Technical Field

[0001] The utility model relates to a microorganism sampling tool, belonging to the technical field of microorganism environment detection. Background Art

[0002] In the field of microbial sampling, traditional sampling tools often suffer from complex operation, limited sampling area, large storage space, and inconvenient post-sampling processing. Most traditional sampling tools use a single sampling tray, which not only cannot flexibly adjust the sampling area but also takes up a large space when carrying and storing, causing numerous inconveniences during sampling. Furthermore, the sampling tray is susceptible to contamination during collection and transportation, affecting the accuracy of sampling results. To address these issues, a microbial sampling tool was proposed. Utility Model Content

[0003] The purpose of the present invention is to provide a microbial sampling tool to solve the problems raised in the above background technology.

[0004] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a microbial sampling tool, comprising:

[0005] Two bottom bars are arranged in parallel, and one end of the two bottom bars is fixedly connected to a cross bar;

[0006] A fixed rod, the fixed rod being fixed to an end of the bottom rod away from the cross rod;

[0007] A movable rod is slidably connected to the bottom rod, and the fixed rod, movable rod and cross rod are arranged in parallel;

[0008] Multiple frames are connected in rotation in sequence, and the sides of the two frames at the end are hinged on the fixed rod and the movable rod respectively;

[0009] Wherein, each frame is provided with a plate;

[0010] When the movable rod moves closer to the fixed rod, the multiple frames fold and the dishes are folded together;

[0011] When the movable rod moves away from the fixed rod, the multiple frames unfold and move, and the dishes are laid flat.

[0012] Preferably, the frame includes a first frame body and a second frame body, and the second frame body is rotatably connected to the first frame body through a connecting plate;

[0013] The sides of the first frames on the two end portions are hinged to the fixed rod and the movable rod respectively, and the dish is arranged on the first frame, and the second frame is provided with a dish cover for covering the dish.

[0014] Preferably, a sliding plate is provided in both the first frame and the second frame, and a sliding groove for inserting the side edges of the sliding plate is provided on the inner walls of both sides of the first frame and the second frame, the dish is arranged in the middle of the sliding plate located on the first frame, and the dish cover is arranged in the middle of the sliding plate located on the second frame.

[0015] Preferably, a fixing rod is fixedly connected to the side wall of the cross rod, a push-pull rod is slidably connected inside the fixing rod, one end of the push-pull rod passes through the fixing rod and extends to the outside, and the other end of the push-pull rod passes through the fixing rod and is fixed to the side wall of the moving rod.

[0016] Preferably, the ends of the fixing rod and the push-pull rod are fixedly connected to handles.

[0017] Preferably, a collar is provided on the side wall of each second frame body, a through hole is formed on the collar, and a toggle rod is sleeved inside the through hole.

[0018] Preferably, the end of the toggle rod is provided with an external thread, and the through hole close to the fixed rod is provided with an internal thread that matches the external thread provided on the end of the toggle rod.

[0019] Preferably, permanent magnets are fixedly connected to opposite side walls of the first frame and the second frame. When the first frame and the second frame are folded together, the permanent magnets on the first frame and the second frame are attracted to each other.

[0020] Compared with existing technologies:

[0021] 1. The utility model adopts two parallel bottom bars and a cross bar structure fixed at one end, which not only ensures the overall stability and balance during operation, but also provides a basis for the subsequent folding and unfolding functions. The movable rod slidably connected to the bottom bar cooperates with the fixed fixed rod, so that multiple frames can be folded and unfolded smoothly. Each frame is provided with a plate, which not only makes full use of the space, but also maximizes the sampling area, thereby improving the sampling efficiency. When the movable rod moves close to the fixed rod, the multiple frames fold and the plates fit tightly together, greatly saving storage space. When the movable rod moves away from the fixed rod, the frame slowly unfolds, and the plates are flattened, realizing the collection of sedimentation bacteria.

[0022] 2. The utility model uses a rotational connection between the first frame and the second frame to allow each frame to be flexibly folded and unfolded. At the same time, the dish cover on the second frame can effectively protect the dish and prevent it from being contaminated during collection and transportation. When the device needs to be taken out of the isolated environment, it is only necessary to simply fold the second frame and the first frame in half to achieve sealed protection of the dish. Subsequently, through the relative movement of the movable rod and the fixed rod, multiple frames can be quickly folded, greatly reducing the size of the tool and making it easier to carry and store. In addition, the design of the sliding plate and the slide groove allows the dish and the dish cover to be easily removed, which not only facilitates the post-sampling processing work, but also increases the reuse rate of the tool and greatly improves work efficiency.

[0039] The present invention is described below with reference to specific embodiments, but is not intended to limit the present invention.

[0040] Example 1

[0041] like Figures 1-8 As shown, in this embodiment, a microbial sampling tool is provided, comprising two parallel bottom bars 1, one end of each bottom bar 1 being fixedly connected to a cross bar 101; a fixed bar 2 being fixed to one end of each bottom bar 1 away from the cross bar 101; a movable bar 3 being slidably connected to each bottom bar 1, the fixed bar 2 and the movable bar 3 being arranged parallel to the cross bar 101; a plurality of frames 4 being arranged above each bottom bar 1, the plurality of frames 4 being rotatably connected in sequence, as shown in FIG. Figure 2 As shown, two adjacent frames 4 are connected by hinges 12, and the hinges 12 on both sides of the same frame 4 rotate in opposite directions, causing the multiple frames 4 to fold or unfold in an M shape, and the side edges of the two frames 4 at the end are hinged on the fixed rod 2 and the movable rod 3 respectively; wherein, each frame 4 is provided with a dish 5; when the movable rod 3 moves close to the fixed rod 2, the multiple frames 4 fold and the dish 5 are folded together; when the movable rod 3 moves away from the fixed rod 2, the multiple frames 4 unfold and the dish 5 is flat.

[0042] like Figure 4-Figure 5 As shown, in order to enable the first frame body 401 and the second frame body 402 to be firmly folded together, permanent magnets 11 are fixedly connected to the opposite side walls of the first frame body 401 and the second frame body 402. When the first frame body 401 and the second frame body 402 are folded together, the permanent magnets 11 on the first frame body 401 and the permanent magnets 11 on the second frame body 402 are attracted to each other.

[0043] Example 2

[0044] like Figures 1-6 As shown, based on the first embodiment, the frame 4 of this embodiment includes a first frame body 401 and a second frame body 402, and the second frame body 402 is rotatably connected to the first frame body 401 through a connecting plate 405;

[0045] Combine Figure 2 、 Figure 3 One side of the connecting plate 405 is rotatably connected to the side wall of the first frame 401 , and the other side of the connecting plate 405 is rotatably connected to the side wall of the second frame 402 . The second frame 402 can be rotated to the bottom of the first frame 401 through the connecting plate 405 .

[0046] The sides of the first frame 401 on the two frames 4 at the end are hinged to the fixed rod 2 and the movable rod 3 respectively, and the dish 5 is set on the first frame 401, and the dish cover 6 for covering the dish 5 is set on the second frame 402.

[0047] like Figure 3 As shown, when the second frame 402 is rotated to the bottom of the first frame 401 (in order to show the rotation state of the second frame 402, Figure 3 The state shown is the state in which the second frame 402 has not been rotated into place. When the second frame 402 is rotated to fit under the first frame 401, the dish 5 is in an open state, and the dish cover 6 is inverted and hidden under the first frame 401. At this time, the device is placed in an area with cleanliness requirements (such as an isolator, honeycomb incubator, or mobile incubator) for collecting sedimentation bacteria.

[0048] The process of taking out the dish from the area with clean requirements is as follows: first, fold the second frame 402 and the first frame 401 together, so that the dish cover 6 covers the dish 5 (as shown in FIG. Figure 2 As shown), the movable rod 3 is driven to move toward the fixed rod 2, and the relative position between the movable rod 3 and the fixed rod 2 is continuously reduced, so that the multiple frames 4 are folded. When the multiple frames 4 are folded together, the unfolded volume of the multiple frames 4 can be effectively reduced, making it convenient to take them out from the isolated environment.

[0049] like Figure 5-Figure 6 As shown, in order to enable the dish 5 and the dish cover 6 on the first frame 401 and the second frame 402 to be removed, a sliding plate 403 is provided in the first frame 401 and the second frame 402, and a sliding groove 404 for inserting the side of the sliding plate 403 is provided on the inner walls of both sides of the first frame 401 and the second frame 402. The dish 5 is set in the middle of the sliding plate 403 located on the first frame 401, and the dish cover 6 is set in the middle of the sliding plate 403 located on the second frame 402.

[0050] The sliding plate 403 is detachably mounted on the first frame 401 and the second frame 402 via the sliding groove 404 , so that the dish 5 and the dish cover 6 can be removed.

[0051] In order to drive the frame 4 to fold and unfold, a fixed rod 7 is fixedly connected to the side wall of the cross bar 101, and a push-pull rod 8 is slidably connected to the inside of the fixed rod 7. One end of the push-pull rod 8 passes through the fixed rod 7 and extends to the outside, and the other end of the push-pull rod 8 passes through the fixed rod 7 and is fixed on the side wall of the movable rod 3.

[0052] The ends of the fixed rod 7 and the push-pull rod 8 are fixedly connected to handles. When driving the frame 4 to fold and unfold, hold the handles on the fixed rod 7 and the push-pull rod 8 with both hands respectively, and then push and pull the push-pull rod 8 to make the push-pull rod 8 slide inside the fixed rod 7. The push-pull rod 8 can then lead the movable rod 3 to slide on the bottom rod 1, thereby driving the frame 4 to fold and unfold.

In this state, the toggle rod 10 can be inserted into the through hole 901, and the fixing rod 7 is used to fix the cross bar 101 and the bottom bar 1, that is, the first frame 401 is fixed. Then, the toggle rod 10 is used to rotate the second frame 402 to drive the dish cover 6 to open and close. When the multiple frames 4 need to be folded, the toggle rod 10 can be pulled out from the through hole 901 of the ring 9.

[0056] An external thread is provided at the end of the toggle rod 10, and an internal thread that is compatible with the external thread provided at the end of the toggle rod 10 is provided in the through hole 901 near the fixed rod 2. After the external thread on the toggle rod 10 is engaged with the internal thread in the through hole 901, the toggle rod 10 and the ring 9 can be fixed as a whole, and the second frame 402 can be better driven to rotate by the toggle rod 10, thereby better driving the opening and closing of the dish cover 6.
