[0033] In the description of the utility model, it is necessary to explain, unless otherwise expressly provided and limited, the terms "mounting", "connecting", "connecting", "setting" should be understood broadly, for example, it can be fixedly connected, can also be detachably connected, or integrally connected; can be mechanically connected, can also be electrically connected; can be directly connected, can also be indirectly connected through an intermediate medium, can be the communication between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances. The embodiments will be described below according to the overall structure of the utility model.

[0034] For example, Figures 1-4The utility model discloses a lock catch device of a blade type rail breaker, which comprises a gate assembly 1, a release mechanism 2, a lock catch mechanism 3 and a poking mechanism 4. The gate assembly 1 comprises a vertically movable gate 11. The release mechanism 2 comprises a mounting seat 21, a hook 22 and a first spring 23. The mounting seat 21 is arranged on the outer side of the gate 11. The hook 22 is rotatably connected to the mounting seat 21. The upper end of the gate 11 is hung on one side of the hook 22. The first spring 23 is arranged on the other side of the hook 22 and is used to give the one side of the hook 22 a downward rotating force. The bottom of the hook 22 is provided with a protrusion 223. The lock catch mechanism 3 comprises a buckle 31 and a second spring 32. The buckle 31 is arranged below the hook 22 and is rotatably connected to the mounting seat 21 at one end. The middle part of the buckle 31 is provided with a stepped structure. When the protrusion 223 and the stepped structure are mutually clamped, the one side of the hook 22 is prevented from rotating downward, so that the upper end of the gate 11 can be firmly and reliably hung on the hook 22. The second spring 32 is arranged at the other end of the buckle 31 and is used to give the buckle 31 a force for abutting against the hook 22. The poking mechanism 4 is used to drive the other end of the buckle 31 to rotate clockwise or counterclockwise. It can be understood that when the buckle 31 and the hook 22 are mutually abutted and clamped, the poking mechanism 4 can only drive the buckle 31 to rotate in a direction away from the hook 22, without being wrongly rotated. The operator can timely and accurately complete the operation of releasing the gate 11. When the buckle 31 and the hook 22 are mutually separated, the first spring 23 drives the hook 22 to rotate, so that the opening of the hook 22 is downwardly inclined. The gate 11 is released from the hook 22 and vertically falls due to the action of gravity.

[0035] With reference still to Figure 2 In the embodiment, a track 5 is further included. The mounting seat 21 and the gate 11 are vertically arranged above the track 5. The track 5 is provided with a gate opening 51 matched with the gate 11. When the gate 11 falls into the gate opening 51, the path of the track 5 is blocked by the gate 11. Specifically, the poking mechanism 4 comprises a fixed seat 41, a poking rod 42, a vertical rod 43, a sub rod 44 and a transmission mechanism 45. The fixed seat 41 is horizontally arranged on the track 5 and is arranged on the outer side away from the mounting seat 21 of the gate 11. The vertical rod 43 is rotatably connected to the fixed seat 41. The poking rod 42 is arranged on the outer side of the track 5 and is vertically arranged at one end of the vertical rod 43. The sub rod 44 is vertically arranged at the other end of the vertical rod 43. The poking rod 42 and the sub rod 44 are arranged in parallel and the length of the poking rod 42 is greater than that of the sub rod 44. One end of the transmission mechanism 45 is rotatably connected to the sub rod 44 and the other end is rotatably connected to the other end of the buckle 31.

[0036] With reference still to Figure 3The transmission mechanism 45 comprises a first connecting rod 451, a second connecting rod 452 and a third connecting rod 453. The upper end of the first connecting rod 451 is hingedly connected to the other end of the buckle 31, and the lower end is hingedly connected to the upper end of the second connecting rod 452. The upper end of the second connecting rod 452 is also hingedly connected to one end of the third connecting rod 453. The lower end of the second connecting rod 452 is rotatably connected to the mounting base 21, and the other end of the third connecting rod 453 is hingedly connected to the auxiliary rod 44. The lever structure formed by the combination of the lever 42, the vertical rod 43, the auxiliary rod 44, the first connecting rod 451, the second connecting rod 452 and the third connecting rod 453 enables the operator to use less force to drive the buckle 31 and the hook 22 to separate from each other.

[0037] In addition, the lever mechanism 4 in the embodiment further comprises a third spring 46. The lower end of the third spring 46 is fixed below the mounting base 21, and the upper end is connected to the second connecting rod 452. When the buckle 31 and the hook 22 abut against each other to be locked, the lever 42 remains in a vertical downward state, ensuring that the lever 42 can be triggered to release the gate 11 by rotating a certain angle under the action of external force. It is worth noting that the upper end of the third spring 46 is detachably connected to the middle part of the second connecting rod 452. After the buckle 31 and the hook 22 are separated from each other, the buckle 31 is rotated in the direction of approaching the hook 22 under the action of the second spring 32. The third spring 46 is arranged as a tension spring, which can provide a pulling force to the buckle 31 through the second connecting rod 452 and the third connecting rod 453 to rotate in the direction away from the hook 22, thereby avoiding the buckle 31 from excessively approaching the hook 22, which causes the hook 22 to fail to be smoothly reversed.

[0038] Further, the lower part of the track 5 is in a groove shape, and the upper part is in a planar shape. The path of the track 5 is arranged in the groove. When the gate 11 completely falls into the gate opening 51, the groove of the track 5 is closed by the gate 11. It can be understood that the gate 11 extends to both sides of the track 5, the top is higher than the surface of the track 5, and the bottom extends to the bottom of the track 5, which can completely seal and block the groove.

[0039] Continuing to refer to Figure 3 , Figure 4 The gate assembly 1 in the embodiment further comprises a protective cover 12 and a guide rod 13. The protective cover 12 is arranged on the track 5 above the gate opening 51, and the guide rod 13 is vertically arranged in the protective cover 12. The gate 11 is vertically movably arranged in the protective cover 12 and is slidably connected with the guide rod 13. The upper and lower ends of the mounting base 21 are respectively connected with the protective cover 12. Preferably, in order to accelerate the falling speed of the gate 11, a fourth spring 14 can be sleeved on the guide rod 13, and the upper end of the gate 11 is sleeved on the guide rod 13. The fourth spring 14 can exert a downward pushing force on the upper end of the gate 11.

[0040] Further, the hook 22 in the embodiment is provided in a C-shaped structure, the hook 22 comprises a round hole 221 and a fastening bolt 222, the round hole 221 is arranged near the upper left of the C-shaped structure, the fastening bolt 222 is arranged at the left side of the C-shaped structure, a protrusion 223 is arranged near the lower left of the C-shaped structure, the round hole 221 is rotatably connected with the mounting base 21 through a pin shaft, the upper end of the first spring 23 is fixed above the mounting base 21, and the lower end pulls the fastening bolt 222. Specifically, the first spring 23 is provided as a tension spring, and the lower end is detachably connected with the fastening bolt 222, when the buckle 31 and the hook 22 are separated from each other, the hook 22 is pulled by the first spring 23 to rotate in a clockwise direction, the opening of the hook 22 is inclined downward, and the upper end of the gate 11 is separated from the lower end of the opening of the hook 22.

[0041] It can be understood that when an external force lifts the gate 11 upward, the upper end of the gate 11 can abut on the upper end of the opening of the hook 22 and drive the hook 22 to rotate in an anticlockwise direction, when rotating to a position where the protrusion 223 and the stepped structure in the middle of the buckle 31 are engaged with each other, the external force is released so that the upper end of the gate 11 can be hung in the opening of the hook 22.

[0042] Further, the second spring 32 is provided as a tension spring, and the upper end is fixed above the mounting base 21, and the lower end pulls the other end of the buckle 31, the lower end of the second spring 32 is detachably connected with the buckle 31, the mounting base 21 and the fixing base 41 are both arranged at the left side of the gate 11, the second spring 32 is arranged at the left side of the first spring 23, and the first spring 23 is arranged at the left side of the mounting base 21, so that the second spring 32 and the first spring 23 can be prevented from interfering with each other.

[0043] The foregoing description of specific exemplary embodiments of the present application is intended to be illustrative only and is not intended to be limiting as to the scope of the present application. These descriptions are not intended to limit the application to the precise forms or particular fields of use disclosed. As such, many modifications and variations will be apparent to practitioners skilled in this art. It is contemplated that the application be practiced otherwise than as specifically described herein.
