Abstract
The utility model discloses low tension flow tables.Including current meter body, current meter body includes housing, dial plate and the pointer being arranged on dial plate, the graduation mark of fan-shaped distribution is provided on dial plate and is arranged on the limited block of graduation mark both sides, oval buffer stopper is provided on pointer, thimble is provided on oval buffer stopper, the groove body with oval buffer stopper cooperation is offered on limited block, groove body bottom is provided with the button switch with thimble cooperation, the groove connected with groove body is circumferentially provided on groove body inner wall simultaneously, Buffer Unit is both provided in each groove.The cooperation that the utility model passes through the groove body on oval buffer stopper and limited block, and after oval buffer stopper is entered in the groove body on limited block, automatic ejection air bag carries out oval buffer stopper flexible reduction of speed, so that the collision of pointer is changed to flexible impact, reduce the impact that pointer is subject to, so as to avoid pointer bending.
Description
Technical field
The utility model is related to ammeter technical fields, especially low tension flow table.
Background technology
Ammeter is manufactured according to electrical conductor effect magnetic field force induced in magnetic field.There is a permanent magnetism inside ammeter
Body generates magnetic field in interpolar, and there are one coil in magnetic field, respectively there are one hairspring spring, spring respectively connects electric current at coil both ends
One binding post of table is connected between spring and coil by a shaft, and in shaft compared with the front end of ammeter, there are one refer to
Pin.
In electronic equipment detection, ammeter is a kind of common detecting instrument.Ammeter when in use, by ammeter string
It connecing in circuit, electric current is flowed into from "+" binding post, is flowed out from "-" binding post, during use, positive antipole reversal connection during because of wiring,
Or measurement is more than ammeter range, causes pointer and the quick rigid collision of limiter, so as to cause pointer bending, influences ammeter
Normal use.
Utility model content
The utility model be directed to deficiency of the prior art, provide low tension flow table, by oval buffer stopper with
The cooperation of groove body on limited block, and after oval buffer stopper is entered in the groove body on limited block, automatic ejection air bag
Flexible reduction of speed is carried out to oval buffer stopper so that the collision of pointer is changed to flexible impact, reduces the impact that pointer is subject to, so as to
Avoid pointer bending.
In order to solve the above technical problems, the utility model is addressed by following technical proposals：Low tension flow table, including
Current meter body, the current meter body include housing, dial plate and the pointer being arranged on the dial plate, on the dial plate
It is provided with the graduation mark of fan-shaped distribution and is arranged on the limited block of the graduation mark both sides, ellipse is provided on the pointer
Buffer stopper is provided with thimble on the ellipse buffer stopper, is offered on the limited block and the oval buffer stopper coordinates
Groove body, the groove body bottom is provided with the button switch with thimble cooperation, while is circumferentially set on the groove body inner wall
The groove connected with the groove body is equipped with, Buffer Unit is both provided in each groove；
The Buffer Unit include being arranged on cylinder in the groove, the push rod coordinated with the cylinder and with it is described
The air bag that push rod is connected, the cylinder are electrically connected with the button switch.
The beneficial effects of the utility model are：The utility model is matched somebody with somebody by oval buffer stopper and the groove body on limited block
It closes, and after oval buffer stopper is entered in the groove body on limited block, automatic ejection air bag carries out oval buffer stopper
Flexible reduction of speed so that the collision of pointer is changed to flexible impact, reduces the impact that pointer is subject to, so as to avoid pointer bending.
Description of the drawings
Fig. 1 is utility model diagram.
Fig. 2 is the enlarged diagram at D in Fig. 1.
Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings：Referring to Fig. 1 and Fig. 2,
Low tension flow table, including current meter body, the current meter body includes housing 1, dial plate 2 and is arranged on the dial plate 2
On pointer 3, the graduation mark of fan-shaped distribution is provided on the dial plate 2 and is arranged on the limited block 4 of the graduation mark both sides,
Oval buffer stopper 31 is provided on the pointer 3, thimble 32, the limited block 4 are provided on the ellipse buffer stopper 31
On offer the groove body 41 coordinated with the oval buffer stopper 31,41 bottom of groove body is provided with to be coordinated with the thimble 32
Button switch 42, while the groove 43, Mei Gesuo connected with the groove body 41 is circumferentially provided on 41 inner wall of groove body
It states in groove 43 and is both provided with Buffer Unit.
The Buffer Unit include being arranged on cylinder 51 in the groove 43, with the push rod 52 of the cylinder 51 cooperation with
And the air bag 53 being connected with the push rod 52, the cylinder 51 are electrically connected with the button switch 42.
After oval buffer stopper is entered in the groove body on limited block, thimble presses button switch, and cylinder starts
Cylinder is released, multiple air bags clamp oval buffer stopper, flexible reduction of speed are carried out to oval buffer stopper so that the collision of pointer changes
For flexible impact, reduce the impact that pointer is subject to, so as to avoid pointer bending.
Above example is only to illustrate the technical solution of the utility model, rather than its limitations；Although with reference to foregoing reality
Example is applied the utility model is described in detail, it will be understood by those of ordinary skill in the art that：It still can be to preceding
The technical solution recorded in each embodiment is stated to modify or carry out equivalent substitution to which part technical characteristic；And these
Modification is replaced, and the essence of appropriate technical solution is not made to depart from the spirit and model of various embodiments of the utility model technical solution
It encloses.
