When the adjustment knob 12 on the front body 3 of the spool is turned to the middle gear (the middle gear refers to the position of the adjustment knob 12 shown in FIG. 2 ), the control of the rotation of the spool by the two-way ratchet 10 is canceled, which is the same as the current ordinary cable. Disk usage is no different.

The stopper 2 is installed on the cross bar 1 . A socket 16 and a leakage protector 17 are provided on the outer side of any one of the disk bodies 3. The socket 16 is used for connecting an external power supply, and the leakage protector 17 is used to ensure the safety of the power consumption of the device. shown in Figure 3.

In this embodiment, a new type of cable reel based on a bidirectional ratchet wheel 10 is provided. The main body of the reel is composed of a reel 5 and a reel 3. The radius of the reel 3 is 33cm, the radius of the reel 5 is 20cm, and the reel body is embedded with a Two-way ratchet 10 mechanism.

The outer angle of the sixteen-pointed star is 109.5°. This design allows a gap between the ratchet wheel 10 and the pawl 6 when it rotates. The inclined ratchet tooth surface provides suitable resistance for the 90° vertex angle of the pawl when it rotates.

Referring to Figure 5, when taking up the wire, turn the adjusting knob 12 on the front disc body 3 (ie, the left disc body 3 shown in Figure 4) to the wire take-up position (that is, the position of the adjusting knob 12 shown in Figure 5). ), the adjusting knob 12 drives the movable block 7 to rotate through the connecting rod, and the movable block 7 is a notch sector block, the upper end of which is rotatably connected with the bobbin 5, and the two sides of the lower end respectively abut against the two detent claws 6 When the movable block 7 rotates, the position of the pawl 6 changes. When the adjusting knob 12 rotates to the left side as shown in FIG. 5, the spool 5 can only be rotated counterclockwise (the Clockwise and counterclockwise are based on the direction shown in Figure 5) and cannot be rotated clockwise. The pawl 6 at the corresponding position in the cavity of the bobbin 5 moves away from the ratchet 10 under the action of the movable block 7 linked by the adjustment knob 12, and holds the winding on the reverse disc body 3 (that is, the right disc body 3 shown in FIG. 4). The handle 15 rotates the main body of the spool counterclockwise, the ratchet 10 on the rotating shaft 9 does not move, the pawl 6 fixed on the spool 5 rotates with the spool 5, and the excess momentum is stored in the corresponding spring on the spool 5 in a compressed manner 8, so as to prevent the loose wire caused by excessive rotation and the unevenness of the cable 4.

Referring to Figure 6, when paying off, turn the adjusting knob 12 on the front disc body 3 (ie, the left disc body 3 shown in Figure 4) to the pay-off position (ie, the position of the adjusting knob 12 shown in Figure 6). ), the adjusting knob 12 drives the movable block 7 to rotate through the connecting rod, and the movable block 7 is a notch sector block, the upper end of which is rotatably connected with the bobbin 5, and the two sides of the lower end respectively abut against the two detent claws 6 When the movable block 7 rotates, it drives the change of the position of the pawl 6. When the adjusting knob 12 rotates to the right side as shown in Figure 5, the spool 5 can only be rotated clockwise, not counterclockwise (as shown in Figure 5). As shown in the mark of , when turning counterclockwise, the ratchet wheel 10 is restricted by the left pawl 6), which effectively prevents the spool from turning back and forth when the line is paid off. At this time, the pawl 6 at the corresponding position in the cavity of the bobbin 5 (that is, the right pawl 6 shown in FIG. 5 ) is far away from the ratchet wheel 10, and holds the reverse disc body 3 (that is, the right disc body 3 shown in FIG. 4 ). The winding handle 15 on the spool 5 rotates the spool 5 clockwise, the ratchet 10 on the rotating shaft 9 does not move, the pawl 6 fixed on the spool 5 rotates with the spool 5, and the excess momentum is stored in a compressed manner. In the corresponding spring 8 on the bobbin 5, the uniform speed of pay-off is realized, and the excessive rotation caused by the moment of inertia is effectively prevented.

When the adjustment knob 12 on the front body 3 of the spool is turned to the middle position (refer to the position of the adjustment knob 12 shown in FIG. 2 ), the control of the rotation of the spool by the two-way ratchet 10 is cancelled, which is incompatible with the use of the current ordinary cable spool. different.

In order to limit the movement trajectory of the cable 4 and reduce the risk of the cable 4 wrapping around the rotating shaft 9 , a limiter 2 fixed on the crossbar 1 is designed in this embodiment. A 12cm*6cm rectangular limiter 2 is installed on the crossbar 1, and the crossbar 1 can be used as a moving handle for the spool. The size of the stopper 2 is as follows: the outer diameter of the stopper 2 is made of a hollow steel pipe with an inner diameter of 0.6cm. The bracket and the stopper 2 are made of the same material. The rectangular stopper 2 is hollow and the hollow part is It is sufficient for an adult to pass through with one hand, so that the field operator can hold the cross bar 1 to move the wire reel, and at the same time ensure enough space for the plug 14 to pass through. The column on one side of the limiter 2 close to the bracket is flush with the front body 3 of the spool, and the column on the other side is flush with the edge of the handle. When in use, the cable plug 14 is passed through the limiter 2, and when the wire is retracted, the cable bundle track can be limited between the two reels 3, which effectively improves the problem that the cable is easily wound on the reel shaft 9 when the wire is retracted. Improve staff productivity. In addition, the limiter 2 can be used as a suspension point for the cable plug 14 when the spool is vacant, which can effectively avoid the squeezing and scratching of the cable 4 by the spring 8 clips used to fix the cable plug 14 in the past, and prevent damage to the insulation of the cable sheath. Effectively, the problem of difficult operation of fixing the cable with the spring 8 clips in field work is solved.

On the front body 3 of the spool (ie, the left body 3 shown in Figure 4 ), there is a control handle for selecting the operation of retracting and paying off the wire, and on the reverse body 3 of the spool (ie, the right body 3 shown in Figure 4 ) There are sockets 16 and leakage protectors 17. The front side of the spool is connected to the central rotating shaft 9 with a bracket, and the bottom of the spool is connected to the bracket with a support base 13 .

To sum up, this embodiment develops a new type of cable reel cable based on the bidirectional ratchet structure. The two-way ratchet structure solves the problems of excessive rotation of the spool and loose cables in the work site, and improves the controllability of the spool's rotation; the limiter installed on the crossbar of the spool improves the retractability of the spool. The bidirectional ratchet structure improves the controllability of the rotation of the spool: in this embodiment, a bidirectional ratchet structure is added to the central axis of the spool to effectively alleviate the problem of excessive rotation caused by the moment of inertia when the spool is retracting and releasing the line, and has a good effect on the rotation of the spool. Good control, reducing the workload of the staff when taking up and releasing the line. The limiter improves the retractability of the cable reel: the limiter is placed on the crossbar to limit the cable retraction trajectory within a certain range, which effectively avoids the problem that the cable is easily entangled on the rotating shaft when the cable is retracted, and improves the Staff take-up and pay-off efficiency.
