Detailed ways

Please refer to FIG. 1 , firstly, the three-dimensional exploded view of the components of the lamp of the present invention will be described. Mainly set a tooth tube 12 in the straight tube 10, and set the lower cap 14, washer 16, rotating shaft 18 and fixed shaft 20 on the tooth tube 12 in sequence, and use the inner tooth washer 22 And the nut 24 is combined with the tooth tube 12 to fix the above-mentioned parts sleeved on the tooth tube 12, and then the bulb group 26 is placed above the fixed shaft 20, and the lamp cover 28 is combined with the external tooth portion 200 of the fixed shaft 20, Fix the bulb group 26 and assemble the lampshade 30 on the supporting arms 180 , 202 , 204 to form a lamp 1 .

Among the above-mentioned components, the main feature of the utility model is that the rotating shaft 18, the fixed shaft 20 and the elastic positioning member 50 between them, utilize the rotatable method to make the support arm 180 to be folded and unfolded for positioning, so as to change the volume and size for convenience. Storage, collection. Please refer to Fig. 2 and Fig. 3, Fig. 2 is to assemble the parts in Fig. 1 to form a frame body with three bracket arms 180, 202, 204, and at least one bracket arm 180 can be rotated and folded. , and when unfolded, the lampshade 30 can be placed on the supporting arms 180, 202, 204 by means of the supporting arms 180, 202, 204 and its positioning structure, as shown in FIG. 3 . The positioning structure can usually be implemented with the prongs 182, 206, 208 drawn in the figure, and can also be made into grooves on the support arms 180, 202, 204, and can even be segmented to combine lampshades of different specifications.

Please refer to Fig. 4 and Fig. 5 at the same time, one embodiment of the supporting arm rotation structure of the present utility model includes a rotating shaft 18, and the rotating shaft 18 has at least one supporting arm 180 extending outward, and has a The fixed shaft 20 provided by the moving shaft 18 is provided with a groove 184 and an elastic positioning member 50 on the joint surface of the rotating shaft 18 and the fixed shaft 20, so that the rotating shaft 18 can rotate at least one bracket arm 180 to displace. In this embodiment, 50 is composed of a ball 186 and a spring 188 disposed in the groove 184, and it can also be replaced by materials such as elastic plastic and rubber. In the state of use, each support arm 180, 202 should be unfolded, and the ball 186 is pushed out by the elasticity of the inner spring 188 in the groove 184 of the rotating shaft 18, so that the ball 186 is nested in the positioning point 210 of the fixed shaft 20 . (as shown in Figure 4), the bracket arms 180, 202 are in the state of unfolding and positioning; in the retracted state, the ball 186 breaks away from the positioning point 210 and is pressed into the groove 184 by the fixed shaft 20, and the ball 186 is separated from the positioning point 210 (as shown in FIG. 5 ), the support arm 180 can be rotated and retracted through the rotation of the rotation shaft 18, so that the support arm 180 becomes a state of rotation and retraction. Therefore, the rotating shaft 18 is sheathed on the lower cap 14 in a sheathing manner, so that the rotating shaft 18 can drive the supporting arm 180 to rotate. On the contrary, it can also be designed to transform the fixed shaft in this embodiment into a rotating shaft, which has the function of rotating.

Cooperating with the above-mentioned design, the groove 184, the ball 186 and the spring 188 can be selectively arranged on the joint surface of the rotating shaft 18 or the fixed shaft 20. For example, if the rotating shaft 18 is provided with the aforementioned groove 184, Then the ball 186 and the spring 188 will be arranged in the groove 184, and a positioning point 210 will be arranged on the opposite fixed shaft 20, and vice versa. Through Figure 6A and Figure 6B, you can understand more clearly the movement of the bracket arm rotating and folding. Please refer to Figure 6A with the bracket arm in Figure 4 for the unfolded and positioned state. Figure 6B can be used with the bracket arm in Figure 5 to rotate and retract. Please refer to the state together.

If as shown in Figure 6B, when the support arm 180 of the rotating shaft 18 is rotated and folded, the support arm 180 will lean against the support arm 202 of the fixed shaft 20, and the lampshade originally arranged on the support arms 180, 202, 204 30 can be easily removed toward a wider direction, as shown in FIG. 7 , and the lampshade 30 can be easily removed without disassembling the lamp frame or other components.

The aforementioned embodiments can be applied to lamps of various specifications, but in comparison, larger lamps may need to use external force to push the balls into the groove due to the longer support arm and the weight of the lampshade, so an auxiliary device is required. Please refer to FIG. 8 and FIG. 9 for another embodiment of the present utility model. Contrary to the previous embodiment, the groove 184, the ball 186 and the spring 188 are arranged on one end of the fixed shaft 20, and the positioning point 210 is arranged on the rotating shaft 18. At one end, a through hole 190 is provided at a position corresponding to the positioning point 210, and an elastic component 192 is sleeved and fixed in the through hole 190 by a fixing member 196, and the pushing tip 194 cooperates with the elastic component 192 to push against the ball 186. The ball 186 is pressed by the push pin 194 to disengage from the positioning point 210, and the rotating shaft 18 can drive the supporting arm 180 to rotate at this time.

Therefore, it can be understood from FIG. 10 and FIG. 11 that the actual operation is performed. The user presses the push pin 194 exposed outside the rotating shaft 18, and the push pin 194 is pushed to squeeze the elastic component 192 disposed in the through hole 190. At the same time, the push pin 194 also presses the ball 186, the ball 186 leaves from the positioning point 210 and the pressing spring 188 retracts into the groove 184 of the fixed shaft 20, and the lamp can use the rotating shaft 18 in the unlocked state. Drive the supporting arm 180 to rotate, and become the state of FIG. 11 .

Please refer to FIG. 12 for another embodiment of the present utility model. An elastic piece 40 is provided at the fixed shaft 20. The front end of the elastic piece 40 has a round end 400. The round end 400 is exposed from the opening 212 of the fixed shaft 20 to the fixed The shaft 20, the shrapnel 40 can replace the previously mentioned balls and springs, and cooperate with the rotating shaft 18. A through hole 190 is provided at a position corresponding to the positioning point 210, and a fixing piece 196 sets are provided in the through hole 190. An elastic component 192 is fixed. When the push pin 194 cooperates with the elastic component 192, it can be pushed against the round end 400. The round end 400 can be separated from the positioning point 210 due to the elasticity of the shrapnel 40. At this time, the rotating shaft 18 can drive The support arm 180 rotates.

Therefore, the user presses the push pin 194 exposed outside the rotating shaft 18, and the push pin 194 is pushed to squeeze the elastic component 192 arranged in the through hole 190, and at the same time, the push pin 194 also presses the round end 400 Because the shrapnel 40 is flexible, the round end 400 is lifted from the opening 212 and retracted into the fixed shaft 20. At this time, the lamp can use the rotating shaft 18 to drive the supporting arm 180 to rotate in the unlocked state. Instead, it becomes the state of FIG. 13 .
