DETAILED DESCRIPTION

[0024] A standing platform for out-of-cabin operations on the top of a vehicle comprises a standing platform 1, an extension platform 2, a support structure and a vehicle body connector 9, wherein the support structure comprises two front telescopic legs and two rear telescopic legs, the two front telescopic legs and the two rear telescopic legs are respectively hinged to the front and rear sides of the bottom of the standing platform through a folding hinge shaft 14, the bottoms of the two front telescopic legs are hinged to the vehicle body connector through a folding hinge shaft, and the extension platform consists of two extension platforms respectively hinged to the left and right sides of the standing platform through a folding hinge shaft, which facilitates the folding between the legs and the platform, the folding between the legs and the vehicle body connector, and the folding between the extension platform and the standing platform, does not affect the space utilization of special vehicles and can adapt to the requirements of different height conditions and working environments.

[0025] The folding hinges between the bottom of the front telescopic leg and the vehicle body connecting part, the folding hinges between the front telescopic leg and the standing platform, the folding hinges between the rear telescopic leg and the standing platform, and the folding hinges between the extension platform and the standing platform are respectively provided with folding locking mechanisms 8, and the telescopic parts of the two front telescopic legs and the two rear telescopic legs are respectively provided with telescopic locking mechanisms, so that the folding and supporting operations of the platform are relatively stable and reliable.

[0026] Furthermore, the front telescopic leg includes a front leg 10 and a front leg telescopic leg 12 located at the upper part of the front leg, and the rear telescopic leg includes a rear leg 4 and a rear leg telescopic leg 6 located at the lower part of the rear leg. The ends of the front leg and the rear leg are respectively provided with leg locking holes, and the front leg telescopic leg and the rear leg telescopic leg are provided with multiple telescopic leg locking holes. The telescopic locking mechanism is a limiting pin 5, which passes through the locking holes of the corresponding leg and the leg telescopic leg to lock the leg and the leg telescopic leg. The different locking holes on the leg telescopic leg correspond to the locking holes on the leg and are then locked by the limiting pin. The height of the corresponding leg can be adjusted and locked. The operation is simple and the leg support is more reliable.

[0027] Furthermore, baffles 11 are respectively fixed on the front and rear legs by bolts to block the corresponding leg locking holes. After the legs are locked by the limiting pins, the baffles are placed on the outside of one end of the limiting baffle of the limiting pin to prevent the limiting pin from withdrawing. When unlocking, you only need to rotate the baffle to make the baffle leave the leg locking hole, and then push the bottom end of the limiting pin without the baffle outwards, so that the limiting pin can be easily taken out and unlocked. The operation is very convenient and labor-saving.

[0028] Furthermore, the folding locking mechanism includes a pin seat 15, a locking pin 16, a spring 22 and a pull rod 20. The pin seat is fixedly mounted on the lower surface of the standing platform or the vehicle body connecting piece at a position corresponding to the corresponding folding pin shaft. The locking pin is installed in the pin seat and extends out of the pin seat. The spring is located in the pin seat and is sleeved on the locking pin. The pull rod is provided with an external thread and is threadedly connected to the rear end of the locking pin and is locked by a locking nut 19. The folding hinge shaft is provided with a locking groove (not shown) at a position corresponding to the locking pin. The front end of the spring is limited by the shoulder on the locking pin, and the rear end is limited by the pin seat. When locking is required, just push the pull rod forward to insert the locking pin forward into the locking groove of the corresponding folding hinge shaft to prevent the folding hinge shaft from flipping. When unlocking, just pull the pull rod outward, which is simple and labor-saving to operate.

[0029] Furthermore, two clearance grooves 18 are provided on the outer wall of the rear end of the pin seat, and a radial pin hole 23 is opened on the locking pin, and a pin 17 is installed at the radial pin hole. When locking, the pin is located at the clearance groove at the rear end of the pin seat, the spring is in a compressed state, and the locking pin extends forward to the locking groove of the corresponding folding hinge shaft. When unlocking, the pull rod is pulled outward and rotated to make the pin disengage from the clearance groove at the rear end of the pin seat and get stuck at the rear end of the pin seat. Then, after flipping the corresponding folding mechanism, the pull rod is pulled outward and rotated to make the pin correspond to the clearance groove at the rear end of the pin seat, and then the locking pin can be locked by releasing the hand, which further facilitates the folding and locking operation.

[0030] Furthermore, a pull ring 21 is fixedly mounted on the end of the pull rod.

[0031] Furthermore, a front telescopic leg connecting plate 13 is fixedly installed between the two front telescopic legs, and a rear telescopic leg connecting plate 7 is fixedly installed between the two rear telescopic legs, so that the two front telescopic legs are connected together, and the two rear telescopic legs are connected together, thereby improving the stability of the overall structure.

[0032] Furthermore, the left and right sides of the standing platform are respectively hinged with extended platform legs 3. After the extended platform is opened, the extended platform legs can be rotated to form support for the extended platform, making the platform more stable and reliable.
