[0002] In the field of opening and closing driving devices of various door bodies, the traditional door opening structure often has some deficiencies. For example, the structure design of part of the device is not compact and reasonable enough, resulting in a large occupied space, which is limited in some space-limited places. At the same time, the durability and reliability of the traditional device need to be improved. Since there is no effective dustproof measure, dust and impurities can easily enter the interior of the device, causing wear and tear to the key components and affecting the service life of the device. In addition, the stability of the transmission component is often ignored. If the radial force and axial force suffered by the transmission screw during rotation cannot be effectively supported, the rotation posture of the screw will be unstable, which not only affects the transmission efficiency, but also may cause shaking and noise during device operation, reducing user experience. Therefore, it has important practical significance to develop a door body driving device with compact structure, high durability and stable transmission. SUMMARY

[0006] The transmission shaft of the drive motor and the transmission screw are located at the same axial position, and are transmissionally matched through a shaft coupling; the transmission nut is nested on the transmission screw, and a connecting seat for connecting with the door body is arranged on the transmission nut;

[0007] The outer shell is nested on the push rod module, and a hinge seat is arranged at the front end of the outer shell; the outer shell is formed with an outer shell slot corresponding to the stroke length of the transmission screw, and the connecting seat arranged on the transmission nut is arranged to pass through the outer shell slot.

[0008] As a further scheme of the utility model: a dust strip is arranged on the outer shell slot along the length direction thereof.

[0009] As a further scheme of the utility model: a set of support bearings is arranged at each end of the transmission screw, and the support bearings are fixedly connected with the outer shell.

[0010] The utility model discloses beneficial effect: in the practical application scene of door body opening and closing, this device shows many excellent characteristics. Its overall structure design is compact, and each component structure cooperation is accurate and stable, greatly reduces the space occupation, still makes the overall structure more regular, orderly, effectively avoids the space waste problem caused by the complicated components, especially suitable for all kinds of space limited place.

[0015] In the embodiments of the utility model, unless otherwise specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or it can be integrated; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium; it can be the communication or interaction relationship between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0016] Please refer to Figs. 1-2 In the embodiments of the utility model, a novel linear door opener push rod structure comprises: a shell body 1 and a push rod module.

[0017] The push rod module comprises: a driving motor 5, a transmission screw 7 and a transmission nut 8.

[0018] The transmission shaft of the driving motor 5 is located in the same axial position as the transmission screw 7, and is in transmission cooperation through the shaft coupling 6; the transmission nut 8 is nested on the transmission screw 7, and the transmission nut 8 is moved on the transmission screw 7 by rotating the transmission screw 7 driven by the driving motor 5, and the connecting seat 3 for connecting with the door body is arranged on the transmission nut 8;

[0019] The outer shell 1 is nested on the push rod module, and the front end (motor end) of the outer shell 1 is provided with a hinged seat 2; the outer shell 1 is formed with an outer shell slot corresponding to the stroke length of the transmission screw 7, and the connecting seat 3 arranged on the transmission nut 8 is arranged to pass out of the outer shell slot.

[0020] When in use, the push rod module is fixed on the wall body through the hinged seat 2, and the connecting seat 3 is connected with the door body, and the driving motor 5 drives the transmission nut 8 to move, so that the door body rotates along the hinge point, realizing the effect of opening and closing the door.
