Detailed implementation manners

[0018] Please refer to Figures 1 to 4 , the present invention provides a decorative colored light hanging auxiliary device, including a lifting platform 101, a guardrail 102, a baffle 103 and a hook 104. The guardrail 102 is fixedly connected to the lifting platform 101 and is located above the lifting platform 101. The baffle 103 is fixedly connected to the guardrail 102 and is located below the guardrail 102. The hook 104 is fixedly connected to the baffle 103 and is located below the baffle 103;

[0019] It further includes the lifting assembly. The lifting assembly includes a bottom plate 105, a telescopic tube 106, a telescopic rod 107, and an auxiliary plate 108. The telescopic rod 107 is fixedly connected to the lifting platform 101 and is located below the lifting platform 101. The telescopic tube 106 is slidably connected to the telescopic rod 107 and wraps the telescopic rod 107. The bottom plate 105 is fixedly connected to the telescopic tube 106 and is located below the telescopic tube 106. The auxiliary plate 108 is fixedly connected to the bottom plate 105 and is located below the auxiliary plate 108.

[0020] In this embodiment, the bottom plate 105 can provide support for the whole device. The telescopic rod 107 can slide inside the telescopic tube 106, which can improve the stability during the height adjustment of the lifting platform 101. The auxiliary plate 108 can fix the position of the screw rod 110 and assist the screw rod 110 in rotating.

[0021] Furthermore, the motor 109 is fixedly connected to the bottom plate 105 and is located above the bottom plate 105. The screw rod 110 is fixedly connected to the output end of the motor 109 and is located inside the auxiliary plate 108. And the thread directions of the two ends of the screw rod 110 are opposite. Both of the two moving blocks 111 are threadedly connected to the screw rod 110 and are respectively located at the two ends of the screw rod 110. One end of each support rod 112 is rotatably connected to the corresponding moving block 111 and is located inside the corresponding moving block 111. Each fixing block 113 is rotatably connected to the corresponding support rod 112 and is located at the other end of the corresponding support rod 112. And both of the two fixing blocks 113 are fixedly connected to the lifting platform 101.

[0022] In this embodiment, starting the motor 109 can drive the screw rod 110 to rotate with the assistance of the auxiliary plate 108. The screw rod 110 will drive the two moving blocks 111 to move towards each other. The two moving blocks 111 will drive one end of the two support rods 112 to move. The other end of the support rod 112 will move up and down, thereby driving the two fixing blocks 113 to move up and down to change the height of the lifting platform 101.

[0023] Furthermore, the ladder 114 is fixedly connected to the guardrail 102 and is located outside the guardrail 102. The protective sleeve 115 is fixedly connected to the ladder 114 and wraps the ladder 114.

[0024] In this embodiment, the ladder 114 can facilitate workers to climb onto the lifting platform 101. The protective sleeve 115 can increase the friction force when workers climb the ladder 114 and prevent workers from slipping and falling from a height.

[0025] Furthermore, the base 116 is fixedly connected to the bottom plate 105 and is located below the bottom plate 105. The universal wheels 117 are fixedly connected to the base 116 and are located below the base 116.

[0026] In this embodiment, the base 116 connects the universal wheels 117 to the bottom plate 105. The universal wheels 117 reduce the friction when the device moves, and at the same time, increase the freedom degree when the device moves.

[0027] Furthermore, the connecting plate 118 is fixedly connected to the base 116 and is located outside the base 116. The fixing rod 119 is threadedly connected to the connecting plate 118 and penetrates through the connecting plate 118. The knob 120 is fixedly connected to the fixing rod 119 and is located above the fixing rod 119. The pressing plate 121 is fixedly connected to the fixing rod 119 and is located below the fixing rod 119.

[0028] In this embodiment, rotating the knob 120 drives the fixing rod 119 to rotate. The fixing rod 119 will press down the pressing plate 121. After the pressing plate 121 contacts the ground, the friction of the device will be increased, preventing the device from moving when the worker is operating, so as to prevent the worker from falling on the lifting platform 101.

[0029] When using the decorative color lamp hanging auxiliary device of this embodiment, when specifically using it, start the motor 109 to drive the screw rod 110 to rotate. The screw rod 110 drives the two moving blocks 111 to move towards each other through the threads with opposite helix directions at both ends, so that one end of the two support rods 112 starts to move, and at the same time, drives the up and down movement of the two fixing blocks 113 through the other end of the support rod 112, so as to drive the lifting platform 101 to lift. This method can change the height of the lifting platform 101 while reducing the rotating pairs involved in the lifting assembly.

[0030] The above-disclosed is only a preferred embodiment of the present invention. Of course, it cannot be used to limit the scope of the rights of the present invention. Those of ordinary skill in the art can understand all or part of the processes of implementing the above embodiments, and the equivalent changes made according to the claims of the present invention still fall within the scope covered by the present invention.
