Description

Technical Field

[0001] The utility model relates to the technical field of pipe accessories, in particular to a PVC pipe protection cover. Background Art

[0002] PVC pipe is an important pipe with a wide range of uses. After the production of PVC pipe is completed, a protective cover will be installed on the end to prevent dust and debris from entering and protect it from erosion and damage. When the PVC pipe is pre-buried, whether it is pre-buried horizontally or vertically, it is also temporarily sealed and protected by a protective cover to prevent sand, soil and concrete from entering the PVC pipe and avoid blockage.

[0003] Most of the existing PVC pipe protection covers are simple disc-shaped covers that are directly buckled on the ends of the PVC pipes. Although each type of protection cover is produced for the corresponding type of PVC pipe, the volume and thickness of the protection cover are relatively small, while the volume and thickness of the PVC pipe are larger. Under the same ambient temperature changes, the thermal expansion and contraction of the two are different. It is easy for the protection cover to not be tightly covered on the end of the PVC pipe, and it is often easy to fall off, and the protection effect cannot be achieved, which is defective. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a PVC pipe protection cover, which is used to solve the problem that the existing PVC pipe protection cover is not tightly covered and is easy to fall off.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] A PVC pipe protective cover comprises a thickened round cover, wherein the inner wall of the thickened round cover is equidistantly provided with a plurality of ridges parallel to the axis of the thickened round cover and supported on the outer wall of the pipe along the circumferential direction, and the inner side wall of the thickened round cover is also fixedly connected with a plurality of inner clips for supporting on the inner wall of the pipe, and the plurality of inner clips are distributed in a circular array with the axis of the thickened round cover as the array center.

[0007] Preferably, a guiding slope structure is provided on the inner wall of the opening side of the thickened round cover.

[0008] Preferably, one end of the convex ridge corresponding to the guiding inclined surface structure is a smooth curved surface adapted to the guiding inclined surface structure.

[0009] Preferably, the number of the convex ridges and the inner clips are both odd numbers, the convex ridges and the inner clips are staggered and the distances between adjacent convex ridges and inner clips are equal.

[0010] Preferably, the inner clip includes a curved panel, a reinforcing rib and a fixed shaft, both ends of the curved panel are bent toward the axis of the thickened round cover, the reinforcing rib is fixedly connected to one end of the curved panel close to the inner wall of the thickened round cover, and the fixed shaft is fixedly connected between the curved panel and the inner wall of the thickened round cover.

[0011] Preferably, the side of the curved plate away from the axis of the thickened round cover is parallel to the inner wall of the tube, and the fixed axis is parallel to the tangent of the concentric circle where the curved plate corresponds to the thickened round cover.

[0012] Preferably, the thickened round cover, convex ridges, curved panels, reinforcing ribs and fixed shaft form an integrated fixed structure.

[0013] Preferably, anti-skid convex strips are arranged on the outer wall of the thickened round cover along the circumferential direction, and the anti-skid convex strips are arranged intermittently on the circumference of the thickened round cover.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] The utility model adopts a thickened round cover with a thickness close to that of the pipe, and a convex ridge for clamping the outer wall of the pipe is arranged on the circumference of the inner wall of the thickened round cover. The use of the convex ridge increases the gap between the thickened round cover and the inner wall of the pipe, thereby increasing the stress deformation degree of the thickened round cover to adapt to the pipe with a larger deformation amplitude of thermal expansion and contraction. At the same time, an inner clamping piece supported on the inner wall of the pipe is arranged. The overall thickness of the inner clamping piece is small, and it can also adapt to the pipe with thermal expansion and contraction deformation through pressure deformation. The installation tightness is improved by fixing the inside and the outside at the same time, so that it is not easy to fall off, thereby ensuring the protection effect of the pipe, and solving the problem that the existing PVC pipe protection cover is easy to fall off due to loose cover.

[0023] A plurality of inner clips 3 for supporting on the inner wall of the tube 5 are also fixedly connected to the inner wall of the thickened round cover 1. The plurality of inner clips 3 are distributed in a circular array with the axis of the thickened round cover 1 as the array center. The number of ridges 2 and inner clips 3 are both odd numbers. The ridges 2 and inner clips 3 are staggered and the distances between adjacent ridges 2 and inner clips 3 are equal.

[0024] The inner clip 3 includes a curved panel 301, a reinforcing rib 302 and a fixed shaft 303. Both ends of the curved panel 301 are bent toward the axis of the thickened round cover 1. The reinforcing rib 302 is fixedly connected to one end of the curved panel 301 close to the inner wall of the thickened round cover 1. The fixed shaft 303 is fixedly connected between the curved panel 301 and the inner wall of the thickened round cover 1.

[0026] Working principle:

[0027] A thickened round cover 1 is used, and the thickness of the thickened round cover 1 is similar to that of the pipe 5, so that its thermal expansion and contraction degree is close to that of the pipe 5. The ridges 2 on the circumference of the inner wall of the thickened round cover 1 are used to clamp the outer wall of the pipe 5. The ridges 2 increase the gap between the thickened round cover 1 and the inner wall of the pipe 5, so that the degree of stress deformation of the thickened round cover 1 is increased, and it can adapt to the pipe 5 with a larger thermal expansion and contraction deformation through extrusion deformation. At the same time, it is supported on the inner wall of the pipe 5 by the inner clamping piece 3. The inner clamping piece 3 has a small overall thickness and toughness, and can adapt to the thermal expansion and contraction deformation of the pipe 5 through pressure deformation. The thickened round cover 1 is buckled on the end of the pipe 5 by fixing it internally and externally at the same time, which improves the installation tightness, makes it not easy to fall off, and ensures the protection effect of the pipe 5.
