Abstract
The utility model discloses a collimator, which comprises a shell (1) and diaphragms (2), wherein the diaphragms (2) are movably arranged inside the shell (1), and a cushion block (3) for fixing the diaphragms (2) is respectively arranged between every two adjacent diaphragms (2). The collimator has advantages of ingenious structural design and convenience in manufacturing and installation, and due to the adoption of the collimator, not only can a scattering field and a radiation field be conveniently adjusted, but also the radiation leakage can be effectively reduced, the environment can be protected, and the security of the human body can be ensured.
Description
Technical field
The utility model relates to a kind of radiation appliance, particularly a kind of collimating apparatus.
Background technology
At present; Existing collimating apparatus mainly comprises shell and the diaphragm that is provided with in the enclosure; Wherein shell is a straight barrel type shell, and said shell and diaphragm adopt and be fixedly connected, and there is following deficiency in such structure: 1. owing to diaphragm and shell for being fixedly connected; Cause diaphragm not change, can't regulate scattering and radiation field size.2. because shell is a straight-tube shape, in use, cause the outside leakage of radioactive source bigger, environment is polluted, human body is worked the mischief.
The utility model content
The purpose of the utility model just provides a kind of collimating apparatus of replaceable diaphragm.
The purpose of the utility model is to realize through such technical scheme. a kind of collimating apparatus, comprise shell and diaphragm, said diaphragm is provided with in the enclosure versatilely, the said cushion block that between adjacent two diaphragms, is provided with fixed aperture.
In order to reduce the leakage of radiation; Said shell adopts the secondary maze setting; Wherein, Secondary maze is to be provided with like this: said shell is divided into inducer, interlude and outlet section, and the diameter of said outlet section is greater than inducer, and the two ends of said interlude are connected with outlet section with inducer through step respectively.
Owing to adopted technique scheme, the utlity model has structural design ingenious, make convenient installation, adopt it not only can regulate scattering and radiation field size easily; Simultaneously; Also effectively reduce the leakage of radiation, protected environment, guaranteed human body safety.
Description of drawings
The description of drawings of the utility model is following:
Fig. 1 is the structural representation of the utility model.
Embodiment
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation; But the utility model is not limited to these embodiments; Any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of collimating apparatus comprises shell 1 and diaphragm 2, and said diaphragm 2 is arranged in the shell 1 versatilely, the said cushion block 3 that between adjacent two diaphragms 2, is provided with fixed aperture 2.
The scattering of coming out when needs adjustment radioactive source is during with radiation field size, only need shell 1 interior diaphragm 2 be changed to get final product.
Further; Said shell 1 adopts the secondary maze setting; This secondary maze is that shell 1 is divided into inducer 4, interlude 5 and outlet section 6 with setting, and the diameter of said outlet section 6 is greater than inducer 4, and the two ends of said interlude 5 are connected with outlet section 6 with inducer 4 through step 7 respectively.
Scattered-out beam dispels the heat through diaphragm, owing to receive the influence at step 7 places, has so just reduced leakage.
Claims (3)
1. a collimating apparatus comprises shell (1) and diaphragm (2), it is characterized in that: said diaphragm (2) is arranged in the shell (1) versatilely, the said cushion block (3) that between adjacent two diaphragms (2), is provided with fixed aperture (2).
2. collimating apparatus as claimed in claim 1 is characterized in that: said shell (1) adopts the secondary maze setting.
3. collimating apparatus as claimed in claim 2; It is characterized in that: said shell (1) is divided into inducer (4), interlude (5) and outlet section (6); The diameter of said outlet section (6) is greater than inducer (4), and the two ends of said interlude (5) are connected with outlet section (6) with inducer (4) through step (7) respectively.
