Further, the fixture includes the fixture guide section set gradually and fixture limit section；The fixture guide section
Shape matched with the bell-mouthed inner wall of J-type pipe；The fixture limit section is set to the larger diameter end of fixture guide section.
Further, the fixture further includes the fixture linkage section that fixture limit section rear end is arranged in.
Further, the fixture linkage section includes recess portion and protrusion, for being mutually twisted with sea cable bending restrictor.
Further, the sea cable bending restrictor is the chain that at least two bent-segment limiter blocks are mutually twisted composition
Shape structure.
Further, the fixture is by polyurethane one-time cast-forming.
Further, the fixture is polyurethane fixture.
The utility model has the beneficial effects that
1) for the fixture of the utility model using whole, Ha Fushi structure, part is less, installs extremely quick.
2) fixture of the utility model is integrally formed by casting, and process is few, high-efficient, reduces the production cycle, is improved and is closed
Lattice rate has stronger delivery advantage.
3) fixture of the utility model has guiding, limit and connection function simultaneously, limits fixture in J-type pipe horn mouth
Interior position, while guaranteeing that sea cable is in J tube hub, directly judge whether whole device is installed to by the size of tractive force
Position.
4) fixture has abandoned traditional metal structure using fixture, and device quality is smaller, is guaranteed using ocean grade polyurethane
While intensity, there is more excellent sea water corrosion resistant.
5) the utility model entire length is reduced, and only uses polyurethane material, and half can be saved in batch production
Cost.
Detailed description of the invention
In order to more clearly illustrate the technical scheme in the embodiment of the utility model, will make below to required in embodiment
Attached drawing is simply introduced, it should be apparent that, the accompanying drawings in the following description is only some realities recorded in the utility model

Fig. 5 is the structural schematic diagram of liner.
Specific embodiment
The technical solution of the utility model will be clearly and completely described by specific embodiment below.
It as shown in Figs. 1-5, is a kind of monoblock type J protection of pipe device of the utility model, including fixture 1, liner 2, locking
Screw 3 and locking nut 4.The fixture 1 of the utility model is Ha Fushi to half structure, and mounting hole, two folders are arranged on fixture 1
Tool 1 is connected and fixed by lock screw 3 and locking nut 4.
As shown in figure 4, fixture 1 includes that fixture guide section 11 and fixture limit section 12.Guide section 11 be located at fixture 1 most before
End, appearance profile are matched with the shape of J-type pipe horn mouth 6, are installed to the inner wall after J-type pipe horn mouth 6 with J-type pipe horn mouth 6
Fitting, it is ensured that sea cable is in J tube hub position.It can directly judge whether whole device is installed to by the size of tractive force
Position.Fixture limit section 12 is located at the rear portion of fixture guide section 11, for limiting position of the fixture 1 in J-type pipe horn mouth 6.Such as
Shown in Fig. 2-4, in order to be used cooperatively fixture 1 with sea cable bending restrictor 7, fixture 1 is in the rear end of fixture limit section 12
Fixture linkage section 13 can also be set.Fixture linkage section 13 includes recess portion and protrusion.The sea cable bending restrictor 7 of the utility model
It is the chain structure that at least two bent-segment limiter blocks are mutually twisted composition, sea cable bending restrictor is engaged in fixture linkage section
On 13.Sea cable bending restrictor one end jockey 1, the other end contacts with each other with the sea bed surface of a wound, the minimum allowed by itself
Bending radius protects sea cable will not overbending in hanging section.
As shown in Figure 1, the utility model is in the inside of fixture 1 setting liner 2, liner 2 is located at fixture 1 and submarine cable 5
Between, liner 2 is rubber material or ocean grade polyurethane.2 one side of insertion liner can increase sea cable and folder on the inside of fixture 1
The friction of tool, lateral pressure of the less fixture of another aspect to sea cable.
As shown in figure 5, be provided on the liner 2 of the utility model liner boss 21, with fixture 1 on the inside of be arranged it is recessed
Concave portion position 14 matches.When installation, liner boss 21 is embedded in depressed area 14, carries out axially position.
The fixture of the utility model uses straight polymer material, preferably using ocean grade polyurethane (polymer) material.
Ocean grade polyurethane has high rigidity (82D), high-intensitive, low-density (1.15g/cm3) characteristic, does not increase in seawater to sea cable
Add weight bearing；High antiseptic property can guarantee 25 years or more service life.It is big, corrosion-resistant to solve original metal device quality
The disadvantages such as property is low.
The installation procedure of the utility model:
Firstly, the surplus according to required for sea cable and the length of J-type pipe etc., judge that whole device is mounted in sea cable
Position, and identify；Two halves liner 2 is separately mounted to inside two halves fixture 1,2 liner boss 21 and fixture 1 are padded
Clamp recess position 14 mutually it is stuck；Fixture 1 and liner 2 that two halves are combined hold the mark position of sea cable tightly respectively, and
Two halves fixture 1 is tightened into (screw-down torque is determined according to screw material and size etc.) using lock screw 3 and locking nut 4.
Then, at the fixture linkage section 13 of fixture 1, connection sea cable bending restrictor module may be selected, as needed really
The length of Dinghai cable bending restrictor 7.Sea cable bending restrictor 7 installs sea cable traction device after the installation is completed, in sea cable end
(traction net cover or drawing head etc.)
Finally, the entirety of mounted grip device and bending restrictor, as sea cable is drawn together to J-type pipe horn mouth
6 ends limit the fixture of fixture 1 and are bonded to each other inside section 12 and J-type pipe horn mouth 6, and whole device installs.
