Description

Technical Field

[0001] The invention relates to the field of corrugated pipe threading equipment, and more particularly to a handheld corrugated pipe threading device and a use method thereof. Background Art

[0002] In order to better protect the cable harness, an open corrugated tube is usually installed on the outside of the harness to effectively prevent the harness from external damage. When threading the wires in the corrugated tube, manual threading is usually adopted. After opening the opening of the corrugated tube by hand, the harness is placed in the corrugated tube. The opening of the corrugated tube can easily scratch the harness and hands. When completing a long threading distance, the thrust required for the corrugated tube to move forward along the harness is large, and the corrugated tube can easily detach from the harness, which will reduce work efficiency. The end and opening of the corrugated tube rub against the harness for a long time, and there is a risk of scratching the harness, which poses a certain safety hazard. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide an easy-to-use handheld corrugated pipe threading device and a method of using the same, which can automatically guide a wire harness into an open-type corrugated pipe to improve threading efficiency.

[0004] To achieve the above object, the technical solution adopted by the present invention is:

[0005] A handheld corrugated pipe threading device comprises a guide pipe, a wire conveying pipe, an anti-dropping sleeve, a V-shaped top block and a handle. The bottom of the handle is arranged with a limiting groove, the V-shaped top block is arranged with a clamping groove and a base, and the guide pipe is arranged with a mounting groove and a through hole.

[0006] Beneficial effect: the outer cylindrical surface of the line inlet end of the transmission tube penetrates into the inner cylindrical surface of the guide tube through hole, constraining the axial freedom of the transmission tube. After being fixed, the wire harness can be effectively guided to quickly pass through the transmission tube and be embedded in the corrugated tube. The base of the V-shaped top block is embedded in the guide tube installation groove for fixing. During the movement of the V-shaped top block along the through opening of the corrugated tube, the guide tube and the transmission tube can be driven to move in the same direction. The limit groove at the bottom of the handle cooperates with the slot of the V-shaped top block, effectively constraining the freedom of the handle, preventing the handle from being separated from the V-shaped top block when moving, and the handle can be held along the opening of the corrugated tube. The handle moves in the direction of the opening, driving the tip of the V-shaped top block to gradually open the opening of the bellows. The two sides of the V-shaped top block gradually increase the opening of the bellows. At the wire inlet end of the wire pipe, insert the wire harness into the wire pipe. After the handle continues to move, the opening of the bellows gradually decreases and returns to its normal size. Simultaneously, the wire harness is automatically embedded in the bellows, effectively avoiding the risk of scratches caused by the contact between the bellows opening and the wire harness. During the movement of the handle, the anti-fall-off sleeve can effectively prevent the bellows from separating from the guide tube, further avoiding the separation of the wire harness from the bellows.

[0007] Furthermore, the anti-dropping sleeve is arranged with an observation hole, a U-shaped hole, and a limiting boss, and the bottom of the handle is arranged with a limiting groove, and the limiting boss of the anti-dropping sleeve is assembled in cooperation with the limiting groove at the bottom of the handle.

[0008] Beneficial effects: the U-shaped hole of the anti-dropping sleeve moves along the direction of the V-shaped top block, and the anti-dropping sleeve limiting boss can be quickly inserted along the limiting groove at the bottom of the handle, and the circumferential rotation of the anti-dropping sleeve is constrained. The contact between the anti-dropping sleeve connecting plate and the line pipe can realize axial constraint of the limiting boss and the limiting groove, and the positioning is reliable. The smoothness of the movement of the bellows in the space between the falling sleeve and the guide tube and the recovery status of the bellows opening can be checked through the observation hole.

[0009] Furthermore, the V-shaped top block is arranged with an arc-shaped base, a V-shaped top block groove, and a V-shaped top block tip.

[0010] Beneficial effects: The arc-shaped base cooperates with the guide tube installation groove to constrain the V-shaped top block from rotating in a circle and moving in an axial direction along the guide tube. The V-shaped top block slot cooperates with the handle slot to achieve rapid positioning and installation of the handle and the V-shaped top block. When the tip of the V-shaped top block moves along the opening of the bellows, the opening of the bellows is gradually enlarged.

[0011] Furthermore, the guide tube, the anti-drop sleeve, and the handle are evenly arranged with weight-reducing holes along the circumferential direction, and the wire tube and the handle are hollow structures.

[0012] Beneficial effects: The weight-reducing holes and hollow structure can effectively reduce the weight of the handheld corrugated pipe threading device, reduce fatigue and improve efficiency during manual operation.

[0013] Furthermore, the line transmission pipe is arranged in the guide pipe, and the line outlet end of the line transmission pipe is arranged near the bottom of the guide pipe.

[0014] Beneficial effects: The wire harness is guided along the inlet end of the wire conveying tube, effectively avoiding the risk of scratches caused by the contact between the wire harness and the opening of the corrugated tube. The outlet end of the wire conveying tube is close to the bottom of the guide tube. After the wire harness is led out by the outlet end of the wire conveying tube, it can effectively ensure that the wire harness is automatically embedded in the bottom of the corrugated tube to prevent the wire harness from overflowing from the opening of the corrugated tube. During the synchronous movement of the wire harness and the corrugated tube, it can effectively avoid the wire harness from contacting with sharp parts such as the opening and end of the corrugated tube to ensure that the wire harness is not scratched.

[0015] Furthermore, the guide tube is connected to the handle via a V-shaped top block, the anti-drop sleeve is connected to the handle, and an annular space is formed between the guide tubes.

[0016] Beneficial effects: The space between the anti-drop sleeve and the guide tube is used to guide the bellows to move along the axial direction of the guide tube, thereby achieving consistency in the movement of the wire harness and the bellows along the axial direction, preventing the bellows from falling during movement, and realizing automatic embedding of the wire harness when the bellows passes through the space between the anti-drop sleeve and the guide tube.

[0017] Furthermore, the outer circumferential surface, inner circumferential surface, through hole, edges and the like of the guide tube, the line transmission tube, the V-shaped top block, the anti-drop sleeve and the handle are polished and smooth.

[0018] Beneficial effects: The outer cylindrical surface, inner cylindrical surface, through hole, edges and other parts of the handheld corrugated pipe threading device are polished and smooth, which can realize the smooth movement of the corrugated pipe in the space between the anti-drop sleeve and the guide pipe, and can effectively avoid scratches on the wire harness and avoid scratches on hands during manual operation.

[0019] A method for using a handheld corrugated pipe threading device comprises the following steps:

[0020] Hold the handle to insert the guide tube into the corrugated tube, move it along the opening direction of the corrugated tube, pass the tip of the V-shaped top block, so that the opening of the corrugated tube gradually increases, and after passing the inlet end, the opening of the corrugated tube gradually decreases and returns to its original state. When the end of the corrugated tube moves to the outside of the outlet end, insert the end of the wire harness into the wire transmission tube at the inlet end and move it to the outside of the outlet end, keep the relative position of the end of the wire harness and the end of the corrugated tube unchanged and fixed, continue to move the handheld handle, the anti-dropping sleeve is arranged with an anti-dropping sleeve limiting boss and an anti-dropping sleeve U-shaped hole, and the anti-dropping sleeve limiting boss is inserted into the handle limiting boss The groove constrains the anti-dropping sleeve to rotate in the circumferential direction and prevents the anti-dropping sleeve from falling off the handle. The anti-dropping sleeve connecting plate contacts the line inlet end of the wire transmission pipe to limit the axial movement of the anti-dropping sleeve. The space between the anti-dropping sleeve and the guide pipe is used to guide the corrugated pipe to achieve synchronous movement of the wire harness and the corrugated pipe, and automatically embeds into the corrugated pipe under the guidance of the wire transmission pipe to avoid the risk of scratches caused by direct contact between the wire harness and the opening of the corrugated pipe. The anti-dropping sleeve can effectively prevent the corrugated pipe from separating from the guide pipe, further avoiding the separation of the wire harness and the corrugated pipe, and improving work efficiency.

A handle slot 72 is arranged at the bottom of the handle 7. The handle slot 72 is installed in cooperation with the V-shaped top block slot 61 to effectively restrict the freedom of the handle 7 and prevent the handle 7 from being separated from the V-shaped top block 6 when moving. The guide tube 3 is arranged with a guide tube mounting groove 33 and a guide tube through hole 32. The V-shaped top block 6 is arranged with a V-shaped top block slot 61 and a V-shaped top block base 62. The V-shaped top block base 62 is embedded in the guide tube mounting groove 33 and fixedly connected. The guide tube mounting groove 33 limits the V-shaped top block base 62 from rotating in the circumferential direction and moving axially along the guide tube 3.

[0033] In the above embodiment, if Figure 4 As shown, the sealing end of the guide tube is tapered, which is conducive to guiding the guide tube to penetrate into the corrugated tube, and the guide tube through the hole is circular, which is conducive to matching with the inlet end of the line transmission pipe to penetrate.

[0034] In the above embodiment, if Figure 6As shown, the observation hole of the anti-dropping sleeve is in the shape of an oblong hole, a circular hole or a rectangular hole, and the cross-sectional shape of the anti-dropping sleeve limiting boss is in the shape of a V-shape or a T-shape.

[0036] A method for using a handheld corrugated pipe threading device comprises the following steps:

[0037] The guide tube 3 is inserted into the corrugated tube 1 by holding the handle 7, and moves along the direction of the opening 12 of the corrugated tube. The opening 12 of the corrugated tube is gradually enlarged by passing through the tip 63 of the V-shaped top block. After passing through the inlet end 42, the opening 12 of the corrugated tube is gradually reduced and restored to its original state. When the end 11 of the corrugated tube moves to the outside of the outlet end 41, the wire harness end 21 is inserted into the wire transmission tube 4 at the inlet end 42, and moved to the outside of the outlet end 41, keeping the relative position of the wire harness end 21 and the end 11 of the corrugated tube unchanged and fixed, and continuing to move the handheld handle 7, the anti-dropping sleeve 5 is arranged with an anti-dropping sleeve limiting boss 53 and an anti-dropping sleeve U-shaped hole 52, and the anti-dropping sleeve limiting boss 53 is inserted into the anti-dropping sleeve The anti-drop sleeve 5 is inserted into the handle limit groove 71 to constrain the anti-drop sleeve 5 to rotate in the circumferential direction and prevent the anti-drop sleeve 5 from falling off with the handle 7. The anti-drop sleeve connecting plate 55 contacts the line inlet end 42 of the line pipe to limit the axial movement of the anti-drop sleeve 5. The space between the anti-drop sleeve 5 and the guide tube 3 is used to guide the corrugated tube 1, so as to realize the synchronous movement of the wiring harness 2 and the corrugated tube 1, and automatically embed into the corrugated tube 1 under the guidance of the line pipe 4, so as to avoid the risk of scratches caused by direct contact between the wiring harness 2 and the corrugated tube opening 12.
