Description

Technical Field

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

[0002] In the urban lighting system, street lamps are an important part of the infrastructure, and their design and performance directly affect the safety and beauty of public spaces. The structure of traditional street lamps is mostly composed of an upper cover, a lamp housing, and an electrical cavity located between the two. This design facilitates the installation, maintenance and replacement of electrical components, thereby ensuring the normal operation and long-term maintenance of street lamps. In order to achieve flexible rotation between the upper cover and the lamp housing, so as to facilitate the convenient operation of the components in the electrical cavity, a connection method based on the matching of protrusions and grooves, supplemented by a rotating shaft, is generally used in the prior art.

[0003] However, while this traditional rotating connection structure brings convenience, it also exposes a series of problems. Specifically, the structure requires a protrusion to be set on a certain part of the upper cover or lamp housing, and a matching groove is designed on the corresponding part so that the protrusion can be smoothly inserted and fixed. Subsequently, the rotating shaft is inserted into the contact surface of the protrusion and the groove to achieve a rotating connection between the two. Although this design meets the functional requirements, it inevitably causes defects in the appearance of the street lamp.

[0004] First, due to the presence of protrusions and grooves, as well as the assembly requirements of the rotating shaft, the surface of the street lamp forms relatively obvious pits or protrusions at the joints, which destroys the overall streamlined design and flatness of the street lamp. This not only affects the aesthetics of the street lamp, but may also accelerate the aging of the street lamp due to dust and water accumulation, reducing its service life. Secondly, from a visual point of view, the two obvious rotating structures on the lamp appear abrupt and difficult to blend harmoniously with the surrounding environment, affecting the coordination and aesthetics of the urban landscape. In today's pursuit of urban beautification and refined management, such a design obviously can no longer meet market demand. Utility Model Content

It should be noted that the accompanying drawings are all in a very simplified form and use non-precise ratios, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the utility model.

[0041] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0042] Example 1

[0043] See also Figures 1 to 6 The core of the utility model is to provide a rotation connection structure for rotationally connecting the cover body 1 to the shell body 3, including a limit member 2, a first groove 23, a second groove 32 and a rotating shaft 11.

[0044] The stopper 2 is fixed to the housing 3 by a fastener. The stopper 2 is provided with a fastener on the side away from the housing 3. The stopper 2 is fixed to the housing 3 by the fastener. In this embodiment, the fastener is a screw 4. Of course, in other embodiments, the fastener may also be other components, which is not limited in this embodiment. The first groove 23 is provided on the stopper 2 and is located on the side of the stopper 2 facing the housing 3. The second groove 32 is provided on the housing 3 and is located on the side of the housing 3 facing the stopper 2. The first groove 23 and the second groove 32 are arranged oppositely and the two are combined to form a slot 5. The shaft 11 is provided on the cover 1. The shaft 11 is inserted and rotatably connected in the slot 5 so that the cover 1 can rotate around the housing 3.

[0045] In order to prevent the screw 4 from interfering with other components, a boss 31 is provided on the housing 3 , the limiting member 2 is mounted on the boss 31 by means of the screw 4 , and at the same time, a second groove 32 is also formed on the boss 31 .

[0046] The utility model is provided with a first groove 23 and a second groove 32 on the stopper 2 and the shell 3, respectively. The first groove 23 and the second groove 32 are combined into a slot 5. The shaft 11 is inserted and rotatably connected in the slot 5, so that the structure does not need to punch holes horizontally on the shell 3 during assembly. It only needs to vertically drive the screws 4 to fix the stopper 2 during assembly, which is more convenient to assemble. If a flip structure similar to the upper cover of the earphone box is adopted, that is, a protrusion is provided on the upper cover, and the lamp shell is provided in a groove matching the protrusion, and after the protrusion is inserted into the groove, a shaft 11 is passed through the lamp shell to realize rotational connection with the protrusion, then the structure needs to punch holes horizontally on the lamp shell, which is cumbersome to process, and the shaft 11 needs to be inserted horizontally during assembly, which is easily interfered by the side wall of the lamp shell, and the assembly is relatively difficult.

[0047] The first groove 23 is provided on the stopper 2, and the second groove 32 is provided on the shell 3. If only the shell 3 is provided with a groove, then in order to accommodate the shaft 11, the groove depth of the second groove 32 must be relatively deep, and the thickness of the shell 3, the height of the boss 31 and the internal space of the shell 3 are relatively high. If there is no first groove 23, but the shaft 11 is placed in the second groove 32, then the interference range when the cover 1 rotates is large, and it is easy to interfere with other parts. If only the first groove 23 is designed, when the shaft 11 is placed on the boss 31 and then covered with the stopper 2, the shaft 11 cannot be pre-fixed and is easy to deviate. In addition, in order to meet the depth requirement of the first groove 23, the height of the stopper 2 at this location will be relatively high, and it is difficult to keep it flush with the surface of the cover 1.

[0048] Furthermore, a rotating shaft 11 is respectively provided on both sides of the cover body 1, a first groove 23 is respectively provided on both sides of the stopper 2, and a second groove 32 is respectively provided on both sides of the housing 3. The two first grooves 23 and the two second grooves 32 respectively form two slots 5, and the two rotating shafts 11 are respectively inserted and rotatably connected in the two slots 5. In this embodiment, the two first grooves 23 are formed in one piece, that is, the two first grooves 23 are composed of one groove.

[0049] Furthermore, the cover body 1 is provided with a first avoidance groove 12 at one end facing the limiter 2, and the first avoidance groove 12 is open at one end facing the limiter 2, and two rotating shafts 11 are respectively provided on the groove walls on both sides of the first avoidance groove 12. The limiter 2 includes a connecting portion 22 and a covering portion 21, the connecting portion 22 is fixedly connected to the boss 31 on the housing 3 by screws 4, the first groove 23 is provided on the side of the covering portion 21 facing the housing 3, and the connecting portion 22 extends into the side of the cover body 1 facing the housing 3 through the first avoidance groove 12, so that the connecting portion 22 can be shielded after the cover body 1 is covered, and the screws 4 and other components of the connecting portion 22 cannot be seen from the outside of the lamp, which is more beautiful.

[0050] Preferably, the covering portion 21 is arranged to protrude away from the shell body 3, that is, the top of the connecting portion 22 in the height direction of the limiting member 2 itself is lower than the top of the covering portion 21, and the covering portion 21 is flush with the structural extension direction of the cover body 1, and at least part of the covering portion 21 is arranged in the first avoidance groove 12, so that the surface of the cover body 1 can smoothly transition with the upper surface of the covering portion 21 exposed by the limiting member 2, and the entire upper surface of the lamp is smooth and beautiful without any large pits.

[0051] A second avoidance groove 33 is provided on the shell 3, part of the covering part 21 is provided in the first avoidance groove 12, and the other part of the covering part 21 is provided in the second avoidance groove 33. By providing the second avoidance groove 33, on the one hand, the covering part 21 will not protrude from the shell 3, and on the other hand, the material used for the shell 3 can be reduced, thereby reducing the cost.

[0052] Furthermore, the cover body 1 is tilted toward the shell 3 at least at one end facing the limit member 2, so that the two ends of the first avoidance groove 12 have a height difference in the direction toward the shell 3, so as to facilitate the insertion of the connecting portion 22 of the limit member 2 under the cover body 1 through the first avoidance groove 12, and the covering portion 21 is tilted away from the connecting portion 22 and toward the shell 3 along the tilt direction of the cover body 1, so that the overall appearance is more beautiful and the surface is overall flat.

[0053] The covering portion 21 has a marking area extending in a direction away from the connecting portion 22, and a logo can be printed on the marking area. The covering portion 21 is tilted away from the connecting portion 22 and toward the shell 3 along the tilt direction of the cover body 1, which can increase the upper surface area of ​​the covering portion 21 to facilitate printing of the logo.

[0054] A gap is provided between the covering portion 21 and the groove wall of the first avoidance groove 12 away from the open end thereof to prevent interference.

[0055] Specifically, a chamfer is provided on the corner of the covering portion 21 facing one end of the first avoidance groove 12, and a slope 24 is formed on the chamfer. When the cover body 1 is closed, the slope 24 is arranged parallel to the groove wall of the first avoidance groove 12 away from its open end, and a gap is arranged between the slope 24 and the groove wall of the first avoidance groove 12 away from its open end.

[0056] If the inclined surface 24 is not provided, the cover body 1 will easily interfere with the stopper 2 when rotating. If the volume of the stopper 2 is reduced or the distance between the stopper 2 and the cover body 1 is increased, the gap between the cover body 1 and the stopper 2 will appear very large after the cover is closed, which is very unsightly, and the horizontal distance between the shaft 11 and the screw 4 will become longer, and the fixing effect of the screw 4 on the stopper 2 and the shaft 11 will become worse. By providing the inclined surface 24 at the top edge of the inner wall opposite to the first avoidance groove 12 of the cover part 21, on the one hand, the cover body 1 is prevented from interfering with the stopper 2 when rotating, and on the other hand, when the cover body 1 is in the closed state, the gap between the cover body 1 and the stopper 2 is also very small.

[0057] In addition, a limiting protrusion 34 is provided in the first groove 23 and / or the second groove 32, and the limiting protrusion 34 is used to limit the rotation shaft 11. When the rotation shaft 11 is inserted into the slot 5 and abuts against the limiting protrusion 34, there is a gap between the groove walls on both sides of the first avoidance groove 12 and the limiting member 2 to prevent the groove walls on both sides of the first avoidance groove 12 from interfering with the limiting member 2 during rotation. In this embodiment, the limiting protrusion 34 is arranged in the second groove 32, and the second groove 32 is a blind groove, and the limiting protrusion 34 is composed of a structure on one side of the groove bottom of the second groove 32.
