The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to the specific circumstances.

Fig. 1 and 2 show a threading device 10 according to some embodiments of the present invention, where the threading device 10 is used to drive a wire, a cable or other elongated element to move along a predetermined track to complete corresponding installation, and for ease of understanding, the cable is unified as the elongated element to be installed later, but in practical application, the threading device is not only capable of installing the cable, but also applicable to other elongated elements. As shown in fig. 1 to 4, the threading device 10 includes a housing 1, a rotating means 2, and a clutch means 3.

It can be appreciated that the housing 1 is used for mounting the rotating device 2 and the clutch device 3, and the rotating device 2 is used for winding and unwinding, so as to drive the cable to move to complete the installation of the cable. The clutch device 3 is used for controlling corresponding parts on the rotating device 2 to carry out position locking in the winding and unwinding process, and the position locking comprises position locking among different parts of the rotating device 2.

As shown in fig. 3 to 6, the rotating device 2 includes a first rotating disc 21, a second rotating disc 22 and a traction member 23, the first rotating disc 21 is provided with a storage groove 211, the second rotating disc 22 is rotatably disposed in the storage groove 211, one end of the traction member 23 is connected with the second rotating disc 22, and the other end of the traction member 23 is led out from the edge of the outer groove wall of the storage groove 211 and penetrates through the housing 1.

It will be appreciated that, once the traction member 23 is drawn out, the traction member 23 is away from the first turntable 21 in a direction inclined to the bottom of the accommodating groove 211, so that the first turntable 21 is prevented from obstructing the movement of the traction member 23 during the edge rotation, and particularly, the structure of the first turntable 21 defining the accommodating groove 211 is prevented from obstructing the drawing-in and drawing-out of the traction member 23.

As shown in fig. 3, the clutch device 3 includes a clutch mechanism 31. The clutch mechanism 31 may be configured to be disposed between the first turntable 21 and the second turntable 22.

As shown in fig. 3 to 6, when the second turntable 22 unwinds and rotates, the clutch mechanism 31 locks the relative positions of the first turntable 21 and the second turntable 22, so that the second turntable 22 drives the first turntable 21 to rotate together, and the traction piece 23 is supported by the groove wall of the accommodating groove 211 to unwind; when the second turntable 22 winds and rotates, the clutch mechanism 31 is unlocked, so that the second turntable 22 rotates in the accommodating groove 211, and the traction piece 23 winds in the accommodating groove 211.

As will be appreciated, the receiving slot 211 is adapted to receive the traction member 23. The first turntable 21 is used for driving the traction piece 23 to unwind, so that the traction piece 23 continuously penetrates out of the shell 1. The second turntable 22 is used for driving the traction piece 23 to roll, so that the traction piece 23 is not gradually retracted into the shell 1. The traction member 23 is used for driving the cable to move along the track, thereby completing the installation of the cable.

The clutch mechanism 31 is used to fix the relative positions of the first turntable 21 and the second turntable 22 when the traction member 23 is unreeled, so that the first turntable 21 and the second turntable 2 rotate together, and the common rotation means that the first turntable 21 and the second turntable 2 rotate at the same angular speed.

It should be noted that, when the second turntable 22 rotates in this direction, the pulling member gradually unwinds and sends out the housing 1. During the unreeling rotation of the second turntable 22, the clutch mechanism 31 locks the relative positions of the first turntable 21 and the second turntable 22, so that the first turntable 21 and the second turntable 22 rotate at the same angular speed in the unreeling rotation direction;

referring to fig. 4 and 5, during the unreeling rotation, the traction member 23 will unwind in the accommodating groove 211, and the traction member 23 itself has a certain self-unwinding tendency, so that the outermost ring of the traction member 23 in the accommodating groove 211 will expand and fit against the groove wall of the accommodating groove 211, then, with further rotation of the first turntable 21 and the second turntable 22, the traction member in the winding state will gradually unwind, the interaction force between the traction member 23 and the groove wall of the accommodating groove 211 will gradually increase, so that the friction force between the traction member 23 and the groove wall of the accommodating groove 211 increases, and the traction member 23 will be continuously sent out of the housing 1 during the rotation;

In the unreeling rotation process, even if the drag force borne by the traction piece 23 is larger, so that the clamping stagnation occurs in the transmission of the traction piece 23, the traction piece 23 can be further unreeled under the drive of the second turntable 22, so that the traction piece 23 in a winding state is further unreeled, further the subsequent unreeled part of the traction piece 23 can be expanded and propped at the outermost part of the traction piece 23, namely, the part, close to the outermost part, of the traction piece 23 can be expanded and propped at the outermost part, so that the friction force between the outermost part and the groove wall of the containing groove 211 is further increased, slipping can be further prevented, the traction piece 23 can be further moved to overcome larger threading pushing resistance, invalid slipping caused by overlarge threading resistance is avoided, the threading equipment 10 can be applied to a construction environment with overlarge threading resistance caused by overlarge threading track.

It should be noted that, when the second turntable 22 rotates in this direction, the traction member 23 gradually retracts into the housing 1 and winds up on the second turntable 22. In this rotational direction, the clutch mechanism 31 is unlocked, i.e. the clutch mechanism 31 releases the locking of the relative position of the first turntable 21 and the second turntable 22, and no driving, linkage or other torque transmission means exists between the first turntable 21 and the second turntable 22 in the rotational direction.

It should be noted that if the traction element is made of a material having a certain self-resetting capability, such as metal, plastic or other materials in the prior art, the traction element may be provided with the self-resetting capability by a design on the structural profile. In the unwinding process, the traction piece with the self-resetting trend keeps a certain self-unwinding trend even in a winding state, the part of the traction piece, which is positioned on the outer ring, is always extruded by the inner ring part, namely the inner ring and the outer ring have the expanding trend due to the self-unwinding trend, but the outer ring is limited by the groove wall of the storage groove 211, and the inner ring is limited by the outer ring, so that the inner ring can form a supporting force towards the groove wall of the storage groove 211;

therefore, when the unwinding resistance is too high and the clamping stagnation is caused, the outer ring portion of the traction member in the accommodating groove 211 is further self-unwound and tightly supported on the groove wall of the accommodating groove 211, and the inner ring portion is also supported on the outer ring portion, so that the interaction force between the outer ring and the accommodating groove 211 is increased, the friction force between the outer ring and the groove wall is increased, and the traction member is ensured to be capable of continuously unwinding.

Referring to fig. 4 and fig. 5, in the process of rolling rotation, the first turntable 21 is not driven by the second turntable 22 to rotate, and the second turntable 22 drives the end of the traction element 23 to rotate continuously in the process of rolling rotation, so that the traction element 23 is rolled up on the second turntable 22 continuously, and the rolled traction element 23 is also received in the receiving slot 211.

In the rolling and rotating process, the traction piece 23 has a certain degree of unreeling, so after the traction piece 23 is received in the receiving groove 211, the traction piece 23 can approach and receive the outer groove wall of the groove 211 in the unreeling trend of the traction piece, and then, along with gradual accumulation of the number of rolling turns, the part, close to the traction piece 23, of the outer groove wall of the receiving groove 211 can be gradually separated from the groove wall for gathering, so that the part, which subsequently enters the receiving groove 211, of the traction piece 23 can be always rolled from the outermost ring, and overlapping between different ring layers of the traction piece 23 is avoided.

In addition to the above, the locking manner of the clutch mechanism 31 of the present embodiment includes: first, the clutch mechanism 31 is configured such that upon unreeling rotation of the second turntable 22, the clutch mechanism 31 immediately locks the relative positions of the first turntable 21 and the second turntable 22; second, the clutch mechanism 31 locks the relative positions of the first turntable 21 and the second turntable 22 when the second turntable 22 is unreeled to a certain specific position or positions, and keeps locked during the subsequent unreeled rotation.

Similarly, the unlocking of the clutch mechanism 31 may be configured such that the clutch mechanism 31 is unlocked immediately upon the second turntable 22 being wound and rotated; or the second turntable 22 is configured to be rolled and rotated to a certain position or a plurality of specific positions, the clutch mechanism 31 is unlocked.

Further, a guide channel may be added to the housing 1, and the guide channel corresponds to the outer groove wall of the storage groove 211, so that the guide traction member 23 can be preferentially wound and unwound from the outer groove wall edge of the storage groove 211. The outer groove wall of the storage groove 211 is a groove wall of the storage groove 211 at a position away from the center of the first turntable 21.

Further, a limiting structure is arranged at the notch of the accommodating groove 211, and is matched with the accommodating groove 211 to form a cavity together with the accommodating groove 211, so that the traction piece 23 is prevented from being directly separated from the notch of the accommodating groove 211, and the traction piece 23 is always limited in the accommodating groove 211.

Further, the limiting structure may be configured as an inner housing 11 as shown in fig. 3 to 6, the inner housing 11 is disposed in the housing 1, the rotating device 2 is disposed in the inner housing 11, and the inner housing 11 shields the accommodating groove 211, so that the inner housing 11 and the accommodating groove 211 together define a space for accommodating the traction member 23. Of course, the inner case 11 may be configured to be integrally provided to the case 1.

Specifically, the accommodating groove 211 may be configured as a groove body directly opened on the first turntable 21, or may be configured to be defined by a protrusion structure provided on the first turntable 21, as long as the traction member 23 can be effectively accommodated.

In particular, the rotating device 2 may also be configured to comprise a motor 25, the motor 25 being arranged on the housing 1 book, the motor 25 being drivingly connected to the second turntable 22. In other embodiments, the second turntable 22 may also be driven to rotate by a pneumatic power element or a hydraulic power element.

As shown in fig. 3 and 4, in some embodiments of the threading device 10, the clutch 3 further comprises at least one-way locking mechanism 32 (one-way locking mechanism 32 is shown in fig. 3), and the one-way locking mechanism 32 may be configured to be disposed between the first dial 21 and the housing 1. The unidirectional locking mechanism 32 is unlocked in the unreeling rotation direction of the second turntable 22, and the unidirectional locking mechanism 32 locks the relative positions of the first turntable 21 and the housing 1 in the reeling rotation direction of the second turntable 22.

It can be appreciated that the friction between the first rotating discs 21 and the second rotating discs 22 may cause the first rotating discs 21 to rotate in the winding direction, but the unidirectional locking mechanism 32 can prevent the first rotating discs 21 from being driven during the winding rotation of the second rotating discs 22, i.e. the second rotating discs 22 will not drive the first rotating discs 21 to rotate during the winding rotation, thus ensuring the smooth winding of the traction member 23.

The one-way locking mechanism 32 may be configured such that upon rotation of the first rotary table 21 in the winding rotation direction, the one-way locking mechanism 32 locks the position of the first rotary table 21 within the housing 1 immediately so that the first rotary table 21 stops rotating in the unwinding rotation direction. The unidirectional locking mechanism 32 may also be configured such that the unidirectional locking mechanism 32 only locks the first turntable 21 when the first turntable 21 is rotated to a certain position or positions. Similarly, unlocking of the unidirectional locking mechanism 32 may also be configured to unlock immediately or delayed unlocking after a certain angle of rotation.

As shown in fig. 8 and 9, in some embodiments of the threading device 10, the unidirectional locking mechanism 32 includes a supporting component 321 and a limiting structure 322, one of the supporting component 321 and the limiting structure 322 is disposed on the first turntable 21, and the other of the supporting component 321 and the limiting structure 322 is disposed on the housing 1;

when the first turntable 21 rotates along the unreeling direction of the second turntable 22, the propping assembly 321 slides over the limiting structure 322; when the first turntable 21 rotates along the winding rotation direction of the second turntable 22, the propping assembly 321 is propped against the limiting structure 322, so that the relative position of the first turntable 21 and the shell 1 is locked.

It is understood that the number of the propping assemblies 321 may be configured as one or more, the number of the limiting structures 322 may be configured as one or more, and the number of the propping assemblies 321 may be configured as equal to or different from the number of the limiting structures 322.

In the process of rotating the first turntable 21 along the unreeling direction of the second turntable 22, the propping assembly 321 is aligned with the limiting structure 322, but the propping assembly 321 is not clamped with each other, and the propping assembly 321 can surpass the limiting structure 322, so that the first turntable 21 can continue to rotate. And in the process of rotating the first turntable 21 along the winding direction of the second turntable 22, once the propping component 321 is aligned with the limiting structure 322, the propping component 321 is clamped with the limiting structure 322.

It should be noted that overrunning as used herein means being capable of sliding relative to each other, and that there is no torque transmitting relationship between the components.

As shown in fig. 8 and 9, in some embodiments of the threading device 10, the propping assembly 321 includes a slider 3211 and an elastic member 3212 drivingly connected to the slider 3211, where the slider 3211 corresponds to the limiting structure 322;

the limiting structure 322 is arranged on the shell 1, the sliding block 3211 and the elastic piece 3212 are both arranged on the first rotary table 21, and the elastic piece 3212 drives the sliding block 3211 to move in a direction away from the first rotary table 21; or the limiting structure 322 is arranged on the first turntable 21, the sliding block 3211 and the elastic piece 3212 are both arranged on the shell 1, and the elastic piece 3212 drives the sliding block 3211 to move towards the direction close to the first turntable 21.

It will be appreciated that when the first turntable 21 rotates in the unwinding direction of the second turntable 22, the slider 3211 is driven by the elastic member 3212 to contact the limiting structure 322, but the slider 3211 and the limiting structure 322 are not clamped with each other.

When the first turntable 21 rotates towards the winding direction of the second turntable 22, the sliding block 3211 is correspondingly clamped onto the limiting structure 322 under the driving of the elastic piece 3212, and after clamping, the relative position of the shell 1 and the first turntable 21 can be clamped.

In particular, the spring member 3212 may be configured as a spring or other component or structure capable of providing a spring force as known in the art.

Specifically, referring to fig. 8 and 9, the limiting structure 322 includes a limiting groove or limiting protrusion 3221. It will be appreciated that during the winding rotation, the hold-down assembly 321 will not grip each other in this rotational direction, although it will fall into the limit groove or contact the limit projection 3221. In the process of winding and rotating, the propping assembly 321 falls into the groove to be clamped or propped against the surface of the limiting protrusion 3221 to be clamped.

As shown in fig. 3 to 6, in some embodiments of the threading device 10, the rotating means 2 further comprise a plurality of rolling elements 26 (the rolling elements 26 can also be seen in fig. 8) for supporting the first rotary disk 21 for rotation within the housing 1; the arrangement positions of the rolling elements 26 are at least two embodiments: first, each rolling element 26 is disposed on the housing, and each rolling element 26 abuts against the first rotating disc 21; second, each rolling element 26 is disposed on the first turntable 21.

It will be appreciated that the arrangement of the rolling elements 26 changes the friction between the first turntable 21 and the housing 1 from sliding friction to rolling friction, effectively reducing wear and further improving the service life of the product.

As shown in fig. 9, in some embodiments of the threading device 10, the groove width W1 of the receiving groove 211 corresponds to the width W2 of the traction member 23; and/or the outer groove wall of the receiving groove 211 is provided with a friction ring 24 (the friction ring 24 is shown in fig. 3, 4, 5, 7 and 9).

As can be appreciated, the groove width W1 of the receiving groove 211 corresponds to the width W2 of the traction member 23, and includes: w1 is equal to W2, or W2 is slightly greater than W1. In this way, the traction members can be only received in the receiving slot 211 in a single-row overlapping manner, that is, the portions with different turns on the traction members 23 cannot be placed in the receiving slot 211 side by side, so that the traction members 23 can complete winding and unwinding one by one in a single-layer winding manner in the winding and unwinding process, overlapping or crossing among the portions with different turns on the traction members 23 is avoided, and thus the traction members 23 are prevented from being blocked in the subsequent unwinding process.

It will also be appreciated that the provision of the friction ring 24 increases the friction between the traction member 23 and the outer side groove wall of the receiving groove 211, thereby further preventing the outer most ring portion of the traction member 23 from slipping on the outer side groove wall of the receiving groove.

Specifically, the traction member is a metal belt.

When the second turntable 22 winds and rotates, the clutch movable assembly 311 is not clamped with the clutch structure 312, so that the second turntable 22 cannot drive the first turntable 21 to rotate through the clutch mechanism 31. When the second turntable 22 unwinds and rotates, the clutch movable assembly 311 will correspondingly clamp the clutch structure 312, so that the first turntable 21 can drive the second turntable 22 to rotate together.

As shown in fig. 8 and 9, in some embodiments of the threading device 10, the clutch movable assembly 311 includes a clutch plate 3111 and a clutch elastic member 3112 drivingly connected to the clutch plate 3111, wherein the clutch plate 3111 corresponds to the clutch structure 312;
