Description

Tool for threading

Technical Field

The utility model relates to a threading tool, in particular to a special accessory tool for a suction line for concealed conduit threading.

Background

In the current home decoration and construction sites, indoor concealed wiring becomes a mainstream, safe and beautiful wiring mode. The main construction method of the existing indoor concealed wire is to reserve a PVC wire pipe when a house is built, and start the construction operation of the indoor concealed wire after the civil engineering is finished. The general construction method is that firstly, a complete pipeline inlet end and outlet end are determined, then a threading steel wire is inserted into a spool from an inlet, and when the friction force is large in the middle inserting process, the threading steel wire needs to be slowly rotated and twisted until the other end of the spool is exposed, so that the steel wire penetrates through the whole spool. After the steel wire break-over spool, fix the cable conductor in steel wire one end, the artifical steel wire that stimulates of the other end, pass the spool until whole cable conductor, loosen steel wire and cable conductor. The main bottleneck link causing low threading construction efficiency at present is a link that a threading steel wire penetrates through a spool, and the main method at present comprises manual rotation and twisting; the poking and twisting of the electric tool are not good, and particularly when building particles and impurities exist in the pipeline, the pipeline needs to be cleaned up to continue the lead threading operation, which is labor-consuming and time-consuming.

Fig. 10 to 11 show the use of the operating tube assembly when the cassette is on a vertical wall surface and when the cassette 6 is on the ceiling of an indoor wall, respectively.

The hard elbow can be set into two forms of a convex hard elbow 4.1 (shown in figure 3) and a concave hard elbow 4.2 (shown in figure 4), the convex hard elbow 4.1 and the concave hard elbow 4.2 can be replaced according to the requirement and can be assembled on the transparent pipe 4.3; the convex hard elbow 4.1 comprises a soft sealing element I4.11 and a hard elbow main body I4.12, wherein one end (namely the head) of the hard elbow main body I4.12, which is far away from the end connected with the transparent pipe 4.3, is provided with a flange used for being inserted into a lock nut port or a line pipe port 7 in the line box 6, and the soft sealing element I4.11 is arranged to form sealing with the end or an inner port of the lock nut port or the line pipe port; as an embodiment, a soft sealing piece one 4.11 is arranged at the outer side of the flange, and the soft sealing piece one 4.11 is in a regular shape such as an O-shaped ring or a sealing gasket; the hard elbow can also be an inward concave type hard elbow 4.2, and comprises a soft sealing element II 4.21 and a hard elbow main body II 4.22, wherein one end (namely the head) of the hard elbow main body II 4.22, which is far away from the end connected with the transparent pipe 4.3, is provided with a concave part for being sleeved on the outer diameter of the end part of a lock nut port or a line pipe port 7 in the line box 6, and the soft sealing element II 4.21 is arranged to form sealing with the end part or the outer port of the lock nut port or the line pipe port or the inner surface of the line box body; in one embodiment, a second soft seal 4.21 is provided inside the recess, and the second soft seal 4.21 has a regular shape such as an O-ring or a gasket.

In the actual threading operation, as shown in fig. 5 and 7, the operation tube assembly is moved in the arrow direction, so that the head of the hard elbow 4.1 or 4.2 is matched with the locking nut port or the line tube port 7 in the line box 6, the mode of the convex hard elbow 4.1 is inserted into the locking nut port or the line tube port 7, and the mode of the concave hard elbow 4.2 is sleeved on the outer diameter of the concave hard elbow, no matter the concave hard elbow is inserted into the locking nut port or the line tube port 7 or sleeved on the outer diameter of the locking nut port or the line tube port 7, so that an operator can achieve better alignment, force application and alignment positioning compared with soft matching in the operation process, simply and can know that the alignment is achieved more clearly, force application or time alignment is not needed, the convenience of the operation is changed, and the use experience and the use efficiency are improved; at the same time, a better sealing is ensured, since the soft sealing elements 4.11, 4.21 (see fig. 3-4) on the outer or inner diameter of the hard bends 4.1, 4.2 can form an end face seal with the locking nut or conduit opening 7 (see fig. 5 and 7); the end face seal is utilized, so that the end face seal can be easily and conveniently moved out while the sealing effect is achieved; when the lead 8 in the hidden pipe 9 is sucked out and the heads of the hard elbows 4.1 and 4.2 need to be separated from the lock female opening or the pipe orifice 7 (as shown in figures 6 and 8, the heads are separated along the arrow), larger side damping and friction force cannot be generated, and the operation can be performed easily and quickly; generally, the rigid elbow with the structure form of the rigid elbow 4.1 or 4.2 has the advantages that when an operator uses the tool, the operator can hold the telescopic pipe to lift or straighten (as shown in figures 10 and 11) so as to conveniently and quickly find the pipe orifice, and obvious positioning and limiting senses of finishing alignment are provided; whether the lead is sucked out or not can be seen more visually through the transparent tube, and after the lead 8 is sucked out, the separation action of the elbow and the lock nut or the line tube is more convenient, labor-saving and rapid.

As an alternative, the soft sealing element one 4.11 can also be arranged in the irregular shape of fig. 13, such as a taper shape or a slope shape, and the like, and is sleeved outside the flange of the hard elbow main body one 4.12; similarly, the soft sealing element two 4.21 may also be provided with an irregular shape such as a taper or a slope shape in its cross section, and is hermetically disposed on the concave inner side of the hard elbow main body two 4.22.

In addition, as an alternative, the soft sealing member two 4.21 may also be provided in the form shown in fig. 14, the soft sealing member two 4.21 is provided at the end of the hard elbow main body two 4.22, specifically, the soft sealing member two 4.21 may be provided at the end of the hard elbow main body two 4.22 by injection molding; when in use, the second soft sealing element 4.21 can directly abut against the inner surface of the wire box 6 to form sealing.

In actual operation, after the lead wire 8 is sucked out, the control switch 5.1 can be turned off by hand to stop sucking the lead wire after the lead wire is seen to be sucked out through the transparent tube 4.3, the dust collector 3 does not need to be turned off by walking or bending to the side of the machine, and operation is convenient and fast.

In practice, the control tube assembly 4 of the operating tube assembly 1 is rotatable relative to the hose 2 portion, that is, the control tube assembly 4 can be rotated freely as required to align with the locking nut ports or the ports of the conduit 7 on the respective faces in the wire box 6, but the hose 2 linked at the rear end does not generate rotation distortion to affect the operating feeling, which is also an improvement in the use experience and efficiency.

In actual operation, the transparent pipe 4.3 and the hard elbows 4.1 and 4.2 can be pulled out of the transparent pipe joint 4.4 as a combination, and the outer diameter of the joint 4.4 is wrapped by a soft sealing sleeve 4.5 with a certain diameter size; as shown in fig. 12, at this time, the transparent pipe joint 4.4 and the end of the soft sealing sleeve 4.5 are aligned with the large pipe orifice 11 in the distribution box 10, so that the suction line of the large diameter pipe in the distribution box, such as the large diameter pipe orifices 40mm and 32mm in a common distribution box, can be completed, and the operation is very convenient.
