DETAILED DESCRIPTION

[0013] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Example

[0014] See Figures 1 to 6 As shown, a combined concealed lock comprises a bracket 1 provided with a lock cavity 11, and further comprises a movable member 2, a support 3, a movable lock member 4 and a plurality of connecting shafts 5 arranged in the lock cavity 11; In actual application, the support 3 is located at the bottom of the lock cavity 11 and is positioned and connected to the bracket 1 through two connecting shafts 5; the movable lock member 4 is located in the middle of the lock cavity 11 and is rotatably connected to the bracket 1 through the connecting shaft 5; the movable member 2 is located at the upper part of the lock cavity 11, and one end of the movable member 2 is riveted to the bracket 1 and can rotate at the riveted position; A torsion spring 8 with a reset and spring-pressing function is provided at the connection between the movable locking member 4 and the bracket 1; a limiting protrusion 6 for blocking the range of motion of the movable locking member 4 is provided at the top of the support 3. The range of motion of the movable locking member can be limited by the limiting protrusion to prevent the transition of motion and improve the stability of use. A reset spring 7 is provided at the connection between the movable member 2 and the bracket 1; a locking hook 9 is fixed at the bottom of the movable member 2; the movable member 2 is arranged in a triangle and the locking hook 9 is at the bottom vertex of the triangle.

[0015] The movable part 2 is locked or unlocked by the locking hook 9 when it is engaged or disengaged from the movable locking part 4. A pillar 41 and a spring protruding mounting bayonet 42 are provided on one side of the movable locking part 4, and an introduction track line 43, a limit stopper 44, a stopper 45 and an output track surface 46 are provided on the other side of the movable locking part 4; one end of the force-bearing torsion spring 8 is engaged and positioned on the spring protruding mounting bayonet 42, and the pillar 41 can be engaged and positioned on the side wall of the lock cavity 11; when the movable part 2 moves, it moves on the introduction track line 43 and is limited by the guide limit stopper 44, and at the same time, the locking hook 9 of the movable part 2 is engaged and positioned with the stopper 45 under the action of the reset spring 7; when the movable part 2 is unlocked, it moves and resets from the output track surface 46. The output track surface 46 is an inclined surface from low to high, and the stopper 45 is L-shaped.

[0016] When it works, the movable part is pressed, and the locking hook 9 on the movable part 2 reaches the limit stopper 44 along the introduction track line 43 of the movable lock fastener 4. At this time, the downward pressure of the movable part 2 reaches the limit. When the movable part 2 is released, the movable lock fastener 4, under the action of the torsion spring 8, makes the locking hook 9 of the movable part enter the locking stopper 45 of the movable lock fastener 4 to realize the locking positioning, that is, the locking state of the concealed lock is realized; When the locking column is in the state, the movable part 2 is pressed down again, and the locking hook 9 slides from the L-shaped inner side of the blocking block 45 into the guide track surface 46. While moving along the guide track surface 46, the locking hook 9 also pushes the movable locking part 4 to the other side to achieve the release effect, that is, to achieve the open state of the concealed lock.

[0017] The structure of the present invention is reasonably arranged. It not only has a simple internal structure, which is beneficial to reducing processing and maintenance costs, but also is more convenient to assemble. At the same time, it can greatly increase the number of opening and closing times, increase the service life, and can be well positioned and locked, making it stable and reliable, with strong applicability and good practicality.

[0018] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural components recorded in the specification can also be directly processed according to existing technical common sense. At the same time, the connection method of each component adopts the mature conventional means in the prior art, and the machinery, parts and equipment all adopt the conventional models in the prior art, so no specific description will be given here.

[0019] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. However, these obvious changes or modifications derived from the essential spirit of the present invention still fall within the protection scope of the present invention.
