Description

Technical Field

[0001] This application relates to the technical field of wire take-up devices, and particularly to a wire take-up device and a rotating tooling. Background Art

[0002] The wire take-up device, also known as a hovering device, is widely used in many fields. For example, the wire take-up device can be used in charging stations and gas stations. The steel wire rope in the wire take-up device can be connected to the fuel pipe of the fuel dispenser in the gas station or the cable of the charging pile in the charging station (collectively referred to as "pipelines"). The pulling force of the wire take-up device on the steel wire rope can be used to balance the gravity of the pipeline, so that the pipeline is always in a suspended state during the process of being pulled out and retracted, ensuring that the pipeline does not contact the ground, avoiding the pollution of the pipeline, and eliminating potential safety hazards. Currently, the wire take-up devices equipped in places such as charging stations and gas stations are generally heavy, which not only brings inconvenience to transportation, installation, and use, but also has a high production cost.

[0003] Therefore, how to reduce the weight and production cost of the wire take-up device is a technical problem that needs to be solved urgently at present. Summary of the Invention

[0004] One embodiment of this application provides a wire take-up device, including: a housing, the housing includes a shell and a bottom plate, the shell is installed on the bottom plate to form the housing, and a plurality of hollow holes are provided on the shell; a central shaft, the central shaft is arranged inside the housing, and the first end of the central shaft is installed on the bottom plate; a rotating cylinder, the rotating cylinder is located inside the housing and is rotatably sleeved on the central shaft; wherein, a winding spring is arranged inside the rotating cylinder, the winding spring is arranged around the central shaft, the inner end of the winding spring is fixedly connected to the central shaft, and the outer end of the winding spring is fixed inside the rotating cylinder; a take-up wire, one end of the take-up wire is fixedly connected to the rotating cylinder and is wound around the rotating cylinder in a first direction, and the other end passes through the housing and is located outside the housing.

After stopping pulling the other end of the retracting wire, the coil spring resumes deformation, and the rotating cylinder rotates in the second direction opposite to the first direction under the elastic force of the coil spring, simultaneously driving the clamping block to rotate in the second direction, such that when the clamping block passes by the limiting block, the free end of the clamping block interferes with the blocking portion of the limiting block and abuts against the blocking portion, thereby restricting the rotating cylinder from continuing to rotate in the second direction; when the other end of the retracting wire is pulled again, the clamping block rotates around the connecting shaft under the elastic force of the U-shaped spring, such that the free end of the clamping block no longer interferes with the blocking portion, so that after stopping pulling the other end of the retracting wire, the rotating cylinder can continue to rotate in the second direction.

[0026] The following description provides specific application scenarios and requirements of the present application, aiming to enable those skilled in the art to manufacture and use the content of the present application. For those skilled in the art, various local modifications to the disclosed embodiments are obvious, and the general principles defined here can be applied to other embodiments and applications without departing from the spirit and scope of the present application. Therefore, the present application is not limited to the disclosed embodiments, but has the widest scope consistent with the claims.

[0027] The oil pipes of fuel dispensers in gas stations or the cables of charging piles in charging stations (hereinafter collectively referred to as "pipelines") are generally stored in corresponding storage structures. When staff need to use the pipelines, they need to pull out the pipelines from the corresponding storage structures for operation. When the pipelines are no longer in use, they need to be retracted into the corresponding storage structures.

[0028] In places such as gas stations and charging stations, a cable retractor is generally required. A cable retractor, also known as a hover device, can be used to balance the gravity of the fuel pipe of a fuel dispenser in a gas station or the cable of a charging pile in a charging station (collectively referred to as "pipelines" hereinafter), suspend the pipeline in the air, and automatically retract the pipeline, etc. Specifically, the cable retractor can include a housing, and a spring box (also referred to as a "drum") and a steel wire rope housed in the housing. One end of the steel wire rope is fixedly connected to the pipeline, and the other end is wound around the spring box. A spiral spring is provided in the spring box, and the spiral spring is arranged around a central axis. When a staff member pulls the pipeline, it will drive one end of the steel wire rope connected to the pipeline to move along the pulling direction of the staff member, so that the part of the steel wire rope wound around the spring box is released from the spring box, driving the spring box to rotate around the central axis. At the same time, the spiral spring in the spring box will deform (for example, shrink inward), so that the spiral spring has a pulling force on the steel wire rope. This pulling force can be used to balance the gravity of the pipeline, so that the pipeline can be suspended in the air. When the staff member uses the pipeline, there is no need to perform the operation of stabilizing the pipeline, thus reducing the labor intensity of the staff member. In addition, during the process of pulling out and retracting the pipeline, the steel wire rope can hold the pipeline so that the pipeline is always in a suspended state, avoiding the pipeline from contacting the ground and being damaged, so as to eliminate potential safety hazards.

[0029] However, the housing of the cable retractor is generally completely enclosed, made of galvanized steel plate by one-piece stamping or aluminum alloy casting. The use of materials for the completely enclosed housing is redundant, which will bring a relatively high material usage cost. At the same time, the completely enclosed housing will make the cable retractor relatively heavy, bringing inconvenience to transportation, installation and use. In addition, the completely enclosed housing cannot meet the requirements of the two usage scenarios of the cable retractor for feeding out the wire from the left side and the right side at the same time. Cable retractors in the two usage scenarios require different housings, and different molds need to be opened when manufacturing the housings, which will also increase the production cost and bring inconvenience to installation and material management, etc. At the same time, the mechanism for restricting the rotation of the spring box has requirements for the stiffness of the housing of the cable retractor. In order to make the housing of the cable retractor have better stiffness, the housing of the cable retractor is generally formed by stamping, and the production cost is relatively high.

[0030] An embodiment of the present application provides a wire winder, including: a housing, which includes a housing body and a bottom plate, the housing body is installed on the bottom plate to form the housing, and a plurality of hollow holes are opened on the housing body; a central shaft, the central shaft is arranged inside the housing, and the first end of the central shaft is installed on the bottom plate; a rotating cylinder, the rotating cylinder is located inside the housing and is rotatably sleeved on the central shaft; wherein, a winding spring is arranged inside the rotating cylinder, the winding spring is arranged around the central shaft, the inner end of the winding spring is fixedly connected to the central shaft, and the outer end of the winding spring is fixed inside the rotating cylinder; a wire drawing, one end of the wire drawing is fixedly connected to the rotating cylinder and is wound around the rotating cylinder along a first direction, and the other end passes through the housing and is located outside the housing. When the pulling force received by the other end of the wire drawing exceeds a preset pulling force, the rotating cylinder rotates along the first direction; a positioning structure, the positioning structure includes a clamping block, a U-shaped spring and at least one limiting block; wherein, the clamping block and the U-shaped spring are jointly arranged on the upper surface or the lower surface of the rotating cylinder, and at least one limiting block is fixedly installed on one side of the housing close to the clamping block. When the limiting block and the clamping block are clamped, the rotation of the rotating cylinder along a second direction opposite to the first direction is restricted.

[0031] By providing a hollow structure on the housing body, the wire winder provided by the embodiment of the present application can reduce the material usage cost when manufacturing the housing body, and at the same time reduce the weight of the housing body, thereby being able to reduce the overall weight of the wire winder, making the wire winder convenient for transportation, installation and use. In addition, the hollow holes on the housing body can simultaneously meet the requirements of two usage scenarios where the other end of the wire drawing exits from the left side of the housing and exits from the right side of the housing. The wire winders in the two usage scenarios can share the same housing body, saving the mold opening cost of the housing body, thereby reducing the production cost.

[0032] At the same time, the positioning structure in the wire winder provided by the embodiment of the present application can be used to restrict the continuous rotation of the rotating cylinder when the staff pulls the target object to the expected position, so that the target object can hover at the expected position, facilitating the staff to use the target object or operate on it, enabling the staff to no longer need to use additional actions to stabilize the target object at the expected position, thereby reducing the working intensity of the staff. Moreover, the positioning structure has a low requirement for the stiffness of the housing, so the stiffness of the housing does not need to be too large. Therefore, the housing can be formed by casting, thereby reducing the production cost of the wire winder.

[0033] It should be noted that the target object in the embodiment of the present application may refer to the fuel pipe of the fuel dispenser in the gas station, the cable of the charging pile in the charging station, or other objects that need to balance gravity, hover and automatically retract. In addition, the wire drawing in the embodiment of the present application can be a steel wire rope or other wire materials, and the present application does not limit it. The technical solution of the present invention will be described in detail below with reference to the embodiments and the drawings.

Figure 2 It is a schematic diagram of the structure of the wire take-up device after removing a part of the structure shown in some embodiments of the present application. Figure 3 It is a schematic diagram of the structure of the wire take-up device after removing the bottom plate shown in some embodiments of the present application. Figure 4 It is a schematic diagram of the structure of the wire take-up device after removing the upper surface of the housing and the rotating cylinder shown in some embodiments of the present application. Figure 5 It is a schematic diagram of the structure of the housing shown in some embodiments of the present application.

[0035] As Figures 1 to 5 shown, the wire take-up device 100 provided in the embodiments of the present application may include a housing 110, a central shaft 120, a rotating cylinder 130, a take-up wire 140, and a clamping structure 160. Among them, the housing 110 includes a housing body 111 and a bottom plate 112. The housing body 111 is installed on the bottom plate 112 to form the housing 110, and a plurality of hollow holes 114 may be provided on the housing 110. The central shaft 120 is arranged inside the housing 110, and the first end of the central shaft 120 is installed on the bottom plate 112. The rotating cylinder 130 is located inside the housing 110 and is rotatably sleeved on the central shaft 120; a torsion spring 131 is arranged inside the rotating cylinder 130. The torsion spring 131 is arranged around the central shaft 120. The inner end 1311 of the torsion spring 131 is fixedly connected to the central shaft 120, and the outer end 1312 of the torsion spring 131 is fixed inside the rotating cylinder 130. One end of the take-up wire 140 is fixedly connected to the rotating cylinder 130 and is wound around the rotating cylinder 130 in a first direction, and the other end passes through the housing 110 and is located outside the housing 110 to be connected to a target object (not shown in the figure) that needs to be retracted and pulled out. When the pulling force received by the other end of the take-up wire 140 exceeds a preset pulling force (i.e., the pulling force F1 described below), the rotating cylinder 130 rotates in the first direction. 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 rotating cylinder 130, and at least one limiting block 163 is fixedly installed on one side inside the housing 119 close to the clamping block 161 (i.e., the upper surface of the bottom plate 112, that is, the surface of the bottom plate 112 facing the rotating cylinder 130). When the clamping block 161 is clamped with the limiting block 163, the rotation of the rotating cylinder 130 in a second direction opposite to the first direction is restricted. It should be noted that the first direction in the embodiments of the present application may refer to the rotation direction centered on the central shaft 120. For example, the first direction in the embodiments of the present application may be Figure 1 , Figure 2 and Figure 4 the counterclockwise direction in Figure 3 that is, the clockwise direction in

[0036] In some embodiments, as Figure 5As shown, the housing 111 may include a top plate 1111 and side plates 1112. A plurality of hollow holes 114 may be formed in the top plate 1111 and / or the side plates 1112. By forming the hollow holes 114 in the top plate 1111 and / or the side plates 1112, redundant use of manufacturing materials for the housing 111 can be avoided, thus reducing the relatively high production cost. In addition, by forming the hollow holes 114, the weight of the housing 111 can be reduced, thereby reducing the weight of the entire wire reel 100, which facilitates the transportation, installation, and use of the wire reel 100. In some embodiments, the top plate 1111 and the side plates 1112 may be an integrally formed structure. For example, the top plate 1111 and the side plates 1112 may be integrally formed by means of casting or the like. In some embodiments, the top plate 1111 and the side plates 1112 may also be a split structure, and then connected to form the housing 111 by means of welding, threaded connection, or the like.

[0037] In some embodiments, the number of the hollow holes 114 in the top plate 1111 and / or the side plates 1112 may be 2 to 8. This can fully reduce the materials used in manufacturing the housing 111, reduce the production cost, and effectively reduce the weight of the housing 111, facilitating the transportation, installation, and use of the wire reel 100. Preferably, as Figure 5 shown, the number of the hollow holes 114 in the top plate 1111 and / or the side plates 1112 may be 4. This can ensure that the top plate 1111 and / or the side plates 1112 have good structural strength while fully reducing the materials used in manufacturing the housing 111 and reducing the weight of the housing 111, making the housing 111 not easily damaged and having a relatively high service life.

[0038] In some embodiments, as Figure 5 shown, a plurality of the hollow holes 114 in the top plate 1111 may be symmetrically distributed about the axis of the central axis 120. This can ensure that the top plate 1111 has good structural strength. In some embodiments, the area ratio of the hollow holes 114 in the top plate 1111 may be 0.5 to 0.85. This can both reduce the weight and the materials used of the top plate 1111 while ensuring that the top plate 1111 has good structural strength.

[0039] In some embodiments, as Figure 5 shown, a plurality of the hollow holes 114 in the side plates 1112 may be equally spaced around the axis of the central axis 120 on the side plates 1112. This can ensure that the side plates 1112 have good structural strength. In some embodiments, the area ratio of the hollow holes 114 in the side plates 1112 may be 0.5 to 0.9. This can both reduce the weight and the materials used of the side plates 1112 while ensuring that the side plates 1112 have good structural strength.

[0040] In some embodiments, the other end of the take-up wire 140 can pass through the hollow hole 114 on the side plate 1112 and be located outside the housing 110. In some embodiments, in combination with Figure 1 and Figure 5 As shown, when the take-up wire 140 in the take-up device 100 is wound around the drum 130 in the first direction, the other end of the take-up wire 140 can pass through the hollow hole 114 on the left side of the side plate 1112, that is, the take-up device 100 exits from the left side. In some embodiments, both the left and right sides of the side plate 1112 may have hollow holes 114. When the take-up wire 140 in the take-up device 100 is wound around the drum 130 in the second direction, the other end of the take-up wire 140 can pass through the hollow hole 114 on the right side of the side plate 1112, that is, the take-up device 100 exits from the right side. By providing hollow holes 114 on both the left and right sides of the side plate 1112, the housing 111 can meet the requirements of two usage scenarios where the take-up device 100 exits from the left side and from the right side. The take-up devices 100 in the two usage scenarios can share one housing 111, thus reducing the mold opening cost and material cost of manufacturing the housing 111.

[0041] In some embodiments, as Figure 4 shown, a notch 121 can be provided on the side surface of the central shaft 120, and the inner end 1311 of the torsion spring 131 can be snapped into the notch 121 to achieve relative fixation with the central shaft 120. In some embodiments, the outer end 1312 of the torsion spring 131 can be fixed inside the drum 130 by screws 1313. For example, the outer end 1312 of the torsion spring 131 can be fixedly connected to the inner bottom surface of the drum 130 by screws 1313. In some embodiments, the outer end 1312 of the torsion spring 131 can also be fixedly connected to the inner side wall of the drum 130 by screws. Through the above settings, it is convenient for the staff to disassemble, install or adjust the torsion spring 131, etc.

[0042] In some embodiments, in combination with Figures 1 to 3 As shown, a plurality of radial reinforcing ribs 135 can be provided on the upper surface and / or the lower surface of the drum 130. The plurality of radial reinforcing ribs 135 are radially distributed in a spoke-like manner from the center of the upper surface and / or the lower surface of the drum 130 and extend to the edge of the upper surface and / or the lower surface of the drum 130. In some embodiments, in combination with Figures 1 to 3As shown, multiple circumferential reinforcing ribs 136 may be provided on the upper surface and / or the lower surface of the rotating cylinder 130. The multiple annular reinforcing ribs 136 have different diameters from small to large and are concentrically distributed around the center of the upper surface and / or the lower surface of the rotating cylinder 130. By providing multiple radial reinforcing ribs 135 and / or multiple circumferential reinforcing ribs 136 on the upper surface and / or the lower surface of the rotating cylinder 130, the strength and rigidity of the rotating cylinder 130 can be enhanced without increasing the wall thickness of the rotating cylinder 130. Thus, while ensuring a relatively high service life of the rotating cylinder 130, the material consumption for manufacturing the rotating cylinder 130 can be saved, the gravity of the rotating cylinder 130 can be reduced, the cost can be lowered, and moreover, the skew and deformation of the rotating cylinder 130 caused by uneven stress due to uneven wall thickness of the rotating cylinder 130 can be overcome.

[0043] The working mechanism of the take-up device 100 will be exemplarily described below in conjunction with the structure of the take-up device 100.

[0044] As an exemplary description, when the staff pulls out the target object, that is, when pulling the other end of the take-up wire 140 to move in a direction away from the inside of the housing 110 (i.e., the other end of the take-up wire 140 is pulled out), a part of the wire wound around the rotating cylinder 130 will be released from the rotating cylinder 130, driving the rotating cylinder 130 to rotate in a first direction. Since the outer end 1312 of the torsion spring 131 is fixedly connected to the inner side wall of the rotating cylinder 130, the rotation of the rotating cylinder 130 in the first direction will drive the outer end 1312 of the torsion spring 131 to rotate in the first direction, and the inner end 1311 of the torsion spring 131 will remain stationary, causing the torsion spring 131 to undergo bending elastic deformation and torsion in the plane, specifically manifested as radial expansion deformation or contraction deformation of the torsion spring 131. For example, as Figure 4 shown, the winding direction of the torsion spring 131 around the central axis 120 is a second direction opposite to the first direction ( Figure 4 the clockwise direction in the figure). When the outer end 1312 of the torsion spring 131 rotates in the first direction, the torsion spring 131 undergoes radial expansion deformation and generates an elastic force. This elastic force acts on the rotating cylinder 130 and provides a pulling force F1 to the take-up wire 140. The pulling force F1 can cause the rotating cylinder 130 to rotate in the second direction when the staff stops pulling the other end of the take-up wire 140, making the other end of the take-up wire 140 move in a direction towards the inside of the housing 110 (i.e., the other end of the take-up wire 140 is retracted), thereby retracting the target object. Among them, the frictional force generated by the relative movement between the components in the take-up device 100 (for example, between the take-up wire 140 and the rotating cylinder 130, between the rotating cylinder 130 and the central axis 120, etc.) is f.

[0045] In some embodiments, at least one bearing may be provided between the rotating cylinder 130 and the central shaft 120, which can reduce the noise when the rotating cylinder 130 rotates around the central shaft 120 and effectively reduce the frictional force between the rotating cylinder 130 and the central shaft 120, so that the frictional force can be reduced to 20% of the original value, enabling the staff to easily pull the target object, ensuring the smoothness of the target object during the pulling out and retracting processes, and giving the staff a good operation experience and feel. In addition, the bearing can also prevent the central shaft 120 from tilting due to wear between the rotating cylinder 130 and the central shaft 120 after long-term use of the wire rewinder 100, resulting in the tilting of the rotating cylinder 130 during rotation and contact with the outer shell 110 to generate friction, causing difficulty in pulling the other end (i.e., the target object) of the wire 140 or even jamming of the rotating cylinder 130 and the outer shell 110 and inability to pull the other end of the wire 140.

[0046] Next, a detailed description will be further given on how the wire rewinder 100 enables the staff to have a good feel when pulling the target object.

[0047] When the staff pulls the other end of the wire 140, the pulling force F2 (F2 is in the opposite direction to F1) applied by the staff to the other end of the wire 140 (or the target object) needs to satisfy F2 > F1 + f, and the reaction force of the other end of the wire 140 on the staff is the magnitude of F2; when the target object (i.e., the other end of the wire 140) remains stationary, at this time, the other end of the wire 140 has a tendency to retract, and the pulling force F3 applied by the staff to the wire 140 is F3 = F1 - f (F3 is in the opposite direction to F1), and the reaction force of the other end of the wire 140 on the staff is the magnitude of F3. It can be obtained therefrom that F2 - F3 > 2f.

[0048] Furthermore, during the actual use of the wire rewinder 100, when the staff pulls the target object to drive the other end of the wire 130 to be pulled out, since the pulling force applied by the staff to the target object is not uniform and continuous, the other end of the wire 140 will have a tendency to be pulled out for a while and a tendency to be retracted for a while, and the other end of the wire 140 will frequently switch between these two states, resulting in a sudden change in the reaction force of the other end of the wire 140 on the staff between F2 and F3. According to F2 - F3 > 2f, it can be seen that if the frictional force f generated by the relative movement between the components in the wire rewinder 100 is greater, it will cause the reaction force of the other end of the wire 140 on the staff to jump within a large range when the staff pulls the other end of the wire 140, resulting in a poor feel for the staff. In the wire rewinder 100 provided in the embodiments of the present application, by providing at least one bearing between the rotating cylinder 130 and the central shaft 120 (for example, Figure 2The first bearing 151 and the second bearing 152 shown in [Figure] can reduce the frictional force between the rotating cylinder 130 and the central shaft 120, thereby reducing the frictional force f generated by the relative movement between the components in the wire winder 100 during the pulling out and retracting of the target object. When the staff pulls the other end of the wire 140, the reaction force of the other end of the wire 140 on the staff can jump within a small range, ensuring that the staff has a good feel.

[0049] Further, the bearing provided between the rotating cylinder 130 and the central shaft 120 may include an outer ring (for example, Figure 2 the first outer ring 1511 and the second outer ring 1521 shown in [Figure]), an inner ring (for example, Figure 2 the first inner ring 1512 and the second inner ring 1522 shown in [Figure]) and rolling elements provided between the outer ring and the inner ring (for example, Figure 2 the first rolling element 1513 shown in [Figure]). Wherein, the inner ring is sleeved on the central shaft 120 and fixed to the central shaft 120, the outer ring is fixed to the rotating cylinder 130. When the rotating cylinder 130 rotates around the central shaft 120, the outer ring will rotate relative to the inner ring, and the rolling elements will roll between the inner ring and the outer ring, making the friction between the outer ring and the inner ring a rolling friction. The frictional force of rolling friction is small, which can reduce the frictional force between the rotating cylinder 130 and the central shaft 120, thereby reducing the frictional force f generated by the relative movement between the components in the wire winder 100 during the pulling out and retracting of the target object. When the staff pulls the other end of the wire 140, the reaction force of the other end of the wire 140 on the staff can jump within a small range, ensuring that the staff has a good feel. In some embodiments, the rolling elements can be balls, cylindrical rollers, tapered rollers, needle rollers, etc.

[0050] In some embodiments, such as Figure 2As shown, at least one bearing disposed between the rotating cylinder 130 and the central shaft 120 may include a first bearing 151 and a second bearing 152. The first bearing 151 and the second bearing 152 may be sequentially disposed between the rotating cylinder 130 and the central shaft 120 along the axial direction of the rotating cylinder 130. Among them, the first bearing 151 includes a first outer ring 1511, a first inner ring 1512, and a first rolling element 1513 disposed between the first outer ring 1511 and the first inner ring 1512; the second bearing 152 includes a second outer ring 1521, a second inner ring 1522, and a second rolling element 1523 disposed between the second outer ring 1521 and the second inner ring 1522. As an exemplary illustration, a first bearing mount 132 and a second bearing mount 133 are respectively disposed on the upper surface and the lower surface of the rotating cylinder 130, and the first bearing 151 and the second bearing 152 are respectively installed in the first bearing mount 132 and the second bearing mount 133. Among them, the first inner ring 1512 and the second inner ring 1522 are fixed to the central shaft 120, and the first outer ring 1511 and the second outer ring 1521 are respectively fixed to the first bearing mount 132 and the second bearing mount 133.

[0051] In the take-up device 100 provided in the embodiment of the present application, the blocking structure 160 can be used to restrict the rotating cylinder 130 from continuing to rotate in the second direction when the staff pulls the target object to the expected position, so that the target object can hover at the expected position, facilitating the staff to use the target object or operate on it, so that the staff does not need to use additional actions to stabilize the target object at the expected position, thereby reducing the working intensity of the staff. Specifically, the blocking 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 disposed on the lower surface of the rotating cylinder 130, and at least one limiting block 163 is fixedly installed on one side of the housing 119 close to the clamping block 161 (i.e., the upper surface of the bottom plate 112, that is, the surface of the bottom plate 112 facing the rotating cylinder 130). When the clamping block 161 is clamped with the limiting block 163 (that is, the free end 1612 of the clamping block 161 described below and the blocking portion 1631 of the limiting block 163), the rotation of the rotating cylinder 130 in the second direction can be restricted, and when the clamping block 161 is no longer clamped with the limiting block 163, the restriction on the rotation of the rotating cylinder 130 in the second direction will be released.

[0052] Further, the limiting block 163 has a blocking portion 1631; wherein, the clamping block 161 includes a connecting end 1611 and a free end 1612, and a connecting shaft 134 rotatably connected to the connecting end 1611 is provided on the lower surface of the rotating cylinder 130, and the connecting end 1611 is clamped within 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 jointly provided on the upper surface of the rotating cylinder 130. Correspondingly, at least one limiting block 163 is fixedly installed on one side surface of the housing 111 close to the rotating cylinder 130.

[0053] As an exemplary illustration, when a staff member pulls the other end of the retracting wire 140, the part of the retracting wire 140 wound around the rotating cylinder 130 is released from the rotating cylinder 130, causing the rotating cylinder to rotate in the first direction. The coil spring 131 undergoes a contraction deformation to generate an elastic force. When the other end of the retracting wire 140 (i.e., the target object) reaches the expected position, the staff member can stop pulling the other end of the retracting wire 140. The coil spring 131 resumes deformation, and the rotating cylinder 130 rotates in the second direction under the elastic force of the coil spring 131. At the same time, the clamping block 161 is driven to rotate in the second direction, such that when the clamping block 161 passes by the limiting block 163, an interference occurs between the free end 1612 of the clamping block 161 and the blocking portion 1631 of the limiting block 163, and an abutment occurs with the blocking portion 1631, thereby restricting the rotating cylinder 130 from continuing to rotate in the second direction, so that the target object hovers at the expected position.

[0054] When it is necessary to retract the other end of the retracting wire 140 (i.e., the target object), the staff member can pull the other end of the retracting wire 140 by pulling the target object in the hovering state again. At this time, the clamping block 161 rotates around the connecting shaft 134 under the elastic force of the U-shaped spring 162, such that the free end of the clamping block 161 no longer interferes with the blocking portion 1631. Thus, after the staff member stops pulling the other end of the retracting wire 140, the blocking portion 1631 no longer hinders the rotation of the clamping block 161, enabling the rotating cylinder 130 to continue rotating in the second direction, thereby achieving the purpose of retracting the other end of the retracting wire 140 (i.e., the target object).

[0055] The clamping structure 160 in the embodiments of the present application does not have too high requirements for the stiffness of the outer shell 110 and the rotating cylinder 130. Even if the stiffness of the outer shell 110 and the rotating cylinder 130 is not large, it can still meet the functional requirements for the clamping structure 160 to restrict the continuous rotation of the rotating cylinder 130. Therefore, in some embodiments, the outer shell 110 and the rotating cylinder 130 can be formed by casting. The stiffness of the outer shell 110 and the rotating cylinder 130 formed by casting can not only meet the functional requirements for the clamping structure 160 to restrict the continuous rotation of the rotating cylinder 130, but also the casting cost is relatively low, which can reduce the production cost of the wire retractor 100.

[0056] In the take-up reel 100 provided in the embodiment of the present application, by installing the second end of the central shaft 120 into the mounting hole 171 of the adjustment plate 170, and then fixing the adjustment plate 170 to the upper surface of the housing 110 with screws, it is possible to prevent the rotating cylinder 130 from driving the central shaft 120 to rotate during the process of pulling out or retracting the other end of the take-up wire 140. The rotation of the central shaft 120 will cause the position of the inner end 1311 of the coil spring 131 to change, resulting in a change in the tension provided by the coil spring 131 to the take-up wire 140, which will affect the smoothness and feel of the staff when pulling out or retracting the other end of the take-up wire 140.

[0057] In some embodiments, in order to ensure that the take-up reel 100 can adapt to target objects of different weights, that is, when the other end of the take-up wire 140 of the take-up reel 100 is connected to target objects of different weights, the target objects of different weights can be hovered at the initial position by the take-up reel 100 without falling when not being pulled. The staff can adjust the tension provided by the coil spring 131 to the take-up wire 140 according to the weight of the target object connected to the other end of the take-up wire 140, so that the tension provided by the coil spring 131 to the take-up wire 140 can balance the gravity of the target object, thereby being able to hover the target object at its initial position when the target object is not being pulled. Specifically, before pulling the target object, the target staff can rotate the adjustment plate 170 to rotate the central shaft 120 together, 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 provided by the coil spring 131 to the take-up wire 140, so as to ensure that the take-up reel 100 can adapt to target objects of different weights, and avoid the situation that when the other end of the take-up wire 140 is connected to a target object with a greater weight, the initial tension provided by the coil spring to the take-up wire is not sufficient to balance the gravity of the target object, resulting in the target object not being able to hover at its initial position and falling to contact the ground and being soiled.

[0058] As an exemplary illustration, when the target object connected to the other end of the take-up wire 140 of the take-up reel 100 is replaced with a target object of different weight, the staff can first remove the screws connecting the upper surface of the housing 110 and the adjustment plate 170, so that the adjustment plate 170 is no longer fixed to the upper surface of the housing 110, and then rotate the adjustment plate 170 to rotate the central shaft 120, so as 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 with screws, so that the tension provided by the coil spring 131 to the take-up wire 140 can balance the gravity of the replaced target object, thereby enabling the take-up reel 100 to adapt to the replaced target object.

[0059] In some embodiments, in order to rotatably mount the first end of the central shaft 120 to the bottom plate 112, an installation hole adapted to the shape of the first end of the central shaft 120 may be formed in the bottom plate 112. By positioning the first end of the central shaft 120 within the installation hole, the first end of the central shaft 120 can be rotatably mounted to the bottom plate 112. Among them, the shape of the second end of the central shaft 120 may be a cylinder or other rotational body.

[0060] In some embodiments, in order to reduce the friction between the first end of the central shaft 120 and the installation hole in the bottom plate 112, enable the central shaft 120 to rotate smoothly when the staff rotates the adjustment plate 170, and reduce the operation burden of the staff, a bearing (not shown in the figure) may be provided between the first end of the central shaft 120 and the installation hole. Among them, the outer ring of the bearing is fixed to the inner wall of the installation hole, and the 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 installation hole in the bottom plate 112, not only can the friction between the first end of the central shaft 120 and the installation hole in 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 improved.

[0061] In some embodiments, in order to enable the adjustment plate 170 to be fixedly connected to the upper surface of the housing 110 by 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 a circular array around the axis of the assembly hole 171. Correspondingly, threaded connection holes corresponding to the plurality of through holes 172 may be provided on the upper surface of the housing 110. The screws may pass through the through holes 172 and be threadedly connected to the corresponding threaded connection holes on the upper surface of the housing 110, thereby achieving 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 and be threadedly connected to the threaded connection holes, the angle of each rotation of the adjustment plate 170 should be n times the angle between the connecting lines from the centers of adjacent two through holes 172 to the center of the assembly hole 171 (n = 0, 1, 2, 3...). It should be noted that Figure 1 the number of through holes 172 shown in Figure 1 is only an example. The number of through holes 172 may be

[0062] In some embodiments, in order to facilitate the staff to rotate the adjustment plate 170, such asFigure 1 As shown, there are also provided at least two tooling connection holes 172 on the adjustment plate 170, and the at least two working connection holes 172 can be symmetrically distributed about the axis of the assembly hole 171. By providing at least two tooling connection holes 172, corresponding rotating tooling can be connected, and the staff can rotate the adjustment plate 170 by operating the rotating tooling, with a relatively small operation burden, and can easily rotate the adjustment plate 170 by a certain angle. In some embodiments, the number of tooling connection holes 172 can be four as shown in Figure 1 the figure, or three, five, six, etc.

[0063] In some embodiments, for the convenience of the staff to rotate the adjustment plate 170, as Figure 1 shown, there are also provided at least two tooling connection holes 172 on the adjustment plate 170, and the at least two working connection holes 172 can be symmetrically distributed about the axis of the assembly hole 171. By providing at least two tooling connection holes 172, corresponding rotating tooling can be connected, and the staff can rotate the adjustment plate 170 by operating the rotating tooling, with a relatively small operation burden, and can easily rotate the adjustment plate 170 by a certain angle. In some embodiments, the number of tooling connection holes 172 can be four as shown in Figure 1 the figure, or three, five, six, etc.

[0064] Figure 6 is a schematic structural diagram of a rotating tooling according to some embodiments of the present application. Figure 7 is a schematic connection diagram of the rotating tooling and the wire take-up device according to some embodiments of the present application.

[0065] As Figure 6 and Figure 7As shown in the figure, the embodiment of the present application further provides a rotation tooling 200 for rotating the adjustment plate 170. The rotation tooling 200 may include a handle 210 and a connector 220 provided at one end of the handle 210. Among them, at least two connecting columns 221 corresponding to at least two tooling connection holes 173 on the adjustment plate 170 are provided on the connector 220, and the at least two connecting columns 221 can be used to insert into the at least two tooling connection holes 173. As an exemplary description, when a worker uses the rotation tooling 200 to rotate the adjustment plate 170, the connecting columns can be correspondingly inserted into the working connection holes, and then rotating the handle 210 can cause the adjustment plate 170 to rotate. Among them, by setting the at least two tooling connection holes 173 to be symmetrically distributed about the axis of the assembly hole 171, and then inserting the at least two connecting columns 221 into the at least two tooling connection holes 173, it can be fully ensured that the worker can drive the adjustment plate 170 to rotate together when rotating the handle 210. The beneficial effects that the embodiment of the present application may bring include but are not limited to: (1) By providing a bearing between the rotating cylinder and the central shaft, the noise and friction during the rotation of the rotating cylinder can be reduced, enabling the worker to easily pull out the target object with a good feel, and at the same time ensuring that the target object moves smoothly during the pulling out and retracting processes; (2) A hollow structure is provided on the housing of the wire reel, which can reduce the weight of the housing, thereby reducing the overall weight of the wire reel, facilitating the transportation, installation, and use of the wire reel, and at the same time reducing the material usage cost during the manufacture of the housing; (3) Both the left and right sides of the housing side plate have hollow holes, which can simultaneously meet the usage scenarios where the other end of the wire for pulling and retracting passes through the outer shell from the left and from the right. The same housing can be used in these two usage scenarios, thus reducing the mold opening cost and material cost during the manufacture of the housing; (4) Radial reinforcing ribs and / or annular reinforcing ribs are provided on the upper surface and / or lower surface of the rotating cylinder. Without increasing the wall thickness of the rotating cylinder, the strength and rigidity of the rotating cylinder can be enhanced, thereby ensuring a high service life of the rotating cylinder while saving the material usage for manufacturing the rotating cylinder, reducing the gravity of the rotating cylinder, reducing costs, and also overcoming the warping and deformation of the rotating cylinder caused by uneven stress due to uneven wall thickness; (5) By rotating the adjustment plate, the initial tension provided by the coil spring to the wire for retracting can be adjusted, enabling the wire reel to adapt to target objects of different weights, avoiding the situation where when the other end of the wire for retracting is connected to a target object with a greater weight, the initial tension provided by the coil spring to the wire for retracting is insufficient to balance the gravity of the target object, resulting in the target object falling and contacting the ground and getting soiled without being pulled; (6) By using the rotation tooling to rotate the adjustment plate, the operation burden of the worker can be reduced, enabling the worker to easily rotate the adjustment plate by a certain angle; (7) The stiffness requirement for the outer shell of the clamping structure is not high, and the outer shell can be formed by casting, thereby reducing the manufacturing cost.
