[0041] See also Figure 1 and Figure 2 Now, the swing gate mechanism provided in the embodiment of the present application is described. The swing gate mechanism comprises:

[0042] A rotating rod 1 having a first end and a second end;

[0043] A first abutting structure 3, connected to the first end;

[0044] The second abutment structure 4 is connected to the second end, and at least one of the first abutment structure 3 and the second abutment structure 4 is detachably connected to the rotating rod 1;

[0045] The swing arm 2 has one end abutting against the first abutting structure 3 , and the other end abutting against the second abutting structure 4 .

[0046] The rotating rod 1 is rotatably disposed on the gate 10 and connected to the driving mechanism 6. The driving mechanism 6 drives the rotating rod 1 to rotate, so as to drive the swing arm 2 to swing, thereby realizing the opening and closing of the gate 10. The rotating rod 1 can be made of metal, plastic and other materials, among which aluminum alloy is preferred, and aluminum alloy has light weight and high strength; the swing arm 2 can also be made of metal, plastic and other materials, among which acrylic plate is preferred, which is more beautiful and has high impact resistance and is not easy to break.

[0047] In this embodiment, the first abutment structure 3 and the second abutment structure 4 are respectively arranged at the first end and the second end of the rotating rod 1, and the first end and the second end are respectively the two ends of the rotating rod 1, and the two ends of the swing arm 2 are respectively abutted against the first abutment structure 3 and the second abutment structure 4, and the swing arm 2 is fixed by the abutment of the two ends. In order to realize the installation of the swing arm 2, at least one of the first abutment structure 3 and the second abutment structure 4 is detachably connected to the rotating rod 1. Specifically, the first abutment structure 3 or the second abutment structure 4 can be detachably connected to the rotating rod 1, or both the first abutment structure 3 and the second abutment structure 4 can be detachably connected to the rotating rod 1. The detachable connection method here can be a connection method such as plug-in, bolt connection, and threaded connection. Taking the example that the first abutment structure 3 is detachably connected to the rotating rod 1 and the second abutment structure 4 is fixedly connected to the rotating rod 1, when installing the swing arm 2, one end of the swing arm 2 can be first abutted against the second abutment structure 4, and the swing arm 2 is in the correct installation position, and then the first abutment structure 3 is connected to the rotating rod 1, so that the first abutment structure 3 abuts against the other end of the swing arm 2, thereby realizing the installation of the swing arm 2.

[0048] In the present embodiment, the first abutting structure 3 and the second abutting structure 4 are respectively abutted against the two ends of the swing arm 2 to fix the swing arm 2. There is no need to weld a fixing plate on the rotating rod 1, nor is there any need to drill a hole on the swing arm 2. The fixing plate is connected to the swing arm 2 by bolts. This can greatly reduce the difficulty of installing the swing arm 2, is beneficial to the processing and manufacturing of the swing gate mechanism, and reduces the dependence on professional technicians such as welding workers.

[0049] See also Figure 1 , Figure 2 Right now Figure 3 In one embodiment of the present application, a long hole 11 is provided along the axial direction of the rotating rod 1, and a first abutting structure 3 and a second abutting structure 4 are respectively located at two ends of the long hole 11. The swing arm 2 has a first side portion for connecting the rotating rod 1, and the first side portion is inserted into the long hole 11. One end of the first side portion abuts against the first abutting structure 3, and the other end of the first side portion abuts against the second abutting structure 4.

[0050] In most cases, the swing arm 2 is connected to the rotating rod 1 through one side thereof, and the side of the swing arm 2 can be located outside the rotating rod 1, and the first abutting structure 3 and the second abutting structure 4 abut the two ends of the side of the swing arm 2, but this method has poor installation stability of the swing arm 2 and is not beautiful. In this embodiment, the first abutting structure 3, the second abutting structure 4 and the long hole 11 are arranged along the axial direction of the rotating rod 1, that is, the long hole 11 extends along the length direction of the rotating rod 1, and the first side of the swing arm 2 is inserted into the long hole 11, one end abuts against the first abutting structure 3, and the other end abuts against the second abutting structure 4. The connecting part of the swing arm 2 and the first abutting structure 3 and the second abutting structure 4 can be shielded by the rotating rod 1, so that the aesthetics can be greatly improved. In addition, the first side of the swing arm 2 is inserted into the long hole 11 of the rotating rod 1, and the long hole 11 can stabilize the swing arm 2 to a certain extent, so that the stability of the installation of the swing arm 2 can be improved.

[0051] See also Figures 3 to 10 In one embodiment of the present application, a first groove body 12 and a second groove body 13 are respectively provided at both ends of the rotating rod 1 corresponding to the long hole 11, one end of the first side portion is inserted into the first groove body 12, and the other end of the first side portion is inserted into the second groove body 13, and the portion of the rotating rod 1 located between the first groove body 12 and the second groove body 13 is a hollow structure.

[0052] The rotating rod 1 can adopt a hollow structure or a solid structure, wherein the hollow structure can reduce the weight of the swing gate and help drive it, but the rotating rod 1 with a hollow structure has a relatively poor fixing effect on the swing arm 2. In this embodiment, the rotating rod 1 is respectively provided with a first slot body 12 and a second slot body 13 at both ends corresponding to the long hole 11, and the two ends of the first side portion of the swing arm 2 are respectively inserted into the first slot body 12 and the second slot body 13, and the swing arm 2 is fixed at both ends. When the rotating rod 1 drives the swing arm 2 to rotate, the inner walls of the first slot body 12 and the second slot body 13 can apply a force to the swing arm 2. Compared with the hollow structure, the contact area between the swing arm 2 and the rotating rod 1 can be greatly increased, thereby increasing the stability of the swing arm 2. The part of the rotating rod 1 located between the first slot body 12 and the second slot body 13 is a hollow structure, which can effectively reduce the overall weight of the rotating rod 1.

[0053] See also Figures 4 to 11 In one embodiment of the present application, a first plug-in portion 21 is provided at the end portion of the swing arm 2 abutting against the first abutting structure 3, a second plug-in portion 31 is provided at the position where the first abutting structure 3 abuts against the swing arm 2, the first plug-in portion 21 and the second plug-in portion 31 are plugged into each other, a third plug-in portion 22 is provided at the end portion of the swing arm 2 abutting against the second abutting structure 4, a fourth plug-in portion 41 is provided at the position where the second abutting structure 4 abuts against the swing arm 2; the third plug-in portion 22 and the fourth plug-in portion 41 are plugged into each other.

[0054] The fixing of the swing arm 2 mainly relies on the two ends of the swing arm 2 abutting against the first abutting structure 3 and the second abutting structure 4. In this embodiment, a first plug-in portion 21 is provided at the end of the swing arm 2 abutting against the first abutting structure 3, a second plug-in portion 31 is provided at the position where the first abutting structure 3 abuts against the swing arm 2, a third plug-in portion 22 is provided at the end of the swing arm 2 abutting against the second abutting structure 4, and a fourth plug-in portion 41 is provided at the position where the second abutting structure 4 abuts against the swing arm 2. By plugging the first plug-in portion 21 with the second plug-in portion 31 and the third plug-in portion 22 with the fourth plug-in portion 41, the stability of the connection between the swing arm 2 and the rotating rod 1 can be effectively improved, especially the stability in the radial direction of the rotating rod 1.

[0055] Each mating plug-in portion can be plugged in by mating a groove and a protrusion, for example Figure 4-Figure 6 As shown, the first plug-in portion 21 and the third plug-in portion 22 at both ends of the swing arm 2 are groove structures, the second plug-in portion 31 on the first abutting structure 3 and the fourth plug-in portion 41 on the second abutting structure 4 are both convex structures, and the second plug-in portion 31 and the fourth plug-in portion 41 are respectively inserted into the first plug-in portion 21 and the third plug-in portion 22 at both ends of the swing arm 2 to further fix the swing arm 2; for another example, the first plug-in portion 21 and the third plug-in portion 22 at both ends of the swing arm 2 may be convex structures, the second plug-in portion 31 on the first abutting structure 3 and the fourth plug-in portion 41 on the second abutting structure 4 may be both groove structures, and the first plug-in portion 21 and the third plug-in portion 22 at both ends of the swing arm 2 may be respectively inserted into the second plug-in portion 31 and the fourth plug-in portion 41 to further fix the swing arm 2; in addition, the first plug-in portion 21 and the third plug-in portion 22 at both ends of the swing arm 2 may be groove structures and convex structures, respectively, and the second plug-in portion 31 and the fourth plug-in portion 41 are respectively arranged correspondingly.

[0056] See also Figure 2 , Fig.12 , Fig.14 and Fig.15 In one embodiment of the present application, the first abutment structure 3 is inserted into the first end of the rotating rod 1, and the first abutment structure 3 is key-connected to the rotating rod 1. The first abutment structure 3 is provided with a driving connection portion 32 for connecting the driving mechanism 6, and the driving connection portion 32 is located at the end of the first abutment structure 3 away from the swing arm 2.

[0057] In the previous embodiments, at least one of the first abutment structure 3 and the second abutment structure 4 is detachably connected to the rotating rod 1. In the present embodiment, the first abutment structure 3 is inserted into the first end of the rotating rod 1, that is, the first abutment structure 3 is detachably connected to the rotating rod 1.

Fig.14 As shown, when the first abutment structure 3 is connected to the driving mechanism 6, the position of the first abutment structure 3 is fixed. At this time, the first abutment structure 3 is inserted into the first end of the rotating rod 1, so that the first abutment structure 3 can maintain the state of abutting the swing arm 2, thereby achieving the fixation of the swing arm 2. When the first abutment structure 3 is inserted into the rotating rod 1, the first abutment structure 3 is key-connected with the rotating rod 1 so that the first abutment structure 3 can drive the rotating rod 1 to rotate. The key connection between the first abutment structure 3 and the rotating rod 1 can be a single key, a rectangular key, a spline, etc., as shown in FIG. Figure 2 In the embodiment shown, a cross spline connection is adopted.

[0059] The driving connection part 32 is used to connect with the driving mechanism 6, and can be connected by key connection, clamping connection, etc. Fig.15 In the illustrated embodiment, the driving connection portion 32 is a semicircular clamp structure, which is connected to the other half of the connection structure to clamp the output shaft of the driving mechanism 6, and the mechanical transmission is ensured by a key.
