[0002] Lamps can be divided into chandeliers, ceiling lamps, wall lamps, spotlights, etc. In order to enable the lamp body to be installed in different positions, a lamp adapter was born.

[0003] Existing lamp adapters are fixed in size and shape, and can generally only be used to connect the power supply to a single angle. For example, after the power supply port on the wall is connected through a 90-degree adapter, the light source of the lamp can be facing downward to form a wall lamp. However, due to the diversity of lamp designs, an adapter of a single shape cannot be rotated after being plugged into a socket, so it cannot meet the needs of a variety of lamp bodies. As a result, users need to purchase adapters of multiple different angles to meet installation requirements. This is quite inconvenient and urgently needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0024] The scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model. In addition, the descriptions of "first", "second", etc. in the utility model are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features.

[0025] In view of the technical defects existing in the related art, the utility model provides a multi-angle rotating adapter, which is applied to lamps. Figures 1 to 3 The multi-angle rotating adapter includes: a fixed tube 100, an adapter seat 200, a rotating joint 300, a limiter 400 and a lamp holder 500; the fixed tube 100 is arranged in a cylindrical structure. At this time, the shape of the fixed tube 100 can be a cylindrical shape, a square cylindrical shape, or other polygonal cylindrical shapes. In order to facilitate the multi-angle rotating adapter to be arranged as a rotatable adapter and the overall appearance of the adapter is simple, in this embodiment, the fixed tube 100 is arranged in a cylindrical shape.

[0026] The adapter 200 is detachably mounted on one end of the fixed tube 100, and the adapter 200 is used to electrically connect to an external power socket; at this time, the adapter 200 is connected to the fixed tube 100 in a detachable manner, which may be a snap connection, a screw lock, etc.

[0027] The rotating joint 300 is rotatably connected to the other end of the fixed tube 100, and the rotating joint 300 is at least partially located in the fixed tube 100; that is, one end of the fixed tube 100 is sleeved on the rotating joint 300, and the rotating joint 300 is partially in the fixed tube 100, and the rotating joint 300 rotates relative to the fixed tube 100.

[0028] Furthermore, the limit member 400 is connected to one end of the rotating joint 300 located in the fixed tube 100. At this time, there are multiple ways to connect the limit member 400 and the rotating joint 300. The limit member 400 can be connected to the rotating joint 300 in a detachable connection manner, such as screw locking, snap connection, etc.; the limit member 400 can also be connected to the rotating joint 300 in a non-detachable connection manner, such as welding, bonding, etc. The specific connection method between the limit member 400 and the rotating joint 300 is not specifically limited here.

[0029] The stopper 400 is used to limit the rotation angle of the rotating joint 300. In addition, the lamp holder 500 is detachably connected to the end of the rotating joint 300 away from the fixing tube 100, and the lamp holder 500 is also electrically connected to the adapter 200. In this way, the multi-angle rotating adapter can be rotated to different angles to meet the illumination angles of different lamp installations.

[0030] In addition, the stopper 400 can be specifically used to rotate the rotating joint 300 in a variety of ways. For example, the outer peripheral wall of the stopper 400 is provided with two first convex ribs, and the inner wall of the fixed tube 100 is provided with a second convex rib, and the second convex rib is located between the two first convex ribs. In this way, when the stopper 400 rotates with the rotating joint 300, the side walls of the two first convex ribs will abut against the side walls of the second convex rib to limit the rotation angle of the rotating joint 300.

[0031] For another example, the outer wall of the limit member 400 is provided with a groove 300b extending along its circumferential direction, and the interior of the fixed tube 100 is provided with a limit block, which is located in the groove 300b. In this way, when the limit member 400 rotates with the rotating joint 300, the side wall of the limit block will abut against the inner wall of the groove 300b to limit the rotation angle of the rotating joint 300. There are many other ways to set the rotation angle of the limit member 400 to rotate the rotating joint 300, which will not be described one by one here.

[0032] In this example, see Figure 3 and Figure 4The inner circumferential wall of the fixing tube 100 is provided with a positioning rib 110, and the outer circumferential wall of the limiting member 400 is provided with two limiting bosses 410, which are arranged at an angle of 90 degrees along the outer circumferential wall of the limiting member 400, and the positioning rib 110 is located between the two limiting bosses 410. Such an arrangement facilitates the limiting member 400 to limit the rotation of the rotating joint 300, and also prevents the electric cable electrically connected between the lamp holder 500 and the adapter 200 from being entangled and twisted due to the rotation angle.

[0033] In some embodiments, there are two positioning ribs 110, and the two positioning ribs 110 are arranged at 180 degrees along the inner circumferential wall of the fixed tube 100. There are four limiting bosses 410 protruding from the outer circumferential wall of the limiting member 400, and each limiting boss 410 is arranged at 90 degrees along the outer circumferential wall of the limiting member 400, and the two positioning ribs are respectively located between the two corresponding limiting bosses 410. In this arrangement, compared with only the positioning ribs 110 protruding from the inner circumferential wall of the fixed tube 100, when installing the limiting member 400, it is not necessary to observe whether the positioning rib 110 is located between the two limiting bosses 410, because there are four limiting bosses 410 and they are arranged at 90 degrees on the outer circumferential wall of the limiting member 400. However, no matter where the limiting member 400 is installed, the positioning rib 110 is located between two adjacent limiting members 400 arranged at 90 degrees, which facilitates the installation of the limiting member 400.

[0034] To facilitate the installation of the stopper 400 on the rotary joint 300, please continue to refer to Figure 3 and Figure 4 In this embodiment, the limit member 400 is sleeved on the rotating joint 300, the inner wall of the limit member 400 is convexly provided with a protrusion 420, and the outer wall of the rotating joint 300 is concavely provided with a groove 300a corresponding to the protrusion 420; a snap-on connection method is adopted to facilitate the installation of the limit member 400 on the rotating joint 300.

[0035] See also Figure 1 and Figure 2 In order to make the rotating joint 300 have a damping feeling when rotating, in some embodiments, the multi-angle rotating adapter further includes a silicone block 600, which is installed on the outer peripheral wall of the rotating joint 300 and abuts against the fixed tube 100. The silicone block 600 and the fixed tube 100 form damping through friction, so that the rotating joint 300 can stop rotating at a fixed point after rotating.

[0036] It should be noted that there are various ways to install the silicone block 600 on the rotating joint 300. The silicone block 600 can exist alone and be installed on the rotating joint 300 by a detachable connection method such as snap-on, screw locking, etc. The silicone block 600 can also be installed on the rotating joint 300 by a non-detachable connection method such as bonding, ultrasonic welding, etc. The silicone block 600 can also be directly integrally formed with the rotating joint 300 by secondary injection molding. The specific installation method used for installing the silicone block 600 on the rotating joint 300 is not limited here.

[0037] In this embodiment, the outer peripheral wall of the rotating joint 300 is provided with a groove 300b, and the groove 300b is at least partially located inside the fixed tube 100. The silicone block 600 is installed in the groove 300b, and the silicone block 600 partially extends out of the groove 300b and abuts against the inner peripheral wall of the fixed tube 100. At this time, the silicone block 600 can be fixed in the groove 300b by plugging or clamping, which is also convenient for subsequent replacement and maintenance of the silicone block 600.

[0038] To prevent the rotating joint 300 from being separated from the fixed tube 100 , in some embodiments, an annular boss 120 is provided on one end of the inner wall of the fixed tube 100 away from the adapter 200 , and the limiting member 400 at least partially abuts against the annular boss 120 .

[0039] In this embodiment, the rotating joint 300 has a rotating section 310 and a mounting section 320 that protrudes vertically and laterally from the rotating section 310. The mounting section 320 and the rotating section 310 are both cylindrical structures and are internally connected to each other. One end of the rotating section 310 away from the mounting section 320 is rotatably connected to the fixed tube 100, and one end of the mounting section 320 away from the rotating section 310 is detachably connected to the lamp holder 500. Specifically, the lamp holder 500 is mounted on the end surface of the mounting section 320 by screw locking.

[0040] The utility model also provides a lamp, see Figure 5 The lamp includes a lamp body 700 and the above multi-angle rotating adapter, and the lamp body 700 is connected to the lamp holder 500. It should be noted that the specific structure of the multi-angle rotating adapter refers to the above embodiment, and since the lamp adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be repeated here.

[0041] The above description is only a partial or preferred embodiment of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
