Description

Technical Field

[0001] This utility model relates to the field of pressure measurement and calibration technology, and in particular to the drainage box inside a portable pressure calibrator. Background Technology

[0002] With the increasing demand for accurate pressure parameter verification in industrial production, equipment maintenance and other scenarios, portable pressure calibrators are widely used due to their ease of mobile operation. The drain box inside the box is a key auxiliary component, mainly used to collect and drain residual liquid generated during the verification process, to prevent liquid accumulation from damaging the internal components of the instrument and to ensure the continuous and stable operation of the calibrator. In existing technologies, the drainage structure inside the portable pressure calibrator box often lacks a flow guiding design, allowing residual liquid to flow freely and be difficult to collect and discharge. Leaked liquid dripping directly onto the plush material at the bottom of the instrument box can cause mold growth, and it cannot be guaranteed that the liquid will drain out through the drain hole. At the same time, the disassembly and assembly of the drainage box often relies on tools, and the steps are cumbersome, which not only prolongs the replacement time, but also affects work efficiency in outdoor and field emergency calibration scenarios due to the inconvenience of disassembly and assembly. Therefore, the proposed drain box inside the portable pressure calibrator box is intended to solve the above problems. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a drain box inside the portable pressure calibrator, aiming to improve the lack of drainage and flow design in the prior art, which makes it easy for residual calibrator liquid to drip and accumulate at will, potentially corroding the internal components of the box; and the replacement of the drain box requires complicated operation, which is not only time-consuming and labor-intensive, but also results in poor ease of use and equipment practicality.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A portable pressure calibrator includes a calibrator body with a slide rail fixedly connected inside. A drain box body is slidably connected inside the calibrator body, and a sliding strip is fixedly connected to the bottom of the drain box body. A first bakelite board and a second bakelite board are fixedly connected inside the calibrator body. A drain outlet is provided between the first bakelite board and the second bakelite board. A quick-release assembly is provided between the calibrator body and the drain box body. As a further description of the above technical solution: The quick-release assembly includes a fixing block one and a protective shell. The fixing block one is fixedly connected to the outside of the main body of the calibrator box, and the protective shell is fixedly connected to the inside of the main body of the calibrator box. A rotating shaft is rotatably connected inside the fixing block one. A fixing block two is fixedly connected to one end of the rotating shaft. A fixing ring is fixedly connected to the outside of the rotating shaft. A lever is fixedly connected to the outside of the fixing ring. A support rod is fixedly connected to the outside of the fixing ring. A pin is fixedly connected to the end of the support rod away from the fixing ring. A spring is sleeved on the outside of the pin. A baffle is fixedly connected to the outside of the pin. As a further description of the above technical solution: A handle is fixedly connected to the outside of the main body of the drainage box, and both the first and second plywood boards are fixedly connected at an angle inside the main body of the calibrator box. As a further description of the above technical solution: A drain pipe is fixedly connected to the bottom of the main body of the calibration instrument box; As a further description of the above technical solution: The sliding bar is slidably connected to the outside of the slide rail; As a further description of the above technical solution: One end of the spring is fixedly connected to one side of the baffle, and the other end of the spring abuts against the inner wall of the protective shell; As a further description of the above technical solution: The baffle is slidably connected inside the protective shell, and the pin is slidably connected inside the protective shell; As a further description of the above technical solution: The main body of the drainage box has a groove on its outer side, and one end of the pin is inserted into the groove.

[0005] This utility model has the following beneficial effects: 1. In this utility model, when the liquid inside the pressure calibrator needs to be discharged, the residual liquid from the calibration naturally drips down and flows to the inclined slope of the first and second plywood boards. The liquid slides along the surface and converges at the drain outlet at the junction. Then, it flows into the main body of the drain box through the drain outlet and is discharged outside the box through the drain pipe at the bottom of the calibrator box, reducing the risk of corrosion of the internal components by the liquid and ensuring the stable operation of the equipment.

[0006] 2. In this utility model, when it is necessary to replace the main body of the drainage box, first press the lever outside the main body of the calibrator box. The lever rotates in the fixed block through the rotating shaft, which drives the fixed ring and the support rod to rotate synchronously. The pin drives the baffle to compress the spring until the pin is completely disengaged from the groove, which can release the lock on the main body of the drainage box. No tools are required for disassembly, which greatly improves the replacement efficiency. Attached Figure Description

Detailed Implementation

[0009] 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.

[0010] Reference Figures 1-5 An embodiment of this utility model provides a drain box inside a portable pressure calibrator, comprising a calibrator body 1, a slide rail 16 fixedly connected inside the calibrator body 1, a drain box body 3 slidably connected inside the calibrator body 1, a sliding strip 15 fixedly connected to the bottom of the drain box body 3, a bakelite board 12 fixedly connected inside the calibrator body 1, a bakelite board 23 fixedly connected inside the calibrator body 1, a drain outlet 11 between bakelite board 12 and bakelite board 23, a quick-release assembly between the calibrator body 1 and the drain box body 3, a handle 2 fixedly connected to the outside of the drain box body 3, bakelite board 12 and bakelite board 23 both being inclinedly fixedly connected inside the calibrator body 1, a drain pipe 4 fixedly connected to the bottom of the calibrator body 1, and the sliding strip 15 slidably connected to the outside of the slide rail 16.

[0011] The calibrator housing body 1 serves as the mounting base for the entire component. The handle 2 is used to pull the drain box body 3 out of the housing and push it in for installation. The drain box body 3 is the core carrier for liquid collection. The drain pipe 4 is used to directly discharge the liquid collected at the drain port 11 to the outside of the calibrator housing body 1, preventing liquid accumulation inside the housing and ensuring a clean and tidy interior. Phenolic reticulum board 12 and Phenolic reticulum board 2 13 work together to guide the liquid to the drain port 11. The drain port 11 is the endpoint of the flow guided by Phenolic reticulum board 12 and Phenolic reticulum board 2 13, concentrating all the liquid inside the housing into the drain pipe 4 to prevent dispersion and leakage. The sliding strip 15 provides a stable sliding path for pulling out the drain box body 3, restricting the direction of movement of the drain box body 3 and preventing offset during insertion and removal. The slide rail 16 ensures that the drain box body 3 is always inserted and removed in a straight line, preventing misalignment of the quick-release components due to offset.

[0012] Reference Figures 1-5 The quick-release assembly includes a fixing block 9 and a protective shell 18. The fixing block 9 is fixedly connected to the outside of the calibrator box body 1, and the protective shell 18 is fixedly connected to the inside of the calibrator box body 1. A rotating shaft 10 is rotatably connected inside the fixing block 9. A fixing block 14 is fixedly connected to one end of the rotating shaft 10. A fixing ring 8 is fixedly connected to the outside of the rotating shaft 10. A lever 7 is fixedly connected to the outside of the fixing ring 8. A support rod 6 is fixedly connected to the outside of the fixing ring 8. A pin 5 is fixedly connected to the end of the support rod 6 away from the fixing ring 8. A spring 20 is sleeved on the outside of the pin 5. A baffle 19 is fixedly connected to the outside of the pin 5. One end of the spring 20 is fixedly connected to one side of the baffle 19, and the other end of the spring 20 abuts against the inner wall of the protective shell 18. The baffle 19 is slidably connected inside the protective shell 18. The pin 5 is slidably connected inside the protective shell 18. A groove 17 is opened on the outside of the drain box body 3, and one end of the pin 5 is inserted into the groove 17.

[0013] Fixed block 19 serves as a fixed support for rotating shaft 10. Rotating shaft 10 converts the pressing action of lever 7 into the extension and retraction action of pin 5 through its own rotation, realizing the power transmission for locking and unlocking. Fixed block 214 serves as an anti-disengagement limit block for rotating shaft 10. Protective shell 18 provides a precise sliding path for pin 5, ensuring that pin 5 always extends and retracts in a straight line, accurately aligning with the groove 17 of drain box body 3. Fixed ring 8 converts the rotational motion of rotating shaft 10 into radial force: when lever 7 is pressed, fixed ring 8 drives support rod 6 to rotate around rotating shaft 10, thereby pulling pin 5 to retract; lever 7 is used to drive pin 5 to retract for unlocking or locking when pressed, and support rod 6 is used to hold fixed ring 8 in place. The rotational motion of the fixed ring 8 is converted into the linear motion of the pin 5. When the fixed ring 8 rotates, the support rod 6 drives the pin 5 to slide inside the protective shell 18 through the push-pull action. The pin 5 is used to push the drain box body 3 into the installation position. The pin 5 is inserted into the groove 17 under the tightening force of the spring 20. The mechanical insertion achieves the rigid locking of the drain box body 3. The groove 17 is used as a positioning slot for the pin 5 to ensure that there is no loose gap after the pin 5 is inserted. The spring 20 is in a slightly compressed state in its natural state to provide a continuous tightening force for the pin 5, ensuring that the pin 5 will not come out due to vibration after being inserted into the groove 17, thus improving the locking stability. The baffle 19 is used to ensure that the pin 5 can slide smoothly inside the protective shell 18.

[0014] Working principle: When the liquid inside the pressure calibrator needs to be drained, the residual calibrating liquid will drip naturally. Under the influence of gravity, the liquid will flow onto the bakelite board 12 and bakelite board 23. Since bakelite board 12 and bakelite board 23 are inclined, the liquid will slide along the surface and eventually converge and flow into the drain outlet 11 at the junction of the two. Then, the liquid flows into the drain box body 3 through the drain outlet 11 and is directly discharged outside the box through the drain pipe 4 at the bottom of the calibrator box body 1, avoiding the accumulation of liquid inside the drain box body 3. When it is necessary to replace the main body 3 of the drain box, first press the lever 7 on the outside of the main body 1 of the calibrator box. Then, the lever 7 rotates inside the fixed block 9 via the rotating shaft 10, thereby driving the fixed ring 8 and the support rod 6 to rotate synchronously. Subsequently, the support rod 6 pulls the pin 5 to retract into the protective shell 18. Then, the pin 5 drives the baffle 19 to compress the spring 20 until the pin 5 is completely disengaged from the groove 17, thereby releasing the lock on the main body 3 of the drain box. Then, by smoothly sliding the handle 2 along the sliding bar 15 and the slide rail 16, the main body 3 of the drain box can be pulled out from the main body 1 of the calibrator box. When replacing the new drain box body 3, first push the new drain box body 3 into the calibrator box body 1 along the sliding bar 15 and the slide rail 16. Then press the lever 7 to pull the support rod 6 to retract the pin 5 into the protective shell 18. This causes the pin 5 to drive the baffle 19 to compress the spring 20. At the same time, the pin 5 will retract into the fixing ring 8. Then rotate the lever 7, and the spring 20 will rebound, causing the pin 5 to extend out along the inside of the protective shell 18. This allows one end of the pin 5 to be inserted into the groove 17 on the outside of the drain box body 3. Then fix it in place, thus completing the replacement of the drain box body 3.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
