Embodiment 1

[0038] Such as Figure 1-4 As shown, a high-impact pillow-shaped composite casing includes a pipe body 1 and a plurality of anti-impact ribs 2 arranged on the outer wall of the pipe body 1, two adjacent anti-impact ribs 2 are arranged at intervals, and the anti-impact reinforcement The outer circumference of the ribs 2 is square and the four corners of the impact-resistant ribs 2 are recessed to form fillets 3 . Both ends of the pipe body 1 have connecting parts 4 extending outward.

[0039] The outer wall of the pipe body 1 is provided with a plurality of anti-impact ribs 2, and the structure of the anti-impact ribs 2 is used and the corners are recessed to form an inner fillet 3, which improves the compressive capacity of the anti-impact ribs 2 and improves the impact resistance of the high-impact pillow. The compressive strength of the composite casing in the vertical direction. At the same time, if the pressures received by multiple anti-impact ribs 2 are different, the fo...

Embodiment 2

[0045] Such as Figure 5 As shown, a sleeve assembly includes a plurality of high-impact pillow-shaped composite sleeves described in Embodiment 1, and two adjacent high-impact pillow-shaped composite sleeves communicate and abut against each other.

[0046] The bushing assembly is easy to assemble and is suitable for protecting cables over long and short distances. Further, the pipe bodies 1 of two adjacent high-impact pillow-shaped composite casings communicate and abut against each other

[0047] The junction of two adjacent high-impact pillow-shaped composite sleeves is welded by heat fusion.

[0048] With the above technical solution, the joints of two adjacent high-impact pillow-shaped composite bushings are tightly bonded, avoiding separation to cause the cables to be exposed and causing damage to the cables, and at the same time avoiding air / water infiltration into the bushing components to accelerate cable aging. Further, the two adjacent high-impact pillow-shaped c...

Embodiment 3

[0050] The difference between this embodiment 3 and embodiment 2 is:

[0051] Such as Image 6 As shown, the sleeve assembly also includes a buckle assembly, which is fastened on the outer walls of two adjacent high-impact pillow-shaped composite sleeves, and the buckle assembly includes a buckle pipe fitting 5 and an abutment The sealing ring (not shown in the figure) on the inner wall of the buckle pipe 5 is used for fastening two adjacent high-impact pillow-shaped composite sleeves.

[0052] Adopt the above-mentioned technical scheme to make the joints of two adjacent high-impact pillow-shaped composite sleeves tightly bonded, avoiding separation and causing the cable to be exposed and causing damage to the cable, and at the same time avoiding air / water infiltration into the sleeve assembly to accelerate cable aging . Further, one end of the buckle pipe fitting 5 is engaged with the impact rib 2 of the first high-impact pillow-shaped composite casing 6 close to the second...

Abstract

The invention relates to the technical field of protective sleeves, in particular to a high-impact-resistance pillow-shaped composite sleeve and a sleeve assembly. The high-impact-resistance pillow-shaped composite sleeve comprises a sleeve body and a plurality of impact-resistant reinforcing ribs arranged on the outer wall of the sleeve body. Every two adjacent impact-resistant reinforcing ribs are arranged at intervals. The periphery of each impact-resistant reinforcing rib is square, and the four corners of each impact-resistant reinforcing rib are sunken to form filleted corners. The two ends of the sleeve body extend outwards to form connecting parts. By utilizing the structure, the impact resistance can be improved. The outer wall of the sleeve body is sleeved with a plurality of impact-resistant reinforcing ribs. Because of the structure of the impact-resistant reinforcing ribs and the filleted corners formed by sinking the corners of the reinforcing ribs, the compression resistance of the impact-resistant reinforcing ribs is improved, and the compressive strength of the high-impact-resistance pillow-shaped composite sleeve in the vertical direction is also improved. Meanwhile, if the pressures borne by the multiple impact-resistant reinforcing ribs are different, the pressures can be transmitted to the sleeve body and evenly dispersed and counteracted, and therefore, the ring stiffness and the impact strength of the high-impact-resistance pillow-shaped composite sleeve are improved.

Description

technical field [0001] The invention relates to the technical field of protective sleeves, in particular to a high-impact pillow-shaped composite sleeve and a sleeve assembly. Background technique [0002] In order to increase the compressive performance of the casing, many manufacturers will set a plurality of rectangular reinforcing blocks on the outer periphery of the casing to enhance the compressive performance of the casing. However, during use, the corners of the reinforcing block are often broken due to the uneven force on the two adjacent sides, resulting in insufficient impact resistance of the casing. Contents of the invention [0003] In order to overcome the shortcomings and deficiencies in the prior art, the purpose of the present invention is to provide a high-impact pillow-shaped composite sleeve, which can improve its own impact resistance. [0004] Another object of the present invention is to provide a bushing assembly, which is easy to assemble and sui...
