Referring to fig. 1, an embodiment of the present invention provides a sealing device for a water rocket, including: sealing post 1 and sealing ring 2. A plurality of annular mounting grooves 11 are formed in the outer side surface of the upper end of the sealing column 1, and the adjacent annular mounting grooves 11 are arranged in parallel at intervals; one or more sealing rings 2 are arranged in the annular mounting groove 11 in a one-to-one correspondence manner.

In the above embodiment, a plurality of annular mounting grooves 11 are formed in the outer side surface of the upper end of the sealing column 1 at intervals, a plurality of sealing rings 2 are arranged in the annular mounting grooves 11 in a one-to-one correspondence manner, and the sealing device of the water rocket can be formed by arranging different numbers of sealing rings 2 on the sealing column 1, so that the sealing effect is different due to the different numbers of the sealing rings 2. The sealing device of the water rocket can control the launching height of the water rocket by arranging different numbers of sealing rings 2.

In a preferred embodiment, the number of the annular mounting grooves 11 is three, the three annular mounting grooves 11 are sequentially arranged along the length direction of the sealing column 1, and the adjacent annular mounting grooves 11 are arranged in parallel at intervals. A sealing ring 2 can be arranged in each annular mounting groove 11.

Of course, in other embodiments, the number of the annular mounting grooves 11 is not limited to the above, for example, four or five, and the number of the annular mounting grooves 11 may be changed according to actual requirements.

Referring to fig. 2 and 3, the sealing post 1 is cylindrical, and a position-limiting plate 3 is further disposed at a middle portion of an outer side surface of the sealing post, and the position-limiting plate 3 has a circular horizontal cross section. Base 5 and the arrow body can dismantle the connection, just be equipped with a sealed section of thick bamboo 51 in the base 5, be formed with through-hole 511 in the sealed section of thick bamboo 51, a sealed section of thick bamboo 51 is inserted and is located in the arrow body, and can pass through-hole 511 gives the internal portion of arrow inflates.

More preferably, the upper end of the sealing post 1 may be inserted into the through hole 511, and the limiting plate 3 abuts against the lower side surface of the base 5, so as to prevent the sealing post 1 from being inserted too far into the through hole 511, which may result in the sealing post 1 being unable to be taken out.

More preferably, one or more sealing rings 2 are arranged on the sealing column 1, and the sealing rings 2 are in interference fit with the inner side wall of the through hole 511. Each sealing ring 2 can generate a certain friction force with the inner side wall of the through hole 511, and the more sealing rings 2 are arranged on the sealing column 1, the larger the generated friction force is.

Of course, in other embodiments, the horizontal cross section of the limiting plate 3 may be another shape, such as square, triangle, etc.

In a preferred embodiment, the lower end of the sealing column 1 is further provided with a plurality of grooves 13, specifically two grooves 13, and the two grooves 13 are symmetrically disposed on two sides of the lower end of the sealing column 1. The grooves 13 can increase the friction force when a human hand holds the finger. When the sealing post 1 needs to be inserted into or pulled out of the through hole 511, a person can directly pinch the two grooves 13 and then insert or pull out the grooves. In order to increase the friction force, a plurality of friction strips 14 are arranged in each groove 13, and adjacent friction strips 14 are arranged in parallel at intervals. The friction strip 14 protrudes out of the surface of the groove 13, so that friction force generated when a human hand holds the massage tool is greatly increased.
