A kind of have a barometric tyre pump of rotating disc type, as shown in Figures 4 to 6, be provided with the pump housing 200, the deep bid 300 be communicated with the pump housing 200, with deep bid 300, export tire connecting pipe 400 and the rain glass be communicated with respectively, a part of gas that deep bid 300 produces the pump housing 200 inputs to doughnut by tire connecting pipe 400, and another part gas inputs to rain glass and carries out the air pressure detection.
Concrete, deep bid 300 outlets are provided with tire interface and rain glass interface.The tire interface is connected with tire connecting pipe 400, and the portion gas that the pump housing 200 is produced inputs to doughnut; The rain glass interface is connected with rain glass, so that portion gas is delivered to rain glass, is detected.
The pump housing 200 drives by actuating unit, thereby the power that actuating unit produces drives the reciprocating motion of the pistons in the pump housing 200 to be compressed the gas in the pump housing 200 chambeies by gear train, obtains gas.
The structure of the pump housing 200, actuating unit structure and gear train is general knowledge known in this field, realizes that the structure of this function has multiple different form, at this, does not enumerate.Only with a kind of structure, describe, in the present embodiment, actuating unit is set to a motor herein, and gear train comprises pinion wheel, gear wheel and drive link.Pinion wheel is fixedly sleeved in the motor drive shaft of motor, gear wheel and pinion wheel engagement, and gear wheel is provided with a cam, and drive link one end and cam are flexibly connected, and the drive link other end is fixedly connected with the piston of the pump housing 200.Its principle of work is, under the rotation of motor, motor drive shaft drives pinion wheel and rotates together, pinion wheel drives gear wheel also to rotate together thereupon, cam driven connecting rod to-and-fro movement on gear wheel, thereby drive the reciprocating motion of the pistons in the pump housing 200, realize that the pump housing 200 cavity 112 internal gas pressures are compressed according to certain frequency, thereby produce gas.
The gas that the pump housing 200 produces is delivered to deep bid 300, and deep bid 300 inputs to doughnut by a part of gas by tire connecting pipe 400, and another part gas is delivered to rain glass and carries out the air pressure detection.In order accurately to control and to enter gaseous tension in doughnut, need accurately to detect the air pressure size.Therefore barometric precision is extremely important.
Rain glass in the present embodiment is set to rotating disc type rain glass 100, as shown in Figure 1 to Figure 3, is provided with core body 110 and indicator dish 118.
Concrete, mobile terminal 1161 is provided with assembling plush copper 1162, and piston component 115 is provided with fitting recess, assembling plush copper 1162 and fitting recess sealing assembling.By the setting of assembling plush copper 1162 and fitting recess, can be by the close fit of mobile terminal 1161 and piston component 115.It should be noted that, also mobile terminal 1161 and piston component 115 directly can be set to integrative-structure, there are characteristics simple in structure, easy to assembly.
The drive end 1163 of carriage release lever 116 is provided with a plurality of sawtooth 1164, and actuator 117 is set to gear 1171, and gear shaft 1172 activities of gear 1171 are assemblied in support body 111, and pointer 119 fixedly is assemblied in gear shaft 1172, and sawtooth 1164 is complementary with gear 1171.When carriage release lever 116 moves along cavity 112, the drive end 1163 of carriage release lever 116 is exposed to the length of cavity 112 also along with variation, thereby make sawtooth 1164 driven gears 1171 rotate, gear 1171 driven gear axles 1172 rotate, and gear shaft 1172 drives pointer 119 and rotates and carry out the pressure demonstration at indicator dish 118.
Preferably, the dial plate of indicator dish 118 is set to the uniform dial plate of scale.
The elastic force of this rotating disc type instrument spring 114 and the deformation quantity of spring 114 are linear relationship, gear 1171 is also linear relationship with the mobile relation of sawtooth 1164, therefore can realize the rotation of pointer 119 and the variable quantity relation in direct ratio of air pressure, have simple in structure, detect characteristics accurate, with low cost.
Of the present utility model have a barometric tyre pump of rotating disc type, its principle of work is such: the gas produced when air pump is delivered to the air intake opening 113 of rotating disc type rain glass 100 by deep bid 300 outlets, when gas enters cavity 112 by air intake opening 113, along with increasing of inputted gas flow, air pressure in the cavity 112 of air intake opening 113 ends increases, to promote piston component 115 Compress Springs 114 and move towards the Way out of cavity 112, piston component 115 promotes carriage release lever 116 and also moves towards the Way out of cavity 112, now, the sawtooth 1164 of drive end 1163 will drive the gear 1171 of actuator 117 to rotate, the gear shaft 1172 of gear 1171 is rotated with the pointer 119 of chain meter dish 118.And when cavity 112 internal gas pressures of air intake opening 113 positions reduce, spring 114 promotes piston reverses direction and moves under the effect of restoring force, piston driving carriage release lever 116 oppositely moves, the drive end 1163 of carriage release lever 116 takes actuator 117 to and also oppositely moves, and realizes showing by the instrument dish effect of the air pressure size of gas.Evidence, the error of this air pump is 2psi, therefore not only have simple in structure but also detect accurate, with low cost.By rotating disc type rain glass 100 is set, for portable dam, as tire pump or Portable air pump, not only volume is little but also precision is high, can improve the performance of air pump.
Finally should be noted that; above embodiment is only in order to the technical solution of the utility model to be described but not to the restriction of the utility model protection domain; although with reference to preferred embodiment, the utility model is explained in detail; those of ordinary skill in the art is to be understood that; can modify or be equal to replacement the technical solution of the utility model, and not break away from essence and the scope of technical solutions of the utility model.
