Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the features and performance of the present invention will be described in further detail with reference to the accompanying drawings and examples.

As shown in fig. 1-3, a portable optical cable joint box comprises an optical cable joint box body and a fiber melting disc fixed inside the optical cable joint box, wherein the optical cable joint box body comprises an upper box cover 14 and a lower box cover 16 which are detachably connected, both ends of the optical cable joint box body are provided with optical cable holes 10, the portable optical cable joint box further comprises a fixed sliding block 13, one side of the fixed sliding block 13 is provided with a rectangular groove which penetrates through both ends of the fixed sliding block 13, the height of the rectangular groove is the same as the thickness of symmetrical edges of both sides of the optical cable joint box body, both sides of the rectangular groove are provided with bosses 17, both upper and lower sides of the symmetrical edges of both sides of the optical cable joint box body are provided with grooves 12, and the bosses 17 are embedded in the grooves 12 so as to enable the fixed sliding block 13 to be slidably connected with the optical cable joint box body.

When the portable optical cable joint box is actually used, firstly, optical fiber preparation work needs to be carried out, then, the prepared optical fibers penetrate through the optical cable holes 10 and are installed on the fiber melting disc and are compressed and fixed, secondly, optical fiber connection and box body sealing need to be carried out, and finally, the upper box cover 14 and the lower box cover 16 are folded and fixed by the fixing slide block 13.

In addition, referring to fig. 5, the fixing slider 13 of the portable optical cable joint box is a rectangular parallelepiped, and a threaded hole 18 is formed at the bottom of the fixing slider 13. The threaded hole 18 is arranged on one side of the bottom surface of the fixed slide block 13 which is not provided with a rectangular groove in the vertical direction. The main purpose of the threaded holes 18 is that the upper cover 14 and the lower cover 16 are fixed by the fixing slider 13, but a small number of fastening bolts are still required for fixing the internal optical cables and for fixing other parts of the box body. Therefore, in order to carry the parts conveniently, the fastening bolts can be placed on the fixed sliding block 13 and taken down when in use. And the shape and size of the bolt holes are different to adapt to different fastening bolt models. Since the fixed slider 13 is formed with a rectangular groove, in order to prevent the position of the screw hole 18 for receiving the bolt from colliding with the position of the rectangular groove, it is necessary to provide the screw hole 18 on a side not corresponding to the rectangular groove in the vertical direction, that is, a bottom surface of a side of the fixed slider 13 which is thick in the vertical direction.

In addition, in order to increase the strength of the box body, it is necessary to provide reinforcing ribs 15 on the outer surfaces of both the upper case lid 14 and the lower case lid 16. Bolt fixing holes 11 may be provided at both ends in consideration of fixing and sealing effects near the cable holes 10 at both ends of the case.

Example 1

As shown in fig. 4, in the portable cable closure described above, with respect to the arrangement of the fixed slider 13, the boss 17 may be inclined in the longitudinal direction in practical use.

The purpose of this arrangement is to reduce the use of bolts by using the fixing slider 13 instead of part of the fastening bolts to fix the cable closure, and to maintain the same fixing degree for the symmetrical sides of the cable closure, but the corresponding disadvantage is that the fastening degree cannot be adjusted as much as the fastening bolts.

To solve this problem, the bosses 17 may be inclined in the longitudinal direction, and the inclination angle needs to be moderate. If the angle is too large, the stationary block 13 will have a section which is too narrow between the two projections 17 to fit into the recess 12. And four fixing sliders 13 may be provided, one set of two for fixing one of the symmetrical edges. When the fixing device is used, the wider side of the boss 17 is embedded into the groove 12, and then all the fixing sliding blocks 13 are pushed slowly, so that the effect of completely fixing the upper box cover 14 and the lower box cover 16 is achieved.
