Description

Technical Field

[0001] The utility model relates to the technical field of locking cylinders, in particular to a high-safety locking cylinder for transportation equipment. Background Art

[0002] The main function of a locking cylinder in transport equipment is to ensure the stability and safety of the equipment during transportation. It can lock certain parts of the equipment to prevent displacement or falling due to vibration, bumps, or other external forces, thereby protecting the cargo and the equipment itself. The working principle of a locking cylinder usually involves using compressed air to control the movement of the cylinder's piston and achieving the locking function through a mechanical locking mechanism. When locking is required, the air pressure inside the cylinder pushes the piston to generate a locking force. This force is transmitted to the locking component through the mechanical structure to fix it in place; when unlocking is required, by adjusting the air pressure inside the cylinder or releasing the air pressure, the piston returns to its original position, the unlocking mechanism is released, and the locking component is allowed to move.

[0003] The existing locking cylinder may lose its locking force in the event of a sudden power outage. Although the existing spring-air pressure combined locking can still maintain a certain locking force when the power is off, the reduction in locking force still poses a safety hazard. The locking part may move under the action of external force, resulting in locking failure and inducing a safety accident. Utility Model Content

[0004] The purpose of the utility model is to provide a high-safety locking cylinder for transportation equipment to solve the problem that the existing locking cylinder may lose the locking force in the event of a sudden power outage, thereby causing locking failure and inducing safety accidents.

When the first output rod extends a preset length and the locking component is in a preset locking state, the first connecting rod is exactly parallel to the second connecting rod (such as Figure 3As shown in FIG, at this time, the first connecting rod and the second connecting rod are both in a dead point state, locking the first output rod to a preset position. Even if the locking cylinder is powered off, the first connecting rod and the second connecting rod will lock the first output rod, preventing external force from driving the first output rod to move, thereby enhancing the safety performance of the locking cylinder.

DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific implementation methods.

[0029] In this article, terms such as "upper, lower, inside, outside" are established based on the positional relationships shown in the drawings. Depending on the different drawings, the corresponding positional relationships may also change accordingly. Therefore, they cannot be understood as absolute limitations on the scope of protection; moreover, relational terms such as "first" and "second" are only used to distinguish one component from another with the same name, and do not necessarily require or imply any actual relationship or order between these components.

[0030] Example

[0031] like Figure 1-3 As shown, this embodiment provides a high-safety locking cylinder 1 for transportation equipment, including: a locking cylinder 1; a first output rod 13, the first output rod 13 is movably arranged on the locking cylinder 1, and the first output rod 13 extends out of the locking cylinder 1; a first slider 2, the locking cylinder 1 is installed on the first slider 2; a second slider 129, the first output rod 13 is connected to the second slider 129; a first connecting rod 17, the first connecting rod 17 is rotatably connected to the first slider 2; a second connecting rod 8, the second connecting rod 8 is rotatably connected to the second slider 129, and the second connecting rod 8 is rotatably connected to the first connecting rod 17.

[0032] Specifically, the first slider 2 is fixed, and when the locking cylinder 1 controls the first output rod 13 to extend, it drives the second slider 129 to move away from the first slider 2, thereby deflecting the first connecting rod 17 and the second connecting rod 8. When the first output rod 13 extends a preset length, so that the locking component is in a preset locking state, the first connecting rod 17 is exactly parallel to the second connecting rod 8 (such as Figure 3 As shown), at this time, the first connecting rod 17 and the second connecting rod 8 are both in the dead point state, locking the first output rod 13 to the preset position. Even if the locking cylinder 1 is powered off, the first connecting rod 17 and the second connecting rod 8 will lock the first output rod 13, so that external force cannot drive the first output rod 13 to move, thereby enhancing the safety performance of the locking cylinder 1.

[0033] Preferably, a first connecting rod 17 is provided on both sides of the first slider 2, and a second connecting rod 8 is provided on both sides of the second slider 129. The first connecting rod 17 on the same side is rotatably connected to the second connecting rod 8. By providing the first connecting rod 17 on both sides of the first slider 2, the safety performance of the locking cylinder 1 is further enhanced. The first output rod 13 is connected to a locking component, and the structure of the locking component is not specifically limited in this application.

When locking, the driving cylinder 18 can move along the slide rail driven by the first connecting rod 17 or the second connecting rod 8. When unlocking, the driving cylinder 18 drives the second output rod 7 to extend, providing a horizontal force to drive the first connecting rod 17 or the second connecting rod 8 to deflect. At this time, the locking cylinder 1 cooperates with the retraction of the first output rod 13 to unlock. Preferably, a driving cylinder 18 is provided on both sides of the third slider 6, and the second output rod 7 of the driving cylinder 18 on the same side is rotatably connected to the first connecting rod 17 or the second connecting rod 8.
