Description

Improvement of joint structure of telescopic water pipe

This creation relates to the joint structure of the water pipe joint, and in particular to the joint structure improvement of a water pipe capable of extending and contracting.

At present, there are a variety of water pipes with elastic expansion and extension, which are widely loved by consumers. They can be applied to the environment such as courtyards and homes. When used, they naturally extend the length and greatly increase the convenience. For the assembly structure of the water pipe, as shown in the Patent No. M444454 of the Republic of China, it mainly comprises an elastic inner tube, a braided outer tube and a joint member, and the elastic inner tube and the braided outer tube are sleeved. In the pipe plug portion of the joint member, the elastic collar and the joint ring body are used to fix the tension between the elastic inner tube and the braided outer tube, thereby achieving the purpose of joining the tube body and the joint member, and finally It can be used by connecting the joint element to the water outlet (usually a faucet).

However, the current joint structure is mostly a conventional water pipe fixing method, in which the water pipe is sleeved at a predetermined position and then clamped and fixed by a tightening member, and when the telescopic water pipe of the double pipe body is applied, the pipe body is socketed. The space is limited. When assembling, there are often operational difficulties. In particular, the fixing of the outer tube is easily affected by the inner tube, and the unfamiliar user is prone to loosening due to the fixed inaccuracy. In addition, in the process of repeated disassembly and assembly, it is also easy to cause things. The wear and tear of the parts and other problems cause the user to be troubled in use.

In view of this, the creators of this novel are committed to simplifying the direction of the assembly as the starting point, to create and improve, and through continuous efforts, the creation of this creation.

The main purpose of this creation is to simplify the assembly and enhance the convenience by fixing the inner tube and the outer lining in the joint seat and the outer side respectively.

Another purpose of this creation is to use a specific structure fixed by the partition, which can greatly reduce the error rate of the general user when connected, and reduce the possibility of loosening of the water pipe during use.

In order to achieve the above-mentioned effects and purposes, the expansion joint structure of the present invention is improved, and the main technical means adopted is a joint seat, a pipe plug, an inner pipe, a joint, an outer liner and a clamp kit; The connecting seat is provided with a constant hole, and the through hole is provided with a retracting engaging portion; the plugging member is disposed in the through hole and can be engaged with the engaging portion; the inner tube is relatively elastic The tube can be extended and extended, and the inner tube can be inserted into the through hole and sleeved to the tube plug, so that the inner tube is clamped between the tube plug and the engaging portion, and the tube plug is provided The through hole can be connected to the inner tube; the adapter is coupled to the connecting seat, and is provided with an extending portion that can extend into the through hole to abut the top of the pipe plug, and the through joint can be connected through The through hole is sleeved outside the inner tube and is wrinkled and can be expanded or contracted with the inner tube; the clip kit is coupled under the joint to clamp the outer liner to the clip Between the kit and the dock.

Therefore, when the user assembles, the inner tube only needs to be inserted into the through hole and sleeved on the pipe plug member, and the internal structure and the adapter can be clamped to automatically form the inner tube to form a stable fixing. There is no possibility of loosening; when fixing the outer lining, it is not easily affected and causes operation. The mistakes made it easy for the average user to complete the assembly.

Preferably, the plug member comprises a barrel that can be sleeved by the inner tube and a convex portion that protrudes outwardly from the top end of the barrel.

Preferably, the barrel body is further provided with a convex card abutting portion in a partial section, whereby the engaging portion of the card abutting portion and the connecting seat can be used to form a better clamping effect.

Preferably, the connecting seat is provided with an upper connecting portion and a lower connecting portion respectively at the upper and lower positions, the upper connecting portion is for coupling with one of the joints of the adapter, and the lower connecting portion is for combining the clamping kit A joint.

Preferably, the adapter is further provided with a waterproof ring outside the extension.

Preferably, the connecting seat extends below the lower connecting portion with a clamping portion, and the clamping sleeve is also provided with a retracting clamping portion at an opposite position for clamping the outer liner therebetween. .

Preferably, the outer liner and the inner tube are further provided with an anti-friction layer, and the anti-friction layer is sandwiched between the clip and the joint together with the outer liner.

Preferably, the upper connecting portion and the joint portion, the lower connecting portion and the joint portion are screwed together by internal and external threads.
