Abstract
Disclosed is a door lock rotation direction switching mechanism. The door lock rotation direction switching mechanism comprises a door lock body, a hand-held head, a position-changing shifting wheel and a disengagement pin. The hand-held head is fixedly mounted on the door lock body; one end of the hand-held head is provided with a mounting opening; an annular step is disposed in the mounting opening; a shaft shoulder matched with the annular step is disposed on one side of the position-changing shifting wheel; a protruding block which is integrated with the position-changing shifting wheel is disposed on the outer wall of the position-changing shifting wheel; a protruding block receding groove is formed in one side in the mounting opening; a disengagement pin hole is formed in the side wall of the middle of the protruding block receding groove; the disengagement pin is inserted into the disengagement pin hole; when the head end of the disengagement pin is located in the protruding block receding groove, the protruding block is located on the left side or the right side of the disengagement pin; the position-changing shifting wheel and the mounting opening are relatively fixed; when the head end of the disengagement pin leaves the protruding block receding groove; the position-changing shifting wheel can rotate relative to the mounting opening; the protruding block slides in the protruding block receding groove. The door lock rotation direction switching mechanism is simple in structure and convenient and flexible to use; direction switching and adjusting can be completed without operating internal parts by dismantling a sealing cover and without tools.
Description
Technical field
The present invention relates to door lock manufacturing technology field, be specifically related to door lock rotation direction conversion (clutch) mechanism.
Background technology
Door lock rotation direction of the present invention switching mechanism is mainly used on Household door lock, for adapting to the design (L.H.flapped door in enabling direction, R.H.flapped door), common door handle is the enabling direction being installed as dextrorotation, in actual applications, door handle need be installed as to left-handed enabling direction according to the installation environment of door or the requirement of householder, when transformation door handle rotation direction realizes L.H.flapped door or R.H.flapped door, need adjust internal construction, traditional door lock rotation direction switching mechanism complex structure, thumb wheel direction could be changed after capping need being disassembled during adjustment, regulate loaded down with trivial details inconvenience.
Summary of the invention
For the deficiencies in the prior art, the invention provides the switching mechanism of a kind of door lock rotation direction.
To achieve these goals, the technical solution adopted for the present invention to solve the technical problems is: the switching mechanism of door lock rotation direction, comprise door lock body, handle head, transposition thumb wheel, on-of pin, connect square bar, capping, described handle head is fixedly installed on door lock body, one end of handle head is provided with installing port, ring-shaped step is provided with in installing port, the side of transposition thumb wheel is provided with the shaft shoulder matched with ring-shaped step, be positioned at transposition thumb wheel outer wall on be provided with and the thumb wheel all-in-one-piece projection that replaces, the side being positioned at installing port offers projection slot to make way, clutch pin-and-hole is offered in sidewall in the middle part of projection slot to make way, clutch pin-and-hole interpolation is connected to on-of pin, when the head end of on-of pin is positioned at projection slot to make way, projection is positioned at left side or the right side of on-of pin, and transposition thumb wheel is relative with installing port fixing, when the head end of on-of pin leaves in projection slot to make way, transposition thumb wheel can be mounted opposite mouth and rotate, projection slides in projection slot to make way.
The door lock rotation direction switching mechanism that the present invention further provides, be positioned at its construction opening and the sidewall of the opposite side of projection slot to make way is provided with detent mechanism, described detent mechanism is made up of retainer spring and positioning ball, retainer spring encapsulation is in being arranged in the blind hole on construction opening inside wall, the top, one end of retainer spring is pressed in blind via bottom, other end top is pressed on positioning ball, and positioning ball top is pressed on transposition thumb wheel, and described transposition thumb wheel offers location dimples.
The door lock rotation direction switching mechanism that the present invention further provides, it connects the middle part that square bar is fixedly interspersed in transposition thumb wheel, and described capping is fixedly connected on construction opening, and conversion peraccidens thumb wheel slides axially.
Beneficial effect of the present invention: structure of the present invention is simple, easy-to-use, flexible, when realizing conversion, does not need dismounting capping manipulation inner body, does not substantially need instrument just can complete direction conversion adjustment.
Accompanying drawing explanation
Fig. 1 is the first structural representation of the present invention;
Fig. 2 is the second structural representation of the present invention.
Detailed description of the invention
Door lock rotation direction switching mechanism as depicted in figs. 1 and 2, comprise door lock body, handle head 1, transposition thumb wheel 2, on-of pin 3, connect square bar 4, capping 5, described handle head 1 is fixedly installed on door lock body, one end of handle head 1 is provided with installing port, ring-shaped step is provided with in installing port, the side of transposition thumb wheel 2 is provided with the shaft shoulder matched with ring-shaped step, be positioned at transposition thumb wheel 2 outer wall on be provided with and the thumb wheel 2 all-in-one-piece projection 6 that replaces, the side being positioned at installing port offers projection slot to make way 7, clutch pin-and-hole is offered in sidewall in the middle part of projection slot to make way 7, clutch pin-and-hole interpolation is connected to on-of pin 3, when the head end of on-of pin 3 is positioned at projection slot to make way 7, projection 6 is positioned at left side or the right side of on-of pin 3, and transposition thumb wheel 2 is relative with installing port fixing, when the head end of on-of pin 3 leaves in projection slot to make way 7, transposition thumb wheel 2 can be mounted opposite mouth and rotate, projection 6 slides in projection slot to make way 7.
Be positioned at construction opening and the sidewall of the opposite side of projection slot to make way 7 is provided with detent mechanism, described detent mechanism is made up of retainer spring 8 and positioning ball 9, retainer spring 8 encapsulation is in being arranged in the blind hole on construction opening inside wall, the top, one end of retainer spring 8 is pressed in blind via bottom, other end top is pressed on positioning ball 9, positioning ball 9 top is pressed on transposition thumb wheel 2, and described transposition thumb wheel 2 offers location dimples.
Described connection square bar 4 is fixedly interspersed in the middle part of transposition thumb wheel 2, and described capping 5 is fixedly connected on construction opening and conversion peraccidens thumb wheel 2 slides axially.
This clutch is mainly used on Household door lock, is (L.H.flapped door, the R.H.flapped door) of the design of applicable enabling direction; Common door handle is that R.H.flapped door direction is arranged, but when encountering L.H.flapped door, this mechanism only needs to forward transposition thumb wheel to a direction, and just can complete direction conversion, old structure just can change thumb wheel direction after just must disassembling capping. applicability is loaded down with trivial details.So this mechanism is easy-to-use, flexibly, instrument is not substantially needed just can to complete direction conversion.
Although this manual is described according to embodiment, but not each embodiment only comprises an independently technical scheme, this narrating mode of manual is only for clarity sake, those skilled in the art should by manual integrally, technical scheme in each embodiment also through appropriately combined, can form other embodiments that it will be appreciated by those skilled in the art that.
