Description

Technical Field

[0001] The utility model belongs to the technical field of drinking water supply and relates to a faucet. Background Art

[0002] A faucet is a hardware product used to control the size of water flow output. It is very common in today's life. With the continuous advancement of technology, the types of faucets are becoming more and more diverse. In response to consumers' requirements for water quality, developers will add a second water channel based on the original water channel. The two water inlet channels are the water inlet channel and the water purification channel. Both channels are connected to the water outlet channel in the faucet and are controlled by the control handle respectively. In this way, users can draw water through water circulation according to their own needs.

[0003] Based on the above structure, the faucet also needs to be installed with two carbide tubes, which are fixed to the bottom of the faucet by welding. One of them is connected to the water purification channel, and the other is connected to the water inlet channel. The carbide tube connected to the water inlet channel is directly connected to the external water pipe, and the carbide tube connected to the water purification channel is connected to the water purifier. Furthermore, the two carbide tubes need to be passed through the through holes opened on the countertop, and then screwed to the carbide tubes through nuts and tightened against the bottom of the countertop, so that the faucet is firmly positioned on the countertop.

[0004] Although the above-mentioned faucet can guarantee the user's demand for water quality, there are great inconveniences in assembly and subsequent maintenance, which are specifically manifested as follows: First, in the process of assembling and locking the faucet with a nut, due to the structure of the faucet itself, the distance between the two carbide tubes is relatively small. Therefore, in the process of screwing the nuts, there will be interference between the two nuts, and the installation stability of the faucet cannot meet the specified requirements; second, after long-term use, the carbide tube will have internal scale accumulation, and the carbide tube will be bent or even broken due to improper operation. At this time, the faucet can only be replaced as a whole, and the replacement cost is very high. Summary of the invention

[0005] The purpose of the utility model is to solve the above problems in the prior art and to propose a faucet. The technical problem to be solved by the utility model is: how to reduce the maintenance and replacement costs while improving the assembly stability of the faucet.

[0006] The purpose of the utility model can be achieved through the following technical solutions: a faucet, comprising two alloy tubes and a body with two water inlet channels, characterized in that the two alloy tubes are plugged and clamped with the two water inlet channels, the faucet also includes a threaded sleeve detachably connected to the body and sleeved on the outside of the two alloy tubes, a nut is threadedly connected to the outside of the threaded sleeve, and the top surface of the nut has a plurality of locking teeth, and the plurality of locking teeth are arranged at intervals along the circumferential direction of the top surface of the nut.

[0007] The difference between this faucet and the prior art is that the two alloy tubes used to connect the external water pipe and the water purifier are respectively connected and fixed to the two water inlet channels of the main body by plugging. At the same time, before performing the above installation steps, a detachable connection solution is first used to install a threaded sleeve on the main body, and the threaded sleeve cooperates with the main body to achieve the connection and fixation of the main body countertop, thereby solving the nut interference problem that may exist when the alloy tube cooperates with the main body. Secondly, the threaded sleeve can also play a certain protective role. By hiding the connection between each alloy tube and the water inlet channel, the problem of looseness caused by collision during installation and subsequent use is effectively reduced. In addition, during assembly During the process, the threaded sleeve is inserted into the through hole pre-opened on the countertop, and is screwed upward from bottom to top through the nut, so that the top surface of the nut is finally pressed against the bottom of the countertop, and the bottom surface of the main body is pressed against the bottom of the countertop, and the main body is firmly fixed on the countertop through the screw locking action of the two. When performing this operation, the locking teeth on the top of the nut can reduce the force area, thereby achieving the maximum compression effect, ensuring the maximum clamping effect, and ensuring the assembly stability of the faucet. It is worth mentioning that the detachable alloy tube, threaded sleeve, nut and other components in this case can be disassembled and replaced separately when a fault occurs in the later stage, without the need to disassemble and replace the faucet as a whole, ensuring lower maintenance and replacement costs.

[0008] In the above-mentioned faucet, the bottom of the body has a columnar connection part, the bottom of the connection part is provided with a connection groove, the two water inlet channels penetrate the bottom wall of the connection groove, the circumferential inner wall of the connection groove is provided with an internal thread, and one end of the threaded sleeve is screwed with the circumferential inner wall of the connection groove. Specifically, the threaded sleeve is connected to the inner wall of the connection groove at the bottom of the connection part by threaded matching, thereby ensuring the connection stability of the threaded sleeve.

[0009] In the above faucet, the threaded sleeve is connected with a shielding cover located above the nut, the top of the shielding cover is against the end of the connecting part, and the shielding cover is embedded and clamped with an upper tightening pad located above the nut. Through the setting of the shielding cover, the edge of the through hole opened on the countertop is covered by the shielding cover to ensure aesthetics. At the same time, due to the setting of the upper tightening pad, the locking force formed by the threaded connection between the nut and the threaded sleeve pulls the body downward as a whole, so that the upper tightening pad presses the top of the countertop to ensure the assembly stability of the faucet.

[0010] In the above faucet, the bottom surface of the upper abutment pad has a plurality of annular upper protrusions along the circumferential direction, and the plurality of upper protrusions are arranged around the threaded sleeve, and each of the upper protrusions protrudes out of the cover opening of the shielding cover. The arrangement of the upper protrusions can reduce the contact area between the upper abutment pad and the table surface, thereby achieving the maximum degree of compression and ensuring the assembly stability of the faucet.

[0011] In the above faucet, the threaded sleeve is externally connected with a lower locking washer, and the lower locking washer is located between the upper locking washer and the nut. Through the arrangement of the lower locking washer, the locking force formed by the threaded connection between the nut and the threaded sleeve is transmitted to the bottom of the table through the lower locking washer, thereby maximizing the locking effect of the locking teeth on the nut and ensuring the assembly stability of the faucet.

[0012] In the above faucet, the top surface of the lower abutment pad has a plurality of annular lower protrusions along the circumferential direction, and the plurality of lower protrusions are arranged around the threaded sleeve. The arrangement of the lower protrusions can reduce the contact area between the lower abutment pad and the table surface, thereby achieving the maximum degree of compression and ensuring the assembly stability of the faucet.

[0013] In the above faucet, one of the alloy tubes extends outward from the lower end of the threaded sleeve and is bent outward, so as to ensure that the two alloy tubes are used to connect the external water pipe and the water purifier at one end, and avoid interference between the joints installed on the two alloy tubes later.

[0014] Compared with the prior art, this faucet has the following advantages:

[0015] 1. The alloy tube is connected by plug-in, and the threaded sleeve is screwed to the connecting groove in the connecting part of the main body. The threaded sleeve cooperates with the nut and the connecting part to clamp the upper and lower sides of the table. While ensuring the stable installation of the main body, the detachable connection between the components ensures lower maintenance costs in the later stage.

[0016] 2. The locking teeth arranged circumferentially on the nut cooperate with the upper protrusion on the upper clamping pad and the lower protrusion on the lower clamping pad to further increase the clamping force generated by the screw connection and ensure the installation stability of the body.
