Description
Technical field
The utility model is related to medical instruments field, more particularly to a kind of X-ray half-value layer test bracket.
Background technology
X-ray half-value layer refers to the substance thickness that X-ray intensity is attenuated to required for the half of initial value, and it reflects X
The penetration capacity of ray.The half-value layer of X-ray production apparatus has regulation in national standard, refers to making the irradiation of X-ray beam certain point
The thickness of standard absorption piece required for dose rate reduction half, needs to measure or calculate for the half-value layer of X-ray production apparatus, with
Ensure the normal work of machine.The standard absorption piece of existing X-ray half-value layer is to pass through superposition using the aluminium flake of polylith independence
Mode is tested, and X-ray half-value layer test bracket is used for the aluminium flake for supporting and fixing different size thickness.Existing X-ray
Half-value layer test bracket uses corner support, and volume is not readily portable greatly；Height can not be conveniently adjusted；And for some
X-ray production apparatus, such as chest project X-ray, it is necessary to aluminium flake be placed vertically, and the aluminium flake on existing support is horizontal positioned,
Detection is can not meet to require.
Therefore, the prior art is defective, it is necessary to improve.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art there is provided a kind of X-ray half-value layer test bracket, can
Reduce volume, be conveniently adjusted height, aluminium flake horizontal positioned can be made.
The technical solution of the utility model is as follows：A kind of X-ray half-value layer test bracket, including：Tripod, installation are fixed
Supporting plate on the tripod, the aluminium flake being installed in the supporting plate and the catch located at the aluminium flake top surface, institute
State that supporting plate is L-shaped, including mutually angled the first face body and dihedron, first face body is away from the second face
The side of body end is provided with the middle of pit, the pit and is provided with first through hole, and the sheet aluminum base is embedded in the pit, described
Pit periphery is provided with some second through holes, and first face body is connected this one end with the dihedron provided with some threeways
Hole, the dihedron is provided with some third through-holes.
Further, the catch two ends are provided with fourth hole.
Further, the tripod includes three pin, and three pin are scalable and can be rotated above and below axle center.
Further, the supporting plate is made up with the catch of metal or plastics.
Further, the certain angle is 90 degree.
Using such scheme, the utility model supporting plate is L-shaped, when needing aluminium flake horizontal positioned, and supporting plate is led to
The third through-hole for crossing its first face body is lock onto on tripod, when needing vertically to place aluminium flake, supporting plate by its second
The third through-hole of face body is lock onto on tripod, it is thus possible to meet the detection of a variety of X-ray equipments, and tripod can be any
Stretch to adjust height.The utility model small volume and less weight, it is easy to store, it is easy to carry.
Brief description of the drawings
Structural representation when Fig. 1 is the utility model aluminium flake horizontal positioned.
Fig. 2 is structural representation when the utility model aluminium flake is placed vertically.
Fig. 3 is that the utility model aluminium flake places design sketch.
Fig. 4 is the structural representation of the utility model supporting plate.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Fig. 1 to Fig. 4 is please referred to, the utility model provides a kind of X-ray half-value layer test bracket, including：Tripod
10th, the supporting plate 20 that is fixed on the tripod 10, the aluminium flake 30 being installed in the supporting plate 20 and located at institute
State the catch 40 of the top surface of aluminium flake 30.The supporting plate 20 is L-shaped, including the first mutually angled face body 21 and second
Face body 22, in the present embodiment, the certain angle are preferably 90 °, first face body 21 away from the end of dihedron 22 one
Side is provided with the middle of pit 23, the pit 23 and is provided with first through hole 24, and the bottom of aluminium flake 30 is embedded in the pit 23, can
With according to the aluminium flake 30 that different-thickness is changed the need for detection.The two ends of catch 40 are provided with fourth hole 27, the catch 40
Aluminium flake 30 is fixed in the supporting plate 20 by bolt and nut.Some second through holes 25 are provided with the periphery of pit 23,
First face body 21 is connected this one end with the dihedron 22 and is provided with some third through-holes 26, the dihedron 22
Provided with some third through-holes 26, the supporting plate 20 is fixed on the tripod 10 by the third through-hole 26.Institute
Stating tripod 10 includes three pin, and three pin retractables simultaneously can rotate, thus can arbitrarily adjust three above and below axle center
The height of foot stool 10.The supporting plate 20 is made up with the catch 40 of high duty metal or plastics.
When detecting the half-value layer of X-ray, x-ray bombardment is set on half-value layer aluminium flake 30 through first through hole 24 in imaging
It is standby to be above imaged.
In summary, the utility model supporting plate is L-shaped, and when needing aluminium flake horizontal positioned, supporting plate passes through it
The third through-hole of first face body is lock onto on tripod, when needing vertically to place aluminium flake, and supporting plate passes through its dihedron
Third through-hole lock onto on tripod, it is thus possible to meet the detection of a variety of X-ray equipments, and tripod can arbitrarily stretch
To adjust height.The utility model small volume and less weight, it is easy to store, it is easy to carry.
Preferred embodiment of the present utility model is these are only, the utility model is not limited to, it is all in this practicality
Any modifications, equivalent substitutions and improvements made within new spirit and principle etc., should be included in guarantor of the present utility model
Within the scope of shield.
