Embodiment 1

[0035] Example 1: See Figure 1-6 , a glass fiber reinforced plastic optical cable protective sleeve, comprising an outer tube 1, an inner tube 3 is arranged inside the outer tube 1, a glass fiber layer 2 is fixedly connected between the outer tube 1 and the inner tube 3, and the inner tube 3 There are three sets of fixed line support structures inside;

[0036] see Figure 1-6 , a glass fiber reinforced plastic optical cable protective sleeve also includes a fixed line support structure, the fixed line support structure includes a fixed ring 4, the fixed ring 4 is fixedly connected to the inside of the inner tube 3, and the inside of the fixed ring 4 is fixedly connected with a soft The rubber ring 5, the inside of the soft rubber ring 5 is provided with multiple sets of wire grooves 6, and the inside of the wire groove 6 is sleeved with an anti-wear sleeve 7;

[0037] The slots 6 are arranged at equal intervals, and the outer diameter of the fixed ring 4 is consistent with...

Embodiment 2

[0039] Embodiment 2: One side of the outer tube 1 is provided with a sealing structure 8 for the connecting port. The sealing structure 8 for the connecting port is composed of a connecting head 801, a connecting ring 802, a fixed ring 803 and a silicone ring 804. The connecting head 801 is fixedly connected to the outer tube 1. On one side, the external thread of the connector 801 is connected with a connecting ring 802, the middle position inside the connecting ring 802 is fixedly connected with a fixed ring 803, and the two sides of the connecting ring 802 are fixedly connected with a silicone ring 804;

[0040] The external threads of the connector 801 and the internal threads of the connecting ring 802 coincide with each other, and the silicone ring 804 is symmetrically distributed about the vertical center line of the fixed ring 803;

[0041] Specifically, such as figure 1 and Figure 4 As shown, the connecting ring 802 is put on the outside of the connecting head 801, ...

Embodiment 3

[0042] Embodiment 3: Two sets of internal moisture absorbing structures 9 are provided at the bottom of the inner tube 3. The internal moisture absorbing structures 9 are composed of a box body 901, a refueling door 902, a through plate 903 and a color-changing silica gel 904. The box body 901 It is fixedly connected to the bottom end inside the inner tube 3, and the inside of the box body 901 is provided with multiple sets of color-changing silica gel 904, and one side of the top of the box body 901 is movably hinged with a refueling door 902, and the inside of the top of the box body 901 is provided with a through plate 903 ;

[0043] Small holes are evenly arranged inside the through plate 903, and the color-changing silica gel 904 is arranged at equal intervals;

[0044] Specifically, such as figure 1 and image 3 As shown, when there is moisture accumulation inside the pipeline, the external humid air enters the inside of the box body 901 through the small hole on the t...

Abstract

The invention discloses a glass fiber reinforced plastic optical cable protection bushing, and particularly relates to the technical field of pipelines. The glass fiber reinforced plastic optical cable protection bushing comprises an outer pipe, wherein an inner pipe is arranged in the outer pipe, an outer protection structure is arranged outside the outer pipe, and three groups of wire fixing support structures are arranged in the inner pipe. According to the invention, through the arrangement of the fixing ring, the soft rubber rings, the wire groove and the anti-abrasion sleeve, in the using process, after a cable penetrates into the bushing, the cable is directly erected on the soft rubber rings, the position of the cable is raised through the soft rubber rings, the contact area of the cable and the pipe wall is reduced, and the interior of the pipeline is cut into multiple spaces through the multiple soft rubber rings, so that even if water entering and other conditions exist in the interior, the interior of the whole pipeline cannot be affected; and the wire groove provides space for clamping of the cable, the anti-abrasion sleeve can reduce abrasion of the cable in the dragging process, and the fixing ring provides stable support for the whole structure, so that the function of lifting and fixing the cable in the pipeline is achieved.

Description

technical field [0001] The invention relates to the technical field of pipes, in particular to a glass fiber reinforced plastic optical cable protective sleeve. Background technique [0002] Since the information revolution, with the development of society and the advancement of science and technology, the application of computers has penetrated all aspects of the country's science and technology and people's livelihood. The laying of the corresponding medium cable for signal transmission is one of the key projects. Most of the cable laying is buried underground. Affected by the geology and local environment, the cable protection sleeve is very vulnerable to damage, which requires its own material and function to be able to cope with various emergencies, which has also led to the continuous upgrading and improvement of the cable protection sleeve. Production technology and optimization of internal structure. [0003] In the process of realizing the present invention, the in...
