[0001] This utility model relates to the field of elevator technology, and more specifically, to a home elevator. Background Technology
[0002] With the acceleration of urbanization and the improvement of residents' living standards, home elevators have gradually become an important facility for improving the quality of life in modern residences. During the installation, maintenance and routine inspection of elevators, ensuring the safety of workers is of paramount importance. Therefore, guardrails need to be installed on the top of the elevator car to prevent workers from accidentally falling from the top of the car. This regulation is of great significance for protecting the life safety of elevator maintenance personnel.
[0003] However, in practical applications, especially in residential shafts with low ceiling heights, installing traditional fixed-height guardrails presents challenges. Due to space constraints, these shafts often cannot meet the minimum height requirements for guardrail installation, thus affecting the safety and practicality of the elevator. Furthermore, fixed guardrail designs may limit the utilization of space above the car. Therefore, we propose an improvement: a home elevator. Summary of the Invention

[0027] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 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 should fall within the protection scope of the present invention.
[0028] As described in the background section, in practical applications, especially in residential shafts with low ceiling heights, installing traditional fixed-height guardrails presents challenges. Due to space constraints, these shafts often cannot meet the minimum height requirements for guardrail installation, thus affecting the safety and practicality of the elevator. In addition, fixed guardrail designs may also limit the utilization of space on the top of the car.
[0029] To solve this technical problem, this utility model provides a home elevator.
[0030] For details, please refer to Figures 1-2 Home elevators specifically include:
[0031] An elevator car 1 has a protective railing body 2 fitted on the top of its outer surface. A limit structure 3 is provided between the protective railing body 2 and the elevator car 1. The limit structure 3 is used to fix the position of the protective railing body 2. The protective railing body 2 is liftable.
[0032] The home elevator provided by this utility model features a protective railing body 2 that can be raised and lowered to flexibly adjust according to the actual top floor height of the shaft. This allows the protective railing body 2 to be raised during elevator maintenance or repair, effectively reducing the risk of workers falling from the top of the car and ensuring operational safety to meet the needs of low-ceiling shafts. In non-operational states, the protective railing can be lowered to a lower position, reducing the occupation of the top space of the elevator car 1 and meeting the needs of low-ceiling shafts.
[0033] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0034] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0035] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0036] Example 1, please refer to Figures 1-2 A home elevator includes an elevator car 1. A guardrail body 2 is fitted on the top of the outer surface of the elevator car 1. A limit structure 3 is provided between the guardrail body 2 and the elevator car 1. The limit structure 3 is used to fix the position of the guardrail body 2. The guardrail body 2 is liftable.
[0037] Furthermore, the main body 2 of the guardrail is raised during maintenance to provide protection for maintenance personnel, and lowered during elevator car 1 operation to reduce the space at the top of elevator car 1. That is, during elevator maintenance or repair, the main body 2 of the guardrail can be raised to effectively reduce the number of workers falling from the top of the car, ensuring work safety and meeting the usage requirements of the low top floor shaft. In non-operational state, the guardrail can be lowered to a lower position, reducing the occupation of the top space of elevator car 1 and meeting the usage requirements of the low top floor.
[0038] Example 2 further optimizes the home elevator provided in Example 1, specifically, as follows: Figure 1 As shown, a number of first blocks 201 are fixedly connected to the top of the inner wall of the guardrail body 2. The first blocks 201 are used to limit the movement of the guardrail body 2 after it descends. That is, after the guardrail body 2 descends, the first blocks 201 contact the top of the elevator car 1. The first blocks 201 can be supported and limited by the cooperation between the first blocks 201 and the elevator car 1.
[0039] Furthermore, such as Figure 1As shown, a notch is provided inside the main body 2 of the guardrail, and a second stop 202 corresponding to the notch is provided on the side of the elevator car 1. The second stop 202 is used to limit the movement of the main body 2 of the guardrail when it rises. That is, during the process of lifting the main body 2 of the guardrail upward, the limit of the main body 2 of the guardrail by the second stop 202 can help the staff to confirm whether it has been lifted into place.
[0040] Furthermore, such as Figure 1 and Figure 3 As shown, handles 203 are fixedly installed on both sides of the top of the guardrail body 2. The handles 203 make it easy for staff to lift the guardrail body 2.
[0041] Example 3 further optimizes the home elevator provided in Example 1 or 2. Specifically, the limiting structure 3 includes two limiting members, both of which are set between the elevator car 1 and the guardrail body 2. The limiting members are used to fix the guardrail body 2.
[0042] Furthermore, such as Figure 2 As shown, the limiting component includes two limiting holes 301, which are formed on the side wall of the guardrail body 2.
[0043] Furthermore, such as Figure 1 and Figure 3 As shown, the limiting component also includes a mounting plate 302 installed on the top of the elevator car 1. Two support seats 303 are fixedly installed on the top of the mounting plate 302. A limiting rod 304 is inserted between the two support seats 303. One end of the limiting rod 304 is inserted into the inner wall of one of the limiting holes 301. By inserting the limiting rod 304 into the limiting hole 301, the support and limiting of the guardrail body 2 can be achieved.
[0044] Furthermore, such as Figure 3 and Figure 4 As shown, a stop bar 306 is fixedly connected to the limiting rod 304. The stop bar 306 is located between two support seats 303. A spring 305 is also sleeved on the outer surface of the limiting rod 304. The spring 305 is located between the stop bar 306 and one of the support seats 303. The force of the spring 305 can improve the stability of the insertion of the limiting rod 304 and the limiting hole 301.
[0045] Furthermore, as shown in the diagram, malignant nuclei Figure 4As shown, a baffle 307 is fixedly installed on the top of the mounting plate 302. The baffle 307 is located between two support seats 303. After pulling the limiting rod 304 to separate the limiting rod 304 from the limiting hole 301, rotating the limiting rod 304 causes the stop rod 306 to be stopped by the baffle 307, thereby limiting the limiting rod 304 to facilitate the operation of the guardrail body 2. The end of the limiting rod 304 away from the limiting hole 301 is bent. This setting makes it easy to use your foot to pry the bent part of the limiting rod 304 during the process of lifting the guardrail body 2, so as to realize the rotation of the limiting rod 304.
[0046] The home elevator provided by this utility model is used as follows:
[0047] During maintenance, workers enter the top of the elevator car 1 and pull the limit rod 304 to separate it from the limit hole 301. Rotating the limit rod 304 causes the stop bar 306 to be stopped by the baffle 307, thus limiting the limit rod 304. Pulling the handle 203 upwards raises the guardrail body 2. When the guardrail body 2 reaches its highest point, rotating the limit rod 304 separates the stop bar 306 from the baffle 307. At this point, the limit rod 304, under the force of the spring 305, inserts into the corresponding limit hole 301, thus limiting the guardrail body 2. Figure 4 As shown; after maintenance is completed, pull the limiting rod 304 to separate the limiting rod 304 from the limiting hole 301. Rotate the limiting rod 304 so that the stop rod 306 is stopped by the baffle 307, thereby limiting the limiting rod 304. Push the guardrail body 2 down to the lowest position, and rotate the limiting rod 304 to separate the stop rod 306 from the baffle 307. At this time, the limiting rod 304 is inserted into the corresponding limiting hole 301 under the action of the spring 305 to limit the guardrail body 2, that is, as shown. Figure 1 As shown.
