DNA hybridization capture instrument carrying positioning assembly

Abstract

This invention provides a DNA hybridization capture device with a positioning component. The DNA hybridization capture device with a positioning component includes: a rectangular column; sliding components are installed on the outer walls of the left and right sides of the rectangular column; the sliding components are connected to a supporting component; the supporting component is connected to a clamping and positioning component; and the clamping and positioning component is connected to the capture device body. The DNA hybridization capture device with a positioning component provided by this invention allows the rotating shaft to rotate via a worm gear, which in turn drives a worm wheel to rotate. The worm wheel then moves a rectangular plate along a rack, allowing the capture device body to be moved to a suitable height to accommodate workers of different heights. The worm gear and worm wheel also provide a self-locking function when the handle is not rotated. When the capture device body is placed on the supporting plate, the output of the motor drives a bidirectional threaded rod to rotate, causing two sets of threaded blocks to simultaneously move the clamping plate towards the outer wall of the capture device body until the capture device body is stably clamped.

The DNA hybridization capture instrument carrying the positioning component includes: a rectangular column 1, with sliding components 3 installed on the outer walls of the left and right sides of the rectangular column 1, the sliding components 3 being connected to a support component 2, the support component 2 being connected to a clamping and positioning component 5, the clamping and positioning component 5 being connected to the capture instrument body 4, and an adjustment component 7 for moving the capture instrument body 4 up and down is installed between the support component 2 and the rectangular column 1, and the clamping and positioning component 5 is used to limit the shaking of the capture instrument body 4.

[0023] The sliding component 3 includes a slide groove 31. Two sets of slide grooves 31 are evenly opened on the outer walls of the left and right sides of the rectangular column 1. A slider 32 is slidably connected to the inner wall of each set of slide grooves 31. The outer walls of the two sets of sliders 32 are connected to the bearing component 2.

[0024] The support component 2 can move up and down along the slide groove 31 via the slider 32.

[0025] The bearing assembly 2 includes rectangular plates 22. Two sets of rectangular plates 22 are fixedly connected to the outer walls of two sets of sliders 32 respectively. Several sets of support columns 23 are fixedly installed on the top of each set of rectangular plates 22. A bearing plate 21 is fixedly installed between the tops of each set of support columns 23. The top of the bearing plate 21 is respectively equipped with the capture device body 4 and the clamping and positioning assembly 5. Strip plates 24 are fixedly installed on the outer walls of the support columns 23 located on the front and rear sides of the bearing plate 21. The two sets of strip plates 24 are connected to the adjustment assembly 7.

[0026] By adjusting component 7, the entire capture device body 4 on the carrier plate 21 can be moved up and down along the slide 31.

[0027] The adjusting assembly 7 includes a rack 73, which is fixedly connected to the front side wall of the rectangular column 1. A worm gear 72 is rotatably connected between the inner walls of the two sets of rectangular plates 22. The worm gear 72 is meshed with the rack 73. A rotating shaft 75 is rotatably connected through the side wall of the strip plate 24 located at the front end of the bearing plate 21. A handle 74 is fixedly installed on the outer wall of the front end of the rotating shaft 75. A worm 71 is fixedly installed at the rear end of the rotating shaft 75. The worm 71 is meshed with the worm gear 72.

[0028] When the handle 74 is turned, the shaft 75 will drive the worm wheel 72 to rotate through the worm 71. The worm wheel 72 will drive the rectangular plate 22 to move along the rack 73, thereby moving the capture device body 4 to a suitable height as needed. At the same time, the worm 71 and worm wheel 72 are designed to achieve a self-locking function when the handle 74 is not turned.

[0029] The clamping and positioning assembly 5 includes rectangular slots 55. Two sets of rectangular slots 55 are evenly opened on the top of the support plate 21.

[0032] The working principle of the DNA hybridization capture device with positioning component provided by this utility model is as follows: After the capture device body 4 is placed on the support component 2, it is stably restricted on the support component 2 by clamping and positioning component 5. Then, the capture device body 4 on the support component 2 is moved to a suitable height with the assistance of sliding component 3 by adjusting component 7, so that staff of different heights can use the capture device body 4.

[0033] Compared with related technologies, the DNA hybridization capture instrument with positioning component provided by this utility model has the following beneficial effects:

[0034] By turning the handle 74, the rotating shaft 75 will drive the worm wheel 72 to rotate through the worm 71. The worm wheel 72 will drive the rectangular plate 22 to move along the rack 73, thereby allowing the capture device body 4 to move to a suitable height to accommodate workers of different heights. At the same time, the worm 71 and worm wheel 72 can achieve a self-locking function when the handle 74 is not turned.

[0035] When the capture device body 4 is placed on the support plate 21, the output end of the motor 51 drives the bidirectional threaded rod 52 to rotate, so that the two sets of threaded blocks 54 drive the clamping plate 53 to move closer to the outer wall of the capture device body 4 at the same time, until the capture device body 4 is stably clamped.
