Description
Technical field
The utility model relates to a kind of positioner, particularly a kind of two hole concentric locating devices.
Background technology
Two traditional hole concentric locating devices are formed (seeing Fig. 1-3) by backstay 1, abutment sleeve 2 and base 3, abutment sleeve 2 is fixed on the base 3, backstay 1 passes needs two holes of location to enter abutment sleeve 2, and backstay 1 is threaded with abutment sleeve 2, with the purpose that reaches the location and clamp.Such structure is because the concentricity requirement of the locating surface of backstay 1 and abutment sleeve 2 and flank is all very high, and the processing technology difficulty is big; When operation, for the screw thread of not damaging, must carefully put into during operation, because threaded portion must all screw in and all withdraw from, operation inconvenience; And because it is big to screw power, in case take out difficulty behind the thread biting locking.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of two hole concentric locating devices that are easy for installation and removal.
The technical solution of the utility model is as follows: a kind of two hole concentric locating devices, comprise backstay, abutment sleeve and base, described abutment sleeve is made up of installed surface and the sleeve that passes the installed surface middle part, described abutment sleeve is fixed on the base, one end of described backstay is provided with lining and the nut corresponding with this lining, the other end is provided with stopping means, described stopping means is made up of connecting rod and locating part, described locating part is elongated, the length of described locating part is bigger than the diameter of connecting rod, one end of described connecting rod is connected on the backstay, the other end is connected the centre position of locating part, described sleeve lining is provided with the bar hole with locating part coupling, is positioned on the sidewall of the following sleeve of installed surface to have two breach corresponding with locating part.
Adopt technique scheme, one end of described backstay is provided with lining and the nut corresponding with this lining, the other end is provided with stopping means, stopping means is made up of connecting rod and locating part, during use, backstay is passed two holes that need to locate enter abutment sleeve, then keeper is revolved and turn 90 degrees, locating part is stuck in the corresponding breach,, just can locatees then with nut screwing clamping; Only need during taking-up nut is unclamped, backstay is revolved turn 90 degrees just and can easily take out.
In technique scheme: described nut is a hex nut.
In technique scheme: described locating part is the formed strips in the cylindrical both sides of cutting of a symmetry.
Beneficial effect: the utility model is reasonable in design, simple in structure, implement easily, and it is all very convenient to have operability, processing, a use.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Shown in Fig. 4-7, the utility model is by backstay 1, abutment sleeve 2 and base 3 are formed, one end of described backstay 1 is provided with lining 4 and the hex nut 5 corresponding with this lining 4, the other end is provided with stopping means, described stopping means is made up of connecting rod 6 and locating part 7, described locating part 7 is by the formed strip in the cylindrical both sides of cutting of a cylinder symmetry, both sides after being cut off form two parallel plane 7a on locating part 7, the length of described locating part 7 is bigger than the diameter of connecting rod 6, one end of described connecting rod 6 is connected on the backstay 1, the other end is connected the centre position of locating part 7, form two symmetrical boss 7b thus at the two ends of locating part 7, described abutment sleeve 2 is made up of installed surface 2a and the sleeve 2b that passes the installed surface middle part, described abutment sleeve 2 is fixed on the base 3, described sleeve 2b inwall is provided with the bar hole 8 with locating part 7 coupling, is positioned on the sidewall of the following sleeve 2b of installed surface 2a to have two breach corresponding with the boss 7b of locating part 79.
During use, two holes of backstay 1 being passed the needs location enter abutment sleeve 2, keeper 1 are revolved to turn 90 degrees then, and boss 7b is stuck in the corresponding breach 9, then hex nut 5 are tightened, and just can locate; Only need during taking-up hex nut 5 is unclamped, backstay 1 is revolved turn 90 degrees just and can easily take out.
The present invention is not limited in the specific embodiment, and described locating part 7 also can be cuboid etc.
