Abstract

The utility model discloses a wall surface sander, which comprises a bottom plate, a handle connector positioned at the centre of the upper surface of the bottom plate, a handle connected with the handle connector, a foaming layer pasted on the lower surface of the bottom plate, a nylon agraffe layer pasted on the foaming layer, as well as polishing material connected with the nylon agraffe layer, wherein the handle is composed of a retractable bar and a fixed bar, and the fixed bar is connected with the handle connector on the bottom plate. Because the utility model adopts the method of directly bonding the nylon agraffe layer with the polishing material, even force on the working surface of the sander is ensured, thereby the wall can be polished more smoothly, simultaneously, because the handle adopts the retractable bar structure, the length of which can be adjusted, the utility model can be suitable for different working environments, and avoid the potential personal danger caused by the working at height of the operators.

Description

Sander

Technical field

The utility model relates to a kind of building decoration instrument by hand, more particularly relates to the sander that a kind of polishing wall surface is used.

Background technology

China's utility model patent numbers 91206869.8 discloses a kind of board-like sander, it is simple in structure, rationally, make the utilization rate of emery cloth be improved, still, because emery cloth directly is attached to the spongy layer top, two is pressed under the press plate mechanism after turnover, combination between emery cloth and the spongy layer is easy to produce partial aperture like this, makes whole emery cloth working face discontinuity, thus influence polishing quality; Simultaneously, because the handle in this patent is a loop configuration, though conveniently control, need by ladder or stool when polishing metope higher, the workman may bring potential safety hazard because of aerial work like this.

Summary of the invention

The utility model is not good enough in order to solve in the above-mentioned patent sander polishing quality, the problem of aerial work personal dangerousness increase simultaneously, a kind of improved sander is provided, the technical scheme that it adopts is: a kind of sander, comprise base plate, and be positioned at the handle connector of plate upper surface center, the handle that is connected with the handle connector, be attached to the foaming layer on the base plate lower surface, be attached to the velcro layer in the foaming layer, and the abrasive material that is connected with the velcro layer.

Described plate upper surface two ends also are provided with the geometrical clamp that is used for fixing abrasive material.

Be provided with reinforcement between described handle connector and the geometrical clamp.

Described handle connector is a universal joint, and it is connected on the base plate by a resilient key.

Described handle is made up of a telescopic rod and a fixed bar, and wherein fixed bar is connected with handle connector on the base plate.

The beneficial effects of the utility model are:

Because the utility model has adopted the direct bonding abrasive material of velcro layer, make the working face stress equalization of sander, thereby the polishing effect is more smooth, simultaneously, because handle adopts the expansion link structure, can regulate length, therefore applicable to different working environments, the potential Personal Risk who has also avoided operating personnel's ascend operation to be brought.

Description of drawings

Fig. 1 is the utility model structural front view;

Fig. 2 is the utility model structure vertical view.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Referring to Fig. 1-Fig. 2, a kind of sander of the utility model, comprise: comprise base plate 1, be positioned at the handle connector 5 of base plate 1 upper surface center, the handle 6 that is connected with handle connector 5, be attached to the foaming layer 2 on base plate 1 lower surface, be attached to the velcro layer 3 in the foaming layer 2, and the abrasive material 4 that is connected with velcro layer 3.

In the present embodiment:

Described base plate 1 upper surface two ends also are provided with two geometrical clamps 7 that are used for fixing abrasive material 4.

Described handle connector 5 is a universal joint, and it is connected on the base plate by a resilient key 8.

In order to prevent that handle connector 5 is pressed onto geometrical clamp 7 in the practical operation, between base plate 1 upper surface handle connector 5 and geometrical clamp 7, also be provided with reinforcement 9.

Described handle 6 is made up of a telescopic rod 61 and a fixed bar 62, and wherein fixed bar 62 is connected with handle connector 5 on the base plate 1.

Because the utility model has adopted the direct bonding abrasive material of velcro layer, make the working face stress equalization of sander, thereby the polishing effect is more smooth, simultaneously, because handle adopts the expansion link structure, can regulate length, applicable to different working environments, the potential Personal Risk who has also avoided operating personnel's ascend operation to be brought.Therefore the utility model can be widely used in the building decoration industry.
