[0041] Please refer to Figures 1 to 3 , an embodiment of the present utility model provides a rotary connection structure, which is connected between a first rotary body 10 and a second rotary body 20 and is used to realize the rotary connection of the two rotary bodies; the rotary connection structure includes an intermediate connection seat 32, the first end of the intermediate connection seat 32 is fixedly connected to the second rotary body 20, and the second end is rotatably connected to the first rotary body.

[0042] Specifically, a first hook portion 321 is provided at the first end of the intermediate connection seat 32, and a rotating shaft member 33 is provided at the second end of the intermediate connection seat 32;

[0043] The rotary connection structure further includes:

[0044] A raised seat 35 provided on the first rotary body, a second shaft hole 351 is provided on the raised seat 35, and the rotating shaft member 33 is rotatably inserted into the second shaft hole 351;

[0045] A spring piece limiting member 31 provided on the second rotary body, and the first hook portion 321 is snap-fitted with the spring piece limiting member 31.

[0046] The connection and rotation between the second rotating body 20 and the first rotating body are realized through the intermediate connecting seat 32, ensuring that the second rotating body 20 can rotate relative to the first rotating body 10, making the rotational movement between the rotating bodies smoother, and improving the flexibility and operability between the rotating bodies.

[0047] In practical applications, taking the gate at the entrance and exit of a parking lot as an example, the first rotating body 10 can be two parallel rods up and down in the gate. These two parallel rods will rotate and lift when the gate is opened. The convex seat 35 is located on the two parallel rods. The second shaft hole 351 on the convex seat 35 cooperates with the rotating shaft member 33 at the second end of the intermediate connecting seat 32, enabling the first rotating body 10 to rotate around the rotating shaft member 33. When the gate needs to be opened or closed, the first rotating body 10 makes corresponding rotational movements centered on this connection point to change its angle with the ground, thereby controlling the passage or blocking of vehicles.

[0048] The second rotating body 20 can be the originally juxtaposed shift rods in the middle. During the operation of the gate, although these shift rods remain vertical, they change from being spaced apart to being closely attached to each other; since the first end of the intermediate connecting seat 32 is fixedly connected to the second rotating body 20, the first hook portion 321 thereon is snap-fitted with the elastic piece limiting member 31 on the second rotating body to ensure the stability of the connection. When the first rotating body 10 rotates, through the connection relationship between the intermediate connecting seat 32 and the second rotating body, the second rotating body 20 is driven to act in coordination. For example, during the opening process of the gate, as the first rotating body 10 rotates and lifts, the second rotating body 20 remains vertical, that is, it rotates relative to the two parallel rods and changes from the spaced state to the closely attached state.

[0049] It can be understood that the application of the rotational connection structure in this embodiment in the gate at the entrance and exit of a parking lot enables each part of the gate to act coordinately and orderly, meets the actual requirements of the parking lot for vehicle access management, and improves the reliability and operability of the gate.

[0050] Please refer to Figure 4 、 Figure 5 In this embodiment, the two ends of the second rotating body 20 are provided with hollow cavities. The first end of the intermediate connecting seat 32 is provided with a plugging portion that can be detachably inserted into the hollow cavity. The cavity wall of the hollow cavity is provided with an elastic piece limiting member 31, and the intermediate connecting seat 32 is provided with a first hook portion 321. The two are tightly snap-fitted to firmly fix the intermediate connecting seat 32 in the second rotating body 20.

[0051] Specifically, the first hook portion 321 is a convex strip-shaped structure; the elastic piece limiting member 31 is a double-inclined elastic piece limiting structure composed of two opposite and inclined elastic pieces.

[0052] The quick connection and fixation of the intermediate connecting seat 32 and the second rotating body 20 are realized by the cooperation of elastic clamping and a clamping hook, which is conducive to making the installation and disassembly more convenient and fast, and improving the production and maintenance efficiency.

[0053] In this embodiment, a first shaft hole 322 is provided at the second end of the intermediate connecting seat 32, and a positioning groove 324 for positioning the raised seat 35 is provided on the intermediate adapter seat 32; a second shaft hole 351 is provided on the raised seat 35, and the rotating shaft member 33 passes through the first shaft hole 322 and the second shaft hole 351, and the first shaft hole 322 and the second shaft hole 351 are rotationally connected through the rotating shaft member 33. The intermediate connecting seat 32 and the first rotating body are connected by the rotating shaft member 33 to realize the rotating function, so that the second rotating body 20 can rotate smoothly, enhancing the flexibility and adaptability between the rotating bodies and meeting the rotating requirements at different angles.

[0054] Please refer to Figure 6 , in this embodiment, a second clamping hook portion 331 is provided at one end of the rotating shaft member 33, and a stepped structure 323 is provided on the inner wall of the first shaft hole 322. The two are clamped to limit the rotating shaft member 33 in the first shaft hole 322; a clamping hook limiting member 3231 is provided on the stepped structure 323, and the second clamping hook portion 331 is limited in the clamping hook limiting member 3231. The clamping hook limiting member 3231 is used to prevent the rotating shaft member 33 from rotating relative to the intermediate connecting seat 32. An annular enclosure 332 is provided at the end of the rotating shaft member 33 away from the second clamping hook portion 331, and the annular enclosure 332 abuts against the edge of the first shaft hole 322.

[0055] It can be understood that the clamping hook limiting member 3231 is in the shape of a limiting groove, and the limiting groove can be formed by two adjacent convex blocks or by a convex block with a groove; in addition, a plurality of clamping hook limiting members 3231 can be provided, so that when the rotating shaft member 33 is inserted into the intermediate connecting seat 32 at any angle, the limiting in the clamping hook limiting member 3231 can be quickly realized.

[0056] It can be understood that on the basis of the foregoing structure, the rotating shaft member 33 is limited in the first shaft hole 322 of the intermediate connecting seat 32 by the clamping hook and stepped clamping method, preventing the rotating shaft member 33 from falling off, ensuring the stability of the rotating shaft member 33, and making the rotating motion more reliable.

[0057] Please refer to Figure 7, Further, the movable connection component further includes a rotating shaft cover 34. The front end of the rotating shaft cover 34 is inserted into the rotating shaft member 33. The front end of the rotating shaft cover 34 is provided with a third hook portion 341, and the outer wall of the rotating shaft member 33 is provided with a groove-shaped clamping portion 333. The two are clamped. When the rotating shaft cover 34 is clamped to the rotating shaft member 33, the second hook portion 331 on the rotating shaft member 33 will be stably clamped to the step structure 323. Therefore, the second hook portion 331 will not rebound, so that the rotating shaft member 33 is stably held in the first shaft hole 322. When replacing parts, first pull out the rotating shaft cover 34. At this time, the second hook portion 331 on the rotating shaft member 33 can rebound inward, and then the rotating shaft member 33 can be taken out. The rotating shaft member 33 is further fixed by the rotating shaft cover 34 to prevent the rotating shaft member 33 from loosening, improving the connection stability of the rotating shaft member 33 and further enhancing the overall reliability between the rotating bodies.

[0058] The rotating shaft member 33 is a hollow structure. The hollow structure can reduce the weight, lower the material cost, and also make the rotation action of the second rotating body 20 light and smooth.

[0059] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of the present application, the patent protection scope of the present application cannot be limited thereby. Any technical solution obtained by equivalent structure or equivalent process substitution or modification based on the substantial concept of the present application and using the content recorded in the text and drawings of the specification of the present application, as well as any technical solution directly or indirectly implementing the above embodiments in other related technical fields, etc., are all included in the patent protection scope of the present application.
