This allows the flap lock 100 to have a locked state and an unlocked state.

In the operation process, the flap lock 100 can be triggered to switch between two states by pressing the button 130, so that the operation is simpler and more convenient; meanwhile, since the lock piece 120 and the button 130 have a tendency to rotate in the same direction in the process of being rotatably connected to the lock body 110, when the flap lock 100 is in the unlocked state, the lock piece 120 continues to rotate in the first direction after being disengaged from the button 130, and extends out of the opening 111 for operation. When the flap lock 100 is in the locked state, the button 130 is engaged with the lock block 120, and the lock block 120 can limit the rotation of the lock block 120 by the action of the rotation tendency of the button 130 under the engagement action of the button 130, that is, the rotation of the lock block 120 relative to the lock body 110 can be limited by the engagement of the button 130 with the lock block 120, overcoming the action of the rotation tendency of the lock block 120, and the locked state of the flap lock 100 can be maintained.

Therefore, the flap lock 100 can lock and unlock the flap lock 100 through the cooperation between the structures, the number of the structures is small, the cooperation between the structures is simple, the difficulty of manufacturing and assembling can be effectively reduced, and the cost can be reduced.

Referring to fig. 1-3, when the lock block 120 and the button 130 are installed, in order to rotatably connect the lock block 120 and the button 130 with the lock body 110, the door lock 100 further includes a first mounting bracket 140 and a second mounting bracket 150, and the first mounting bracket 140 and the second mounting bracket 150 may be integrally formed with the lock body 110. The button 130 is rotatably coupled to the first mounting bracket 140 and the locking piece 120 is rotatably coupled to the second mounting bracket 150.

The first mounting bracket 140 and the second mounting bracket 150 are connected to one side of the lock body 110 in a penetrating direction of the opening 111, and the first mounting bracket 140 and the second mounting bracket 150 are spaced apart from each other; therefore, the first mounting bracket 140 and the second mounting bracket 150 are arranged on one side of the opening 111 of the lock body 110, so that the connection between the lock block 120 and the button 130 and the rotation part of the lock body 110 is located on one side of the lock body 110, and in the installation and use process of the flap lock 100, the rotation connection structure can be arranged on the inner side of the lock body 110 through the lock body 110, so that the rotation connection structure is prevented from being exposed, and the use stability of the flap lock 100 can be improved.

Meanwhile, please refer to fig. 1-7, fig. 6 and 7 show the structure of the lock block and the button according to the embodiment of the present invention. Based on the above-mentioned arrangement of the first mounting bracket 140 and the second mounting bracket 150, the button 130 of the flap lock 100 further includes a pressing portion 131 and a rotation connecting portion 132 connected to the pressing portion 131. Wherein, the rotary connecting part 132 is rotatably connected with the first mounting bracket 140; the locking block 120 includes a first section 121 and a second section 122, and the second section 122 is rotatably connected to the second mounting bracket 150.

In addition, in order to prevent the internal structure of the flap lock 100 from being exposed to the outside by closing the opening 111 through the engagement between the locking piece 120 and the button 130 when the flap lock 100 is in the locked state, the opening 111 may include a first partition 112 and a second partition 113, the first partition 112 may have a shape corresponding to the pressing portion 131, and the second partition 113 may have a shape corresponding to the first partition 121; thus, when the flap lock 100 is in the locked state, the first section 112 engages with the pressing portion 131, and the second section 113 engages with the first section 121, so that the opening 111 can be closed.

It should be noted that, when the flap lock 100 is in the unlocked state, the engagement between the lock block 120 and the button 130 is lost, and at this time, the lock block 120 is rotated in the first direction by its own rotation tendency and extends out of the opening 111, and the length of the first partition 112 is smaller than the length of the second partition 113 in the extending direction of the opening 111. So that the length of the first section 121 engaged with the second section 113 is greater than the length of the button 130 engaged with the first section 112, thereby facilitating the operation by increasing the length of the portion of the locking piece 120 that protrudes out of the opening 111 in the unlocked state.

Further, referring to fig. 6 and fig. 7, in the present embodiment, the button 130 further includes a limiting portion 133, the limiting portion 133 is connected to one end of the pressing portion 131 away from the locking block 120, and the limiting portion 133 is used for abutting against the lock body 110 to limit the rotation of the button 130 along the first direction; the lock block 120 further includes a third section 124, the third section 124 is connected to the second section 122, and the third section 124 is configured to abut against the lock body 110 to limit rotation of the lock block 120 in the second direction.

Therefore, the rotation of the button 130 in the first direction is limited by the limiting part 133, and the purpose of the limiting part is to limit the button 130 which rotates to the locking position, namely the button 130 can be ensured to be in the locking position under the action of the self rotation trend without receiving the external force; the third part 124 of the locking piece 120 abuts against the lock body 110 to limit the rotation of the locking piece 120 in the second direction, so as to prevent the locking piece 120 from being locked with the button 130 in the locked state, or the locking piece 120 moves in the second direction under the action of external force until the locking piece moves to the locked position where the locking piece can be locked with the button 130, and further movement of the locking piece 120 in the second direction is limited, that is, the movement of the locking piece 120 in the second direction can be limited at the locked position through the limiting function of the third part 124, so as to maintain the locked state; and the movement of the two structures in different directions is limited by the limiting part 133 of the button 130 and the third part 124 of the lock block 120, so as to facilitate the movement of the button 130 to the locking position, and the movement of the lock block 120 to the locking position is driven by external force, thereby facilitating the locking of the flap lock 100. Note that the second direction is opposite to the first direction. Therefore, when the first direction is clockwise, the second direction is anticlockwise; when the first direction is counterclockwise, the second direction is clockwise.

In addition, the lock block 120 further includes a trigger subsection 125, the trigger subsection 125 being connected to an end of the third subsection 124 remote from the button 130; the trigger subsection 125 is adapted to cooperate with an external structure to provide the flap lock 100 with a locked state and an unlocked state relative to the external structure.

In order to maintain the locked state of the flap lock 100, the present invention adopts a mode that the directions of the rotation trends of the lock block 120 and the button 130 are the same, and the lock block 120 is engaged with the button 130; based on the above arrangement, in order to facilitate the mutual engagement between the first section 121 and the pressing section 131, a locking groove 123 may be provided at one end of the first section 121 close to the pressing section 131, and the locking groove 123 is used for engaging with the button 130. Thus, when the flap lock 100 is in the locked state, the engaging groove 123 engages with the button 130 to maintain the locked state of the flap lock 100.

It should be noted that, when the flap lock 100 in the unlocked state is locked, the lock block 120 may be driven to rotate in the second direction under the action of an external force, that is, the lock block 120 is driven to rotate to the locking position where the button 130 is engaged with; at this time, when the lock piece 120 and the button 130 are contacted for the first time, in order to facilitate the mutual matching of the lock piece 120 and the button 130, an arc-shaped surface is arranged on the surface of the lock piece 120 contacted with the button 130 for the first time, so that in the process that the lock piece 120 rotates along the second direction, the button 130 is pushed to move along the second direction through the arc-shaped surface, when the lock piece 120 moves to the position of the clamping, the effect of pushing the button 130 to rotate along the second direction disappears, and at this time, the lock piece 120 is clamped with the button 130, so that the locking state of the flap lock 100 is achieved.
