Description

Technical Field

[0001] The utility model relates to the technical field of door locks, in particular to a door handle anti-lock switch structure. Background Art

[0002] Most common indoor door locks (such as bedroom doors, toilet doors, balcony doors, etc.) include an inner handle, an outer handle, a lock box, a square shaft, and an anti-locking component;

[0003] The applicant has applied for a bathroom door handle with a long service life with application number "202420199835.3", which includes a square bar, an inner panel and an outer panel. The inner panel is rotatably connected to an inner handle, and the outer panel is rotatably connected to an outer handle. One end of the square bar is linked to the inner handle, and the other end is linked to the outer handle. The outer handle is provided with an anti-locking component, which includes a rotating seat assembly, a sliding seat and a knob. The rotating seat assembly includes a first rotating seat and a second rotating seat. The second rotating seat is sleeved on the end of the first rotating seat away from the square bar; a linkage structure is provided between the first rotating seat and the second rotating seat;

[0004] However, most of the door handles in the above documents and on the market currently use knobs for anti-locking. The knob switch is often set outside the inner panel and exposed to the external space, which makes the knob body very easy to be damaged and cause malfunction, thereby affecting normal anti-locking and unlocking, and also causes the exposed knob to occupy a larger external space. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide a hidden switch and a door handle anti-lock switch structure which occupies a small external space in view of the deficiencies of the above-mentioned prior art.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a door handle anti-lock switch structure, comprising a square bar, an inner panel and an outer panel installed on a door body, the inner panel being rotatably connected to an inner handle, the outer panel being rotatably connected to an outer handle, one end of the square bar being linked with the inner handle, and the other end being linked with the outer handle, the outer handle being provided with an anti-lock component for locking the outer handle with the base of the outer panel, the inner handle comprising a shell, characterized in that: a rotating body capable of being linked with the anti-lock component so as to enable the anti-lock component to be locked or unlocked with the outer panel is provided in the shell, a sliding member capable of reciprocating along the shell toward or away from the rotating body is provided in the shell, a toggle switch extending toward the outside of the shell is provided on one side of the sliding member, and a linkage structure capable of causing the rotating body to rotate is provided between the sliding member and the rotating body.

[0007] The above-mentioned technical scheme is adopted: compared with the prior art which mostly adopts the knob assembly for anti-locking, the utility model adopts the setting of the sliding part and the linkage structure. When anti-locking is needed, it is only necessary to slide the toggle switch to drive the sliding part to move up and down, and the linkage structure is used to drive the rotating body to rotate, so as to link the anti-locking assembly, so that the anti-locking assembly can be locked with the outer panel to realize the anti-locking function. When unlocking is needed, it is only necessary to slide the toggle switch in the opposite direction.

[0008] The utility model is further configured as follows: the linkage structure comprises a gear connected to one end of the rotating body away from the inner panel and a rack located at the top of the sliding member and extending toward the rotating body; the rack and the gear mesh with each other; and a sliding groove for the sliding member to slide is provided in the shell.

[0009] The above technical solution is adopted: the rack and the gear are meshed with each other for transmission, so that when the sliding part moves up and down, the rack is driven to move up and down, and the gear is linked to rotate. Since the gear is connected to the rotating body, it can drive the rotating body to rotate, thereby linking the anti-locking component on the external handle and the outer panel to lock or unlock.

[0010] A further configuration of the utility model is: a limit groove is provided on the sliding member, a limit column is provided on the shell, and the limit column is located in the limit groove; a limit flange is provided on one end of the rotating body located near the inner panel of the gear, a first limit block is provided on the top of the limit flange, and a second limit block is provided on the shell near the first limit block, and the two can offset each other.

[0011] The above technical solution is adopted: through the setting of the limit groove and the limit column, the sliding distance of the sliding member can be limited when the sliding member slides up and down; at the same time, through the setting of the limit flange and the first and second limit blocks, when the rack drives the gear to rotate, the rotation angle of the gear can be limited to ensure the transmission effect.

[0012] The utility model is further configured as follows: a fixed block is provided on one side of the sliding member, at least two arc grooves capable of engaging with the fixed block are provided on the housing near the sliding groove, and the arc grooves are distributed at intervals, and a yield groove is provided on the sliding member near the fixed block.

[0013] The above technical solution is adopted: through the setting of the fixed block and the arc groove, the preferred fixed block is semicircular, which cooperates better with the arc groove. During use, under normal conditions, the fixed block is located in the arc groove below and is locked and fixed to ensure that the sliding part does not move. When the user slides the toggle switch upward to reverse lock, the sliding part moves upward at this time. Due to the setting of the give way groove, the fixed block is squeezed with the arc groove during the upward movement. At this time, the fixed block can move in the direction of the give way groove, so that the fixed block can move upward over the arc groove. When it moves to a certain position, the fixed block enters the arc groove above and is locked and fixed with the arc groove. When reverse locking is achieved, the sliding part can not slide downward, thereby ensuring the reverse locking effect.

[0014] A further configuration of the utility model is that an opening is provided on the shell for the toggle switch to pass through, and the toggle switch can reciprocate along the opening, and the opening is arranged on a side of the shell close to the inner panel, and at a position where a person holds the toggle switch, the toggle switch is located on a side of the sliding member close to the inner panel.

[0015] The above technical solution is adopted: by setting an opening, and the opening is set on the side of the inner handle housing close to the inner panel, that is, the side facing the door, and the toggle switch is also set on the side of the sliding member close to the inner panel, so as to realize the hidden function of the anti-lock switch, and at the same time can improve the coordination and aesthetics of the handle, and the toggle switch can move back and forth along the opening, so that the user only needs to slide the toggle switch up and down to drive the sliding member to slide up and down, thereby linking the rack, gear, rotating body and other components to unlock and lock.

[0016] A further arrangement of the utility model is that the anti-locking assembly includes a rotating seat rotatably installed inside the outer handle, and a sliding seat coaxially rotating with the outer handle; a locking surface, an unlocking surface, and a guide surface connecting the locking surface with the unlocking surface are provided on one end of the sliding seat close to the rotating seat; there is a height difference between the locking surface and the unlocking surface along the axis direction of the rotating seat; the rotating seat is provided with a structure adapted to the locking surface, the guide surface, and the unlocking surface; and the sliding seat is also linked to a reset member.

[0017] By adopting the above technical solution, the anti-locking function can be realized by only setting a rotating seat and a sliding seat in cooperation with a toggle switch. The sliding toggle switch drives the rack and the gear to be linked, so that the rotating body rotates and the rotating seat is linked to rotate. Under the action of the rotating sliding structure (i.e., the locking surface, the guide surface, and the unlocking surface respectively arranged on the rotating seat and the sliding seat), the sliding seat moves to be connected with the outer panel (this can be achieved by setting a card block on the sliding seat and a card slot on the outer panel; when the card block is inserted into the card slot, the sliding seat is connected to the outer panel; when the card block is separated from the card slot, the sliding seat is separated from the outer panel). Since the outer handle and the sliding seat are in a coaxial rotation relationship, the outer handle is locked along with the sliding seat to realize anti-locking. The operation for unlocking is also relatively simple, and the toggle switch can be slid in the reverse direction.

[0018] The utility model is further configured as follows: a driving plate is detachably and fixedly connected to one end of the rotating body close to the square bar, the other end of the driving plate is linked to the rotating seat, and a clearance through hole is provided in the square bar for the driving plate to pass through.

[0019] By adopting the above technical solution: through the setting of the driving plate, the transmission effect between the rotating seat and the rotating body can be further improved. At the same time, a clearance hole is provided in the square bar so that the driving plate can rotate through the square bar to link the rotating body and the rotating seat with each other without affecting the operation of the square bar.

[0020] A further configuration of the utility model is that a plurality of support columns are provided along the inner wall at one end of the outer handle away from the outer panel and at one end of the inner handle away from the inner panel, a mounting plate is provided on the support columns, a cover plate is provided on the mounting plate, a plurality of mounting grooves are provided on the mounting plate, and a plurality of mounting buckles corresponding to the mounting grooves are provided on one side of the cover plate close to the mounting plate.

[0021] The above technical solution is adopted: the arrangement of the support column facilitates the assembly of the mounting plate, and the arrangement of the mounting groove on the mounting plate and the mounting buckle on the cover plate facilitates the assembly by the staff and improves the assembly efficiency.
