Description
Technical Field
[0001] The utility model relates to the technical field of faucets, in particular to an anti-loosening threaded faucet. Background Art
[0002] There are many ways to connect the water inlet pipe of the existing washing machine to the faucet. The common way is to directly snap the quick connector on the faucet or to thread the quick connector and the faucet. There is a disadvantage of using the threaded connection method. When the washing machine is running, it will shake, causing the joint of the washing machine water inlet pipe and the faucet thread to loosen, thereby causing water leakage. Utility Model Content
[0003] The purpose of the utility model is to overcome the shortcomings and deficiencies of the prior art and to provide a loosening-proof threaded faucet.
[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: an anti-loosening threaded faucet, comprising a faucet body and a quick connector threadedly connected to the faucet body, and also comprising an anti-loosening washer pressed between the faucet body and the quick connector, wherein the anti-loosening washer is provided with a first ratchet surface facing the quick connector.
[0005] By adopting the above technical solution, an anti-loosening washer is provided. After tightening, the first ratchet surface of the anti-loosening washer is pressed against the quick connector, thereby increasing the friction between the two and preventing the quick connector and the faucet body from loosening.
[0006] As a preferred technical solution of the utility model, the first ratchet surface includes a plurality of ratchet teeth, and the arrangement direction of the plurality of ratchet teeth is the same as the tightening direction of the quick connector.
[0007] By adopting the above technical solution, the quick connector rotates along the ratchet arrangement direction when screwing until the anti-loosening washer is compressed between the quick connector and the faucet body. When rotating in the opposite direction, the friction between the quick connector and the first ratchet surface needs to be overcome to avoid loosening.
[0008] As a preferred technical solution of the utility model, a plurality of ratchets are arranged obliquely on the anti-loosening washer, the ratchets are crescent-shaped and the thickness of the ratchets gradually increases from the inner edge to the outer edge of the anti-loosening washer.
[0009] By adopting the above technical solution, the thickness of the ratchet gradually changes from the inner end to the outer end, and the cross-section is an irregular cross-section. When rotating along the ratchet arrangement direction of the first ratchet surface, the ratchet of the quick connector is under pressure in the tightened state. When rotating in the opposite direction, the outer end part of the ratchet will provide a resistance, increasing the friction between the end face of the quick connector, thereby playing a role in preventing loosening.
[0010] As a preferred technical solution of the utility model, a second ratchet surface is provided on the side of the anti-loosening washer opposite to the first ratchet surface, the second ratchet surface has the same structure as the first ratchet surface, and the ratchet teeth of the first ratchet surface and the second ratchet surface are arranged in a clockwise direction along their respective end faces.
[0011] By adopting the above technical solution, when viewed from the side, the ratchet arrangement directions of the first ratchet surface and the second ratchet surface are opposite, but when viewed from their respective end faces, the ratchets are arranged in a clockwise direction of their respective end faces. Setting ratchets on both sides can increase the friction between the block joint and the first ratchet surface, and between the faucet body and the second ratchet surface.
[0012] As a preferred technical solution of the utility model, the faucet body includes a threaded water outlet pipe, and the quick connector is provided with an internal thread threadedly connected to the threaded water outlet pipe.
[0013] As a preferred technical solution of the utility model, a spring washer is also provided which is sleeved outside the threaded water outlet pipe. When the quick connector and the faucet body are tightened, the spring washer and the anti-loosening washer are compressed between the two.
[0014] By adopting the above technical solution, the spring washer and the anti-loosening washer are sequentially inserted into the threaded water outlet pipe, and the quick connector is tightened to make the spring washer and the anti-loosening washer under pressure. After the spring washer is flattened, its rebound force will keep the compression force and friction force between the threads, thereby playing an anti-loosening role. The spring washer is the preferred method. Of course, flat washers or serrated washers can also be used. The gasket material can be metal or rubber. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The specific embodiments of the present utility model are described below in conjunction with the accompanying drawings.
[0023] like Figures 1 to 5 The anti-loosening threaded faucet shown in the figure includes a faucet body 1 and a quick connector 2 threadedly connected to the faucet body 1, and also includes an anti-loosening washer 3 pressed between the faucet body 1 and the quick connector 2. The anti-loosening washer 3 is provided with a first ratchet surface 4 on the side facing the quick connector 2. In this embodiment, the quick connector 2 is used to connect to the water inlet pipe of the washing machine (this is the prior art and will not be elaborated in detail).
[0024] By providing the anti-loosening washer 3, after tightening, the first ratchet surface 4 of the anti-loosening washer 3 is pressed against the quick connector 2, thereby increasing the friction between the two and preventing the quick connector 2 and the faucet body 1 from loosening.
[0025] The first ratchet 5 surface 4 includes a plurality of ratchet teeth 5 and the arrangement direction of the plurality of ratchet teeth 5 is the same as the tightening direction of the quick connector 2. When screwing, the quick connector 2 rotates along the arrangement direction of the ratchet teeth 5 until the anti-loosening washer 3 is compressed between the quick connector 2 and the faucet body 1. When rotating in the opposite direction, the friction between the quick connector 2 and the first ratchet surface 4 needs to be overcome to avoid loosening.
[0026] A plurality of ratchet teeth 5 are arranged obliquely on the anti-loosening washer 3, the ratchet teeth 5 are crescent-shaped and the thickness of the ratchet teeth 5 gradually increases from the inner edge to the outer edge of the anti-loosening washer 3, the thickness of the ratchet teeth 5 gradually changes from the inner end to the outer end, and the cross section is an irregular cross section. When the ratchet teeth 5 are rotated along the arrangement direction of the first ratchet surface 4, the ratchet teeth 5 are compressed in the tightened state of the quick connector 2, and the outer end part of the ratchet teeth 5 will provide a resistance when rotating in the opposite direction, thereby increasing the friction between the end face of the quick connector 2 and playing an anti-loosening role.
[0027] A second ratchet surface 6 is provided on the side of the anti-loosening washer 3 opposite to the first ratchet surface 4. The second ratchet surface 6 has the same structure as the first ratchet surface 4.
