Description

Technical Field

[0001] This utility model relates to the field of supermarket self-service machine technology, specifically to a tray for supermarket self-service machines. Background Technology

[0002] Supermarket self-service machines (such as self-checkout counters and weighing equipment) are important equipment in modern retail scenarios, and the structural design of their accompanying trays directly affects the ease of use, maintenance costs, and service life of the equipment.

[0003] Currently, self-service machine trays on the market are attempting to use lightweight materials such as plastic. However, plastic trays require screw holes to be drilled through the bottom during installation. These holes can damage the overall mechanical structure of the tray. When bearing heavy objects, the edges of the holes become stress concentration points (especially since plastic materials have low tensile strength), which can easily lead to localized plastic deformation or even cracking. Utility Model Content

[0004] In view of this, the present invention provides a tray for supermarket self-service machines. Through the design of non-through connection holes combined with bottom reinforcing ribs, the weight of the items will not be applied to the connection hole, effectively dispersing the stress concentration phenomenon when the tray is under force, preventing the tray surface from deforming due to stress concentration, thereby improving the strength of the tray.

[0005] To solve the above-mentioned technical problems, this utility model provides a tray for a supermarket self-service machine, including a tray mounted on a bracket by screws. The bottom of the tray has protruding reinforcing ribs, which can improve the strength of the tray. Multiple non-through connection holes are opened on the reinforcing ribs. The non-through connection holes on the bottom of the tray improve the strength of the tray. Connecting parts for threaded engagement with screws are provided in the connecting holes. The bracket and the reinforcing ribs are connected by screws and connecting parts. After the bracket and the tray are aligned, the screws can be turned to install the machine, reducing the need to remove nuts and positioning screws and improving installation efficiency.

[0006] Multiple connecting holes are arranged in a linear array along the length of the reinforcing rib surface, thereby adapting to brackets of different specifications through the linearly arranged multiple connecting holes, improving equipment adaptability, and the spacing between each connecting hole is the same, which can make the force distribution more uniform.

[0007] The connector includes a metal nut that is fixedly installed in the connection hole. The nut is pre-embedded in the connection hole, and the metal nut and the tray are integrally formed to further improve the strength of the tray. When installing the tray, the screw is threaded into the nut after passing through the insertion hole of the bracket.

[0008] The reinforcing ribs include extension strips and reinforcing bars fixed to the bottom of the pallet. The protruding extension strips at the bottom of the pallet can improve the overall support strength of the pallet. Connection holes are opened on the extension strips, and the surface of the reinforcing bars has through holes that match the connection holes. When installing the pallet, the workers attach the reinforcing bars to the bottom of the pallet and then insert screws through the through holes in the extension strips and into the nuts in the connection holes to fix the pallet and the reinforcing bars together, thus completing the installation of the reinforcing bars. Through the design of the reinforcing bars and extension strips, the overall strength of the pallet can be improved.

[0009] The number of reinforcing ribs must be at least two. When processing the pallet, the number of connecting holes can be determined according to the number of reinforcing ribs, so that both reinforcing ribs can be installed on the bottom of the pallet to improve the strength of the pallet.

[0010] The reinforcing ribs are long strips and are set along the length or width of the bottom of the pallet. When it is necessary to lay them along the width, the length of the reinforcing ribs can be increased, and longer reinforcing ribs can be used to cover the bottom of the pallet, thereby increasing the strength of the pallet with fewer reinforcing ribs. Similarly, the reinforcing ribs can be laid flat along the length of the bottom of the pallet, so that multiple reinforcing ribs are laid parallel to the bottom of the pallet along the length.

[0011] The reinforcing ribs have a hollow design, which can further reduce the weight of the tray.

[0012] The preferred material for the reinforcing ribs is aluminum alloy. Aluminum alloy is lighter, which makes the aluminum alloy support components easier to handle and install, effectively reducing labor intensity and construction difficulty. It also has a greater load-bearing capacity and better durability and reliability.

[0013] Both the pallet and the extension strip are made of plastic, which reduces the overall weight of the pallet, making it easier to handle and install.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0015] 1. Improve structural strength and load-bearing capacity: The non-through connection hole design combined with bottom reinforcing ribs effectively disperses stress concentration when the pallet is under stress, avoids deformation caused by local yielding of plastic materials, and significantly improves the load-bearing capacity and service life of the pallet.

[0016] 2. Optimized installation convenience and adaptability: The linear arrangement of connection holes, combined with the pre-embedded nut design, simplifies the bracket installation process and eliminates the need for additional positioning nuts; the multi-hole layout supports flexible adaptation to different bracket specifications, improving equipment compatibility.

[0017] 3. Combination of lightweight and high durability: The reinforced ribs and hollow structure design made of aluminum alloy significantly reduce the overall weight while ensuring support strength, taking into account both convenient handling and long-term fatigue resistance, and reducing maintenance costs.

[0018] 4. Modular structure design: The separate design of the extension strip and the reinforcing rib supports quick disassembly and assembly, which is convenient for later maintenance or partial replacement. At the same time, the combination of plastic tray and metal connectors optimizes the balance between material cost and performance. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0027] Example 1:

[0028] A type of tray for supermarket self-service machines, 200, such as Figure 1 , Figure 2 and Figure 3As shown: a tray 200 is mounted on a bracket 100. The bottom of the tray 200 is provided with reinforcing ribs. Since the tray 200 is mostly of a corrugated structure, the reinforcing ribs protruding from the bottom of the tray 200 can improve the strength of the tray 200. Multiple non-through connection holes 201 are provided on the reinforcing ribs. By providing non-through connection holes 201 on the bottom of the tray 200, when items are placed on the tray 200, the weight of the items will not be applied to the location of the connection holes 201, preventing the surface of the tray 200 from deforming due to stress concentration, thereby improving the strength of the tray 200.

[0029] A connector for threaded engagement with a screw is provided inside the connection hole 201. The bracket 100 and the reinforcing rib are connected to the connector by the screw thread engagement. The tray 200 is placed on the bracket 100. Similarly, the bracket 100 has a through hole corresponding to the position of the connection hole 201 of the tray 200. After the operator inserts the screw into the through hole and the connection hole 201 in sequence, the screw is rotated to fix it to the connector in the connection hole 201, thereby completing the installation of the tray 200. Compared with the existing through-hole connection hole 201, the installation can be completed by simply aligning the bracket 100 and the tray 200 and turning the screw, which reduces the need to remove the nut and positioning screw and improves the installation efficiency.

[0030] Specifically, multiple connecting holes 201 are arranged in a linear array along the length of the reinforcing rib surface, thereby adapting to brackets 100 of different specifications through the linearly arranged multiple connecting holes 201, improving equipment adaptability, and the spacing between each connecting hole 201 is the same, which can make the force distribution more uniform.

[0031] Specifically, the connector includes a metal nut that is fixedly installed in the connection hole 201. The nut is pre-embedded in the connection hole 201, and the nut and the tray 200 are integrally formed, making the nut and the tray 200 inseparable. When installing the tray 200, the screw is threaded into the nut after passing through the insertion hole of the bracket 100, so as to complete the installation of the tray 200.

[0032] The strength of the pallet 200 can be further improved by using a one-piece molded fit between the metal nut and the pallet 200.

[0033] according to Figure 2As shown, the reinforcing rib includes an extension strip 202 fixed to the bottom of the tray 200 and a reinforcing rib 300. The protruding extension strip 202 at the bottom of the tray 200 can be used to improve the overall support strength of the tray 200. A connecting hole 201 is opened on the extension strip 202, and a through hole adapted to the connecting hole 201 is opened on the surface of the reinforcing rib 300. When the bracket 100 is fixed to the extension strip 202 by screws, the screws can pass through the reinforcing rib 300 and be inserted into the nut. When the operator installs the tray 200, the reinforcing rib 300 can be fitted to the tray. The bottom surface of the tray 200 is fixed together with the reinforcing rib 300 by passing screws through the holes of the extension strip 202 and inserting the screws into the nuts of the connecting holes 201. Then, the tray 200 together with the fixed reinforcing rib 300 is placed on the bracket 100. After passing the remaining screws through the insertion holes of the bracket 100 and the through holes of the reinforcing rib 300, they are inserted into the nuts of the connecting holes 201 to complete the installation of the reinforcing rib 300. The design of the reinforcing rib 300 and the extension strip 202 can improve the overall strength of the tray 200.

[0034] Specifically, there are two reinforcing ribs 300. When processing the pallet 200, the number of connecting holes 201 can be determined according to the number of reinforcing ribs 300, so that both reinforcing ribs 300 can be installed on the bottom of the pallet 200 to improve the strength of the pallet 200.

[0035] Specifically, the reinforcing rib 300 is long and narrow, and is set along the length or width of the bottom of the pallet 200. When it is necessary to lay it along the width, the length of the reinforcing rib 300 can be increased. Two reinforcing ribs 300 can be used to cover the bottom of the pallet 200, and a smaller number of reinforcing ribs 300 can be used to increase the strength of the pallet 200.

[0036] Similarly, the reinforcing ribs 300 can be laid flat along the length of the bottom of the tray 200, so that multiple reinforcing ribs 300 are laid parallel to the bottom surface of the tray 200 along the length.

[0037] Specifically, the reinforcing rib 300 has a hollow design, which can further reduce the weight of the tray 200.

[0038] Specifically, the preferred material for the reinforcing rib 300 is aluminum alloy. Aluminum alloy is lighter, which makes the aluminum alloy support more convenient to handle and install, effectively reducing labor intensity and construction difficulty. It also has a greater load-bearing capacity and better durability and reliability.

[0039] Specifically, both the pallet 200 and the extension strip 202 are made of plastic. The plastic material can reduce the overall weight of the pallet 200, making it easier to handle and install.

[0040] Example 2;

[0041] The difference from Embodiment 1 is that, in this embodiment, the reinforcing rib 300 is fixed inside the tray 200, so that the reinforcing rib 300 and the tray 200 are integrally formed.

[0042] Specifically, the reinforcing rib 300 has a threaded hole, and the bracket 100 is connected to the threaded hole of the reinforcing rib 300 by screws. By fixing the reinforcing rib 300 to the bottom of the tray 200, the connecting hole 201 in Embodiment 1 does not need to be opened inside the tray 200, and the nut does not need to be set. By opening the threaded hole in the reinforcing rib 300, when the tray 200 needs to be installed, the tray 200 is placed on the bracket 100. At this time, the reinforcing rib 300 embedded in the tray 200 fits against the surface of the bracket 100, so that the threaded hole on the surface of the reinforcing rib 300 and the insertion hole on the bracket 100 are aligned on the same axis. After the screw passes through the insertion hole of the bracket 100, it is threaded into the threaded hole of the reinforcing rib 300, thereby completing the installation of the bracket 100 and the tray 200.

[0043] Compared with Embodiment 1, the pre-embedded reinforcing rib 300 in Embodiment 2 can reduce the installation steps. When installing the tray 200, it is not necessary to first connect the reinforcing rib 300 to the tray 200 and then to the bracket 100. In Embodiment 2, the tray 200 can be fixed by directly connecting the reinforcing rib 300 to the bracket 100, thus reducing the installation steps.

[0044] Similarly, in comparison with Embodiment 2, the detachable nature of the reinforcing rib 300 in Embodiment 1 makes the tray 200 more flexible to assemble and disassemble, the operation and installation methods more flexible, and the reinforcing rib 300 and tray 200 easier to inspect and maintain.

[0045] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
