[0053] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0054] Example

[0055] See Figures 1 to 11 As shown, a lift-up deadbolt includes a bottom shell 1 and a top cover 2 fixed by a screw. A locking tongue 3 is provided between the bottom shell and the top cover. A movable frame 4 is provided inside the bottom shell. In this embodiment, the bottom shell, top cover, and locking tongue are all conventional structures of the prior art, so they are not described in detail. The movable frame is set inside the bottom shell and can move horizontally inside the bottom shell, thereby driving the locking tongue to extend and retract to achieve locking or unlocking.

[0056] In practical applications, two U-shaped brackets 5 are fixed to the bottom shell by screws, and the two U-shaped brackets are located inside the movable frame. During assembly, the end of the locking tongue is engaged with the movable frame and extends between the two U-shaped brackets. A return spring 6 is provided between the end of the movable frame away from the locking tongue and the inner wall of the bottom shell. During use, the return spring mainly resets the movable frame and drives the locking tongue to retract to achieve unlocking.

[0057] Furthermore, in practical applications, a deadbolt block 7 is provided within the movable frame, and the symmetrical edges of the deadbolt block can be raised and positioned within the U-shaped bracket. Additionally, an outer door handle structure 8 and an inner door handle structure 9 are provided between the bottom shell and the top cover. Both the outer and inner door handle structures have square handle mounting holes at their centers. During use, the rotation of the outer or inner door handle structure causes the movable frame to translate, which in turn causes the latch to translate, achieving locking or unlocking. In practical applications, the top cover has a separate inner door deadbolt structure, which is a conventional structure in existing technology and therefore not described in detail.

[0058] In practical applications, the outer door handle structure includes a rotating shaft 81, a toggle piece 82, and an unlocking component 85; the rotating shaft has an arc-shaped groove 83 in the middle of its symmetrical outer wall, and a vertical locking groove 84 located in the middle of the arc-shaped groove on the rotating shaft; the unlocking component is located on the outer surface of the rotating shaft; a protrusion 10 is fixed on the symmetrical inner wall of the toggle piece; and it also has an arc-shaped groove that cooperates with the vertical locking groove.

[0059] In practical applications, the anti-locking block includes a cross-shaped pressing block 71, a guide plate 72 integrally formed on the side end of the cross-shaped pressing block, and a stop block 73 located above the guide plate; during assembly, its rotating shaft is located in the recessed area of ​​the guide plate, and the actuating piece is located in the gap between the guide plate and the stop block.

[0060] In practical applications, an arc-shaped guide groove 11 is provided on the inner wall of the guide plate; a guide protrusion 12 is fixed on the bottom surface of the actuating piece; during operation, the actuating piece rotates, and the guide protrusion moves in the arc-shaped guide groove and is stopped at the groove wall of the arc-shaped guide groove.

[0061] In practical applications, an isolation plate 13 is provided between the outer door handle structure and the inner door handle structure, and a support block 14 is fixed to the end of the isolation plate; protruding strips 15 are fixed on the edges of both the isolation plate and the unlocking component; an arc-shaped protrusion 16 is provided on the top surface of the actuating piece, a recess is provided on the unlocking component, and a protrusion that mates with the recess is provided on the bottom surface of the support block, with the protrusion and recess engaging in a locking connection; protruding strips are fixed on the edges of both the isolation plate and the unlocking component; an arc-shaped protrusion is provided on the top surface of the actuating piece, a recess is provided on the unlocking component, and a protrusion that mates with the recess is provided on the bottom surface of the support block, with the protrusion and recess engaging in a locking connection.

[0062] See details Figures 6 to 11 As shown, during use, the protrusion of the isolating member engages with the concave part of the unlocking member, allowing them to rotate synchronously. When the isolating member and the unlocking member rotate, their protruding strips rotate, causing the protruding strips on the isolating plate to abut against the arc-shaped protrusion or the protruding strips on the unlocking member to abut against the guide protrusion. Therefore, under the action of the guide protrusion or the arc-shaped protrusion, the anti-locking block will rise and fall, causing the protrusion to enter the arc-shaped groove 83 or the vertical locking groove 84 of the rotating shaft 81, thereby realizing the rise and fall of the anti-locking plate, which presses against or disengages from the top surface of the lock tongue, realizing the anti-locking or unlocking operation. When it enters the arc-shaped groove, the actuating plate rotates freely. When it enters the vertical locking groove, the actuating plate can rotate synchronously with the rotating shaft, thereby realizing the unlocking or unlocking operation.

[0063] In practical applications, the side of the cross-shaped pressing block is provided with a transverse abutment hole, and a ball 17 and a spring 18 are provided in the transverse abutment hole; a number of abutment holes 19 are provided on one inner wall of the U-shaped bracket along the same vertical line; in use, the actuating piece is lifted and drives the cross-shaped pressing block to rise and fall, the ball of the cross-shaped pressing block is locked into one of the abutment holes under the action of the spring, and the end of the cross-shaped pressing block abuts against the end of the locking tongue for abutment and limitation.

[0064] In practical applications, V-shaped locking grooves 20 are provided on the symmetrical inner walls of the movable frame; V-shaped protrusions 21 are provided on both the outer and inner door handle structures; in this embodiment, when the outer or inner door handle structure rotates, the V-shaped protrusions engage with the V-shaped locking grooves and drive the movable frame to translate. Through the above structure, the effectiveness and reliability of the movable frame's translation are ensured by the V-shaped protrusions engaging with the V-shaped locking grooves and driving the movable frame to translate.

[0065] In practical applications, the cover is provided with two strip-shaped grooves 22; the latch is fixed with two protrusions 23; during operation, the latch moves horizontally and drives the protrusions to move horizontally and guide within the strip-shaped grooves.

[0066] In practical applications, U-shaped clearance grooves 24 are provided on the symmetrical sidewalls of the bottom shell; guide vertical blocks 25 are fixed on the symmetrical outer walls of the movable frame, and the V-shaped locking groove is located inside the guide vertical blocks; the movable frame moves within the bottom shell, and the guide vertical blocks move within the U-shaped clearance grooves and are limited by the groove walls of the U-shaped clearance grooves. This ensures the effectiveness and reliability of the movable frame's translation, making it highly practical.

[0067] The present invention has positive effects: the structure of the present invention is reasonably designed, and it is provided with a movable frame, a deadbolt block, an outer door handle structure and an inner door handle structure; and in use, the outer door handle structure rotates and the toggle piece is lifted to achieve deadbolt, which is convenient to operate, can reduce the number of deadbolt structures, which is conducive to reducing processing costs, assembly costs, and assembly efficiency, and also helps to improve the stability and reliability of use, and has strong applicability and good practicality.

[0068] Furthermore, the outer door handle structure includes a rotating shaft and a toggle piece; the rotating shaft has an arc-shaped groove in the middle of its symmetrical outer wall, and a vertical locking groove in the middle of the arc-shaped groove is provided on the rotating shaft; a protrusion is fixed on the symmetrical inner wall of the toggle piece; the protrusion of the toggle piece is located in the arc-shaped groove or the vertical locking groove. Through the above structure, the overall structure is simple, which is conducive to improving processing efficiency and assembly efficiency, convenient operation, strong applicability and good practicality.

[0069] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0070] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, these obvious variations or modifications derived from the essential spirit of the present invention still fall within the scope of protection of the present invention.
