Description

Technical Field

[0001] This utility model relates to the field of isotope separation and purification technology, specifically an adjustable support device. Background Technology

[0002] Isotopes are different nuclides of the same element that have the same number of protons but different numbers of neutrons. They are widely used in geology, environmental science, archaeology, and medicine. Isotope separation and purification refers to the technique of selectively extracting specific isotopes from a mixture based on differences in physicochemical properties. Common methods include chromatography, ion exchange, and membrane separation. Isotope separation columns, especially isotope ion exchange chromatography columns, are chemical separation tools that utilize the principle of selective separation and extraction of ions with different charges using ion exchange resins for isotope extraction. They consist of a column body, column cap, column bottom, and ion exchange resin.

[0003] In the chemical purification process, existing isotope separation columns need to be placed on a purification support device. The support tray on the device keeps the separation column in a vertical position to ensure the normal operation of the chemical separation process. However, due to requirements for separation efficiency, purity, recovery rate, and specific isotope separation, the heights of different isotope separation columns are inconsistent. Since existing purification support devices are generally one-piece, it is difficult to conveniently adjust the height of the support tray according to the column length of different isotope separation columns. To facilitate convenient adjustment of the support tray height according to the column length of different isotope separation columns, an adjustable support device is now provided, which can eliminate the drawbacks of existing devices.

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] In one embodiment, such as Figures 1-5 As shown, an adjustable support device includes a support rod 1, with a base 5 rotatably connected to the bottom end of the support rod 1. Two support trays 4 are symmetrically arranged on the outer wall of the support rod 1. A fixing ring 3 is provided on the inner side of each of the two support trays 4. A limit ring is integrally formed on the outer wall of the fixing ring 3. The support tray 4 is slidably sleeved on the outer wall of the limit ring, and the fixing ring 3 is slidably sleeved on the outer wall of the support rod 1. An adjustment mechanism for individually adjusting the height of the two support trays 4 is provided on the support rod 1.

[0034] The regulating mechanism includes:

[0035] A locking assembly is mounted on support rod 1;

[0036] The engaging assembly includes: a connecting pull block 201 disposed on the upper surface of the support rod 1, and a plurality of positioning blocks 202 are fixedly connected to the bottom end of the connecting pull block 201 at equal intervals in the circumferential direction. The bottom outer wall of the plurality of positioning blocks 202 is hemispherical, and the plurality of positioning blocks 202 penetrate into the interior of the support rod 1.

[0037] A rotating component is provided on the connecting block 201;

[0038] The fixed ring 3 is provided with a first positioning component;

[0039] In this embodiment, when in use, pulling the connecting block 201 causes the connecting block 201 to move synchronously until all the positioning blocks 202 are separated from the support rod 1, thereby releasing the locking of the connecting rotating rod 203. Then, the connecting block 201 is rotated, and at this time, the locking of the support tray 4 can be released by the adjustment mechanism.

[0040] Then, the two support trays 4 are pushed to move. During this process, the fixing ring 3 is driven by the support trays 4 and moves up and down along the outer wall of the support rod 1. During this process, the support trays 4 can be easily moved and positioned by the adjustment mechanism, which is beneficial to the convenient adjustment of the height of the support trays 4 according to the column length of different isotope separation columns.

[0041] After adjusting the height of the two support trays 4 respectively, the above operation is reversed by rotating the connecting block 201 in the opposite direction. This allows the two support trays 4 to be easily locked and fixed, which helps to prevent the support trays 4 from shifting during use.

[0042] In one embodiment, such as Figures 2-5 As shown, the rotating assembly includes:

[0043] A fixed baffle 205 is provided inside the connecting pull block 201. A connecting rotating rod 203 is fixedly connected to the bottom end of the fixed baffle 205. The connecting rotating rod 203 passes through the connecting pull block 201 to the inside of the support rod 1. The connecting pull block 201 is slidably connected to the connecting rotating rod 203 and the fixed baffle 205. The connecting rotating rod 203 is rotatably connected to the support rod 1.

[0044] A reset component is provided on the connecting rod 203;

[0045] The reset component is a spring 204 sleeved on the outer wall of the connecting rod 203. One end of the spring 204 contacts the outer wall of the fixed baffle 205, and the other end of the spring 204 contacts the inner wall of the connecting pull block 201. Through the cooperation of the rotating component and the reset component, the connecting pull block 201 can be pushed to insert the positioning block 202 into the interior of the support rod 1, which is beneficial to locking the connecting rod 203.

[0046] In one embodiment, such as Figures 2-5 As shown, the first positioning component includes: two limiting baffles 209 symmetrically arranged inside the fixed ring 3. Each of the two limiting baffles 209 has an elastic rubber pad 208 at the end away from the support rod 1. One end of the elastic rubber pad 208 contacts the inner wall of the fixed ring 3, and the other end of the elastic rubber pad 208 contacts the outer wall of the limiting baffle 209. A positioning rod 2010 is fixedly connected to the end of each of the two limiting baffles 209 away from the elastic rubber pad 208. The outer wall of the end of the positioning rod 2010 away from the limiting baffle 209 is hemispherical. The positioning rod 2010 passes through the fixed ring 3 to the interior of the support rod 1. The limiting baffles 209 and the positioning rod 2010 are slidably connected to the fixed ring 3.

[0047] A first limiting component is provided on the support rod 1;

[0048] A second positioning component is provided on the fixed ring 3;

[0049] The first limiting component includes: a second linear slide groove 2013 opened at the junction of the support rod 1 and the positioning rod 2010, the positioning rod 2010 and the second linear slide groove 2013 are slidably connected, and the support rod 1 is provided with a plurality of positioning slots 2012 vertically and equidistantly opened on the inner wall of the second linear slide groove 2013, the inner wall of the positioning slots 2012 and the outer wall of the positioning rod 2010 are matched with each other. Through the cooperation of the first positioning component and the first limiting component, the support tray 4 can be moved and positioned.

[0050] In one embodiment, such as Figures 2-5 As shown, the second positioning component includes: two positioning slide rods 207 symmetrically fixedly connected to the inner wall of the fixing ring 3. The outer walls of the two positioning slide rods 207 that are close to each other are hemispherical. Both positioning slide rods 207 penetrate through the support rod 1 to the interior of the connecting rotating rod 203. Both positioning slide rods 207 are slidably connected to the support rod 1. The two positioning slide rods 207 and the two limiting baffles 209 are interleaved.

[0051] A second limiting component is provided on the connecting rod 203;

[0052] The second limiting component includes: two first linear slide grooves 2011 symmetrically opened on the outer wall of the connecting rod 203; multiple arc-shaped slide grooves 206 vertically and equidistantly opened on the outer side of the two first linear slide grooves 2011 on the connecting rod 203; the inner cavity of the multiple arc-shaped slide grooves 206 communicates with the inner cavity of the first linear slide grooves 2011; the positioning slide rod 207 is slidably connected to the inner wall of the arc-shaped slide grooves 206 and the first linear slide grooves 2011; the multiple arc-shaped slide grooves 206 are respectively at the same height as the multiple positioning slots 2012; through the cooperation of the second positioning component and the second limiting component, the support tray 4 can be locked to prevent the support tray 4 from shifting during use.

[0053] The above embodiments disclose an adjustable support device. It should be noted that the support rod 1, the fixing ring 3, the support tray 4, the chassis 5, and some components involved in the adjustment mechanism are all made of acid-resistant materials, such as plexiglass or special plastics.

[0054] When in use, pull the connecting block 201 to rise along the outer wall of the connecting rod 203 and the fixed baffle 205. At this time, the connecting block 201 retracts by moving the compression spring 204. At the same time, multiple positioning blocks 202 move synchronously under the drive of the connecting block 201 until multiple positioning blocks 202 are separated from the support rod 1, thereby releasing the locking of the connecting rod 203.

[0055] Then, rotating the connecting pull block 201 drives the fixed baffle 205 to rotate. At this time, the connecting rod 203, driven by the fixed baffle 205, drives the arc-shaped slide groove 206 to slide along the outer wall of the positioning slide rod 207 until the outer wall of the positioning slide rod 207 contacts the inner wall of the first straight slide groove 2011, thereby releasing the locking of the support tray 4.

[0056] Then, the two support trays 4 are moved separately. During this process, the fixing ring 3 moves up and down along the outer wall of the support rod 1 under the action of the support tray 4. At this time, the positioning rod 2010, through the obstruction of the inner wall of the positioning slot 2012 by the hemispherical outer wall, pushes the limiting baffle 209 to slide along the inner wall of the support tray 4. At the same time, the limiting baffle 209 contracts by moving and squeezing the elastic pad 208 until the positioning rod 2010 contacts the inner wall of the second linear slide groove 2013, so that the positioning rod 2010 can slide along the inner wall of the second linear slide groove 2013. The positioning slide rod 207 slides synchronously along the inner wall of the first straight slide groove 2011 under the drive of the fixing ring 3. When the positioning rod 2010 moves to the port of the next positioning slot 2012 under the drive of the fixing ring 3 and the support tray 4, the elastic pad 208 pushes the limit baffle 209 to reset by rebound, so that the positioning rod 2010 can be inserted into the inner cavity of the next positioning slot 2012. This allows the support tray 4 to be moved and positioned conveniently, which is beneficial to the convenient adjustment of the height of the support tray 4 according to the column length of different isotope separation columns.

[0057] After adjusting the height of the two support trays 4, the above operation is reversed by rotating the connecting block 201 in the opposite direction. This allows the two support trays 4 to be easily locked and fixed, which helps to prevent the support trays 4 from shifting during use. When the support trays 4 need to be rotated, the support trays 4 are manually pulled along the outer wall of the limiting ring to rotate, so that the support trays 4 can rotate outside the fixing ring 3.

[0058] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
