Description

Water purifier top cap fixing device Technical Field The utility model relates to a water purifier, in particular to a water purifier top cover fixing device. Background The current water purifier top cover is fixed mainly by adopting two technical schemes, namely, four screw hole grooves are formed in the top cover, and the shell and the top cover are locked in all directions through four screws. Although the scheme provides higher fixing strength, the technical defects of complicated manual operation steps and increased cost of screw fittings exist, and especially when the screw hole groove is formed in the outer side of the shell, the appearance integrity of the product is seriously affected. The other improvement scheme adopts a compound fixing mode that two screws are combined with a buckle, although the screw consumption is reduced and the production efficiency is improved, structural weakness exists in a locking area far away from the screw due to weak stress of the buckle structure, and quality problems such as loosening of the buckle, warping of the edge of the top cover and the like are easily generated when falling or transportation vibration is encountered. The two schemes have obvious technical defects in the aspects of assembly convenience, production cost control and structural reliability, and a novel fixing device with the advantages of operation convenience, economy and structural stability is required to be designed. Disclosure of utility model In order to achieve the above object, the present utility model provides a water purifier top cover fixing device, comprising: The top cover comprises a horizontal plate part and a curved plate part, wherein the curved plate part extends forwards and is bent to be vertical; The front shell is provided with a limiting buckle groove matched with the limiting buckle and a buckle groove matched with the buckle; the two side plates are provided with slide fastener grooves which are in sliding connection with the slide fasteners; A rear shell provided with a threaded hole corresponding to the threaded hole seat; The top cover sequentially passes through the limit of the limit buckle and the limit buckle groove, the pre-fixing of the buckle and the buckle groove, the horizontal sliding limit of the slide buckle and the slide buckle groove, and finally the full-freedom degree constraint fixing is completed through the screw fastening of two screws penetrating through the threaded hole seat and the rear shell threaded hole. Further, the threaded hole seat, the slide fastener, the limit fastener and the buckle are integrally injection molded with the top cover. Further, the limit buckling groove, the buckling groove and the front shell are integrally injection molded. Further, the slide fastener groove and the side plate are integrally injection molded. The device combines the three-dimensional structures of the buckle, the slide buckle and the limit buckle, and finally realizes the overall constraint of six degrees of freedom of the top cover by combining the final strong fixation of the two screws, can greatly enhance the shock resistance of the top cover when the top cover falls or is transported on the premise of reducing the using amount of 50% of screws and hiding the mounting hole site to improve the attractive degree of the product, and obviously reduces the manual operation strength by a staged assembly mechanism (pre-positioning-sliding locking-final locking). The conception, specific structure, and technical effects of the present utility model will be further described with reference to the accompanying drawings to fully understand the objects, features, and effects of the present utility model.
