Description

Technical Field

[0001] This utility model relates to the field of pressure control device technology, specifically a multi-stage exhaust pressure control device for an air compressor. Background Technology

[0002] An air compressor, also known as an air compressor, is a device used to compress gas. During the use of an air compressor, it is usually necessary to discharge gas. When discharging gas, a pressure control device is usually required to control and adjust the discharge pressure of the air compressor in multiple stages according to the needs.

[0003] In existing technologies, when controlling and adjusting the multi-stage exhaust pressure of an air compressor, a control switch is typically used. The plastic casing of the control switch is removed by turning a bolt, and the internal screw is turned to adjust the air pressure; clockwise increases the pressure, and counterclockwise decreases it. However, in practice, when adjusting the pressure by turning the screw inside the control switch, operators often rely on feel, which easily leads to excessive or insufficient pressure adjustment, requiring multiple reversals for calibration. This inaccurate screw-turning method makes controlling and adjusting the exhaust pressure inconvenient. Therefore, an improved multi-stage exhaust pressure control device for air compressors is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to provide a multi-stage exhaust pressure control device for air compressors to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-stage exhaust pressure control device for an air compressor, comprising a mounting base, a control switch body disposed on the top of the mounting base, an exhaust valve body disposed on the right side of the mounting base, a pressure gauge disposed on the front of the mounting base, a multi-stage pressure regulating mechanism disposed on the top and outside of the control switch body, and a storage mechanism disposed on the left side of the multi-stage pressure regulating mechanism.

[0006] The multi-stage pressure regulating mechanism includes a precision adjustment component and a protective mounting component, wherein the protective mounting component is disposed outside the precision adjustment component.

[0007] Preferably, the precision adjustment component includes an indicator directional mark disposed on the top of the control switch body. The top of the control switch body is provided with an indicator for adding or subtracting weights. The control switch body has a multi-stage adjustment bolt inside. A contact side post is fixedly installed on the top of the multi-stage adjustment bolt. A slot post is fixedly installed on the top of the contact side post. A limit seat is fixedly installed on the top of the control switch body. A paddle spring is provided inside the limit seat, which facilitates precise adjustment of the exhaust pressure through the precision adjustment component.

[0008] Preferably, the end of the paddle spring away from the limit seat is located on the inner side of the contact side post, and two direction indicators are provided, which are symmetrically distributed on the top of the control switch body to facilitate the user to indicate the adjustment direction.

[0009] Preferably, the protective mounting assembly includes a mounting bolt, which is threaded inside the control switch body, and a protective shell is provided on the outside of the mounting bolt to facilitate protection of the control switch body through the protective mounting assembly.

[0010] Preferably, the control switch body has a threaded groove inside, and the mounting bolt is threaded into the threaded groove inside the control switch body, which facilitates the fixing of the protective shell.

[0011] Preferably, the storage mechanism includes a storage shell, which is fixedly installed on the left side of the protective shell. A sealing cover is slidably installed inside the storage shell, and an auxiliary insertion tool is provided inside the storage shell to facilitate the storage of the auxiliary insertion tool through the storage mechanism.

[0012] Preferably, the sealing cap has a hole at the corresponding position of the auxiliary insertion tool, and the auxiliary insertion tool is slidably installed inside the hole in the sealing cap to facilitate the placement of the auxiliary insertion tool.

[0013] Compared with the prior art, this utility model provides a multi-stage exhaust pressure control device for air compressors, which has the following beneficial effects:

[0014] 1. This multi-stage exhaust pressure control device for air compressors, through its multi-stage pressure adjustment mechanism, is protected by a protective housing. The multi-stage adjustment bolts allow for multi-stage adjustment of the exhaust pressure, which can be adjusted according to requirements and the pressure gauge display. The slotted post drives the rotating contact plate post, which in turn contacts a lever spring. Each rotation of the contact plate post causes the lever spring to make contact with a new contact plate on the contact plate post, producing a crisp sound and adjusting the air pressure by one level. The device allows for precise, quantitative adjustment of the multi-stage adjustment bolts, preventing over- or under-adjustment and improving the convenience of multi-stage exhaust pressure adjustment for air compressors.

[0015] 2. The multi-stage exhaust pressure control device for this air compressor, through its storage mechanism, allows for the storage of auxiliary insertion tools during use via a storage shell and sealing cover. When the tools are not carried, the protective shell can be disassembled and the multi-stage adjusting bolts can be adjusted using the auxiliary insertion tools, thus realizing the function of auxiliary storage of auxiliary insertion tools.

The top of the multi-stage adjustment bolt 213 is fixedly mounted with an abutment plate post 214. The top of the abutment plate post 214 is fixedly mounted with a slot post 215. The top of the control switch body 4 is fixedly mounted with a limit seat 216. The limit seat 216 has a paddle spring 217 inside, which facilitates precise adjustment of the exhaust pressure through the precision adjustment component 21.

[0030] Furthermore, the end of the paddle spring 217 away from the limit seat 216 is located on the inner side of the contact side post 214, and there are two direction indicators 211, which are symmetrically distributed on the top of the control switch body 4, so as to give people instructions on the adjustment direction.
