[0021] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0022] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.
[0023] Embodiment 1: As Figures 1 - 5 shown, the present utility model provides a natural gas pressure detection device as Figure 1 shown. The natural gas pressure detection device of this embodiment includes a top shell 2 and a bottom shell 4. Slots 3 are symmetrically opened at positions near both sides of the top of the top shell 2. Activity grooves 31 are opened at positions near the edges of both sides inside the top shell 2. Clamping blocks 32 are provided on the inner walls of the two activity grooves 31. Two limiting columns 33 are symmetrically and fixedly connected to the outer surfaces of the two clamping blocks 32 on the opposite sides. A spring 34 is provided on the outer surface of the limiting column 33. A pull handle 35 is fixedly connected between the outer surfaces of the two limiting columns 33. Two insertion blocks 41 are symmetrically and fixedly connected to the bottom of the bottom shell 4. An observation window 21 is provided at a position near the middle of the bottom of the top shell 2. A placement groove 22 is opened at a position near the middle of the top of the top shell 2. A rubber pad 23 is provided on the inner wall of the placement groove 22. A pressure gauge 1 is provided on the inner wall of the rubber pad 23. The slot 3 and the activity groove 31 are in a communicating state. The outer surfaces of the limiting columns 33 all movably penetrate through the outer surface of the top shell 2 and extend to the outside. One end of the spring 34 is fixedly connected to the outer surface of the clamping block 32, and the other end of the spring 34 is fixedly connected to the inner wall of one side of the activity groove 31. The insertion block 41 cooperates with the clamping block 32.
[0024] The effect achieved by the entire Embodiment 1 is that when in use, first gently place the pressure gauge 1 in the specially designed placement groove 22 of the top shell 2. The inner wall of this placement groove 22 is covered with a soft rubber pad 23, which can not only effectively relieve the impact on the pressure gauge 1 by the top shell 2 during movement or use, reduce vibration, but also ensure the stability of the pressure gauge 1 without displacement by increasing friction, improving the measurement accuracy. When installing, align the insertion block 41 under the bottom shell 4 with the slot 3 at the top of the top shell 2, and slowly push the insertion block 41 downward into the slot 3. During the insertion process, the inclined surface at the bottom of the insertion block 41 will naturally contact the inclined surface at the top of the latch block 32, pushing the latch block 32 to slightly contract to both sides under the elastic force of the spring 34. This design makes the insertion process smoother and reduces the resistance during installation. As the insertion block 41 is fully inserted, the teeth on it will precisely engage with the teeth on the latch block 32 to form a firm locking structure. Due to the special design of the tooth shape, this locking method is not only convenient for quick docking during initial installation but also can maintain a stable connection state during daily use, not easily loosening or accidentally falling off. When it is necessary to disassemble the bottom shell 4 for maintenance or replacement, the user only needs to gently pull the handle 35 on the top shell 2 outward, which will drive the movable column 33 and the latch block 32 to move outward in the movable groove 31 due to the elastic force of the spring 34, thus releasing the lock on the insertion block 41. At this time, the user can easily separate the bottom shell 4 from the top shell 2 to complete the disassembly process of the shell. The installation and disassembly become simpler and faster, while ensuring the stability and safety during use. This device protects the pressure gauge 1 from the erosion of the external environment through the easily detachable shell, and also extends its service life, thereby ensuring the accuracy and reliability of the measurement data, improving the service life of the pressure gauge 1. The observation window 21 provided on the top shell 2 is for the user to directly and clearly read the data of the pressure gauge 1 without opening the shell, greatly improving the convenience and efficiency of operation.
[0025] Embodiment 2: As Figures 1 - 5 shown, two guiding holes 24 are opened at the top of the top shell 2, and two guiding columns 42 are fixedly connected to the bottom of the bottom shell 4. The positions of the guiding columns 42 correspond to those of the guiding holes 24.
[0026] The effect achieved by the entire Embodiment 2 is that the design of the guiding holes 42 and the guiding holes 24 is to provide a certain guiding effect during the installation process of the top shell 2 and the bottom shell 4, making the installation more convenient and fast.
[0027] Working principle: When in use, first gently place the pressure gauge 1 in the specially designed placement groove 22 of the top shell 2. The rubber pad 23 inside this placement groove 22 can not only effectively relieve the impact on the pressure gauge 1 during the movement or use of the top shell 2, reduce vibration, but also ensure that the pressure gauge 1 is stable and does not shift by increasing friction, improving the measurement accuracy. During installation, align the insertion block 41 under the bottom shell 4 with the slot 3 at the top of the top shell 2, and slowly push the insertion block 41 downward into the slot 3. During the insertion process, the inclined surface at the bottom of the insertion block 41 will naturally contact the inclined surface at the top of the locking block 32, pushing the locking block 32 to slightly contract to both sides under the elastic force of the spring 34. This design makes the insertion process smoother and reduces the resistance during installation. As the insertion block 41 is fully inserted, the teeth on it will accurately engage with the teeth on the locking block 32, forming a firm locking structure. Due to the special shape design of the teeth, this locking method is not only convenient for quick docking during the initial installation but also can maintain a stable connection state during daily use, not prone to loosening or accidental detachment. When it is necessary to disassemble the bottom shell 4 for maintenance or replacement, the user only needs to gently pull the handle 35 on the top shell 2 outward, which will drive the movable column 33 and the locking block 32 to move outward in the movable groove 31 due to the elastic force of the spring 34, thereby releasing the locking of the insertion block 41. At this time, the user can easily separate the bottom shell 4 from the top shell 2 to complete the disassembly process of the shell. The installation and disassembly become simpler and faster, while ensuring the stability and safety during use. This device protects the pressure gauge 1 from the erosion of the external environment through the easily disassembled and assembled shell, and also extends its service life, thus ensuring the accuracy and reliability of the measurement data. Moreover, the design of the guiding holes 42 and 24 is to provide a certain guiding effect during the installation of the top shell 2 and the bottom shell 4, making the installation more convenient and fast.
[0028] The above is only a preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
