[0002] Casing is an insulating device that introduces live conductors into electrical equipment or through walls. The former is called electrical casing, and the latter is called wall casing. Casing is usually used in building basements and is an iron ring used to protect pipes or facilitate pipe installation. Casings are classified into rigid casing, flexible waterproof casing, steel pipe casing and iron casing. Composite casing is composed of different materials and has the characteristics of corrosion resistance, high strength, light weight, heat resistance, insulation and easy processing. It is widely used in chemical, petroleum, natural gas, electricity and other fields. However, in actual use, the existing casing has the problem of reduced local structural strength when bending, and the internal pipeline is prone to breakage. In addition, the casing has insufficient impact resistance and is prone to breakage due to uneven force.

[0003] In order to solve the deficiencies of the existing technology, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a high-impact pillow-shaped composite casing and casing assembly [201910877700.1], which includes a pipe body and a plurality of impact-resistant reinforcement ribs arranged on the outer wall of the pipe body, two adjacent impact-resistant reinforcement ribs are arranged at intervals, the outer periphery of the impact-resistant reinforcement ribs is square and the four corners of the impact-resistant reinforcement ribs are concave to form inner fillets, and both ends of the pipe body have connecting parts extending outward.

DETAILED DESCRIPTION

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0023] like Figure 1-4 As shown, a high-strength composite casing includes a main body 1 for cables or fluids to pass through. The main body 1 is usually made of a composite material that can withstand bending torque. A protective sleeve 2 is sleeved on the outside of the main body 1 for local reinforcement. A hollow opening 3 is opened on the protective sleeve 2. Reinforcement ribs 4 are arranged between the hollow openings 3 of the protective sleeve 2. Compared with the conventional closed pipe structure, the hollow opening 3 and the reinforcement ribs 4 can enhance its anti-pulling ability. Assembly components 5 are respectively arranged at the end of the protective sleeve 2 and the outside of the bending part to install the protective sleeve 2 at the bending position such as the corner of the wall. A locking component 6 opposite to the main body 1 is arranged on the inside of the bending part of the protective sleeve 2. The locking component 6 applies a locking torque to prevent the main body 1 from circumferential or axial misalignment.

[0024] Specifically, the protective sleeve 2 includes a main sleeve body 21, and the ports of the main sleeve body 21 are respectively provided with a reinforcing frame 22 integrally formed therewith, and an extrusion assembly is provided between the reinforcing frame 22 and the main pipe body 1. The extrusion assembly is adjusted manually, so that the reinforcing frame 22 applies an extrusion torque to the main pipe body 1, so that both ends of the protective sleeve 2 have a high structural stability.

[0025] In depth, the extrusion assembly includes an extrusion sleeve 23 threadedly connected to the outside of the reinforcement frame opening 22, an anti-slip stripe 24 is arranged on the outside of the extrusion sleeve 23, a guide slope 25 is arranged on the inside of the reinforcement frame opening 22, and the extrusion sleeve 23 has an extrusion block 26 extending into the reinforcement frame opening 22, and the extrusion block 26 fits and presses against the guide slope 25. The extrusion sleeve 23 is manually rotated, and the extrusion sleeve 23 as a whole moves axially along the protective sleeve 2. During the movement, the extrusion block 26 approaches or moves away from the central axis of the extrusion sleeve 23 under the action of the guide slope 25, thereby achieving the fixing or separation of the protective sleeve 2 and the main body 1.

[0026] Furthermore, in order to ensure the tensile strength of the protective sleeve 2, the hollow opening 3 is hexagonal, and the reinforcing ribs 4 are arranged at the edge of the hollow opening 3 to further improve its structural strength.

[0027] Furthermore, support bars 31 are provided between adjacent hollow openings 3, and extend axially along the protective sleeve 2. The support bars 31 engage with the axial limiter 62 to slide and limit the axial limiter 62, and the support bars 31 are symmetrically arranged relative to the central axis of the protective sleeve 2.

[0028] In addition, the assembly component 5 includes an assembly seat body 51 arranged at the end of the protective sleeve 2 and the outer side of the bend, and the assembly seat body 51 has an assembly foot 52 that fits the plane, and an assembly hole 53 is opened on the assembly foot 52. The assembly foot 52 is fixed to the wall through a screw, and the assembly seat body 51 and the assembly foot 52 are arranged in pairs relative to the protective sleeve 2.

[0029] At the same time, unlike the conventional locking structure, the locking assembly 6 in the present application includes a locking tube 61 arranged on the inner side of the bend of the protective sleeve 2, the locking tube 61 is made of a flexible material, and an axial stopper 62 is arranged between the locking tube 61 and the protective sleeve 2. The locking tube 61 can improve the tightness of the engagement between the axial stopper 62 and the protective sleeve 2.

[0030] It can be seen that the axial stopper 62 adopts a movable assembly structure, which includes a stopper ring 63 arranged on the inner side of the protective sleeve 2, a stopper groove 64 is provided on the outer side of the stopper ring 63 to engage with the hollow opening 3, and locking protrusions 65 are distributed on the inner side of the stopper ring 63 to press against the locking tube 61. When the stopper ring 63 slides axially, the locking protrusions 65 press against the locking protrusions 65, and as the locking tube 61 deforms, it is pressed and fixed with the main body 1.

[0031] Obviously, the main body 1 is made of flexible material to ensure bending performance, and the protective sleeve 2 is made of hard material to maintain the overall structural strength. A single main body 1 can be equipped with multiple protective sleeves 2 to meet its continuous bending requirements.

[0032] Preferably, the protective sleeve 2 has a bending angle of 0-60°, and limiting the bending angle prevents the main body 1 from bending too much to affect internal cables and fluid transmission.

[0033] In summary, the principle of this embodiment is that a protective sleeve 2 is sleeved on the outside of the bending part of the main body 1 for local reinforcement, the protective sleeve 2 is fixed in position by an assembly component 5, and the locking component 6 on the inside applies a locking torque to the main body 1 to prevent the main body 1 from breaking due to bending stress.

[0034] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.

[0035] Although this article uses more terms such as main body 1, protective sleeve 2, main sleeve body 21, reinforcement frame opening 22, extrusion sleeve 23, anti-slip stripe 24, guide slope 25, extrusion block 26, hollow opening 3, support bar 31, reinforcement rib 4, assembly component 5, assembly seat 51, assembly foot 52, assembly hole 53, locking component 6, locking tube 61, axial limiter 62, limit ring 63, limit groove 64, locking protrusion 65, etc., it does not exclude the possibility of using other terms.
