[0025] like Figures 1 to 4As shown, the utility model proposes a lamp with a single-rope synchronous lifting mechanism, including a lampshade 1, at least one group of slide rail assemblies 2 symmetrically distributed relative to the axis of the lampshade 1, an inner lamp holder 3, a round table 4, a replaceable lamp plate 5, and a driving mechanism 6. The lampshade 1 is a hollow cylindrical tube, and the lower end of the inner wall of the lampshade 1 is slidably connected to the inner lamp holder 3 through at least one group of slide rail assemblies 2. When in use, a cylindrical lampshade 1 is arranged, and at least one group of symmetrically distributed slide rail assemblies 2 and a pair of limiting ropes 8 fixedly connected to the slide rail assemblies 2 and with the axis pointing to the axis of the lampshade 1 are passed through the lampshade 1. The inner lamp holder 3 drives the limiting rope 8 and then drives the slider 22 to slide upward together. The limiting rope 8 is preferably made of insulating material, so as to limit the inner lamp holder 3 and the inner lamp holder 3 and the lampshade 1 The insulating connection between them; the upper end portion of the inner wall of the lampshade 1 is fixedly connected to the round table 4, and when the inner lamp holder 3 slides to the uppermost portion, its upper end surface contacts the lower end surface of the round table 4 and conducts the circuit, and the replaceable lamp panel 5 is installed at the lower end of the inner lamp holder 3, and the driving mechanism 6 is fixedly arranged on the upper end surface of the round table 4 and is slidably connected to the inner lamp holder 3 through the traction rope 7 that passes through the round table 4; when in use, the driving mechanism 6 pulls the inner lamp holder 3 through the traction rope 7, thereby achieving the effect of sliding movement of the inner lamp holder 3 in the inner cavity of the lampshade 1, and when the traction rope 7 is not pulled, the inner lamp holder 3 and the slider 22 connected by the limit rope 8 slide downward to the bottom together due to the resistance of the elastic member 14, thereby achieving the state that the lamp is absolutely powered off when the lamp is repaired, thereby ensuring the safety of the maintenance personnel.

[0026] Furthermore, at least one group of slide rail assemblies 2 is fixedly connected to the lower portion of the inner tube wall of the lampshade 1 and is evenly distributed in a circumferential direction. The slide rail assembly 2 includes a slide rail 21 fixedly connected to the inner wall of the lampshade 1, a slider 22 slidably connected to the slide rail 21, and a pair of limiting ropes 8 fixedly connected to the slider 22 and with the axis pointing to the axis of the lampshade 1. The limiting ropes 8 are fixedly connected to the outer wall of the inner lamp holder 3, and the sliding direction of the slider 22 on the slide rail 21 is along the axial direction of the lampshade 1. When in use, the slider 22 that limits the inner lamp holder 3 slides along the axial direction of the lampshade 1 when the inner lamp holder 3 is pulled and slid, thereby achieving a real-time limiting effect on the inner lamp holder 3.

[0027] Furthermore, a support tube 9 is fixedly provided on the slide rail 21 and is sleeved on the limit rope 8, and the inner port of the support tube 9 is in conflict with the limit rope 8; when in use, when the limit rope 8 drives the slide rail 21 to slide up, the limit rope 8 will conflict with the support tube 9, so that the limit rope 8 will not swing greatly, and thus the inner lamp holder 3 will not move when it is limited by the limit rope 8.

[0028] Furthermore, the lower end of the inner lamp holder 3 has a bulb mounting groove 31, the inner ring wall of the bulb mounting groove 31 has a conductive ring surface 10, the inner top end of the bulb mounting groove 31 has a conductive plane 11, and the upper end surface of the inner lamp holder 3 has an inner conductive abutment convex ring 12 and an outer conductive abutment convex ring 13 around the axis, the inner conductive abutment convex ring 12 is connected to the conductive plane 11, and the outer conductive abutment convex ring 13 is conductive to the conductive ring surface 10; when in use, the inner lamp holder 3 is connected to the circuit on the replaceable lamp panel 5 through the conductive ring surface 10 and the conductive plane 11 in the bulb mounting groove 31.

[0029] Furthermore, the replaceable lamp tray 5 is installed in the bulb mounting groove 31, and the replaceable lamp tray 5 is slidably connected to the inner tube wall of the lampshade 1. When in use, the replaceable lamp tray 5 of different specifications can be replaced, and the inner tube wall of the lampshade 1 can limit the rotation of the replaceable lamp tray 5.

When the inner lamp holder 3 slides to the uppermost part, the inner conductive contact convex ring 12 conflicts with the inner conductive contact ring groove 41 to realize circuit conduction, and the outer conductive contact convex ring 13 conflicts with the outer conductive contact ring groove 42 to realize circuit conduction. When in use, when the traction rope 7 is pulled, the inner lamp holder 3 and the slider 22 connected by the limiting rope 8 slide upward together to realize that the inner lamp holder 3 conflicts with the inner conductive contact ring groove 41 and the outer conductive contact ring groove 42 at the lower part of the truncated cone 4, thereby realizing the circuit conduction state.

[0031] Furthermore, an elastic member 14 is fixedly arranged in the storage ring groove 43, and the lower end of the elastic member 14 is in conflict with the upper end of the inner lamp holder 3; when in use, when the traction rope 7 is not pulled, due to the interference effect of the elastic member 14, the elastic member 14 is in conflict with the inner lamp holder 3 and the slider 22 connected by the limiting rope 8 slides downward to the bottom together, thereby achieving the state of absolute power-off of the lamp when the lamp is repaired, thereby ensuring the safety of the maintenance personnel.

The elastic member 14 enables the inner lamp holder 3 and the slider 22 connected by the limiting rope 8 to slide upwards together when the traction rope 7 is pulled, so that the inner lamp holder 3 and the inner conductive contact ring groove 41 and the outer conductive contact ring groove 42 at the lower part of the truncated table 4 are in conflict with each other, thereby realizing the circuit conduction state; when the traction rope 7 is not pulled, the inner lamp holder 3 and the slider 22 connected by the limiting rope 8 slide downwards to the bottom due to the interference effect of the elastic member 14, thereby achieving the state where the lamp is absolutely powered off when being repaired, thereby ensuring the safety of the maintenance personnel.

[0033] The above-mentioned specific embodiments are only several preferred embodiments of the present invention.
