Summary of the invention
In order to solve the above-mentioned technical problem, the purpose of this utility model is to provide a kind of transmission knots of pressure sensor
Structure.
The utility model is achieved through the following technical solutions:
A kind of drive mechanism of pressure sensor has the ontology of water inlet including top, is placed with pressure in the ontology
Force snesor is additionally provided with the fixing seat positioned at water inlet water outlet in the ontology, is provided with and intakes in the fixing seat
The opening that matches of mouth, the diaphragm being provided between water inlet and opening between the fixing seat and ontology are set in the opening
It is equipped with the cylinder that can be moved up and down, one end of the cylinder couples with diaphragm cooperation, the other end and pressure sensing of the cylinder
The microswitch of device cooperates connection, and the diameter of the opening is gradually reduced from bottom to top.
In the utility model embodiment, connecting rod is provided in the ontology below fixing seat, the cylinder setting is even
In the middle part of bar, described connecting rod one end is hinged with ontology, and the connecting rod other end couples with setting in the cooperation of intrinsic spring.
In the utility model embodiment, setting one is used for the groove of placement force sensor, the groove in the ontology
Bottom is provided with the clamping block for pressure sensors.
In the utility model embodiment, a pillar is additionally provided in the bottom portion of groove, the pillar periphery is arranged with
The upper end of the spring stated, the spring couples with the cooperation of the lower section of the connecting rod other end.
In the utility model embodiment, one end of the connecting rod is provided with the pin shaft with this mates.
A kind of drive mechanism of pressure sensor of the utility model has the following beneficial effects: that the utility model solves
The drive mechanism middle column body by hydraulic pressure control being made of diaphragm, cylinder and spring not stuck phenomenon, make this drive mechanism can
It is higher by property.
Detailed description of the invention
It, below will be to institute in embodiment or description of the prior art in order to illustrate more clearly of the technical solution of the utility model
Attached drawing to be used is needed to be briefly described, it should be apparent that, the accompanying drawings in the following description is only some of the utility model
Embodiment for those of ordinary skill in the art without creative efforts, can also be attached according to these
Figure obtains other attached drawings.
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the explosive view of the utility model.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, to the technical solution in inventive embodiments carry out it is clear,
It is fully described by, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole implementation
Example.Based on the embodiments of the present invention, those of ordinary skill in the art are obtained without making creative work
The every other embodiment obtained, fall within the protection scope of the utility model.
Reference book attached drawing, a kind of drive mechanism of pressure sensor have the ontology 10 of water inlet 11 including top,
It is placed with pressure sensor 20 in the ontology, the fixing seat 30 positioned at water inlet water outlet, institute are additionally provided in the ontology
State the opening 31 for being provided in fixing seat and matching with water inlet, be provided between the fixing seat and ontology positioned at water inlet with open
Diaphragm 40 between mouthful is provided with the cylinder 51 that can be moved up and down in the opening, and one end of the cylinder cooperates with diaphragm to be coupled,
The other end of the cylinder couples with the cooperation of the microswitch 21 of pressure sensor, and the diameter of the opening gradually subtracts from bottom to top
It is small.
Specifically: connecting rod 52 is provided in the ontology below fixing seat, the cylinder is arranged in the middle part of connecting rod, institute
It states connecting rod one end to be hinged with ontology, the connecting rod other end couples with setting in the cooperation of intrinsic spring 60.
In particular: setting one is used for the groove 12 of placement force sensor in the ontology, and the bottom portion of groove is set
It is equipped with the clamping block 13 for pressure sensors.A pillar 14, the pillar periphery are additionally provided in the bottom portion of groove
It is arranged with above-mentioned spring, the upper end of the spring couples with the cooperation of the lower section of the connecting rod other end.One end of the connecting rod is arranged
There is the pin shaft 53 with this mates.
The new structural design of drive mechanism in the utility model is by diaphragm, connecting rod, cylinder, fixing seat, groups of springs
At be by the drive mechanism of hydraulic pressure control, water inlet water inlet hydraulic pressure effect under, column is transmitted the force to by diaphragm
Body, when hydraulic pressure increases, when the power at hydraulic pressure end is greater than spring force, cylinder, which moves down, is pressed onto microswitch, completes control, works as water
When pressure reduces, when the power at hydraulic pressure end is less than spring force, cylinder resets under the action of spring is to connecting rod, and microswitch disengages, complete
At control.The improvement of this new technology is: the circular hole fit clearance of the cylinder being in contact with diaphragm and fixing seat reduces, and fixed
Seat opening increases chamfering, and making cylinder and opening is not in stuck phenomenon, improves the reliability of transmission mechanism.
Above disclosed is only the preferred embodiment of the utility model, certainly cannot be practical new to limit this with this
The interest field of type, therefore equivalent variations made according to the claim of the utility model still belong to the model that the utility model is covered
It encloses.
