate 3 rotates along the through groove 4, the spring 93 will push the movable rod 92 to drive the pulley 91 to move out along the embedded groove 11 and fit the ground, so that the stabilizing plate 3 can have a support point with the ground, thereby improving the stability of the stabilizing plate 3. Similarly, when the pulley 91 is retracted into the through groove 4, the pulley 91 will move into the embedded groove 11. At this time, the movable plate 95 squeezes the spring 93, so that the pulley 91 fits with the base 2, reducing the friction between the stabilizing plate 3 and the base 2.

[0042] Working principle:

[0043] By installing the shelf body 1 on the base 2, and then driving the worm 57 to rotate through the control rod 56, the worm 57 drives the worm wheel 54 to rotate, the worm wheel 54 drives the rotating shaft 53 to rotate, the rotating shaft 53 drives the first gear 51 to rotate, the first gear 51 drives the second gear 52 to rotate, the second gear 52 drives the turntable 6 to rotate, and the turntable 6 pulls the connecting rod 8 to move, so that the connecting rod 8 drives the stabilizing plate 3 to rotate along the base 2 and expand along the base 2, thereby increasing the supporting area of ​​the base 2. The device can simultaneously drive multiple stabilizing plates 3 to rotate at the same time to improve the anti-dumping effect of the shelf body 1, save the physical strength and time of the user, and improve the installation efficiency of the anti-dumping function of the cold storage shelf, and solves the problem that the existing cold storage shelf needs to take out and fix the four extension columns from the extension groove in turn, and this process requires a lot of time and physical strength, thereby reducing the installation efficiency of the anti-dumping function of the cold storage shelf.
