Description

Technical Field

[0001] This invention relates to the field of mechanical structures, specifically to the design of a counting device on a cable reel. Background Technology

[0002] Portable cable reels are used to wind up power cables, signal cables, and data transmission cables. Both ends of the cables must be connected to matching connectors. They are designed for long-distance, field use, and can be repeatedly retracted and extended for easy portability.

[0003] In practical applications, most cable reels lack real-time counting devices, making it impossible to confirm the number of times the cable reel has been deployed and retracted in real-time, as well as the number of times the cable plug has been inserted and removed, i.e., its service life. Therefore, safe use within the service life range cannot be guaranteed. Alternatively, conventional counting methods are complex, requiring two hands, resulting in lengthy operations, cumbersome movements, and extremely inconvenient counting. For special users requiring rapid cable deployment, retraction, removal, and real-time counting during field operations, existing technologies cannot meet the demands. Summary of the Invention

[0004] The purpose of this invention is to design a counting device that can be operated with one hand for cable reel structures. It can count while winding and unwinding cables, effectively solving the problem that cable reels cannot be clearly defined as having reached their lifespan during practical use, and thus continue to be used with defects.

[0005] To solve the above problems, the present invention adopts the following technical solution: A counting device on a cable reel includes a quick-lock connector and a counter connected to the cable reel. The counter includes a housing, a button penetrating inside and outside the housing, a paddle assembly slidingly contacting one end of the button inside the housing, and a counting wheel engaged at one end of the paddle assembly. A first spring is provided between the button and the paddle assembly, and a second spring is provided inside the quick-lock connector. The second spring compresses the button, and the button compresses the first spring to move axially along the paddle assembly. The paddle assembly drives the counting wheel to rotate around the axis.

[0006] In the above technical solution, one end of the button is provided with a socket along the axial direction, and the wall of the socket is provided with an open arc-shaped groove along the axial direction, the groove penetrating the wall of the socket.

[0007] In the above technical solution, one end of the paddle assembly is inserted into the socket and contacts the arc-shaped groove, and the other end of the paddle assembly is inserted into the counting wheel.

[0008] In the above technical solution, the paddle assembly includes: a main shaft, one end of which is fixedly provided with a pin, the pin contacting an arc-shaped groove in the insertion hole, and a dial fixedly connected to the other end of the main shaft, the dial having a protruding paddle along the radial direction, the paddle engaging with the counting wheel.

[0009] In the above technical solution, the inner wall of the counting wheel is provided with a number of locking teeth along the circumference, and the locking teeth are engaged with the paddle.

[0010] In the above technical solution, a set of positioning keys is provided on one side of the dial, and the positioning element limits the rotation angle of the dial in the counting wheel.

[0011] The above technical solution includes multiple counting wheels, and a linkage gear is provided between every two counting wheels. The linkage gear can engage and disengage with the two adjacent counting wheels.

[0012] In the above technical solution, a convex key is provided on one side of the counting wheel, and a keyway is provided on the linkage gear, and the convex tooth and the keyway can engage.

[0013] In the above technical solution, the minimum elastic force of the second spring is greater than the maximum elastic force of the first spring.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: This invention effectively solves the problem of cable reels continuing to be used despite defects due to the inability to clearly determine their lifespan during practical use, while also ensuring temporary use within their service life. The counting method is simple to operate, requiring no additional steps and maintaining the existing one-handed cable plug insertion / removal operation. Counting occurs instantly during the operation, eliminating the omissions and errors that occur with other counting methods. It is particularly suitable for the rapid communication or power transmission needs of field operations. Attached Figure Description

Detailed Implementation

[0016] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0017] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features for a similar purpose, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0018] like Figure 1 As shown, this embodiment includes a quick-lock connector 1 and a counter structure. A second spring 11 is provided inside the cavity of the quick-lock connector 1. The second spring 11 is used to apply force to the button of the counter. A locking sleeve is provided on the quick-lock connector 1, which can realize quick operation with one hand.

[0019] The counter structure includes a housing support frame. A button 2 is disposed within the housing support frame, extending through both the inside and outside of the housing. The outer end of the button 2 is used to connect with a quick-lock connector 1. Inside the housing, one end of the button 2 contacts a paddle assembly 4. A first spring 3 is disposed between the paddle assembly 4 and the button 2, utilizing the elastic force of the first spring 3 to change the movement of the button 2 and the paddle assembly 4. The other end of the paddle assembly 4 is connected to a counting wheel 5, driving the counting wheel 5 to rotate.

[0020] like Figure 3 As shown, one end of button 2 is provided with a socket structure, and an arc-shaped groove 21 is provided on the wall surface along the axial direction of the socket structure. The groove 21 is an open structure that penetrates the inside and outside of the socket wall. A baffle is provided at the bottom end of the socket structure to limit the first spring 3.

[0021] like Figure 4 As shown, the paddle assembly 4 includes a main shaft 45, a pin 41 is provided on one end of the main shaft 45, the pin 41 is perpendicularly connected to the main shaft 45, a dial 44 is provided on the other end of the main shaft 45, and a protruding paddle 42 is provided on the radial side of the dial 44. The paddle 42 is an elastic piece with elasticity.

[0022] When the paddle assembly 4 is connected to the button 2, such as Figure 2 As shown, a first spring 3 is fitted onto the main shaft 45, and then the main shaft 45 is inserted into the socket of the button 2, so that the pin 41 can slide along the slide groove 21. When the button 2 axially compresses the first spring 3, the pin 41 slides along the arc-shaped slide groove 21, causing the main shaft 45 to rotate along the arc of the slide groove, thereby driving the dial 44 to rotate.

[0023] To ensure the rotation angle of the dial 44, a positioning element 43 is provided on one side of the dial 44, so that the dial 44 can only rotate at a limited angle.

[0024] like Figure 5 As shown, the counting wheel 5 has a ring-shaped structure. Ten teeth 51 are arranged along the circumference on the inner wall of the counting wheel 5. When the dial 44 is inserted into the counting wheel 5, the dial 42 and the teeth 51 are interlocked. The teeth 51 are designed as an involute structure. The dial 42 is held in place by elastic force on one of the teeth 51. Rotating the dial 42 can cause the dial 42 to move along the involute surface into the next tooth 51.

[0025] This embodiment includes three counting wheels 5, with a set of linkage gears between every two counting wheels 5. Each counting wheel 5 has a protruding key 52 on its side for meshing with the linkage gears. The linkage gears include a primary gear 6 and a secondary gear 7, with key sleeves 61 and 71 respectively provided at different positions on the two gears according to the rotation requirements.

[0026] The specific working process of the entire counting device is as follows: Press button 2 using quick-lock connector 1. Button 2 moves axially, causing the paddle assembly 4 to rotate. The paddle assembly 4 then causes the counting wheel 5 (units digit) to start rotating.

[0027] Each time button 2 is pressed, the counting wheel 5 (units digit) rotates once. When the counting wheel 5 rotates to the tenth time, the protruding key 52 on the counting wheel 5 (units digit) engages with the key sleeve 61 on the first-stage gear 6. When the counting wheel 5 (units digit) rotates again, the first-stage gear 6 rotates synchronously, driving the second-stage gear 7 to rotate. The second-stage gear 7 then drives the second counting wheel 5 (tens digit) to rotate.

[0028] When the counting is complete, the protruding key 52 on the counting wheel 5 (units digit) and the key sleeve 61 on the first gear 6 are misaligned. The counting wheel 5 (tens digit) remains unchanged. It takes ten rotations of the counting wheel 5 (units digit) for the protruding key 52 and the key sleeve 61 to mesh.

[0029] Similarly, using the same structure to perform transmission counting between counting wheel 5 (tens digit) and counting wheel 5 (hundreds digit), this embodiment can count a total of 599 times.

[0030] In this embodiment, the minimum elastic force of the second spring 11 in the quick-lock connector 1 is greater than the maximum elastic force of the first spring 3, ensuring that the second spring 11 can separate from the counting structure after unlocking, and ensuring that the button used for counting can drive the counting wheel to rotate.

[0031] This invention is not limited to the specific embodiments described above. The invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
