Description
Technical Field
The utility model relates to an embedded manometer for detecting aerify product atmospheric pressure.
Background
The working principle of the pressure gauge is that the pressure deformation is transmitted to the pointer through the elastic deformation of sensitive elements (Bourdon tube, bellows and bellows) in the gauge and then through a conversion mechanism of a movement in the gauge, so that the pointer is caused to rotate to display the pressure.
The pressure gauge mainly comprises a bellows type pressure gauge, a spring type pressure gauge, a bellows type pressure gauge, a shock-proof pressure gauge, a digital pressure gauge and the like. For example, a spring tube pressure gauge structure is disclosed in the chinese utility model patent No. ZL200920199778.4 (publication No. CN 201527321U). When the special spring tube is pressed by medium (such as gas), its free end can be moved outwards, and then the connecting rod can be used for driving sector gear and small gear to rotate so as to make the pointer rotate clockwise by an angle. The greater the pressure of the medium, the greater the angle of rotation of the pointer. At this time, the scale value indicated by the pointer on the dial of the pressure gauge is the numerical value of the measured air pressure. When the pressure is reduced, the spring elbow will contract inward, returning the pointer to the corresponding position. When the pressure disappears, the spring bend returns to the original shape, and the pointer returns to the initial point (zero position) with the help of the action of the balance spring. The spring tube type pressure gauge has the advantages of compact structure, higher accuracy, wide measuring range, convenient use and the like, and is mainly used for measuring the medium pressure values in a boiler barrel, a header and a pipeline.
The existing pressure gauge structure has the defects that the volume of the pressure gauge is large due to the complex structure of the transmission part, the requirements on materials and manufacturing precision are high, the cost is high, the anti-seismic effect of the lever or gear transmission structure is extremely poor, and the lever or gear transmission part of the pressure gauge is damaged when the pressure gauge falls on the bottom surface.
Therefore, the applicant applies for a Chinese invention patent 'a pressure gauge' with a patent number ZL201410344095.9 (publication number CN 104236784B). The conversion structure in the pressure gauge mainly comprises a transmission rod and a transmission seat, the transmission seat can move up and down under the action of air pressure drive introduced from an introduction hole and a support spring through the thread matching between the transmission rod and the transmission seat and is converted into the rotary motion of the transmission rod, and finally, the pointer is driven to rotate.
However, the pressure gauge has the following technical problems that after the existing pressure gauge is installed on an inflatable product (a paddle board and an inflatable boat), the head of the pressure gauge protrudes out of the surface of the product by a large section, the appearance of the product is influenced, and the pressure gauge is not beneficial to use.
Currently, in the inflation industry, wiredrawing fabrics are often used when developing new products that are both light and hard. Such as those used for SUP boards, surfboards, kayaks, etc., but also tents, etc. The pressure gauge is not designed for wiredrawing fabrics. The wire drawing is easy to enter the pressure gauge, and the use precision of the pressure gauge is influenced.
