The spring 24 is disposed at the bottom end of the inner sliding groove portion 212, and both ends of the spring respectively act on the inner end surface of the inner sliding groove portion 212 and the corresponding end surface of the slider 22 (here, a spring counter bore is further disposed on the end surface), so that the slider always tends to slide toward the outside of the sliding groove.

When the utility model is used, the touch seat 1 and the locking seat 2 are respectively arranged on a door and the ground, when the door is closed, the enclosed opening 261 of the pair of rotary locking blocks 26 of the locking seat 2 is in an open state (figure 4), at the moment, the slide block 22 and the pair of rotary locking blocks 26 thereon are pushed by the spring 24, and the stressed outward swinging gear 262 of the rotary locking blocks 26 is blocked by the locking unlocking part 217 and is opened outwards; the movable hook part 232 of the hook 23 is separated from the hook position 221 of the slide block 22 and is positioned on a first plane c1 between the lower hook lower-swing inward-push surface 226 and the upper hook slide surface 227 at the lower end of the guide groove 222;

when opening the door, along with the staff drives the contact base 1 and moves toward tight lock base 2 direction when pushing the door, the touching head 111 of touching pole 11 enters into the spout of tight lock base 2 slider, and touching head 111 begins to act on slider 22 and makes it slide inwards after overcoming the effort of spring 24, and at this moment, the activity hook portion 232 of couple 23 is the motion in opposite directions with slider 22, then: on the one hand, when the movable hook 232 of the hook 23 slides upwards on the first plane c1, as mentioned above, because the right side has the third step b3 and the upper surface of the hook 23 is pressed by the spring wire 30, the end plane of the movable hook 232 is always tightly attached to the bottom surface of the guide slot 222, therefore, the movable hook 232 slides upwards leftwards along the third step b3 under the action of the edge of the third step b3, and enters the section of the guide slot where the hook upper sliding surface 227 and the hook upper sliding inner swinging pushing surface 228 are located to slide upwards; when the movable hook 232 of the hook 23 enters the upper end of the guide groove 222 and is under the action of the upper sliding inward swinging push surface 228 of the hook, the side surface is abutted against the upper swinging inward push surface 223 of the hook; meanwhile, the end face of the bottom of the movable hook 232 slides to the first step b1 from the first inclined plane a1 and jumps over the first step b1 at the bottom of the guide groove 222, and is tightly attached to the second plane c2 under the pressure of the spring wire 30, at this time, the hand releases the door, the slider 22 slides outwards a little under the thrust of the spring 24, and similarly, the movable hook 232 of the hook 23 slides downwards to the right along the edge of the first step b1 under the action of the first step b1 until the hook position 221 is hooked; on the other hand, when the sliding block 22 slides inwards along the inner sliding groove 212, the rotating locking block 26 is driven to slide towards the linear inner sliding groove 212 from the horn-shaped outer sliding groove 211, and under the acting force of the side wall of the linear sliding groove 212, the pair of rotating locking blocks 26 simultaneously swing inwards and are folded, when the pair of rotating locking blocks 26 slide into the linear inner sliding groove 212 from the horn-shaped outer sliding groove 211, the touch head 111 of the touch rod 11 can be tightly held, and thus the locking after the door is opened is completed.

When the door is closed, the door is pushed slightly inwards, the sliding block 22 slides slightly inwards through the touch head 111 of the touch rod 11, at this time, the movable hook 232 of the hook 23 leaves the hook position 221, the locking of the hook position 221 is released, the sliding block swings upwards and rightwards under the action of the hook swinging upwards pushing surface 224 and reaches the hook lower sliding surface 225, at this time, the movable hook 232 of the hook 23 reaches the upper end, under the action of the spring wire 30, the bottom end surface of the movable hook 232 slides through the second inclined surface a2 at the bottom of the guide groove 222 to the second step b2 section and jumps over the second step b2 at the bottom of the guide groove 222 and clings to the third plane c3, at this time, the hand is released, the sliding block 22 slides outwards under the action of the spring 24, the movable hook 232 enters the hook lower sliding surface 225 of the guide groove 222 and the hook sliding downwards swinging inwards pushing surface 226 along the edge of the second step b2, slides to the first plane c1 along the sliding inwards swinging inwards pushing surface 226, under the action of the spring wire 30, the bottom end surface of the movable hook 232 slides over the section from the third inclined surface a3 to the third step b3 at the bottom of the guide groove 222 and jumps over the third step b3 at the bottom of the guide groove 222 and is tightly attached to the first plane c 1; meanwhile, the slide block 22 drives the pair of rotary locking blocks 26 to slide outwards under the pushing force of the spring 24, when the pair of rotary locking blocks 26 slide into the horn-shaped outer sliding groove portion 211 from the linear inner sliding groove portion 212, the outer swing gears 262 of the rotary locking blocks are under the action of the respective locking block unlocking portions 217, the pair of rotary locking blocks 26 swing outwards and open respectively to release the locking of the touch head 111 of the touch rod 11, and the slide block 22 and the rotary locking blocks 26 are limited at the locking block unlocking portions 217, so that the door can be slightly pulled to close. Therefore, when the door is opened and closed once, the hook finishes the cycle process of sliding along the sliding groove while swinging.

From the above, except that the push type mechanical lock with the patent number of CN201720277545.6 is sucked, the advantage that it is very convenient and labor-saving to use when opening or locking the door, the structure of the mechanical locking mechanism is simpler, and the required parts are less, therefore, the utility model has the advantages of more reasonable and simple structure and lower production cost.

In this embodiment, the locking block unlocking portion 217 is an unlocking limit pin arranged in a root circular hole of the horn-shaped outer sliding groove portion 211, as shown in fig. 1 and 6, when the sliding block 22 slides into the linear inner sliding groove, the side wall of the linear sliding groove 212 acts on the rotary locking block 26, so that the rotary locking block 26 swings inwards and folds; when the sliding block slides from the linear inner sliding groove 212 to the horn-shaped outer sliding groove portion 211, the unlocking limit pin is just hooked on the forced outer swing gear 262 of the rotary locking block 26 to swing the locking block outwards, so that the purpose of unlocking is achieved. Of course, the deadlocking piece unlocking portion may be a touch piece or the like installed at the root of the outer slide groove portion 211, as long as the rotary deadlocking piece 26 can be swung outward to unlock when the slide block slides outward.

Preferably, a cover 29 is arranged outside the seat body 21, so that the locking seat can be more beautiful, and the cover can prevent dust, slag and the like on the ground from entering the interior of the seat body 21 and affecting the smooth sliding of the slide block 22; an opening 291 for allowing the touch head 111 of the touch lever 11 to enter and exit is formed in the housing.

Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications can be made therein without departing from the spirit and scope of the invention as defined in the appended claims. Therefore, the detailed description of the embodiments of the present disclosure is to be construed as merely illustrative, and not limitative of the present disclosure, but rather to limit the scope thereof by the appended claims.
