Abstract

The utility model relates to a front lid lock device for vacuum cleaner comprising a locking body matched with end surface of a front lid of a vacuum cleaner, a hook-shaped pinch plate arranged in the front lid and a spring base of a lying spring is arranged in a base. A spring pressure plate connected with an inward horizontally extending section of the locking body is inserted into the spring base and mutually supported and pressed with the spring. An inverse hook is provided at a bending arm connected with the inward horizontally extending section of the locking body, and the inverse hook is mutually locked with upper and lower part of an opening of the hook-shaped pinch plate. A limit bottom plate is fixedly arranged at back of the bending arm of the locking body arranged on inner reinforcement of the base, and a bending horizontal plate at top of the limit bottom plate is arranged above the inverse hook. The locking body and the spring pressure plate, the bending arm and the inverse hook arranged on the bending arm are processed into a whole. The utility model has the advantages of simple structure and convenient application. Opening and closing of the front lid can be realized by merely inward pressing and releasing the locking body, thus providing a front lid lock device with excellent performance for small vacuum cleaners.

Description

The preceding lid and cover device of dust catcher

Technical field

The utility model relates to a kind of annex of dust catcher, especially a kind of preceding lid and cover device that is used for dust catcher protecgulum and base folding.

Background technology

The dust catcher of selling on the market, its movable protecgulum button generally all is installed on the end face of protecgulum, and swing protecgulum button makes buckling on the barb that links to each other with the protecgulum button and the base fasten or open, thereby makes protecgulum do the folding activity on base.The preceding lid and cover device of this routine must be sufficiently large, otherwise it is not firm that protecgulum and base fasten, and this protecgulum button is applicable to large and medium-sized dust catcher.For this reason, to design a kind of folding flexible for Small-sized suction cleaner, fastens firm preceding lid and cover device, is the problem of pendulum this field technology personnel.

Summary of the invention

The purpose of this utility model is at the defective of above-mentioned prior art and deficiency, pushes flexibly for the horizontal small dust catcher provides, the preceding lid and cover device of the dust catcher of folding with convenience.

For achieving the above object, the technical measures that the utility model is taked are: the preceding lid and cover device of this dust catcher comprises a buckling body that coincide with dust catcher protecgulum end face, a hook-type buckle that is fixed in the protecgulum, in base, be provided with the spring base of accumbency spring, the spring bearer plate that links to each other with the inside horizontal-extending section of buckling body stretches into spring base and the spring front end compresses mutually, with on the bent over arms that the inside horizontal-extending section of buckling body links to each other a barb is arranged, this barb and hook-type buckle opening are upper and lower to fasten mutually relatively.

The described rear that is positioned at the buckling body bent over arms on the interior muscle of base is fixed with spacing base plate, before and after the buckling body during displacement, so that the base plate of barb and buckle peristome is interlocked and breaks away from, the top of this spacing base plate is positioned at the level board that bent over arms barb top is provided with bending.

Spring bearer plate that described buckling body links to each other with buckling body and bent over arms and barb integral body are processed into one.

The utility model compared with prior art, structure is simpler, as long as push the buckling body on the protecgulum, spring bearer plate and bent over arms in the buckling body are made stretching motion, protecgulum button and buckle fasten or break off relations, the folding function of convenient realization dust catcher protecgulum.

Fig. 3 is the cutaway view of preceding lid and cover device.

The specific embodiment

The preceding lid and cover device of this dust catcher comprises that 3, one of a buckling body that coincide with the end face of protecgulum 1 is fixed in the buckle 2 of protecgulum 1, and buckle is hook-type, and its opening and is fixed by the interior cylinder in screw and the protecgulum inwardly.In base 6, be provided with a spring base 7, spring 4 is lying in the spring base 7.Be connected with vertically downward a spring bearer plate 10 on described buckling body 3 sections of extending internally, this spring bearer plate stretches into spring base 7 and compresses mutually with the front end of spring 4.Be connected with vertically upward a bent over arms 8 on the described buckling body section of extending internally, this bent over arms top is provided with barb 9, and barb is relative with the opening of buckle 2, up and down the phase hook.Spring bearer plate 10 on the described buckling body, bent over arms 8 and barb 9 are processed into one with buckling body 3 integral body.When pressure is pressed buckling body, for make spring bearer plate 10, bent over arms 8 can be elastic reposefully, the rear that is positioned at buckling body bent over arms 8 on the interior muscle of base 6 is fixed with spacing base plate 5, the distance of bent over arms and spacing base plate 5 can be enough to make bent over arms when moving forward and backward on the buckling body, the base plate of barb on the bent over arms and buckle 2 is interlocked and breaks off relations, the level board of one bending is arranged at the top of spacing base plate, and this bending level board is positioned at barb 9 tops, rocks when flexible to prevent buckling body.

During use, Pressing fastener zoarium 3, the spring bearer plate 10 on the buckling body make spring 4 compressions, the translation inwards of the bent over arms on the buckling body meanwhile, and barb on it and buckle 2 break away from, and the protecgulum of dust catcher is opened.Loosen buckling body, because the screen resilience of spring 4 promotes spring bearer plate 10 forward, buckling body resets.When the dust catcher protecgulum covered, the barb on the bent over arms and buckling body base plate be hook mutually, realized dust catcher protecgulum and base 6 fastenings.

Claims
