Detailed Description

The following description provides specific applications and requirements of the application to enable any person skilled in the art to make and use the application. Various modifications to the disclosed embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments and applications without departing from the spirit and scope of the application. Thus, the present application is not limited to the embodiments shown, but is to be accorded the widest scope consistent with the claims.

In general, a wire takeup, also called a hover device, is required for a gas station, a charging station, or the like, and can be used for balancing the gravity of a fuel line of a fuel dispenser in the gas station or a cable of a charging pile (hereinafter, collectively referred to as a "pipeline") in the charging station, hovering the pipeline in the air, automatically retracting the pipeline, or the like. Specifically, the wire takeup device may include a housing, and a spring case (which may also be referred to as a "drum") and a wire rope received in the housing, one end of the wire rope being fixedly connected to the pipeline, the other end being wound around the spring case, a coil spring being provided in the spring case, the coil spring being provided around a central axis. When the staff pulls the pipeline, can drive the one end that wire rope and pipeline are connected along staff's pulling direction motion for wire rope twines the part on the spring case and releases from the spring case, drives the spring case and rotates around the center pin, and the wind spring in the spring case can take place to warp simultaneously (for example inwards shrink), makes the wind spring have pulling force to the wire rope, and this pulling force can be used for balancing the gravity of pipeline, makes the pipeline hover in the sky, and the staff just need not carry out the operation of stable pipeline when using the pipeline, thereby has alleviateed staff's intensity of labour. In addition, in the process of pulling out and withdrawing the pipeline, the steel wire rope can pull the pipeline to enable the pipeline to be in a suspended state all the time, so that the pipeline is prevented from being damaged due to contact with the ground, and potential safety hazards are avoided.

However, most wire retractors currently cannot adapt to pipelines with different weights, when the weight of the pipeline connected with the wire rope in the wire retractor changes, the initial tension of the wire retractor to the wire rope may not balance the gravity of the pipeline, but the pipeline cannot be hovered at the initial position, for example, when the wire rope of the wire retractor is connected with a pipeline with larger weight, the tension of the wire rope to the wire retractor is insufficient to balance the gravity of the pipeline, so that the pipeline cannot hover at the initial position without being pulled, and the situation that the pipeline falls into contact with the ground to cause pollution occurs.

The embodiment of the application provides a wire winder, which comprises: a housing comprising a shell and a bottom plate; the central shaft is arranged in the shell, and the first end of the central shaft is rotatably arranged on the bottom plate; the second end of the central shaft protrudes out of the upper surface of the shell, and is provided with an adjusting plate which is fixedly connected with the upper surface of the shell through a screw; wherein, the second end of the central shaft is provided with at least one flat position, and the adjusting plate is provided with an assembly hole which is matched with the shape of the second end of the central shaft; the rotary drum is positioned in the shell, sleeved on the central shaft and can rotate around the central shaft; the inner end of the coil spring is fixedly connected with the central shaft, and the outer end of the coil spring is fixed in the rotary drum; and when the other end of the wire is pulled, the rotating drum can be driven to rotate. The initial tension of the coil spring to the winding wire in the winding machine provided by the embodiment of the application is adjustable, so that the winding machine can be adapted to target objects with different weights. Specifically, the operator can adjust the tension provided by the coil spring to the winding wire according to the weight of the target object connected with the other end of the winding wire, so that the tension provided by the coil spring to the winding wire can balance the gravity of the target object, and therefore, the target object can be hovered at the initial position when the target object is not pulled, and the condition that the target object cannot be hovered at the initial position to cause the falling of the target object to contact with the ground to cause pollution or abnormal use is avoided. It should be noted that, the target object in the embodiment of the present application may refer to a cable of a charging pile in a charging station and an oil pipe of an oil filling machine in a gas station, and may also be other objects that need to balance gravity, hover and automatically retract. In addition, the winding and pulling wire in the embodiment of the application can be a steel wire rope or other wires, and the application is not limited.

The technical scheme of the application is described in detail below with reference to the examples and the accompanying drawings.

Fig. 2 is a schematic diagram of a structure of a wire takeup according to some embodiments of the present application after a portion of the wire takeup is cut away.

As shown in fig. 1 to 5, the wire takeup device 100 according to the embodiment of the present application may include a housing 110, a central shaft 120, a drum 130, and a wire takeup wire 140. Wherein the housing 110 includes a case 111 and a bottom plate 112, and the case 111 is mounted on the bottom plate 112 to form the housing 110. The central shaft 120 is disposed in the housing 110, and a first end of the central shaft 120 is rotatably mounted on the bottom plate 112; the second end of the central shaft 120 protrudes from the upper surface of the housing 110, and the second end of the central shaft 120 is provided with an adjusting plate 170, and the adjusting plate 170 is fixedly connected with the upper surface of the housing 110 by a screw; wherein, the second end of the central shaft is provided with at least one flat 122, and the adjusting plate 170 is provided with an assembly hole 171 adapted to the shape of the second end of the central shaft 120. The rotary drum 130 is located in the housing 110 and sleeved on the central shaft 120, and can rotate around the central shaft 120; the drum 130 is provided with a coil spring 131 therein, the coil spring 131 is disposed around the central shaft 120, an inner end 1311 of the coil spring 131 is fixedly connected with the central shaft 120, and an outer end 1312 of the coil spring 131 is fixed inside the drum 130. One end of the pullout wire 140 is fixedly connected to the drum 130 and wound around the drum 130 in a first direction, and the other end passes through the housing 110 to be positioned outside the housing 110 to be connected to a target object (not shown) to be retracted and pulled out. It should be noted that the first direction in the embodiment of the present application may refer to a rotation direction about the central axis 120 as a rotation center, for example, the first direction in the embodiment of the present application may be a counterclockwise direction in fig. 1, 2 and 4, that is, a clockwise direction in fig. 3.

The operation mechanism of the wire takeup 100 will be exemplarily described below in conjunction with the structure of the wire takeup 100.

As an exemplary description, when a worker pulls out a target object, that is, pulls the other end of the pull wire 140 to move in a direction away from the inside of the housing 110 (that is, the other end of the pull wire 140 is pulled out), another portion wound on the drum 130 is released from the drum 130 to rotate the drum 130 in a first direction, since the outer end 1312 of the coil spring 131 is fixedly connected to the inner side wall of the drum 130, the drum 130 rotates in the first direction to drive the outer end 1312 of the coil spring 131 to rotate in the first direction, the inner end 1311 of the coil spring 131 is kept stationary, such that the coil spring 131 is elastically deformed to twist in a bending direction in a plane, and is embodied as radially expanding deformation or contracting deformation of the coil spring 131, for example, as shown in fig. 4, the winding direction of the coil spring 131 around the central shaft 120 is a second direction (clockwise direction in fig. 4), and when the outer end 1312 of the coil spring 131 rotates in the first direction, the coil spring 131 is radially expanding deformed to generate an elastic force acting on the drum 130 to be provided to the pull wire 140, and the pull force F1 can stop pulling the other end 140 to rotate in the direction of the other end of the pull wire 140 to make the coil spring 131 to move toward the inside of the housing 110 (that is retracted in the other end of the housing) opposite to the direction). Wherein the frictional force generated by the relative movement between the components in the wire takeup 100 (e.g., the wire takeup 140 and the drum 130, the drum 130 and the central shaft 120, etc.) is f.

In the wire rewinding machine 100 provided in the embodiment of the application, the second end of the central shaft 120 is installed in the installation hole 171 of the adjusting plate 170, and then the adjusting plate 170 is fixed with the upper surface of the casing 110 by a screw, so that the rotation of the drum 130 drives the central shaft 120 to rotate in the process of pulling out or retracting the other end of the winding wire 140, and the rotation of the central shaft 120 changes the position of the inner end 1311 of the coil spring 131, so that the tension provided by the coil spring 131 to the winding wire 140 is changed, and the smoothness and the feel of the other end of the winding wire 140 pulled out or retracted by a worker are affected.

In some embodiments, to ensure that the wire takeup 100 can adapt to target objects of different weights, that is, when the other end of the wire takeup 140 of the wire takeup 100 is connected to a target object of different weight, the target object of different weight can be suspended by the wire takeup 100 in the initial position without falling off without being pulled, a worker can adjust the tension provided to the wire takeup 140 by the coil spring 131 according to the weight of the target object connected to the other end of the wire takeup 140, so that the tension provided to the wire takeup 140 by the coil spring 131 can balance the gravity of the target object, and thus the target object can be suspended in its initial position when the target object is not pulled. Specifically, before pulling the target object, the target operator can rotate the central shaft 120 together by rotating the adjusting plate 170, so as to adjust the position of the inner end 1312 of the coil spring 131, thereby achieving the purpose of adjusting the initial tension of the coil spring 131 provided to the winding wire 140, ensuring that the winding machine 100 can adapt to target objects with different weights, and avoiding the situation that when the other end of the winding wire 140 is connected with a target object with larger weight, the initial tension of the coil spring provided to the winding wire is insufficient to balance the gravity of the target object, so that the target object cannot hover at the initial position of the target object without being pulled, and falls to contact with the ground to cause the occurrence of fouling.

As an exemplary illustration, when the target object connected to the other end of the wire takeup 140 of the wire takeup 100 is replaced with a target object of a different weight, a worker may detach the screw connecting the upper surface of the housing 110 and the adjustment plate 170 such that the adjustment plate 170 is not fixed to the upper surface of the housing 110, then rotate the adjustment plate 170 such that the central shaft 120 rotates to rotate the inner end 1312 of the coil spring 131 to a predetermined position, and then fixedly connect the adjustment plate 170 to the upper surface of the housing 110 by the screw, thereby allowing the tension provided by the coil spring 131 to the wire takeup 140 to balance the gravity of the replaced target object, thereby allowing the wire takeup 100 to be adapted to the replaced target object.

In some embodiments, to enable the first end of the central shaft 120 to be rotatably mounted to the base plate 112, the base plate 112 may be provided with a mounting hole adapted to the shape of the first end of the central shaft 120, and the first end of the central shaft 120 may be rotatably mounted to the base plate 112 by the first end of the central shaft 120 being positioned in the mounting hole. The second end of the central shaft 120 may be a cylinder or other solid of revolution.

In some embodiments, in order to reduce friction between the first end of the central shaft 120 and the mounting hole on the bottom plate 112, so that the central shaft 120 can smoothly rotate when a worker rotates the adjustment plate 170, the operation burden of the worker is reduced, a bearing (not shown in the drawings) may be disposed between the first end of the central shaft 120 and the mounting hole, wherein an outer ring of the bearing is fixed to an inner wall of the mounting hole, and an inner ring of the bearing is fixed to the first end of the central shaft 120. By providing a bearing between the first end of the central shaft 120 and the mounting hole on the bottom plate 112, not only can the friction between the first end of the central shaft 120 and the mounting hole on the bottom plate 112 be reduced, but also the wear of the first end of the central shaft 120 can be reduced, and the service life of the central shaft 120 can be prolonged.

In some embodiments, in order to enable the adjustment plate 170 to be fixedly connected with the upper surface of the housing 110 through screws, a plurality of through holes 172 may be provided on the adjustment plate 170, the plurality of through holes 172 may be distributed in an annular array around the axis of the assembly hole 171, correspondingly, the upper surface of the housing 110 may be provided with threaded connection holes corresponding to the plurality of through holes 172, and the screws may pass through the through holes 172 to be in threaded connection with the corresponding threaded connection holes on the upper surface of the housing 110, so as to achieve the fixed connection between the adjustment plate 170 and the upper surface of the housing 110. In this embodiment, in order to ensure that all the through holes 172 can correspond to the threaded connection holes on the upper surface of the housing 110 after the adjustment plate 170 rotates so that the screws can pass through the through holes 172 to be in threaded connection with the threaded connection holes, the angle of each rotation of the adjustment plate 170 should be n times (n=0, 1, 2, 3 … …) the included angle between the connecting lines of the centers of the adjacent two through holes 172 and the center of the assembly hole 171. Note that the number of through holes 172 shown in fig. 1 is merely an example, and the number of through holes 172 may be four as shown in fig. 1, or may be two, three, five, six, or the like. In some embodiments, the greater the number of through holes 172 on the adjustment plate 170, the smaller the angle between the lines connecting the centers of the adjacent two through holes 172 to the center of the fitting hole 171, the smaller the minimum angle the adjustment plate 170 can rotate at a time, and the greater the accuracy of the tension adjustment provided to the retractor wire 140 by the coil spring 131.

In some embodiments, in order to facilitate the rotation of the adjustment plate 170 by a worker, as shown in fig. 1, at least two tool connection holes 172 are further provided on the adjustment plate 170, and the at least two tool connection holes 172 may be symmetrically distributed about the axis of the assembly hole 171. By providing at least two tool connection holes 172, corresponding rotating tools can be connected, and a worker can rotate the adjustment plate 170 by operating the rotating tools, so that the adjustment plate 170 can be easily rotated by a certain angle with less operation load. In some embodiments, the number of tooling connection holes 172 may be four as shown in fig. 1, or may be three, five, six, etc.

In some embodiments, in order to facilitate the rotation of the adjustment plate 170 by a worker, as shown in fig. 1, at least two tool connection holes 172 are further provided on the adjustment plate 170, and the at least two tool connection holes 172 may be symmetrically distributed about the axis of the assembly hole 171. By providing at least two tool connection holes 172, corresponding rotating tools can be connected, and a worker can rotate the adjustment plate 170 by operating the rotating tools, so that the adjustment plate 170 can be easily rotated by a certain angle with less operation load. In some embodiments, the number of tooling connection holes 172 may be four as shown in fig. 1, or may be three, five, six, etc.

Fig. 6 is a schematic structural diagram of a rotating tool according to some embodiments of the present application. Fig. 7 is a schematic diagram illustrating connection between a rotating tool and a wire takeup according to some embodiments of the present application.

As shown in fig. 6 and 7, the embodiment of the present application further provides a rotating tool 200 for rotating the adjusting plate 170, and the rotating tool 200 may include a handle 210 and a connection head 220 provided at one end of the handle 210, wherein at least two connection posts 221 corresponding to at least two tool connection holes 173 on the adjusting plate 170 are provided on the connection head 220, and the at least two connection posts 221 may be used to be inserted into the at least two tool connection holes 173. As an exemplary description, when a worker rotates the adjustment plate 170 using the rotating tool 200, the worker may insert the connection posts into the work connection holes correspondingly, and then rotate the handle 210 to rotate the adjustment plate 170. Wherein, by arranging at least two tool connection holes 173 symmetrically distributed about the axis of the assembly hole 171 and then inserting at least two connection posts 221 into at least two tool connection holes 173, it is fully ensured that a worker can drive the adjustment plate 170 to rotate together when rotating the handle 210.

In some embodiments, at least one bearing may be disposed between the drum 130 and the central shaft 120, so that noise generated when the drum 130 rotates around the central shaft 120 may be reduced, and friction between the drum 130 and the central shaft 120 may be effectively reduced, so that the friction may be reduced to twenty percent, and a worker may easily pull the target object, and ensure that the worker has better operation experience and feel by the smooth pulling and retracting process of the target object. In addition, the bearing can avoid the situation that the central shaft 120 is inclined due to abrasion between the drum 130 and the central shaft 120 after the wire takeup device 100 is used for a long time, so that the drum 130 is inclined to contact with the shell 110 to generate friction when rotating, and the other end (namely a target object) of the wire takeup 140 is difficult to pull, and even the drum 130 is blocked with the shell 110, and the other end of the wire takeup 140 cannot be pulled.

The following will describe in further detail how the wire takeup 100 allows a worker to have a better feel when pulling a target object.

When the worker pulls the other end of the pull wire 140, the pulling force F2 (the direction of F2 is opposite to the direction of F1) applied by the worker to the other end of the pull wire 140 (or the target object) needs to satisfy F2> f1+f, and the reaction force of the other end of the pull wire 140 to the worker is F2; when the target object (i.e. the other end of the wire 140) is kept stationary, the other end of the wire 140 has a retracting tendency, and the pulling force f3=f1-F (F3 is opposite to F1) applied by the worker to the wire 140, and the reaction force of the other end of the wire 140 to the worker is F3. Thus, F2-F3>2F is available.

Further, in the actual use process of the wire rewinding machine 100, the operator pulls the target object to drive the other end of the rewinding wire 130 to be pulled out, and the other end of the rewinding wire 140 will have a tendency to be pulled out for a while because the pulling force applied by the operator on the target object is not uniform and continuous, and the other end of the rewinding wire 140 will be frequently switched between the two states for a while, so that the reaction force of the other end of the rewinding wire 140 to the operator will be suddenly changed between F2 and F3. According to F2-F3>2F, if the friction force F generated by the relative movement between the components in the wire takeup device 100 is larger, the operator pulls the other end of the wire takeup 140, and the reaction force of the other end of the wire takeup 140 to the operator jumps in a larger range, so that the operator feel is poor. In the wire takeup device 100 provided in the embodiment of the present application, by providing at least one bearing (for example, the first bearing 151 and the second bearing 152 shown in fig. 2) between the drum 130 and the central shaft 120, friction force between the drum 130 and the central shaft 120 can be reduced, so that friction force f generated by relative movement between each component in the wire takeup device 100 during pulling out and retracting of the target object is reduced, and when a worker pulls the other end of the wire takeup wire 140, the reaction force of the other end of the wire takeup wire 140 to the worker can jump in a smaller range, thereby ensuring that the worker has better hand feeling.

Further, the bearing disposed between the drum 130 and the central shaft 120 may include an outer ring (e.g., a first outer ring 1511 and a second outer ring 1521 shown in fig. 2), an inner ring (e.g., a first inner ring 1512 and a second inner ring 1522 shown in fig. 2), and a rolling body (e.g., a first rolling body 1513 shown in fig. 2) disposed between the outer ring and the inner ring, wherein an inner ring is sleeved on the central shaft 120 and fixed with the central shaft 120, the outer ring is fixed with the drum 130, when the drum 130 rotates around the central shaft 120, the outer ring rotates relative to the inner ring, the rolling body rolls between the inner ring and the outer ring, so that friction between the outer ring and the inner ring is rolling friction, the friction force of rolling friction is small, and the friction force f generated by relative movement between each component in the wire collector 100 during pulling out and retracting of a target object can be reduced, so that when a worker pulls the other end of the wire collector 140, the other end of the wire collector 140 can bounce to the worker in a small range, and the worker can feel better. In some embodiments, the rolling bodies may be balls, cylindrical rollers, tapered rollers, needle rollers, and the like.

In some embodiments, as shown in fig. 2, at least one bearing disposed between the drum 130 and the central shaft 120 may include a first bearing 151 and a second bearing 152, and the first bearing 151 and the second bearing 152 may be sequentially disposed between the drum 130 and the central shaft 120 in an axial direction of the drum 130. Wherein the first bearing 151 includes a first outer race 1511, a first inner race 1512, and first rolling bodies 1513 disposed between the first outer race 1511 and the first inner race 1512; the second bearing 152 includes a second outer ring 1521, a second inner ring 1522, and second rolling bodies 1523 disposed between the second outer ring 1521 and the second inner ring 1522. As an exemplary illustration, the upper and lower surfaces of the drum 130 are provided with a first bearing mount 132 and a second bearing mount 133, respectively, and a first bearing 151 and a second bearing 152 are mounted within the first bearing mount 132 and the second bearing mount 133, respectively. The first and second inner rings 1512, 1522 are fixed to the central shaft 120, and the first and second outer rings 1511, 1521 are fixed to the first and second bearing mounts 132, 133, respectively.

In some embodiments, referring to fig. 3, the wire takeup 100 may further include a detent structure 160, where the detent structure 160 may be used to limit the drum 130 from continuing to rotate when the worker pulls the target object out to the desired position, thereby enabling the target object to hover at the desired position, facilitating the worker's use or operation of the target object, and eliminating the need for additional actions by the worker to stabilize the target object at the desired position, thereby reducing the worker's work intensity. Specifically, the clamping structure 160 includes a clamping block 161, a U-shaped spring 162, and at least one limiting block 163; the clamping block 161 and the U-shaped spring 162 are jointly arranged on the lower surface of the rotary drum 130, at least one limiting block 163 is fixedly arranged on one side, close to the clamping block 161, of the housing 119 (namely, the upper surface of the bottom plate 112, namely, the surface, facing the rotary drum 130, of the bottom plate 112), and when the clamping block 161 is matched with the limiting block 163, the rotary drum 130 cannot rotate.

Further, the stopper 163 has a blocking portion 1631 thereon; the clamping block 161 comprises a connecting end 1611 and a free end 1612, a connecting shaft 134 rotatably connected with the connecting end 1611 is arranged on the lower surface of the rotary drum 130, and the connecting end 1611 is clamped in the U-shaped spring 162. In some embodiments, the clamping block 161, the U-shaped spring 162 and the connecting shaft 132 may also be disposed on the upper surface of the drum 130 together, and correspondingly, at least one limiting block 163 is fixedly mounted on a surface of the housing 111 near the drum 130.

As an exemplary illustration, when the operator pulls the other end of the wire 140, the portion of the wire 140 wound around the drum 130 is released from the drum 130 to rotate the drum in the first direction, the coil spring 131 is deformed by shrinkage to generate an elastic force, when the other end of the wire 140 (i.e., the target object) reaches the desired position, the operator may stop pulling the other end of the wire 140, the coil spring 131 is deformed by restoration, the drum 130 rotates in the second direction under the elastic force of the coil spring 131, and drives the latch 161 to rotate in the second direction, so that the free end 1612 of the latch 161 interferes with the blocking portion 1631 of the stopper 163 when the latch 161 passes the stopper 163, and abuts against the blocking portion 1631, thereby limiting the drum 130 to continue rotating in the second direction, so that the target object hovers in the desired position.

When the other end (i.e., the target object) of the wire 140 needs to be retracted, the worker can pull the other end of the wire 140 by pulling the target object in the hovering state again, and then the clamping block 161 rotates around the connecting shaft 134 under the elastic force of the U-shaped spring 162, so that the free end of the clamping block 161 is not interfered with the blocking portion 1631, and after the worker stops pulling the other end of the wire 140, the blocking portion 1631 is not blocked to the rotation of the clamping block 161, so that the drum 130 can continue to rotate along the second direction, and the purpose of retracting the other end (i.e., the target object) of the wire 140 can be achieved.

The rigidity of the housing 110 and the drum 130 in the embodiment of the present application is not too high, and even if the rigidity of the housing 110 and the drum 130 is not too high, the functional requirement that the housing 110 and the drum 130 limit the drum 130 to continue rotating can be met by the detent structure 160, so in some embodiments, the housing 110 and the drum 130 can be formed by casting, and the functional requirement that the drum 130 limit the drum 130 to continue rotating can be met by the rigidity of the housing 110 and the drum 130 formed by casting, and the casting cost is low, so that the production cost of the wire winder 100 can be reduced.

In some embodiments, as shown in fig. 5, the housing 111 may include a top plate 1111 and a side plate 1112, and a plurality of hollow holes 114 may be formed on the top plate 1111 and/or the side plate 1112, and by forming the hollow holes 114 on the top plate 1111 and/or the side plate 1112, redundancy in manufacturing materials of the housing 111 may be avoided, which may result in higher production cost. In addition, by providing the hollowed holes 114, the weight of the housing 111 can be reduced, so that the weight of the whole wire rewinding machine 100 can be reduced, and the wire rewinding machine 100 is convenient to transport, install and use. In some embodiments, the top panel 1111 and the side panel 1112 may be an integrally formed structure, for example, the top panel 1111 and the side panel 1112 may be integrally formed by casting or the like. In some embodiments, the top plate 1111 and the side plate 1112 may be formed as a separate structure, and then connected by welding, screwing, or the like to form the housing 111.

In some embodiments, the number of the hollowed holes 114 of the top plate 1111 and/or the side plate 1112 may be 2-8, which may substantially reduce the materials used in manufacturing the housing 111, reduce the production cost, and effectively reduce the weight of the housing 111, so as to facilitate transportation, installation and use of the wire rewinding device 100. Preferably, as shown in fig. 5, the number of the hollowed holes 114 on the top plate 1111 and/or the side plate 1112 may be 4, so that the top plate 1111 and/or the side plate 1112 can be ensured to have better structural strength while the materials used for manufacturing the housing 111 and the weight of the housing 111 are reduced, so that the housing 111 is not damaged easily, and has a longer service life.

In some embodiments, as shown in fig. 5, the plurality of hollowed holes 114 on the top plate 1111 may be symmetrically distributed about the axis of the central shaft 120, so that the top plate 1111 may have better structural strength. In some embodiments, the area of the hollowed-out hole 114 on the top plate 1111 may be 0.5 to 0.85, so that the weight of the top plate 1111 is reduced, the material is used, and the top plate 1111 has better structural strength.

In some embodiments, as shown in fig. 5, the plurality of hollowed holes 114 on the side plate 1112 may be distributed on the side plate 1112 at equal intervals around the axis of the central shaft 120, so that the side plate 1112 can be ensured to have better structural strength. In some embodiments, the area ratio of the hollow holes 114 on the side plate 1112 may be 0.5 to 0.9, so that the weight of the side plate 1112 is reduced and the material is used, and the side plate 1112 can have better structural strength.

In some embodiments, the other end of the wire 140 may be located outside the housing 110 through the hollow hole 114 on the side plate 1112. In some embodiments, as shown in fig. 1 and 5, when the wire winding 140 in the wire winding device 100 is wound on the drum 130 along the first direction, the other end of the wire winding 140 may be threaded out from the hollow hole 114 on the left side of the side plate 1112, i.e. the wire winding device 100 is wire-out from the left side. In some embodiments, the left and right sides of the side plate 1112 may each have a hollowed-out hole 114. When the wire winding 140 in the wire winding device 100 is wound on the drum 130 along the second direction, the other end of the wire winding 140 can be threaded out from the hollow hole 114 on the right side of the side plate 1112, i.e. the wire winding device 100 is wire-led out from the right side. Through making curb plate 1112 both sides all have fretwork hole 114, can make casing 111 can satisfy the demand of two kinds of service scenarios of spooler 100 from left side outgoing line and from right side outgoing line simultaneously, spooler 100 under two kinds of service scenarios can share a casing 111, so can reduce the die sinking cost and the material cost of manufacturing casing 111.

In some embodiments, as shown in fig. 4, a notch 121 may be formed on a side surface of the central shaft 120, and an inner end 1311 of the coil spring 131 may be clamped in the notch 121 to achieve relative fixation with the central shaft 120. In some embodiments, the outer end 1312 of the coil spring 131 may be secured inside the drum 130 by a screw 1313, for example, the outer end 1312 of the coil spring 131 may be fixedly attached to the inner bottom surface of the drum 130 by the screw 1313. In some embodiments, the outer end 1312 of the coil spring 131 may also be fixedly attached to the inner side wall of the drum 130 by screws. With the above arrangement, it is possible to facilitate the disassembly, installation, adjustment, or the like of the coil spring 131 by a worker.

In some embodiments, as shown in connection with fig. 1-3, the upper and/or lower surface of the drum 130 may have a plurality of radial ribs 135 thereon, the plurality of radial ribs 135 being spoke-like emission distributed from the center of the upper and/or lower surface of the drum 130 and extending to the edges of the upper and/or lower surface of the drum 130. In some embodiments, as shown in connection with fig. 1-3, the upper and/or lower surface of the drum 130 may have a plurality of circumferential ribs 136 thereon, the plurality of circumferential ribs 136 having different diameters from small to large and being concentrically distributed about the center of the upper and/or lower surface of the drum 130. By providing the upper and/or lower surfaces of the drum 130 with a plurality of radial ribs 135 and/or a plurality of circumferential ribs 136, the strength and rigidity of the drum 130 can be enhanced without increasing the wall thickness of the drum 130, thereby saving the amount of material used to manufacture the drum 130, reducing the weight of the drum 130, reducing the cost, and overcoming the distortion of the drum 130 caused by uneven stress due to uneven wall thickness of the drum 130 while ensuring a longer service life of the drum 130.
