Description

Technical Field

[0001] This utility model belongs to the technical field of rope winding equipment, specifically relating to a rope winding anti-tangling structure for a rope winding device. Background Technology

[0002] Existing electric curtains control the automatic raising and lowering of the curtain body by using a rope reel to control the automatic winding and unwinding of the rope. However, during the winding or unwinding process, the existing rope reel is prone to folding and other phenomena, which can cause the rope to jam, affecting the normal operation of the electric curtain and impacting the user experience. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a rope winding anti-tangling structure for a rope winder.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A rope winding anti-tangling structure for a rope winder includes a rope winding wheel with a rope body wound around its outer periphery. One end of the rope body is a fixed end and the other end is a free end. The fixed end of the rope body is fixed to one end of the rope winding wheel, and the other end of the rope winding wheel is the rope winding inlet end. The free end of the rope body is circumferentially wound around the rope winding wheel from the rope winding inlet end. A rope winding limiting cover is provided on one side of the rope winding wheel, forming a rope winding gap between the rope winding wheel and the rope winding limiting cover, with the rope winding limiting cover close to the rope. The inner side of one end of the winding end is provided with a winding guide structure. The winding rope body can be fixedly mounted on the winding wheel body through the fixed end, which allows the free end to move and wind around the winding wheel body. The winding limit cover allows the winding rope body to move and be positioned within the winding gap during the winding state, which can effectively prevent the winding rope body from overlapping or getting stuck, ensuring the smoothness of the winding rope body during release and winding. The winding guide structure can guide and limit the winding rope body, preventing the winding rope body from slipping out of the winding wheel body and ensuring that the winding rope body is oriented towards the fixed end during winding, thus ensuring the winding effect of the winding rope body on the winding wheel body.

[0005] In the above-mentioned anti-tangle structure of a rope reel, the rope reel body is cylindrical, and the rope limiting cover is an arc-shaped plate that matches the outer side of the rope reel body. The rope limiting cover extends from one end of the rope reel body to the other end. The arc-shaped plate structure allows the rope limiting cover to match the curvature of one side of the rope reel body, thereby improving the limiting and guiding effect on the rope reel body.

[0006] In the above-mentioned anti-tangling structure of a rope winder, the rope winding gap is set with equal width and the width of the rope winding gap is not less than the diameter of the rope body. The size of the rope winding gap is suitable for the diameter of a single rope body, which can prevent the rope body from overlapping, ensure the winding effect of the rope body, and improve the smoothness of rope unwinding.

[0007] In the above-mentioned anti-tangling structure of a rope winder, the winding guide structure includes a winding guide rib disposed on the inner side of the end of the rope winding limit cover near the winding end. The winding guide rib has a winding guide surface on the side facing the fixed end of the rope body. The winding guide rib abuts against the side of the rope winding wheel. The rope body is wound toward the fixed end through the winding guide rib and the winding guide surface, thereby increasing the winding density of the rope body on the rope winding wheel and reducing the winding range.

[0008] In the above-mentioned anti-tangle structure of a rope winder, the winding guide rib is arc-shaped and the winding guide surface is arc-shaped. The open end of the winding guide rib faces the end of the rope winding limit cover near the rope winding end, and both ends of the winding guide rib extend to both sides of the end of the rope winding limit cover near the rope winding end. This can improve the guiding and limiting effect of the winding guide rib on the rope body, and the arc shape can increase the contact area between it and the rope winding wheel, ensuring the guiding and limiting effect.

[0009] In the above-mentioned anti-tangle structure of a rope winder, the winding guide rib is integrally formed on the rope winding limit cover, which can improve the overall structural strength of the winding guide rib, increase its service life, and ensure the limiting and guiding effect on the rope body.

[0010] In the above-mentioned anti-tangle structure of a rope winder, the rope winding limit cover is provided with a number of strip grooves that extend axially through the rope winding limit cover. The strip grooves are connected to the rope winding gap, and the rope body in the rope winding gap can be cooled through the strip grooves, effectively preventing the rope body from overheating during the rope winding and unwinding process, which would affect its service life.

[0011] In the above-mentioned anti-tangle structure of a rope winder, the outer side of the rope winding limit cover has several limit cover locking seats. The limit cover locking seats are vertically arranged on both sides of the rope winding limit cover, and the limit cover locking seats and the rope winding limit cover are integrated into one structure. The integrated structure can improve the structural strength between the limit cover locking seats and the rope winding limit cover, and can also improve the service life of the limit cover locking seats.

[0012] In the above-mentioned anti-tangling structure for a rope winder, one side of the limiting cover locking seat is connected to the rope winder via a locking assembly. The locking assembly includes an upper locking block and a lower locking block, with a locking space between the upper and lower locking blocks. The rope winder is positioned within the locking space and is locked to both the upper and lower locking blocks. The limiting cover locking seat is located inside the rope winder, and the inner shell of the rope winder is placed within the locking space. The upper and lower locking blocks radially limit the inner shell of the rope winder, ensuring the connection stability between the limiting cover locking seat and the rope winder.

[0013] In the above-mentioned anti-tangle structure of a rope winder, the two ends of the rope winding limit cover have arc-shaped folded edges that extend outwards. The arc-shaped folded edges abut against the rope winder housing and can protect the rope winding wheel and the rope winding body through the arc-shaped folded edges, effectively preventing foreign objects from entering the rope winding gap and ensuring the smooth operation of the rope winding body.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] 1. The rope winding limit cover and the rope winding gap can limit the height of the rope winding body on the rope winding wheel, effectively preventing the rope winding body from overlapping and jamming, and ensuring the smoothness of the rope winding body during operation.

[0016] 2. The winding guide structure enables the rope to be wound toward the fixed end, ensuring the winding effect and limiting the rope to prevent it from falling off the winding wheel.

[0017] 3. The snap-fit ​​assembly ensures the installation stability of the rope winding limit cover and guarantees the limiting effect on the rope winding body. Attached Figure Description

[0022] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0023] like Figure 1 , Figure 2 , Figure 3 As shown, the anti-tangling structure of this rope winder includes a rope winder body 1 with a rope body 2 wound around its outer periphery. One end of the rope body 2 is a fixed end 21 and the other end is a free end 22. The fixed end 21 of the rope body 2 is fixed to one end of the rope winder body 1, and the other end of the rope winder body 1 is a rope winding inlet end 11. The free end 22 of the rope body 2 is wound around the rope winder body 1 from the rope winding inlet end 11. A rope winding limiting cover 3 is provided on one side of the rope winder body 1, and a rope winding gap 4 is formed between the rope winder body 1 and the rope winding limiting cover 3. A winding guide structure 5 is provided on the inner side of the end of the rope winding limiting cover 3 near the rope winding inlet end 11. The rope body 2 is fixedly mounted on the winding wheel 1 at one end via the fixed end 21, allowing the free end 22 to move around the winding wheel 1. The rope limiting cover 3 allows the rope body 2 to move within the rope gap 4 during winding, effectively preventing the rope body 2 from overlapping or getting stuck, ensuring the smoothness of rope release and winding. The winding guide structure 5 guides and limits the rope body 2, preventing it from slipping out of the winding wheel 1 and ensuring that the rope body 2 winds towards the fixed end 21, thus guaranteeing the winding effect of the rope body 2 on the winding wheel 1.

[0024] Specifically, the rope winding wheel 1 is cylindrical, and the rope winding limit cover 3 is an arc-shaped plate that matches the outer side of the rope winding wheel 1. The rope winding limit cover 3 extends from one end of the rope winding wheel 1 to the other end. The arc-shaped plate structure can make the rope winding limit cover 3 match the curvature of one side of the rope winding wheel 1, which can improve the limiting and guiding effect on the rope winding body 2 on the rope winding wheel 1.

[0025] Among them, the rope gap 4 is set with equal width and the width of the rope gap 4 is not less than the diameter of the rope body 2. The size of the rope gap 4 is suitable for the diameter of a single rope body 2, which can prevent the rope body 2 from overlapping, ensure the winding effect of the rope body 2, and improve the smoothness of releasing the rope body 2.

[0026] like Figure 1 , Figure 3 As shown, the winding guide structure 5 includes a winding guide rib 51 disposed on the inner side of one end of the winding limit cover 3 near the winding end 11. The winding guide rib 51 has a winding guide surface 52 on the side facing the fixed end 21 of the winding rope body 2. The winding guide rib 51 abuts against the side of the winding wheel body 1. The winding rope body 2 is wound toward the fixed end 21 through the winding guide rib 51 and the winding guide surface 52, thereby increasing the winding density of the winding rope body 2 on the winding wheel body 1 and reducing the winding range.

[0027] Furthermore, the winding guide rib 51 is arc-shaped and the winding guide surface 52 is arc-shaped. The open end of the winding guide rib 51 faces the end of the rope winding limit cover 3 near the rope winding end 11, and both ends of the winding guide rib 51 extend to both sides of the end of the rope winding limit cover 3 near the rope winding end 11. This can improve the guiding and limiting effect of the winding guide rib 51 on the rope body 2, and the arc shape can increase the contact area between it and the rope winding wheel 1, ensuring the guiding and limiting effect.

[0028] Among them, the winding guide rib 51 is integrally formed on the rope limiting cover 3, which can improve the overall structural strength of the winding guide rib 51, increase its service life, and ensure the limiting and guiding effect on the rope body 2.

[0029] Combination Figure 1 , Figure 2 , Figure 3 As shown, the rope winding limit cover 3 is provided with a number of strip grooves 31 that pass through the rope winding limit cover 3 and extend axially. The strip grooves 31 are connected to the rope winding gap 4, and the rope winding body 2 in the rope winding gap 4 can be cooled through the strip grooves 31, which effectively prevents the rope winding body 2 from being too hot during the rope winding and unwinding process, thus affecting its service life.

[0030] Among them, the outer side of the rope winding limit cover 3 has several limit cover locking seats 32, which are vertically arranged on both sides of the rope winding limit cover 3. The limit cover locking seats 32 and the rope winding limit cover 3 are connected as an integral structure. The integral structure can improve the structural strength between the limit cover locking seats 32 and the rope winding limit cover 3, and can also improve the service life of the limit cover locking seats 32.

[0031] Specifically, the limiting cover latching seat 32 is connected to the rope winder via a latching assembly 6. The latching assembly 6 includes an upper latching block 61 and a lower latching block 62, with a latching space 63 between the upper latching block 61 and the lower latching block 62. The rope winder is positioned within the latching space 63 and is latched to both the upper latching block 61 and the lower latching block 62. The limiting cover latching seat 32 is positioned inside the rope winder, and the inner shell of the rope winder is placed within the latching space 63. The upper latching block 61 and the lower latching block 62 provide radial limiting for the inner shell of the rope winder, ensuring the stability of the connection between the limiting cover latching seat 32 and the rope winder.

[0032] Combination Figure 1 , Figure 3 As shown, the rope winding limit cover 3 has arc-shaped folded edges 33 extending outward at both ends. The arc-shaped folded edges 33 abut against the rope winding device housing and can protect the rope winding wheel 1 and the rope winding body 2 through the arc-shaped folded edges 33, effectively preventing debris from entering the rope winding gap 4 and ensuring the smooth operation of the rope winding body 4.

[0033] The principle of this embodiment is as follows: the rope body 2 is connected to the rope wheel 1 through the fixed end 21 and the free end 22 can wind or unwind the rope as the rope wheel 1 rotates. The rope limiting cover 3 and the rope gap 4 can limit the rope body 2 during the winding and unwinding process, which can prevent the rope body 2 from folding or other phenomena, and ensure the smooth operation of the rope body 2. In addition, the winding guide structure 5 can limit and guide the rope body 2, ensuring that the rope body 2 can wind towards the fixed end 21 and ensure the winding effect.

[0034] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0035] Although this document frequently uses terms such as rope winding wheel 1, rope winding end 11, rope winding body 2, fixed end 21, free end 22, rope winding limit cover 3, strip groove 31, limit cover locking seat 32, arc-shaped folded edge 33, rope winding gap 4, winding guide structure 5, winding guide rib 51, winding guide surface 52, locking assembly 6, upper locking block 61, lower locking block 62, and locking space 63, the possibility of using other terms is not excluded. The use of these terms is merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any kind of additional limitation would contradict the spirit of this utility model.
