Description
Technical Field
The utility model relates to an ionization chamber protecting cover used when the periphery of the ionization chamber is overhauled.
Background
When the ionization chamber is disassembled and maintained, the accident that the thin film of the ionization chamber is accidentally punctured by a heavy object to cause the abandonment of the ionization chamber is easy to occur.
The reason for this is that, in the beam axis, when the optical box is removed, the ionization chamber is exposed to the outside, and the film of the open ionization chamber is only 0.016mm thick, and after long-term X-ray irradiation, the film becomes brittle and is more likely to be broken. At this time, if an object falls on the ionization chamber film in the center of the ionization chamber, the object can be broken down to form damage.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing an ionization chamber protecting cover can shield the ionization chamber completely and fix a position, falls into the heavy object in avoiding the ionization chamber and damages.
In order to achieve the above object, the utility model adopts the following technical scheme:
a protective cover for an ionization chamber, comprising: the ionization chamber comprises a circular hard sheet body, wherein the diameter of the hard sheet body is larger than the outer diameter of the ionization chamber;
one end of the hard sheet body is provided with an arc-shaped baffle plate extending downwards, and the inner edge of the arc-shaped baffle plate can be abutted against the outer edge of the proximal end part of the ionization chamber to form positioning;
and the left side and the right side of the hard sheet body, which correspond to the distal part of the ionization chamber, are respectively provided with a pin hole, a pin can be inserted into the pin holes to expose the conical head end, and the exposed conical head end of the pin can be tightly abutted against the outer edge of the distal part of the ionization chamber.
The ionization chamber protective cover, wherein: the diameter of the hard sheet body is 10-30mm larger than the outer diameter of the ionization chamber.
The ionization chamber protective cover, wherein: a detachable handle is also fixed on the arc-shaped baffle.
The ionization chamber protective cover, wherein: the detachable handle is a bolt.
The ionization chamber protective cover, wherein: still have a hand-held type frock, it includes the grab handle and the horizontal bar of being connected with the grab handle, the both ends of horizontal bar respectively with one the tail end fixed connection of pin.
Compared with the prior art, adopt above-mentioned technical scheme the utility model has the advantages of: can be conveniently installed on the ionization chamber and form stable combination, thereby improving the safety of the maintenance work around the ionization chamber.

Description of reference numerals: an ionization chamber 1; a wire plug 11; a hard sheet body 2; an arc baffle 3; a handle 4; a pin 5; a grip 6; and a cross bar 7.
Detailed Description
Referring to fig. 1, 2, 3 and 4, one end of a wire plug 11 close to an ionization chamber 1 is a far end, and the other end is a near end, the utility model provides a protective cover of the ionization chamber, the main body of which is a circular hard sheet body 2, the diameter of which is 10-30mm larger than the outer diameter of the ionization chamber 1;
one end of the hard sheet body 2 is provided with an arc baffle 3 extending downwards, and the shape of the inner edge of the arc baffle 3 is matched with the shape of the outer edge of the proximal part of the ionization chamber 1, so that the arc baffle and the outer edge can be abutted to each other to form positioning;
a detachable handle 4 is further fixed on the arc-shaped baffle 3, preferably made of bolts, and the hard sheet body 2 can pass through the lower part of the cross iron at the near end of the ionization chamber 1 by holding the handle 4 by hand until the arc-shaped baffle 3 is abutted and positioned with the near end part of the ionization chamber 1;
the hard sheet body 2 is provided with a pin hole corresponding to the left side and the right side of the distal part of the ionization chamber 1 respectively, the pin 5 can be inserted into the pin hole to expose the conical head end, and the conical head end exposed by the pin 5 is tightly abutted with the outer edge of the distal part of the ionization chamber 1, so that the hard sheet body 2 cannot retreat to be separated from the ionization chamber 1;
in order to facilitate the insertion of the pins 5, the utility model also provides a handheld tool, which comprises a grab handle 6 and a horizontal bar 7 connected with the grab handle 6, wherein the two ends of the horizontal bar 7 are respectively fixedly connected with the tail end of one pin 5, when in use, the grab handle 6 is held by hand, the horizontal bar 7 is communicated with the two pins 5 to stretch into the gap between the part in the treatment head and the ionization chamber 1, and then the head ends of the two pins 5 are inserted into the two pin holes, so that the hard sheet body 2 can not retreat and is separated from the ionization chamber 1; at this time, the handle 4 on the arc-shaped baffle plate 3 can be disassembled so as to be beneficial to subsequent maintenance work.
After the maintenance is accomplished, install handle 4 for cowl 3 again, mention hand-held type frock can be taken out stereoplasm lamellar body 2 from ionization chamber 1 and come out, and concrete process is no longer repeated.
The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
