Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner technology, and in particular to a self-locking fixing device for vacuum cleaner wiring harnesses. Background Technology

[0002] A vacuum cleaner is a household appliance used to clean dust, dirt, and other debris. It works by generating suction to draw pollutants from the air into a container or bag, thus making the indoor environment cleaner.

[0003] When using a vacuum cleaner, the power cord is usually unplugged, leaving it scattered on the floor, which is messy and makes cleaning the area difficult. When the vacuum cleaner is not in use, the power cord needs to be manually unplugged and neatly coiled into a loop before placing it on the vacuum cleaner or in a designated location. While coiling the cord, one hand needs to hold one end of the cord while the other hand coils it. If the cord is long, this process becomes time-consuming and laborious. Utility Model Content

[0004] To solve the above problems, this utility model provides a self-locking fixing device for vacuum cleaner wiring harnesses.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a self-locking fixing device for a vacuum cleaner cable harness, comprising an installation box disposed at the bottom of the vacuum cleaner body, a cable reel rotatably disposed inside the installation box, a driving component for driving the cable reel to rotate inside the installation box, an installation post disposed at the bottom of the installation box, a square hole being opened on the installation post, a square rod being vertically slidably disposed inside the square hole, a first disc being disposed at the top of the square rod, a compression spring being sleeved on the rod body located between the first disc and the installation post, a second disc being concentrically disposed at the bottom of the cable reel, a plurality of protrusions being circumferentially spaced on the side of the second disc adjacent to the first disc, and a groove being opened on the side of the first disc adjacent to the first disc corresponding to the protrusions, the grooves cooperating with the protrusions, a fixing shell being disposed on one side of the installation box, a round hole for the cable harness to pass through being disposed on one side of the fixing shell, and a fixing component for fixing the cable harness plug being disposed on the outer wall of the installation box near the fixing shell.

[0006] By adopting the above technical solution, an installation box, a cable reel, a first disc, a second disc, a drive assembly, and a fixing assembly are set up. The cable harness is wound inside the reel. When the vacuum cleaner is needed, the cable harness is pulled, causing the reel to rotate, which in turn rotates the second disc. As the second disc rotates, the protrusion slides out of the groove, and the first disc and square rod descend, compressing the compression spring. After the cable harness is pulled to a suitable length, a slight pull causes the protrusion to rotate into the groove. Under the elastic force of the spring, the first disc moves and resets, allowing the protrusion to engage with the groove, limiting the reel and thus limiting the cable harness. The length of the pulled-out cable harness is controllable, preventing the cable harness from becoming tangled and affecting vacuuming in that area. When it is necessary to rewind the cable harness, the drive assembly drives the reel to rotate, rewinding the cable harness. Finally, the fixing assembly secures the cable harness plug, making the process simple and convenient.

[0007] Furthermore, the fixing component includes an arc-shaped slide rail disposed on the outer wall of the mounting box, a sliding seat slidably disposed on the arc-shaped slide rail, and a slot being formed on the sliding seat corresponding to the insert of the wire harness plug.

[0008] By adopting the above technical solution, an arc-shaped slide rail and a sliding seat are set up. After the wire harness is wound up, the plug of the wire harness plug is inserted into the slot to fix the wire harness plug.

[0009] Furthermore, the arc of the vertical cross-section of the protrusion is a minor arc.

[0010] By adopting the above technical solution, it is ensured that the protrusion can slide out of the groove when subjected to external force.

[0011] Furthermore, an electric slip ring is provided on the top of the cord reel, with its lower end connected to the cord reel and its upper end passing through the mounting box and connected to the vacuum cleaner body.

[0012] By adopting the above technical solution and setting an electric slip ring, the wire spool can rotate while the wire harness can still stably deliver power to the vacuum cleaner body.

[0013] Furthermore, a rotating roller is vertically rotatably installed inside the fixed shell on the side adjacent to the mounting box.

[0014] By adopting the above technical solution and setting a rotating roller, the surface of the wire harness comes into contact with the rotating roller when the wire harness moves, thus avoiding scratches on the wire harness.

[0015] Furthermore, a fixing tube is provided at the circular hole of the fixing shell, and a sponge tube is movably disposed inside the fixing tube, the inner diameter of the sponge tube being the same as the diameter of the wire harness.

[0016] By adopting the above technical solution, a fixing tube and a sponge tube are set up. When the wire harness is wound up, the sponge tube wipes away the dust on the surface of the wire harness.

[0017] Furthermore, the fixed tube is spirally provided with a cap with an open end, and a through groove is provided on one side of the sponge tube, the through groove penetrating one side of the sponge tube body.

[0018] By adopting the above technical solution, a tube cap and a through groove are set. The tube cap fixes the sponge tube, and the through groove on the sponge tube makes it easy to break the sponge tube open and pass one side through the wire harness, and then install it in the fixed tube.

[0019] Furthermore, the diameter of the opening is larger than the inner diameter of the sponge tube.

[0020] By adopting the above technical solution, the diameter of the opening is set to be larger than the inner diameter of the sponge tube, so as to avoid the edge of the opening contacting the sponge tube and scratching the wire harness when it is pulled.

[0021] Furthermore, the drive assembly includes a gear ring concentrically arranged at the bottom of the coil, a mounting base is provided inside the mounting box, a drive motor is vertically arranged on the mounting base, and a gear is arranged on the output axis of the drive motor, the gear meshing with the gear ring.

[0022] By adopting the above technical solution, a gear ring, a mounting base, a drive motor, and a gear are set up. The drive motor drives the gear to rotate. Since the gear meshes with the gear ring, the rotation of the gear ring causes the coil to rotate.

[0023] In summary, this utility model has the following beneficial effects: It includes an installation box, a reel, a first disc, a second disc, a drive assembly, and a fixing assembly. The cable harness is wound into the reel. When the vacuum cleaner is needed, pulling the cable harness rotates the reel, which in turn rotates the second disc. As the second disc rotates, the protrusion slides out of the groove, causing the first disc and the square rod to descend and compress the compression spring. After the cable harness is pulled to a suitable length, a slight pull causes the protrusion to rotate into the groove. The compression spring, under its elastic force, pushes the first disc to move and reset, allowing the protrusion to engage with the groove, limiting the reel's position and thus limiting the cable harness's position. The length of the pulled-out cable harness is controllable, preventing the cable harness from becoming tangled and affecting vacuuming in that area. When the cable harness needs to be wound up, the drive assembly rotates the reel to wind up the cable harness, and finally, the fixing assembly secures the cable harness plug, making it simple and convenient.

[0032] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0033] like Figure 1-7 As shown in the illustration, this application discloses a self-locking fixing device for a vacuum cleaner wiring harness, including a mounting box 10, a wire reel 20, a drive assembly 30, and a fixing assembly 50. The mounting box 10 is disposed at the bottom of the vacuum cleaner body 1. The wire reel 20 is rotatably disposed within the mounting box 10. A first fixing ring is disposed at the top of the mounting box 10, and a second fixing ring is concentrically disposed on the top surface of the wire reel 20. A bearing is disposed between the second fixing ring and the first fixing ring, with the inner ring of the bearing connected to the first fixing ring and the outer ring connected to the second fixing ring. The drive assembly 30 is disposed within the mounting box 10 and is used to drive the wire reel 20 to rotate. The fixing assembly 50 is disposed on the outer wall of the mounting box 10 near the fixing shell 40 and is used to fix the wiring harness plug. Several casters are circumferentially spaced at the bottom of the mounting box 10 to facilitate the movement of the vacuum cleaner body 1.

[0034] Specifically, a mounting post 11 is provided at the bottom of the mounting box 10. A square hole 12 is provided on the mounting post 11. A square rod 13 is vertically slidably arranged in the square hole 12. A first disc 14 is provided at the top of the square rod 13. A compression spring 15 is sleeved on the rod body of the square rod 13 located between the first disc 14 and the mounting post 11. The upper end of the compression spring 15 is connected to the bottom of the first disc 14, and the lower end is connected to the top of the mounting post 11. A second disc 21 is concentrically arranged at the bottom of the coil 20. Several protrusions 22 are spaced circumferentially on the side of the second disc 21 adjacent to the first disc 14. A groove 16 is formed on the side of the first disc 14 adjacent to the protrusions 22. Rotation of the coil 20 drives the second disc 21 to rotate, causing the protrusions 22 to slide out of the grooves 16. This causes the first disc 14 and the square rod 13 to descend, compressing the compression spring 15. The coil 20 continues to rotate. When the protrusion 22 rotates to the next groove 16, the compression spring 15 pushes the first disc 14 to move and reset under its elastic force, allowing the protrusion 22 to engage with the groove 16, thus limiting the coil 20 to several limiting positions and achieving a self-locking function. The groove 16 engages with the protrusion 22. A fixing shell 40 is provided on one side of the mounting box 10, and a circular hole 41 for the wire harness to pass through is provided on one side of the fixing shell 40. Pulling the cable harness rotates the reel 20, which in turn rotates the second disc 21. After pulling the cable harness to a suitable length, a slight pull causes the protrusion 22 to rotate into the groove 16. The compression spring 15, under its elastic force, pushes the first disc 14 to move and reset, allowing the protrusion 22 to engage with the groove 16, thus limiting the reel 20 and the cable harness. During operation, the engagement of the protrusion 22 and groove 16 can be determined by the presence of significant resistance when pulling the cable harness. The length of the pulled-out cable harness is controllable, preventing tangled cable harnesses from affecting vacuuming in that area. When it is necessary to rewind the cable harness, the drive assembly 30 drives the reel 20 to rotate, rewinding the cable harness. Finally, the fixing assembly 50 secures the cable harness plug, making the process simple and convenient.

[0035] The vertical cross-section of the protrusion 22 has a minor arc to ensure that it can slide out of the groove 16 when subjected to external force. A rotating roller 42 is vertically rotatably mounted inside the fixed housing 40 near the mounting box 10, with the wire harness surface in contact with the rotating roller 42 to prevent scratches. An electric slip ring 23 is mounted on the top of the wire reel 20. The lower end of the electric slip ring 23 is connected to the wire reel 20, and the upper end passes through the mounting box 10 and connects to the vacuum cleaner body 1. The lower end of the electric slip ring 23 is connected to the end of the wire harness via a wire, and the upper end is connected to the circuitry of the vacuum cleaner body 1 via a wire, ensuring that even when the wire reel 20 rotates, the wire harness can still stably deliver power to the vacuum cleaner body 1.

[0036] During setup, the fixing component 50 includes a sliding base 52 and an arc-shaped slide rail 51. The sliding base 52 has a slot 53 corresponding to the prong of the wire harness plug. After the wire harness is wound up, the prong of the wire harness plug is inserted into the slot 53 to fix it in place. Since the protrusion 22 needs to engage with the groove 16 after the wire harness is wound up, the position of the wire harness plug is not fixed. Therefore, the arc-shaped slide rail 51 is placed on the outer wall of the mounting box 10, and the sliding base 52 is slidably mounted on the arc-shaped slide rail 51, allowing the position of the sliding base 52 to be adjusted.

[0037] In the specific setup, a fixing tube 43 is installed at the circular hole 41 in the fixing shell 40. A sponge tube 44 is movably installed inside the fixing tube 43. The inner diameter of the sponge tube 44 is the same as the diameter of the wire harness. When the wire harness is wound up, the sponge tube 44 wipes away dust from the surface of the wire harness, ensuring its cleanliness. This also prevents a large amount of dust from entering the mounting box 10 and affecting the operation of internal components. A cap 45 with an open end is spirally installed on the fixing tube 43. A through groove 46 is opened on one side of the sponge tube 44, penetrating one side of the tube body. The cap 45 fixes the sponge tube 44. Rotating the cap 45 allows for installation or removal. The through groove 46 on the sponge tube 44 facilitates the opening of the sponge tube 44, allowing one side to pass through the wire harness before installation in the fixing tube 43. The diameter of the opening at the end of the cap 45 is larger than the inner diameter of the sponge tube 44 to prevent the edge of the opening from contacting the cap and scratching the wire harness when it is pulled.

[0038] The drive assembly 30 includes a toothed ring 31 concentrically arranged at the bottom of the coil 20. A mounting base 32 is provided inside the mounting box 10. A drive motor 33 is vertically arranged on the mounting base 32. A gear 34 is arranged on the output axis of the drive motor 33. The gear 34 meshes with the toothed ring 31. The drive motor 33 drives the gear 34 to rotate. Because the gear 34 meshes with the toothed ring 31, the rotation of the toothed ring 31 causes the coil 20 to rotate.

[0039] The working principle of the self-locking fixing device for a vacuum cleaner wiring harness in this embodiment is as follows:

[0040] When the vacuum cleaner is needed, pulling the cord harness rotates the reel 20, which in turn rotates the second disc 21. As the second disc 21 rotates, the protrusion 22 slides out of the groove 16, causing the first disc 14 and the square rod 13 to descend and compress the compression spring 15. After the cord harness is pulled to a suitable length, a slight pull causes the protrusion 22 to rotate into the groove 16. Under the elastic force, the compression spring 15 pushes the first disc 14 to move and reset, allowing the protrusion 22 to engage with the groove 16, thus limiting the reel 20 and the cord harness.

[0041] When the wire harness needs to be wound up, the drive motor 33 is started to drive the gear 34 to rotate, causing the gear ring 31 to rotate and drive the wire reel 20 to rotate. During the winding process, the sponge tube 44 wipes away dust from the surface of the wire harness. Finally, the plug of the wire harness is inserted into the slot 53 to fix the wire harness plug.

[0042] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
