Specific embodiment

The technical solution of the utility model is clearly and completely described below in conjunction with attached drawing, it is clear that described Embodiment is the utility model a part of the embodiment, instead of all the embodiments.Based on the embodiments of the present invention, originally Field those of ordinary skill every other embodiment obtained without making creative work belongs to practical Novel protected range.

It is in the description of the present invention, it should be noted that term " center ", "upper", "lower", "left", "right", " perpendicular Directly ", the orientation or positional relationship of the instructions such as "horizontal", "inner", "outside" is to be based on the orientation or positional relationship shown in the drawings, and is only For ease of description the utility model and simplify description, rather than the device or element of indication or suggestion meaning must have it is specific Orientation, be constructed and operated in a specific orientation, therefore should not be understood as limiting the present invention.

In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " is pacified Dress ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary, It can be the connection of two member interior walls.For the ordinary skill in the art, above-mentioned art can be understood with concrete condition The concrete meaning of language in the present invention.

As depicted in figs. 1 and 2, the gear 4 of motor valve for gas meter, is arranged in the valve body 1 of motor valve, including with motor 8 output axis connection, the first gear portion 41 moved with the output shaft, and connect to form rotation stop proof structure and energy with screw rod 3 Drive the rotation of screw rod 3 that the kinetic energy of the motor 8 is passed to the second gear portion 42 of stud set component 2；First tooth The inner wall of wheel portion 41 forms sawtooth, is inner gear structure, cooperates with the output shaft gear 4, the second gear portion 42 is Smooth surface, the first gear portion 41 and second gear portion 42 are integrally formed；The screw rod 3 includes connecting with stud set component 2 The first breechblock 31 connect, and the second breechblock 32 being connect with the gear 4, the company of second breechblock 32 and second gear portion 42 The place of connecing forms the disk 321 with the second gear portion 42 cooperation, shape between the disk 321 and the second gear portion 42 At rotation stop proof structure；The screw rod 3 can drive the stud set component 2 to move up and down, and be turned on or off out the valve body 1 Gas outlet.

Since the motor 8 is located at the lower section of the valve body 1, and stud set component 2 is located at the upper of the valve body 1 Side is that the kinetic energy of the underlying motor 8 is transmitted on the stud set component 2 of top, dynamic for that can facilitate The straight line transmitting of energy, while rotation stop proof structure can be formed again, the gear 4 is divided into the first gear portion 41 and second gear The kinetic energy of the motor 8 can be passed to the screw rod 3 by 42 two parts of portion, the gear 4 described in this way, then the screw rod 3 is allowed to transmit Give the stud cover component 2, while again can with the screw rod 3 formed rotation stop proof structure, when closing valve and the screw rod 3 cooperate into Row skids, and carries out effective kinetic energy transmitting and blocking rotation, structure is simple, also optimizes the structure of the motor valve, reduces function Consumption, extends the service life of the motor valve.

In addition, it is necessary to explanation, in the present embodiment, the preferred embodiment in the first gear portion 41 of the gear 4 is interior External tooth wheel construction also can be selected, as long as can nibble with the output shaft of the motor 8 in gear structure in other examples It closes, transmits kinetic energy.

Further, first breechblock 31 is threadedly coupled with stud set component 2, under the action of screw rod 3, institute Stating stud set component 2 can move up and down, and second breechblock 32 also forms the support portion 323 for being used to support the screw rod 3, institute The top for stating motor 8 is provided with the supporting table 7 of the support slot rotated suitable for the insertion of the support portion 323 of the screw rod 3.

Further, the support portion 323 of the relatively described screw rod 3 in the first gear portion 41 is offered suitable for the support portion 323 pass through and are inserted into the gear hole 411 of the supporting table 7；Above structure is fixed in order to which screw rod 3 can pass through gear hole 411 On valve body 1.

Further, as shown in Fig. 3, Fig. 4 and Fig. 5, the rotation stop proof structure includes through the described of the disk 321 setting Cross-drilled hole 322, the bias piece 5 being mounted in the cross-drilled hole 322 are arranged in 42 inner wall of second gear portion and the bias piece 5 Between rolling member 6, and take shape in the groove 421 of at least a pair of opposing on 42 inner wall of second gear portion；Pass through The variation of link position, realizes the blocking rotation of the motor valve between the rolling member 6 and the second gear portion 42.

The working principle of above-mentioned Anti-blocking structure are as follows: during closing valve, kinetic energy is passed to the gear by the motor 8 4, the rotation of gear 4 drives the screw rod 3 to rotate, and the screw rod 3 just drives the stud set component 2 to move upwards, until Valve is closed, for the gear 4 when driving the screw rod 3 rotation, the groove 421 that the rolling member 8 is located at the gear 4 is close One end of 4 inner wall of gear, at this point, the rolling member 8 and the bias piece 5 cooperation are equivalent to an axis, in the gear 4 When rotation, one end that the rolling member 8 withstands on the groove 421 is rotated with the gear 4, is turned so that the screw rod 3 is also synchronous Dynamic, when stud set component 2 closes valve, the stud set component 2 moves to the limit, and at this moment, the motor 8 transmits kinetic energy To the gear 4, the gear 4 is rotated, and since stud set component 2 can not remain in operation, then the screw rod 3 can not also be transported Turn, the rolling member 8 on the screw rod 3 just skids in the gear 4 of rotation；Above structure is simple, easy to assembly, and It can effectively avoid that stall occurs.

Further, the open end in the second gear portion 42, which is provided with, is fixed by clamping structure with the gear 4, is used for The gear cap 9 for preventing the screw rod 3 from deviating from；Specifically, the clamping structure includes taking shape in 42 outer wall of second gear portion Annular groove 422, and take shape in the ring convex of the gear cap 9；Above structure is that the screw rod 3 is being worked or transported in order to prevent During deviate from from the gear 4, influence the normal operation of the motor valve；In addition, the clamping structure can be firm The gear cap 9 is fixed on the gear 4, and is operated conveniently, is not easily disconnected from.

Obviously, the above embodiments are merely examples for clarifying the description, and does not limit the embodiments.It is right For those of ordinary skill in the art, can also make on the basis of the above description it is other it is various forms of variation or It changes.There is no necessity and possibility to exhaust all the enbodiments.And it is extended from this it is obvious variation or It changes still within the protection scope of the invention.
