Technical Field

[0001] This invention relates to the field of elevator technology, and in particular to an integrated car door lock synchronous door knife. Background Technology

[0002] An elevator is a vertical lifting machine powered by an electric motor, equipped with a box-shaped cabin, used for transporting people or goods in multi-story buildings. As a vertical transportation tool, elevators have become an important building equipment in high-rise buildings and public places. With the significant increase in people's consumption levels, real estate developers have vigorously launched mid-to-high-end low-rise and high-rise residential buildings, driving the rapid growth of residential elevators and making it the main growth point of the entire elevator market.

[0003] With the increasing demands for elevator safety, elevator car door operators are generally equipped with door knife mechanisms, and corresponding door balls are installed on the landing doors. When the door knife mechanism clamps the door ball, the door operator can drive the landing doors to open and close together. Most existing door knife mechanisms use integrated car door lock door knives, and most door knives on the market are single-arm floating unlocking, which has poor safety. At the same time, in case of an emergency where the elevator cannot operate due to power failure or other reasons, rescue is more difficult. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an integrated car door lock synchronous door knife to solve the problem that the existing door knife mechanism is a single-arm floating unlocking, which has poor security, and the rescue is difficult when the elevator fails to operate due to power failure or other reasons.

The strike head bracket is used to open or close the positioning plate, the positioning plate is used to limit the swing of the lock hook swing arm, and the lock hook swing arm is used to drive the door knife mechanism to retract or extend the knife.

[0007] The door lock mechanism is opened or closed by a door knife mechanism when the lock hook swings. An emergency unlocking wire rope is provided on the door lock mechanism.

[0008] Preferably, the door knife mechanism includes a left blade and a right blade, which are rotatably connected by an upper swing arm and a lower swing arm. The upper swing arm and the lower swing arm are rotatably connected to the door knife base plate by a first rotating shaft and a second rotating shaft, respectively. A first spring and a first roller are installed on the right blade, and the other end of the first spring is fixedly connected to the door knife base plate.

[0009] Preferably, the positioning plate includes a trigger plate, which is rotatably connected to the door knife base plate via a third rotating shaft. A hook is fixedly connected to one end of the trigger plate, and a second spring is provided at the other end of the trigger plate. The other end of the second spring is fixedly connected to the door knife base plate, and a positioning groove is provided on the outer edge of the trigger plate near the second spring.

[0010] Preferably, the locking hook swing arm is fixedly connected to the first rotating shaft, a second roller is installed at the top of the locking hook swing arm, the second roller cooperates with the outer edge of the trigger plate, a first limiting shaft and a second limiting shaft are fixedly connected to one side of the locking hook swing arm, and a reset spring assembly is provided on the right side of the locking hook swing arm.

[0011] Preferably, a stop wheel is fixedly connected to the bottom plate of the door knife, and a stop groove corresponding to the stop wheel is provided on the left side of the lock hook swing arm.

[0012] Preferably, the door knife base plate is provided with a first arc-shaped groove and a second arc-shaped groove corresponding to the first limiting shaft and the second limiting shaft, and the first arc-shaped groove and the second arc-shaped groove are concentrically arranged with the first rotating shaft.

[0013] Preferably, the reset spring assembly includes a slide rod, one end of which is fitted with a third spring and fixedly connected to a fixing block, the other end of which passes through the door knife base plate, the slide rod being slidably connected to the door knife base plate, a positioning groove being provided on the left side of the fixing block, and a positioning post being fixedly connected to the right side of the lock hook swing arm, the positioning post being rotatably connected in the positioning groove.

[0014] Preferably, the impact head bracket includes a crossbar, one end of which passes through the door knife base plate and is fixedly connected to a rubber impact head, the crossbar is slidably connected to the door knife base plate, and the other end of the crossbar is fixedly connected to a vertical rod by a nut.

[0015] Preferably, the door lock mechanism includes a lock hook and a contact base fixing frame. The left side of the lock hook is rotatably connected to the door knife base plate via a fourth rotating shaft and is fixedly connected to a third limiting shaft. A fourth spring is installed on the third limiting shaft, and the other end of the fourth spring is fixedly connected to the door knife base plate.

[0016] Preferably, the bottom plate of the door knife has a through hole corresponding to the third limiting shaft, and the top end of the emergency unlocking wire rope is fixedly connected to the third limiting shaft.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, by using double-blade unlocking, when the door is close, the rubber bumper installed on the bumper bracket opens the positioning plate. The lock hook swing arm rotates to the right under the synchronous belt drive of the motor, and at the same time, the upper swing arm, lower swing arm, left blade and right blade move in conjunction. At this time, the elevator is running normally. When the door closes, the first roller on the right blade lifts the lock hook, and the contacts installed on the contact frame and the contacts on the contact seat frame open. At this time, the positioning plate locks the lock hook swing arm under the action of gravity and the second spring, thereby preventing the door knife from malfunctioning during operation, and the safety is high.

[0019] In the above solution, by installing an emergency unlocking steel wire rope on the door knife, when the elevator fails to operate due to power failure or other reasons and an emergency occurs, the positioning plate locks the hook arm to prevent the door knife from moving under the action of the reset spring assembly and the first roller on the right blade, so that the door knife and car door lock are always locked. At this time, the rescuers open the nearby landing door and pull the emergency unlocking steel wire rope fixed at a suitable position at the lower end of the car door panel to lift the lock hook and open the car door panel, reducing the difficulty of rescue.

A positioning post 42 is fixedly connected to the right side of the lock hook swing arm 3. The positioning post 42 is rotatably connected in the positioning groove 41.

[0049] This design allows the locking hook arm 3 to stretch the third spring 39 during swinging, and then reset through the restoring force of the third spring 39.

[0050] like Figure 4 and Figure 9 As shown, in this embodiment, the impact head bracket 7 includes a horizontal bar 43. One end of the horizontal bar 43 passes through the door knife base plate 1 and is fixedly connected to a rubber impact head 44. The horizontal bar 43 is slidably connected to the door knife base plate 1, and the other end of the horizontal bar 43 is fixedly connected to a vertical bar 45 through a nut 50.

[0051] When the door is nearing the closed position, the rubber bumper 44 mounted on the bumper bracket 7 will open the positioning plate 2.

[0052] like Figure 4 and Figure 8 As shown, in this embodiment, the door lock mechanism includes a lock hook 12 and a contact base fixing frame 11. The left side of the lock hook 12 is rotatably connected to the door knife base plate 1 via a fourth rotating shaft 46 and is fixedly connected to a third limiting shaft 47. A fourth spring 48 is installed on the third limiting shaft 47, and the other end of the fourth spring 48 is fixedly connected to the door knife base plate 1. A contact frame 9 is installed on the right side of the lock hook 12, and a contact base frame 10 is installed on the contact base fixing frame 11. A counterweight 13 is fixedly connected to the lower side of the lock hook 12, and its outer edge cooperates with the first roller 25.

[0053] When the left blade 5 and right blade 14 are in the retracted state, the first roller 25 mounted on the right blade 14 lifts the locking hook 12, and the contacts mounted on the contact frame 9 and the contacts mounted on the contact seat frame 10 open.

[0054] like Figure 4 and Figure 8 As shown, in this embodiment, the door knife base plate 1 has a through hole 49 corresponding to the third limiting shaft 47, and the top end of the emergency unlocking steel wire rope 15 is fixedly connected to the third limiting shaft 47.

[0055] This setup allows the emergency unlocking steel wire rope 15, which is fixed at a suitable position at the bottom of the car door panel, to be pulled, causing the lock hook 12 to be lifted, at which point the car door panel can be opened.

[0056] The technical solution provided by this invention, according to Figure 1 The door knife is assembled into a finished product as shown. All rotating parts are checked to ensure smooth, unobstructed rotation. The opening and closing dimensions are checked, and the door is controlled under different conditions. Figure 1-3The dimensions of the left blade 5 and right blade 14 are 34±1, 46±1 and 73±1, respectively. Then, the assembled door knife is installed on the corresponding door slide, and the corresponding position is adjusted and fixed. When the door knife is in the open state and the door is closed, the distance from the center line of the left blade 5 and right blade 14 to the center line of the entrance and exit is 150±2. Under the action of the lock hook 12 and the counterweight 13, the contact installed on the contact frame 9 and the contact seat installed on the contact seat frame 10 are engaged. After the contact and the contact seat are engaged, a gap of 6±1mm is maintained. The vertical engagement dimension of the lock hook 12 and the contact seat frame 10 is 13±1mm, and the horizontal gap is 6±2mm. Then, the contact seat frame 10 is fixed on the contact seat fixing frame 11. At this time, the door knife installation is completed.

[0057] Door knife open position Figure 3 As shown: Under the drive of the motor, the synchronous belt and the left blade 5 and right blade 14 move towards the closing position. When the door is close, the rubber bumper 44 installed on the bumper bracket 7 opens the positioning plate 2. The locking hook swing arm 3 rotates to the right under the drive of the motor synchronous belt, and at the same time, the upper swing arm 4, lower swing arm 6, left blade 5 and right blade 14 move in conjunction. At this time, the elevator is running normally.

[0058] Door knife closed state as follows Figure 2 As shown: Driven by the motor, the lock hook arm 3 rotates to the left, simultaneously moving the upper arm 4, lower arm 6, left blade 5, and right blade 14. The left blade 5 and right blade 14 are in a retracted state. At the same time, the first roller 25 installed on the right blade 14 lifts the lock hook 12, and the contacts installed on the contact frame 9 and the contacts on the contact seat frame 10 open. At this time, the positioning plate 2 locks the lock hook arm 3 under the action of gravity and the second spring 29 to prevent the door knife from malfunctioning during operation. Driven by the motor and the synchronous belt, the door knife moves in the opening direction, simultaneously moving the hall door together, and the door opens.

[0059] Emergency unlocking status, such as Figure 1 As shown: The door knife is equipped with an emergency unlocking steel wire rope 15. When the elevator fails to operate due to power failure or other reasons, and an emergency occurs, if the elevator is in the leveling area, the car door lock is in the unlocked state under the linkage of the landing door. The car door can be opened by professional personnel when it is in the hall door. If the car door is not in the opening area, under the action of the reset spring assembly 8 and the first roller 25 on the right blade 14, the positioning plate 2 locks the locking hook swing arm 3 to prevent the door knife from moving, so that the door knife and car door lock are always in the locked state. At this time, the car door can only be opened by rescue from outside the car door.

[0060] The procedure for opening the car door is as follows: rescue personnel open the nearby landing door, pull the emergency unlocking steel wire rope 15 fixed at a suitable position at the bottom of the car door panel to raise the lock hook 12, and then open the car door panel. It should be noted that emergency unlocking must be performed by professional personnel who are certified to work. Do not operate the door improperly or without a certificate.

[0061] The circuit type of the above scheme is an AC circuit, with a rated voltage of ≤ AC230V and a rated current of ≤ AC1.0A.

[0062] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.

[0063] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
