Description

Technical Field

[0001] This utility model relates to the field of parking lots, and more specifically, to an electric unlocking device for four-post parking. Background Technology

[0002] Currently, stacked four-post parking systems on the market have multiple layers of vehicle-carrying platforms. To ensure the safety of these multiple platforms in the future, it is necessary to configure corresponding limit blocks separately to support and limit them from the bottom, preventing them from falling and improving the safety of parking.

[0003] In the existing limit block structure, each layer requires a separate electric actuator to control the position, making it impossible to unlock multiple layers of fall arrestors simultaneously. All of them only have fall arrest devices. The four-post parking of the vehicle platform has four fall arrest locks, which require four electromagnets to unlock simultaneously to achieve the function. The wiring is complicated and prone to failure. There is a lack of combined limit blocks to connect the mounting cylinder and the actuator, and it is impossible to use a single electric actuator to control the multi-layer structure. The adaptability is poor and needs to be improved. Utility Model Content

[0004] To address the problems existing in the prior art, the purpose of this utility model is to provide an electric unlocking device for four-post parking. By installing a loading platform and an upper loading platform inside the column, vehicles can be parked in multiple layers. Support shafts and limiting blocks are installed on the side fixing plates, providing limiting support for each layer, ensuring high safety. At the same time, the bottom hinged electric push rod, combined with the side combination seat to install connecting rings and mounting cylinders, connects the first push rod and the second push rod, enabling combined connection and positioning, facilitating unified control operation, high adaptability, and easy adjustment.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] An electric unlocking device for four-post parking includes a column. A loading platform and an upper loading platform are slidably mounted on the inner ends of the column. A fixing plate is fixedly connected to the side of the column. A support shaft is fixedly connected to the surface of the fixing plate. A lower limit block and an upper limit block are rotatably mounted on the surface of the support shaft. A support seat is provided on the lower surface of both the lower and upper limit blocks. An electric push rod is hinged to one side of the support seat and is hinged to one side surface of the fixing plate. A combined seat is provided at the rear end of the lower and upper limit blocks. A connecting ring is hinged inside the combined seat. A mounting cylinder is fixedly connected to one end of the connecting ring. A first push rod is fixedly connected to one end of the mounting cylinder. A protective cylinder and a second push rod are combined and mounted on one end of the first push rod. The second push rod is hinged to one end of the lower limit block through the mounting cylinder.

[0007] Furthermore, the head of the first push rod is fixedly connected to a first connector, which is slidably connected inside the protective cylinder.

[0008] Furthermore, the head of the second push rod is fixedly connected to a second connector, which is tightly connected to the lower surface of the first connector.

The first connector is installed through the first push rod, and the second connector and the protective spring are installed together through the second push rod. They can be connected to the inside of the protective cylinder for combined positioning. Thus, they can be pushed upward to achieve unified unlocking, and pulled downward to extend and avoid pressure, thereby improving operational safety.

[0010] Furthermore, a fixing block is fixedly connected to the side of the mounting cylinder, and the surface of the fixing block is provided with a positioning groove.

[0011] Furthermore, a tensioning steel cable is fixedly connected to one side of the fixing block, and both ends of the tensioning steel cable are fixedly connected to the inside of the positioning groove through a winding head.

[0012] Furthermore, an anchor head is fixedly riveted to one side of the winding head. The anchor head is fixedly riveted to both ends of the tension cable and connected to the fixing block through the installation cylinder, thereby installing the tension cable and the anchor head. It can bear the tension force, improve the strength of use, and the upper and lower layers will not interfere with each other, ensuring safety and stability.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] (1) This solution allows for multi-level vehicle parking by installing a loading platform and an upper loading platform inside the column. Support shafts and limit blocks are installed on the side fixing plates, providing limit support for each layer, ensuring high safety. At the same time, the bottom hinged electric push rod, combined with the side combination seat to install connecting rings and mounting cylinders, allows for the combined connection and positioning of the first push rod and the second push rod, facilitating unified control and operation, high adaptability, and easy adjustment and use.

[0015] (2) The first connector is installed by the first push rod, and the second connector and the protective spring are installed by the second push rod. It can be connected to the inside of the protective cylinder for positioning. It can be pushed upward to achieve unified unlocking, and pulled downward to extend and avoid, reduce pressure, and improve operational safety.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1 , Figure 2 and Figure 3An electric unlocking device for four-post parking includes a column 1. A loading plate 11 and an upper loading plate 12 are slidably installed on the inner ends of the column 1. A fixing plate 13 is fixedly connected to the side of the column 1. A support shaft 14 is fixedly connected to the surface of the fixing plate 13. A lower limit block 15 and an upper limit block 16 are rotatably installed on the surface of the support shaft 14. A support seat 17 is provided on the lower surface of both the lower limit block 15 and the upper limit block 16. An electric push rod 18 is hinged to one side of the support seat 17 and is hinged to one side surface of the fixing plate 13. A combination seat 2 is provided at the rear end of the lower limit block 15 and the upper limit block 16. A connecting ring 21 is hinged inside the combination seat 2. An installation cylinder 22 is fixedly connected to one end of the connecting ring 21. A first push rod 23 is fixedly connected to one end of the installation cylinder 22. A protective cylinder 24 and a second push rod 25 are combined and installed at one end of the first push rod 23. The second push rod 25 is hinged to one end of the lower limit block 15 through the installation cylinder 22.

[0026] Please see Figure 2 , Figure 3 and Figure 5 The first push rod 23 has a first connector 33 fixedly connected to its head, which is slidably connected inside the protective cylinder 24. The second push rod 25 has a second connector 34 fixedly connected to its head, which is pressed against the lower surface of the first connector 33. A protective spring 35 is fixedly connected to one side of the second connector 34, and the protective spring 35 is slidably installed inside the protective cylinder 24. By installing the first connector with the first push rod and the second connector and protective spring with the second push rod, they can be connected to the inside of the protective cylinder for positioning. This allows for upward pushing to unlock the cylinder and downward pulling to extend and avoid pressure, improving operational safety. The second connector 34 connects to the first connector 33. The upper limit block 15 can be adjusted by pushing it upwards. After the electric push rod 18 retracts, it pulls the front end of the lower limit block 15 downwards and flips it down, thus unlocking it electrically. This facilitates the adjustment of the lifting and lowering of the download platform 11. The rear end of the lower limit block 15 will move upwards, which will push the first push rod 23 upwards with the second push rod 25. This will cause the rear end of the upper limit block 16 to flip upwards, and the front end will rotate downwards to unlock it. A single electric push rod 18 can control a multi-layer structure, which is safe, stable, and highly adaptable. When the second push rod 25 is pushed downwards, the second connector 34 can compress the protective spring 35 downwards, thus extending it slightly to avoid interference caused by the vertical installation spacing error. This improves the matching adaptability and facilitates combined use.

[0027] Please see Figure 2 , Figure 3 and Figure 4A fixing block 26 is fixedly connected to the side of the mounting cylinder 22. The surface of the fixing block 26 is provided with a positioning groove 27. A tensioning steel cable 3 is fixedly connected to one side of the fixing block 26. The two ends of the tensioning steel cable 3 are fixedly connected to the inside of the positioning groove 27 through the winding head 31. An anchor head 32 is fixedly riveted to one side of the winding head 31. The anchor head 32 is fixedly riveted to both ends of the tensioning steel cable 3. The fixing block is connected to the mounting cylinder, thereby installing the tensioning steel cable and the anchor head. It can bear the tension force, improve the strength of use, and the upper and lower layers will not interfere with each other, which is safe and stable. The tensioning steel cable 3 is connected to the mounting cylinder 2 and the fixing block 26 at both ends, which can be combined and connected for positioning. After the lower limit block 15 is tightened and fixed by the electric push rod 18, it can provide limit support for the lower vehicle plate 11. The tensioning steel cable 3 tightens the rear end of the upper limit block 16, thereby locking it. The front end cannot rotate around the support shaft 14, thus maintaining a stable horizontal state. It can provide limit support for the upper vehicle plate 12, which is safe, stable, and highly adaptable.
