In order for those skilled in the art to better understand the technical solutions of the invention, the invention will be described in detail below with reference to the drawings. The description of this part is only empirical and interpretible, and the scope of protection of the present invention is not limited in any way.

As shown in FIGS. 1 and 3, the specific structure of the present invention is as follows. It is a sample environment equipment that can easily convert the product to be measured, and it is equipped with a base 55 and an elevating movable device 51, and an elevating cylinder 52 is arranged under the elevating movable device 51 and under the elevating cylinder 52. , The elevating bracket 53 is connected, and the upper mechanism is connected to the elevating bracket 53. The upper mechanism includes an upper plate 3 and a downward pressing device 7, and the upper plate 3 is locked with the elevating bracket 53 via a bolt. An elevating and connecting block 54 is arranged so as to be connected, a conversion motor 56 is embedded in the base 55, a conversion rotation sleeve 57 is mounted on the output shaft of the conversion motor 56, and the conversion rotation sleeve 57 is annular. Four conversion connecting rods 58 are evenly arranged along the above, and the conversion table 59 is connected to the conversion connecting rod 58 having a phase difference of 180 ° C., and the lower mechanism is attached to the conversion table 59. 60 is arranged, the lower mechanism includes a lower plate 1 and a material supply holding device attached to the lower plate 1, and a cylinder 2 is arranged between the lower mechanism 60 and the upper mechanism located in the test section. The lower plate 1, the cylinder 2 and the upper plate 3 form a removable sample tube, and the lower plate 1 and the upper plate 3 have an annular insertion block 4 that can be inserted into the wall of the cylinder 2. Arranged so as to be fixed, a through hole 5 is provided on the side surface of the cylinder 2, and a removable screw 10 is linked and removable via a screw thread on the upper outer side of the cylinder 2. The end of 10 is a smooth rod and can be inserted into the annular insertion block 4 located below the top plate 3.

When specifically used, the product 9 to be measured is first attached to the material supply holding device 6 of one of the lower mechanisms 60, and then the conversion rotary sleeve 57 is rotated by 180 ° C. by the conversion motor 56 to be measured. After the lower mechanism 60 to which the product 9 is attached is positioned below the cylinder 2, the elevating bracket 53 is lowered by the elevating cylinder 52, and the entire connecting portion composed of the upper mechanism and the cylinder 2 is further lowered. , The annular insertion block 4 in the cylinder 2 and the lower plate 1 are linked, and further complete the assembly of the entire sample tube. Subsequently, a vacuum environment and a constant temperature environment are constructed in the sample tube by the parts arranged on the cylinder 2 and the upper plate 3, and then high-speed protons are released using a proton emitter, and the high-speed protons are released from the through-hole 5 ( The penetration port is usually set to a material that is easily penetrated by protons. For example, when using an aluminum plate, it does not affect the vacuum environment.) Enter the sample tube and shoot the product 9 to be measured to increase the beam intensity. The impact of the neutron target is completed by generating a high, pulsed, short proton beam that diverges into a spectroscope located within the sample tube. At the same time as conducting the neutron scattering experiment, the following product 9 to be measured is attached to the material supply sandwiching device 6 of the other lower mechanism 60, and after the neutron scattering experiment is completed, the elevating bracket 53 is raised by the elevating cylinder. Furthermore, after the entire upper mechanism and the cylinder 2 are separated from the lower mechanism 60, another lower mechanism 60 is transferred to the lower side of the cylinder 2 by a conversion motor, and after the assembly of the sample tube is completed, a specific environment is created. Because the air was taken into the vacuum environment and the heat dissipated from the constant temperature environment was small, the time required to reconstruct the environment was reduced.

As shown in FIG. 2, a conversion position limiting block 61 linked to the base 55 so as to be in contact with four conversion tables 59 along the rotation direction is arranged, and at the outer ends of the two conversion connecting rods 58. , A conversion distance measuring instrument 62 facing the axial direction is arranged.

As shown in FIGS. 3 and 5, the material pressing device 7 includes a downward pressing bracket 21 arranged on an upper plate, and an electric telescopic rod 22 facing in the vertical direction is arranged on the downward pressing bracket 21. A downward pressing rod 23 is connected to the electric telescopic rod 22 so as to penetrate the upper plate 3 and seal with the upper plate 3, and a downward pressing block 25 is connected to the lower side of the downward pressing rod 23. A downward pressing tightening gas sac 27 is arranged below the downward pressing block 25, the downward pressing tightening gas sac 27 is connected to a pneumatic device, a vacuum pump 8 is arranged on the upper plate 3, and the vacuum pump 8 is arranged. The vacuum pump 8 communicates with the cavity of the sample tube.

The electric telescopic rod 22 lowers the downward pressing rod 23, further lowers the downward pressing block 25 to contact the upper end of the product 9, and then the pneumatic device injects air into the downward pressing tightening gas sac 27. Further, the upper part of the product 9 is tightened to limit the position, and the situation where the product 9 comes off while the downward pressing block 25 is pressing downward is avoided. Subsequently, the amount of expansion and contraction of the electric expansion rod 22 is controlled, that is, the product 9 is achieved to the required compressive stress, and in this process, the vacuum pump 8 is driven to put the sample tube in a vacuum state, and the downward pressing rod is used. Since the diameter does not need to be larger than the entire downward pressing block, the size of the entire downward pressing rod is reduced to facilitate sealing, and there is no need to extract the product from the sample rod so that it does not interfere with other parts. The method of removing the entire upper plate is adopted, and it can be better combined with the elevating movable device. If the tensile stress is designed, it is only necessary to set the lower side of the downward pressing block to the holding portion.

As shown in FIGS. 5 and 6, the electric telescopic rod 22 is connected to the downward pressing rod 23 via a coupling 28 made of a hard plastic material, and the downward pressing electromagnet 26 is embedded in the downward pressing block 25. The material of the downward pressing block is hard plastic, and a downward pressing sleeve 24 linked to the downward pressing electromagnet 26 is arranged at the lower end of the downward pressing rod 23, and the downward pressing sleeve 24 is , Magnetically links with the downward pressing electromagnet 26.

By separating it from the pressing block, the whole can be easily removed, and by removing the coupling 28, the electric telescopic rod can be separated from the downward pressing rod 23, and the whole can be easily disassembled and maintained. ..

As shown in FIG. 6, a screw thread is arranged on the outside of the coupling 28, and a downward pressing tightening cylinder 29 arranged horizontally and facing the cylinder head is 2 on the downward pressing bracket 21. A downward pressing tightening arc-shaped block 30 is connected to the push rod of the downward pressing tightening cylinder 29, and an internal screw is arranged inside the downward pressing tightening arc-shaped block 30, and the internal screw is coupled. Coordinates with threads located on the outside of 28.

After the electric telescopic rod reaches the required amount of expansion and contraction, it needs to be locked. The existing operation sets the electric telescopic rod to an auto-lock structure, but the structure is extremely complicated. On the other hand, in the present invention, a screw thread is arranged on the outside of the coupling 28, the downward pressing and tightening arcuate block 30 is moved by the downward pressing and tightening cylinder 29, and the internal screw of the downward pressing and tightening arcuate block 30 is further moved. The electric telescopic rod can be locked by linking the screw thread arranged on the outside of the coupling 28. Compared to the auto-lock structure of the electric telescopic rod, the structure is simple, and even if the electric telescopic rod 22 and the downward pressing rod 23 are removed, the coupling 28 can also be tightened. The electric telescopic rod 22 and the coupling 28 can be removed simply by retracting the electric telescopic rod. It is also possible to prevent the lower portion of the coupling 28 from falling.

As shown in FIGS. 5 and 7, a lead wire passing tube 31 penetrating the upper plate 3 is arranged, and a lead wire passing sealing sleeve 32 is sealed under the lead wire passing tube 31. The air pipe 33 and the wire pipe 34, which are rigid materials, are connected to the sealed sleeve 32 for passing the wire, which is covered, and the other end of the air pipe 33 and the wire pipe 34 is pressed downward. Fixed to the block 25, the lead wire of the downward pressing electromagnet 26 penetrates the lead wire tube 34 and passes through the lead wire passing tube 31, and the air supply tube of the downward pressing tightening gas bag 27 communicates with the air tube 33, and The air pipe 33 communicates with the ventilation hose 35 penetrating the lead wire passage pipe 31, and the ventilation hose 35 communicates with the air pump 37 of the gas sac arranged in the downward pressing bracket 21.

Since the air supply tube of the downward pressing tightening gas bag 27 and the conducting wire of the downward pressing electromagnet 26 always pass through the upper plate, if the design is not good, there is a high possibility of damaging the vacuum environment. In the present invention, the conductor passage pipe 31 is designed and combined with the conductor passage sealing sleeve 32 to realize sealing, and the conductor passage sealing sleeve 32 is provided via the air pipe 33 and the conductor pipe 34, which are rigid materials. By connecting with the downward pressing block 24, the conducting wire passing sealing sleeve 32 is linked with the conducting wire passing pipe 31 so as to be sealed and covered, and serves as a guide to some extent when the downward pressing block 24 descends. At the same time, it maintains an excellent vacuum environment and does not cause interference in the removal process.

As shown in FIG. 4, the material supply pinching device 6 includes a pinching elevating bracket 11 arranged under the lower plate 1, and a pinching elevating ball screw 12 is screw-linked to the pinching elevating bracket 11. The pinching elevating ball screw 12 is associated with the pinching elevating nut 13, and the upper end of the pinching elevating ball screw 12 penetrates the lower plate 1 and is connected to the pinching elevating table 14, and the pinching portion is attached to the pinching elevating table 14. The elevating and sealing sleeve 15 is arranged and is arranged under the holding elevating table 14, and the elevating and sealing sleeve 15 can move relative to the lower plate 1 and is linked so as to be sealed. 12 It is in the elevating sealing sleeve 15.

Due to the structure of the material supply pinching device 6, the pinching elevating table 14 can be lifted and lowered by the rotation of the pinching lifting ball screw 12, and the pinching portion and the parts sandwiched therein can also be lifted and lowered for easy adjustment. .. Further, by arranging the elevating and sealing sleeve 15, while maintaining the sealing performance of the lower plate 1 during elevating and lowering, it does not affect the elevating and lowering of the holding elevating table 14, and conversely serves as a guide.

As shown in FIG. 4, the pinching portion includes a pinching mounting block 16 arranged on a pinching elevating table 14, the pinching mounting block 16 is arranged in the vertical direction, and at least three or more are arranged, and the sandwiching portion is arranged. A holding screw 17 facing in the horizontal direction is arranged on the mounting block 16, the holding lock nut 19 is linked to the holding screw 17, and the holding screw 17 is connected to the holding block 18 linked to the product.

The specific operation of the pinching portion is as follows. First, the product 9 is placed in the center of the pinching mounting block 16, then the pinching block 18 can be moved by the pinching screw 17, the product 9 is further pinched by the pinching block 18, and then the pinching screw 17 is used by the pinching lock nut 19.
