Description

Technical Field

[0001] This application relates to the technical field of noodle twisters, and in particular to a single-bar adjustable noodle twister. Background Technology

[0002] With the development of the railway industry, China's electrified railway mileage has exceeded 100,000 kilometers. Maintaining this "aerial spider web" has become a core task in ensuring the nation's transportation lifeline. The overhead contact line is the key component of this network, and the contact wires can become twisted or deformed due to various reasons. Various specialized tools are used to correct these deformations, and the innovation of these tools is crucial for the stability of the contact network's operation. The contact wire straightener is a specialized tool used to precisely correct these deformed contact wires. By adjusting the contact surface between the contact wire and the pantograph using the contact wire straightener, the deformed contact wire is corrected, thereby ensuring the normal operation of trains.

[0003] There are two common types of noodle twisters on the market: flathead non-adjustable contact wire noodle twisters and Phillips head adjustable noodle twisters. Flathead non-adjustable contact wire noodle twisters typically have a handle with a clamp fixed to one end. The clamp has a groove for securing the contact wire. During use, the flathead non-adjustable contact wire noodle twister relies on gravity and the operator's manipulation of the handle to secure the clamp to the contact wire groove. However, when the operator loses torque, the clamp can easily detach from the contact wire groove, potentially causing the noodle twister to fall from a height, posing a safety hazard and making it inconvenient to use.

[0004] An adjustable cross-shaped noodle screwdriver typically consists of two perpendicular handles and a clamp located between them. One handle passes through the clamp and is connected to a tightening mechanism. A rotating mechanism is located at the end of the clamp to adjust the clamp's tightness. This results in a wide clamp head, making it unsuitable for use in confined spaces such as complex wiring or double-bearing double-conductor circuits. The two long, perpendicular handles occupy a significant amount of space, requiring the carrying of large tool bags during high-altitude operations. This hinders movement for workers climbing overhead contact line supports or using overhead arms, making the adjustable cross-shaped noodle screwdriver difficult to carry during high-altitude work.

[0005] Therefore, in order to address the aforementioned technical problems, it is necessary to provide a single-slot adjustable noodle twister. Utility Model Content

[0006] The purpose of this invention is to provide a single-line adjustable noodle twister, which can solve the problem of inconvenience for operators mentioned above.

[0007] The technical solution for the adjustable noodle twister provided in this application is as follows: A single-bladed adjustable noodle twister, comprising: A handle, wherein a through hole is provided in the handle and a thread is provided in the through hole; The chuck includes a stationary chuck, a movable chuck, a rotating pin, and a reset member. The stationary chuck is fixedly connected to one end of the handle. The stationary chuck and the movable chuck are hinged by the rotating pin. The reset member is located between the stationary chuck and the movable chuck to drive the movable chuck away from the stationary chuck. The adjustment mechanism includes an adjustment screw, a positioning part, and an adjustment section. The adjustment screw passes through the through hole, and one end of the adjustment screw passes through the movable clamp plate. The positioning part is installed on the adjustment screw to position the movable clamp plate on the adjustment screw. The adjustment screw is threadedly connected to the handle. The adjustment section is fixedly connected to the end of the adjustment screw away from the stationary clamp plate and is used to drive the adjustment screw to rotate.

[0008] In one or more embodiments of this utility model, the stationary clamp is located on the side close to the adjustment part.

[0009] In one or more embodiments of this utility model, the positioning part includes a positioning nut, a positioning inner washer, and a positioning outer washer. The movable clamp plate has an oblong hole, the adjusting screw passes through the oblong hole, the positioning inner washer and the positioning outer washer are both sleeved on the adjusting screw, and the movable clamp plate is located between the positioning inner washer and the positioning outer washer. The reset member abuts against the positioning inner washer, and the positioning nut is fixedly connected to the end of the adjusting screw that passes through the oblong hole.

[0010] In one or more embodiments of this utility model, the reset member includes a reset spring, the reset spring is located between the stationary clamping plate and the moving clamping plate, and one end of the reset spring abuts against the positioning inner shim, the other end abuts against the moving clamping plate, and the reset spring is sleeved on the adjusting screw.

[0011] In one or more embodiments of this utility model, a protective gasket is provided between the stationary clamping plate and the moving clamping plate, and one end of the return spring abuts against the positioning inner gasket and the other end abuts against the protective gasket.

[0012] In one or more embodiments of this utility model, the adjusting part includes a fixed base and an adjusting handle. The fixed base is fixedly connected to the end of the adjusting screw away from the stationary clamp plate, and the adjusting handle is fixedly connected to the fixed base. The adjusting handle is provided with a plurality of rotating grooves.

[0013] In one or more embodiments of this utility model, both the stationary clamping plate and the moving clamping plate are provided with rotating holes, the rotating pin passes through the rotating holes, and the two ends of the rotating pin are provided with slots, and the slots are fitted with buckles.

[0014] In one or more embodiments of this utility model, a reinforcing cylinder is fixedly connected to the stationary clamp plate, and the reinforcing cylinder is sleeved on the handle.

[0015] Compared with the prior art, the adjustable noodle twister of this utility model allows the operator to place the contact wire between the stationary clamp and the moving clamp when adjusting the contact wire. The stationary clamp and the moving clamp are aligned with the groove of the contact wire. Then, the adjusting part is rotated, which drives the adjusting screw to rotate. The rotation of the adjusting screw causes the moving clamp to move towards the stationary clamp, and the stationary clamp and the moving clamp clamp the groove of the contact wire. Then, the handle can be rotated to correct the contact wire.

[0016] Since the adjustment part and the handle are located on the same side of the chuck, the operator does not need to extend their arm to the other side of the contact line when clamping the chuck. This avoids the chuck obstructing the view of the tightening operation and makes the operation more convenient.

[0017] Meanwhile, during use, the adjusting part is used to adjust the clamp to tighten the contact line, preventing the dough twister from falling off accidentally. In addition, this application can be corrected with a single handle, which greatly reduces the structural size of the dough twister, significantly reduces its weight, and minimizes the space occupied by the dough twister head, making it convenient to use in complex thread environments.

[0018] Therefore, the adjustable noodle twister of this application has a simplified structure, light weight, small space occupation, is easy to carry, and can easily adjust the tightness of the clamp, and can adapt to various catenary installation scenarios. Attached Figure Description

Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0025] This application discloses a single-line adjustable noodle twister.

[0026] Reference Figures 1-3 An adjustable noodle twister includes a handle 1, a chuck 2, and an adjustment mechanism 3. The handle 1 has a through hole 11 with threads. The chuck 2 includes a stationary chuck 21, a movable chuck 22, a rotating pin 23, and a reset member 24. The stationary chuck 21 is fixedly connected to one end of the handle 1, and the stationary chuck 21 and the movable chuck 22 are hinged by the rotating pin 23. The reset member 24 is located between the stationary chuck 21 and the movable chuck 22. The adjustment mechanism 3 includes an adjusting screw 31, a positioning part 32, and an adjustment part 33. The adjusting screw 31 passes through the through hole 11, and one end of the adjusting screw 31 extends onto the movable chuck 22. The positioning part 32 is mounted on the adjusting screw 31 to position the movable chuck 22 on the adjusting screw 31. The adjusting screw 31 is threadedly connected to the handle 1, and the adjustment part 33 is fixedly connected to the end of the adjusting screw 31 away from the stationary chuck 21. Since the adjustment part 33 and the handle 1 are located on the same side of the clamp 2, the operator does not need to extend his arm to the other side of the contact line during the demonstration. At the same time, only the handle 1 can play a corrective role, which simplifies the specific structure of this application, makes it lightweight, occupies less space, is easy to carry, and allows for easy adjustment of the clamp tightness, thus adapting to various contact wire installation scenarios.

[0027] Both the stationary clamping plate 21 and the movable clamping plate 22 have rotating holes 25. The rotating pin 23 passes through the rotating hole 25. The two ends of the rotating pin 23 have slots 26, and the slots 26 are engaged with buckles 27. By using the cooperation of the slots 26 and the buckles 27, the rotating pin 23 is limited, thereby preventing the rotating pin 23 from disengaging from the rotating hole 25.

[0028] A reinforcing cylinder 4 is fixedly connected to the stationary clamp plate 21, and the reinforcing cylinder 4 is sleeved on the handle 1. The reinforcing cylinder 4 makes the operation more stable when the operator rotates the handle 1, and prevents the handle 1 from breaking during rotation.

[0029] In an optional embodiment, the grip 1 is provided with anti-slip texture 5 on the side away from the clamp 2. The anti-slip texture 5 makes it easier for the operator to grip and thus makes it easier for the operator to rotate the grip 1.

[0030] In this embodiment, the stationary clamp 21 is located on the side closer to the adjustment part 33. In other embodiments, the stationary clamp 21 may also be located on the side away from the adjustment part 33. By placing the stationary clamp 21 on the side closer to the adjustment part 33, it is easier for the operator to observe the stationary clamp 21 and thus engage the protrusion on the stationary clamp 21 into the groove of the contact wire.

[0031] The positioning part 32 includes a positioning nut 321, an inner positioning washer 322, and an outer positioning washer 323. The movable clamping plate 22 has a slotted hole 28, through which the adjusting screw 31 passes. The slotted hole 28 provides clearance when the adjusting screw 31 drives the movable clamping plate 22 to rotate, facilitating the rotation of the movable clamping plate 22.

[0032] The inner positioning washer 322 and the outer positioning washer 323 are both sleeved on the adjusting screw 31, and the moving clamp 22 is located between the inner positioning washer 322 and the outer positioning washer 323. The limiting of the inner positioning washer 322 and the outer positioning washer 323 facilitates the adjusting screw 31 to stably drive the moving clamp 22 to move. The reset member 24 abuts against the inner positioning washer 322, and the positioning nut 321 is fixedly connected to the end of the adjusting screw 31 that passes through the waist-shaped hole 28.

[0033] In an optional embodiment, after the positioning nut 321 is screwed to the appropriate position of the adjusting screw 31, the positioning nut 321 can be welded to the adjusting screw 31 to prevent the positioning nut 321 from falling off during long-term use.

[0034] By utilizing the cooperation of the positioning nut 321, the inner positioning washer 322, the outer positioning washer 323, and the reset member 24, the reset member 24 abuts against the inner positioning washer 322, driving the moving clamp 22 to rotate in the opening direction. Meanwhile, the positioning nut 321 and the outer positioning washer 323 abut against the other side of the moving clamp 22, thereby driving the moving clamp 22 to rotate in the clamping direction. In turn, the cooperation of the positioning nut 321, the inner positioning washer 322, the outer positioning washer 323, and the reset member 24 drives the moving clamp 22 to loosen or tighten.

[0035] In this embodiment, the reset component 24 includes a reset spring 241, which is located between the stationary clamping plate 21 and the movable clamping plate 22. One end of the reset spring 241 abuts against the positioning inner washer 322, and the other end abuts against the movable clamping plate 22. The reset spring 241 is sleeved on the adjusting screw 31. By using the reset spring 241 sleeved on the adjusting screw 31, bending of the reset spring 241 is prevented, making the movement of the movable clamping plate 22 driven by the reset spring 241 more stable.

[0036] A protective gasket 6 is provided between the stationary clamping plate 21 and the moving clamping plate 22. One end of the return spring 241 abuts against the positioning inner gasket 322, and the other end abuts against the protective gasket 6. The protective gasket 6 ensures that the return spring 241 abuts against the protective gasket 6. During the adjustment process of the adjusting screw 31, it will rotate, and the rotation of the adjusting screw 31 will easily drive the rotation of the return spring 241. The rotation of the return spring 241 will directly rub against the protective gasket 6, thereby reducing the damage of the return spring 241 to the stationary clamping plate 21.

[0037] The adjustment unit 33 includes a fixed base 331 and an adjustment handle 332. The fixed base 331 is fixedly connected to the end of the adjustment screw 31 away from the stationary clamp 21. The adjustment handle 332 is fixedly connected to the fixed base 331, and the adjustment handle 332 is provided with several rotating grooves. The arrangement of several rotating grooves makes it convenient for the operator to grasp the adjustment handle 332 with their fingers and rotate it.

[0038] In this utility model, an adjustable noodle twister allows the operator to adjust the contact wire by holding the handle 1 and placing the contact wire between the stationary clamp 21 and the movable clamp 22, so that the stationary clamp 21 and the movable clamp 22 correspond to the grooves of the contact wire. Then, the operator rotates the adjusting handle 332, which in turn drives the adjusting screw 31 to rotate. When the adjusting screw 31 rotates, it drives the movable clamp 22 to rotate toward the stationary clamp 21 through the thread in the through hole 11. The stationary clamp 21 and the movable clamp 22 clamp the grooves of the contact wire. Then, the operator can rotate the handle 1 to correct the contact wire.

[0039] When removing the noodle twister, simply rotate the adjusting handle 332 in the opposite direction. The reverse rotation of the adjusting handle 332 causes the adjusting screw 31 to rotate in the opposite direction. When the adjusting screw 31 rotates in the opposite direction, it moves in the opposite direction through the thread in the through hole 11. At the same time, driven by the return spring 241, it causes the moving clamp 22 to rotate away from the stationary clamp 21, thereby causing the moving clamp 22 to disengage from the groove of the contact line. At this time, manually move the handle 1 to disengage the stationary clamp 21 from the groove of the contact line.

[0040] During the process of correcting the contact line, since the adjustment part 33 and the handle 1 are located on the same side of the chuck 2, the operator does not need to extend his arm to the other side of the contact line when clamping the chuck 2. This avoids the chuck 2 obstructing the view of the tightening operation and facilitates the operation.

[0041] Meanwhile, during use, the adjusting part 33 adjusts the clamp 2 to clamp the contact line, preventing the dough twister from falling off accidentally. This application can achieve the corrective function with just a handle 1, which greatly reduces the structural size of the dough twister, significantly reduces the weight of the dough twister, and makes the head of the dough twister occupy less space, making it convenient to use in complex thread environments.

[0042] Therefore, the adjustable noodle twister of this application has a simplified structure, light weight, small space occupation, is easy to carry, and can easily adjust the tightness of the clamp, and can adapt to various catenary installation scenarios.

[0043] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0044] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
