As shown in fig. 1, 9 and 10, the bolt 2 is L-shaped, and includes an engaging portion 2-1 and a fixing portion 2-2, the engaging portion 2-1 is vertically connected to the fixing portion 2-2, an opening is disposed at a middle position of an end of the engaging portion away from the fixing portion, and three through holes are disposed at an end of the fixing portion 2-2 away from the engaging portion, and the three through holes are distributed in a triangular shape, so as to be conveniently fixed to the door frame by screws.

It can be understood that, as shown in fig. 11, the latch bolt can be disposed inside the fixed doorframe in consideration of the aesthetic property of the lockset arrangement, wherein the fixed portion is disposed perpendicular to the fixed doorframe, and the engaging portion 2-1 is located at the middle position of the fixed doorframe in contact with the sliding door.

As shown in fig. 1-6, the lock core comprises a first limiting plate 1-1 and a second limiting plate 1-2 which are arranged in parallel, the first limiting plate and the second limiting plate are arranged below a top plate of the lock box cover and between two side plates, the limiting plates are connected with the lock box cover through a backing plate 6, a first backing plate is arranged at one end, away from the lock tongue, of the first limiting plate and the second limiting plate, a second backing plate is arranged at one side, away from the first limiting plate, of the second limiting plate, the first backing plate and the second backing plate are identical in shape and structure, and the length of the backing plate is equal to the width of the limiting plates.

The width of backing plate is less than the length of limiting plate to it is fixed with the roof of lock lid that first limiting plate, first backing plate, second limiting plate, second backing plate pass through the mounting, and the corresponding position also is equipped with the screw on the roof of lock lid, all sets up four through-holes on first limiting plate, second limiting plate, the backing plate 6, realizes being connected of lock core 1 and lock lid through the screw.

One end of the first limiting plate 1-1 is provided with a protruding portion 1-3 towards the second limiting plate, the protruding portion 1-3 is used for being clamped and connected with an opening in a spring bolt passing through the space between the first limiting plate and the second limiting plate, one side, close to the spring bolt, of the protruding portion 1-3 is connected with the first limiting plate, the remaining portion is separated from the first limiting plate, the protruding portion protrudes towards the second limiting plate, and the protruding portion is rectangular and is matched with the opening of the clamping portion in shape.

The center of one side, away from the first limiting plate, of the protruding portion is provided with fixing columns 1-4, the spring 3 is sleeved on the outer side of the fixing columns, one end of the spring 3 is connected with the protruding portion on the first limiting plate, and the other end of the spring abuts against the top plate of the lock box cover. When the lock core was close to the spring bolt, the space between first limiting plate and the second limiting plate was passed through to block portion tip, and the tip of block portion promotes the bellying, and when opening and the bellying coincidence in the block portion, under the elastic action of spring, the bellying fell into the opening, accomplished the joint of lock core and spring bolt, and the locking is accomplished to the tool to lock this moment, and the sliding door is closed.

Furthermore, two sides of one end, far away from the boss, of the first limiting plate are provided with connecting plates 1-5, two first connecting holes are formed in the connecting plates, the length of each connecting plate is smaller than that of each limiting plate, and one end, close to the boss, of each connecting plate is located on the left side of the boss 1-3. Set up the second connecting hole on the curb plate, first connecting hole through the connecting plate cooperates the second connecting hole, is convenient for further realize being connected of first limiting plate and lock lid curb plate.

In order to facilitate the spring bolt to pass through the space between first limiting plate and the second limiting plate, first limiting plate and second limiting plate are close to spring bolt one end and outwards buckle the setting in order to form V type opening.

After the lock cylinder is locked with the lock tongue, when a door needs to be opened, as shown in fig. 1-6, one side, away from the protruding portion, of the second limiting plate 1-2 is in sliding fit with the key 5, the key is U-shaped, two end portions of the key abut against the first limiting plate 1-1, the key is arranged on the second limiting plate and close to the lock tongue, the protruding portion is located between two abutting points of the key and the first limiting plate, taking fig. 4 as an example, the lock tongue 2 and the lock cylinder 1 are locked, when the door is opened, the key 5 is pressed downwards, the key 5 pushes the left end of the first limiting plate, due to the fact that the right end of the first limiting plate is fixed, the first limiting plate bends downwards to drive the protruding portion to move downwards, the spring is compressed, at this time, the protruding portion is separated from an opening in the clamping portion, the locking is released, then the sliding door is pushed rightwards, the lock tongue is separated from the lock cylinder, the door is opened, and after the key 5 is loosened, the first limiting plate and the protruding portion are restored to a natural state under the action of the spring 3.
