Description

Technical Field

[0001] This application relates to a novel airbag pump, belonging to the field of airbag pump technology. Background Technology

[0002] A pneumatic air pump is a device that generates airflow by utilizing the principles of air expansion and compression. Powered by compressed air, the pump chamber is divided into two working chambers by two pneumatic air bags. The alternating suction and discharge of the liquid phase chambers enables liquid transport. When the pneumatic air bags are compressed, air is expelled; when the pressure is released, the air bags expand and draw in new air through a valve, thus generating airflow and providing effective suction. Pneumatic air pumps are widely used in various fields due to their simple structure, low cost, and lack of lubricant requirements.

[0003] However, since airbag pumps use gas as a power source, they will inevitably generate noise. Current technology usually involves wrapping the airbag pump with a large area of ​​sound-absorbing cotton, which is ineffective in reducing noise and is time-consuming and labor-intensive. In addition, airbag pumps inevitably vibrate during operation. To avoid this vibration, bolts are usually used to fix the airbag pump. However, the installation and removal of bolts are very cumbersome, time-consuming and labor-intensive. Utility Model Content

[0051] The gas phase working chamber 142 is provided with an air inlet 15 and an air outlet 16 at its end. A silencer mechanism is installed at the air outlet 16, and the mounting base 10 of the silencer mechanism is connected to the air outlet 16 by a thread.

[0052] In one embodiment, the fixing component 3 includes a first fixing component and a second fixing component. The first fixing component is located below the airbag pump body 1, and the second fixing component is located on the fixing base 2. The first fixing component and the second fixing component are snapped together.

[0053] Specifically, this application connects the airbag pump body 1 and the fixed base 2 by setting a first fixing component and a second fixing component to make the installation and disassembly of the airbag pump body 1 more convenient and quick, and facilitates subsequent inspection and maintenance.

[0054] Specifically, this application does not impose a specific limit on the number of the first fixing component and the second fixing component, and those skilled in the art can select according to the actual situation.

[0055] In one embodiment, the first fixing component includes a first housing 17, which is disposed around the lower part of the airbag pump body 1; a slide rod 18 is provided inside the first housing 17, and a fixing plate 19 is slidably connected to the slide rod 18; a first pull block 20 is fixedly installed on the front side of the fixing plate 19; a plurality of insertion holes 21 are provided on the left and right sides of the fixing plate 19; a first spring 22 is provided on the top of the fixing plate 19; a through hole is provided at the bottom of the first housing 17, and the fixing plate 19 extends through the through hole to the bottom of the first housing 17.

[0057] Specifically, this application does not impose specific limitations on the connection method between the first fixing member and the airbag pump body 1, and those skilled in the art can make the selection according to the actual situation.

[0058] In one specific implementation, the first fixing component is fixedly connected to the airbag pump body 1, and the second fixing component is fixedly connected to the fixing base 2.

[0059] In one embodiment, the second fixing component includes a second housing 23, inside which is provided a sliding rod 24. Sliding plates 25 are slidably connected to both the left and right sides of the sliding rod 24. A second spring 26 is provided on the inner side of the sliding plate 25. A second pull block 27 is provided on the front side of the sliding plate 25. An insertion block 28 corresponding to the insertion hole 21 is provided on the inner side of the sliding plate 25.

[0060] Specifically, this application does not impose specific limitations on the size of the second box 23 or the connection method between the second box 23 and the fixed base 2. Those skilled in the art can make choices according to the actual situation.

[0061] Specifically, this application does not impose a specific limit on the number of insert blocks 28, and those skilled in the art can choose according to the actual situation.

[0062] Specifically, when it is necessary to disassemble the airbag pump body 1 and the fixed base 2, during disassembly, the second pull block 27 is pulled outward, causing the sliding plate 25 to move outward. The second spring 26 deforms, and the sliding plate 25 causes the insert block 28 to move out of the insertion hole 21, releasing the restriction on the fixed plate 19. The first pull block 20 is pulled upward, causing it to move into the inner cavity of the first housing 17. The first spring 22 is compressed and deformed due to the movement of the fixed plate 19, causing the fixed plate 19 to move and releasing the restriction on the fixed plate 19, thereby allowing the airbag pump to be disassembled. The main body 1 is detached from the fixed base 2. When it is necessary to install the airbag pump main body 1 on the fixed base 2, the first pull block 20 is released, the first spring 22 loses its force and deforms, and pushes the fixed plate 19 to move downward. The fixed plate 19 enters the inner side of the second box 23. The second pull block 27 is released, the second spring 26 loses its force and deforms, and drives the sliding plate 25 to move inward. Due to the movement of the sliding plate 25, the insert block 28 is inserted into the insert hole 21, which limits the fixed plate 19, thereby realizing the installation of the airbag pump main body 1 and the fixed base 2.

[0063] In one embodiment, a first movable groove 29 is provided on the front side of the first box 17, and a first pull block 20 passes through the first movable groove 29 and extends to the front side of the first box 17; a second movable groove 30 is provided on the front side of the second box 23, and a second pull block 27 passes through the second movable groove 30 and extends to the front side of the second box 23.

[0064] Specifically, by setting the first moving groove 29 and the second moving groove 30, the moving directions of the first pull block 20 and the second pull block 27 are limited respectively, so as to avoid them from deviating during the movement, which would cause the insert block 28 to not correspond with the fixing plate 19 and thus make installation impossible.

[0065] In one embodiment, the inner side of the second housing 23 is provided with a slot, and the plug 28 passes through the slot and is inserted into the socket 21.

[0066] Specifically, the slot is designed so that the plug 28 can pass through the slot and be inserted into the socket 21. The slot, the plug 28, and the socket 21 are all corresponding in position and shape.

[0067] The various embodiments in this specification are described in a progressive manner. Similar or identical parts between embodiments can be referred to interchangeably. Each embodiment focuses on describing the differences from other embodiments. In particular, the system embodiments are basically similar to the method embodiments, so the description is relatively simple; relevant parts can be referred to the descriptions in the method embodiments.

[0068] The above description is merely an embodiment of this application and is not intended to limit the scope of this application.
