Description

Technical Field

[0001] The utility model relates to the technical field of transportation accessory design, in particular to a rubber sleeve for transporting new energy lithium batteries. Background Art

[0002] A lithium-ion battery pack is a battery pack consisting of multiple lithium-ion battery cells connected in series and parallel, and equipped with a circuit protection system. Lithium-ion battery packs are widely used in electronic devices such as electric vehicles, electric bicycles, laptops, and mobile phones.

[0003] Most existing transport devices for lithium battery packs use roller conveyors for transportation, such as the utility model patent with publication number CN210972594U, named "A Spring-Boosted Conveyor Roller", which includes a conveyor and several rollers installed inside it. A pair of front pillars are connected to the bottom of the front end of the conveyor, and a pair of rear pillars are connected to the bottom of the rear end of the conveyor. Iron chains are also provided on the bottom surfaces of the front and rear ends of the conveyor. Hanging rods are welded to the bottom surfaces of the front and rear ends of the conveyor, a cross bar is welded between the bottoms of the two front pillars, and a hook is welded at the center of the outer side of the cross bar, which is engaged with the iron chain.

[0004] When the above-mentioned conveyor transports pallets containing lithium battery packs, the rollers directly contact the pallets for transportation, which will cause wear on the outer surface of the rollers and generate metal powder. This will not only reduce the service life of the rollers, but if the generated metal powder enters the battery pack, it may also cause short circuits or poor contact between battery cells, thereby reducing the overall performance and service life of the battery pack. In addition, the rollers themselves are not insulated, which leads to certain safety hazards during transportation. Utility Model Content

[0005] In response to the deficiencies in the prior art, the utility model provides a rubber sleeve for transporting new energy lithium batteries, which is used to solve the technical problem raised in the background technology that the existing rollers will wear out when they directly contact the pallet, resulting in a reduced service life of the rollers.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A rubber sleeve for transporting new energy lithium batteries includes an upper sleeve and a lower sleeve, both of which are semi-arc-shaped with the same radius, and the upper sleeve and the lower sleeve are spliced ​​together to form a tube, and the upper sleeve and the lower sleeve are detachably connected; a positioning piece, which is located between the upper sleeve and the lower sleeve and is used to prevent displacement when the upper sleeve and the lower sleeve are connected.

[0008] Working principle:

[0009] This device is a rubber sleeve for transporting new energy lithium batteries. It is mainly used to be installed on rollers and transported synchronously with the rotation of the rollers.

[0010] During installation, first install the upper sleeve and the lower sleeve on both sides of the roller respectively, and then use the positioning pieces between the upper sleeve and the lower sleeve to splice the upper sleeve and the lower sleeve. After the splicing is completed, the roller is sleeved in the upper sleeve and the lower sleeve. At this time, by fixing the upper sleeve and the lower sleeve, the rubber sleeve formed by the upper sleeve and the lower sleeve can rotate synchronously with the rotation of the roller.

[0011] Beneficial effects obtained:

[0012] First, by setting the upper sleeve and the lower sleeve to be semi-arc-shaped, the corresponding roller can be effectively mounted inside by splicing the upper sleeve and the lower sleeve. Because the upper sleeve and the lower sleeve are spliced ​​into a tubular shape, it is ensured that the objects placed thereon can be effectively transported during rotation.

[0013] Secondly, a positioning piece is provided, which can effectively prevent the upper and lower casings from being out of position when the upper and lower casings are assembled, thereby making it easier to connect the upper and lower casings. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and embodiments.

[0022] Example 1:

[0023] Reference Figures 1 to 4 The present application is a rubber sleeve for transporting new energy lithium batteries, comprising an upper sleeve 1 and a lower sleeve 2. Both the upper sleeve 1 and the lower sleeve 2 are injection molded from POK material. Both the upper sleeve 1 and the lower sleeve 2 are semi-arc-shaped with the same radius, and the upper sleeve 1 and the lower sleeve 2 are combined to form a tube. The side walls of the upper sleeve 1 and the lower sleeve 2 are provided with patterns 13 for increasing friction. This arrangement can effectively increase the friction during transportation of objects through the patterns 13, and stably transport objects. The inner sides of the upper sleeve 1 and the lower sleeve 2 are provided with a well-shaped hollow space 10, which can reduce the amount of material used and reduce production costs while meeting the strength requirements of the rubber sleeve. The inner side of the upper sleeve 1 is provided with a pin 12 for connecting to the roller steel pipe. The provided pin 12 can further prevent the rubber sleeve from sliding on the roller, making it more stable and reliable during transportation.

[0024] like Figure 2 and Figure 3 As shown, a plurality of first connecting holes 3 are provided on the side wall of the upper casing 1, and a plurality of second connecting holes 4 corresponding to the first connecting holes 3 are provided on the lower casing 2. The upper casing 1 and the lower casing 2 are fixedly connected by respectively installing screws and nuts in the corresponding first connecting holes 3 and second connecting holes 4.

[0025] like Figure 4 As shown, expansion joints 11 are formed at the connection points on both sides of the upper casing 1 and the lower casing 2 after being assembled. After the upper casing 1 and the lower casing 2 are connected by screws and nuts, the expansion joints 11 will shrink, so that the upper casing 1 and the lower casing 2 can be firmly installed on the surface of the roller steel pipe.

[0026] like Figure 2 and Figure 3 As shown, a positioning member is provided between the upper casing 1 and the lower casing 2. The positioning member is a plurality of protrusions 5. The plurality of protrusions 5 are fixedly provided at the end of the upper casing 1 facing the lower casing 2. The end of the lower casing 2 facing the upper casing 1 is respectively provided with a plurality of grooves 6 corresponding one to one with the protrusions 5. The plurality of protrusions 5 slide into the corresponding grooves 6. This arrangement can effectively complete the splicing between the upper casing 1 and the lower casing 2 by extending the plurality of protrusions 5 into the corresponding grooves 6, thereby preventing the upper casing 1 and the lower casing 2 from slipping when connected.

[0027] Example 2:

[0028] The difference between Example 2 and Example 1 is that: Figure 5 and Figure 6 As shown, the positioning member is an elastic rubber ring 9, a semi-arc-shaped first connecting groove 7 is provided on the side wall of the upper sleeve 1, and a semi-arc-shaped second connecting groove 8 is provided on the side wall of the lower sleeve 2. The first connecting groove 7 and the second connecting groove 8 correspond to each other and are connected at both ends. The rubber ring 9 is sleeved in the first connecting groove 7 and the second connecting groove 8. This arrangement can effectively achieve positioning between the upper sleeve 1 and the lower sleeve 2 by sleeved in the first connecting groove 7 and the second connection corresponding to the first connecting groove 7 when the upper sleeve 1 and the lower sleeve 2 are connected and fixed. The radius of the rubber ring 9 is slightly smaller than that of the upper sleeve 1 and the lower sleeve 2, but the thickness of the rubber ring 9 is slightly greater than the groove depth of the first connecting groove 7 and the second connecting groove 8. In this way, not only can the upper sleeve 1 and the lower sleeve 2 be effectively positioned, but also the friction between the rubber sleeve and the object can be increased when the rubber sleeve rotates.

[0029] Working principle:

[0030] During installation, first install the upper sleeve 1 and the lower sleeve 2 on both sides of the roller respectively, align the pin 12 in the upper sleeve 1 with the hole on the roller steel pipe and insert it, then splice the lower sleeve 2 and the end of the upper sleeve 1 through the positioning piece, further pass the external screws through the first connecting hole 3 and the second connecting hole 4 in sequence, and match and fix them with the external nuts, so that the upper sleeve 1 and the lower sleeve 2 are fixedly mounted on the roller steel pipe, and rotate and transport synchronously with the rotation of the steel pipe.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
