Draw from the above mentioned; Make service cover and rosette assembling form the service cover assembly through draw-in groove and protruding engaging, make the assembling of service cover and rosette more firm, simultaneously; Because rosette and service cover are assembled into one; The service cover assembly is realized and being connected of end cap through bindiny mechanism, thus the assembly process of simplification water heater end cap, the duplication of labour that reduces a staff.
Preferably, the inner surface at said rosette is provided with buckle; On the end face of end cap, correspondingly be provided with the jack that engages with said buckle.
Draw from the above mentioned, fixedly compare through screw with end cap, reduced amount of parts, thereby can reduce the assembly process of water heater end cap with service cover in the prior art.
Preferably, be provided with cylindrical portion at the inner surface of the outer rim of service cover, said draw-in groove circumferentially is arranged on this cylindrical portion along this cylindrical portion; On the inner edge of rosette, be formed with the groove of depression to the inside, on the side surface of this groove, be formed with said convexity, said cylindrical portion is embedded in the said groove.
Draw from the above mentioned; The adaptive service cover that makes through cylindrical portion and groove rotates along groove; Snap in the draw-in groove until convexity; And till service cover can not rotate, thus the location of having realized service cover and rosette with simple structure be connected, the assembling that can reduce service cover and rosette is with screw and assembly process.
Preferably, the number of said buckle and jack is more than three, and arranges along circumferential equidistance.
Draw from the above mentioned, adopt this structure, can make the connection between end cap and the service cover assembly have good stable property.
Preferably, said service cover is provided with from the rosette outer surface and connects the screw mounting hole to inner surface, and said rosette is provided with the screw post corresponding to this screw mounting hole, and screw passes said screw mounting hole and is combined on the said screw post.
Draw from the above mentioned, further to fixing between service cover and the rosette, avoid owing to reasons such as vibrations come off service cover through screw connection structure.
Preferably, the nut surface at said screw is equipped with in order to the screw that hides screw stifled.
Draw from the above mentioned, block, thereby improve the becoming more meticulous of water heater end cap outward appearance with attractive in appearance through stifled can the formation of screw to screw.
Preferably, said end cap is the right end cap of water heater.This is convenient to be applicable to the structure of existing water heater.
Description of drawings
Fig. 1 is the integrally-built front view of expression right end cap;
Fig. 2 be along A-A among Fig. 1 to sectional view;
Fig. 3 be along B-B among Fig. 2 to dovetail groove and the sketch map of protruding engaging.
The specific embodiment
Right end cap with water heater is an example below, specifies the water heater end cover structure that the utility model specific embodiment provides in conjunction with Fig. 1-Fig. 3.
Shown in Figure 1 is the overall structure figure of right end cap, as shown in Figure 1, and right end cap has the end cap 1 of an annular, and this end cap 1 is arranged on the right part of the housing of water heater, forms the cover round of the annular that is provided with opening.Rosette 3 and service cover 2 in order to the closed end cap opening are installed on end cap 1.Constitute the right end cap of water heater by end cap 1, rosette 3 and service cover 2, parts such as computer plate, temperature controller, breaker mainly are installed in the inside of this right end cap.Wherein, service cover 2 is installed on the end cap 1 removably, water heater is maintained with convenient in the future; Rosette 3 is arranged between end cap 1 and the service cover 2, in order to improve the outward appearance of whole end cap, strengthens its aesthetic feeling.In following description, described outer rim all refers to radially the side away from the centre of end cap 1, and described inner edge all refers to radially the side near the centre of end cap 1; Said inboard (inner surface) all refers to vertically towards the inner side of water heater master tube; The said outside (outer surface) all refers to vertically away from the inner side of water heater master tube.
As shown in Figure 2, be formed with a stage portion 11 (constituting the end face of the utility model) at the inner edge of end cap 1, offer jack 12 in these stage portion 11 equal intervals.On the inner surface of the outer rim of rosette 3, be formed with the buckle 33 suitable with jack 12, buckle 33 is equally distributed in the inner surface of the outer rim 32 of rosette 3.Jack 12 is six with buckle 33, can make end cap 1 and being connected of rosette 3 have good stable property.
As shown in Figure 1; Service cover 2 is provided with from the outside of rosette 3 and connects to inboard screw mounting hole (not shown); Rosette 3 is provided with the screw post (not shown) corresponding to this screw mounting hole, and screw 4 passes the screw mounting hole that is arranged on the service cover 2 successively, be arranged at the screw post on the rosette 3 and be combined on the screw post.Like this,, avoid further to fixing between service cover 2 and the rosette 3 through screw connection structure owing to reasons such as vibrations come off service cover.Be provided with screw on the surface of the nut of screw 4 stifled 5, and this screw stifled 5 can form the effect of blocking to screw 4, thereby improves becoming more meticulous and aesthetic feeling of water heater end cap outward appearance.
Adopt Fig. 1-right end cap structure shown in Figure 3; In process of production; Need each parts not packed separately, directly make dovetail groove 22 and stop bit muscle 32 closely engage the location prepackage that realizes service cover 2 and rosette 3 through rotation service cover 2 and rosette 3, with screw 4 rosette 3 and service cover 2 tightened together then; Stifled screwing blocks up 5 on screw 4 again, thereby forms an integral type service cover assembly.Can directly integral type be keeped in repair assembly through the engaging of above-mentioned buckle 33 and jack 12 is assembled on the end cap 1.Like this, the independent encapsulation that can omit such as rosette 3, service cover 1 etc. reaches operations such as assembling one by one, thereby simplifies the assembling process of water heater end cap.
