DETAILED DESCRIPTION

[0023] The utility model discloses a kind of wind bag pumps with laser displacement device 3 and sensor, such as Figure 1 And Figure 2 Combination, as shown, including wind bag pump main body 1 with connecting rod 12, the shell 11 of the upper and lower ends of the wind bag pump main body 1 is all through connecting with connecting rod 12, the connecting rod 12 is made of the movable connection of two rod bodies 121, the connecting rod 12 is cooperated with the limiting structure 2 that the shell 11 is abutted when connecting rod 12 moves, the wall surface of the through portion of the shell 11 by connecting rod 12 is fixedly connected with first fixed seat 14, the upper of first fixed seat 14 is fixedly connected with laser displacement device 3, the left and right sides of the shell 11 are all equipped with the connecting plate 13 of connecting rod 12 end, the shell 11 of the outer side of connecting plate 13 is equipped with connecting seat 15, the connecting seat 15 is connected with the proximity sensor 4 in the shell 11 of the outer side of connecting plate 13.

[0024] It should be noted that: since the connecting rods 12 at the upper and lower ends of the airbag pump body 1 are connected to the corrugated pipes on the left and right sides of the airbag pump body 1 through the connecting plate 13, forming a structure in which the corrugated pipes and connecting rods 12 are linked, and since the connecting rod 12 is connected by two rods 121 with their ends fitting together, when the airbag pump is working, the rod 121 on either side of the connecting rod 12 at the upper and lower ends of the airbag pump body 1 will move relative to the other rod 121 as the corrugated pipe it is connected to compresses or extends. The laser displacement device 3 obtains the displacement data of the two rods 121 when they move by sensing the limiting structure 2 set at the position where the two rods 121 move relative to each other through laser sensing, and controls the stroke of the two rods 121 relative to each other based on the distance data detected by the laser displacement device 3. Secondly, the proximity sensor 4 can sense the position of the connecting plate 13 and monitor the stroke of the two rods 121 relative to each other by sensing the distance between the connecting plates 13.

[0025] Furthermore, the airbag pump monitors and feeds back the position of the rod 121 in the connecting rod 12 through the cooperation of the laser displacement device 3 and the limiting structure 2. The proximity sensor 4 can sense the position of the connecting plate 13 on its outer side and feed back the distance data as a signal to obtain the pumping volume of the airbag pump. Thus, the flow rate of the airbag pump is controlled based on the data fed back by the laser displacement device 3 and the proximity sensor 4. In addition, the limiting structure 2 can prevent the connecting rod 12 from overtraveling, making the control of the flow rate of the airbag pump more stable.

[0026] It needs to be further explained that, such as Figure 3 and Figure 4 As shown, the limiting structure 2 includes a second fixing seat 21, a first connecting end 22, and a first spring 23. The second fixing seat 21 is fixedly connected to the end of one of the rods 121 away from the connecting plate 13. The other rod 121 has an annular protrusion 122 in the middle. The first connecting end 22 is fitted to the rod 121 outside one end of the second fixing seat 21 and the rod 121 outside the protrusion 122. The first spring 23 is connected between the two first connecting ends 22.

[0027] In this process, after the fluid flows from the main body 1 of the airbag pump, one of the bellows inside the main body 1 moves towards the center of the airbag pump. Under the linkage of the connecting rod 12 and the connecting plate 13, it pushes the other bellows to extend. Through the expansion and contraction of the bellows on both sides of the airbag pump body 1, a structure is formed to continuously transport the fluid. When one of the bellows is compressed, the rod 121 connected to the bellows is pulled and moves towards the other rod 121. At this time, the first spring 23 is compressed. At the same time, when the other bellows extends, it drives the other rod 121 to move away from the center of the airbag pump body 1. After the bellows extends to a certain length, the movement of the other rod 121 away from the center of the airbag pump body 1 is limited by the elastic recovery of the first spring 23, and gradually pulls the other rod 121 to move in the opposite direction, thereby limiting the stroke of the connecting rod 12 and thus achieving the purpose of stabilizing the flow rate of the airbag pump.

[0028] It needs to be further explained that, such as Figure 5 and Figure 6 As shown, the limiting structure 2 includes a third fixing seat 24, a second connecting end 25, and a second spring 26. The third fixing seat 24 is fixedly connected to the end of one of the rods 121 away from the connecting plate 13. The end of the other rod 121 near the third fixing seat 24 is a small-diameter end 1211. The small-diameter end 1211 is fitted with the second connecting end 25 both near the third fixing seat 24 and away from the third fixing seat 24. The second spring 26 is connected between the two second connecting ends 25.

[0029] In this embodiment, the technical effect achieved is the same as that of the previous embodiment. When the two bellows in the main body 1 of the airbag pump are continuously extending or compressing, the compression and elastic recovery of the second spring 26 are used to limit the stroke of the two rods 121, thereby limiting the stroke of the connecting rod 12 and thus achieving the purpose of stabilizing the flow rate of the airbag pump.

[0030] Specifically, such as Figure 3 and Figure 5 As shown, the limiting structure 2 also includes a first limiting plate 5 and a second limiting plate 6. The second fixing seat 21 is fixedly connected to the first limiting plate 5, which extends in an L-shape away from the rod 121. The surface of the other rod 121 is fixedly connected to the second limiting plate 6, which extends in an L-shape away from the rod 121.

[0031] When the first spring 23 or the second spring 26 is compressed, the compression amount of the first spring 23 or the second spring 26 can be controlled by the abutment between the first limiting plate 5 and the second limiting plate 6, thereby limiting the relative travel of the two rods 121, and thus limiting the travel of the connecting rod 12 within the housing 11 to prevent the connecting rod 12 from overtraveling.

[0032] More specifically, such as Figure 3 and Figure 5 As shown, the proximal ends of the first limiting plate 5 and the second limiting plate 6 are parallel to each other, and the ends of the first limiting plate 5 and the second limiting plate 6 away from their fixed connection ends are on the same horizontal straight line as the laser emitting end of the laser displacement device 3.

[0033] Because the ends of the first limiting plate 5 and the second limiting plate 6 are vertical, the laser emitted by the laser emitting end of the laser displacement device 3 can be blocked by the ends of the first limiting plate 5 and the second limiting plate 6, making the control of the stroke of the rod 121 by the laser displacement device 3 more stable.

[0034] It needs to be further explained that, such as Figure 7 As shown, the end of the connector 15 located outside the housing 11 is a first terminal 151 for wiring of the proximity sensor 4, and a first locking nut 152 is fitted on the outside of the first terminal 151.

[0035] The proximity sensor 4 is connected to the wire through the first terminal 151 to realize the wiring of the proximity sensor 4. By tightening the first locking nut 152 to the first terminal 151, the line connecting the proximity sensor 4 to the first terminal 151 is fixed to improve the stability of the line connection of the proximity sensor 4 during operation and ensure that the proximity sensor 4 can operate normally.

[0036] It needs to be further explained that, such as Figure 8 As shown, the wall surface of the housing 11 outside the laser displacement device 3 is provided with a second terminal 16 for wiring of the laser displacement device 3, and a second locking nut 161 is fitted on the outside of the second terminal 16.

[0037] The laser displacement device 3 is connected to the wires through the second terminal 16, thereby realizing the wiring of the laser displacement device 3. After the wiring is completed, the second locking nut 161 on the second terminal 16 can be tightened to fix the line connecting the second terminal 16 to the laser displacement device 3, so as to improve the stability of the line connection of the laser displacement device 3 during operation and ensure that the laser displacement device 3 can operate normally.

[0038] It needs to be further explained that, such as Figure 1 andFigure 2 As shown, a protective cover 7 is fixedly connected to the upper end of the housing 11 to seal the connecting rod 12 and the laser displacement device 3.

[0039] The protective cover 7 surrounds the connecting rod 12 and the laser displacement device 3, which can prevent the connecting rod 12 and the laser displacement device 3 from being impacted by external forces and reduce the risk of damage to the connecting rod 12 and the laser displacement device 3.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
