Description

Technical Field

[0001] The utility model relates to the technical field of cable protection tubes, in particular to a separated pressure-resistant cable protection tube. Background Art

[0002] A search of the publication (announcement) number: CN217656381U discloses a separable CPVC power cable protection tube, including a tube body, wherein the tube body is assembled from a first tube body and a second tube body, a plurality of partition plates are arranged on the first tube body, a connecting structure is arranged on the first tube body and the second tube body, and the second tube body is provided with a mounting seat adapted to the partition plate, and the mounting seat is provided with a groove; the utility model adopts the partition plate to divide the cavity formed by the first tube body and the second tube body into a plurality of independent cavity channels through the arrangement of the partition plate, so that the cables do not affect each other, and at the same time the partition plate also plays a supporting role on the tube body, thereby increasing the overall compressive strength of the tube body.

[0003] During use of the above invention, the first tube body is placed in the groove, the cable to be placed is placed in the channel formed by the corresponding partition plate, the second tube body is lowered and aligned with the first tube body, and in the process of pressing the second tube body downward to the first tube body, the arc strip contacts the inclined surface on the clamping strip, causing the clamping strip to be squeezed and shifted inward until the second tube body is completely close to the first tube body, and the clamping strip is no longer squeezed by the arc strip and returns to its original state, so that the clamping block fits tightly with the clamping groove, and the connection between the tube bodies can be connected by commonly used fasteners. However, this connection method still has certain defects, that is, when the cable needs to be replaced later, the clamping strip returns to its original state, and the clamping block fits tightly with the clamping groove. Then, when the first tube body and the second pipe are disassembled, the entire clamping strip needs to be deformed by tools, and this operation method is not convenient for overall disassembly.

[0004] To this end, we propose a partitioned pressure-resistant cable protection tube. Utility Model Content
