Technical Field

The utility model relates to the technical field of assembling equipment, in particular to a T-shaped shaft assembling mechanism capable of serving as an industrial Internet of things manufacturing perception control layer.

Background

In the existing intelligent gas meter, taking an IC card intelligent gas meter as an example, an electromechanical valve adopted therein has three structures:

the electromechanical valve rotates forward and backward through the motor, the gear drives the worm, and meanwhile, the push rod moves in the spiral groove of the worm, so that the opening and closing of the valve are realized. The electromechanical valve of this kind is characterized by no unloading device, and the locked rotor can be obtained after the forward rotation and the backward rotation are in place, and the load is also larger, thus causing large current of the control circuit and large power consumption. And the reliability of a control circuit of the main controller valve can be influenced, the service life of a battery in the controller is shortened, the energy storage capacitance value adopted for closing the valve is very large, and the valve is closed under positive pressure and is unreliable.

The electromechanical valve drives the sector gear to rotate by the forward and reverse rotation of the motor, so that the functions of anti-rotation blockage and quick closing are achieved. The gear speed changing box is characterized in that an anti-rotation-blocking mechanism consisting of a swinging plate and a swinging gear above the swinging plate is meshed with a sector gear, and the swinging gear fixed above the swinging plate is meshed with the sector gear to realize the anti-rotation-blocking function of the electromechanical valve by matching with the swinging of the swinging plate. The electromechanical valve of this kind is characterized in that the oscillating plate and the structure of the oscillating gear fixed above the oscillating plate and the sector gear which are meshed with each other cannot realize complete forward and reverse unloading.

The electromechanical valve rotates forwards and backwards through the motor, incomplete teeth rotate, and the functions of preventing rotation blockage and quickly closing are achieved. The further structural characteristics are that the ratchet double-connection gear is installed, and complete unloading can be realized in forward rotation and reverse rotation of the motor by matching with locking and unlocking of the incomplete gear and the locking block. The electromechanical valve is characterized in that because the valve core of the electromechanical valve is arranged in the shell, enough space must be reserved between the valve core and the shell, airflow can smoothly pass through the electromechanical valve, and the electromechanical valve cannot influence the meter clamping performance due to overlarge pressure loss, so that the integral volume of the electromechanical valve is large and the electromechanical valve cannot be arranged in an aluminum shell gas meter.

Based on the structure and characteristics of the electromechanical valve of the prior art, the applicant previously proposed a gas meter electromechanical valve solution as described in application No. CN 201220463732.0.
