Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to a retractable and fixable waterproof sleeve. Background Art

[0002] After the construction of a building is completed, water supply and drainage projects need to be constructed inside it, and various pipes need to be laid. In order to avoid water leakage from the contact part of the pipe with the concrete, a waterproof casing needs to be installed at the place where the pipe passes through the concrete to prevent water seepage.

[0003] The current casing structure is simple, and most of them are directly cut and used from existing steel pipes at the construction site. There are also pre-made waterproof casings, but due to differences in the use location and the construction size used, the length of the waterproof casing is sometimes difficult to meet the use requirements. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model discloses a retractable and fixable waterproof sleeve, and the technical scheme adopted is that it includes a first sleeve, a fixing plate, fixing screw holes, a second sleeve, a flange, a telescopic adjustment mechanism, an arc groove and a sealing structure. The right end of the first sleeve is integrally formed with a fixing plate, and a plurality of fixing screw holes are evenly distributed on the fixing plate. The fixing plate is fixed by bolts. During installation, the position of the fixing plate is first fixed by bolts, which can ensure the stability of the installation. The second sleeve is sleeved on the first sleeve, and a flange is provided at the right end thereof. The flange is connected to the fixing plate through a telescopic adjustment mechanism. Under the action of the telescopic adjustment mechanism, the second sleeve can be moved on the first sleeve, and the moving process is stable. Arc grooves are evenly distributed on the outer wall of the first sleeve, and a sealing structure is arranged at the flange to seal the right side contact portion of the first sleeve and the second sleeve, so that after the length of the entire waterproof sleeve is adjusted, it can still maintain good sealing performance.

[0005] As a preferred technical solution of the utility model, the telescopic adjustment mechanism includes a mounting protrusion, a screw, a knob and a fixing column. The mounting protrusions are symmetrically integrated at the outer walls of the upper and lower ends of the flange. A screw is rotatably installed on the left side of the fixing plate, and a fixing column is fixedly installed. The screw is installed in cooperation with the upper mounting protrusion. The knob is fixed at the end of the left protruding end, and the fixing column passes through the through hole opened at the lower mounting protrusion. The screw is driven to rotate by manually rotating the knob so that the mounting protrusion can move along the fixing column, thereby driving the entire second sleeve to move, thereby completing the length adjustment of the entire device.

[0006] As a preferred technical solution of the utility model, the screw rod and the fixing column are both made of stainless steel.

[0007] As a preferred technical solution of the utility model, the sealing structure includes a feeding channel, a sealing plug and an inner circular arc convex plate. Two inner circular arc convex plates are integrally formed on the inner side of the flange. The spacing between the two inner circular arc convex plates is consistent with the width of the circular arc groove. A number of feeding channels are evenly opened on the flange. The feeding channels lead to the space between the two inner circular arc convex plates and are closed by the sealing plug. After the length adjustment is completed, the position between the two inner circular arc convex plates is aligned with the position of the circular arc groove. Adhesive material is added to the inside through the feeding channel to fill the space formed by the circular arc groove and the inner circular arc convex plate, thereby fixing the position and playing a sealing role at the same time.

[0008] As a preferred technical solution of the utility model, the sealing plug is a detachable sealing plug, and the outer wall of the end of the first sleeve located inside the second sleeve has an annular protrusion, which contacts the inner wall of the second sleeve and forms a cavity between it and the inner arc convex plate.

[0009] The beneficial effects of the utility model are as follows: the second sleeve can be moved on the first sleeve through the telescopic adjustment mechanism, so that the length of the entire waterproof sleeve composed of the first sleeve and the second sleeve can be adjusted to meet the construction needs, and the entire adjustment process is stable, and the outer wall of the first sleeve will not be squeezed during the movement. After the adjustment is completed, the sealing structure is used to reinforce and seal the entire device to achieve the anti-leakage function. The entire device is highly practical in actual use scenarios, can adapt to different construction environments, and is easy to operate. BRIEF DESCRIPTION OF THE DRAWINGS
