Description

Technical Field

[0001] This utility model relates to the field of elevator lighting technology, specifically to a controllable elevator arrival light. Background Technology

[0002] Elevators are closely related to our lives. Elevator arrival lights are installed on the outside of the elevator. By turning on the light, they remind passengers that the elevator is about to arrive at the station and whether the elevator is going up or down, giving passengers a clear and intuitive visual experience.

[0003] Publication number CN219636666U discloses a novel elevator arrival light, relating to the field of elevator lighting technology. It includes a first outer shell, with a second outer shell symmetrically bonded to both sides of the first outer shell, and a third outer shell bonded to one side of the second outer shell. All three outer shells are made of plastic, and grooves are formed along their central axes. A mounting groove is symmetrically formed on the top of the first outer shell, and a triangular LED light panel is embedded within the mounting groove. This design is simple, elegant, and suitable for various locations. While this design aims to improve the aesthetics of arrival lights by creating a layered rectangular shape for some elevators, it still has the following problems in practical use:

[0004] Because the above-mentioned device uses a two-way threaded rod for fixing, it requires a long-distance rotation using a tool during assembly and disassembly. Since the tool is a custom-made structure, it cannot be assisted by electric equipment for long-term rotation, and manual rotation is time-consuming. During installation, the clamping plate needs to have sufficient compressive force so that the serrated groove can fully play its function of increasing friction. Therefore, rotation is quite laborious. In short, this installation structure is time-consuming and laborious to use.

[0005] An elevator controllable arrival light is proposed to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide an elevator controllable arrival light to solve the problem mentioned in the background art. The device uses a bidirectional threaded rod for fixing, which requires long-distance rotation with tools during disassembly and assembly. Because the tool is a custom structure, it cannot be assisted by electric equipment for long-term rotation, and manual rotation is time-consuming. During installation, the clamping plate needs to have sufficient compressive force so that the serrated groove can fully play its function of increasing friction. Therefore, rotation is laborious. In short, this installation structure is time-consuming and laborious to use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an elevator controllable arrival light, including a mounting plate, the mounting plate including a station light base, the station light base having a mounting plate fitted on it, and the top surface of the mounting plate having an indicator light;

[0008] A docking assembly is provided on the outer side of the station light base. The docking assembly includes mounting strips symmetrically fixed to the outer side of the station light base. A pair of linkage gears are provided inside the mounting strips. A support shaft is fixedly connected to the middle of one linkage gear, and a connecting pipe is fixedly connected to the middle of the other linkage gear. A pair of limiting strips are fixedly connected to the top inner wall of the connecting pipe. An installation cylinder is provided inside the connecting pipe. A lifting column is slidably connected to the top of the installation cylinder. Limiting grooves are symmetrically opened on both sides of the lifting column. A spring is fixedly installed inside the installation cylinder.

[0009] The mounting strip has a clearance hole on its top surface, a control post is movably connected inside the clearance hole, control slots are symmetrically provided on both sides of the control post, and a knob is fixedly connected to one end of the control post.

[0010] The mounting strip has a pair of locating pins slidably connected to the side away from the station light base. One end of the locating pin is fixedly connected to a rack inside the mounting strip, and the other end of the locating pin is inserted into a locking hole opened inside the mounting plate.

[0011] Preferably, the support shaft and the connecting pipe are rotatably connected to the inner bottom surface of the mounting strip, the connecting pipe is rotatably connected to the inner bottom surface of the mounting strip through a bearing, the bottom end of the spring is fixedly connected to the inner bottom surface of the mounting cylinder, and the top end of the spring is fixedly connected to the bottom of the lifting column.

[0012] Preferably, the limiting groove is slidably connected to the limiting strip.

[0013] Preferably, the control groove is slidably connected to the limiting strip.

[0014] Preferably, the two connecting gears are meshed with each other, and each connecting gear is connected to one of the racks.

[0016] Preferably, the top surface of the mounting plate is provided with a protective component, the protective component including a mounting ring fixed to the edge of the mounting plate, the mounting ring having a threaded groove, and an acrylic cover being threadedly connected to the threaded groove.

[0017] Compared with the prior art, the beneficial effects of this utility model are: this elevator controllable arrival light, through gear linkage and sliding control mechanism, achieves one-button 180-degree rotation for quick installation and spring self-locking function, which significantly improves installation efficiency and ensures connection reliability. The specific details are as follows:

[0018] 1. Through innovative gear linkage mechanism and sliding control structure design, the operator only needs to rotate the knob 180 degrees to complete the entire installation process, greatly simplifying the traditional multi-step installation procedure. When the control column is pressed down, it automatically releases the limit switch, driving the linkage gear to rotate synchronously, and pushing the positioning pin into the locking hole precisely through the rack; when the control column is withdrawn, the spring drives the lifting column to reset, causing the limit groove and limit strip to re-engage, forming a mechanical self-lock, effectively preventing loosening caused by vibration during elevator operation. This "one-button rotation installation + automatic locking" design not only significantly improves installation efficiency, but also ensures the reliability of the connection through a double locking mechanism, while the precise matching of the gear transmission ensures that the extension length of the positioning pin remains consistent;

[0019] 2. The use of threaded acrylic covers instead of traditional adhesive fixing methods allows maintenance personnel to quickly replace the covers by rotating them individually when they become scratched, yellowed, or damaged. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-6 The present invention provides a technical solution: an elevator controllable arrival light, including a mounting plate 1, the mounting plate 1 including a station light base 101, the station light base 101 being fitted with a mounting piece 102, and an indicator light 103 being provided on the top surface of the mounting piece 102; the structure adopts a modular design, which facilitates quick disassembly and maintenance;

[0029] A docking assembly 2 is provided on the outer side of the station light base 101. The docking assembly 2 includes mounting strips 201 symmetrically fixed to the outer side of the station light base 101. A pair of linkage gears 202 are provided inside the mounting strips 201. A support shaft 203 is fixedly connected to the middle of one linkage gear 202, and a connecting pipe 204 is fixedly connected to the middle of the other linkage gear 202. A pair of limiting strips 205 are fixedly connected to the top inner wall of the connecting pipe 204. An installation cylinder 206 is provided inside the connecting pipe 204. A lifting column 207 is slidably connected to the top of the installation cylinder 206. Limiting grooves 208 are symmetrically opened on both sides of the lifting column 207. A spring 212 is fixedly installed inside the installation cylinder 206. This design achieves one-click installation through a gear transmission mechanism. During operation, only a 180-degree rotation is needed to complete the positioning, which greatly improves the installation efficiency. The rotation stroke of the linkage gear 202 is 180 degrees.

[0030] The top surface of the mounting strip 201 has a clearance hole, and a control column 209 is movably connected inside the clearance hole. Control slots 210 are symmetrically opened on both sides of the control column 209, and a knob 211 is fixedly connected to one end of the control column 209. After the staff takes the control column 209 away, others cannot operate this device at will.

[0031] Among them, a pair of positioning pins 214 are slidably connected to the side of the mounting strip 201 away from the station light base 101. One end of the positioning pin 214 located inside the mounting strip 201 is fixedly connected to a rack 213, and the other end of the positioning pin 214 is inserted into a locking hole 215 opened inside the mounting plate 1.

[0032] The support shaft 203 and the connecting pipe 204 are rotatably connected to the inner bottom surface of the mounting strip 201. The connecting pipe 204 is rotatably connected to the inner bottom surface of the mounting strip 201 through a bearing. The bottom end of the spring 212 is fixedly connected to the inner bottom surface of the mounting cylinder 206, and the top end of the spring 212 is fixedly connected to the bottom of the lifting column 207.

[0033] The limiting groove 208 and the limiting strip 205 are slidably connected, with the clearance controlled at 0.1-0.2mm to ensure smooth movement while preventing wobbling. This design allows for automatic reset and locking after the control column 209 is removed, preventing loosening caused by elevator vibration.

[0034] The control groove 210 is slidably connected to the limit bar 205. The length of the control groove 210 is 3-5mm longer than that of the limit bar 205, providing buffer space for movement. Two connecting gears 202 mesh with each other and are connected by cooperating with a rack 213.

[0035] The length of the control groove 210 is greater than that of the limit strip 205, and the control post 209 and the clearance hole are fitted with a clearance fit. This structure can automatically lock after installation without the need for additional tightening.

[0036] A protective component 3 is provided on the top surface of the mounting plate 102. The protective component 3 includes a mounting ring fixed to the edge of the mounting plate 102. A threaded groove 301 is provided inside the mounting ring, and an acrylic cover 302 is threadedly connected to the threaded groove 301. The acrylic cover 302 has high light transmittance and can be quickly replaced through the threaded connection.

[0037] Working principle: Before using this type of elevator controllable arrival light, it is necessary to check the overall condition of the device to ensure it can work normally. Figure 1 - Figure 6 As shown, firstly, the light stand base 101 and the mounting strip 201 are embedded together into the mounting plate 1. Then, by holding the knob 211, the control column 209 is inserted into the mounting strip 201 through the clearance hole. At this time, the control column 209 will be inserted into the connecting tube 204. During this process, the control column 209 will push the lifting column 207 into the mounting cylinder 206, so that the limiting groove 208 is disengaged from the sliding of the limiting strip 205. At the same time, the limiting strip 205 slides into the control groove 210. At this time, the knob 211 is rotated, the control column 209 rotates and drives the connecting tube 204 to rotate through the control groove 210 and the limiting strip 205. When the connecting tube 204 rotates, it will drive a connecting gear 202 to rotate. Under the meshing of the two connecting gears 202, the two connecting gears 202 synchronously drive the rack 213 to move. When the rack 213 moves, it will drive the positioning pin 214 to move together. The positioning pin 214 extends out of the mounting strip 201 and is inserted into the locking hole 215.

[0038] The installation strip 201 connects to the station light holder 101 for quick installation. During the rotation, the connecting gear 202 only needs to rotate 180 degrees to complete the operation, making it more convenient for a single person to operate quickly. After the operation is completed, the control column 209 is pulled out of the clearance groove, which causes the spring force of the spring 212 to push the lifting column 207 to reset. During the upward movement of the control column 209, the lifting column 207 automatically allows the limit groove 208 to slide and engage with the limit strip 205. The design that the limit groove 208 and the installation cylinder 206 cannot rotate relative to each other makes it impossible for the limit strip 205 and the connecting pipe 204 to rotate at this time, which finally causes the connecting gear 202 to be unable to rotate, thus completing the automatic locking.

[0039] The acrylic cover 302 can be replaced by rotating it, avoiding the situation where the traditionally bonded acrylic cover 302 is difficult to replace due to wear or damage.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
