Detailed Description

For further understanding of the contents, features and effects of the present invention, the following embodiments will be exemplified in conjunction with the accompanying drawings as follows:

as shown in fig. 1 to fig. 3, the present embodiment provides a telescopic bracket for overhead lamps, which mainly comprises a fixing device, a double-scissors telescopic bracket, a lifting device and a locking device. The overall size of the telescopic bracket of the high-altitude lamp depends on the size of the lamp and the size of the original mounting bracket.

The fixing means includes an upper fixing plate 101 and a lower fixing plate 102. The upper fixing plate 101 is a frame structure surrounded by a top plate and two side plates, the upper part of the upper fixing plate is used for connecting an existing lamp bracket, and the lower part of the upper fixing plate is used for installing a lifting device. The lower fixing plate 102 is a frame structure surrounded by a bottom plate and two side plates, the lower part of the lower fixing plate is used for connecting a lamp, and the upper part of the lower fixing plate is used for connecting the tail end of a steel wire rope 110 of a lifting device and a hanging rod 112 in a mounting and locking device. A set of double cross-shearing type telescopic brackets are installed between the upper fixing plate 101 and the lower fixing plate 102, the upper parts and the lower parts of the double cross-shearing type telescopic brackets are respectively installed on two side plates of the upper fixing plate 101 and two side plates of the lower fixing plate 102, and meanwhile, both the two side plates of the upper fixing plate 101 and the two side plates of the lower fixing plate 102 are provided with slideways for the cross-shearing type telescopic brackets to move transversely.

The double-cross-shear type telescopic support is formed by hinging a plurality of fender boards 106, the extension length of the double-cross-shear type telescopic support can be flexibly adjusted through the number of the fender boards 106, and the length and the size of the fender boards 106 are determined according to the size of a lamp and the height of a site. The transverse distance between the two sets of the cross-shearing type supports is the same as the length of the lappet 106, and the two sets of the cross-shearing type supports form a square structure integrally. A plurality of horizontal rods 109 are arranged between the two sets of cross-shearing type supports, and two ends of each horizontal rod 109 are respectively connected to the hinged positions of the lappets 106 with the same height of the two sets of cross-shearing type supports, so that the two sets of cross-shearing type supports are kept synchronous in stretching, and the shaking of the supports is reduced. The outer sides of the lappets 106 are provided with ear plates as cable fixing holes 107 and with U-shaped connecting rods as cable tie bars 108, the cable fixing holes 107 serving to prevent the cable from being caught between the lappets 106 when the carriage is retracted. The cable tie bars 108 are used to secure the cables.

The lifting device is composed of a worm gear 103, a rotating rod 105, a winding wheel 104 and a steel wire rope 110. Two sides of the rotating rod 105 are respectively penetrated and connected to two side plates of the upper fixing plate 101, a worm wheel 103 is installed at one end of the rotating rod 105 outside the upper fixing plate 101, two winding wheels 104 with a certain distance are installed on the rotating rod 105 inside the upper fixing plate 101, steel wire ropes 110 are respectively wound on the two winding wheels 104, the two thin and soft steel wire ropes 110 are respectively wound in the two winding wheels 104 in a circle winding manner, the head end of each steel wire rope 110 is fixed to the winding wheel 104, and the tail end of each steel wire rope 110 is fixedly connected to the lower fixing plate 102. When the worm wheel 103 is rotated, the worm wheel 103 converts the horizontal rotation into the vertical rotation of the rotating rod 105, thereby driving the vertical rotation of the winding wheel 104, and the wire rope 110 is wound or released therewith.

The locking device is composed of a hook 111 and a hanging rod 112, the hook 111 is fixed in the middle of the rotating rod 105 of the lifting device, the hook 111 rotates along with the rotation of the rotating rod 105, and the hanging rod 112 can be hung or separated through the rotation.
