Description

Technical Field

[0001] The utility model relates to a tool for binding iron wires. Background Art

[0002] Regarding the connection of hoses, there are currently many connection methods, mainly including threaded connection, clamp connection, flange connection, etc. However, these connection methods are all named after pipe fittings, and how to connect hoses to these pipe fittings is rarely mentioned.

[0003] As a factory product, the basic connection method between the hose and the pipe joint is that the hose is put on the joint of the pipe joint to form a mechanical connection based on the contraction of the hose. This method is suitable for occasions where the hose delivery pressure is relatively low. In some implementations, before the hose is put on the joint, rubber is applied to the surface where the joint and the hose are combined, thereby forming a chemical bond, i.e., bonding, in addition to the mechanical connection formed by the aforementioned contraction of the hose. This method has a wide range of uses, but it is mostly suitable for completion in the factory stage and is rarely used on site. The main reason is that chemical bonding requires the rubber to fully exert its bonding ability before it can be used, which requires waiting for a sufficiently long time, and the site often has relatively high requirements for time.

[0004] Another common connection method is the clamp connection. The clamp connection also requires first putting the hose on the joint of the pipe joint, then moving the clamp to the predetermined position, and tightening the clamp to achieve the connection. The clamp is a commonly used connector for hoses and joints on site, and it has strong bearing capacity and good stability. However, it also has some insurmountable defects. The main one is that the clamp is generally a metal part, and it is necessary to avoid plastic deformation during storage and transportation. Once plastic deformation occurs, it may cause wrinkles in the clamped hose, which is prone to water leakage. The clamp connection has relatively high requirements for storage and transportation, and the clamp usually has relatively high requirements for the pipe diameter, although its application has a certain scope of application.

[0005] At present, there is a relatively simple connection method, that is, the connection method of using wire bundling. Although there are various new connection methods for hoses and pipe joints, the connection method of wire bundling is suitable for almost all hose connections, with very good flexibility and low cost. Therefore, even if the wire is not smooth enough in some parts, the part can be cut off without too much consideration of cost issues, so it has a very wide range of applications.

[0006] The traditional wire bundling method is to wrap the wire around the pipe head two to three times (in some applications with relatively low sealing requirements, only one circle can be wrapped), and then clamp the two ends of the wire with a vise. The operator holds the vise with both hands to wrap the two wire ends around each other to form a connection. Then cut off the excess wire and flatten the remaining wire wrapping head to make it roughly parallel to the pipe head.

[0007] As mentioned above, using a vise to bundle wires often requires both hands to assist in the operation, which is very easy to cause slippage. In addition, when using a vise to bundle wires, it is easy to cause the wires to break locally (usually at the root of the winding head). This to a certain extent indicates that the force on the wires is uneven, the bundling force of each turn of wire formed by the bundle is not the same, and the seal between the hose and the pipe head is relatively poor. In addition, the consistency of bundling wires using a vise is relatively poor, and the appearance effect is not good. Utility Model Content

[0008] The utility model aims to provide a wire bundling tool suitable for bundling hoses on pipe joints. The operation of the bundling tool is relatively stable and a bundling structure with relatively good consistency can be easily obtained.

[0012] A handle, mounted on the other end of the operating rod;

[0013] A pair of transverse screws, one on each side of the operating rod; and

[0014] The compression nut cooperates with the transverse screw and is used for compressing the iron wire wound around the transverse screw.

[0015] Optionally, the operating rod is a rod body with adjustable length.

[0016] Optionally, the operating lever is selected from:

[0017] The first operating rod comprises an outer sleeve and an inner sleeve or inner rod inserted into the outer sleeve, wherein the outer sleeve is provided with the handle, and the inner sleeve or inner rod is provided with the top; wherein the outer sleeve is provided with a pin hole, and the inner sleeve or inner rod is provided with a positioning bead spring pin;

[0018] The second operating rod comprises an outer sleeve and an inner sleeve or inner rod inserted into the outer sleeve, wherein the outer sleeve is provided with the handle, and the inner sleeve or inner rod is provided with the top; wherein the outer sleeve is provided with a set screw hole, and a set screw is provided accordingly to lock the inner sleeve or inner rod after the inner sleeve or inner rod is adjusted into place;

[0019] The third operating rod comprises an outer sleeve and an inner sleeve or inner rod inserted into the outer sleeve, wherein the outer sleeve is provided with the handle, and the inner sleeve or inner rod is provided with the tip; one of the outer sleeve and the inner sleeve or inner rod is provided with a fixing hole, and the other is provided with a group of adjustment holes, and the group of adjustment holes are distributed in the axial direction of the operating rod; a corresponding latch or adjustment screw is provided to fix the inner sleeve or inner rod after it is adjusted into place;

[0020] A fourth operating rod comprises an outer sleeve and an inner sleeve or inner rod inserted into the outer sleeve, wherein the outer sleeve is provided with the handle, and the inner sleeve or inner rod is provided with the top; the outer sleeve has an internal thread, and the inner sleeve or inner rod has an external thread matching the internal thread; or

[0021] The fifth operating rod comprises a longitudinal screw rod and a female sleeve matched with the longitudinal screw rod, and the transverse screw rod is fixed on the female sleeve.

[0022] Optionally, the end of the operating rod has a threaded head, and the top has a threaded blind hole that matches the threaded head.

[0023] Optionally, the top is a conical structure, and a flange is provided at the bottom of the top.

[0024] Optionally, the flange is a square head or hexagon head bolt head structure.

[0025] Optionally, a wire threading hole is provided on the transverse screw rod for the wire to pass through.

[0026] Optionally, each transverse screw rod is provided with a thread threading hole.

[0027] Optionally, the handle is a crossbar vertically mounted on the operating rod.

[0028] Optionally, the clamping nut is provided with a backup nut.

[0029] In the embodiment of the utility model, the provided wire tying tool is used as follows:

[0030] First, fold the iron wire from the middle to form a parallel wire piece, one end of which is a threaded buckle and the other end has two wire heads. After the hose is put on the pipe head of the pipe joint, the iron wire piece is wound around the threaded buckle for one to two turns (because it is a parallel strand, one turn is equivalent to two turns of a single strand), and at least the end of the last turn passes through the threaded buckle. Then, the remaining iron wire is wound around the horizontal screw for two to three turns with two wire heads (corresponding to the two single strands in the parallel strand) as the guide, and the iron wire ring wrapped around the horizontal screw is compressed with a clamping nut. Then the top tip is pressed against the pipe head or the iron wire wrapped around the pipe head, and the handle is rotated around the pipe head to tighten the iron wire piece, and finally the iron wire piece is reversely bent with the threaded buckle as the bending point to form a lock buckle. Remove the wire bundling tool and cut off the excess iron wire.

[0031] Based on the above description, it can be known that, since the wire bundling tool of the embodiment of the utility model can be used to bundle with stranded wires, in order to meet the aforementioned convenience for the threading of the subsequent wire ring during winding, the stranded wires are roughly wound in a parallel manner, and the first circle needs to span the outside of the subsequent wound wire ring, so that the wire ring formed by winding is relatively tightly combined with the pipe head, and it is not easy to leak. In the embodiment of the utility model, the operation of the wire bundling tool has good certainty, because the symmetrical structure of the wire bundling tool determines that the operation before bundling is limited by the wire bundling tool. On the one hand, based on symmetry and rotation based on the pipe head, the operation is relatively stable. At the same time, based on the symmetry, the stranded wires need to cooperate, and the winding method of the wires is limited, which determines that the formed bundling structure has relatively good consistency. Since it is only necessary to bend the steel wire in the end, rather than forming a winding head, the bending will not cause fatigue fracture. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In view of the fact that in the embodiment of the utility model, the wire bundling tool provided is a small tool, and how to use it has been described in the aforementioned content, it will not be repeated here.

[0036] Furthermore, the wire bundling tool comprises a tip 1, an operating rod, a transverse screw 4, a clamping nut 3 and a handle 6, wherein the tip 1 is a pressure piece used as a contact part between the wire bundling tool and the pipe head after the stranded wires are wound around the pipe head.

[0037] Let's first explain the top, top 1 is Figure 1 The illustrated structure is a cone with a flange 11. The reason why the top 1, a component with a cone structure, is used is that the tip of the top 1 can better reduce visual obstruction and facilitate the operation of the wire binding tool.

[0038] The tip of the top 1 can be blunted to a spherical surface to avoid damaging the hose.

[0039] Regarding the taper of the tip 1, in order to reduce visual obstruction, the angle between the generatrix of the side of the tip 1 and the axis is expressed as no less than 15 degrees and no more than 20 degrees, and the optimal angle is 17 degrees. When the angle is relatively large, visual obstruction will become more and more obvious. When the angle is too small, the aforementioned passivation to a spherical surface is relatively difficult.

[0040] The top 1 and the operating rod can be an integral structure, and the top 1 is the end of the integral structure. In a preferred embodiment, a detachable connection structure is adopted between the top 1 and the operating rod, such as Figure 1 The threaded connection shown in the figure is adapted to different specifications of the top 1 according to different pipe joints.

[0041] To facilitate disassembly, Figure 1 In the structure shown, the top 1 has a flange 11, which is a structure similar to a thin bolt head, and can be a hexagonal bolt head structure or a square bolt head structure, so as to facilitate the disassembly and assembly of the top 1 with a wrench.

[0042] The flange 11 can be a round flange. At this time, the assembly reliability requirement of the top 1 is not high, and it can be used by manually tightening. At this time, the flange 11 is mainly convenient for holding the wire tying tool to be positioned at the pipe joint.

[0043] Accordingly, in some embodiments, the end of the operating rod has a threaded head, and a blind threaded hole 12 is formed at the large end of the tip 1, that is, the bottom of the cone.

[0044] Regarding the operating rod, it can be an assembly or a single piece. When a single piece structure is adopted, it can be made of a section of steel bar, one end of which is connected to the bottom of the conical head. The connection method can be the aforementioned blind threaded hole 12, or a non-detachable connection structure can be adopted, for example, the top 1 is welded to the end of the steel bar.

[0045] And as mentioned above, the operating rod and the tip 1 can be an integral structure, and the integral structure can be processed from a steel bar, for example, a cone is formed at the end of the steel bar.

[0046] Furthermore, a handle 6 is provided at the other end of the operating rod. The handle 6 can be a rod body to facilitate two-handed operation. Since some pipe joints are relatively small and can be operated with one hand, the handle 6 can be a wheel structure, and the axis of the wheel structure is parallel to the extension direction of the operating rod.

[0047] When the handle 6 is a rod, the whole is as follows Figure 2 In the state shown, the handle 6 can be a straight rod transversely welded to the upper end of the longitudinal screw rod 5, and the middle part of the straight rod is welded to, for example, the upper end of the longitudinal screw rod 5.

[0048] Both ends of the straight rod are rounded to reduce the occurrence of injuries caused by sharp corners.

[0049] The operating rod is a base member, and a pair of transverse screws 4 are arranged on the base member, and are installed on both sides of the operating rod, one on each side, and the installation method is mainly welding; the two transverse screws 4 are roughly as follows Figure 2 The symmetrical state shown is arranged on the operating rod, so that each strand of the stranded wire is pulled by the horizontal screw 4 in a symmetrical manner with respect to each other. It can also be seen that when the stranded wire is wound on the pipe head, the two single strands in the stranded wire are wound in a roughly symmetrical manner, and from the perspective of the force mode, the forces between the two single strands in the stranded wire are roughly equivalent, and it is easy to obtain a relatively good bundling effect.

[0050] As mentioned above, the two single strands in the parallel strand correspond to the horizontal screw 4 one by one, and are wound around the horizontal screw 4 two to three times. When the iron wire tied to the pipe head is tightened, the iron wire wound around the horizontal screw 4 is prone to slip and disengagement. Therefore, in order to ensure the reliability of the connection between the single strands and the horizontal screw 4, a clamping nut 3 cooperating with the horizontal screw 4 is used to tighten the single strand winding part after winding to avoid loosening.

[0051] In order to adapt to pipe joints with different pipe diameters, the operating rod is a rod body with adjustable length.

[0052] In order to achieve the adjustable length of the operating rod, the adjustable structure is exemplarily described in the following content. Any of the following structures for adjusting the length of the operating rod or the structure for adjusting the position of the cross screw 4 can be selected.

[0053] The first type of operating rod is a nested tube, which has an outer sleeve and an inner sleeve or inner rod inserted into the outer sleeve, that is, the outer sleeve is the main body, and the adjustable part is the inner sleeve or inner rod inserted into the outer sleeve. At this time, the outer sleeve constitutes the base for installing the handle 6, and the inner sleeve or inner rod constitutes the base for installing the top 1. Furthermore, the outer sleeve is provided with a pin hole, and the inner sleeve or inner rod is provided with a positioning bead spring pin, so that when the inner sleeve is adjusted into place, for example, the positioning bead on the positioning column spring pin will be stuck in the pin hole, and when adjustment is needed, the positioning bead is pressed down by hand and then adjusted.

[0054] The pin holes on the outer sleeve may have a row, and the arrangement direction of the row of pin holes is the extending direction of the operating rod.

[0055] The second operating rod also adopts a nested structure, and thus also has an outer sleeve and an inner sleeve or inner rod inserted into the outer sleeve, wherein the outer sleeve is installed with the handle 6, and the inner sleeve or inner rod is installed with the tip 1. Different from the pin connection of the second operating rod, the second operating rod adopts a set screw locking method, specifically, the outer sleeve is provided with a set screw hole, and a set screw is provided accordingly to lock the inner sleeve or inner rod after the inner sleeve or inner rod is adjusted into place. This method is simple, and the set screw locking can achieve stepless adjustment.

[0056] The third type of operating rod is an alternative to locking with a set screw, and also adopts a nested structure. Therefore, the third type of operating rod also has an outer sleeve and an inner sleeve or inner rod inserted into the outer sleeve, wherein the outer sleeve is installed with the handle, and the inner sleeve or inner rod is installed with the top; one of the outer sleeve and the inner sleeve or inner rod is provided with a fixing hole, and the other is provided with a group of adjustment holes, and the group of adjustment holes are distributed axially along the operating rod; corresponding pins or adjustment screws are provided for fixing the inner sleeve or inner rod after it is adjusted into position, and the position here is to align an adjustment hole with the fixing hole, at which time the adjustment screw can be inserted and then locked.

[0057] The fourth type of operating rod directly uses a threaded pair to achieve adjustment. This structure is relatively simple, and the adjustment is also stepless. Specifically, the fourth type of operating rod has an outer sleeve and an inner sleeve or inner rod inserted into the outer sleeve, wherein the outer sleeve is equipped with the handle, and the inner sleeve or inner rod is equipped with the top; the outer sleeve has an internal thread, and the inner sleeve or inner rod has an external thread that matches the internal thread

[0058] The fifth type of operating lever is as follows Figure 1 and Figure 2 The assembly structure shown in the figure comprises a longitudinal screw 5 and a female sleeve cooperating with the longitudinal screw 5, wherein the female sleeve is the threaded sleeve 2 shown in the figure, and the female sleeve can be adjusted on the longitudinal screw 5 to adjust the position of the transverse screw 4 installed on the female sleeve.

[0059] Accordingly, if Figure 2 As shown, a handle 6 is installed at the upper end of the longitudinal screw rod 5, and at the same time, the lower end of the longitudinal screw rod 5 is also connected to the top end 1 by a thread.

[0060] In order to further improve the reliability of the single-strand iron wire tied to the horizontal screw 4, a wire threading hole 10 is opened on the horizontal screw 4. The single-strand iron wire passes through the wire threading hole 10 and then is wound around the horizontal screw, which produces a mechanical locking effect and is not easy to loosen.

[0061] Each transverse screw only needs to have one threading hole 10 .

[0062] Also as a means of preventing slipping, the clamping nut 3 is provided with a backup nut.
