Description

Technical Field

[0001] This utility model relates to the field of power energy storage technology, and in particular to a retractable line for power energy storage. Background Technology

[0002] In the booming field of power energy storage, reliable and adaptable connection lines are the core elements to ensure the efficient operation of various energy storage devices. To meet diverse application needs, some power energy storage lines are designed with telescopic functions. Under normal conditions, these lines are retracted by a spring mechanism. When in use, the line needs to be manually pulled to overcome the tension of the spring to adjust the length. This design does indeed make it convenient for users to flexibly adjust the line length according to the actual scenario.

[0003] However, existing technologies have obvious drawbacks. Because the lines are subjected to tension applied by the spring for a long time after connection, the line ports become stress concentration points. The continuous stress can easily cause the insulation layer at the line ports to break, which in turn can lead to the breakage of internal conductors. This not only affects the conductivity of the lines and causes unstable power transmission, but may also cause safety accidents such as short circuits, seriously threatening the normal operation of the entire power storage system.

[0031] Example 1

[0032] Reference Figures 1-6 This is the first embodiment of the present invention. This embodiment provides a retractable power storage line. The retractable power storage line includes a locking component 200. The locking component 200 effectively solves the problem that the line port is easily damaged and broken due to long-term stress in the prior art.

[0033] The main structure 100 includes a housing 101, an inner cavity of which is provided with a spring-loaded disc 102, and a wire 103 fixedly connected to the surface of the spring-loaded disc 102. Telescopic openings 104 are provided on both sides of the housing 101, and the telescopic openings 104 cooperate with the wire 103; and...

[0034] The locking assembly 200 includes a disc 201 connected to the bottom of the housing 101. The bottom of the mainspring rotating disc 102 is rotatably connected to the disc 201. An annular toothed plate 202 is fixedly connected to the bottom of the surface of the mainspring rotating disc 102. A fixing toothed plate 203 is provided on one side of the annular toothed plate 202. A pressing plate 204 is fixedly connected to one side of the fixing toothed plate 203. A through groove 205 is opened on one side of the disc 201. The through groove 205 cooperates with the pressing plate 204. A limit member 206 is provided in the inner cavity of the through groove 205. A support member 207 is provided at the bottom of the fixing toothed plate 203. Sliding members 208 are provided on both sides of the fixing toothed plate 203.

[0035] In the main structure 100, the shell 101 serves as the overall support component. The spring-loaded rotating disk 102 inside its cavity can retract the wire 103 when it is not in use. The telescopic port 104 facilitates the entry and exit of the wire 103. In the locking component 200, the disc 201 is rotatably connected to the spring-loaded rotating disk 102. The annular toothed plate 202 cooperates with the fixed toothed plate 203 to lock the spring-loaded rotating disk 102. The pressing plate 204 can control the position of the fixed toothed plate 203. The through groove 205 provides movement space for the pressing plate 204. This design can realize the telescopic function of the wire 103 and can also lock the length of the wire 103 through the locking component 200, avoiding the line from being subjected to the spring tension for a long time, protecting the line port, and improving the stability and safety of the power storage system.

[0036] Example 2

[0037] Reference Figures 1-6 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0038] Specifically, the limiting member 206 includes limiting grooves 206a opened on both sides of the through groove 205, and a limiting block 206b is slidably connected to the inner cavity of the limiting groove 206a. The end of the limiting block 206b is arc-shaped, and the limiting block 206b cooperates with the pressing plate 204.

[0039] The limiting groove 206a provides sliding space for the limiting block 206b. The limiting block 206b with an arc-shaped end cooperates with the pressing plate 204. When the pressing plate 204 moves, the limiting block 206b can slide in the limiting groove 206a and lock the pressing plate 204, ensuring the stable engagement or disengagement of the fixed toothed plate 203 and the annular toothed plate 202, preventing locking or unlocking failure due to accidental movement during use, and ensuring the reliability of line length adjustment and locking operations.

[0040] Specifically, a first spring 206c is fixedly connected to one side of the limiting block 206b, and one side of the first spring 206c is fixedly connected to the limiting groove 206a.

[0041] When the pressing plate 204 presses the limiting block 206b, the first spring 206c is compressed, and the limiting block 206b can slide within the limiting groove 206a. When the pressing plate 204 moves to the appropriate position, the elastic force of the first spring 206c causes the limiting block 206b to reset and lock the pressing plate 204. This ensures that the limiting block 206b can flexibly limit and unlock the pressing plate 204, making the line length adjustment and locking operation smoother.

[0042] Specifically, the support member 207 includes a support rod 207a fixedly connected to the bottom of the fixed toothed plate 203, and a second spring 207b fixedly connected to the bottom of the support rod 207a. The second spring 207b is fixedly connected to the bottom of the inner cavity of the disc 201.

[0043] The fixed toothed plate 203 and the second spring 207b are connected by the support rod 207a. The elastic force of the second spring 207b makes the fixed toothed plate 203 and the annular toothed plate 202 mesh tightly, thereby effectively limiting the mainspring rotating disk 102. This ensures that the mainspring rotating disk 102 will not easily rotate due to external force in the locked state, preventing the circuit from being subjected to the mainspring tension again and protecting the circuit port.

[0044] Specifically, a support cylinder 207c is slidably connected to the surface of the support rod 207a, and the support cylinder 207c is fixedly connected to the bottom of the inner cavity of the disc 201.

[0045] During the extension and retraction of the second spring 207b, the support cylinder 207c can prevent the support rod 207a from shaking or shifting, ensuring that the support rod 207a can stably support the fixed tooth plate 203, making the meshing between the fixed tooth plate 203 and the annular tooth plate 202 more stable and reliable, and further improving the effect of line locking.

[0046] Specifically, there are multiple sets of support rods 207a, second springs 207b, and support cylinders 207c, which are evenly distributed at the bottom of the fixed toothed plate 203.

[0047] Multiple sets of support rods 207a, second springs 207b, and support cylinders 207c, evenly distributed at the bottom of the fixed toothed plate 203, enable the fixed toothed plate 203 to receive more uniform support force. This ensures that when the fixed toothed plate 203 meshes with the annular toothed plate 202, the force on each part is balanced, avoiding loose meshing or damage due to uneven local force, thereby improving the service life and stability of the locking assembly 200.

[0048] Specifically, the slider 208 includes a slider 208a fixedly connected to the other side of the fixed toothed plate 203. There are two sets of sliders 208a, which are symmetrically distributed on both sides of the fixed toothed plate 203.

[0049] The two sets of symmetrically distributed sliders 208a make the fixed toothed plate 203 move more smoothly and avoid tilting or jamming. This helps the fixed toothed plate 203 to accurately engage or disengage with the annular toothed plate 202, improving the accuracy of line length adjustment and locking operations.

[0050] Specifically, grooves 208b are provided on both sides of the inner cavity of the disc 201, and the grooves 208b cooperate with the slider 208a.

[0051] The slide groove 208b cooperates with the slider 208a to provide a sliding track for the slider 208a. It ensures that the slider 208a can slide along a specific direction, making the movement of the fixed toothed plate 203 smoother and more stable. At the same time, the slide groove 208b also plays a certain limiting role for the slider 208a, preventing the slider 208a from leaving the track and ensuring that the locking component 200 works normally.

[0052] Specifically, a fixing seat 201a is fixedly connected to the bottom of the disc 201, and wire holes are provided on both sides of the fixing seat 201a.

[0053] The main function of the mounting base 201a is to securely connect the housing 101 to other equipment or structures. The cable tie 201b at the bottom is convenient for installation. The cable tie 201b can be connected to the mounting base 201a through the cable tie hole, thereby firmly fixing the entire circuit device in the required position, providing support for the overall mechanism, preventing the circuit from falling due to gravity, and avoiding continuous stress on the circuit port.

[0054] Specifically, a cable tie 201b is provided at the bottom of the fixing base 201a, and the cable tie 201b is fixedly connected to the fixing base 201a through a wire hole.

[0055] Cable tie 201b is tightly connected to fixing base 201a through wire hole, which greatly enhances the fixing effect of housing 101. It can tightly bind housing 101 to other equipment or structure, prevent the line device from loosening or falling off due to vibration, displacement and other factors during long-term use, ensure that the line is always in a stable installation state, and further avoid damage to the line port due to the overall downward force.

[0056] Under normal circumstances, the wire 103 is wound on the mainspring rotating disk 102. The mainspring rotating disk 102 contracts the wire 103 under the action of the mainspring. To adjust the length of the wire 103, an external force is applied to the pressing plate 204. The pressing plate 204 overcomes the elastic force of the first spring 206c and moves in the through groove 205, causing the limiting block 206b to slide in the limiting groove 206a. At the same time, the pressing plate 204 pushes the fixed toothed plate 203 away from the annular toothed plate 202, releasing the lock on the mainspring rotating disk 102. At this time, the wire 103 can be pulled out of the housing 101 through the telescopic port 104, overcoming the tension of the mainspring to achieve length adjustment. When the pressing plate 204 moves to the bottom of the limiting block 206b, the wire is in a state where the length can be freely adjusted.

[0057] After adjusting to the appropriate length, force is applied to the pressing plate 204 again to overcome the elastic force of the first spring 206c. When the pressing plate 204 moves to the top of the limiting block 206b, the elastic force of the second spring 207b pushes the fixed tooth plate 203 to mesh tightly with the annular tooth plate 202 through the support rod 207a, restricting the rotation of the spring-loaded disc 102 and preventing the circuit from being pulled by the spring. During this process, the slider 208a slides smoothly in the groove 208b, ensuring that the fixed tooth plate 203 moves smoothly. The support cylinder 207c provides stable support for the support rod 207a. Finally, the fixing seat 201a is firmly fixed to other equipment or structures through the wire hole with cable tie 201b to prevent the entire device from falling due to gravity and to prevent the circuit port from being continuously stressed.

[0058] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
