DETAILED DESCRIPTION

[0027] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary and are intended to explain the present application, and cannot be understood as limiting the present application.

[0028] The present application relates to a kind of cylinder spotlight rotating structure, including base 100, cover 200 and lamp assembly 300.

[0029] As Figure 1 , Figure 2 , Figure 3 , Figure 4 And Figure 5As shown, the base 100 can be provided in a cylindrical shape or other shapes. The inside of the base 100 is hollow to form a cavity 110. In the shown direction, the base 100 is vertically placed, and the cavity 110 forms two ports through the upper and lower sides of the base 100. The inner wall of the cavity 110 is provided with a first limiting member 120 and a clamping groove 130. The first limiting member 120 can be integrally formed on the inner wall of the cavity 110 or be installed in the cavity 110 as an independent component. In the embodiment, the first limiting member 120 is in the form of a convex column extending out of the side wall of the cavity 110. The clamping groove 130 extends in the form of a circular ring on the inner wall of the cavity 110. The cover 200 is provided with a second limiting member 210 and a clamping head 220. A plurality of clamping heads 220 are distributed in sequence along a circumference on the same side of the cover 200. The second limiting member 210 can be installed on the cover 200 as an independent component or be integrally formed on the cover 200. In the embodiment, the second limiting member 210 is in the form of a convex column extending out of the cover 200. The cover 200 is in the form of a circular plate. The cavity 110 can be in the form of a cylinder extending through the base 100 in the axial direction. The two ports of the cavity 110 are in the form of circular openings. The shape of the cover 200 is adapted to the shape of the ports of the cavity 110, the cover 200 is covered at one of the ports of the cavity 110, and the clamping head 220 extends into the cavity 110 and is clamped on the clamping groove 130. Through the cooperation of the clamping groove 130 and the clamping head 220, the cover 200 can be prevented from being pulled out of the base 100, so that the cover 200 is quickly installed on the base 100; at the same time, the cover 200 can also rotate relative to the base 100 along the clamping groove 130. The second limiting member 210 rotates synchronously with the cover 200, and the first limiting member 120 is located on the movement path of the second limiting member 210. When the cover 200 rotates clockwise or counterclockwise to abut against the first limiting member 120 and the second limiting member 210, the cover 200 cannot continue to rotate, so as to limit the rotation of the cover 200 beyond 360° in the same direction. The lamp assembly 300 is connected to the side of the cover 200 away from the cavity 110, that is, the lamp assembly 300 is located outside the cavity 110. In actual assembly, the base 100 can be installed as a support on a wall, a ceiling or the like. Electrical devices such as power lines and circuit boards can be installed in the cavity 110. The power line passes through the cover 200 and is connected to the lamp assembly 300. In use, the lamp assembly 300 can rotate relative to the base 100 along with the cover 200 to change the illumination direction. The limiting action between the first limiting member 120 and the second limiting member 210 avoids the power line from being twisted. The overall structure of the cylindrical spotlight rotating structure is simple, and the installation and use are convenient.

[0030] In one embodiment, as Figure 5As shown, the cover 200 is provided with a first protruding rib 230, a second protruding rib 240 and a third protruding rib 250 on the side surface thereof facing the cavity 110. In the shown direction, the cover 200 is installed at the lower end of the cavity 110. The first protruding rib 230, the second protruding rib 240 and the third protruding rib 250 are arranged on the upper side surface of the cover 200. The first protruding rib 230 and the second protruding rib 240 extend circumferentially around the same center. The center can be the center of the cover 200. The second protruding rib 240 is closer to the center than the first protruding rib 230, i.e. the diameter of the circle on which the second protruding rib 240 is arranged is smaller than the diameter of the circle on which the first protruding rib 230 is arranged. The first protruding rib 230 is close to the periphery of the cover 200. There is a gap between the first protruding rib 230 and the second protruding rib 240 in the radial direction. The third protruding rib 250 is arranged at the gap between the first protruding rib 230 and the second protruding rib 240. A plurality of third protruding ribs 250 are distributed along the center in sequence. The third protruding rib 250 can be arranged in the shape of a long strip, one end of the third protruding rib 250 being connected to the first protruding rib 230 and the other end being connected to the second protruding rib 240. The arrangement of the first protruding rib 230, the second protruding rib 240 and the third protruding rib 250 can effectively increase the structural strength of the cover 200 in the circumferential direction when the cover 200 rotates relative to the base 100, thereby avoiding deformation of the periphery of the cover 200 and causing the clamping head 220 to disengage from the clamping groove 130.

[0031] Further, the cover 200 is also provided with a fourth protruding rib 260. The fourth protruding rib 260 is arranged on the same side surface of the cover 200 as the first protruding rib 230, the second protruding rib 240 and the third protruding rib 250. Three fourth protruding ribs 260 are arranged within the circular range formed by the second protruding rib 240, and the three fourth protruding ribs 260 are distributed in a triangular manner. Both ends of each fourth protruding rib 260 are connected to the second protruding rib 240. Adjacent ends of each fourth protruding rib 260 can be arranged in a spaced manner or connected to each other. The arrangement of the fourth protruding rib 260 can increase the structural strength of the middle part of the cover 200, and also avoid torsional deformation of the cover 200 and causing the clamping head 220 to disengage from the clamping groove 130. The positions at which the clamping heads 220 are distributed on the cover 200 are at the ends of the fourth protruding rib 260. That is, the clamping head 220 is located at the end angle of the triangular distribution formed by the fourth protruding rib 260, and the end angle of the triangular distribution formed by the fourth protruding rib 260 cooperates with the first protruding rib 230, the second protruding rib 240 and the third protruding rib 250 to form a very high structural strength, effectively ensuring that the local position of the cover 200 at which the clamping head 220 is located is not easily deformed, can bear a very high force, and ensures the stability of the clamping head 220 and the clamping groove 130.

[0032] Each of the fourth ribs 260 has one or two locking heads 220 positioned at the triangular end of its distribution. When two locking heads 220 are provided at the triangular end, there is a certain gap between the two locking heads 220. The cooperation of the two locking heads 220 further improves the connection stability between the cover 200 and the slot 130 at this position.

[0033] Based on the above embodiments, such as Figure 5 As shown, the latch 220 extends from the cover 200 in a plate shape. The latch 220 includes a first plate 221 and a second plate 222. The first plate 221 extends axially from the first rib 230 toward the cavity 110. In the illustrated direction, the first plate 221 extends upward from the first rib 230. The second plate 222 extends upward from the side of the first plate 221 away from the cover 200, and extends obliquely away from the center. The upper side of the second plate 222 is engaged in the latching groove 130. The latch 220 is formed on the first rib 230, which is not easily deformed, thereby ensuring the positional stability of the latch 220 on the cover 200. Simultaneously, the arrangement of the first and second plates allows the first plate to have a certain elastic swinging ability relative to the first protruding rib 230, making the process of the second plate being inserted into the slot 130 smoother. The tilted arrangement of the second plate, in cooperation with the first plate, ensures that the second plate maintains a force in the insertion direction towards the slot 130, guaranteeing the stability of the engagement between the second plate and the slot 130. Furthermore, a fifth protruding rib 270 is provided on the side of the first plate 221 facing the center. The fifth protruding rib 270 is formed on the third protruding rib 250. The fifth protruding rib 270 restricts the first plate from swinging towards the center, further ensuring that the second plate is engaged in the slot 130.

[0034] In some specific embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3 As shown, the connection between the lamp assembly 300 and the cover 200 is located between the adjacent ends of two of the fourth ribs 260. The cover 200 between the adjacent ends of the two fourth ribs 260 has high structural strength and can support the heavy lamp assembly 300 without deformation.

[0035] In some embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 3As shown, the cover 200 and the lamp assembly 300 are provided with a connecting piece 400. The connecting piece 400 comprises a first connecting arm 410 and a second connecting arm 420. The first connecting arm 410 is fixed on the cover 200 by means of screws or the like, and the second connecting arm 420 is fixed on the lamp assembly 300 by means of screws or the like. The first connecting arm 410 and the second connecting arm 420 can be hingedly connected by means of a rotating shaft or the like. The cover 200 and the first connecting arm 410 are provided with a threading hole 401. The power cord is led out from the cavity 110 to the outside of the cavity 110 through the threading hole 401, and then connected with the lamp assembly 300. The lamp assembly 300 is turned over relative to the cover 200 through the connecting piece 400, and cooperates with the rotation of the cover 200 to further increase the adjustable illumination range of the lamp assembly 300.
