Description

Technical Field

[0001] The utility model relates to the technical field of clamping devices, in particular to a clamping device for an object to be tested. Background Art

[0002] Currently, the chemiluminescence immunoassay analyzer needs to add the test object into a transparent microplate for detection during the test process. When using the microplate, the microplate needs to be clamped and fixed.

[0003] For example, the patent number CN204065097U discloses a clamping device for a chemiluminescent immunoassay instrument, comprising a support plate, the upper surface of which is a smooth surface and is slidably provided with a first clamping member and a second clamping member, the first clamping member and the second clamping member having opposite surfaces respectively provided with a first clamping surface and a second clamping surface for clamping a microplate to be tested; the lower surface of the support plate is provided with a groove in the longitudinal direction, a slide plate is slidably provided in the groove, and a V-shaped slide groove is provided in the middle of the slide plate; and a first slide block and a second slide block. Although the clamping device for a chemiluminescent immunoassay instrument can better achieve the clamping and alignment of the microplate; however, the clamping device for a chemiluminescent immunoassay instrument has some shortcomings. In actual use, the slide plate slides longitudinally in the groove to achieve the clamping and loosening of the microplate. When the microplate is fixed, the slide block cannot be locked. If the operator accidentally touches the slide block, it is easy to cause the first clamping member and the second clamping member to move, thereby affecting the fixing effect of the microplate, so it needs to be improved.

Since the cavity 201 and the vertical rod 207 limit the adjustment block 202, the rotation of the threaded rod 208 can drive the adjustment block 202 to move up and down, thereby driving the clamping block to move up and down between adjacent limiting teeth 7;

[0035] The threaded rod 208 is rotatably mounted on the block 200 via a bearing, thereby preferably realizing the rotatable installation of the threaded rod 208 .

[0036] See also Figure 1-Figure 6 In this embodiment, a fixing ring 300 sleeved on the long rod 206 is provided in the cavity 205, an anti-dropping block 301 is provided at the end of the long rod 206 passing through the fixing ring 300, a stop block 302 is provided on the long rod 206, a telescopic spring 303 sleeved on the long rod 206 is provided between the stop block 302 and the fixing ring 300, a blocking cap 304 is provided at the open end of the cavity 205, and a round hole is provided on the blocking cap 304 for the long rod 206 to extend out, the blocking block includes an upper inclined block 400 and a lower inclined block 401, a connecting plate is provided between the upper inclined block 400 and the lower inclined block 401, an inclined surface 402 and a vertical surface 403 are provided on the blocking block, and the inclined surfaces 402 and the vertical surfaces 403 arranged on the upper inclined block 400 and the lower inclined block 401 are arranged in opposite directions.

[0037] In this embodiment, by setting the fixing ring 300, the anti-dropping block 301, the stopper 302 and the plugging cap 304, the fixing ring 300 is fixedly connected to the side wall of the cavity 205, the long rod 206 is slidably and telescopically connected to the fixing ring 300, the anti-dropping block 301 is fixedly connected to one end of the long rod 206, and there is a certain gap between the anti-dropping block 301 and the bottom wall of the cavity 205, so that the long rod 206 can slide and telescopically in the cavity 205, and the anti-dropping block 301 can prevent the long rod 206 from being separated from the telescopic spring 303, the stopper 302 is fixedly connected to the long rod 206, the stopper 302 is slidably connected to the inner wall of the cavity 205, and the plugging cap 304 is threadedly connected to the cavity 205, thereby facilitating the installation of components in the cavity 205;

[0038] Among them, through the arrangement of the telescopic spring 303, the upper inclined block 400, the lower inclined block 401, the inclined surface 402 and the vertical surface 403, when the clamping plates 4 are close to each other to clamp the microplate, the upper inclined block 400 is moved down to between the adjacent limiting teeth 7 by rotating the threaded rod 208. At this time, the first spring 102 pushes the clamping plate 4 to move, and the clamping plate 4 drives the upper inclined block 400 to move, so that the inclined surface 402 slides on the limiting teeth 7. The limiting teeth 7 can compress the long rod 206 to move by squeezing the inclined surface 402. The movement of the long rod 206 drives the stop block 302 to move. The stop block 302 compresses the telescopic spring 303 to make the long rod 206 retract into the cavity 205. As the first spring 102 continues to push the clamping plate 4 to move, the upper inclined block 400 can continue to slide between the limiting teeth 7. When the clamping plate 4 contacts the microporous plate, the first spring 102 no longer pushes the clamping plate 4 to move, and at the same time, the vertical surface 403 of the upper inclined block 400 contacts the side of the limiting tooth 7, and the telescopic spring 303 pushes the long rod 206 to extend from the cavity 205, and the long rod 206 drives the upper inclined block 400 to be clamped between two adjacent limiting teeth 7, so that the clamping plate 4 can be locked; when the microporous plate needs to be removed, the threaded rod 208 can be rotated to drive the lower inclined block 401 to move up between the limiting teeth 7. Since the inclined surfaces 402 and the vertical surfaces 403 on the upper inclined block 400 and the lower inclined block 401 are in opposite directions, at this time, the lower inclined block 401 can be driven to move between the limiting teeth 7 by pulling the pull cap 209, driving the clamping plates 4 away from each other, releasing the clamping fixation of the microporous plate, and the microporous plate can be removed.

[0039] Working principle: When the clamping device for the object to be tested is in use, the threaded rod 208 can be rotated by rotating the pull cap 209, driving the lower inclined block 401 to move up to between the limiting teeth 7, and the pull cap 209 is pulled to drive the lower inclined block 401 to move between the limiting teeth 7, so that the clamping plates 4 are separated from each other until the microporous plate can be placed between the clamping plates 4, and the microporous plate is placed between the clamping plates 4, and the threaded rod 208 is rotated to move the upper inclined block 400 down to between the adjacent limiting teeth 7, and the first spring 102 can push the clamping plate 4 to move, and the clamping plate 4 drives the upper inclined block 400 to slide continuously between the limiting teeth 7, and when the clamping plate 4 contacts the microporous plate, the microporous plate can be clamped and fixed.

[0040] In conclusion, the above is only a preferred embodiment of the present utility model, and all equivalent fixed connection changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
