Referring to fig. 1a to 6, the handle linkage structure includes: fixing base 2, first connecting portion 3, second connecting portion 4 and guide pin 5. In the following, in order to describe the connection relationship between the respective members, "inner end" and "outer end" are introduced, wherein "inner end" refers to an end of the handle linkage structure near the square core, and "outer end" refers to an end of the handle linkage structure near the handle.
The outer end of the fixing seat 2 is a cylindrical or cylindrical limiting part 21 for limiting the first connecting part 3, the second connecting part 4 and the guide pin 5. In this embodiment, a cylindrical stopper is adopted, and the first connecting portion 3, the second connecting portion 4, and the guide pin 5 are disposed inside thereof, respectively; the inner end of the fixing seat 2 is a cylindrical mounting part 22, and the diameter of the mounting part 22 is larger than that of the limiting part 21, so that the handle linkage structure can be fixedly mounted on the door lock. Specifically, two axially sliding grooves 23 are symmetrically provided on the inner wall of the stopper 21, and both ends of the guide pin 5 are provided in the sliding grooves 23 so as to be axially slidable.
The first connecting part 3 is rotatably arranged on the fixed seat 2 around the axial direction, the inner end of the first connecting part is provided with a square core hole 31, and the outer end of the first connecting part is cylindrical and provided with two first connecting grooves 32. One end of the square core hole 31 of the first connecting part 3 is arranged outside the fixed seat 2 and can be connected with the square core when in use; one end of the first connecting groove 32 of the first connecting portion 3 is provided in the limiting portion 21 for cooperation with the second connecting portion 4 and the guide pin 5. The middle part at first connecting portion 3 is equipped with annular cardboard 33, is equipped with annular recess on the interior terminal surface of spacing portion 21, and cardboard 33 is established in this recess, can prevent the removal of first connecting portion 3 to the distal end, can also realize that first connecting portion 3 and fixing base 2 rotate to be connected.
The groove wall on one side of the first connecting groove 32 is an inclined surface, and since the outer end of the first connecting part 3 is cylindrical in this embodiment, the groove wall on the side of the first connecting groove 32 is a spiral inclined surface which is arranged on the cylinder wall and is wound in the axial direction; the other side groove wall of the first connecting groove 32 is a plane parallel to the axial direction. The two first connecting grooves 32 are symmetrically arranged along the circumferential angle of the first connecting portion 3, so that the side wall of the guide pin 5 radially penetrating therein can simultaneously abut on the two spiral inclined surfaces. The width of the end of the first connecting groove 32 near the Fang Xinkong is smaller than the width of the end far away from Fang Xinkong.
The inner end of the second connecting part 4 is of a cylindrical structure and sleeved at the outer end of the first connecting part 3, and the second connecting part and the first connecting part can rotate relatively. In addition, when the outer end of the first connecting portion 3 is cylindrical, the inner end of the second connecting portion 4 may be inserted into the outer end of the first connecting portion 3, and the two can be rotated relative to each other.
The outer end of the second connecting portion 4 is used for being connected with the handle 1, as shown in fig. 2a and 2b, a pit is arranged on the side wall of the outer end of the second connecting portion 4, a screw 11 passes through the handle 1 to be abutted in the pit, the handle 1 is fixedly connected with the second connecting portion 4, and the second connecting portion can move simultaneously with the handle 1, for example, pushing the handle 1 to the inner end, pulling the handle 1 to the outer end, and rotating the handle 1 clockwise or anticlockwise can make the second connecting portion 4 move in the same manner.
The guide pin 5 is a cylinder penetrating the first connecting portion 3 in the radial direction and located in the two first connecting grooves 32, both ends of which are provided in the sliding groove 23, and the side faces of which abut on the spiral inclined surfaces of the two first connecting grooves 32 and the inner ends of the second connecting portions 4.
When the lock is used, the second connecting part 4 is pushed to the inner end, so that the guide pin 5 moves to the inner end along the sliding groove 23, and the side surface of the guide pin 5 is abutted on the spiral inclined surface of the first connecting groove 32, and the guide pin 5 can not rotate around the axial direction, so that the first connecting part 3 can rotate under the pushing of the guide pin 5, and meanwhile, the inner end of the first connecting part 3 can drive the square core of the lock to rotate together. Through adjusting the inclination direction and the inclination angle of the spiral inclined plane, the rotation direction and the rotation angle of the first connecting part 3 can be adjusted, the square core can be conveniently controlled to rotate in a preset direction and angle, and the function of retracting the lock tongue is realized.
In the initial state, namely before unlocking, the guide pin 5 is arranged at the far end of the first connecting groove 32, so after the handle linkage structure is arranged at two sides of the door lock, when the handle 1 at one side of the door lock is pushed to the inner end, the handle linkage structure at the side moves and drives the square core to rotate, the first connecting part 3 at the other side rotates simultaneously, but because the width of the far end of the first connecting groove 32 is larger than the diameter of the guide pin 5, the guide pin 5 cannot move axially in the first connecting groove 32, and the second connecting part 4 at the other side and the handle 1 are not driven to move simultaneously, so that the force required for unlocking can be reduced, and the unlocking of a user is facilitated.
The groove wall on one side of the first connecting groove 32 is an inclined plane, and the groove wall on the other side is a plane parallel to the axial direction, so that unlocking can be realized, and meanwhile, the force required for unlocking can be reduced. In another embodiment, the groove walls on both sides of the first connecting groove 32 may be two inclined surfaces, but it is required to ensure that the width of the end of the first connecting groove 32 near the Fang Xinkong is not greater than the width of the end far from Fang Xinkong, i.e. the width of the notch is not less than the width of the groove bottom. At this time, when unblanking, promote second connecting portion 4 can drive first connecting portion 3 and rotate, when first connecting portion 3 of lock opposite side rotates, guide pin 5 is motionless or to the one side that is close to the square core remove, can not drive second connecting portion 4 and handle 1 simultaneous movement of this side, consequently compare in traditional lock, can reduce the dynamics that unblanks required equally.
In another embodiment, the distal end of the first connecting portion 3 may be cylindrical, and the proximal end of the second connecting portion 4 may be cylindrical and fit around the outer periphery of the first connecting portion 3, so that the two can be rotated relatively.
In addition, in still another embodiment, the number of the slide grooves 23 and the first connecting grooves 32 may be set to one, while the distal end of the first connecting portion 3 is set to a cylindrical shape, and accordingly, the first connecting grooves 32 have only one side end opening and one tip end opening. At this time, one end of the guide pin 5 is provided in the slide groove 23, and the other end thereof abuts against a side end wall of the first connecting groove 32 near the axial center, and the side wall of the guide pin 5 also abuts against the inclined groove wall of the first connecting groove 32. With this structure, the guide pin 5 can also drive the first connecting portion 3 to rotate when the second connecting portion 4 is pushed inward.
In addition, in another embodiment, the limiting portion 21 may be cylindrical, the first connecting portion 3 and the second connecting portion 4 are correspondingly sleeved on the outer periphery, and the guide pin 5 is inserted therein, so that the functions of limiting and unlocking can be achieved.
In the above embodiment unlocking is achieved by pushing the first connecting part 3 towards the inner end, in a further embodiment unlocking may also be achieved by rotating the first connecting part 3 clockwise or counter-clockwise. Specifically, two V-shaped second connecting grooves 41 are symmetrically provided in the circumferential direction at the inner end of the second connecting portion 4, the tip opening of the second connecting groove 41 is provided opposite to the tip opening of the first connecting groove 32, and the groove wall of the first connecting groove 32 abuts against the side surface of the guide pin 5. In the initial state, the guide pin 5 is positioned at the bottom of the second connecting groove 41, and when the second connecting part 4 is rotated clockwise or anticlockwise, the inclined groove wall of the second connecting groove 41 can push the guide pin 5 to move to the inner end and unlock the lock because the rotation of the guide pin 5 around the axial direction is limited; when the second connecting portion 4 is pushed to the inner end, the bottom end of the second connecting groove 41 can directly push the guide pin 5 to move to the inner end and realize unlocking. Needless to say, when the number of the slide grooves 23 and the first coupling grooves 32 is also set to one, the second coupling groove 41 may be set to one as well, and at this time, the first coupling portion 3 may be rotated clockwise or counterclockwise to unlock.
In addition, in this embodiment, two T-shaped limiting grooves 24 are symmetrically disposed on the inner wall of the limiting portion 21, the head of the T-shaped limiting groove 24 is disposed along the circumferential direction, the tail of the T-shaped limiting groove 24 is parallel to the axial direction, and the T-shaped limiting groove 24 is a groove body recessed toward the inner wall of the limiting portion 21. Meanwhile, two groups of first bosses 42 and second bosses 43 are symmetrically arranged on the side face of the second connecting portion 4, the first bosses 42 and the second bosses 43 in the same group are located on the same straight line, and the height of the first bosses 42 is smaller than that of the second bosses 43. The distance between the outer side surfaces of the two first bosses 42 is smaller than the inner diameter of the limiting part 21, and the distance between the outer side surfaces of the two second bosses 43 is smaller than the distance between the bottoms of the two T-shaped limiting grooves 24. Wherein, the first boss 42 is arranged opposite to the tail of the T-shaped limit groove 24; the second boss 43 is disposed opposite to the head of the T-shaped limiting groove 24. In addition, a limiting clamping table 25 facing between the first boss 42 and the second boss 43 is further arranged on the inner wall of the limiting portion 21 along the circumferential direction, the limiting clamping table 25 is arc-shaped, the width of the limiting clamping table 25 is slightly smaller than the distance between the second boss 43 and the first boss 42, and the inner diameter of the limiting clamping table 25 is smaller than the distance between the outer side surfaces of the two first bosses 42.
In the initial state, the second boss 43 is positioned at the head of the T-shaped limit groove 24 and the inner end faces the tail of the T-shaped limit groove 24, at the moment, the second connecting part 4 is pushed to the inner end, the second boss 43 can enter the tail of the T-shaped limit groove 24, and then the second connecting part 4 can rotate around the axial direction and is limited by the tail of the T-shaped limit groove 24; in the initial state, the second connecting portion 4 is rotated clockwise or anticlockwise, the limiting clamping table 25 is located in a gap between the first boss 42 and the second boss 43, and the second connecting portion 4 is limited by the limiting clamping table 25 in the axial movement. In other words, when the door lock adopting the handle linkage structure pushes the handle to unlock, the handle can not rotate any more; when the handle is rotated clockwise or anticlockwise to unlock, the handle can not move inwards any more, so that the unlocking process is ensured to be more stable.
In addition, a return spring 6 may be sleeved on the first connecting portion 3, the outer end of the return spring 6 abuts against the side surface of the guide pin 5, and the inner end of the return spring 6 is fixedly arranged, for example, may abut against the first connecting portion 3 or the limiting portion 21. When the second connecting part 4 is rotated or pushed to the inner end to unlock, the guide pin 5 moves to the inner end, the reset spring 6 is compressed at the same time of unlocking, and after unlocking is completed and the second connecting part 4 loses the external force, the reset spring 6 rebounds to enable the guide pin 5 to push the second connecting part 4 to restore to the initial position.
In addition, in this embodiment, a sealing plate 7 is further disposed at one side of the inner end of the fixing base 2, and a circular mounting hole is disposed in the middle of the sealing plate 7 for restricting the movement of the first connecting portion 3 toward the inner end; two ends of the sealing plate 7 are connected to the inner end side wall of the fixed seat 2 through bolts. Specifically, the first connecting portion 3 has a square core connecting portion 34 penetrating the circular mounting hole at an inner end side thereof, the square core connecting portion 34 is cylindrical, and the Fang Xinkong is provided at an inner end side thereof. A torsion spring connecting part 35 is further arranged at one side of the inner end of the first connecting part 3, and the torsion spring connecting part 35 is positioned between the square core connecting part 34 and the clamping plate 33. The external dimension of the torsion spring connecting part 35 is larger than the diameter of the square core connecting part 34, so that the reset torsion spring 8 is convenient to set.
A limiting groove or a limiting hole is arranged on the torsion spring connecting part 35 and is used for fixing one torsion arm of the reset torsion spring 8; meanwhile, a limit groove or a limit hole is also arranged on one side of the inner end of the fixed seat 2 and used for fixing the other torsion arm of the reset torsion spring 8. Referring to fig. 1b, fig. 2b and fig. 3a, one torsion arm of the reset torsion spring 8 is inserted into a limit groove on the torsion spring connecting portion 35, and the other torsion arm of the reset torsion spring 8 is inserted into a limit groove on the fixing base 2. When the first connecting portion 3 rotates clockwise or counterclockwise, the reset torsion spring 8 is pressed and drives the first connecting portion 3 to rotate counterclockwise or clockwise. In other words, after the first connecting portion 3 rotates to unlock, the reset torsion spring 8 can drive the first connecting portion 3 to restore to the initial state, so as to facilitate subsequent unlocking. Of course, in other embodiments, the reset torsion spring 8 may be omitted, and a mechanism in the lock that can reset the square core 9 may be used to indirectly restore the first connecting portion 3 to the initial state.
In addition, when the groove walls of the two sides of the first connecting groove 32 are parallel inclined planes, the return spring 6 can drive the first connecting portion 3 to restore to the original state when pushing the guide pin 5 to move to the outer end. Therefore, when the groove walls on both sides of the first connecting groove 32 are parallel inclined surfaces, only one return spring 6 and only one return torsion spring 8 may be provided, or only a mechanism capable of resetting the square core 9 in the lock is selected, so that the first connecting portion 3 and the second connecting portion 4 are indirectly restored to the initial state.

Referring to fig. 7 and 8, the door lock includes a lock assembly 10, two handle linkage structures and two handles 1. The lock assembly 10 is internally provided with square cores 9 extending to two sides of the door, the square cores 9 are linked with the lock tongue through a series of mechanisms, and the lock tongue can be retracted by rotating the square cores 9, so that unlocking is realized. The connection mode between the square core 9 and the lock tongue is not an innovation point of the present disclosure, and various connection modes exist in the prior art, so that a description thereof is omitted.
The two handle linkage structures are symmetrically arranged on two sides of the lock assembly 10, the inner end of the first connecting part 3 is connected with the outer end of the square core 9, and the outer end of the second connecting part 4 is connected with the inner end of the handle 1. When the handle 1 at one side of the door lock is rotated or pushed to the inner end, the square core 9 can be driven to rotate to unlock, and meanwhile, the handle 1 at the other side of the door lock cannot move at the same time, so that unlocking can be realized by applying smaller acting force to the handle 1.
