Description
Technical Field
The utility model relates to a spool field specifically indicates to have a can brake winding and unwinding devices for spool.
Background
Spool is a tool used to wind wire or cable. Traditional spool is when unreeling silk or rope, if the condition of the pine silk appears easily at too fast, consequently some spool can set up the depression bar that is used for compressing tightly wire or wire rope between its curb plate now, and the depression bar passes through the spring and also the curb plate is connected to can avoid the pine silk when using. However, when the spool needs to recover the wire or rope, the pressing structure can cause obstruction, which affects the efficiency of wire recovery.
The utility model discloses a problem design one kind is used for the braking winding and unwinding devices of I-shaped wheel to foretell prior art exists is the utility model discloses the purpose of research.
SUMMERY OF THE UTILITY MODEL
To the problem that above-mentioned prior art exists, the utility model provides a can brake winding and unwinding devices for I-shaped wheel can effectively solve the problem that above-mentioned prior art exists.
The technical scheme of the utility model is that:
a braking retractable device for a spool comprises a base, the spool and a supporting mechanism corresponding to the spool, wherein the spool comprises two side plates and a shaft core, a plurality of ratchets are arranged on the outer ring of the side plate of the spool, a braking mechanism corresponding to the spool is arranged on the base, the braking mechanism comprises two positioning plates, the two positioning plates are respectively arranged in front of the two side plates of the spool, sliding grooves and sliding blocks arranged on the sliding grooves are arranged at the positions of the positioning plates corresponding to the ratchets, and return springs are arranged between the sliding blocks and the front ends of the sliding grooves; pawls corresponding to the ratchets are hinged to the sliding blocks, springs are connected between the pawls and the sliding blocks, and limiting blocks corresponding to the pawls are arranged on the sliding blocks; the movable rotating shaft is rotatably arranged between the sliding blocks, and the fixed rotating shaft is arranged below the positioning plate corresponding to the movable rotating shaft.
And the two ends of the movable rotating shaft and the fixed rotating shaft are matched with the rotating device through corresponding bearings to be arranged on the corresponding sliding block and the corresponding positioning plate.
The supporting mechanism comprises a fixed shaft penetrating through the shaft core and two supporting plates for supporting the fixed shaft.
The utility model has the advantages that:
when the utility model is not used, the pawl of the braking mechanism is pressed against the ratchet of the side plate of the spool, so that the spool can not rotate anticlockwise to discharge wires; when the wire releasing device is used, the head end of the metal wire releases the wire through the fixed rotating shaft and the movable rotating shaft, so that the movable rotating shaft can be pulled forwards while the metal wire is stressed, the pawl hinged to the sliding block leaves the ratchet on the side plate of the spool, and the spool can rotate anticlockwise to release the wire; when the metal wire is stopped to be pulled by external force, the sliding block of the braking mechanism can be quickly reset under the action of the reset spring, so that the pawl is abutted against the ratchet of the spool, the braking effect is realized, and the wire loosening is prevented. And when the spool rotates clockwise to take up the wire, the pawl can not block the spool. The utility model is not only simple in structure, convenient to use moreover can solve the problem that the I-shaped wheel exists when receiving and releasing.
