Abstract
Description
Technical Field
[0001] This utility model relates to the field of sampling tube technology, and in particular to a quick sampling tube fixing device. Background Technology
[0002] The rapid sampling tube fixing device is a tool used to quickly and efficiently fix sampling tubes, and is widely used in gas sampling, environmental monitoring, virus sampling, and other fields. Its main purpose is to improve sampling efficiency, ensure sampling quality, and enhance the safety and convenience of operation.
[0003] The standard sampling procedure requires the use of rapid hand sanitizer multiple times. However, when the rapid hand sanitizer is placed into the sampling tube after use, it often cannot dry completely. When the hand sanitizer is not dry, the friction between the hand and the sampling tube is reduced, making it more difficult for staff to open the sampling tube, thus increasing the difficulty of the work. Utility Model Content
[0004] To address the aforementioned problems, this invention provides a quick-fixing device for sampling tubes.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sampling tube quick fixing device, including a mounting plate, a fixing plate rotatably disposed on the upper surface of the mounting plate, a fixing hole penetrating through the upper surface of the fixing plate, a circular groove penetrating through the upper surface of the mounting plate, a circular ring rotatably disposed in the circular groove, the circular ring being fixed to the fixing plate, and a clamping device for clamping the sampling tube being disposed on the fixing plate.
[0006] By adopting the above technical solution, when staff need to fix the sampling tube, they simply place the sampling tube into the fixing hole. Then, the staff rotates the fixing plate; during this rotation, the clamping device secures the sampling tube. At this point, the staff can easily open the sampling tube. This process reduces the difficulty of opening the sampling tube and thus lowers the workload for the staff.
[0007] Furthermore, the outer wall of the fixed plate is provided with a circumferential array of multiple through slots, and the fixing holes are connected to the through slots. The clamping device includes multiple rotating shafts that are respectively fixed on the top wall and bottom wall of the multiple through slots, and multiple fixing members that are respectively sleeved on the outer wall of the multiple rotating shafts. The fixing members are rotatably connected to the rotating shafts, and the end of the fixing member away from the rotating shaft is slidably disposed on the upper surface of the mounting plate.
[0008] Furthermore, the upper surface of the mounting plate is circumferentially arrayed with multiple sliding seats with upper openings. The multiple sliding seats are fixed to each other with the mounting plate. Each of the multiple sliding seats has a sliding member slidably disposed therein. The multiple sliding members are respectively fixed to the ends of the multiple fixed members away from the rotation axis.
[0009] By adopting the above technical solution, when the operator rotates the fixed plate, the rotating shaft moves synchronously with the fixed plate under its action. At this time, the fixed component rotatably connected to the rotating shaft rotates relative to the rotating shaft, causing the end of the fixed component away from the rotating shaft to move. Since the end of the fixed component away from the rotating shaft is fixed to the sliding component, the sliding component slides along the sliding seat under the action of the fixed plate, thus causing the end of the fixed component away from the rotating shaft to move synchronously with the sliding seat. Figure 2 As shown, the rotating shaft and the fixing components are not coaxially designed, allowing multiple fixing components to be close together to secure the sampling tube inside the fixing hole. At this point, the operator can easily open the sampling tube, reducing the difficulty of opening the tube and thus simplifying the operator's work.
[0010] Furthermore, a guide rod is fixedly provided on the inner wall of the sliding seat, and the guide rod passes through the sliding member and is slidably connected to the sliding member.
[0011] By adopting the above technical solution, the guide rod reduces the probability of wobbling during the sliding process of the slider, thereby reducing the probability of the slider and the sliding seat separating from each other, thus improving the stability of the device.
[0012] Furthermore, an annular groove is formed on the inner wall of the circular groove, and an annular block is rotatably arranged in the annular groove, with the annular block and the circular ring being fixed to each other.
[0013] By adopting the above technical solution, when the fixed disk rotates, the ring rotates synchronously with the fixed disk under the action of the fixed disk, and then the ring block rotates synchronously with the ring under the action of the ring. During this process, the ring block limits the ring and the fixed disk, thereby reducing the probability of the ring and the fixed disk moving, thus improving the stability of the device.
[0014] Furthermore, a rubber ring is fitted on the outer wall of the annular block, and the rubber ring is fixed to the annular block.
[0015] By adopting the above technical solution, the rubber ring increases the friction between the annular block and the annular groove, thereby reducing the probability of the fixed plate rotating under external force after the sampling tube is fixed, thus improving the stability of the device.
[0016] Furthermore, a rocker arm is fixedly installed on the outer wall of the fixed disk.
[0017] By adopting the above technical solution, the rocker arm reduces the difficulty for workers to rotate the fixed plate, thereby reducing the difficulty of their work.
[0018] Furthermore, the upper surface of the mounting plate is provided with a circumferential array of multiple mounting holes.
[0019] By adopting the above technical solution, the installation block reduces the difficulty for workers to fix the installation plate, thereby reducing the difficulty of their work.
[0020] In summary, this utility model has the following beneficial effects:
[0021] 1. In this application, when the worker needs to fix the sampling tube, the worker needs to place the sampling tube into the fixing hole. Then, the worker rotates the fixing plate, and during the rotation of the fixing plate, the clamping device fixes the sampling tube. At this time, the worker can open the sampling tube. This process reduces the difficulty for the worker to open the sampling tube, thereby reducing the workload of the worker.
[0022] 2. In this application, when the operator rotates the fixed plate, the rotating shaft moves synchronously with the fixed plate under its action. At this time, the fixed component rotatably connected to the rotating shaft rotates relative to the rotating shaft, causing the end of the fixed component away from the rotating shaft to move. Since the end of the fixed component away from the rotating shaft is fixed to the sliding component, the sliding component slides along the sliding seat under the action of the fixed plate, thus causing the end of the fixed component away from the rotating shaft to move synchronously with the sliding seat. Figure 2 As shown, the rotating shaft and the fixing components are not coaxially designed, allowing multiple fixing components to be close together to secure the sampling tube inside the fixing hole. At this point, the operator can easily open the sampling tube, reducing the difficulty of opening the tube and thus simplifying the operator's work.
[0023] 3. In this application, the guide rod reduces the probability of wobbling during the sliding process of the slider, thereby reducing the probability of the slider and the sliding seat separating from each other, thus improving the stability of the device. Attached Figure Description

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0029] like Figure 1-3 As shown in the figure, this application discloses a sampling tube quick fixing device, including a mounting plate 1, a fixing plate 11, a ring 14, a clamping device 3, a sliding seat 4, and a sliding member 41. The mounting plate 1 has a circular plate structure with a vertical axis, and a circular groove 13 is formed through its upper surface. The fixing plate 11 is rotatably disposed on the upper surface of the mounting plate 1, with its axis coinciding with the axis of the mounting plate 1, and a fixing hole 12 is formed through its upper surface. The ring 14 is rotatably disposed in the circular groove 13, with its axis coinciding with the axis of the mounting plate 1, and the ring 14 is fixed to the fixing plate 11.
[0030] When staff need to secure the sampling tube, they must place it into the fixing hole 12. Then, the staff rotates the fixing plate 11; during this rotation, the clamping device 3 secures the sampling tube. At this point, the staff can open the sampling tube. This process reduces the difficulty of opening the sampling tube and thus lowers the workload for the staff.
[0031] Multiple through slots 2 are circumferentially arranged on the outer wall of the fixed disk 11, and the fixing holes 12 are interconnected with the through slots 2. A clamping device 3 is installed on the fixed disk 11 to clamp the sampling tube. The clamping device 3 includes a rotating shaft 31 and a fixing member 32. The rotating shaft 31 is a cylindrical rod structure with a vertical axis. Multiple rotating shafts 31 are provided and fixedly installed on the inner top and bottom walls of multiple through slots 2. Multiple fixing members 32 are provided and respectively sleeved on the outer wall of multiple rotating shafts 31. The fixing members 32 are rotatably connected to the rotating shafts 31, and the end of the fixing member 32 away from the rotating shaft 31 is slidably installed on the upper surface of the mounting disk 1.
[0032] Multiple sliding seats 4 are arranged in a parallel array on the upper surface of the mounting plate 1, and the multiple sliding seats 4 are fixed to the mounting plate 1. Multiple sliding members 41 are provided and are slidably disposed in the multiple sliding seats 4, and the multiple sliding members 41 are respectively fixed to the ends of the multiple fixing members 32 away from the rotation axis 31.
[0033] When the operator rotates the fixed disk 11, the rotating shaft 31 moves synchronously with the fixed disk 11 under its action. At this time, the fixed member 32, which is rotatably connected to the rotating shaft 31, rotates relative to the rotating shaft 31, causing the end of the fixed member 32 away from the rotating shaft 31 to move. Since the end of the fixed member 32 away from the rotating shaft 31 is fixed to the sliding member 41, the sliding member 41 slides along the sliding seat 4 under the action of the fixed disk 11, thus causing the end of the fixed member 32 away from the rotating shaft 31 to move synchronously with the sliding seat 4. Figure 2 As shown, the rotating shaft 31 and the fixing member 32 are not coaxially designed, thus allowing multiple fixing members 32 to approach each other and fix the sampling tube inside the fixing hole 12. At this point, the operator can open the sampling tube, which reduces the difficulty of opening the sampling tube and thus reduces the workload of the operator.
[0034] To improve the stability of the device, a guide rod 5 is fixedly installed on the inner wall of the sliding seat 4. The guide rod 5 passes through the sliding member 41 and is slidably connected to the sliding member 41. The guide rod 5 reduces the probability of the sliding member 41 shaking during sliding, thereby reducing the probability of the sliding member 41 separating from the sliding seat 4, thus improving the stability of the device.
[0035] To improve the stability of the device, an annular groove 6 is formed on the inner wall of the circular groove 13. An annular block 61 is rotatably disposed within the annular groove 6, and the annular block 61 is fixed to the circular ring 14. When the fixed disk 11 rotates, the circular ring 14 rotates synchronously with the fixed disk 11 under the action of the fixed disk 11. Consequently, the annular block 61 rotates synchronously with the circular ring 14 under the action of the circular ring 14. During this process, the annular block 61 limits the movement of the circular ring 14 and the fixed disk 11, thereby reducing the probability of movement of the circular ring 14 and the fixed disk 11, and thus improving the stability of the device.
[0036] To improve the stability of the device, a rubber ring 7 is fitted onto the outer wall of the annular block 61, and the rubber ring 7 is fixed to the annular block 61. The rubber ring 7 increases the friction between the annular block 61 and the annular groove 6, thereby reducing the probability of the fixed disk 11 rotating under external force after the sampling tube is fixed, thus improving the stability of the device.
[0037] To reduce the difficulty of the work for the staff, a rocker arm 8 is fixedly installed on the outer wall of the fixed plate 11. The rocker arm 8 reduces the difficulty for the staff to rotate the fixed plate 11, thereby reducing the difficulty of the work for the staff.
[0038] To reduce the difficulty of the work for the workers, multiple mounting holes 9 are arranged in a circular array on the upper surface of the mounting plate 1. The mounting block reduces the difficulty for the workers to fix the mounting plate 1, thereby reducing the difficulty of the workers' work.
[0039] The working principle of the sampling tube quick fixing device in this embodiment is as follows: When the operator needs to fix the sampling tube, the operator needs to place the sampling tube into the fixing hole 12. Subsequently, the operator rotates the fixing plate 11, thereby causing the rotating shaft 31 to move synchronously with the fixing plate 11 under the action of the fixing plate 11. At this time, the fixing member 32, which is rotatably connected to the rotating shaft 31, rotates relative to the rotating shaft 31, thereby causing the end of the fixing member 32 away from the rotating shaft 31 to move. Since the end of the fixing member 32 away from the rotating shaft 31 is fixed to the sliding member 41, the sliding member 41 slides along the sliding seat 4 under the action of the fixing plate 11, thereby causing the end of the fixing member 32 away from the rotating shaft 31 to move synchronously with the sliding seat 4. Figure 2 As shown, the rotating shaft 31 and the fixing member 32 are not coaxially designed, thus allowing multiple fixing members 32 to approach each other and fix the sampling tube inside the fixing hole 12. At this point, the operator can open the sampling tube, which reduces the difficulty of opening the sampling tube and thus reduces the workload of the operator.
[0040] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
