Abstract
A positioning sleeve for electric drill dust covers comprises a sleeve part and a support part. The sleeve part is positioned to a fixed part of an electric drill. The support part extends from a bit of the electric drill to be connected with a dust cover and surrounds and isolates a rotating part of the electric drill. The support part is provided with a dust collection channel communicated with the inside of the dust cover. The support part is provided with an inner bearing corresponding to the rotating part of the electric drill. The sleeve part is tightly fitted and positioned to the fixed part of the electric drill. The support part is in a grid or tubular shape. The support part is connected with the dust cover via screws. The positioning sleeve is light-permeable. The positioning sleeve has the advantages that dust prevention of the dust cover is improved greatly, and operation safety is improved for users.
Description
Technical field
The present invention relates to a kind of fixed part that is positioned electric drill and with the rotation section of electric drill around isolation, then the design that links for dust cover, particularly a kind of positioning sleeve of dust-proof cover for electric drill.
Background technology
Use a large amount of dust that electric drill produces can disperse and fill the air in air everywhere, not only have a strong impact on air quality, affect simultaneously workmen's expiratory dyspnea, also can welding clean and tidy and be difficult to cleaning; Therefore, dust-proof cover for electric drill 10a as shown in Figure 1, in it can be coated on the drill bit 22 of electric drill 20, and coordinate and be formed with most gauffer sections on this dust cover, so that this dust cover has elastic-restoring force after pressing, therefore during bit bore, this dust cover is along with the degree of depth that pierces of drill bit is done flexible the adjustment, still can be resisted against outside drill hole, the drilling cuttings dust of being discharged when holing to accept, treat that boring is complete, this dust cover will be subjected to the elastic-restoring force effect of gauffer section, return back to the drill bit coated state and prevent that the drilling cuttings dust from dropping; Yet, directly being positioned the fixed part 21 of electric drill 20 due to existing dust cover, the axial dimension of dust cover integral body can be very long, the vibration that dust cover can cause because of when boring, and make dust cover produce significantly vibration, and cause the not good to wall end adaptation of dust cover, reduce its dust-proof effect.
Summary of the invention
Technical problem underlying to be solved by this invention is, overcomes the defects that prior art exists, and a kind of positioning sleeve of dust-proof cover for electric drill is provided, and it has the effect that significantly promotes the dust cover dust-proof effect, and has the effect that promotes user's handling safety.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of positioning sleeve of dust-proof cover for electric drill includes: a fit section is positioned the fixed part of electric drill; And a support portion, this fit section extends to the direction of the drill bit of electric drill certainly, and links for dust cover, and the rotation section of electric drill is given around isolation.
In addition, further be formed with dust collecting trough with the dust cover internal communication in this support portion.Again, the inner rotation section of electric drill relatively, this support portion is provided with bearing.Separately, this fit section close-fitting is positioned the fixed part of electric drill.Again one, this support portion is grizzly bar shape or tubular.Another person, this support portion and dust cover screw togather link.Moreover, this positioning sleeve light-permeable.
The invention has the beneficial effects as follows, it has the effect that significantly promotes the dust cover dust-proof effect, and has the effect that promotes user's handling safety.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the structural representation of existing dust-proof cover for electric drill.
Fig. 2 is structural representation of the present invention.
The number in the figure explanation:
10a, 10b dust cover
20 electric drills
21 fixed parts
22 drill bits
23 rotation sections
30 positioning sleeves
31 fit sections
32 support portions
321 dust collecting troughs
33 bearings
The specific embodiment
At first, see also shown in Figure 2, positioning sleeve 30 light-permeables of the present invention and including: a fit section 31, close-fitting is positioned the fixed part 21 of electric drill 20; And the support portion 32 of grizzly bar shape or a tubular, section 31 extends to the direction of the drill bit 22 of electric drill 20 from this fit, and screw togather link for dust cover 10b, and the rotation section 23 of electric drill 20 is given around isolation (being available for users to grip), separately be provided with bearing 33 in the inner rotation section 23 of electric drills relatively, this support portion 32, can increase the stability of structure and reduce vibration; Further be formed with dust collecting trough 321 with dust cover 10b internal communication in this support portion 32 again.
Based on above-mentioned formation, setting of the present invention can allow the contraction in length of dust cover 10b, effectively reduces the vibration that dust cover 10b causes because of boring, stablizes driving fit in order to do the wall end that supports that makes dust cover 10b, and has the effect that significantly promotes the dust cover dust-proof effect.Moreover by around isolation, the user can directly be gripped on positioning sleeve 30 of the present invention, separately has the effect that promotes user's handling safety due to the rotation section 23 of electric drill 20.Again, the drilling cuttings dust that dust collecting trough 321 of the present invention produces in the time of can allowing boring is concentrated, convenient follow-up dust cleaning.
The above, it is only preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
In sum, the present invention is on structural design, use practicality and cost benefit, meet industry development fully required, and the structure that discloses is also to have unprecedented innovative structure, have novelty, creativeness, practicality, the regulation that meets relevant patent of invention important document is therefore mention application in accordance with the law.
