Description

Technical Field

[0001] This invention relates to the field of elevator accessory technology, specifically to a detachable remote unlocking signal device for a villa elevator. Background Technology

[0002] With the improvement of economic level and the diversification of residential building forms, the installation of private elevators in villa residences is becoming increasingly common. Unlike centralized elevators in public buildings, villa elevators are usually installed inside private residences, and their cars run in a shaft exclusively for the residents. The daily use and management of the elevator are the responsibility of the residents themselves.

[0003] In the actual use of villa elevators, when passengers are trapped inside the car and trigger the one-button emergency call, rescuers often need to enter the building before they can reach the elevator to carry out the rescue. However, detached villas usually have main door locks, making it difficult for external rescuers to enter without assistance from people inside, thus delaying the rescue opportunity. To address this, the industry has proposed a solution that links the elevator's remote unlocking signal transmitter with the house's main door lock, allowing trapped individuals to remotely open the door after sending a signal from the elevator. Currently, the signal transmitters used to achieve this function are mostly fixedly installed in the car, with a relatively fixed installation structure that is inconvenient for daily inspection, replacement, or temporary disassembly and maintenance. At the same time, if conventional clips or screws are used for connection within the limited space of the car, it is difficult to balance ease of disassembly and assembly with connection reliability, which can easily lead to accidental loosening or inconvenience in operation, affecting the stable use and maintenance efficiency of this emergency unlocking function.

[0004] Therefore, a detachable remote unlocking signal device for villa elevators is proposed to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a detachable remote unlocking signal device for villa elevators, in order to solve the problem mentioned in the background art that external rescue is hindered by the door lock when people are trapped in villa elevators. Although the existing fixed signal transmitter device in the car can unlock remotely, the installation structure is not convenient for disassembly and maintenance, and the conventional connection method is difficult to balance convenience and reliability.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a detachable remote unlocking signal device for a villa elevator, comprising a car, wherein a remote signal transmitter is detachably installed on the car via a self-locking mechanism; The self-locking mechanism includes a mounting base fixed to the car, a locking pin passing through the mounting base, and a connecting base connected to a remote signal transmitter. The mounting base has a locking groove, which includes a vertical hollow section and a rotating receiving section connected to the vertical hollow section. The cross-sectional shape of the vertical hollow section and the cross-sectional shape of the snap-fit ​​block are both rectangular. The rotating receiving section is an inner cavity located on both sides of the vertical hollow section. The cross-sectional dimension of the rotating receiving section in the plane perpendicular to the insertion direction of the snap-fit ​​block is larger than the cross-sectional dimension of the vertical hollow section. The inner end of the locking pin extends into the rotating receiving section and is opposite to the side wall of the rotated snap-fit ​​block.

[0007] Preferably, a guide limiting sleeve is fixedly connected to one side of the mounting base, the locking pin passes through the guide limiting sleeve, a return spring is sleeved on the outside of the locking pin, a limiting flange is provided on the locking pin, the two ends of the return spring abut against the limiting flange and the guide limiting sleeve respectively, and the limiting flange is integrally formed on the outside of one end of the locking pin.

[0008] Preferably, the axis of the locking pin is perpendicular to the insertion direction of the locking block.

[0009] Preferably, the rotating accommodating section and the vertically hollowed-out section are arranged in a cross shape on the horizontal projection plane.

[0010] Preferably, after the locking block is rotated by °, a pin hole is opened on the side facing the locking pin. The inner end of the locking pin is inserted into the pin hole under the elastic force of the return spring. The inner end of the locking pin is provided with a bevel or an arc-shaped guide surface.

[0011] Preferably, the top end of the snap-fit ​​block is fixedly connected to the connector.

[0012] Preferably, the outer end of the locking pin is fixedly connected to an annular pull ring structure.

[0013] Preferably, the remote signal transmitter is located above the display panel in the car.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: This detachable remote unlocking signal device for villa elevators detachably installs the remote signal transmitter onto the car through a self-locking mechanism. Utilizing the rotational engagement of the locking groove and the snap-fit ​​block, as well as the elastic limiting of the locking pin, it achieves convenient assembly and disassembly, reliable connection, and easy maintenance. The specific details are as follows: Firstly, by detachably installing the remote signal transmitter onto the car via a self-locking mechanism, the signal transmitter can be easily and quickly disassembled and assembled during routine inspections, replacements, or temporary maintenance without the need for special tools or damage to the original installation structure, thereby improving the convenience and efficiency of maintenance operations. At the same time, the self-locking mechanism, through the cooperation of the mounting base, locking pin, and connecting seat, can form a stable locking relationship after the transmitter is installed in place, which helps to reduce the risk of the transmitter becoming loose due to car vibration or misoperation, thus balancing ease of disassembly and assembly with connection reliability.

[0015] Secondly, the locking groove in the self-locking mechanism is designed with a vertical hollow section connected to a rotating receiving section. After the snap-fit ​​block is inserted, it can be rotated into the receiving section, and the locking pin limits its side wall. This provides clear operational guidance and feedback during installation, facilitating quick positioning and locking within the limited space of the car. The locking pin, under the action of the return spring, can hold the snap-fit ​​block after rotation, further improving the stability of the locking state. At the same time, the limit can be released by operating the locking pin, providing convenient conditions for subsequent disassembly. This helps to ensure the stability and maintainability of the emergency unlocking function in long-term use. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-6This invention provides a technical solution: a detachable remote unlocking signal device for villa elevators. The device is integrally mounted on the elevator car 1, and the remote signal transmitter 3 is detachably installed and fixed mainly through a self-locking mechanism 2. While ensuring the stability of the overall connection structure of the equipment, this invention enables rapid disassembly and assembly of the remote signal transmitter 3 for routine maintenance, effectively improving the technical drawbacks of existing similar signal transmitters, such as inconvenient maintenance of fixed installation structures and easy loosening of conventional connection structures.

[0020] This device mainly consists of a car 1 and a remote signal transmitter 3. The remote signal transmitter 3 is detachably mounted to the side wall of the car 1 via a self-locking mechanism 2. In this embodiment, the remote signal transmitter 3 is positioned above the display panel of the car 1. This layout avoids the passenger activity area inside the car 1, reduces interference from personnel touching the device, and prevents equipment and signal obstruction, ensuring stable transmission of the remote unlocking signal.

[0021] The self-locking mechanism 2 is the core structure for achieving detachable assembly in this invention. It mainly includes a mounting base 201 fixedly mounted on the side wall of the car 1, a locking pin 203 transversely passing through the mounting base 201, and a connecting seat 208 fixedly connected to the remote signal transmitter 3. A snap-fit ​​block 207 is fixedly provided at the bottom of the connecting seat 208. The snap-fit ​​block 207 and the connecting seat 208 are connected by integral molding, welding, or bolt fastening to ensure the integrity and structural strength of the connection between the two and avoid loosening during assembly and use.

[0022] The mounting base 201 has a locking groove 206 inside for the insertion and positioning of the snap-fit ​​block 207. The locking groove 206 consists of interconnected vertical hollow sections and rotating receiving sections, which are arranged in a cross shape on the horizontal projection plane. Both the vertical hollow sections and the snap-fit ​​block 207 have rectangular cross-sections. The rectangular structure can accurately guide and limit the vertical insertion movement of the snap-fit ​​block 207, restricting radial offset during the insertion process and improving assembly alignment accuracy. The rotating receiving sections are symmetrically arranged on both sides of the vertical hollow sections. The cross-sectional dimension of the rotating receiving sections in the plane perpendicular to the insertion direction of the snap-fit ​​block 207 is larger than that of the vertical hollow sections. This structure provides sufficient space for the rotational movement of the snap-fit ​​block 207 after insertion, allowing the snap-fit ​​block 207 to complete angular rotation within the rotating receiving sections after vertical insertion, achieving initial positioning.

[0023] A guide limiting sleeve 202 is fixedly connected to the outer wall of the mounting base 201. Preferably, the guide limiting sleeve 202 is integrally formed with the mounting base 201, which can effectively improve the overall structural strength, reduce assembly gaps, and improve the structural fit accuracy. A locking pin 203 is horizontally inserted into the guide limiting sleeve 202, and the axis of the locking pin 203 is perpendicular to the vertical insertion direction of the locking block 207. This spatial fit structure allows the locking force of the locking pin 203 to act perpendicularly on the side wall of the rotated locking block 207, effectively improving the stability and reliability of locking and limiting.

[0024] A return spring 205 is sleeved on the outer side of the locking pin 203, and a ring-shaped limiting flange 204 is integrally formed on the outer side of the locking pin 203. The two ends of the return spring 205 abut against the inner end face of the limiting flange 204 and the outer end face of the guide limiting sleeve 202, respectively. In a natural state without external pulling, the return spring 205 remains compressed and elastic, and can push the locking pin 203 towards the mounting base 201 using its own elastic driving force, thus achieving automatic reset and locking of the locking pin 203. A ring-shaped pull ring structure is provided at the outer end of the locking pin 203, allowing operators to manually pull the locking pin 203 to quickly release the locking limit and simplify the disassembly and assembly process.

[0025] When the locking block 207 is vertically inserted into the rotating receiving section and rotated 90°, a pin hole matching the inner end of the locking pin 203 is formed on the side wall of the locking block 207 facing the locking pin 203. The inner end of the locking pin 203 is provided with a beveled or arc-shaped guide surface. This structure can retract the locking pin 203 during the rotation and alignment of the locking block 207, avoiding structural jamming and ensuring smooth assembly and alignment. After the locking block 207 is rotated into place, the inner end of the locking pin 203 can automatically embed into the pin hole under the elastic action of the return spring 205, forming a double limit on the locking block 207 in the axial and circumferential directions, locking the relative position of the locking block 207 inside the locking groove 206. This limiting structure can effectively offset the risk of loosening caused by the vibration of the car 1 during operation and slight accidental contact, ensuring the structural stability of the remote signal transmitter 3 for long-term use.

[0026] Working principle: When assembling the equipment, the operator aligns the snap-fit ​​block 207 at the bottom of the remote signal transmitter 3 with the vertical cutout section of the mounting base 201 and inserts it vertically. After the snap-fit ​​block 207 is fully inserted into the rotating receiving section, the operator rotates the remote signal transmitter 3, causing the snap-fit ​​block 207 to rotate synchronously by 90°, so that the pin hole of the snap-fit ​​block 207 is precisely aligned with the locking pin 203. After alignment, the locking pin 203 automatically inserts into the pin hole under the elastic drive of the return spring 205, completing the self-locking assembly. No special disassembly and assembly tools are required throughout the process, which is suitable for the narrow assembly space inside the car 1.

[0027] When disassembling and maintaining the equipment, the operator pulls the annular ring at the outer end of the locking pin 203 outward to compress the return spring 205, causing the inner end of the locking pin 203 to exit the pin hole and release the limiting constraint on the locking block 207; then, the remote signal transmitter 3 is rotated in the opposite direction to align the locking block 207 with the vertical hollow section, and the locking block 207 can be pulled out vertically to complete the disassembly. The operation process is simple and can effectively improve the work efficiency of equipment maintenance and replacement.

[0028] 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.
