Detailed Description

Referring to fig. 1 to 4, a sliding door lock, which is used in cooperation with a lock pin 10, includes a lock body 20 and a handle 30, the lock body is provided with a lock hole 21 capable of cooperating with the lock pin, the handle is slidably fitted on the lock body, the handle is provided with an elastic member 40, the elastic member is bent, the head end of the elastic member is connected with the handle, the tail end of the elastic member is pivoted on a fixed shaft 21, the fixed shaft is installed on the lock body, and the tail end of the elastic member is provided with a locking plate 41.

The clavicle pin is mounted on the doorframe, the lock pin 10 is provided with a step 11 which is matched with the lock plate, preferably, an annular groove 12 is arranged at the end part of the lock pin, and one side wall of the annular groove forms the step. When the door is locked and moved, the lock pin is inserted into the lock hole 21, the handle is pressed, the elastic piece is elastically deformed, the tail end of the elastic piece rotates around the fixed shaft, the lock plate is clamped into the annular groove, and the lockset is locked with the lock pin. Preferably, the elastic member is a steel sheet having elasticity.

The elastic member 40 is provided with an arc-shaped section 42 which semi-surrounds the locking hole 21. The handle is in the state of pressing, and the radius of arc section diminishes, leads to the tail end of elastic component to rotate certain angle around the fixed axle, and this rotation can drive the locking plate and rotate into the lockhole, and the block is in the annular groove of lockpin in the lockhole. At the moment, the handle locking device limits the handle to pop out of the lock body, the sliding door is in a locking state, and the elastic piece accumulates elastic potential energy. When the handle is actuated to enable the handle locking device to not limit the handle any more, the handle pops out of the lock body under the elastic potential energy of the elastic piece to enable the handle to reset. Therefore, the elastic piece has the functions of locking the sliding door and popping out the handle, and has simple structure and diversified functions.

The handle 30 comprises a stretching piece 31 and a handle body 32, the stretching piece is movably matched with the handle body, and the stretching piece can axially move relative to the handle body; a stop rod 33 is hinged on the handle body, an elastic part 34 is arranged on the left side of the stop rod, a limiting part 35 is arranged on the right side of the stop rod, the elastic part is installed on the handle body, the limiting part is movably matched on the handle body, and the limiting part is connected with the stretching part; the lock body is provided with a fixed block 22 which is positioned above the handle body. Initially, the top end of the stop rod is located at the left end of the fixed block, and when the handle is pressed, the handle is actually pressed on the stretching member, and the stretching member acts on the handle body, so that the whole handle extends into the lock body 20. In the process that the handle extends into the lock body, the top end of the stop rod is inclined due to the contact with the bottom surface of the fixed block, and the inclined stop rod is pressed against the elastic piece 34 to deform the elastic piece; when the top end of the stop rod moves to the right end of the fixed block, the stop rod resets under the action of the elastic piece, the top end of the stop rod is higher than the bottom surface of the fixed block, and the stop rod is limited by the limiting piece on the right side and cannot swing rightwards. When the handle body 32 is pulled out, the top end of the stop rod is pressed against the right end of the fixed block, the stop rod is limited by the limiting part on the right side, and at the moment, the locking plate 41 is clamped in the annular groove 12 of the locking pin. When the lock needs to be unlocked, the stretching piece 31 is pulled, the stretching piece drives the limiting piece, the limiting piece moves downwards, the stop rod can swing rightwards, therefore, the top end of the stop rod is lower than the bottom surface of the fixed block, and the handle can pop out of the lock body under the action of the elastic piece.

A guide groove 321 is formed in the handle body 32, the limiting piece 35 is matched in the guide groove, a spring 36 is arranged at the bottom of the guide groove, the top end of the spring is connected with the bottom of the limiting piece, and the top of the limiting piece protrudes out of the guide groove; the guide slot is arranged obliquely, the bottom of the limiting part is provided with a stay wire 37, and the stay wire is connected with the stretching part. The stretching piece is pulled out, the stretching piece moves axially relative to the handle body, the wire pulls the limiting piece, the limiting piece moves in the guide groove, the spring is compressed, and the stop rod 33 can swing right; and releasing the stretching piece, and enabling the limiting piece to ascend and reset under the action of the spring.

Preferably, the elastic member 34 is a rubber block having elasticity, and the rubber block is provided therein, compared to a spring, so that the service life thereof is longer.

The stretching piece 31 is provided with a stretching rod 311, the end part of the stretching rod is provided with an annular outer flange 312, the handle body 32 is provided with a blind hole 322, the end part of the blind hole is provided with an annular inner flange 323, the annular outer flange is matched in the blind hole, and the annular outer flange can be abutted against the annular inner flange. The annular outer flange moves in the blind hole, and when the annular outer flange is abutted against the annular inner flange, the relative displacement between the stretching piece and the handle body reaches the maximum. The pull wire is connected with the stretching rod, and a pull wire hole for the pull wire to pass through is formed in the handle body.

The handle body 32 is provided with a first cavity 324 for mounting the stop rod 33, the elastic member 34 and the limiting member 35. The right half part of the lock body 20 is provided with a second cavity 23 for installing the elastic element 40 and the fixed shaft 21; the left half of the lock body is separately provided with a sliding groove for cooperating with the pull handle 30.
