Description

Technical Field

[0001] The present invention relates to the technical field of locks, and in particular to a latch assembly and a lock. Background Art

[0002] In a lock, the handle is usually linked to the bolt assembly through a square core and a peach. Specifically, the rotation of the handle can drive the square core to rotate, and the square core then drives the peach to rotate. The paddle block on the periphery of the peach pushes the relevant components in the bolt assembly to move, and finally unlocks the lock. The role of the peach is to convert the movement form of the square core into another movement form that can be linked to the bolt assembly. For example, the input end of the peach (the part connected to the square core) is rotation, and the output end of the peach (the part connected to the bolt assembly) is swinging. However, when this type of peach structure is used, the user can only unlock the lock by turning the handle, and the unlocking method is relatively simple. Summary of the invention

[0032] In this embodiment, a peach assembly and a lock having the same are disclosed. Figure 1a and Figure 1b The three-dimensional structure of the peach assembly at two different viewing angles is shown; Figure 2 The exploded structure of the peach assembly is shown; Figure 3 The structure of the lock with the peach assembly is shown, in which only the structure related to the peach assembly and the transmission connection with it are shown, and the structures in other locks are not the innovation points of this application, so they are not shown in the figure. Please refer to Figures 1a to 3 The peach assembly includes: a first drive plate 11, a second drive plate 12, a third drive plate 13, a fourth drive plate 14 and two drive posts 15. The four drive plates are mutually engaged, and the middle part encloses a first cavity 16 that can accommodate the square core. The two ends of the four drive plates respectively enclose two second cavities 17 that accommodate the drive posts 15. The outer periphery of the drive posts 15 is provided with a paddle head 151 inserted into the drive plate. When the middle square core rotates or moves radially (i.e. swings), the four drive plates can be moved toward the outer periphery respectively, and the directions of the four drive plates moving outward are fixed. If any one of the drive plates is used as the output end, it can be realized that when the square core moves or swings, the output end moves in a fixed manner in a single direction.

[0033] Please combine Figure 2 Specifically, the first driving plate 11 is a U-shaped structure, and a first card slot 21 and a second card slot 22 are provided in the middle along the X-axis direction in the figure. The opening directions of the two are facing the positive direction of the X-axis, and are respectively used for engaging and assembling with the second driving plate 12 and the third driving plate 13; first shifting holes 31 are provided at both ends of the first driving plate 11 along the Y-axis direction, which are used to connect with the shifting head 151 on the driving column 15.

[0034] The second driving plate 12 is a Z-shaped structure, in which a third slot 23 and a fourth slot 24 are provided in the middle along the X-axis direction in the figure, and the opening directions of the two are toward the negative direction of the X-axis. When assembled, the third slot 23 is clamped on the first slot 21, and the middle part of the second driving plate 12 is in the middle position of the first driving plate 11. The first driving plate 11 can move along the Z-axis direction, and the second driving plate 12 can move along the Y-axis direction; second shifting holes 32 are provided at both ends of the second driving plate 12 along the Z-axis direction for connecting with the shifting head 151 on the driving column 15.

[0035] The third driving plate 13 is also a Z-shaped structure, which is symmetrically arranged with the second driving plate 12. A fifth card slot 25 and a sixth card slot 26 are provided in the middle of the third driving plate 13 along the X-axis direction, wherein the fifth card slot 25 faces the positive direction of the X-axis and engages with the fourth card slot 24, and the sixth card slot 26 faces the negative direction of the X-axis and engages with the second card slot 22. Through these two card slots, the third driving plate 13 can be assembled with the first driving plate 11 and the second driving plate 12 and can also be moved along the Y-axis direction; third shifting holes 33 are provided at both ends of the third driving plate 13 along the Z-axis direction for connecting with the shifting head 151 on the driving column 15.

[0036] The fourth drive plate 14 is a U-shaped structure facing the opening of the first drive plate 11, and a baffle 141 extending to the middle of the second drive plate 12 and the third drive plate 13 is provided in the middle thereof, and fourth shifting holes 34 are provided at both ends thereof along the Y-axis direction for connecting with the shifting head 151 on the drive column 15. The two ends of the fourth drive plate 14 are arranged on both sides of the second drive plate 12 and the third drive plate 13. Figure 1a and Figure 1b The baffle plate 141 and the middle parts of the first drive plate 11, the second drive plate 12 and the third drive plate 13 can form a first cavity 16 for inserting the square core. During assembly, the square core is inserted into the first cavity 16; the two ends of the first drive plate 11, the second drive plate 12, the third drive plate 13 and the fourth drive plate 14 respectively form two second cavities 17, which are used to accommodate the drive column 15 respectively.

[0037] The driving column 15 is rotatably disposed in the second cavity 17 , and four shifting heads 151 are disposed on its periphery and inserted into the first shifting hole 31 , the second shifting hole 32 , the third shifting hole 33 and the fourth shifting hole 34 respectively to realize the transmission between the driving column 15 and the four driving plates.

[0038] When in use, if the square core rotates, it can drive the first drive plate 11 to move along the positive direction of the Z axis, drive the second drive plate 12 to move along the negative direction of the Y axis, drive the third drive plate 13 to move along the positive direction of the Y axis, and drive the fourth drive plate 14 to move along the negative direction of the Z axis. That is, when the square core rotates, it can drive the four drive plates to move in a fixed direction respectively. At this time, any drive plate can be used as an output end; if the square core moves in any direction of its own radial direction, for example, Figure 2 The Y axis moves in the positive direction, which will drive the third driving plate 13 to move in the positive direction along the Y axis. The third shifting hole 33 on the third driving plate 13 can drive Figure 1a The driving column 15 on the right side of the middle rotates clockwise to drive Figure 1a The driving column 15 on the left side of the center rotates counterclockwise, and then the dial head 151 on the driving column 15 can drive the first driving plate 11 to move along the positive direction of the Z axis, drive the second driving plate 12 to move along the negative direction of the Y axis, and drive the fourth driving plate 14 to move along the negative direction of the Z axis, that is, when the square core moves along the positive direction of the Y axis, it can drive the four driving plates to move in a fixed direction. At this time, any driving plate can be used as an output end; similarly, the square core moves along the Z axis direction, the negative direction of the Y axis, or along the XY axis directions at the same time, which can make the four driving plates move in a fixed direction. Finally, it is achieved that when the square core moves or swings, the output end moves in a fixed manner in a single direction. When applied to locks, the user can drive the peach assembly to move in a fixed manner by rotating or swinging the handle in any direction.

[0039] As can be seen from the accompanying drawings, in this embodiment, the middle parts of the first drive plate 11, the second drive plate 12, the third drive plate 13 and the fourth drive plate 14 are respectively perpendicular to their two ends. This structure is the best structure for the transmission cooperation between the four drive plates and the square core. Of course, after adjusting the angle between the middle parts and the two ends of the four drive plates, for example, setting the middle part to an inclined structure, the cross-sectional shape of the square core is changed accordingly. It can also be inserted into the first cavity 16 and realize transmission connection with the four drive plates.

[0040] In this embodiment, six card slots are provided on the first drive plate 11, the second drive plate 12 and the third drive plate 13. The three drive plates can be snapped together through the six card slots, which can reduce the width of the three together along the X-axis direction, forming a smaller structure. The fourth drive plate 14 is further provided on its periphery, forming a smaller peach assembly as a whole, which is convenient for installation and use in the lock. At the same time, this structural form can also make the width of each side wall of the first cavity 16 and the second cavity 17 along the X-axis direction relatively large, ensuring that the transmission of the square core, the drive column 15 and each drive plate is more stable. In other embodiments, these card slots may not be provided, but along Figure 2 Arrange the four drive plates in sequence in the middle X-axis direction to form the first cavity 16 and the second cavity 17, and cooperate with the two drive columns 15 to make the four drive plates move in a fixed direction when operating the square core. Alternatively, only a long slot is provided in the middle of each drive plate, and the three drive plates can also be assembled together.

[0041] In this embodiment, the first drive plate 11, the second drive plate 12, the third drive plate 13 and the fourth drive plate 14 have the same width along the depth direction of the first cavity 16 (the X-axis direction in the figure). On the one hand, this structure can reduce the overall volume of the peach assembly, and on the other hand, when it is installed in the lock, the whole has better stability and will not shake along the X-axis direction. It should be noted that in the lock described later, a slider 18 is also provided on the side of each drive plate, and the width here does not include the thickness of these sliders 18, but is only the width of each drive plate body, and when it is installed in the lock, the width is equal to the distance between the front and rear inner walls of the lock housing 41.

[0042] In addition, in this embodiment, the fourth driving plate 14 is further used as the output end of the peach assembly, so the fourth shifting hole 34 on the fourth driving plate 14 is also set as a long hole, and the side of the shifting head 151 inserted therein abuts against the side close to the moving direction of the fourth driving plate 14. Figure 2As shown, the fourth drive plate 14 moves downward (negative direction of the Z axis) when in use, and accordingly, the side of the dial head 151 abuts against the lower side of the fourth dial hole 34. If in use, only the square core is moved toward the side of the fourth drive plate 14, then the fourth drive plate 14 can be directly pushed to move downward, and the fourth dial hole 34 will not drive the dial head 151 to move downward, and accordingly, the first drive plate 11, the second drive plate 12 and the third drive plate 13 will not move at the same time, which reduces the external force required to drive the output end to move to a certain extent. In addition, when the square core is rotated or moved toward the first drive plate 11, the second drive plate 12 or the third drive plate 13, the fourth drive plate 14 can still be driven to move downward.

[0043] Furthermore, in this embodiment, the first shifting hole 31 is also configured as a long strip hole, and the side surface of the shifting head 151 inserted therein abuts against the side away from the moving direction of the first driving plate 11 ( Figure 2 the second dial hole 32 is also set as a long hole, the side of the dial head 151 inserted therein abuts against the side away from the moving direction of the second drive plate 12 ( Figure 2 the third dial hole 33 is set as a long hole, the side of the dial head 151 inserted therein abuts against the side away from the moving direction of the third drive plate 13 ( Figure 2 In this structure, when the square core drives any one of the first drive plate 11, the second drive plate 12 and the third drive plate 13 to move, the drive column 15 will only drive the fourth drive plate 14 to move, and the other two drive plates will not move at the same time, further reducing the external force required to drive the output end to move. It should be noted that according to this rule, in other embodiments, any one of the drive plates can be used as the output end, and the side position of the dial head 151 abutting against each drive plate can be adjusted accordingly, so that each of the above-mentioned drive plates can also achieve a relatively independent movement mode.

[0044] In addition, in this embodiment, a lock using the above-mentioned peach assembly is also disclosed. Figure 3 The lock comprises a housing 41, a bolt assembly and a peach assembly arranged therein. A through hole facing the first cavity 16 of the peach assembly is provided on the side of the housing 41 for inserting the square core. The bolt assembly is transmission-connected to the fourth drive plate 14, so as to directly or indirectly control the opening and closing of the bolt assembly.

[0045] The two ends of the driving column 15 in the peach assembly are rotatably connected to the inner wall of the shell 41. Specifically, a rotating shaft 152 with a diameter smaller than the driving column 15 body is provided at both ends of the driving column 15, and a through hole facing the rotating shaft 152 is provided on the inner wall of the shell 41. The driving column 15 is rotatably connected to the inner wall of the shell 41 by inserting the rotating shaft 152 into the through hole.

[0046] The first drive plate 11, the second drive plate 12, the third drive plate 13 and the fourth drive plate 14 in the peach assembly are slidably disposed in the housing 41, and the sliding directions of adjacent drive plates are perpendicular to each other. Figure 3 As shown, the sides of the first drive plate 11, the second drive plate 12, the third drive plate 13 and the fourth drive plate 14 are all provided with sliders 18, and the sliders 18 are slidably arranged in the sliding holes on the housing 41 to achieve the sliding connection between the drive plate and the housing 41. Specifically, the first drive plate 11 and the fourth drive plate 14 are arranged along Figure 3 The second drive plate 12 and the third drive plate 13 move in the Y-axis direction. Figure 3 The fourth drive plate 14 is connected to the locking tongue assembly as an output end.

[0047] In this embodiment, the lock tongue assembly uses a flip tongue as the lock tongue 42, and limits the movement of the flip tongue through a limit rod 43, thereby controlling the opening and closing of the lock tongue assembly. The fourth drive plate 14 controls the movement of the limit rod 43 through a transmission rod 44, thereby indirectly controlling the lock tongue assembly. Specifically, the middle part of the limit rod 43 is rotatably arranged in the housing 41, and one end of the limit rod 43 can be rotated to the inner side of the lock tongue 42 during rotation, thereby limiting the flipping of the lock tongue 42, thereby locking the lock tongue assembly. When the end of the limit rod 43 is rotated to the outer side of the lock tongue 42, the restriction on the lock tongue 42 can be released, and the lock tongue 42 can be flipped freely. The lock tongue assembly composed of the flip tongue is a prior art, and the specific structure and principle are not repeated here.

[0048] A return spring 45 is also provided in the housing 41, which applies a force to the limit rod 43 so that one end of the limit rod 43 is located inside the lock tongue 42. Only when the limit rod 43 is subjected to an external force and overcomes the force of the return spring 45, can one end of the limit rod 43 be rotated to the outside of the lock tongue 42. Figure 3 As shown, the return spring 45 is a torsion spring in this embodiment, which is sleeved on the rotating shaft in the middle of the limit rod 43, with one end abutting against the inner wall of the shell 41 and the other end abutting against the limit rod 43, thereby applying a force to the limit rod 43 to make the limit rod 43 generate a rotation axis. Figure 3 The locking rod 42 has a tendency to rotate clockwise so that the upper end of the limiting rod 43 is rotated to the inner side of the locking tongue 42.

[0049] The transmission rod 44 is arranged between the fourth drive plate 14 and the limit rod 43, the middle of which is rotatably arranged in the housing 41, the right end of which is connected to the front end of the fourth drive plate 14 (negative direction of the Z axis in the figure), and the left end of which is connected to the other end of the limit rod 43. Figure 3When the middle Z axis moves in the negative direction, the transmission rod 44 can be driven to rotate clockwise, and then the limiting rod 43 can be driven to rotate counterclockwise, so that the upper end of the transmission rod 44 moves to the outside of the lock tongue 42, thereby releasing the limit on the lock tongue 42, that is, releasing the lock of the lock tongue assembly; thereafter, after the peach assembly is not subjected to external force, the return spring 45 drives the limiting rod 43 to rotate clockwise, and then drives the transmission rod 44 to rotate counterclockwise, which can drive the fourth drive plate 14 to move in the positive direction of the Z axis. At this time, if one or more of the first drive plate 11, the second drive plate 12 or the third drive plate 13 have moved before, they can be restored to the initial state of the peach assembly under the drive of the drive column 15.

[0050] It should be noted that the fourth drive plate 14 is used as the output end of the peach assembly and is connected to the bolt assembly in a transmission manner to control the bolt assembly. In other embodiments, no matter whether the prying hole is a long hole or not, any one of the other drive plates can be used as the output end, and the above-mentioned effect of transmission with the bolt assembly can also be achieved.

[0051] It should also be noted that, in this embodiment, the transmission rod 44 and the limit rod 43 are indirectly used to limit whether the lock tongue 42 can be turned over, thereby realizing the control of the opening and closing of the lock tongue assembly. In other embodiments, the fourth drive plate 14 or other output ends can also be directly connected to the lock tongue assembly. When the fourth drive plate 14 moves under the action of the square core, the lock tongue 42 is driven to shrink into the housing 41, and the lock tongue assembly can also be controlled by the peach assembly.

[0052] In addition, in this embodiment, a first slide plate 51 extending outward and abutting against the inner wall of the housing 41 is provided in the middle of the first drive plate 11, and a second slide plate 52 abutting against the inner wall of the housing 41 is provided in the middle of the fourth drive plate 14. The provision of the first slide plate 51 and the second slide plate 52 can improve the sliding stability of the first drive plate 11 and the fourth drive plate 14 in the housing 41.

[0053] When the lock in this embodiment is in use, the square core of the handle is inserted into the first cavity 16. The user can rotate or swing the square core radially to move the fourth drive plate 14 downward, thereby driving the transmission rod 44 and the limit rod 43 to control the opening and closing of the lock tongue assembly. When it is applied to the door, the user can open the door by rotating or swinging the handle in any direction. The lock is adapted to the handle unlocking action of different operation modes, making the lock widely applicable. No matter what kind of unlocking action the user takes, it can be conveniently unlocked adaptively. It is suitable for family scenes with multiple family members, and more suitable for public places, with better user experience.

[0054] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
