As shown in fig. 1 to 3, the high-strength mechanical latch 100 for a sedan door of the present utility model includes a base 1, a latch hook 2, a handle 3, a first elastic member 4 and a second elastic member 5, where the first elastic member 4 and the second elastic member 5 are torsion springs. The base body 1 comprises a surface cover 1a and a base 1b, wherein the surface cover 1a is fixedly connected with the base 1b, and a containing space for the lock hook 2 and the handle 3 is formed in the middle. A first opening 11 is formed in one side of the base 1, a second opening 21 is formed in one end of the latch hook 2, and a clamping portion 22 is formed in the other end, opposite to the second opening 21; the middle part of the latch hook 2 is pivoted to the base 1 through a rotating shaft 1c, so that the second opening 21 at least partially overlaps with the outlet of the first opening 11 when rotating to one side, or the second opening 21 is staggered with the outlet of the first opening 11 when rotating to the other side; the first elastic member 4 is disposed between the base 1 and the latch hook 2 to provide an elastic force for staggering the second opening 21 from the first opening 11; a locking concave 31 is arranged on one side of the handle 3 close to the locking part 22, the handle 3 is pivoted to the base 1 through a pivot shaft 1d, so that the locking concave 31 and the locking part 22 are mutually locked when the handle is pivoted close to the lock hook 2, or the locking concave 31 is separated from the locking part 22 when the handle is pivoted away from the lock hook 2; the second elastic member 5 is disposed between the base 1 and the handle 3, so as to provide an elastic force for making the handle 3 approach the latch hook 2.

Referring to fig. 1 and 2, the base 1 is provided with a first limiting member 12, the latch hook 2 is provided with a first limiting portion 23, and the first limiting portion 23 may abut against the first limiting member 12 to prevent the latch hook 2 from over-rotating. The seat body 1 is provided with a second limiting part 13, the handle 3 is provided with a second limiting part 32, the second limiting part 32 is arranged at the edge of one end of the handle 3, which is close to the pivot shaft 1d, in an outward protruding manner, and the second limiting part 32 can be propped against the second limiting part 13 so as to prevent the handle 3 from excessively rotating.

As further shown in fig. 3, the high strength mechanical latch 100 further includes a joint 6, where the joint 6 is pivotally connected to the handle 3. By arranging the joint 6, the handle 3 can be conveniently operated, and the convenience of operation is improved. Specifically, the side wall of the joint 6 is radially provided with a through hole 62, the outer end of the joint 6 is axially provided with a connecting hole 61, the connecting hole 61 is communicated with the through hole 62, the connecting hole 61 is provided with a screw 63, and the screw 63 extends into the through hole 62. Through the arrangement of the through holes 62, the handle 3 can be fixedly connected with the flexible piece through the screws 63, so that the handle 3 is driven to act through the flexible piece, and the operation is convenient.

When the shaft body 200 needs to be locked on the base 1, the shaft body 200 is only required to be directly placed into the first opening 11, the shaft body 200 enters the second opening 21 while entering the first opening 11, and then the shaft body 200 pushes the latch hook 2, so that the latch hook 2 rotates. When the shaft body 200 completely enters the first opening 11, the outlet of the second opening 21 of the locking hook 2 is just staggered from the outlet of the first opening 11, so that the shaft body 200 is completely blocked in the first opening 11, and locking is achieved. At the same time, the engaging portion 22 at the other end of the latch hook 2 is just engaged in the engaging recess 31 of the pull handle 3, and both are kept in a locked state by the elastic force of the second elastic member 5. When the shaft body 200 needs to be unlocked, the handle 3 is driven by the flexible member or directly to rotate around the pivot shaft 1d against the elastic force of the second elastic member 5, and the engaging recess 31 of the handle 3 is far away from the latch hook 2, so that the engaging recess 31 is separated from the engaging portion 22. At this time, the latch hook 2 rotates around the rotation shaft 1c under the elastic force of the first elastic member 4, so that the outlet of the second opening 21 is turned upward and at least partially overlaps with the outlet of the first opening 11. At this time, the shaft body 200 locked in the first opening 11 may be separated from the seat body 1, so as to realize unlocking.

Compared with the prior art, the utility model has the advantages that the first opening 11 is formed in the base body 1, the second opening 21 is formed in the lock hook 2, and the lock hook 2 is pivoted on the base body 1, so that the second opening 21 and the outlet of the first opening 11 can be at least partially overlapped or completely staggered when the lock hook 2 rotates, and a shaft body with larger stress can enter the first opening 11 and be locked by the lock hook 2. The other end of the latch hook 2 is provided with the clamping part 22, and the handle 3 is pivoted on the seat body 1 and the handle 3 is provided with the clamping concave 31, so that the clamping part 22 can be locked by the clamping concave 31, and the latch hook 2 can not rotate; the handle 3 can achieve the locking purpose only by the elastic force provided by the second elastic piece 5, so that a user only needs to apply small force to overcome the elastic force of the second elastic piece 5 during operation, and then the first elastic piece 4 is used for driving the latch hook 2 to rotate, so that the shaft body with large stress in the first opening 11 can be unlocked, the strength is high, the operation is very simple, the time and the labor are saved, and the use is very convenient.
