Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a door lock installation structure for a discharge door of a construction elevator. Background Art

[0002] At present, the discharge doors of domestic construction elevators mostly use double-row doors. The double-row doors are composed of an upward door and a downward door. The upward door and the downward door are opened and closed in opposite directions, and the discharge door can be opened and closed quickly. The existing door lock usually adopts a hook that is rotated on the upward door. When the upward door and the downward door are closed, the hook is manually hung on the downward door to lock the door.

[0003] Due to the limitations of construction conditions, some construction sites must use single-row doors as discharge doors. Since this door lock is not suitable for single-row discharge doors, manual unlocking and locking are inefficient. It is urgent to design a convenient door lock structure that can automatically lock the door and unlock it with a foot. Utility Model Content

[0004] In order to solve the technical problem of low efficiency of manual unlocking and locking of existing devices, the utility model provides a door lock installation structure for a discharge door of a construction elevator with automatic door locking and foot-operated unlocking.

[0005] The technical solution adopted by the utility model to solve its technical problems is:

[0006] The door lock installation structure for the discharge door of a construction elevator includes a cage, a discharge door is arranged on one side of the cage, and a door lock is arranged between the discharge door and the cage. When the discharge door is fully closed, the door lock limits and locks the discharge door. The door lock includes a protrusion, a lock hook and a pedal component. The protrusion is fixedly arranged at the bottom of the discharge door, and a card slot is arranged on the protrusion. The lock hook is rotatably connected to the side of the cage. The lock hook includes a first end and a second end separated on both sides of the rotation connection point. The first end of the lock hook is located on one side of the protrusion, and a pedal component is provided below the second end of the lock hook. The pedal component is rotatably connected to the cage. The pedal component includes a pedal portion and a support portion separated on both sides of the rotation connection point. The side of the cage is provided with a first limit for limiting the second end from rotating toward one side of the pedal component. A second limiting portion is provided on the side of the cage for limiting the second end from rotating toward the discharge door, so that the second end has a tendency to rotate toward the side of the pedal component, driving the second end to lean on the first limiting portion, and the second end moves between the first limiting portion and the second limiting portion. Before the discharge door descends, the second end leans on the first limiting portion. When continuing to descend, the protrusion contacts the first end, and the second end rotates toward the discharge door until the first end is at least partially located in the slot. The second end leans on the first limiting portion, and the first end abuts against the slot to limit the upward movement of the discharge door. By stepping on the pedal, the support portion is driven upward, thereby driving the second end to rotate toward the discharge door, thereby causing the first end to disengage from the slot to complete the unlocking action.

[0007] Furthermore, the weight of the second end of the locking hook is greater than that of the first end, causing the second end to tend to rotate towards the side of the pedal member and driving the second end to lean against the limiting portion.

[0008] Furthermore, the second limiting portion is a limiting post, which is used to limit the rotation angle of the second end towards the side of the discharge door when the limiting post contacts the second end.

[0009] Furthermore, the weight of the supporting portion is greater than that of the pedal portion, driving the reset of the pedal member after being stepped on.

[0010] Furthermore, a spring is provided between the pedal member and the side portion of the cage, driving the reset of the pedal member after being stepped on.

[0011] Furthermore, the number of the card slots is at least one, which are arranged in sequence along the upward direction of the discharge door. The card slot includes a first side wall and a second side wall. The first side wall is horizontally arranged, and the second side wall is inclined relative to the horizontal plane. When the first end cooperates with the card slot, at least part of the projection of the first end perpendicular to the horizontal plane falls into the first side wall.

[0012] Furthermore, the number of the card slots is two.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1. The combination of automatic door locking and pedal unlocking: By designing the convex block, locking hook, pedal member, first limiting portion and second limiting portion, the automatic locking and convenient unlocking of the door lock are realized. When the discharge door is completely closed, the first end of the locking hook is located in the card slot on the convex block, and the upward movement of the discharge door is restricted by the abutment of the first end and the card slot, without manual intervention; when unlocking, only need to step on the pedal portion, drive the supporting portion to move upward, and then drive the second end to rotate towards the side of the discharge door, so that the first end disengages from the card slot, completing the unlocking action, improving the work efficiency and freeing the operator's hands.

[0015] 2. Gravity-assisted locking mechanism: The second end of the locking hook is designed to be heavier than the first end, enhancing the stability and reliability of the locking, and reducing the risk of failure. The locking hook can automatically return under the action of gravity, and the second end of the locking hook leans against the first limiting portion by the action of gravity, enabling the next automatic door locking to proceed smoothly. When the discharge door is closed in place, the locking hook will automatically align and embed into the card slot of the convex block, completing the locking without additional manual operation, improving the convenience and efficiency of the operation.

[0016] 3. The second limiting portion is a limiting post, which can effectively limit its excessive rotation towards the side of the discharge door, avoiding excessive swing of the locking hook during the unlocking process, the locking hook cannot return to its position, and affecting the smooth progress of the next automatic door locking.

[0017] 4. By making the weight of the support part greater than that of the pedal part, or by setting a spring between the pedal part and the side of the cage, the pedal part can be automatically reset after being stepped on, enabling the next unlocking to proceed smoothly.

[0018] 5. The multi-card slot design enhances stability: The number of card slots is at least one, and they are arranged in sequence along the upward direction of the discharge door, increasing the contact points between the locking hook and the bump, avoiding the failure risk faced by the door lock when a single card slot cannot be locked. The design of at least one card slot improves the fault tolerance rate and stability. The special shape of the card slot (the first side wall is horizontal and the second side wall is inclined) enables the locking hook to maintain a good locking state even when subjected to impact or vibration, enhancing the anti-interference ability of the entire system.

[0019] 6. Specifically, setting two card slots can not only improve the fault tolerance rate but also reduce the processing difficulty and production cost.

[0020] In summary, the door lock installation structure of this utility model not only simplifies the operation processes of locking and unlocking the door, improves work efficiency, but also ensures the safety and stability of the discharge door of the construction hoist through multiple design details.

[0028] Referring to Figures 1 to 2 , the present utility model provides a door lock installation structure for the discharge door of a construction elevator.

[0029] As Figures 1 to 2As shown in the figure, in the embodiment of this solution, the door lock installation structure for the discharge door of a construction elevator includes a cage 1. A discharge door 2 is provided on one side of the cage 1. A door lock is provided between the discharge door 2 and the cage 1. When the discharge door 2 is completely closed, the door lock limits and locks the discharge door 2. The door lock includes a convex block 3, a lock hook 4, and a foot-operated component 5. The convex block 3 is fixedly provided at the bottom end of the discharge door 2. A card slot 31 is provided on the convex block 3. The lock hook 4 is rotatably connected to the side of the cage 1. The lock hook 4 includes a first end 41 and a second end 42 that are located on both sides of the rotation connection point. The first end 41 of the lock hook 4 is located on one side of the convex block 3. Below the second end 42 of the lock hook 4 is the foot-operated component 5. The foot-operated component 5 is rotatably connected to the cage 1. The foot-operated component 5 includes a foot-operated part 51 and a support part 52 that are located on both sides of the rotation connection point. A first limit part 6 for restricting the second end 42 from rotating towards the foot-operated component 5 is provided on the side of the cage 1. A second limit part 7 for restricting the second end 42 from rotating towards the discharge door 2 is provided on the side of the cage 1. So that the second end 42 has a tendency to rotate towards the foot-operated component 5, driving the second end 42 to lean against the first limit part 6. The second end 42 moves between the first limit part 6 and the second limit part 7. Before the discharge door 2 descends, the second end 42 leans against the first limit part 7. When continuing to descend, the convex block 3 contacts the first end 41, and the second end 42 rotates towards the discharge door 2 side until at least part of the first end 41 is located in the card slot 31. The second end 42 leans against the first limit part 6. By abutting the first end 41 against the card slot 31, the upward movement of the discharge door 2 is restricted. By stepping on the foot-operated part 51, the support part 52 is driven to move upward, and then the second end 42 is driven to rotate towards the discharge door 2 side, so that the first end 41 disengages from the card slot 31, completing the unlocking action.

[0030] Regarding the design of the first end 41 and the second end 42 of the lock hook 4, it can be set that the weight of the second end 42 is greater than the weight of the first end 41, so that the second end 42 has a tendency to rotate towards the foot-operated component 5, driving the second end 42 to lean against the limit part 6; or the weights of both ends can be equal, and the second end 42 leans against the first limit part 6. A limit post is provided on the side of the second end 42 close to the discharge door 2 to prevent the lock hook 4 from not being able to return to its position, affecting the smooth progress of the next door-locking action; or the weights of the second end 42 and the first end 41 do not need to be considered. At this time, a limit part with elastic deformation ability is provided on the side of the second end 42 close to the discharge door 2, such as a compression spring is provided. On the one hand, it can ensure that the second end 42 leans against the first limit part 6, and on the other hand, it can enable the second end 42 to displace towards the discharge door 2 side to perform the door-locking action, and at the same time, it can also ensure the smooth progress of automatic door-locking.

[0031] It should be noted that, in order to ensure that the first end 41 can smoothly disengage from the slot 31, when the first end 41 is located in the slot 31, the bottom of the first end 41 does not contact the bottom of the slot 31, and the slot 31 reserves sufficient space to enable the first end 41 to rotate around the rotating connection point of the lock hook 4 and smoothly disengage from the slot 31 to complete the unlocking action.

[0032] In some embodiments, the second end 42 of the locking hook 4 is heavier than the first end 41 , so that the second end 42 tends to rotate toward the pedal component 5 , driving the second end 42 to lean against the first limiting portion 6 .

[0033] In some embodiments, the second limiting portion 7 is a limiting column, which is used to limit the rotation angle of the second end 42 toward the discharge door 2 when in contact with the second end 42 .

[0034] In some embodiments, the weight of the support portion 52 is greater than the weight of the pedal portion 51 , which facilitates the pedal member 5 to return to its original position after being stepped on.

[0035] In some embodiments, a spring is provided between the pedal component 5 and the side of the cage 1 to drive the pedal component 5 to return to its original position after being stepped on.

[0036] In some embodiments, there is at least one card slot 31, which is arranged in sequence along the upward direction of the discharge door 2. The card slot 31 includes a first side wall and a second side wall. The first side wall is horizontally arranged, and the second side wall is inclined relative to the horizontal plane. When the first end 41 is matched with the card slot 31, the projection of the first end 41 at least partially perpendicular to the horizontal plane falls into the first side wall.

[0037] There is at least one card slot 31, and they are arranged in sequence along the upward direction of the discharge door 2, which increases the contact points between the lock hook 4 and the protrusion 3, avoiding the risk of failure of the door lock when a single card slot 31 cannot be locked. The design of at least one card slot 31 improves the fault tolerance and stability. The special shape of the card slot 31 (the first side wall is horizontal and the second side wall is inclined) enables the lock hook 4 to maintain a good locking state when it is impacted or vibrated, enhancing the anti-interference ability of the entire system.

[0038] In some embodiments, there are two card slots 31. Providing two card slots 31 can improve the fault tolerance rate while reducing the processing difficulty and production cost.
