Description

Technical Field

[0001] This utility model belongs to the field of lighting design technology, and in particular relates to a rotating structure and a lighting fixture. Background Technology

[0002] Existing lamp housing rotation structures typically employ a dual-rotor design, where rotating shafts are symmetrically inserted on both sides of the lamp housing to achieve a rotatable connection between the upper and lower housings. However, this rotating shaft structure requires the insertion of rotating shafts on both the left and right sides and the fixing of the left and right rotating shafts separately, making the installation overly cumbersome. Utility Model Content

[0003] To address the aforementioned problems, this utility model provides a rotating structure for a lamp and a lamp equipped with the rotating structure, wherein the rotating structure of the lamp can be installed simply and quickly.

[0004] The technical solution of this utility model is as follows:

[0005] A rotating structure for a lamp includes:

[0006] The first housing has a first mounting part and a second mounting part. The first mounting part has a first insertion hole, and the second mounting part has a second insertion hole. The first insertion hole is arranged along the rotation axis, and the first mounting part and the second mounting part are spaced apart in the direction along the rotation axis.

[0007] A rotating component includes a middle portion and a first insertion portion and a second insertion portion respectively disposed at both ends of the middle portion. The first insertion portion is inserted into the first insertion hole and rotatably connected thereto. A boss is provided on the inner sidewall of the second insertion hole, and a rotating hole is formed on the inner sidewall of the boss. The rotating hole is disposed along the rotation axis. The second insertion portion is inserted into the second insertion hole and rotatably connected to the rotating hole.

[0008] A second shell is provided, and a fixing structure is provided between the second shell and the rotating member. The fixing structure is used to fix the middle part to the second shell.

[0009] In an optional embodiment, the boss is provided on the inner sidewall of the second socket near the end of the first mounting portion.

[0010] In an optional embodiment, the centerline of the second socket is parallel to or coincides with the axis of rotation.

[0011] In an optional embodiment, the first insertion portion and the second insertion portion are disposed along the rotation axis, and the intermediate portion at least partially protrudes in the radial direction relative to the first insertion portion and the second insertion portion relative to the rotation axis.

[0012] In an optional embodiment, the rotating member is formed by bending a rod, the two ends of which are the first insertion portion and the second insertion portion, respectively, and the middle portion is bent multiple times so that the middle portion at least partially protrudes in the radial direction relative to the first insertion portion and the second insertion portion relative to the rotation axis.

[0013] In an optional embodiment, the fixing structure includes a limiting part and a pressing part, the limiting part being used to restrict the movement of the rotating member along the direction of the rotation axis, and the pressing part being used to press the intermediate part against the second shell.

[0014] In an optional embodiment, the limiting part is a receiving groove disposed on the second shell. The receiving groove has a first limiting surface and a second limiting surface that respectively abut against the intermediate part. The first limiting surface is used to limit the rotation member from moving along the rotation axis toward the first mounting part, and the second limiting surface is used to limit the rotation member from moving along the rotation axis toward the second mounting part.

[0015] In an optional embodiment, the clamping portion includes at least one clamping member threadedly connected to the second housing, the clamping member having a clamping surface that abuts against the intermediate portion to clamp the intermediate portion onto the second housing.

[0016] In an optional embodiment, the length of the first insertion portion is less than the length of the second insertion portion in the direction along the rotation axis.

[0017] Based on the same concept, this utility model also provides a lamp, including the rotating structure of any of the lamps described above.

[0018] Because of the adoption of the above technical solution, this utility model has the following advantages and positive effects compared with the prior art:

[0019] The rotating structure of the lamp provided by this utility model features a second insertion part that is rotatably connected to a rotating hole formed by a boss in the second socket. The rotating boss protrudes from the inner wall of the second socket, allowing the second insertion part to be inserted at an angle relative to the rotation axis. This enables the first insertion part to reach the end face of the first mounting part (i.e., the end face of the first mounting part facing the second mounting part, where the first socket is located), thus smoothly entering the first socket. When the first insertion part aligns with the first socket, the second insertion part returns to its original position within the rotating hole. After the first insertion part is inserted into the first socket, the first socket and the rotating hole cooperate, ensuring that the first insertion part can only connect to the first socket along the rotation axis, and the second insertion part can only connect to the rotating hole along the rotation axis, thereby connecting the rotating component to the first shell. Then, the middle part of the rotating component is fixed to the second shell via a fixing structure, thus connecting the rotating component to the second shell and completing the installation of the entire rotating structure of the lamp. The rotating structure of the lamp provided by this utility model offers a simple and convenient installation process, effectively solving the problem of cumbersome installation caused by the dual-rotating-component design in existing technologies.

Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

Furthermore, for ease of understanding, in some figures, only one of the components with the same structure or function is schematically depicted, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one."

[0031] Example 1

[0032] See Figures 1 to 8 This embodiment provides a rotating structure for a lamp, including a first housing 1, a second housing 2, and a rotating component 3. The first housing 1 has a first mounting portion 4 and a second mounting portion 5. The first mounting portion 4 has a first insertion hole 6, and the second mounting portion 5 has a second insertion hole 7. The first insertion hole 6 is arranged along the rotation axis, and the first mounting portion 4 and the second mounting portion 5 are spaced apart along the rotation axis. The rotating component 3 includes a middle portion 11 and a first insertion portion 9 and a second insertion portion 10 respectively located at both ends of the middle portion 11. The first insertion portion 9 is inserted into and rotatably connected to the first insertion hole 6. A boss protrudes from the inner sidewall of the second insertion hole 7, and the inner sidewall of the boss forms a rotating hole 8. The rotating hole 8 is arranged along the rotation axis, and the second insertion portion 10 is inserted into the second insertion hole 7 and rotatably connected to the rotating hole 8. A fixing structure is provided between the second housing 2 and the rotating component 3 to fix the middle portion 11 to the second housing 2.

[0033] Since the second insertion part 10 is rotatably connected to the rotating hole 8 formed by the boss in the second socket 7, and the rotating boss protrudes from the inner wall of the second socket 7, the second insertion part 10 can be inserted at an angle relative to the rotation axis when inserted into the rotating hole 8. This allows the first insertion part 9 to reach the end face of the first mounting part 4 (i.e., the end face of the first mounting part 4 facing the second mounting part 5, on which the first socket 6 is opened), and thus smoothly enter the first socket 6. When the first insertion part 9 is aligned with the first socket 6, the second insertion part 10 returns to its original position in the rotating hole 8. After the first insertion part 9 is inserted into the first socket 6, the first socket 6 and the rotating hole 8 cooperate with each other so that the first insertion part 9 can only be connected to the first socket 6 along the rotation axis, and the second insertion part 10 can only be connected to the rotating hole 8 along the rotation axis, thereby realizing the connection between the rotating part 3 and the first shell 1. Then, the middle part 11 of the rotating part 3 is fixed to the second shell 2 through a fixing structure, thereby realizing the connection between the rotating part 3 and the second shell 2, and completing the installation of the rotating structure of the entire lamp. The rotating structure of the lamp provided in this embodiment makes the entire installation process simple and convenient, effectively solving the problem of complicated installation caused by the use of a dual rotating part 3-rotation design in the prior art.

[0034] The rotating structure of the lamp in this embodiment will be further described below. It should be noted that, unless otherwise specified, this description is based on the state of the lamp after its rotating structure is installed. All rotation axes mentioned herein refer to the same axis.

[0035] like Figure 7 and Figure 8 As shown, the boss is located on the inner wall of the second insertion hole 7 near the end of the first mounting portion 4. This location, compared to other positions on the inner wall of the first mounting portion 4, allows the second insertion portion 10 to achieve a larger maximum tilt angle relative to the rotation axis when inside the rotation hole 8. Furthermore, to maximize the maximum tilt angle of the second insertion portion 10 relative to the rotation axis when inside the rotation hole 8, thereby facilitating the first insertion portion 9 reaching the end face of the first mounting portion 4 (i.e., the end face where the first insertion hole 6 is located), the length of the boss along the rotation axis needs to be shorter.

[0036] Preferably, the second insertion hole 7 is a circular hole and is positioned along the rotation axis; thus, within a 360-degree circumference around the rotation axis, the second insertion part 10 can achieve the maximum tilt angle regardless of which direction it is tilted into the rotating hole 8, thereby facilitating installation. Of course, when space is limited, the second insertion hole 7 can be designed as an oblong hole, such as... Figure 7 As shown, the center line of the second socket 7 is parallel to or coincides with the axis of rotation.

[0037] Preferably, the first insertion portion 9 and the second insertion portion 10 are arranged along the rotation axis, and the middle portion 11 protrudes at least partially relative to the first insertion portion 9 and the second insertion portion 10 in the radial direction of the rotation axis. Specifically, in this embodiment, the rotating member 3 is formed by bending a rod, with the two ends of the rod being the first insertion portion 9 and the second insertion portion 10, respectively. The middle portion 11 is bent multiple times so that the middle portion 11 protrudes at least partially relative to the first insertion portion 9 and the second insertion portion 10 in the radial direction of the rotation axis. More specifically, the intermediate portion 11 includes a parallel segment 12 and two vertical segments 13. The centerline of the parallel segment 12 is parallel to the rotation axis, and the centerline of the vertical segments 13 is perpendicular to the rotation axis, with the two vertical segments 13 located on the same side of the rotation axis. The two vertical segments 13 are respectively connected to the two ends of the parallel segment 12 and are respectively connected to the two ends of the parallel segment 12 in an arc shape. One end of one vertical segment 13 that is not connected to the parallel segment 12 is connected to the end of the first insertion portion 9 facing the second insertion portion 10, and the two are connected in an arc shape. The other end of the vertical segment 13 that is not connected to the parallel segment 12 is connected to the end of the second insertion portion 10 facing the first insertion portion 9, and the two are connected in an arc shape.

[0038] The design of the middle part 11 protruding radially towards the rotation axis relative to the first insertion part 9 and the second insertion part 10 allows the fixing structure to move radially outward from the rotation axis, i.e., into the cavity formed by the cooperation of the first shell 1 and the second shell 2 (relative to the fact that the rotating part 3 is a straight strip). This makes it less likely for the fixing structure to affect the relative rotation of the first shell 1 and the second shell 2. For example, as mentioned below, the fixing structure in this embodiment has a screw 17. The height of the internal space of the cavity formed by the cooperation of the first shell 1 and the second shell 2 is greater than the height of the rotational connection point of the first shell 1 and the second shell 2 (i.e., at the rotation axis), making it easier and more convenient to install the screw 17.

[0039] Furthermore, in the direction along the rotation axis, the length of the first insertion portion 9 is less than the length of the second insertion portion 10. In the direction of the rotation axis, the distance between the end of the first insertion hole 6 away from the second insertion hole 7 and the end of the second insertion hole 7 away from the first insertion hole 6 (referred to as the first distance for ease of description) is limited by the dimensions of the first housing 1 and the second housing 2 themselves; while in the direction of the rotation axis, the length of the rotating member 3 is less than the first distance. With the length of the rotating member 3 fixed, the design that the length of the first insertion portion 9 is less than the length of the second insertion portion 10 is more conducive to the first insertion portion 9 reaching the end face of the first mounting portion 4 (i.e., the end face where the first insertion hole 6 is located).

[0040] The fixing structure includes a limiting part and a pressing part. The limiting part is used to restrict the movement of the rotating member 3 along the direction of the rotation axis, and the pressing part is used to press the intermediate part 11 onto the second shell 2.

[0041] Specifically, the limiting part is a receiving groove 14 provided on the second shell 2. The receiving groove 14 has a first limiting surface 15 and a second limiting surface 16 that respectively abut against the intermediate part 11. The first limiting surface 15 is used to limit the movement of the rotating member 3 along the rotation axis towards the first mounting part 4, and the second limiting surface 16 is used to limit the movement of the rotating member 3 along the rotation axis towards the second mounting part 5. Therefore, the first limiting surface 15 and the second limiting surface 16 cooperate to fix the position of the rotating member 3 in the direction along the rotation axis. Preferably, the shape of the receiving groove 14 is adapted to the intermediate part 11; the receiving groove 14 has a portion for accommodating the parallel section 12 and a portion for accommodating the vertical section 13, wherein the first limiting surface 15 and the second limiting surface 16 are respectively provided in the portion of the density groove for accommodating the vertical section 13.

[0042] The clamping part includes at least one clamping member, which is threadedly connected to the second shell 2. The clamping member has a clamping surface that abuts against the intermediate part 11 to press the intermediate part 11 onto the second shell 2. In this embodiment, the clamping part includes three clamping members, which correspond to the parallel segment 12 and the two vertical segments 13 of the intermediate part 11, respectively, and press the parallel segment 12 and the two vertical segments 13 onto the second shell 2. Further, in this embodiment, the clamping member can be a screw 17, and the nut of the screw 17 presses the intermediate part 11 onto the second shell 2. Of course, in other embodiments, the fixing structure can also adopt other structural forms, and the specific structure of the fixing structure is not limited.

[0043] During installation, first insert the second insertion part 10 into the rotating hole 8, tilting it relative to the rotation axis so that the first insertion part 9 can reach the end face of the first mounting part 4 (i.e., the end face with the first insertion hole 6). Then, drive the first insertion part 9 (actually, hold the middle part 11 to drive the rotating part 3) in a direction that aligns its center line with the rotation axis, until the first insertion part 9 rotates to face the first insertion hole 6. At this point, the center lines of the first insertion part 9 and the second insertion part 10 are both aligned with the rotation axis. Then, insert the first insertion part 9 into the first insertion hole 6, completing the installation of the rotating part 3 and the first shell 1. Afterward, rotate the rotating part 3 so that the middle part 11 is accommodated in the receiving groove 14 of the second shell 2. Then, fix the screw 17 to secure the middle part 11 to the second shell 2, completing the installation of the rotating part 3 and the second shell 2, thus completing the installation of the rotating structure of the entire lamp in this embodiment. It should be noted that the above installation scheme is only an example and not a limitation of this utility model. Adjustments can be made according to specific circumstances in actual situations.
