Description

Technical Field

[0001] The present application relates to the technical field of embedded bushings, and in particular to a through-wall embedded bushing. Background Art

[0002] The embedded casing is a hole reserved for pipes to pass through brick walls, concrete beams, concrete walls and other components. It is suitable for civil air defense, underground engineering, chemical industry, steel, tap water, sewage treatment and other pipelines that require strict waterproofing through walls. Generally, the diameter of the embedded casing is two specifications larger than the diameter of the pipe to pass through the component.

[0003] The existing patent (Announcement No.: CN 206468911 U) discloses a pre-buried wall sleeve, including a wall, a wall panel connected to the wall, a sleeve installed in the wall, a fixing ring connected to the sleeve, the fixing ring is installed above the wall panel, and four self-tapping holes are evenly opened on the fixing ring, and self-tapping screws are installed in the self-tapping holes. The bottom end of the self-tapping screw is fixed in the wall, a filling layer is arranged around the inside of the sleeve, and two elastic support members are arranged in the opening of one end of the sleeve, and the elastic support members are composed of a connecting plate, a spring and a stopper. A drainage pipe is installed in the sleeve, and protective pads are arranged on the opening surfaces of both ends of the sleeve. The utility model has the characteristics of strong integrity, simple structure, effective fixation, improved construction efficiency, and low cost.

[0004] Although the elastic support of the embedded casing can limit the pipeline to a certain extent, it cannot completely limit the pipeline, resulting in low stability of the pipeline and having a certain adverse effect on subsequent construction operations. Utility Model Content

[0005] In response to the shortcomings of the prior art, the present application provides a wall-penetrating embedded sleeve, which has the advantages of being able to completely position pipes of different sizes, increasing the stability of the pipes, and being easy to operate. It solves the problem that the elastic support members of the existing embedded sleeves can play a certain limiting role on the pipes, but cannot completely limit the pipes, resulting in low stability of the pipes and having certain adverse effects on subsequent construction operations.

[0006] To achieve the above-mentioned purpose, the present application provides the following technical solutions: a pre-embedded wall sleeve, comprising a wall body, a wall panel fixedly connected to the front side of the wall body, a sleeve slidably connected to the inside of the wall body, the outer circumferential surface of the sleeve is slidably connected to the inside of the wall panel, four equidistantly arranged fixing seats are fixedly inserted into the inside of the sleeve, a threaded rod is rotatably inserted into the inside of each fixing seat, a threaded pipe is threadedly connected to the outer circumferential surface of the threaded rod, a positioning plate is fixedly connected to the bottom surface of the threaded pipe, an anti-slip strip is provided on the inner wall of the positioning plate, and an outer shell is fixedly sleeved on the outer circumferential surface of the sleeve.

[0007] Through the above scheme, although the elastic support of the existing embedded casing can play a certain limiting role on the pipeline, it cannot completely limit the pipeline, resulting in low stability of the pipeline, which has a certain adverse effect on subsequent construction operations. By setting the second gear, the gear ring and the first gear, the control rod and the threaded rod can be linked. By rotating the control rod, the threaded rod drives the threaded pipe to move, so that the positioning plate and the anti-slip strip can position pipelines of different sizes, thereby increasing the stability of the pipeline.

[0008] Furthermore, a mounting plate is fixedly sleeved on the outer circumferential surface of the sleeve, and four equidistantly arranged bolts are slidably inserted inside the mounting plate, and the outer circumferential surface of each bolt is connected to the inner thread of the wall panel.

[0009] Through the above scheme, the sleeve and the wall panel are connected and installed through the mounting plate and bolts, which is convenient and simple and improves the working efficiency.

[0010] Furthermore, a first limiting ring is fixedly sleeved on the outer circumferential surface of the threaded rod, and the outer circumferential surface of the first limiting ring is rotatably connected to the inside of the fixing seat.

[0011] Through the above solution, the threaded rod is restricted to prevent the threaded rod from sliding and deviating, thereby increasing the stability of the threaded rod movement.

[0012] Furthermore, two limit plates are fixedly connected to the outer circumferential surface of the threaded tube, and the outer surface of each limit plate is slidably connected to the fixing seat via a hollow groove provided inside the fixing seat.

[0013] Through the above solution, the threaded tube is restricted to prevent the threaded tube from rotating along with the threaded rod, thereby increasing the stability of the threaded tube movement.

[0014] Furthermore, a first gear is fixedly sleeved on the outer circumferential surface of the threaded rod, and a gear ring is rotatably connected to the outer circumferential surface of the sleeve via a groove. A base is fixedly connected to the outer circumferential surface of the first gear and the gear ring, and a control rod is rotatably inserted inside the base, and a second gear is fixedly sleeved on the outer circumferential surface of the control rod, and the second gear is meshed with the gear ring.

[0015] Through the above solution, the gear ring is driven to rotate by the control rod and the second gear, so that the gear ring is conveniently controlled.

[0016] Furthermore, a second limiting ring is fixedly sleeved on the outer circumferential surface of the control rod, and the outer circumferential surface of the second limiting ring is rotatably connected to the inside of the base.

[0017] Through the above solution, the control rod is restricted to prevent the control rod from sliding and falling off, thereby increasing the stability of the control rod movement.

[0018] Furthermore, a hand wheel is fixedly sleeved on the outer circumferential surface of the control rod, and the outer circumferential surface of the hand wheel is provided with anti-skid grooves arranged at equal distances.

[0019] The above solution makes it convenient for the user to control the control rod through the hand wheel and avoid hand slipping.

[0020] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0021] The wall-penetrating pre-buried casing, by arranging a second gear, a gear ring and a first gear, enables the control rod and the threaded rod to be linked, and by rotating the control rod, the threaded rod drives the threaded pipe to move, so that the positioning plate and the anti-slip strip clamp the pipe, thereby achieving the effect of being able to position pipes of different sizes in the casing, increasing the stability of the pipe, and facilitating subsequent construction operations, and solving the problem that the elastic support of the existing pre-buried casing cannot completely limit the pipe, resulting in low stability of the pipe.
