Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical experimental equipment technology, specifically to an auxiliary device for fixing petri dishes in pharmaceutical experiments. Background Technology

[0002] In pharmaceutical experiments, petri dishes are essential experimental equipment. In pharmaceutical laboratories, petri dishes need to be stored in batches and processed subsequently, mainly involving two aspects: first, adding culture medium after arranging the petri dishes; second, placing the culture medium in batches into an incubator for incubation. To facilitate the fixation of the petri dishes, an auxiliary device for fixing petri dishes in pharmaceutical experiments is needed.

[0003] However, existing petri dish fixation devices used in pharmaceutical experiments have the following drawbacks:

[0004] (1) Existing auxiliary fixation devices for petri dishes in pharmaceutical experiments have weak functions in reducing the difficulty of operation and improving experimental efficiency. Due to the complexity of the operation process of traditional auxiliary fixation devices and the large number of steps, the operation is cumbersome and the efficiency is reduced.

[0005] (2) Existing auxiliary fixation devices for petri dishes in pharmaceutical experiments have weak functions in optimizing space utilization and improving the efficiency of batch operations. Because multiple small petri dishes are scattered on the operating table, they occupy too much space and cause the operating area to be crowded. Utility Model Content

[0006] The purpose of this invention is to provide an auxiliary fixation device for petri dishes in pharmaceutical experiments, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary fixing device for petri dishes in pharmaceutical experiments, comprising: a frame, a clamping assembly and an auxiliary assembly, wherein a telescopic rod is fixedly connected to the top of the frame, a spring is sleeved on the outer surface of the telescopic rod, a top plate is fixedly connected to the top of the telescopic rod, a limit rod is fixedly connected to one side of the bottom of the top plate, and a pressure plate is fixedly connected to the inner side wall of the top plate;

[0008] A fixing rod is fixedly connected to the inner top wall of the frame, and a placement frame is rotatably connected to the outer surface of the fixing rod. A placement slot is provided on the top of the placement frame, and a first magnetic suction component is fixedly connected to one side of the top of the placement frame. A second magnetic suction component is provided on the top of the first magnetic suction component, and a handle is fixedly connected to one side of the surface of the placement frame.

[0009] Optionally, the bottom of the spring is fixedly connected to the top of the frame, and the top of the spring is fixedly connected to the bottom of the top plate. Through the connection between the spring, the frame, and the top plate, the frame supports and fixes one end of the spring. When the spring extends or retracts, it will drive the top plate to move.

[0010] Optionally, a limiting slot is provided at the top of the frame, and the lower surface of the limiting rod is slidably connected to the inner wall of the limiting slot. When the top plate moves, it will drive the limiting rod to slide inside the limiting slot, and at the same time, the limiting slot limits the movement position of the limiting rod.

[0011] Optionally, the inner top wall of the frame is provided with a fixing slot, and the outer surface of the second magnetic component is connected to the frame through the fixing slot, thereby fixing the second magnetic component to the frame.

[0012] Optionally, the inner bottom wall of the frame is provided with a reserved groove to prevent positioning when placing the culture dish.

[0013] Optionally, an anti-slip pad is fixedly connected to the bottom of the pressure plate. The anti-slip pad is made of medical-grade silicone. The anti-slip pad can improve the stability of the device.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This auxiliary fixing device for petri dishes in pharmaceutical experiments, through the setting of the clamping components, when in use, pulling the top plate simultaneously causes the telescopic rod and spring to extend, and the limiting rod limits the movement position of the top plate. After the petri dish is placed in the gap between the top plate and the device, the top plate is released. At this time, the spring rebounds and causes the top plate to move downward, which in turn causes the pressure plate to press down on the petri dish, keeping the petri dish in a stable position. This achieves the effect of reducing the difficulty of operation and improving experimental efficiency, avoiding the situation where the operation process of traditional auxiliary fixing devices is complicated, with many steps, resulting in cumbersome operation and reduced efficiency.

[0016] 2. This auxiliary fixing device for petri dishes in pharmaceutical experiments, through the setting of the auxiliary group, allows the holder to rotate the placement frame by holding the handle, while the fixing rod limits the rotation position of the placement frame. Smaller petri dishes can be placed into the placement slot. After use, the placement frame is rotated in the reverse direction until the first magnetic suction component and the second magnetic suction component are attracted, so that the position of the placement frame is stable in the device, reducing the space occupied. This achieves the effect of optimizing space utilization and improving the efficiency of batch operation, avoiding the situation of placing multiple small petri dishes scattered on the operating table, occupying too much space and causing the operating area to be crowded.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 As shown, this utility model provides a technical solution: an auxiliary fixing device for petri dishes in pharmaceutical experiments, comprising: a frame 1, a clamping assembly 2, and an auxiliary assembly 3. A telescopic rod 201 is fixedly connected to the top of the frame 1. A spring 202 is sleeved on the outer surface of the telescopic rod 201. A top plate 203 is fixedly connected to the top of the telescopic rod 201. A limiting rod 204 is fixedly connected to one side of the bottom of the top plate 203. A pressure plate 205 is fixedly connected to the inner side wall of the top plate 203. Pulling the top plate 203 simultaneously causes the telescopic rod 201 and the spring 202 to extend, and the limiting rod 204 limits the movement position of the top plate 203. After the petri dish is placed in the gap between the top plate 203 and the device, the top plate 203 is released. At this time, the spring 202 rebounds and causes the top plate 203 to move downward, thereby causing the pressure plate 205 to press down on the petri dish and keep the position of the petri dish stable.

[0024] A fixing rod 301 is fixedly connected to the inner top wall of the frame 1. A placement frame 302 is rotatably connected to the outer surface of the fixing rod 301. A placement slot 303 is provided on the top of the placement frame 302. A first magnetic suction member 304 is fixedly connected to one side of the top of the placement frame 302. A second magnetic suction member 305 is provided on the top of the first magnetic suction member 304. A handle 306 is fixedly connected to one side of the surface of the placement frame 302. Holding the handle 306 drives the placement frame 302 to rotate. At the same time, the fixing rod 301 limits the rotation position of the placement frame 302. Smaller petri dishes can be placed into the placement slot 303. After use, the placement frame 302 is rotated in the opposite direction until the first magnetic suction member 304 and the second magnetic suction member 305 are attracted, so that the position of the placement frame 302 is stable in the device, reducing the space occupied.

[0025] The bottom of the spring 202 is fixedly connected to the top of the frame 1, and the top of the spring 202 is fixedly connected to the bottom of the top plate 203. Through the connection between the spring 202 and the frame 1 and the top plate 203, the frame 1 supports and fixes one end of the spring 202. When the spring 202 extends or retracts, it will drive the top plate 203 to move.

[0026] A limiting slot 4 is provided on the top of the frame 1. The lower surface of the limiting rod 204 is slidably connected to the inner wall of the limiting slot 4. When the top plate 203 moves, it will drive the limiting rod 204 to slide inside the limiting slot 4. At the same time, the limiting slot 4 limits the movement position of the limiting rod 204.

[0027] The inner top wall of the frame 1 is provided with a fixing slot 5. The outer surface of the second magnetic component 305 is connected to the frame 1 through the fixing slot 5. The fixing slot 5 connects and fixes the second magnetic component 305 to the frame 1.

[0028] The inner bottom wall of the frame 1 is provided with a reserved groove 6, which is used to prevent positioning when placing the culture dish;

[0029] The bottom of the pressure plate 205 is fixedly connected to an anti-slip pad 7, which is made of medical-grade silicone. The anti-slip pad 7 improves the stability of the device.

[0030] In this invention, the working steps of the device are as follows:

[0031] First step: Pull the top plate 203 to extend the telescopic rod 201 and spring 202, and limit the movement position of the top plate 203 with the limiting rod 204. After placing the culture dish in the gap between the top plate 203 and the device, release the top plate 203. At this time, the spring 202 rebounds and drives the top plate 203 to move downward, thereby driving the pressure plate 205 to press down on the culture dish and keep the position of the culture dish stable.

[0032] The second step: Hold the handle 306 to rotate the placement frame 302. At the same time, the fixing rod 301 limits the rotation position of the placement frame 302. Smaller petri dishes can be placed into the placement slot 303. After use, rotate the placement frame 302 in the opposite direction until the first magnetic suction member 304 and the second magnetic suction member 305 are attracted, so that the position of the placement frame 302 is stable in the device, reducing the space occupied.

[0033] The third step: The frame 1 and the top plate 203 are connected by the spring 202. The frame 1 supports and fixes one end of the spring 202. When the spring 202 extends or retracts, it will drive the top plate 203 to move. When the top plate 203 moves, it will drive the limiting rod 204 to slide inside the limiting slot 4. At the same time, the limiting slot 4 limits the movement position of the limiting rod 204. The fixing slot 5 connects and fixes the second magnetic suction component 305 to the frame 1. The reserved groove 6 prevents positioning when placing the culture dish. The anti-slip pad 7 can improve the stability of the device placement.
