Description

[Technical Field]

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS This application claims priority to and benefit of a Chinese patent application bearing application number 2021116760283, filed on December 31, 2021, and entitled "Handle interlocking structure and handle assembly," the entire contents of which are incorporated herein by reference.

[0002] The present disclosure relates to the technical field of locks, and more particularly to a handle interlocking structure and a handle assembly. [Background technology]

[0003] A door lock handle is typically connected directly to the lock's internal core. Rotating the handle rotates the core, retracting the lock's tang and unlocking the lock. However, different users have different unlocking habits, such as rotating the handle clockwise, counterclockwise, pushing the handle inward, or pulling the handle outward. Conventional door lock handles generally support only one of these unlocking methods, which can lead to poor user experience with door locks used in public places. Furthermore, handles are installed on both the inside and outside of the door. When one handle is rotated / pushed / pulled, the other handle simultaneously operates, requiring a large external force to unlock the door lock. Summary of the Invention

[0004] SUMMARY OF THE INVENTION An object of the present disclosure is to provide a handle interlocking structure and a handle assembly having the handle interlocking structure to solve at least one of the above technical problems.

[0005] In order to achieve the above object, the handle interlocking structure according to the present disclosure comprises: a fixed base having a cylindrical first position limiting portion at one end thereof; The fixed base has a shaft Weeka first connecting part that is rotatably installed on the fixed base, has a square core hole at one end, and the other end is inserted into the fixed base, and has a first connecting groove on the outer periphery, one side of which has a groove wall that is an inclined surface, and the width of the end of the first connecting groove that is close to the square core hole is smaller than the width of the end that is away from the square core hole; a second connecting portion having a cylindrical structure at one end and fitted to the other end of the first connecting portion; The guide pin is slidably installed within the first position limiting portion along the axial direction, and has a side surface that abuts against the end of the second connecting portion that is close to the fixed base and the inclined surface.

[0006] In order to achieve the above object, the handle assembly according to the present disclosure comprises: The handle interlocking structure; a handle, one end of which is fitted to the other end of the fixed base, which is swingable radially around the first connecting portion, and which abuts against the end surface of the second connecting portion.

[0007] As can be seen from the above description and practice, in the handle interlocking structure described in the present disclosure, the second connecting part can push the guide pin to move to the inner end, and the guide pin can only slide along the axial direction in the fixed base, and the shaft Week Since the handle cannot rotate independently, the first connecting part is pushed and rotated by the guide pin, and therefore the inner end of the first connecting part rotates the lock core simultaneously in conjunction with the handle, thereby realizing unlocking. By applying this handle interlocking structure to a handle assembly, fitting the handle to the other end of the fixed base and setting it so that it can swing only radially around the first connecting part, the handle and the lock core can be indirectly connected, and when the handle on one side of the door lock is pushed or pulled, the second connecting part moves to the inner end to unlock the door, and the handle on the other side of the door lock does not move at the same time, reducing the force required to unlock the door. [Brief explanation of the drawings]

[0013] Example 1 This embodiment discloses a handle linkage structure that is installed between a handle and a square core of a door lock during use to connect them. Figures 1a and 1b show two cross-sectional views of the handle linkage structure, the two cross-sectional views being arranged along the center of the handle linkage structure and perpendicular to each other. Figures 2a and 2b show the exploded structure of the handle linkage structure at two different viewing angles. Figures 3a and 3b show the structure of the fixed base of the handle linkage structure at two different viewing angles. Figures 4a and 4b show the structure of the first connecting part of the handle linkage structure at two different viewing angles. Figures 5a and 5b show the structure of the second connecting part of the handle linkage structure at two different viewing angles. Figure 6 shows the structure of the return torsion spring of the handle linkage structure.

[0014] 1a to 6, the handle interlocking structure includes a fixed base 2, a first connecting part 3, a second connecting part 4, and a guide pin 5. In the following, to explain the connection relationship between each part, the terms "inner end" and "outer end" are introduced, where the "inner end" refers to the end of the handle interlocking structure that is close to the square core, and the "outer end" refers to the end of the handle interlocking structure that is close to the handle.

[0015] The outer end of the fixed base 2 is provided with cylindrical first and second position limiting portions 21 and 25 for limiting the positions of the first and second connecting portions 3, 4, and guide pin 5. The diameter of the first position limiting portion 21 is larger than that of the second position limiting portion 25, and the first position limiting portion 21 is located on the outer periphery of the second position limiting portion 25. The inner end of the fixed base 2 is a cylindrical mounting portion 22, the diameter of which is larger than that of the first position limiting portion 21, allowing the handle interlocking mechanism to be fixedly attached to a door lock. The inner ends of the first and second position limiting portions 21 and 25 are fixedly connected to the mounting portion 22, and in this embodiment, the three are integrally formed, making manufacturing easier. Two second sliding grooves 26 are symmetrically formed on the inner wall of the second position limiting portion 25 along the axial direction, and the guide pin 5 is inserted into the second sliding grooves 26 and can slide along the axial direction.

[0016] The first connecting portion 3 is axially inserted into the second position limiting portion 25. Week The first connecting part 3 is rotatably mounted on the fixed base 2, with a square core hole 31 formed on its inner end and a cylindrical outer end with two first connecting grooves 32. The end of the first connecting part 3 with the square core hole 31 is mounted on the outside of the fixed base 2 and can be connected to the square core during use, while the end of the first connecting part 3 with the first connecting groove 32 is mounted within the second position limiting part 25 and engages with the second connecting part 4 and the guide pin 5. An annular locking base 33 is mounted at the middle of the first connecting part 3, abutting against the end face of the second position limiting part 25, and can prevent the first connecting part 3 from moving toward the distal end.

[0017] The groove wall on one side of the first connecting groove 32 is an inclined surface. In this embodiment, since the outer end of the first connecting part 3 is cylindrical, the groove wall on that side of the first connecting groove 32 is inclined to the axis installed on the cylindrical wall. Week The groove wall on the other side of the first connecting groove 32 is a flat surface parallel to the axial direction. The two first connecting grooves 32 are arranged along the circumferential direction of the first connecting portion 3. PointBecause they are installed symmetrically, the side walls of the guide pin 5 inserted along the radial direction can abut against the two spiral inclined surfaces simultaneously. The width of the end of the first connecting groove 32 close to the square core hole 31 is smaller than the width of the end away from the square core hole 31.

[0018] The inner end of the second connecting part 4 has a cylindrical structure and is fitted into the outer end of the second position limiting part 25, thereby allowing the second connecting part 4 and the first connecting part 3 to rotate relative to each other. The outer end of the second connecting part 4 is used to connect with the handle 1, and for example, the handle 1 and the second connecting part 4 can be fixedly connected. In this case, the second connecting part 4 can move simultaneously with the handle 1, and for example, whether the handle 1 is pushed toward the inner end, pulled toward the outer end, or rotated clockwise or counterclockwise, the second connecting part 4 can move in the same manner as the handle 1.

[0019] The guide pin 5 is a cylindrical body that passes radially through the first connecting portion 3 and the second position limiting portion 25 and is located within the two first connecting grooves 32 and the two second sliding grooves 26, with its side surfaces abutting the spiral inclined surfaces of the two first connecting grooves 32 and the inner end of the second connecting portion 4.

[0020] In use, by pushing the second connecting portion 4 toward the inner end, the guide pin 5 is moved toward the inner end along the second sliding groove 26, and the side surface of the guide pin 5 abuts against the spiral inclined surface of the first connecting groove 32, and the guide pin 5 is aligned with the axis. Week Since the first connecting part 3 cannot rotate independently, the first connecting part 3 is pushed by the guide pin 5 to rotate, and at the same time, the inner end of the first connecting part 3 can rotate the square core of the lock simultaneously in conjunction with the first connecting part 3. By adjusting the inclination direction and inclination angle of the spiral inclined surface, the rotation direction and rotation angle of the first connecting part 3 can be adjusted, and the square core

[0021] In the initial state, i.e., before unlocking, the guide pin 5 is installed at the distal end of the first connecting groove 32. After the handle interlocking structures are installed on both sides of the door lock, when the handle 1 on one side of the door lock is pressed toward the inner end, the handle interlocking structure on that side moves to rotate the square core in an interlocking manner, and the first connecting part 3 on the other side rotates at the same time. However, since the width of the distal end of the first connecting groove 32 is larger than the diameter of the guide pin 5, the guide pin 5 does not move axially within the first connecting groove 32, and does not cause the second connecting part 4 and the handle 1 on the other side to move in an interlocking manner at the same time. This reduces the force required for unlocking and makes it easier for the user to unlock the door.

[0022] One side of the first connecting groove 32 has an inclined wall, while the other side has a flat surface parallel to the axial direction, which allows for unlocking and reduces the force required for unlocking. In another embodiment, the groove walls on both sides of the first connecting groove 32 may be configured as two inclined surfaces, but the width of the end of the first connecting groove 32 closest to the square core hole 31 must be equal to or less than the width of the end away from the square core hole 31, i.e., the width of the groove opening must be equal to or greater than the width of the groove bottom. In this case, when unlocking, the first connecting part 3 can be rotated by pressing the second connecting part 4. When the first connecting part 3 on the other side of the door lock rotates, the guide pin 5 remains stationary or moves toward the side closer to the square core, preventing the second connecting part 4 and handle 1 on that side from moving simultaneously. This also reduces the force required for unlocking compared to conventional door locks.

[0023] In another embodiment, the distal end of the first connecting portion 3 may be cylindrical, and accordingly the proximal end of the second connecting portion 4 may be cylindrical and fitted onto the outer periphery of the first connecting portion 3 or the second position limiting portion 25, in which case relative rotation between the first connecting portion 3 and the second connecting portion 4 can be similarly achieved.

[0024] In yet another embodiment, the number of second sliding grooves 26 and first connecting grooves 32 may be one, and the distal end of the first connecting portion 3 may be cylindrical, so that the first connecting groove 32 has only one side end opening and one tip end opening. In this case, one end of the guide pin 5 is installed in the second sliding groove 26, and the other end abuts against the side end wall close to the axis of the first connecting groove 32, and the side wall of the guide pin 5 similarly abuts against the inclined groove wall of the first connecting groove 32. In this structure, when the second connecting portion 4 is pushed inward, the guide pin 5 can similarly rotate the first connecting portion 3 in conjunction with the guide pin 5.

[0025] In the above embodiment, the lock is unlocked by pushing the second connecting part 4 toward the inner end, and in another embodiment, the lock can also be unlocked by rotating the second connecting part 4 clockwise or counterclockwise. Specifically, two V-shaped second connecting grooves 41 are symmetrically arranged along the circumferential direction at the inner end of the second connecting part 4, and the groove openings of the second connecting grooves 41 face the first connecting part 3, while the groove walls of the first connecting groove 32 abut against the side surfaces of the guide pin 5. In the initial state, the guide pin 5 is located at the bottom of the second connecting groove 41, and when the second connecting part 4 is rotated clockwise or counterclockwise, the axis of the guide pin 5 moves in the opposite direction. Week Since rotation of the second connecting groove 41 is restricted, the inclined groove wall of the second connecting groove 41 can push the guide pin 5 to move it to the inner end to unlock, and when the second connecting part 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 it to the inner end to unlock. Of course, when the number of the second sliding groove 26 and the first connecting groove 32 is one, the number of the second connecting groove 41 may also be one, and in this case, the first connecting part 3 can be rotated clockwise or counterclockwise to unlock in the same way.

[0026] In addition, in this embodiment, two first sliding grooves 23 are further installed symmetrically on the inner wall of the first position limiting portion 21, and the first sliding groove 23 and the second sliding groove 26 are installed opposite each other to accommodate the end of the guide pin 5, thereby making the movement of the guide pin 5 within the fixed base 2 more stable.

[0027] In this embodiment, two T-shaped first position limiting grooves 24 are further symmetrically arranged on the inner wall of the first position limiting portion 21, and the first position limiting grooves 24 have heads arranged along the circumferential direction and tails parallel to the axial direction, and are grooves recessed toward the inner wall of the first position limiting portion 21. At the same time, two position limiting bosses 42 are symmetrically arranged on the side surface of the second connecting portion 4. In the initial state, the position limiting bosses 42 are located at the heads of the first position limiting grooves 24, with the inner ends facing the tails of the first position limiting grooves 24. At this time, when the second connecting portion 4 is pressed toward the inner ends, the position limiting bosses 42 enter the tails of the first position limiting grooves 24, and then move toward the axial direction of the second connecting portion 4. Week The rotation of the second connecting part 4 toward the inner end is limited by the tail of the first position limiting groove 24, and in the initial state, when the second connecting part 4 is rotated clockwise or counterclockwise, the movement of the second connecting part 4 toward the inner end is limited by the head of the first position limiting groove 24. In other words, by using a door lock with this handle interlocking structure, the handle cannot rotate when it is pushed toward the inner end to unlock, and the handle cannot move inward when it is rotated clockwise or counterclockwise to unlock, which ensures a more stable unlocking process.

[0028] A return spring 6 may also be fitted to the second position limiting part 25, with the outer end of the return spring 6 abutting against the side surface of the guide pin 5 and the inner end being fixedly installed, for example, abutting against the inner end surface of the second position limiting part 25. When the second connecting part 4 is rotated or pushed toward the inner end to unlock, the guide pin 5 moves toward the inner end, compressing the return spring 6 while unlocking, completing unlocking, and after the second connecting part 4 loses its external force, the guide pin 5 pushes the second connecting part 4 back to its initial position due to the rebound of the return spring 6.

[0029] In this embodiment, a first sealing plate 71 is further installed on the inner end side of the fixed base 2, and a circular mounting hole is formed in the middle of the first sealing plate 71 to restrict movement of the first connecting part 3 toward the inner end. An annular locking base 27 is installed within the mounting part 22, and locking grooves are formed in the locking base 27 to accommodate the two ends of the first sealing plate 71. An annular locking groove 29 is further formed on the inner wall of the locking base 27, and an elastic hole-mounted retaining ring 28 is installed in the annular locking groove 29. One side of the first sealing plate 71 abuts against the annular locking base 33, and the other side abuts against the elastic hole-mounted retaining ring 28, thereby restricting movement of the first connecting part 3 toward the inner end. A square core connecting part 34 is installed on the inner end side of the first connecting part 3 and is inserted into the circular mounting hole. The square core connecting part 34 is cylindrical, and the square core hole 31 is formed on its inner end.

[0030] The return torsion spring 8 is further fitted into the annular locking base 33, and a position limiting groove or a position limiting hole is provided on the annular locking base 33 for fixing one torsion arm of the return torsion spring 8, and the first seal plate 71 also has a position limiting groove or a position limiting hole for fixing the other torsion arm of the return torsion spring 8. Referring to FIGS. 1a, 2b, and 4a, one torsion arm of the return torsion spring 8 is inserted into the position limiting groove of the annular locking base 33, and the other torsion arm of the return torsion spring 8 is inserted into the position limiting groove of the first seal plate 71. When the first connecting part 3 rotates clockwise or counterclockwise, the return torsion spring 8 is subjected to pressure and drives the first connecting part 3 to rotate counterclockwise or clockwise. In other words, after the first connection part 3 has rotated to complete unlocking, the return torsion spring 8 can drive the first connection part 3 to return it to its initial state, facilitating subsequent unlocking. The other torsion arm of the return torsion spring 8 may also be fixed to the inner wall of the fixed base 2, which can similarly achieve the above-mentioned return effect. Of course, in other embodiments, the return torsion spring 8 may be omitted, and a mechanism that can return the square core within the lock may be used to indirectly return the first connection part 3 to its initial state.

[0031] Furthermore, when the groove walls on both sides of the first connecting groove 32 are parallel inclined surfaces, the return spring 6 can also return the first connecting part 3 to its initial state in conjunction with the guide pin 5 when it is pushed to move it to the outer end. Therefore, when the groove walls on both sides of the first connecting groove 32 are parallel inclined surfaces, only one of the return spring 6 and the return torsion spring 8 may be installed to indirectly return the first connecting part 3 and the second connecting part 4 to their initial states, or only a mechanism that can return the square core in the lock may be used.

[0032] In this embodiment, a handle assembly using the above-mentioned handle interlocking structure is further disclosed, in which Figures 7a and 7b show the structure of two cross sections of the handle assembly, the two cross sections being installed along the center of the handle assembly and perpendicular to each other, Figure 8 shows the exploded structure of the handle assembly, in which the first connecting part 3, guide pin 5, return spring 6, first seal plate 71, return torsion spring 8 and hole elastic retaining ring 28 are hidden in order to show many details, and Figure 9 shows the structure of the handle in the handle assembly. 7a to 9, the handle assembly includes the handle interlocking structure and the handle 1, and one end of the handle 1 (the lower end in Fig. 7a) is fitted into the outer end side of the second position limiting part 25 and abuts against the outer end surface of the second connecting part 4, and can swing around the radial direction of the second position limiting part 25. Either by pushing the other end of the handle 1 (the upper end in Fig. 7a) toward the inner end or by pulling the other end of the handle 1 (the upper end in Fig. 7a) toward the outer end, the second connecting part 4 can be slid toward the inner end, thereby realizing unlocking.

[0033] Specifically, a handle position limiting part 9 is provided at the lower end of the handle 1 and fitted to the outer end side of the second position limiting part 25, and the handle position limiting part 9 includes a stopper 91 and an elastic retaining ring 92 for the shaft. The middle part of the stopper 91 is rotatably mounted on the second position limiting part 25, and the outer periphery is mounted in an assembly hole 11 at the lower end of the handle 1. The outer shapes of the stopper 91 and the assembly hole 11 are rectangular, and the stopper 91 is positioned between the handle 1 and the shaft. WeekThe elastic retaining ring 92 for the shaft is installed on the side close to the outer end of the stopper 91 and limits the movement of the stopper 91 towards the outer end. On both the top and bottom sides of the assembly hole 11 at the lower end of the handle 1, protrusions 12 are installed extending between the outer end surface of the second connecting part 4 and the stopper 91, and the side surfaces of the protrusions 12 abut against the outer end surface of the second connecting part 4, so that when the upper end of the handle 1 is pushed or pulled, the handle 1 can swing around the radial direction of the second position limiting part 25, and at the same time, the protrusions 12 can move the second connecting part 4 towards the inner end to achieve unlocking. The stopper 91 also functions as a fulcrum when the handle 1 swings around the radial direction, and by limiting the movement of the handle 1 towards the outer end, the handle 1 can be secured to the shaft. Week It is possible to rotate only in the forward direction and oscillate only in the radial direction.

[0034] Alternatively, one end of the handle 1 may be fitted to the outer end side of the first position limiting part 21, abut against the outer end surface of the second connecting part 4, and swing around the radial direction of the first position limiting part 21. In such a structure, when the other end of the handle 1 is pushed or pulled, the second connecting part 4 is similarly moved to one side of the inner end, thereby realizing unlocking.

[0035] In this embodiment, the other end of the second connecting part 4 has a rectangular cross section and is installed in the assembly hole 11, so that when the handle 1 is rotated, the second connecting part 4 is also rotated in conjunction to achieve unlocking. Note that while the cross section of the other end of the second connecting part 4, the assembly hole 11, and the outer shape of the stopper 91 are all rectangular in this embodiment, they may be installed in other non-circular structures in other embodiments, and the above function can be similarly achieved.

[0036] <Example 2> In this embodiment, another handle assembly including another handle linkage structure is disclosed, which is not completely the same as the handle linkage structure in Example 1. Figures 10a and 10b show the exploded structure of the handle assembly at two different viewing angles, Figure 11 shows the three-dimensional structure of the handle assembly, and Figures 12a and 12b show the structure of the fixed base of the handle assembly at two different viewing angles.

[0037] 10a to 12b, the handle assembly is composed of a handle and a handle interlocking structure, and the handle can be interlocked with the square core of the lock via the handle interlocking structure. The handle interlocking structure includes a fixed base 2, a first connecting portion 3, a second connecting portion 4, and a guide pin 5. In the following, to explain the connection relationship between each component, the terms "inner end" and "outer end" are introduced, where the "inner end" refers to the end of the handle interlocking structure closest to the square core, and the "outer end" refers to the end of the handle interlocking structure closest to the handle.

[0038] The outer end of the fixed base 2 is provided with a cylindrical first position limiting portion 21 for limiting the positions of the first connecting portion 3, the second connecting portion 4, and the guide pin 5. The inner end of the fixed base 2 is a cylindrical mounting portion 22, the diameter of which is larger than that of the first position limiting portion 21, allowing the handle interlocking mechanism to be fixedly attached to a door lock. The inner end of the first position limiting portion 21 is fixedly connected to the mounting portion 22, and in this embodiment, the two are integrally formed, making manufacturing easy. Two first sliding grooves 23 are symmetrically formed along the axial direction on the inner wall of the first position limiting portion 21, and both ends of the guide pin 5 are installed in the first sliding grooves 23, allowing them to slide along the axial direction.

[0039] The first connecting portion 3 is axially connected to the fixed base 2. WeekThe first connecting part 3 is rotatably mounted on the fixed base 2, with a square core hole 31 at its inner end and a cylindrical outer end with two first connecting grooves 32. The end of the first connecting part 3 with the square core hole 31 is mounted on the outside of the fixed base 2 and can be connected to the square core during use, while the end of the first connecting part 3 with the first connecting groove 32 is mounted within the first position limiting part 21 and engages with the second connecting part 4 and the guide pin 5. An annular locking base 33 is mounted at the middle of the first connecting part 3, which abuts against the end face of the fixed base 2 and can prevent the first connecting part 3 from moving toward the distal end.

[0040] The groove wall on one side of the first connecting groove 32 is an inclined surface. In this embodiment, since the outer end of the first connecting part 3 is cylindrical, the groove wall on that side of the first connecting groove 32 is inclined to the axis installed on the cylindrical wall. Week The groove wall on the other side of the first connecting groove 32 is a flat surface parallel to the axial direction. The two first connecting grooves 32 are arranged along the circumferential direction of the first connecting portion 3. Point Because they are installed symmetrically, the side walls of the guide pin 5 inserted along the radial direction can abut against the two spiral inclined surfaces simultaneously. The width of the end of the first connecting groove 32 close to the square core hole 31 is smaller than the width of the end away from the square core hole 31.

[0041] The inner end of the second connecting part 4 has a cylindrical structure and is fitted into the outer end of the first connecting part 3, thereby allowing the second connecting part 4 and the first connecting part 3 to rotate relative to each other. The outer end of the second connecting part 4 is used to connect with the handle 1, and for example, the handle 1 and the second connecting part 4 can be fixedly connected. In this case, the second connecting part 4 can move simultaneously with the handle 1, and for example, whether the handle 1 is pushed toward the inner end, pulled toward the outer end, or rotated clockwise or counterclockwise, the second connecting part 4 can move in the same manner as the handle 1.

[0042] The guide pin 5 is a cylindrical body that penetrates the first connecting portion 3 radially and is located within the two first connecting grooves 32 and the two first sliding grooves 23, with its side surfaces abutting the spiral inclined surfaces of the two first connecting grooves 32 and the inner end of the second connecting portion 4.

[0043] In use, by pushing the second connecting portion 4 toward the inner end, the guide pin 5 is moved toward the inner end along the first sliding groove 23, and the surface of the guide pin 5 abuts against the spiral inclined surface of the first connecting groove 32, and the guide pin 5 is aligned with the axis. Week Since the first connecting part 3 cannot rotate independently, it is pushed by the guide pin 5 to rotate, and at the same time, the inner end of the first connecting part 3 can rotate the square core of the locking device in conjunction with it. By adjusting the inclination direction and inclination angle of the spiral inclined surface, the rotation direction and rotation angle of the first connecting part 3 can be adjusted, making it easy to control the predetermined rotation direction and angle of the square core and realizing the function of retracting the tongue.

[0044] In the initial state, i.e., before unlocking, the guide pin 5 is installed at the distal end of the first connecting groove 32. After the handle interlocking structures are installed on both sides of the door lock, when the handle 1 on one side of the door lock is pressed toward the inner end, the handle interlocking structure on that side moves to rotate the square core in an interlocking manner, and the first connecting part 3 on the other side rotates at the same time. However, since the width of the distal end of the first connecting groove 32 is larger than the diameter of the guide pin 5, the guide pin 5 does not move axially within the first connecting groove 32, and does not cause the second connecting part 4 and the handle 1 on the other side to move in an interlocking manner at the same time. This reduces the force required for unlocking and makes it easier for the user to unlock the door.

[0045] One side of the first connecting groove 32 has an inclined wall, while the other side has a flat surface parallel to the axial direction, which allows for unlocking and reduces the force required for unlocking. In another embodiment, the groove walls on both sides of the first connecting groove 32 may be configured as two inclined surfaces, but the width of the end of the first connecting groove 32 closest to the square core hole 31 must be equal to or less than the width of the end away from the square core hole 31, i.e., the width of the groove opening must be equal to or greater than the width of the groove bottom. In this case, when unlocking, the first connecting part 3 can be rotated by pressing the second connecting part 4. When the first connecting part 3 on the other side of the door lock rotates, the guide pin 5 remains stationary or moves toward the side closer to the square core, preventing the second connecting part 4 and handle 1 on that side from moving simultaneously. This also reduces the force required for unlocking compared to conventional door locks.

[0046] In yet another embodiment, the number of first sliding grooves 23 and first connecting grooves 32 may be one, and the distal end of the first connecting portion 3 may be cylindrical, so that the first connecting groove 32 has only one side end opening and one tip end opening. In this case, one end of the guide pin 5 is installed in the first sliding groove 23, and the other end abuts against the side end wall close to the axis of the first connecting groove 32, and the side wall of the guide pin 5 similarly abuts against the inclined groove wall of the first connecting groove 32. In this structure, when the second connecting portion 4 is pressed inward, the guide pin 5 can similarly rotate the first connecting portion 3 in conjunction with the first sliding groove 23.

[0047] In this embodiment, two second connecting grooves 41 for accommodating the guide pins 5 are symmetrically arranged along the circumferential direction at the inner end of the second connecting part 4, and the second connecting grooves 41 have their groove openings facing the first connecting part 3 and their groove walls abutting against the side surfaces of the guide pins 5. The second connecting grooves 41 can strengthen the tightness of the connection between the second connecting part 4 and the guide pins 5, and the shaft of the second connecting part 4 can be easily secured when in use. Week This can prevent rotation to some extent.

[0048] In addition, a return spring 6 is fitted around the outer periphery of the first connecting part 3, and the outer end of the return spring 6 abuts against the side surface of the guide pin 5 and the inner end is fixedly installed, for example, can abut against the inner end surface of the first position limiting part 21. When the second connecting part 4 is pushed toward the inner end to unlock, the guide pin 5 moves toward the inner end, compressing the return spring 6 at the same time as unlocking, completing unlocking, and after the second connecting part 4 loses its external force, the guide pin 5 pushes the second connecting part 4 back to its initial position due to the rebound of the return spring 6.

[0049] As in the first embodiment, a first sealing plate 71, a return torsion spring 8, and an elastic retaining ring for hole 28 are further installed on the inner end side of the fixed base 2. The method of connecting these with the fixed base 2 and the first connecting part 3 is the same as in the first embodiment, and therefore a description thereof will be omitted here.

[0050] Furthermore, when the groove walls on both sides of the first connecting groove 32 are parallel inclined surfaces, the return spring 6 can also return the first connecting part 3 to its initial state in conjunction with the guide pin 5 when it is pushed to move it to the outer end. Therefore, when the groove walls on both sides of the first connecting groove 32 are parallel inclined surfaces, only one of the return spring 6 and the return torsion spring 8 may be installed to indirectly return the first connecting part 3 and the second connecting part 4 to their initial states, or only a mechanism that can return the square core in the lock may be used.

[0051] In this embodiment, one end of the handle 1 (the right end in Fig. 10a) is fitted to the outer end side of the first position limiting portion 21 and abuts against the outer end surface of the second connecting portion 4, and can swing around the radial direction of the first connecting portion 3. Either by pushing the other end of the handle 1 (the upper end in Fig. 10a) toward the inner end or by pulling the other end of the handle 1 (the upper end in Fig. 10a) toward the outer end, the second connecting portion 4 can be slid toward the inner end, thereby realizing unlocking.

[0052] Specifically, a position limiting locking base 211 is provided on the outer periphery of one outer end of the first position limiting part 21, and an assembly hole 11 capable of accommodating the outer end of the second connecting part 4 and the outer end of the first position limiting part 21 is provided in the handle 1, and the assembly hole 11 is covered with a position limiting baffle 13, and a screw is provided on the outer periphery of the position limiting baffle 13 so that the position limiting baffle 13 can be fixedly connected to the handle 1. The position limiting baffle 13 is simultaneously fitted into the first position limiting part 21, and a position limiting hole 131 is provided in the position limiting baffle 13, the width of which is equal to or greater than the width of the position limiting locking base 211 and the length of which is shorter than the length of the position limiting locking base 211. Referring to Figures 10a and 10b, when the handle 1 and the handle interlocking structure are assembled, the outer end of the second connecting part 4 and the position limiting locking base 211 are both located within the assembly hole 11. Because the length of the position limiting locking base 211 is longer than the length of the position limiting hole 131, when assembling the position limiting locking base 211, first one end of the position limiting locking base 211 is inserted into the position limiting hole 131 and moved to that end so that the other end of the position limiting locking base 211 is positioned within the position limiting hole 131. At this time, the entire position limiting locking base 211 is passed through the position limiting hole 131, and then the position limiting baffle 13 is moved to fit into the first position limiting portion 21. By further fastening the position limiting baffle 13 to the handle 1 with a screw, the position limiting locking base 211 can be restricted within the assembly hole 11. In other words, one end of the handle 1 is fitted into the first position limiting portion 21 at this time. Because both the position limiting locking base 211 and the assembly hole 11 are non-circular, the handle 1 will not rotate around its axis after being fitted into the first position limiting portion 21.

[0053] In this embodiment, a position limiting groove 43 is provided on the outer end surface of the second connecting part 4, and a position limiting block 14 extending into the position limiting groove 43 is provided on the bottom surface of the assembly hole 11. The position limiting groove 43 and the position limiting block 14 are both elongated, and the longitudinal direction of both is parallel to the longitudinal direction of the handle 1, ensuring that the handle 1 can swing around the radial direction of the first connecting part 3 and also ensuring that the handle 1 can swing around the axis. WeekThe position limiting block 14 can also serve to limit the position of the second connecting portion 4, so that in use, the second connecting portion 4 moves axially around the outer periphery of the position limiting block 14 and does not move radially.

[0054] In this embodiment, an auxiliary plate 15 is further installed between the second connection part 4 and the bottom surface of the assembly hole 11, and the length of the auxiliary plate 15 is greater than the length of the second connection part 4 along the longitudinal direction of the handle 1. The auxiliary plate 15 is fitted into the position limiting block 14, with its two side surfaces abutting the end face of the second connection part 4 and the bottom surface of the assembly hole 11, respectively, and the length of the elongated hole in the middle of the auxiliary plate 15 is greater than the length of the position limiting block 14. When the handle 1 is pushed or pulled to swing it around the radial direction of the first connection part 3, the auxiliary plate 15 can move toward the fixed base 2, thereby increasing the area that receives the force of the second connection part 4, and thereby allowing it to stably move axially toward the fixed base 2, thereby achieving unlocking.

[0055] 12b, a positioning stopper 212 having the same shape as the position limiting hole 131 is installed on the side of the position limiting stopper 211 facing away from the handle 1. Therefore, after the assembly of the handle 1 and the handle interlocking structure is completed, the second connecting part 4 receives the biasing force of the return spring 6 and moves toward the handle 1, thereby indirectly interlocking the position limiting baffle 13 and moving it toward that side. At this time, the position limiting hole 131 can fit into the positioning stopper 212. Because the position limiting hole 131 is non-circular, this structure not only limits the rotation of the handle 1, but also improves the stability of the handle 1 and the handle interlocking structure.

[0056] In this embodiment, the outer end of the first position limiting part 21 is arc-shaped, i.e., the outer end surface of the position limiting locking base 211 is arc-shaped, and its middle position is closer to the bottom surface of the assembly hole 11 than to the outer periphery. In this structure, the assembly hole 11 has a small depth, so that the handle 1 and the fixed base 2 can be connected in a swingable manner.

[0057] The first position limiting portion 21 has a conical cylindrical structure, with the diameter of the end closest to the handle 1 being smaller than the diameter of the other end, which facilitates swinging of the handle 1 and improves the stability of the second connecting portion 4 within the first position limiting portion 21. In this embodiment, a second sealing plate 72 is further fitted to the first position limiting portion 21. The second sealing plate 72 is an annular plate with a circular hole in the middle whose cross section is the same as that of the first position limiting portion 21, and one side of the second sealing plate 72 is provided with a slit to form an opening that can be opened to fit into the first position limiting portion 21 during use, thereby shielding the position limiting baffle 13. The outer shape of the second sealing plate 72 may be the same as the shape of the assembly hole 11, and the second sealing plate 72 may be fitted into the assembly hole 11 during assembly of the handle assembly, so as to make the appearance of the handle 1 more unified and simple.

[0059] According to some embodiments of the present disclosure, all or some of the following advantages can be realized.

[0060] In the handle interlocking structure described in the present disclosure, the second connecting portion can push the guide pin to move it along the sliding groove to the inner end, and the side surface of the guide pin abuts on the inclined surface of the first connecting groove, and the guide pin is aligned with the axis. Week Since the first connecting part cannot rotate independently, the first connecting part is pushed and rotated by the guide pin, and therefore the inner end of the first connecting part rotates the square core of the lock in conjunction with the first connecting part, thereby realizing unlocking. Furthermore, if this handle interlocking structure is applied to a door lock, the handle is indirectly connected to the square core, and when the handle on one side of the door lock is pushed to move the second connecting part to the inner end to unlock it, the handle on the other side of the door lock does not move at the same time, thereby reducing the force required to unlock.

[0061] Furthermore, a V-shaped second connecting groove that abuts against the side of the guide pin is installed at the inner end of the second connecting part, and the guide pin is pushed to move along the sliding groove to the inner end by rotating the second connecting part clockwise or counterclockwise, thereby realizing unlocking. When applied to door locks, this increases the number of unlocking methods and provides users with a better unlocking experience.

[0062] Furthermore, in the handle assembly described in the present disclosure, the lower end of the handle is fitted into the outer end of the second position limiting portion or the first position limiting portion, and can swing radially along the second position limiting portion or the first position limiting portion, and the side surface abuts against the outer end of the second connecting portion, so that the second connecting portion can be moved to the inner end to achieve unlocking by either pushing the upper end of the handle inward or pulling it outward.

[0063] It will be apparent to those skilled in the art that the present disclosure is not limited to the details of the above exemplary embodiments, and that the present disclosure can be embodied in other specific forms without departing from the spirit or essential characteristics of the present disclosure. Therefore, in all respects, the embodiments should be considered as illustrative and not limiting, and the scope of the present disclosure is limited not by the above description but by the appended claims, and all changes within the meaning and scope of the claims are intended to be embraced. Any reference signs in the claims do not limit the scope of the associated claims. [Industrial Applicability]
