DETAILED DESCRIPTION

[0021] As Figure 1 shown, the utility model is a swing type positioning telescopic data line winding device.

[0022] As Figure 2 , 5 and 6 shown, a swing type positioning telescopic data line winding device, including shell 1, control mechanism 2, rotating disc 3, conductive mechanism 4, spring 5 and data line 6, rotating disc 3 rotatably installed in the middle part of shell 1, provides power for the take-up of data line, the conductive mechanism 4 is installed at the top of rotating disc 3, to connect the input dynamic end and output static end of data line, the control mechanism 2 is installed at the bottom of upper shell, to position the position of rotating disc rotation, the spring 5 is installed at the bottom of rotating disc, to provide power for take-up.

[0023] As Figure 1 and 2 shown, the shell 1 includes upper shell 11 and lower shell 12, the upper shell 11 is buckled with lower shell 12, forms a space for rotating disc 3 rotation, the inside center of lower shell 12 is equipped with first rotating shaft 121, and the rotating disc 3 is installed on the rotating shaft.

[0024] The bottom center of upper shell 11 is equipped with contact plate installation site 113, and the second rotating shaft 111, third rotating shaft 112 and reset spring site 114 are arranged on the periphery side of contact plate installation site 113, and the control mechanism 2 is installed on the second rotating shaft 111, third rotating shaft 112 and reset spring site 114.

[0025] As Figure 2 , 3As shown in Figure 4, the turntable 3 has a first shaft hole 34 at its center, a positioning plate 35 at its top, the positioning plate 35 being circular with four positioning holes 33 evenly distributed on its circumference, and a mounting chamber for a connecting plate 43 and a contact head 42 in its center; the turntable 3 has a take-up reel 32 at its bottom, and a spring chamber 31 in its center, the take-up reel 32 being used to wind and store the data cable 6, and the spring chamber 31 being used to install the spring 5. The turntable 3 is mounted on the first rotating shaft 121 through the first shaft hole.

[0026] like Figure 2 , 5 As shown in Figure 6, the control mechanism 2 includes a reset spring 21, a swing-type positioning plate 22, and a positioning cam 23. The reset spring 21 is mounted on the reset spring position 114, the swing-type positioning plate 22 is mounted on the second rotating shaft 111, and the positioning cam 23 is mounted on the third rotating shaft 112.

[0027] like Figure 2 , 3 As shown in Figure 6, the conductive mechanism 4 includes a contact plate 41, a contact head 42, and a connecting plate 43. The contact plate 41 is used to connect the inner end of the data cable, the connecting plate 43 is used to connect the outer end of the data cable, and the contact head 42 is connected to the connecting plate 43 and rotatably contacts the contact plate 41.

[0028] like Figure 2 and 3 As shown, the inner end of the spring 5 is fixed to the first rotating shaft 121, and the outer end of the spring 5 is fixed to the inner side of the take-up reel 32. When the data cable 6 is pulled out, the spring 5 is tightened, generating a reset potential energy. When the tension of the data cable 6 is released, driven by the reset potential energy, the spring 5 automatically resets, causing the turntable 3 to rotate in the opposite direction, and the data cable 6 is wound around the outside of the take-up reel 32 and thus retrieved.

[0029] like Figure 5 , 6 As shown in Figure 8, the positioning cam 23 has a third shaft hole 232 in the middle and a locking cam 231 on the bottom surface. The locking cam 231 has a first tooth 2311 and a second tooth 2312 at both ends of its major diameter. The third shaft hole 232 is used to cooperate with the third rotating shaft 112. The positioning cam 23 is rotatably mounted on the third rotating shaft 112.

[0030] like Figure 7As shown, the swing positioning piece 22 includes a first pawl 221, a second pawl 222, a third pawl 223, a second shaft hole 224 and a reset surface 225. The first pawl 221 is arranged on the side of the swing positioning piece 22 close to the positioning disc 35, the reset surface 225 is arranged on the side away from the positioning disc 35, and the second pawl 222 and the third pawl 223 are arranged on the top of the swing positioning piece 22 and distributed on the left and right sides of the locking cam 231. The first pawl 221 is on the outside of the positioning disc 35 and slides along the outside of the positioning disc 35 with the rotation of the rotating disc 3. When the rotating disc 3 rotates by one positioning port 33, the first pawl 221 falls into the positioning port 33 and then slides out of the positioning port 33, with a click sound. The directions of the second pawl 222 and the third pawl 223 are opposite, and the second pawl 222 and the third pawl 223 are on the first lobe 2311 and the second lobe 2312 from the left side of the first lobe and the right side of the second lobe respectively, providing a rotating force to the cam 23 from two opposite directions to rotate the positioning cam 23 on the third rotating shaft 112.

[0031] As shown in Figure 6 The reset surface 225 is close to the inside of the reset spring 21. When the rotating disc 3 does not rotate, the swing positioning piece 22 always keeps in the normal position. When the rotating disc 3 rotates, the swing positioning piece 22 deflects under the push of the first pawl 221 in the positioning port 33. When the rotating disc 3 stops rotating, the swing positioning piece 22 returns to the normal position under the action of the reset spring 21.

[0032] As shown in Figure 3 , 5 When the data line 6 is pulled out, the rotating disc 3 rotates clockwise, the positioning port 33 rotates clockwise with the rotating disc 3, the first pawl 221 swings to the left under the push of the positioning port 33, the third pawl 223 pushes the locking cam 231 to rotate clockwise from the right inner end of the locking cam 231 at this time, the first pawl 221 is out of the positioning port 33 when it swings to the left to a certain angle, the swing positioning piece 22 swings to the right rapidly under the action of the reset spring 21 because there is no pushing force at this time, the second pawl 222 pushes the locking cam 231 to rotate clockwise from the left outer end of the locking cam 231 at this time, the pulling force of the data line 6 is cancelled when the second pawl 222 engages with the first lobe 2311 or the second lobe 2312, the rotating disc 3 rotates clockwise under the action of the spring 5, the first pawl 221 swings to the right under the push of the positioning port 33, and because the sum of the distances from the meshing points of the second pawl 222 and the second lobe 2312 to the second rotating shaft 111 and the third rotating shaft 112 is greater than the distance between the second rotating shaft 111 and the third rotating shaft 112, the third pawl 223 pushes the locking cam 231 to rotate counterclockwise from the left inner end of the locking cam 231 at this time.

[0033] The swing positioning sheet 22 cannot continue to swing to the right, and the length of the pulled-out data line 6 is locked. When the data line 6 is to be recovered, a little data line 6 is pulled out, the swing positioning sheet 22 which cannot swing to the right swings to the left, at this time the second pawl 222 is no longer engaged with the first protrusion 2311, the third pawl 223 pushes the locking cam 231 from the left outer end of the locking cam 231 to rotate the locking cam 231 clockwise, when the pulling of the data line 6 is stopped, the rotating disc 3 rotates clockwise under the action of the spring 5, the swing positioning sheet 22 is driven to swing to the left by the first pawl 221, and the second pawl 222 misses the first protrusion 2311 when swinging to the left, so that the engagement state is not formed, and the data line 6 is smoothly recovered under the action of the spring 5.

[0034] In order to further shorten the unit length of the single-locked data line and make the length of the pulled-out data line more accurate each time, the positioning port 33 is provided with four, which are uniformly distributed on the circumference of the positioning disc 35, and the positioning disc 35 will have four positioning opportunities every time it rotates one circle.

[0035] In use, when the length of the pulled-out data line is not enough and part of the data line needs to be pulled out again, a certain length of the data line 6 is pulled out and then stopped, and the rotating disc 3 rotates clockwise under the action of the spring 5, driving the swing positioning sheet 22 to swing to the left, when the second pawl 222 approaches the locking cam 231, if it does not collide with the first protrusion 2311 and the second protrusion 2312 of the locking cam 231, the second pawl 222 is attached to the locking cam 231, and the second pawl 222 has two engagement opportunities with the first protrusion 2311 or the second protrusion 2312 every time the locking cam 231 rotates one circle.

[0036] Since the positioning disc 35 rotates around the first rotating shaft 121 and the swing positioning sheet 22 swings left and right around the second rotating shaft 111, the sum of the radius of the positioning disc 35 and the maximum radius of the swing positioning sheet 22 is greater than the shaft distance between the first rotating shaft 121 and the second rotating shaft 111, so when the first pawl 221 falls into the positioning port 33, the swing positioning sheet 22 can only swing from one direction to another direction, therefore the positioning port 33 is the switching point of the swing positioning sheet 22 to change the swing direction, and the positioning disc 35 rotates one circle every time, and the first pawl 221 passes through four positioning ports 33.

[0037] As shown in Figure 9 The axis of the swing positioning sheet 22 is point A, the axis of the cam 23 is point B, and the engagement points of the second pawl 222 and the first protrusion 2311 or the second protrusion 2312 are point C or point D. Since the distance from point A to point D plus the distance from point D to point B is greater than the distance between points A and B, the swing positioning sheet 22 will not swing to the right under the action of the spring 5, resulting in the stop of the rotating disc 3, and the length of the data line 6 is locked.

[0038] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Any equivalent changes made in accordance with the structure, shape, and principle of the present application shall be encompassed within the protection scope of the present application.
