[0020] like Figures 1 to 8As shown, this embodiment discloses a compact villa elevator, comprising a car body 1, a car frame 2, a car guide shoe 3, a car guide rail 4 and a derrick 5, wherein the derrick 5 is upright and fixed on the ground, and the car body 1 is located inside the derrick 5. The rear portion of the car body 1 is provided with an inwardly recessed mounting portion 11, and car guide shoes 3 are installed on both sides of the outside of the car frame 2. The car guide rails 4 slide in conjunction with the car guide shoes 3, and the car guide rails 4 are fixedly installed on the left and right sides of the inside of the derrick 5, and the car guide rails 4 extend in the up and down directions. The outer distance S1 between the car guide rails 4 is ≤ the left and right outer dimensions S2 of the car body 1; an elevator call device 6 is installed on the inner rear side of the car body 1. In this embodiment, the car frame 2 is connected to the rear of the car body 1, and an inwardly recessed mounting portion 11 is provided at the rear of the car body 1, so that the left and right sides of the car frame 2 are embedded in the mounting portion 11, that is, the car frame 2 is installed in a manner of moving backward and retracting, so that the car frame 2 does not protrude and occupy the space on the left and right sides of the well frame 5, so that the space in front of the car body 1 at the mounting portion 11 can be close to the inner wall of the well frame 5, so that the internal space of the car body 1 is larger; at the same time, the car frame 2 is connected to the rear of the car body 1, and there are no obstructing mechanical parts on the front and left and right sides of the car body 1, so the elevator can choose to open the front door, the left door and the right door, and the choice of the door opening direction More, it can be applied to more usage scenarios, and the flexibility of elevator installation is higher; in addition, after the installation position of the car frame 2 is moved backward and retracted, the lateral space on the front side of the car body 1 can be increased. Although the lateral space on the rear side will be reduced, when the elevator opens the door on the front side, the space for users to enter from the front side is larger, which can meet most space usage needs. Therefore, the reduction in the lateral space on the rear side has little impact on the use of the elevator; this embodiment also installs the elevator call device 6 on the rear side of the car, so that after entering the elevator, the passengers naturally walk to the rear side of the car to choose the floor to arrive at, thereby moving the center of gravity of the elevator backward, which is compatible with the rearward installation of the car frame 2, reduces the torque on the elevator car, and runs more stably.

[0021] In this embodiment, the compact villa elevator also includes a traction rope 7, a traction machine 8, a counterweight body 9, a counterweight guide shoe 10, a counterweight guide rail 20 and a counterweight bracket 30. The counterweight bracket 30 is fixed on the rear side of the inside of the derrick 5. The counterweight bracket 30 extends in the up and down directions. The interior of the counterweight bracket 30 is provided with a space for the counterweight to move up and down. There are two counterweight guide rails 20, and the two counterweight guide rails 20 are relatively installed on the left and right sides of the inside of the counterweight bracket 30. The counterweight guide shoes 10 are installed on the left and right sides of the outside of the counterweight body 9. The counterweight guide shoes 10 correspond to the counterweight guide rails 20 for sliding cooperation. The counterweight body 9, the traction machine 8 and the car frame 2 are connected by the traction rope 7. The traction machine 8 is fixedly installed on the top of the derrick 5. By arranging the counterweight body 9, counterweight guide shoe 10, counterweight guide rail 20 and counterweight bracket 30 at the rear side of the well frame 5, so as to adapt them to the rearward arrangement of the car frame 2, the overall structure of the elevator is more compact and the space occupancy is smaller. When the elevator is running, the traction rope 7 is driven by the traction machine 8 to move, so that the counterweight body 9 slides up and down under the cooperation of the counterweight guide shoe 10 and the counterweight guide rail 20; the car body 1 and the car frame 2 slide up and down under the cooperation of the car guide shoe 3 and the car guide rail 4.

[0022] In this embodiment, a separation zone 40 is provided between the counterweight body 9 and the car body 1. A baffle 50 is installed within the separation zone 40. The left and right sides of the baffle 50 are respectively fixed to the left and right sides of the interior of the derrick 5. The baffles 50 are arranged from bottom to top, obscuring the mounting structure of the counterweight body 9 at the rear of the car body 1 and improving the aesthetics of the elevator. Furthermore, the baffles 50 can be fixed to the interior of the derrick 5 from top to bottom on both sides, making the installation of the baffles 50 more stable and preventing shaking caused by airflow during elevator operation. In this embodiment, the car frame 2 is connected to the rear of the car body 1, and the car guide rails 4 are arranged on the left and right sides of the car frame 2. The car frame 2 does not need to extend rearward. Therefore, installing the baffles 50 within the separation zone 40 allows the baffles 50 to be fixed to the left and right sides of the interior of the derrick 5, ensuring the stability of the baffle 50 installation without affecting the normal operation of the elevator.

[0023] Furthermore, the baffle 50 can be made of several unit plates spliced ​​from bottom to top, and the unit plates can be disassembled individually. When counterweight maintenance work is required, several unit plates can be disassembled and carried out, which is more convenient for counterweight maintenance work.

[0024] In this embodiment, the derrick 5 includes a front frame 51, a rear frame 52 and a reinforcement frame 53. The front frame 51 and the rear frame 52 are connected front and back by a splicing profile 54, and the splicing profile 54 extends from bottom to top; the reinforcement frame 53 is installed on the inner wall of the rear frame 52 to enhance the structural strength of the rear frame 52, and the car guide rails 4 and the counterweight bracket 30 are fixed on the inner wall of the reinforcement frame 53, so that the force-bearing structure in the derrick 5 is enhanced, and the part of the car body located in front of the installation part 11 is correspondingly arranged in the front frame 51, and the installation part 11 of the car body and the structural components of the rear side thereof are correspondingly arranged in the reinforcement frame 53. Therefore, on the structure of the derrick 5, the part of the derrick 5 that needs to be subjected to force is strengthened by setting the reinforcement frame 53, while the part that does not need to be subjected to force can be surrounded by the front frame 51, which can not only ensure the structural strength, but also effectively save material costs and increase the space of the car body 1.

[0025] In this embodiment, the front frame 51 includes front side panels 511 arranged opposite to each other on the left and right sides, the rear frame 52 includes rear side panels 521 arranged opposite to each other on the left and right sides, the splicing profile 54 includes a first connecting groove 541 for the edge of the front side panel 511 to be snapped into and fixed, a second connecting groove 542 for the edge of the rear side panel 521 to be snapped into and fixed, and a limiting ridge 543 for installation limiting the front side of the reinforcing frame 53, the first connecting groove 541 is located on the front side of the splicing profile 54, the second connecting groove 542 is located on the rear side of the splicing profile 54, the limiting ridge 543 is located on the inner side of the splicing profile 54, and the rear side of the limiting ridge 543 abuts against the front side of the reinforcing frame 53, thereby realizing installation limiting of the front side of the reinforcing frame 53. The outer wall of the reinforcing frame 53 is separated from the rear side plate 521, thereby preventing the reinforcing frame 53 from expanding outward and squeezing the rear side plate 521 under pressure, thereby causing deformation of the rear side plate 521. The reinforcing frame 53 is supported by the profile and has higher stability.

[0026] In this embodiment, the rear side of the rear frame 52 is provided with two relatively arranged rear connecting profiles 522 and a rear sealing plate 523 connected between the two rear connecting profiles 522. The rear connecting profile 522 extends from bottom to top, and the rear connecting profile 522 is a right-angle corner structure. A third connecting groove 524 is provided on one corner edge of the rear connecting profile 522 for the other edge of the rear side plate 521 to be snapped into and fixed. A fourth connecting groove 525 is provided on the other corner edge of the rear connecting profile 522 for the edge of the rear sealing plate 523 to be snapped into and fixed. The inner side of the rear connecting profile 522 abuts against the rear side of the reinforcing frame 53, so that the rear side of the reinforcing frame 53 is also installed and limited. The rear side of the reinforcing frame 53 is separated from the rear sealing plate 523, thereby preventing the rear sealing plate 523 from being squeezed and deformed by the reinforcing frame 53. At the same time, the left and right sides of the reinforcing frame 53 are respectively abutted against the inner sides of the splicing profiles 54 and the rear connecting profiles 522 located on the left and right sides of the rear frame 52 to achieve installation limitation on the left and right sides.
