DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] In one embodiment, please refer to the attached manual. Figure 1-5 As shown, a line-releasing device described in the utility model comprises a bobbin 1, a bracket 2 is arranged on the bobbin 1, a shield 11 is arranged at one end of the bobbin 1, a motor 12 is arranged on the shield 11, a sleeve 13 is arranged on the output end of the motor 12, a plurality of fixing plates 15 are arranged on the sleeve 13, a rotating plate 14 corresponding to the fixing plate 15 is arranged on one side of the fixing plate 15, the rotating plate 14 is arranged on the shield 11, and the rotating plate 14 rotates unidirectionally around the shield 11; the shield 11 is rotatably connected with the rotating rod through a support; a plurality of pushing mechanisms 3 are arranged on the sleeve 13, the pushing mechanism 3 is used to push the bobbin 1 to rotate, a locking mechanism 4 installed on the shield 11 is arranged above the pushing mechanism 3, and the locking mechanism 4 is used to limit the rotation of the bobbin 1.

[0021] The locking mechanism 4 is provided to prevent the bobbin 1 from rotating when it is not necessary to release the wire, and to limit the rotation of the bobbin 1, thereby ensuring that the wires are not in a mess during the release process; and there is no need to manually stop and release the bobbin 1 for releasing the wire, thereby freeing up manpower. At the same time, the device can achieve locking without the need for the motor 12 to self-lock, thereby reducing the load of the motor 12 and increasing the service life of the motor 12. The pushing mechanism 3 is provided to push the bobbin 1 to rotate, so that when it is necessary to release the wire, the motor 12 drives the pushing mechanism 3 to release the wire, thereby improving the efficiency of releasing the wire. The cooperation of the rotating piece 14 and the fixing piece 15 is provided, so that when the bobbin 1 is releasing the wire, the motor 12 can drive the bobbin 1 to rotate and release the wire, and when winding the wire, only the bobbin 1 is allowed to rotate and wind the wire, thereby avoiding collision between the pushing mechanism 3 and the locking mechanism 4.

[0022] The pushing mechanism 3 includes a plurality of push rods 34 arranged on the outer wall of the sleeve 13, a push plate 32 is movably arranged on the push rod 34, a stopper 31 is arranged on one side of the push plate 32, the stopper 31 is arranged on the end of the bobbin 1, a through slot 33 is opened on the side wall of the push plate 32, the push rod 34 passes through the through slot 33 and extends to the inside of the push plate 32; a first baffle 35 is sleeved on the end of the push rod 34, a push rod 36 is arranged on one side of the first baffle 35, a first elastic member 37 is sleeved on the push rod 36, the first elastic member 37 is arranged inside the push plate 32, and the first elastic member 37 is used to push the push rod 34 to reset.

[0023] The pushing mechanism 3 further includes a support rod 38 disposed on the first baffle 35 , and a first squeezing block 39 for squeezing the locking mechanism 4 to unlock is disposed at the end of the support rod 38 .

[0024] The push rod 34 moves inside the push plate 32 , and the push rod 34 drives the support rod 38 to move synchronously.

[0025] When it is necessary to push the wire drum 1 to release the wire, the motor 12 is started. The motor 12 drives the push rod 34 to rotate through the shaft sleeve 13, and the push rod 34 drives the first baffle plate 35 to rotate, and the first baffle plate 35 squeezes the first elastic member 37, and the first elastic member 37 is compressed until the push rod 36 abuts against the inner wall of the push plate 32, and the push plate 32 is driven to rotate. After the push plate 32 rotates to one side of the stop block 31, the push plate 32 drives the stop block 31 to rotate synchronously, and then the stop block 31 drives the wire drum 1 to rotate, and the wire wound on the wire drum 1 is released; during the movement of the push rod 34, the push rod 34 will first drive the support rod 38 and the first extrusion block 39 to move synchronously, and the first extrusion block 39 will first squeeze on the locking mechanism 4. When the locking mechanism 4 is unlocked, the first elastic member 37 is just compressed to the maximum value, and at the same time, the push rod 36 just abuts on the inner wall of the push plate 32, so that the wire drum 1 and the shield 11 can rotate relative to each other.

[0026] The locking mechanism 4 includes a locking hole 16 arranged on the shield 11, a support plate 41 is arranged on the shield 11, a storage groove is arranged inside the support plate 41, an opening groove 42 is opened on one side of the storage groove, a second baffle 47 is arranged inside the storage groove, a locking rod 43 is arranged below the second baffle 47, a second elastic member 46 is sleeved on the locking rod 43, the top of the locking rod 43 is connected to the second baffle 47, and the locking rod 43 enters the interior of the locking groove to achieve locking.

[0027] The locking mechanism 4 further includes a connecting rod 44 disposed on the locking rod 43 . The connecting rod 44 slides inside the opening slot 42 . A second extrusion block 45 is disposed at the end of the connecting rod 44 . The first extrusion block 39 abuts against the second extrusion block 45 .

[0028] When the first extrusion block 39 just contacts the second extrusion block 45, since the contact surfaces of the first extrusion block 39 and the second extrusion block 45 are both inclined surfaces, the second extrusion block 45 is pushed upward by the first extrusion block 39. When the second extrusion block 45 is pushed upward, the second extrusion block 45 drives the locking rod 43 to move upward, and the locking rod 43 will move out from the inside of the locking hole 16, and the locking rod 43 will not limit the block 31 on one side. When the push plate 32 continues to move, the push plate 32 drives the wire drum 1 to rotate. When the wire drum 1 rotates without being pushed by the push plate 32, the locking rod 43 will slide on the outer wall of the shield 11. Since a plurality of locking holes 16 are provided on the outer wall of the shield 11, the locking rod 43 will enter above the corresponding locking hole 16. At this time, the second elastic member 46 pushes the locking rod 43 into the inside of the locking groove to achieve locking, thereby preventing the wire from rotating uncontrollably.
