Detailed Description

In order to further explain the technical solution of the present invention, the present invention is explained in detail by the following specific examples.

Fig. 1 is a schematic view of an independently detachable gear rotating core according to the present invention, which is assembled with an outer case 60 and an inner core 70 of a valve core.

As shown in fig. 2 to 5, the present invention relates to an independent detachable gear rotating core, which comprises a housing 10, a core body 20, an index plate 30, a marble 40, and a position limiting plate 50.

The housing 10 has a shaft hole 11 axially penetrating therethrough, a communicating groove 12 through which the stopper piece 50 passes from outside to inside, and an annular accommodating groove 13 in which the marble 40 is accommodated.

The core 20 has a shaft 21 inserted in the shaft hole 11 and a limiting groove 22 formed on the shaft 21 for cooperating with the limiting plate 50, wherein the limiting groove 22 is used for limiting the axial displacement of the core 20 relative to the shell 10.

The indexing disc 30 is sleeved on the shaft rod 21 and is formed with a plurality of gear grooves 31, and the marble 40 abuts against or is separated from the gear grooves 31 when the shell 10 and the core body 20 rotate relatively.

Thus, the present invention relates to an independent detachable gear rotating core, wherein the housing 10 can be assembled with the outer shell 60 of the valve core, the core 20 can be assembled with the inner core 70 of the valve core, i.e. the housing 10 and the outer shell 60 of the valve core can keep synchronous rotation, the core 20 and the inner core 70 of the valve core can keep synchronous rotation, and the gear reminding function is realized by using the click sound generated when the inner ball 40 is aligned with the gear groove 31 on the index plate 30.

As shown in fig. 1 to 3, as a specific embodiment, the housing 10 further has coupling teeth 14, and the coupling teeth 14 are used for being snapped with the outer shell 60 to allow the housing 10 and the outer shell 60 to rotate synchronously.

As shown in fig. 2 to 5, the core 20 further has a flange 23 formed at one end of the shaft 21 for sealing connection with the housing 10, and an elastic locking point 24 formed at the other end of the shaft 21 for locking with the core 70. In addition, in order to make the shaft 21 and the inner core 70 rotate synchronously and more conveniently, the cross section of the shaft 21 is hexagonal and matched with the inner core 70, so that the shaft 21 and the inner core 70 can keep rotating synchronously after being inserted.

In order to perform the sealing function, as shown in fig. 2 and 3, the present invention further includes at least a first sealing ring 25 and a second sealing ring 26, wherein the first sealing ring 25 is sleeved on the flange 23, so as to perform the function of sealing the gap between the flange 23 and the housing 10.

The second sealing ring 26 is used for sealing a gap between the shaft rod 21 and the housing 10, is sleeved on the shaft rod 21, and is specifically positioned between the limiting groove 22 and the dividing disc 30; thus, the first seal ring 25 and the second seal ring 26 are used to provide a better sealing function.

As shown in fig. 2 and 3, as an embodiment of the indexing disk 30 and the core body 20, which are synchronously rotated, the indexing disk 30 further forms a detent groove 32, and the core body 20 further has detent teeth 27 formed on the shaft 21 for engaging with the detent groove 32. In this way, the indexing plate 30 and the core body 20 always keep synchronous rotation by the snap-fit connection between the detent teeth 27 and the detent grooves 32.

As shown in fig. 4, a plurality of silencing grooves 28 are formed in the flange plate 23 in order to reduce noise generated by water flow.

The above embodiments and drawings are not intended to limit the form and style of the present invention, and any suitable changes or modifications thereof by those skilled in the art should be considered as not departing from the scope of the present invention.
