Looks build harmonious city good for habitation, and a large amount of cable is placed into underground, due to the humid environment of underground, various corrosive substances compared with
More, higher to the sealing waterproof performance requirement of cable, traditional cable is only anti-using being socketed in outer layer with water-proof protection device
Water rubber layer, but it does not have external force protective capability, and traditional water proof rubber layer is weaker in junction waterproof performance, only
It is the sealing ring crimping consolidation of two single connectors, weaker by side pressure ability, sealing effect is bad.
Summary of the invention
It is mentioned above in the background art to solve the purpose of the present invention is to provide a kind of cable water-proof protection device
Problem, possessed beneficial effect is: the novel shape is succinct, and waterproof pressure-resistant ability is strong, and junction sealing effect is good, uses the longevity
Life length.
To achieve the above object, the invention provides the following technical scheme: a kind of cable water-proof protection device, including connection
Bolt head, main pipe, sealing bulge loop, connection card slot and rubber soft-jointing ring, the coupling bar head are fixed on main pipe by joining ring
Left side, the coupling bar head are fixed with sealing bulge loop along side, on the right side of the main pipe by handover ring with connect pullover phase
Even, the main pipe is made of liner layer, steel spiral protection layer and outer water proof rubber layer, the handover ring on the right side of the main pipe
On be fixed with connection card slot, inside connection pullover, the connection card slot inner bottom is provided with bullet for the connection card slot setting
Piece is provided with packer ring on the elastic slice, and the packer ring is fixed on connection card by the rubber soft-jointing ring of outer ring
On slot inner sidewall, seal groove is provided in the middle part of the packer ring.
Preferably, the liner layer outer ring is provided with steel spiral protection layer, fixes on the outside of the steel spiral protection layer
There is outer water proof rubber layer.
Preferably, it is connected between the connection card slot and connection pullover for gap.
Preferably, pass through surface between the external screw thread on the internal screw thread and coupling bar head outer wall on the connection pullover inner wall
Contact is fixedly connected.
Preferably, it is connected between the sealing bulge loop on the seal groove and coupling bar head for interference.
Compared with prior art, the beneficial effects of the present invention are:
1, the novel main pipe is set as three layers, and liner layer is rubber layer, and quality is more soft, can realize when by external force
Buffering effect, effective protection cable are not destroyed, and middle part is set as steel spiral protection layer, and when annulus stress can be by the power of concentration
Being dispersed to whole body is unlikely to deform annulus, can effectively keep out external pressure, outer water proof rubber layer is arranged in outer layer can be entire to cable
Environment plays the role of sealing, and the water or chemicals placed in environment enter.
2, the novel connection type is easy to operate in such a way that coupling bar head is connect with connector sleeve head thread, is easy to
Installation.
3, connect between the novel packer ring on coupling bar head in setting sealing bulge loop and connection card slot for interference
It connects, sealing effect is excellent, will not be leaked by when larger lateral force, and bullet is arranged between packer ring and connection card slot
Piece so that packer ring holds extrapolability to sealing bulge loop always, and then guarantees that connection pullover will not be loose from coupling bar head
It is dynamic.

Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
Fig. 1-6 is please referred to, a kind of embodiment provided by the invention: a kind of cable water-proof protection device, including coupling bar
