Description

Technical Field

[0001] This utility model belongs to the field of BNCT technology, specifically relating to a combined target clamp for BNCT. Background Technology

[0002] BNCT is a targeted, cell-level precision radiotherapy that combines radiation and drugs. The accelerator boron neutron capture therapy experimental device is a setup used to realize BNCT treatment. The accelerator boron neutron capture therapy experimental device includes a target. In the BNCT device, the component that generates neutrons is called the target. The target is bombarded by a high-energy proton beam and generates high-energy neutrons. Currently, the target is fixed to the target structure with bolts.

[0003] The patent CN221181421U discloses a target replacement system for BNCT. This patent uses a rotating snap-fit ​​method to install the target clamp and the target structure, and uses a rotating release method to separate the two, which achieves convenient disassembly and assembly. However, this method requires precise positioning. Once the positioning is deviated, it is easy to cause the phenomenon of misalignment during installation. Therefore, there is still room for improvement in practical applications. Utility Model Content

[0004] The purpose of this invention is to provide a combined target fixture for BNCT, in order to solve the problem mentioned in the background art that the existing target fixtures have excessively high precision requirements during installation and are prone to misalignment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined target clamp for BNCT, comprising a base with concentric annular grooves and a limiting area inside; a clamping assembly consisting of a clamping member and an adjusting member, wherein one end of the clamping member is located in the annular groove and the other end extends into the limiting area, while the adjusting member is placed in the annular groove and abuts against the clamping member. By moving the clamping member toward the interior of the limiting area, the target structure placed in the limiting area is clamped and limited; it also includes a cover ring, which is installed on the top of the base and completely covers the area of ​​the annular groove, used to limit the adjusting member and prevent the adjusting member from falling out of the annular groove.

[0006] Preferably, a guide hole is provided at an equal angle between the annular groove and the limiting area, and the abutting member is a abutting rod that passes through the guide hole, thereby abutting the target structure placed in the limiting area.

[0007] Preferably, the end of the abutment extending into the limiting area is provided with a guide portion in an inclined manner from top to bottom. When the target structure is inserted, the guide portion can be used to guide it and avoid a tight fit.

[0008] Preferably, the adjusting component is an airbag, which abuts against one end of the abutment rod. When the target structure is inserted into the limiting area, the target structure will push the abutment rod toward the airbag. At this time, the airbag rebounds and presses the abutment rod against the target structure, thereby achieving installation.

[0009] Preferably, a through hole is provided at the surface edge of the cover ring, and a screw hole corresponding to the position of the through hole is provided at the top of the base. A bolt is screwed into the through hole (not shown in the figure). The bolt is screwed into the screw hole to realize the installation of the base and the cover ring.

[0010] Preferably, the top of the cover ring is also provided with a guide groove, the projection of which coincides with the curved inner wall of the limiting area.

[0011] Preferably, the guide groove and the abutment are staggered, and the guide groove allows an external robot arm to be quickly inserted from the gap between the two guide parts. The depth of the guide groove is half the thickness of the cover ring.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention allows for the clamping of target structures of different sizes, with low requirements for installation and removal precision, ensuring a high success rate in actual use. Furthermore, it boasts high versatility, enabling stable installation of target structures of various specifications, thus enhancing flexibility and practicality. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1 to 3 This utility model provides a technical solution: a combined target clamp for BNCT, comprising...

[0022] The base 100 has concentric annular grooves 104 and limiting areas 107 inside;

[0023] The clamping assembly consists of a clamping member and an adjusting member. One end of the clamping member is located in the annular groove 104, and the other end extends into the limiting area 107. The adjusting member is placed in the annular groove 104 and abuts against the clamping member. By moving the clamping member toward the interior of the limiting area 107, the target structure placed in the limiting area 107 is clamped and limited.

[0024] It also includes a cover ring 200, which is mounted on top of the base 100 and completely covers the area of ​​the annular groove 104 to limit the adjustment member and prevent the adjustment member from falling out of the annular groove 104.

[0025] In this embodiment, preferably, a guide hole 106 is provided at an equal angle between the annular groove 104 and the limiting area 107, and the abutting member is a abutting rod 101 that passes through the guide hole 106, so that the target structure placed in the limiting area 107 is abutted by the abutting rod 101.

[0026] In this embodiment, preferably, the end of the abutment 101 extending to the limiting area 107 is provided with a guide portion 102 in an inclined manner from top to bottom. When the target structure is placed, the guide portion 102 can be used to guide it and avoid a tight fit.

[0027] In this embodiment, preferably, the adjusting component is an airbag 103, which abuts against one end of the abutment rod 101. When the target structure is inserted into the limiting area 107, the target structure will push the abutment rod 101 toward the airbag 103. At this time, the airbag 103 will rebound to press the abutment rod 101 against the target structure, thereby realizing the installation.
