Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to an elevator door lock and an elevator door including the same. Background Art

[0002] Compared with the "Safety Code for the Manufacture and Installation of Lifts - Part 1: Passenger and Goods Lifts" GB / T 7588.1-2020, the "Safety Code for the Manufacture and Installation of Lifts" GB7588-2003 has been modified and many new contents have been added. Among them, the "Safety Code for the Manufacture and Installation of Lifts" GB7588-2003 has the following requirements for the use of contactors and contactor-type relays: the on and off of the contactor and relay on the elevator door need to be associated with the cooperation of the movable door lock and the fixed door lock. That is, as long as the movable door lock and the fixed door lock remain latched, the contactor and relay remain in contact so that the relay is in the conducting state. Once the movable door lock is disengaged from the fixed door lock, the contactor and relay separate so that the relay is in the off state, thereby providing important feedback for the elevator controller.

[0003] Compared with the "Safety Code for the Manufacture and Installation of Lifts" GB7588-2003, the "Safety Code for the Manufacture and Installation of Lifts - Part 1: Passenger and Goods Lifts" GB / T 7588.1-2020 puts forward further requirements: the contacts of the relay cannot be exposed or have potential safety hazards, and no part of the human body can directly touch the contacts of the relay to avoid electric shock or leakage.

[0004] There is an urgent need to improve the existing structure to implement the concept of safe production. Summary of the Utility Model

[0005] The utility model aims to provide an elevator door lock with better safety performance.

[0006] The elevator door lock according to the first aspect embodiment of the utility model includes:

[0007] A movable door lock assembly, which includes a first mounting plate and a rotating plate. The rotating plate is rotatably connected to the first mounting plate. One end of the rotating plate is provided with a hook portion. An unlocking mechanism is connected to the rotating plate at a position away from the hook portion. An extension plate is connected to the rotating plate above the hook portion. The extension plate is connected with a contact switch plug, and the contact switch plug is provided with pins;

[0008] A fixed door lock assembly is located on the moving path of the rotating plate, and the extension plate is closer to the fixed door lock assembly than the hook portion. The fixed door lock assembly includes a second mounting plate, a lock plate and a relay, and the lock plate and the relay are both fixedly connected to the second mounting plate, the lock plate has a horizontal section and an uphill section, the uphill section is closer to the rotating plate than the horizontal section, the horizontal section is connected to the upper end of the uphill section, the horizontal section is provided with a lock hole spaced apart from the uphill section, the hook portion is provided with a guide slope matching the uphill section, and the hook portion is used in conjunction with the lock hole; the relay is located above the lock plate, and contacts are provided in the relay, and an insertion port corresponding to the contacts is provided on the surface of the relay, the maximum pass size of the insertion port is smaller than the size of a human finger, and the position of the insertion port matches the position of the pin.

[0009] The elevator door lock according to the embodiment of the present invention has at least the following beneficial effects: in actual application, the movable door lock assembly is arranged on the door leaf of the elevator, and the fixed door lock assembly is arranged on the door lintel of the elevator. When the elevator door is closed, the door leaf can drive the movable door lock assembly to move in the direction close to the fixed door lock assembly until the hook of the rotating plate contacts the uphill section of the lock plate. Under the guidance of the inclined surface, the rotating plate gradually rises and drives the contact switch plug to move together. When the hook passes over the uphill section and enters the lock hole, the hook sinks into the lock hole under the action of gravity. At this time, the rotating plate rotates downward, and the pin of the contact switch plug passes through the corresponding The corresponding insertion port is inserted into the interior of the relay, thereby triggering the contacts of the relay; since the contacts of the relay are protected by the shell and are not exposed, and the maximum pass size of the insertion port is smaller than the size of a human hand, the human hand cannot directly touch the contacts of the relay, so as to improve the safety factor of elevator maintenance and prevent the elevator door from starting or electric shock and leakage due to false triggering; in addition, since the lock hole is arranged at intervals in the uphill section, even when the elevator door is subjected to violence in the door opening direction, the uphill section will not be deformed by the force of the hook, so as to ensure the integrity of the uphill section and avoid affecting the triggering of the relay due to deformation of the uphill section.

[0010] According to some embodiments of the present invention, in order to improve the docking accuracy between the pin and the insertion port, the pin is arranged on the lower bottom surface of the contact switch plug, and the lower bottom surface of the contact switch plug is a first inclined surface, and the first inclined surface has the same inclination trend as the uphill section.

[0011] According to some embodiments of the present utility model, correspondingly, the insertion port is provided on the upper surface of the relay, the upper surface of the relay is a second inclined plane, and the second inclined plane has the same inclination trend as the uphill section.

[0012] According to some embodiments of the present utility model, the slope of the first inclined plane is kept consistent with the slope of the second inclined plane. Since the number of the insertion pins and the number of the contacts are generally both two, keeping the slope of the first inclined plane consistent with the slope of the second inclined plane can satisfy the synchronous contact between the two insertion pins and the two contacts.

[0013] According to some embodiments of the present utility model, the extension plate has an inclined section, the contact switch plug is connected to the inclined section, and the relay is inclined with respect to the horizontal section. Since the extension plate has an inclined section and the relay is inclined with respect to the horizontal section, the present utility model can use a contact switch plug and a relay with a general design without separately designing their outer shapes.

[0014] According to some embodiments of the present utility model, for the convenience of installation and debugging, the relative position between the extension plate and the rotating plate is adjustable; the relative position between the relay and the second mounting plate is adjustable.

[0015] According to some embodiments of the present utility model, in order to limit the rotation path of the rotating plate, the first mounting plate is provided with a limiting pin on the rotation path of the rotating plate.

[0016] According to some embodiments of the present utility model, a return spring is connected between the first mounting plate and the rotating plate. Without the action of an external force, the return spring can limit the initial rotation position of the rotating plate to ensure that the rotating plate can avoid the uphill section of the locking plate through its hook portion.

[0017] According to some embodiments of the present utility model, the unlocking mechanism is provided with a connecting rod unit hinged to the rotating plate. When the elevator door needs to be opened, the connecting rod unit drives the rotating plate to rotate under the drive of an external force, so that the hook portion of the rotating plate can move upward away from the locking hole of the locking plate. At the same time, the insertion pins of the contact switch plug also leave the contacts of the relay to realize the unlocking of the elevator door.

[0018] According to the elevator door of the second aspect embodiment of the present utility model, it includes a door leaf, a door header and the above-mentioned elevator door lock, the movable door lock assembly is connected to the door leaf, and the fixed door lock assembly is connected to the door header.

[0019] The elevator door according to the embodiment of the present utility model has at least the following beneficial effects: Since the elevator door uses the elevator door lock, the elevator door complies with the relevant standards of "Safety Code for the Construction and Installation of Lifts - Part 1: Passenger and Goods Lifts" GB / T 7588.1-2020.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0028] In the description of the present utility model, it should be understood that for the orientation description, such as the orientation or positional relationship indicated by up, down, front, back, left, right, etc., is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model.

[0029] In the description of the present utility model, the meaning of several is one or more, the meaning of multiple is more than two, and understandings such as greater than, less than, exceeding, etc. do not include the present number, and understandings such as above, below, within, etc. include the present number. If there is a description of first and second, it is only for the purpose of distinguishing technical features and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features or implicitly indicating the sequence relationship of the indicated technical features.

[0030] In the description of the present utility model, unless otherwise clearly defined, words such as setting, installation, connection, etc. should be understood in a broad sense, and those skilled in the art can reasonably determine the specific meanings of the above words in the present utility model in combination with the specific content of the technical solution.

[0031] As Figures 1 to 4 shown, the elevator door lock according to the first aspect embodiment of the present utility model includes a movable door lock assembly 100 and a fixed door lock assembly 200. Among them, the movable door lock assembly 100 is installed on the door leaf of the elevator, and the fixed door lock assembly 200 is installed on the door lintel of the elevator. The door leaf can reciprocate along the guide rail under the drive of a power source, and the door lintel is fixedly arranged above the door leaf. When the elevator closes the door, the door leaf can drive the movable door lock assembly 100 to move towards the direction close to the fixed door lock assembly 200; when the elevator opens the door, the door leaf can drive the movable door lock assembly 100 to move towards the direction away from the fixed door lock assembly 200.

[0032] Specifically, the movable door lock assembly 100 includes a first mounting plate 110, a rotating plate 120, a contact switch plug 300 and an unlocking mechanism 400. The first mounting plate 110 is fixedly connected to the top of the door leaf by screws. The middle part of the rotating plate 120 is rotatably connected to the first mounting plate 110 through a bearing 111. One end of the rotating plate 120 is provided with a hook portion 121, and the tip of the hook portion 121 faces downward. For the convenience of description, the present utility model defines the direction in which the rotating plate 120 is provided with the hook portion 121 as the front direction, and the direction away from the hook portion 121 of the rotating plate 120 as the back direction.

[0033] The unlocking mechanism 400 can follow the existing technology and is provided with a link unit 410 driven by an electrical device. The rear end of the rotating plate 120 is hinged to the link unit 410, so that the rotating plate 120 can rotate around the bearing 111 under the drive of the electrical device. Since the unlocking mechanism 400 is provided with a link unit 410, and the link unit 410 can achieve long-distance transmission, the unlocking mechanism 400 can be fixedly connected to the middle or lower part of the door leaf by screws to be reasonably distributed on the door leaf.

[0034] Further, in order to limit the movement path of the rotating plate 120 and prevent it from colliding with other components of the elevator, the first mounting plate 110 is provided with a limit pin (not shown in the drawings) on the rotation path of the rotating plate 120. The limit pin is located above the rotating plate 120 to limit the upward rotation angle of the rotating plate 120. When the rotating plate 120 rotates upward to touch the limit pin, the rotating plate 120 cannot continue to rotate upward, thereby limiting the upward rotation angle of the unlocking mechanism 400 on the rotating plate 120. It can be understood that for the limitation of the upward or downward rotation angle of the rotating plate 120, in addition to setting limit components on the rotation path of the rotating plate 120, corresponding limit structures can also be set on the link unit 410 to meet different limiting requirements.

[0035] In order to reset the rotating plate 120, a return spring 112 is connected between the first mounting plate 110 and the rotating plate 120. When the rotating plate 120 rotates under the drive of the unlocking mechanism 400, since the position of the first mounting plate 110 is fixed, the return spring 112 is in an energy storage state. Once the unlocking mechanism 400 removes the acting force on the rotating plate 120, the return spring 112 releases its elastic force to reset the position of the rotating plate 120 and also reset the position of the unlocking mechanism 400 together to define the initial rotation position of the rotating plate 120.

[0036] In addition, an extension plate 130 is connected above the hook portion 121 of the rotating plate 120. The extension plate 130 extends to the front of the hook portion 121, so that the extension plate 130 can be closer to the fixed door lock assembly 200 relative to the hook portion 121. The lower bottom surface of the extension plate 130 is connected with the contact switch plug 300. The lower bottom surface of the contact switch plug 300 is provided with two pins 310, and the diameters of the two pins 310 are both not greater than 3 mm.

[0037] Correspondingly, the fixed door lock assembly 200 is located on the moving path of the turning plate 120. The fixed door lock assembly 200 includes a second mounting plate 210, a lock plate 220 and a relay 500. The second mounting plate 210 is fixedly connected to the door lintel by screws, and both the lock plate 220 and the relay 500 are fixedly connected to the second mounting plate 210. In order to comply with the relevant standards of "Safety Rules for the Construction and Installation of Lifts - Part 1: Passenger and Goods Lifts" GB / T 7588.1 - 2020, the relay 500 has contacts 510 with the same number as the pins 310 inside, and an insertion opening 520 corresponding to the contacts 510 is provided on the surface of the relay 500. The position of the insertion opening 520 matches the position of the pins 310, and the maximum passing size of the insertion opening 520 is not greater than 6 mm, that is, the maximum passing size of the insertion opening 520 is smaller than the size of a human finger, so that the human hand cannot directly touch the contacts 510 of the relay 500. Since the fixed door lock assembly 200 is installed on the door lintel of the elevator, it is easier for after-sales personnel to touch the vertical surface of the relay 500 during the maintenance process, but it is difficult to touch the upper surface of the relay 500. Therefore, the insertion opening 520 can be provided on the upper surface of the relay 500 to further reduce the risk of electric shock or leakage of electricity of the relay 500 to the human body.

[0038] Since the insertion opening 520 is provided on the upper surface of the relay 500, and the turning plate 120 has rotational freedom, in order to facilitate the contact switch plug 300 to trigger the relay 500 and improve the docking accuracy between the pins 310 and the insertion opening 520, a first inclined surface 330 and a second inclined surface 530 are respectively formed on the lower bottom surface of the contact switch plug 300 and the upper surface of the relay 500. Both the first inclined surface 330 and the second inclined surface 530 are inclined forward from bottom to top. Since the number of pins 310 and the number of contacts 510 are generally two, in order to ensure synchronous contact between the two pins 310 and the two contacts 510, the slope of the first inclined surface 330 is kept consistent with the slope of the second inclined surface 530.

[0039] Since both the contact switch plug 300 and the relay 500 are standard components and are generally purchased externally by the manufacturer, there is almost no special processing on the outer shapes of the contact switch plug 300 and the relay 500. In this regard, the relay 500 can be inclined and arranged on the second mounting plate 210 so that the upper surface of the relay 500 can form the second inclined surface 530. Moreover, the extension plate 130 is arranged to have an inclined section 131, and the inclined section 131 has the same inclination trend as the relay 500. The contact switch plug 300 is connected to the lower bottom surface of the inclined section 131 so that the lower bottom surface of the contact switch plug 300 can form the first inclined surface 330.

[0040] As Figure 2 and Figure 3 shown, in order to make the on / off of the contact switch plug 300 and the relay 500 be associated with the cooperation between the rotating plate 120 and the locking plate 220, the locking plate 220 is located below the relay 500, and the locking plate 220 is closer to the rotating plate 120 than the relay 500. The locking plate 220 has a horizontal section 221 and an uphill section 222. The uphill section 222 is closer to the rotating plate 120 than the horizontal section 221. The uphill section 222 is inclined forward from bottom to top. The horizontal section 221 is connected to the upper end of the uphill section 222. The horizontal section 221 is provided with a locking hole 223 spaced from the uphill section 222. The hook portion 121 is provided with a guiding inclined surface 122 matching the uphill section 222, and the hook portion 121 and the locking hole 223 are used in cooperation.

[0041] With the above structure, when the elevator door closes, the door leaf drives the movable door lock assembly 100 to move towards the fixed door lock assembly 200 until the hook portion 121 of the rotating plate 120 contacts the uphill section 222 of the locking plate 220. Under the guiding action of the inclined surface, the rotating plate 120 is gradually lifted upwards. At this time, the return spring 112 is in an energy storage state. The rotating plate 120 drives the contact switch plug 300 to move together. When the hook portion 121 crosses the uphill section 222 and enters the locking hole 223, under the action of the return spring 112 and gravity, the hook portion 121 falls into the locking hole 223. At this time, the rotating plate 120 rotates downwards, and the pin 310 of the contact switch plug 300 is inserted into the interior of the relay 500 through the corresponding insertion port 520 along the trend, thereby triggering the contact 510 of the relay 500.

[0042] When the elevator door opens, the rotating plate 120 rotates upward under the drive of the unlocking mechanism 400, enabling the hook portion 121 to leave the lock hole 223. At this time, the return spring 112 is in an energy storage state. Meanwhile, the pin 310 of the contact switch plug 300 also leaves the contact 510 of the relay 500 to unlock the elevator door. Subsequently, the door leaf drives the movable door lock assembly 100 to move away from the fixed door lock assembly 200 until the door leaf is opened to the limit position. Once the unlocking mechanism 400 removes the force on the rotating plate 120, the return spring 112 releases its elastic force to reset the position of the rotating plate 120 and, together with the position of the unlocking mechanism 400, to limit the initial rotation position of the rotating plate 120, thereby ensuring that the rotating plate 120 can avoid the uphill section 222 of the lock plate 220 through its hook portion 121 and preventing interference between the hook portion 121 and the uphill section 222.

[0043] Compared with the prior art, since the contacts 510 of the relay 500 are protected by the housing and not exposed, and the maximum passing size of the insertion port 520 is smaller than the size of a human hand, a human hand cannot directly touch the contacts 510 of the relay 500, thus improving the safety factor of elevator maintenance and preventing the occurrence of situations such as the elevator door being activated due to accidental triggering or electric shock and leakage. In addition, since the lock holes 223 are spaced apart on the uphill section 222, even when the elevator door is subjected to violence in the opening direction, the uphill section 222 will not deform due to the force of the hook portion 121, ensuring the integrity of the uphill section 222 and preventing the triggering of the relay 500 from being affected by the deformation of the uphill section 222.

[0044] Assume that the lock plate 220 only has the uphill section 222. After the hook portion 121 crosses the uphill section 222, the hook portion 121 will immediately fall into the vacant position in front of the uphill section 222. Although at this time the uphill section 222 can provide a limit for the backward movement of the hook portion 121, when the elevator door is subjected to violence in the opening direction, the uphill section 222 may be deformed due to the force of the hook portion 121. After experiencing further violent door-opening actions, the uphill section 222 may even be forcibly flattened by the hook portion 121, and then lose the locking function for the hook portion 121. Since the lock hole 223 of the present invention is arranged at an interval from the uphill section 222, when the elevator door is subjected to violence in the opening direction, the force of the hook portion 121 is mainly concentrated on the lock hole 223 and will not affect the uphill section 222. And because the strength of the lock hole 223 is much greater than the strength of the uphill section 222, the present invention can better maintain the locked state of the elevator door and prevent the elevator door from being forcibly opened.

[0045] As Figure 2 and Figure 4 shown, for the convenience of installation and debugging, the relative position between the extension plate 130 and the rotating plate 120 is adjustable, and the relative position between the relay 500 and the second mounting plate 210 is adjustable. Specifically, the extension plate 130 or the rotating plate 120 is provided with a waist-shaped hole 123, and the installer can adjust the front and rear position of the extension plate 130 on the rotating plate 120 through a screw and the waist-shaped hole 123, so as to adjust the front and rear position of the contact switch plug 300. At the same time, the relay 500 or the second mounting plate 210 is provided with an arc-shaped hole 540, and the installer can adjust the angle of the relay 500 on the second mounting plate 210 through a screw and the arc-shaped hole 540, so that the position of the relay 500 can correspond to the position of the contact switch plug 300 to adapt to different elevator working conditions. Once the contact switch plug 300 and the relay 500 are installed and debugged, unless the spare parts are replaced or a major accident occurs, the relative positions of the two on the corresponding mounting carriers will no longer change.

[0046] According to the elevator door of the second aspect embodiment of the present utility model, it includes the elevator door lock according to the first aspect embodiment of the present utility model above, and further includes a door leaf (not shown in the drawings) and a door lintel (not shown in the drawings). The first mounting plate 110 is fixedly connected to the top of the door leaf by screws, the unlocking mechanism 400 is fixedly connected to the middle or lower part of the door leaf by screws, and the second mounting plate 210 is fixedly connected to the door lintel by screws. Since the door leaf can move relative to the door lintel, when the elevator door closes, the door leaf can drive the movable door lock assembly 100 to move towards the fixed door lock assembly 200; when the elevator door opens, the door leaf can drive the movable door lock assembly 100 to move away from the fixed door lock assembly 200.

[0047] In view of the fact that elevator doors are divided into single-leaf doors and double-leaf doors, for a single-leaf door, the number of the fixed door lock assemblies 200 and the number of the movable door lock assemblies 100 only need to be set to one. For a double-leaf door, its two door leaves move synchronously through a transmission belt. Although each door leaf is provided with a movable door lock and the door lintel is correspondingly provided with two fixed door locks, the number of the hook parts 121 and the number of the lock holes 223 only need to be set to one. One of the movable door locks follows the structure of the movable door lock assembly 100, and the other movable door lock only needs to be provided with the contact switch plug 300 without the rotating plate 120; one of the fixed door locks follows the structure of the fixed door lock assembly 200, and the other fixed door lock only needs to be provided with the relay 500 without the lock plate 220.

[0048] Since the elevator door adopts the elevator door lock, the elevator door complies with the relevant standards of "Safety Rules for the Construction and Installation of Lifts - Part 1: Passenger and Goods Lifts" GB / T 7588.1-2020.

[0049] The above has described the embodiments of the present utility model in detail with reference to the drawings, but the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the technical field, various changes can be made without departing from the gist of the present utility model.
