Without a protective housing, these components are susceptible to damage or corrosion from physical and chemical factors in the environment, leading to a decrease in overall performance. Furthermore, the housing isolates the internal mechanical components and maintenance accessories from the external environment to prevent the ingress of dirt and impurities, preventing the ingress of dust and other impurities that could affect the machine's operation. Furthermore, the housing provides cushioning and protection against physical impact and damage, protecting the internal mechanical components from serious damage in the event of an accident such as a drop, thereby maximizing the integrity of the machine. Beyond enhancing the appearance, the housing also adds aesthetics and a sense of engineering design to the mechanical equipment, enhancing its quality.

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] Example:

[0021] See also Figure 1 - Figure 3 The present invention provides a technical solution: a shell with an anti-fall function, including a shell body 1, a rotating component 3 is rotatably connected to the shell body 1, an anti-fall component 6 is provided inside the shell body 1, a limiting component 7 is provided on the outside of the rotating component 3, a wire hole 4 is provided inside the shell body 1, an anti-wear pad 5 is provided inside the wire hole 4, and a mounting hole 2 is provided inside the shell body 1. The rotating component 3 includes a gear 31, the gear 31 is rotatably connected to the inside of the shell body 1, the inside of the gear 31 is fixedly connected to a rotating rod 32, and one end of the rotating rod 32 extends to the outside of the shell body 1, the outside of the rotating rod 32 is located inside the shell body 1 and is wound with a rope 33, and one end of the rope 33 extends to the outside of the wire hole 4, and the end of the rotating rod 32 away from the gear 31 is fixedly connected to a handwheel 34. By rotating the handwheel 34, when the handwheel 34 rotates, the gear 31 is driven to rotate through the rotating rod 32 connected thereto, and when the rotating rod 32 rotates, the rope 33 wound outside is driven to extend or shorten, thereby expanding the use limit.

[0022] Furthermore, the anti-fall component 6 includes an arc block 61, which is rotatably connected to the inside of the shell body 1, and one side of the arc block 61 contacts the outside of the gear 31. The inside of the shell body 1 is provided with a mounting groove 63, and the inside of the mounting groove 63 is provided with a spring 64. The inside of the shell body 1 and on one side of the mounting groove 63 are provided with a movable groove 65. The outside of the arc block 61 is fixedly connected to a movable plate 62, and the movable plate 62 extends to the outside of the movable groove 65 away from the side of the arc block 61. The bottom of the movable plate 62 is fixedly connected to the top of the spring 64. When in use, the shell body 1 is fixed with bolts through the provided mounting hole 2, and the movable plate 62 is manually moved upward in the mounting groove 63 along the movable groove 65. At this time, the spring 64 is deformed, driving the arc block 61 connected to the other side of the movable plate 62 to move outside. The shell body 1 rotates clockwise, and when the arc block 61 rotates, it loses contact with the gear 31. At this time, the gear 31 is in an active state, and the length of the rope 33 can be adjusted by the hand wheel 34. When the rope 33 is adjusted to a suitable length, the movable plate 62 can be manually loosened. At this time, it is reset by the spring 64, which will drive the movable plate 62 to move downward in the movable groove 65. At the same time, when the movable plate 62 moves downward, it will drive the arc block 61 to rotate counterclockwise. When the arc block 61 rotates to contact the outside of the gear 31, it will stop rotating and get stuck in the groove of the gear 31. In this way, the gear 31 can be positioned, thereby achieving the effect of falling for the rope 33, making it less likely to fall during use. It has a good fixing effect and has an anti-falling function, which enhances practicality and improves the use effect.

[0023] Furthermore, the limiting component 7 includes a support rod 71, and the two support rods 71 ​​are fixedly connected to the inside of the shell body 1. The top ends of the two support rods 71 ​​are fixedly connected with a fixed block 72. A limiting ring 73 is fixedly connected between the two fixed blocks 72 and outside the rope 33. When the rope 33 is extended or shortened, the rope 33 is limited in the limiting ring 73 through the setting of the limiting component 7, so that the rope 33 can be limited when it is stretched, reducing shaking and not easily shifting, thereby improving the use effect.

[0024] In summary: when in use, the shell body 1 is fixed with bolts through the provided mounting hole 2, and the movable plate 62 is manually moved upward along the movable groove 65 in the mounting groove 63. At this time, the spring 64 is deformed, driving the arc block 61 connected to the other side of the movable plate 62 to rotate clockwise in the shell body 1. When the arc block 61 rotates, it loses contact with the gear 31. At this time, the gear 31 is in an active state. By rotating the hand wheel 34, when the hand wheel 34 rotates, the gear 31 is driven to rotate through the rotating rod 32 connected thereto, and when the rotating rod 32 rotates, it drives the rope 33 wrapped around the outside to extend or shorten, thereby expanding the use limit. When the rope 33 is extended or shortened, the rope is set by the setting of the limit assembly 7. When the rope 33 is stretched, the rope 33 is limited in the limiting ring 73, so that the rope 33 is less shaken and less likely to shift when stretched, thereby improving the use effect. When the rope 33 is adjusted to a suitable length, the movable plate 62 can be manually loosened. At this time, the spring 64 is reset to drive the movable plate 62 to move downward in the movable groove 65. At the same time, when the movable plate 62 moves downward, it will drive the arc block 61 to rotate counterclockwise. When the arc block 61 rotates to contact the outside of the gear 31, it will stop rotating and get stuck in the groove of the gear 31. In this way, the gear 31 can be positioned, thereby achieving the effect of falling for the rope 33, making it less likely to fall during use. It has a good fixing effect and has an anti-falling function, which enhances practicality and improves the use effect.
