Description

Technical Field

[0001] This utility model relates to the field of printer technology, and in particular to a rubber roller mating connection structure and printer based on a portable printer. Background Technology

[0002] Currently, portable printers, as small item management label printing machines increasingly used in commercial and home scenarios, place particular emphasis on assembly efficiency during product manufacturing. The structure is typically optimized to reduce the difficulty of installing components, while also considering production costs. For example, existing printer structures include a roller structure and a roller cover. The roller structure comprises a roller body and a roller shaft. Installation involves creating a mounting groove on the roller cover and drilling holes on the side ears of the mounting groove. The roller body is then placed within the mounting groove, and the roller shaft is placed within the round hole. However, to ensure installation stability, the roller body and roller shaft need to be separated, resulting in a complex and inefficient installation method. Summary of the Invention

[0003] To address the problems in the prior art, this application proposes a rubber roller mating connection structure and a printer based on a portable printer.

[0004] To achieve the aforementioned technical objectives, as a first aspect, this utility model proposes a rubber roller mating connection structure based on a portable printer, comprising:

[0005] A rubber roller, the rubber roller comprising a roller body and a rubber roller shaft;

[0006] An elastic ring is sleeved around the outer periphery of the rubber roller shaft;

[0007] A rubber roller cover, wherein an installation groove and a connection groove are provided on the rubber roller cover;

[0008] The roller body is disposed in the mounting groove, and the rubber roller shaft is disposed in the connecting groove; wherein, the diameter of the opening of the connecting groove is smaller than the diameter of the elastic ring, and the diameter of the opening of the connecting groove is larger than the diameter of the rubber roller shaft;

[0009] Preferably, the number of the connecting grooves is one pair, and they are distributed on the opposite side of the rubber roller cover located in the mounting groove;

[0010] The number of the rubber roller shafts is one pair, and they are arranged one-to-one in the pair of connecting grooves;

[0011] Preferably, the roller mating connection structure based on the portable printer further includes a spring;

[0012] One end of the spring abuts against the side wall of the roller body away from the opening of the mounting groove, and the other end of the spring is fixed inside the mounting groove;

[0013] Preferably, the diameter of the connecting groove is 3.4-3.6 mm, and the diameter of the rubber roller is 3.3 mm.

[0014] As a second aspect, this utility model proposes a printer, which includes the rubber roller mating connection structure based on a portable printer as described in any of the preceding claims.

[0015] The beneficial effects of this utility model are reflected in the fact that by opening a connecting groove on the rubber roller cover, the rubber roller shaft can be directly connected to the connecting groove through the open groove, making the installation simple and quick, and improving installation efficiency. Specifically, an elastic ring is set around the outer periphery of the rubber roller shaft body, and the diameter of the connecting groove opening is set to be smaller than the diameter of the elastic ring and larger than the diameter of the body. During installation, the elastic properties of the elastic ring are used to squeeze the rubber roller shaft through the opening of the connecting groove into the connecting groove. The connection method is simple, and the installation of the rubber roller structure and the rubber roller cover body is more stable. Attached Figure Description

[0025] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0026] like Figure 1-4 As shown, as a first aspect, this utility model proposes a rubber roller mating connection structure based on a portable printer, including a rubber roller, an elastic ring 4, and a rubber roller cover.

[0027] The rubber roller includes a roller body 101 and a rubber roller shaft 102; the elastic ring 4 is sleeved on the outer periphery of the rubber roller shaft 102; the rubber roller cover has an installation groove 202 and a connecting groove 201; the roller body 101 is disposed in the installation groove 202, and the rubber roller shaft 102 is disposed in the connecting groove 201; furthermore, the diameter of the opening of the connecting groove 201 is smaller than the diameter of the elastic ring 4, and the diameter of the opening of the connecting groove 201 is larger than the diameter of the rubber roller shaft 102.

[0028] Specifically, by creating a connecting groove 201 on the rubber roller cover 2, the rubber roller shaft 102 can be directly connected to the connecting groove 201 through the open groove. This installation method is simple and quick, improving installation efficiency. Specifically, an elastic ring 4 is provided around the outer periphery of the rubber roller shaft 102, and the diameter of the connecting groove 201 is set to be smaller than the diameter of the elastic ring 4 and larger than the diameter of the body. During installation, the elastic properties of the elastic ring 4 are used to compress the rubber roller shaft 102 through the opening of the connecting groove 201 into the connecting groove 201. This connection method is simple, and the interference fit between the rubber roller shaft 102 and the connecting groove 201 is more stable.

[0029] Furthermore, there is a pair of connecting grooves 201, which are distributed on the opposite side of the rubber roller cover located in the mounting groove 202; there is a pair of rubber roller shafts 102, which are respectively arranged in the pair of connecting grooves 201. The pair of connecting grooves 201 limit the pair of rubber roller shafts 102, making the connection between the rubber roller and the rubber roller cover more stable.

[0030] Furthermore, the diameter of the groove 201 is 3.4-3.6 mm, and the diameter of the rubber roller 1 is 3.3 mm. In this embodiment, the diameter of the groove 201 is preferably 3.4 mm.

[0031] Furthermore, the roller mating connection structure based on the portable printer also includes a spring 3; one end of the spring 3 abuts against the side wall of the roller body 101 away from the groove opening of the mounting groove 202, and the other end of the spring 3 is fixed inside the mounting groove 202. This ensures that after the roller shaft 102 is compressed and displaced within the oblong hole, the roller structure is reset by the spring 3 when the compression force disappears.

[0032] Secondly, this utility model proposes a printer, which includes the rubber roller mating connection structure based on any one of the aforementioned portable printers. This rubber roller structure design based on a portable printer improves the installation efficiency of the rubber roller structure.
