[0015] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0016] The structure currently used to adjust the height of the dimming rod is composed of a transfer spur gear 1, a connecting rod 2 and a transfer side gear 3. This structure is installed on the lamp rear housing 6, and the connecting rod 2 and the transfer spur gear 1 are not integrated. They need to be assembled first, and then the height of the connecting rod 2 is adjusted by rotating the transfer spur gear 1 and the transfer side gear 3, so that the height of the dimming rod is adjusted, thereby achieving the purpose of dimming. However, when the structure is actually dimming, the transfer spur gear 1 is prone to skipping teeth, which will cause the transfer side gear 3 to collapse and fail to dim.

[0017] See also Figure 1-3 The technical solution provided by the utility model is: a new structure for adding a pressure cover device, including a transfer spur tooth 1, a connecting rod 2, a transfer side tooth 3 and a pressure cover 4, one end of the connecting rod 2 is connected to the transfer spur tooth 1, and the other end is connected to the transfer side tooth 3. Since the connecting rod 2 and the transfer spur tooth 1 are integrated, the number of structural components is reduced compared with the original, the assembly is more efficient, and the production time of the enterprise can be saved. The transfer side tooth 3 is provided with a tooth 31 inclined downward, and the tooth 31 supports the end of the connecting rod 2. The pressure cover 4 is located below the transfer spur tooth 1 and the connecting rod 2 and presses the transfer spur tooth 1 in the X direction, so that in the actual adjustment process, the transfer spur tooth 1 and the connecting rod 2 are pressed in the X direction by the pressure cover 4, and the transfer spur tooth 1 will not jump teeth. The transfer side tooth 3 and the transfer spur tooth 1 drive the connecting rod 2 to adjust the height together. The structure has good stability and durability. The adjustment principle is: by adjusting the transfer spur teeth 1 and the transfer side teeth 3, the height of the connecting rod 2 is adjusted, and then the height of the dimming rod in contact with the connecting rod 2 is adjusted to achieve the purpose of dimming.

[0018] Specifically, a block 11 is provided on the adapter spur tooth 1, and the block 11 is located inside one end of the connecting rod 2. The adapter spur tooth 1 and the connecting rod 2 are integrally formed by injection molding. The other end of the connecting rod 2 that contacts the adapter side tooth 3 is an inclined surface 22 that is axially inclined from both sides toward the middle of the connecting rod 2. The inclined surface 22 matches the tooth 31. The adapter spur tooth 1 and the adapter side tooth 3 are reliably connected to the connecting rod 2, making it more stable and durable during dimming. A raised structure is also provided above and below the connecting rod 2 near the connecting rod 2 that contacts the adapter side tooth 3 to facilitate installation on the rear housing 6 of the lamp.

[0019] Specifically, a notch 21 is provided on the lower side of the connecting rod 2, a protrusion 42 matched with the notch 21 is provided on the pressure cover 4, a groove 41 is provided on one end of the pressure cover 4, the groove 41 is matched with the transfer spur tooth 1, and a protrusion 2 43 is provided on the other end of the pressure cover 4, the protrusion 2 43 contacts the connecting rod 2, the connecting rod 2 is integrated, and the connecting rod 2 and the transfer spur tooth 1 are integrally formed, so the groove 41 on the pressure cover 4 is matched with the bottom of the transfer spur tooth 1 in the X direction and the pressure cover 4 is pressed in the X direction of the transfer spur tooth 1, and the setting of the protrusion 2 43 is also to increase the X-direction pressing force of the pressure cover 4, thereby improving the stability and durability during dimming.

[0020] The installation process of the utility model is as follows: first, the transfer spur gear 1 and the connecting rod 2 are integrally formed by injection molding, and the structure of the connecting rod 2 is also integral. At this time, the transfer spur gear 1 and the connecting rod 2 are installed together on the lamp rear shell 6, the structure is reduced, the installation is simple, and the operation is convenient; then the transfer side gear 3 is installed on the other end of the connecting rod 2 and the transfer side gear 3 is also installed on the lamp rear shell 6, at this time, the teeth 31 on the transfer side gear 3 are in contact with the inclined surface 22 on the connecting rod 2, the transfer spur gear 1 is located in the middle of the lamp rear shell 6, and the transfer side gear 3 is located on the side of the lamp rear shell 6; finally, the pressure cover 4 is installed on the transfer spur gear 1 and the connecting rod 2, and is locked by the screw 5, at this time, the groove 41 matches the surface of the transfer spur gear, the protrusion 1 42 matches the recess 21, and the protrusion 2 43 also presses the middle of the connecting rod 2. When dimming, due to the addition of the pressure cover 4, the dimming is more stable and durable, the quality of the product is improved, and the production time cost of the enterprise is saved.
