[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: A hinged, equally divided pitch variable mechanism, such as... Figures 1-4 As shown, it includes a mounting plate 1, a movable block 3, a hinge assembly 4, a guide shaft 5, and a mounting base 6. Two mounting bases 6 are fixedly connected to one side of the mounting plate 1. The guide shaft 5 is fixedly connected to the opposite side of the two mounting bases 6. The movable block 3 is movably mounted on the guide shaft 5. The hinge assembly 4 is provided on the side of the movable block 3 facing away from the mounting plate 1. The hinge assembly 4 is connected to the movable block 3 and one of the mounting bases 6.

[0025] like Figures 1-2 As shown, the mounting plate 1 has multiple mounting holes for mounting equipment components. A drive cylinder 7 is mounted on one side of the mounting plate 1 through the mounting holes. The piston rod of the drive cylinder 7 is connected to a floating joint 2. There are no fewer than two guide shafts 5, and the multiple guide shafts 5 are arranged vertically. Here, the design of the drive cylinder 7 can reduce the inconvenience caused by manual adjustment by workers and effectively improve work efficiency and the accuracy of adjustment.

[0026] like Figures 2-4 As shown, the floating joint 2 has an L-shaped structure. The end of the floating joint 2 away from the drive cylinder 7 is connected to the moving block 3. The moving block 3 consists of an oil-storage linear bearing 31 and a moving plate 32. The oil-storage linear bearing 31 is installed on the moving plate 32. The moving plate 32 is connected to the guide shaft 5 through the oil-storage linear bearing 31. The top of the moving plate 32 of the moving block 3 is fixedly connected to the floating joint 2. Here, the design of the oil-storage linear bearing 31 can effectively avoid direct contact between the moving plate 32 and the guide shaft 5, reduce the frictional loss generated during the movement of the moving plate 32, and extend the service life of the device.

[0027] like Figures 3-4 As shown, the movable plate 32 is provided with hinge connecting bolts 33. The movable plate 32 is hinged to the hinge group 4 through the hinge connecting bolts 33. The hinge group 4 is formed by multiple rods hinged to each other, and each rod is arranged in a sawtooth shape to form multiple parallelogram structures. Multiple movable plates 32 are provided on the guide shaft 5, and each movable block 3 is connected to the intersection of the hinge group 4.

[0028] This device is a hinged, equally spaced, variable-distance mechanism, typically used in applications requiring adjustment of the distance between objects, such as material gripping, sorting, or transfer operations on automated production lines. When in use, the mounting plate 1 is installed in a predetermined operating position to secure the device. Then, the grippers are mounted on the moving plate 32, which is away from the drive cylinder 7. The drive cylinder 7 is then activated, causing the piston rod to extend outwards. The piston of the drive cylinder 7 drives the floating joint 2 to move away from the drive cylinder 7, which in turn moves the connected moving plate 32 away from the drive cylinder 7. During this movement, the moving plate 32 applies tension to the hinge assembly 4, causing it to extend. Simultaneously, the hinge assembly 4 applies force to the connected moving plate 32, causing each moving plate 32 to move synchronously on the guide shaft 5, thus completing the distance adjustment.

[0029] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
