Description

Technical Field

[0001] This utility model relates to the technical field of vacuum cleaner accessories, and in particular to a compact winding reel. Background Technology

[0002] Vacuum cleaners, especially canister vacuums, typically require an internal cord reel to hold the power cable, allowing for movement over a wide area while performing vacuuming operations. The power cable is primarily used for external AC power, and its internal end is electrically connected to the control circuit board inside the vacuum cleaner. This cord reel usually needs to meet technical requirements such as being able to wind and store the cable, facilitating its extension and retraction, and maintaining the cable in an extended position.

[0003] In the current solution, after the winding wheel rotates and produces the wire, it is generally achieved to automatically rotate and reset by setting a coil spring on the fixed plate of the winding wheel. In the current design, the coil spring is mainly installed in an additional housing configured outside the fixed plate, or assembled in a cavity structure inside the fixed plate. This makes the overall structure of the winding wheel relatively bulky and difficult to achieve the goal of a compact structure. Utility Model Content

[0004] In view of the above-mentioned problems in the prior art, a compact winding wheel is provided, which integrates the coil spring into the whole consisting of the rotating disk and the mounting disk. It eliminates the need for an additional housing for mounting the coil spring on the outside of the fixed disk, and also eliminates the need for the coil spring assembly to be configured in a cavity structure inside the fixed disk. This makes the overall structure of the winding wheel simpler, more reliable and compact, thereby overcoming at least one of the above-mentioned technical defects.

[0005] The specific technical solution is as follows:

[0006] A compact winding reel, used in vacuum cleaners, comprises:

[0007] Fixed plate;

[0008] The rotating disk has an outer periphery that forms a storage area for winding cables.

[0009] The mounting plate is assembled on the upper surface of the rotating disk, and the rotating disk and the mounting plate are mounted on the lower end of the fixed disk so that they can rotate synchronously.

[0010] The coil spring is circular in shape and is arranged between the mounting plate and the rotating plate. The free end of the coil spring on the inward side is connected to the fixed plate, which is used to drive the rotating plate and the mounting plate to reset.

[0011] Preferably, an annular receiving area is formed between the mounting plate and the rotating plate, and a coil spring is disposed within the annular receiving area, with the outer edge of the coil spring at least partially in contact with the mounting plate and / or the rotating plate.

[0012] Preferably, the lower end face of the fixed plate extends downward to form a first annular post, and the free end of the coil spring is detachably connected to the outer wall of the first annular post.

[0013] Preferably, the outer wall of the first annular column has a limiting rib extending in an upward direction, and there is a gap between the limiting rib and the outer wall of the first annular column, the free end of the coil spring is held in the gap, so that the coil spring can be detached from the connecting fixing plate.

[0014] Preferably, a plurality of limiting blocks are formed on the wall of the lower end face of the mounting plate extending inward, and the upper end face of the rotating plate has a number of grooves that are opposite to the limiting blocks and are positioned opposite each other, and each limiting block is at least partially embedded in the groove.

[0015] Preferably, the upper end face of the rotating disk is formed with a mounting groove, the mounting disk is at least partially embedded in the mounting groove, and the lower end face of the mounting disk is formed with a receiving groove, and the receiving groove and the mounting groove together form an annular receiving area. The upper end face of the limiting block abuts against the coil spring, so that the coil spring is limited to the receiving groove.

[0016] Preferably, a movable bracket is movably provided on the upper surface of the fixed plate. The movable bracket has a limit wheel at its front end and has a first movable position that causes the limit wheel to be in close contact with the rotating plate and restricts the rotation of the rotating plate, and a second movable position that causes the limit wheel to be away from the rotating plate and allows the rotating plate to rotate.

[0017] Preferably, the upper end face of the rotating disk also has a second annular column that protrudes upward in an annular shape, and the second annular column extends upward into the fixed disk. When the movable bracket is in the first movable position, the outer edge of the limiting wheel abuts against the inner wall of the second annular column.

[0018] Preferably, the upper end face of the fixed plate is also provided with a rotatable limiting member, and when the movable bracket is in the first movable position, the movable bracket pushes the limiting member to rotate to a position that at least partially abuts against the upper edge of the second annular column. When the movable bracket is in the second movable position, the limiting member is reset to a position away from the upper edge of the second annular column.

[0019] The beneficial effects of the above technical solution are as follows:

[0020] The compact winding wheel provided in this embodiment includes a fixed disk, a rotating disk, a mounting disk, and a coil spring. The rotating disk and the mounting disk are rotatably mounted on the fixed disk after assembly. The coil spring is annular and is disposed between the rotating disk and the mounting disk. Its free end is also connected to the fixed disk, which enables the technical purpose of causing the rotating disk to return to its original position. At the same time, it is integrated into the whole formed by the rotating disk and the mounting disk, eliminating the need for an additional housing for mounting the coil spring on the outside of the fixed disk, and eliminating the need for a coil spring assembly with a cavity structure inside the fixed disk. This makes the overall structure of the winding wheel simpler, more reliable, and more compact. Attached Figure Description

[0028] 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 5 The right-to-left direction shown on the paper is the back-to-front direction in this embodiment, and the up-down direction shown is the up-down direction in this embodiment.

[0029] See Figures 1 to 7 As shown in the illustration, the compact winding reel provided in this embodiment is used in a vacuum cleaner and includes:

[0030] Fixed plate 1;

[0031] The rotating disk 2 has an outer periphery that forms a storage area for winding cables;

[0032] Mounting plate 3 is mounted on the upper surface of rotating plate 2, and rotating plate 2 and mounting plate 3 are mounted on the lower end of fixed plate 1, which can rotate synchronously.

[0033] The coil spring 4 is circular in shape and is arranged between the mounting plate 3 and the rotating plate 2. The free end 41 of the coil spring 4 on the inward side is connected to the fixed plate 1 to drive the rotating plate 2 and the mounting plate 3 to reset.

[0034] In practical applications, when the cable is pulled out, the rotating disk 2 and the mounting disk 3 rotate synchronously, causing the free end 41 of the coil spring 4 to wrap around the fixed disk 1. When the rotating disk 2 and the mounting disk 3 are released from their limits, the coil spring 4 drives the rotating disk and the mounting disk 3 to reset synchronously.

[0035] Based on the above, the compact winding wheel provided in this embodiment includes a fixed disk 1, a rotating disk 2, a mounting disk 3, and a coil spring 4. The rotating disk 2 and the mounting disk 3 are rotatably mounted on the fixed disk 1 after being assembled together. The coil spring 4 is annular and is disposed between the rotating disk 2 and the mounting disk 3. Its free end 41 is also connected to the fixed disk 1, which enables the technical purpose of causing the rotating disk 2 to reset. At the same time, it is integrated into the whole formed by the rotating disk 2 and the mounting disk 3. There is no need to configure an additional shell for mounting the coil spring 4 outside the fixed disk 1, nor is it necessary to configure the coil spring 4 assembly in a cavity structure inside the fixed disk 1, so that the overall structure of the winding wheel is simpler, more reliable and compact.

[0036] In a preferred embodiment, an annular receiving area 10 is formed between the mounting plate 3 and the rotating plate 2, and a coil spring 4 is disposed within the annular receiving area 10, with the outer edge of the coil spring 4 at least partially in contact with the mounting plate 3 and / or the rotating plate 2. Further, combined with... Figure 3 As shown, a first annular post 11 extends downward from the lower end face of the fixed disk 1, and the free end 41 of the coil spring 4 is detachably connected to the outer wall of the first annular post 11. Furthermore, a limiting rib 12 extending upward is provided on the outer wall of the first annular post 11, and a gap exists between the limiting rib 12 and the outer wall of the first annular post 11. The free end 41 of the coil spring 4 is engaged within this gap, allowing the coil spring 4 to be detachably connected to the fixed disk 1.

[0037] In a preferred embodiment, specifically as follows: Figure 3 , Figure 6 and Figure 7 As shown, multiple limiting blocks 31 extend inwardly from the lower end face of the mounting plate 3. The upper end face of the rotating plate 2 has grooves 22 of the same number and position as the limiting blocks 31, and each limiting block 31 is at least partially embedded in the groove 22, so that the mounting plate 3 and the rotating plate 2 rotate synchronously without generating a relative rotational displacement difference, thus achieving the limiting function. Furthermore, the upper end face of the rotating plate 2 forms a mounting groove, and the mounting plate 3 is at least partially embedded in the mounting groove. The lower end face of the mounting plate 3 forms a receiving groove, and the receiving groove and the mounting groove together form an annular receiving area 10. The upper end face of the limiting block 31 abuts against the coil spring 4, so that the coil spring 4 is confined within the receiving groove.

[0038] In a preferred embodiment, a movable bracket 5 is movably disposed on the upper surface of the fixed disk 1. A limiting wheel 7 is disposed at the front end of the movable bracket 5. The movable bracket 5 has a first movable position that causes the limiting wheel 7 to be in close contact with the rotating disk 2 and restricts the rotation of the rotating disk 2, and a second movable position that causes the limiting wheel 7 to be away from the rotating disk 2 and allows the rotating disk 2 to rotate, thereby realizing the locking and unlocking of the rotation of the rotating disk 2.

[0039] As a further preferred embodiment, the upper surface of the rotating disk 2 is further annularly protruding with a second annular post 21, which extends upward into the fixed disk 1. When the movable bracket 5 is in the first movable position, the outer edge of the limiting wheel 7 abuts against the inner wall of the second annular post 21. Furthermore, the upper surface of the fixed disk 1 is also provided with a rotatable limiting member 6. When the movable bracket 5 is in the first movable position, the movable bracket 5 pushes the limiting member 6 to rotate to a position at least partially abutting against the upper edge of the second annular post 21. When the movable bracket 5 is in the second movable position, the limiting member 6 returns to a position away from the upper edge of the second annular post 21.

[0040] Specifically, the upper edge of the second annular post 21 is formed with at least one V-shaped groove. When the movable support 5 is in the first movable position, the front end of the limiting member 6 extends at least partially into the V-shaped groove to limit the circumferential rotation of the turntable. When the movable support 5 is in the first movable position, the limiting wheel 7 abuts against the inner wall of the second annular post 21. When the movable support 5 is in the second movable position, the limiting wheel 7 moves away from the inner wall of the second annular post 21. The inner wall of the second annular post 21 is also recessed to form at least one slot. When the movable support 5 is in the first movable position, the limiting wheel 7 is at least partially engaged in the slot, thereby limiting the turntable together with the limiting member 6 to obtain a more stable and reliable limiting structure. The upper surface of the fixed disk 1 forms a slot for accommodating the limiting member 6. Pivoting holes are respectively provided on the side walls of opposite sides of the slot. The limiting member 6 has connecting shafts on opposite sides that match the shape and position of the pivot holes. The connecting shafts are pivotally connected to the pivot holes, allowing the limiting member 6 to rotate around the axes of the two connecting shafts. A first spring is vertically arranged on the bottom surface of the slot. The upper end of the first spring abuts against the limiting member 6, providing an elastic force to the limiting member 6 to cause its front end to rotate and approach the upper edge of the second annular column 21. A second spring is also provided on the outer wall of the fixed disk 1 to cause the movable support 5 to return to its rearward position. The side of the second spring away from the fixed disk 11 abuts against the movable support 5. This achieves the purpose of free rotation, locking, and resetting of the rotating disk 2 of the winding wheel.

[0041] In addition, this solution is mainly used in canister vacuum cleaners as a power cable storage device to allow the vacuum cleaner to be moved to a more distant location, but it can obviously also be applied to other vacuuming equipment or home appliances.

[0042] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
