The direct push of the push rod will affect the net passage size of the original design, and it is difficult to install and upgrade the equipment with high requirements for passage size. Although the direct drive of the hinge shaft will not affect the passage size, the original hinge needs to be modified and upgraded. The hinge is an important component of door protection equipment. It is difficult to improve and upgrade the hinge and the construction period is long. The two common methods of opening doors have some problems in operation when upgrading the existing protective equipment.

[0003] Therefore, how to develop a door opening mechanism that can ensure the original design passage size remains unchanged while being easy to operate and simple to construct is one of the problems that need to be solved urgently. Utility Model Content

[0027] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1 and Figure 2 The present embodiment provides a door opener for a large-load swing door, which mainly includes a connecting seat 1, a hinge seat 2, a motor 3, a swing arm 4 and a connecting rod 5.

[0029] like Figure 3 As shown, the swing door mainly includes a door frame a1 and a door leaf a2; the door frame a1 and the door leaf a2 are connected via a hinge a3, so that the door leaf a2 can rotate relative to the door frame a1 around the hinge a3 to realize the opening and closing of the door leaf a2.

[0030] The connecting seat 1 is used to be installed on the door frame a1;

[0031] The hinge seat 2 is used to be installed on the door leaf a2, and the door leaf a2 is hinged to the door frame a1 via the hinge a3;

[0032] The motor 3, preferably a reduction motor, is fixedly mounted on the connecting seat 1. The output shaft 31 of the motor 3 is connected to a transmission shaft 32, and the transmission shaft 32 is not on the same axis as the central axis of the hinge a3. The motor 3 drives the transmission shaft 32 to rotate during operation.

[0033] Since the motor body needs to be fixed, and the transmission shaft 32 needs to rotate, in order to take both installations into account, Figure 1 and Figure 2 As shown, the connection seat 1 includes a first connection portion 11 and a second connection portion 12 that are spaced apart, the motor 3 is fixedly connected to the first connection portion 11 , and the transmission shaft 32 is rotatably connected to the second connection portion 12 .

[0034] In order to make the transmission shaft 32 rotate more smoothly, a bearing 7 is provided between the transmission shaft 32 and the second connecting portion 12 , and the bearing 7 is preferably a ball bearing.

[0035] In order to prevent dust in the air from entering the bearing 7 and reducing its service life, the second connection portion 12 is located on the upper side and / or lower side bearing cover of the bearing 7. Preferably, a bearing cover 71 is provided on the upper side of the bearing, and a bearing cover 72 is provided on the lower side. Thus, both sides of the bearing 7 are relatively sealed. At the same time, the bearing cover 71 and the bearing cover 72 are respectively connected to the second connection portion 12 by bolts to achieve fixation.

[0036] The output shaft 31 of the motor 3 is connected to the transmission shaft 32 via a coupling 6. The coupling 6 includes an upper coupling 61 and a lower coupling 62, wherein the upper coupling 61 is fixedly connected to the output shaft 31, and the lower coupling 62 is fixedly connected to the transmission shaft 32, thereby achieving the connection between the output shaft 31 and the transmission shaft 32.

[0037] It is worth mentioning that the upper coupling 61 and the lower coupling 62 are both located between the first connecting portion 11 and the second connecting portion 12 .

[0038] The swing arm 4 is fixedly connected to the transmission shaft 32, and the swing arm 4 swings as the transmission shaft 32 rotates;

[0039] One end of the connecting rod 5 is hinged to the end of the swing arm 4 , and the other end is hinged to the hinge seat 2 .

[0040] The swing arm 4 and the connecting rod 5 form a double connecting rod structure, and the swing of the swing arm 4 can drive the door leaf a2 to open and close.

[0041] This solution does not need to destroy the original swing door structure, so it can ensure that the original design passage size remains unchanged. At the same time, the door leaf can be automatically opened and closed by only one motor 3, which has the advantages of simple construction and convenient operation.

[0042] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
