Description
Technical field
The utility model relates to a kind of percussion drill spring boosting dust cover, belongs to percussion drill dust control technology field.
Background technology
Percussion drill is the indispensable electric tool of architectural engineering.Yet percussion drill is not in use taked any measure that prevents the dust diffusion usually, can produce a large amount of drilling cuttings dust, grievous injury health and surrounding environment.For a change this situation, people also did many trials, just once developed the easy dust exhaust apparatus that is enclosed within on the drill bit as German Bosch company, indivedual enterprises of Korea S also developed to have and blew and the cleaner of dust suction two-way function, and more domestic producers also did a lot of trials in this respect.Lv Yunsong teaches and has developed " percussion drill dust guard " in 2003, and has obtained utility model patent, the patent No.: ZL200320110381.6.Owing to have the defective that is difficult to overcome all the time at aspects such as serviceability, manufacturing costs, cause this class research to fail to enter the practical stage always, do not see the dust guard that is useful on the percussion drill on the market yet.As seen, the percussion drill of developing a kind of practicality is with dustproof its obvious social and the construction value of being covered with.The shortcoming of the percussion drill that generally uses is at present: dust is big, influences the healthy of people and environment on every side, does not meet the environmental protection theme that is rooted in the hearts of the people now!
Summary of the invention
This people do purpose provide a kind of simple in structure, change easily, the percussion drill spring boosting dust cover of good dustproof effect.
A kind of percussion drill spring boosting dust cover, comprise dust gathering arrester and dust gathering arrester compactor, described dust gathering arrester comprises base plate and the cover body that is installed on the base plate, be equipped with on cover body and the base plate and make the drill bit through hole that drilled, on the contact-making surface of cover body and wall elastic seal ring is installed, it is characterized in that: described compactor comprises compression spring, the piston rod in spring strut, installation and the spring strut, and piston rod one end links to each other with the compression spring by piston, and the other end links to each other with dust gathering arrester; Also be provided with the connector that it is connected with percussion drill on the dust gathering arrester compactor.
The impulse stroke of percussion drill is longer, in the whole stroke of boring, guarantee the contact force of plastic bowl and metope in the dust gathering arrester, and on the one hand, the size of this power will be controlled at and can prevent that dust from leaking, and on the other hand, this power does not influence normal running again.The compression spring closely contacts with piston in the spring strut, and during work, dust gathering arrester contacts with metope, and under the reaction force of metope, piston rod promotes piston spring is compressed, and guarantees that everything goes well with your work, good seal.After hole drill was good, when drill bit withdrawed from, dust gathering arrester was pressed on the metope all the time under the effect of spring force, thereby formed reliable contact force.Spring boosting dust cover is wanted and can both be convenient to use at the drill bit of all size as an annex of percussion drill, and easy and simple to handle, and certain versatility is arranged.
The drilling cuttings dust leaks along helical flue of drill during the percussion drill operation, stop dust to leak, just must guarantee to seal between dust gathering arrester and drill bit, simultaneously, in drill bit when rotation, is with strong axial vibration and radially wobble, therefore also must the solution drill bit and seal between the friction and wear problem.In this product, stuffing-box is installed on base plate, in stuffing-box, be placed with seal felt, the dust gathering arrester front end is installed sealing rubber ring, rubber ring has certain suction when contacting with wall, can prevent that dust from leaking, simultaneously cushioning effect be arranged also, overcome the demand that closely contacts with wall of vibrating when satisfying work; Felt cooperates with drill bit closely, because of the flexibility of felt itself make it and drill bit between almost do not have the space, leave a fixed gap between felt and the stuffing-box, therefore, can rotate with drill bit, in addition, felt abuts against on the base plate under the axial thrust effect of helical flue of drill, form sealing, add the centrifugal action that the felt rotation produces, can prevent effectively that dust from overflowing from the rear end.The dust gathering arrester bottom is provided with scavenge port, can quickly and easily the dust in the dust gathering arrester be discharged, and scavenge port can be connected with dustbin by soft catheter.
Compared with prior art, the described percussion drill spring of the design boosting dust cover, the dust that helical flue of drill can be taken out of when percussion drill is worked all is collected in the dust gathering arrester, and fast and safely discharges, and does not have the phenomenon that leaks.Its advantage is: long service life, easy to operate, low price, manufacturing be simple, change easily and dust does not have and leaks, and helps people's healthy and environmental sanitation.

The specific embodiment
A kind of innovative design product, percussion drill spring boosting dust cover, it comprises cover body 1, base plate 2, piston rod 3, piston 4, compression spring 5, spring strut 6, thread plug 7, connector 8.The transparent rigid plastics of cover body 1 usefulness is made, and links to each other with base plate 2 with bolt.Stuffing-box 11 is installed on base plate 2, and stuffing-box 11 passes chucking as shown in Figure 3 and locks with steel pin from base plate two holes.Be placed with seal felt 12 in stuffing-box 11, seal felt is selected felt for use.The dust gathering arrester mouth is equipped with elastic seal ring 13, adopts rubber ring here, and rubber ring adopts natural elastic rubber to make.Be provided with dust emission mouth 10 in the dust gathering arrester bottom, dust can be discharged fast by floss hole.Drill bit can pass base plate 2, stuffing-box 11, seal felt 12, elastic seal ring 13.And can rotate together with seal felt 12.Compression spring 5 is contained in the spring strut 6, and piston 4 is contained in the front end in the spring strut, after thread plug 7 is contained in spring strut 6, and with spring compression, spring is attached to spring strut 6 inner faces with piston 4 push-tights, and piston 4 and piston rod 3 are close to by screw thread, and piston rod 3 other ends and base plate 2 are close to.Be welded with two connectors 8 on the spring strut 6, connector 8 is close to by bolt and percussion drill, thereby whole device is fixed on the percussion drill.
During use, use bolted on percussion drill in dust catcher, it is vertical with wall that percussion drill keeps, thereby elastic seal ring 13 contacts fully with wall before making dust gathering arrester, guarantees sealing.Because dust gathering arrester and base plate all are transparent, thus can see drill bit and wall position contacting, and can adjust easily.After adjust the position, press the percussion drill switch, start working, when percussion drill was worked, the operator applied axial force by percussion drill to drill bit, and elastic seal ring 13 is adjacent to wall, wall applies reaction force to dust gathering arrester simultaneously, under the effect of wall reaction force, compression spring 5 is compressed, and piston 4 moves in spring strut 6, and with drill bit shaft to the movement velocity equal and opposite in direction, oppositely opposite, thus guarantee that elastic seal ring 13 contacts with wall well all the time on the dust gathering arrester, and dust can not revealed.Seal felt 12 in the stuffing-box 11 can and rotate with the drill bit contact, thereby guarantees the sealing function of base plate 2.The dust that helical flue of drill is taken out of can be discharged from dust gathering arrester lower end scavenge port apace, and is collected.When the boring end-of-job, drill bit withdraws from wall gradually, and at this moment the axial force of drill bit disappears, because spring is compacted, the elastic force of spring is passed to base plate 2 by piston rod 3, thereby passes to dust gathering arrester, make elastic seal ring 13 and wall continue to be adjacent to, guarantee none silk leakage of dust.
