Description

Technical Field

[0001] The present invention relates to a device for preventing a needle threader from kinking and slipping, and more specifically, to a novel technology, which prevents the needle threader from kinking and can be rolled into a round shape when the needle threader is stored after use, and fixes the end portion of the needle threader by other means to prevent it from slipping into the interior of the device, thereby maintaining a state in which the needle threader can be easily separated from the device when it is used again. Background Art

[0002] Generally speaking, a fish tape (wire follower) is a tool used to insert various types of wires (for example, wires for supply and distribution of electricity and signals, telephone wires, and communication wires) into a building's protective tube. It is made by winding two or more piano wires or spring steel wires, which are made of materials that are less prone to bending.

[0003] After using this type of needle threader on site, it is stored for reuse, but since the needle threader is very long, it is stored in a state of being wound in a ring. However, when winding the needle threader, a twist may occur, or even if the winding is completed normally, it may fall apart during storage and become tangled or twisted.

[0004] As described above, if the threaders are knotted or kinked together, an action for re-untying them is required, which may cause problems such as delaying on-site work and increasing worker fatigue.

[0005] In order to solve the kinking problem of the needle threader as described above, the applicant has proposed a device for preventing the needle threader from kinking, such as Korean Utility Model No. 20-0487253. The device for preventing the needle threader kinking proposed in Korean Utility Model No. 20-0487253 inserts the needle threader through an insertion hole provided on one side outer surface of a semicircular tube body to introduce the needle threader at a specified position, thereby preventing the needle threader from kinking or tying a knot.

[0006] However, in the conventional technologies known so far including Korean Utility Model No. 20-0487253, there is a problem that one end of the threader protruding to the outside may slide into the inside of the tube due to shaking or vibration during storage or transportation.

[0007] As described above, if one end of the threader cannot be slid into the inside of the tube while maintaining the state of protruding outside the tube body, it is very difficult to find the one end of the threader and it takes a long time to untie the threader, which leads to low work efficiency.

[0039] Hereinafter, preferred embodiments of the present invention will be described in detail. Also, when describing the present invention, if it is determined that the detailed description of related known functions or structures does not necessarily make the gist of the present invention unclear, the detailed description will be omitted.

[0040] The present invention is characterized in that the device for preventing the threader from kinking and sliding is composed of the following components: a tube body 10, which is formed in an arc shape and has a wire W wound inside; a wire introduction prevention tube 20, which is connected to one side of the tube body 10 from the outside of the tube body 10 so that the insides are interconnected and one end W1 of the wire is inserted; and a sliding prevention member 30, which is arranged inside the wire introduction prevention tube 20, supports the wire W inserted into the wire introduction prevention tube 20 so that the one end W1 of the wire will not slide into the inside of the tube body 10.

[0041] The device for preventing a wire threader from kinking and slipping of the present invention is used to store various wires W (for example, metal wires, communication wires, power wires, iron wires, etc.) including a wire threader, and guides the wire W to be stored in a ring form inside a tube body 10 to prevent the wire W from kinking or getting knotted, and improves ease of use by preventing one end W1 of the wire from sliding into the tube body 10 or preventing one end W1 of the wire from being pulled out too far to the outside.

[0042] The tube body 10 is a structure in which the wire W is wound, and is formed of an arc shape corresponding to a portion of the wound loop so as to be guided into a loop shape. Since the threader suitable for the wire W has a certain degree of strength, even if it only corresponds to a portion of the wound loop shape, it can be guided and wound in a loop shape.

[0043] The tube body 10 is preferably made of synthetic resin material to facilitate mass production, and may be additionally coated to prevent the interior of the tube body 10 from being scratched during the insertion of the wire W.

[0044] The wire introduction prevention tube 20 of the present invention is another tube connected to the tube body 10 from the outside of the tube body 10, and its diameter is configured to be smaller than the diameter of the tube body 10. The wire introduction prevention tube 20 is connected to the channel of the tube body 10, and is configured in a form in which the path of the wire introduction prevention tube 20 is connected to the path of the tube body 10. Therefore, the wire W inserted into the wire introduction prevention tube 20 can be in a form extending to the inside of the tube body 10.

[0045] The wire introduction prevention tube 20 is a structure formed integrally with the tube body 10 and has a shape protruding toward the outside of the tube body 10. Figure 3 As shown, preferably, in order to have a clear sense of distinction, the inlet of the wire introduction prevention tube is separated from the tube body by a distance L, thereby improving the convenience of use.

[0046] And, if Figure 1 to Figure 2 As shown in FIG. 1 , preferably, the pipe body 10 and the wire introduction preventing tube 20 of the present invention are divided into two halves to constitute a first body 100 a and a second body 100 b .

[0047] As described above, when the first body 100 a and the second body 100 b are included, there is a structural advantage that the wire W can be easily taken out during use, and foreign matter inside can be easily removed.

[0048] When the first body 100a and the second body 100b of the present invention are connected to each other by the hinge part 200 separated and combined by a rotation axis, the convenience of use can be improved. Although the hinge part 200 can be formed only on the tube body 10, as shown in the figure, when it is formed on the tube body 10 and the wire introduction prevention tube 20 respectively, the hinge part 200 can be stably folded, and when the first body 100a and the second body 100b are folded, the wire introduction prevention tube 20 can abut each other at an accurate position.

[0049] Furthermore, preferably, the hinge portion 200 is disposed outside the arc of the tube body 10 so as to avoid interference during unfolding and folding.

[0050] In addition, a joint portion 300 is provided at the portion where the first body 100a and the second body 100b abut against each other, so as to maintain the joint state when the first body 100a and the second body 100b abut against each other. The joint portion 300 can be in various forms, for example, Figures 4 to 5 As shown in , a concave and convex shape can be formed to be inserted and combined with each other.

[0051] As described above, the anti-slip member 30 of the present invention is a structure that can be disposed inside the wire introduction prevention tube 20 to support the wire W inserted into the wire introduction prevention tube 20 so that one end W1 of the wire does not slide into the tube body 10 .

[0052] Therefore, the slide preventing member 30 of the present invention can be generally composed of two types of embodiments. First, as Figures 1 to 3 As shown in the figure, the first embodiment is characterized in that it has the following structure: a rubber tube 31 made of elastic material matching the inner diameter of the wire introduction prevention tube 20 is applied and inserted into the wire introduction prevention tube 20, and the wire W is inserted in the form of passing through a hollow portion 31a set in the center of the rubber tube 31, and the outer peripheral surface of one end portion W1 of the wire is tightly attached to the inner side of the hollow portion 31a and supported by the hollow portion 31a to prevent the wire W from sliding.

[0053] The anti-slip member 30 of the first embodiment uses a rubber tube 31 of elastic material, and a hollow portion 31a corresponding to the diameter of the wire W is provided through the center of the rubber tube 31, and the wire W can be inserted into the hollow portion 31a, thereby fixing the wire W in a non-slip manner by friction. At this time, the shape of the hollow portion 31a can be formed not only in a circular shape, but also in various shapes, such as a quadrangular shape, a hexagonal shape, an octagonal shape, a star shape, etc.

[0054] The rubber tube 31 is not divided but is formed in a single structure. After the wire introduction prevention tube 20 installed in the first body 100a or the second body 100b, it can be combined together through the hinge part 200 and the combination part 300. In order to prevent the flow of the rubber tube 31, a clamping flange can be provided inside the wire introduction prevention tube 20 or a groove can be provided outside the rubber tube 31 to fix the rubber tube 31 so that it does not move.

[0055] Figure 6 3 is a diagram showing another embodiment in which a pressurizing ring 40 is further applied to the first embodiment. The outer diameter of the wire introduction prevention tube 20 is set to gradually increase, and the pressurizing ring 40 is inserted in the state where the wire W is inserted so as to be sleeved on the outside of the wire introduction prevention tube 20 to transmit a force pressing toward the inside of the rubber tube 31, thereby further increasing the force for fixing the wire W.

[0056] More specifically, if Figure 7 As shown, when the pressurizing ring 40 is placed on the front portion of the wire introduction prevention tube 20 , since the diameter of the pressurizing ring 40 is almost the same as the outer diameter of the wire introduction prevention tube 20 , no pressure caused by the pressurizing ring 40 is generated.

[0057] Then, in order to fix one end W1 of the wire into the wire introduction prevention tube 20, as shown in FIG. Figure 8As shown, the pressurizing ring 40 is pushed toward the portion with a larger diameter to generate pressure pressing the inside of the wire introduction prevention tube 20. In this process, the rubber tube 31 is pressed with slight deformation of the wire introduction prevention tube 20, so that the portion where the pressurizing ring 40 is located can fix the wire W by a stronger pressure.

[0058] When the wire W is separated, the reverse order can be followed to remove the pressurizing ring 40. Preferably, the outer side of the wire introduction prevention tube 20 protrudes to form a blocking portion 21 to prevent the pressurizing ring 40 from being inserted too deeply. In addition, the user can knuring the surface of the pressurizing ring 40 or set a separate handle to make the movement of the pressurizing ring 40 smoother.

[0059] Figures 9 and 10 1 is a diagram showing a second embodiment of a sliding prevention member 30 of the present invention, which is characterized in that it has the following structure: a protrusion 32 integrally formed with the inner side of a wire introduction prevention tube 20 is applied, and the protrusion 32 is in close contact with the outer peripheral surface of one end portion W1 of the wire to support the wire W to prevent it from sliding.

[0060] The protrusion 32 is formed integrally with the wire introduction prevention tube 20. The protrusion 32 may be provided at one location, but as shown in the figure, may also be provided at two or more locations to support at least two or more locations.

[0061] As described above, since the anti-slip member 30 in the form of the protrusion 32 is formed integrally with the interior of the introduction prevention tube, it has the advantages of improving manufacturing convenience, reducing production costs, and facilitating mass production.

[0062] However, since the protrusion 32 is integrally formed with the wire introduction prevention tube 20, it is difficult to apply rubber only to the protrusion 32. Therefore, preferably, a coating layer 32a made of a material with high friction (such as rubber) is further provided on the end portion of the protrusion 32. The surface of the coating layer 32a can be treated into a serrated shape to further increase the friction.

[0063] Fig.11 Another embodiment is shown, that is, a cutout window 400 is further provided on the tube body 10 of the present invention, so that the remaining amount of the wire W wound inside the tube body can be confirmed with the naked eye, thereby improving the convenience of use. Preferably, the cutout window 400 is formed long in the width direction of the tube body, thereby having a larger observable range.

[0064] Furthermore, the cutout window 400 may be configured so that the interior can be directly seen in the cutout state, however, the cutout portion may also be covered with a transparent material.

[0065] As mentioned above, although this invention was demonstrated referring to said embodiment, it is a matter of course that various deformation|transformation and implementation are possible within the scope of the technical idea of ​​this invention.
