Description

Technical Field

[0001] This utility model relates to the field of cable manufacturing technology, and in particular, to a cable threading corrugated pipe fixture. Background Technology

[0002] In cable laying, the external installation of corrugated conduits is a crucial measure to ensure line safety. Corrugated conduits are typically made of PE or PP material, with a corrugated surface that combines flexibility and pressure resistance, effectively resisting external pressure, sand and gravel friction, and animal bites. Their acid and alkali resistance and UV resistance allow them to adapt to complex environments such as outdoors and underground, preventing aging and damage to the cable insulation layer. Furthermore, the small bending radius of corrugated conduits facilitates installation around obstacles, and their smooth inner wall prevents damage to the cable sheath. They are commonly used in home wiring upgrades, industrial equipment wiring, and municipal engineering projects, significantly extending cable lifespan and reducing the risk of short circuits and leakage.

[0003] However, due to the flexibility of the corrugated pipe, the cable may get stuck in the gaps of the corrugated pipe during the manual insertion process. The interference between the two will prevent the cable from being inserted further. At this time, it is necessary to continuously adjust the end angle of the cable to continue to insert it into the corrugated pipe, which reduces the efficiency of cable insertion into the corrugated pipe. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a cable threading corrugated pipe fixture.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A cable threading corrugated pipe fixture includes a skeleton rod for fitting the corrugated pipe, and a fixing mechanism is provided at the end of the skeleton rod. The fixing mechanism is adapted to coaxially fix the end of the cable to the skeleton rod and pull the corrugated pipe out from the skeleton rod axially so that the corrugated pipe is fitted onto the cable.

[0007] Preferably, the skeleton rod is helical.

[0008] Preferably, there are two skeleton rods, and the two skeleton rods cooperate to form a twisted spiral structure.

[0009] Preferably, the skeleton rod is a helical spring.

[0010] Preferably, the fixing mechanism includes a fixing cylinder and a fixing member disposed within the fixing cylinder. The fixing cylinder is used for accommodating the insertion of the cable, and the fixing cylinder is coaxially disposed with the skeleton rod.

[0011] Preferably, the fastener includes a plurality of clamping plates distributed circumferentially, the plurality of clamping plates cooperating for engaging the insertion of the cable, and the plurality of clamping plates being adapted to retract synchronously to clamp the end of the cable.

[0012] Preferably, a clamping cylinder is flexibly provided axially inside the fixed cylinder, a plurality of clamping pieces are constructed on the clamping cylinder, a conical surface is provided on the inner wall of the fixed cylinder, the inner radial direction of the conical surface gradually decreases away from the skeleton rod, and the clamping pieces are elastic.

[0013] Preferably, the inner wall of the clamping piece is provided with a clamping flange.

[0014] Preferably, a spring is provided inside the fixing cylinder to abut against the clamping cylinder.

[0015] Preferably, a connecting rod is provided on the end face of the skeleton rod, the connecting rod passes through the fixing cylinder and the clamping cylinder in sequence, and the end of the connecting rod is provided with a limiting flange, and the connecting rod passes through the spring.

[0016] The beneficial effects of this invention are as follows: First, the corrugated pipe is sleeved and stored on the frame rod. Then, the end of the cable is coaxially fixed to the end of the frame rod through a fixing mechanism. At this point, pulling the corrugated pipe out of the frame rod allows it to be sleeved on the outside of the cable. Furthermore, since the end of the cable is clamped in the fixing mechanism, interference between the two is less likely to occur during the sliding sleeve process of the corrugated pipe and the cable, thus improving the efficiency of cable threading through the corrugated pipe.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1 , Figure 2As shown, a cable-threading corrugated pipe fixture includes a frame rod 1. The corrugated pipe is pre-stored by fitting it onto the frame rod 1. For example, the frame rod 1 can be a straight rod (not shown), in which case the pre-stored length of the corrugated pipe depends on the length of the frame rod 1. In a preferred embodiment, the frame rod 1 can be configured as a helical shape; for example, a helical spring, as used in the prior art, can also be used to construct the helical frame rod 1.

[0022] For example, there can be two skeleton rods 1 arranged in a twisted manner, in which case the two skeleton rods 1 cooperate to form a twisted spiral structure. It can be understood that in this example, the two skeleton rods 1 have basically the same height and diameter, which allows for the pre-storage of more bellows in the same floor space.

[0023] A fixing mechanism 2 is also provided at the end of the skeleton rod 1. The end of the cable can be coaxially fixed to the end of the skeleton rod 1 through the fixing mechanism 2. Then, the corrugated pipe can be pulled out from the skeleton rod 1 to be sleeved on the outside of the cable.

[0024] In some embodiments, the fixing mechanism 2 may include a fixing cylinder 3 and a fixing member 4 disposed in the fixing cylinder 3. When fixing the cable, the end of the cable can be inserted into the fixing cylinder 3. The fixing cylinder 3 is used to initially hold the cable in a position that is basically coaxial with the frame rod 1. Then, the fixing member 4 can be used to fix the end of the cable.

[0025] For example, the fastener 4 may include a plurality of clamping plates 5 distributed circumferentially, which will eventually be inserted between the clamping plates 5 as the cable end is inserted into the fixing cylinder 3. The clamping plates 5 are designed to retract synchronously, thereby fixing the cable to the fixing cylinder 3 by clamping the cable end.

[0026] In a possible example, several clamping plates 5 can be synchronously retracted via a motor-actuated cam mechanism (not shown). Alternatively, a spring can be provided inside the fixed cylinder 3, with the end of the spring abutting against the clamping cylinder 6. This allows the clamping cylinder 6 to slide to varying degrees within the fixed cylinder 3 by axially compressing the spring, and the aforementioned clamping plates 5 are constructed on the clamping cylinder 6. Furthermore, a conical surface 7 is provided on the inner wall of the fixed cylinder 3, and the inner diameter of the conical surface 7 is designed to decrease towards the opening of the fixed cylinder 3.

[0027] Imagine that when the end of the cable is inserted into the clamping cylinder 6, the clamping cylinder 6 will be pushed away from the conical surface 7 by the pushing force of the operator's hand, and the clamping plates 5 will be in a state of mutual opening so that the end of the cable can be smoothly inserted into the clamping cylinder 6; when the operator releases the cable, the clamping cylinder 6 will approach the conical surface 7 under the action of the spring, that is, the ends of the clamping plates 5 will abut against the conical surface 7, and then under the constraint of the conical surface 7, the clamping plates 5 will retract inward to clamp and fix the end of the cable.

[0028] Furthermore, even if the corrugated tube pushes against the cable surface during installation, the cable experiences a pulling force from the clamping cylinder 6. However, under the constraint of the conical surface 7, this pulling force is converted into a clamping force on the cable end. In other words, the cable exhibits a usage state where the further it is pulled out of the clamping cylinder 6, the tighter the clamping becomes. This makes it less likely for the cable end to fall out of the clamping cylinder 6 during the installation of the corrugated tube.

[0029] In a specific example, the inner wall of the clamping piece 5 may also be provided with clamping flanges 8, and multiple clamping flanges 8 may be distributed axially. The clamping flanges 8 can exert greater friction on the cable end, thereby achieving a more secure clamping effect on the cable end.

[0030] In some embodiments, a connecting rod 9 is provided on the end face of the skeleton rod 1, and the connecting rod 9 passes through the fixed cylinder 3 and the clamping cylinder 6 sequentially along the axial direction. Furthermore, a limiting flange 10 is provided at the end of the connecting rod 9 to stop the clamping cylinder 6, preventing it from falling out of the fixed cylinder 3. The connecting rod 9 also provides guidance for the sliding of the clamping cylinder 6, resulting in higher sliding stability of the clamping cylinder 6.

[0031] It is understood that the skeleton rod 1 in this disclosure can be set on the frame or workbench, and a winding frame for winding cables can also be set on the frame. The method of fixing the skeleton rod 1 on the frame is something that those skilled in the art should know and understand, and will not be described in detail here.

[0032] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
