Description

Technical Field

[0001] This utility model relates to the field of pressure calibrators, and in particular to a pressure calibrator that is easy to disassemble. Background Technology

[0002] A pressure calibrator is a specialized pressure calibration instrument for calibrating various pressure transmitters, pressure sensors, pressure switches, differential pressure transmitters, and digital pressure gauges.

[0003] Existing pressure calibrators, such as the utility model patent with patent application number CN202022823943.8 entitled "A Pressure Calibrator," disclose a pressure calibrator, relating to the technical field of pressure calibrators. It includes a main body shell, a disassembly mechanism, and a shock-absorbing mechanism. The main body shell has a ventilation plate on its side with ventilation holes on its surface. The front of the main body shell has a control panel with a display screen, wiring ports, and control buttons. The top of the main body shell has a disassembly plate with a gasket at its bottom. The bottom of the main body shell has a shock-absorbing support column with anti-slip feet fixedly connected to its bottom. This utility model, when maintenance is required, uses the extension of a locking hydraulic rod to rotate a locking rotating component, causing one end of the locking rotating component to disengage from the locking groove. Once one end of the locking rotating component is out of the locking groove, the disassembly plate can be easily removed. This process is convenient and solves the problem of existing pressure calibrators being inconvenient to disassemble and maintain.

[0004] The aforementioned device uses the extension of a hydraulic rod to disassemble the disassembly plate. Although it achieves the positioning and release of the disassembly plate, the limiting plate remains in place after the restriction on the disassembly plate is released, requiring manual removal of the limiting plate, which is inconvenient.

[0005] Therefore, a pressure calibrator that is easy to disassemble is provided to solve the problems mentioned above. Utility Model Content

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] In the description of this utility model, it should be understood that the terms upper, lower, front, back, left, right, top, bottom, inside, outside, etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0030] Example 1:

[0031] Reference Figure 1-5 A pressure calibrator that is easy to disassemble includes a body 1, and also includes:

[0032] The placement slot 101 is set on the instrument body 1, and the placement slot 101 is provided with four slots 102;

[0033] Inspection plate 104, located within placement slot 101, has four sets of insertion rods 105, which match slots 102. Each insertion rod 105 has a limiting port 106. Piston cylinder 1 201 is fixedly connected within placement slot 101, and is located on the same plane as the insertion rods 105. Two sets of piston cylinders 202 are symmetrically fixedly connected to the sides of placement slot 101, with their extension / retraction ends matching the limiting ports 106. Air pipe 20... 3. Fixedly connected to piston cylinder 1 201, and the other end of air pipe 203 is connected to piston cylinder 202; vent valve 4, fixedly connected to instrument body 1, vent valve 4 is connected to air pipe 203, return spring 301 is sleeved on the telescopic end of piston cylinder 1 201, return spring 301 is connected to the fixed end of piston cylinder 1 201, return spring 302 is sleeved on the telescopic end of piston cylinder 202, return spring 302 is connected to the fixed end of piston cylinder 202.

[0034] When using the instrument, if the user needs to remove the inspection plate 104 on the instrument body 1, simply open the vent valve 4. Since the piston cylinder 202 is initially in the extended state, its telescopic end is stuck in the limit port 106. At this time, under the combined action of the air pressure change and the return spring 302, the telescopic end of the piston cylinder 202 will retract. At this time, the insertion rod 105 will no longer be restricted. At the same time, due to the air pressure change and the insertion rod 105 is no longer restricted, the piston cylinder 201 will extend under the action of the return spring 301, lifting the inspection plate 104 on the insertion rod 105, making it easy for the user to remove the inspection plate 104 for subsequent use.

[0035] When the user needs to install the inspection plate 104, simply close the vent valve 4, align the insertion rod 105 with the slot 102, and insert it. Due to the weight of the inspection plate 104 itself and the downward pressure from the user, the insertion rod 105 will first squeeze the piston cylinder 201, causing the gas in the piston cylinder 201 to enter the piston cylinder 202 through the air pipe 203. At this time, the piston cylinder 202 will extend until it enters the limiting port 106 on the insertion rod 105, thus restricting the insertion rod 105 and completing the installation of the inspection plate 104.

[0036] The instrument 1 mentioned in this embodiment is the SPMK2002 intelligent digital pressure calibrator, which is commonly found on the market.

[0037] Example 2:

[0038] Reference Figure 1-3 A pressure calibrator that is easy to disassemble is basically the same as that in Embodiment 1, but further: an inflatable airbag 103 is fixedly connected in the placement groove 101, the inflatable airbag 103 is connected to the air tube 203, and the inflatable airbag 103 is fixedly connected in a ring shape in the placement groove 101.

[0039] The inflatable airbag 103 can fill the gap between the inspection plate 104 and the placement groove 101, increasing the sealing performance and preventing the entry of external dust and debris.

[0040] Example 3:

[0041] Reference Figure 1-5 A pressure calibrator that is easy to disassemble is basically the same as that in Embodiment 1, but further: multiple sets of rollers 107 are rotatably connected inside the limiting port 106.

[0042] The roller 107 facilitates the sliding of the extension end of the piston cylinder 202 out of the limiting port 106, reducing resistance and friction.

[0043] This utility model, through the configuration of piston cylinder 201, piston cylinder 202, and vent valve 4, enables the quick disassembly of the inspection plate 104. At the same time, the inspection plate 104 will automatically pop out, making it easy to remove and install, which is also convenient and conducive to its promotion.

[0044] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
