Description

Technical Field

[0001] The present invention relates to a lighting device, and more specifically, to a lamp body structure with adjustable length. Background Technology

[0002] Currently, there are many types and styles of light bulbs on the market, offering customers a wide range of choices. However, the length of the bulb body is generally fixed, while the depth of the light fixture used for installation often varies. Therefore, the selection of the bulb body is limited by the model of the light fixture. Because the bulb body length is fixed, it causes inconvenience for installation in many confined spaces. Summary of the Invention

[0003] To overcome the above shortcomings, the present invention provides a lamp body structure with adjustable length. The length of the lamp body can be adjusted so that it can be matched and installed with lamp barrels of various depths. The installation of the lamp body is not restricted by the model of the lamp barrel, which has good versatility and makes it more convenient to install the lamp body in many narrow spaces.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an adjustable lamp body structure, comprising an upper lamp body and a lower lamp body connected together, wherein the upper lamp body and the lower lamp body slide and nest together, and the upper lamp body and the lower lamp body move relative to each other to adjust the length of the entire lamp body.

[0005] In this patent, the upper and lower lamp bodies slide and nest together, allowing them to move relative to each other and adjust the overall length of the lamp body. During installation, the lamp body length is adjusted according to the depth of the lamp holder, ensuring a proper match and facilitating installation. The adjustable lamp body length of this application allows it to be installed with lamp holders of various depths, eliminating limitations based on lamp holder size and offering excellent versatility. This makes installation in confined spaces much easier.

[0006] Preferably, the lower lamp body is provided with a connecting groove, and the upper lamp body is provided with a connecting strip that fits the connecting groove. The connecting strip is nested in the connecting groove. The nesting of the connecting strip and the connecting groove ensures that the process of adjusting the length of the upper and lower lamp bodies is smooth and reliable.

[0007] Preferably, several positioning strips are evenly distributed around the lower lamp body, and the gap between two adjacent positioning strips in the circumferential direction forms a connecting groove; the gap between two adjacent connecting strips on the upper lamp body forms a positioning groove, and the positioning strips are adapted to the positioning grooves for connection.

[0008] This structural design makes the nesting between the upper and lower lamp bodies more reliable, and the forces during their movement are more balanced, preventing jamming.

[0009] Preferably, the positioning strip has a hollow structure. The hollow structure not only saves materials and reduces costs, but also allows the positioning strip to have a certain degree of elasticity, increasing the reliability of the connection between the upper and lower lamp bodies.

[0010] Preferably, guide rails are provided on both sides of the connecting groove, and guide grooves are provided on the side walls of the connecting strip, with the guide rails and guide grooves being adapted to each other.

[0011] During the movement of the upper and lower lamp bodies, the guide rails and guide grooves slide against each other, which facilitates the smooth movement of the upper and lower lamp bodies.

[0012] Preferably, the upper lamp body is provided with a snap-fit ​​connector, and the lower lamp body is provided with several slots spaced vertically apart. The snap-fit ​​connector can be snapped into any slot to achieve positioning of the upper and lower lamp bodies.

[0013] As the upper and lower lamp bodies are pulled and moved relative to each other, the locking connector can slide through the locking slot. Once the upper and lower lamp bodies are in position, the locking connector engages in the locking slot to position the connection between the upper and lower lamp bodies.

[0014] Preferably, the lower lamp body is provided with a snap-fit ​​plate, and the snap-fit ​​slot is set on the snap-fit ​​plate.

[0015] The card slot is located on the card connector plate, which is convenient and reliable.

[0016] Preferably, the snap-fit ​​connector has inclined guide surfaces at both the top and bottom. The guide surfaces on the snap-fit ​​connector allow the upper and lower lamp bodies to push and pull against each other, moving them closer and further apart, thus facilitating the adjustment of the lamp body length.

[0017] Preferably, the upper lamp body is provided with an elastic groove at the corresponding position of the snap-fit ​​connector. The elastic groove increases the elasticity of the snap-fit ​​connector, making it easier for the snap-fit ​​connector to engage and disengage from the snap-fit ​​connector.

[0018] Preferably, a positioning block that moves up and down is connected inside the elastic groove, and a lever is connected to the positioning block. A sliding groove is provided on the upper lamp body corresponding to the lever, and one end of the lever extends out of the sliding groove to the upper lamp body. A locking pin is installed on the snap-fit ​​connector, and one end of the locking pin has an inclined pushing surface, which is placed inside the elastic groove. A positioning spring is installed between the locking pin and the snap-fit ​​connector, and a locking hole is provided at the bottom of the snap-fit ​​groove. When the upper lamp body and the lower lamp body move into position, the snap-fit ​​connector is snapped into the snap-fit ​​groove, and the lever is pushed to move the positioning block downward. The positioning block abuts against the pushing surface and pushes the locking pin toward the locking hole, and the end of the locking pin is inserted into the locking hole.

[0019] After the lamp body length is adjusted to the correct position, the locking connector engages in the slot. Pushing the lever downwards moves the positioning block downwards, causing it to abut against the pushing surface and push the locking pin towards the locking hole. The end of the locking pin is then inserted into the locking hole. As the positioning block moves downwards to the locking connector position, the locking connector loses its elasticity, making it difficult for the upper and lower lamp bodies to be pulled apart. Furthermore, the locking pin, now inserted in the locking hole, further locks the upper and lower lamp bodies together, preventing them from being pulled apart. When further adjustment of the lamp body length is needed, pushing the lever upwards moves the positioning block to the top. Under the action of the positioning spring, the locking pin returns to its original position, and the end of the locking pin disengages from the locking hole. At this point, the locking connector is elastic, facilitating movement and adjustment between the upper and lower lamp bodies.

[0020] Compared with the prior art, the beneficial effects of the present invention are: (1) The length of the lamp body structure of the present application can be adjusted so that the lamp body can be matched and installed with lamp barrels of various depths. The installation of the lamp body is not restricted by the model of the lamp barrel and has good versatility; (2) The length of the upper lamp body and the lower lamp body is easy to adjust. After the length is adjusted to the right position, reliable positioning can be achieved, avoiding slippage between the upper lamp body and the lower lamp body. Attached Figure Description

[0033] In this patent, the upper and lower lamp bodies slide and nest together, allowing them to move relative to each other and adjust the overall length of the lamp body. During installation, the lamp body length is adjusted according to the depth of the lamp holder, ensuring a proper match and facilitating installation. The adjustable lamp body length of this application allows the lamp body to be installed with lamp holders of various depths, making installation not limited by the lamp holder model and offering good versatility.

[0034] Example 2: A lamp body structure with adjustable length (see appendix) Figure 6 Appendix Figure 7 Its structure is similar to that of Embodiment 1, with the main difference being that in this embodiment, a positioning block 21 that moves vertically is connected inside the elastic groove, a lever 22 is connected to the positioning block, a sliding groove 23 corresponding to the lever is provided on the upper lamp body, and one end of the lever passes through the sliding groove to the upper lamp body; a locking pin 24 is installed on the snap-fit ​​connector, one end of the locking pin has an inclined pushing surface 25, the pushing surface is placed in the elastic groove, a positioning spring 26 is installed between the locking pin and the snap-fit ​​connector, and a locking hole 27 is provided at the bottom of the snap-fit ​​groove; an upper magnetic sheet 28 is installed at the upper end of the elastic groove on the connecting strip, and a lower magnetic sheet 29 is connected to the upper end of the positioning block, the upper magnetic sheet and the lower magnetic sheet attract each other. The snap-fit ​​connector has a mounting hole 30, one end of the mounting hole has a flange 31, the other end of the mounting hole is connected to a limiting ring 32, a positioning protrusion 33 is provided on the outer wall of the locking pin, the positioning protrusion 33 is adapted to the mounting hole, the positioning spring abuts between the positioning protrusion 33 and the flange, and the positioning protrusion abuts against the limiting ring.

The other end of the locking pin retracts into the opening of the mounting hole, and the edge of this end of the locking pin has a chamfer for guidance. When the upper and lower lamp bodies are moved into position, the locking connector engages with the slot. The pushing lever moves the positioning block downwards, and the positioning block abuts against the pushing surface, pushing the locking pin towards the locking hole. The end of the locking pin is then inserted into the locking hole. Other structural features are the same as in Embodiment 1.

[0035] After the lamp body length is adjusted to the correct position, the locking connector engages in the slot. Pushing the lever downwards moves the positioning block downwards, causing it to abut against the pushing surface and push the locking pin towards the locking hole. The end of the locking pin is then inserted into the locking hole. As the positioning block moves downwards to the locking connector position, the locking connector loses its elasticity, making it difficult for the upper and lower lamp bodies to be pulled apart. Furthermore, the locking pin, now inserted in the locking hole, further locks the upper and lower lamp bodies together, preventing them from being pulled apart. When further adjustment of the lamp body length is needed, pushing the lever upwards moves the positioning block to the top. Under the action of the positioning spring, the locking pin returns to its original position, and the end of the locking pin disengages from the locking hole. At this point, the locking connector is elastic, facilitating movement and adjustment between the upper and lower lamp bodies.
