Description

Technical Field

[0001] This utility model relates to the field of sample tube transfer, and in particular to a sample tube transfer device. Background Technology

[0002] In soil testing, since it is difficult to analyze soil samples on-site, it is necessary to transport soil samples collected on-site to the laboratory or to transport empty sample tubes from the laboratory to the field for soil collection. In other words, sample tube transportation serves as a bridge connecting on-site sampling and the laboratory.

[0003] Current conventional transfer devices typically have vias inside a housing to hold one sample tube, which is then transferred via a transport tray. However, this method can only transfer sample tubes of the same size at a time. For sample tubes of different sizes (e.g., different tube heights), different transfer devices are required, resulting in a significant waste of vias and consequently, wasted transfer space. Therefore, a new transfer device is needed to transport sample tubes. Utility Model Content

[0004] The purpose of this utility model is to provide a sample tube transfer device that can adapt to the transfer of sample tubes of various specifications, in order to address the problems mentioned above.

[0005] The technical solution adopted by this utility model is as follows: A sample tube transfer device includes a box and a cover plate. The box has multiple tube holes, and the axis of each tube hole is along the height direction of the box. A sliding plate is slidably connected inside the tube hole. A spring is provided between the sliding plate and the bottom of the tube hole. One end of the spring is fixed to the bottom of the tube hole, and the other end of the spring is fixed to the lower end face of the sliding plate. Support rods are fixed on both sides of the box. The support rods are arranged along the height direction of the box. A crossbeam is provided between the two support rods. The two ends of the cover plate are slidably connected to the two support rods respectively. The cover plate is positioned above the box in space. A driving mechanism for driving the cover plate to slide along the support rods is provided between the cover plate and the crossbeam.

[0006] Furthermore, the driving mechanism is a screw threadedly connected to the crossbeam, the axis of which is along the height direction of the housing, and one end of the screw is rotatably connected to the cover plate.

[0007] Furthermore, a rotating handle is connected to the other end of the screw.

[0008] Furthermore, the surface of the skateboard is provided with a first rubber layer that can elastically deform.

[0009] Furthermore, the bottom of the cover plate is provided with a second rubber layer that can be elastically deformed.

[0010] Furthermore, a sealing groove is provided on the top of the box, the sealing groove surrounds the internal space of the box, and a sealing ring is installed in the sealing groove.

[0011] Furthermore, the holes are distributed on the box in a rectangular array.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0013] This invention incorporates a spring within the tube hole. After the box is closed by the cover plate, the spring is compressed and deformed to generate elastic force. This elastic force causes the top of all sample tubes to abut against the cover, and the spring fills the space between the bottom of the sample tube and the bottom of the tube hole, thus accommodating sample tubes of different heights and achieving the purpose of transporting sample tubes of different specifications.

[0018] In the description of this specification, it should be noted that if terms such as "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," or "outer" appear to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, they are only for the convenience of describing this specification and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this specification.

[0019] Furthermore, the use of terms such as "horizontal" or "vertical" in this specification does not imply that the component must be absolutely horizontal or suspended, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal relative to "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0020] In the description of this specification, it should also be noted that, unless otherwise expressly specified and limited, the terms “set up,” “install,” “connect,” and “link” should be interpreted broadly. For example, a link can be a fixed link, a detachable link, or an integral link; it can be a mechanical link or an electrical link; it can be a direct link or an indirect link through an intermediate medium; it can be a connection within two components.

[0021] Example 1

[0022] like Figures 1-2 As shown, a sample tube transfer device includes a housing 1 and a cover plate 5. The housing 1 has multiple tube holes 11, and the axis of each tube hole 11 is along the height direction of the housing 1. A sliding plate 3 is slidably connected inside the tube hole 11. A spring 2 is provided between the sliding plate 3 and the bottom of the tube hole 11. One end of the spring 2 is fixed to the bottom of the tube hole 11, and the other end of the spring 2 is fixed to the lower end face of the sliding plate 3. Support rods 71 ​​are fixed on both sides of the housing 1. The support rods 71 ​​are arranged along the height direction of the housing 1. A crossbeam 72 is provided between the two support rods 71. The two ends of the cover plate 5 are slidably connected to the two support rods 71 ​​respectively, and the cover plate 5 is positioned above the housing 1 in space. A driving mechanism is provided between the cover plate 5 and the crossbeam 72 to drive the cover plate 5 to slide along the support rods 71.

[0023] In this embodiment, the sliding plate 3 transmits the elastic force of the spring 2 to the sample tube while isolating the spring 2 from the sample tube, preventing the spring 2 from scratching the sample plate surface. The drive mechanism drives the cover plate 5, which closes the box 1 during transport, preventing contamination of the sample tube and constraining the top of the sample tube, thus limiting its movement. The specific working principle of the transport device provided in this embodiment is as follows.

[0024] Sample tubes of the same or different specifications are placed one by one into the tube hole 11. The cover plate 5 is driven by the drive mechanism to move towards the box body 1 until the lower surface of the cover plate 5 contacts the upper surface of the box body 1. At this time, the cover plate 5 contacts the top of all the sample tubes. Due to the pushing action of the cover plate 5, each sample tube exerts a squeezing effect on the spring 2. The spring 2 deforms and has an elastic force. This elastic force keeps the top of the sample tube in contact with the cover plate 5 and the bottom of the sample tube in contact with the slide plate 3. The compressed spring 2 fills the space between the bottom of the sample tube and the bottom of the tube hole 11, so as to accommodate the placement of sample tubes of different heights and thus achieve the purpose of transporting sample tubes of different specifications.

[0025] It should be noted that, for this transfer device, since the spring 2 has a buffering performance, external vibrations will not cause excessive damage to the sample tube. Furthermore, under the elastic force of the spring 2, the sample tube can be kept in a state where the top is in contact with the cover plate 5 and the bottom is in contact with the slide plate 3, that is, the position of the sample tube is stable.

[0026] Example 2

[0027] Based on Example 1, further feasible implementation methods are proposed.

[0028] In one feasible implementation, the driving mechanism is a screw 8 threadedly connected to the crossbeam 72. The axis of the screw 8 is along the height direction of the housing 1. One end of the screw 8 is rotatably connected to the cover plate 5 through a bearing. That is, one end of the screw 8 is fixedly connected to the inner ring of the bearing, and the cover plate 5 is fixedly connected to the outer ring of the bearing, so that the screw 8 can rotate along its own axis, and the cover plate 5 will not rotate with the screw 8. By rotating the screw 8, the connection position between the cover plate 5, the screw 8 and the crossbeam 72 is adjusted, thereby changing the state of the cover plate 5 closing the housing 1 and opening the housing 1.

[0029] It should be noted that the cover plate 5 moves along the height direction of the box body 1 to achieve the closing and opening of the box body 1. Compared with other structures that close and open the box body 1 (such as the cover plate 5 being rotatably connected to the box body 1, and the closing and opening of the box body 1 being achieved by rotating the cover plate 5), it only has a pushing effect on the sample tube along the height direction of the box body 1, and no pushing effect in other directions (such as the width or length direction). Therefore, after the sample tube comes into contact with the cover plate 5, the contact position will not change, effectively avoiding friction between the top of the sample tube and the cover plate 5, as well as the bending torque on the sample tube, thus preventing damage to the sample tube.

[0030] It should be noted that the threaded connection ensures the stability of the connection between the screw 8 and the crossbeam 72, thus improving the positional stability of the cover plate 5.

[0031] In one feasible implementation, the other end of the screw 8 is connected to a rotating handle to facilitate the rotation of the screw 8.

[0032] In one feasible implementation, the surface of the slide plate 3 is provided with a first rubber layer 4 that can be elastically deformed. The first rubber layer 4 can be made of sponge. After the sample tube is subjected to the elastic force of the deformation of the spring 2, the bottom of the sample tube will be embedded in the first rubber layer 4. The first rubber layer 4 deforms and wraps around the bottom of the sample tube, restricting the bottom of the sample tube from swinging within the tube hole 11.

[0033] In one feasible implementation, a second rubber layer 6 that can be elastically deformed is provided at the bottom of the cover plate 5. The function and principle of the second rubber layer 6 are the same as those of the first rubber layer 4, except that the second rubber layer 6 wraps around the top of the sample tube and restricts the top of the sample tube from swinging at the contact position with the cover plate 5.

[0034] It should be noted that the first rubber layer 4 and the second rubber layer 6 respectively wrap around the top of the sample tube, restricting the bottom and top of the sample tube respectively, thereby constraining the entire sample tube and improving the positional stability of the sample tube.

[0035] It should be noted that the first rubber layer 4 and the second rubber layer 6 are provided so that both can provide cushioning when the cover plate 5 closes the box 1 and when the box 1 is opened. When the cover plate 5 closes the box 1, this cushioning prevents the cover plate 5 from suddenly contacting the sample tube and causing the sample tube to be impacted and damaged. When the cover plate 5 opens the box 1, if the cover plate 5 suddenly leaves and the elastic force of the spring 2 is suddenly released, this cushioning can reduce the possibility of the sample tube being thrown up.

[0036] In one feasible implementation, a sealing groove is provided on the top of the box 1, the sealing groove surrounds the internal space of the box 1, and a sealing ring 9 is installed in the sealing groove. When the cover plate 5 closes the box 1, the cover plate 5 and the box 1 squeeze the sealing ring 9 to improve the sealing performance of the box 1.

[0037] In one feasible implementation, the holes 11 are distributed in a rectangular array on the box 1, so that the upward force on the cover plate 5 is evenly distributed.

[0038] This invention is not limited to the specific embodiments described above. This invention extends to any new feature or combination disclosed in this specification, as well as any new method or process step or combination disclosed herein.
