Description

Technical Field

[0001] This utility model relates to the field of elevator technology, specifically to an elevator door lock bypass device. Background Technology

[0002] During elevator maintenance, maintenance personnel need to short-circuit the door lock circuit to troubleshoot the fault;

[0003] A current elevator door lock bypass device, as described in patent CN209758772U, solves the problem of door lock malfunctions that occur during elevator maintenance and repair, preventing normal elevator operation. Maintenance personnel often short-circuit the door lock circuit to troubleshoot, but frequently forget to remove the original short-circuit wire, leading to safety accidents. The device includes a housing with a hall door bypass short-circuit terminal installed on one side and a bypass closing short-circuit terminal installed in the middle of the inner side. This invention uses a bypass connector and a safety sliding cover to bypass the hall door or car door contacts, improving safety during maintenance. The sliding mechanism allows the safety sliding cover to lock and slide back and forth without requiring manual inspection of whether the mounting plug on the safety sliding cover is aligned with the hall door bypass short-circuit terminal, the bypass closing short-circuit terminal, and the car door bypass short-circuit terminal.

[0004] Regarding the aforementioned technologies, the applicant discovered that an elevator door lock bypass device, when in use, uses a spring to push the positioning buckle to position the sliding device. However, after long-term use, the spring undergoes fatigue deformation, leading to a decrease in positioning force and a risk of positioning failure, thus affecting the safety performance of the equipment. Therefore, we propose an elevator door lock bypass device. Utility Model Content

[0005] The purpose of this utility model is to provide an elevator door lock bypass device that can solve the problem of positioning reliability of the device mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an elevator door lock bypass device, comprising a housing, a hall door bypass short-circuit terminal, a bypass closing short-circuit terminal, and a car door bypass short-circuit terminal.

[0015] By adopting the above technical solution, the position of the box can be accurately observed.

[0016] Preferably, there are three card slots, and the positions of the three card slots and the scale are on the same horizontal plane.

[0017] By adopting the above technical solution, the box can be effectively fixed when it is moved to different positions.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Firstly, by setting up a housing, hall door bypass short-circuit terminal, bypass closing short-circuit terminal, car door bypass short-circuit terminal, bypass plug, and transmission assembly, the transmission assembly drives the gears through a transfer handle.

[0030] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0031] Please see Figures 1-3 The diagram illustrates an elevator door lock bypass device, comprising a housing 1, a hall door bypass short-circuit terminal 101, a bypass closing short-circuit terminal 102, and a car door bypass short-circuit terminal 103. A cover 104 is fixedly installed on the outer wall of the housing 1. A transmission assembly 2 is provided on the top of the housing 1, including a sliding cover 201 slidably connected to the top of the housing 1. A limiting plate 2011 is fixedly installed on one side of the top of the housing 1. The limiting plate 2011 has a T-shaped cross-section and is slidably connected to the top wall of the sliding cover 201. An installation plug is fixedly installed at the middle position of the top of the sliding cover 201. The top of the sliding cover 201 is provided with a bypass plug 105, which is connected to the mounting plug 202. Inside the sliding cover 201, near the mounting plug 202, a handle 203 is rotatably connected. A gear 204 is fixed at the bottom of the handle 203. A toothed plate 205 is fixed on one side of the top of the box 1. The gear 204 meshes with the toothed plate 205. A hemispherical locking block 206 is fixed on the top wall of the sliding cover 201 near the handle 203. The hemispherical locking block 206 is made of elastic plastic. The top of the toothed plate 205 has a slot 2061 for the hemispherical locking block 206 to engage.

[0032] When the elevator is in normal operating mode, the bypass plug 105 is inserted into the bypass closing short-circuit terminal 102, and the hall door bypass short-circuit terminal 101 and car door bypass short-circuit terminal 103 are concealed by the sliding cover 201. When the elevator enters the hall door bypass, the bypass plug 105 is unplugged, and the throttle 203 is turned counterclockwise. Through the transmission of the gear plate 205, the housing 1 is moved to the left under the limit of the limiting plate 2011. During the movement of the gear plate 205, the hemispherical locking block 206 abuts against the surface of the gear plate 205 until the housing 1 is moved to the final position. At this point, the hemispherical locking block 206 automatically engages with the locking slot 2061, increasing the resistance of the throttle 203. Then, the only bypass plug 105 is inserted into the hall door bypass short-circuit terminal 101, bypass closing short-circuit terminal 102, and car door bypass short-circuit terminal 103 through the installation plug 202. When the elevator is in a concealed state and automatically enters emergency electric or maintenance operation mode, when the elevator enters the car door bypass, the bypass plug 105 is pulled out again, and the handle 203 is turned clockwise until the hemispherical block 206 engages with the slot 2061 on the right end of the gear plate 205 again. At this time, the hall door bypass short-circuit terminal 101 and bypass closing short-circuit terminal 102 plugs are in a concealed state and automatically enter the emergency electric or maintenance operation mode. Then, through the drive of the gear 204 by the handle 203 in the transmission component 2, and under the transmission of the gear plate 205, the position of the hall door bypass short-circuit terminal 101, bypass closing short-circuit terminal 102 and car door bypass short-circuit terminal 103 of the box body 1 is quickly adjusted. With the engagement of the hemispherical block 206 and the slot 2061, the precise positioning of the box body 1 at the pre-moving position is achieved, further improving the reliability of the device during use.

[0033] Please see Figure 1 , Figure 2 and Figure 4 In the figure, an indicator component 3 is installed on the outer wall of the box body 1 near the cover 104. The indicator component 3 includes a visual glass 301, which is fixedly installed on one side of the sliding cover 201. Three horizontally equidistant indicator plates 302 are fixed on one side of the outer wall of the box body 1. The outer wall of the indicator plate 302 is fixed with a scale 3021. There are three slots 2061. The three slots 2061 and the scale 3021 are on the same horizontal plane. The outer wall of the visual glass 301 is fixed with a pointer 303 corresponding to the indicator plate 302.

[0034] When the box 1 is driven and moved by the throttle 203 in the transmission assembly 2, the indicator 302 on the outer wall of the box 1 moves synchronously. The real-time distance between the scale 3021 on the indicator 302 and the pointer 303 on the visual glass 301 can be observed through the visual glass 301. When the pointer 303 on the visual glass 301 overlaps with the scale 3021, it means that the movement of the box 1 is complete. Thus, through the cooperation of the indicator 302 and the visual glass 301 in the indicator assembly 3, the movement of the box 1 is displayed intuitively. With the cooperation of the pointer 303 and the scale 3021, the accuracy of the position movement of the box 1 is effectively provided, further improving the safety of the device during use.
