Abstract

The utility model, which provides one kind, can keep permanent sharp electric hammer diamond bit; including installing handle; one end of the installing handle is also convexly equipped with a rectangular body running core; and the longitudinal center line of the rectangular body running core and the longitudinal center line of the installing handle are overlapped; the four edges that the rectangular body running core is parallel to longitudinal center line are convexly equipped with a screening glass respectively, and four screening glass also extend to and are connected with one end of the installing handle.Diamond bit described in the utility model is using the rectangular body running core as work department; it ensure that intensity; prevent impact fracture; firm and durable, simultaneously because four screening glass are easier to wear than relatively thin, compared to the rectangular body running core; so that abrasion first occurs in four screening glass; therefore the effective work department of holding that when in use can be permanent is rectangular body running core, to ensure that sharp, the raising working efficiency that diamond bit described in the utility model can be permanent.

Description

It is a kind of to keep permanent sharp electric hammer diamond bit

[technical field]

The utility model relates to chisels, especially a kind of to keep permanent sharp electric hammer diamond bit.

[background technique]

It in building trade, is generally dug on cement wall or floor, due to the wall after the solidification of cement material Or floor is very hard, and diamond bit generally carries out on the electric hammer to excavating work, mainly diamond bit carries out reciprocal telescopic impact when work, It is dug.Existing diamond bit generally comprises installing handle and work department, and work department is arranged in one end of installing handle, and existing diamond bit Work department be generally pyramid type, after a period of use, the tip of pyramid type work department is easy to wear, the rate of wear Fastly, so that diamond bit work department becomes arc-shaped, thus rust, simultaneously because after becoming arc, effective work area very little is reduced Working efficiency, on the other hand, the conical work department after abrasion, which carries out polishing, to be made it again and becomes sharp, in this way due to grinding It is fast to damage speed, so that polishing frequency is very high, wastes time, maintenance cost is high, and since cement is very hard, if work department is very Point be easy to cause work department that impact fracture occurs, influences service life when then digging.

[utility model content]

To overcome defect existing for existing equipment, the utility model lies in that providing one kind can keep permanent sharp, firm resistance to Electric hammer diamond bit substantially increases the working efficiency of cutting.

The utility model is realized in this way: one kind can keep permanent sharp electric hammer diamond bit, including installing handle, described One end of installing handle is also convexly equipped with a rectangular body running core, and the longitudinal center line and the installing handle of the rectangular body running core Longitudinal center line be overlapped, the four edges that the rectangular body running core is parallel to longitudinal center line are convexly equipped with a screening glass respectively, And four screening glass also extend to and are connected with one end of the installing handle, include straight line portion and taper per the screening glass The outer diameter of end, outer diameter and the installing handle that the straight line portion of four screening glass is formed is equal.

Further, the length of the rectangular cross section of the rectangular body running core is 8mm, width 5mm.

Further, the range of the length L of the rectangular body running core is 5cm≤L≤6cm.

Further, per the screening glass with a thickness of 1.3mm.

Utility model has the advantages that the utility model, which provides one kind, can keep permanent sharp electric hammer diamond bit, adopt It uses the rectangular body running core as work department, ensure that intensity, prevent impact fracture, firm and durable, simultaneously because four A screening glass is easier to grind than outside relatively thin and positioned at the rectangular body running core compared to the rectangular body running core Damage, so that abrasion first occurs in four screening glass, therefore the effective work department of holding that when in use can be permanent is rectangular Body running core, to ensure that sharp, the raising working efficiency that diamond bit described in the utility model can be permanent.

[Detailed description of the invention]

The utility model is further described in conjunction with the embodiments with reference to the accompanying drawings.

Fig. 1 is the structural schematic diagram of diamond bit described in the utility model.

In figure: 1, installing handle；2, rectangular body running core；3, screening glass；31, straight line portion；32, tapered end.

[specific embodiment]

Refering to Figure 1, the utility model, which provides one kind, can keep permanent sharp electric hammer diamond bit, including installing handle 1, one end of the installing handle 1 is also convexly equipped with a rectangular body running core 2, and the longitudinal center line of the rectangular body running core 2 and The longitudinal center line of the installing handle 1 is overlapped, and the rectangular body running core 1 is parallel to the four edges difference projection of longitudinal center line There is a screening glass 3, and four screening glass 3 also extend to and are connected with one end of the installing handle 1, per the screening glass 3 Including straight line portion 31 and tapered end 32, outer diameter that the straight line portion 31 of four screening glass 3 is formed and the installing handle 1 it is outer Diameter is equal.In use, diamond bit described in the utility model is mounted on electric hammer by the installing handle 1, using described rectangular Body running core 2 is used as work department, ensure that intensity, prevents impact fracture, firm and durable, simultaneously because four protections Piece 3 is easier to wear than surrounding relatively thin and positioned at the rectangular body running core 2 compared to the rectangular body running core 2, so that mill Damage first occurs working end can be kept tapered always, therefore guarantor that when in use can be permanent in four screening glass 3 Holding effective work department is the rectangular body running core 2, so that ensure that diamond bit described in the utility model can be permanent is sharp, Improve working efficiency.

In specific implementation, a preferred embodiment: the length of the rectangular cross section of the rectangular body running core 2 is 8mm, Width is 5mm, can not only guarantee sharpness but also can be with proof strength.

The range of the length L of the rectangular body running core 2 is 5cm≤L≤6cm.

Per the screening glass 3 with a thickness of 1.3mm.

Certainly in other embodiments, there can also be other sizes, here no longer illustrate.

The utility model has the beneficial effects that holding that can be permanent is sharp, and firm and durable, working efficiency can be improved.

Although those familiar with the art answers the foregoing describe specific embodiment of the present utility model Working as understanding, we are merely exemplary described specific embodiment, rather than for the limit to the scope of the utility model Fixed, those skilled in the art modification and variation equivalent made by the spirit according to the utility model all should Cover in the scope of the claimed protection of the utility model.
