Abstract
The utility model provides a dustproof drill chuck. The dustproof drill chuck comprises a drill body and clamping jaws, wherein a dustproof piece which is transversely distributed is arranged at an outlet of adjacent clamping jaws of the drill body; and a positioning piece of the dustproof piece is further arranged on the drill body. A groove which is transversely distributed is formed at the outlet of adjacent clamping jaws of the drill body; the dustproof piece is arranged in the groove; the positioning piece of the dustproof piece is an elastic retainer ring; and the elastic retainer ring is distributed in an inner wall slot at the opening direction of the groove. According to the dustproof drill chuck, the dustproof piece is added, and through a sealing dustproof way, the dust protection can be ensured on structure; and the dustproof drill chuck can work for a long time under various dust severe environments.
Description
Technical field
The utility model relates to a kind of dustproof drill chuck.
Background technology
Existing drill chuck, as Fig. 1 structure, drill chuck is without any the device that prevents that dust from entering.When working in drilling concrete or the comparatively serious environment of other dust, dust easily runs in drill chuck, and is upwards obvious especially during the drilling operation.Dust runs into drill chuck inside from jaw position bead section, divides to form in jaw and inner linkage portion and overstocks, and dust is lived inner link gear clamping stagnation, thereby causes drill chuck to lose efficacy.
Summary of the invention
The utility model is mainly to solve the deficiency that existing drill chuck exists, and a kind of drill chuck of simple in structure, easy to process, good dustproof effect is provided.This drill chuck can make dust can not run into drill chuck inside, reduces drill chuck and can not use because clamping stagnation causes scrapping the waste that brings, and satisfies instructions for use under the comparatively serious environment of various dust.
The utility model solves the problems of the technologies described above the technical scheme that adopts:
A kind of dustproof drill chuck includes drill body and jaw, and the adjacent jaw of described drill body exit is provided with the lateral arrangement dust guard, also is provided with the keeper of dust guard on described drill body.
In described drill body, adjacent jaw exit is provided with the groove of lateral arrangement, and described dust guard is placed in described groove; The keeper of described dust guard is circlip, and described circlip is arranged in the inner wall groove of described slot opening direction.
Described dust guard is arranged in the outer face of drill body, and the keeper of described dust guard is drill sleeve, described drill sleeve and drill body interference fit, and described dust guard is positioned at the drill body outer face by drill sleeve and drill sleeve overlaps between the bottom.
Described dust guard is rubber ring, and the rubber ring center is provided with through hole, and corresponding through hole surrounding is provided with some lines of cut.
Described dust guard is hairbrush.
The beneficial effects of the utility model are: increased dust guard, adopted sealed dust-proof, guaranteed the protection of dust from structure, all can work long hours under various dust adverse circumstances.

Fig. 1 is original drill chuck structural representation;
Fig. 2 is the utility model the first structural representation;
Fig. 3 is the utility model the second structural representation;
Fig. 4 is the dust guard cutaway view.
The specific embodiment
Embodiment is described in further detail the utility model below in conjunction with accompanying drawing.
Embodiment one:
As shown in Fig. 2,4, a kind of dustproof drill chuck includes drill body 2 and jaw 1, and the adjacent jaw of described drill body exit is provided with lateral arrangement dust guard 3, and described dust guard is rubber ring, and the rubber ring center is provided with through hole 31, and corresponding through hole surrounding is provided with some lines of cut 32; Also be provided with the keeper of dust guard on described drill body.In described drill body, adjacent jaw exit is provided with the groove of lateral arrangement, and described dust guard is placed in described groove; The keeper of described dust guard is circlip 4, and described circlip is arranged in the inner wall groove of described slot opening direction.Dust guard 3 with drill chuck inside and external isolation, can not partly run into the interlock part from jaw dust in use, reaches dust-proof effect.
Embodiment two:
As shown in Figure 3, a kind of dustproof drill chuck includes drill body 2 and jaw 1, and the adjacent jaw of described drill body exit is provided with lateral arrangement dust guard 3, and described dust guard is rubber ring, and the rubber ring center is provided with through hole, and corresponding through hole surrounding is provided with some lines of cut; Also be provided with the keeper of dust guard on described drill body.Described dust guard is arranged in the outer face of drill body, and the keeper of described dust guard is drill sleeve 5, described drill sleeve and drill body interference fit, and described dust guard is positioned at the drill body outer face by drill sleeve and drill sleeve overlaps between the bottom.Thereby make drill chuck isolate external dust and the inner link gear of drill chuck when the clamping drilling bit drilling, reach dust-proof effect.
Embodiment three:
A kind of dustproof drill chuck includes drill body and jaw, and the adjacent jaw of described drill body exit is provided with lateral arrangement dust guard 3, and described dust guard is hairbrush; Also be provided with the keeper of dust guard on described drill body.In described drill body, adjacent jaw exit is provided with the groove of lateral arrangement, and described dust guard is placed in described groove; The keeper of described dust guard is circlip 4, and described circlip is arranged in the inner wall groove of described slot opening direction.Dust guard 3 with drill chuck inside and external isolation, can not partly run into the interlock part from jaw dust in use, reaches dust-proof effect.
