Improvement of the mandrel structure of the falling head

This creation is a kind of improvement of the mandrel structure of the falling head. It is mainly applied to the water discharge or accumulation structure required in any site, and the mandrel is used to control the smoothness of the falling head when it is closed or opened.

In the case of wastewater treatment in the market today, water pipes are buried under the ground, and in various occasions (home, factory, store, etc.), the pipes for discharging waste water are connected to each other, thereby allowing the indoor wastewater to be discharged. It is discharged to the outside and finally recovered and purified. However, because the outdoor wastewater pipe dredges the wastewater in each room for a long time, there will be a large amount of viruses, bacteria, etc. in the outdoor wastewater pipeline, and even odor and pests, which are generated in the outdoor wastewater pipeline. These substances and tastes are transmitted back to the room along with the direction in which the waste water line is set, thereby affecting the living environment of people in the room.

In order to ensure that the odor and dirt will not be transmitted back to the interior and affect people's living environment, in addition to the treatment of the water treatment plant, the general public will also have a water head to block the odor and other miscellaneous indoors. For the entry of the article, please refer to the Republic of China Patent Publication No. M329646 "Dropping Head Structure", which includes a water drop seat with a water hole, a pipe body disposed on the water drop seat, an action rod reciprocable with respect to the axis of the pipe body, and a cover body locked on the top end of the action rod, the action rod has an action circuit, and the action circuit is formed with a position that can be positioned relative to the tube body A release positioning point and a sealing positioning point, and the cover body has a sealing member capable of relatively closing the water drop seat hole. Through the above design, the user can operate the upper and lower positions of the cover body to relatively fall into the water seat. It has the effect of sealing and releasing, which can facilitate the discharge of sewage, and can effectively prevent mosquitoes or odors in the sewage pipe from crawling or overflowing from the water hole to ensure the sanitation of the home environment.

Although the above-mentioned water drop head structure has provided indoor resistance to odor and entry of mosquitoes, the action bar is driven by the cover body to actuate the return spring in a vertical direction, so that the cover body can close the water drop hole; Conversely, when the return spring is urged against the action rod to drive the cover body to open, the water drop hole is opened to provide drainage effect, so that the return spring is vertically compressed for a long time. The resetting cycle will cause elastic fatigue, and over time, the cover will no longer be able to lift and lower relative to the water trap. therefore. Such a drop head structure must be further improved to suit the public.

In view of the above-mentioned shortcomings, the creator took a lot of time to invest in research related knowledge, and compared various advantages and disadvantages, and carried out research and development of related products, and after many experiments and tests, finally launched a "falling head" The improvement of the mandrel structure is to improve the above-mentioned lack of description to meet the needs of the public.

The main purpose of this creation is to improve the lack of the "falling head structure" listed in the prior art, so as to avoid the occurrence of elastic fatigue caused by prolonged use, and even the subsequent operation cannot be smoothly performed.

In order to achieve the above-mentioned purpose and effect explained in the present creation, the present invention has an improved mandrel structure which is assembled between the falling water seat and the water stopping cap of the falling head, and includes a main shaft main body: the main shaft main body Including a main body and two separate positions The main body section has a receiving chamber in the main body section, and the main inlay hole is arranged on the outer circumference side of the main body section, and the other side of the main body section is corresponding to each main body. The through hole is provided with two corresponding sub-holes, and the main and secondary holes are connected with the accommodating chamber, and further two torsion springs are arranged in the accommodating chamber, and the two ends of the torsion springs are respectively respectively Corresponding to the main and secondary inlays, and partially protruding outside the main and secondary incisions to abut against the water stop cap, and further having a screw hole in the main body section, and another screwing component is locked on the The screw-locking hole; wherein the high-elasticity and rigidity of the two-torsion springs are transmitted to provide a smooth movement of the water-stopping cap relative to the water-seat seat, and the elastic fatigue is not easily generated.

A further technical feature of the present invention is that the outer peripheral sides of the two sets of joints are further provided with external threads for each ring, and are respectively locked with the water trap and the water stop cap.

A further technical feature of the present invention is that each of the torsion springs further includes a torsion section and a bending section extending from each end of the torsion section, each of the bending sections is semicircular, and each of the bending sections is bent The thickness of the fold is smaller than the diameter of the primary and secondary insert holes, and the joint between the torque section and each bend section is formed with a large obtuse angle, so that each bend section is indeed embedded in the primary and secondary inserts.

In combination with the description of the above technical features, the advantage of the present invention is that the water stop cap can be smoothly moved up and down relative to the water drop seat, and the water stop cap is relatively watered for a long time through the arrangement of the torsion springs and the high elasticity thereof. When the seat is displaced up and down, it is not easy to produce elastic fatigue, so that the water cap can be smoothly lifted and lowered to achieve better drainage and sealing purposes. Therefore, this creation can be said to be a kind of practical and progressive creation, which is worthy of promotion by the industry and publicized to the public.
