Abstract
An anti-run drill mainly comprises an anti-run protective sleeve, an outer cylinder, a drive chuck and a drill, wherein the drill is connected to the drive chuck which is connected to one end of the outer cylinder; one end of the anti-run protective sleeve is blocked in a slot composed of the outer cylinder and the drive chuck; after being transitionally connected, the other end of the anti-run protective sleeve is sleeved on the drill. The anti-run drill of the utility model has the advantages of simple structure and reliable connection; broken drills can be recovered, and the anti-run drill is suitable for working in deep hole.
Description
Technical field
The utility model relates to a kind of slip-off preventing drill bit, is applicable to the drill bit of high blast down-the-hole air hammer is protected.
Background technology
In bore operation, how quick, efficient, stable, economy becomes present urgency problem to be solved.
Old-fashioned rig is when creeping into, if drill bit is interrupted, breaking portion is stayed and is difficult in the hole take out, and is cancelled in the hole of being bored, and causes the increase of time and cost, causes great inconvenience to the user.
The utility model content
The purpose of this utility model is to overcome the deficiency of prior art and provides a kind of simple in structure, and is easy to use, connects reliably, conveniently breaking portion taken out of after drill bit is interrupted, and do not influence the slip-off preventing drill bit of hole quality.
The purpose of this utility model is achieved by following technical proposals:
A kind of slip-off preventing drill bit; comprise outer shell, card drill sleeve, drill bit; described drill bit is connected with described card drill sleeve; described card drill sleeve is screwed in described outer shell one end; comprise the slip-off preventing protective sleeve; one end of described slip-off preventing protective sleeve is installed on the described card drill sleeve, and an other end is fixed described drill bit.
In the utility model; one end inwall of described slip-off preventing protective sleeve is provided with screw thread; other end inwall is provided with slideway; the end of described slideway is provided with interior step; the end of thread spinning of described slip-off preventing protective sleeve is in the card drill sleeve outside; the slideway end of described slip-off preventing protective sleeve is sleeved on the described drill bit, makes that the outer step on the described drill bit is installed in the slideway of described slip-off preventing protective sleeve.
In the utility model, also be provided with the upper end grab that is installed in the groove of being formed by described outer shell and described card drill sleeve on the described slip-off preventing protective sleeve.
Owing to adopt above-mentioned scheme; slip-off preventing protective sleeve one end spinning is installed in the groove of being made up of described outer shell and described card drill sleeve in the card drill sleeve outside and by the upper end grab; the other end is sleeved on the described drill bit; make the outer step of drill bit be fixed in the slip-off preventing protective sleeve; when drill bit is interrupted; the trip of slip-off preventing protective sleeve is fixed the outer step of drill bit, takes the drill bit of fracture out of deep hole.
In sum, described utility model---a kind of slip-off preventing protective sleeve has simple in structurely, easy to use, connects reliably, the drill bit of fracture can be reclaimed, and be applicable to the deep hole operation.

State when Fig. 2 works for the slip-off preventing protective sleeve.
In the accompanying drawing 1,2,1---outer shell, 2---the card drill sleeve, 3---the slip-off preventing protective sleeve, 4---drill bit, 5---the card drill sleeve, 6---the slip-off preventing protective sleeve, 7---drill bit.
The specific embodiment
Below in conjunction with accompanying drawing, describe the specific embodiment of slip-off preventing protective sleeve in detail.
As described in Fig. 1,2; a kind of slip-off preventing drill bit; comprise outer shell 1, card drill sleeve 2, drill bit 4; described drill bit 4 is connected with described card drill sleeve 2; described card drill sleeve 2 is screwed in described outer shell 1 one ends; comprise slip-off preventing protective sleeve 3, an end of described slip-off preventing protective sleeve 3 is installed on the described card drill sleeve 2, and an other end is fixed described drill bit 4.
In the utility model; one end inwall of described slip-off preventing protective sleeve 3 is provided with screw thread; other end inwall is provided with slideway 6; the end of described slideway 6 is provided with interior step 5; the end of thread spinning of described slip-off preventing protective sleeve 3 is in card drill sleeve 2 outsides; the slideway end of described slip-off preventing protective sleeve 3 is sleeved on the described drill bit 4, makes that the outer step 7 on the described drill bit 4 is installed in the slideway 6 of described slip-off preventing protective sleeve 3.
In the utility model, also be provided with the upper end grab that is installed in the groove of being formed by described outer shell 1 and described card drill sleeve 2 on the described slip-off preventing protective sleeve 3.
The utility model operating principle is as follows: as shown in Figure 1; to block drill sleeve 2 by the spline connection is sleeved on the drill bit 4; connect slip-off preventing protective sleeve 3 spinnings on card drill sleeve 2 and be sleeved on outside the drill bit 4 by the screw thread transition; the outer step of drill bit 4 is installed in the slideway 6 of slip-off preventing protective sleeve 3; as shown in Figure 2; when the fracture of drill bit 4 middle parts, the part drill bit 4 of fracture is connected with outer step by interior step with slip-off preventing protective sleeve 3, and drill bit can not stayed in the deep hole when carrying brill.
