DETAILED DESCRIPTION

[0018] The features and exemplary embodiments of each aspect of the present application will be described in detail below, in order to make the purpose, technical scheme and advantages of the present application more clear and apparent, the present application will be further described in detail below in combination with the drawings and specific embodiments. For those skilled in the art, the present application can be implemented without some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by showing examples of the present application.

[0019] As Figure 1 , Figure 2 andFigure 3 As shown, this utility model provides a technical solution for a long-stroke guide interlock mechanism for a hydraulic cylinder: it includes a hydraulic cylinder body 1, and a hydraulic rod 14 is provided inside the hydraulic cylinder body 1. A pin head 15 is provided at the front end of the hydraulic rod 14, and a locking slot 16 is provided on the pin head 15. A locking seat 2 is provided outside the pin head 15, and locking grooves 21 are provided at both the front and rear ends of the locking seat 2. Two sets of locking pins 22 are symmetrically arranged in the locking grooves 21, and the locking pins 22 cooperate with the locking slots 16.

[0020] Among them, such as Figure 2 As shown, the locking pin 22 is embedded in the inner wall of the locking groove 21 and slidably connected thereto. A spring 24 is provided between the locking pin 22 and the locking seat 2 so that the locking pin 22 can automatically reset when subjected to external force.

[0021] like Figure 3 As shown, a pressing part 23 is provided on the side of the locking pin 22 near the opening of the locking groove 21, which is used to press the locking pin 22 and compress the spring 24 when the pin head 15 is inserted. When the pin head 15 is inserted into the lock seat 2, the pressing part 23 presses the locking pin 22, causing the locking pin 22 to move inward and the spring 24 to be compressed. After the pin head 15 passes through the lock opening 16, the spring 24 pushes the locking pin 22 to return to its original position, thereby realizing the interlocking function.

[0022] The hydraulic cylinder body 1 has an oil inlet 11 and an oil outlet 12 on its outer wall. Oil passages 13 are provided inside the oil inlet 11 and oil outlet 12, and these passages are connected to the hydraulic cylinder body 1. By controlling the input and output of hydraulic oil, the reciprocating motion of the hydraulic cylinder can be achieved.

[0023] The locking groove 21 fits tightly with the column head 15, ensuring that the locking column 22 and the locking port 16 can fit tightly when the hydraulic cylinder performs a long stroke, thereby improving the stability and safety of the equipment.

[0024] Through the above structural design, the hydraulic cylinder long-stroke guide interlock mechanism of this utility model can effectively realize the guide interlock of the hydraulic cylinder during long-stroke movement, improving the stability and safety of the equipment. At the same time, due to its relatively simple structure, it is easy to manufacture and maintain, reducing costs and improving the reliability and service life of the equipment.
