[0033] The following will combine the drawings and specifically describe the utility model.Figure 1 To be continued Figure 5 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0034] It should be noted that, in the embodiments of this utility model, the directions shown in the accompanying drawings shall prevail, such as front and back.

Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.

[0035] Reference Figures 1-5 As shown, this utility model provides a transmission mechanism for an anti-pinch intelligent access control gate, including a gate body 1, a transmission mechanism 2 and a drive mechanism 3, wherein the transmission mechanism 2 and the drive mechanism 3 are both installed inside the gate body 1;

[0036] The gate body 1 is equipped with a limit plate 12 and a controller 11, with the controller 11 located on both sides of the transmission mechanism 2;

[0037] The transmission mechanism 2 includes a gate plate 1 21, a gate plate 22, and a gate plate 3 23 from the outside to the inside. The gate plate 1 21 has arc-shaped guide grooves 212 on both sides, and springs 24 are installed inside the arc-shaped guide grooves 212. Connecting shafts 214 are fixedly connected to the lower sides of the gate plate 1 21, and the connecting shafts 214 pass through the controller 11. Insertion shafts 222 are fixedly connected to the lower sides of the gate plate 22, and the insertion shafts 222 pass through the connecting shafts 214.

[0038] The drive mechanism 3 includes an electric hydraulic cylinder 31, a rack 33 and a rack 34. The output end of the electric hydraulic cylinder 31 is fixedly connected to a connecting plate 32, and the rack 33 and rack 34 are both fixedly connected below the connecting plate 32.

[0039] The limit plate 12 is the controller of the gate in the prior art, used to control the operation of the electric hydraulic cylinder 31; the controller 11 also has an arc-shaped guide groove 212, and there is a spring 24 inside the arc-shaped guide groove 212. The spring 24 is used to push the gate plate 21 to always expand outward, so as to prevent the gate plate 21 from resetting when the rack 33 is not engaged with the gear 215. The arc-shaped guide groove 212 has a limit slider 213 inside, which is fixedly connected to both sides of the gate plate 21 and is mainly used to limit the controller 11 to rotate thirty degrees.

[0040] In a further embodiment, the connecting shaft 214 is fixedly connected with a gear one 215 at one end outside the controller 11, and the gear one 215 cooperates with the rack one 33.

[0041] In this embodiment, the rack one 33 meshes with the gear one 215 to enable the shutter one 21 to rotate by thirty degrees, and the rack two 34 meshes with the gear two 223 when they are not meshed, and in this process, the shutter one 21 rotates with the shutter two 22 and the shutter three 23 due to the rack two 34 not meshing with the gear two 223.

[0042] In a further embodiment, the plug-in shaft 222 is fixedly connected with the gear two 223 at one end outside the connecting shaft 214, and the gear two 223 cooperates with the rack two 34.

[0043] In this embodiment, the plug-in shaft 222 is coaxial with the connecting shaft 214, but only the gear one 215 and the gear two 223 near one end of the driving mechanism 3 are installed on the two sides of the shutter one 21 and the shutter two 22.

[0044] In a further embodiment, the shutter two 22 is fixedly connected with a limiting sliding block two 224 on both sides, and the limiting sliding block two 224 is slidingly connected inside the arc-shaped guide groove 212 and located on one side of the spring 24.

[0045] In this embodiment, the spring 24 always pushes the shutter one 21 to move inside the embedded groove one 211, and the arc-shaped guide groove 212 is used to limit the rotation range of the shutter two 22, so that when the shutter three 23 above is subjected to a downward force, it can be transmitted to the spring 24 through the shutter two 22 and the limiting sliding block two 224 for absorption.

[0046] In a further embodiment, the shutter three 23 is fixedly connected with a rotating shaft 231 and a protrusion 232 on both sides, and the shutter two 22 is provided with a limiting sliding groove 225, and the protrusion 232 is located inside the limiting sliding groove 225.

[0047] In this embodiment, the limiting sliding groove 225 enables the protrusion 232 to be passively moved after the shutter two 22 rotates, so that the shutter three 23 is forced to rotate by seventy degrees around the rotating shaft 231.

[0048] In a further embodiment, the shutter one 21 is provided with an embedded groove one 211 inside, and the shutter two 22 is provided with an embedded groove two 221 inside.

[0049] In this embodiment, the embedded groove one 211 and the embedded groove two 221 enable the shutter one 21, the shutter two 22, and the shutter three 23 to be accommodated from the outside to the inside.

[0050] In further embodiments, the second shutter 22 and the third shutter 23 are rotatably connected to the inside of the embedding groove one 211 through the insertion shaft 222 and the rotating shaft 231 respectively, and part of the third shutter 23 is located in the inside of the embedding groove two 221.

[0051] In the embodiments, the second shutter 22 has an opening at the rotating shaft 231, so that the third shutter 23 can rotate through the rotating shaft 231, and part of the third shutter 23 is located in the inside of the embedding groove two 221.

[0052] The working principle of the utility model is as follows:

[0053] When the electric hydraulic cylinder 31 operates to make the connecting plate 32, the rack one 33 and the rack two 34 move upwards, the rack one 33 will first make the whole first shutter 21, the second shutter 22 and the third shutter 23 rotate thirty degrees around the connecting shaft 214 through the gear one 215, at this time, the rack one 33 will no longer engage with the gear one 215, but will make the rack two 34 engage with the gear two 223, thereby making the second shutter 22 rotate thirty degrees, and making the second shutter 22 unfold from the inside of the embedding groove one 211, and in the unfolding process, the convex block 232 is limited by the limiting sliding groove 225, so that the third shutter 23 is forced to rotate seventy degrees around the rotating shaft 231, thereby unfolding upwards, thereby expanding the blocking range of the access control baffle, thereby avoiding passing from above;

[0054] And if still want to pass above the baffle, the third shutter 23 is pressed down when passing, which will force the second shutter 22 to rotate again, at this time, the limiting sliding block two 224 will press the spring 24, thereby avoiding being clamped when the third shutter 23 is flipped or pressed down, thereby protecting the user.

[0055] According to the disclosure and teaching of the above description, the skilled in the art of the utility model can also change and modify the above embodiments. Therefore, the utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes of the utility model should fall within the protection scope of the claims of the utility model. In addition, although some specific terms are used in the specification, these terms are only for convenience of explanation, and do not constitute any limitation on the utility model.
