Description

Technical Field

[0001] The present application relates to the field of cold storage cabinets, and in particular to a weighing cold storage cabinet. Background Art

[0002] Fresh-keeping cabinets are equipment for refrigerating and preserving goods. However, after taking the goods from the fresh-keeping cabinet, the buyer still needs to check out at the salesperson. The salesperson needs to weigh various goods, calculate the price of various goods and the total price of all goods. In order to realize unmanned and automated shopping and improve the shopping experience, fresh-keeping cabinets that can be weighed have been designed. At present, there are finished fresh-keeping cabinets on the market, but the cost is high. The weighing function can be realized by modifying ordinary fresh-keeping cabinets to reduce the equipment cost. The general modification plan is to install a weighing sensor between the shelf and the beam of the fresh-keeping cabinet. However, the position design and connection of the shelf and the beam of the ordinary fresh-keeping cabinet do not consider weighing. The connection position of the two is relatively random, and the beam is not located in the center of the cabinet. In addition, in order to prevent the function of the fresh-keeping cabinet from being damaged, the beam of the fresh-keeping cabinet cannot be changed or added. When the original connection point of the shelf and the beam is directly connected through a weighing sensor and used as a weighing fresh-keeping cabinet, the shelf will shake easily after the customer takes the item, affecting the weighing result and the fairness of the transaction.

[0032] An embodiment of the present application provides a weighing refrigeration cabinet.

[0033] like Figure 1 As shown, a weighing cold storage cabinet includes a cabinet body 1, a plurality of supporting beams 12 and a storage piece 2. A cabinet door 11 is provided on the front of the cabinet body 1 along the height direction of the cabinet body 1, and the direction from the cabinet door 11 to the back of the cabinet body 1 is the depth direction. The supporting beam 12 is fixed in the cabinet body 1, and the length direction of the supporting beam 12 is perpendicular to the depth direction of the cabinet body 1. The supporting beam 12 is located between the center of the depth direction of the cabinet body 1 and the back of the cabinet body 1, that is, the supporting beam 12 is not located at the center of the depth direction of the cabinet body 1, and the length direction of the supporting beam 12 is the width direction of the cabinet body 1. A plurality of the supporting beams 12 are spaced apart and distributed up and down, and a storage piece 2 is installed on each of the supporting beams 12.

[0034] like Figure 1 and Figure 2 As shown, the storage piece 2 is installed on the supporting beam 12 through a single-point weighing sensor 5, one end of the single-point weighing sensor 5 is fixed on the supporting beam 12, the second end of the single-point weighing sensor 5 is fixedly connected to the bottom of the storage piece 2, the second end of the single-point weighing sensor 5 is closer to the cabinet door 11 than the first end, the first end of the single-point weighing sensor 5 corresponds to the center position in the length direction of the supporting beam 12, the center of the bottom of the storage piece 2 and the second end of the single-point weighing sensor 5 are correspondingly arranged, wherein the first end of the single-point weighing sensor 5 is a fixed end, and the second end is a weighing end, that is, the first end is installed on the supporting bottom plate, and the second end is used to place the object to be weighed.

[0035] In the embodiment of the present application, in the process of transforming an ordinary fresh-keeping cabinet into a weighing fresh-keeping cabinet, the position of the supporting beam 12 is not changed, but the position on the storage part 2 for connecting the single-point weighing sensor 5 is changed, so that the position on the storage part 2 for connecting the single-point weighing sensor 5 is located at the bottom center of the storage part 2, which improves the balance of the storage part 2, reduces the shaking of the storage part 2, and improves the accuracy of weighing; and the second end of the single-point weighing sensor 5 extends toward the cabinet door 11 side, so that the second end of the single-point weighing sensor 5 corresponds to the center of the depth direction of the cabinet 1, so that the center of the storage part 2 corresponds to the center of the depth direction of the cabinet 1, and at the same time, the first end and the second end of the single-point weighing sensor 5 both correspond to the center position of the supporting beam 12 in the length direction, so that the center of the storage part 2 corresponds to the center of the width direction of the cabinet 1, so that the storage part 2 can be evenly expanded forward, backward, left and right, so that the storage part 2 fully utilizes the space of the cabinet 1 and ensures the capacity of the storage part 2.

[0036] like Figure 2 , Figure 3 and Figure 4 The storage piece 2 shown is a storage frame with an open top, and the storage frame is a grid structure. A reinforcing plate 3 is fixedly provided at the bottom of the storage frame. The reinforcing plate 3 is provided with a mounting hole for installing a single-point weighing sensor 5, and the mounting hole corresponds to the center of the bottom of the storage frame.

[0037] The storage frame of the grid structure uses less materials and has low cost, but the rigidity of the grid structure is relatively weak. The present application connects the single-point weighing sensor 5 and the storage frame through the reinforcing plate 3 to improve the rigidity of the position where the storage frame contacts the single-point weighing sensor 5. On the first hand, the connection stability between the storage frame and the single-point weighing sensor 5 is improved, and the shaking of the storage frame is reduced; on the second hand, it can avoid that the position where the grid structure connects to the single-point weighing sensor 5 is deformed differently after placing objects of different weights in the storage frame, which affects the weighing result. The second convenience can also be understood as installing a rigid plate at the weighing end of the single-point weighing sensor 5, and then placing the storage frame of the grid structure on the rigid plate. In order to ensure the relative stability of the storage frame of the grid structure and the rigid plate, the two are connected. Among them, the reinforcing plate 3 can be an iron plate or a steel plate, with a thickness of 2-3mm.

[0038] The single-point weighing sensor 5 and the reinforcing plate 3 are fixedly connected by at least two bolts, and the plurality of bolts are spaced apart along the length direction of the supporting crossbeam 12. The bottom of the storage frame includes a plurality of longitudinal strips 21 and a plurality of transverse strips 22 connected to each other, and the longitudinal strips 21 are parallel to the depth direction of the cabinet 1. The length direction of the reinforcing plate 3 is parallel to the length direction of the longitudinal strips 21. The two ends of the reinforcing plate 3 are fixedly connected to the storage frame. The single-point weighing sensor 5 and the reinforcing plate 3 are fixed by bolts spaced apart along the width direction of the cabinet 1, so that the storage frame is fixed at multiple points on the left and right, thereby reducing the left and right shaking of the storage frame. The length direction of the reinforcing plate 3 is designed along the depth direction of the cabinet 1, and the two ends are fixed on the bottom of the storage frame, so that the storage frame is fixed at multiple points in front and behind, thereby reducing the front and back shaking of the storage frame. Among them, front, back, left, and right are the front direction in front of the user when standing at the cabinet door 11 facing the inside of the cabinet, front and back are the depth direction of the cabinet 1, and left and right are the width direction of the cabinet 1.

[0039] The reinforcing plate 3 is in the shape of a long strip, and a strip-shaped mounting plate 31 is fixedly connected to both ends of the reinforcing plate 3. The length direction of the strip-shaped mounting plate 31 is perpendicular to the length direction of the reinforcing plate 3. The mounting plate is installed on the bottom of the storage frame through a strip-shaped fixing frame, and both ends of the strip-shaped mounting plate 31 are fixedly connected to the bottom of the storage frame. The strip-shaped mounting plate 31 provides connection stability between the reinforcing plate 3 and the storage frame, and reduces the shaking of the storage frame relative to the reinforcing plate 3.

[0040] The reinforcing plate 3 is provided with a first rib 32 on the side facing away from the storage frame, and the reinforcing plate 3 is provided with a first rib 32 on both sides along the length direction, and the first rib 32 is perpendicular to the reinforcing plate 3. The first rib 32 further improves the rigidity of the reinforcing plate 3 in the depth direction of the cabinet 1, reduces the deformation and vibration of the reinforcing plate 3 in the depth direction of the cabinet 1, and thus reduces the shaking amplitude of the storage frame in the depth direction of the cabinet 1 after the center of gravity of the storage frame for placing items changes after taking out items. The two strip mounting plates 31 are provided with a second rib 33 on the sides facing away from each other, and the second rib 33 is perpendicular to the strip mounting plates 31. The second rib 33 improves the rigidity of the strip mounting plates 31 in the width direction of the cabinet 1, reduces the deformation and vibration of the strip mounting plates 31 in the width direction of the cabinet 1, and thus reduces the shaking amplitude of the storage frame in the width direction of the cabinet 1 after the center of gravity of the storage frame for placing items changes after taking out items.

[0041] Specifically, the reinforcing plate 3 and the first rib plate 32 are an integrally bent structure. The strip-shaped mounting plate 31 and the second rib plate 33 are an integrally bent structure.

[0042] A downwardly protruding reinforcing rib 23 is provided at the bottom of the longitudinal bar 21 at the bottom of the storage frame. The reinforcing rib 23 extends along the longitudinal bar 21. The reinforcing rib 23 and the longitudinal bar 21 are designed as an integrated whole, thereby improving the rigidity of the longitudinal bar 21 of the storage frame and reducing the deformation and vibration of the longitudinal bar 21 in the depth direction of the cabinet 1, thereby reducing the shaking amplitude of the storage frame in the depth direction of the cabinet 1 after the center of gravity of the storage frame where the items are placed changes after taking out the items.

[0043] like Figure 3 , Figure 4 and Figure 5 As shown, the single-point weighing sensor 5 is installed on the supporting beam 12 through a connecting piece, and the connecting piece includes a U-shaped ferrule 4 with an opening at the bottom and a connecting plate 41. The U-shaped ferrule 4 is used to be sleeved on the outer periphery of the supporting beam 12, and the three side plates of the U-shaped ferrule 4 are provided with top screws. The top screws pass through the side plates of the U-shaped ferrule 4 and press against the outer surface of the supporting beam 12. Each side plate is provided with at least two top screws. The connecting plate 41 and the top surface of the U-shaped ferrule 4 are fixedly connected, and one end of the single-point weighing sensor 5 is installed on the top surface of the connecting plate 41, and the top surface of the connecting plate 41 is horizontally arranged, and the flatness of the upper surface of the connecting plate 41 is less than 0.3mm, thereby improving the installation stability of the single-point weighing sensor 5.

[0044] The present application connects the support beam 12 and the single-point weighing sensor 5 through a connector, so as to avoid the problem that the single-point weighing sensor 5 cannot be stably fixed due to the uneven surface of the beam, improve the stability of the installation of the single-point weighing sensor 5, and improve the accuracy of the measurement of the single-point weighing sensor 5. Specifically, the U-shaped ferrule 4 is stably fixed on the support beam 12 from multiple directions, so that the connecting plate 41 is stably installed on the support beam 12. The multiple top screws on each side plate of the U-shaped ferrule 4 are spaced apart along the length direction of the support beam 12 to avoid the shaking of the U-shaped ferrule 4.

[0045] The inner side of the bottom surface of the storage piece 2 gradually decreases from the edge to the center. As the number of items in the storage piece 2 decreases, when only the last layer of items is left, if the bottom surface of the storage piece 2 is flat or high inside and low outside, the items are unevenly distributed. When the items on one side are taken out, the center of gravity of the shelf changes significantly, causing the storage piece 2 to shake greatly, affecting the accuracy of weighing. The design of the bottom of the storage piece 2 of the present application allows the items to move closer to the center of the storage piece 2 along with the inclined bottom surface, so that the center of gravity of the storage piece 2 containing the items is close to the center of the storage piece 2. When the items are taken out again, the center of gravity of the storage piece 2 changes little, and the storage piece 2 shakes little, thereby improving the accuracy of weighing.

[0046] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
