Description
Technical Field
The utility model relates to a cable unwrapping wire equipment technical field specifically is a cable unwrapping wire pulley.
Background
The cable paying-off pulley is mainly used for playing a role in protecting when laying cable leads, and the movement of the cable is promoted through the rotation of the pulley, so that time and labor are saved. However, the moving and paying-off of the cable are not always constant in the cable laying process, the cable can fall off when moving on the pulley, the cable is locked on the pulley, and the cable is very troublesome and inconvenient to mount on the pulley and separate from the pulley.
Chinese patent CN 206432628U discloses "a cable unwrapping wire pulley", and it can prevent deviating from of cable to a certain extent, but it is that dead weight through the part presses the cable on the draw-in groove, and the effect of anticreep is unreliable, and the cable still has the risk of deviating from.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem who exists among the background art, the utility model provides a cable unwrapping wire pulley, its easy operation, and can realize the auto-lock, it is more firm to the fixed of cable.
The utility model provides a technical scheme that its technical problem adopted is:
a cable payout sheave comprising:
the frame, frame upper end opening.
The roller is arranged on the frame and comprises a first roller, a second roller and a third roller which are arranged in a triangular mode, and a paying-off channel is formed between the rollers.
The first roller and the second roller are fixedly connected with the frame; the lower end of the third roller is hinged with the frame, and the upper end of the third roller is connected with the frame through a first connecting rod and a second connecting rod; the first connecting rod is hinged with the third roller, and the second connecting rod is hinged with the frame; the first connecting rod is hinged with the second connecting rod, and the hinged position between the first connecting rod and the second connecting rod is positioned at the lower end of the contact surface of the first connecting rod and the second connecting rod.
Preferably, the first connecting rod and the second connecting rod are hinged through a spring hinge.
Preferably, a magnet is arranged on a contact surface between the first connecting rod and the second connecting rod.
Preferably, the frame is provided with a hole.
The utility model has the advantages that:
the device is simple to operate, the opening and closing of the device can be realized by lifting the first connecting rod and the second connecting rod, and when the device is closed, the first connecting rod and the second connecting rod can form self-locking, so that the roller can fix the cable more firmly.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural view of the present invention when closed;
fig. 2 is a schematic structural view when the utility model is opened;
fig. 3 is a partially enlarged view at a position a of fig. 2.
In the figure:
1. the magnetic roller comprises a frame, 2, a first roller, 3, a first connecting rod, 4, a second connecting rod, 5, a second roller, 6, a third roller, 7, a hole and 8 magnets.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
As shown in fig. 1 and 2, a cable paying out pulley includes: frame 1, rollers, first link 3 and second link 4.
The upper end of the frame 1 is opened; the rollers are arranged on the frame 1 and comprise a first roller 2, a second roller 5 and a third roller 6 which are arranged in a triangular shape, and a paying-off channel is formed between the rollers.
The first roller 2 and the second roller 5 are fixedly connected with the frame 1; the lower end of the third roller 6 is hinged with the frame 1, and the upper end of the third roller 6 is connected with the frame 1 through a first connecting rod 3 and a second connecting rod 4; the first connecting rod 3 is hinged with the third roller 6, and the second connecting rod 4 is hinged with the frame 1; articulated between first connecting rod 3 and the second connecting rod 4, articulated position between first connecting rod 3 and the second connecting rod 4 is located the lower extreme of its contact surface, loses external force, because the reason of self gravity, first connecting rod 3 and second connecting rod 4 can resume to the horizontality, and when first connecting rod 3 and second connecting rod 4 were in the horizontality, its contact surface butt each other formed the auto-lock. The third roller 6 is fixed in position and cannot move.
Optionally, the first link 3 and the second link 4 are hinged through a spring hinge, and the spring hinge has a self-resetting function, so that the first link 3 and the second link 4 can form a self-locking state in which contact surfaces are mutually abutted even without the gravity of the first link 3 and the second link 4.
As shown in fig. 3, optionally, a magnet 8 is installed on the contact surface between the first link 3 and the second link 4, and a magnetic attraction force is provided between the magnets 8, so that the first link 3 and the second link 4 can form a self-locking state in which the contact surfaces abut against each other even without the gravity of the first link 3 and the second link 4.
In the embodiment, the frame 1 is provided with the holes 7, the holes 7 can play a role in reducing the weight of the frame 1, and the frame is more convenient to carry through the holes 7.
The specific use method comprises the following steps:
the first connecting rod 3 and the second connecting rod 4 are lifted upwards by external force, so that the device is opened. The cable is placed in the payout channel between the rollers.
When the external force is released, the first link 3 and the second link 4 are restored to the horizontal state, and a self-locking state in which the contact surfaces are abutted against each other can be formed. At the moment, the position of the third roller 6 is firmly fixed, and the cable is effectively prevented from being separated.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
