[0028] The present invention further includes a pin block, a lock tongue is provided with an inclined surface, and the pin block is provided with an inclined surface that is relatively consistent with the lock tongue. When the inclined surface of the lock tongue is subjected to a top pressure force on the inclined surface of the pin block that is on the same vertical line, the lock tongue can slide toward the inside of the inclined surface to the lock hole that is separated from the base. The button seat is provided with a sliding hole, and the pin block passes through the sliding hole of the button seat by a screw to install the button seat in the lock cavity of the sliding button, and the pin block and the inclined surface of the lock tongue form a top contact structure. The structure that can be adopted is that screw holes are provided in the lock cavity of the pin block and the sliding button, and the screws pass through the screw holes of the pin block, the sliding holes of the button seat, and the screw holes of the sliding button in sequence for connection and installation. At this time, the sliding hole of the button seat provides a certain distance of up and down movement space for the screw.

[0030] In the utility model, the rod seat, the slide seat and the button seat are provided with synchronization holes, and the rod seat, the slide seat and the button seat are connected by screws through the synchronization holes, so that the rod seat, the slide seat and the button seat form a connection structure that slides upward or downward synchronously, and the button seat is arranged in the lock cavity of the slide button, thus forming a synchronous linkage structure among the rod seat, the slide seat, the button seat and the slide button.

[0031] In the utility model, the slide is provided with a bayonet, and a silent block is installed on the slide through the bayonet. The bottom of the silent block is set to a shape that is mutually locked with the bayonet, so that the silent block can be installed on the slide. The silent block can be made of a rubber block, which has a better silent effect. When the slide slides up or down in the sliding cavity of the base, the silent block collides with the top and bottom of the sliding cavity, thereby achieving a better silent effect.

[0032] In the utility model, the base is provided with a mounting hole, and the base is mounted on the door frame by screws through the mounting hole.

[0033] In the utility model, the slide seat and the button seat are provided with connecting holes, and the slide seat and the button seat are connected and installed through the connecting holes. The connecting holes can be threaded holes, and the slide seat and the button seat can be connected and installed by screws through the connecting holes.

[0034] The present invention also includes a lock block, which forms a blocking structure for the lock rod. In a preferred embodiment of the lock block structure, the side of the lock block is a planar structure, which forms a block for the lock rod. The top of the lock block is a mounting surface, and the lock block can be installed on the upper door frame through the top mounting surface. In the first embodiment of the lock block and the lock rod being locked together, a pin hole corresponding to the lock rod is provided at the closed end of the door body on the upper door frame to form a locking structure, and the lock rod is inserted into the pin hole to form a locking structure. In the second embodiment of the lock block and the lock rod being locked together, a lock block is provided at the closed end of the door body on the upper door frame to form a block for the lock rod through the lock block.

[0035] How it works:

[0036] It should be noted that, in order to describe the technical solution and usage principle of the present invention in more detail, the attached drawings also include an upper door frame, a door body frame, and a cover plate. The lock stop is installed on the upper door frame at the closed position of the door body. A corresponding cavity structure is provided inside the door body frame. The rod seat and the lock rod are installed in the cavity structure, and then the door body frame is sealed by the cover plate. The lock rod can form a connection structure with the rod seat, or a rod groove for the lock rod to slide up and down can be provided through the door body frame. The rod groove is used for the installation and up and down sliding of the lock rod. The following description uses the structure in which the lock rod is installed in the rod groove. Corresponding mounting openings for the base and the lock seat need to be provided on the door body frame. The base and the lock seat are installed through the mounting opening. The door and window structure is very easy to understand, and it also belongs to the prior art. It can also be obtained by attaching Figure 6-7 No detailed structural description is required to understand.

[0037] When locking is required, the sliding button is pushed upward, and the lock tongue slides to the lock hole. The lock tongue is no longer subjected to the top force of the contact surface with the base, and the lock tongue is elastically pressed by the spring and inserted into the lock hole. The lock tongue and the bottom of the lock hole form a locking structure, and the sliding button cannot slide downward. The lock base is in a locked state on the base. At this time, the lock rod is pushed upward by the rod base and slides to the side of the lock block. The lock block forms a horizontal block for the lock rod, and the door body cannot be opened, thus forming a locked state;

[0038] When the lock needs to be unlocked, it is only necessary to push the sliding button downward with a certain force. When the sliding button needs to slide downward due to the pushing force, the lock tongue and the bottom of the lock hole form a locking structure. The rod seat, the sliding seat and the button seat are connected by a screw through the synchronous hole. The button seat is arranged in the lock cavity of the sliding button, so the rod seat, the sliding seat and the button seat cannot continue to slide downward. At this time, the pin block passes through the sliding hole of the button seat by the screw to install the button seat in the lock cavity of the sliding button, and the pin block and the inclined surface of the lock tongue form a top contact structure. The sliding hole allows the sliding button and the pin block to continue to slide downward, and the inclined surface of the pin block The surface presses the inclined surface of the lock tongue until the lock tongue moves in the opposite direction of the lock hole. When the lock tongue has not yet separated from the lock hole of the base, the button seat is at the topmost position in the lock cavity. When the lock tongue separates from the lock hole of the base, since the button seat is arranged in the lock cavity of the sliding button and the button seat has residual space for up and down movement in the lock cavity, the lock rod, rod seat, sliding seat and button seat generate downward gravity to make the button seat continue to slide downward for a distance, and the contact surface between the lock tongue and the base forms a top stop. At the same time, the lock rod is no longer subjected to the upward push of the rod seat. The lock rod slides downward due to its own weight until it separates from the lock stop to form an unlocked state.

[0039] The structure of the door and window sky lock of this utility model is more convenient to use. The locking state can be achieved by pushing the sliding button upwards, and the unlocking state can be achieved by pushing the sliding button downwards. Only the base and the sliding button are located outside the door frame, and the other structures are hidden in the cavity structure of the door frame, which is more concealed and beautiful.

[0040] The above embodiments are preferred embodiments of the present invention. All structures similar to those of the present invention and equivalent changes made thereto should fall within the scope of protection of the present invention.
