Description

a sand wall

technical field

The utility model relates to a construction tool, in particular to a wall sander for grinding walls.

Background technique

In house decoration, the walls and ceilings usually need putty layer, and then brush or spray paint or paste wallpaper. Therefore, the leveling and smoothness of the putty layer or the follow-up process has a great influence, but the putty layer is generally scraped by workers during decoration, and may be uneven. At present, ordinary people use emery cloth or sandpaper to manually sand or use a kind of simple and easy sand wall device to sand. In order to solve the above problems, the authorized announcement number is CN202846286U, a sand wall device whose structure is, a sandpaper fixing plate, a left clip, a right clip, the left clip is fixed on the left side of the back of the sandpaper fixing plate, and the right clip is fixed on the sandpaper fixing plate. The right side of the back; it is characterized in that: the middle part of the back of the sandpaper fixed plate is fixedly connected with a semi-rotary connector, and the semi-rotary connector is inserted and fixedly connected with the upper end of the support rod. But it still has shortcomings: it cannot effectively polish the wall surface, and the efficiency is low, and the sandpaper is not fixed tightly.

Contents of the invention

The problem to be solved by the utility model is: to provide a sand wall device, which can effectively scrape and smooth the putty layer on the wall, has high working efficiency, simple structure and convenient operation.

The technical scheme of the utility model is:

A sand wall device, comprising a planer, a fixed plate, sandpaper, a handle, the handle is located on the top surface of the fixed plate and rigidly connected with it, it is characterized in that the front and rear ends of the bottom surface of the fixed plate are provided with a reference convex table surface, and the middle part is The sandpaper fits the concave surface and the fixed concave surface of the planer. There are threaded holes for fixing the planer on the fixed concave surface of the planer. On the left and right of the fixed concave surface of the planer are respectively rectangular chip removal holes and sandpaper pressing holes. On the left side of the sandpaper pressing hole and the handle The right side is respectively provided with a pair of support columns, which are provided with rotating shaft holes; also includes a pressing shaft, which is provided with an eccentric shaft hole, and the rotating shaft passes through the rotating shaft hole and the eccentric shaft hole to connect the pressing shaft and the supporting column together ; The planer is provided with two waist-shaped countersunk holes, and the planer is fixed on the fixed concave surface of the planer with screws through the threaded holes and the countersunk holes; after the sandpaper and the planer are installed on the fixed plate, the bottom surface of the planer and the sandpaper work The face and the datum boss face are on the same plane.

The beneficial effects of the utility model are: after the planer and sandpaper are fixed on the fixed plate, when grinding the wall, the wall is polished very smooth with the reference convex surface on the fixed plate as the reference, and the previous planer will first The part of the wall surface higher than the reference surface is planed off at one time, which increases the efficiency of smoothing the wall surface, and the final sandpaper will smooth the planed part.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

As shown in Figures 1 to 4, a sand wall device of the present invention includes a planer 3, a fixed plate 7, sandpaper 8, and a handle 13. The handle 13 is located on the top surface of the fixed plate 7 and is rigidly connected to it. It is characterized in that the The front and rear ends of the fixed plate 7 (length 22cm, width 9cm, thickness 1cm) are provided with a reference convex surface 1 (width 8mm), and the middle part is a sandpaper-fit concave surface 14 (the depth is the thickness of ordinary sandpaper) and a planer fixed concave surface 16 (depth 5mm), on the fixed concave surface 16 of the planer, there is a threaded hole 15 for fixing the planer 3, and on the left and right of the fixed concave surface 16 of the planer are respectively rectangular chip removal holes 2 and sandpaper pressing holes 6, and the sandpaper pressing holes 6 The left side and the right side of the handle 13 are respectively provided with a pair of support columns 9, and the middle part 0 is provided with a shaft hole 12; it also includes a pressing shaft 10, which is provided with an eccentric shaft hole 17, and the shaft 11 passes through the shaft hole 12 and the eccentric The shaft hole 17 connects the pressing shaft 10 with the support column 9; the planer 3 (the blade angle is 38°~40°) is provided with two waist-shaped countersunk holes 5, and the screw 4 passes through the threaded hole 15 and the countersunk hole 5 fix the planer 3 on the fixed concave surface 16 of the planer; after the sandpaper 8 and the planer 1 are installed, the bottom surface of the planer 3, the sandpaper working surface and the reference convex table surface 1 are on the same plane; the planer 3 can use 45 #Steel, all the other main parts can be made of plastics, wherein the threaded hole 15 on the fixed plate 7 and the reference boss surface 1 adopt a metal insert mode to increase strength and wear resistance.

Instructions for the use of the sand wall device: firstly grind the blade surface of the planer 3 to a suitable angle, then use the screw 4 to fix the planer 3 on the fixed plate 7 through the threaded hole 15, and attach the back of the sandpaper 8 to the sandpaper On the concave surface 14, pass one end of the sandpaper 8 from the bottom surface successively through the gap between the sandpaper pressing hole 6 and the pressing shaft 10 and the fixing plate 7, and rotate the pressing shaft 10 to compress the sandpaper on the fixing plate 3, and then use the same Compress the other end of the sandpaper 8 on the fixed plate 3 in the same way, hold the handle 13 with your hand, and grind it on the wall back and forth.
