The assembly structure schematic diagram of the water heater that Fig. 1 provides for a kind of detailed description of the invention of the utility model;
Fig. 2 is the partial structurtes enlarged diagram of part A in Fig. 1.
Detailed description of the invention
Core of the present utility model is to provide a kind of housing assembly, and the assembly structure of this housing assembly is comparatively solid and reliable; Meanwhile, a kind of water heater applying above-mentioned housing assembly is provided.
In order to make those skilled in the art person understand the utility model scheme better, below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Please refer to Fig. 1 and Fig. 2, the assembly structure schematic diagram of the water heater that Fig. 1 provides for a kind of detailed description of the invention of the utility model; Fig. 2 is the partial structurtes enlarged diagram of part A in Fig. 1.
In a specific embodiment, housing assembly provided by the utility model, comprise middle housing 11, the both ends of middle housing 11 are respectively arranged with end cap 12, the assembling end edge portion of end cap 12 have to extend inside end cap 12 in flanging 121, the both ends of middle housing 11 have choke 111, edge, the two ends portion of middle housing 11 has the outer flanging 112 extended towards the outside of middle housing 11, the annular reducing groove 113 with interior flanging 121 snap-fit engagement is formed between outer flanging 112 and choke 111, the edge part of interior flanging 121 and the inwall of annular reducing groove 113 fit.
By flanging in mutual snap-fit engagement 121 and annular reducing groove 113, achieve reliably fixing between middle housing 11 and end cap 12, and assembling process is simple and easy to do, only need the end of end cap 12 with middle housing 11 fasten and interior flanging 121 is snapped in annular reducing groove 113, greatly reduce labour intensity and the Whole Equipment production cost of workman; The edge part of interior flanging 121 and the inwall of annular reducing groove 113 fit, effectively can avoid the spillover of foamed material in follow-up foaming operation process, not only reduce the follow-up labour intensity of staff, also ensure that globality and the aesthetic measure of the water heater housing assembly after overall assembling.
