[0018] 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.

[0019] This utility model provides, for example Figures 1-3 The illustrated tripping latch crank arm assembly includes a main rod 1, secondary rods 2, a connecting mechanism 3, and a locking mechanism 4. The secondary rods 2 are respectively located at the top and bottom of the main rod 1. The connecting mechanism 3 is located outside the main rod 1. The locking mechanism 4 is located between the secondary rods 2 and is used to fix the secondary rods 2 and the connecting mechanism 3. The locking mechanism 4 connects the main rod 1, the two secondary rods 2, and the connecting mechanism 3 into a complete crank arm. When any component of the main rod 1, the two secondary rods 2, or the connecting mechanism 3 is damaged, it can be disassembled and replaced individually without replacing the entire assembly. This effectively reduces maintenance costs and material waste, significantly shortens equipment downtime, improves maintenance efficiency, and facilitates use.

[0020] Specifically, the connecting mechanism 3 includes a first connecting member 31, a second connecting member 32, a third connecting member 33, a fourth connecting member 34, and a connecting plate 35. The first connecting member 31 is equidistantly disposed on one side of the main rod 1, the second connecting member 32 is disposed on the other side of the main rod 1, the third connecting member 33 is disposed on the other side of the main rod 1, and the fourth connecting member 34 is disposed on the other side of the main rod 1. The connecting plate 35 is fixedly connected to the first connecting member 31, the second connecting member 32, the third connecting member 33, and the fourth connecting member 34 respectively. A connecting groove is formed on the outer wall of the main rod 1, and the connecting plate 35 is slidably inserted into the inner cavity of the connecting groove. The slots allow the first connector 31, the second connector 32, the third connector 33, and the fourth connector 34 to be connected to the main rod 1, facilitating the subsequent insertion and positioning of the locking rod 41. This enables the first connector 31, the second connector 32, the third connector 33, and the fourth connector 34 to be integrated with the main rod 1. If any of the first connector 31, the second connector 32, the third connector 33, and the fourth connector 34 are damaged, the damaged component can be replaced by releasing the locking rod 41.

[0021] Specifically, the locking mechanism 4 includes a locking rod 41, a sliding rod 42, a slider 43, a locking plate 44, and a compression spring 45. One end of the locking rod 41 is fixedly connected to the top of one of the auxiliary rods 2. A locking hole for engaging the locking rod 41 is provided on the connecting plate 35. A locking groove is provided at the bottom of the other auxiliary rod 2. The other end of the locking rod 41 passes through the locking hole and slides into the inner cavity of the locking groove. An elastic groove is provided at the top of the locking groove. The end of the sliding rod 42 slides into the inner cavity of the elastic groove. The slider 43 slides into the sliding rod 42. The locking plate 44 is fixedly connected to the bottom of the slider 43. A positioning groove is provided on one side of the locking rod 41. The locking plate 44 slides into the inner cavity of the positioning groove. The compression spring 45 is sleeved on the outside of the sliding rod 42. One end of the compression spring 45 is fixedly connected to the slider 43, and the other end of the compression spring 45 is fixedly connected to the inner wall of the elastic groove. Spring 45 provides a stable elastic force to snap-fit ​​plate 44 through slider 43, thereby enabling snap-fit ​​plate 44 to be inserted and positioned with snap-fit ​​rod 41 that intersects and positions the first connector 31, second connector 32, third connector 33 and fourth connector 34. This allows the two auxiliary rods 2 to be fixed to the ends of the main rod 1, and the first connector 31, second connector 32, third connector 33 and fourth connector 34 to be fixed to the main rod 1 for easy use.

[0022] Furthermore, the cross-section of the snap-fit ​​plate 44 is C-shaped, and the outer wall of the other auxiliary rod 2 is provided with a through groove for sliding the snap-fit ​​plate 44. The outer wall of the snap-fit ​​plate 44 is provided with a pull groove, the cross-section of which is L-shaped. The pull groove is designed to facilitate the insertion of an external tool into the groove, thereby allowing the snap-fit ​​plate 44 to move within the through groove by pulling. This causes the snap-fit ​​plate 44 to disengage from the snap-fit ​​hole on the snap-fit ​​rod 41, thus releasing the positioning of the snap-fit ​​rod 41. This allows the entire crank arm assembly to be disassembled, facilitating the replacement of any damaged parts.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
