[0002] Designing a pressure gauge convenient to maintenance involves multiple technical fields, including but not limited to: mechanical design: the principles of mechanical design need to be considered in designing the shell, connecting pieces, display devices, etc. of the pressure gauge, including structural strength, rigidity, connection methods, etc. Sensor technology: the measurement principle of the pressure gauge is usually carried out by sensors, involving the selection, installation, calibration, maintenance, etc. of pressure sensors. Material science: appropriate materials need to be selected for the shell, sealing elements, etc. of the pressure gauge, considering their mechanical properties, corrosion resistance, wear resistance, etc. This requires knowledge in the field of material science. Connection technology: in order to facilitate maintenance, the connecting pieces of the pressure gauge need to be designed with reasonable threads, plug-in joints, quick-mount structures, etc. This requires knowledge in the field of connection technology. Fault diagnosis and maintenance technology: designing a pressure gauge convenient to maintenance requires considering the methods of fault diagnosis, maintenance steps, selection of maintenance tools and equipment, which requires knowledge in the relevant fault diagnosis and maintenance technology. Therefore, designing a pressure gauge convenient to maintenance requires knowledge in multiple technical fields, including mechanical design, electronic technology, material science, connection technology, and fault diagnosis and maintenance technology, etc.

[0003] However, the traditional pressure gauge needs to be closed to stop the water flow when the entire gauge head is damaged, or another water gate needs to be designed to ensure that the liquid does not flow out when the pressure gauge is disassembled, which not only makes the traditional gauge head difficult to disassemble, but also results in high cost. For repairing the pressure gauge, the traditional pressure gauge is generally welded or crimped by a machine tool, which is relatively difficult to disassemble and inconvenient to maintain. UTILITY MODEL CONTENT

[0004] In order to make up for the above shortcomings, the utility model provides a pressure gauge convenient to maintenance, aiming to improve the problems that the traditional gauge head is difficult to disassemble from the water pipe, the disassembly is relatively time-consuming and troublesome, and the cost is relatively high, and the shell of the gauge head is relatively difficult to disassemble when repairing the gauge head, which is inconvenient to maintain.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: a pressure gauge convenient to maintenance, comprising a water pipe, the upper end of the water pipe is fixedly connected with a switch mechanism, the upper end of the switch mechanism is fixedly connected with a water inlet pipe, the upper end of the water inlet pipe is fixedly connected with a gauge body, a plurality of outer pull strip inclined holes are formed in the both sides of the gauge body, and buckle mechanisms are arranged at the both ends of the gauge body.

[0015] Further, the spring plate conical buckle is slidably connected to the spring ring, and the spring plate conical buckle is slidably connected to the collar.
