Description

Cable with prevent rolling over cover

Technical Field

The invention relates to the technical field of cables, in particular to a cable with an anti-folding sleeve.

Background

Cable is a generic term for optical cables, electrical cables, and the like. The cable has many applications, is mainly used for controlling installation, connecting equipment, transmitting power and other multiple functions, is a common and indispensable object in daily life, and needs to be installed carefully because the cable is electrified.

In actual production life, some cables are particularly dangerous to use due to skin cracking caused by long-term bending, and in factory operation and household circuits, electrical components in a distribution box are often overloaded and burnt due to the problems of line aging and the like, and once the distribution box is burnt, the distribution box is easy to diffuse along with lines due to the fact that the distribution box is electrified and a plurality of plastic parts are arranged, so that great economic loss is caused, and the cable with the anti-folding sleeve is quite dangerous.

Disclosure of Invention

The invention provides a cable with an anti-folding sleeve, which solves the problems that a surface skin is cracked due to long-term bending of the cable, and electrical elements are overloaded and burnt due to line aging.

In order to achieve the purpose, the invention adopts the following technical scheme:

the utility model provides a cable with prevent rolling over cover, includes plastic casing and cable, plastic casing inner wall fixed mounting has two fixed blocks that are the symmetric distribution, two rotate between the fixed block and install first toothed disc, plastic casing inner wall fixed mounting has two fixed plates that are the symmetric distribution, the threaded rod is installed to the fixed plate screw thread, just the threaded rod runs through the fixed plate, two mutual correspondences the one end that the threaded rod is close to each other is rotated and is installed fixed cardboard, two install the cable between the fixed cardboard, fixed cardboard one end fixed mounting is kept away from to the threaded rod has the stopper, the outside cover of threaded rod is equipped with rather than threaded connection's second toothed disc, and the second toothed disc is located between stopper and the fixed plate.

Preferably, the outer wall of the first gear disc is fixedly provided with a sliding block, the other end of the sliding block extends to the outside of the plastic shell, and the clamping device is controlled by sliding of the sliding block.

Preferably, set up on the plastic casing with sliding block assorted sliding tray for the sliding block slides on sliding tray.

Preferably, the cable is provided with a rubber skin, a heat insulation layer, a flame retardant layer and a wire harness, and the rubber skin, the heat insulation layer, the flame retardant layer and the wire harness are wrapped in sequence from outside to inside, so that the cable has good fireproof performance, and the wire harness inside is protected from being damaged.

Preferably, the sliding block is the setting of character cut in bas-relief shape rubber material for can control the sliding and fixed of sliding block on plastic casing.

The invention has the beneficial effects that:

1. through the plastic casing that sets up in the cable outside, the inside clamping device who sets up of plastic casing simultaneously for the cable can not buckle in plastic casing inside, and clamping device's setting makes inside cable more stable, has also prevented the cable and has buckled in plastic casing inside, thereby has prevented the fracture of rubber epidermis, makes the effect more obvious.

2. Through the setting of increasing insulating layer and fire-retardant layer for the cable is inside for the cable has good fire behavior, has protected inside pencil not destroyed.

To sum up, the device is effectual to have solved the cable and has buckled the problem that makes the rubber epidermis fracture, provides the guarantee for people's safety, and the device has fine fire resistance simultaneously, and simple structure, convenient to use, suitable popularization.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.

Referring to fig. 1-4, a cable with an anti-folding sleeve comprises a plastic shell 1 and a cable, wherein two fixed blocks 13 which are symmetrically distributed are fixedly installed on the inner wall of the plastic shell 1, a first gear disc 2 is rotatably installed between the two fixed blocks 13, two fixed plates 7 which are symmetrically distributed are fixedly installed on the inner wall of the plastic shell 1, a threaded rod 5 is installed on the fixed plates 7 in a threaded manner, the threaded rod 5 penetrates through the fixed plates 7, a fixed clamping plate 8 is rotatably installed at one end, close to each other, of the two mutually corresponding threaded rods 5, a cable is installed between the two fixed clamping plates 8, a limiting block 6 is fixedly installed at one end, far away from the fixed clamping plate 8, of the threaded rod 5, a second gear disc 4 which is in threaded connection with the threaded rod 5 is sleeved outside the threaded rod 5, the second gear disc 4 is located between the limiting block 6 and the, and the other end of the sliding block 3 extends to the outside of the plastic shell 1, and a sliding groove matched with the sliding block 3 is formed in the plastic shell 1.

Referring to fig. 1, the cable is provided with a rubber skin 9, a heat insulation layer 10, a flame retardant layer 11 and a wire harness 12, and the rubber skin 9, the heat insulation layer 10, the flame retardant layer 11 and the wire harness 12 are wrapped in sequence from outside to inside, so that the cable has good fireproof performance, and the wire harness 12 inside is protected from being damaged.

Referring to fig. 4, the sliding block 3 is made of a rubber material having a shape of a Chinese character 'ao', so that the sliding and fixing of the sliding block 3 on the plastic case 1 can be controlled.

The working principle is as follows: the device pencil 12 outside parcel has fire-retardant layer 11, insulating layer 10 and rubber epidermis 9, make the cable have fine fire behavior, inside pencil 12 has not been protected by destruction, the cable of accomplishing the installation is placed between fixed cardboard 8, later press from both sides tight sliding block 3 both sides hard a little, thereby make sliding block 3 both sides to stir sliding block 3 to inside extrusion and make sliding block 3 drive first toothed disc 2, then drive second toothed disc 4 through first toothed disc 2 and rotate, second toothed disc 4 rotates and drives threaded rod 5 flexible between fixed plate 7, thereby it presss from both sides tight cable to drive fixed cardboard 8 flexible, loosen the hand at last, make sliding block 3 fix current position, guarantee that clamping device can not become flexible in the use, thereby can prevent the cable fracture of buckling, the effect is more obvious.
