Description
Technical Field
[0001] This utility model relates to the field of pressure gauge disassembly and assembly technology, and in particular to the mechanical structure of a pressure gauge movement that facilitates quick disassembly and assembly. Background Technology
[0002] In industrial production, equipment maintenance, and instrument testing, pressure gauges, as core pressure monitoring components, directly determine the accuracy of pressure data through the stable operation of their mechanical structure. In practical applications, pressure gauge movements require regular calibration, maintenance, or component replacement. For example, in chemical pipeline pressure monitoring scenarios, corrosion from the medium can cause wear on the internal transmission components of the movement, or the movement may need to be disassembled for accuracy adjustments during routine equipment maintenance. Furthermore, under certain special operating conditions, it is necessary to replace movement modules with different ranges according to monitoring requirements. The need for maintenance or replacement of pressure gauge movements, coupled with excessively long disassembly and assembly times, can lead to production interruptions or safety risks. Therefore, the demand for rapid disassembly and assembly of pressure gauge movement mechanical structures is becoming increasingly urgent.
[0003] In existing technologies, traditional pressure gauge movements often employ multiple sets of bolts for fixing, welding, or integrated encapsulation structures. Disassembly and assembly require specialized tools to remove fasteners one by one, and locating the assembly position takes a considerable amount of time, severely impacting equipment maintenance efficiency. Excessive disassembly and assembly time can easily cause production interruptions, affecting subsequent production support operations. The quick-disassembly and maintenance capabilities of pressure gauge movements are relatively insufficient, and the convenience of initial installation and subsequent maintenance and replacement is inadequate. Furthermore, the shock absorption and impact protection capabilities of the movement during disassembly and assembly are not good enough. Prolonged vibration can easily cause the clips to loosen or the insertion interface to shift, leading to the dislocation of precision components such as gears and pointer shafts inside the movement, resulting in scattering and potential internal damage. At the same time, the sealing performance of the outer casing is not good enough, and the waterproof and leak-proof capabilities are insufficient, affecting the service life of the equipment. This fails to meet the basic requirements for tightness and protection during disassembly and assembly in practical applications. Therefore, we propose a pressure gauge movement mechanical structure that facilitates quick disassembly and assembly to solve the above problems. Utility Model Content
[0004] In response to the problems raised, this utility model provides a pressure gauge movement mechanical structure that is easy to assemble and disassemble quickly, thereby solving the aforementioned problems.

The outer side of the mounting support rods is fitted with a buffer rubber ring that abuts and is fixed inside the protective back shell. The back of the protective back shell is embedded with a waterproof sealing ring that fits onto the outer tube of the main body of the movement. The connection between the protective back shell and the waterproof outer shell is provided with a sealing waterproof component. The outer side of the waterproof outer shell is evenly hinged with quick-release buckle pieces that snap onto the protective back shell.

[0009] Preferably, the outer side of the buffer rubber ring is uniformly provided with a limiting support groove, and the inside of the protective back shell is uniformly fixedly installed with a limiting protection strip, the side of the limiting protection strip away from the protective back shell being engaged and positioned in the limiting support groove.
[0010] Preferably, the sealing and waterproof component includes a waterproof inner ring and a filling outer ring. The waterproof inner ring has waterproof grooves on both its front and rear sides. The protective back shell and the waterproof outer shell are respectively inserted into and fitted into the two waterproof grooves on opposite sides. The filling outer ring is sleeved on the outside of the waterproof inner ring. The inner two sides of the filling outer ring abut against the protective back shell and the waterproof outer shell, respectively. Multiple quick-release clips abut against the outside of the filling outer ring.
