The collecting tube clamping mechanism according to the embodiment of the present utility model is described with reference to fig. 1 to 5.
As shown in fig. 1 to 5, the collecting tube gripping device according to the embodiment of the present utility model includes: a frame 100; the clamping pieces 200 are all fixed on the frame 100, the clamping pieces 200 comprise a first clamping piece 210 and a second clamping piece 220, the upper ends of the first clamping piece 210 and the second clamping piece 220 are connected through a fixing part 230, the first clamping piece 210 and the second clamping piece 220 are all in a semicircular column shape, the first clamping piece 210 and the second clamping piece 220 are coaxially arranged and jointly enclose a cylindrical cavity for accommodating the collecting tube 1, the first clamping piece 210 and the second clamping piece 220 are made of elastic materials, a gap is reserved between the first clamping piece 210 and the second clamping piece 220, an elastic ring 240 is sleeved outside the first clamping piece 210 and the second clamping piece 220, and the elastic ring 240 is used for mutually closing the first clamping piece 210 and the second clamping piece 220 to clamp the collecting tube 1.
As shown in fig. 1 to 5, eight clamping pieces 200 are arranged on the frame 100 in a penetrating manner along the up-down direction, the eight clamping pieces 200 are symmetrically arranged, and a rotating shaft of the mixing instrument is arranged on the frame 100 in a penetrating manner along the left-right direction to drive the frame 100 to turn over and vibrate, so that the collecting tube 1 clamped on the clamping pieces 200 turns over and vibrates, and the effect of mixing samples is achieved.
As shown in fig. 2 to 5, the clip 200 includes a first clip 210 with an opening facing rearward and a second clip 220 with an opening facing forward, the first clip 210 and the second clip 220 being coaxially disposed to enclose a cylindrical cavity accommodating the collection tube 1. A certain gap is formed between the first clamping piece 210 and the second clamping piece 220, the first clamping piece 210 and the second clamping piece 220 are elastic, the upper ends of the first clamping piece 210 and the second clamping piece 220 are connected together through the fixing part 230, the lower ends of the first clamping piece 210 and the second clamping piece 220 are sleeved with an elastic ring 240, the elastic ring 240 contracts towards the axis of the cylindrical cavity for accommodating the collecting tube 1, and the lower ends of the first clamping piece 210 and the second clamping piece 220 are close to each other, namely, the gap between the lower ends of the first clamping piece 210 and the second clamping piece 220 is smaller than the gap between the upper ends.
Thus, the diameter of the cylindrical cavity section gradually decreases from top to bottom, the collection tube 1 is inserted from top to bottom through the opening at the upper end of the cylindrical cavity, and the first clamping piece 210 and the second clamping piece 220 gradually clamp the collection tube 1 during the process of inserting the collection tube 1 downward. And because of the arrangement of the elastic ring 240, the lower end of the cylindrical cavity has elasticity, and the collection tube 1 is tightened and fixed towards the axle center through the first clamping piece 210 and the second clamping piece 220, so that the collection tube 1 in a certain size range can be adapted. Because the inner side walls of the first clamping piece 210 and the second clamping piece 220 are respectively matched with the shape of part of the outer wall of the collecting tube 1, and the first clamping piece 210 and the second clamping piece 220 are elastic, when the collecting tube 1 is clamped, the first clamping piece 210 and the second clamping piece 220 have larger contact areas with the collecting tube 1, so that larger friction force between the first clamping piece 210 and the second clamping piece 220 and the collecting tube 1 is ensured, the collecting tube 1 is prevented from falling out in the vibration and rotation process, and the tube wall breakage of the collecting tube 1 caused by too concentrated clamping force during clamping is avoided.
In some embodiments of the present utility model, the first and second clamping pieces 210 and 220 are provided with two annular protrusions 250 at the circumferential sides thereof, and the elastic ring 240 is provided between the two annular protrusions 250. Thereby preventing the elastic ring 240 from sliding up and down. It is conceivable that the recess 260 may be provided on the circumferential sides of the first and second clamping pieces 210 and 220, and the elastic ring 240 may be provided in the recess 260.
In the above-described embodiment, two elastic rings 240 are provided. The number of the elastic rings 240 may be three, four, five, etc., and it will be understood by those skilled in the art that by providing a plurality of elastic rings 240, the clamping force between the first clamping piece 210 and the second clamping piece 220 can be improved, and the problem that when one elastic ring 240 breaks, the clamping piece 200 loses the clamping force, so that the collecting tube 1 is separated can be avoided.
As shown in fig. 1 and 2, the fixing portion 230 is provided with two fixing holes 231 in the up-down direction, and the clip 200 is fixed to the frame 100 by the bolt fitting the fixing holes 231.
As shown in fig. 4 and 5, the lower ends of the first and second clamping pieces 210 and 220 are provided with a sealing bottom 270. The upper end of the sealing bottom 270 is provided with a transition part 271, and the shape of the transition part 271 is matched with the bottom of the collecting tube 1. When collection tube 1 is inserted downward to the bottom, the bottom of collection tube 1 abuts transition 271. The seal bottom 270 prevents the collection tube 1 from extending excessively downward, causing the collection tube 1 to collide with the apparatus during rotation. The transition portion 271 abuts against the bottom of the collection tube 1, and prevents the lower end of the collection tube 1 from shaking relative to the clamping piece 200 during rotation and vibration, so that the collection tube 1 is prevented from falling out.
The embodiments of the present utility model have been described in detail with reference to the accompanying drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
