Description

A kind of multi-functional durable sand frame

Technical field

The utility model relates to the polisher on wall face in building decoration field, especially a kind of multi-functional durable sand frame.

Background technique

The ancillary equipment that sand frame is polished as metope during decoration is applied quite extensively in our daily lifes, existing Some sand framves are usually to install a torque spring and interspersed torque spring in the side of iron clamp piece on the device of burning into sand paper Axis is not secured with nuts without screw, and design is not rigorous enough, often will appear clamping plate after the time is long and deviates toward one side, makes Sand paper is fixed built on the sand, polish metope when the case where will appear sand paper displacement, in addition holds when polishing inner corner trim after clamping plate offset Easily occur scratching the effect of metope, while after the fixed sand paper in bottom of sand frame, sand frame side can expose the side of sand paper, and polishing exempts to paint When door pocket, switch enclosure etc. should not scratch the edge metope of object, the side of the sand paper can all scratch the object, polish small moulding or When small articles, it is especially inconvenient that traditional sand frame can be used, those sand framves of especially polishing stretch the place that do not enter, increase work The difficulty of construction of people, working efficiency are also very low.

Summary of the invention

The purpose of this utility model is to provide for a kind of multi-functional durable sand frame.

In order to achieve the above objectives, the utility model is implemented according to following technical scheme:

A kind of multi-functional durable sand frame, it is characterised in that: including rectangular pedestal and the handle being set on pedestal, institute The both ends for stating pedestal are respectively provided with the clamping device for clamping sand paper, and the bottom of the pedestal is equipped with hard foam layer, described Clamping device includes the clamping plate that portion on the base is arranged, and clamping plate both ends back is respectively equipped with clamping plate connecting hole, the clamping plate It is set between the pedestal there are two torque spring and a spring shaft, the perforative connecting cleat connecting hole of the spring shaft and two A torque spring is simultaneously detachably mounted on the pedestal by spring axle bed, and one end diameter of the spring shaft is greater than torsion The diameter of spring, the other end of the spring shaft have been connected through a screw thread nut, and the handle upper end is equipped with groove, the groove Interior to be equipped with Z shape steel plate bending part, the fixed sand paper in the right end bottom of the Z-shape steel plate bending part, the handle inside, which is equipped with, to be used for Z-shape steel plate bending part is adsorbed on the magnet in groove.

Further, several perforative apertures are equipped on the pedestal and hard foam layer.

Further, the both ends of the pedestal are respectively equipped with convex edge, and the convex edge is matched with clamping plate to clamp sand paper.

Further, the handle includes cross bar and two vertical poles, and cross bar and vertical pole are in 90 degree.

Further, the bottom of the clamping plate is zigzag.

Compared with prior art, the multi-functional durable sand frame of the utility model is compared with traditional sand frame, using double torsion The structure of spring solves clamping plate offset and causes to scratch inner corner trim when polishing metope for a long time using being not in that clamping plate deviates Problem, spring shaft one end of the multi-functional durable sand frame of the utility model, which is adopted, to be secured with nuts, and is not in torque spring toward one end The phenomenon that sliding, structure is more stable, clamping plate uniform force, fixes sand paper more smooth secured, sand paper will not be run in use Partially, the bad problem of polishing metope effect is avoided, in addition the handle upper end of the multi-functional durable sand frame of the utility model is equipped with One groove, groove is interior to be equipped with a Z-shape steel plate bending part, and flocking sand paper, the Z-shape steel are pasted in the right end bottom of steel plate bending part Plate bending part can stretch the place that do not enter for polish small moulding, small articles or sand frame, and worker can directly take out the Z-type Steel plate bending part is used to polish, simple and practical and can improve work task efficiency, when polishing metope, inevitably will appear dust Little particle is fallen between sand paper and hard foam layer, can seriously affect the flatness of polishing metope in this way, the utility model Perforative on multi-functional durable sand frame pedestal and hard foam layer to be equipped with several apertures, dust little particle can be in sand frame polishing metope Power effect under shaked out by sieve.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only It is some embodiments of the utility model, for those of ordinary skill in the art, before not making the creative labor property It puts, is also possible to obtain other drawings based on these drawings.
