Description

Assembling structure for snap-in faucet housing

Technical Field

The utility model relates to a tap subassembly technical field, in particular to buckle formula tap casing equipment structure.

Background

The common faucet structure is that a water outlet assembly is arranged in a faucet shell to serve as a flow passage, and has the advantages that: the water flow only contacts the water outlet assembly and does not contact the faucet shell, so that the lead pollution caused by the material of the faucet shell is avoided, the faucet shell has more material choices, the production, manufacturing and molding of the faucet shell are facilitated, and the material cost is reduced.

At present, most of common faucet shells adopt a two-piece design, namely, a lower shell is formed to be used as a main part of the faucet shell, and an upper shell is formed to be assembled and sealed on the lower shell, so that an installation space is formed inside the faucet shell for a water outlet assembly to be installed inside.

In order to overcome the drawback that the conventional upper housing and lower housing are screwed and fixed by exposed bolts, which affects the aesthetic appearance of the assembled faucet, the chinese patent No. CN 210827701U discloses a mounting structure of a water outlet device and a water outlet device, so that the assembled fasteners or bolts are completely hidden in the faucet housing, thereby improving the aesthetic appearance of the product.

However, the above-mentioned patent still has some problems in structural design, for example, although the upper housing and the lower housing can be screwed and fixed at two ends, namely the remote end and the near end, respectively by means of hidden fasteners or bolts, the remote fasteners must extend into the mounting space from the mounting holes of the lower housing, and can be screwed and fixed to the fastening mating member of the upper housing, it can be understood that, before assembly, the water outlet head must be detached from the fixing seat of the water outlet assembly to allow the mounting holes for the fasteners to enter the mounting space for screwing and fixing, and after screwing and fixing, the water outlet head is installed back to the fixing seat to complete the assembly operation and shield the fasteners. It can be seen that such a design adds complexity and time cost to the assembly operation, especially since some of the water outlet heads are assembled to the water outlet assembly before installation, which results in the water outlet head having to be disassembled and then replaced during the installation operation. Second, the remote fastener must be locked from below the lower housing at an oblique angle, which can easily cause tools, such as a flat or cross driver, to hit the lower housing, or be forced to use a shorter tool. In addition, the more fasteners and screw lock designs, the higher precision requirement is required, and accordingly, the yield of the product is easily affected, and the material and assembly cost is easily increased.
