Abstract

The utility model relates to a dust flying preventing shield device for a percussion drill, which is composed of a front sealing ring, a pedestal which is sheathed outside a clamping head of a percussion drill and a bearing cage, and a close elastic member which is sheathed outside a drilling head, wherein the upper end of the close elastic member is connected with the front sealing ring and the lower end is connected with the pedestal. The upper end of the pedestal is hermetically connected with the drilling head, and the lower end is hermetically connected with the bearing cage. The utility model can cause dust, sand stones and drilled and cut things to be completely sealed in a dustproof shield. A percussion drill is used for upwards drilling holes, and the dust, the sand stones and the drilled and cut things can not fall outwards. The use is convenient, the working condition is obviously improved and the environmental pollution is reduced.

Description

The percussion drill dust cover
The utility model relates to electric impact drill, prevent a kind of guard apparatus of stirring up a cloud of dust.
Present electric impact drill is not equipped with dust guard, and the dust sandstone flies upward severity during use, particularly upwards perforating, dust and drilling thing drop on full the operator head and face and on one's body, it is very difficult, inconvenient to use, the working condition extreme difference, contaminated environment is serious.
The purpose of this utility model is to remedy the deficiencies in the prior art, and a kind of working condition, easy to use, percussion drill dust cover product of reducing environmental pollution of improving is provided.
Can take following technical scheme to realize purpose.
The percussion drill dust cover by preceding sealing ring, is sleeved on the outer base of percussion drill dop and bearing cage and covers in outside the drill bit, and the sealed elastic spare formation that upper end and preceding sealing ring, lower end are connected with base is on the base and drill bit sealing-in, lower end and bearing cage sealing-in.
The relative prior art of the technical program has following advantage and effect:
Dust, sandstone drilling thing all are encapsulated in the dust cover, and upwards perforating is not also understood not fall outward, uses very conveniently, obviously improves working condition, minimizing environmental pollution.
In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.
Accompanying drawing is a kind of structure and the user mode schematic diagram of percussion drill dust cover.
Embodiment 1, percussion drill dust cover are made of preceding sealing ring 1, sealed elastic spare 2, base 3 three parts.Preceding sealing ring has drill bit and drilling thing access hole in the middle of it, can adopt various softnesses or material full of elasticity to constitute in order to form sealing with body of wall.Base is by the profile of percussion drill dop and bearing cage part, make with rubber or plastics and so on, and its upper end is passed drill bit and sealing-in with it, is sleeved on outside, lower end and the bearing cage sealing-in of dop and bearing cage.Sealed elastic spare upper end is connected with base with preceding sealing ring, lower end, constitutes the spindle cavity volume, in order to collect the effluent of percussion drill, can adopt the material of better strain to constitute.Concrete structure everywhere can be taken the circumstances into consideration selected on demand.
In electric impact drill when work,, drill bit moves axially, and pushes away drill body and remains with metope by sealing ring before playing the shape part and making and combine closely, and effluent constantly falls in the cover.Electric drill moves forward dust cover strain backward, can effectively collect effluent.
Embodiment 2, percussion drill dust cover, on the basis of embodiment 1, preceding sealing ring 1 is made of rubber or plastics or rubber, plastic brush.
Embodiment 3, percussion drill dust cover, on the basis of embodiment 1, between base upper end and drill bit to brush 4 sealing-ins.Can adopt hair or wire brush, stop dust to enter in the percussion drill.
Embodiment 4, percussion drill dust cover, on the basis of embodiment 1 or 2 or 3, the cover 6 that sealed elastic spare 2 is made by internal layer spring leaf 5 and outside rubber and high resiliency textile constitutes.8-10 of spring leafs get final product.As shown in drawings, its serviceability, result of use are good.
Embodiment 5, percussion drill dust cover, on the basis of embodiment 1 or 2 or 3, sealed elastic spare 2 is a rubber.Promptly cast monolithic construction with rubber.

Claims (5)
