The lubricating gasket 9 is attached to the coil spring mounting case cover 8, and the lubricating gasket 9 increases the contact area, thereby reducing the abrasion of the rotating shaft 6. One end of the shaft 6 is fixed to a coil spring mounting case cover 8. The outer wall of the coil spring mounting shell 7 is attached to the inner wall of the wire rewinding device 2. A coil spring mounting housing cover 8 overlies the base 3. Base 3 sets up a plurality of screw grooves, and a plurality of screw holes are seted up to coil spring installation cap 8, and the quantity of screw hole is the same with the quantity in screw groove, and the screw passes screw hole and screw groove in proper order, links together coil spring installation cap 8 and base 3.

The base 3 is provided with a plurality of via holes for the suspension wires 4 to penetrate and extend. The opening direction of the through hole is tangent to the outer wall of the wire rewinding device 2.

Fig. 4 is a front view of the present invention, and fig. 5 is a sectional view taken along a-a in fig. 4. Referring to fig. 4 and 5, the coil spring 5 includes a winding body. The outer side end of the winding body is reversely bent towards the outer side to form a bending connecting part, the coil spring mounting shell 7 is provided with a vertical groove, and the bending connecting part is clamped in the vertical groove.

The coil spring 5 is a metal elastic element, the rotating shaft 6, the coil spring mounting shell 7 and the coil spring mounting shell cover 8 are all made of metal materials, and the lubricating gasket 9 is made of polytetrafluoroethylene materials. The wire rewinding device 2 and the base 3 are made of polyformaldehyde materials.

The utility model discloses an installation principle and theory of operation as follows:

the utility model is suitable for a messenger wire lamp. Firstly, a plurality of paths of suspension wires 4 are wound on the spiral groove of the wire rewinding device 2 and then penetrate through the through hole of the base 3, and the coil spring assembly 1 and the wire rewinding device 2 are coaxially arranged in the base 3.

The wire rewinding device 2 can wind the suspension wires 4 of different lines separately, and can be divided into a plurality of paths of suspension wires 4 connected with the suspension wire lamps. When the suspension wire lamp is manually lifted or pulled down, the suspension wire 4 rotates along the outer wall of the wire winding device 2, the coil spring 5 and the rotating shaft 6 rotate relatively, the coil spring 5 is wound on the rotating shaft 6 and stores kinetic energy, and the coil spring assembly 1 drives the wire winding device 2 to wind wires. When the external force disappears, the coil spring 5 generates torsion to drive the rotating shaft 6, and the coil spring assembly 1 drives the wire rewinding device 2 to rewind.

The stress condition of the messenger wire lamp is as follows: the self-gravity G, the friction force F between the suspension wire 4 and the wire rewinding device 2 and the elastic force F of the coil spring 5. When F is larger than G, the suspension wire 4 tends to shrink, and the friction force F prevents the suspension wire 4 from shrinking; when F is less than G, the suspension wire 4 tends to be pulled out, and the friction force F prevents the suspension wire 4 from being pulled out. To balance the height of the ceiling lamp and fix the ceiling lamp in the air, the following conditions can be obtained: G-F is more than F and less than G + F.

Because the hanging lamp can automatically and balancedly stop at a certain position in the air, the purpose of randomly adjusting the height of the hanging lamp is achieved.

In the description of the embodiments of the present invention, it should be further noted that unless explicitly stated or limited otherwise, the terms "disposed" and "connected" should be interpreted broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements.
