Description

Technical Field

[0001] This utility model relates to the field of chip detection, and more particularly to a device for fixing a protein detection chip. Background Technology

[0002] Protein chips, also known as protein arrays, are a high-throughput protein function analysis technology. They involve immobilizing known protein molecules onto a solid support through special chemical treatment, then capturing the target protein that specifically binds to it. After washing and purification, confirmation and biochemical analysis are performed, providing strong technical support for obtaining important life information.

[0003] In protein chip technology, fixation devices play a crucial role. For example, a fixation device for RNA and protein detection chips disclosed in CN221822193U uses a compression spring sleeved on the outer side of one end of a positioning slide rod to limit the connection between the limiting clamp and the side plate, while also enabling the limiting clamp to have self-adaptive clamping and fixing capabilities. This facilitates elastic clamping of the RNA and protein detection chips that need to be fixed. By rotating the adjusting screw installed at one end of the adjusting arm, the clamping distance between the two sets of limiting clamps can be adjusted a second time according to the size and specifications of the RNA and protein detection chips, thereby improving the practicality of this fixation device in the field of detection chip fixation technology.

[0004] However, the device has some shortcomings. Although the clamping distance between the limiting clamps can be adjusted according to the size of the chip being detected, it cannot meet the clamping requirements of chips with different thicknesses, and its adaptability is insufficient. It can only move the optical detector downward by setting an electric push rod, which cannot achieve a higher degree of freedom of movement for the optical detector and does not have a stronger practicality.

For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0025] A preferred embodiment of the protein detection chip fixing device provided by this utility model is, for example... Figures 1 to 4 The image shows a device for fixing a protein detection chip, comprising a table body 1, a table platform 5 fixedly connected to the top of the table body 1, a placement platform 2 fixedly mounted on the top of the table platform 5, two clamping components 3 fixedly mounted on both sides of the top of the table platform 5, and a moving mechanism 4 located at the rear of the top of the table platform 5. The placement platform 2 is made of glass and contains a lighting component. This provides illumination for the protein detection chip, facilitating better observation and detection by the optical detector 406.

[0026] In this embodiment, the clamping component 3 includes a cylinder 301. One end of the cylinder 301 is fixedly connected to a support block 302, which is fixedly connected to the top of the table 5. The telescopic end of the cylinder 301 passes through the interior of the support block 302 and is slidably connected to it. A spring 305 is fixedly connected to the telescopic end of the table 1. A clamping plate 304 is fixedly connected to the side of the spring 305 away from the telescopic end of the cylinder 301. Two first telescopic rods 303 are fixedly connected between the clamping plate 304 and the support block 302. The two first telescopic rods 303 are connected to the cylinder 301. The telescopic ends are symmetrically distributed on both sides of the center. The clamping plate 304 includes an L-shaped clamping block 3045, which is slidably connected to the surface of the placement platform 2. A first sliding groove 3044 is provided on one side of the L-shaped clamping block 3045. An upper clamping block 3042 is slidably connected to the inner wall of the first sliding groove 3044. A threaded rod 3043 is threaded through and threadedly connected to the inside of the upper clamping block 3042. The upper and lower ends of the threaded rod 3043 pass through the inside of the L-shaped clamping block 3045 and are rotatably connected to the inside of the L-shaped clamping block 3045. A knob 3041 is fixedly connected to the top of the threaded rod 3043.

[0027] Through the above scheme, the clamping components 3 on both sides extend the telescopic end of the cylinder 301, so that the L-shaped clamping blocks 3045 on both sides slide along the top of the placement platform 2 to clamp the chip. During this process, the spring 305 plays a buffering role, and the first telescopic rods 303 on both sides make the sliding of the spring 305 more stable. After the initial clamping is completed, the knob 3041 is turned. Since the upper clamping block 3042 is threadedly connected to the threaded rod 3043, the upper clamping block 3042 can slide up and down along the surface of the first sliding groove 3044, and will clamp chips of different thicknesses.

[0028] In this embodiment, the moving mechanism 4 includes a motor 401, which is fixedly connected to one side of the rear end of the table 5. The driving end of the motor 401 passes through the interior of the table 5 and is rotatably connected to the interior of the table 5. A lead screw 402 is fixedly connected to the driving end of the motor 401. The end of the lead screw 402 away from the motor 401 passes through the interior of the table 5 and is rotatably connected to the interior of the table 5. A first slider 403 is threaded onto the surface of the lead screw 402. The first slider 403 is slidably connected to the inner wall of the table 5. A support column 411 is fixedly connected to the top of the first slider 403. A second electric actuator assembly 408 is fixedly provided at the top of the support column 411. The telescopic end of the second electric actuator assembly 408 passes through the top of the support column 411 and is slidably connected to the top of the support column 411. The telescopic end of the push rod assembly 408 is fixedly connected to a second slider 409. The support column 411 has a second groove 410 through it. The second slider 409 is slidably connected to the inner wall of the second groove 410. A first electric push rod assembly 407 is fixedly installed on one side of the second slider 409. A connecting block 404 is fixedly connected to the telescopic end of the first electric push rod assembly 407. Two second telescopic rods 412 are fixedly connected between the connecting block 404 and the second slider 409. The two second telescopic rods 412 are symmetrically distributed on both sides of the first electric push rod assembly 407 with the first electric push rod assembly 407 as the center. A sleeve 405 is fixedly connected to the side of the connecting block 404 away from the telescopic end of the first electric push rod assembly 407. An optical detector 406 is fitted on the inner wall of the sleeve 405.

[0029] Through the above scheme, the motor 401 is started, and the drive end of the motor 401 rotates, causing the lead screw 402 to rotate. Since the lead screw 402 is internally threaded with the first slider 403, the first slider 403 will slide along the inside of the table 5, causing the optical inspection instrument 406 to slide towards both sides of the device. The second electric push rod assembly 408 is started, and its telescopic end drives the second slider 409 to slide on the inner wall of the second slide groove 410, causing the optical inspection instrument 406 to move up and down. The extension and retraction of the telescopic end of the first electric push rod assembly 407 causes the connecting block 404 to drive the clamp 405, thereby the clamp 405 drives the optical inspection instrument 406 to move along the front and back direction of the device. The second telescopic rods 412 on both sides make the movement of the connecting block 404 more stable. The combined action of the motor 401, the second electric push rod assembly 408 and the first electric push rod assembly 407 gives the optical inspection instrument 406 a higher degree of freedom of movement. It should be noted that the optical inspection instrument 406 is located above the placement stage 2 so that it will not exceed the range when using the optical inspection instrument 406 to inspect the chip.

[0030] Working principle: When operating and using this utility model, as follows... Figures 1 to 4As shown, during use, the protein chip is placed on the top of the placement stage 2. The clamping components 3 on both sides are activated, causing the telescopic ends of the cylinder 301 to extend. This allows the L-shaped clamping blocks 3045 on both sides to slide along the top of the placement stage 2, clamping the chip. During this process, the spring 305 acts as a buffer, and the first telescopic rods 303 on both sides make the sliding of the spring 305 more stable. After initial clamping, the knob 3041 is rotated. Since the upper clamping block 3042 is threadedly connected to the threaded rod 3043, the upper clamping block 3042 can slide up and down along the surface of the first sliding groove 3044, clamping chips of different thicknesses. After clamping, the motor 401 is started. The drive end of the motor 401 rotates, driving the lead screw 402 to rotate. Because the lead screw 402 and... The first slider 403 has an internal threaded connection, so it slides along the inside of the table 5, causing the optical detector 406 to slide towards both sides of the device. The second electric push rod assembly 408 is activated, and its telescopic end drives the second slider 409 to slide along the inner wall of the second slide groove 410, causing the optical detector 406 to move up and down. The telescopic end of the first electric push rod assembly 407 causes the connecting block 404 to drive the clamp 405, which in turn drives the optical detector 406 to move along the front and back of the device. The second telescopic rods 412 on both sides make the movement of the connecting block 404 more stable. The combined action of the motor 401, the second electric push rod assembly 408, and the first electric push rod assembly 407 gives the optical detector 406 a higher degree of freedom of movement.

[0031] The above are merely illustrative embodiments of this utility model and are not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to the points of this utility model.
