[0019] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0020] like Figure 1-3 As shown, a water gun for an indoor fire hydrant includes a shell 1, in which a first tube body 2 is arranged, and a gun head 11 is arranged on the first tube body 2. The first tube body 2 is a rectangular parallelepiped, and a plurality of folding openings 21 arranged in a linear array are opened on all sides. A telescopic rod 22 and a fixed rod 23 are respectively arranged on each folding opening 21, and a spherical part 24 is arranged between the telescopic rod 22 and the fixed rod 23.

[0021] Specifically, when in use, connect the bottom of the first tube body 2 in the shell 1 to the faucet, then open the water valve, water enters the first tube body 2, and is sprayed through the gun head 11. When the angle needs to be adjusted, bend the first tube body 2. At this time, the telescopic rod 22 and the fixed rod 23 will be in a V shape or A shape through the spherical part 24 to limit the position, so as to prevent the weight from being too heavy when the water flows through, causing the gun head 11 to be pressed down, resulting in the angle of the water spraying being uncontrollable.

[0022] In the above scheme, the first tube body 2 is protected by the shell 1, water spraying is achieved through the gun head 11 on the first tube body 2, and the first tube body 2 and the shell 1 are bent through the folding mouth 21 on the first tube body 2, so as to adjust the water spraying angle of the gun head 11. Through the telescopic rod 22, the fixed rod 23 and the spherical part 24, it is achieved that the bending of the first tube body 2 and the strength of water spraying are guaranteed while adjusting the water spraying angle of the gun head 11, thereby avoiding shaking and deviation caused by the weight of water when spraying water.

[0023] As an embodiment further provided by the present invention, according to Figure 2 and Figure 3 As shown, the telescopic rod 22 and the fixed rod 23 are sleeved with an elastic member 25 .

[0024] Specifically, when the telescopic rod 22 and the fixed rod 23 are in a V-shape or an A-shape through the spherical member 24, the elastic member 25 is stressed to form a force against the weight of the water flow, further enhancing the strength of the first tube body 2 when the water flows through.

[0025] As an embodiment further provided by the present invention, according to Figure 2 and Figure 3 As shown, the second tube body 26 is disposed in the first tube body 2 , and the second tube body 26 includes a main board 261 , and side boards 28 are symmetrically disposed on both sides of the main board 261 , and the two side boards 28 and the main board 261 form a protruding member 100 .

[0026] Furthermore, a rotating shaft 27 is provided at the connection between the side plate 28 and the main plate 261 .

[0027] Furthermore, when the second tube body 26 is folded, the plurality of main boards 261 are spliced ​​together so that the diameter of the second tube body 26 changes.

[0028] Specifically, it should be noted that the default state of the protruding member 100 is a plane.

[0029] Furthermore, when the range of the gun head 11 is too short, the first tube body 2 is pulled inward, and the telescopic rod 22 is shortened. At the same time, the protruding piece 100 on the straight surface will be switched to a cube. At this time, the main board 261 will be pushed outward by the two side plates 28 to form the protruding piece 100. At this time, the diameter of the second tube body 26 becomes the diameter of the main boards 261 in the multiple protruding pieces 100, shortening the diameter to increase the flow rate and thus increase the range.

[0030] Working principle: When in use, connect the bottom of the first tube body 2 in the shell 1 to the faucet, then open the water valve, water enters the first tube body 2, and water is sprayed through the gun head 11. When the angle needs to be adjusted, bend the first tube body 2. At this time, the telescopic rod 22 and the fixed rod 23 will be in a V shape or A shape through the spherical part 24. At the same time, when the telescopic rod 22 and the fixed rod 23 are in a V shape or A shape through the spherical part 24, the elastic part 25 will be stressed to form a force that resists the weight of the water flow, further strengthening the strength of the first tube body 2 when the water flows through, limiting the position, and preventing the weight of the water flow from being too heavy when passing through, causing the gun head 11 to be pressed down, resulting in the angle of the water spray being uncontrollable.

[0031] When the range of the gun head 11 is too short, the first tube body 2 is pulled inward, and the telescopic rod 22 is shortened. At the same time, the protruding piece 100 on the straight surface will be switched to a cube. At this time, the main board 261 will be pushed outward by the two side plates 28 to form the protruding piece 100. At this time, the diameter of the second tube body 26 becomes the diameter of the main boards 261 in the multiple protruding pieces 100. The diameter is shortened to increase the flow rate and thus increase the range.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
