The bottom deck assembly being applied in sanderTechnical field
The present invention relates to a kind of sanding and polishing instrument parts, be specifically related to a kind of bottom deck assembly being applied in sander.
Background technology
When workpiece being polished or polishing, commonly use the sanding devices such as sander, the most hand-held skin grinder, because it is convenient, flexible, receive the welcome of users.Sander is positioned at casing for providing the driving means of driving force, and driving means is connected with working plate by transmission device, is pasted with the abrasive material such as sand paper in the bottom surface of base plate.During work, driving means typically drives bottom deck assembly eccentric motion, attach the sand paper with bottom deck assembly will corresponding sports, working face is polished, thus is allowed to smooth.Existing sander base arrangement is complicated, changes sand paper inconvenience.
Summary of the invention
The technical problem to be solved in the present invention is the defect overcoming prior art, it is provided that a kind of bottom deck assembly being applied in sander, this bottom deck assembly simple in construction, changes sand paper convenient.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
nullA kind of bottom deck assembly being applied in sander，Including base plate setting up and down and base pad，There is on described base plate sand paper folder，Described sand paper folder includes two be oppositely arranged，Each described sand paper presss from both sides the rigid element being formed in one，Described base plate one side end has the first installing hole，Base plate homonymy the other end has position-limit mechanism，Described sand paper folder includes the clamping part being positioned between described first installing hole and described position-limit mechanism，The opening press section extended to base plate neighbour side with self-limiting mechanism，Described clamping part is downward-sloping，Described opening press section is upturned，Clamping part has clamping free end，Opening press section has pressing free end，Clamping free end makes sand paper folder be connected with base plate torsion in inserting the first installing hole，Pin downwards pressing free end，Clamping part is upturned，Now，Sand paper can be removed or install，Time not to sand paper folder force，Clamping part clamps sand paper.
Preferably, described position-limit mechanism include for described sand paper folder through groove and along recess sidewall arrange fixing hole, fixing hole is connected with the first screw.
Preferably, also there is bottom plate gasket between described base plate and base pad.
Preferably, described base plate, bottom plate gasket, base pad are respectively provided with dedusting hole one to one.
Preferably, described base plate, bottom plate gasket and base pad connect by some second installing holes and the second screw are fixing.
Preferably, described base plate center has main shaft connecting hole.
Bottom deck assembly alleged by the present invention is flat board sand assembly, is installed on bottom sander, and preferably base plate is the flat board sand of rectangle.
The beneficial effect that the present invention is reached:
The bottom deck assembly simple in construction of the present invention, install, dismantle during sand paper convenient and swift, low cost of manufacture；Sand paper two ends are clamping fixed by the sand paper being oppositely arranged, and pin downwards the pressing free end of sand paper folder, and clamping part is upturned, and now can install, dismantles or adjust sand paper, and when the pressing free end to sand paper folder does not exerts a force, sand paper folder is in the clamped condition to sand paper.

Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.Following example are only used for clearly illustrating technical scheme, and can not limit the scope of the invention with this.
nullAs Figure 1-3，A kind of base plate 33 assembly being applied in sander，Including base plate 33 setting up and down and base pad 41，There is on base plate 33 sand paper folder 35，Sand paper folder 35 includes two be oppositely arranged，The rigid element that each sand paper folder 35 is formed in one，Base plate 33 1 side end has the first installing hole 332，Base plate 33 homonymy the other end has position-limit mechanism，Sand paper folder 35 includes the clamping part 353 between described first installing hole 332 and described position-limit mechanism，The opening press section 354 extended to the adjacent side of base plate 33 with self-limiting mechanism，Clamping part 353 is downward-sloping，Opening press section 354 is upturned，Clamping part 353 has clamping free end 352，Opening press section 354 has pressing free end 351，Clamping free end 352 makes sand paper folder 35 be connected with base plate 33 torsion in inserting the first installing hole 332，Pin downwards pressing free end 351，Clamping part 353 is upturned，Now，Sand paper can be removed or install，Time not to sand paper folder 35 force，Clamping part 353 clamps sand paper.
Position-limit mechanism includes the groove 333 that sand supplying folder 35 passes and the fixing hole 334 arranged along groove 333 sidewall, and fixing hole 334 is connected with the first screw 34-1.To 353 position-limiting actions of clamping part, ensure the stability of sand paper folder when clamping part 353 is lifted.
The base plate 33 of the present embodiment is rectangular base plate 33, and base pad 41 is also to have bottom plate gasket 40 between sponge base pad, and base plate 33 and base pad 41.Being respectively provided with dedusting hole one to one in base plate 33, bottom plate gasket 40, base pad 41, dedusting hole includes the 331, second dedusting hole, the first dedusting hole 401 and the 3rd dedusting hole 411 laying respectively in base plate 33, bottom plate gasket 40 and base pad 41.Base plate 33, bottom plate gasket 40 and base pad 41 connect by some second installing holes and the second screw 34-2 are fixing.Base plate 33 center has main shaft connecting hole.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, on the premise of without departing from the technology of the present invention principle; can also make some improvement and deformation, these improve and deformation also should be regarded as protection scope of the present invention.
