Technical Field

[0001] This application relates to the field of shipbuilding technology, and in particular to a steel cable tie curling and tightening tool and a steel cable tie curling and tightening method. Background Technology

[0002] During the construction of the product vessel, after the cables are laid, they need to be tightly bound with steel cable ties to ensure they are secure and prevent loosening. The excess length of the cable ties after binding needs to be curled to avoid affecting the appearance and causing cuts to operators. Currently, a tuning fork-type straight rod is used to achieve this curling. Figure 1 As shown, the tuning fork 12 is inserted into the end of the steel cable tie, and the cable tie is wound by rotating the handle 11. This method requires reserved space for the rotating handle 11, and the tuning fork 12 is a rigid structure with a fixed length, which is easily subject to space constraints. Summary of the Invention

[0003] In a first aspect, embodiments of this application provide a steel cable tie coiling and tightening fixture, comprising: an operating mechanism and a spiral rod; wherein:

[0004] The operating mechanism includes a first handle, a second handle, a transmission mechanism, and a sleeve structure. The sleeve structure and the transmission mechanism are connected in a transmission connection. The sleeve structure is exposed through one side of the first handle. The second handle is rotatably connected to the first handle by a fixing screw and is also connected in a transmission connection to the transmission mechanism. Reciprocating relative to the first handle, the second handle can drive the sleeve structure to rotate in a preset direction through the transmission mechanism.

[0005] The screw rod includes an adjusting rod and a tuning fork rod connected together. The end of the adjusting rod is used to connect to the sleeve structure, and the sleeve structure can drive the tuning fork rod to rotate through the adjusting rod.

[0006] In some alternative embodiments, the screw rod further includes a universal joint, through which the adjusting rod and the tuning fork rod are connected.

[0007] In some alternative embodiments, the adjusting rod includes an inner rod and an outer rod, the outer rod being provided with a rod groove, and the inner rod being at least partially disposed in the rod groove and capable of extending and retracting relative to the outer rod within a predetermined axial length range.

[0008] In some optional embodiments, the outer rod is provided with a spring button, which is at least partially exposed on the surface of the outer rod; the inner rod surface is provided with at least two pin slots along the axial direction; by pressing the spring button, the pin on the spring button can be inserted into the pin slot to lock the relative position of the inner rod and the outer rod; when it is necessary to adjust the length of the adjusting rod, the spring button is pressed again, the pin of the spring button springs up, the inner rod is adjusted to extend or retract to the target length, and the spring button is pressed again to lock.

[0009] In some alternative implementations, the spring button is fixed to the outer sleeve by a cover plate, which is connected to the outer sleeve by screws.

[0010] In some optional embodiments, the transmission mechanism includes a first transmission gear, a second transmission gear, a reversing mechanism, and a rotating wheel; the first transmission gear is a double-layer gear with a main and auxiliary gear structure, the main gear of the first transmission gear meshes with the second transmission gear, the second transmission gear is coaxial with and fixedly connected to the reversing mechanism, the rotating wheel is fixedly connected to the sleeve structure, the rotating wheel is sleeved on the reversing mechanism and fixedly connected to the first handle, and the reversing mechanism can drive the rotating wheel to rotate along the preset direction;

By reciprocating the rotation of the second handle, the crescent gear can be driven to mesh with the auxiliary gear of the first transmission gear, thereby driving the first transmission gear to rotate. In turn, the second transmission gear drives the reversing mechanism to drive the rotating wheel to rotate in the preset direction, which in turn drives the sleeve structure to rotate in the preset direction.

[0012] In some optional embodiments, the reversing mechanism is provided with rotatable locking feet at both ends. One side of the locking feet is connected to both ends of the reversing mechanism by a spring. The spring supports the locking feet so that the locking feet are locked in the annular tooth groove inside the wheel, thereby enabling the steering mechanism to drive the wheel to rotate in the preset direction.

[0016] Insert the tuning fork rod into the end of the steel cable tie, and then fit the sleeve structure onto the end of the connecting and adjusting rod.

Detailed Implementation

[0031] In order to gain a more detailed understanding of the features and technical content of the embodiments of this application, the implementation of the embodiments of this application will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for reference and illustration only and are not intended to limit the embodiments of this application.

For example, it can refer to the internal connection of two elements, a direct connection, or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above term according to the specific circumstances.

[0033] It should be noted that the terms "first," "second," and "third" used in the embodiments of this application are merely used to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first," "second," and "third" can be interchanged in a specific order or sequence where permitted. It should be understood that the objects distinguished by "first," "second," and "third" can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in an order other than those illustrated or described herein.

[0034] Figure 2 This is a side view of the operating mechanism and the screw rod of a steel cable tie coiling and tightening fixture according to an embodiment of this application, in the unconnected state. This application embodiment provides a steel cable tie coiling and tightening fixture, such as... Figure 2 As shown, the steel cable tie coiling and tightening fixture includes: an operating mechanism 13 and a spiral rod 14.

[0035] like Figure 3 As shown, the operating mechanism 13 includes a first handle 21, a second handle 22, a transmission mechanism, and a sleeve structure 30. The sleeve structure 30 and the transmission mechanism are connected in a transmission manner. The sleeve structure 30 is exposed on one side of the first handle 21. The second handle 22 is rotatably connected to the first handle 21 by a fixing screw 23 and is also connected in a transmission manner to the transmission mechanism. The second handle 22 can drive the sleeve structure 30 to rotate in a preset direction by reciprocating relative to the first handle 21 through the transmission mechanism.

[0036] In some alternative implementations, such as Figure 3 As shown, the transmission mechanism includes a first transmission gear 27, a second transmission gear 25, a reversing mechanism 26, and a rotating wheel 24. The first transmission gear 27 is a double-layer gear with a main and auxiliary gear structure. The main gear of the first transmission gear 27 is meshed with the second transmission gear 25. The second transmission gear 25 is coaxial with and fixedly connected to the reversing mechanism 26. The rotating wheel 24 is fixedly connected to the sleeve structure 30. The rotating wheel 24 is sleeved on the reversing mechanism 26 and fixedly connected to the first handle 21. The reversing mechanism 26 can drive the rotating wheel 24 to rotate in a preset direction.

[0037] The second handle 22 is equipped with a crescent gear 29. By reciprocating the rotation of the second handle 22, the crescent gear 29 can be driven to mesh with the auxiliary gear of the first transmission gear 27, thereby driving the first transmission gear 27 to rotate. Then, the second transmission gear 25 drives the reversing mechanism 26 to drive the rotating wheel 24 to rotate in a preset direction, which in turn drives the sleeve structure 30 to rotate in a preset direction.

[0038] In some alternative implementations, such as Figure 4 and Figure 5 As shown, the reversing mechanism 26 is provided with rotatable locking feet 34 at both ends. One side of the locking feet 34 is connected to both ends of the reversing mechanism 26 by a spring 35. The spring 35 supports the locking feet 34 so that the locking feet 34 are locked in the annular tooth groove on the inner side of the rotating wheel 24. Thus, the steering mechanism can drive the rotating wheel 24 to rotate in a preset direction.

[0039] In some alternative implementations, the rotor 24 and the sleeve structure 30 are integrated.

[0040] In some alternative implementations, such as Figure 6 As shown, the second transmission gear 25, the reversing mechanism 26 and the rotating wheel 24 are sleeved on the pin 33, and the first handle 21 is fixedly connected to the end of the pin 33.

[0041] The screw rod 14 includes an adjusting rod 31 and a tuning fork rod 12 connected together. The end of the adjusting rod 31 is used to connect to the sleeve structure 30. The sleeve structure 30 can drive the tuning fork rod 12 to rotate through the adjusting rod 31.

[0042] In some alternative implementations, such as Figure 1 As shown, the sleeve structure 30 can be connected to the hexagonal head at one end of the adjusting rod 31 on the rotating rod. The sleeve structure 30 can be, for example, an internal hexagonal sleeve corresponding to the hexagonal head.

[0043] The above embodiments of this application can solve the problems of the inability to adjust the length of the rotating rod in the prior art, as well as the problems of limited functionality and inconvenient operation caused by space constraints. The technical solution of this application adopts reciprocating operation, with a small turning radius and lower space requirements, which can better meet the needs of on-site use.

[0044] In some alternative implementations, such as Figure 2 As shown, the screw rod 14 also includes a universal joint 32, through which the adjusting rod 31 and the tuning fork rod 12 are connected.

[0045] In some alternative implementations, such as Figure 7 As shown, the adjusting rod 31 includes an inner rod 37 and an outer rod 38. The outer rod 38 is provided with a rod groove 39. The inner rod 37 is at least partially disposed in the rod groove 39 and can extend and retract relative to the outer rod 38 within a preset axial length range.

[0046] In some alternative implementations, such as Figure 7 and Figure 8 As shown, the outer rod 38 is provided with a spring button 36, at least partially exposed on the surface of the outer rod 38; the inner rod 37 has at least two pin grooves 42 axially arranged on its surface; by pressing the spring button 36, the pin on the spring button 36 can be inserted into the pin groove 42 to lock the relative position of the inner rod 37 and the outer rod 38; when it is necessary to adjust the length of the adjusting rod 31, press the spring button 36 again, the pin of the spring button 36 pops up, the inner rod 37 is adjusted to extend or retract to the target length, and the spring button 36 is pressed again to lock it.

[0047] In some alternative implementations, such as Figure 8 As shown, the spring button 36 is fixed to the outer rod 38 by the cover plate 40, and the cover plate 40 is connected to the outer rod 38 by screws 41.

[0048] The steel cable tie is wound and tightened using the steel cable tie winding and tightening operation of the embodiment of this application. The tuning fork rod 12 can be inserted into the tail of the steel cable tie. The operator can hold the first handle 21 and the second handle 22 with both hands respectively, and reciprocate the second handle 22 around the fixing screw 23, which drives the crescent gear 29 to reciprocate. The crescent gear 29 meshes with the auxiliary gear of the first transmission gear 27, which drives the entire first transmission gear 27 to rotate. The main gear of the first transmission gear 27 meshes with the second transmission gear 25 on the reversing mechanism 26, which drives the reversing mechanism 26 to rotate.

[0049] When the second handle 22 is moved towards the first handle 21, that is, when the second handle 22 is rotated clockwise, the crescent gear 29 rotates clockwise, and the first transmission gear 27 also rotates clockwise under its drive. The first transmission gear 27 drives the reversing mechanism 26 to rotate counterclockwise. Figure 4As shown, the spring 35 inside the reversing mechanism 26 pushes the locking foot 34 outward, causing it to engage in the annular groove inside the rotating wheel 24. This causes the reversing mechanism 26 to rotate the rotating wheel 24 counterclockwise. The retaining sleeve on the rotating wheel 24 connects to the hexagonal head on the rotating rod, causing the rotating rod to rotate and thus coiling the steel cable tie. Conversely, when the second handle 22 rotates counterclockwise, the locking foot 34 on the reversing mechanism 26 rotates clockwise. The groove inside the rotating wheel 24 rotates in the opposite direction to the locking foot 34, so the reversing mechanism 26 will not rotate the rotating wheel 24, and the rotating rod will not reverse direction. This operation is repeated to achieve the coiling and tightening of the steel cable tie.

[0050] In the above embodiments of this application, Figure 3 The perspective is used to determine the clockwise and counterclockwise directions by looking straight ahead.

[0051] The technical solution of this application adopts reciprocating operation, with a small turning radius and low space requirements. It solves the problem that the rotating rod in the original solution cannot be adjusted in length, and can better meet the needs of on-site use.
