[0017] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.

[0018] Reference Figures 1 to 3A protective device for preventing chandeliers from falling includes a base 1, a connector 11 located at the bottom of the base 1, and a chandelier frame 2 mounted on the connector 11. To prevent the chandelier frame 2 mounted on the base 1 from falling and posing a serious safety threat to people and property, a cavity 12 is provided inside the base 1. A connecting ring 3 that can move horizontally is provided within the cavity 12. A through hole 13 communicating with the cavity 12 is provided on the side wall of the base 1. Several anti-fall chains 4 extend through the through holes 13 and connect to the chandelier frame 2 on the outer side of the connecting ring 3. The anti-fall chains 4 are in a slack state. Hanging rings for connecting the anti-fall chains 4 are provided on the connecting ring 3 and the chandelier frame 2. Thus, when the chandelier frame 2 falls from the base 1, it can be held in place by the anti-fall chains 4, preventing it from falling. Simultaneously, the anti-fall chains 4 can also serve as decorative chains under normal circumstances. To prevent the fall chain 4 from being subjected to excessive force or one of the fall chains 4 from being easily broken when it pulls the chandelier 2, a fixed seat 14 is provided on the base 1 and inside the cavity 12. The connecting ring 3 is fitted onto the fixed seat 14. A buffer structure 5 is provided between the connecting ring 3 and the fixed seat 14 to prevent the connecting ring 3 from moving. This buffers the tension on the fall chain 4 and balances the tension on each fall chain 4, making it less likely for the fall chain 4 to break.

[0019] In this design, the buffer structure 5 includes several first connecting holes 51 located inside the connecting ring 3, several second connecting holes 52 located outside the fixing base 14 and corresponding to the first connecting holes 51, and a spring 53 located between the first connecting holes 51 and the second connecting holes 52, thereby using the elastic force of the spring 53 to provide a buffering effect. Furthermore, there are at least three fall arresting chains 4, and the number of first connecting holes 51 and second connecting holes 52 corresponds to the number of fall arresting chains 4. Additionally, the center lines of the first connecting holes 51, second connecting holes 52, and through holes 13 are aligned on the same straight line, thus better balancing the tension on each fall arresting chain 4.

[0020] In this design, a boss 15 is provided inside the cavity 12 and near the side wall. The boss 15 is provided with a guide groove 16 that communicates with the through hole 13 and can guide the fall arrest chain 4, so as to prevent the fall arrest chain 4 from shifting inside the cavity 12, resulting in different tension on each fall arrest chain 4.

[0021] In this design, the through hole 13 and the end near the outer side of the base 1 is an arc surface 131, which facilitates the turning of the anti-fall chain 4 after it extends out of the through hole 13, reducing friction and thus reducing its impact on the force on the anti-fall chain 4.

[0022] In this design, a cover plate 6, which mates with the seat body 1 to form a cavity 12, is threadedly connected to the fixed base 14 to restrict the horizontal movement of the connecting ring 3 within the cavity 12. To reduce friction during the movement of the connecting ring 3 within the cavity 12 and thus lessen its impact on the force on the fall arrestor chain 4, grooves 31 are provided on both the upper and lower sides of the connecting ring 3. Each groove 31 contains a ball bearing 32, and the cross-section of the groove 31 is semi-circular, allowing the upper side of the connecting ring 3 to roll with the cover plate and the lower side to roll with the seat body 1.

[0023] In this solution, a ceiling cover 7 is connected to the base 1 inside and above the cover plate via a threaded connection. The base 1 is then mounted on the wall via the ceiling cover 7, and a pendant light bracket 2 is mounted on the base 1 to hang the light bulb.

[0024] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
