All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] As recorded in the background art, traditional elevator safety locking mechanisms often rely on manual operations. For example, by installing a latch plate on the elevator guide rail and manually inserting a latch rod into the latch hole by the staff when needed to fix the car to the guide rail, thereby preventing the elevator from moving accidentally. Although the implementation of this method is simple and easy, some drawbacks have also emerged in actual operation. If the latch rod is not completely pulled out of the latch hole and the elevator is accidentally started, it may lead to serious safety accidents, such as the car suddenly moving or falling, seriously threatening the safety of the staff and surrounding people.

[0031] To solve this technical problem, the present utility model provides a steel belt elevator car.

[0032] Specifically, please refer to Figures 1-4 , the steel belt elevator car specifically includes:

A microswitch 204 corresponding to the position of the annular groove 202 is further provided on one side of the support frame 2. The driving rod of the microswitch 204 is located in the annular groove 202.

[0034] In the steel belt elevator car provided by the present utility model, through the provided annular groove 202 and microswitch 204, the driving rod of the microswitch 204 is located in the annular groove 202. When the latch rod main body 201 is inserted, it will touch the driving rod of the microswitch 204, and when the latch rod main body 201 is reset, the touch on the driving rod of the microswitch 204 is released, so that the microswitch 204 can detect the state of the latch rod main body 201, that is, whether it is inserted into the latch hole, which can effectively prevent safety accidents caused by human negligence or misoperation and provide a more solid safety guarantee for the maintenance and repair operations of the elevator.

[0035] To enable those skilled in the art to better understand the solution of the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings.

[0036] It should be noted that, without conflict, the embodiments in the present utility model and the features and technical solutions in the embodiments can be combined with each other.

[0037] It should be noted that like reference numerals and letters indicate like items in the following figures. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] Embodiment 1, please refer to Figures 1-4 , a steel belt elevator car, including a car body 1, a locking part is arranged on the car body 1, the locking part includes a support frame 2 installed on the car body 1, a plug rod body 201 is inserted through the support frame 2, an annular groove 202 is formed on the plug rod body 201, both side walls of the annular groove 202 are inclined, and a microswitch 204 corresponding to the position of the annular groove 202 is further arranged on one side of the support frame 2. The driving rod of the microswitch 204 is located in the annular groove 202. In this application, through the arranged annular groove 202 and microswitch 204, the driving rod of the microswitch 204 is located in the annular groove 202. When the plug rod body 201 is inserted, it will touch the driving rod of the microswitch 204, and when the plug rod body 201 is reset, the touch on the driving rod of the microswitch 204 is released, so that the microswitch 204 can detect the state of the plug rod body 201, that is, whether it is inserted into the socket hole, which can effectively prevent safety accidents caused by human negligence or misoperation, and provide a more solid safety guarantee for the maintenance and repair operations of the elevator.

[0039] Furthermore, as Figure 4 shown, an installation plate 203 is installed on one side of the support frame 2, the microswitch 204 is installed on the installation plate 203, the installation plate 203 is used to support the microswitch 204, and the microswitch 204 is connected to the elevator control system. When the microswitch 204 is touched, the elevator control system does not start the car body 1.

[0040] Furthermore, as Figures 2-4 shown, a horizontal groove 205 and two vertical grooves 206 are formed on the front surface of the support frame 2. The two vertical grooves 206 are respectively located on both sides of the horizontal groove 205, and both vertical grooves 206 communicate with the horizontal groove 205.

[0041] Furthermore, as Figure 3 and Figure 4As shown, a locking rod 207 is slidably connected between the horizontal groove 205 and the vertical groove 206. One end of the locking rod 207 is fixedly connected to the plug rod main body 201. The cooperation between the locking rod 207 and the vertical groove 206 can limit the plug rod main body 201. The cooperation between the locking rod 207 and the vertical groove 206 provides effective limitation for the plug rod main body 201, preventing it from having excessive displacement or coming out during the working process, and increasing the locking stability and safety. This is because during the operation of the elevator, the car will be affected by various forces. If the plug rod main body 201 does not have reliable limitation, it may become loose due to vibration or other external forces, affecting the locking effect.

[0042] Embodiment 2 further optimizes the steel belt elevator car provided in Embodiment 1. Specifically, as Figure 4 shown, the car body 1 includes a car frame 101. A plurality of car enclosures 104 are installed inside the car frame 101. A support frame 2 is connected between the bottoms of the plurality of car enclosures 104. A car top 103 is connected between the tops of the plurality of car enclosures 104. The car frame 101 can support the car bottom 102, the car top 103 and the car enclosures 104.

[0043] Furthermore, as Figure 1 and Figure 5 shown, two stay cable assemblies 3 are provided on both sides of the car frame 101. The stay cable assemblies 3 are used for strengthening the car body 1 and improving the stability of the car frame 101. The stay cable assemblies 3 enhance the structural stability of the car frame 101, reduce the shaking and deformation of the car frame 101 during operation, and improve the comfort and sense of security of passengers.

[0044] Furthermore, as Figure 1 、 Figure 5 and Figure 6 shown, a plurality of vertically arranged first mounting holes 4 are formed on the car frame 101. The stay cable assembly 3 includes a mounting seat 301 connected to the first mounting holes 4 by bolts and a fixing plate 305 fixedly installed at the bottom of the car frame 101. A connecting plate 302 is installed on the mounting seat 301 by bolts. One end of the connecting plate 302 is fixedly connected to a stay cable screw 303. A rotating seat 304 is installed on the fixing plate 305 by bolts. The middle of the rotating seat 304 is inserted and connected with the rotating seat 304. One end of the rotating seat 304 is fixedly connected to the connecting plate 302. A plurality of nuts are threadedly connected to the outer surface of the stay cable screw 303. By providing the plurality of vertically arranged first mounting holes 4, the position of the mounting seat 301 can be adjusted according to the actual situation. The rotating seat 304 is rotatably arranged to meet the inclination angle of the stay cable screw 303 according to the height of the mounting seat 301;

[0045] Multiple vertically arranged first mounting holes 4 enable the installation position of the stay cable assembly 3 to be flexibly adjusted to adapt to different working conditions and requirements, improving the versatility and adaptability of the car body 1. The rotatable design of the rotating seat 304 ensures that the stay cable screw 303 can provide tension at the best angle, further enhancing the stability of the car frame 101. This is because different elevator installation environments and usage conditions may require different stay cable angles and positions, and this flexible design can meet diverse requirements.

[0046] Embodiment 3 further optimizes the steel belt elevator car provided in Embodiment 2. Specifically, as Figure 1 and Figure 7 shown, a detection part is also installed on the car frame 101. The detection part is used to realize the leveling detection when the car body 1 is running, ensuring that the car body 1 accurately stops at each floor during operation, improving the accuracy of elevator operation and the usage experience of passengers. Because inaccurate leveling may cause dangerous situations such as passengers tripping when entering and leaving the elevator, accurate leveling detection can avoid such situations.

[0047] Furthermore, as Figure 1 and Figure 7 shown, the detection part includes several second mounting holes 5 opened on the car frame 101. The car frame 101 is installed with a mounting frame 501 through bolts and two of the second mounting holes 5. At least two optoelectronic switch bodies 502 are installed on the mounting frame 501. Using at least two optoelectronic switch bodies 502 can reduce the detection error. Through the several second mounting holes 5 provided, the several second mounting holes 5 are also vertically arranged, and this setting can adjust the installation height of the mounting frame 501 according to the actual situation.

[0048] Furthermore, as Figure 1 shown, two side guardrails 105 are installed at the top of the car frame 101, and a rear guardrail 106 is installed between the two side guardrails 105. There are gaps between the bottoms of the side guardrails 105 and the rear guardrail 106 and the top of the car top 103. This setting makes the bottoms of the side guardrails 105 and the rear guardrail 106 suspended. On the one hand, it can reduce the material used for the side guardrails 105 and the rear guardrail 106 to reduce the overall weight. On the other hand, it can reduce the situation where the side guardrails 105 and the rear guardrail 106 block the operation of maintenance personnel during elevator maintenance.

[0049] In the present utility model, unless otherwise clearly defined and limited, terms such as "installation", "connection", "linkage", "fixation" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral body; it may be a mechanical connection, an electrical connection, or communication with each other; it may be directly connected, or indirectly connected through an intermediate medium, and may be the internal communication of two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0050] Obviously, the embodiments described above are only a part of the embodiments of the present utility model, rather than all embodiments. The accompanying drawings show the preferred embodiments of the present utility model, but do not limit the patent scope of the present utility model. The present utility model can be implemented in many different forms.
