Description

Technical Field

[0001] This utility model relates to the field of trackless telescopic gates, specifically to a rotating connection structure for the motor head of a trackless telescopic gate. Background Technology

[0002] Trackless sliding gates, as a common automated access control device in modern buildings, have the advantages of easy operation, high space utilization, and beautiful appearance. One of its core components is the rotating connection structure of the motor head, which plays a crucial role in the stability, durability, and smooth operation of the gate. The rotating connection structure usually uses bearings and transmission devices to ensure the stability and accuracy of the gate during rotation.

[0003] According to the published patent CN210033238U, a toothed connection device for a telescopic gate motor head and gate body, it includes a gate panel, a gate panel connecting crossbar, a gate head, a gate head connecting crossbar, and a toothed connection assembly. The gate panel connecting crossbar is arranged vertically and parallel on the gate panel, and the gate head connecting crossbar is fixedly arranged vertically and parallel on the gate head. The gate panel connecting crossbar and the gate head connecting crossbar are fixedly connected by the toothed connection assembly. The toothed connection assembly includes a first connector, a second connector, and a limiting pin. The first connector includes a first fixing rod, a first positioning hole, a toothed groove, and a first hook. The second connector includes a second fixing rod, a second positioning hole, a protruding tooth, and a second hook. This anti-collision post with inverted stabilizing fasteners has a simple structure. By using inverted stabilizing fasteners formed at both ends of the post and the inner port of the outer cylinder, it can effectively solve the problems of dust and sand ingress, pressure resistance, and friction, thereby improving the overall service life of the anti-collision post and facilitating its widespread promotion and use.

[0004] However, in traditional trackless retractable gates, if a rotating connection is used to connect the motor head to a large gate body, the gate is prone to swaying or shifting when encountering external forces such as wind, affecting its stability. Furthermore, the extension distance of a trackless retractable gate is fixed during use, leading to situations where the gate, even when fully extended, cannot cover the required distance. In such cases, the entire trackless retractable gate usually needs to be replaced, which is not only cumbersome but also costly, significantly reducing its flexibility and ease of use. Therefore, a new technical solution is needed to address this issue. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to practical needs, and provide a rotating connection structure for the motor head of a trackless telescopic gate. This solves the problem that in traditional trackless telescopic gates, if a rotating connection method is used to connect the motor head to a large-sized gate body, the gate body is prone to swaying or shifting when encountering external forces such as wind, affecting the stability of the gate body. Moreover, the telescopic distance of a trackless telescopic gate is fixed during use, which leads to situations where the gate body cannot meet the required coverage distance even when fully extended. Once this happens, it usually requires the staff to replace the entire trackless telescopic gate, which is not only cumbersome but also costly, greatly reducing the flexibility and ease of use of trackless telescopic gates.

[0006] To achieve the purpose of this utility model, the technical solution adopted by this utility model is as follows: a rotating connection structure for a trackless telescopic gate motor head is designed, including a motor head body, a control host is embedded in the top front end of the motor head body, a telescopic gate body is provided on the side of the motor head body, multiple rotating wheels are installed at the bottom of both the motor head body and the telescopic gate body, and a rotating connection component is provided between the telescopic gate body and the motor head body.

[0007] Preferably, the rotary connection assembly includes an L-shaped plate, a fixed column, a sleeve, a bearing, a first connecting rod, a rotating shaft, a second connecting rod, a groove, a fixed rod, a rotating cylinder, a limiting plate, and a fixing bolt.

[0008] Preferably, a plurality of L-shaped plates are disposed on the side of the machine head body, and a fixing post is fixed between two corresponding L-shaped plates. A sleeve is sleeved on the outside of the fixing post, and a bearing passes through the outside of the sleeve, and the bearing is rotatably connected to the sleeve.

[0009] Preferably, one end of the first connecting rod is fixed to one side of the bearing, and a rotating shaft is fixed to the other end of the first connecting rod. A rotating cylinder is fixed to the end of the rotating shaft away from the first connecting rod. The rotating cylinder is located in a groove opened on the surface of the telescopic gate. A fixed rod passes through the inside of the rotating cylinder, and grooves are fixed at both the upper and lower ends of the fixed rod.

[0010] Preferably, the front and rear ends of the rotating cylinder and the bearing are fitted with limit plates, and the limit plates are provided with fixing bolts on both sides, which are threaded to the threaded grooves on the surface of the rotating cylinder and the bearing.

[0011] Preferably, an electric telescopic cylinder is fixed at the end of the L-shaped plate away from the fixed column, and the electric telescopic cylinder is installed in a circular groove opened on the side of the machine head body.

[0012] Preferably, a plurality of telescopic components are provided between the fixed column and the sleeve. The telescopic components include a first fixed cylinder and a second fixed cylinder that are nested together. A damping block is fixed to one end of the second fixed cylinder located inside the first fixed cylinder, and a spring is fixed to the end of the damping block away from the second fixed cylinder.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. This utility model, through the combination of the machine head body, the door body, and the rotating connecting assembly, not only utilizes multiple bearings, rotating cylinders, and rotating shafts to connect with the first and second connecting rods, increasing the rotation range between the machine head and the door body, thus enabling the machine head body and the door body to complete displacement between them with a large gap, increasing the rotational movement distance, but also, by using the upper and lower double bearings, rotating cylinders, and rotating shafts, increases the stability and strength of the rotating connecting assembly during rotation. Simultaneously, due to the inclusion of a limit plate, the rotation of the rotating connecting assembly can be limited. After the machine head and door body have rotated, the limit plate can limit the rotation of the rotating connecting assembly, preventing the door body from swaying or shifting when encountering external forces such as wind. This solves the technical problem in traditional trackless telescopic gates where, if a rotating connection method is used to connect the machine head to a large-sized door body, the door body is prone to swaying or shifting when encountering external forces such as wind, affecting the stability of the door body.

[0015] 2. This utility model, through the combination of an L-shaped plate, a circular groove, and an electric telescopic cylinder, allows for adjustment of the distance between the gate and the motor head. When the gate, even when fully extended, still cannot meet the required coverage distance, the distance between the motor head and the gate can be extended by one end, ensuring the motor head fully covers the required distance. This solves the problem that the telescopic distance of trackless sliding gates is fixed during use, leading to situations where the gate, even when fully extended, still cannot meet the required coverage distance. In such cases, replacing the entire trackless sliding gate is usually required, which is not only cumbersome but also costly, significantly reducing the flexibility and ease of use of trackless sliding gates.

[0016] 3. This utility model combines a fixed column, a sleeve, and a telescopic component. Multiple telescopic components can be used to connect the fixed column and the sleeve. Springs and damping blocks are installed inside the multiple telescopic components. When the machine head and the door body are impacted or collided, the sleeve can squeeze the telescopic component, and the impact can be buffered by the springs and damping inside the telescopic component, thereby reducing the impact on the rotating connection component and avoiding damage to the rotating connection component.

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0022] Example 1: Rotary connection structure of trackless telescopic gate motor head, see [link / reference] Figures 1 to 3The device includes a machine head body 1, with a control host 102 embedded in the top front end of the machine head body 1. A telescopic gate 101 is provided on the side of the machine head body 1. Multiple rotating wheels 103 are installed at the bottom of both the machine head body 1 and the telescopic gate 101. A rotating connection assembly is provided between the telescopic gate 101 and the machine head body 1. First, by using multiple bearings 203, a rotating cylinder 210, and a rotating shaft 208, connected to a first connecting rod 207 and a second connecting rod 209, flexible rotating connections can be made between the bearings 203 and the machine head, between the first connecting rod 207 and the second connecting rod 209, and between the gate 101 and the second connecting rod 209. This not only allows for a wider range of rotational movements between the machine head body 1 and the gate 101, but also enables them to smoothly complete relative displacement even at a large distance, improving the spatial adaptability and flexibility of the device. To further enhance the stability of the rotating connection assembly during rotation... To enhance load-bearing capacity, the system employs a combination of upper and lower dual bearings 203, connecting rods, a rotating shaft 208, and a rotating cylinder 210. This not only disperses the stress and friction generated during rotation but also improves the overall strength and durability of the structure by increasing support points. After the main body 1 and the gate 101 rotate to the predetermined position, the limiting plate 206 is connected to the rotating cylinder 210 and bearings 203 via fixing bolts 212. This restricts further rotation of the rotating connection assembly, ensuring that the gate 101 is in the correct installation or working position. This effectively prevents swaying or displacement caused by external forces, improving the stability and safety of the trackless telescopic gate. It also solves the technical problem in traditional trackless telescopic gates where a rotating connection method is used to connect the main body to the larger gate 101, which can easily cause the gate 101 to sway or shift when encountering external forces such as wind, affecting the stability of the gate 101.

[0023] For details, see Figure 2 The rotating connection assembly includes an L-shaped plate 2, a fixed column 201, a sleeve 202, a bearing 203, a first connecting rod 207, a rotating shaft 208, a second connecting rod 209, a groove 213, a fixed rod 211, a rotating cylinder 210, a limiting plate 206, and a fixing bolt 212.

[0024] Further, see Figure 2 Multiple L-shaped plates 2 are arranged on the side of the machine head body 1, and a fixing post 201 is fixed between two corresponding L-shaped plates 2. A sleeve 202 is sleeved on the outside of the fixing post 201, and a bearing 203 passes through the outside of the sleeve 202. The bearing 203 is rotatably connected to the sleeve 202.

[0025] It is worth noting that, see Figure 2One end of the first connecting rod 207 is fixed to one side of the bearing 203, and a rotating shaft 208 is fixed to the other end of the first connecting rod 207. A rotating cylinder 210 is fixed to the end of the rotating shaft 208 away from the first connecting rod 207. The rotating cylinder 210 is located in a groove 213 opened on the surface of the telescopic gate body 101. A fixing rod 211 passes through the inside of the rotating cylinder 210, and grooves 213 are fixed at both the upper and lower ends of the fixing rod 211.

[0026] It is worth noting that, see Figure 2 The front and rear ends of the rotating cylinder 210 and the bearing 203 are both fitted with limit plates 206. Both sides of the limit plates 206 are fitted with fixing bolts 212, which are threaded to the threaded grooves on the surfaces of the rotating cylinder 210 and the bearing 203.

[0027] It is worth mentioning that, see Figure 2 An electric telescopic cylinder 205 is fixed at the end of the L-shaped plate 2 away from the fixed column 201. The electric telescopic cylinder 205 is installed in the circular groove 204 opened on the side of the machine head body 1. After the electric telescopic cylinder 205 is opened, its piston rod can be precisely extended or shortened by the telescopic cylinder, thereby adjusting the distance between the door body 101 and the machine head. This allows the distance between the machine head and the door body 101 to be extended by an additional distance, thereby ensuring that the machine head can completely cover the target position. This solves the problem that the telescopic distance of the trackless telescopic gate is fixed during use, which leads to the situation in actual application where the door body 101 cannot meet the required coverage distance even after it is fully extended. Once this happens, it usually requires the staff to replace the entire trackless telescopic gate, which is not only cumbersome to operate but also costly, greatly reducing the flexibility and ease of use of the trackless telescopic gate.

[0028] It is worth emphasizing that, see Figure 3Multiple telescopic components are provided between the fixed column 201 and the sleeve 202. Each telescopic component includes a first fixed cylinder 3 and a second fixed cylinder 303 that are nested together. A damping block 302 is fixed to one end of the second fixed cylinder 303 inside the first fixed cylinder 3, and a spring 301 is fixed to the other end of the damping block 302 away from the second fixed cylinder 303. Inside each telescopic component, a spring 301 and a damping block 302 are provided. The spring 301, as an elastic element, can deform when compressed by external force, thereby absorbing and storing energy. The damping block 302, through its unique viscoelastic properties, dampens and controls the return process of the spring 301, slowing down the energy release rate. The telescopic component can respond quickly when impacted. Through the deformation of the spring 301 and the damping effect of the damping block 302, the impact is buffered together. When the machine head and the door body 101 are impacted or collided, the impact force will be transmitted along the structure to the telescopic component between the fixed column 201 and the sleeve 202. At this time, the sleeve 202 will squeeze the telescopic component, causing the spring 301 inside to deform and absorb the impact energy. At the same time, the damping block 302 also begins to play its role, damping and controlling the return process of the spring 301 to prevent the rapid release of energy and secondary impact. This effectively reduces the impact on the rotating connection component and avoids damage caused by excessive impact.

[0029] When using the rotating connection structure of the trackless telescopic gate motor head, firstly, multiple bearings 203, rotating cylinders 210, and rotating shafts 208 are connected to the first connecting rod 207 and the second connecting rod 209. This allows for flexible rotating connections between the bearings 203 and the motor head, between the first connecting rod 207 and the second connecting rod 209, and between the gate body 101 and the second connecting rod 209. This not only allows for a wider range of rotational movements between the motor head body 1 and the gate body 101, but also enables smooth relative displacement even at large distances, improving the spatial adaptability and flexibility of the device. To further enhance the rotating connection assembly during rotation... To ensure stability and load-bearing capacity during operation, a configuration of upper and lower dual bearings 203, connecting rods, rotating shaft 208, and rotating cylinder 210 is employed. This not only disperses the stress and friction generated during rotation but also enhances the overall strength and durability of the structure by increasing support points. After the main body 1 and the door 101 rotate to the predetermined position, the limiting plate 206 is connected to the rotating cylinder 210 and bearings 203 via fixing bolts 212. This restricts further rotation of the rotating connection assembly, ensuring that the door 101 is in the correct installation or working position. This effectively prevents swaying or displacement caused by external forces, thus improving the stability of the trackless telescopic gate. For safety and security, after opening the electric telescopic cylinder 205, its piston rod can be precisely extended or shortened to adjust the distance between the door body 101 and the machine head. This allows for an additional distance between the machine head and the door body 101, ensuring that the machine head can completely cover the target position. Inside each telescopic component, a spring 301 and a damping block 302 are installed. The spring 301, as an elastic element, deforms under external pressure, absorbing and storing energy. The damping block 302, through its unique viscoelastic properties, dampens and controls the return process of the spring 301, slowing down the energy release rate and ensuring the telescopic component... It can respond quickly when impacted. Through the deformation of spring 301 and the damping effect of damping block 302, the impact is buffered together. When the machine head and the door body 101 are impacted or collided, the impact force will be transmitted along the structure to the telescopic component between the fixed column 201 and the sleeve 202. At this time, the sleeve 202 will squeeze the telescopic component, causing the spring 301 inside to deform and absorb the impact energy. At the same time, the damping block 302 also begins to play its role, damping and controlling the return process of spring 301 to prevent the rapid release of energy and secondary impact. This effectively reduces the impact on the rotating connection component and avoids damage caused by excessive impact.
