Detailed Description
The following describes in further detail the embodiments of the present invention with reference to the drawings and examples. The following examples are illustrative of the invention and are not intended to limit the scope of the invention.
Example 1:
referring to fig. 1 to 7, the cable cutter of this embodiment includes a connecting cylinder 1 and a fixing ring 2, the fixing ring is fixedly arranged at the top end of the connecting cylinder, a cutting line 3 is arranged at the inner side of the fixing ring, one end of the cutting line is arranged on the fixing ring, the other end of the cutting line penetrates through the side wall of the fixing ring and extends into the connecting cylinder, and the cable cutter further includes a cutting line driving device for driving the cutting line in the connecting cylinder to move.
The cutting line driving device comprises an outer sleeve 4 sleeved on the outer side of the connecting cylinder, the top end of the outer sleeve is open, and the bottom end of the outer sleeve is closed through a bottom cover 5. The inner wall of the outer sleeve is provided with an internal thread, the outer wall of the connecting cylinder is provided with an external thread matched with the internal thread, and the outer sleeve is matched with the connecting cylinder through threads.
One end of the cutting line passes through the perforation 6 at the bottom of the fixed ring and is connected with a first limit ball 7, and the size of the first limit ball is larger than the inner diameter of the perforation, so that the limit of the cutting line is realized.
The other end of the cutting line sequentially passes through the other perforation at the bottom of the fixed ring and the perforation on the bottom cover and is connected with the second limiting ball 8. In order to realize the fixation of the cutting line and the bottom cover, a locking sleeve 9 can be arranged on the bottom cover, the locking sleeve is sleeved on the outer side of the cutting line, and the bottom end of the locking sleeve is fixedly arranged on the bottom cover. The locking sleeve is formed by encircling a plurality of locking plates with certain elastic top ends at certain intervals, and the locking ring 10 which is in threaded connection with the locking plates is arranged on the outer side of the locking sleeve. The inner diameter of the locking ring is slightly smaller than the outer diameter of the locking sleeve, so that after the locking ring is connected with the locking sleeve, each locking plate of the locking sleeve is inclined inwards under the extrusion of the locking ring, and the cutting line is locked on the bottom cover.
In addition, the fixing of the cutting line and the bottom cover can be realized by welding, arranging a limit ball connected with the cutting line on the inner side of the bottom cover, a connecting ring connected with the cutting line and the like, and the detailed description is omitted here.
In this embodiment, the connecting tube, the outer sleeve, the fixing ring and other parts are made of metal, plastic or ceramic. The cutting line is a metal wire, preferably a steel wire, having elasticity.
When the cable is used, an operator sequentially passes through the end part of the cable through the fixing ring and the arc body formed by surrounding the cutting line. The operator then rotates the outer sleeve outwardly by rotation. Along with the rotation of the outer sleeve, the bottom cover and the end part of the cutting line arranged on the bottom cover move along with the rotation of the outer sleeve, so that the cutting line is gradually contacted with the cable. As the cable is tightened, it gradually applies pressure to the jacket of the cable and cuts until the jacket is completely cut.
In order to strengthen the cutting effect, after the cutting line is tightened on the surface of the cable, an operator can drive the fixing ring through the outer sleeve to enable the fixing ring to integrally rotate back and forth for a certain angle, so that the outer sleeve of the cable is completely separated from the cable core, and the wire stripping is completed.
After the wire stripping is completed, the operator reversely rotates the outer sleeve so as to restore the outer sleeve to the original position. Because the cutting line has certain elasticity, after the outer sleeve is restored to the original position, the cutting line is restored to the original shape under the action of self elasticity so as to be cut next time.
In order to realize the protection to the fixed ring and the cutting line, the two sides of the fixed ring can be respectively provided with a retainer ring 11, and the middle hole of the retainer ring is an eccentric round hole eccentric with the middle shaft of the fixed ring, so that the cutting line at the bottom can protrude out of the surface of the fixed ring, and further can be in close contact with the surface of a cable.
Further, in order to achieve positioning of the cutting line, the inner surface of the fixing ring may be provided with a ring groove 12, in which the cutting line may be disposed.
In order to facilitate connection, the bottom of the fixing ring is provided with a boss 13, and the top end of the connecting cylinder can be fixedly connected with the boss in a welding, screwing mode and the like.
In summary, the cable cutter of the embodiment sets the cutting line on the inner side of the fixing ring, and drives the end of the cutting line to move through the cutting line driving device, so that the cutting line on the inner side of the fixing ring is gradually tightened, and further the cable is cut until the outer sleeve of the cable is separated from the cable core. Compared with the existing mode of stripping wires through the scissors behind the wire stripper, the wire stripper is not easy to break a cable core, is applicable to stripping wires of cables with different types and different diameters, and is very convenient to operate.
Example 2:
the cable cutter of this embodiment is substantially identical to the cable cutter of the first embodiment, except that some of its components have been modified.
Specifically, the cutting line of the cable cutter of the embodiment is a diamond wire saw, that is, a wire with diamond plated on the surface. The diamond on the surface of the steel wire makes the cutting line easier to cut the cable jacket, and the cutting efficiency is higher.
Example 3:
the cable cutter of the present embodiment is substantially identical to the cable cutter of the first embodiment, except that the materials of the cutting line and the fixing ring are different from each other.
Specifically, the cutting line of the cable cutter in this embodiment is a heating steel wire. The two ends of the heating steel wire are respectively connected with an external power supply through wires, and therefore the heating steel wire can realize the thermal cutting of the cable jacket through heat during cutting.
Because the outer sleeve is generally made of plastic materials, and the cable is made of metal materials, the heating wire is extremely easy to thermally cut the outer sleeve and can not cut the cable core of the metal materials, so that the cutting effect is better.
In order to realize insulation, in this embodiment, the fixing ring, the connecting cylinder, the outer sleeve and the bottom cover are all made of ceramic, and the outer wall of the fixing ring, the connecting cylinder, the outer sleeve and the bottom cover can be provided with a protective shell made of plastic or other insulating materials to realize insulation and protection functions. The two ends of the cutting line can be respectively connected with an external power supply through wires. Specifically, a socket can be arranged on the bottom cover, and two ends of the cutting line are respectively connected with metal electrodes in the socket through wires, so that connection with an external power supply is realized.
Example 4:
referring to fig. 8, the cable cutter of the present embodiment is substantially identical to that of the first embodiment except that the cutting wire driving device thereof has a certain difference therefrom.
Specifically, the cable cutter of the embodiment includes a drum 14 disposed in the connecting cylinder, one end of a central shaft of the drum is erected on the connecting cylinder, and the other end of the central shaft passes through a side wall of the connecting cylinder and is connected with a knob 15. The end part of the cutting line is fixedly arranged on the winding drum and can be wound in the wire groove on the surface of the winding drum, so that the driving of the cutting line is realized.
When the cutting line tightening device is particularly used, an operator can rotate the winding drum through the knob so as to enable the cutting line to be wound on the winding drum, and therefore tightening of the cutting line is achieved. After cutting is finished, the operator reversely rotates the knob.
In this embodiment, the bottom end of the connecting cylinder 1 may be closed to protect the internal components.
