Description

Technical Field

[0001] The utility model relates to the technical field of cold chain logistics, and in particular to a cold chain logistics trolley with dry partitions. Background Art

[0002] Cold chain logistics generally refers to a systematic process that ensures refrigerated and frozen foods are kept in a specified low-temperature environment throughout their production, storage, transportation, sales, and consumption to ensure food quality and reduce food loss. Established with advances in science and technology and the development of refrigeration technology, it is a low-temperature logistics process based on freezing technology and leveraging refrigeration techniques.

[0003] Existing cold chain logistics trolleys are generally equipped with multiple temperature zones. In order to save vehicle energy consumption, after the insulated trolley is pushed into the cabinet, the temperature pipes corresponding to each zone will be directly connected to the interfaces of the corresponding zones, so as to use the pipes to transmit the airflow to achieve different preservation or refrigeration effects. However, since the traditional connection method between pipes and interfaces is usually through threads, long-term use may cause thread wear, resulting in gas leakage and affecting the circulation effect of the cold air.

[0004] Based on this, the utility model designs a cold chain logistics trolley with dry partitions to solve the above problems. Utility Model Content

[0025] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] In some embodiments, please refer to the appendix of the specification. Figure 1-4 A dry partitioned cold chain logistics trolley comprises: a box body 1, with pipes 3 provided on both sides of the box body 1; two connecting components 2 are provided, and the two connecting components 2 are respectively provided on both sides of the box body 1; a partition is provided in the box body 1, which divides the box body 1 into two upper and lower parts, each of which has a different temperature. The pipe 3 is a transmission pipe 3 for guiding gas in the space of each part. After the personnel pushes the cold chain logistics trolley into the cabinet, gas needs to be injected into the box body 1 to preserve and refrigerate the materials in different areas of the box body 1;

[0028] In the embodiment of the present utility model, the connection assembly 2 includes a sleeve shell 201 connected to the surface of the box body 1, a connector 202 is inserted into the sleeve shell 201, and the connector 202 is connected to the pipe 3. A guide hole 204 is opened on the surface of the sleeve shell 201, and a slider 211 is fixedly connected to the outer surface of the connector 202. The surface of the slider 211 contacts the inner wall of the guide hole 204;

[0029] When connecting the pipe 3 to the box body 1, first align the joint 202 of the pipe 3 with the sleeve shell 201 so that the slider 211 on the outer surface of the joint 202 corresponds to the opening of the guide hole 204, and then insert it into the guide hole 204. When inserting, the joint 202 first contacts the spring 206. When the slider 211 moves to a position parallel to the hook-shaped guide hole 204, the slider 211 is screwed to the other end of the parallel part of the guide hole 204 and the joint 202 is loosened. The spring 206 will rebound the joint 202. At this time, the slider 211 on the outer surface of the joint 202 will move to the bent hole position of the hook-shaped guide hole 204. At this time, the extension tube 203 of the joint 202 will also be inserted into the interior of the sleeve shell 201 and sealed by the sealing ring 209. The pipe 3 can then inject gas into the box body 1 to preserve or refrigerate the materials. When it needs to be removed, just reverse the above-mentioned operation.

[0030] In some embodiments, as Figure 2 、 Figure 3 and Figure 4 As shown, as a preferred embodiment of the present invention, the connection assembly 2 further includes a support ring 210, which is fixedly connected to the inner middle portion of the sleeve shell 201. A spring 206 is fixedly connected above the support ring 210, and the upper end of the spring 206 contacts the sleeve shell 201. The support ring 210 is located in the inner middle portion of the sleeve shell 201 and can limit the insertion position of the connector 202, and also limit the retraction distance of the spring 206.

[0031] In the embodiment of the present invention, an extension tube 203 is fixedly connected to the connector 202. The extension tube 203 passes through the middle of the spring 206 and extends below the support ring 210. The extension tube 203 serves as the main gas transmission pipeline and is inserted into the lower part of the socket shell 201 to ensure effective gas transmission.

[0032] In the embodiment of the present invention, a slide groove 205 is formed on the inner wall of the sleeve shell 201, and a slide seat 207 is slidably connected to the slide groove 205. The end of the slide seat 207 close to the spring 206 is fixedly connected to the spring 206; when the connector 202 is inserted into the sleeve shell 201, the connector 202 will squeeze the spring 206. When the spring 206 contracts, the slide seat 207 will vertically limit the spring 206 in the slide groove 205, thereby limiting the contraction distance of the spring 206;

[0033] In the embodiment of the present invention, a sealing ring 209 is fixedly connected to the inner bottom of the sleeve shell 201, and the middle portion of the sealing ring 209 contacts the extension tube 203. The sealing ring 209 is located in the sleeve shell 201, and its inner diameter fits the outer surface of the extension tube 203. When the extension tube 203 transmits gas, it can effectively seal the single gas flow pipeline to prevent gas leakage.

[0034] In the embodiment of the present invention, a ball 208 is provided in the sleeve shell 201, and the surface of the ball 208 contacts the outer surface of the connector 202; the ball 208 is located in the sleeve shell 201 and can guide the connector 202 when the connector 202 is inserted into the sleeve shell 201, thereby ensuring smooth insertion of the connector 202;

[0035] In the embodiment of the present invention, the inner diameter of the sleeve shell 201 is consistent with the outer diameter of the connector 202, and the outer diameter of the extension tube 203 is the same as the inner diameter of the sealing ring 209;

[0036] In the embodiment of the present invention, two guide holes 204 are provided. The guide holes 204 are designed in a curved hook shape and are arranged opposite to each other. The curved hook-shaped guide holes 204 can guide and limit the advancing movement of the elbow when the connector 202 is inserted. At the same time, the curved hook-shaped running track can also prevent the connector 202 from falling off by itself.

[0037] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention.
