Description

Technical Field

[0001] The utility model relates to the technical field of cable protection pipes, and particularly relates to a cable protection pipe which is convenient to replace. Background Technique

[0002] A cable protection sleeve is a pipe used to protect electric wires and cables. It is usually made of plastic, metal or composite materials. It can provide physical protection to prevent the cable from being damaged by external objects, sharp items or other factors. At the same time, it can also play roles such as insulation, corrosion resistance and high temperature resistance.

[0003] There are different types of cable protection sleeves according to different usage environments. Among them, there is an XJHT line insulation protection sleeve. The XJHT insulation protection sleeve is formed by using high-performance insulation materials, and can perform insulation restoration or protection strengthening treatment on the hidden trouble part of the line, effectively preventing the insulation layer of the wire from being damaged due to external environmental changes (such as tree branch friction, extreme temperature, chemical substances, etc.), thereby reducing the risk of electric leakage and short circuit.

[0004] The existing XJHT line insulation protection sleeve is composed of an upper cover, a lower cover, a terminal head and an intermediate connector component. The upper cover and the lower cover are mutually clamped and combined into a protection pipe for protecting the cable. When installing the upper cover and the lower cover, it is necessary to first place the lower cover on the cable line, and keep the lower cover balanced with one hand, and insert the upper cover from below the cable with the other hand to form the combination. During this process, both hands support the lower cover and the upper cover respectively, and the upper cover needs to be kept in a stable horizontal state to be inserted into the lower cover. However, during high-altitude operation, this operation is extremely inconvenient. Based on this, a cable protection pipe which is convenient to replace is provided. Content of the Utility Model

[0005] The purpose of the utility model is to provide a cable protection pipe which is convenient to replace in order to solve the problems in the above background.

[0008] The lower cover assembly includes an arc-shaped lower cover and an arc-shaped docking groove;

[0009] The arc-shaped lower cover is sleeved on the outer side of the bottom of the cable and clamped between the arc-shaped outer shell and the arc-shaped inner shell, which is used to wrap and protect the cable.

[0010] The arc-shaped docking groove is formed at the position where the arc-shaped lower cover contacts the elastic limiting arc piece, which is used to prevent interference between the arc-shaped lower cover and the elastic limiting arc piece during insertion.

[0011] As a further solution of the present invention: One end of the notch part of the arc-shaped lower cover is fixedly connected with an arc-shaped hanging piece. The arc-shaped lower cover is hung on the outer side of the cable through the arc-shaped hanging piece, so as to achieve the horizontal balance maintenance of the arc-shaped lower cover.

[0012] As a further solution of the present invention: A receiving groove is formed at one end of the connecting piece. The inner diameter of the arc-shaped hanging piece is larger than the outer diameter of the arc-shaped inner shell. The receiving groove is used to provide a receiving space for the arc-shaped hanging piece.

[0013] As a further solution of the present invention: Two receiving grooves are symmetrically formed along the long side direction of the connecting piece. The height of the receiving groove is greater than the thickness of the arc-shaped hanging piece. The horizontal length of the receiving groove matches the horizontal length of the arc-shaped hanging piece.

[0014] As a further solution of the present invention: Clamping convex edges are formed on the inner sides of both ends of the arc-shaped outer shell and the outer sides of both ends of the arc-shaped inner shell. Strip-shaped clamping grooves for clamping the clamping convex edges are formed on the inner and outer sides of the arc-shaped lower cover.

[0015] As a further solution of the present invention: The arc-shaped outer shell, the connecting piece, the arc-shaped inner shell, and the clamping convex edges are integrally formed by an extrusion molding process. The elastic limiting arc piece is welded and fixed to the arc-shaped inner shell by an ultrasonic welding process. The receiving groove is formed by cutting;

[0016] The arc-shaped lower cover, the strip-shaped clamping groove, and the arc-shaped docking groove are integrally formed by an extrusion molding process. The arc-shaped hanging piece is welded and fixed to the arc-shaped lower cover by an ultrasonic welding process.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] By setting the elastic limiting arc piece, the preliminary limit connection between the upper cover assembly and the cable can be realized, so that there is no need to support the upper cover assembly. Then, through the arc-shaped hanging piece, the hanging operation between the arc-shaped lower cover and the cable can be carried out.

[0026] The connecting piece 102 is fixed inside the arc - shaped outer shell 101, the arc - shaped inner shell 103 is fixed inside the connecting piece 102, the elastic limiting arc piece 105 is fixed at one end of the bottom of the arc - shaped inner shell 103, and two elastic limiting arc pieces 105 are symmetrically arranged along the long - side direction of the arc - shaped inner shell 103. The arc - shaped inner shell 103 is clamped outside the cable 3 through the elastic limiting arc piece 105 to achieve the preliminary limiting connection with the cable 3;

[0027] The lower cover assembly 2 includes an arc - shaped lower cover 201 and an arc - shaped docking groove 203;

[0028] The arc-shaped lower cover 201 is sleeved on the outer side of the bottom of the cable 3 and clamped between the arc-shaped outer shell 101 and the arc-shaped inner shell 103 to realize the wrapping and protection of the cable 3;

[0029] The arc-shaped docking groove 203 is formed at the position where the arc-shaped lower cover 201 contacts the elastic limiting arc piece 105 to prevent interference between the arc-shaped lower cover 201 and the elastic limiting arc piece 105 during insertion;

[0030] One end of the notch part of the arc-shaped lower cover 201 is fixedly connected with an arc-shaped hanging piece 204. The arc-shaped lower cover 201 is hung on the outer side of the cable 3 through the arc-shaped hanging piece 204 to achieve the horizontal balance maintenance of the arc-shaped lower cover 201;

[0031] A storage groove 106 is formed at one end of the connecting piece 102. The inner diameter of the arc-shaped hanging piece 204 is larger than the outer diameter of the arc-shaped inner shell 103, and the storage groove 106 is used to provide a storage space for the arc-shaped hanging piece 204;

[0032] Clamping convex edges 104 are formed on the inner sides of both ends of the arc-shaped outer shell 101 and the outer sides of both ends of the arc-shaped inner shell 103, and strip-shaped clamping grooves 202 for clamping the clamping convex edges 104 are formed on the inner and outer sides of the arc-shaped lower cover 201.

[0033] In this embodiment: When this protection tube is in use, its installation operation is as follows:

[0034] First, the upper cover assembly 1 is sleeved on the outer side of the cable 3 through the arc-shaped inner shell 103 and the elastic limiting arc piece 105. The elastic limiting arc piece 105 can be deformed and opened under the action of an external extrusion force, so as to be conveniently sleeved on the outer side of the cable 3. After that, the elastic limiting arc piece 105 will reset under the action of its own elastic force, thus realizing the preliminary limit between the upper cover assembly 1 and the cable 3. At this time, when the support for the upper cover assembly 1 is released, the upper cover assembly 1 can also maintain a stable sleeved state;

[0035] Then, take the lower cover assembly 1 and hang it on the outer side of the cable 3 through the arc-shaped hanging piece 204. Then, hold one end of the arc-shaped lower cover 201 and push the end where the arc-shaped hanging piece 204 is located to a distance (at this time, the whole lower cover assembly 2 is in an inclined state). The arc-shaped hanging piece 204 slides along the outer wall of the cable 3 and stops when there is a gap space between one end of the arc-shaped lower cover 201 and one end of the upper cover assembly 1. Then, lift one end of the arc-shaped lower cover 201 upward to align it with the lower cover assembly 1. The arc-shaped hanging piece 204 can provide a suspension force for the other end of the arc-shaped lower cover 201, thereby reducing the working intensity of the staff;

[0036] When one end of the arc-shaped lower cover 201 is aligned with the middle area between the arc-shaped outer shell 101 and the arc-shaped inner shell 103, the arc-shaped lower cover 201 can be inserted into the middle area between the arc-shaped outer shell 101 and the arc-shaped inner shell 103. At this time, the arc-shaped docking groove 203 is sleeved with the elastic limiting arc piece 105, and the strip-shaped card slot 202 is clamped with the clamping convex edge 104. Among them, the clamping of the strip-shaped card slot 202 and the clamping convex edge 104 can provide vertical limit for the arc-shaped lower cover 201 and the upper cover assembly 1.

[0037] Finally, both ends of the arc-shaped lower cover 201 are flush with both ends of the arc-shaped outer shell 101 and the arc-shaped inner shell 103, and the arc-shaped hanging piece 204 is received inside the receiving groove 106, which will not affect the installation operations of subsequent components such as the middle connector and the terminal head.

[0038] Please refer specifically to Figures 1 to 4 , two receiving grooves 106 are symmetrically arranged along the long side direction of the connecting piece 102, the height of the receiving groove 106 is greater than the thickness of the arc-shaped hanging piece 204, and the horizontal length of the receiving groove 106 matches the horizontal length of the arc-shaped hanging piece 204.

[0039] In this embodiment: through the structural setting of the two symmetric receiving grooves 106, when installing the upper cover assembly 1, there is no need to consider the front and back directions, and the installation operation is more convenient;

[0040] By making the height of the receiving groove 106 greater than the thickness of the arc-shaped hanging piece 204, the arc-shaped hanging piece 204 can better enter the inside of the receiving groove 106;

[0041] By making the horizontal length of the receiving groove 106 match the horizontal length of the arc-shaped hanging piece 204, the two ends of the arc-shaped lower cover 201 can be flush with the two ends of the arc-shaped outer shell 101 and the arc-shaped inner shell 103.

[0042] Please refer specifically to Figures 1 to 4 , the arc-shaped outer shell 101, the connecting piece 102, the arc-shaped inner shell 103, and the clamping convex edge 104 are integrally formed by an extrusion molding process, the elastic limiting arc piece 105 is welded and fixed to the arc-shaped inner shell 103 by an ultrasonic welding process, and the receiving groove 106 is formed by cutting;

[0043] The arc-shaped lower cover 201, the strip-shaped card slot 202, and the arc-shaped docking groove 203 are integrally formed by an extrusion molding process, and the arc-shaped hanging piece 204 is welded and fixed to the arc-shaped lower cover 201 by an ultrasonic welding process.

[0044] In this embodiment: through the above processes, the convenient processing and production of the upper cover assembly 1 and the lower cover assembly 2 can be realized, and the processing can be improved on the basis of the existing processes, which is convenient for popularization.

[0045] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
