Description

A kind of small sand frame of suitable polishing small space

Technical field

The utility model relates to the polisher on wall face in building decoration field, especially a kind of suitable polishing small space Small sand frame.

Background technique

In building decoration construction, the polishing of metope is essential working procedure, is commonly to apply with sand paper polishing Work method usually sticks on sand frame with sand paper and polishes, sand frame is as decoration process to improve grinding efficiency and polishing quality The ancillary equipment of middle metope polishing, using quite extensively in our daily lifes, traditional sand frame torsion spring sections are general It being secured with nuts using one and not, design is not rigorous enough, and it often will appear clamping plate after the time is long and deviated toward one side, so that Sand paper is fixed built on the sand, polish metope when the case where will appear sand paper displacement, be in addition easy when polishing inner corner trim after clamping plate offset 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, paintless door of polishing When set, switch enclosure etc. should not scratch the edge metope of object, the side of the sand paper can all scratch the object, increase the construction of worker Difficulty, working efficiency is also very low, and traditional sand frame bottom is using hard foam layer as bottom, after a period of use, hard Four corner angle of spongy layer can be worn, polish inner corner trim when will appear that compactness is poor, the bad situation of grinding effect.

Summary of the invention

The purpose of this utility model is to provide for a kind of small sand frame of suitable polishing small space.

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

A kind of small sand frame of suitable polishing small space, including bottom plate and the handle being fixed on bottom plate, the bottom plate Bottom silicane rubber plate or butyl rubber plate are pasted with by all-purpose adhesive, bottom plate both ends top is respectively equipped with clamping device, The rectangular triangular prism shape of clamping device, fixed plate and triangular jaws including bottom, the both ends bottom of the clamping device Portion is respectively equipped with plastic bearing, and the fixed plate is fixed on bottom plate by four screws, and the screw at both ends runs through plastics Bearing, the plastic bearing are flushed with bottom plate both sides.

Further, the bottom plate is for plastic material and with a thickness of 2mm, the thickness of the silicane rubber plate or butyl rubber plate For 2mm.

Further, rotatable pressing handle is connected among the back of the clamping device.

Further, the end of the triangular jaws is serrated.

Compared with prior art, the small sand frame of the suitable polishing small space of the utility model, with traditional sand frame phase Compare, four plastic bearings are arranged in the surrounding of bottom plate, when polishing some corners, for example, metope inner corner trim and door pocket joint, The inner corner trim of switch enclosure, bearing can be bonded the side of inner corner trim or door pocket, mitigate the side abrasion of sand frame, and compactness is higher, but also Paintless door set or switch enclosure will not be scratched, worker is time saving and energy saving with the rotation of bearing when polishing pushes and pulls sand frame； The utility model also uses elastomeric skin layer, and perhaps silicane rubber plate replaces traditional hard foam layer elastomeric skin layer or silicane rubber plate It is more preferable compared to hard foam layer elasticity, it is restorative strong, strengthen the intensity of corner angle, corner angle are not damaged, polish inner corner trim when compactness Height, grinding effect is good, improves work task efficiency.

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.

Fig. 1 is the structural schematic diagram of the utility model；

Fig. 2 is the side structure schematic view of the utility model；

Fig. 3 is the overlooking structure diagram of the utility model.

Specific embodiment

The utility model will be further described below with reference to the accompanying drawings and specific embodiments, in the signal of this utility model Property embodiment and explanation be used to explain the utility model, but be not intended to limit the scope of the present invention.

As shown in Figure 1, 2, 3, a kind of small sand frame of suitable polishing small space, including bottom plate 1 and be fixed on bottom plate Handle 2, it is characterised in that: the bottom of the bottom plate 1 is pasted with silicane rubber plate or butyl rubber plate 3 by all-purpose adhesive, described Bottom plate 1 is plastic material and with a thickness of 2mm, the silicane rubber plate or butyl rubber plate 3 with a thickness of 2mm, using elastomeric skin layer Perhaps silicane rubber plate replaces traditional hard foam layer elastomeric skin layer or silicane rubber plate more preferable compared to hard foam layer elasticity, It is restorative strong, strengthen the intensity of corner angle, corner angle are not damaged, polish inner corner trim when compactness it is high, grinding effect is good, improves worker Working efficiency；The 1 both ends top of bottom plate is respectively equipped with clamping device 4；As shown in figure 3, in the back of the clamping device 4 Between be connected with rotatable pressing handle 8, the rectangular triangular prism shape of the clamping device 4, fixed plate 5 and triangle including bottom The end of clevis plate 6, the triangular jaws 6 is serrated, and the both ends bottom of the clamping device 4 is respectively equipped with plastic bearing 7, the fixed plate 5 is fixed on bottom plate 1 by four screws, and the screw at both ends runs through plastic bearing 7, the plastic shaft 7 are held to flush with 1 both sides of bottom plate, four plastic bearings are arranged in the surrounding of bottom plate, when polish some corners, for example, metope inner corner trim and The joint of door pocket, switch enclosure inner corner trim, bearing can be bonded the side of inner corner trim or door pocket, mitigate the side abrasion of sand frame, fitting Du Genggao, but also paintless door set or switch enclosure will not be scratched, worker is when polishing pushes and pulls sand frame, with turning for bearing It is dynamic, it is time saving and energy saving.

The limitation that the technical solution of the utility model is not limited to the above specific embodiments, all skills according to the present utility model The technology deformation that art scheme is made, each falls within the protection scope of the utility model.
