Description

Technical Field

[0001] The utility model belongs to the field of sleeves, relates to combined sleeve technology, and particularly relates to a single-layer snap-fit protective sleeve. Background Art

[0002] When circuits are arranged in some scenarios, sleeves are fixed on the surface to protect wires, improve safety, facilitate maintenance and replacement, keep the appearance neat and tidy, and achieve other specific functions.

[0003] Most of the existing sleeves used for circuits are snap-fit types. One type forms a ring that fits the circuit through the sliding combination between two arc blocks; the other type has a structure that can be fitted at both ends of a cuboid, and a ring that fits the circuit is formed through the connection of the structures. However, both of the above two snap-fit sleeves have limitations: for the snap-in type sleeve, the snap-in structure is generally located outside the formed ring. During use, it is generally cut according to the length of the circuit. When sleeving a long-distance circuit, it is difficult to complete quickly, and due to its outwardly protruding snap-in structure, it is difficult to fix different sections of the sleeve; while for the sliding split type sleeve, a large space is required during installation to completely slide the sleeve to a flush fit. Generally, this type of sleeve will have a through groove opened inside, and the position of the sleeve and the circuit is fixed by clamping an external structure through the through groove. However, the opened through groove will affect the stress distribution and wear mechanism inside the sleeve, thereby affecting the applicable circuit use environment of the sleeve.

[0004] Therefore, the utility model proposes a single-layer snap-fit protective sleeve. Content of the Utility Model

[0006] To achieve the above object, according to an embodiment of the first aspect of the utility model, a single-layer snap-fit protective sleeve is proposed, including: a plurality of half sleeves, a circuit is placed between two of the half sleeves, and a combination mechanism is arranged between the half sleeves, and the combination mechanism includes:

One end of each of several elastic rods is fixedly connected with a conical block. Connecting grooves are formed on the surface of the half sleeve. The conical block and the connecting groove are adapted to each other;

[0009] A limiting component for restricting the position of the half sleeve is provided between the half sleeve and the circuit.

[0010] Optionally, the side of the protruding block close to the half sleeve is arc-shaped, and the center point of the arc is located on the extension line of the half sleeve. The side of the protruding block away from the half sleeve is horizontal.

[0026] Next, the technical solution of the present utility model will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present utility model.

[0027] As Figures 1-6 shown, a single-layer snap-fit protective sleeve includes a plurality of half sleeves 1. The half sleeves 1 are soft and elastic, and a circuit is placed between two half sleeves 1. A combination mechanism is provided between the half sleeves 1, and the combination mechanism includes:

[0028] A forming assembly, arranged on the surface of the half sleeve 1, includes a protruding block 21 fixed on the half sleeve 1 close to the circuit side. The protruding block 21 is elastic. The other end of the half sleeve 1 is fixedly connected with a C-shaped block 22. The opening of the C-shaped block 22 faces away from the half sleeve 1, and the protruding block 21 and the C-shaped block 22 are adapted;

[0029] The connecting component is arranged between two half sleeves 1 on the horizontal surface of the circuit. It includes a large connecting column 23 and a small connecting column 24. Both the large connecting column 23 and the small connecting column 24 are arc-shaped. The radian of the large connecting column 23 is greater than that of the small connecting column 24, and both ends of them are semi-circular, with the centers of the circles located inside the large connecting column 23 and the small connecting column 24. The large connecting column 23 and the small connecting column 24 are attached to the half sleeve 1. A plurality of elastic rods 25 are fixedly connected to the surfaces of the large connecting column 23 and the small connecting column 24 close to the half sleeve 1. The two elastic rods 25 are symmetric about the normal line of the midline on the large connecting column 23 and the small connecting column 24. One end of each of several elastic rods 25 is fixedly connected with a conical block 26. Connecting grooves 27 are formed on the surfaces of the half sleeve 1. The conical block 26 and the connecting groove 27 are adapted to each other;

[0030] A limiting component for restricting the position of the half sleeve 1 is arranged between the half sleeve 1 and the circuit;

[0031] In the actual application process of this single-layer snap-on protective sleeve, protrusion blocks 21 and C-shaped blocks 22 with different shapes are respectively arranged at both ends of the half sleeve 1, and the protrusion block 21 and the C-shaped block 22 are adapted to each other. Thus, the protrusion blocks 21 and the C-shaped blocks 22 on the surfaces of the two half sleeves 1 can be clamped to form a ring, and the circuit is arranged inside the ring for protection. The formation of the ring is realized by the clamping of the two half sleeves 1. During the installation and forming process, it should be noted that the structural positions that can be clamped correspond to each other, and the requirement for the operating space is relatively low. Moreover, a limited number of connecting grooves 27 are formed on the surface of the half sleeve 1. Through the clamping of the connecting groove 27 with the elastic rod 25 and the conical block 26, the positions of the half sleeve 1 and the large connecting column 23 and the small connecting column 24 can be restricted. At this time, according to the environmental requirements of the circuit laying, half sleeves 1 with different connecting lengths can be placed at different positions, and the circuits in multiple scenarios can be protected more comprehensively;

[0032] In some specific implementation schemes, the side of the protrusion block 21 close to the half sleeve 1 is arc-shaped, and the center point of the arc is located on the extension line of the half sleeve 1. The side of the protrusion block 21 away from the half sleeve 1 is horizontal. The half sleeve 1 has elasticity; a half column 31 is fixedly connected to the horizontal side surface of the protrusion block 21, and the half column 31 is located on the side of the protrusion block 21 close to the extension line of the half sleeve 1; a protruding shaft 32 is fixedly connected to the inside of the C-shaped block 22 facing the opening, and the protruding shaft 32 and the half column 31 are adapted to each other;

[0033] In some specific embodiments, the above-mentioned limiting component includes a fitting block 41 and a clamping block 42. The fitting block 41 contacts one end of the half sleeve 1. An arc-shaped groove 43 is formed on the surface of the fitting block 41, and the surface of the arc-shaped groove 43 is attached to the circuit. A through groove 44 is formed inside the fitting block 41. A triangular block 45 is fixedly connected to the side of the arc-shaped groove 43 away from the circuit, and the vertex of the triangular block 45 faces the surface of the circuit. A plurality of limiting teeth 46 are fixedly connected to the side of the clamping block 42 away from the circuit, and the plurality of limiting teeth 46 are evenly fixed on the surface of the clamping block 42. The limiting teeth 46 and the triangular block 45 are adapted to each other;

[0034] The working principle of the present utility model is as follows: First, the protruding block 21 of one half sleeve 1 is aligned with the C-shaped block 22 of the other half sleeve 1, and the protruding block 21 is pressed into the inside of the C-shaped block 22. Then, the circuit is placed in the space above the protruding block 21 on the half sleeve 1, and the C-shaped blocks 22 and the protruding blocks 21 at the other ends of the two are correspondingly clamped. At this time, the two half sleeves 1 form a ring to surround the circuit. Then, according to the usage scenario of the circuit, half sleeves 1 of different lengths or the same length are assembled into a ring, and the formed ring of half sleeves 1 is pulled closer so that the connection grooves 27 on the surface of the half sleeves 1 are located on the same straight line. At this time, the positions of the large connecting column 23 and the small connecting column 24 can be fixed to the surface of the half sleeve 1 according to the positions of the tapered blocks 26 corresponding to the connection grooves 27. At this time, the positions of the half sleeves 1 forming different rings are fixed. After the length of the sleeve is appropriate, a fitting block 41 is placed on the surface of the circuit at one end of the half sleeve 1 in a fitting manner, and the clamping block 42 is inserted corresponding to the position of the through groove 44 on the surface of the fitting block 41. After the surface of the clamping block 42 is attached to the circuit, the clamping block 42 is released. The limiting teeth 46 on the surface of the clamping block 42 contact the triangular block 45, restricting the positions of the clamping block 42 and the fitting block 41. The same operation is performed to fix the fitting block 41 and the clamping block 42 at the other end of the sleeve.

[0035] The above embodiments are only used to illustrate the technical method of the present utility model and not to limit it. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the present utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the present utility model.
