Description

Technical Field

[0001] This utility model relates to the technical field of wall-mounted elbows for concealed gas pipes, specifically a wall-mounted elbow for concealed gas pipes. Background Technology

[0002] A gas concealed pipe elbow is a special pipe fitting used in the installation of gas pipelines. It is mainly used to make turns inside the wall so that gas pipelines can be arranged inside the wall. This elbow is usually made by fitting the elbow cavity onto the corrugated gas pipe opening to form a sealed whole.

[0003] The existing design of the wall-mounted elbow for concealed gas pipes requires bending the pipe body before it can be inserted into the casing, which makes placement inconvenient and inflexible. Therefore, its structure needs to be improved.

[0004] Now, a new type of concealed gas pipe bend leading out of the wall is proposed to solve the above problem. Summary of the Invention

[0005] The purpose of this utility model is to provide a wall-mounted elbow for concealed gas pipes, in order to solve the problems mentioned in the background art, which require bending the pipe body to be inserted into the pipe shell, resulting in inconvenience and inflexibility during placement, and the problem that the corrugated pipe will rub against the elbow and cause jamming if a secondary pipe extraction is required after installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A wall-mounted elbow for a concealed gas pipe includes a fixed shell and a circular pipe shell. The circular pipe shell is fixedly connected to the right side of the fixed shell. A first connecting block is fixedly connected to the left side of the front and rear ends of the fixed shell. A first mounting groove is provided inside one side of the first connecting block. A second fixed frame is provided on the left side of the top of the fixed shell. Mounting blocks are fixedly connected to the left side of the front and rear ends of the second fixed frame. A sliding roller is provided inside the second fixed frame. A first fixed frame is provided on the right side of the top of the fixed shell. A first locking block is fixedly connected to the front and rear ends of the bottom of the first fixed frame. A second connecting block is fixedly connected to the front and rear ends of the bottom left side of the first fixed frame. A first locking groove is provided inside the front and rear ends of the fixed shell. A stainless steel cover plate is locked inside the first fixed frame.

[0008] As a further technical solution of this utility model, the mounting block fits into the interior of the first mounting groove, and the second fixing frame is detachable from the fixing shell through the mounting block.

[0009] As a further technical solution of this utility model, a first fixing cover is provided at the top of the fixing shell, a second fixing cover is provided on one side of the first fixing cover, a second arc-shaped groove is provided on the right side of the first fixing cover, and a first arc-shaped groove is provided on the left side of the second fixing cover. The diameters of the first arc-shaped groove and the second arc-shaped groove are the same.

[0010] As a further technical solution of this utility model, the first fixing frame is detachable from the top of the fixing shell by the first locking block, and the first locking block matches the position of the first locking groove.

[0011] As a further technical solution of this utility model, a second locking block is fixedly connected to the front and rear ends of the right side of the first fixing cover, and a second locking groove is provided at the front and rear ends of the bottom of the second fixing cover.

[0012] As a further technical solution of this utility model, the second card block is positioned to match the second card slot, and the second card block is detachable and embedded inside the second card slot.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the gas concealed pipe wall-exit elbow not only eliminates the need for bending when the pipe is installed into the housing, facilitating modular assembly, but also allows for easy disassembly and assembly of the front cover, facilitating pipe positioning; after installation, if secondary pipe extraction is required, the sliding roller of the second fixing frame can guide and reduce friction between the pipe and the elbow, solving the problem of pipe jamming during secondary pipe extraction and causing installation difficulties; moreover, the stainless steel cover plate is secured to the first fixing frame, preventing the elbow from being punctured by a nail gun or drill bit after it is embedded in the wall.

[0014] The system comprises a fixed shell, a round tube shell, a first connecting block, a first mounting groove, a second fixed frame, a mounting block, a first fixing frame, a first locking block, a second connecting block, a second fixed frame, and a stainless steel cover plate. By utilizing the relationship between the mounting block embedded inside the first mounting groove, it is convenient to disassemble the second fixed frame and the fixed shell. When installing the pipe, it can be directly inserted into the fixed shell and the round tube shell from the top without bending the pipe body. The mounting block of the second fixed frame is inserted into the first mounting groove of the first connecting block for fixation. Then, the stainless steel cover plate is snapped into the first fixed frame, and the first locking block at the bottom of the first fixed frame is snapped into the first locking groove, which facilitates separate assembly.

[0015] By providing a first fixed cover, a second fixed cover, a first arc-shaped groove, a second arc-shaped groove, a second locking block, and a second locking groove, after installation, the first fixed cover and the second fixed cover can be locked together by the first locking block and the second locking block, and then locked into the fixed shell, which facilitates fixing the pipe body from the front end, making the installation of the pipe body more convenient.
