[0034] In order to make the objectives, technical solutions and advantages of the present disclosure more clear, the embodiments of the present disclosure will be further described in detail below with reference to the accompanying drawings.
[0035] The disclosed embodiment provides a test tube drain rack, Figure 1 For the structural schematic diagram of the test tube drain rack, see Figure 1 In this embodiment, the test tube drain rack includes a base 10 and a plurality of supporting structures 20.
[0036] Multiple support structures 20 are located on the same surface of the base 10 and are arranged at intervals from each other. The support structure 20 includes a support rod 210 and an elastic tray 220. The first end of the support rod 210 is connected to the base 10. The elastic tray 220 is sleeved outside the support rod 210 and is close to the first end of the support rod 210. The elastic expansion and contraction direction of the elastic tray 220 is consistent with the length direction of the support rod 210. The elastic tray 220 is connected to the base 10.
[0037] By using the test tube drain rack provided by the embodiment of the present disclosure, when draining and drying the test tube, the test tube is turned upside down on the support rod 210, and the second end of the support rod 210 can support the bottom of the test tube. Since the first end of the support rod 210 has an elastic tray 220, the elastic tray 220 can support the tube mouth of the test tube. In addition, since the elastic tray 220 itself is elastic and can be extended and retracted along the length direction of the support rod 210, the elastic tray 220 can be adaptively extended and retracted under the pressure of the test tube, thereby supporting test tubes of various length specifications.
[0038] That is to say, the test tube drain rack provided in the embodiment of the present disclosure can support both the bottom and the mouth of the test tube, effectively preventing the test tube from shaking due to insufficient support and eliminating the risk of collision and damage to adjacent test tubes.
[0039] In this embodiment, the second end of the support rod 210 has a buffer member 240 , and a surface of the buffer member 240 facing away from the support rod 210 is arc-shaped.
[0040] By providing the buffer 240 at the second end of the support rod 210, the bottom of the test tube can be prevented from directly contacting the second end of the support rod 210, thereby protecting the bottom of the test tube. In addition, since the side of the buffer 240 facing away from the support rod 210 is the side that directly contacts the bottom of the test tube, it is provided in an arc shape, which can further ensure the protection effect on the test tube.
[0041] As can be seen from the foregoing, the elastic tray 220 plays a key role in supporting the test tube. The elastic tray 220 is introduced below.
[0042] In this embodiment, the elastic pallet 220 includes a pallet ring 221 and an elastic member 222. The pallet ring 221 is movably mounted outside the support rod 210. One side of the pallet ring 221 is connected to the elastic member 222. The elastic member 222 is connected to the base 10 at a portion away from the pallet ring 221.
[0043] In the above implementation, the tray ring 221 is an annular structural member, and the support rod 210 is inserted into the inner hole of the tray ring 221 to realize the movable assembly between the tray ring 221 and the support rod 210. The elastic member 222 is respectively connected to the tray ring 221 and the base 10, thereby realizing the elastic connection between the tray ring 221 and the base 10. If the test tube is long, the elastic member 222 is compressed, and the tray ring 221 moves toward the base 10, so as to adapt to the longer test tube. On the contrary, if the test tube is short, the elastic member 222 is relaxed and stretched, and the tray ring 221 moves away from the base 10, so as to adapt to the shorter test tube.
[0044] Exemplarily, the elastic member 222 is a coil spring, and the elastic member 222 is sleeved outside the support rod 210 . The elastic member 222 and the tray ring 221 are coaxial with the support rod 210 .
[0045] In the above implementation, the support rod 210 , the pallet ring 221 and the elastic member 222 are all coaxially arranged, which can ensure that the elastic member 222 firmly supports the pallet ring 221 , so that the pallet ring 221 moves along the length direction of the support rod 210 .
[0046] Exemplarily, the elastic member 222 is a disc spring, and the configuration of the disc spring is similar to that of the coil spring, which will not be described in detail here.
[0047] Figure 2 This is a cross-sectional view of the test tube drain rack, combined with Figure 2 In this embodiment, the tray ring 221 has a receiving groove 223 on one side facing away from the elastic member 222. The receiving groove 223 is annular and arranged circumferentially along the support rod 210. The bottom of the receiving groove 223 has a plurality of leakage holes 224, and the plurality of leakage holes 224 are arranged at intervals along the circumference of the receiving groove 223.
[0048] In the above implementation, the receiving groove 223 is used to receive the tube mouth of the test tube, thereby further ensuring that the tray ring 221 firmly supports the test tube. Since the bottom of the receiving groove 223 is provided with a leakage hole 224, the water flowing down in the test tube can flow out from the leakage hole 224, thereby preventing water from accumulating in the receiving groove 223.
[0049] It is worth noting that the width of the accommodating groove 223 corresponds to the wall thickness of the test tube. In order to accommodate test tubes of various sizes, the width of the accommodating groove 223 should be designed to be larger. In this way, the accommodating groove 223 can accommodate both smaller test tubes and larger test tubes, thereby improving the versatility of the test tube drain rack.
[0050] Exemplarily, the notch edge of the receiving groove 223 has a chamfer 226 , and the chamfer 226 is arranged along the circumference of the receiving groove 223 .
[0051] In the above implementation, the chamfer 226 can guide the mouth of the test tube to a certain extent, so that the mouth of the test tube can smoothly enter the receiving groove 223, avoiding the collision between the mouth of the test tube and the edge of the receiving groove 223, thereby protecting the test tube.
[0052] Exemplarily, the chamfer 226 is in an arc shape, so as to further protect the tube opening of the test tube.
[0053] Continue to see Figure 2 In this embodiment, the side of the tray ring 221 facing away from the elastic member 222 has a buffer pad 225 , the buffer pad 225 is located at the bottom of the receiving groove 223 , the buffer pad 225 is annular, and the buffer pad 225 is arranged along the circumference of the receiving groove 223 .
[0054] In the above implementation, the buffer pad 225 is disposed at the bottom of the receiving groove 223 to prevent the tube mouth of the test tube from directly contacting and colliding with the bottom of the receiving groove 223, thereby further protecting the tube mouth of the test tube.
[0055] It is worth noting that the buffer pad 225 should avoid blocking the leakage hole 224, so as to ensure that the leakage hole 224 can leak normally. For example, the buffer pad 225 is a mesh structure, so that the water flow can flow out from the hollow part of the buffer pad 225.
[0056] Continue to see Figure 2 In this embodiment, a guide structure 230 is provided between the inner peripheral wall of the pallet ring 221 and the outer peripheral wall of the support rod 210. The guide structure 230 includes a guide groove 231 and a guide protrusion 232. The length direction of the guide groove 231 is consistent with the length direction of the support rod 210. One of the guide groove 231 and the guide protrusion 232 is located on the inner peripheral wall of the pallet ring 221, and the other of the guide groove 231 and the guide protrusion 232 is located on the outer peripheral wall of the support rod 210.
[0057] In the above implementation, under the action of the guide structure 230 , the guide groove 231 and the guide protrusion 232 cooperate with each other to ensure that the tray ring 221 always moves along the length direction of the support rod 210 .
[0058] In this embodiment, the base 10 includes a drain seat 110 and a water receiving tray 120 . The drain seat 110 is located in the water receiving tray 120 . The drain seat 110 has a plurality of drain through holes 111 arranged at intervals.
[0059] In the above implementation, the drain seat 110 is used to provide an installation base for the support structure 20, so that the support structure 20 can be stably installed on the base 10. The water flowing down from the support structure 20 flows to the water receiving tray 120 through the drain through hole 111, and the water receiving tray 120 can hold the water flowing down from the drain seat 110 to prevent the water from overflowing.
[0060] Exemplarily, the drainage holes 111 are arranged circumferentially along their corresponding support rods 210 .
[0061] Such arrangement of the drainage holes 111 can ensure that the water flowing down the support rod 210 is quickly drained to the water receiving tray 120, thereby avoiding the problem of water accumulation.
