Description

A kind of grooving tool

Technical field

The utility model relates to a kind of construction decoration instrument of building, particularly relates to a kind of grooving tool.

Background technology

Decoration for building construction is fitted up, and its hydropower installation is one capital project, and the instrument that the installation of its water power umbilical of existing hydropower installation typically uses is that the drill hammer being exclusively used in boring carries out excavation water power umbilical built-in groove to wall etc.This buildings such as wall that carry out are used to slot, due to the instrument that it is not for slotting, this drill hammer impacts body of wall when slotting by drill vibration and outputs groove on the one hand, very large to the destructive power of body of wall, and power consumption is large especially, the labour intensity of workman is also very large; On the other hand its width and the degree of depth are all than the wide many of actual needs with firmly get many usually for its groove outputed, and this all causes very large impact to the engineering of follow-up pipe laying cable, and one is the increase in its workload, and two is the recovering qualities affecting metope; And its inefficiency, construction quality is poor, and its degree of depth outputed of same groove and width differ, and relative construction cost is high.

Utility model content

The purpose of this utility model is that the deficiency existed for above-mentioned prior art is carried, and provides a kind of grooving tool.This grooving tool is simple and reasonable for structure, easy to use, and efficiency of construction is high, and construction quality is high, on by the construction impact of object and destructiveness little.

The technical scheme of grooving tool of the present utility model comprises handle bar and corresponding cutter head, and described cutter head comprises the slot type chisel head being connected to described handle bar, and its slot type chisel head is to curving in axis one angle of described handle bar.

The diapire of the groove of described slot type chisel head is curved on its cross section.

Described slot type chisel head is 5-40 degree relative to its angle of bend of handle bar.

One end that the groove depth of described slot type chisel head is connected with handle bar from it is deepened gradually toward edge of a knife one end.

The notch lopsidedness of edge of a knife end face from the diapire side of its groove along drilling direction toward groove of described slot type chisel head, in skewed on the corresponding lateral view being formed in slot type chisel head.

Described slot type chisel head is a triangle or asymmetric trapezoidal shape on the lateral view of its groove.

Described its groove of slot type chisel head is expanded gradually along edge of a knife direction.

The two lateral walls face of described its groove of slot type chisel head from its diapire toward notch direction in opening shape laterally.

The described angle that it opens is 0-45 degree.

By the metal plate of a corresponding trapezoidal shape or triangle, bending or bending is formed described slot type chisel head.

Because it is extremely reasonable, the structure of science forms grooving tool of the present utility model, it has high efficiency of construction, the quality of the groove that fluting speed is fast, output is good, arbitrarily can output the groove of the various degree of depth, width and different camber easily, and the degree of depth of the basic groove with needing of the length and width size of the groove outputed and stand out are seldom, little to the destructiveness of body of wall, construction noise is little, fluting saves time, laborsaving, power saving, and labor strength and working environment have the improvement of essence.

Detailed description of the invention

In order to understand the technical solution of the utility model further, by following examples, the utility model is described in further detail by reference to the accompanying drawings.

As Figure 1-5.The grooving tool of this example comprises handle bar 1 and is connected to the slot type chisel of handle bar 1 first-class.The free end of its handle bar 1 arranges the square connecting portion 4 in being connected with corresponding drive unit.The diapire of the groove of slot type chisel head 2 (i.e. diapire outside wall surface or diapire outside wall surface and internal face) 17 is curved on its cross section.

Axis one angle of slot type chisel head 2 to curving in handle bar 1, in this example, slot type chisel head 2 is 10-30 degree relative to its angle of bend 5 of handle bar 1.

The edge of a knife 3 end face of slot type chisel head 2 from the side, diapire face 17 of the groove 9 of slot type chisel head 2 along fluting drilling direction toward the notch lopsidedness of groove 9, be formed in slot type chisel head 2 relative on the lateral view of groove in skewed (or inclined plane), its angle 7 tilted can be 10-35 degree.

The degree of depth 8 of the groove 9 of slot type chisel head 2 is deepened toward the edge of a knife 3 one end gradually from one end that it is connected with handle bar 1, makes the wall of the two lateral walls 12 of the groove 9 of slot type chisel head 2 be the triangle be similar to or an asymmetric trapezoidal shape.Slot type chisel head 2 can be made up of the alloy plate bending of a corresponding triangle or asymmetric trapezoidal shape or bending.

The wall of the two lateral walls 12 of its groove 9 of slot type chisel head 2 expands open-shaped notch from its groove 9 diapire laterally toward groove 9 notch direction, and the angle 6 that it opens is 5-15 degree.

In another embodiment of the utility model, as shown in Figure 6, the wall of the two lateral walls 12 of its groove 9 of slot type chisel head 2 expands the angle 6 of opening from its groove 9 diapire laterally toward groove 9 notch direction is 0 degree.Namely its groove is wide to notch from bottom.All the other structures of this example etc. can with above-described embodiment roughly the same.

In the utility model again an embodiment, the groove of its slot type chisel head is expanded gradually along edge of a knife direction, makes slot type chisel head form a trumpet-shaped slot type chisel head.Its handle bar of the utility model can be square or circular etc.

Above-described embodiment is only the prominent example of application technical solutions of the utility model, and not detailed description of the invention of the present utility model is exhaustive, and other modified products based on the technical solution of the utility model all belong to protection scope of the present invention.
