Description

Technical Field

[0001] This utility model relates to the field of detection support technology, and in particular to a sample cell fixing support for analytical instruments. Background Technology

[0002] The sample cell holder is a key component of analytical instruments. Its function is to stably fix the sample cell in a specific position within the instrument, ensuring its stability during analysis and enabling the instrument to accurately acquire various parameters of the sample. Whether it is spectral analysis, chromatographic analysis, or other types of analytical instruments, the performance of the sample cell holder directly affects the accuracy and reliability of the analytical results. It must not only ensure the stability of the sample cell but also facilitate its installation, disassembly, and adjustment to meet different experimental needs and diverse sample cell specifications.

[0003] Early analytical instrument sample cell holders consisted of a simple metal frame and clamps, secured with screws. However, clamping different sample cells was cumbersome, requiring repeated screw adjustments to the clamp's position and tightness. To address these issues, existing holders employ adjustable clamping structures, using spring clips and sliding guides for rapid sample cell positioning and clamping. However, these holders still suffer from inconvenience. While the adjustable clamps allow for quick clamping of the sample cell through spring deformation, avoiding the tedious screw-based method, the limited compatibility of the spring clips with the sample cell means that manual adjustment of the clip's position and angle is still necessary for sample cells of different shapes and sizes. This results in numerous steps and time-consuming operation when clamping different sample cells, failing to meet the demands of efficient experiments. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a sample cell fixing bracket for analytical instruments, which aims to improve the problem that in the prior art, when dealing with sample cells of different shapes and sizes, it is still necessary to manually adjust the position and angle of the buckle.

The inner wall of the sliding block is rotatably connected to a clamping block. The outer wall of the sliding block is provided with a limit component.

[0008] The telescopic mechanism includes multiple rotating bars, the outer walls of which are rotatably connected to the inner wall of the base plate. An L-shaped block is slidably connected to each adjacent side of the rotating bars. A support plate is rotatably connected to the bottom end of each L-shaped block. A rotating plate is rotatably connected to the outer wall of each rotating bar. A connecting block is rotatably connected to each adjacent side of each rotating plate. A fixing bolt is threaded onto the inner wall of each rotating bar. A suction cup is fixedly connected to the bottom end of the support plate. A sliding assembly is provided at the center of the bottom end of the base plate.

[0009] As a further description of the above technical solution:

[0010] The fixed support assembly includes a U-shaped block, the inner wall of which is located at the bottom of the outer wall of the column. An arc-shaped block is fixedly connected to the front side of the inner wall of the U-shaped block, and a fastening bolt is provided on the rear side of the U-shaped block. The outer wall of the fastening bolt is threadedly connected to the rear side of the U-shaped block, and a movable clamping block is rotatably connected to the front end of the fastening bolt. A limit ring is fixedly connected to the front end of the U-shaped block.

[0011] As a further description of the above technical solution:

[0012] The adjustment assembly includes a sliding hollow block, the inner wall of which engages with the top of the outer wall of the column. Adjusting nuts are threaded onto both the left and right sides of the sliding hollow block. A sliding rod is slidably connected to the left side of the inner wall of the sliding hollow block. A lower clamping block is fixedly connected to the front end of the sliding rod. An upper clamping block is rotatably connected to the top of the outer wall of the lower clamping block. Return springs are fixedly connected to the rear sides of the inner walls of both the lower clamping block and the upper clamping block.

[0013] As a further description of the above technical solution:

[0014] The sliding assembly includes multiple limiting rods, the outer walls of which are respectively fixedly connected to the outer wall of the rotating bar. The inner wall of the L-shaped block is provided with a slide rail, and a slide groove is fixedly connected to the bottom center of the seat plate. The outer wall of the slide groove is slidably connected to the inner wall of the connecting block.

[0015] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by placing the sample cell above the grooved platform, rotating the rotating block drives the hollow bevel gear ring to rotate synchronously. Under the meshing relationship between the hollow bevel gear ring and multiple bevel gears, the threaded rod rotates accordingly, causing the sliding block connected by the outer thread to slide in the limiting groove on the inner wall of the grooved platform. The cooperation between the limiting strip and the limiting groove restricts the movement direction of the sliding block, ensuring that it moves in a straight line. The movement of the sliding block will drive the clamping block to move, thereby realizing the clamping of sample cells of different sizes, and thus quickly completing the clamping and fixing of the sample cell.

[0023] 2. In this utility model, the rotating plate is moved to a horizontal position by operating the rotating bar, and then the fixing bolt is rotated to release the connection between the rotating bar and the L-shaped block. The L-shaped block is pulled out to a suitable length as needed, and the fixing bolt is rotated again to lock the position. The suction cup ensures that the support plate is firmly attached to the plane. The cooperation between the slide rail and the slide groove makes the sliding smooth. The limit rod controls the moving direction of the connecting block, thereby adjusting the height of the bracket. Attached Figure Description

[0032] 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.

[0033] Reference Figure 1 , Figure 5 and Figure 6This utility model provides an embodiment of an analytical instrument sample cell fixing bracket, including a base plate 1, which is an important connecting structure of the entire bracket. A grooved platform plate 4 is fixedly connected to the top of the base plate 1, serving as the operating platform of the entire bracket. A rotating block 5 is rotatably connected to the bottom of the outer wall of the grooved platform plate 4, which is an important operating structure for connection adjustment.

An adjustment component 8 is installed at the top of the outer wall of the column 6 to adjust the position between instruments. A telescopic mechanism 3 is rotatably connected to the inner wall of the base plate 1. The linkage clamping mechanism 2 includes a hollow bevel gear ring 201, the bottom end of which is fixedly connected to the top of the rotating block 5. When the rotating block 5 rotates, it drives the hollow bevel gear ring 201 to rotate as well. Multiple threaded rods 202 are rotatably connected to the inner wall of the grooved platform plate 4. The threaded rods 202 provide a basis for the movement of the sliding block 204. A bevel gear 203 is fixedly connected to an adjacent end of each threaded rod 202. The outer walls of the multiple bevel gears 203 mesh with the outer wall of the hollow bevel gear ring 201. When the hollow bevel gear ring 201 rotates... This will drive the bevel gear 203 to rotate, which in turn drives the threaded rod 202 to rotate. A sliding block 204 is threadedly connected to the outer wall of the threaded rod 202. The sliding block 204 is an important component of the clamping mechanism. A clamping block 205 is rotatably connected to the inner wall of the sliding block 204. The clamping block 205 can better adapt to and clamp the sample cell. A limit component 206 is provided on the outer wall of the sliding block 204. The limit component 206 includes multiple limit strips 2061, the outer walls of which are respectively fixedly connected to the outer walls of the corresponding sliding blocks 204. A limit groove 2062 is formed on the inner wall of the grooved platform disk 4. The outer walls of the limit strips 2061 are slidably connected to the inner walls of the limit grooves 2062. Meanwhile, in the limit component 206... The action of 6 makes the sliding block 204 more convenient to move; the fixed bracket assembly 7 includes a U-shaped block 701, the inner wall of the U-shaped block 701 is set at the bottom of the outer wall of the column 6, the front side of the inner wall of the U-shaped block 701 is fixedly connected to an arc-shaped block 702, the rear side of the U-shaped block 701 is provided with a fastening bolt 703, the outer wall of the fastening bolt 703 is threadedly connected to the rear side of the U-shaped block 701, the front end of the fastening bolt 703 is rotatably connected to a movable clamping block 704, the front end of the U-shaped block 701 is fixedly connected to a limiting ring 705, tightening the fastening bolt 703 makes the movable clamping block 704 move closer to the arc-shaped block 702, clamping the column 6 in the middle of the U-shaped block 701, thereby fixing the limiting ring 705 at the required height;The adjusting component 8 includes a sliding hollow block 801. The inner wall of the sliding hollow block 801 engages with the top of the outer wall of the column 6. Adjusting nuts 802 are threaded onto both the left and right sides of the sliding hollow block 801. A sliding rod 803 is slidably connected to the left side of the inner wall of the sliding hollow block 801. After sliding the sliding hollow block 801 above the column 6 to the desired position, the adjusting nuts 802 are rotated to fix the moved position. Then, the sliding rod 803 is adjusted as needed within the sliding hollow block 801. 1. Slide out to the desired length, and then rotate the corresponding adjusting nut 802 to fix it. The front end of the sliding rod 803 is fixedly connected to the lower clamping block 804. The top of the outer wall of the lower clamping block 804 is rotatably connected to the upper clamping block 805. The rear side of the inner wall of both the lower clamping block 804 and the upper clamping block 805 is fixedly connected to the return spring 806. Place the required testing instrument between the lower clamping block 804 and the upper clamping block 805, and clamp and fix it under the action of the return spring 806.

[0034] Specifically, the sample cell is placed above the grooved platform disk 4. By rotating the rotating block 5, the hollow bevel gear ring 201 is driven to rotate synchronously. Under the meshing relationship between the hollow bevel gear ring 201 and multiple bevel gears 203, the threaded rod 202 is driven to rotate, causing the sliding block 204 with the outer threaded connection to slide in the limiting groove 2062 on the inner wall of the grooved platform disk 4. The limiting strip 2061 cooperates with the limiting groove 2062, thereby restricting the movement of the sliding block 204 and ensuring that it moves in a straight line. The movement of the sliding block 204 will drive the clamping block 205 to move, realizing the initial clamping of the sample cell. At the same time, the column 6 is rotated to fix the column 6 above the grooved platform disk 4. Then, the fixing bracket assembly 7 is fixed by tightening the fastening bolts 70. 3. Move the movable clamping block 704 closer to the arc-shaped block 702, clamp the column 6 in the middle of the U-shaped block 701, and then fix the limiting ring 705 at the required height to provide space for the testing instrument. Then, using the adjusting component 8, slide the sliding hollow block 801 above the column 6 to the required position, and then rotate the adjusting nut 802 to fix the moved position. Then, as needed, slide the sliding rod 803 out of the sliding hollow block 801, and after sliding out the required length, rotate the corresponding adjusting nut 802 to fix it. Place the testing instrument to be used between the lower clamping block 804 and the upper clamping block 805, and clamp and fix it under the action of the return spring 806, thereby quickly completing the clamping and fixing of the sample cell.

[0035] Reference Figure 1 , Figure 2 and Figure 4The telescopic mechanism 3 includes multiple rotating bars 301. The outer walls of the multiple rotating bars 301 are rotatably connected to the inner walls of the base plate 1. L-shaped blocks 302 are slidably connected to adjacent sides of the multiple rotating bars 301. A support plate 303 is rotatably connected to the bottom end of the L-shaped blocks 302. A rotating plate 304 is rotatably connected to the outer wall of the rotating bars 301. A connecting block 305 is rotatably connected to adjacent sides of the multiple rotating plates 304. Pulling the rotating bars 301 causes the rotating plates 304 to rotate, thereby driving the connecting blocks 305 to move to the bottom until the rotating plates 304 are at a horizontal angle. A fixing bolt 306 is threadedly connected to the inner wall of the rotating bars 301. Rotating the fixing bolt 306 releases the fixing between the rotating bars 301 and the L-shaped blocks 302. Then, as needed, the L-shaped blocks 302 are pulled out to the bottom. When the required length is reached, the mechanism is restarted. Rotate the fixing bolt 306 to fix the rotating bar 301 and the extended L-shaped block 302. The bottom end of the support plate 303 is fixedly connected to the suction cup 307, which better adsorbs the support plate 303 above the plane. The bottom center of the seat plate 1 is provided with a sliding component 308. The sliding component 308 includes multiple limiting rods 3081. The outer walls of the multiple limiting rods 3081 are respectively fixedly connected to the outer wall of the rotating bar 301. The inner wall of the L-shaped block 302 is provided with a slide rail 3082. The bottom center of the seat plate 1 is fixedly connected to a sliding groove 3083. The outer wall of the sliding groove 3083 is slidably connected to the inner wall of the connecting block 305. The mutual cooperation between the slide rail 3082 and the sliding groove 3083 makes the sliding of the rotating bar 301 and the L-shaped block 302 more convenient, while the limiting rods 3081 better restrict the movement direction of the connecting block 305.

[0036] Specifically, before use, first pull the rotating bar 301 to rotate, causing the rotating plate 304 to rotate, which in turn drives the connecting block 305 to move to the bottom until the rotating plate 304 is at a horizontal angle. At this time, rotate the fixing bolt 306 to release the fixing between the rotating bar 301 and the L-shaped block 302. Then, pull the L-shaped block 302 to the bottom as needed. When the required length is reached, rotate the fixing bolt 306 again to fix the rotating bar 301 and the extended L-shaped block 302, thus completing the height adjustment. The suction cup 307 is used to better adhere the support plate 303 to the plane. At the same time, the cooperation between the slide rail 3082 and the slide groove 3083 makes the sliding of the rotating bar 301 and the L-shaped block 302 more convenient, while the limiting rod 3081 better restricts the movement direction of the connecting block 305.

[0037] Reference Figure 3 , Figure 5 and Figure 6A limiting cylinder 10 is fixedly connected to the rear top of the grooved platform disk 4. The limiting cylinder 10 can provide vertical limiting and support for the column 6. A limiting disk 9 is fixedly connected to the bottom of the outer wall of the column 6. The limiting disk 9 can prevent the column 6 from being over-inserted into the limiting cylinder 10. A concave block 11 is fixedly connected to the left side of the outer wall of the upper clamping block 805. The concave block 11 can drive the upper clamping block 805 to perform opening and closing movements to realize the clamping and releasing operation of the sample cell. Wear-resistant arc plates 12 are fixedly connected to the adjacent sides of the inner walls of the lower clamping block 804 and the upper clamping block 805. The wear-resistant arc plates 12 can fit tightly with the outer wall of the sample cell to increase the contact area between the sample cell and the sample cell.

[0038] Specifically, the limiting cylinder 10 provides vertical limiting and support for the column 6, ensuring that the column 6 will not shift or wobble after installation, making the entire fixed bracket structure more stable in the vertical direction, thus providing a reliable support foundation for the sample cell and ensuring the positional accuracy of the sample cell in the fixed state. When the column 6 is inserted into the limiting cylinder 10, the limiting plate 9 can fit tightly with the top end face of the limiting cylinder 10, preventing the column 6 from being over-inserted into the limiting cylinder 10. At the same time, it further enhances the stability of the connection between the column 6 and the grooved platform plate 4 in the horizontal direction, limiting the displacement of the column 6 in the horizontal direction. Furthermore, the concave block 11 can drive the upper clamping block 805 to open and close, realizing the clamping and releasing operation of the sample cell, thus facilitating the installation and disassembly of the sample cell. Meanwhile, the wear-resistant arc plate 12 can fit tightly with the outer wall of the sample cell, increasing the contact area between the plate and the sample cell, thereby dispersing the clamping force and preventing the sample cell from being damaged due to excessive local force.

[0039] Working principle: First, the sample cell is placed above the grooved platform disk 4. By rotating the rotating block 5, the hollow bevel gear ring 201 rotates synchronously. Under the meshing action of the hollow bevel gear ring 201 and multiple bevel gears 203, the threaded rod 202 rotates accordingly, causing the sliding block 204 with the outer threaded connection to slide in the limiting groove 2062 on the inner wall of the grooved platform disk 4. The cooperation between the limiting strip 2061 and the limiting groove 2062 restricts the movement trajectory of the sliding block 204, ensuring that it moves in a straight line. The movement of the sliding block 204 then drives the clamping block 205 to move, so as to achieve the initial clamping of the sample cell. Next, the column 6 is rotated and fixedly connected to the top of the grooved platform disk 4. For the fixed bracket assembly 7, the fastening screws are tightened. Bolt 703 to move the movable clamping block 704 closer to the arc-shaped block 702, clamp the column 6 in the middle of the U-shaped block 701, and then fix the limiting ring 705 at the required height to provide a placement position for the detection instrument. Then, using the adjusting component 8, slide the sliding hollow block 801 above the column 6 to the required position, and then rotate the adjusting nut 802 to fix the moved position. As needed, slide the sliding rod 803 out of the sliding hollow block 801, and after sliding out the required length, rotate the corresponding adjusting nut 802 to fix it. Place the detection instrument to be used between the lower clamping block 804 and the upper clamping block 805, and clamp and fix it under the action of the return spring 806, thereby quickly completing the clamping and fixing of the sample cell.

[0040] Furthermore, by using the telescopic mechanism 3, the rotating bar 301 is pulled to rotate, causing the rotating plate 304 to rotate accordingly, thereby driving the connecting block 305 to move to the bottom. When the rotating plate 304 reaches the horizontal position, the rotating fixing bolt 306 is tightened to release the fixed state between the rotating bar 301 and the L-shaped block 302. As needed, the L-shaped block 302 is pulled down to the required length, and then the fixing bolt 306 is tightened again to re-fix the rotating bar 301 and the extended L-shaped block 302 to complete the height adjustment. In addition, by using the suction cup 307, the support plate 303 can be more effectively adsorbed onto the plane. The cooperation between the slide rail 3082 and the slide groove 3083 ensures that the sliding of the rotating bar 301 and the L-shaped block 302 is smoother, while the limiting rod 3081 helps to limit the movement direction of the connecting block 305, thereby adjusting the height of the bracket as needed.
