Abstract

The utility model relates to a modified dresser, which is suitable for carrying out wall dressing cleaning before rendering, oil painting, wallpaper sticking and other sites. The utility model comprises a handhold main pipe which is a hollow cylinder, a motor arranged on the middle and the lower part of the handhold main pipe, a siphon which is connected with a dressing assembly-equipped and a minor through hole-opened disk on an end connected with the handhold main pipe on the other end, and a flexible siphon arranged between the front head of the handhold main pipe and the through hole. Thereby, the handhold main pipe, the flexible siphon and the small through holes opened on the disk form a dust absorption pipe. The dust produced during the operation is absorbed by the dust collector through the dust absorption pipe to kill off the dust pollution of the working site.

The described hand-held person in charge's end is connected with dust catcher.

According to a kind of improved sander that the utility model provides, prior art has following advantage relatively:

Several persons in gap between small through hole on the upper channel that the utility model relates to, soft siphunculus, the disk and disk and the sticking dish are combined together, and have formed a dust absorption passage.Soft siphunculus is located at wherein cleverly, relends to help dust catcher, not only can play the dust suction effect, can not produce pollution when making work, and simple and reasonable, easy for installation.

Description of drawings:

Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structural representation of workpiece polishing mechanism;

Fig. 3 is an explosive view of the present utility model.

The specific embodiment:

Referring to Fig. 1, shown in Figure 2, a kind of improved sander that provides according to the utility model, comprise the hand-held person in charge 1, be installed in the hand-held motor 15 of being responsible for 1 middle and lower part, the bend pipe 2 that is connected with the hand-held person in charge 1 front portion, the other end of bend pipe 2 links to each other with disk 3, disk 3 is provided with workpiece polishing mechanism 4, the hand-held person in charge 1 is a hollow cylinder, have a small through hole 31 on the disk 3, be provided with a soft siphunculus 5 between the hand-held person in charge's 1 front end and the small through hole 31, this soft siphunculus 5 not only is one section dust absorption passage between through hole 31 and the front end of handing the person in charge 1, and the flexion performance is good, simple in structure, install rationally, low price.

Motor 15 is installed in hand-held 1 the middle and lower part of being responsible for, so not only can be so that the balance of whole sander and control, and meet the design of ergonomics; Hand-held 1 inside of being responsible for is provided with a dividing plate 11, is to cause driving snake 16 to be polluted in order to prevent dust in the upper channel 12 from falling in the lower channel 13; One end of fixed mount 18 is connected with the hand-held person in charge 1, the internal perisporium at soft siphunculus 5 two ends is socketed in respectively on the periphery wall of first perisporium 14 that fixed mount 18 other ends are provided with and second perisporium 32 on the disk 3, and all use clasp 7 to be buckled on the periphery wall at soft siphunculus 5 two ends, so not only connect reliably, and can prevent that the dust in the dust absorption passage from leaking and contaminated environment; The centre bore 33 that disk 3 is provided with not only makes things convenient for being connected of driving snake 16 and workpiece polishing mechanism 4, and reasonable in design; One end of bend pipe 2 is that to extend into the hand-held opening part of being responsible for 1 front portion 34 inner and contact with dividing plate 11, thus both link together can be more firm; The part of driving snake 16 is located in the lower channel 13, and it all is for better protection driving snake 16 in order to avoid it is polluted that another exposed parts coats with sheath 17, thereby prolonged its service life; Nylon bruss 36 is installed in by screw it is connected reliably, nylon bruss 36 all exposes to disk 3 with abrasive material 42 and nylon bruss 36 is in same horizontal level with abrasive material 42, so not only can effectively realize the effect of polishing, and play the effect of protection wall; There is gap 6 between disk 3 and the workpiece polishing mechanism 4, so not only be convenient to workpiece polishing mechanism 4 and can realize that effectively thereby polishing work is carried out in rotation, and can reach pick-up performance at last so that the dust in when work enters dust absorption passage with it by this gap 6 by the suction of dust catcher; Hand-held be responsible for 1 and bend pipe 2 all use materials such as aluminium matter, not only cheap, and in light weight, be suitable for operation.

Sander is connected with the mains, the hand-held motor of being responsible on 1 15 will be started working, the workpiece polishing mechanism 4 that drives on the disk 3 by driving snake 16 turns round again, thereby realized polishing work, workpiece polishing mechanism 4 is combined together a dust absorption passage of formation at the dust in when work by the gap 6 between disk 3 and the workpiece polishing mechanism 4, small through hole 31, soft siphunculus 5 and upper channel more than 12 persons on the disk 3, relend the suction that helps dust catcher dust is passed through the dust absorption passage sucking-off, reach pick-up performance at last.

The foregoing description is only for the usefulness that the utility model is described; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
