Description

Technical Field

[0001] The utility model relates to the relevant field of water pipe joints, in particular to a split water pipe joint which prevents an inner pipe from being punctured. Background Art

[0002] A joint is a component used to connect water pipes. According to the way they are used, water pipe joints can be divided into: external threaded end-connected water pipe joints, ferrule-type water pipe joints, and self-fixing water pipe joints. External threaded end-connected water pipe joints are die-cast with zinc alloy materials, and the surface is galvanized, frosted, or chrome-plated; they have a compact structure, no pores, and high strength.

[0003] When the joint in the prior art is connected to the water pipe, a metal sheet anchoring method is usually adopted. Although a tight connection between the joint and the water pipe can be achieved, the installation is inconvenient. During the anchoring process of the metal sheet, the water pipe is easily punctured, causing unnecessary economic losses. In addition, the joint and the water pipe are integrally connected, and it is also difficult to disassemble when the water pipe needs to be replaced. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a split water pipe joint with an anti-puncture inner tube, comprising a connecting nut, a threaded head, a protective sleeve, a fixing tube and a fixing tube, wherein the left side of the connecting nut is connected to a threaded head, the outer side of the threaded head is connected to a protective sleeve, the middle end of the left side of the threaded head is connected to a fixing tube, and the fixing tube is inserted into the threaded head and the fixing tube.

[0006] Preferably, a slope is provided on the left side of the protective sleeve, and the surfaces of the middle end and the right end of the protective sleeve are both frosted.

[0007] Preferably, a containing cavity is provided inside the protective sleeve, and an internal thread is provided on the right inner wall of the protective sleeve.

[0008] Preferably, a connecting cavity is provided inside the fixing cylinder, and a clamping groove is provided on the right side inside the threaded head, and the clamping groove inside the threaded head is communicated with the connecting cavity inside the fixing cylinder.

[0009] Preferably, a circle of blocks extending outward is provided at the right end of the fixed tube, and a slope is provided in the middle of the fixed tube.

[0010] Preferably, the inner wall of the connecting nut is provided with an internal thread, and the surface of the connecting nut is frosted.

[0011] Preferably, the left and right ends of the protective sleeve are hollowed out, and the inner wall of the protective sleeve is smooth and free of burrs.

[0012] Preferably, a through hole is provided at the middle end of the fixing tube.

[0013] Beneficial effects of the utility model:

[0014] The utility model is provided with a fixing pipe, so that the water pipe can be first extended into the connecting cavity in the fixing cylinder, and then the fixing pipe is inserted into the water pipe after passing through the connecting nut. The fixing pipe can open the two sides of the water pipe so that the outer wall of the water pipe is tightly attached to the fixing cylinder. The water pipe can be fixed by the fixing cylinder and the fixing pipe, and the connection can be achieved without the use of anchor pressure. The disassembly and assembly are convenient. The protective sleeve and the fixing cylinder can also protect the water pipe connection to prevent the water pipe from being damaged by sharp objects during use. The utility model is highly practical. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to further explain the technical solution of the present utility model, it is described in detail through specific embodiments below.

[0021] See also Figure 1-4 The utility model provides a split water pipe joint for preventing puncture of the inner pipe, comprising a connecting nut 1, a threaded head 2, a protective sleeve 3, a fixing tube 4 and a fixing tube 5. The connecting nut 1 is integrally formed with a threaded head 2 on the left side, and a accommodating cavity is arranged inside the protective sleeve 3. The left and right ends of the protective sleeve 3 are hollowed out, and the inner wall of the protective sleeve 3 is smooth and has no burrs, which is convenient for inserting the water pipe, and the inner right wall of the protective sleeve 3 is provided with an internal thread, and the threaded head 2 is threadedly matched with the protective sleeve 3 through the outer thread, and a fixing tube 4 is integrally formed with the left middle end of the threaded head 2, and a connecting cavity is arranged inside the fixing tube 4, and a card groove is arranged on the right side of the threaded head 2, and the card groove inside the threaded head 2 is connected with the connecting cavity inside the fixing tube 4, and a circle of card blocks extending outwards are integrally formed on the right end of the fixing tube 5, and a bevel is arranged in the middle part of the fixing tube 5, and the left end of the fixing tube 5 penetrates the threaded head 2 and is inserted into the connecting cavity inside the fixing tube 4 to realize the positioning of the water pipe, and the fixing tube 5 is engaged with the card groove inside the threaded head 2 through the card block to achieve the limit of the fixing tube 5.

[0022] Among them, a slope is provided on the left side of the protective sleeve 3, and the surfaces of the middle end and the right end of the protective sleeve 3 are both frosted, so that the user can grasp the protective sleeve 3 conveniently.

[0023] The inner wall of the connecting nut 1 is machined with an internal thread, and the surface of the connecting nut 1 is frosted, so that the user can easily rotate the connecting nut 1.

[0024] A through hole is provided at the middle end of the fixed pipe 5 to enable water to flow.

[0025] Here’s how it works:

[0026] First, the user passes the water pipe through the accommodating cavity of the protective sleeve 3, and then inserts the water pipe into the connecting cavity in the fixed tube 4, then inserts the left end of the fixed tube 5 from the middle end of the connecting nut 1, and inserts the left end of the fixed tube 5 into the water pipe. Since the middle end of the fixed tube 5 has a slope, the fixed tube 5 can open the water pipe so that the outer side of the water pipe is close to the inner wall of the fixed tube 4. The water pipe can be fixed by the fixed tube 4 and the fixed tube 5, which is easy to install. Then the protective sleeve 3 can be rotated so that the protective sleeve 3 is connected to the threaded head 2 through the internal thread. The water pipe connection can be protected by the protective sleeve 3 and the fixed tube 4 to prevent the water pipe from being punctured by sharp objects. Finally, it can be connected to the equipment joint through the connecting nut 1, and when the equipment joint is screwed into the connecting nut 1, it can be against the fixed tube 5, and the water flow in the water pipe can flow into the equipment joint through the through hole at the middle end of the fixed tube 5 to realize water supply.
