[0005] The above-mentioned technical objective of the utility model is achieved through the following technical scheme: a network cable pay-off device comprises a base plate, the upper end surface of the base plate is vertically installed with two side plates, a pay-off roller and a reciprocating screw rod are rotatably arranged between the two side plates, the outer thread of the reciprocating screw rod is provided with a movable plate at the lower end of the movable plate, and a thread end clamping structure is provided at the upper end, the left side of the left end side plate is provided with a driving device for driving the reciprocating screw rod and the pay-off roller to rotate, and the right side of the right end side plate is provided with a limiting component for fixing the pay-off roller, the thread end clamping structure comprises a bracket fixed to the upper end of the movable plate, a threading groove is provided in the bracket, a one-way screw rod is provided with a one-way screw rod at the upper end thread, and a pressing frame located in the threading groove is provided at the lower end of the one-way screw rod, and an arc-shaped pressing groove is provided on the side opposite to the threading groove of the pressing frame, and the left and right side walls of the threading groove are provided with guide grooves for the pressing frame to slide up and down.

[0006] By adopting the above technical solution, when paying out the wire, the cable end is passed through the wire threading groove of the bracket, and the driving device controls the pay-off roller and the reciprocating screw to rotate simultaneously. During the pay-off process, the movable plate pushes the bracket to slide left and right smoothly, so that the cable on the pay-off roller is paid out neatly and stably. After the cable is cut, the pay-off roller is fixed by the limiting component to prevent the pay-off roller from rotating due to other factors. At the same time, the unidirectional screw is rotated to push the bottom pressure frame downward, so that the cable end is pressed and fixed, which can prevent the cable from loosening and knotting.

[0007] The utility model is further configured as follows: a handle is arranged at the upper end of the one-way screw rod, the lower end is rotatably connected to the pressing frame through a bearing, and a soft cushion is arranged on the inner side of the arc-shaped pressing groove.

[0008] By adopting the above technical solution, the one-way screw rod can be rotated conveniently by holding the handle, the setting of the bearing enables the pressing frame to be smoothly raised and lowered under the influence of the guide grooves on both sides, and the setting of the soft pad improves the fixing effect of the cable end.

[0009] The utility model is further configured as follows: the sliding limiter comprises a slide rail mounted on the upper surface of the bottom plate, and a slider slidably matched with the slide rail is mounted at the bottom of the movable plate.

[0010] By adopting the above technical solution, when the movable plate is subjected to the thread force, the slider at the lower end is always in a state of sliding left and right translation on the slide rail, so that the movable plate can drive the wire end clamping structure to translate, making the wire release process smoother and preventing the wire from being chaotically tangled.

[0011] The utility model is further configured as follows: the limiting component includes a fixed block vertically installed on the right side plate, an electric push rod is installed on the fixed block, a gear is installed on the right end of the pay-off roller, and an arc-shaped gear ring meshing with the gear is installed on the output end of the electric push rod.

[0012] By adopting the above technical solution, when the pay-off roller needs to be fixed, the electric push rod drives the arc-shaped gear ring to move so that it meshes with the gear, thereby fixing the gear and positioning the pay-off roller to prevent the pay-off roller from rotating due to external influences.

[0013] The utility model is further configured as follows: the driving device includes a motor installed on the left side of the top of the base plate, the output end of the motor is connected to a reciprocating screw rod, the reciprocating screw rod and the left side of the outer wall of the pay-off roller are both provided with synchronous wheels, and a synchronous belt is installed between the two synchronous wheels.

[0014] By adopting the above technical solution, the motor controls the rotation of the reciprocating screw, which can drive the movable plate to move back and forth periodically to make the wire payout more stable. At the same time, the two synchronous wheels rotate under the action of the synchronous belt, which can make the wire payout roller rotate and perform the wire payout operation.

[0015] The beneficial effects of the utility model are:

[0016] 1. In the utility model, when paying out the wire, the motor controls the rotation of the reciprocating screw rod, and the two synchronous wheels rotate under the action of the synchronous belt, so that the wire-paying roller can rotate to carry out the wire-paying operation. During the wire-paying process, the cable end passes through the threading groove of the bracket, and the reciprocating screw rod pushes the movable plate and the bracket as a whole to move back and forth periodically left and right, so that the wire-paying is more stable and the cable knotting problem can be avoided during the wire-paying process.

[0017] 2. In the utility model, after the wire-laying is completed, the electric push rod drives the arc-shaped gear ring to move and mesh with the gear, thereby fixing the gear and positioning the wire-laying roller to prevent the wire-laying roller from rotating due to external influences. At the same time, the one-way screw is rotated to push the bottom pressure frame downward so that the cable end is pressed and fixed, which can prevent the cable from loosening and tangling, making the device more suitable for wire-laying operations.
