[0002] In order to avoid the risk of accidental electric shock or power supply interruption caused by the pulling, disturbance or damage of electric wires by external factors, especially in areas with a higher severity or a higher risk of installation scenarios, it is stipulated that wire pipes must be provided for electric wires for protection. By fixing the wire pipes on the wire laying path and threading the electric wires through the wire pipes, the situation of accidental electric shock or power supply interruption caused by the disturbance and damage of the electric wires by external factors can be avoided.

[0003] However, most of the existing wire pipes are PVC sleeves or galvanized pipes, which are of fixed sizes and cannot be adjusted appropriately according to the scenario requirements. At the same time, they are prone to being wound messily. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a deformable wire threading sleeve to solve the problems existing in traditional wire pipes, such as fixed sizes, synchronous threading of multiple electric wires, and being prone to being wound messily.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A deformable wire threading sleeve includes an outer sleeve section, a transition sleeve section and an inner rolled sleeve section which are connected in sequence. The outer sleeve section, the transition sleeve section and the inner rolled sleeve section integrally form a sleeve that spirally inwardly rolls up, and a spiral wire groove is formed inside the sleeve. Among them, one side of the outer sleeve section has a hook tooth portion extending towards the spiral axis, and a hook tooth groove cooperating with the hook tooth portion is provided on the outer side surface of the transition sleeve section. When winding up, under the tension of the sleeve, the hook tooth portion and the hook tooth groove form self-locking.

[0007] As a further description of the above technical scheme:

[0008] The concave inner side surface of the transition sleeve section is smoothly connected with the concave inner side surfaces of the outer sleeve section and the inner rolled sleeve section, and the thickness of the transition sleeve section is greater than the thicknesses of the outer sleeve section and the inner rolled sleeve section.

[0009] As a further description of the above technical scheme:

[0010] Under normal conditions, a horizontal wire inlet is formed between one side of the outer sleeve section and the transition sleeve section.

[0011] As a further description of the above technical scheme:

[0012] A plurality of wire grooves are provided along the length direction on the outer spiral surface of the inner rolled sleeve section.

[0013] As a further description of the above technical scheme:

[0014] Positioning holes and positioning pins are respectively provided at both ends of the inner side of the involute pipe section, and the positioning holes and positioning pins between adjacent sleeves are matched.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Embodiment 1

[0032] like Figures 1 - 3 As shown, compared with traditional PVC wire pipes or galvanized pipes, the variable wire threading sleeve proposed by the utility model includes a sleeve 10 and a clamp 20, and the sleeve 10 and the clamp 20 are used in combination, wherein the sleeve 10 is made of conventional PVC material. Specifically, the sleeve 10 includes an outer pipe section 11, a transition pipe section 12 and an inner rolled pipe section 13 that are connected once, and the outer pipe section 11, the transition pipe section 12 and the inner rolled pipe section 13 are integrally formed into a sleeve 10 with one side spirally rolled inward, so that a spiral wire groove B is formed on the inner side of the sleeve 10, and a plurality of wires are passed through the spiral wire groove B without being entangled or messy.

[0033] Further, specifically, a hook tooth portion 111 extending toward the spiral axis is provided on one side of the outer tube section 11, and the hook angle of the hook tooth portion 111 is inclined toward the spiral winding side. At the same time, a hook tooth groove 121 cooperating with the hook tooth portion 111 is provided on the outer side of the transition tube section 12. When winding, the hook tooth portion 111 and the hook tooth groove 121 form a self-locking structure under the tension of the sleeve 10, and the spiral wire groove is closed in the length direction. The overall diameter of the sleeve 10 is controlled by controlling the degree of winding, so as to achieve the purpose of occupying a smaller installation space. It is generally a redundant setting, and it cannot be over-wound or overfilled with wires. Under normal circumstances, a horizontal wire entry port A is formed between one side of the outer tube section 11 and the transition tube section 12, that is, the hook tooth portion 111 is opened by external force to separate it from the hook tooth groove 121, and it can be automatically separated under the action of external tension. At the same time, the horizontal wire entry port A is formed. At this time, the thickness of the inner spiral wire groove becomes larger, which is convenient for laying or taking out wires.

[0034] Furthermore, specifically, the concave side surface of the transition pipe section 12 is smoothly connected to the concave side surface of the outer pipe section 11 and the concave side surface of the inner rolled pipe section 13, so as to make the spiral wire groove B smooth and avoid wire jamming. The thickness of the transition pipe section 12 is greater than that of the outer pipe section 11 and the inner rolled pipe section 13. This design aims to reduce the length of the hook tooth portion 111. At the same time, in the installed state, one side edge of the transition pipe section 12 seals the opening of the spiral wire groove B to avoid the internal wires directly acting on the hook tooth portion 111, thereby preventing the hook tooth portion 111 and the hook tooth groove 121 from being accidentally unlocked.

[0035] Furthermore, specifically, a plurality of wire grooves 131 are provided on the outer spiral surface of the inner rolled tube section 13 along its length direction. The purpose of providing the wire grooves 131 is, on the one hand, to increase the number of wires within different diameter ranges that can be threaded, and on the other hand, to limit the migration of the wires along the spiral direction of the spiral wire groove B, thereby ensuring the orderly and structured threading.

[0036] Furthermore, specifically, in order to achieve the docking of adjacent sleeves 10, positioning holes 132 and positioning pins 133 are respectively provided at both ends of the inner side of the inner rolled pipe section 13, and the positioning holes 132 and positioning pins 133 between adjacent sleeves 10 cooperate with each other. At the same time, slots 122 and plugs 123 are respectively provided at both ends of the transition pipe section 12, and the slots 122 and plugs 123 between adjacent sleeves 10 cooperate with each other, so as to achieve that the spiral winding of adjacent sleeves 10 is kept as consistent as possible.

[0037] Further, specifically, the sleeve 10 is fixed by the clamp 20, and one side of the outer tube section 11 is in contact with the middle of the clamp, and the clamp squeezes the hook tooth portion 111 to avoid unlocking due to external factors.

[0038] Embodiment 2

[0039] like Figure 4 As shown, the inner rolled pipe section 13 provided in the first embodiment is a solid PVC pipe in the actual threading and winding process. When controlling the overall winding of the sleeve 10, a large force is required to overcome the internal tension of the sleeve 10 to achieve the winding effect. For this reason, a through groove 134 is further provided in the inner rolled pipe section 13. The through groove 134 is spiral and runs through the two ends of the inner rolled pipe section 13. The effects of this design include at least the following points:

[0040] Firstly, by providing the through groove 134 , the internal tension that needs to be overcome when rolling up the inner rolled tube section 13 can be effectively reduced. To a certain extent, this can also be understood as reducing the thickness of the inner rolled tube section 13 to reduce the internal tension generated by rolling up.

[0041] Secondly, during the actual threading and laying, the inner rolled tube section 13 is divided into two by the through groove 134. During the winding process, the inner rolled tube sections 13 on both sides are deformed with small internal tension, which will not cause excessive extrusion to the wires, and protect the internal structure of the wires from damage. At the same time, when threading and laying cables with different diameters, the inner rolled tube sections 13 on both sides can be deformed to different degrees along the spiral winding direction to ensure the positioning of the wires and ensure the overall order of the threading.

[0042] Furthermore, the through grooves 134 formed between the plurality of sleeves 10 in a connected state can also serve as heat dissipation channels to avoid the accumulation of self-heating of the cables when they are entangled or disturbed, thereby ensuring the stability of power supply.

[0043] 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 and the inventive concept of the present utility model, making equivalent substitutions or changes, shall be covered by the protection scope of the present utility model.
