Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of elevator door lock device, in particular to a right door lock assembly for elevator. BACKGROUND

[0002] The elevator landing door lock, also known as the hall door lock, is installed at the landing door of each floor, and is a safety device for ensuring that the landing door cannot be opened by people outside the hall. Only when the elevator enters the unlocking area and stops at the landing can the landing door be opened synchronously by the door blade on the car door. In an emergency or when maintenance personnel need to enter the shaft or maintain the elevator on the car roof, the landing door can be opened from outside the landing door by trained elevator professionals using a triangular key. When opening the landing door from outside the landing door with a triangular key, safety operation specifications must be followed. For example, when a worker manually unlocks, several steps are required to ensure that the door is not directly opened during the unlocking process, thereby avoiding accidents.

[0003] However, the existing hall door lock can be directly pushed open after being opened in an emergency. When the worker pushes the hall door with both hands, the hall door can be easily pushed open completely. At this time, the hand loses the support of the hall door, and the worker is easy to lose balance and fall into the elevator shaft. Therefore, improvement is needed. SUMMARY

[0004] The purpose of the present application is to provide a right door lock assembly for elevator to solve the problems raised in the background.

[0005] To solve the above technical problems, the present application provides the following technical scheme: a door lock assembly, which comprises an adjusting assembly connected in the door lock assembly, an outer door assembly fixed at the bottom of the door lock assembly, a connecting assembly fixed at the right side of the door lock assembly, a lifting assembly hingedly connected at the bottom of the connecting assembly, a transmission assembly and a pressing-down assembly connected at the inner side of the outer door assembly, a track assembly fixed at the right side of the transmission assembly, and a limiting assembly sliding in the inner part of the outer door assembly, wherein the limiting assembly and the track assembly are matched; the outer door assembly comprises an outer door, a through groove is arranged on the end face of the outer door, a prompt groove is arranged on the outer side of the outer door at one side of the through groove, and a lock rod is rotatably arranged on the end face of the outer door; the connecting assembly comprises a triangular plate fixed at the right side of the door lock assembly, and a movable groove is arranged at the right side of the triangular plate; the lifting assembly comprises a vertical rod sliding at the inner side of the outer door assembly, a pull rod fixed at the top of the vertical rod and located in the movable groove, a prompt block fixed at the middle part of the vertical rod and located in the through groove, and a force receiving block fixed at the bottom of the vertical rod; the pressing-down assembly comprises a convex block rotatably arranged on the outer wall of the lock rod, a pressing rod fixed at the small end of the convex block and corresponding to the top of the force receiving block, and a coil spring fixed between the convex block and the lock rod; the track assembly comprises a track block fixed at the right side of the transmission assembly, and an inclined groove is arranged on the end face of the track block; and the limiting assembly comprises a baffle sliding on the outer part of the outer door and corresponding to the upper and lower ends of the track block, a rubber pad fixed at the outer side of the baffle, a sliding rod fixed between the two baffles, and the sliding rod sliding in the inclined groove.

[0006] As a preferred embodiment of the ladder right door lock assembly of the present invention, the door lock assembly includes a door lock fixing plate fixed to the top of the outer door, a hook plate unit rotating at the front end of the door lock fixing plate, the right side of the hook plate unit fixed to the left side of the triangular plate, and an active contact unit fixed to the right side of the hook plate unit.

[0007] As a preferred embodiment of the ladder right door lock assembly of the present invention, the adjusting assembly includes a spring fixed between the door lock fixing plate and the hook plate unit, a fixing rod fixed to the door lock fixing plate at the spring, and bolts No. 1 and No. 2 screwed to the outer wall of the fixing rod corresponding to the bottom of the hook plate unit.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-9This invention provides a technical solution that, in an emergency, when the hall door is opened, it will not be fully opened, but only a gap will be left for workers to observe the situation inside the elevator shaft. Furthermore, when the hall door latch is opened, the opening status of the latch can be known from the outside, improving the safety of workers unlocking and entering the elevator shaft. An elevator right door lock assembly includes a door lock assembly 100, which includes an adjusting assembly 200 connected within the door lock assembly 100, an outer door assembly 300 fixed to the bottom of the door lock assembly 100, a connecting assembly 400 fixed to the right side of the door lock assembly 100, a lifting assembly 500 movably connected to the bottom of the connecting assembly 400, a transmission assembly 600 and a pressing assembly 700 connected to the inner side of the outer door assembly 300, and a track assembly 8 fixed to the right side of the transmission assembly 600. The limiting component 900, which slides inside the outer door assembly 300, is adapted to the track assembly 800. By using a triangular key to open the lock on the outer door assembly 300, the lock on the outer door assembly 300 will drive the transmission assembly 600, the track assembly 800, and the limiting component 900, causing the limiting component 900 to move outward from the outer door assembly 300. At the same time, the lock on the outer door assembly 300 will drive the pressing assembly 700 to press down the lifting assembly 500 and the connecting assembly 400, causing the connecting assembly 400 to release the lock of the door lock assembly 100. When the outer door assembly 300 is opened, it will be restricted by the limiting component 900 and cannot be fully opened. At this time, the situation inside the elevator shaft can be observed, and the opening and closing status of the door lock assembly 100 can be observed through the lifting assembly 500.

[0032] Specifically, such as Figure 2 , 3 In the middle, the outer door assembly 300 includes an outer door 301. The end face of the outer door 301 is provided with a through groove 302. The outer side of the outer door 301 is provided with a prompt groove 303 on one side of the through groove 302. The prompt groove 303 has two colors with text prompts. The upper part prompts locking and the lower part prompts unlocking. The locking rod 304 rotates on the end face of the outer door 301 and can be opened with a triangular key.

[0033] Furthermore, such as Figure 5 , 6 In the middle, the connecting component 400 includes a triangular plate 401 fixed to the right side of the door lock component 100, and the right side of the triangular plate 401 is provided with a movable groove 402.

[0034] Furthermore, such as Figure 6In the middle, the lifting component 500 includes a vertical rod 501 that slides inside the outer door component 300, a pull rod 502 fixed to the top of the vertical rod 501 in the movable groove 402, a prompting block 503 fixed to the middle of the vertical rod 501 in the through groove 302, when the prompting block 503 moves to the top of the through groove 302, a lock prompt corresponding to the top of the prompting groove 303 is displayed, when the prompting block 503 moves to the bottom of the through groove 302, an unlock prompt corresponding to the bottom of the prompting groove 303 is displayed, and a force-bearing block 504 fixed to the bottom of the vertical rod 501.

[0035] Furthermore, such as Figure 9 In the middle, the pressing component 700 includes a protrusion 701 that rotates on the outer wall of the locking rod 304, a pressure rod 702 fixed to the small end of the protrusion 701 corresponding to the top of the force-bearing block 504, and a coil spring 703 fixed between the protrusion 701 and the locking rod 304. In use, the bottom of the pressure rod 702 at the small end of the protrusion 701 is a certain distance away from the force-bearing block 504, so the protrusion 701 can only squeeze the force-bearing block 504 through the pressure rod 702 after rotating a certain distance.

[0036] Furthermore, such as Figure 3 , 8 In the middle, the track assembly 800 includes a track block 801 fixed to the right side of the transmission assembly 600, and the end face of the track block 801 is provided with a sloping groove 802; the limiting assembly 900 includes a baffle 901 that slides inside the outer door 301 corresponding to the upper and lower ends of the track block 801, a rubber pad 902 fixed to the outside of the baffle 901, and a slide rod 903 fixed between the two baffles 901. The slide rod 903 slides in the sloping groove 802. In use, by moving the track block 801, the slide rod 903 in the sloping groove 802 will be moved, and the slide rod 903 will move the baffle 901 to the outside of the outer door 301, thus limiting the opening of the outer door 301.

[0037] Furthermore, such as Figure 1 In the middle, the door lock assembly 100 includes a door lock fixing plate 101 fixed to the top of the outer door 301, a hook plate unit 102 rotatably rotating at the front end of the door lock fixing plate 101, the right side of the hook plate unit 102 fixed to the left side of the triangular plate 401, and an active contact unit 103 fixed to the right side of the hook plate unit 102.

[0038] Furthermore, such as Figure 2 In the middle, the adjustment component 200 includes a spring 201 fixed between the door lock fixing plate 101 and the hook plate unit 102, a fixing rod 202 fixed to the door lock fixing plate 101 at the spring 201, and a first bolt 203 and a second bolt 204 screwed to the outer wall of the fixing rod 202 corresponding to the bottom of the hook plate unit 102.

[0039] Furthermore, such as Figure 7In the transmission assembly 600, there is a gear 601 fixed to the inner side of the corresponding protrusion 701 on the outer wall of the locking rod 304, a toothed plate 602 meshing with the bottom of the gear 601, the toothed plate 602 sliding inside the outer door 301, and the right side of the toothed plate 602 fixed to the left side of the track block 801.

[0040] In emergency situations, the locking lever 304 is turned using a triangular key. This causes the locking lever 304 to move the gear 601, gear plate 602, and track block 801 to the right. The track block 801 then moves the slide rod 903 within the inclined groove 802. The slide rod 903 moves the baffle 901 outward from the outer door 301, thus limiting the opening of the outer door 301 to a partial extent, allowing workers to observe the elevator shaft. Simultaneously, the locking lever 304 activates the coil spring 703 and the protrusion 70... 1. The pressure rod 702 rotates. After the locking rod rotates a certain distance, the pressure rod 702 will press down on the force block 504. During this process, the coil spring 703 will continuously contract until the pressure rod 702 can press down on the force block 504. This allows the limit component 900 to be triggered first. When the force block 504 descends, it can drive the vertical rod 501, the pull rod 502, and the indicator block 503 to move downwards. The pull rod 502 will move downwards within the movable groove 402, so the pull rod 502 will drive the triangular plate 401 to move downwards. The triangular plate 401 will drive the hook plate unit 10. 2. Rotation unlocks the hook plate unit 102, and the indicator block 503 moves to the bottom of the through slot 302, corresponding to the unlocked state of the bottom of the indicator slot 303. At this time, the worker can open the outer door 301 to observe the situation inside the elevator shaft. The outer door 301 is restricted by the baffle 901, so the outer door 301 will not be fully opened, and the rubber pad 902 will prevent the baffle 901 from hitting the wall. After observation, the above steps can be reset by twisting the locking rod 304. The locking rod 304 mainly drives the gear 601, tooth plate 602, and rail. When the track block 801 moves to the left, the slide bar 903 is located in the inclined groove 802 of the track block 801, so the slide bar 903 will drive the baffle 901 to reset. At this time, the outer door 301 can be opened. At the same time, the locking bar 304 will drive the coil spring 703, the protrusion 701, and the pressure bar 702 to reset, so the hook plate unit 102 will reset. The hook plate unit 102 will drive the triangular plate 401, the pull rod 502, the vertical rod 501, the indicator block 503, and the force block 504 to reset. The above operation can be repeated for the next use.

[0041] In summary, this system ensures that in an emergency, the hall door will not be fully opened when it is opened, leaving only a gap for workers to observe the situation inside the elevator shaft. Furthermore, the status of the door latch can be observed from the outside when it is being opened, thus improving the safety of workers when unlocking and entering the elevator shaft.
