Referring to fig. 1 and fig. 2, a structure of a latch device according to an embodiment of the present invention will be described in detail.

The utility model discloses a spring bolt device that can pop out mainly includes following part: the bolt assembly 1, the locking mechanism 2, the release mechanism 3 and the first elastic element (not shown in the figure).

The utility model discloses a spring bolt subassembly 1 has included spring bolt 11, guide bar 12 and limit structure. Spring bolt 11 and limit structure set up respectively at the both ends of guide bar 12, spring bolt 11 sets up the front end at guide bar 12, limit structure adopts a sliding plate 13 in this embodiment, this sliding plate 13 sets up the rear end at guide bar 12, guide bar 12 should be less than the size of sliding plate 13 towards guide bar 12 one side in radial direction, that is to say, sliding plate 13 can bulge in the periphery of guide bar 12, make things convenient for locking mechanism 2 to support sliding plate 13 towards guide bar 12 one side with spring bolt 11 shrink in lock shell 4, in other embodiments, limit structure also can adopt and let guide bar 12 rear end 90 degrees buckle, form a part of bulge in the guide bar periphery, also can carry on spacingly with locking mechanism 2 cooperation. The limiting device 43 is further arranged in the lock case 4, the guide rod 12 penetrates through the limiting device 43, the limiting device 43 limits the guide rod 12 to move along the axial direction of the guide rod, namely, the lock tongue 11 is limited to move along the axial direction of the guide rod 12, in the embodiment, the limiting device 43 adopts two limiting columns, one limiting point can be formed by the two limiting columns, then the lock hole corresponding to the lock tongue 11 in the lock case 4 can form another limiting point, and the two limiting points limit the lock tongue assembly 1 to move in the axial direction of the guide rod. The first elastic element of this embodiment is a spring, which is disposed between the position-limiting device 43 and the rear end of the latch bolt, and when the latch bolt assembly 1 is retracted into the lock housing 4, the spring is compressed, and generates an elastic force along the spring-out direction of the latch bolt. In other embodiments, the spring may be replaced by a spring plate and arranged at the corresponding position according to the characteristics of the spring plate. The bolt is the oblique bolt in this embodiment, in other embodiments, can also adopt other existing bolts such as cross bolt. The limiting device 43 can also adopt other structures such as a limiting ring and the like for limiting besides the limiting column.

The utility model discloses a locking mechanism 2 is used for restricting, locking spring bolt (spring bolt subassembly) in lock shell 4, and locking mechanism 2 is located spring bolt subassembly 1's right side in the picture, and locking mechanism 2 has adopted a locking arm (also can be called the locking plate), and the one end that this locking arm is close to the spring bolt rotates with the lock shell to be connected, the utility model discloses the hinged end is called with this end, and the free end is called to the other end, is equipped with a bayonet socket 22 on the free end, and bayonet socket 22 and sliding plate 13 are towards the one side looks butt of guide bar to lock spring bolt subassembly 1, restrict in the lock shell. The left side of the locking arm between free end and hinged end is equipped with an arc breach, driving lever 42 links with the actuating mechanism of tool to lock, its orientation towards the arc breach extends one and has the tip of chamfer with the arc breach mutually supporting, when unlocking tool such as key unblanks, actuating mechanism moves, the tip that drives driving lever 42 moves along the direction of arc breach towards the picture below, thereby drive the direction motion of locking arm towards the picture below, because the bayonet socket 22 butt of free end is on the sliding plate, can drive the direction motion of spring bolt subassembly 1 towards the picture below like this, spring bolt 11 contracts to in the lock shell 4, the tool to lock is the state of unblanking. A projection 21 is also provided on the hinged end of the locking arm, in this embodiment the projection 21 is spatially perpendicular to both its axis of rotation and the guide bar, the projection 21 being part of the structure of the automatic pop-up latch which will cooperate with the release mechanism 3, the first resilient member, to automatically release the latch 11.

The utility model discloses a release mechanism 3 has specifically included an actuating arm 32 that has free end and butt end 33, this actuating arm 32 is parallel to each other with guide bar 12, its free end is located same end with spring bolt 11, the partly of free end can stretch out outside lock shell 4 with spring bolt 11 is the same, the free end is closed one side towards the door body and is opened one side towards the door body and all carries out the chamfer and handle, butt end 33 is connected with lock shell 4 through the second elastic component, still be equipped with the poker rod (not shown in the figure) that links with locking mechanism 2's arch 21 on the actuating arm between free end and the butt end. When the door body is closed, the free end is pressed by the door frame and moves towards the inside of the lock shell 4 like the bolt 11, so that the release mechanism 3 is contracted in the lock shell 4, and at the moment, the second elastic element (a spring is adopted in the embodiment) is compressed to generate elastic force towards the free end. When the door body is opened, because there is not the suppression external force of door frame, under the effect of second elastic component elasticity, the free end moves outside lock shell 4, and the poker rod moves outside lock shell 4's direction promptly, stirs arch 21 for the locking arm rotates around its axis of rotation, and the bayonet socket of the free end of locking arm loosens sliding plate 13, and spring bolt subassembly 1 also moves outside lock shell 4's direction under the effect of first elastic component's elasticity, pops out spring bolt 11 automatically.

In order to avoid that the release mechanism 3 will not deviate from the axial movement direction when it is retracted into the lock housing 4, the present invention provides a stop block 31 at the free end of the driving arm 32, and accordingly, a stop portion for limiting the stop block 31 from completely entering the lock housing is also required to be provided in the lock housing 4. In this embodiment, the driving arm is disposed at a side of the lock case 4, the limiting block 31 is disposed at a side of the driving arm facing the side, a notch 41 is disposed at a corner of the side of the lock case 4 facing the limiting block 31 to form a blocking portion, when the driving arm moves toward the inside of the lock case, the limiting block moves to the notch 41 to limit the driving arm to further move toward the inside of the lock case, so that a small portion of the free end of the driving arm always protrudes slightly from the lock case 4, and the driving arm cannot completely fall into the lock case 4, resulting in shifting the axial movement direction thereof.

Besides the above-mentioned spring bolt device, the tool to lock that has adopted above-mentioned spring bolt device also belongs to the protection scope of the utility model.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
