Abstract
The utility model provides a high-precision liquid pressure detecting device. A bracket is hinged with a driving gear fixedly connected with an inclined rocker arm, and the other end of the rocker arm is hinged with a piston sealed in a container. The bracket further is hinged with a driven gear, and the driving gear is meshed with the driven gear. The bracket is slid with a rack, the rack is slid in a sliding chute of the bracket, one end of the rack is fixedly connected with a top rod, and the top rod contacts a contact head of a pressure sensor. Through injecting the liquid into the container and under the effect of the fluid pressure, the piston moves and the movement thereof leads the rotation of the rocker arm, a end of which connects with the driving gear rotating leaded by the rocker arm, the meshed driven gear is rotated as well. Due to the driven gear meshing with the rack which slipes along the horizontal direction under the effect of the driven gear, a contact of the pressure sensor is squeezed and then a pressure signal is detected to measure a pressure value of the liquid.
Description
Technical field
The utility model relates to a kind of checkout equipment, is specifically related to a kind of high-precision liquid pressure-detecting device.
Background technology
Liquid pressure is to be produced by the mobility of liquid, even if do not have gravity still to have pressure, but has not had the downward pressure of gravity liquid just little.Because the pressure to downward of general liquid is larger than sidewall, there is no gravity, that is equally large with sidewall with regard to downward pressure.So the reason producing is because due to the mobility of liquid.At present, do not have the measuring equipment of establishing simple in structure can comparatively accurately measure the downward pressure of liquid.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, can accurately measure the checkout equipment of fluid pressure.
For achieving the above object, the technical solution of the utility model is: high-precision liquid pressure-detecting device, comprise support, on described support, be hinged with a driving gear, on described driving gear, be fixedly connected with the rocking arm of inclination, the other end of described rocking arm is hinged with a piston, and described piston seal is in container; On described support, be also hinged with a follower gear, described follower gear and driving gear engagement; On described support, slide and be provided with a tooth bar, described tooth bar is slidably arranged in the chute on support, and described tooth bar one end is fixedly connected with a push rod, the contact of described push rod and pressure transducer.
While adopting technique scheme, by filling liquid in container, under the effect of fluid pressure, piston moves, the moving belt of piston shakes arm and rotates, and the driving gear that rocking arm end connects rotates under the drive of rocking arm, drives the follower gear engaging with it to rotate.Owing to being engaged with a tooth bar on follower gear, tooth bar slides in the horizontal direction under the effect of follower gear, thus the contact of squeeze pressure sensor, thus pressure signal can be detected, measure the force value of liquid.The utility model is simple in structure, can accurately measure by the movement of tooth bar the pressure of liquid.
Further, described support vertically arranges, and described driving gear, rocking arm and follower gear are arranged on the homonymy of support.
Further, the back side of described tooth bar is provided with angle sheave.Angle sheave is set can be supported better to tooth bar.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of the utility model high-precision liquid pressure-detecting device embodiment 1.
Embodiment
As shown in Figure 1, the utility model high-precision liquid pressure-detecting device, comprises vertical support 1, on support 1, be hinged with a driving gear 2, on driving gear 2, be fixedly connected with the rocking arm 3 of inclination, the other end of rocking arm 3 is hinged with a piston 4, and piston 4 is sealed in container 5.On support 1, be also hinged with a follower gear 6, follower gear 6 and driving gear 2 engage; On support 1, slide and be provided with a tooth bar 7, tooth bar 7 is slidably arranged in the chute on support 1, and tooth bar 7 one end are fixedly connected with a push rod 8, the contact of push rod 8 and pressure transducer 9.The back side of tooth bar 7 is provided with angle sheave 71.Angle sheave 71 is set can be supported better to tooth bar 7.
When use, by the past interior filling liquid of container 5, under the effect of fluid pressure, piston 4 moves, the moving belt of piston 4 shakes arm 3 and rotates, and the driving gear 2 that rocking arm 3 ends connect rotates under the drive of rocking arm 3, drives the follower gear 6 engaging with it to rotate.Owing to being engaged with a tooth bar 7 on follower gear 6, tooth bar 7 slides in the horizontal direction under the effect of follower gear 6, thus the contact of squeeze pressure sensor 9, thus pressure signal can be detected, measure the force value of liquid.The utility model is simple in structure, can accurately measure by the movement of tooth bar 7 pressure of liquid.
Above-described is only preferred implementation of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
