Description

Technical Field

[0001] The utility model relates to the technical field of waterproof sleeves, in particular to a waterproof sleeve that is easy to install. Background Art

[0002] When pipelines pass through railways, roads, streets, etc., in order to prevent the pipelines from being crushed by loads, protective casings are installed on the outside of the pipelines, such as large-diameter concrete pipes, large-diameter steel pipes, etc., to prevent external forces (loads) from directly acting on the outer wall of the pipelines and causing damage to the pipelines. Waterproof casings are also called wall-penetrating casings and wall-penetrating pipes. Waterproof casings are divided into rigid waterproof casings and flexible waterproof casings. The two are mainly used in different places. Flexible waterproof casings are mainly used in places with high requirements such as civil defense walls and pools. Rigid waterproof casings are generally used in basements and other places where pipelines need to pass through pipelines. Flexible waterproof casings are generally suitable for structures where pipelines pass through walls that are subject to vibration or have strict waterproofing requirements. After the casing part is processed, a primer is applied to its outer wall (the primer includes camphor or cold primer oil).

[0003] The prior art can install a waterproof sleeve on a wall, but the prior art waterproof sleeve is not fixed when embedded in the wall, and is easy to move forward or backward or rotate when hit by external force, thereby causing dislocation and deviating from the embedded position. Therefore, those skilled in the art provide a method for facilitating the installation of a waterproof sleeve to solve the problems raised in the above background technology. Summary of the invention

[0007] As a further solution of the utility model: rubber grooves are provided on the inner walls on both sides of the connecting ring, wherein the rubber head can be stuck in the rubber grooves, a first annular slot is provided on the upper end of the first fixing ring, and a flange is provided above the first fixing ring.

[0008] As a further solution of the utility model: the lower end of the flange is fixedly connected with a first insert ring, wherein the first insert ring is inserted into a first annular slot, and a plurality of groups of bolts are arranged in the outer ring direction of the first annular slot, wherein the lower ends of the bolts are fixedly connected to the upper surface of the first fixing ring.

[0009] As a further solution of the utility model: the flange is provided with a plurality of groups of through holes, wherein the bolts all pass through the through holes, so as to limit the position of the flange.

[0010] As a further solution of the utility model: the upper ends of the bolts are all threadedly connected with nuts, wherein the nuts are located above the flange, and the nuts can move up and down on the bolts, and the nuts can fix the flange on the first fixing ring.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When pre-embedding the waterproof casing in the wall, you can drill screw holes on both sides of the pre-embedded hole, and then drive the fixing screws into the screw holes to fix the waterproof casing on the wall. This makes it easier to install and fix, and can also prevent the waterproof casing from rotating after installation.

[0013] 2. When assembling other parts of the waterproof casing, insert the flange onto the bolt, align the insertion hole with the bolt, insert the first insert ring into the first annular slot, and fix the flange onto the first fixing ring through a nut. Then, thread the third threaded ring into the third threaded groove, and then fix the connecting ring onto the third fixing ring. This makes assembly quick and easy.

[0014] 3. After passing the pipe through the waterproof casing, you can turn the fixing screw B inward to fix the pipe so that it is stable in the waterproof casing. The rubber head acts as a buffer to prevent the pipe from being squeezed. BRIEF DESCRIPTION OF THE DRAWINGS
