Description

Technical Field

[0001] The utility model belongs to the technical field of cables, in particular to an underground cable. Background Art

[0002] Underground cables are generally grooved in the ground and fixed to the ground through the grooves. They are often sheared and squeezed due to external forces, causing the cables to be damaged. Therefore, underground cables are generally designed as armored cables to increase the strength of the cable's outer protective layer so that it can withstand stronger external forces and prevent external forces from damaging the cable core.

[0003] However, this type of cable is directly and tightly fitted with the outer armor during use, and the inner diameter of the armor needs to match the outer wall of the cable. The application scope of the armor is limited and cannot be widely used with cables of different diameters.

[0004] Therefore, we proposed underground cables to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the problems existing in the prior art and proposes the following technical solutions:

[0006] The buried cable includes a cable body and an armored shell installed on the outer wall of the cable body; the inner wall of the armored shell is provided with multiple groups of elastic components at equal distances along the arc direction, and the elastic components are composed of an abutting inner plate abutting the outer wall of the cable body, a movable inner plate installed on the abutting inner plate, an elastic member installed on the inner side of the open cavity in the movable inner plate, and multiple groups of open cavities opened at equal distances on the inner wall of the armored shell.

[0007] With the cooperation of the elastic component, the armored shell can be adapted to the installation operation of different cable bodies, thereby improving the application range of the armored shell and ensuring the adaptation efficiency of the armored shell during use.

[0008] As a preferred embodiment of the above technical solution, the elastic component also includes a sliding rail opened on the inner side wall of the cavity, and there are sliders sliding in the sliding rails, and the sliders are installed on both sides of the top of the movable inner plate; with the coordinated use of the elastic potential energy of the elastic part, the movable inner plate can move smoothly inside the cavity.

[0009] As a preferred embodiment of the above technical solution, a protective pad is glued to the inner wall of the abutting inner plate, and the protective pad abuts against the outer wall of the cable body; the protective pad forms a gap between the abutting inner plate and the cable body to avoid direct contact between the abutting inner plate and the cable body to form wear.

[0010] As a preferred embodiment of the above technical solution, soft pads are glued on both sides of the bottom end of the armored shell; the soft pads form a gap between the outer wall of the bottom end of the armored shell and the ground, avoiding direct contact between the outer wall of the bottom end of the armored shell and the ground to form wear.

[0011] The beneficial effects of the utility model are:

[0012] In this application, with the cooperation of elastic components, the armored casing can be adapted to different cable bodies for installation operations. Combined with the inner groove bottom opened in the ground, the armored casing can stably limit and lock the cable body, thereby improving the applicability of the armored casing and ensuring the adaptation efficiency of the armored casing during use.

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] like Figure 1 and Figure 2 As shown, in the embodiment of the utility model, it includes: a cable body 1 and an armored shell 2 installed on the outer wall of the cable body 1; the armored shell 2 is installed on the outer wall of the cable body 1 with the use of bolts and other tools, so as to increase the pressure resistance of the cable body 1 against the outer wall. The above are all existing technologies, and this application does not protect them this time, so no further details will be given.

[0019] like Figure 1 and Figure 2As shown, the inner wall of the armored shell 2 is provided with multiple groups of elastic components at equal distances along the arc direction, and the elastic components are composed of an abutting inner plate 9 abutting the outer wall of the cable body 1, a movable inner plate 6 installed on the abutting inner plate 9, an elastic member 5 installed inside the movable inner plate 6 on the inner side of the opening 4, and multiple groups of openings 4 opened at equal distances on the inner wall of the armored shell 2. The cable body 1 to be buried is placed inside the armored shell 2, and the outer wall of the cable body 1 is abutted against the abutting inner plate 9. At this time, the armored shell 2 is pressed downward with the elastic potential energy of the elastic member 5, and then the armored shell 2 is locked with the groove wall in the ground with the above-mentioned bolts and other tools. The adaptive installation operation of the armored shell 2 and different cable bodies 1 can be completed.

[0020] It should be noted that if Figure 2 As shown, in this embodiment, a spring is used as an elastic component to force the movable inner plate 6 to move inside the cavity 4, but in some other embodiments, other elastic components such as a reed, an elastic pick, etc. can also be used.

[0021] like Figure 2 As shown, the elastic component also includes a slide rail 8 opened on the inner wall of the cavity 4, and a slider 7 slides in the slide rail 8, and the sliders 7 are installed on both sides of the top of the movable inner plate 6; with the cooperation of the elastic potential energy of the elastic member 5, the movable inner plate 6 can move smoothly inside the cavity 4.

[0022] like Figure 1 and Figure 2 As shown, a protective pad 10 is glued to the inner wall of the abutting inner plate 9, and the protective pad 10 abuts against the outer wall of the cable body 1; the protective pad 10 forms a gap between the abutting inner plate 9 and the cable body 1 to avoid direct contact between the abutting inner plate 9 and the cable body 1 to form wear, wherein the protective pad 10 can be made of other soft materials such as rubber and sponge.

[0023] like Figure 1 As shown, soft pads 3 are glued on both sides of the bottom end of the armored shell 2; the soft pads 3 form a gap between the outer wall of the bottom end of the armored shell 2 and the ground to avoid direct contact between the outer wall of the bottom end of the armored shell 2 and the ground to form wear, wherein the soft pads 3 can be made of other soft materials such as rubber and sponge.

[0024] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
