Abstract
The dust-proof cover for electric drill is characterized by that it is composed of a spring and a cylindrical plastic film shell covering the spring, and the lower end of the plastic film shell and tail end of the spring are fixed on a fixing device which can be fixed on the non-rotating neck portion of the drill bit, and the upper end of the plastic film shell and upper end of the spring are fixed on its locking device.
Description
The present invention relates to the dust cover that the security protection of the safety device of electric hand drill, particularly electric impact drill is used.
Present electric hand drill; when particularly electric impact drill is worked; dust and sandstone can outwards splash at a high speed; work the mischief near the health of people operator and the operation field; especially when ceiling is carried out bore operation; its harmfulness is bigger; therefore people often will be with safety goggles and mouth mask when using electric impact drill; though protected eyes like this and can not suck sand dust; but dust and sandstone still can drop on the operator on the face; and operating personnel influence sight line and breathing because of wearing safety goggles and mouth mask, make troubles to work.
The purpose of this invention is to provide a kind of sand, dirt of when electric drill is worked, preventing and disorderly fly the electric drill dust guard that human body is damaged.
Technical solution of the present invention is such, a spring is arranged, have one to be placed in the outer cylindrical shape overlay overcoat of spring, the lower end of plastic foil overcoat and the tail end of spring are fixed on the fastening devices that can be fixed on the non rotatable neck of electric drill head, and the upper end of plastic foil overcoat and the upper end of spring are fixed on the locking device.
Above-described spring can be conical, cylindrical.
The fastening devices that is fixed on the non rotatable neck of electric drill head of the present invention includes a fixed muffle, this fixed muffle is an annular, there is outside or inside warp mouth its upper end, the lower end circle that is used for embedding knot spring, several pieces the pin sheets that can adjust its folding are extended in its lower end, are fixed with the band shape button that can regulate degree of tightness in the outside of pin sheet.
The upper end of the above plastic foil overcoat and the upper end of spring are fixed on the locking device, its locking device is an annular coupling collar, the end face of coupling collar is the plane, the groove that its bottom surface just has the circle with the spring upper end embed can be used for sticking press fit plastic foil overcoat at the cylindrical wall of coupling collar.
The lower end of spring of the present invention is connected with fixed muffle, and the upper end is connected by the outer set upper side of coupling collar and plastic foil, and the nylon bracelet is fixed on the outer wall of fixed muffle, pocket of whole plastic foil overcoat formation with the following end closure of plastic foil overcoat.When during use dust cover being installed by a plurality of pin sheets of fixed muffle lower end, catch formula to be fixed on the non rotatable neck of electric impact drill, by the lock set of banded button, make the pin sheet can catch neck more tightly again.Drill bit is trapped in this dust cover middle part, this dust cover top was higher than to bore and chews the tip when spring was upheld naturally, the coupling collar of spring upper end, its below center line has semicircle groove one, be used for the circle of spring upper end is embedded wherein, and conveniently replaced new plastic film overcoat, several band ears can be arranged under the plastic foil overcoat, be used for the dress of banded button.When the drill bit operation, when drill bit contacted with drilled object, spring was compressed, and its tension force is close to this dust cover top all the time with the plane of drilled porous body, dust that disperses and sandstone are stopped to fall by the plastic foil overcoat and are collected in the pocket of plastic foil overcoat formation, thereby reach dustproof effect.When the plastic foil overcoat played dustproof effect, its transparent characteristic made the operator can observe the boring target of this dust cover at any time.
Advantage of the present invention is to prevent dust, and the operator is played the effect of safeguard protection, and is convenient to observe and operation, and is practical, is convenient to promote.
Below in conjunction with accompanying drawing embodiments of the invention are described:
Fig. 1 organigram of the present invention;
Fig. 2 user mode of the present invention and organigram;
Fig. 3 is used to take in the card pincers schematic diagram of taking in of the present invention;
Fig. 4 the present invention takes in the user mode schematic diagram.
According to Fig. 1, shown in 2, the present invention has a spring 1, spring 1 is conical, a columnar overlay overcoat 4 that is placed in outside the spring 1 is arranged, the tail end of the lower end of plastic foil overcoat 4 and spring 1 is fixed on the fastening devices that can be fixed on the non rotatable neck of electric impact drill head, fastening devices includes a fixed muffle 2, this fixed muffle 2 is an annular, there is outside or inside warp mouth its upper end, the lower end circle that is used for embedding knot spring 1, several pieces the pin sheets that can adjust its folding are extended in its lower end, are fixed with banded a mouthful 5 of can regulate degree of tightness in the outside of pin sheet.The upper end of the upper end of plastic foil overcoat 4 and spring 1 is fixed on the locking device, its locking device is an annular coupling collar 3, the shape of coupling collar 3 is the annulus of planar band chamfering, the end face of coupling collar 3 is the plane, the groove that its bottom surface just has the circle with spring 1 upper end embed can be used for sticking press fit plastic foil overcoat 4 at the cylindrical wall of coupling collar 3.
Shown in Fig. 3,4, being used to take in the card pincers of taking in of the present invention has a circular base plate, and chassis central authorities are fixed with a fork that both sides are parallel, the movable rotation of proximal portion of fork be fixed with a card, other has a disc pincers that the center is porose.According to shown in Figure 4, the present invention is inserted in and is taken on the chuck, compression spring 1 is lower than the card that vertically gets up until coupling collar 3 after, the pincers of circular discoid is inserted in card under, after card is turned to level, the present invention soon is compressed into minimum volume, is convenient to collect.
