Description

Technical Field

[0001] This utility model relates to the field of bacterial culture dish rack technology, and in particular to a bacterial culture dish rack with adjustable partition spacing. Background Technology

[0002] In bacterial culture experiments, bacterial culture dishes are crucial experimental instruments. They are mostly transparent, shallow dishes made of glass or plastic, and usually consist of a flat bottom and a snap-on lid. During bacterial culture experiments, racks are needed to store and place bacterial culture dishes.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: the fixed spacing of the partitions in existing bacterial culture dish racks makes it difficult to adapt to the placement needs of culture dishes of different sizes and quantities. When it is necessary to place large-sized culture dishes or a large number of small culture dishes, the fixed spacing of the partitions will limit the number of dishes that can be placed, resulting in low space utilization. For some special experiments, it is necessary to place different batches and types of culture dishes in layers. The fixed spacing of the partitions cannot be flexibly adjusted, which brings inconvenience to the experimental operation. Therefore, to address the above problems, an adjustable partition spacing bacterial culture dish rack is proposed. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing bacterial culture dish racks, which have fixed partition spacing, making it difficult to accommodate different sizes and quantities of culture dishes. When large culture dishes or a large number of small culture dishes need to be placed, the fixed spacing of the partitions limits the number that can be placed, resulting in low space utilization. Furthermore, for some special experiments that require different batches and types of culture dishes to be placed in layers, the fixed spacing of the partitions cannot be flexibly adjusted, causing inconvenience to experimental operations. Therefore, this invention proposes a bacterial culture dish rack with adjustable partition spacing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a bacterial culture dish rack with adjustable partition spacing, comprising two mounting racks, four shelves slidably connected to the inner walls of the two mounting racks, and adjustment devices provided on both sides of the four shelves. The adjustment devices include eight mounting blocks, which are arranged in pairs. The four sets of mounting blocks are fixedly connected to both sides of the four shelves respectively. Insertion holes are provided on the side of the two mounting racks that are far apart from each other. Insert rods are slidably inserted into the mounting blocks and are slidably connected to the inner walls of the insertion holes. A round rod is fixedly connected to one side of the mounting block, and an arc plate is slidably connected to the arc surface of the round rod. The arc plate is fixedly connected to one end of the insert rod.

[0006] The effect achieved by the above components is as follows: by setting up an adjustment device, the spacing between the shelves can be adjusted. By using the combination of structures such as mounting blocks, insert rods, round rods and arc plates, the insert rods can be inserted and removed in the insertion holes, making it easy to adjust the position of the shelves in the mounting frame, thereby flexibly changing the spacing between the shelves and improving the practicality and flexibility of the device.

[0007] Preferably, a stop block is fixedly connected to the end of the round rod away from the mounting block, the size of the insertion rod is adapted to the size of the insertion hole, and two baffles are fixedly connected to the upper surface of the shelf.

[0008] The effects achieved by the above components are as follows: the baffle can prevent the arc plate and the insert from detaching from the round rod, ensuring the structural stability of the adjustment device and ensuring normal adjustment operation; the baffle on the shelf can prevent the petri dish from slipping, improving the safety of placement.

[0009] Preferably, a spring is fitted onto the arc surface of the round rod, and the two ends of the spring are fixedly connected to the stop block and the arc plate, respectively.

[0010] The effect achieved by the above components is that when the insertion rod is aligned with the insertion hole, the elastic force of the spring will drive the arc plate to move forward, thereby driving the insertion rod to automatically insert into the inner wall of the insertion hole, which improves the convenience of the device.

[0011] Preferably, a threaded rod is fixedly connected to one side of the mounting block, and an arc-shaped block is threadedly connected to the arc surface of the threaded rod, with the arc-shaped block abutting against the arc-shaped plate.

[0012] The effect achieved by the above components is as follows: when the shelf height needs to be adjusted and the insert rod is pulled out, the arc-shaped block on the threaded rod is rotated to block the arc-shaped plate, preventing the arc-shaped plate from moving forward continuously due to the spring force, which would cause the insert rod to continuously collide and rub against the surface of the mounting bracket, thus extending the service life of the components.

[0013] Preferably, the side walls of the two mounting brackets are provided with support devices, the support devices including four U-shaped brackets, the four U-shaped brackets are grouped in pairs, the two groups of U-shaped brackets are respectively fixedly connected to the side walls of the two mounting brackets, the inner wall of the U-shaped brackets is fixedly connected with a fixing rod, the arc surface of the fixing rod is rotatably connected with a rotating block, the surface of the rotating block is fixedly connected with a support block, a long rod is slidably inserted into the U-shaped bracket, a slot is opened on one side of the rotating block, the long rod is slidably connected to the inner wall of the slot of the rotating block, and a round block is fixedly connected to one end of the long rod.

[0014] The effect achieved by the above components is as follows: by setting up a support device, the stability of the mounting rack is enhanced. When it is necessary to enhance the stability of the mounting rack, the rotating block is rotated to unfold the support block, and the long rod is inserted to fix the position of the rotating block. The support block can contact the ground to form support, thereby sharing the weight of the shelves inside the mounting rack when they support the culture dishes, and preventing the mounting rack from tipping over.

[0015] Preferably, the arc surface of the fixing rod is fitted with two torsion springs, and the two ends of the torsion springs are fixedly connected to the rotating block and the U-shaped frame, respectively.

[0016] The effect achieved by the above components is that when the limit on the rotating block is released, the torque of the torsion spring will cause the rotating block to rotate upward on the arc surface of the fixed rod, thereby automatically retracting the support block upward and reducing its space occupation.

[0017] Preferably, a friction pad is fixedly connected to the lower surface of the support block, and the friction pad is made of silicone rubber.

[0018] The effects achieved by the above components are as follows: the silicone rubber friction pad can further enhance the stability of the mounting bracket. Silicone rubber has good anti-slip and wear resistance. When the friction pad is in contact with the ground, it can increase the friction between the support block and the ground, preventing the support block from sliding or shifting during placement.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, by setting an adjustment device, the spacing between the shelves can be adjusted. By using the combination of mounting blocks, insert rods, round rods and arc plates, the insert rods can be inserted and removed in the insertion holes, which can easily adjust the position of the shelves in the mounting frame, thereby flexibly changing the spacing between the shelves and improving the practicality and flexibility of the device.

[0021] 2. In this utility model, by setting a support device, the stability of the mounting rack is enhanced. When it is necessary to enhance the stability of the mounting rack, the rotating block is rotated to unfold the support block, and the long rod is inserted to fix the position of the rotating block. The support block can contact the ground to form support, thereby sharing the weight of the shelf inside the mounting rack when it supports the culture dish and preventing the mounting rack from tipping over.

[0028] Reference Figures 1-5 As shown, this utility model provides a technical solution: an adjustable partition spacing bacterial culture dish placement rack, including two mounting racks 1, with four shelves 2 slidably connected to the inner walls of the two mounting racks 1. Adjustment devices 3 are provided on both sides of the four shelves 2. By setting the adjustment devices 3, the spacing between the shelves 2 can be adjusted. Using a combination of mounting blocks 302, insert rods 305, round rods 303, and arc-shaped plates 304, the insert rods 305 can be inserted and removed into the insertion holes 301, conveniently adjusting the position of the shelves 2 within the mounting rack 1, thereby flexibly changing the partition spacing and improving the practicality and flexibility of the device. Support devices 4 are provided on the side walls of the two mounting racks 1. By setting the support devices 4, the stability of the mounting rack 1 is enhanced. When it is necessary to enhance the stability of the mounting rack 1, rotating the rotating block 43 causes the support block 44 to unfold, and inserting the long rod 45 fixes the position of the rotating block 43. The support block 44 can contact the ground to form support, thereby sharing the weight of the shelves 2 within the mounting rack 1 when bearing the culture dishes, preventing the mounting rack 1 from tipping over.

[0029] The specific settings and functions of the adjustment device 3 and the support device 4 will be described in detail below.

[0030] Reference Figure 2 and Figure 3As shown in this embodiment: the adjustment device 3 includes eight mounting blocks 302, which are arranged in pairs. Four sets of mounting blocks 302 are fixedly connected to both sides of the four shelves 2. Each of the two mounting brackets 1 has a socket 301 on its opposite side. A rod 305 is slidably inserted into the mounting block 302, and the rod 305 is slidably connected to the inner wall of the socket 301. A round rod 303 is fixedly connected to one side of the mounting block 302. An arc-shaped plate 304 is slidably connected to the arc surface of the round rod 303. One end of the arc-shaped plate 304 is fixedly connected to the arc-shaped plate 304. A stop block 306 is fixedly connected to the end of the round rod 303 away from the mounting block 302. The size of the rod 305 matches the size of the socket 301. Two baffles 310 are fixedly connected to the upper surface of the shelf 2. The stop block 306 prevents the arc-shaped plate 304 and the rod 305 from detaching from the round rod 303, ensuring the structural stability of the adjustment device 3 and ensuring normal adjustment operation. The baffle 310 prevents the petri dish from slipping, improving placement safety. A spring 307 is fitted onto the arc surface of the round rod 303. Both ends of the spring 307 are fixedly connected to the stop block 306 and the arc-shaped plate 304, respectively. When the insertion rod 305 is aligned with the insertion hole 301, the elastic force of the spring 307 will drive the arc-shaped plate 304 forward, thereby automatically inserting the insertion rod 305 into the inner wall of the insertion hole 301, improving the convenience of the device. One side of the mounting block 302 is fixedly connected... A threaded rod 308 is connected, and an arc-shaped block 309 is threaded onto the arc surface of the threaded rod 308. The arc-shaped block 309 abuts against the arc-shaped plate 304. When the height of the shelf 2 needs to be adjusted and the insert rod 305 is pulled out, the arc-shaped block 309 on the threaded rod 308 is rotated to block the arc-shaped plate 304, preventing the arc-shaped plate 304 from moving forward due to the elastic force of the spring 307, which would cause the insert rod 305 to continuously collide and rub against the surface of the mounting bracket 1, thus extending the service life of the components.

[0031] Reference Figure 4 and Figure 5As shown, specifically, the support device 4 includes four U-shaped frames 41, arranged in pairs. The two pairs of U-shaped frames 41 are fixedly connected to the side walls of the two mounting brackets 1. A fixing rod 42 is fixedly connected to the inner wall of each U-shaped frame 41. A rotating block 43 is rotatably connected to the arc surface of the fixing rod 42. A support block 44 is fixedly connected to the surface of the rotating block 43. A long rod 45 is slidably inserted into the U-shaped frame 41. A slot is opened on one side of the rotating block 43, and the long rod 45 is slidably connected to the inner wall of the slot in the rotating block 43. A round block 46 is fixedly connected to one end of the long rod 45. Two torsion springs 47 are sleeved on the arc surface of the fixing rod 42, and the two ends of the torsion springs 47 are respectively connected to… The rotating block 43 and the U-shaped frame 41 are fixedly connected. When the limit on the rotating block 43 is released, the torque of the torsion spring 47 will drive the rotating block 43 to rotate upward on the arc surface of the fixed rod 42. As a result, the support block 44 will automatically retract upward to reduce its space occupation. A friction pad 48 is fixedly connected to the lower surface of the support block 44. The friction pad 48 is made of silicone rubber. The silicone rubber friction pad 48 can further enhance the stability of the mounting frame 1. Silicone rubber has good anti-slip and wear resistance. When the friction pad 48 contacts the ground, it can increase the friction between the support block 44 and the ground to prevent the support block 44 from sliding or shifting during placement.

[0032] Working principle: When it is necessary to adjust the spacing of the shelves 2, pull the arc plate 304 to drive the insertion rod 305 out of the insertion hole 301 of the mounting bracket 1. Then rotate the arc block 309 threaded on the threaded rod 308 until the arc block 309 abuts against the arc plate 304. At this time, the shelf 2 can be moved up and down to adjust its position. After the adjustment is completed, rotate the arc block 309 on the threaded rod 308 in the opposite direction until it no longer blocks the arc plate 304. At this time, the spring 307 restores its deformation and generates elastic force, pushing the arc plate 304 to drive the insertion rod 305 to automatically insert into the corresponding insertion hole 301, thereby fixing the position of the shelf 2. The baffle 310 on the shelf 2 prevents the culture dish from slipping. All components work together to flexibly change the spacing of the partitions by inserting and pulling the insertion rod 305 to meet the placement requirements of different culture dishes.

[0033] When enhanced stability of the mounting bracket 1 is required, the rotating block 43 is manually rotated to overcome the torque of the torsion spring 47, causing the rotating block 43 to rotate around the fixed rod 42, which in turn drives the support block 44 from a horizontal retracted state to an unfolded state perpendicular to the ground. At this time, the slot on the rotating block 43 aligns with the long rod 45 inside the U-shaped frame 41. The long rod 45 is inserted into the slot to limit and fix the rotating block 43. The silicone rubber friction pad 48 on the lower surface of the support block 44 contacts the ground. Utilizing the good anti-slip and wear-resistant properties of silicone rubber, the friction with the ground is increased, distributing the weight of the culture dish on the shelf 2 and preventing the mounting bracket 1 from tipping over. When the support device 4 is not needed, the long rod 45 is pulled out to release the limitation on the rotating block 43. The torsion spring 47 releases its stored elastic potential energy, generating torque to drive the rotating block 43 to automatically rotate upward on the arc surface of the fixed rod 42, causing the support block 44 to automatically retract, reducing the space occupied, and realizing the flexible unfolding and storage of the support device 4 to adapt to the stability requirements of the mounting bracket 1 in different scenarios.
