DETAILED DESCRIPTION

[0033] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0034] Example

[0035] like Figure 1-5 As shown, this embodiment provides a technical solution: an anti-theft device for a water outlet of a water control machine, comprising a body 1 of the water control machine, a water inlet and a water outlet 2 are provided on the body 1, a connecting seat 4 is fixedly mounted on the water outlet 2, the connection between the connecting seat 4 and the water outlet 2 is welded, the interior of the connecting seat 4 is hollow, a connecting head 12 is coaxially fixedly connected to the water pipe 5, and the connecting head 12 is connected to the water pipe 5, the connecting head 12 can be slidably inserted into the connecting seat 4, a blind hole slot is coaxially opened on the connecting head 12, the water outlet 2 is inserted into the slot, so that the water outlet 2, the water pipe 5 and the interior of the connecting seat 4 are in a connected state;

[0036] Since the water pipe 5 may be detached from the connecting seat 4, causing the water outlet 2 to be unauthorizedly connected, thereby causing a waste of water resources, in this embodiment, a mounting seat 7 is welded on the outer wall of the connecting seat 4, a sliding cavity in the form of a blind hole is opened inside the mounting seat 7, and a pin shaft 10 is coaxially penetrated on the mounting seat 7, and the pin shaft 10 can slide freely on the connecting seat 4. In addition, an arc-shaped clamping block 19 is fixedly connected to one end of the pin shaft 10 that penetrates into the connecting seat 4, and an annular clamping groove 13 for the arc-shaped clamping block 19 to engage is coaxially opened on the outer edge of the connecting head 12. A card reader 3 is also installed on the receiving seat 4, and the card reader 3 is electrically connected to a controller (such as a single chip microcomputer, etc.). An electromagnet 20 is fixedly installed in the sliding cavity of the mounting seat 7, and the power supply of the electromagnet 20 is turned on and off by the controller. In addition, a sliding ring 18 is engaged in the sliding cavity, and the sliding ring 18 is fixedly sleeved on one end of the pin shaft 10 that penetrates into the sliding cavity. The sliding ring 18 forms a sliding fit with the inner wall of the sliding cavity. In addition, the sliding ring 18 is made of any one of iron, cobalt and nickel materials, so that the sliding ring 18 and the electromagnet 20 form a magnetic fit. A spring 9 is sleeved on the pin shaft 10, and the two ends of the spring 9 in the direction of elastic force elastically press against the sliding ring 18 and the electromagnet 20 respectively. When the water pipe 5 needs to be disassembled, first use an external RFID card to stick on the surface of the card reader, the card reader signal is turned on and the controller can control the electromagnet 20 to be powered on, so that the electromagnet 20 generates magnetism after being energized and generates suction to the sliding ring, so that the sliding ring drives the pin shaft to slide downward, so that the arc-shaped card block is out of the engagement state with the annular card groove, so that the water pipe can be detached from the connecting seat, and when the water pipe 5 is disassembled, the water pipe 5 can be disassembled from the connecting seat. When installing the water pipe, directly remove the RFID card from the card reader, so that the controller disconnects the power supply to the electromagnet, and then the spring produces elastic resistance against the sliding ring, so that the arc-shaped card block can move upward and engage in the annular card groove, so that the connector will not be separated from the connecting seat, and the water outlet is prevented from being stolen. In addition, the end of the connector 12 exposed from the connecting seat 4 is fixedly covered with a limit ring 6, which is used to limit the movement of the connector 12 toward the inner side of the connecting seat 4 to prevent the outlet from being inserted into the slot too deep;

[0037] When the water pipe is separated from the water outlet, the residual water in the water pipe may leak out from the pipe mouth of the water pipe. Therefore, in this embodiment, a fixed plug 11 is fixedly connected in the slot, and two connecting grooves 16 are provided on the end surface of the fixed plug 11. A connecting shaft 14 is coaxially slidably penetrated on the fixed plug 11. A through hole is provided on the fixed plug 11 for the connecting shaft 14 to move freely through. A sealing plug 15 is coaxially fixedly connected to one end of the connecting shaft 14 inserted into the slot, and the axial projection area of ​​the sealing plug 15 can cover the connecting groove 16, so that when the sealing plug 15 and the end surface of the fixed plug 11 are abutted, the abutting surfaces of the two are in a sealed state. A fixing rod 17 is welded to the other end of the connecting shaft 14, and the slot A return spring 8 is installed inside, and the two ends of the return spring 8 in the elastic direction elastically press against the sealing plug 15 and the inner wall of the slot respectively. When the water outlet is inserted into the slot, the end face of the water outlet will contact the fixing rod and can drive the connecting shaft 14 to slide toward the inner side of the connecting seat, so that the sealing plug is separated from the state of abutting against the end face of the fixing plug, so that the water in the water outlet can enter the slot through the connecting groove and enter the water pipe, so that the water outlet is connected to the water pipe. When the water pipe is disconnected from the water outlet, the return spring elastically presses against the sealing plug, so that the sealing plug and the end face of the fixing plug are abutted, so that the connecting groove is closed by the sealing plug, so that the water in the water pipe will not leak out from the connecting groove.

[0038] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
