Wind pressure switch

Abstract

The invention belongs to the technical field of wind pressure switches, and particularly relates to a wind pressure switch which comprises a mounting base, a wind pressure switch body, a base side cover and a heat preservation cover. The wind pressure switch body is movably mounted on the upper surface of the mounting base, and the heat preservation cover is rotatably connected with one end of the upper surface of the mounting base. According to the wind pressure switch, through the arrangement of a quick release device, when the wind pressure switch body needs to be installed and only a quick release handle needs to be pulled up, a quick release clamping hand can be pulled by the quick release handle to be folded, at the moment, the wind pressure switch body is placed into an installation base, and when the quick release handle is closed, the quick release clamping hand can extend out under the action of a first spring, and the wind pressure switch is clamped; when the wind pressure switch body needs to be dismounted, the wind pressure switch body can be pulled out only by pulling up the quick dismounting handle, so that the quick mounting and dismounting of the wind pressure switch body are achieved, and the problem that an existing wind pressure switch is inconvenient to mount and dismount is effectively solved.

Description

technical field [0001] The invention relates to the technical field of air pressure switches, in particular to an air pressure switch. Background technique [0002] The wind pressure switch is a detection element, which is installed on the equipment that controls the wind pressure, and the micro switch is pushed by the static pressure of the gas, so as to realize the control equipment circuit or pipeline on-off. The wind pressure switch is mainly installed on the equipment. Although the existing installation structure can realize the installation of the air pressure switch, there are also the following problems: the assembly workload is large, and screwing operations need to be performed many times, the air pressure switch is inconvenient to disassemble, and the disassembly life is short. Tapping holes are easy to damage, resulting in unstable connection and reduced disassembly life; affecting the life of the air pressure switch. In addition, because the air pressure switc...

Problems solved by technology

Although the existing installation structure can realize the installation of the air pressure switch, there are also the following problems: the assembly workload is large, and screwing operations need to be performed many times, the air pressure switch is inconvenient to disassemble, and the disassembly life is short. Tapping holes are easy to damage, resulting in unstable connection and reduced life of disassembly and assembly; affecting the life of the air pressure switch

In addition, because the air pressure switch is usually used in an environment where the temperature alternates, the inside of the air pressure switch is a closed space. If air is added to the product, water will be generated inside the product due to the temperature difference. If the air pressure switch The presence of water inside will affect the use effect of the product, and the existing installation structure lacks the function of constant temperature
