Detailed Description
As shown in fig. 2, this embodiment provides a centrifuge tube cap opener, this cap opener is applicable to centrifuge tube uncapping, especially miniature centrifuge tube, replaces traditional manual uncapping.
The centrifuge tube cap opener comprises a tube body clamping assembly and a cap opening assembly; the pipe body clamping assembly is used for clamping a pipe body, so that liquid in the pipe body is prevented from being poured out due to the fact that a centrifugal pipe slides down due to reasons such as hand sliding after the pipe body clamping assembly is opened; the scissors comprise two clamping rods 11, the two clamping rods 11 are hinged to form a scissors structure, particularly, the middle parts of the clamping rods 11 are hinged through shafts or pins, the clamping parts can be forced to be close to or far away through handheld parts after the clamping rods are hinged, and the principle of the scissors is similar to that of scissors; the hinged parts of the two clamping rods 11 are provided with C-shaped hinged grooves, the C-shaped hinged grooves are hinged through shafts or pins after being matched with each other, so that the clamping parts of the two clamping rods 11 are parallel and level, the structure of the clamping rod is similar to that of a fire tongs, the force acting on a tube body is more uniform, the clamping rods 11 are provided with arc-shaped clamping parts 12, the arc-shaped clamping parts 12 are matched with the tube wall of a centrifugal tube, and when the clamping rods 11 are in a clamping state, the centrifugal tube can be clamped and cannot fall off; the rubber soft cushion is arranged on the clamping surface of the arc-shaped clamping part 12, so that the friction force between the arc-shaped clamping part 12 and the tube body can be increased, the damage of the hard clamping rods 11 to the tube body can be reduced, and the tube body of the centrifugal tube is protected; the rubber cushion is fixed at the arc-shaped clamping part 12 by means of glue and the like.
The cover opening assembly is used for opening a cover body of the centrifugal tube and comprises a connecting rod 21 and a cover opening sheet 22; the one end of connecting rod 21 is articulated, articulated accessible axle or round pin hinge, also can be through ball hinge, articulated back fixed mounting open cover plate 22, open cover plate 22 fixed mounting in a connecting rod 21 or fixed mounting two the articulated department of connecting rod 21, two the connecting rod 21 other end with clamping rod 11 is connected and is located the one end of arc clamping part 12, connects for perpendicular ball hinge, promptly connecting rod 21 and clamping rod 11's pole length place face mutually perpendicular. The utility model discloses a cover plate, including clamping rod 11, connecting rod 22, connecting rod 21, connecting rod 22 and lid, clamping rod 11 is close to each other (clamping state), and connecting rod 21 other end is in articulated state, and consequently connecting rod 21 installs the one end of opening cover plate 22 and the high increase of clamping rod 11 place face, and then changes open cover plate 22's position, according to showing in fig. 2, just open cover plate 22 and upwards (the direction of lid) the removal, remove the in-process, form the resistance between cover plate 22 and the lid, last upwards, the lid is backed down, and then realizes uncapping, open cover plate 22 and the face of lid contact are uncapping portion, open the lid for the plane and be equipped with the rubber cushion.
Connecting rod 21 preferentially articulates the one end that is close to handheld portion in arc clamping part 12, and the experimenter of being convenient for like this observes body clamping component and uncaps the harmony between the subassembly, improves the effect of uncapping.
During the use, the centrifuge tube is fixed through hand or test-tube rack, the handheld cap opener of experimenter, the body centre gripping subassembly of cap opener is in the detached state, be located body department with arc clamping part 12, it is located the lid below to open cover plate 22, hand action power is on body centre gripping subassembly, 12 centre gripping bodys of arc clamping part, the lid is opened to the ascending jack-up lid of piece 22, open the lid, then put the centrifuge tube in the test tube in addition, open body centre gripping subassembly, the action of next uncapping. It should be noted that the experimenter uses probably need practise several times and seeks the harmony of body centre gripping subassembly and the subassembly of uncapping, and the experimenter finds suitable position very easily after several times, can improve the effect of uncapping.
