Abstract
Description
Technical Field
[0001] The utility model provides a plastic pipe fitting joint structure, belonging to the technical field of plastic pipe fitting connection. Background Art
[0002] Plastic pipe fittings are pipe connection parts made of plastic, usually used to connect, divert or divert fluids in a piping system. They can be in various shapes and sizes to meet different piping layouts and needs. Plastic pipe fittings are widely used in industries, construction, agriculture and other fields, and are favored for their lightness, corrosion resistance and easy installation.
[0003] Based on the above, the inventors found that:
[0004] In the prior art, pipe fittings are usually butt-jointed by welding or the like, which can be very strong, but this is only for generally movable pipe fittings. However, if the pipe fittings need to be constantly pulled and moved during use, the pipe fittings need to be cooperated with a limit assembly to prevent the two pipe fittings from falling off.
[0005] Therefore, in view of this, the existing structure is studied and improved, and a plastic pipe joint structure is proposed to solve the above-mentioned problems. Utility Model Content
[0006] The technical problem to be solved by the utility model is that the existing pipe joint structure lacks double limit for pipes that need to be constantly moved, and the connection is not firm.
[0007] In order to solve the above problems, the utility model proposes a technical solution: a plastic pipe fitting joint structure, comprising a plastic pipe fitting 1 and a plastic pipe fitting 2, wherein the plastic pipe fitting 1 is placed inside the plastic pipe fitting 2 and connected through a connecting piece, the connecting piece is sleeved on the plastic pipe fitting 1 and a groove is provided on the plastic pipe fitting 2, the connecting piece is placed in the groove and is threadedly connected to the inner wall of the groove, a limiting component for limiting the plastic pipe fitting 1 is provided inside the plastic pipe fitting 2, and a rubber ring 1 is placed inside the plastic pipe fitting 2.
[0008] Furthermore, a through hole is provided in the middle of the connecting piece and a plastic pipe is placed in the through hole.
[0009] Furthermore, the plastic pipe fitting 1 includes a pipe 1, and a convex block fixedly connected to one side of the pipe, the cross section of the convex block is a right-angle trapezoidal structure, and a rubber ring 2 is sleeved on the pipe 1.
[0010] Furthermore, the limiting assembly includes a limiting block and a spring assembly. The inner walls of the two plastic pipes are provided with limiting grooves and the limiting block is movably connected in the limiting grooves. The spring assembly is placed between the limiting block and the limiting grooves and fixedly connected thereto.
[0011] Furthermore, the cross-section of the limit block is a right-angled trapezoidal structure and the inclined surface of the limit block is arranged opposite to the inclined surface of the protrusion, the rubber ring is placed on the outside of the lowermost protrusion of the plastic pipe fitting and the inner diameter of the rubber ring is adapted to the outer diameter of the protrusion, and the outer wall of the rubber ring is close to the inner wall of the plastic pipe fitting.
[0012] Furthermore, a placement groove is provided in the connecting member 1 and the rubber ring 2 is placed in the placement groove, a fixing member is sleeved on the plastic pipe member 1 and located on one side of the rubber ring 2, the outer wall of the fixing member is close to the inner side of the plastic pipe member 2 and its side wall is equidistantly provided with five notches adapted to the protrusion along its center, and the protrusion is placed in the notch.
[0013] Due to the adoption of the above technical solution, the beneficial effects of the plastic pipe fitting joint structure of the utility model are as follows:
[0014] 1. Through the setting of the limit assembly, there are four limit blocks in the vertical direction of the pipe fitting 2. When the pipe fitting 1 is pulled apart from the pipe fitting 2, the limit blocks block the protrusions so that they cannot be separated, thus forming a primary limit.
[0015] 2. When the primary limit fails, pipe fitting 1 drives the fixing part outward, hitting rubber ring 2 which is pressed in the placement groove. The grooves of the connecting part and pipe fitting 2 are threadedly connected, so they cannot be detached, forming a secondary limit. BRIEF DESCRIPTION OF THE DRAWINGS
