Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold culture technology, specifically a novel mold incubator. Background Technology
[0002] In the field of microbial culture, mold incubators are core equipment that provides a stable temperature, humidity, and gas environment for mold growth. Their internal structural design directly affects the culture effect and experimental efficiency.
[0003] Currently, most mainstream mold incubators on the market use fixed or shelf-type internal trays. In actual use, due to the deep and narrow internal space of the chamber, it is very inconvenient to handle the petri dishes, especially when handling them deep in the tray. It is also easy to bump into the surrounding petri dishes, which is not conducive to use and causes many problems. Therefore, based on the above shortcomings, a new type of mold incubator is introduced to improve this. Utility Model Content
[0004] The purpose of this invention is to provide a novel mold incubator to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel mold incubator, comprising a mold incubator, wherein bases are symmetrically installed on both sides of the inner cavity of the mold incubator from top to bottom, and locking holes are symmetrically opened on both the front and rear sides of the inner outer side of the base, a movable seat is embedded in the inner cavity of the base, a locking ball is provided at the center of the outer side of the movable seat, the locking ball and the locking hole are mutually engaged, rollers are installed at both the upper and lower ends of the movable seat, a base is installed on the inner side of the movable seat extending out of the outer wall of the base, a base plate is provided at the bottom inner side of the base, positioning posts are provided on both the front and rear sides of the top of the base plate, a top plate is assembled on the top of the base plate, positioning holes are opened on both the front and rear sides of the outer wall of the top plate, the positioning holes and the positioning posts are mutually engaged, and a tray is provided on the inner side of the top plate.
[0006] Preferably, the ball is made of rubber.
[0007] Preferably, the positioning post and the positioning hole are matched and their positions correspond.
[0008] Preferably, the tray is provided with a handle on the front side.
[0009] Preferably, the distance between two adjacent trays is 30cm.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This novel mold incubator, through the cooperation between the base, the locking hole, the locking ball, and the rollers, can drive the moving seat and all the structural components on the moving seat to move forward or backward together. Through the cooperation between the base, the bottom plate, the positioning column, the top plate, and the positioning hole, the tray can be disassembled and assembled. The device has a simple structure and reasonable design. It adopts a pull-out method, which allows the tray to be moved out for operation when picking up and putting down the culture dishes. This not only avoids space constraints and prevents contact with the surrounding culture dishes, making it convenient to use, but also facilitates the disassembly and assembly of the tray, making subsequent maintenance and repairs easier. It is flexible in use, highly practical, and meets the needs of the current market. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0016] Please see Figure 1-3This utility model provides a technical solution: a novel mold incubator, including a mold incubator 1. Bases 2 are symmetrically installed on both sides of the inner cavity of the mold incubator 1 from top to bottom. Holes 3 are symmetrically opened on both the front and rear sides of the outer side of the inner cavity of the bases 2. A movable seat 4 is embedded in the inner cavity of the base 2. A retaining ball 5 is set at the center of the outer side of the movable seat 4, and the retaining ball 5 is engaged with the retaining hole 3. Rollers 6 are installed at both the upper and lower ends of the movable seat 4. A base 7 is installed on the inner side of the movable seat 4 extending out of the outer wall of the base 2. A base plate 8 is set at the bottom inner side of the base 7. Positioning posts 9 are set on both the front and rear sides of the top of the base plate 8. A top plate 10 is assembled on the top of the base plate 8. Positioning holes 11 are opened on both the front and rear sides of the outer wall of the top plate 10, and the positioning holes 11 are interlocked with the positioning posts 9. A tray 12 is set on the inner side of the top plate 10.
[0017] As a preferred option, the ball 5 is made of rubber and is elastic, allowing it to be deformed by compression.
[0018] As a preferred option, the positioning pin 9 and the positioning hole 11 are matched and their positions correspond.
[0019] As a preferred option, the tray 12 is further provided with a handle on the front side, which facilitates the pulling operation of the tray 12.
[0020] As a preferred option, the distance between two adjacent upper and lower trays 12 is 30cm.
[0021] All electrical components mentioned in this solution are existing technologies, and their models are only one of them. Any electrical component that meets the requirements of this solution can be used.
[0022] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, without further explanation of electrical control. The specific work is as follows.
[0023] In use, open the front door of the mold incubator 1 and pull the corresponding tray 12 forward forcefully. During this process, the tray 12 will move the top plate 10, positioning post 9, bottom plate 8, base 7, rollers 6, retaining ball 5, and moving seat 4 forward together. Due to the characteristics of its material, the retaining ball 5 will be squeezed and deformed and detached from the inner cavity of the rear retaining hole 3 when it moves forward. When the tray 12 is completely removed from the mold incubator 1, the retaining ball 5 will lock into the inner cavity of the front retaining hole 3. The mutual locking between the retaining hole 3 and the retaining ball 5 can fix the position of the tray 12. At this time, the operator can take and put the petri dishes on the tray 12. After the operation is completed, follow the above method to remove the petri dishes. The tray 12 can be moved backward to its reset position. When the tray 12 needs to be disassembled, simply move the tray 12 upward. When the positioning post 9 moves out of the inner cavity of the positioning hole 11, the tray 12 will also be disassembled. During installation, simply align the positioning hole 11 with the positioning post 9, that is, place the top plate 10 on the bottom plate 8 to complete the installation of the tray 12. The device has a simple structure and reasonable design. It adopts a pull-out method, which allows the tray 12 to be moved out for operation when handling culture dishes. This not only avoids space constraints and prevents contact with surrounding culture dishes, making it convenient to use, but also facilitates the disassembly and assembly of the tray 12, making subsequent maintenance and repair easier. It is flexible in use, highly practical, and suitable for widespread application.
