Description

Technical Field

[0001] The utility model belongs to the technical field of lamps, and in particular relates to a lamp holder structure. Background Art

[0002] Lamps are common in our daily life, and people cannot live without them. With the continuous improvement of people's living standards, they are no longer satisfied with simple lighting, and the atmosphere and shape brought by lamps are becoming more and more popular.

[0003] Especially for lamps with angular structures, the lighting effects at different angles are different. If the angle of the lampshade needs to be adjusted, the entire lamp needs to be disassembled, which is more troublesome. If the lampshade can be rotated and adjusted on the lamp holder, its applicability will be greatly improved. Utility Model Content

[0004] In order to solve the technical problem that the lampshade in the lamp in the background art is inconvenient to rotate, the purpose of the utility model is to provide a lamp holder structure that can solve the above problem.

[0005] The technical solution for achieving the purpose of the utility model is: a lamp holder structure, including a lamp cap, and a connecting sleeve, a mounting sleeve, and a sealing cover coaxially installed on the lamp cap in sequence; the sealing cover is installed on the first end of the mounting sleeve, and a mounting cavity is formed between the sealing cover and the mounting sleeve, one end of the connecting sleeve is fixed to the lamp cap, the other end of the connecting sleeve is installed through the second end of the mounting sleeve and is limited in the mounting cavity by a limiting device, and the connecting sleeve and the mounting sleeve can rotate relative to each other; the lampshade is fixed on the mounting sleeve.

[0006] In this solution, the lamp holder and the connecting sleeve are fixed and do not rotate, the installation sleeve and the sealing cover are fixed and do not rotate, the installation sleeve and the connecting sleeve are connected by a limit device, and the two can rotate relative to each other, and the lampshade is fixed on the installation sleeve, so when the lampshade needs to be rotated, it is only necessary to fix the connecting sleeve and rotate the installation sleeve, or fix the installation sleeve and rotate the connecting sleeve to achieve the purpose of rotating the lampshade. Specifically, a circuit board is installed in the connecting sleeve, a power line is connected to the lamp holder and connected to the circuit board, and the filament in the lampshade extends into the connecting sleeve through the sealing cover and the installation sleeve, and is connected to the circuit board, so that the internal power supply of the lamp is connected and the filament is lit. Since the filament has a certain redundant length, when the lampshade is rotated to a certain angle, the filament will not be twisted and fall off the circuit board, which improves the applicability of the overall lamp when the lampshade needs to be rotated.

[0007] Further, the limiting device is a first circumferential boss provided on the outer wall of the connecting sleeve, a second circumferential boss corresponding to the first circumferential boss provided on the inner wall of the mounting sleeve, the first circumferential boss and the second circumferential boss are clamped together, the first circumferential boss is located between the second circumferential boss and the sealing cover; the end of the connecting sleeve away from the lamp holder abuts against the bottom wall of the sealing cover. That is to say, after the first circumferential boss is clamped together with the second circumferential boss, the second circumferential boss limits the connection sleeve from being taken out from the second end of the mounting sleeve, and at the same time, the end of the connecting sleeve abuts against the bottom wall of the sealing cover, thus realizing the connection and fixation of the connecting sleeve and the mounting sleeve.

[0008] Furthermore, a limiting protrusion is provided on the first circumferential boss, and a limiting step corresponding to the limiting protrusion is provided on the second circumferential boss, which is used to limit the circumferential rotation angle of the limiting protrusion to prevent the connecting sleeve and the mounting sleeve from rotating too much in the same direction, thereby preventing the filament from falling off the circuit board after being twisted.

[0009] Furthermore, there are two limit steps, and the limit protrusion rotates between the two limit steps. The minimum angle between the two limit steps and the center of the second circular boss is not greater than 180°, that is, the maximum relative rotation angle between the connecting sleeve and the mounting sleeve is 180°, ensuring that the filament will not fall off the circuit board after being twisted.

[0010] Furthermore, the end of the connecting sleeve away from the lamp holder has a first annular protrusion, and the connecting sleeve contacts the bottom wall of the sealing cover through the first annular protrusion; the first circumferential boss is provided with a second annular protrusion, and the first circumferential boss is clamped with the second circumferential boss through the second annular protrusion. In other words, the connecting sleeve and the sealing cover are in contact with each other by relying on the first annular protrusion, and the first circumferential boss and the second circumferential boss are in contact with each other by relying on the second annular protrusion, thus reducing the contact area between them, reducing the rotational friction of the connecting sleeve in the installation cavity, and facilitating the rotation of the lampshade.

[0011] Furthermore, an elastic buckle is provided on the side wall of the sealing cover, and a slot corresponding to the elastic buckle is provided on the inner wall of the mounting sleeve. The elastic buckle is snapped into the slot to achieve the connection and fixation between the sealing cover and the mounting sleeve. The buckle connection is convenient and flexible.

[0012] Furthermore, a guide groove corresponding to the card slot is provided on the inner wall edge of the first end of the installation sleeve, and a guide slope is provided in the guide groove. When the sealing cover is connected to the installation sleeve, the guide groove can be used for quick positioning, and the guide slope helps the elastic buckle to be inserted into the card slot.

[0013] Furthermore, the lamp holder further comprises a filament mounting part, the filament mounting part comprises a first channel, a second channel and a third channel which are interconnected, the sealing cover comprises a mounting hole, the first channel is mounted in the mounting hole, the two poles of the filament respectively pass through the second channel and the third channel and then are connected to the connecting sleeve through the first channel. The filament mounting part is used to protect the filament from being twisted to other components in the lamp holder when the lampshade rotates, causing the filament to fall off from the circuit board.

[0014] Furthermore, the outer walls of the connecting sleeve and the mounting sleeve, and the inner walls of the lamp holder and the lamp shade are all provided with threads, the lamp holder and the connecting sleeve are fixed by threads, and the mounting sleeve and the lamp shade are fixed by threads. The method of fixing by threads is quick and convenient, conforms to the fixing method of most lamps, and does not increase the cost of the fixing structure.

[0015] Furthermore, the second end of the mounting sleeve also has a cap body, and the cross-sectional diameter of the cap body gradually decreases from the lampshade side to the connecting sleeve side. The cross-sectional area of ​​the lampshade is generally much larger than that of the lamp holder. The cap body is used as a transition between the connecting sleeve and the lampshade, and the appearance looks more beautiful.

[0016] By adopting the above technical solution, the utility model has the following beneficial effects:

[0017] (1) One end of the connecting sleeve is limited in the installation cavity enclosed by the installation sleeve and the sealing cover, and the connecting sleeve and the installation sleeve can rotate relative to each other. The lampshade is fixed on the installation sleeve.

[0018] (2) A first circumferential boss is provided on the outer wall of the connecting sleeve, and a second circumferential boss is provided on the inner wall of the mounting sleeve. The first circumferential boss is clamped by the second circumferential boss, and the end of the connecting sleeve is against the bottom wall of the sealing cover to achieve the connection and fixation between the connecting sleeve and the mounting sleeve. At the same time, the first circumferential boss and the second circumferential boss are not in a stuck state, but can rotate with each other, so as to achieve the purpose that the connecting sleeve and the mounting sleeve can rotate with each other;

In this solution, the lamp holder 1 and the connecting sleeve 2 are fixed and do not rotate, the mounting sleeve 3 and the sealing cover 4 are fixed and do not rotate, the mounting sleeve 3 and the connecting sleeve 2 are connected by a limiting device, and the two can rotate relative to each other, and the lampshade 8 is fixed on the mounting sleeve 3, so when the lampshade 8 needs to be rotated, it is only necessary to fix the connecting sleeve 2 and rotate the mounting sleeve 3, or fix the mounting sleeve 3 and rotate the connecting sleeve 2, so as to achieve the purpose of rotating the lampshade 8. Specifically, a circuit board 25 is installed in the connecting sleeve 2, a power line 27 is connected to the lamp head 1 and communicated with the circuit board 25, and the filament 26 in the lampshade 8 extends into the connecting sleeve 2 through the sealing cover 4 and the mounting sleeve 3, and is connected to the circuit board 25, completing the internal power connection of the lamp, and the filament 26 is lit. Since the filament 26 has a certain redundant length, when the lampshade 8 is rotated at a certain angle, the filament 26 will not be twisted and fall off the circuit board 25, which improves the applicability of the overall lamp when the lampshade 8 needs to be rotated.

That is to say, after the first circumferential boss 9 and the second circumferential boss 10 are clamped together, the second circumferential boss 10 limits the connection sleeve 2 from being taken out from the second end 6 of the mounting sleeve, and at the same time, the end of the connecting sleeve 2 abuts against the bottom wall of the sealing cover 4, so that the connection and fixation of the connecting sleeve 2 and the mounting sleeve 3 are realized.
