Description

Technical Field

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

[0002] With the continuous development of society and the economy, people's awareness of environmental protection is also increasing. However, environmental pollution still exists in actual production operations, and water pollution is a typical example. After sampling the resources, they need to be transported to relevant departments for testing, thus requiring a convenient transportation device.

[0003] For example, Chinese Patent Publication No. CN220501391U discloses a sample transport device for environmental testing, which has a placement rack installed on the inner wall of the transport box; the clamping mechanism is installed on the inner wall of the placement rack, and the clamping mechanism includes a sorting block, a spring, a clamping block, a slot, a sampling tube, and a sealing cap. The sample transport device for environmental testing provided by this utility model solves the problem that in some current environmental testing sample transport devices, sample reagent bottles may shake during transportation, but the shock-absorbing cotton can only protect them and cannot fix them. If the sample reagent bottles shake continuously, the bottles may be bumped and broken, or water samples may leak, affecting the test results.

[0004] The existing technology has the following problems: When fixing the sample, the operator needs to insert the clamps between the two clamps step by step, which is quite troublesome. Secondly, during the sample transfer process, the transfer box is not protected against bumps or impacts, which can easily cause the internal container to fall off or be damaged.

[0011] Preferably, each of the four rollers has a mounting groove on its inner wall top, and each of the four mounting grooves has a locking block slidably connected to its inner wall. The lower ends of the four adjacent locking blocks are engaged unidirectionally with the outer surfaces of the four ratchet wheels on opposite sides. Each of the four locking blocks has two springs fixedly installed at its upper end, and the upper ends of the eight springs are fixedly connected to the top of the inner wall of the four mounting grooves.

[0027] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0028] like Figure 1 , Figure 2 and Figure 3 As shown, an environmental testing sample transfer device includes a movable transfer box 1, a box door fixedly installed on the front side of the transfer box 1, a buffer assembly 2 fixedly installed on the bottom of the inner wall of the transfer box 1, a fixing assembly 3 fixedly installed on the upper end of the buffer assembly 2, and protective assemblies 4 fixedly installed on the front and rear parts of the fixing assembly 3.

[0029] The buffer assembly 2 converts the force experienced by the transport box 1 during movement into the elastic potential energy of the buffer spring 25, thereby protecting the containers to be transported inside. The damper 212, ratchet 29, and locking block 210 work together to reduce the reciprocating frequency of the buffer spring 25 when it returns to its original position, preventing excessive vibration of the buffer plate 21 and the glass container. The fixing assembly 3 secures the sample containers to be transported, preventing damage during transport. The protective assembly 4 protects the outer surface of the containers when they are secured, extending their lifespan.

[0030] like Figure 4 As shown, the buffer assembly 2 includes a buffer plate 21. The front and rear parts of the left and right sides of the buffer plate 21 are slidably connected to the bottom of the left and right sides of the inner wall of the transfer box 1. Slide rods 22 are fixedly installed on the front and rear parts of the bottom of the inner wall of the transfer box 1. Sliding blocks 23 are slidably connected to the left and right parts of the outer walls of the two slide rods 22. Rotating rods 24 are rotatably connected to the upper ends of the four sliding blocks 23. The ends of the four adjacent rotating rods 24 away from the four sliding blocks 23 are rotatably connected to the front and rear parts of the lower end of the buffer plate 21.

[0031] By sliding the buffer plate 21 up and down, the buffer plate 21 pushes or pulls the four rotating rods 24. The four adjacent rotating rods 24 push the four adjacent sliders 23 to slide on the two sliding rods 22, so that the four adjacent sliders 23 move away from or closer to each other.

[0032] like Figure 4As shown, buffer springs 25 are movably sleeved on the left and right sides of the outer walls of the two slide rods 22. The opposite ends of the four adjacent buffer springs 25 are fixedly connected to the side of the four adjacent sliders 23 that are far apart from each other. The ends of the four adjacent buffer springs 25 that are far apart from each other are fixedly connected to the side of the outer walls of the two slide rods 22 that are far apart from each other.

[0033] During movement, the four sliders 23 compress or stretch the buffer springs 25, converting the force on the transport box 1 during bumps into the elastic potential energy of the buffer springs 25, which can effectively protect the transported sample containers.

[0034] like Figure 4 and Figure 5 As shown, each of the four sliders 23 has a fixed shaft 26 at its lower end. Each of the four shafts 26 has a roller 27 rotatably connected to the middle of its outer wall. Each of the four shafts 26 has a ratchet 29 fixedly sleeved on its middle of its outer wall. The four ratchet 29 are located in the inner cavity of the four rollers 27. The teeth on the outer surfaces of the four adjacent ratchet 29 are in opposite directions.

[0035] The movement of the four sliders 23 causes the corresponding rollers 27 to rotate. Since the four adjacent sliders 23 are always close to or far apart, the ratchet 29 must have opposite teeth on its outer surface to lock the rollers 27.

[0036] like Figure 4 and Figure 6 As shown, each of the four rollers 27 has a mounting groove 28 on its inner top. Each of the four mounting grooves 28 has a slidably connected locking block 210. The lower ends of the four adjacent locking blocks 210 are engaged unidirectionally with the outer surfaces of the four ratchet wheels 29 on opposite sides. Each of the four locking blocks 210 has two springs 211 fixedly installed on its upper end. The upper ends of the eight springs 211 are fixedly connected to the top of the inner walls of the four mounting grooves 28. Each of the four corners of the lower end of the buffer plate 21 has a damper 212 fixedly installed. The lower ends of the four dampers 212 are fixedly connected to the four corners of the bottom of the inner wall of the transfer box 1.

[0037] When the four adjacent sliders 23 move away from each other, the corresponding rollers 27 are in a rolling state, and the corresponding locking blocks 210 engage with the four ratchet wheels 29 and slide up and down in the mounting groove 28 through the spring 211. When the four adjacent sliders 23 move closer to each other, the four rollers 27 are locked by the cooperation of the corresponding locking blocks 210 and ratchet wheels 29, so that the rollers 27 slide on the bottom of the inner wall of the transfer box 1, increasing the frictional resistance and cooperating with the four dampers 212 to prevent the buffer plate 21 from vibrating frequently.

[0038] like Figure 7As shown, the fixing component 3 includes a reverse double threaded rod 31. The front and rear parts of the outer wall of the reverse double threaded rod 31 are rotatably connected to the front and rear positions of the upper left part of the buffer plate 21. An adjusting block 32 is fixedly installed at the front end of the reverse double threaded rod 31. A moving plate 33 is threadedly connected to both the front and rear parts of the outer wall of the reverse double threaded rod 31.

[0039] By rotating the reverse double threaded rod 31 through the adjusting block 32, the two moving plates 33 are moved closer or further apart.

[0040] like Figure 7 As shown, limit rods 34 are fixedly installed on the left and right sides of the upper end of the buffer plate 21. Fixing plates 35 are fixedly installed on the front and rear sides of the outer walls of the two limit rods 34. The left ends of the two fixing plates 35 are fixedly connected to the right ends of the two moving plates 33.

[0041] The two fixed plates 35 slide on the two limiting rods 34 by the movement of the two movable plates 33, and the two limiting rods 34 limit the movement of the two fixed plates 35.

[0042] like Figure 8 As shown, the protective component 4 includes several arc-shaped fixing blocks 42. Several spring guide shafts 41 are fixedly installed on the upper and lower parts of the opposite sides of the two fixing plates 35. The opposite ends of several adjacent spring guide shafts 41 are fixedly connected to the opposite sides of several adjacent arc-shaped fixing blocks 42. Rubber pads 43 are fixedly installed on the opposite sides of several adjacent arc-shaped fixing blocks 42.

[0043] The sample vessel is fixedly clamped between two adjacent arc-shaped fixing blocks 42, and the rubber pad 43 and several spring guide shafts 41 can protect the vessel from damage.

[0044] The working principle of this invention is as follows: The operator opens the box door and places the containers to be transported between several adjacent arc-shaped fixing blocks 42. Rotating the adjusting block 32 causes the reverse double-threaded rod 31 to rotate. Two moving plates 33, threadedly connected to the reverse double-threaded rod 31, move closer together. The two moving plates 33 then move the two fixing plates 35 closer together, causing the several adjacent arc-shaped fixing blocks 42 to move closer together, clamping and fixing the corresponding sample bottles. Several spring guide shafts 41 and corresponding rubber pads 43 protect the surface of the containers, extending their service life. After securing the containers, the box door is closed.

[0045] When the transport box 1 is subjected to bumps or impacts, the buffer plate 21 vibrates and presses the corresponding slider 23 through the rotating rod 24, so that the four buffer springs 25 are simultaneously subjected to the pressure of the four sliders 23. The four adjacent sliders 23 move away from each other, and the four sliders 23 drive the rollers 27 to rotate away. When the force disappears instantaneously, the elastic restoring force of the four buffer springs 25 pushes the four adjacent sliders 23 to move closer to each other. The four rollers 27 are jammed by the ratchet 29 and cannot maintain the rolling state, so the four rollers 27 slide on the bottom of the inner wall of the transport box 1. The above phenomenon, together with the four dampers 212, can reduce and absorb the elastic potential energy when the four buffer springs 25 push back, and prevent the buffer plate 21 from driving several sample vessels to vibrate back and forth.

[0046] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
