Actuating mechanism 4 includes damping spring 41 and spring mount 42, damping spring 41 cup joints on right pivot 221, just damping spring 41's left end is fixed in reel 1, damping spring 41's right-hand member passes through spring mount 42 connects on right side board 22, works as through rotating reel 1 makes damping spring 41 is in after the tightening state, loosens reel 1 under damping spring 41's the restoring force effect, can drive reel 1 rotates to opposite direction. The locking mechanism 5 comprises a clamping block 51 which is arranged on the left side plate 21 and is provided with a U-shaped clamping groove 52, and a tightening mechanism which is arranged on the clamping block 51 and is used for controlling the tightness degree of the U-shaped clamping groove 52, wherein the U-shaped clamping groove 52 is clamped on the left rotating shaft 221; after the U-shaped clamping groove 52 clamps the left rotating shaft 221, the rotation of the left rotating shaft 221 is limited, and the winding drum 1 is locked; when the U-shaped clamping groove 52 becomes loose, it cannot restrict the rotation of the left rotating shaft 221, and thus the reel 1 can be rotated.

In an embodiment, two inner side walls of the U-shaped clamping groove 52 parallel to each other are provided with semicircular limiting grooves 53 arranged coaxially with the left rotating shaft 221. The advantages are that: on one hand, the limiting groove 53 can limit the bearing, and on the other hand, the limiting groove 53 can increase the contact area between the left rotating shaft 221 and the inner wall of the U-shaped clamping groove 52, so that the clamping effect is improved.

In an embodiment, the tightening mechanism includes a locking handle 61 and a connecting pin 62, two parallel inner side walls of the U-shaped clamping groove 52 are vertically provided with through holes in a penetrating manner, the connecting pin 62 is arranged in the two through holes in a penetrating manner, and one end of the connecting pin 62 is integrally provided with a limiting block 621 for limiting the end of the connecting pin to enter the through holes; one end of the locking handle 61 is hinged to the other end of the connecting pin 62, and an eccentric wheel structure 611 for controlling the tightness of the U-shaped clamping groove 52 is integrally arranged at one end of the locking handle 61 hinged to the connecting pin 62.

The number of the adjusting screws 71 and the number of the screw mounting holes 222 are preferably four, so that the spring mounting seat 42 is fixed on the right side plate 22, and the spring mounting seat 42 is prevented from rotating along with the rotation of the winding drum 1; the number and thickness of the adjusting shims are not limited, and according to specific needs, for example, when a distance of 1mm to the left is required, the adjusting shims may be set to 1mm and installed in front of the spring mount 42 and the right side plate 22, so that the spring mount 42 moves to the left by a distance of 1 mm; similarly, the adjusting gaskets with different thicknesses can be arranged, so that the position of the spring mounting seat 42 can be adjusted along the left-right direction, the pretightening force of the damping spring 41 can be adjusted, and the rotation speed of the winding drum 1 can be controlled.

In the embodiment, the left end and the right end of the winding drum 1 are both provided with limiting check rings 11, and a winding area is formed between the two limiting check rings 11. The advantages are that: on one hand, the limiting retainer ring 11 can prevent the cable from being clamped on the left rotating shaft 221 and the right rotating shaft 221, so that the normal use is influenced; on the other hand, the winding drum 1 can be rotated through the limit check ring 11, and the operation is simple and convenient.

In the embodiment, a fixing through hole 12 for fixing the thread end is formed in the area, located between the two limiting check rings 11, of the winding drum 1. The advantages are that: one end of the cable can be fixed on the fixing through hole 12, and the use is convenient.

In an embodiment, the bottoms of the left side plate 21 and the right side plate 22 are connected with the supporting legs 8 in a lifting manner through the ball hinges 80 which are installed in a threaded manner, and the lifting function of the supporting legs 8 can be realized by adjusting the nuts 81 on the ball hinges 80; the support leg 8 is provided with a screw fixing hole 82 so that the support leg 8 can be fixed on the ground by a screw. The advantages are that: the ball hinge 80 can realize the self-adaptive capacity of different installation surfaces, and is convenient for adjusting the height of the support leg 8 by adjusting the screw cap on the ball hinge 80, thereby improving the overall stability in the use process.

In the embodiment, the left side plate 21 and the right side plate 22 are both provided with a handle 9. The advantages are that: is convenient to move.

The working principle is as follows: firstly, according to the actual situation of the ground, the height of the supporting leg 8 is adjusted by adjusting the nut 81, the bottom surface of the supporting leg 8 is adapted to different installation surfaces under the action of the ball hinge 80, and then the fixing between the supporting leg 8 and the installation surfaces is completed by the screws passing through the screw fixing holes 82, so that the stability of the reel device in the use process is ensured. Then, the locking handle 61 is pulled up (pulled up refers to the clockwise direction of the drawing sheet in fig. 4, and pressed down refers to the counterclockwise direction of the drawing sheet in fig. 4, and the same applies below), so that the clamping force between the U-shaped clamping grooves 52 and clamped on the left rotating shaft 221 gradually decreases until the clamping force disappears, the damping spring 41 is compressed by rotating the limit retainer 11, and then the clamping force between the U-shaped clamping grooves 52 and clamped on the left rotating shaft 221 gradually increases by pressing down the locking handle 61 until the left rotating shaft 221 is locked (i.e., the winding drum 1 is locked). Then, one end of the cable is fixed on the winding drum 1 through the fixing through hole 12, and the locking handle 61 is pulled up, at this time, under the restoring force of the damping spring 41, the winding drum 1 rotates in the opposite direction (that is, the winding drum 1 rotates), so that the cable is wound on the winding drum 1, and the automatic wire winding process is completed. Finally, when the cable needs to be paid off, the tip of the cable is pulled manually or mechanically (in the process, the damping spring 41 is gradually contracted), and after the cable is in a proper length, the locking handle 61 is pressed down to prevent the cable from automatically withdrawing; after the use, can pull up again locking handle 61 can accomplish automatic receipts line (when not using, can press down again locking handle 61 locks left pivot 221 prevents that the maloperation makes reel 1 takes place to rotate). In addition, when the pretightening force of the damping spring 41 needs to be increased, or the elastic restoring force of the damping spring 41 gradually decreases as the service time increases, the adjusting gasket (not shown in the drawing) with a proper thickness is sleeved on the adjusting screw 71 and located between the spring mounting seat 42 and the right side plate 22, so that the spring mounting is deviated to the left relative to the right side plate 22 by a distance equal to the thickness of the adjusting gasket, the pretightening force of the damping spring 41 is increased, and the rotation speed of the winding drum 1 is increased; similarly, if the rotation speed of the winding drum 1 is found to be too high, the thickness of the adjusting shim can be reduced appropriately, so as to reduce the rotation speed of the winding drum 1. The reel device is simple to operate, reasonable in layout, simple and compact in overall structure, light in weight and low in cost.

The above description is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
