X ray machine spot film system electric door device

Abstract

The invention relates to a spot film system of a X-ray machine, in particular to an electrically operated door device of the spot film system of the X-ray machine, which comprises rocker arms, a spot film door fixed thereon and a motor arranged on a support board; wherein the motor is arranged at one end of the support board and is connected with a first rocker arm of the end via a swing rod; the other end of the support board is provided with a door rotating shaft and an angle positioning device which synchronizes with the door rotating shaft, a second rocker arm of the end is arranged on the door rotating shaft; and torsion springs are arranged on the first and the second rocker arms. The rotation of the motor of the invention is controlled by two travel switch components, the operation is balanced and noiseless, and has no adverse effects on the spot film system; furthermore, the occupying space is small.

Description

technical field [0001] The invention relates to an X-ray machine spotting system, in particular to an electric door device for the X-ray spotting system. Background technique [0002] Digital remote-controlled diagnostic X-ray machines are widely used clinically. The spotting system on it is located at the entrance and exit of the cassette carrier without a spotting door, which is not beautiful and has potential safety hazards; or install a simple blocking device, install Afterwards, it has a great influence on the running stability of the whole spotting system. [0003] At present, the spotting system on the digital remote diagnostic X-ray machine is equipped with a mechanical spotting door at the entrance and exit of the cassette carrier, which is usually integrated with the spotting system, so it is very dependent on the spotting system. Since the force to drive the mechanical spot door comes from the moving parts inside the spot film system, the moving parts are driven ...

AI Technical Summary

Problems solved by technology

Since the force to drive the mechanical spot door comes from the moving parts inside the spot film system, the moving parts are driven by the motor through the belt, and when the force is applied to the mechanical spot film door by the push rod, the push rod hits the spot film door The rocker arm will open the film door, so there will be metal impact noise; when the film door is to be closed, the moving parts will move in the opposite direction driven by the motor through the belt, and the film door will be closed under the action of the torsion spring , which produces noise

In addition, when the moving part applies force to the spot film gate, it also receives the reaction force of the spot film gate correspondingly. This reaction force produces a reverse torque to the motor driving the moving part, causing the entire spot film system to The motion performance is affected. If the reaction force is too large, it will also lead to overload protection of the electrical control, stop the moving parts, and affect the realization of the internal functions of the dot film system, so that the normal filming function cannot be realized, which greatly reduces the system. operational reliability

Since the mechanical spotting door is highly dependent on the movement of the entire spotting system, it is necessary to undergo cumbersome debugging during the installation process, and the installation is time-consuming and laborious.

[0004] In addition, the X-ray machine has a small space and a complex structure, and the movement trajectory of the spot film door will be limited by the structure of the machine itself.

If the output shaft of the motor is directly engaged with the rotating shaft of the dot film door through a coupling, in this case, if the motor is powered off or damaged, the motor cannot run normally, and the door cannot be opened freely
