[0016] In order to make the technical problems, technical solutions, and beneficial effects solved by the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0017] The external solar panel structure of the outdoor battery camera in this embodiment is applied to the connection structure between the outdoor battery camera and the solar panel, ensuring the stable connection between the solar panel and the outdoor battery camera.

[0018] The home elevator is installed indoors. Compared with commercial elevators, its internal installation space is smaller. A home elevator generally includes a hoistway, a car arranged in the hoistway, a counterweight structure connected to the car, a driving device, and a driving assembly connecting the driving device to each component.

[0019] In this embodiment, as Figure 1 shown, the installation protection structure of this home elevator includes a car 10, a counterweight 20, a rail clamp 30, and a safety rope 40.

[0020] The car 10 is arranged in the hoistway, and a car door 11 is arranged on one side.

[0021] The counterweight 20 is arranged on one side or behind the car 10. Among them, taking the car door 11 as a reference, when the counterweight 20 is arranged opposite the car door 11, this counterweight is a rear-mounted counterweight; when the counterweight 20 is arranged on one side of the car door 11, this counterweight is a side-mounted counterweight. In this embodiment, the counterweight 20 is arranged in a rear-mounted manner, and the counterweight 20 is arranged behind the car 10. In other embodiments, according to on-site construction requirements or other needs, the counterweight 20 can be arranged on one side of the car 10.

[0022] A traction rope 21 is arranged between the counterweight 20 and the car 10. One end of the traction rope 21 is connected to the counterweight 20, and the other end is connected to the car 10. In addition, the traction rope 21 is sleeved on the first guide wheel assembly 22. The first guide wheel assembly 22 includes several guide wheels. Through the arrangement of the guide wheels, the follow-up of the counterweight 20 and the car 10 is realized.

[0023] The rail clamps 30 are respectively arranged at the top of the car 10 and the top of the counterweight 20, and can realize the stopping of the car 10 under the action of the gravity of the counterweight side 20.

[0024] One end of the safety rope 40 is connected to the rail clamp 30 at the top of the counterweight 20, and the other end is connected to the rail clamp 30 on the car 10. In addition, the safety rope 40 is sleeved on the second guide wheel assembly 41. The second guide wheel assembly 41 includes several guide wheels. Through the arrangement of the guide wheels, when the elevator and the traction rope 21 are both working normally, it assists in realizing the follow-up of the counterweight 20 and the car 10.

[0025] A cone sleeve is arranged at one end of the safety rope 40 connected to the rail clamp 30, and it is connected to the rail clamp 30 through this cone sleeve.

[0026] Based on the installation protection structure of this home elevator, the working principle of this protection structure is:

[0027] When the traction rope 21 breaks and cannot work, the car 10 will fall under the loss of the traction of the traction rope 21. At this time, under the action of the gravity on one end of the safety rope 40 on the counterweight 20 side, the cone sleeve on the car 10 side at the other end of the safety rope 40 is pulled, and the built-in wedge block in the rail clamp 30 on the car 10 side is driven through the cone sleeve. The rail clamp 30 is used to stop the car 10, so that the car 10 and the counterweight 20 are stuck on the guide rail, avoiding the fall of the car 20 and the occurrence of safety accidents.

[0028] In the installation protection structure of the household elevator according to the above embodiment, it includes a car, a counterweight, a rail clamp and a safety rope. Among them, the counterweight is connected to the car through a traction rope, the rail clamps are respectively arranged on the car and the counterweight, one end of the safety rope is connected to the car, and the other end is connected to the counterweight. Based on the installation protection structure of this household elevator, the counterweight and the car are connected by two components, namely the traction rope and the safety rope. Therefore, when the speed limiter of the elevator is invalid and all the traction ropes are disconnected, the car and the counterweight are not under traction and are in a free-falling state. At this time, the gravity of the car counterweight at one end of the safety rope drives the other end of the safety rope to lift the rail clamp at this end, and then stops the car and the counterweight, making them stuck on the guide rail, avoiding the car and the counterweight from bottoming out and causing safety accidents.

[0029] In addition, a cone sleeve is arranged at one end of the safety rope connected to the rail clamp, and the cone sleeve is connected to the pull plate of the rail clamp. Therefore, when the safety rope is under the gravity of the counterweight at one end, the pull plate in the rail clamp is pulled through the cone sleeve at the other end, and then the built-in wedge block of the rail clamp is driven, so as to realize the stopping function of the car and the counterweight.

[0030] In addition, both the traction rope and the safety rope are connected to the counterweight and the car through a guide wheel assembly. The follow-up of the car and the counterweight is realized by means of several guide wheels of the guide wheel assembly.

[0031] Obviously, those skilled in the art can make various changes and modifications to this application without departing from the spirit and scope of this application. Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalent technologies, this application also intends to include these changes and variations.
