Description

Technical Field

[0001] The utility model relates to the technical field of air pump pressure switches, in particular to a safety air pump pressure switch. Background Art

[0002] In industrial control systems, air pump pressure switches are often used to regulate and maintain the pressure level of fluid, gas or liquid systems. By accurately controlling the pressure, this switch ensures the stability of the system and improves the efficiency and safety of industrial production. Therefore, air pump pressure switches play a vital role in automation control and industrial applications.

[0003] At present, mainstream air pump pressure switches generally adopt a single-layer shell structure, and this design has some potential safety hazards. The single-layer shell structure is easily affected by excessive pressure and impact during use, which may cause shell damage, and then cause system failure or leakage risks. In the case of excessive use, due to the limitation of the single-layer shell, the pressure switch has relatively poor pressure and impact resistance, making it difficult to cope with extreme conditions under high pressure or harsh working environments. In order to solve this problem, we propose a safe air pump pressure switch design. Utility Model Content

[0004] In order to improve the above-mentioned problems, the utility model provides a safety air pump pressure switch.

[0005] The utility model provides a safety air pump pressure switch, which adopts the following technical scheme: a safety air pump pressure switch, comprising a connecting base and a push regulator, the push regulator is connected to the top of the connecting base, the connecting base comprises a metal cylinder, a retaining groove is provided inside the metal cylinder, a connecting spiral tube is installed at the bottom of the metal cylinder, and an air pressure regulating tube is also provided between the metal cylinder and the connecting spiral tube;

[0006] The push regulator comprises a metal push key, and a metal baffle is connected to the bottom of the metal push key.

[0007] Based on the above technical features: This solution can connect and fix the metal cylinder to the connecting screw head of the air pump pressure relief through the connecting screw tube installed at the bottom of the metal cylinder, and through the retaining groove opened inside the metal cylinder and the metal baffle plate installed at the bottom of the metal push key. Because the metal baffle plate matches the retaining groove structure and there is a transition fit between the metal baffle plate and the retaining groove, the metal push key can also be air-tightly connected to the inside of the metal cylinder. The metal baffle ring and the first compression spring installed at the bottom of the metal baffle plate can play a role of elastic support for the bottom of the metal push key air-tightly connected to the inside of the metal cylinder, which can provide a pressure relief for the metal cylinder. The metal push button for internal pressure adjustment plays the role of automatic reset. The metal cylinder designed in this scheme is composed of a protective outer shell and a protective liner. A buffer cavity is also opened between the protective outer shell and the protective liner, which can form a multi-level protection mechanism for the air pump pressure switch. Through the above structural design, not only can the pressure resistance of the air pump pressure switch during use be effectively improved, but also the impact of external impact on its structure can be effectively reduced, thereby enhancing the durability and safety of the air pump pressure switch. This design feature enables the air pump pressure switch to operate more stably and reliably under high-pressure working environment;

[0008] The air pump pressure switch designed in this scheme has a simple and ingenious structure. It mainly realizes a firm connection with the air pump through the connecting screw at the bottom of the metal cylinder. When air pressure is generated inside the air pump, the metal cylinder can be tightly fixed on the connecting screw head of the air pump pressure relief through the connecting screw. In this state, the valve core of the airtight connection in the air pressure regulating pipe groove will be pushed upward by the air pressure, effectively preventing the possibility of air pressure leaking out from the valve core and the air pressure regulating pipe. When the air pressure inside the air pump needs to be released, the user can press the metal pressing key inside the metal cylinder, and the top pressure column at the bottom acts on the valve core to push it downward. This action creates a large gap, so that the air pressure inside the air pump can be quickly released. At this time, the metal pressing key can be effectively reset by cooperating with the first compression spring, the second compression spring and other structures to restore the position of the valve core and the metal pressing key to the original state, thereby avoiding the continuous release of the air pressure inside the air pump. The whole design is ingenious and practical, so that the air pump pressure switch can accurately control the release of the air pressure inside the air pump when needed, thereby improving the safety and controllability of the system.

[0009] As a safety air pump pressure switch described in the utility model, wherein: the metal baffle plate matches the baffle groove structure, and there is a transition fit between the metal baffle plate and the baffle groove.

[0010] Based on the above technical features: First, the matching of the metal baffle and the baffle groove structure ensures that the two can be tightly connected and work together during the operation of the air pump pressure switch. This structural matching not only enhances the stability of the metal baffle in the baffle groove, but also effectively prevents dust, moisture or other impurities from the external environment from entering the baffle groove, thereby protecting key internal components, such as metal push buttons and air pressure regulating tubes, and avoiding possible damage or failure. Secondly, there is a transition fit between the metal baffle and the baffle groove, which means that there is a certain moderate gap on their contact interface. The design of this transition fit takes into account factors such as the thermal expansion and contraction of metal materials, ensuring that under different temperature conditions, the connection between the metal baffle and the baffle groove still maintains relative freedom, thereby avoiding unnecessary stress and deformation caused by temperature changes.

[0011] As a safety air pump pressure switch described in the utility model, wherein: a metal baffle ring is further arranged at the bottom of the metal baffle plate, and a plurality of groups of first compression springs are further connected between the metal baffle plate and the metal baffle ring.

[0012] Based on the above technical features: This solution can play the role of elastic support for the bottom of the metal push key which is airtightly connected to the inside of the metal cylinder by adding a metal baffle ring and a first compression spring at the bottom of the metal baffle plate, and can automatically reset the metal push key which is pressed and adjusted inside the metal cylinder.

[0013] As a safety air pump pressure switch described in the utility model, the metal cylinder includes a protective outer shell, a protective inner shell is arranged inside the protective outer shell, and a buffer cavity is formed between the protective outer shell and the protective inner shell.

[0014] Based on the above technical features: the metal cylinder designed in this scheme is composed of a protective outer shell and a protective inner liner, and a buffer cavity is also opened between the protective outer shell and the protective inner liner, which can constitute a multi-level protection mechanism for the air pump pressure switch. Through the above structural design, not only can the pressure resistance of the air pump pressure switch during use be effectively improved, but also the impact of external impact on its structure can be effectively reduced, thereby enhancing the durability and safety of the air pump pressure switch. This design feature enables the air pump pressure switch to operate more stably and reliably under high-pressure working environment.

[0015] As a safety air pump pressure switch described in the utility model, wherein: a valve core is air-tightly connected in the through groove of the air pressure regulating tube, a storage regulating groove is opened around the air pressure regulating tube, a gear lever is connected between the storage regulating groove and the valve core, the gear lever matches the storage regulating groove structure, and a second compression spring is also sleeved on the outer side of the gear lever.

[0016] Based on the above technical features: This solution can automatically reset the valve core that is pressed downward by means of a gear lever connected between the storage adjustment groove and the valve core, and a second compression spring sleeved on the outside of the gear lever.

[0017] As a safety air pump pressure switch described in the utility model, wherein: the middle part of one end of the metal push button close to the metal baffle is connected with a top pressure column, the top pressure column matches the through groove structure of the air pressure regulating tube, and the top pressure column and the air pressure regulating tube are plug-fitted.

[0018] Based on the above technical features: This solution can push the valve core downward by installing a pressure column in the middle of one end of the metal push key.

[0019] In summary, the present invention has at least one of the following beneficial effects:

[0020] 1. This solution can connect and fix the metal cylinder to the connecting screw head of the air pump pressure relief through the connecting screw tube installed at the bottom of the metal cylinder. Through the retaining groove opened inside the metal cylinder and the metal retaining plate installed at the bottom of the metal push key, the metal retaining plate and the retaining groove structure match, and there is a transition fit between the metal retaining plate and the retaining groove, the metal push key can also be air-tightly connected to the inside of the metal cylinder. Through the metal retaining ring and the first compression spring installed at the bottom of the metal retaining plate, the bottom of the metal push key air-tightly connected to the inside of the metal cylinder can be elastically supported, which can support the metal push key inside the metal cylinder. The adjustable metal push button plays the role of automatic reset. The metal cylinder designed in this scheme is composed of a protective outer shell and a protective liner. A buffer cavity is also provided between the protective outer shell and the protective liner, which can form a multi-level protection mechanism for the air pump pressure switch. Through the above structural design, not only can the pressure resistance of the air pump pressure switch during use be effectively improved, but also the impact of external impact on its structure can be effectively mitigated, thereby enhancing the durability and safety of the air pump pressure switch. This design feature enables the air pump pressure switch to operate more stably and reliably under high-pressure working environment;

[0021] 2. The air pump pressure switch designed in this scheme has a simple and ingenious structure. It is mainly connected to the air pump firmly through the connecting screw at the bottom of the metal cylinder. When air pressure is generated inside the air pump, the metal cylinder can be tightly fixed on the connecting screw head of the air pump pressure relief through the connecting screw.
