Description

Diaphragm type plastic splint movement small pressure table
[technical field]
The utility model relates to a kind of diaphragm type plastics movement small pressure table, belongs to the measurement mechanism field.
[background technology]
The instrument of gas, fluid pressure in the indication mechanism is typically provided with the movement that metal material (as copper) is made in the prior art.Manometric watchcase bottom is connected with gas, liquid systems, and be welded with diaphragm in intercommunicating pore upper shed place, when the pressure of gas, liquid systems increases when causing the deformation of diaphragm projection, the diaphragm of projection drives the induction end and the transmission component motion of movement, and finally drives the beat of pointer and indicate force value on the index dial; When the pressure of gas, liquid systems reduced, diaphragm was replied deformation, and the transmission component in the movement drives pointer and resets gradually.The tensimeter of this structure, the movement of its metal material, particularly copper movement, cost height, processing inconvenience.
[utility model content]
The technical assignment of the technical problems to be solved in the utility model and proposition is the defective that overcomes prior art, and the diaphragm type plastic splint movement small pressure table of a kind of low cost of manufacture, easy to process, sensitivity safe in utilization is provided.For this reason, the utility model adopts following technical scheme:
Diaphragm type plastic splint movement small pressure table, be provided with last C shape collar, index dial and the movement showing lid, pointer, be embedded in the watchcase madial wall in the watchcase from top to bottom successively, upper shed place of watchcase bottom intercommunicating pore is provided with diaphragm, it is characterized in that being provided with between described movement and the diaphragm sheet locating part that central authorities have the flange through hole and are connected to the watchcase inwall, the induction end of movement is passed the flange through hole and diaphragm touches, and is provided with the following C shape collar that is embedded in the watchcase madial wall between described locating part and the movement.When the pressure of gas, liquid systems increases when causing the deformation of diaphragm projection, diaphragm pushes induction end and drives transmission component motion in the movement, the oscilaltion campaign of diaphragm is changed into the horizontal hunting of pointer; When pressure surpassed normal measurement range, owing to set up locating part above diaphragm, excessively deformation of diaphragm can protect movement indeformable, thereby reduced the possibility that diaphragm ejects movement watchcase.Therefore, can realize that the tensimeter of identical measurement range adopts other materials cheap, easy to process (as plastics) to make movement, guarantee product quality and safe in utilization in, reduce production costs.Following C shape collar is installed in the annular groove of watchcase madial wall, and the restriction locating part is promoted to rise by diaphragm and makes the plastics movement be out of shape, deviate from watchcase, further ensures product quality and safe in utilization.The flange of flange through hole is thick than the locating part remainder, can improve banking stop intensity.
For the improving and replenishing of technique scheme, can increase following technical characterictic or its combination:
Described movement comprises the upper and lower clamping plate of the movement that is parallel to each other, be provided with the vertical column of complex root between the upper and lower clamping plate of movement, upper and lower clamping plate of movement and column are made by plastic material, the movement lower plate is provided with the push rod as the activity of described movement induction end, push rod upper end cooperates with sector gear on being socketed in a vertical shaft, the swinging end of sector gear cooperates with the tooth axle that vertically passes the movement train wheel bridge, and tooth axle bottom is provided with hairspring.During work, along with gas, liquid systems pressure increase, diaphragm pushes push rod and swings in vertical plane, drives sector gear and swings in the horizontal direction, promotes the tooth axle and horizontally rotates around vertical axle center with the pointer that is socketed in tooth axle upper end; Adopt plastic material to make upper and lower clamping plate of movement and column, obviously reduced production cost, also save the various operations when adopting metal material to make, directly the injection moulding manufacturing is easy to process, and hairspring is used to help tooth axle and pointer to reset.
Described diaphragm central authorities are inner fovea part, the diaphragm periphery is provided with and inner fovea part annular groove in the same way, the watchcase inner bottom part is provided with holding tank, the annular groove interlocking is in holding tank, described annular groove bottom and annular groove lateral wall and the welding of watchcase inside surface, the inner fovea part bottom surface is higher than the annular groove bottom, and described annular groove madial wall peak is lower than annular groove lateral wall peak, the flange of flange through hole is suspended from the inner fovea part, and movement induction end and inner fovea part upper surface touch.The operate portions of diaphragm is all built on stilts inner fovea part in upper and lower surface, the elevating movement freedom, and induction is sensitive; When pressure surpasses normal measurement range; inner fovea part stretches the flange through hole peritreme that the back upper surface is against the sheet locating part; can not continue to rise and push induction end; inner fovea part continues expansion and stretches flat gradually; annular groove madial wall around the extruding is outwards expanded and is made the annular groove lateral wall compress the watchcase inwall, thereby vertical pressure is decomposed to side direction, makes the pressure of case side wall absorption portion excess; the protection movement is indeformable, has reduced the possibility that diaphragm ejects movement watchcase.Therefore, available plastics are made movement and are assembled out the identical tensimeter of pressure-bearing scope, guarantee product quality and safe in utilization in, reduce production costs.
Described column is wholely set on the movement lower plate, and the movement train wheel bridge is provided with the leghole of corresponding column.Column is inserted corresponding leghole can fasten the upper and lower clamping plate of movement, and the assembling movement is convenient and swift.
The utility model reaches C shape collar down by setting up locating part, limiting diaphragm exceeds measurement range movement in season distortion even deviates from watchcase at pressure, the vertical pressure that the diaphragm of structure uniqueness can will exceed measurement range decomposes to side direction, make case side wall absorb extraordinary pressure, further reduced the possibility that diaphragm ejects movement watchcase, guarantee under measurement range and the prerequisite safe in utilization thereby be implemented in, adopt plastics to make the upper and lower clamping plate and the column of movement, obviously reduce production cost, and be convenient to processing.
