Description

Technical Field

[0002] Canister or upright vacuum cleaners typically have a cord reel inside to house the power cord and allow it to be pulled out and held in place. For easy movement and vacuuming, the power cord, which can be pulled out and housed in the reel's rotating disc, is used for external AC power and its internal end is electrically connected to the control circuit board inside the vacuum cleaner. To achieve this, the cord reel usually includes a fixed disc mounted inside the vacuum cleaner and a rotating disc rotatably connected to the fixed disc. Furthermore, to allow the cord to be pulled out and to lock it in place, a restraining component is usually designed on the fixed disc to lock the rotation of the rotating disc.

[0003] In the current solution, the limiting component is usually a movable bracket with a spring return function. The rotating disk is locked and unlocked by moving the movable bracket. After long-term use, the limiting effect is easily affected by wear or aging. At the same time, the structure is relatively complicated and not convenient to disassemble and assemble.

[0007] The limiting assembly includes a first limiting member and a second limiting member arranged adjacent to each other and respectively hinged to the fixed disk, and an elastic member for causing the first limiting member and the second limiting member to reset. The adjacent ends of the first limiting member and the second limiting member abut against each other and the opposite ends of the first limiting member and the second limiting member respectively form a limiting part that abuts against the outer wall of the rotating disk.

[0008] Furthermore, pushing the adjacent ends of the two limiting members can cause the two limiting parts to rotate synchronously in a direction away from the outer wall of the rotating disk, thereby releasing the limiting state of the rotating disk. The elastic element is used to cause the two limiting members to return to the position state that limits the rotation of the rotating disk.

[0009] Preferably, the first limiting member and the second limiting member are both hinged to the fixed plate at the middle, and a limiting wheel is rotatably connected to the end of the first limiting member away from the second limiting member, and the limiting wheel serves as the limiting part of the first limiting member;

[0014] Preferably, the lower end face of the lower turntable is recessed to form a mounting groove for accommodating the coil spring, and the open end of the mounting groove is closed by the lower end cover, so that the coil spring is housed between the lower turntable and the lower end cover.

[0015] Preferably, the end of the connecting shaft is configured as a hollow shaft structure with a notch, and the free end of the coil spring on the inward side is inserted into the notch.

[0016] Preferably, the fixed plate includes a main body with a through hole in the middle, a connecting plate fixed in the through hole, and a connecting shaft integrally formed on the connecting plate.

[0032] 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. The direction from the rotating disk to the fixed disk is defined as the upward direction in this embodiment, and the radially inward direction on the fixed disk is defined as the inward direction in this embodiment.

[0033] See Figures 1 to 8 As shown in the figure, the winding wheel provided in this embodiment includes a fixed disk 1 and a rotating disk 2 rotatably connected to the fixed disk 1 for winding and storing cables. A limiting component 3 is also installed on the fixed disk 1 to limit the rotation of the rotating disk 2.

[0034] The limiting component 3 includes a first limiting member 4 and a second limiting member 5 arranged adjacent to each other and respectively hinged to the fixed disk 1, and an elastic member 6 for causing the first limiting member 4 and the second limiting member 5 to reset. The first limiting member 4 and the second limiting member 5 have adjacent ends that abut against each other and opposite ends that respectively form a limiting part that abuts against the outer wall of the rotating disk 2.

[0035] Furthermore, pushing one end of the two limiting members can cause the two limiting parts to rotate synchronously in a direction away from the outer wall of the rotating disk 2, thereby releasing the limiting state of the rotating disk 2. The elastic member 6 is used to cause the two limiting members to return to the position state that limits the rotation of the rotating disk 2.

[0036] Based on the above technical solution, the winding wheel includes a fixed disk 1, a rotating disk 2, and a limiting component 3. The limiting component 3 includes a first limiting member 4, a second limiting member 5, and an elastic member 6. By pushing, the two limiting members can be made to rotate synchronously around the hinge end to release the limiting state of the rotating disk 2. After being released, the elastic member 6 causes the two limiting members to return to the position that limits the rotation of the rotating disk 2. The overall structure is simple, easy to disassemble and assemble, and has a good effect in limiting rotation.

[0037] In a preferred embodiment, both the first limiting member 4 and the second limiting member 5 are hinged to the fixed disk 1 at their center. A limiting wheel 13 is rotatably connected to the end of the first limiting member 4 facing away from the second limiting member 5, serving as the limiting portion of the first limiting member 4. The end of the second limiting member 5 facing away from the first limiting member 4 has a protruding ridge 14 facing the outer wall of the rotating disk 2, also serving as the limiting portion of the second limiting member 5. Further, the end of the first limiting member 4 adjacent to the second limiting member 5 has a first protruding post 23 formed inwardly for connecting the elastic member 6. The end of the second limiting member 5 adjacent to the first limiting member 4 abuts against the outer wall of the first limiting member 4, such that pressing the outer wall of the end of the second limiting member 5 adjacent to the first limiting member 4 can drive both limiting members to rotate synchronously around the hinged end. Specifically, both limiting members have a central opening and are hinged to the fixed disk 1 by a through-pin, and the elastic member 6 is preferably a spring. Furthermore, the second limiting member 5 has a step 18 on the inward side of the end adjacent to the first limiting member 4, and the first limiting member 4 at least partially abuts against the step 18 to prevent the two limiting members from separating after repeated use.

[0038] In a further embodiment, the fixed disk 1 has a radially extending strip groove 24, and the first limiting member 4 also has an upwardly extending protruding plate 22. A first protruding post 23 is formed on the protruding plate 22, and a second protruding post 25 is also provided on the inward side wall of the strip groove 24. The protruding plate 22 extends at least partially into the strip groove 24, and the two ends of the elastic member 6 are respectively connected to the first protruding post 23 and the second protruding post 25 to limit the maximum stroke of the first limiting member 4. Furthermore, the outer wall of the rotating disk 2 also has a plurality of friction surfaces 15, and the friction surfaces 15 are formed by a plurality of parallel protruding ribs formed on the outer wall of the rotating disk 2, which are used to enhance the limiting effect of the limiting wheel 13 after contacting it. Furthermore, the fixed disk 1 also has a backing seat 19, which is used to limit the maximum outward stroke of the limiting wheel 13 during the pressing action.

[0039] In a preferred embodiment, the fixed disk 1 has a connecting shaft 8 extending downward in the middle. The rotating disk 2 includes an upper rotating disk 9 and a lower rotating disk 10 that are joined together. Both the upper rotating disk 9 and the lower rotating disk 10 are rotatably mounted on the connecting shaft 8, forming a storage area for winding and storing cables between them. A coil spring 12 wound into a ring shape is also installed in the lower rotating disk 10. The free end of the inner side of the coil spring 12 is connected to the connecting shaft 8, so that when the rotating disk 2 rotates, the free end of the coil spring 12 is wound around the outer circumference of the connecting shaft 8, generating a preload force for reset. Furthermore, the lower end face of the lower rotating disk 10 is recessed to form a mounting groove for accommodating the coil spring. The open end of the mounting groove is closed by a lower end cover 11, so that the coil spring 12 is housed between the lower rotating disk 10 and the lower end cover 11. Furthermore, the end of the connecting shaft 8 is configured as a hollow shaft structure with a notch 20. The free end of the coil spring 12 on the inward side is inserted into the notch 20 for easy installation and to prevent easy removal. However, it can obviously also be achieved by chemical bonding or welding.

[0040] As a further preferred embodiment, the fixed disk 1 includes a main body 7 with a through hole in the middle, a connecting disk 26 fixed in the through hole, and a connecting shaft 8 integrally formed on the connecting disk 26. Positive and negative terminal springs 17 are provided on the end face of the connecting disk 26 facing the rotating disk 2. Two concentrically arranged annular electrical connecting rings 16 are provided in the upper rotating disk 9. The positive and negative terminal springs 17 abut against the two electrical connecting rings 16 respectively, so that the rotating disk 2 is always electrically connected to the positive and negative terminal springs 17 during rotation. The fixed disk 1 also has wires electrically connected to the positive and negative terminal springs 17. The electrical connecting rings 16 are electrically connected to the cable wound on the rotating disk 2 to meet the electrical connection requirements of the winding wheel and to avoid damage to the terminal ends due to excessive winding during cable unwinding and rewinding. Furthermore, the first limiting member 4 and the second limiting member 5 are both installed on the lower end face of the fixed disk 1 and located between the connecting disk 26 and the upper rotating disk 9. Preferably, the upper end face of the upper turntable 9 is formed with an annular column, and both limiting parts abut against the outer wall of the annular column.

[0041] In addition, this solution is mainly applicable to canister or upright vacuum cleaners to facilitate pulling out the power cord for connection to mains power, but it is also applicable to other cleaning equipment or appliances and is not limited to them.
