Referring to fig. 2-5, fig. 2 is a transverse cross-sectional view of the seat adjustment mechanism of fig. 1; FIG. 3 is a schematic view of the latch mechanism of the seat adjustment mechanism of FIG. 1; FIG. 4 is an enlarged view of a portion of the inner slide rail of the seat adjustment mechanism of FIG. 1; fig. 5 is a cross-sectional view of the latch mechanism of the seat adjustment mechanism of fig. 1 in a latched state.

In the utility model, the locking mechanism 3 is positioned in the inner slide rail 1 and is provided with annular locking teeth, as can be understood by combining fig. 2 and fig. 3, the transverse edges of the locking teeth penetrate through the inner tooth hole 1a, the locking teeth can move along the vertical direction, when the locking teeth are at the top, the locking teeth are simultaneously sleeved with the corresponding first locking part 1b and the second locking part 2b, the inner locking edge 31a in the locking teeth is rigidly limited with the locking hole end 1aa of the corresponding inner tooth hole 1a, and the outer locking edge 31b is rigidly limited with the corresponding tooth groove 2a, so that the locking function is realized; the locking tooth can also break away from and correspond second locking portion 2b and realize the unblock function, if when locking mechanism 3 received decurrent effort, the locking tooth just can follow vertical direction downstream, breaks away from second locking portion 2b, nevertheless the locking tooth still cartridge in interior tooth hole 1a, therefore when interior slide rail 1 removed, locking mechanism 3 can be along with interior slide rail 1 synchronous motion, locking mechanism 3 is fixed relatively with interior slide rail 1 promptly.

According to the utility model, the inner locking edge 31a in the locking tooth is rigidly limited with the inner sliding rail 1, and the outer locking edge 31b is rigidly limited with the outer sliding rail 2, so that on one hand, the inner sliding rail 1 and the outer sliding rail 2 do not move relatively under the locking state, and the riding comfort of customers is improved; on the other hand, the limiting mode only needs to ensure that the lock tooth body with the annular lock teeth in the locking mechanism 3 is made of rigid materials, and materials of other parts are not limited, namely, the rigid materials and the flexible materials can be adopted; and the lock tooth body 31 and the lock body 32 are fixed in an interference fit mode, so that the connection is stable and the structure is simple.

The lock body 32 is made of a flexible material, and may be made of plastic, nylon block, or the like.

As shown in fig. 4, in this embodiment, the number of the locking tooth bodies 31 having the annular locking teeth is four, one end of each of the four annular locking teeth is fixed to a whole to form a connecting portion, the number of the lock bodies 32 having the mounting holes is also four, the inner side wall of each of the lock bodies 32 is further provided with a mounting groove extending along the length direction, the mounting grooves are simultaneously communicated with the four mounting holes, and when the annular locking teeth are inserted into the corresponding mounting holes, the connecting portions of the locking tooth bodies 31 are located in the mounting grooves.

Of course, in practical applications, the number of the lock tooth bodies 31 is not limited to four, and the specific setting number thereof may be changed according to the specific application requirements.

Further, when the number of the locking tooth body 31 having the annular locking tooth is four, the inner locking edge 31a and the outer locking edge 31b are located at two ends of the locking tooth body 31, and the inner locking edge 31a and the outer locking edge 31b are not arranged at unique positions, for example, they can be arranged at the middle position of the locking structure 3, but arranged at two ends, so that the stability of the locking is better, which is a more preferable scheme.

Of course, the positions where the inner locking edge 31a and the outer locking edge 31b are arranged are actually related to the number of the locking tooth bodies 31, and when the number of the locking tooth bodies 31 is four, the inner locking edge 31a and the outer locking edge 31b are arranged at two ends of the locking structure 3, so that the stability is better; and when the quantity of latch tooth body 31 is eight or more, interior locking limit 31a and outer locking limit 31b set up in the middle part of locking structure 3 on the contrary, and stability is better.
