Abstract
Description
Technical Field
[0001] This utility model relates to the field of experimental equipment technology, specifically to a pressure gauge for a carbon dioxide incubator. Background Technology
[0002] In biological cell detection experiments, laboratories need an incubator that can control carbon dioxide. With the help of a carbon dioxide incubator, scientists can optimize the environment to grow and maintain live samples. A carbon dioxide pressure gauge is an instrument used to measure the pressure of carbon dioxide gas. It usually consists of two parts: a pointer that displays the unit in psi (pounds per square inch) and a pressure gauge head.
[0003] Currently, when using a carbon dioxide pressure gauge, the gauge head needs to be inserted into the incubator and fixed in place. Then, the carbon dioxide output is controlled by tightening the adjustment handle until the required pressure value is reached. However, during use, the lens on the outside of the pressure gauge lacks a protective structure. The lens is exposed to the outside for a long time and is easily scratched by sharp objects. In severe cases, it may even crack, affecting normal use. Utility Model Content
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] The pressure gauge for the carbon dioxide incubator includes:
[0006] The pressure gauge body has a second outer shell fitted on its front side and a first outer shell fitted on its back side. A fixing mechanism is provided on the back side of the second outer shell, and the first and second outer shells are fixedly connected by the fixing mechanism.
[0007] A protective lens is connected to the inside of the second housing.
[0008] In one possible implementation, the fixing mechanism includes five screws circumferentially connected to the back side of the second housing, and five first through holes circumferentially opened inside the first housing. One end of each screw passes through the interior of a first through hole, and a nut is threadedly connected to the end of each screw.
[0009] In one possible implementation, the position of the screw corresponds to the position of the first through hole.
[0010] In one possible implementation, a first protective plate is fitted around the outer side of the five screws, and the inner side of the first protective plate has a third through hole fitted around the outer side of the screws.
[0011] In one possible implementation, four buckles are circumferentially connected to the back side of the first housing, and rubber strips are fitted on the outer sides of the four buckles, with a second protective plate connected to one end of each of the four rubber strips.
[0012] In one possible implementation, the rubber strip has a second through hole that is sleeved on the outside of the buckle.
[0013] In one possible implementation, the four latches are staggered with the five first through holes.
[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0015] 1. The protective lens is fixed inside the second housing. The first housing is placed on the back of the pressure gauge body, and the second housing is placed on the front of the pressure gauge body. The first and second housings are fixed to the front and rear sides of the pressure gauge body by screws and nuts. At the same time, the protective lens is firmly fixed to the front of the pressure gauge body, thus achieving the effect of protecting the lens on the outside of the pressure gauge.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0027] This application provides a pressure gauge for a carbon dioxide incubator, thus addressing the problems in the prior art.
[0028] The technical solution in this application is to solve the above problems, and the overall approach is as follows:
[0029] Example 1:
[0030] The specific structure of this embodiment is as follows: Figures 1-4 As shown, the pressure gauge for the carbon dioxide incubator includes:
[0031] The pressure gauge body 5 has a second outer shell 3 fitted on its front side and a first outer shell 1 fitted on its back side. A fixing mechanism is provided on the back side of the second outer shell 3. The first outer shell 1 and the second outer shell 3 are fixedly connected by the fixing mechanism. The second outer shell 3 is fitted on the front side of the pressure gauge body 5, and the protective lens 4 is aligned with the lens on the outside of the pressure gauge body 5. Then, the first outer shell 1 is fitted on the back side of the pressure gauge body 5, and the screw 9 is inserted into the first through hole 11 inside the first outer shell 1 and extends out. Then, the nut 10 is put on and rotated to fix the position of the protective lens 4. Before the first outer shell 1 is fitted on the back side of the pressure gauge body 5, the third through hole 13 inside the first protective plate 2 is fitted on the outside of the screw 9, which facilitates the installation of the first protective plate 2 and improves the protection effect on the outside of the pressure gauge body 5. Finally, one end of the four rubber strips 7 on the outside of the second protective plate 6 is simultaneously fitted on the outside of the buckle 8, which facilitates the fixing of the second protective plate 6 and improves the protection effect on the back side of the pressure gauge body 5.
[0032] The inner side of the second outer shell 3 is connected to a protective lens 4. By setting the protective lens 4, it is beneficial to protect the lens on the outside of the pressure gauge. The protective lens 4 is made of high-transparency acrylic sheet. Acrylic sheet has good transparency performance and is a material with excellent transparency. It belongs to colorless transparent organic glass sheet. Secondly, it has excellent weather resistance. Even if it is exposed to sunlight, wind and rain for a long time, its performance will not change.
[0033] In some examples, the fixing mechanism includes five screws 9 circumferentially connected to the back side of the second housing 3. The interior of the first housing 1 has five first through holes 11 circumferentially opened. One end of the screw 9 passes through the interior of the first through hole 11, and the end of the screw 9 is threaded with a nut 10. The first housing 1 is fitted onto the back side of the pressure gauge body 5, and the second housing 3 is fitted onto the front side of the pressure gauge body 5. The first housing 1 and the second housing 3 are fixed to the front and rear sides of the pressure gauge body 5 by the screws 9 and nuts 10. At the same time, the protective lens 4 is firmly fixed to the front side of the pressure gauge body 5, thus achieving the effect of protecting the lens on the outside of the pressure gauge.
[0034] In some examples, the position of the screw 9 corresponds to the position of the first through hole 11, which makes it convenient to insert one end of the screw 9 into the first through hole 11, then put on the nut 10 and rotate it, which is beneficial to complete the fixed connection between the first outer shell 1 and the second outer shell 3.
[0035] By adopting the above technical solution:
[0036] The protective lens 4 is fixed inside the second housing 3. The first housing 1 is fitted onto the back of the pressure gauge body 5, and the second housing 3 is fitted onto the front of the pressure gauge body 5. The first housing 1 and the second housing 3 are fixed to the front and rear sides of the pressure gauge body 5 by the screw 9 and the nut 10. At the same time, the protective lens 4 is firmly fixed to the front of the pressure gauge body 5, thus achieving the effect of protecting the lens on the outside of the pressure gauge.
[0037] Example 2:
[0038] The specific structure of this embodiment is as follows: Figures 1-6 As shown, a first protective plate 2 is fitted on the outside of the five screws 9. The first protective plate 2 has a third through hole 13 that fits on the outside of the screws 9. When the first protective plate 2 needs to be installed, first, the second outer shell 3 is fitted on the front side of the pressure gauge body 5, and the third through hole 13 inside the first protective plate 2 is fitted on the outside of the screws 9. Then, the first outer shell 1 is fitted on the back side of the pressure gauge body 5, and the screws 9 are inserted into the first through hole 11 inside the first outer shell 1 and extended out. Then, the nut 10 is put on and rotated, which facilitates the installation of the first protective plate 2. When the first protective plate 2 needs to be removed, the nut 10 is removed first, which makes it easier to remove the first outer shell 1, and then the first protective plate 2 can be removed from the outside of the five screws 9.
[0039] In some examples, four buckles 8 are circumferentially connected to the back side of the first outer shell 1. Each of the four buckles 8 is fitted with a rubber strip 7. One end of each of the four rubber strips 7 is connected to a second protective plate 6. When the second protective plate 6 needs to be installed, one end of each of the four rubber strips 7 on the outside of the second protective plate 6 is simultaneously fitted onto the outside of the buckles 8, which helps to fix the second protective plate 6. When the second protective plate 6 needs to be removed, one end of each of the four rubber strips 7 on the outside of the second protective plate 6 is removed from the outside of the buckles 8 to complete the disassembly.
[0040] In some examples, the rubber strip 7 has a second through hole 12 that is sleeved on the outside of the buckle 8. Sleeving the second through hole 12 at one end of the rubber strip 7 onto the outside of the buckle 8 is beneficial for fixing the second protective plate 6.
[0041] In some examples, the four clips 8 and the five first through holes 11 are staggered. By setting the four clips 8 and the five first through holes 11 to be staggered, it is beneficial to allow the four clips 8 and the five first through holes 11 to be disassembled and assembled separately without interfering with each other.
[0042] By adopting the above technical solution:
[0043] By setting the first protective plate 2 and the second protective plate 6, it is beneficial to protect the pressure gauge body 5 from all sides and the back side.
[0044] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
