Abstract
The utility model relates to a connection accessory for a plug-in hot-melt tube, which is characterized in that a liner tube is arranged in a tube; a U-or V-shaped groove is formed between the end of the liner tube and the inner wall of the tube. In use, when the connection accessory for a plug-in hot-melt tube of the utility model is connected with a water pipe, the connection can be carried out along the U-or V-shaped groove. Thus, the connection area between the tube and the connection accessory becomes larger, so that both the outer and the inner walls of the water pipe are partly connected with the accessory. Such a connection mode is firmer and also enhances the security of the water pipe; solves the problem that the joint of the water pipe is likely to leak water and drop off, thereby prolonging the service life of water pipe joints.
Description
Technical field:
The utility model relates to the technical field of hot melt pipe fitting, and specifically a kind of connection fittings that are used for the plug-in type tempreature bulb relate in particular to the connection fittings of plug-in type hot melt water pipe.
Background technique:
At present, when the water pipe on the market connects, often adopt the connection of single side face, though adopt the hot melt Placement, but because it is less to connect area, the influence that expanded with heat and contract with cold by water hammer and current can produce the problem that the water pipe joint leaks, comes off, and brings very big hidden danger for modern finishing.
Summary of the invention:
The purpose of this utility model is to provide a kind of improved connection fittings that are used for the plug-in type tempreature bulb, and it can overcome the some shortcomings of the problem that the water pipe joint leaks easily, comes off in the prior art.
To achieve these goals, the technical solution of the utility model is: a kind of connection fittings that are used for the plug-in type tempreature bulb, it mainly comprises pipe fitting, it is characterized in that: be provided with an internal lining pipe in the pipe fitting, form the groove of U type or V-type between the end of internal lining pipe and the inwall of pipe fitting.
During use, the connection fittings of plug-in type tempreature bulb of the present utility model and water pipe are when being connected, can connect along the groove of U type or V-type, like this between the pipe fitting of water pipe and connection fittings to be connected area bigger, make the inside and outside wall of water pipe that part area and connection fittings all be arranged, such Placement is more firm, has promoted the Security of water pipe, solve the problem that the water pipe joint leaks easily, comes off, prolonged the working life of waterpipe jointing.

Embodiment:
The utility model will be further described below in conjunction with drawings and Examples.
The utility model mainly comprises pipe fitting 1, and its difference with the prior art is: be provided with an internal lining pipe 2 in the pipe fitting, form the groove 3 of U type or V-type between the end of internal lining pipe and the inwall of pipe fitting.The end of internal lining pipe is apart from the end 0.2-2cm of pipe fitting.The diameter of internal lining pipe is the 1/3-4/5 of pipe fitting diameter.The groove depth of U type or V-type is 0.2-1.5cm.
In force, the connection fittings of plug-in type tempreature bulb of the present utility model are generally single tube joint, elbow and tee union, form U type groove between the end of the internal lining pipe in the pipe fitting and the inwall of pipe fitting.When water pipe 4 links to each other with the connection fittings of plug-in type tempreature bulb, between the inside and outside wall of water pipe and the U type groove by being connected behind the hot melt, being connected between the connection fittings of water pipe and plug-in type tempreature bulb is exactly two-sided connection like this, more firm, solved the defective that water pipe leaks easily, comes off in the prior art.
Form V-groove between the end of the internal lining pipe in the pipe fitting of the present utility model and the inwall of pipe fitting.The end of internal lining pipe is apart from the end 1.5cm of pipe fitting.The diameter of internal lining pipe is 2/3 of a pipe fitting diameter, and the groove depth of V-type is 0.5cm.When water pipe links to each other with the connection fittings of plug-in type tempreature bulb, between the inside and outside wall of water pipe and the V-groove by being connected behind the hot melt, being connected between the connection fittings of water pipe and plug-in type tempreature bulb is exactly two-sided connection like this, and be more firm, promoted the Security that water pipe connects.
