Description

Quick-connect structure of fluid shock absorber

The present invention relates to a quick connector structure, and in particular to a quick connector structure of a fluid shock absorber, which can provide a water tank, a pipeline box, and a connector structure that can quickly connect a valve body and does not loosen.

For example, the pipes of water tanks, faucets, or complex pipes used to collect wastewater will gather the aforementioned pipes and connect them to a pipe box to supply indoor cold water, hot water or warm water according to demand, or guide the wastewater into the sewage sewer.

The aforementioned pipeline box is equipped with a pipeline, and the pipeline has a connecting valve to open and close the pipeline connection. The connecting valve can be connected to the faucet pipeline or the waste water pipeline, and corresponding actions are performed through the pipeline.

The pipeline box is mainly used to facilitate the management of pipelines and lines to avoid malfunctions caused by misoperation. Furthermore, a mounting hole will be drilled at the connection between the pipeline box and the connecting valve, and the connecting valve will be installed and then screwed with a nut to achieve the effect of fixing the connecting valve to the pipeline box and reducing fluid vibration.

However, when using a nut to thread a connection, the nut may gradually loosen due to slight vibrations caused by the fluid passing through the pipeline or the connecting valve.

The present invention provides a quick connector structure for a fluid shock absorber, the main purpose of which is to simplify the assembly process of a connecting valve and a pipeline box, and to adopt a one-way rotating positioning element to prevent the connecting valve and the pipeline from being separated due to vibration generated by the fluid.

Therefore, the structure of the present invention is applied to a pipeline box, which provides a connecting valve assembly for at least one pipeline, and the pipeline box has an assembly hole for providing the connecting valve assembly;

The connecting valve is equipped with a fixed joint, which has a barrel, a plurality of positioning points are formed on the surface of the barrel, and a U-shaped slot is provided at the lower end of the positioning points, and a slightly raised spring portion is provided in the slot;

The assembly hole of the pipeline box is provided with a symmetrically arranged slot corresponding to the positioning points;

The connecting valve is assembled in the assembly hole of the pipeline box, and the positioning point of the barrel is inserted into the slots to fix the position of the connecting valve;

A positioning ring is provided on the outer side of the pipeline box, and a cross-arranged groove is provided on the central inner side of the positioning ring, and a U-shaped positioning part is provided on two sets of opposite grooves, and the aforementioned positioning part is in the same direction as the grooves;

The positioning ring is fitted on the fixed joint, and the positioning ring is rotated so that the positioning parts on the grooves are engaged with the elastic parts, so that the connecting valve is firmly fixed on the pipeline box; when maintenance is required, the positioning ring is rotated along the opening direction of the positioning part so that the elastic part is separated from the positioning part, and the positioning ring can be separated from the fixed joint.

In an embodiment of the present invention, a hexagonal head is provided on the top of the barrel.

In an embodiment of the present invention, the assembly hole is further provided with notches corresponding to the elastic parts.

In an embodiment of the present invention, the outer side of the positioning ring has a symmetrically arranged pull portion.

Through the above description, the features and effects of the present invention are briefly described as follows:

1. The present invention only requires fixing the joint on the connecting valve sleeve, then inserting the connecting valve into the pipeline box, and finally fitting the positioning ring onto the lower end of the fixed joint to complete the assembly, and the installation can be done by hand.

2. The spring clip is used to lock the positioning part, eliminating the problem of threaded joints being easily loosened. The slot used to receive the spring is in the same direction as the positioning part, achieving a one-way rotation function and preventing the positioning ring from being separated from the connecting valve.

As shown in FIG. 1 to FIG. 3 , the quick connector structure of the fluid shock absorber of the present invention is applied to a pipeline box 10 , which provides a connecting valve 30 assembly for a pipeline 20 , and the pipeline box 10 has an assembly hole 11 for providing the connecting valve 30 assembly.

As shown in FIGS. 1 to 3 , the connecting valve 30 is installed with a fixed joint 40, which has a barrel 41 with a hexagonal head 42 at the top of the barrel 41, a plurality of positioning points 43 are formed on the surface of the barrel 41, and a U-shaped slot 44 is provided at the lower end of the positioning points 43, and a slightly raised spring portion 45 is provided in the slot 44.

As shown in FIG. 2 and FIG. 3 , the assembly hole 11 of the pipeline box 10 is symmetrically arranged with the slots 12 corresponding to the positioning points 43 . In addition, in order to facilitate the elastic part 45 of the fixed joint 40 to quickly pass through the assembly hole 11 , the assembly hole 11 is also provided with notches 13 corresponding to the elastic parts 45 .

As shown in FIGS. 2 and 3 , a positioning ring 50 is provided on the outer side of the pipeline box 10, and a cross-arranged groove 51 is provided on the central inner side of the positioning ring 50, and a U-shaped positioning portion 52 is provided in two sets of opposite grooves 51, and the aforementioned positioning portion 52 is in the same direction as the slots 44. In addition, the outer side of the positioning ring 50 has a symmetrically arranged pull portion 53.

The above is an introduction to the structure of the present invention, followed by an introduction to the assembly method of the present invention, as well as the effects and advantages that can be obtained.

As shown in FIGS. 4 and 5 , the positioning ring 50 is fitted on the fixed joint 40 . As shown in FIG. 6 , the positioning ring 50 is rotated so that the positioning portions 52 of the grooves 51 are engaged with the spring portions 45 , so that the connecting valve 30 is stably fixed on the pipeline box 10 . When maintenance is required, the positioning ring 50 can be rotated by holding the pull portion 53 and rotating along the opening direction of the positioning portion 52 so that the spring portion 45 is separated from the positioning portion 52 , and the positioning ring 50 can be separated from the fixed joint 40 .

2. The present invention only needs to put the fixed joint 40 on the connecting valve 30, then insert the connecting valve 30 into the pipeline box 10, and finally put the positioning ring 50 on the lower end of the fixed joint 40 to complete the assembly. It can be installed by hand without tools, which is very convenient.

3. The spring 45 is snapped into the positioning portion 52 to avoid the problem of threaded connection being easily loosened. In addition, the slot 44 for receiving the spring 45 is in the same direction as the positioning portion to achieve a one-way rotation function, which has the effect of preventing the positioning ring 50 from being separated from the connecting valve 30.

In summary, the structure of this invention has never been seen in any books or periodicals or used publicly, and it truly meets the requirements for invention patent application. We sincerely request the Bureau to examine it and approve the patent as soon as possible. I would be very grateful.
