Abstract
The present invention provides a structure capable of preventing vacuum cleaner caster interior from producing vibration. Said structure includes the following several portions: small caster fixed on the vacuum cleaner base seat; fixing cylinder positioned in the central position on the base seat mounting recessed groove for fixing the described small caster and matched with small caster hole; partition board and spring which are successively placed between the described small caster and base seat mounting recessed groove, the described partition board has a central hole through which the fixing cylinder positioned in the described base seat mounting recessed groove can be passed.
Description
Technical field
The present invention relates to a kind of dust catcher, particularly a kind of structure that prevents caster shock of cleaner.
Background technology
Dust suction is a kind of sanitation and hygiene electrical equipment, is used for removing the dust in ground, carpet, wall, furniture, clothing and various slits.Profile classification according to dust catcher can be divided into vertical type dust collector, horizontal dust collector and portable dust collector etc.
The dust catcher general structure includes the motor of dust collector that is generated suction by the power supply that imports, form air path system motor air inlet, suction nozzle, flexible pipe, gather the dust collect plant of inhalation (inhalatio).
In general, horizontal dust collector comprises protecgulum, bonnet and drain pan.Preceding caping is established the hose jockey, the drain pan rear portion is provided with horizontal winder and gathers the control of dust tube of inhalation (inhalatio), the drain pan front portion is provided with motor of dust collector, and importing the path of motor air inlet through the gas that control of dust tube top cover is removed foreign substances with filtering tank and filter core, the exhaust outlet through being provided with air discharge grille is discharged to the dust catcher outside again.Be provided with dismountable filter core in the control of dust tube, be convenient to clear up foreign substances such as dust.Be provided with convenient roller that moves and the horn ring of being convenient to turn in the bottom of dust catcher.
As shown in Figure 1, a hole is arranged in the middle of the Caster 1, the body base has an outstanding positioning cylinder 2 that cooperates with described hole, the top head of cylinder is the boss of a diameter big slightly (more bigger than the hole in the middle of the Caster), so just can be fixed on bound feet 1 on the body base, belong to excessive between Caster 1 and the body base and cooperate.But because in conjunction with not cushioning transition, sometimes dust catcher runs into small stair in the time of work, Caster comes off easily.As the horn ring of above-mentioned structure dust catcher, when being movably walking through ladder or meeting obstacle, dust catcher can jolt, and this moment, motor and the internal structure thereof to dust catcher had injury, directly influenced the service behaviour of dust catcher.
Summary of the invention
For solving the problem that exists in the above-mentioned technology, the purpose of this invention is to provide a kind of structure that prevents the inner vibrations of dust catcher castor, be beneficial to when dust catcher walking process ladder or obstacle, prevent to produce jolt, and reduce injury motor and internal structure.
For achieving the above object, the technical solution used in the present invention provides a kind of preventing in the dust catcher castor
The structure of portion's vibrations, include the Caster that is fixed on the dust catcher base, there is the fixed cylinder that cooperates with the Caster hole center that the base of fixing described Caster is installed on the groove, wherein: between described Caster and base installation groove, be provided with dividing plate and spring in succession, described dividing plate is provided with and makes described base that the centre bore that the fixed cylinder in the groove is passed is installed, described base is installed groove and is provided with the restriction protrusion symmetrical with fixed cylinder, and spring is installed on the restriction protrusion.
Fixed cylinder in the described base installation groove is spring, dividing plate and described Caster hole successively, and Caster and base are installed and fixed.
One side of described dividing plate is provided with the boss symmetrical with its central hole location.
Between installing restriction protrusion on the groove, the boss of described dividing plate and base be fixed with spring.
Effect of the present invention is to install at body base and Caster to combine, dividing plate and spring have been added, platform body base and Caster springing stroke on original drain pan, have been deepened, prevent that dust catcher from use running into when jolting, cause coming off of Caster, avoided damage, improved the service behaviour of dust catcher motor and dust catcher internal structure.
Description of drawings
Fig. 1 is the dust catcher Castor structure schematic diagram of prior art;
Fig. 2 is a dust catcher Castor structure schematic diagram of the present invention.
Among the figure:
1, Caster 2, positioning cylinder 3, dividing plate
4, spring 5, restriction protrusion
The specific embodiment
Reaching embodiment in conjunction with the accompanying drawings is illustrated the structure of caster shock of cleaner that prevents of the present invention.
As shown in Figure 2, the structure that prevents the inner vibrations of dust catcher castor of the present invention, include the Caster 1 that is fixed on the dust catcher base, there is the fixed cylinder 2 that cooperates with the Caster hole center that the base of fixing described Caster is installed on the groove, between described Caster 1 and base installation groove, be provided with dividing plate 3 and spring 4 in succession, described dividing plate 3 is provided with and makes described base that the centre bore that the fixed cylinder in the groove is passed is installed, described base is installed groove and is provided with the restriction protrusion 5 symmetrical with fixed cylinder 2, and spring 4 is installed on the restriction protrusion 5.
A kind of mode is that the fixed cylinder 2 that described base is installed in the groove is passed spring 4, dividing plate 3 and described Caster hole successively, and Caster 1 and base are installed and fixed.Be enclosed within fixed cylinder 2 outsides by a slightly larger spring 4 of diameter, dividing plate 3 is fixing with Caster 1 pressing, and can play the effect of damping.
Also can on a side of described dividing plate 3, be provided with the boss symmetrical with its central hole location, install on the groove at described base and to be provided with the restriction protrusion 5 symmetrical, between the restriction protrusion 5 on the boss of described dividing plate 3 and the base installation groove, be fixed with spring 4 with fixed cylinder.The spring diameter that this fixed form adopted is slightly smaller, and described boss and restriction protrusion can be set to the 2-3 place, but must be symmetrical, makes the suffered pressure of dividing plate 3 even.This structure plays the effect of damping equally.
The inner structure that shakes of dust catcher castor that prevents of the present invention is realization like this;
The first step: at first mounting spring 4;
Second step: buckle dividing plate 3 again, the Facad structure of dividing plate 3 be the through hole in centre (than the boss slightly larger in diameter of fixed cylinder 2 end faces of the protrusion of dust catcher body base), and two boss are aimed at two springs and put well;
The 3rd step: Caster is installed: Caster is installed, the boss diameter of fixed cylinder 2 end faces of the protrusion of the boring ratio dust catcher body base in the middle of the Caster is little, after being pressed into assembling, the two cooperation belongs to interference fits, and Caster 1 just is fixed on the body base.
