[0034] It needs to be explained that the existing threading device for building water and electricity installation usually does not have tension sensing function, and when the cable is pulled through the guide cable, the tension cannot be controlled, which can easily cause excessive wear of the cable insulation layer. In view of this, under the set pressure, the wire groove wheel 110 can move towards the cross arm 120; the guide wheel frame 100 further comprises a stop rod 140, one end of the stop rod 140 is fixed on the cross arm 120, and the other end of the stop rod 140 is located on the moving path of the wire groove wheel 110; wherein, in the state that the wire groove wheel 110 abuts against the stop rod 140, the stop rod 140 can limit the rotation of the wire groove wheel 110, so as to provide buffer through the movement of the wire groove wheel 110 when the tension of the guide cable is greater than the set tension, avoiding directly pulling off the cable, and at the same time, the wire groove wheel 110 is locked by the stop rod 140, avoiding the guide cable continuing to pull the cable, and causing excessive wear of the surface of the cable.

[0036] On this basis, one side of the wire groove wheel 110 is fixed with a stop disc 111, the stop disc 111 is a toothed disc, so as to limit the rotation of the wire groove wheel 110 through the cooperation of the stop disc 111 and the stop rod 140, to ensure that the stop rod 140 can limit the rotation of the wire groove wheel 110.

[0037] Usually, both sides of the wire groove wheel 110 are provided with stop discs 111, the stop rod 140 extends along the moving direction of the axis of the wire groove wheel 110, and one end of the stop rod 140 opposite to the wire groove wheel 110 can abut against both of the stop discs 111, to ensure that the forces on both sides of the wire groove wheel 110 are balanced when the wire groove wheel 110 brakes.

[0038] It can be understood that the cross arm 120 and the support rod 130 are both made of aluminum alloy, to reduce the weight of the guide wheel frame 100 on the premise of ensuring that the guide wheel frame 100 has sufficient structural strength.

[0039] The hand pump vacuum chuck 200 is hinged to the guide wheel frame 100, so that the guide wheel frame 100 can adapt to the installation condition at the corner of the wall surface.

[0041] At the same time, the hardness of the flexible silica gel ring 230 is 5-10 °A, so as to ensure that the flexible silica gel ring 230 has sufficient flexibility and support.

[0042] It should be noted that the air pump 220 is a standard product, and is equipped with a deflation valve, which can remove the vacuum of the rigid chuck after construction is completed, and can be directly purchased on the corresponding manufacturer and e-commerce platform. Common specifications are 3 inches, 4 inches and 6 inches, which are not the invention points of the present application, and only need to communicate the air outlet with the inner cavity of the rigid chuck. The embodiment of the present application will not be described in detail.

[0043] In summary, the threading auxiliary device for building water and electricity installation provided by the embodiment includes a guide wheel frame 100 and a hand pump vacuum chuck 200. The guide wheel frame 100 is provided with a wire groove wheel 110. The hand pump vacuum chuck 200 is installed at the lower end of the guide wheel frame 100. The hand pump vacuum chuck 200 includes a rigid disc body 210 and an air pump 220.

Due to the good flexibility, sufficient thickness and width of the flexible silica gel ring 230, the flexible silica gel ring 230 can completely fit the wall surface, thereby sealing the gap between the rigid chuck and the wall surface. Then, the air pump 220 is used to suck the cavity surrounded by the flexible silica gel ring 230, so as to obtain a high vacuum degree, so as to stably adsorb the hand pump vacuum chuck 200 on the wall surface, thereby stably installing the wire groove wheel 110 on the smooth wall surface, and then guiding the pull rope through the wire groove wheel 110. The pull rope is guided by the puller.

[0045] When the guiding cable force is greater than the set force, the pressure of the guiding cable acting on the wire groove wheel 110 is greater than the pre-tightening pressure of the pre-tightening spring 150 acting on the first limiting ring 131, so as to drive the wire groove wheel 110 to move towards the cross arm 120 until the stop disc 111 abuts against the end of the stop rod 140, so as to now rotate the wire groove wheel 110 through the stop rod 140, so as to make the guiding cable unable to continue to pull. Thus, the buffering is provided through the movement of the wire groove wheel 110, the cable is avoided from being directly pulled off, the wire groove wheel 110 is locked through the stop rod 140, the guiding cable is avoided from continuing to pull the cable, and the excessive damage of the cable surface is avoided. When the above-mentioned situation occurs, the operator is facilitated to be reminded that the pulling force is large in the threading process, and corresponding dredging measures are taken.

[0046] In conclusion, the threading auxiliary device for building water and electricity installation can be stably installed on the smooth wall, so as to guide the pull rope entering and exiting from the wall, facilitate the automatic winding and pulling of the guiding cable by the line pulling device, reduce the labor intensity of the cable threading and improve the threading efficiency, meanwhile, the cable is avoided from being pulled off and the excessive damage of the cable surface is avoided in the pulling process.
