Trapped fuel slot is equipped with inside the driving gear disc, the driving gear disc is equipped with the pouring orifice that is connected with trapped fuel slot, institute
Driving gear disc is stated equipped with multiple for intercommunicating pore, described intercommunicating pore one end is connected with trapped fuel slot, and the other end extends to actively
On the side of teeth.
The driving gear disc is equipped with the active axis hole being connected with active rotating shaft, and limit is equipped on the inner wall of active axis hole
Position side channel, the limit side channel are connected with active axis hole.
The present invention has the advantages that
The invention discloses a kind of imitative ratchet gear groups, can be adapted for gas meter, flow meter, imitative ratchet gear disclosed by the invention
Group appearance is similar with gear set, but has ratchet mechanism non-return effect, then realize that driving gear and driven gear can rotate
While, moreover it is possible to realize the non-return effect of ratchet mechanism.

Specific embodiment
Specific embodiment of the present utility model is made into one by the description to optimum embodiment below against attached drawing
Step detailed description.
A kind of imitative ratchet mechanism gear set in gas meter, flow meter, including driving gear and driven gear, driving gear packet
The active teeth 2 for including driving gear disc 1 and being arranged on 1 periphery of driving gear disc；Driven gear include driven fluted disc 4 and setting from
Driven teeth 5 on 4 periphery of active toothed disk；The side of active teeth 2 is equipped with retention bead 3, and driven 5 section of teeth is arc-shaped；
It is meshed from teeth with active teeth 2；Through the above structure, the invention discloses a kind of imitative ratchet gear group, can be adapted for
Gas meter, flow meter can be applicable to other places, be arranged according to actual requirement except of course that being suitable for gas meter, flow meter, while the present invention
Disclosed imitative ratchet gear group appearance is similar with gear set, and function and conventional gears group are also similar, but the gear set has spine
While taking turns non-return effect possessed by mechanism, then realize that driving gear and driven gear can rotate, moreover it is possible to realize ratchet machine
The non-return effect of structure.
Preferably, retention bead 3 is equipped with the clamping groove for being mutually clamped with the tooth top of driven teeth 5 in the present invention
31；It by the cooperation of clamping groove 31 and driven 5 tooth top of teeth, can quickly be clamped, realize the card of driving gear and driven gear
Connect, can preferably realize that driven gear limits the press of driving gear, that is to say power that driven gear is subject to be directed to from
The center of moving gear, driven gear and driving gear cooperation are in state even at the cost of one's life, to play return-stopping function.
Preferably, the side that active teeth 2 and driven teeth 5 are meshed in the present invention is equipped with gear friction safety
Line 21, because of gear set disclosed by the invention, driving gear is engaged with driven gear is, each teeth of driving gear and driven tooth
Wheel each teeth be meshed often the field of conjugate action be single side, for a long time operate, will cause capping abrasion it is larger, so in driving tooth
Each teeth of wheel are equipped with gear friction safety line 21 close to the side of the field of conjugate action, when abrasion is more than this bar line, in order to more
Effect is engaged well, needs replacing driving gear or driven gear.
Preferably, the side that active teeth 2 and driven teeth 5 are meshed in the present invention is equipped with elastic layer；It reduces
Frictional force when driving gear is engaged with driven gear reduces noise.
Preferably, being equipped with trapped fuel slot 8 in the present invention inside driving gear disc 1, driving gear disc 1 is equipped with and trapped fuel slot 8
Be connected pouring orifice 6, and driving gear disc 1 is used for intercommunicating pore 7 equipped with multiple, and 7 one end of intercommunicating pore is connected with trapped fuel slot 8, another
End extends on the side of active teeth 2；By the setting of trapped fuel slot 8, pouring orifice 6 and intercommunicating pore 7, driving tooth may be implemented
The lubrication of wheel and driven gear reduces the abrasion of driving gear and driven gear.
Preferably, driving gear disc 1 is equipped with the active axis hole 22 being connected with active rotating shaft in the present invention, actively
The inner wall of axis hole 22 is equipped with limit side channel 23, and limit side channel 23 is connected with active axis hole 22, passes through setting for limit side channel 23
It sets, so that active axis hole forms a similar criss-cross notch with limit side channel 23, corresponding active rotating shaft end also is provided with
Similar criss-cross structure, when the two is connected with each other, because of the setting of limit side channel, so that active rotating shaft will not be with respect to driving shaft
Hole rotation reduces the opposite sliding of active rotating shaft and active axis hole.
Obvious the utility model specific implementation is not subject to the restrictions described above, as long as using method concept of the invention
The improvement of the various unsubstantialities carried out with technical solution, it is within the scope of the present invention.
