DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Referring to Figures 1 to 3 A via hole mounting assembly as shown, which includes a base 10, a flat head screw, a locking piece 30 and a guide rod 40. The flat head screw and the guide rod 40 both pass through the base 10 and are located on the same side of the base 10. Specifically, a first through hole 12 is provided on the base 10, and a limiting protrusion 13 is arranged above the first through hole 12. One end of the flat head screw passes through the first through hole 12 and its flat head is restricted between the upper end of the first through hole 12 and the limiting protrusion 13 to ensure that the flat head screw cannot be easily separated from the base 10. The guide rod 40 is fixedly connected to the base 10. The locking piece 30 is hinged at both ends of the core shaft 31. A threaded hole 32 for cooperating with the flat head screw is further provided on the side surface of the core shaft 31. After one end of the flat head screw passes through the threaded hole 32, a limiting cap 21 is arranged at its end. The limiting cap 21 can be sleeved or welded to the end of the flat head screw after assembly to ensure that the locking piece 30 / core shaft 31 cannot be separated from the flat head screw. It can be seen that in the present utility model, the base 10 and the locking piece 30 / core shaft 31 are respectively arranged at both ends of the flat head screw and cannot be separated from the flat head screw. When the user receives the goods, it is an assembled product and can be directly used, which is convenient and fast. A second through hole 33 is provided on the side surface of the core shaft 31. One end of the guide rod 40 passes through the second through hole 33. Two spaced limiting bars are arranged on the locking piece 30. The two limiting bars are spaced. When the locking piece 30 can freely rotate relative to the core shaft 31 until the limiting bars abut against the guide rod 40, the locking piece 30 is in a vertical or horizontal placement posture. During packaging and transportation, the locking piece 30 can be placed in a vertical posture to avoid the problem that the locking piece 30 protrudes relative to the base 10 and causes difficulty in packaging due to excessive volume. During use, the locking piece 30 can freely rotate to its horizontal placement posture, and the water pipe can pass through between the two limiting bars of the locking piece 30 and pass out from the base 10.

[0021] In some possible embodiments, the aperture of the first through hole 12 is larger than the rod diameter of the flat head bolt 20, or the first through hole 12 is elliptical. The purpose is to ensure that when the flat head bolt 20 is blocked by the limiting protrusion 13, the flat head bolt 20 can penetrate into the first through hole 12 only after tilting a certain angle relative to the first through hole 12, and after passing through the first through hole 12, the flat head bolt 20 is blocked by the limiting protrusion 13 and cannot be easily taken out from the first through hole 12, so as to avoid the risk that the flat head screw is separated from the base 10 due to shaking during packaging and transportation.

[0022] In some possible embodiments, the inner ring protrusion of the base 10 has a boss 11 for forming the first through hole 12. The protrusion shape and size of the boss 11 are based on not affecting the water pipe passing through the inner ring of the base 10. The limiting protrusion 13 and the boss 11 can be obtained by die-casting as one piece with the base 10, and the limiting protrusion 13 is located above the boss 11.

[0023] In some possible embodiments, the hinge point between the locking plate 30 and the core shaft 31 is located at a non-middle position of the locking plate 30 and close to one end of the locking plate 30. The two limit bars are divided into a first bar 34 and a second bar 35. The first bar 34 is close to the hinge point between the locking plate 30 and the core shaft 31, and the second bar 35 is located at the end of the locking plate 30 away from the hinge point. The locking plate 30 can rely on the gravity of the second bar 35 to rotate to a horizontal position relative to the core shaft 31, that is, the locking plate 30 cannot maintain balance when it is rotated to a non-completely vertical position relative to the core shaft 31. It is affected by the gravity of itself / the second bar 35 and rotates to a horizontal position autonomously. Even if the locking plate 30 is rotated to a completely vertical position during installation, only a slight shake is required to make the locking plate 30 rotate autonomously to a horizontal position to facilitate the water pipe to pass through from bottom to top.

[0024] In some possible embodiments, there are two guide rods 40 and they are arranged on opposite sides of the flat-head screw. One end of the guide rod 40 is welded to the base 10 or fixed by interference fit of the hole axis. In this embodiment, the guide rod 40 has two functions. One is to ensure that when the flat-head screw drives the core shaft 31 / locking plate 30 to move up and down, the core shaft 31 / locking plate 30 will not rotate and cause the locking plate 30 to be inaccurately positioned. The second is to cooperate with the two limit stop bars to limit the locking plate 30 to reciprocate between the vertical position and the horizontal position.

[0025] In some possible embodiments, a plurality of positioning ring pieces 14 are provided at the lower end of the base 10, and the plurality of positioning ring pieces 14 are evenly distributed along the circumference, so as to facilitate the accurate installation of the base 10 on the installation hole of the table top. Furthermore, a sealing ring 15 is provided at the lower end of the base 10 to seal the gap between the base 10 and the table top.

[0026] The above is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
