The specific embodiment
Core of the present utility model is to provide a kind of percussion drill, for reducing or avoiding dust impact to bore user's adverse effect.
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
Please refer to Fig. 1 to Fig. 6, the structural scheme of mechanism of a kind of percussion drill that Fig. 1 provides for the utility model specific embodiment scheme; Fig. 2 is the top view of Fig. 1; Fig. 3 is the structure explosive view of the percussion drill in the utility model specific embodiment scheme; Fig. 4 is the structural front view of the dust cover in the utility model specific embodiment scheme; Fig. 5 is the right view of Fig. 4; Fig. 6 is the structural front view of the bracing frame in the utility model specific embodiment scheme.
In a kind of specific embodiment, the utility model provides a kind of percussion drill, comprises percussion drill body 5, drill chuck 9 and drill bit 8, and drill chuck 9 is arranged at percussion drill body 5, for drill bit 8 is installed.This percussion drill is also arranged with telescopic dust cover 7 on drill bit 8, one end of dust cover 7 is sealingly fastened in the periphery of drill chuck 9 by bracing frame 6, the other end opening of dust cover 7, is also provided with the scale 1 being arranged in parallel with drill bit 8 on bracing frame 6, scale 1 can be connected in bracing frame 6 pull.
Concrete, the dust or the particle that produce in order to prevent from holing splash out from dust cover 7, and one end of dust cover 7 is provided with sealing ring 11; Bracing frame 6 is provided with retaining ring 10, for the sealing ring of dust cover 7 11 being sealingly fastened in to the periphery of drill chuck 9, retaining ring 10 in the present embodiment fixes sealing ring 11 by the first screw 4, and certainly, mode fixes sealing ring 11 also can to adopt buckle or be threaded etc.
Because drill bit 8 is hidden by dust cover 7, user time can not see that drill bit 8 pierces the degree of depth of interior of articles in boring, so, this programme in dust cover 7 outer setting the scale 1 being arranged in parallel with drill bit 8.Concrete, bracing frame 6 is provided with for the installing hole 12 of scale 1 is installed, scale 1 can be done linear reciprocation and slide in installing hole 12, when holing, scale 1 is against the surface of drilled porous body, and along with the relative installing hole 12 that carries out of boring slides, the distance that installing hole 12 slides is the degree of depth of boring, so arrange, can person easy to use grasp the degree of depth of boring.
In order to make scale 1 keep stable in sliding process, preferably, the present embodiment is provided with spacing ring 2 in dust cover 7 Shanghai, and spacing ring 2 is set in the periphery of scale 1, and can on scale 1, slide along with the flexible of dust cover 7.In order further to improve the stability of scale 1, preferably, the quantity of spacing ring 2 is a plurality of.
Because scale 1 can slide at installing hole 12 internal freedoms, so, when this percussion drill is during in idle state, scale 1 is not easy to deposit, even may in installing hole 12, skid off or lose, in order to facilitate depositing of scale 1, this programme be provided with for locking the second screw 3 of scale 1 on bracing frame 6, when this percussion drill is when idle, only need tighten the second screw 3 just can guarantee that scale 1 can not skid off installing hole 12.Certainly, also can be provided with stopping means at the two ends of scale 1, or adopt the fixed forms such as buckle to prevent that scale 1 from skidding off in installing hole 12.
For dustproof better, preferably, the present embodiment is the length that is greater than drill bit 8 by the Design of length of dust cover 7, so just can with dust cover 7, collect dust or particle better.
It should be noted that, the dust cover 7 in this programme is made by telescopic material, such as elastic resin, rubber or other elastomeric materials etc., and preferably, the dust cover 7 in this programme is bellows.
When using this percussion drill to carry out drilling operation, along with drill bit 8 constantly pierces object to be processed, 7 of dust covers are blocked in body surface and shrink gradually, dust or particle that boring produces can not splash everywhere owing to being subject to stopping of dust cover 7, and remain in the inner chamber of dust cover 7, therefore, user can not be subject to the adverse effect of dust or particle etc. when holing, the scale 1 can pull being arranged on bracing frame 6 is convenient to user's keyhole degree of depth, visible, this programme is convenient operation not only, and has improved security.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
