Description

Technical Field

[0001] The invention relates to the technical field of elevator accessories, and in particular to an asynchronous door-knife integrated car door lock and an elevator. Background Art

[0002] Traditional car door lock integrated door knives are divided into asynchronous door knives and synchronous door knives. Synchronous door knives are divided into inner clamping type and outer extension type, and the corresponding floor door locks can be upper hooks (locked from top to bottom) and inverted hooks (gravity locked from bottom to top). Upper hooks are generally compactly distributed on the two layers of door lock rollers, while inverted hooks are generally relatively far apart on the two layers of door lock rollers. When leveling, the door knife is located between the two layers of door lock rollers. Asynchronous door knives can only be inner clamping type, and the two layers of door lock rollers are distributed horizontally, or in an up-and-down diagonal distribution.

[0003] Compared with the synchronous door knife, the asynchronous door knife has a simpler structure. However, for elevator products with special configurations, for example, the floor door side uses a floor door lock that is only suitable for outward-opening synchronous door knife, but the car door side needs to use an asynchronous door knife, the existing car door system on the market cannot meet this configuration requirement and has certain application limitations. Summary of the invention

[0004] Based on this, it is necessary to provide an asynchronous door knife integrated car door lock and elevator, aiming to solve the problem that the existing technology uses a floor door lock that is only suitable for outward-type synchronous door knife on the floor door side and an asynchronous door knife on the car door side are incompatible.

[0005] On the one hand, the present application provides an asynchronous door-knife integrated car door lock, which includes:

[0006] A tying device, which is used to be installed on the door panel and can move with the door panel, and the tying device includes a base, a middle rod assembly, a right rod assembly and a connecting arm group, the middle rod assembly and the right rod assembly can be rotatably arranged on the base, and the middle rod assembly is connected to the right rod assembly through the connecting arm group;

[0007] a landing door lock assembly, the landing door lock assembly comprising a first landing door roller and a second landing door roller, the first landing door roller being capable of abutting against the middle rod assembly to unlock the landing door lock assembly, and the second landing door roller being capable of abutting against the right rod assembly; and

[0008] The car door lock assembly, the middle rod assembly can rotate under the drive of the first floor door roller and trigger the car door lock assembly to unlock.

[0009] The asynchronous door knife integrated car door lock of the above scheme is applied to the elevator, and is specifically installed on the car. When the car reaches the leveling position, the door knife is in a retracted state, and the first-floor door lock wheel and the second-floor door lock wheel both maintain a safe distance from the middle rod assembly and the right rod assembly. When the car door is ready to open, the tie device moves to the left with the door panel until the first-floor door roller is tangent to the middle rod assembly. Since the unlocking force of the car door lock assembly is less than the unlocking force of the floor door lock assembly, the car door continues to open, and the first-floor door roller squeezes the middle rod assembly and causes the middle rod assembly to rotate counterclockwise and squeeze the car door lock assembly. The car door lock assembly is disconnected, and the car door lock assembly is unlocked. At the same time, driven by the rotation of the middle rod assembly, the connecting arm assembly drives the right rod assembly to rotate to further reduce the distance from the second-floor door roller. The car door continues to move to the left. As the middle rod assembly and the right rod assembly move to the limit position, the middle rod assembly squeezes the first floor door roller to drive the floor door lock assembly to open. The second floor door roller contacts the right rod assembly. The tie device and the floor door lock assembly are relatively fixed, and the car door begins to open in conjunction with the floor door. The asynchronous door knife integrated car door lock of this solution realizes the compatibility of the floor door lock device using an external synchronous door knife and the car door lock device using an asynchronous door knife, which can meet the special configuration requirements of some elevator products and has strong applicability.

DETAILED DESCRIPTION

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0035] like Figures 1 to 7 As shown, an asynchronous door-knife integrated car door lock is shown in one embodiment of the present application, which includes: a locking device 10, which is used to be installed on a door panel and can move with the door panel; a floor door lock assembly 20 and a car door lock assembly 30.

[0036] The locking device 10 includes a base 11, a middle rod assembly 12, a right rod assembly 13 and a connecting arm group 14, wherein the middle rod assembly 12 and the right rod assembly 13 can be rotatably arranged on the base 11, and the middle rod assembly 12 is connected to the right rod assembly 13 through the connecting arm group 14; the floor door lock assembly 20 includes a first floor door roller 21 and a second floor door roller 22, wherein the first floor door roller 21 can contact with the middle rod assembly 12 to unlock the floor door lock assembly 20, and the second floor door roller 22 can contact with the right rod assembly 13; the middle rod assembly 12 can rotate under the drive of the first floor door roller 21 and trigger the car door lock assembly 30 to unlock.

[0037] In addition, the asynchronous door knife integrated car door lock further includes a left rod assembly 15, and the left rod assembly 15, the middle rod assembly 12 and the right rod assembly 13 are arranged at intervals in the horizontal direction. Among them, the first-layer door roller 21 is located between the left rod assembly 15 and the middle rod assembly 12, and the second-layer door roller 22 is located between the middle rod assembly 12 and the right rod assembly 13, and when the car door is closed, the first-layer door roller 21 and the second-layer door roller 22 respectively maintain a preset safety gap with the left rod assembly 15, the middle rod assembly 12 and the right rod assembly 13, so as to prevent the problem of accidentally touching the car door to open.

[0038] Please continue reading Fig. 9 In the present application, the floor door lock assembly 20 mainly includes a floor door lock seat 23 and a floor door lock hook 24. The floor door lock hook 24 is installed through a rotating shaft and can rotate clockwise or counterclockwise when subjected to force. The floor door lock hook 24 can be hooked and connected with the floor door lock seat 23 to keep the floor door lock assembly 20 locked. On the contrary, when the floor door lock hook 24 is separated from the floor door lock seat 23, the floor door lock assembly 20 is in an unlocked state.

[0039] In summary, the implementation of the technical solution of this embodiment will have the following beneficial effects: the asynchronous door knife integrated car door lock of the above solution is applied to the elevator, and is specifically installed on the car. When the car reaches the leveling position, the door knife is in a retracted state, and the first-floor door lock wheel and the second-floor door lock wheel are both kept at a safe distance from the middle rod assembly 12 and the right rod assembly 13. When the car door is ready to open, the tying device 10 moves to the left with the door panel until the first-floor door roller 21 is tangent to the middle rod assembly 12. Since the unlocking force of the car door lock assembly 30 is less than the unlocking force of the floor door lock assembly 20, the car door continues to open, and the first-floor door roller 21 squeezes the middle rod assembly 12 and causes the middle rod assembly 12 to rotate counterclockwise and squeeze the car door lock assembly 30. The car door lock assembly 30 is disconnected, and the car door lock assembly 30 is unlocked. At the same time, driven by the rotation of the middle rod assembly 12, the connecting arm assembly 14 drives the right rod assembly 13 to rotate to further reduce the distance from the second-floor door roller 22. The car door continues to move to the left. As the middle rod assembly 12 and the right rod assembly 13 move to the limit position, the middle rod assembly 12 squeezes the first floor door roller 21 to drive the floor door lock assembly 20 to open. The second floor door roller 22 conflicts with the right rod assembly 13. The coupling device 10 and the floor door lock assembly 20 are relatively fixed, and the car door begins to open in conjunction with the floor door. The asynchronous door knife integrated car door lock of this solution realizes the compatibility of the floor door lock device using the external synchronous door knife and the car door lock device using the asynchronous door knife, which can meet the special configuration requirements of some elevator products and has strong applicability.

[0040] Please continue reading Figure 8In some embodiments, the car door lock assembly 30 includes a car door lock hook 31, a switch plate 32 and a switch assembly 33. The car door lock hook 31 can be rotatably set on the base 11. The preset lock hook roller 311 on the car door lock hook 31 maintains a constant contact state with the middle rod assembly 12. The switch plate 32 is set on the car door lock hook 31, and the switch plate 32 can be triggered and cooperated with the switch assembly 33.

[0041] The switch plate 32 is an arc-shaped plate with a special-shaped structure, and its protruding part is arranged toward the switch assembly 33. The switch plate 32 is assembled with the car door lock hook 31 by any of the methods such as screw connection and snap connection, and the connection method is simple and reliable. When the door in the level car is opened, the first-floor door roller 21 squeezes the middle rod assembly 12 to rotate counterclockwise and push the car door lock hook 31 to lift, and the switch plate 32 will touch the switch assembly 33, so that the switch assembly 33 is disconnected and the car door lock assembly 30 is unlocked.

[0042] Specifically, in the above embodiment, the switch assembly 33 includes a cam switch 331, and the cam switch 331 includes an upper trigger roller 331a and a lower trigger roller 331b. When the car door lock hook 31 is lifted, the switch plate 32 presses against the upper trigger roller 331a to disconnect the car door lock assembly 30; when the car door lock hook 31 is locked, the switch plate 32 presses against the lower trigger roller 331b to close the car door lock assembly 30. Therefore, the switch plate 32 is driven by the car door lock hook 31 to move and switch between the upper and lower extreme positions, and can respectively contact with the upper trigger roller 331a or the lower trigger roller 331b to realize the control of the opening and closing state of the cam switch 331. The structure and working principle are simple, and the control accuracy of the cam switch 331 is high. Moreover, the upper trigger roller 331a and the lower trigger roller 331b are both in rolling contact with the switch plate 32, and the friction and wear are small, which is conducive to improving the service life of the equipment. Furthermore, since the convex portion of the switch plate 32 is in arc-surface rolling contact with the upper trigger roller 331 a and the lower trigger roller 331 b, the resistance is small, which can prevent interference with the up and down rotation of the car door lock hook 31 .

[0043] In addition, in some embodiments, the switch assembly 33 further includes a switch mounting seat 332, a fixed base 333 and an elastic telescopic unit, the cam switch 331 is arranged on the switch mounting seat 332, and the switch mounting seat 332 is elastically slidably connected to the fixed base 333 through the elastic telescopic unit. The fixed base 333 is used to load the switch mounting seat 332, and the switch mounting seat 332 is used to fix the cam switch 331 to ensure the stability of the overall structure of the switch assembly 33. The elastic telescopic unit provides the cam switch 331 with the degree of freedom of horizontal lateral reciprocating movement, and ensures that the cam switch 331 is in (elastic) flexible contact with the switch plate 32 to avoid extrusion deformation or even damage caused by rigid force.

[0044] Please continue reading Figure 8 For example, in the above embodiment, the elastic telescopic unit includes a sliding shaft 334, a spring 335 and a limit block 336. The sliding shaft 334 is arranged on the switch mounting seat 332 and slides through a preset hole on the fixed base 333. The spring 335 is sleeved on the sliding shaft 334 and abuts between the switch mounting seat 332 and the fixed base 333. The limit block 336 is arranged on the fixed base 333 and can abut against the switch mounting seat 332.

[0045] When the switch plate 32 contacts the cam switch 331, the cam switch 331 is pushed, and the sliding shaft 334 slides rightward in the preset hole to compress the spring 335, thereby realizing the elastic retreat of the cam switch 331. On the contrary, when the cam switch 331 loses the pushing force of the switch plate 32, the spring 335 automatically resets and releases the elastic force, pushing the sliding shaft 334 to slide leftward and reset. When it moves to the limit position, the limit block 336 will contact the switch mounting seat 332 to achieve positioning.

[0046] It should be noted that, for the switch assembly 33 of the car door lock assembly 30, as the car door lock hook 31 initially moves horizontally and retreats to the cam switch 331, under the reset action of the spring 335, the cam switch 331 abuts against the switch plate 32 until the car door lock hook 31 is lifted, and the switch plate 32 squeezes the upper trigger roller 331a, forcibly disconnecting the contact of the cam switch 331. The car door continues to open, and the switch plate 32 is completely separated from the two trigger rollers of the cam switch 331. Under the action of the limit block 336, the switch mounting seat 332 stops driving the cam switch 331 to move to the left, and waits for the switch plate 32 to squeeze the lower trigger roller 331b when the door is closed.

[0047] Please continue reading Figure 1In addition, based on any of the above embodiments, the middle rod assembly 12 includes a middle arm 121 and a middle rod 122, one end of the middle arm 121 is rotatably disposed on the base 11, and the other end is rotatably connected to one end of the middle rod 122, the right rod assembly 13 includes a right arm 131 and a right rod 132, one end of the right arm 131 is rotatably disposed on the base 11, and the other end is rotatably connected to one end of the right rod 132, the connecting arm group 14 includes a first connecting arm 141 and a second connecting arm 142, One end of the first connecting arm 141 is rotatably connected to the other end of the middle rod 122, one end of the second connecting arm 142 is rotatably connected to the other end of the right rod 132, and the other end of the first connecting arm 141 is rotatably connected to the other end of the second connecting arm 142; wherein, the first connecting arm 141 and the second connecting arm 142 are arranged at an angle, and when the middle rod 122 and the right rod 132 are close to each other, the angle decreases, and when the middle rod 122 and the right rod 132 are away from each other, the angle increases.

[0048] The middle arm 121 and the right arm 131 are used to install and support the middle rod 122 and the right rod 132, respectively, and provide the rotational freedom required by the middle rod 122 and the right rod 132. The first connecting arm 141 and the second connecting arm 142 realize the indirect connection of the middle rod 122 and the right rod 132 as a whole, so as to ensure that when the first-layer door roller 21 squeezes the middle rod 122 to rotate, the middle rod 122 can synchronously drive the right rod 132 to rotate through the first connecting arm 141 and the second connecting arm 142, so as to realize the linkage between the middle rod 122 and the right rod 132.

[0049] In addition, when the first-layer door roller 21 pushes the middle rod 122 to rotate and lift the car door lock to unlock the car door lock assembly 30, the middle arm 121 rotates synchronously and drives the connecting arm group 14 to rotate, the angle between the first connecting arm 141 and the second connecting arm 142 decreases, and the second connecting arm 142 drives the right arm 131 to rotate to make the right rod 132 and the left rod 152 closer, thereby further reducing the distance between the right rod 132 and the second-layer door roller 22.

[0050] Please continue reading Figure 1 Further, the middle rod assembly 12 further includes a middle rod limiting bolt 123, which is disposed on the base 11 and can be in limited contact with the middle arm 121, and the right rod 132 further includes a right rod limiting bolt 133, which is disposed on the base 11 and can be in limited contact with the right arm 131. The middle rod limiting bolt 123 is used to constrain the middle rod 122 from moving rightward, so as to limit the extreme running stroke of the middle rod 122 and ensure that the middle rod 122 can reliably contact the first-floor door roller 21 and the car door lock. The right rod limiting bolt 133 is used to constrain the right rod 132 from moving rightward.

[0051] In some embodiments, the left rod assembly 15 includes a left arm 151, a left rod 152 and a cross bar 153. One end of the left arm 151 is rotatably set on the base 11, and the other end is rotatably connected to the left rod 152. The cross bar 153 is fixed on the left rod 152, and the end of the cross bar 153 away from the left rod 152 is bent to form a hook body 153a. The hook body 153a can hook and pull the car door lock hook 31 to rotate so that the car door lock hook 31 is disconnected from the switch assembly 33 to achieve unlocking. When the personnel outside the hall use the triangular key to open the floor door lock assembly 20, the first floor door roller 21 is closer to the left rod 152, and the second floor door roller 22 is closer to the middle rod 122, and the floor door continues to be opened. At this time, the door opening force causes the first floor door roller 21 to touch the left rod 152, causing the left rod 152 to rotate counterclockwise, and the cross bar 153 moves synchronously with the left rod 152, the hook body 153a pulls up the car door lock hook 31, and the switch plate 32 squeezes the trigger roller 331a, forcing the contacts of the cam switch 331 to be disconnected.

[0052] Furthermore, the rotating shaft connecting the left arm 151 and the base 11 is set as a long axis, and the long axis is used to limit the rotation angle of the left rod 152; when the left rod 152 conflicts with the long axis of the left arm 151, the car door lock assembly 30 is completely unlocked, and the second-layer door roller 22 just contacts the middle rod 122, so that the first-layer door roller 21 and the second-layer door roller 22 jointly push the car door to open. The car door continues to open, and the switch plate 32 and the upper trigger roller 331a and the lower trigger roller 331b of the cam switch 331 are completely separated.

[0053] In addition, the left rod assembly 15 further includes a left rod limiting bolt 154, which is disposed on the base 11 and can be in limiting contact with the left rod 152. The left rod limiting bolt 154 is used to constrain the rightward movement of the left rod 152.

[0054] In addition, when the door is pried open from the car in a non-level area, without the action of the floor door lock assembly 20, the locking device 10 moves with the door panel for a distance until the car door lock hook 31 interferes with the car door lock seat 34, and the car door cannot continue to open, thereby realizing the door opening restriction function in the non-level area.

[0055] In addition to the above, the present application also provides an elevator, which includes the asynchronous door knife integrated car door lock as described in any of the above embodiments.
