Description

Technical Field

[0001] The present invention relates to the technical field of plant lighting, and in particular to a plant lighting device. Background Art

[0002] Light is one of the important factors affecting plant growth and development. Plant lamps are often used to adjust light and control plant growth patterns. Existing plant lamps mostly include a lamp body module and a driving power box for controlling the light emission of the lamp body module. The lamp body module is relatively large and cannot be folded, which affects the convenience and cost of transportation.

[0003] A patent document in China with application number 201921497325.X and announcement date 2020.7.14 discloses an LED plant growth lamp that is easy to package and disassemble; it includes a mounting frame, an LED lamp tube and a driving power supply, the mounting frame includes two I-shaped brackets and a rotating connector, the brackets are connected by a rotating connector, and one of the brackets can be rotated downward and folded to the bottom of the other bracket through the rotating connector, the bracket includes a vertical mounting frame and two horizontal mounting frames, the horizontal mounting frames are connected by a vertical mounting frame, the two ends of the LED lamp tube are respectively connected to the two horizontal mounting frames, the driving power supply is installed on the vertical mounting frame, and the driving power supply is electrically connected to the LED lamp tube.

[0004] However, the first rotating part and the second rotating part of the growth lamp are hingedly connected by a screw and a nut; it is only that the end face of the first rotating part fits with the end face of the second rotating part, and the screw and the nut connect the first rotating part and the second rotating part; in this way, the screw needs to withstand a large shear force and is easy to be damaged; at the same time, only the end faces of the first rotating part and the second rotating part that are close to each other are fit to achieve connection; when in use, friction is generated between the first rotating part and the second rotating part; the fit end faces will wear; when the fit end faces are worn, the first rotating part and the second rotating part become loose; which will cause the first rotating part and the second rotating part to be loose. The damping feeling between the moving parts is weakened; the user experience is poor, and the first rotating part and the second rotating part are respectively fixed vertically in the hollow bracket by screws, so that the strength of the connection between the bracket and the rotating part depends only on the strength of the screws. After long-term use, the connection between the bracket and the rotating part will be damaged when the horizontal plane is subjected to excessive force to both sides, making the connection between the bracket and the rotating part unreliable. At the same time, when installing and disassembling the rotating part and the bracket, it is necessary to align the corresponding screw holes on the bracket and the rotating part and then install the screws in the screw holes, which is prone to installation deviation, resulting in inconvenient installation. Summary of the invention

[0005] The present invention provides a plant lighting device which has stable connection, is not prone to loosening, and is easy to install.

[0006] To achieve the above-mentioned purpose, the technical scheme of the present invention is: a plant lighting device, comprising a rotating connection assembly and a rotating bracket; the rotating connection assembly comprises a rotating connection mechanism and a rotating abutment structure; the rotating abutment structure comprises a rotating device 1 and a rotating device 2; the rotating device 1 abuts against the rotating device 2 and is hinged with the rotating device 2; a lamp body is installed on the rotating bracket; the lamp body installed on one rotating bracket is used to rotate relative to the lamp body installed on the other rotating bracket; the rotating device 1 is connected to a rotating connection mechanism; the rotating device 2 is connected to another rotating connection mechanism; the rotating device 1 and the rotating device 2 are located between the two rotating connection mechanisms; the rotating connection mechanism is connected to the rotating bracket; the rotating bracket comprises a bracket body and a side cover detachably connected to the bracket body; a rotating mounting piece is provided at one end of the rotating connection mechanism away from the rotating device; a positioning cavity is formed with the side cover and the bracket body; the rotating mounting piece is accommodated in the rotating mounting piece; the rotating mounting piece is provided with a horizontal protrusion along the width direction; the rotating mounting piece is provided with a vertical protrusion along the height direction; the positioning cavity is provided with a groove 1 that cooperates with the horizontal protrusion; the positioning cavity is provided with a groove 2 that cooperates with the vertical protrusion;

[0007] The rotating device 1 comprises a rotating support 1; the rotating support 1 is provided with a rotating member 1 and a rotating member 2 protruding toward the rotating device 2; the protruding heights of the rotating member 1 and the rotating member 2 are higher than the outer height of the rotating support 1; the rotating device 2 comprises a rotating support 2; the rotating support 2 is provided with a rotating member 3 protruding toward the rotating device 1; a rotating groove 1 for accommodating the rotating member 3 is formed between the rotating member 1 and the rotating member 2; the rotating member 3 can be rotatably arranged in the rotating groove 1; a rotating groove 2 for accommodating the rotating member 1 is formed between the rotating support 2 and the rotating member 3; The rotating member 1 can be rotatably arranged in the rotating groove 2; the rotating member 3 is formed around the rotating groove 3 for accommodating the rotating member 2; the rotating member 2 can be rotatably arranged in the rotating groove 3; the inner wall surface of the rotating support 2 and the outer wall surface of the rotating member 1, the inner wall surface of the rotating member 1 and the outer wall surface of the rotating member 3, and the inner wall surface of the rotating member 3 and the outer wall surface of the rotating member 2 slide and rub; the rotating support 2 is provided with a rotating mounting hole 1 at one end away from the rotating support 1; the rotating member 3 is provided with a rotating mounting hole 2; the rotating fixing member passes through the rotating mounting hole 1 and is connected with the rotating mounting hole 2.

[0008] The above arrangement, through the cooperation between the horizontal protrusion and the vertical protrusion and the groove one and the groove two, the rotating bracket can fix the rotating mounting member in the horizontal direction and the vertical direction; while the strength of the rotating mounting member is enhanced by the horizontal protrusion and the vertical protrusion, the reliability of the connection between the rotating mounting member and the rotating bracket is also enhanced; and the rotating connection assembly is detachably connected to the rotating connection mechanism through the side cover and the rotating bracket, which is convenient for installation and disassembly;

[0009] By cooperating the rotating groove 1 with the rotating member 3, the rotating groove 2 with the rotating member 1, and the rotating groove 3 with the rotating member 2, the shear force on the rotating assembly is dispersed, thereby reducing the shear force on the rotating fixed member. At the same time, due to the staggered arrangement of the rotating member 1, the rotating member 3 and the rotating member 2, the outer wall surface of the rotating member 3 slides and rubs with the inner wall surface of the rotating member 1, and the inner wall surface of the rotating member 3 slides and rubs with the outer wall surface of the rotating member 2. The contact area between the rotating device 1 and the rotating device 2 is increased, and the friction between the rotating device 1 and the rotating device 2 is increased. The situation that the damping sense is weakened due to the wear of one of the contact surfaces of the rotating device 1 and the rotating device 2 is avoided. By cooperating the rotating member with the rotating groove, the different wall surfaces of the rotating device 1 cooperate with the different wall surfaces of the rotating device 2, and the pressure of the different wall surfaces supporting the rotating connection assembly is reduced, so that the wear degree of each wall surface is reduced, and the service life is extended. At the same time, the position of the rotating mounting hole 1 and the rotating mounting hole 2 is associated with the rotating member and the rotating groove. When the rotating member cooperates with the rotating groove, the rotating mounting hole 1 will be aligned with the rotating mounting hole 2, which is convenient for installation and will not cause installation deviation.

[0010] Furthermore, the rotating fixing member is a reverse screw used to enable the rotating device 1 and the rotating device 2 to rotate only toward the back side of the lamp body.

[0011] Furthermore, the rotating connection mechanism includes a rotating connection member; the rotating connection member is connected to the upper end, the lower end and a side surface of the rotating support one; the rotating connection member is connected to the upper end, the lower end and a side surface of the rotating support two.

[0012] The above arrangement, because it is connected to the upper end, the lower end and one side of the rotating support, makes the rotating connecting member connected to one side of the rotating support as a whole, thereby increasing the connection strength between the rotating support one, the rotating support two and the rotating connecting member, and the connection is stable. It can also provide more abutment surfaces after the rotating support one and the rotating support two are connected, and further enhance the reliability of the connection.

[0013] Furthermore, the rotating connector mechanism also includes a rotating fastener; the rotating fastener is located between the rotating connector and the rotating mounting member; and is connected to the rotating connector and the rotating mounting member; an avoidance space is formed between the rotating fastener and the rotating device one, and between the rotating fastener and the rotating device two; and the rotating fastener is provided with reinforcing ribs.

[0014] In the above arrangement, by providing an avoidance space, the rotating fastener hinders the rotation of the rotating device 1 relative to the rotating device 2; and by providing reinforcing ribs, the supporting strength of the rotating connection assembly is improved.

[0015] Furthermore, the vertical protrusion is formed by protruding upward and downward from the height direction of the rotating mounting part; the upper end and the lower end of the bracket body are both provided with two grooves that cooperate with the vertical protrusion; the side cover is located on one side of the bracket body; the horizontal protrusion is formed by protruding toward the side cover from the width direction of the rotating mounting part; the side cover is provided with a groove one formed between the bracket bodies and cooperate with the horizontal protrusion; the vertical protrusion abuts against the upper end and the lower end of the bracket body; the horizontal protrusion abuts against the side cover.

[0016] With the above arrangement, the rotating mounting member is provided with vertical protrusions upward and downward from the height direction, so as to further enhance the strength of the rotating mounting member; at the same time, the vertical protrusions abut against the bracket body; the horizontal protrusions abut against the side cover; so as to further enhance the connection strength between the rotating mounting member and the rotating bracket.

[0017] Furthermore, a positioning structure 1 is provided on the side of the bracket body close to the side cover; a positioning structure 2 is extended toward the side cover from the positioning structure 1; a positioning structure 3 is convexly provided on the positioning structure 2; a positioning groove 1 is formed between the positioning structure 3 and the upper end of the bracket body and the lower end of the bracket body; a cover plate mounting member 1 is extended toward the positioning groove 1 from the side cover; the cover plate mounting member 1 is slidably arranged in the positioning groove 1; a limiting fixing member is connected between the side cover and the horizontal protrusion, and the limiting fixing member is used to fix the rotating mounting member and to limit the movement of the side cover.

[0018] The above arrangement, through the cooperation between the cover plate mounting piece and the positioning groove, enables the side cover to be quickly mounted on the bracket body, and is connected to the side cover and the rotating mounting piece through the limiting fixing piece, so that the side cover is fixed on the rotating bracket and the rotating mounting piece is fixed in the rotating bracket. At the same time, because the vertical protrusion abuts against the bracket body and the horizontal protrusion abuts against the side cover, it is avoided that the force between the rotating mounting piece and the rotating bracket is concentrated on the limiting fixing piece.

The lamp body is detachably connected to the rotating bracket; when not in use, the lamp body can be removed from the rotating bracket; it is convenient to use; and it is also easy to replace the lamp body.

[0023] The above arrangement; the rotation of the limiting member is limited by the limiting groove; and then by setting the length of the limiting groove; the angle of rotation of one rotating bracket relative to another rotating bracket is controlled.

[0024] Furthermore, it also includes a driving device, which is used to drive the rotating device 1 to rotate relative to the rotating device 2, so as to control the rotation of the rotating assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0057] like Figure 5-8 As shown; the rotating mounting member 517 is provided with a horizontal protrusion 527 along the width direction; the rotating mounting member is provided with a vertical protrusion 526 along the height direction.

[0058] like Figure 9-10 As shown; the rotating bracket 1 includes a bracket body 11 and a side cover 12 detachably connected to the bracket body 11; reference Figure 2 As shown, a hanging ring 8 is installed on one side of the bracket body 11 close to the lamp body 2. The side cover 12 is located on one side of the bracket body 11; a positioning cavity is formed between the side cover and the bracket body; and the rotating mounting member is accommodated in the rotating mounting member.

[0059] Refer to 5-6; the vertical protrusion 526 is formed by protruding upward and downward in the height direction of the rotating mounting member 517; the horizontal protrusion 527 is formed by protruding toward the side cover 12 in the width direction of the rotating mounting member 517; the upper end of the bracket body 11 and the lower end of the bracket body 11 are both provided with a groove 113 that cooperates with the vertical protrusion; the side cover 12 is provided with a groove 112 formed between the bracket body 11 and cooperates with the horizontal protrusion 527; the vertical protrusion 526 abuts against the upper end of the bracket body 11 and the lower end of the bracket body 11; the horizontal protrusion 527 abuts against the side cover 12.

[0061] A limiting fixing member (not shown in the figure) is connected between the side cover plate 12 and the rotating mounting member 517. The limiting fixing member is used to fix the rotating mounting member 517 and to limit the movement of the side cover plate 12. The horizontal protrusion 527 is provided with a threaded hole 1 5271 on the side close to the side cover 12; the side cover 12 is provided with a threaded hole 2 (not shown in the figure) corresponding to the threaded hole 1 5171.

Through the cooperation of the cover plate mounting member 1 and the positioning groove 1, the side cover can be quickly installed on the bracket body, and connected with the side cover and the rotating mounting member through the limiting fixing member. In this way, the side cover is fixed on the rotating bracket and the rotating mounting member is fixed in the rotating bracket. At the same time, because the vertical protrusion abuts against the bracket body and the horizontal protrusion abuts against the side cover, it is avoided that the force between the rotating mounting member and the rotating bracket is concentrated on the limiting fixing member. The cover plate mounting member 2 cooperates with the positioning groove 2, and the cover plate mounting member 2 cooperates with the positioning structure 3; the connection between the side cover and the bracket body is stable.

[0062] like Figure 1 As shown, it also includes a power supply device 7, and the lamp body includes a mounting frame and a light source device; the light source device is installed on the mounting frame; a heat sink is provided on the side of the mounting frame away from the light source device; the power supply device 7 is installed on the mounting frame through a power supply bracket 71 and is arranged close to the heat sink.

[0065] By cooperating with the horizontal protrusions and the vertical protrusions and the grooves one and two, the rotating bracket can fix the rotating mounting part in the horizontal and vertical directions; while the strength of the rotating mounting part is enhanced by the horizontal protrusions and the vertical protrusions, the reliability of the connection between the rotating mounting part and the rotating bracket is also enhanced; and the rotating connection assembly is detachably connected to the rotating connection mechanism through the side cover and the rotating bracket, which is convenient for installation and disassembly. By cooperating the rotating groove 1 514 with the rotating part 3 522, the rotating groove 2 523 with the rotating part 1 512, and the rotating groove 3 524 with the rotating part 2 513, the shear force on the rotating assembly 5 is dispersed, thereby reducing the shear force on the rotating fixed part. At the same time, since the rotating part 1 512, the rotating part 3 522 and the rotating part 2 are staggered, the rotating parts cooperate with different rotating grooves, the outer wall surface of the rotating part 3 522 slides and rubs against the inner wall surface of the rotating part 1 512, and the inner wall surface of the rotating part 3 522 slides and rubs against the outer wall surface of the rotating part 2 513, increasing the contact area between the rotating device 1 501 and the rotating device 2 502, and increasing the friction between the rotating device 1 501 and the rotating device 2 502, avoiding the situation where one of the contact surfaces of the rotating device 1 501 and the rotating device 2 502 is worn to reduce the damping feeling. By matching the rotating member with the rotating groove, and by matching the different wall surfaces of the rotating device 1 with the different wall surfaces of the rotating device 2, the pressure of the different wall surfaces supporting the rotating connection assembly is reduced, so that the degree of wear of each wall surface is reduced and the service life is extended. At the same time, the positions of the rotating mounting hole 1 and the rotating mounting hole 2 are associated with the rotating member and the rotating groove; when the rotating member matches the rotating groove, the rotating mounting hole 1 will be aligned with the rotating mounting hole 2, which is convenient for installation and will not cause installation deviation.

[0066] The working method of the plant lighting device includes the following steps:

[0067] (1). If the lighting device is in an unfolded state, proceed to step (8); if the lighting device is in a folded state, proceed to step (2);

[0068] (2) Determine whether the lighting device needs to be deployed; if so, proceed to step (3);
