Embodiment
For making the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with specific embodiment, and with reference to accompanying drawing, the utility model is further described.
It should be noted that, in the utility model embodiment, the statement of all uses " first " and " the 2nd " is all the parameter in order to the entity or non-equal distinguishing two same names non-equal, visible " first " " 2nd " only convenience in order to state, should not be construed as the restriction to the utility model embodiment, this is illustrated by subsequent embodiment no longer one by one.
The embodiment of the utility model Portable X-ray machine laser locating apparatus, as shown in Figure 2, comprise hollow base 1 and three laser beam emitting devices 2, the hollow part of hollow base 1 is passed for X-ray, and radiation emanation window a (such as Fig. 1) and hollow base medullary ray c2 that hollow base 1 is fixed on X-ray machine 0 overlap with X-ray medullary ray c1.
As shown in Figures 2 and 3, three laser beam emitting devices 2 etc. are arranged at intervals in hollow base 1 outside circumference, thus form the annular array taking hollow base medullary ray c2 as axle, and the laser beam c3 transmit direction of each laser beam emitting device 2 is equal with hollow base medullary ray c2 angle, the joint M of three laser beam c3 is on hollow base medullary ray c2 as can be seen here.
Laser beam emitting device 2 can be fixedly connected with hollow base 1, and now joint M fixes a bit. Owing to hollow base medullary ray c2 overlaps with X-ray medullary ray c1, therefore joint M is on X-ray medullary ray c1, so only need to adjust angle and the position of X-ray machine 0, three laser beam c3 irradiating three somes formation equilateral triangles of position projection and are reduced gradually, until joint M appears at the position needing to irradiate, now can judge that X-ray medullary ray c1 is perpendicular to this and needs the position irradiated surperficial, thus realize accurately location.
Further, laser beam emitting device 2 can also be flexibly connected with hollow base 1, preferably, hollow base 1 comprises fixing base 101 and central movable disk 102, fixing base 101 is fixed on the radiation emanation window a (such as Fig. 1) of X-ray machine 0, the radiation emanation window a that central movable disk 102 is arranged at X-ray machine 0 is outside and axially fixing with fixing base 101, and now central movable disk 102 can rotate around hollow base medullary ray c2 relative to fixing base 101.
