Description

Technical Field

[0001] The utility model relates to a wire winder structure for a curtain, in particular to a wire winder structure for a curtain that can prevent the winding wires from being interfered with and entangled with each other. Background Art

[0002] As shown in the figure Figures 12 to 15 is a conventional rope winder (90). Two wire winding shafts (91) are pivotally provided on the rope winder (90). Each of the wire winding shafts (91) is wound with a winding wire (92) that passes through the bottom of the rope winder (90). When the wire winding shaft (91) rotates, if the winding wire (92) is affected by an external force, it may be stacked on the rest of the winding wire (92), causing the winding wire (92) to become entangled on the surface of the wire winding shaft (91). As a result, the winding wire (92) cannot be evenly wound around the wire winding shaft (91) in circles, thus affecting the height of the curtain connected to the winding wire (92). Usually, more than two such rope winders (90) are installed. Therefore, during the same rotation stroke, the winding wire (92) of one side of the rope winder (90) becomes entangled on the surface of the wire winding shaft (91), resulting in inconsistent heights on both sides of the curtain. In this way, it is necessary to pull down the curtain and rewind the winding wire (92), which is inconvenient and unsatisfactory in use and still needs to be improved.

[0003] Therefore, in view of this, the inventor of the present utility model came up with the idea of creation, and then designed it based on years of experience. After extensive discussions, sample tests were conducted, and multiple corrections and improvements were made, and then the present utility model was introduced. Summary of the Utility Model

[0004] The technical problem to be solved by the present utility model is to provide a wire winder structure for a curtain to address the above-mentioned deficiencies in the prior art.

[0005] Technical features for solving the problem:

[0006] The utility model provides a wire winder structure for a curtain, which includes at least two wire winders symmetrically arranged above a curtain. Among them, each wire winder has a base. In the center of the left side of the base, two base holes are pivotally arranged side by side. Above each base hole on the base, a first guide shaft is pivotally arranged. At the front and rear of the right side of the bottom of the base, a second guide shaft is pivotally arranged respectively. Two winding shafts are pivotally arranged symmetrically in the front and rear of the base above the first guide shaft and the second guide shaft. A rope body passes through each base hole, and one end of the rope body is fixed to the top and bottom of the curtain respectively. The rope body is attached to the first guide shaft and the second guide shaft and the other end is arranged on the winding shaft. After the winding shaft rotates, the rope body can be wound around the winding shaft to retract the rope body, or after pulling down the rope body, the winding shaft can be rotated in the reverse direction to pull out the rope body wound on it, so as to raise or lower the top or bottom of the curtain to unfold or retract the curtain.

[0007] Further, a winding rod is arranged through each winding shaft, and the winding rod rotates through a winding chain, so that the winding rod and the winding shaft rotate synchronously coaxially.

[0008] Preferably, a limiting ring is slidably arranged on the winding shaft, and the rope body is arranged on the winding shaft by being fixed to the limiting ring, so as to limit the rope body wound on the winding shaft to be neatly wound on the winding shaft.

[0009] The main purpose of the utility model is that the two second guide shafts are located at the front and rear of the right side of the bottom of the base, so that the two rope bodies are respectively forward and backward between the first guide shaft and the second guide shaft and do not contact each other to avoid mutual interference. After the rope body is attached to the second guide shaft and then arranged on the winding shaft, when the rope body accidentally gets off the first guide shaft due to external interference, the rope body still abuts against the second guide shaft to bear the friction force, so that the section of the rope body getting off the first guide shaft is controlled between the first guide shaft and the second guide shaft, avoiding the rope body from further rising and overlapping and entangling with each other on the winding shaft, and avoiding the height of the top or bottom of the curtain from changing due to the entanglement of the rope body, resulting in different heights and inclinations on both sides.

[0039] To further understand and recognize the purpose, features and functions of the present utility model, the following examples are hereby listed in conjunction with [Brief description of the drawings] and described in detail as follows:

[0040] First, please start from Figures 1 to 8 As shown, the present utility model provides a structure of a curtain winder, which includes at least two winders (10). The winders (10) are symmetrically arranged above a curtain (20). Among them, the winder (10) has a base (11). Two base holes (111) are pivotally arranged side by side at the center of the left side of the base (11). Above each of the base holes (111) of the base (11), a first guide shaft (12) is pivotally arranged. At the front and back of the right side of the bottom of the base (11), a second guide shaft (13) is pivotally arranged respectively. Two winding shafts (14) are pivotally arranged symmetrically in the front and back of the base (11) above the first guide shaft (12) and the second guide shaft (13). A rope body (30) passes through each of the base holes (111), and one end of it is respectively fixed to the top and bottom of the curtain (20). The rope body (30) is attached to the first guide shaft (12) and the second guide shaft (13), and the other end is arranged on the winding shaft (14). From Figures 9 to 11 As shown, after the winding shaft (14) rotates, the rope body (30) can be wound around the winding shaft (14) to retract the rope body (30), or after pulling down the rope body (30), the winding shaft (14) can be rotated in the reverse direction to pull out the rope body (30) wound on it, so that the top or bottom of the curtain (20) rises or falls to unfold or retract the curtain (20).

[0041] With the above structure, the two second guide shafts (13) are located at the front and back on the right side of the bottom of the base (11), such that the two rope bodies (30) are respectively forward and backward between the first guide shaft (12) and the second guide shaft (13) without contacting each other to avoid mutual interference. After the rope body (30) is attached to the second guide shaft (13), it is arranged on the winding shaft (14). When the rope body (30) accidentally disengages upward from the first guide shaft (12) due to external interference, the rope body (30) still adheres to the second guide shaft (13) to bear the frictional force, so as to control the section of the rope body (30) disengaging from the first guide shaft (12) between the first guide shaft (12) and the second guide shaft (13), avoiding the rope body (30) from further moving upward and overlapping and entangling with each other on the winding shaft (14), and avoiding the entanglement of the rope body (30) causing changes in the height of the top or bottom of the curtain (20) and resulting in different heights and inclinations on both sides.

[0042] As shown by Figures 9 to 11 the present utility model provides a winding structure for a curtain, wherein each of the winding shafts (14) is provided with a winding rod (141) passing through it, and the winding rod (141) rotates through a winding chain (40), so that the winding rod (141) and the winding shaft (14) rotate synchronously coaxially.

[0043] The present utility model provides a winding structure for a curtain, wherein a limiting ring (142) is slidably arranged on the winding shaft (14), and the rope body (30) is arranged on the winding shaft (14) by being fixed to the limiting ring (142) to limit the rope body (30) wound around the winding shaft (14) to be neatly wound around the winding shaft (14). As shown by Figures 9 to 11 when the number of turns of the rope body (30) wound around the winding shaft (14) increases, the limiting ring (142) can be gradually pushed, and conversely, when the rope body (30) is pulled out, the limiting ring (142) can be gradually pulled back, so that the rope body (30) is neatly wound around the winding shaft (14).

[0044] As shown by Figures 1 to 3 the present utility model provides a winding structure for a curtain, wherein two top covers (15) are arranged on the top of the base (11) to limit the upper part of the winding shaft (14).

[0045] The above content is only a preferred embodiment of the present utility model, and the scope of implementation of the present utility model cannot be limited thereby; that is, all equivalent changes and modifications made according to the scope of the patent application of the present utility model should still fall within the scope covered by the patent of the present utility model.
