Pipe joint structure

The present invention relates to a pipe joint structure, in particular to a pipe joint design with simple and stable assembly, which can maintain the tensile stress, pressure resistance, shock resistance, cold resistance, thermal expansion and contraction of the pipeline joint; The achievement of the effect, in addition to the effective use of the interaction generated by the combination of components, and then derived multiple effects, in particular - the joint between the connector, the pipe, the screw and the leak-proof rubber ring In addition, it can simultaneously provide the insurance mechanism for preventing and taking off the pipe, and can achieve the double performance of locking and merging and leakproof; therefore, in addition to the pipe piping engineering, in addition to effectively increasing the pipe speed with a simple structure, The combination of locking and anti-leakage aprons can strengthen the tensile stress between the nozzle and the nozzle, and achieve the dual practical functions of shockproof and leakproof.

Check; the liquid conveying pipeline is mainly for matching straight, multi-directional or corner piping, or corner piping, and the pipeline and the pipeline are connected to each other, relying on the pipe joint assembly; of course, the function of the pipe joint, in addition to the connection In addition to piping, the leakage function is also a basic requirement; in the current demand, it can be exchanged at the lowest cost, which can withstand the strong tensile stress, internal pressure resistance, shock resistance and cold resistance, heat, etc. The main issue that needs to be solved urgently.

Based on the above, it is not easy to achieve the above four requirements and requirements at the same time; in the case of conventional pipe joints, the majority is limited to the internal pressure reaching a certain strength, and the pipe joint The lock will not fall off, let alone the insurance mechanism that may be out of control. As for the leak prevention effect, it is often lost in a few years; this kind of surface effort will cause quite a lot of public dangers and inconvenience to life. Afterwards, it was not worth the candle.

However, the conventional users are fixed and leak-proof, and the main body is made of a single element of a leak-proof rubber ring. However, the conventional aprons can withstand the effects of fixing and stopping leakage, and can only reach a certain one. The degree of stress is only the result. Therefore, the use of the apron and the tight structure of the body are insufficient. The more worrying is the service life, often in a bad environment, such as: seismicity. The vibration, the expansion of the temperature difference and the shrinkage, the increase of the instantaneous internal pressure, etc., all cause rapid fatigue and damage of the internal components, vibrations, and leakage, so most of the piping engineering life, It is simply impossible to achieve the desired goal.

In order to fully understand the structure and function of the pipe joint, the 第四 cooperates with the fourth figure; the figure is exemplified by a pipe joint A1 assembled to a three-way joint A2; the three-way joint A2 has an upper screw seat A21 , a cap A3 lock can be engaged; when the connector A1 is inserted into the inner hole of the upper end screw A21, a leak-stop rubber ring A4 is assembled between the top edges of the two to achieve basic leakage prevention performance; The leakage apron A4 is located outside the connector A1, and a metal gasket A5 is additionally sleeved. After the metal gasket A5 is locked and pressed by the cap A4, the lower leakage rubber ring A4 can be pressed to force it to The deformation mode achieves the purpose of fixing the pipe (A1).

After understanding the structure of the conventional pipe joints, it is not difficult to know that many components are used by the pipe joint structure of the learner, which greatly increases the construction procedure and cost, and the metal washer A5 and the leak-stop rubber ring A4 are The combination of the whole joint plays a major role, but after the tensile test of the pipeline, the tensile strength between the two joints appears to be rather weak and insufficient; the main problem lies in the fact that the fixed and the leak are all stopped by one stop. Apron A4 only; therefore, when the apron A4 deformation is not enough or the leaking apron A4 is fitted, it will damage the apron A4 without any knowledge; especially--- Stop leaking point, go to As the pulling force increases, the entire taken-over A1 is not pulled out or a large displacement is caused. These phenomena are the most fatal injuries in the pipe fitting, and leakage, pipe-out and pipe breaking often occur; therefore, The pipe joints of the learners simply did not meet the conditions and objectives required for basic piping.

Based on the aforementioned lack of the learner, the present invention provides a pipe joint structure, which is mainly used for locking a screw by a keyhole, and is locked by a screw to a position where the adjacent end of the pipe is connected, so as to be completely prevented. The problem of disconnection may occur in the takeover, and the advantage of preventing the out-of-pipe insurance mechanism is obtained.

The design of the case is mainly based on the screw fitting and the retaining washer can be locked to the pipe joint to exert its ability to lock and retreat; in particular, when the screw is matched with a retaining washer, it is completely locked to the pipette. When the positioning groove is located, the taken pipe is not disturbed by the external shock force and the pulling stress, and the displacement damage occurs; in other words, the functional effect of the case can achieve the aforementioned requirements. It has five major requirements: the system for removing the pipe, the strong tensile stress, the internal pressure resistance, the shock resistance, and the cold resistance and heat resistance.

The structure of the present invention mainly consists of: a take-over, a plurality of screw parts, two leak-proof rubber rings and a pipe joint component, the pipe joint is provided with at least one lock hole with respect to the position of the converging wall of the pipe, and the screw pieces are respectively locked. Merging through the keyhole, so that the screw member and a backing washer are locked to the adjacent end positions of the positioning groove of the pipe to be taken, and the problem of the pipe removal may occur to prevent the pipe from being taken up; and then two leakproof rubber rings are used. It is forced to take over the outer edge wall and force the glue groove of the pipe joint to achieve the three-effects of tightness, leakage prevention and coercion; therefore, when the pipe is in a slight vibration or thermal expansion and contraction ...etc., when the adverse external environment is affected, both the takeover and the leak-proof rubber ring will inevitably maintain the tight leak-stop effect, and then derive the practicality of preventing and controlling the pipe, resisting the high pressure, the vibration resistance, the cold resistance, the heat temperature difference, etc. Efficacy.

In summary, the purpose and structure of the case are as described above. When the merits of the case have been highlighted, the expected effectiveness of the case is recognized by us. As for the other purposes, features and effects of the case, it will be explained in detail with the following examples and drawings. Make the review more clear.

Figure 4: Schematic diagram of the overall cross-sectional structure of a conventional pipe joint.

First, please refer to the first, second and third figures. The overall structure of the present case includes at least one taken over 1, a plurality of screws 2, a backing washer 21, at least two leakproof rubber rings 3 and a pipe joint 4.

The pipe 1 is provided with at least two end heads 10, and can be formed into a rounded shape at the edge of the end 10, which is easy to be introduced in the fitting, and can also eliminate the edge edge state of the end 10, thereby effectively protecting the built-in pipe. The two leak-proof rubber rings 3 are not cut.

The pipe joint 4 includes at least two pipe ports 40, and a converging and urging wall 41 is disposed on the inner edge of the pipe port 40 end. The urging wall 41 adopts a tapered and convergent structure design, so that the urging wall 41 is gradually formed. The inside of the pipe joint 4 is provided with at least two glue grooves 42 at a position relative to the converging and urging wall 41; and the outer portion of the pipe joint 4 is provided with at least one key hole at a position relative to the converging and urging wall 41 provided. 43. The keyhole 43 extends through the converging wall 41.

When the pipe joint 1 is engaged with the pipe joint 4, at least two leakage preventing rubber rings 3 may be sleeved on the outside of the pipe joint 1; when the pipe joint 1 is placed in the converging wall 41 of the pipe joint 4 When the screw member 2 is engaged with the retaining washer 21, it can be respectively engaged with the locking hole 43 and penetrates through the converging and urging wall 41, so as to be locked to the adjacent end of the positioning slot 11 of the connected tube 1 by the screw member 2. The position of the head 10 can achieve the problem that the pipe can be removed from the pipe 1; in addition, when the leakage preventing rubber ring 3 is fitted to the outer wall of the pipe 1 to be connected, the glue groove 42 provided in the pipe joint 4 can be disposed inside. , to implement the ability to resist leakage, to achieve the effect of tight air and stop leakage.

It is necessary to emphasize the two leakage preventing rubber rings 3, and the optimum configuration size is such that the inner diameter of the leakage preventing rubber ring 3 is smaller than the outer diameter of the pipe 1 to be taken; after the configuration, the leakage preventing rubber ring 3 will still be glued by the rubber ring 3 The body has a small compression margin and is forced to be taken over by the pipe 1; when the pipe 1 is subjected to high-intensity vibration, thermal expansion and contraction, excessive tensile stress or instantaneous supercharging, etc., the abnormal state and the external environment are affected. Both the take-over 1 and the leak-proof apron 3 are inevitably able to maintain a tight leak-stop effect, and thus derive practical effects such as prevention of pipe-out, high-pressure resistance, vibration resistance, cold resistance, and thermal temperature difference.

In addition, the overall structure of the case is more simplified, which will greatly reduce the construction procedures and costs, have absolute market competitive advantages, and can also become the mainstream of the embedded pipeline configuration in the construction industry.

To sum up, in this case, regardless of the use of performance, efficiency, advancement and novelty, the case is of course practical and practical, from the perspectives of function, effectiveness, progress and novelty. The elements of progress are in line with the functional enhancements and practical elements emphasized by the new patent law. I would like to ask your review committee to give the protection of this creation as soon as possible after careful examination.
