Technical Field
[0001] This utility model relates to the technical field of sample collection devices, specifically a sample collection device. Background Technology
[0002] A physical examination, also known as a medical check-up, physical examination, or health check-up, is a method by which doctors use their senses, examination instruments, and laboratory equipment to directly or indirectly examine a patient's physical condition. Its purpose is to collect objective data about the patient's health and to detect and prevent potential diseases as early as possible.
[0003] After blood is drawn during a physical examination, the test tubes containing the blood samples need to be collected and stored. Existing storage devices usually place the samples in a storage box. However, when the test tubes are placed in the storage box, they are prone to shaking and collisions during transportation, which may cause the test tubes to break and affect the results of the physical examination. Utility Model Content
[0004] To address the shortcomings of existing technologies, this invention provides a sample collection device that solves the problem of test tube breakage caused by shaking during handling of the collection device.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A sample collection device includes a collection box, a placement rack slidably installed inside the collection box, a plurality of placement slots being provided on the placement rack, and a stabilizing device for preventing test tube breakage installed inside the collection box.
[0007] The stabilizing device includes a door rotatably mounted on a collection box, on which two sets of symmetrical rotating shafts are fixedly mounted. Each set of rotating shafts is fixedly mounted with a worm gear. Inside the collection box, two sets of symmetrical first rotating rods are rotatably mounted. One end of the first rotating rod is fixedly mounted with a worm wheel that meshes with the worm gear, and the other end of the first rotating rod is fixedly mounted with a first helical tooth.
[0008] Preferably, the collection box is rotatably mounted with two sets of second rotating rods, each set of second rotating rods is fixedly mounted with a threaded rod, and one end of the second rotating rod is fixedly mounted with a first helical tooth that meshes with the second helical tooth.
[0009] Preferably, four sets of symmetrical limiting rods are fixedly installed on the collection box. A limiting plate that is threadedly connected to the threaded rod is slidably installed on the limiting rod. A pressure plate that is slidably connected to the threaded rod is slidably installed on the limiting rod. A spring is sleeved on the limiting rod, and the two ends of the spring are fixedly connected to the pressure plate and the limiting plate.
[0010] Preferably, the collection box is equipped with a guiding device, which includes two sets of No. 1 guiding plates fixedly installed on the collection box, and two sets of symmetrical No. 2 guiding plates fixedly installed on the box door. Both the No. 1 and No. 2 guiding plates are provided with guiding grooves. The No. 1 guiding plate is provided with a sliding groove, and the No. 2 guiding plate is provided with a limiting groove.
[0011] Preferably, two sets of symmetrical connecting plates are fixedly installed on the placement rack, and two sets of symmetrical fixing plates are fixedly installed on the placement rack.
[0012] Preferably, the collection box is fixedly installed with two sets of symmetrical support bases.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. This utility model, through the setting of a stabilizing device, causes the rotating shaft to drive the threaded rod to rotate within the limiting plate by rotating the box door. This causes the limiting plate to move the pressure plate downward. Under the action of the spring, the pressure plate squeezes the plug at the top of the test tube, limiting the test tube. This not only prevents the liquid inside the test tube from flowing out, but also prevents the test tube from breaking due to shaking when handling the collection device.
[0015] 2. This utility model, through the setting of a guiding device, moves the placement rack out of the collection box. The connecting plate on the placement rack enters the guiding groove on the second guiding plate from the guiding groove on the first guiding plate, and the fixing plate moves out of the sliding groove and into the limiting groove. This allows the placement rack to be supported by the box door after it is moved out, avoiding the situation where the placement rack and test tubes will fall to the ground due to the lack of other support points after the placement rack is pulled out.

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.
[0023] Example 1
[0024] Reference Figures 1-4 This embodiment proposes a sample collection device. By setting a stabilizing device 2, the problem of test tube breakage caused by shaking during the handling of the collection device is solved. The device includes a collection box 1, on which two sets of symmetrical support bases 5 are fixedly installed. A placement rack 11 is slidably installed inside the collection box 1. Several sets of placement slots 12 are opened on the placement rack 11. A stabilizing device 2 for preventing test tube breakage is installed inside the collection box 1. The stabilizing device 2 limits the test tube and prevents the test tube from breaking during transportation.
[0025] The stabilizing device 2 includes a door 21 rotatably mounted on the collection box 1. Two sets of symmetrical rotating shafts 22 are fixedly mounted on the door 21, and a worm gear 23 is fixedly mounted on each set of rotating shafts 22. Two sets of symmetrical first rotating rods 24 are rotatably mounted inside the collection box 1. A worm wheel 25 meshing with the worm gear 23 is fixedly mounted at one end of the first rotating rod 24, and a first helical tooth 26 is fixedly mounted at the other end of the first rotating rod 24. Two sets of symmetrical second rotating rods 27 are rotatably mounted on the collection box 1, and a threaded rod 28 is fixedly mounted on each set of second rotating rods 27. A first helical tooth 26 meshing with a second helical tooth 29 is fixedly mounted at one end of the second rotating rod 27. Four sets of symmetrical limiting rods 3 are fixedly mounted on the collection box 1 to make the movement of the limiting plate 31 more stable. A limiting plate 31 threadedly connected to the threaded rod 28 is slidably mounted on the limiting rod 3. A spring 33 is fitted onto the pressure plate 32 and the limiting rod 3. The pressure of the spring 33 limits the test tube, and the two ends of the spring 33 are fixedly connected to the pressure plate 32 and the limiting plate 31. The rack 11 containing the test tube is placed into the collection box 1. The box door 21 is rotated, which causes the rotating shaft 22 to drive the worm gear 23 to rotate. The rotation of the worm gear 23 drives the first rotating rod 24 connected to the worm wheel 25 to rotate. The rotation of the first rotating rod 24 drives the first helical tooth 26 to rotate. The rotation of the first helical tooth 26 drives the second rotating rod 27 connected to the second helical tooth 29 to rotate. The rotation of the second rotating rod 27 drives the threaded rod 28 to rotate inside the limiting plate 31, which causes the limiting plate 31 to drive the pressure plate 32 to move downward. Under the action of the spring 33, the pressure plate 32 squeezes the plug at the top of the test tube, limiting the test tube. This not only prevents the liquid in the test tube from flowing out, but also prevents the test tube from breaking due to shaking when the collection device is moved.
[0026] Example 2
[0027] Based on Embodiment 1, the technical solution proposed in Embodiment 1 is used to solve the problem that the test tubes are prone to shaking when the collection device is handled, which may cause them to break. Since the rack can hold a large number of test tubes, the rack is heavy as a whole. When taking out the innermost test tubes, the rack needs to be completely pulled out. After the rack is pulled out, there are no other support points. Therefore, when the rack is pulled out, the rapid change in weight may cause the rack and test tubes to slip from your hands and fall to the ground.
[0028] Reference Figures 1-4The collection box 1 is equipped with a guiding device 4, which includes two sets of first guide plates 41 fixedly installed on the collection box 1, and two sets of second guide plates 42 symmetrically installed on the box door 21. Both the first guide plate 41 and the second guide plate 42 have guide grooves 43. The first guide plate 41 has a sliding groove 44, and the second guide plate 42 has a limiting groove 45. Two sets of symmetrical connecting plates 46 are fixedly installed on the placement frame 11. The connecting plates 46 can move within the guide grooves 43. Two sets of symmetrical fixing plates 47 are fixedly installed on the placement frame 11. When the box door 21 is closed, the second guide plate 42 will... The guide groove 43 and sliding groove 44 on the first guide plate 41 are blocked to prevent the placement rack 11 from shaking during the transportation of the collection box 1. The placement rack 11 is moved out of the collection box 1. The connecting plate 46 on the placement rack 11 enters the guide groove 43 on the second guide plate 42 from the guide groove 43 on the first guide plate 41. The fixing plate 47 moves out of the sliding groove 44 and enters the limiting groove 45, so that the placement rack 11 can be supported by the box door 21 after it is moved out. This avoids the situation where the placement rack 11 and the test tube will fall to the ground because there are no other support points after the placement rack 11 is pulled out.
