Description

Technical Field

[0001] The invention relates to the technical field of wire winding, and in particular to a wire taking-up box. Background Art

[0002] A wire retracting box is a device for arranging and releasing wires, and is widely used in various small electrical appliances and tools. Its main function is to neatly retract and release wires to prevent entanglement and damage. Generally speaking, a specific groove is set in the wire retracting box to facilitate the quick retraction and release of the wires through the guidance of the groove. In practical applications, the wire retracting box is not only used to retract and release single wires, but sometimes also needs to retract and release double wires. Single-wire retraction is often seen in some simple electrical connections, such as power cables or signal cables, which usually only require one wire for connection. Double-wire retraction is often used for devices that need to transmit power and signals at the same time, such as dual-channel speakers and headphones. However, the existing wire retracting box adopts the same groove design when retracting and releasing single wires and double wires, allowing the wires to move in the same groove. Although this design can smoothly retract and release single wires, when retracting and releasing double wires, the two wires are very likely to entangle with each other or even get knotted during the retraction and release process. This not only makes the retraction and release of the double wires very difficult, but also increases the risk of damage to the double wires, and brings the user the additional burden of untangling the entangled double wires, resulting in a poor user experience.

[0041] Please refer to Figure 1 As shown, it is a schematic diagram of the structure of the wire receiving box provided in an embodiment of the present invention.

[0042] The present invention provides a wire take-up box, comprising: a housing, a wire take-up reel 20 and a retractable structure; wherein:

[0043] The housing comprises an upper housing 11 and a lower housing 12, wherein the upper housing 11 and the lower housing 12 enclose an inner cavity for accommodating the take-up reel 20, the retractable structure and the double wire 30 in a curled state, a cylinder 13 is arranged on the inner wall of the inner cavity, and the housing is provided with a wire inlet 14 and a wire outlet 15;

[0044] The take-up drum 20 is a cylindrical structure, and the periphery of the cylindrical structure is provided with double annular grooves which are parallel to each other and concentric with the cylindrical structure, and an annular partition plate 213 which is concentric with the cylindrical structure is provided between the double annular grooves, and the cylindrical structure is provided with an inlet through hole 22 and an outlet through hole 23, and a hollow straight tube 24 is provided at the center of the cylindrical structure, and the cylinder 13 extends into the hollow straight tube 24; the take-up drum 20 is used to guide the winding of the double wires 30, and one of the double wires 30 is passed through in turn. After passing through the inlet port 14 and the inlet through hole 22, it is wound around one of the double annular grooves, and then passes through the outlet through hole 23 and the outlet port 15 in sequence and then extends out of the take-up box. The other of the double wires 30 passes through the inlet port 14 and the inlet through hole 22 in sequence and then is wound around the other of the double annular grooves, and then passes through the outlet through hole 23 and the outlet port 15 in sequence and then extends out of the take-up box. The take-up reel 20 is also provided with an installation position for installing the retractable structure.

[0045] The retractable structure includes a coil spring 41, which is coiled around the cylinder 13 and is arranged at the installation position. One end of the coil spring 41 is connected to the cylinder 13, and the other end of the coil spring 41 is connected to the take-up drum 20. Through the stretching and resetting of the coil spring 41, the take-up drum 20 can rotate forward and reverse to achieve synchronous release and synchronous retraction of the double wires 30.

[0046] Specifically, the design of the double annular groove can effectively separate the double wires 30 wound thereon, one of the double wires 30 is wound around one of the double annular grooves 211, and the other of the double wires 30 is wound around the other 212 of the double annular groove, so as to avoid the double wires 30 from being entangled with each other. At the same time, the annular partition 213 arranged between the double annular grooves can further enhance the separation effect of the double wires 30, ensuring that the double wires 30 remain neat and orderly during the synchronous retraction and release process. The greater the depth of the double annular groove and the width of the annular partition 213, the more double wires 30 can be wound, thereby allowing more double wires 30 to be wound therein. However, this depth and width are limited by the size of the inner cavity of the shell and cannot be increased indefinitely. In addition, the double wire 30 can be two completely separated wires, or it can be composed of two partially connected wires. In the latter case, the two wires at one end of the double wire 30 are connected together, while the other end is separated and connected to two different components respectively. At this time, the double wires 30 connected together are curled around the hollow straight tube 24 and are located below the take-up drum 20, and the double wires 30 in a separated state are curled and located in the double annular grooves of the take-up drum 20. The annular partition 213 between the double annular grooves can not only enhance the separation effect of the double wires 30, but also play the role of cutting the double wires 30 connected together, thereby further extending the effective length of the double wires 30 and enabling them to be used more flexibly. It can be seen that the take-up drum 20 optimizes the arrangement of the double wires 30 through a reasonable structural layout, and can meet various different usage requirements. Of course, in actual application, the number of annular grooves and annular partitions 213 can be increased accordingly according to the number of wires to be separated, as long as the effect of stable and effective separation of multiple wires is finally achieved.

[0047] Please refer to Figure 2 and Figure 3 As shown, they are respectively structural explosion diagrams of the wire take-up box provided by an embodiment of the present invention at a first angle and a second angle.

[0048] Specifically, the inlet through hole 22 and the outlet through hole 23 provided on the take-up reel 20 allow the double wire 30 to enter and exit the take-up box, ensuring that the double wire 30 can be smoothly wound on the take-up reel 20. The design of the hollow straight tube 24 provides an additional channel for the cylinder 13, enhancing the stability of the overall structure of the take-up box. In addition, the mounting position on the take-up reel 20 is used to limit the coil spring 41, ensuring that the coil spring 41 is always in the mounting position during operation and remains in a stable state, and can be continuously stretched and reset.

[0049] Please refer to Figure 4 and Figure 5 As shown, they are schematic structural diagrams of an upper shell 11 and a lower shell 12 of a wire take-up box provided in an embodiment of the present invention.

[0050] Specifically, the wire inlet 14 and the wire outlet 15 provided in the housing are used to guide the entry and exit of the double wire 30, ensuring that the double wire 30 can smoothly enter and leave the wire take-up box. The inner wall of the inner cavity is provided with a cylinder 13, which is used to limit other components and guide the path of the double wire 30, assisting the double wire 30 to smoothly complete the synchronous retraction and release process.

[0051] Please refer to Figure 6 and Figure 7 As shown, they are schematic structural diagrams of the first angle and the second angle of the wire take-up reel 20 of the wire take-up box provided in an embodiment of the present invention.

[0052] Specifically, the two ends of the coil spring 41 are respectively connected to the cylinder 13 (i.e., the housing) and the take-up drum 20. One end of the coil spring 41 connected to the housing cannot move, and the other end of the coil spring 41 connected to the take-up drum 20 can rotate synchronously with the take-up drum 20. This connection method allows the take-up drum 20 to apply tension to the coil spring 41 during the stretching of the double wire 30, and also allows the coil spring 41 to apply power to the take-up drum 20 during the resetting process. When the double wire 30 is pulled out, the tension generated causes the take-up drum 20 to start rotating in one direction (forward rotation), thereby releasing the double wire 30. The release of the double wire 30 is synchronous, that is, the two wires are released at the same time. At the same time, the coil spring 41 will be stretched synchronously, and the stretching of the coil spring 41 will cause the elastic potential energy of the coil spring 41 to increase. When the double wire 30 needs to be retracted, the elastic potential energy of the coil spring 41 will reset it and retract it to its original shape. The restoring force of the coil spring 41 will drive the take-up drum 20 to start rotating in the other direction (reverse rotation), thereby synchronously retracting the double wires 30. And due to the design of the coil spring 41, it can ensure that the length and tension of the double wires 30 released and retracted are consistent, avoiding the imbalance of the double wires 30 during the retraction process. Overall, the take-up box ensures the effective separation and synchronous retraction of the double wires 30 through reasonable component layout and design.

[0053] Compared with the prior art, the wire take-up box proposed in this embodiment has a cylindrical structure for the internal wire take-up reel 20, which facilitates the synchronous rotation and release of the double wires 30. The periphery of the cylindrical structure is provided with double annular grooves that are parallel to each other and concentric with the cylindrical structure. During the process of retracting and releasing, the double wires 30 are respectively wound in different annular grooves, which effectively avoids the possibility of the two wires crossing and entangled with each other. Each wire has its own independent space, which can significantly reduce the risk of knotting. In addition, the annular partition 213 provided between the double annular grooves further enhances the separation effect of the double wires 30. This annular partition 213 ensures that the double wires 30 will not interfere with each other during synchronous retraction and release, maintains the smoothness and convenience of the synchronous retraction and release process of the double wires 30, and also provides certain protection for the double wires 30. It can be seen that the wire take-up box effectively solves the problem that the double wires 30 are easily entangled and knotted in the same groove during the synchronous retraction and release process through reasonable structural design and functional configuration, significantly improves the user experience, and reduces the risk of damage to the double wires 30.

[0054] In some embodiments of the present application, two screw mounting holes 16 are disposed opposite to each other on the outer wall of the housing.

[0055] Specifically, the wire receiving box can be conveniently fixed to a specific location or device through the screw mounting hole 16, ensuring that it will not move or fall off due to external force during use. This fixing method improves the stability of the wire receiving box and avoids functional failure due to instability. In addition, by providing the screw mounting hole 16, the user can easily disassemble the wire receiving box for maintenance, making the maintenance process of the wire receiving box easier.

[0056] In some embodiments of the present application, a strip-shaped through groove 131 is radially arranged at the top of the cylinder 13 for embedding one end of the coil spring 41, and the take-up reel 20 is provided with a first column 25 for fixing the other end of the coil spring 41, and the first column 25 is located inside the mounting position and is separated from the inner wall of the mounting position.

[0057] Specifically, the design of the strip-shaped through-slot 131 and the first column 25 can effectively fix the two ends of the coil spring 41 to prevent it from being displaced or falling off during operation. This stability ensures that the coil spring 41 can work normally when stretched and reset, and avoids functional failure caused by looseness. And this fixing method makes the installation and removal of the coil spring 41 easier. The user only needs to insert one end of the coil spring 41 into the strip-shaped through-slot 131 and wrap the other end around the first column 25 to complete the installation, reducing complex operating steps and improving user experience.

[0058] In some embodiments of the present application, the wire take-up reel 20 is provided with a second column 26 for limiting the double wire 30, and the second column 26 is located inside the installation position and is separated from the inner wall of the installation position; after the double wire 30 passes through the wire inlet through hole 22, it vertically passes through the gap between the second column 26 and the inner wall of the installation position, and then extends out from the wire outlet through hole 23.

[0059] Specifically, the gap formed between the second column 26 and the inner wall of the installation position provides a smooth path for the double wire 30. Through the guidance of this path, the double wire 30 can be assisted to quickly form a vertical walking state, which not only saves space but also maintains the neatness of the vertical winding of the double wire 30, ensuring that it is smooth and unobstructed when it is retracted and released. It should be noted that the width of the gap is slightly larger than the vertical thickness of the double wire 30 to facilitate the movement of the double wire 30 in the gap.

[0060] In some embodiments of the present application, the wire take-up box further includes a positioning structure, and the positioning structure includes a first column 121, a second column 122, a third column 111 and a first positioning hole 112;

[0061] The first column 121 is arranged on the outer edge of one of the upper shell 11 and the lower shell 12, the second column 122 is arranged on the top of the first column 121, the width of the second column 122 is smaller than the width of the first column 121, the third column 111 is arranged on the outer edge of the other one of the upper shell 11 and the lower shell 12 at a position corresponding to the first column 121, the first positioning hole 112 is arranged on the top of the third column 111 at a position corresponding to the second column 122, and the widths of the third column 111 and the first column 121 are equal; when the second column 122 is inserted into the first positioning hole 112, the second column 122 and the first positioning hole 112 are interference fit and the first column 121 and the third column 111 are aligned.

[0062] Specifically, the design of the first column 121 and the third column 111 helps the upper shell 11 and the lower shell 12 to achieve preliminary positioning during assembly. The design of the second column 122 and the first positioning hole 112 ensures that the upper shell 11 and the lower shell 12 can be accurately aligned during assembly. When the second column 122 is inserted into the first positioning hole 112, the interference fit design can also effectively maintain a close connection between the two, ensuring the overall structural stability of the shell. Through this positioning structure, the connection between the upper shell 11 and the lower shell 12 is made stronger, allowing the shell to withstand greater external pressure and impact. This enhanced structural strength helps to improve the durability and reliability of the take-up box and extend its service life.

[0063] In some embodiments of the present application, the wire take-up box includes three positioning structures, and an angle of 120 degrees is formed between every two positioning structures.

[0064] Specifically, the three positioning structures are evenly distributed on the outer edge of the shell, and form an angle of 120 degrees between each other. The 120-degree angle design allows the three positioning structures to provide higher positioning accuracy. By setting the positioning points at different angles, it can be ensured that the upper shell 11 and the lower shell 12 can be more accurately aligned during installation, effectively preventing the upper shell 11 and the lower shell 12 from offsetting or moving during use, ensuring that they always stay in the predetermined position, thereby improving the safety and reliability of the use of the wire collection box. In addition, the evenly distributed layout can also enhance the aesthetic appearance of the wire collection box, making the wire collection box more visually harmonious and in line with the aesthetic principles of industrial design.

[0065] In some embodiments of the present application, the upper shell 11 and the lower shell 12 are both circular structures and are concentrically arranged, the inner cavity is a cylindrical cavity, the take-up reel 20 is concentric with the shell, the cylinder 13 is located at the center of the lower shell 12, the lower shell 12 is provided with the wire inlet 14, and the upper shell 11 is provided with the wire outlet 15.

[0066] It should be noted that the above design is only one of the structural solutions of the wire receiving box. In practical applications, the wire receiving box can be subjected to various structural changes according to specific needs, such as adjusting the shape of the shell, changing the positions of the outlet 15 and the inlet 14, etc., to adapt to different application scenarios and user needs. Examples are not given here for further description. In addition, the first column 25 and the second column 26 can both be arc columns, which are concentric with the shell to further maintain the structural consistency of the wire receiving box.

[0067] In some embodiments of the present application, the wire receiving box also includes a screw, a screw hole 132 is set at the center position of the top of the cylinder 13, and the upper shell 11 is provided with a mounting through hole 113. The screw passes through the mounting through hole 113 and the screw hole 132 in sequence to screw the upper shell 11 and the lower shell 12 together.

[0068] Specifically, the screw connection method can simply and effectively fix the upper shell 11 and the lower shell 12 tightly together, enhance the stability of the overall structure of the shell, and prevent loosening or separation during use. When the wire take-up box needs maintenance or overhaul, the screw connection method can also conveniently disassemble and reassemble the shell, reducing the complexity and time cost of maintenance. It should be noted that the screws are not shown in the structural diagram of the wire take-up box shown above. In actual application, the appropriate screw type and specification can be selected according to specific needs to screw the upper shell 11 and the lower shell 12 together to ensure the firmness and safety of the connection.

[0069] Please refer to Figure 8 As shown, it is a schematic diagram of the structure of the track plate 43 of the wire take-up box provided in an embodiment of the present invention.

[0070] In some embodiments of the present application, the wire take-up box further includes a state switching structure, which is disposed in the inner cavity and located above the wire take-up reel 20, and the state switching structure includes a limit groove, a ball 42 and a track plate 43;

[0071] The limiting groove is a strip-shaped groove 114 and is arranged on the inner wall of the upper shell 11;

[0072] The ball bearings 42 are disposed between the track of the track plate 43 and the strip groove 114, and the ball bearings 42 can roll between the track and the strip groove 114;

[0073] A circular through hole 431 is provided at the center of the track disk 43, and the circular through hole 431 is concentric with the take-up disk 20. The cylinder 13 extends into the circular through hole 431. An assembly position for assembling the track disk 43 is also provided above the take-up disk 20. When the track disk 43 is assembled at the assembly position, the track disk 43 can rotate synchronously with the take-up disk 20. The track disk 43 is provided with two outer arc tracks of the same shape, two inner arc tracks of the same shape, two switching tracks of the same shape, and two tracks of the same shape. A locking track, wherein the depth of the rear end of the locking track is greater than the depth of the other tracks, wherein one of the outer arc tracks, one of the inner arc tracks, one of the switching tracks and one of the locking tracks together constitute a first track 436, wherein another of the outer arc tracks, another of the inner arc tracks, another of the switching tracks and another of the locking tracks together constitute a second track 437, wherein the first track 436 and the second track 437 have the same shape and are circumferentially arranged in an array around the circular through hole 431;

[0074] When the ball 42 rolls along one direction of the strip groove 114, the ball 42 can circulate and roll in the inner arc track;

[0075] When the ball 42 rolls along the other direction of the strip groove 114, the ball 42 rolls into the outer arc track through the switching track and can circulate and roll in the outer arc track;

[0076] When the ball 42 switches its rolling direction in the outer arc track and continues to roll along the outer arc track for a distance, the ball 42 rolls into the tail end of the locking track and is limited by the tail end;

[0077] When the ball 42 rolls out from the tail end and switches the rolling direction in the locking track and rolls for a certain distance, the ball 42 rolls back into the inner arc track.

[0078] Specifically, four types of tracks are arranged on the track disk 43, and each of these four types of tracks (outer arc track, inner arc track, switching track and locking track) has two tracks, and the two tracks of the same type are arranged in a circumferential array around the circular through hole 431. One of the outer arc tracks 4321, one of the inner arc tracks 4331, one of the switching tracks 4341 and one of the locking tracks 4351 together constitute the first track 436, and the other 4322 of the outer arc track, the other 4332 of the inner arc track, the other 4342 of the switching track and the other 4352 of the locking track together constitute the second track 437, and the first track 436 and the second track 437 are also arranged in a circumferential array around the circular through hole 431. The ball 42 is a stainless steel ball. In order to facilitate the rolling of the stainless steel ball, lubricating oil can also be filled between the track of the track disk 43 and the strip groove 114 to make the rolling process of the ball 42 smoother. The ball 42 can circulate and roll in the inner arc track in one direction, and relative rotation occurs between the take-up drum 20 and the upper shell 11 where the strip groove 114 is located; when the ball 42 rolls into the outer arc track through the switching track, the ball 42 can circulate and roll in the outer arc track in another direction, and relative rotation also occurs between the take-up drum 20 and the upper shell 11 where the strip groove 114 is located; after the ball 42 turns around and rolls a certain distance in the outer arc track, the ball 42 rolls into the tail end of the locking track, so that the ball 42 cannot continue to roll, and no relative rotation occurs between the take-up drum 20 and the upper shell 11 where the strip groove 114 is located; after the ball 42 turns around and rolls a certain distance in the locking track again, the ball 42 rolls into the inner arc track again.

[0079] Specifically, when the double wire 30 is pulled to a certain length and then retracted a short distance, the ball 42 in the inner arc track rolls from the switching track into the outer arc track, then turns around and rolls into the locking track to get the ball 42 stuck. At this time, the take-up drum 20 will not reverse due to the contraction elastic force of the coil spring 41; the double wire 30 is pulled out again and then released. At this time, the ball 42 rolls from the locking track into the inner arc track and circulates in the inner arc track. At this time, the take-up drum 20 and the track disk 43 rotate together, thereby realizing partial retraction and release of the double wire 30. It can be seen that the track design can realize the synchronous release and retraction of the double wire 30 in the take-up box, and at the same time, it can also realize that when the double wire 30 is pulled out for different distances and then released, the take-up drum 20 can be stuck in different positions, which is suitable for storing double wires 30 of different lengths.

[0080] In some embodiments of the present application, the outer wall of the lower shell 12 is also provided with an arc-shaped slot 123 for vertically inserting the double wire 30. When the double wire 30 is vertically inserted into the arc-shaped slot 123, the double wire 30 and the arc-shaped slot 123 are interference fit.

[0081] Specifically, the double wire 30 is vertically inserted into the arc-shaped slot 123, which can reduce the contact friction between the double wire 30 and the external environment compared to the double wire 30 in the horizontal state, and play a certain protective role for the double wire 30. When the double wire 30 is vertically inserted into the arc-shaped slot 123, an interference fit is formed between the double wire 30 and the arc-shaped slot 123. This design can effectively fix the double wire 30 and prevent accidental loosening or damage caused by pulling during use. The design of the arc-shaped slot 123 can keep the double wire 30 in a certain bending state when stored, avoiding the double wire 30 from being directly stretched or compressed during the storage process, thereby reducing the risk of damage and effectively extending the service life of the double wire 30.

[0082] The wire take-up box provided in this embodiment has a simple structure and is easy to use. It can realize the synchronous and partial retraction and release of the two wires 30, maintain good performance in various usage environments, provide users with an excellent usage experience, and meet the needs of convenience and efficiency in modern life.
