Description
Technical Field
The utility model belongs to the technical field of the optical cable, concretely relates to sheath evacuating device based on cable core.
Background
The existing sheath vacuumizing device is poor in air exhaust effect, the whole structure needs to customize different sealing rings for different cable cores, external air which is caused by poor sealing can enter the device, and meanwhile, the negative pressure of the inner mold region cannot be guaranteed to be larger than the negative pressure of other regions in the air exhaust process.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that to the not enough of above-mentioned prior art, a sheath evacuating device based on cable core is provided.
In order to realize the technical purpose, the utility model discloses the technical scheme who takes does:
a sheath evacuating device based on cable core, wherein: including the base that is equipped with the import, by outer and interior centre form base and the evacuation registration arm that has connected gradually on the base, leave the clearance between centre form base and the evacuation registration arm, the through-hole has been seted up on the one side lateral wall that the centre form base is close to the base, be provided with the connecting pipe in the through-hole, the one end that the base was kept away from to the centre form base is connected with the centre form, the export has been seted up to the one end that the centre form base was kept away from to the centre form.
In order to optimize the technical scheme, the specific measures adopted further comprise:
furthermore, the inlet and the outlet are both circular, the aperture of the inlet is larger than that of the outlet, and the circle centers of the inlets and the outlets are positioned on the same horizontal straight line.
Further, the inner mold is of a trapezoidal structure with a large left side and a small right side.
Furthermore, a gap is reserved between one side of the vacuumizing positioning pipe, which is far away from the base, and the inner die.
Furthermore, the connecting pipe is in threaded connection with the inner die base, the inner die base is in threaded connection with the base, and the vacuumizing positioning pipe is in threaded connection with the base.
Furthermore, the connecting pipe is provided with an external thread and is fixedly connected with an external air extractor through the external thread.
The utility model has the advantages that:
the utility model relates to a sheath evacuating device based on cable core through the rational arrangement of evacuation and centre form base to and the trapezoidal structure of centre form, make the evacuation effect better, make the regional negative pressure value of centre form be greater than other regions simultaneously, closely wrap up the plastics of molten state and create better environment on the cable core for one process down.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
The reference signs are: the vacuum-pumping device comprises an inlet 1, a base 2, an internal mold base 3, a vacuum-pumping positioning pipe 4, a connecting pipe 5, an internal mold 6 and an outlet 7.
Detailed Description
Embodiments of the present invention are described in further detail below with reference to the accompanying drawings.
As shown in fig. 1, the utility model relates to a sheath evacuating device based on cable core, including the base 2 that is equipped with import 1, by outer and interior threaded connection has centre form base 3 and evacuation registration arm 4 in proper order on the base 2, leave the clearance between centre form base 3 and the evacuation registration arm 4, the through-hole has been seted up on centre form base 3 is close to one side lateral wall of base 2, through-hole female connection has connecting pipe 5, and connecting pipe 5 is provided with the external screw thread, is connected fixedly through external screw thread and external air extractor.
The one end that centre form base 3 kept away from base 2 is connected with centre form 6, and centre form 6 is the big right trapezium structure in a left side, leaves the clearance between one side that base 2 was kept away from to evacuation registration arm 4 and centre form 6, centre form 6 one end of keeping away from centre form base 3 has seted up export 7, and wherein import 1 and export 7 are circular, the aperture of import 1 is greater than the aperture of export 7, and the centre of a circle is in on the same horizontal straight line for the cable core can keep the horizontal straight state.
The utility model discloses a use method as follows:
divide the centre form region into I region, divide the 4 inner regions of evacuation registration arm into III region, divide the clearance between evacuation registration arm 4 and centre form base 3 into II region, at first bleed through the external screw thread connection air extractor of connecting pipe 5, then successively be imported, III region, I region, II region and through-hole by the gas of bleeding in proper order, increased the resistance that external gas got into the cavity, reduced the air quantity that leaks to get into the cavity in unit interval. The negative pressure in the I region is increased.
Above only the utility model discloses an it is preferred embodiment, the utility model discloses a scope of protection not only limits in above-mentioned embodiment, and the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, a plurality of modifications and decorations without departing from the principle of the present invention should be considered as the protection scope of the present invention.
