In addition, through the installation of the sealing ring and the end cover, water and other liquids are effectively prevented from eroding the optical fiber welding spot. Since the present invention can be directly fixed to the optical cable by installing the locker, it is easy to install the present invention under any circumstances, and it is possible to effectively protect the vulnerable portion of the optical fiber welding spot. By choosing an aluminum alloy, synthetic resin or stainless steel material, the optical fiber welding point protector can be prevented from weathering outdoors and the corrosion resistance can be enhanced, thereby extending the life of the optical fiber welding point protector.

Although the optical fiber welding spot protection device solves a partial problem of technical protection, it still has the following disadvantages.

First, since the optical fiber welding spot protection device is divided into two parts, it is difficult to carry and it is easy to lose.

Second, since the optical fiber welding spot protection device is mainly used for protecting the rubber cable, it can not be compatible with the jumper, and thus the protection range is limited.

Third, the thermoplastic tubing length that can be accommodated inside is short. In the case of CN201120015546.6, the acceptable thermoplastic tubing length is only 35 mm.

Fourth, since the mechanical durability is low and the tensile strength is low, the internal cable can not be stably protected.

In the present invention, an optical fiber welding spot protection device is proposed to protect the disadvantages of the prior art.

A second aspect of the present invention relates to an optical fiber welding spot protection device comprising a first body, a second body, a flip cover, and a locking device, wherein the first body is provided with a receiving groove along the body itself, 1 body, both forming a first receiving space for receiving a thermoplastic bushing, the flip cover being connected to a cross-section of the second body so as to be able to rotate at different angles, And the first receiving space and the second receiving space are locked to the first body and both form a second receiving space.

In this embodiment, the locking device includes a cover, which can be screwed into the flip cover and the first body. A U-shaped groove which is easy to rotate in the radial direction is provided on the outer wall of the cover. In the cover, a plurality of anti-rotation grooves are provided in a cross section close to the flip cover and the first body. The flip cover and the first body are respectively provided with threads that match the inner wall of the cover.

One side of the second body is pin-jointed to one side of the first body, and the other side of the second body is snap-connected to the corresponding side of the first body in a fastener manner.

Preferably, a clamping device capable of clamping the thermoplastic tube in the receiving groove of the first body is provided. The clamping device includes a left clamping block and a right clamping block installed symmetrically in the receiving groove, and the left clamping block and the right clamping block move and clamp the thermoplastic tube.

In addition, at least one of a rubber cable and a jumper is fitted in the second accommodation space.
