Description

Technical Field

[0001] The utility model relates to the technical field of cylinders, in particular to a reverse stroke self-locking cylinder bottom structure. Background Art

[0002] The self-locking cylinder is a common pneumatic component. Its working principle is to use point pressure to control the movement of the piston, thereby realizing the self-locking function. The self-locking function of the self-locking cylinder is realized by valves and springs. When the air pressure acts on the valve, the valve will open, the gas can flow freely, and the piston can move. When the air pressure disappears, the valve will close, the gas cannot flow, and the piston will be locked in the current position. At the same time, the spring will also play a locking role to ensure that the piston will not move accidentally. The cylinder is a cylindrical metal part that guides the piston to perform linear reciprocating motion in the cylinder, and the cylinder base is one of the necessary parts in the cylinder.

[0003] The existing cylinder needs to be connected to the equipment at its base when in use. When the cylinder is connected to the equipment, threaded holes for installation need to be pre-set on the equipment, and the threaded holes in the set position cannot be changed. Due to different production and use conditions and different sizes of equipment, when the cylinder is connected to equipment of different sizes, the threaded holes on the reserved threaded holes on the equipment cannot be adjusted, resulting in the threaded holes on the cylinder bottom structure not being compatible with the threaded holes on the equipment, which makes it inconvenient to install cylinders of different sizes on a fixed base. In view of this, we propose a reverse stroke self-locking cylinder bottom structure. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a reverse stroke self-locking cylinder bottom structure to solve the technical problem that the threaded holes on the current cylinder bottom structure have a fixed spacing and are inconvenient to install with equipment of different sizes.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a reverse stroke self-locking cylinder bottom structure, including a cylinder bottom assembly placed at the bottom of the cylinder, the cylinder bottom assembly including a mounting plate, a cross groove is opened in the middle of the mounting plate, four mounting assemblies are symmetrically installed in the cross groove, the mounting assembly includes a connecting mechanism, the connecting mechanism is slidably connected to the cross groove, the side of the connecting mechanism is symmetrically installed with a first limiting ear and a second limiting ear, and a plurality of base grooves are opened in the cross groove for the first limiting ear and the second limiting ear to slide.

[0006] Preferably, circular plates are installed at both ends of the plurality of base grooves, and inspection grooves are provided at the inner corners of the cross grooves.

[0007] Preferably, a threaded rod is spirally connected in the first limiting ear, a sliding rod is slidably connected in the second limiting ear, the threaded rod is rotationally connected to the circular plate, and the sliding rod is fixedly connected to the circular plate.

[0008] Preferably, one end of each of the threaded rods extends out of the side surface of the circular plate, a rotating plate is installed at the end of the extended portion of the threaded rod, and a buckle for rotating the rotating plate is installed on the outer side of the rotating plate.

[0009] Preferably, the four connecting mechanisms are placed inside the cross groove and slide independently, and a thread groove for installation is provided inside the connecting mechanism.

[0010] Preferably, a slot spirally connected to the threaded rod is defined in the first limiting ear, and a through slot slidably connected to the sliding rod is defined in the second limiting ear.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model connects the cylinder and the equipment by adopting a connecting mechanism that slides in the base, and by opening a threaded groove for installation in the connecting mechanism instead of the existing method of directly opening a threaded hole on the base. During installation, the position of the connecting mechanism in the cross groove can be adjusted according to the position of the threaded hole opened on the equipment, so that the threaded groove in the connecting mechanism is directly opposite to the position of the threaded hole on the equipment, so that the cylinder can be installed on different equipment, which solves the technical problem that the threaded hole spacing on the cylinder bottom structure is fixed and it is inconvenient to install with equipment of different sizes.

[0013] 2. The present invention uses a new type of method to drive the threaded rod to rotate by rotating the buckle on the rotating plate. The threaded rod cooperates with the first limiting ear screw to drive the connecting mechanism to move in the cross groove, thereby completing the adjustment of the position of the connecting mechanism. The position adjustment of the corresponding connecting mechanism is completed through an independent threaded rod, which is convenient for later maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
