DETAILED DESCRIPTION

[0025] The following is combined with Figure 1-5 The utility model is described in further detail.

[0026] Reference Figure 1 and Figure 2 A spring contact lamp comprises a bottom cover 1, a lamp shade 2 is connected to the bottom cover 1, and the lamp shade 2 and the bottom cover 1 form a bulb. A shell 3 is provided on the side of the bottom cover 1 away from the lamp shade 2, and a turning seat 4 is provided on the shell 3. A joint 5 is threadedly connected to the turning seat 4, and the joint 5 is a connecting piece for connecting the lamp holder.

[0027] Reference Figure 2 and Figure 3 The shell 3 includes an upper cover 31 and a bottom plate 32. The bottom plate 32 is arranged on the side of the upper cover 31 facing the bottom cover 1. A fixing pin 21 is fixed on the side of the bottom plate 32 facing the upper cover 31. A fixing hole 22 for inserting the fixing pin 21 is opened on the side of the upper cover 31 facing the bottom plate 32. By inserting the fixing pin 21 into the fixing hole 22, the upper cover 31 and the bottom plate 32 can be connected to form a box body with an internal chamber.

[0028] Reference Figure 2 and Figure 4 A first conductive sheet 6 is fixed on the side of the bottom cover 1 facing the bottom plate 32, and the top surface of the first conductive sheet 6 is flush with the top surface of the bottom cover 1. A fixing tube 8 is fixed on the side of the bottom plate 32 facing the upper cover 31, and a guide groove 10 is provided on the side wall of each fixing tube 8, and a second conductive sheet 7 is provided in each fixing tube 8. A power converter 24 is installed in the upper cover 31, and the power converter 24 is electrically connected to the second conductive sheet 7 through a wire or the like, and is also electrically connected to the connector 5 through a wire or the like. After the connector 5 is connected to the lamp holder, the current can be transmitted to the second conductive sheet 7 through the connector 5. The second conductive sheet 7 extends into the guide groove 10, so that the second conductive sheet 7 can slide up and down along the guide groove 10. A contact portion 17 is provided on one side of the second conductive sheet 7 facing the first conductive sheet 6, and the contact portion 17 is obtained by the second conductive sheet 7 protruding toward the first conductive sheet 6, that is, when the second conductive sheet 7 slides to the end of the guide groove 10 close to the first conductive sheet 6, the contact portion 17 of the second conductive sheet 7 can protrude from the surface of the bottom plate 32 and connect with the first conductive sheet 6 for electrical conduction.

[0029] Reference Figure 2 , an elastic member is provided in the fixing cylinder 8. In this specific embodiment, the elastic member is specifically a spring 9. In some other embodiments, it can also be an elastically deformable element such as a rubber block. The spring 9 is in a compressed state, one end of the spring 9 abuts against the inner wall of the upper cover 31, and the other end abuts against the second conductive sheet 7, so that the second conductive sheet 7 always obtains a thrust to slide toward the first conductive sheet 6. After the first conductive sheet 6 and the second conductive sheet 7 are connected, the stability of the connection between the first conductive sheet 6 and the second conductive sheet 7 is maintained.

[0030] Reference Figure 2 A card block 11 is fixed on the outer wall of the upper cover 31, and a card strip 12 is fixed on the side of the bottom cover 1 facing the upper cover 31. Two card strips 12 are arranged at intervals, and a card slot 13 is provided on the side wall facing the card strip 12. The card block 11 can slide in the card slot 13. By sliding the card block 11 into the card slot 13, the upper cover 31 can be connected to the bottom cover 1, so that the first conductive sheet 6 and the second conductive sheet 7 are fitted. A stopper 14 is fixed at one end of the card strip 12, and the stopper 14 limits the sliding distance of the upper cover 31. When the card block 11 slides in the card slot 13, the stopper 14 blocks the further movement of the upper cover 31, so that the card block 11 cannot slide further in the card slot 13. At the same time, the block 14 also positions the upper cover 31. When the side wall of the upper cover 31 fits with the side wall of the block 14, the first conductive sheet 6 and the second conductive sheet 7 are abutted against each other, eliminating the process of repeatedly sliding the upper cover 31 to cause the first conductive sheet 6 and the second conductive sheet 7 to be conductive, thereby improving the connection efficiency between the first conductive sheet 6 and the second conductive sheet 7.

[0031] Reference Figure 3 and Figure 5 The end of the upper cover 31 away from the bottom plate 32 is provided with a steering seat 4, and a slider 16 is fixed on the side of the steering seat 4 facing the upper cover 31. A steering groove 15 for the slider 16 to slide is provided on the side of the upper cover 31 facing the steering seat 4. The steering groove 15 is in the shape of a circular ring, that is, the steering groove 15 is in the shape of a circular ring with an opening. When the connector 5 is connected to the lamp holder, the bulb needs to be rotated so that the bulb drives the connector 5 to rotate, thereby screwing the connector 5 into the lamp holder. Therefore, it is necessary to limit the sliding of the slider 16 to ensure the smooth connection between the connector 5 and the lamp holder.

[0032] Reference Figure 3 and Figure 5The end of the steering seat 4 facing the upper cover 31 is provided with a connecting portion 18, and a snap ring 19 is provided on the outer wall of the connecting portion 18. The upper cover 31 is provided with a plug hole 23 for inserting the connecting portion 18 and the snap ring 19, and a blocking portion 20 is provided in the plug hole 23 to prevent the snap ring 19 from escaping from the plug hole 23. The outer diameter of the snap ring 19 gradually decreases in the direction away from the steering seat 4, so that the snap ring 19 is easy to insert into the plug hole 23. The inner diameter of the blocking portion 20 is slightly smaller than the maximum outer diameter of the snap ring 19, so that after the snap ring 19 moves to the bottom end of the blocking portion 20, it is difficult to escape from the blocking portion 20, so that the steering seat 4 and the upper cover 31 can rotate relative to each other while maintaining the connection stability between the steering seat 4 and the upper cover 31.

[0033] The implementation principle of the embodiment of the utility model is as follows: when connecting the spring contact lamp to the lamp holder, insert the connector 5 into the lamp holder and rotate the bulb. When the slider 16 abuts against the inner wall of the steering groove 15, the bulb drives the connector 5 to rotate, so that the connector 5 connects the bulb to the lamp holder. After the connection between the bulb and the lamp holder is completed, rotate the bulb in the opposite direction to adjust the direction of the bulb.

[0034] The above are all preferred embodiments of the present utility model, and are not intended to limit the protection scope of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the protection scope of the present utility model.
