[0035] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0036] See also Figures 1 to 6 , is an anti-loosening locking device as embodiment 1 of the utility model, including a faucet body 10, a washer 20, and a locking nut 30. The faucet body 10 has an internally hollow screw portion 11; the washer 20 is a flexible member, and is sleeved on the outside of the screw portion 11; the locking nut 30 is threadedly connected to the screw portion 11; the upper end surface where the locking nut 30 and the washer 20 abut is provided with a plurality of anti-loosening steps 31. Since the washer 20 is a flexible member, after the locking steps are locked, the tops of the anti-loosening steps 31 can be embedded to prevent the locking nut 30 from loosening by itself. The anti-loosening locking device of the utility model is provided with anti-loosening steps 31 on the locking nut 30. After the locking nut 30 is tightened, the anti-loosening steps 31 will press on the washer 20, and cooperate with the flexible washer 20 to prevent the entire locking nut 30 from shifting by itself and becoming loose. The rotation direction of the locking nut 30 when it is locked is detailed in FIG. Figure 3 .

[0037] The washer 20 is a flexible elastic member. Specifically, the washer 20 is made of a rubber member, such as a rubber material. When the locking nut 30 is locked, some elastic force can be generated to support the locking nut 30 to prevent loosening.

[0038] Please refer to Figures 3 to 5 , the number of the anti-loosening steps 31 is 16-24, and the number of the anti-loosening steps 31 in this embodiment is 20. The anti-loosening step 31 includes an inclined surface 311 and a vertical surface 312; and the inclined surface 311 of the previous anti-loosening step 31 and the vertical surface 312 of the next anti-loosening step 31 form an angle α, and the degree of α is an acute angle, specifically, the degree of α is 45-80°; preferably, the degree of α in this embodiment is 69°.

[0039] An internal threaded hole 32 that mates with the screw portion 11 is provided inside the lock nut 30; a plurality of rotation steps 33 for rotation are provided on the outer wall below the lock nut 30, so that the lock nut 30 can be locked without using a special tool.

[0040] A faucet provided by the present utility model adopts the structure of an anti-loosening locking device.

[0041] In summary, the anti-loosening locking device of the present utility model prevents the entire lock nut from shifting and loosening on its own by providing an anti-loosening step on the lock nut. After the lock nut is tightened, the anti-loosening step presses on the washer, and in cooperation with the flexible washer.
