Abstract

The present invention discloses a redundant line winding system and method for an electric meter box, belonging to the technical field of winding devices, comprising a storage drum, a rotating rod rotatably provided inside the storage drum, at least one winding wheel provided on the outside of the rotating rod, and the winding wheel and the storage drum being rotatably connected via a bearing, a clamp provided on the outside of the rotating rod, and the clamp movably connected to the rotating rod via an elastic member. After the wire is completely wound up by the winding wheel, the wire will generate a pulling force on the winding wheel. At this time, the clamp moves through the elastic member and no longer drives the winding wheel to rotate through the bevel gear ring, while the rotating rod continues to drive another winding wheel to rotate and wind other wires. When the other wires are completely wound up, the rotating rod stops rotating. When winding up multiple redundant wires, the winding device can automatically select whether to wind up according to the length of the wound wire, not only preventing the wire that is too short from being pulled and broken, but also allowing all the wires to be wound up together, making it easy to use and having a wide range of applications.

Description

Technical Field

[0001] The present invention relates to the technical field of electric meter box wire winding, and in particular to an electric meter box redundant line winding system and a winding method. Background Art

[0002] Modern production, life and manufacturing are inseparable from the demand for electricity. At the same time, in order to use electricity more safely and conveniently, it is necessary to limit and summarize the numerous lines in the meter box. Most of them use winding devices to organize the wire lines.

[0003] For example, application number 202011470194.3 discloses a redundant line winding system for an electric meter box, comprising a base plate, the lower end of the base plate is fixedly connected to a support seat, the upper end of the base plate is fixedly connected to a box body, the interior of the box body is rotatably connected to a winding disk, the right end of the winding disk is fixedly connected to two symmetrical protrusions, the protrusions are engaged with the inner wall of the box body, a rotating groove is provided inside the box body, the interior of the rotating groove is rotatably connected to a connecting block, the connecting block is fixedly connected to the winding disk, the left end of the connecting block is fixedly connected to a turntable, and the turntable is in contact with the box body. The present invention can enclose the wires inside the box body by designing the function of the box body, and can achieve a sealing effect on the wires through the function of the sealing block, and can provide a protective effect on the wires, effectively preventing dust from adhering to the surface of the wires, and by designing multiple grooves, the device can be used to reel multiple wires.

[0004] The above technology has the following shortcomings: Since there are usually multiple redundant wires inside the meter box, and the redundant lengths of the multiple wires are also different, the above winding device is prone to the following problems when winding multiple redundant wires of different lengths:

[0005] 1. When the winding device completely winds up the redundant wires, the wire with the shortest redundant length is subjected to the greatest tension, and this wire is prone to breakage under long-term tension.

[0006] 2. In order to avoid the shortest redundant wire from being pulled (just to reel in the shortest redundant wire), the wires longer than this wire cannot be completely reeled in, which limits its use. Summary of the Invention

[0007] The object of the present invention is to provide a redundant circuit winding system and a winding method for an electric meter box, so as to solve the deficiencies in the background technology.

[0008] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a redundant line winding system for an electric meter box, comprising a storage cylinder, a rotating rod is rotatably provided inside the storage cylinder, at least one winding wheel is provided on the outside of the rotating rod, and the winding wheel is rotatably connected to the storage cylinder through a bearing, a clamp is provided on the outside of the rotating rod, and the clamp is movably connected to the rotating rod through an elastic member, a helical gear ring corresponding to the position of the clamp is fixedly provided on the inside of the winding wheel, and the end of the clamp is embedded in the tooth groove of the helical gear ring, the rotating rod pushes the helical gear ring to rotate through the clamp, and the helical gear ring drives the winding wheel to rotate, and when the pulling force applied to any winding wheel is greater than the elastic force of the elastic member, the clamp does not drive the helical gear ring to rotate through the movement of the elastic member.

[0009] In a preferred embodiment, the winding wheels are provided with at least three, and the winding wheels respectively wind up wire one, wire two and wire three, and the rotating rod is rotated. The rotating rod drives the three winding wheels to rotate and wind up wire one, wire two and wire three at the same time through the cooperation of the clamping member and the bevel gear ring. The length of wire three is set. When the winding wheel completely winds up wire one, wire one will generate a pulling force on the winding wheel. At this time, the clamping member moves through the elastic member and no longer drives the winding wheel to rotate through the bevel gear ring, and the rotating rod will continue to drive the other two winding wheels to rotate and wind up wire two and wire three. When wire two and wire three are completely wound up, the rotating rod stops rotating.

[0010] In a preferred embodiment, a bracket is provided on one side of the clamp, and a spring shaft is fixedly provided on the inner side of one end of the clamp close to the bracket, and both ends of the spring shaft are fixedly connected to the bracket. The spring shaft is used to keep the clamp in the same position when there is no force on the clamp. When the force on the clamp is greater than the elastic force of the spring shaft, the clamp can be rotated a certain distance. After the force on the clamp disappears, the clamp is rotated to the initial position again.

[0011] In a preferred embodiment, the interior of the rotating rod is hollow, a limit block is fixedly provided on one side of the bracket, and the bracket is slidingly connected to the rotating rod, an elastic rib is provided on the side of the limit block close to the inner wall of the rotating rod, and the limit block is connected to the inner wall of the rotating rod through the elastic rib, a screw is provided in the middle of the rotating rod, and the screw is threadedly connected to the end of the rotating rod, a pull rope corresponding to the position of the limit block is fixedly provided on the outside of the screw, and one end of the pull rope is fixedly connected to the limit block.

[0012] In a preferred embodiment, the screw is rotated counterclockwise, and the screw pulls the limit block to move inwardly of the rotating rod through the pull rope. The limit block pulls the clamp away from the bevel gear ring through the bracket, so that the end of the clamp is disengaged from the tooth groove of the bevel gear ring.

[0013] In a preferred embodiment, a ceramic tube corresponding to the position of the winding wheel is provided on the top of the storage cylinder, and the ceramic tube is fixedly embedded in the side wall of the storage cylinder, and a clamping ring corresponding to the position of the ceramic tube is fixedly provided on the outside of the winding wheel.

[0014] In a preferred embodiment, a rotating assembly is further provided at one end of the rotating rod, which facilitates manual rotation of the rotating rod. The rotating assembly includes a collar, a connecting rod and a handle, and the collar is fixedly sleeved on the end of the rotating rod, the connecting rod is fixedly set at the bottom of the collar, and the handle and the connecting rod are rotatably connected through a rotating shaft. When rotating, the handle is held manually and the collar is rotated by the handle, and the collar drives the rotating rod to rotate.

[0015] In a preferred embodiment, both ends of the storage tube are provided with end covers, and the end covers are detachably connected to the storage tube by screws.

[0016] In a preferred embodiment, the storage tube is made of transparent acrylic material.

[0017] The present invention also provides a method for winding up a redundant circuit of an electric meter box. The method is implemented by a system for winding up a redundant circuit of an electric meter box. The method comprises the following steps:

[0018] S: The storage tube is fixed to the bottom of the inner cavity of the meter box through a clamping seat, and the bottom end of the redundant wire is inserted into the clamping ring through the ceramic tube;

[0019] S: The rotating rod is rotated by the rotating assembly, and the rotating rod drives the bevel gear ring to rotate through the clamp, and the bevel gear ring drives the winding wheel to rotate and rewind the wire;

[0020] S: After the wire is completely wound up by the reel, the wire will generate a pulling force on the reel. At this time, the clamp moves through the spring shaft and no longer drives the reel to rotate through the bevel gear ring. Instead, the rotating rod will continue to drive the other reel to rotate and wind up other wires. When the other wires are completely wound up, the rotating rod will stop rotating.

[0021] S: When you need to pull the wire out of the storage tube, turn the screw counterclockwise. The screw rotates, and the limit block is pulled toward the inside of the rotating rod through the pull rope. The limit block pulls the clamp away from the bevel gear ring through the bracket, so that the end of the clamp is separated from the tooth groove of the bevel gear ring;

[0022] S: When the wire needs to be rewound, turn the screw clockwise. The pull rope is not under stress, and the elastic tendon drives the limit block to move toward the inner wall of the rotating rod through its own elasticity. The limit block drives the clamp to reset through the bracket, and the end of the clamp is re-embedded in the bevel gear ring to rewind the wire.

[0023] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0024] 1. After the wire is completely wound up by the winding wheel of the present invention, the wire will generate tension on the winding wheel. At this time, the clamping member is activated by the elastic member, and the winding wheel is no longer driven to rotate by the bevel gear ring. Instead, the rotating rod will continue to drive the other winding wheel to rotate and wind up other wires. When the other wires are completely wound up, the rotating rod stops rotating. When winding up multiple redundant wires, the winding device can automatically select whether to wind up according to the length of the wound wire. This not only prevents the short wire from being pulled and broken, but also allows all the wires to be wound up together, which is convenient to use and has a wide range of applications.

[0025] 2. The present invention provides a ceramic tube corresponding to the position of the winding wheel on the top of the storage tube, and the ceramic tube is fixedly embedded in the side wall of the storage tube. A clamping ring corresponding to the position of the ceramic tube is fixedly provided on the outside of the winding wheel. Before winding the wire, the staff inserts the end of the wire into the ceramic tube and the end of the wire into the clamping ring. At this time, the winding wheel is rotated by the rotating rod, and the rotating winding wheel winds the wire through the clamping ring. The ceramic tube can prevent the wire from being scratched when winding.

[0026] 3. The present invention rotates the screw counterclockwise. When the screw rotates, the limit block is pulled toward the inside of the rotating rod by the pull rope. The limit block pulls the clamp away from the bevel gear ring through the bracket, so that the end of the clamp is separated from the tooth groove of the bevel gear ring. In this way, when the wire is pulled, the clamp does not affect the rotation of the bevel gear ring, which facilitates the rapid pulling out of the wire and prevents the wire from being broken.

[0027] 4. The present invention manually holds the handle and rotates the collar through the handle, so that the collar can drive the rotating rod to rotate. The rotating assembly composed of the above components can save labor when manually rotating the rotating rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] It should be noted that when an element is referred to as being “fixed to” another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or there may be an intermediate element.

Different from the prior art, a clamping member 21 is provided on the outside of the rotating rod 2, and the clamping member 21 is movably connected to the rotating rod 2 through an elastic member, and a bevel gear ring 31 corresponding to the position of the clamping member 21 is fixedly provided on the inside of the winding wheel 3, and the end of the clamping member 21 is embedded in the tooth groove of the bevel gear ring 31, the rotating rod 2 pushes the bevel gear ring 31 to rotate through the clamping member 21, and the bevel gear ring 31 drives the winding wheel 3 to rotate. When the pulling force applied to any winding wheel 3 during rotation is greater than the elastic force of the elastic member, the clamping member 21 does not drive the bevel gear ring 31 to rotate through the movement of the elastic member.

[0042] See also Figure 3 As shown, in order to better illustrate the working principle of the present application, in this embodiment, three winding wheels 3 are set, that is, the storage drum 1 needs to store three redundant wires in the meter box, and the three redundant wires are wound with the three winding wheels 3 respectively. We name the three redundant wires as wire one, wire two and wire three respectively. The rotating rod 2 is manually rotated, and the rotating rod 2 drives the three winding wheels 3 to rotate and rewind the lengths of wire one, wire two and wire three at the same time through the cooperation of the clamp 21 and the bevel gear ring 31. When the winding wheel 3 completely rewinds wire one, the wire When the wire 2 and the wire 3 are completely wound up, the rotating rod 2 stops rotating. When the winding device is used to wind up multiple redundant wires, it can automatically choose whether to wind up according to the length of the wound wire. This not only avoids the breakage of the wire that is too short due to tension, but also can wind up all the wires together, which is convenient to use and has a wide range of applications.

[0043] Both ends of the storage tube 1 are provided with end covers 12, and the end covers 12 are detachably connected to the storage tube 1 by screws. After opening the end covers 12, the rotating rod 2 and the winding wheel 3 inside the storage tube 1 can be maintained, and the storage tube 1 is made of transparent acrylic material, which makes it convenient for manual observation of the winding state of the wire.

[0044] A ceramic tube 11 corresponding to the position of the winding wheel 3 is provided on the top of the storage tube 1, and the ceramic tube 11 is fixedly embedded in the side wall of the storage tube 1. A clamping ring 32 corresponding to the position of the ceramic tube 11 is fixedly provided on the outside of the winding wheel 3. Before winding the wire, the staff inserts the end of the wire into the ceramic tube 11 and the end of the wire into the clamping ring 32. At this time, the winding wheel 3 is rotated by the rotating rod 2, and the rotating winding wheel 3 winds the wire through the clamping ring 32. The ceramic tube 11 provided can prevent the wire from being scratched when winding.

[0045] A rotating assembly 22 is also provided at one end of the rotating rod 2. The rotating assembly 22 facilitates manual rotation of the rotating rod 2. The rotating assembly 22 includes a collar 221, a connecting rod 222 and a handle 223. The collar 221 is fixedly sleeved on the end of the rotating rod 2, the connecting rod 222 is fixedly provided at the bottom of the collar 221, and the handle 223 is rotatably connected to the connecting rod 222 through a rotating shaft. When rotating, the handle 223 is manually held and the collar 221 is rotated by the handle 223, and the collar 221 can drive the rotating rod 2 to rotate. The rotating assembly 22 composed of the above components can save effort when manually rotating the rotating rod 2.

[0046] See also Figure 3 and Figure 4As shown, a bracket 23 is provided on one side of the clamp 21, and a spring shaft 24 is fixedly provided on the inner side of one end of the clamp 21 close to the bracket 23, and both ends of the spring shaft 24 are fixedly connected to the bracket 23. The spring shaft 24 is used to keep the clamp 21 in the same position when there is no force on the clamp 21, and when the force on the clamp 21 is greater than the elastic force of the spring shaft 24, the clamp 21 can be rotated a certain distance, and after the force on the clamp 21 disappears, the clamp 21 is rotated to the initial position again, so that the clamp 21 can drive the winding wheel 3 to rotate, and when the winding wheel 3 is pulled, the clamp 21 no longer drives the bevel gear ring 31 to rotate.

[0047] Example 2

[0048] See also Figure 1 and Figure 2 As shown, the redundant line winding system of an electric meter box described in this embodiment includes a storage cylinder 1, a rotating rod 2 is rotatably provided inside the storage cylinder 1, and at least one winding wheel 3 is rotatably provided on the outside of the rotating rod 2, and the winding wheel 3 is rotatably connected to the storage cylinder 1 through a bearing. Different from the prior art, a clamping member 21 is provided on the outside of the rotating rod 2, and the clamping member 21 is movably connected to the rotating rod 2 through an elastic member, and a bevel gear ring 31 corresponding to the position of the clamping member 21 is fixedly provided on the inside of the winding wheel 3, and the end of the clamping member 21 is embedded in the tooth groove of the bevel gear ring 31, the rotating rod 2 pushes the bevel gear ring 31 to rotate through the clamping member 21, and the bevel gear ring 31 drives the winding wheel 3 to rotate. When the pulling force applied to any winding wheel 3 during rotation is greater than the elastic force of the elastic member, the clamping member 21 does not drive the bevel gear ring 31 to rotate through the movement of the elastic member.

[0049] See also Figure 3 As shown, in order to better illustrate the working principle of the present application, in this embodiment, three winding wheels 3 are set, that is, the storage drum 1 needs to store three redundant wires in the meter box, and the three redundant wires are wound with the three winding wheels 3 respectively. We name the three redundant wires as wire one, wire two and wire three respectively. The rotating rod 2 is manually rotated, and the rotating rod 2 drives the three winding wheels 3 to rotate and rewind the lengths of wire one, wire two and wire three at the same time through the cooperation of the clamp 21 and the bevel gear ring 31. When the winding wheel 3 completely rewinds wire one, the wire When the wire 2 and the wire 3 are completely wound up, the rotating rod 2 stops rotating. When the winding device is used to wind up multiple redundant wires, it can automatically choose whether to wind up according to the length of the wound wire. This not only avoids the breakage of the wire that is too short due to tension, but also can wind up all the wires together, which is convenient to use and has a wide range of applications.

[0050] Both ends of the storage tube 1 are provided with end covers 12, and the end covers 12 are detachably connected to the storage tube 1 by screws. After opening the end covers 12, the rotating rod 2 and the winding wheel 3 inside the storage tube 1 can be maintained, and the storage tube 1 is made of transparent acrylic material, which makes it convenient for manual observation of the winding state of the wire.

[0051] A ceramic tube 11 corresponding to the position of the winding wheel 3 is provided on the top of the storage tube 1, and the ceramic tube 11 is fixedly embedded in the side wall of the storage tube 1. A clamping ring 32 corresponding to the position of the ceramic tube 11 is fixedly provided on the outside of the winding wheel 3. Before winding the wire, the staff inserts the end of the wire into the ceramic tube 11 and the end of the wire into the clamping ring 32. At this time, the winding wheel 3 is rotated by the rotating rod 2, and the rotating winding wheel 3 winds the wire through the clamping ring 32. The ceramic tube 11 provided can prevent the wire from being scratched when winding.

[0052] A rotating assembly 22 is also provided at one end of the rotating rod 2. The rotating assembly 22 facilitates manual rotation of the rotating rod 2. The rotating assembly 22 includes a collar 221, a connecting rod 222 and a handle 223. The collar 221 is fixedly sleeved on the end of the rotating rod 2, the connecting rod 222 is fixedly provided at the bottom of the collar 221, and the handle 223 is rotatably connected to the connecting rod 222 through a rotating shaft. When rotating, the handle 223 is manually held and the collar 221 is rotated by the handle 223, and the collar 221 can drive the rotating rod 2 to rotate. The rotating assembly 22 composed of the above components can save effort when manually rotating the rotating rod 2.

[0053] See also Figure 3 and Figure 4 As shown, a bracket 23 is provided on one side of the clamp 21, and a spring shaft 24 is fixedly provided on the inner side of one end of the clamp 21 close to the bracket 23, and both ends of the spring shaft 24 are fixedly connected to the bracket 23. The spring shaft 24 is used to keep the clamp 21 in the same position when there is no force on the clamp 21, and when the force on the clamp 21 is greater than the elastic force of the spring shaft 24, the clamp 21 can be rotated a certain distance, and after the force on the clamp 21 disappears, the clamp 21 is rotated to the initial position again, so that the clamp 21 can drive the winding wheel 3 to rotate, and when the winding wheel 3 is pulled, the clamp 21 no longer drives the bevel gear ring 31 to rotate.

[0054] Since in the above embodiment 1, after the wire is wound up, when the redundant wire is needed later, the wire needs to be taken out from the storage tube 1. When the wire is pulled out, the winding wheel 3 drives the bevel gear ring 31 to reverse. At this time, due to the provision of the clamping member 21, there is friction between the clamping member 21 and the bevel gear ring 31, which will affect the pulling speed of the wire. If the wire is pulled out too quickly, it may also cause the wire to be broken. Therefore, we make the following solution:

[0055] See also Figure 5 and Figure 7As shown, the interior of the rotating rod 2 is hollow, and a limit block 25 is fixedly provided on one side of the bracket 23, and the bracket 23 is slidably connected to the rotating rod 2. The limit block 25 prevents the bracket 23 from sliding out of the rotating rod 2. An elastic rib 26 is provided on the side of the limit block 25 close to the inner wall of the rotating rod 2, and the limit block 25 is connected to the inner wall of the rotating rod 2 through the elastic rib 26. A screw 27 is provided in the middle of the rotating rod 2, and the screw 27 is threadedly connected to the end of the rotating rod 2. A pull rope 28 corresponding to the position of the limit block 25 is fixedly provided on the outer side of the screw 27, and one end of the pull rope 28 is fixedly connected to the limit block 25.

[0056] See also Figure 6 As shown, when the wire needs to be pulled out from the inside of the storage tube 1, the user rotates the screw 27 counterclockwise. When the screw 27 rotates, the limit block 25 is pulled toward the inside of the rotating rod 2 by the pull rope 28. The limit block 25 pulls the clamping member 21 away from the bevel gear ring 31 through the bracket 23, so that the end of the clamping member 21 is separated from the tooth groove of the bevel gear ring 31. In this way, when the wire is pulled, the clamping member 21 does not affect the rotation of the bevel gear ring 31, which facilitates the rapid pulling out of the wire while preventing the wire from being broken.

[0057] Example 3

[0058] See also Figure 1 As shown, the embodiment of the present invention provides a method for winding up redundant lines of an electric meter box, and the winding method includes the following steps:

[0059] The storage tube 1 is fixed to the bottom of the inner cavity of the meter box through a clamping seat, and the bottom end of the redundant wire is inserted into the clamping ring 32 through the ceramic tube 11;

[0060] The rotating rod 2 is rotated by the rotating assembly 22, and the rotating rod 2 drives the bevel gear ring 31 to rotate through the clamp 21, and the bevel gear ring 31 drives the winding wheel 3 to rotate and rewind the wire;

[0061] After the wire is completely wound up by the winding wheel 3, the wire will generate a pulling force on the winding wheel 3. At this time, the clamp 21 moves through the spring shaft 24 and no longer drives the winding wheel 3 to rotate through the bevel gear ring 31. Instead, the rotating rod 2 will continue to drive the other winding wheel 3 to rotate and wind up other wires. When the other wires are completely wound up, the rotating rod 2 stops rotating.

[0062] When the wire needs to be pulled out from the inside of the storage tube 1, the screw 27 is rotated counterclockwise. The screw 27 rotates, and the limit block 25 is pulled toward the inside of the rotating rod 2 through the pull rope 28. The limit block 25 pulls the clamping member 21 away from the bevel gear ring 31 through the bracket 23, so that the end of the clamping member 21 is separated from the tooth groove of the bevel gear ring 31;

[0063] When the wire needs to be rewound, the screw 27 is rotated clockwise, the pull rope 28 is not under force, and the elastic rib 26 drives the limit block 25 to move toward the inner wall of the rotating rod 2 through its own elasticity. The limit block 25 drives the clamping member 21 to reset through the bracket 23, and the end of the clamping member 21 is re-embedded in the bevel gear ring 31 to rewind the wire.
