detailed description

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to Figures 1 and 2, a quick-fit joint structure consists of a water inlet valve 1, a fixing nut 2, a guide member 3, a rotary buckle 4, a torsion spring 5, and a base 6.

Wherein, the lower part of the base 6 is provided with a threaded joint 61, and the upper half is provided with a cylindrical body 62, wherein the cylindrical body 62 is provided with an external thread 3. The wall of the cylindrical body 62 is provided with an opening groove 64 communicating with the inside and the outside from the top end. In the present embodiment, the number of the opening grooves 64 is two and arranged symmetrically. Two positioning grooves 65 are symmetrically provided on the inner wall of the cylindrical wall 62. The two positioning grooves 65 and the opening grooves 64 are spaced apart by 90 degrees, respectively.

Referring to Fig. 4, the torsion spring 5 is provided with two chucks 51 which are respectively located in the two open slots 64 when installed. In other embodiments, the two chucks may also be located in the same open slot 64.

The guiding member 3 has a cylindrical shape, and the outer wall is symmetrically disposed with two positioning posts 31 adjacent to the upper end, and the inner wall is provided with four upper guiding grooves 32 which are spaced apart from each other by 90 degrees. The positioning post 31 is configured to cooperate with the positioning groove 65 of the base 6.

Referring to FIG. 4, the rotary buckle 4 is cylindrical, and a push button 41 is disposed on the upper end of the outer wall. A torsion spring positioning groove 42 is disposed between the lower end of the knob 41 and the cylinder wall, and four lower guide grooves 43 are disposed on the inner side of the cylinder wall. The four lower guide grooves 43 are arranged at intervals of 90 degrees. A guiding block 44 is disposed to the right of the left side wall of each lower guiding groove, wherein the upper surface of the guiding block 44 is a guiding inclined surface 45, and the lower surface of the guiding block 44 is a limiting inclined surface 49, which is defined by the right side of the convex block Tilting to the upper left, a limit portion is formed at an angle between the limit slope 49 and the lower guide groove 43, and the rotation buckle can be prevented from excessively rotating. In other embodiments, the position-only ramp 49 can also form a limit portion because the bottom surface itself can prevent the guide limit rib on the plug from moving upward. The limit slope 49 can also be a plane. In other embodiments, the limiting portion may also be disposed on the base.

At the upper end of each lower guiding groove 43, a groove 46 is provided at the wall of the cylinder, and each groove 46 is provided with a resilient column 47, and a resilient rib 48 is provided on a side of each of the elastic columns 47 facing the inside of the wall.

Referring to Fig. 5, at least one guide limiting rib 13 is provided on the outer circumference of the inlet pipe (or joint) of the inlet valve 1, and in the present embodiment, four are evenly arranged along the circumference. The top end of each of the guide limiting ribs 13 is an inclined surface 14 which cooperates with the limiting inclined surface 49 of the rotary buckle 4.

In order to make the water inlet valve easy to disassemble, the present invention provides at least one disassembly guide rib 11 on the upper surface of the guide limiting rib 13, and in this embodiment, four pieces are evenly arranged along the circumference. The lower half of each of the detaching guide ribs 11 is provided with a resilient rib guide groove 12, the function of which will be described in detail later.

Referring to Figures 1, 5 and 6, the assembly of the present invention is as follows: first, the torsion spring 5 is inserted into the rotary buckle 4 from bottom to top, and enters the torsion spring positioning groove 42, and then the rotary buckle 4 is loaded into the base from top to bottom. In the cylindrical body 62 of the sixth embodiment, the knob 41 of the rotary buckle 4 is located in an opening groove 64 of the base, and the two chucks 51 of the spring are respectively connected to the base 6 and the rotary buckle 4 in the two opening slots 64. And one of the chucks acts on the side of the dial 41 to force it against a side wall of the opening groove 64. In other embodiments, it is also possible that the two chucks are simultaneously located in the same opening groove 64, one of which is located on the side wall of the opening groove 64, and the other chuck acts on the side of the dial 41 to force it to interfere with the opening groove 64. One side wall, so that only one open slot is required.

After that, the positioning post 31 of the guiding member 3 is aligned with the positioning groove 65 of the base, and the guiding member 3 is fitted into the base. Within 6. Due to the limiting action of the positioning post 31 and the positioning groove 65, the guiding member 3 is positioned in the upper end of the base, and a gap can be left between the upper end of the rotating buckle 4 and the lower end of the guiding member 3 according to design requirements, for example, 1- 2 mm, such that the rotary buckle 4 is not subjected to the pressure of the guide member 3 and causes difficulty in rotation. Then, the fixing nut 2 is rotatably attached to the upper end of the base 6, so that the guiding member 3 does not move upward. After the above components are mounted to the base 6, the base 6 is then secured to the toilet tank.

The invention is used as follows: the guide limiting rib 13 on the inlet pipe of the inlet valve is aligned with the upper guiding groove 32 of the guiding member 3, and the guiding limiting rib 13 is in contact with the guiding inclined surface 45 of the rotating buckle 4 through the guiding groove 32. . Under the pressing force, the rotary buckle 4 is rotated by an angle against the force of the torsion spring 5, so that the guide limiting rib 13 passes through the lower guiding groove 43 and passes over the convex block 44 downward. 4Reset, rotating in the opposite direction, the limiting slope 49 at the bottom of the protrusion 44 and the inclined surface of the guiding limiting rib 13 cooperate with the limit. That is, the quick installation process is completed. In other embodiments, the bottom of the bump 44 may not be a slope. The guide limiting ribs 13 may also have other shapes, for example, all of them are flat, but the two inclined surfaces are preferably matched to prevent the rotating buckle 4 from being in the water. Reverse rotation under pressure.

When disassembling, the dial 41 of the rotary buckle 4 is toggled to rotate against the force of the torsion spring, so that the limiting slope 49 at the bottom of the protrusion 44 of the rotary buckle 4 is disengaged from the inclined surface of the guiding limit rib 13, and the lower guiding slot The right side portion of the 43 is rotated to the same vertical plane of the guide limit ribs 13. The elastic rib 48 to the rotary buckle 4 is rotated into the elastic rib guide groove 12 of the detachment guide rib 11 of the water inlet valve, so that the reset action of the torsion spring can be overcome, and it is no longer necessary to press the dial button. At this time, the inlet valve can be pulled out directly. The elastic rib 48 and the guide rib 11 are disengaged, and the rotary buckle 4 is reset. Can be installed next time.

The above is only one specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. In another embodiment, the guide member 3 may be omitted, and the rotation buckle may be directly limited by a nut; There is no guiding member 3 and fixing nut 2, and the rotating buckle is directly fixed on the base by an elastic block on the wall, and an elastic block limiting hole is arranged on the base, and can be rotated at a certain angle; or the rotating buckle has a larger diameter than the base. The sleeve is connected to the outside of the base 6 and various deformation modes. Any insubstantial modification of the invention by this concept is intended to be an infringement of the scope of the invention.
