Description

Technical Field

[0001] The present application relates to the technical field of concealed installation of water heater pipelines, and more specifically, to a set of concealed installation devices for water heater pipelines. Background Art

[0002] At present, there are two main ways to install water heater pipes: open installation and concealed installation. Although the open installation method is easy to install, the pipes are exposed, which not only affects the appearance, but also easily causes the pipes to age due to factors such as light and oxidation, shortening the service life. The concealed installation method is beautiful and can avoid the problem of pipe aging;

[0003] However, the existing concealed installation of water heater pipelines generally buries the pipelines directly into the holes and fixes the pipelines with filling glue. Due to the uneven inner wall of the wall hole, there will be a small gap after the pipelines are buried and filled with glue, resulting in a poor sealing effect. The pipelines are easily affected by moisture, which affects the service life of the pipelines. At the same time, installation with filling glue is troublesome and subsequent disassembly may require destruction of the wall structure for inspection, thereby increasing the complexity and cost of maintenance.

[0004] In view of this, we propose a set of concealed installation devices for water heater pipelines. Utility Model Content

[0005] The purpose of the present application is to provide a set of concealed installation devices for water heater pipelines, which solves the technical problems in the above-mentioned background technology and achieves the technical effects of a set of concealed installation devices for water heater pipelines.

[0006] The technical solution of the present application provides a concealed installation device for water heater pipelines, including an internally threaded insert, an outer wall of one end of the internally threaded insert is fixedly connected to a sealing ring, the interior of the internally threaded insert is connected to a threaded sleeve through threaded rotation, the interior of the threaded sleeve is movably inserted with a water heater pipe, the outer movable sleeve of the water heater pipe is provided with a silicone sleeve, one end of the silicone sleeve is fixedly connected to a soft rubber sheet, a plurality of extension grooves are penetrated through the outer wall of the internally threaded insert, a movable bar is slidably connected to the interior of the extension groove, and the end faces of the plurality of movable bars that are away from each other are fixedly connected to a plurality of steel nails.

[0007] Optionally, a silicone gasket is fixedly connected to the end surface of the sealing ring close to the sealing ring, and a guide ring is fixedly connected to one end of the threaded sleeve.

[0008] Optionally, a soft rubber ring is fixedly connected to the end surface of the soft rubber sheet close to the silicone sleeve, and a card slot is opened at one end of the sealing ring, and the card slot corresponds to the soft rubber sheet.

[0009] Optionally, a sealing groove is provided inside the card slot, and the soft rubber ring corresponds to the sealing groove.

[0010] Optionally, limiting grooves are provided on both sides of the inner wall of the extension groove, and both sides of the movable bar are fixedly connected to the limiting bars, and the limiting bars are located inside the limiting grooves.

[0011] One or more technical solutions provided in the technical solution of this application have at least the following technical effects or advantages:

[0012] The present application installs an internal threaded insert in the hole of the wall, and the internal threaded insert is embedded in the wall by steel nails so that the internal threaded insert is firmly fixed in the hole of the wall, which is convenient for the later insertion of the water heater pipe and prevents the outer wall of the hole from being uneven. After the water heater pipe is installed later, the sealing effect is poor, resulting in air leakage in the hole and moisture in the water heater pipe. A silicone sleeve is arranged on the outer wall of the water heater pipe. The silicone sleeve has good elasticity, so that the water heater pipe can be precisely fixed together with the threaded sleeve. It is not easy to loosen, and effectively prevents the water heater pipe from loosening and falling off due to vibration or other external forces, thereby improving the reliability and safety of the device. The soft rubber sheet and soft rubber ring on the silicone sleeve are respectively inserted into the card groove and the sealing groove on the sealing ring. On the one hand, it plays a role in fixing the silicone sleeve to prevent the water heater pipe from loosening. On the other hand, it has a good sealing effect to prevent the inside of the wall hole from being damp, which affects the service life of the water heater pipe. At the same time, the device is simple to install and easy to disassemble, which is convenient for staff to overhaul. BRIEF DESCRIPTION OF THE DRAWINGS
