Description

Technical Field

[0001] This utility model relates to the field of wire winding device technology, and in particular to a wire winding reel. Background Technology

[0002] Portable or non-portable cleaning equipment typically includes an internal cord reel to house the power cable and allow it to be pulled out and held in place. Taking a canister vacuum cleaner as an example, to enable movement over a wide area while performing vacuuming operations, the power cable, which can be pulled out, is housed in the reel's rotating disc for external AC power. Its internal end is electrically connected to the control circuit board inside the vacuum cleaner. A movable support is mounted on the fixed disc of the cord reel, and a stop wheel mounted on the movable support abuts against the rotating disc to keep it in a limited and locked state. However, the stop wheel, being a rotatable wheel structure, relies solely on the movable support as the component that causes the stop wheel to abut against the rotating disc, resulting in insufficient structural stability. Especially after long-term use, the path of the movable support's back-and-forth movement increases due to wear, inevitably causing gaps to form between the outer edge of the stop wheel and the outer or inner wall of the rotating disc. Therefore, a more stable and reliable limiting structure is desired to effectively solve the above-mentioned technical problems. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, a winding reel is provided, which can achieve the technical purpose of limiting the rotation of the rotating disk and unlocking the locked state of the rotating disk. The overall structure is simpler and more reliable, and the braking effect is more stable, thereby overcoming at least one of the above-mentioned technical defects.

[0004] The specific technical solution is as follows:

[0005] A cable reel includes a fixed disc, a rotating disc rotatably connected to the fixed disc for winding and storing cables, and a movable support movably disposed on the fixed disc and capable of translation in the radial direction of the fixed disc.

[0006] A lever is also movably mounted on the fixed plate. The lever is hinged to the fixed plate in the middle. At least one end of the lever abuts against the movable bracket, while the other end is rotatably connected to a first stop wheel, which is adjacent to the outer edge of the rotating plate.

[0007] Furthermore, the movable bracket has a first position state in which the first stop wheel abuts against the rotating disk to restrict the free rotation of the rotating disk, and a second position state in which the first stop wheel moves away from the rotating disk to allow the rotating disk to rotate.

[0008] Preferably, the end of the rotating disk facing the fixed disk forms an annular column, and a second stop wheel is rotatably mounted on the front end of the movable bracket, and the second stop wheel is adjacent to the inner wall of the annular column.

[0009] When the movable support is in the first position, the second stop wheel abuts against the inner wall of the annular column, restricting the free rotation of the rotating disk. When the movable support is in the second position, the second stop wheel moves away from the inner wall of the annular column, allowing the rotating disk to rotate.

[0010] Preferably, a coil spring is rotatably mounted on the fixed disk, and the free end of the coil spring is connected to the outer wall of the annular column to cause the rotating disk to return to its original position.

[0011] Preferably, a tension spring is also connected to one end of the lever near the first stop wheel, and the other end of the tension spring is hooked to the movable bracket to provide a force to the lever to cause the first stop wheel to press against the outer wall of the rotating disk.

[0012] Preferably, the movable bracket also has a top block at the rear side of the lever, the front end of the top block abutting against the end of the lever away from the first stop wheel, so as to drive the lever to overcome the preload of the tension spring and rotate around the hinge end when the movable bracket moves forward.

[0013] Preferably, a limiting post is erected on the upper surface of the fixed plate, and a through hole is opened in the middle of the lever to pass through the limiting post, so that the lever can be rotated around the limiting post and is installed on the fixed plate.

[0014] Preferably, the outer periphery of the rotating disk is also arranged in a circumferential array with multiple friction surfaces protruding outward, and when the movable support is in the first position state, the outer edge of the first stop wheel is located on the rotation path of the friction surface.

[0015] Preferably, the inner wall of the annular column is further provided with multiple protrusions that bulge inward, and when the movable bracket is in the first position, the outer edge of the second stop wheel is located on the rotation path of the protrusions.

[0016] Preferably, a groove is formed on the outer peripheral wall of the annular column, and the free end of the coil spring is placed in the groove; a return spring is also provided between the rear end of the fixed plate and the movable bracket to cause the movable bracket to return to its original position.

[0017] Preferably, the movable support is provided with a strip groove extending in the front-back direction on both the left and right sides, and a limiting protrusion is formed on both the left and right sides of the fixed plate, and the limiting protrusion is embedded in the strip groove to limit the maximum stroke of the movable support in the front-back direction.

[0018] The beneficial effects of the above technical solution are as follows:

[0019] The reel includes a fixed disc, a rotating disc, a movable bracket, a lever, and a first stop wheel. The movable bracket drives the lever to rotate around its hinged end. The first stop wheel connected to one end of the lever has positions that are close to and away from the outer edge of the rotating disc during the translation of the movable bracket, thus achieving the technical purpose of limiting the rotation of the rotating disc and unlocking the locked state of the rotating disc. The overall structure is simpler and more reliable, and the braking effect is more stable. Attached Figure Description

[0026] To make the technical means, creative features, achieved objectives and effects of this utility model easier to understand, the following embodiments are described in detail with reference to the accompanying drawings. And the following definitions are provided: Figure 1 The direction in which the movable bracket shown on the paper extends into the fixed plate radially is the back-to-forward direction in this embodiment.

[0027] See Figures 1 to 6 As shown in the figure, the cable reel provided in this embodiment includes a fixed disk 2, a rotating disk 1 rotatably connected to the fixed disk 2 for winding and storing cables, and a movable support 3 movably disposed on the fixed disk 2 and capable of translation in the radial direction of the fixed disk 2; wherein,

[0028] A lever 4 is also movably mounted on the fixed disk 2. The lever 4 is hinged to the fixed disk 2 in the middle. At least one end of the lever 4 abuts against the movable bracket 3, while the other end is rotatably connected to a first stop wheel 5, and the first stop wheel 5 is adjacent to the outer edge of the rotating disk 1.

[0029] Furthermore, the movable bracket 3 has a first position state in which the first stop wheel 5 abuts against the rotating disk 1 to restrict the free rotation of the rotating disk 1, and a second position state in which the first stop wheel 5 moves away from the rotating disk 1 to allow the rotating disk 1 to rotate.

[0030] Based on the above technical solution, the winding reel includes a fixed disc 2, a rotating disc 1, a movable bracket 3, a lever 4, and a first stop wheel 5. The movable bracket 3 drives the lever 4 to rotate around its hinge end. The first stop wheel 5 connected to one end of the lever 4 has a position that is close to and away from the outer edge of the rotating disc 1 during the translation of the movable bracket 3, so as to achieve the technical purpose of limiting the rotation of the rotating disc 1 and unlocking the locked state of the rotating disc 1. The overall structure is simpler and more reliable, and the braking effect is more stable.

[0031] In a preferred embodiment, the end of the rotating disk 1 facing the fixed disk 2 is formed with an annular column 11. The front end of the movable bracket 3 (i.e., the end of the movable bracket 3 adjacent to the center of the fixed disk 2) is also rotatably mounted with a second stop wheel 6. The second stop wheel 6 is adjacent to the inner wall of the annular column 11. When the movable bracket 3 is in the first position, the second stop wheel 6 abuts against the inner wall of the annular column 11 to restrict the free rotation of the rotating disk 1. When the movable bracket 3 is in the second position, the second stop wheel 6 moves away from the inner wall of the annular column 11 and allows the rotating disk 1 to rotate, so as to cooperate with the first stop wheel 5 to restrict and unlock the rotation state of the rotating disk 1.

[0032] As a further preferred embodiment, a coil spring 7 is rotatably mounted on the fixed disk 2, and the free end of the coil spring 7 is connected to the outer wall of the annular column 11 to cause the rotating disk 1 to reset.

[0033] In practical application, the user first moves the movable bracket 3 to the second position by pushing or pulling it, unlocking the rotating disk 1. The user can then pull out the cable wrapped around the outer circumference of the rotating disk 1, causing it to rotate. Simultaneously, the free end of the coil spring 7 wraps around the outer wall of the annular column 11 of the rotating disk 1 in the opposite direction, generating a preload. After the cable has been pulled out to a sufficient length, the user releases or pushes / pulls the movable bracket 3 to move it back to the first position, causing the two stop wheels to press against the rotating disk 1 from both the inner and outer sides, thus limiting its rotation. Similarly, when it is necessary to retract the cable, the user pushes or pulls the movable bracket 3 again to move it back to the second position. Under the preload of the coil spring 7, the rotating disk 1 automatically reverses and resets, and the cable is retracted back to the state wrapped around the outer circumference of the rotating disk 1. The user then releases or pushes / pulls the movable bracket 3 again to move it back to the first position, thus locking and limiting the rotation of the rotating disk 1 once more.

[0034] It is worth noting that the first position of the movable support 3 refers to its initial position, while the second position does not limit its specific translation position. The second position is defined as being able to move the two stop wheels away from the rotating disk 1.

[0035] In a preferred embodiment, a tension spring 8 is also connected to one end of the lever 4 adjacent to the first stop wheel 5. The other end of the tension spring 8 is hooked to the movable bracket 3 to provide a force to the lever 4 to push the first stop wheel 5 against the outer wall of the rotating disk 1. Furthermore, combined with... Figure 5 and Figure 6 As shown, a top block 31 is also formed on the movable bracket 3 at the rear side of the lever 4. The front end of the top block 31 abuts against the end of the lever 4 away from the first stop wheel 5. This is used to drive the lever 4 to overcome the preload of the tension spring 8 and rotate around the hinge end when the movable bracket 3 moves forward, so that the first stop wheel 5 moves away from the rotating disk 1, thereby realizing the switching of stopping and unlocking the rotating disk 1. Furthermore, a limiting post 21 is erected on the upper surface of the fixed disk 2. A through hole 41 is opened in the middle of the lever 4 to pass through the limiting post 21, so that the lever 4 can be rotatably mounted on the fixed disk 2 around the limiting post 21. That is, in this embodiment, the lever 4 is hinged to the fixed disk 2 in a manner similar to a pivot connection, but it can also be hinged by other means such as a hinge.

[0036] As a further preferred embodiment, the outer periphery of the rotating disk 1 is also arranged with a plurality of friction surfaces 12 protruding outward in an outward array. When the movable support 3 is in the first position, the outer edge of the first stop wheel 5 is located on the rotation path of the friction surface 12, resulting in a better stopping effect. Furthermore, the inner wall of the annular column 11 is also formed with a plurality of protrusions 13 protruding inward. When the movable support 3 is in the first position, the outer edge of the second stop wheel 6 is located on the rotation path of the protrusions 13, further enhancing the stopping effect.

[0037] In a preferred embodiment, a groove 14 is formed on the outer peripheral wall of the annular post 11, and the free end 71 of the coil spring 7 is inserted into the groove 14, so as to form a detachable structure. However, the coil spring 7 can also be directly riveted to the outer wall of the annular post 11 with rivets.

[0038] In a preferred embodiment, strip-shaped grooves 32 extending in the front-rear direction are respectively formed on the left and right sides of the movable bracket 3. Limiting protrusions 22 are respectively formed by convexities on the left and right sides of the fixed disk 2, and the limiting protrusions 22 are embedded in the strip-shaped grooves 32 to limit the maximum stroke of the movable bracket 3 in the front-rear direction. That is, the structures of the limiting protrusions 22 and the strip-shaped grooves 32 play a role in limiting the maximum stroke and guiding the movable bracket 3. Further, limiting bumps 23 are respectively formed by convexities on the left and right sides of the fixed disk 2 in the front side direction of the limiting protrusions 22 to further limit the maximum stroke of the movable bracket 3 in the forward direction. Further, a return spring 9 is provided between the rear end of the fixed disk 2 and the movable bracket 3 to urge the movable bracket 3 to reset.

[0039] As a further preferred embodiment, one end of the lever 4 is configured in a clamp plate shape, the first stop wheel 5 is arranged in this clamp plate-shaped structure through the first pin shaft, a frame-shaped bracket that is "mouth"-shaped and penetrates through in the front-rear direction is formed on the lower end surface of the movable bracket 3, and the second only wheel is arranged in this frame-shaped bracket through the second pin shaft to facilitate the installation of each component.

[0040] Specifically, the overall shape of the fixed disk 2 is similar to the existing structure, including a plate-shaped part and a rod-shaped part connected front and back, and at least part of the rod-shaped part extends backward out of the fixed disk 2 and is bent downward from the tail to adapt to the installation of the spring. In this embodiment, the top block 31 is arranged at a position adjacent to its bend.

[0041] In addition, an installation groove for accommodating the scroll spring 7 is formed on the fixed disk 2. The scroll spring 7 is integrally circular ring-shaped and an end cover 72 is provided on the upper end surface. An installation column 22 that passes through the central hole of the scroll spring 7 and is detachably connected to the end cover 72 is erected in the installation groove. In a preferred solution, the free end inside the scroll spring 7 is also connected to the outer peripheral wall of the installation column 22. At the same time, the rotating disk 1 is rotationally connected to the lower end of the fixed disk 2 through a central axis and is coaxial. Copper sheets for electrical connection are also provided on the fixed disk 2 to be electrically connected to the power cable wound on the rotating disk 1. This is a commonly used technology in the art, so the description is omitted here. And this solution is mainly applicable to horizontal vacuum cleaners to facilitate dragging out the power cable to connect to the mains power, but it is also applicable to other cleaning devices or electrical appliances and is not limited thereto.

[0042] The above are only the preferred embodiments of the present invention, which are merely illustrative and not restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
