Description

Technical Field

[0001] The present application relates to the field of elevator safety detection, and in particular to an easy-to-install laser ranging device for elevators. Background Art

[0002] Laser ranging technology, due to its high precision, speed, and non-contact nature, is widely used in elevator installation, maintenance, and operation monitoring. Traditional elevator installation typically requires manual measurement to determine the precise position of various components. However, due to the limited space and poor lighting conditions in elevator shafts, manual measurement accuracy and efficiency are insufficient to meet practical requirements. Furthermore, routine inspection and maintenance of elevators require frequent distance measurements between operating components, but traditional methods are also cumbersome, time-consuming, and subject to significant errors.

[0003] Although the laser ranging devices currently on the market can be used for elevator installation and testing, they generally have the following defects:

[0004] Cumbersome installation: Existing distance measuring devices are usually connected to the elevator shaft or other components via bolts or fixing clamps. The installation process is time-consuming and labor-intensive, especially in scenarios with narrow spaces or where frequent disassembly and assembly are required.

[0005] Insufficient stability: After installation, some devices become loose due to vibration or force, resulting in inaccurate distance measurement results and unable to meet the precise measurement requirements during elevator operation.

[0006] Inconvenient adjustment: During use, the existing devices mostly rely on manual adjustment or simple mechanical structures to adjust the measurement direction, which lacks flexibility and is difficult to adapt to the needs of different angles or complex measurement scenarios.

[0007] In summary, existing elevator laser distance measuring devices have room for improvement in terms of installation convenience, operational stability, operational flexibility, and protection. Therefore, there is an urgent need for a laser distance measuring device that is quick to install, stable and reliable, easy to adjust, and offers good protection. This can improve elevator installation and maintenance efficiency and address the challenges of existing technologies. Summary of the Invention

[0035] Example 1

[0036] like Figure 1-4 As shown, the present application relates to an elevator laser distance measuring device that is easy to install, comprising: a mounting base 1, a laser distance meter 2, an insertion slot 3, a mounting block 4, a spring slot 5, a spring 7, a limiter 8, a movable slot 9 and a handle 10. Specifically:

[0037] The front side of the mounting base 1 has an inwardly defined insertion slot 3, which is movably connected to the mounting block 4. A spring slot 5 is defined within the mounting base 1 below and communicates with the insertion slot 3. A snap-fit ​​slot 6 is defined below the mounting block 4. A spring 7 is located within the spring slot 5, and the upper end of the spring 7 is connected to a stopper 8, which moves within the spring slot 5 and the insertion slot 3. When the mounting block 4 is connected to the insertion slot 3, the stopper 8, under the action of the spring 7, inserts into the snap-fit ​​slot 6 of the mounting block 4, thereby securing the mounting block 4.

[0038] A movable groove 9 is provided on the side wall of the spring groove 5, and a handle 10 for pressing the limiter 8 is connected to the movable groove 9. When the mounting block 4 needs to be installed or removed, the limiter 8 can be disengaged from the clamping groove 6 by pressing the handle 10, thereby achieving quick installation and removal.

[0039] The laser rangefinder 2 is fixed to the mounting block 4 via a U-shaped bracket 11 , which can effectively stabilize the position of the laser rangefinder 2 .

[0040] In the embodiment of the present application, a detachable limiting device is adopted, and the purpose of rapid installation and disassembly is achieved through the cooperation of the limiting member 8 and the snap-in groove 6, thereby achieving a technical effect of taking both convenience and stability into consideration, and further solving the technical problems of the existing elevator laser ranging device being cumbersome to install and not firmly fixed.

[0041] In this embodiment, a guide groove 12 is further defined within the insertion slot 3, and a guide bar 13 is provided on the side of the mounting block 4. When the mounting block 4 is inserted into the insertion slot 3, the guide bar 13 is inserted into the guide groove 12, achieving precise positioning, effectively preventing the mounting block 4 from shifting during installation, and improving installation accuracy and stability.

[0042] In this embodiment, the upper end of the spring 7 is connected to a movable block 14. The outer peripheral sidewall of the movable block 14 engages with the inner wall of the spring groove 5, and the limiting member 8 is fixedly connected to the movable block 14. This structure further enhances the positioning effect of the limiting member 8 through the stable engagement of the movable block 14, thereby improving the fixing strength of the mounting block 4.

[0043] In this embodiment, a handle 10 is connected to the side wall of the movable block 14, with one end of the handle 10 protruding from the movable groove 9. Manually operating the protruding handle 10 conveniently controls the movement of the stopper 8, improving operational convenience. Furthermore, a grip ball 15 with a non-slip texture is provided at the end of the handle 10. This design enhances grip comfort and controllability of the handle 10, effectively preventing misoperation due to slippage.

[0044] In this embodiment, the top and bottom ends of the laser rangefinder 2 are detachably mounted with protective covers 18 by screws. The protective covers 18 can effectively prevent the laser rangefinder 2 from being subjected to external impacts during transportation or use, thereby improving the durability of the device.

[0045] In this embodiment, a mounting plate 19 is provided on the mounting base 1. The mounting base 1 can be fixed to the wall or other supporting structure of the elevator through the mounting plate 19, thereby improving the installation flexibility and adaptability of the entire device.

[0046] Example 2

[0047] In this embodiment, the outside of the laser rangefinder 2 is axially connected to the U-shaped bracket 11 through two rotating columns 16. A motor 17 is provided on the outside of the U-shaped bracket 11, and the output shaft of the motor 17 is connected to one of the rotating columns 16. Driven by the motor 17, the laser rangefinder 2 can achieve angle adjustment to meet the needs of different measurement scenarios.

[0048] The working principle of the device is as follows: the insertion slot 3 on the front side of the mounting base 1 provides preliminary positioning for the mounting block 4, and the guide slot 12 set in the insertion slot 3 and the guide bar 13 on the mounting block 4 further improve the positioning accuracy and prevent displacement during the insertion process; when the mounting block 4 is inserted into the insertion slot 3, the elastic force generated by the spring 7 in the spring slot 5 pushes the limiter 8 into the clamping slot 6 of the mounting block 4, completing the fixation of the mounting block 4; when disassembly is required, by pressing the handle 10, the limiter 8 overcomes the elastic force of the spring 7 and disengages from the clamping slot 6, and the mounting block 4 can be easily removed; the whole process simplifies the traditional bolt fixing method and improves the assembly and maintenance efficiency.

[0049] From the above description, it can be seen that the present application achieves the following technical effects: in the embodiment of the present application, a detachable limiting device is adopted, and the purpose of rapid installation and disassembly is achieved through the cooperation of the limiting member 8 and the snap-in groove 6, thereby achieving a technical effect of taking into account both convenience and stability, and thus solving the technical problems of the existing elevator laser ranging device being cumbersome to install and loosely fixed.

[0050] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
