Furthermore, the elastic part and the wire wheel as a whole rotate clockwise synchronously with the knob, realizing the tightening of the wire rope. When the rotation of the knob stops and an outward pulling force is applied to the wire rope, the wire wheel will tend to rotate counterclockwise. At this time, the first linkage part will push the first elastic arm to rotate counterclockwise so that the outer diameter of the body part expands and abuts against the inner circumferential wall of the main body, thus achieving the effect of stopping rotation under the frictional force between the body part and the inner circumferential wall of the main body, and further preventing the elastic part and the wire wheel as a whole from rotating counterclockwise and causing the wire rope to loosen.

[0031] If it is necessary to loosen the wire rope, by rotating the knob in the counterclockwise direction, the second elastic arm and the second linkage part are driven to rotate counterclockwise synchronously under the abutting action of the second driving part, so that the outer diameter of the body part is reduced and separated from the inner circumferential wall of the main body. Furthermore, the elastic part and the wire wheel as a whole rotate counterclockwise synchronously with the knob, realizing the loosening of the wire rope. That is, by changing the rotation direction of the knob, the tightening and loosening of the wire rope can be achieved. The operation is simple and convenient, and the functions of preventing the wire rope from loosening, tightening the wire rope and loosening the wire rope are realized by the contact or separation between the elastic part and the inner circumferential wall of the main body, making the operation process completely silent and effectively improving the user experience. It avoids the technical problems in the prior art that the operation of the wire winder is inconvenient and the operation sound is relatively large, resulting in affecting the user experience.

[0059] As Figure 1 , Figure 2 and Figure 3 shown, an embodiment of the present application provides a silent wire winder 100, which is mainly applied to an article having the silent wire winder 100. The silent wire winder 100 includes a main body 110, a wire wheel 120 for winding wire, a knob 130 and an elastic member 140.

[0060] Wherein, the main body 110 has a receiving cavity 111 with openings at both ends. The wire wheel 120 is rotatably arranged in the receiving cavity 111 about its axis. One end of the wire wheel 120 is provided with a first linkage portion 121 and a second linkage portion 122. On one side of the knob 130 facing the main body 110, a first driving portion 131 cooperating with the first linkage portion 121 is provided, and a second driving portion 132 cooperating with the second linkage portion 122 is provided.

[0061] The elastic member 140 is arranged between the inner circumferential wall of the main body 110 and the outer circumferential wall of the wire wheel 120. The elastic member 140 includes a body portion 141, a first elastic arm 142 and a second elastic arm 143. The body portion 141 is respectively connected to the first elastic arm 142 and the second elastic arm 143. The first elastic arm 142 is located between the first driving portion 131 and the first linkage portion 121, and the second elastic arm 143 is located between the second driving portion 132 and the second linkage portion 122.

[0062] When the knob 130 is rotated clockwise, the first driving portion 131 abuts against the first elastic arm 142, the second driving portion 132 separates from the second elastic arm 143, and the body portion 141 separates from the inner circumferential wall of the main body 110. When the knob 130 is rotated counterclockwise, the first driving portion 131 separates from the first elastic arm 142, the second driving portion 132 abuts against the second elastic arm 143, and the body portion 141 separates from the inner circumferential wall of the main body 110.

[0063] In the process of using the silent wire winder 100 provided by the embodiment of the present application, when tightening the wire rope, by rotating the knob 130 in the clockwise direction, the first elastic arm 142 and the first linkage portion 121 are driven to rotate clockwise synchronously under the abutting action of the first driving portion 131, so that the outer diameter of the main body portion 141 is reduced and separated from the inner circumferential wall of the main body 110. Furthermore, the elastic member 140 and the wire wheel 120 as a whole rotate clockwise synchronously with the knob 130 to realize tightening the wire rope. When the rotation of the knob 130 stops and an outward pulling force is applied to the wire rope, the wire wheel 120 will tend to rotate counterclockwise. At this time, the first linkage portion 121 will push the first elastic arm 142 to rotate counterclockwise so that the outer diameter of the main body portion 141 expands and abuts against the inner circumferential wall of the main body 110, so as to achieve the effect of stopping rotation under the frictional force between the main body portion 141 and the inner circumferential wall of the main body 110, thereby avoiding the wire rope from loosening due to the counterclockwise rotation of the elastic member 140 and the wire wheel 120 as a whole.

[0064] If it is necessary to loosen the wire rope, by rotating the knob 130 in the counterclockwise direction, the second elastic arm and the second linkage portion 122 are driven to rotate counterclockwise synchronously under the abutting action of the second driving portion 132, so that the outer diameter of the main body portion 141 is reduced and separated from the inner circumferential wall of the main body 110. Furthermore, the elastic member 140 and the wire wheel 120 as a whole rotate counterclockwise synchronously with the knob 130 to realize loosening the wire rope. That is, by changing the rotation direction of the knob 130, the tightness of the wire rope can be realized. The operation is simple and convenient, and the functions of preventing the wire rope from loosening, tightening the wire rope and loosening the wire rope are realized by the contact or separation between the elastic member 140 and the inner circumferential wall of the main body 110, so that the operation process is completely silent, effectively improving the user experience. It avoids the technical problems in the prior art that the operation of the wire winder is inconvenient and the operation sound is relatively large, resulting in affecting the user experience.

[0065] Exemplarily, the elastic member 140 may be a cylindrical spring.

[0066] As Figures 4 to 7 shown, in an embodiment of the present application, the silent wire winder 100 further includes a transmission member 150 and a sliding member 160. The transmission member 150 is rotatably disposed about an axis at one end of the wire wheel 120 close to the knob 130. The transmission member 150 is provided with a first transmission portion 151 and a second transmission portion 152. The first transmission portion 151 is located between the first driving portion 131 and the first elastic arm 142. The second elastic arm 143 is located between the second transmission portion 152 and the second linkage portion 122. The sliding member 160 is slidably disposed on the transmission member 150. The sliding member 160 is provided with a third linkage portion 161. A third driving portion 133 cooperating with the third linkage portion 161 is provided on a side of the knob 130 facing the main body 110.

[0067] When the knob 130 is rotated clockwise, the first driving part 131 abuts against the first transmission part 151, the second transmission part 152 separates from the second elastic arm 143, the body part 141 separates from the inner circumferential wall of the main body 110, and the sliding part 160 separates from the first linkage part 121; when the knob 130 is rotated counterclockwise, the sliding part 160 abuts against the first linkage part 121 and the first transmission part 151 respectively, the second transmission part 152 abuts against the second elastic arm 143, and the body part 141 separates from the inner circumferential wall of the main body 110.

[0068] In this embodiment, during use, when tightening the wire rope, by rotating the knob 130 in the clockwise direction, the first transmission part 151, the first elastic arm 142 and the first linkage part 121 are driven to rotate synchronously in the clockwise direction under the abutting action of the first driving part 131, so that the outer diameter of the body part 141 is reduced and separated from the inner circumferential wall of the main body 110, and then the transmission part 150, the sliding part 160, the elastic part 140 and the wire wheel 120 as a whole rotate synchronously with the knob 130 in the clockwise direction to realize tightening the wire rope. When the rotation of the knob 130 stops and an outward pulling force is applied to the wire rope, the wire wheel 120 will tend to rotate counterclockwise. At this time, the first linkage part 121 will push the first elastic arm 142 to rotate counterclockwise so that the outer diameter of the body part 141 expands and abuts against the inner circumferential wall of the main body 110, so as to achieve the effect of stopping rotation under the frictional force between the body part 141 and the inner circumferential wall of the main body 110, and further prevent the transmission part 150, the sliding part 160, the elastic part 140 and the wire wheel 120 as a whole from rotating counterclockwise to cause the wire rope to loosen.

[0069] If it is necessary to loosen the wire rope, by rotating the knob 130 counterclockwise by a preset angle, the sliding part 160 slides towards the first linkage part 121 under the cooperation of the third driving part 133 and the third linkage part 161, so that the sliding part 160 abuts against the first linkage part 121 and the first transmission part 151 respectively. At this time, when an outward pulling force is applied to the wire rope, the wire wheel 120 will rotate counterclockwise and drive the transmission part 150 to rotate synchronously counterclockwise under the abutting action of the first linkage part 121, the sliding part 160 and the first transmission part 151, so that the second transmission part 152 abuts against the second elastic arm 143 and drives the second elastic arm 143 and the second linkage part 122 to rotate synchronously counterclockwise under the abutting action, so that the outer diameter of the body part 141 is reduced and separated from the inner circumferential wall of the main body 110, so that the transmission part 150, the sliding part 160, the elastic part 140 and the wire wheel 120 as a whole can rotate freely in the counterclockwise direction, and further the wire rope can be easily pulled out by the outward pulling force to loosen the wire rope.

[0070] Such as Figure 4 、 Figure 5and Figure 9 As shown in Figure 9 , in the above embodiments of the present application, a sliding groove 153 adapted to the sliding member 160 is formed on the transmission member 150, and the sliding member 160 is slidably connected to the sliding groove 153;

[0071] When the knob 130 is rotated clockwise, the sliding member 160 is located within the sliding groove 153 and separated from the first linkage portion 121; when the knob 130 is rotated counterclockwise, at least a part of the sliding member 160 extends out of the sliding groove 153 and abuts against the first linkage portion 121 and the first transmission portion 151 respectively.

[0072] In this embodiment, during use, when tightening the wire rope, by rotating the knob 130 in the clockwise direction, the sliding member 160 is caused to slide along the sliding groove 153 away from the first linkage portion 121 under the combined action of the third driving portion 133 and the third linkage portion 161, so that the sliding member 160 is located within the sliding groove 153 and separated from the first linkage portion 121. Thus, under the abutting action of the first driving portion 131, the first transmission portion 151, the first elastic arm 142 and the first linkage portion 121 are driven to rotate clockwise synchronously, reducing the outer diameter of the body portion 141 and separating it from the inner circumferential wall of the main body 110. Furthermore, the transmission member 150, the sliding member 160, the elastic member 140 and the wire wheel 120 as a whole rotate clockwise synchronously with the knob 130 to achieve tightening of the wire rope. When the rotation of the knob 130 stops and an outward pulling force is applied to the wire rope, the wire wheel 120 will tend to rotate counterclockwise. At this time, the first linkage portion 121 will push the first elastic arm 142 to rotate counterclockwise to expand the outer diameter of the body portion 141 and abut against the inner circumferential wall of the main body 110. Thus, under the frictional force between the body portion 141 and the inner circumferential wall of the main body 110, a rotation stopping effect is achieved, and further, the overall counterclockwise rotation of the transmission member 150, the sliding member 160, the elastic member 140 and the wire wheel 120 resulting in the relaxation of the wire rope is avoided.

[0073] If it is necessary to relax the wire rope, rotate the knob 130 counterclockwise by a preset angle, so that under the cooperation of the third driving part 133 and the third linkage part 161, the sliding part 160 slides along the chute 153 towards the direction close to the first linkage part 121, and the sliding part 160 at least partially extends out of the chute 153 and abuts against the first linkage part 121 and the first transmission part 151 respectively. At this time, apply an outward pulling force to the wire rope, and the wire wheel 120 will rotate counterclockwise and drive the transmission part 150 to rotate synchronously counterclockwise under the abutting action of the first linkage part 121, the sliding part 160 and the first transmission part 151, so that the second transmission part 152 abuts against the second spring arm 143 and drives the second spring arm 143 and the second linkage part 122 to rotate synchronously counterclockwise under the abutting action, thereby reducing the outer diameter of the main body part 141 and separating it from the inner circumferential wall of the main body 110, so that the transmission part 150, the sliding part 160, the elastic part 140 and the wire wheel 120 as a whole can rotate freely in the counterclockwise direction, and further the wire rope can be easily pulled out by the outward pulling force to relax the wire rope.

[0074] As Figure 4 shown, in the above-mentioned embodiment of the present application, the axis of the knob 130 coincides with the axis of the transmission part 150, and the third driving part 133 is located on the side of the chute 153 away from the first transmission part 151.

[0075] In this embodiment, by making the axis of the knob 130 coincide with the axis of the transmission part 150 and arranging the third driving part 133 on the side of the chute 153 away from the first transmission part 151, during the process of rotating the knob 130 clockwise to tighten the wire rope, the sliding part 160 can slide along the chute 153 towards the direction away from the first linkage part 121 under the cooperation of the third driving part 133 and the third linkage part 161, so that the sliding part 160 is located in the chute 153 and separated from the first linkage part 121. At the same time, during the process of rotating the knob 130 counterclockwise by a preset angle, the sliding part 160 can slide along the chute 153 towards the direction close to the first linkage part 121 under the cooperation of the third driving part 133 and the third linkage part 161, so that the sliding part 160 at least partially extends out of the chute 153 and abuts against the first linkage part 121 and the first transmission part 151 respectively.

[0076] As Figure 10 and Figure 12 shown, in the above-mentioned embodiment of the present application, a first limiting part 112 is provided on the inner circumferential wall of the main body 110, the elastic part 140 is arranged on the first limiting part 112 and is located between the inner circumferential wall of the main body 110 and the outer circumferential wall of the wire wheel 120.

[0077] In this embodiment, by providing a first limiting portion 112 on the inner circumferential wall of the main body 110 and arranging the elastic member 140 on the first limiting portion 112, the elastic member 140 is axially limited under the limiting action of the first limiting portion 112, so that the elastic member 140 is always kept between the inner circumferential wall of the main body 110 and the outer circumferential wall of the wire wheel 120, thereby ensuring the stability of the functions of preventing the wire rope from loosening, tightening the wire rope and relaxing the wire rope.

[0078] As Figure 8 and Figure 12 shown, in any of the above embodiments of the present application, a second limiting portion 134 is provided on the inner circumferential direction of one end of the knob 130 facing the main body 110, and a third limiting portion 113 cooperating with the second limiting portion 134 is provided on the outer circumferential direction of the main body 110.

[0079] In this embodiment, by providing a second limiting portion 134 on the inner circumferential direction of one end of the knob 130 facing the main body 110 and providing a third limiting portion 113 cooperating with the second limiting portion 134 on the outer circumferential direction of the main body 110, the knob 130 is limited to prevent the knob 130 from falling off the main body 110.

[0080] As Figure 11 and Figure 12 shown, in any of the above embodiments of the present application, the wire wheel 120 includes a winding shaft 123 and disc bodies 124 arranged at both ends of the winding shaft 123. The diameter of the disc body 124 is larger than the diameter of the winding shaft 123. The winding shaft 123 is respectively provided with a first wire hole 1231 and a second wire hole 1232 along a direction perpendicular to the axis of the winding shaft 123. The main body 110 is provided with a third wire hole 114 and a fourth wire hole 115. The third wire hole 114 is arranged corresponding to the first wire hole 1231, and the fourth wire hole 115 is arranged corresponding to the second wire hole 1232.

[0081] In this embodiment, one end of the wire rope can pass through the third wire hole 114 and the first wire hole 1231 in sequence and be knotted and fixed inside the wire wheel 120, and the other end of the wire rope can pass through the fourth wire hole 115 and the second wire hole 1232 in sequence and be knotted and fixed inside the wire wheel 120.

[0082] Of course, in other embodiments, the wire rope can also pass through the first wire hole 1231 and the second wire hole 1232 and be fixed inside the wire wheel 120 without knotting.

[0083] As Figure 12As shown, in any of the above embodiments of the present application, the silent wire reel 100 further includes a base 170. A first clamping portion 116 is provided at one end of the main body 110 away from the knob 130, and a second clamping portion 171 cooperating with the first clamping portion 116 is provided on one side of the base 170 facing the main body 110.

[0084] In this embodiment, by providing a first clamping portion 116 at one end of the main body 110 away from the knob 130, and providing a second clamping portion 171 cooperating with the first clamping portion 116 on one side of the base 170 facing the main body 110, the main body 110 is stably mounted on the base 170 under the clamping action of the first clamping portion 116 and the second clamping portion 171, so that the entire silent wire reel 100 can be mounted on an article through the base 170.

[0085] In another embodiment of the present application, the silent wire reel 100 (not shown in the figure) includes a main body 110, a wire wheel 120 for winding wire, a knob 130, and an elastic member 140.

[0086] Wherein, the main body 110 has a receiving cavity 111 with openings at both ends. An installation column is provided in the receiving cavity 111. The wire wheel 120 is rotatably arranged in the receiving cavity 111 around the axis and is located on the outer circumferential side of the installation column. A first linkage portion 121 and a second linkage portion 122 are provided at one end of the wire wheel 120. A first driving portion 131 cooperating with the first linkage portion 121 and a second driving portion 132 cooperating with the second linkage portion 122 are provided on one side of the knob 130 facing the main body 110. The elastic member 140 is arranged between the outer circumferential wall of the installation column and the inner circumferential wall of the wire wheel 120. The elastic member 140 includes a body portion 141, a first elastic arm 142, and a second elastic arm 143. The body portion 141 is respectively connected to the first elastic arm 142 and the second elastic arm 143. The first elastic arm 142 is located between the first driving portion 131 and the first linkage portion 121, and the second elastic arm 143 is located between the second driving portion 132 and the second linkage portion 122.

[0087] When the knob 130 is rotated clockwise, the first driving portion 131 abuts against the first elastic arm 142, the second driving portion 132 separates from the second elastic arm 143, and the body portion 141 separates from the outer circumferential wall of the installation column. When the knob 130 is rotated counterclockwise, the first driving portion 131 separates from the first elastic arm 142, the second driving portion 132 abuts against the second elastic arm 143, and the body portion 141 separates from the outer circumferential wall of the installation column.

[0088] In the process of using the silent wire winder 100 provided by the embodiments of the present application, when tightening the wire rope, for example, by rotating the knob 130 in the clockwise direction, the first elastic arm 142 and the first linkage part 121 are driven to rotate synchronously in the clockwise direction under the abutting action of the first driving part 131, so that the outer diameter of the main body part 141 expands and separates from the outer circumferential wall of the mounting column, and then the elastic part 140 and the wire wheel 120 as a whole rotate synchronously in the clockwise direction following the knob 130, realizing the tightening of the wire rope. When the rotation of the knob 130 stops and an outward pulling force is applied to the wire rope, the wire wheel 120 will tend to rotate counterclockwise. At this time, the first linkage part 121 will push the first elastic arm 142 to rotate counterclockwise so that the outer diameter of the main body part 141 shrinks and abuts against the outer circumferential wall of the mounting column, thereby achieving the effect of stopping rotation under the frictional force between the main body part 141 and the outer circumferential wall of the mounting column, and further avoiding the wire rope from loosening due to the counterclockwise rotation of the elastic part 140 and the wire wheel 120 as a whole.

[0089] If it is necessary to loosen the wire rope, by rotating the knob 130 in the counterclockwise direction, the second elastic arm and the second linkage part 122 are driven to rotate synchronously in the counterclockwise direction under the abutting action of the second driving part 132, so that the outer diameter of the main body part 141 expands and separates from the outer circumferential wall of the mounting column, and then the elastic part 140 and the wire wheel 120 as a whole rotate synchronously in the counterclockwise direction following the knob 130, realizing the loosening of the wire rope. That is, by changing the rotation direction of the knob 130, the tightening and loosening of the wire rope can be achieved. The operation is simple and convenient, and the functions of preventing the wire rope from loosening, tightening the wire rope and loosening the wire rope are realized by the contact or separation between the elastic part 140 and the outer circumferential wall of the mounting column, making the operation process completely silent and effectively improving the user experience. It avoids the technical problems in the prior art that the wire winder is inconvenient to operate and has a relatively loud operation sound, which affects the user experience.
