Detailed implementation manners

[0046] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0047] Referring to the attached Figures 1-9 description, a tool-free installation and disassembly device for a courtyard lamp in an embodiment of the present invention, as Figure 1 and Figure 2 shown, includes an outer body 1 of the lamp. A glass cover 2 is fixedly installed at the top of the outer body 1 of the lamp. A metal sleeve 3 is fixedly installed at the top of the glass cover 2. A bulb 4 is arranged inside the outer body 1 of the lamp. A rotary clamping mechanism 5 is arranged at the bottom of the outer body 1 of the lamp. A storage and protection mechanism 6 is arranged at the top of the rotary clamping mechanism 5;

[0048] As Figure 2 and Figure 3As shown, the rotary clamping mechanism 5 includes a base 51 provided at the bottom of the lamp outer body 1. During installation, by bringing the bottom of the lamp outer body 1 close to the base 51, multiple top clamping corner blocks 52 are provided on the top of the base 51. On one side of the multiple top clamping corner blocks 52, a guide plate 53 is fixedly installed. The multiple top clamping corner blocks 52 and the guide plate 53 are arranged in correspondence with each other. The top clamping corner blocks 52 and the guide plate 53 form a complete structure. The tops of the multiple top clamping corner blocks 52 are triangularly arranged. Grooves are formed at the bottoms of the multiple top clamping corner blocks 52. The multiple top clamping corner blocks 52 are arranged in an annular equidistant pattern on the outer circumferential surface of the base 51. Thus, the multiple top clamping corner blocks 52 and the guide plate 53 are evenly distributed on the top of the base 51, so that no matter which direction the bottom of the lamp outer body 1 is in, it can correspond to the positions of the top clamping corner blocks 52 and the guide plate 53;

[0049] As Figure 3 shown, the top of the guide plate 53 is sloped. A gap is left between the outer wall of the guide plate 53 and the inner wall of the lamp outer body 1. Thus, the guide plate 53 can make the limit clamping block 54 slide to the correct position and prevent the guide plate 53 from colliding with the inner wall of the lamp outer body 1;

[0050] As Figure 3 shown, a limit clamping block 54 is provided on one side of the top clamping corner block 52. The limit clamping block 54 is fixedly installed on the inner wall of the lamp outer body 1. Thus, the limit clamping block 54 moves synchronously with the lamp outer body 1. The limit clamping block 54 and the top clamping corner block 52 are arranged in correspondence with each other. The height of the limit clamping block 54 is the same as the height of the groove formed at the bottom of the top clamping corner block 52. By rotating the lamp outer body 1 counterclockwise, the lamp outer body 1 drives the limit clamping block 54 to rotate counterclockwise synchronously. Then, when the limit clamping block 54 slides down the slope of the guide plate 53 into the groove formed at the bottom of the top clamping corner block 52, the top clamping corner block 52 clamps the limit clamping block 54;

[0051] As Figure 3 shown, a threaded hole 55 is provided at the top of the limit clamping block 54. The threaded hole 55 is formed in the inner wall of the lamp outer body 1. The horizontal height of the top of the threaded hole 55 is lower than the horizontal height of the bottom of the top clamping corner block 52. Thus, the position of the threaded hole 55 corresponds to the top of the top clamping corner block 52, and the threaded hole 55 finally lies on the top of the top clamping corner block 52;

[0052] As Figure 3As shown, a hand-tightening screw 56 is provided on one side of the threaded hole 55. The hand-tightening screw 56 is arranged corresponding to the threaded hole 55. The length of the hand-tightening screw 56 is longer than that of the threaded hole 55. Thus, the hand-tightening screw 56 can be screwed into the threaded hole 55 so that the hand-tightening screw 56 extends into the interior of the threaded hole 55 and reaches the position at the top of the top clamping angle block 52. Then, the hand-tightening screw 56 is stuck on the other side of the top of the top clamping angle block 52. Then, according to the triangular shape at the top of the top clamping angle block 52, the hand-tightening screw 56 presses against the top clamping angle block 52. Then, the bottom of the lamp outer body 1 is fixed by the top clamping angle block 52, so that the installation of the garden lamp is self-positioning, without hole alignment, and the installation is simple and fast.

[0053] As Figure 2 shown, a friction rotating cylinder 59 is provided at the top of the threaded hole 55. The friction rotating cylinder 59 is threadedly connected to the outer wall of the lamp outer body 1. The friction rotating cylinder 59 is in mutual fit with the outer wall of the lamp outer body 1. Thus, by rotating the friction rotating cylinder 59 counterclockwise, the friction rotating cylinder 59 can be clamped to the outer wall of the lamp outer body 1, so that the lamp outer body 1 rotates counterclockwise synchronously.

[0054] As Figure 3 shown, a squeezing plate 57 is provided at the bottom of the top clamping angle block 52. A support spring 58 is fixedly installed on one side of the squeezing plate 57. The support spring 58 is fixedly installed on the inner wall of the groove. The squeezing plate 57 and the limit clamping block 54 are arranged parallel to each other. Thus, when the limit clamping block 54 approaches and squeezes the squeezing plate 57, the support spring 58 is compressed by the squeezing plate 57. Then, the support spring 58 generates a reaction force to make the squeezing plate 57 squeeze the limit clamping block 54 in the reverse direction. Then, when the limit clamping block 54 is limited by the hand-tightening screw 56, the limit clamping block 54 is stressed by the reaction force of the squeezing plate 57. Then, the fixation of the limit clamping block 54 is more stable, avoiding the space shaking when the limit clamping block 54 is stuck, and thus avoiding the shaking of the bottom of the lamp outer body 1.

[0055] In specific implementation, during installation, by bringing the bottom of the lamp outer body 1 close to the base 51, then rotating the lamp outer body 1 counterclockwise to drive the limit clamping block 54 to rotate counterclockwise synchronously. Then, when the limit clamping block 54 slides along the slope of the guide plate 53 to be stuck in the groove opened at the bottom of the top clamping angle block 52, and the limit clamping block 54 is stressed and more stable by the reaction force of the squeezing plate 57. Thus, the hand-tightening screw 56 can be screwed into the threaded hole 55 and stuck on the other side of the top of the top clamping angle block 52. Then, the bottom of the lamp outer body 1 is fixed by the top clamping angle block 52, so that the installation of the garden lamp is self-positioning, without hole alignment, and the installation is simple and fast.

[0056] As Figure 3 and Figure 4As shown, the receiving and protecting mechanism 6 includes a gasket 61 disposed on the top of the base 51. A support rod 62 is fixedly installed on the top of the gasket 61. The bottom of the gasket 61 is in mutual fit with the top of the base 51. Thus, after the base 51 and the bottom of the lamp outer body 1 approach each other, the base 51 squeezes the gasket 61 upward, so that the gasket 61 moves upward to squeeze the support rod 62 to move upward synchronously. The support rod 62 and the gasket 61 are perpendicularly arranged, so that the upward movement of the gasket 61 can drive the support rod 62 to move upward synchronously;

[0057] As Figure 4 shown, a placement plate 63 is fixedly installed on the top of the support rod 62. The placement plate 63 is slidably installed on the inner wall of the lamp outer body 1. Thus, the upward movement of the support rod 62 can drive the placement plate 63 to move upward synchronously. The light bulb 4 is disposed on the top of the placement plate 63. Thus, the placement plate 63 can drive the light bulb 4 to move upward synchronously to the position height of the glass cover 2;

[0058] As Figure 4 and Figure 5 shown, two first toothed plates 64 are fixedly installed on the bottom of the placement plate 63. A gear 65 is engaged with one side of the two first toothed plates 64. Thus, the upward movement of the placement plate 63 drives the first toothed plates 64 to move upward synchronously, so as to drive the gear 65 to rotate. The gear 65 is rotatably installed on the inner wall of the lamp outer body 1. A second toothed plate 66 is engaged with one side of the gear 65. The first toothed plate 64 and the second toothed plate 66 are arranged in parallel. The second toothed plate 66 is slidably installed on the inner wall of the lamp outer body 1. One side of the second toothed plate 66 penetrates through the inner wall of the lamp outer body 1. Thus, the gear 65 drives the second toothed plate 66 to move downward synchronously on the inner wall of the lamp outer body 1;

[0059] As Figure 4 shown, a protective cover 67 is fixedly installed on one side of the second toothed plate 66. The protective cover 67 is slidably installed on the outer wall of the lamp outer body 1. Thus, the second toothed plate 66 can drive the protective cover 67 to move downward synchronously, so that the protective cover 67 moves downward from the position outside the glass cover 2 to expose the glass cover 2. Thus, the glass cover 2 can transmit the light of the light bulb 4, making the installation of the light bulb 4 convenient and safe. The height of the protective cover 67 is higher than that of the glass cover 2. Thus, when the protective cover 67 covers the outside of the glass cover 2, it can protect the glass cover 2 and prevent the glass cover 2 from being damaged by collision when not installed.

[0060] As Figure 4As shown, a shielding plate 68 is fixedly installed on one side of the second toothed plate 66. The shielding plate 68 is slidably installed on the inner wall of the lamp outer body 1. The height of the shielding plate 68 is the same as that of the second toothed plate 66. Thus, when the second toothed plate 66 does not move downward, the shielding plate 68 driven by the second toothed plate 66 extends out, and then it supplements the space required due to the sliding of the second toothed plate 66. Thus, when the second toothed plate 66 does not move downward, the integrity of the outer wall of the lamp outer body 1 is ensured. After the second toothed plate 66 moves downward, the shielding plate 68 is driven by the second toothed plate 66 to move downward and is received into the inner wall of the lamp outer body 1. At this time, the vacant area is covered by the protective cover 67.

[0061] In specific implementation, after the base 51 and the bottom of the lamp outer body 1 approach each other, the spacer 61 is upwardly extruded by the base 51, and the strut 62 is synchronously moved upward. Then, the placement plate 63 moves upward to drive the first toothed plate 64 to move upward synchronously, and the second toothed plate 66 is driven to move downward through the gear 65. Then, the second toothed plate 66 can drive the protective cover 67 to move downward synchronously to expose the glass cover 2. Then, the glass cover 2 can transmit the light of the bulb 4, and the installation of the bulb 4 is made convenient and safe.

[0062] As Figure 6 shown, a rain shielding mechanism 7 is provided on the top of the placement plate 63. The rain shielding mechanism 7 includes a top rod 71 fixedly installed on the top of the placement plate 63. The top rod 71 is perpendicularly arranged with the placement plate 63. Then, when the placement plate 63 moves upward, the top rod 71 is synchronously moved upward. The top of the top rod 71 penetrates through the top of the metal sleeve 3, and then the top rod 71 extends out of the top of the metal sleeve 3;

[0063] As Figure 6 shown, a top plate 72 is fixedly installed on the top of the top rod 71. The top plate 72 is perpendicularly arranged with the top rod 71. Then, when the top rod 71 moves upward, the top plate 72 is synchronously moved upward;

[0064] As Figure 6 shown, a limiting clamping plate 73 is fixedly installed on the top of the top plate 72. The vertical cross-section of the limiting clamping plate 73 is triangular. Then, when the top plate 72 drives the limiting clamping plate 73 to move upward synchronously, there is a gap between the bottom of the limiting clamping plate 73 and the top of the top plate 72. Then, the first rain shielding plate 74 is clamped through the gap between the limiting clamping plate 73 and the top plate 72;

[0065] As Figure 6As shown, on both sides of the top plate 72, there are first rain shields 74. The first rain shields 74 are rotatably installed on the top of the metal sleeve 3. The bottom of the first rain shield 74 is in mutual contact with the outer wall of the top plate 72, and the top of the first rain shield 74 is in mutual contact with the bottom of the limit clamping plate 73. When the first rain shield 74 is not lifted, the first rain shield 74 is horizontally stored on the top of the metal sleeve 3, thereby reducing the occupied space of the first rain shield 74, facilitating the overall storage and transfer. Then, the distance between the limit clamping plate 73 and the top plate 72 clamps the first rain shield 74 and drives it to move upward synchronously, causing the first rain shield 74 to rotate, and making the first rain shield 74 become a state inclined downward;

[0066] As Figure 6 shown, a second rain shield 75 is slidably installed on the top of the first rain shield 74. The length of the second rain shield 75 is the same as that of the first rain shield 74. A heavy plate 76 is fixedly installed on one side of the second rain shield 75. Then, due to the inclination of the first rain shield 74, the heavy plate 76 pulls the second rain shield 75 to slide down on the top of the first rain shield 74 through gravity, extending the length of the first rain shield 74 with the second rain shield 75, thereby forming a larger rain shielding area. During installation, the first rain shield 74 and the second rain shield 75 can be deployed in one step, making it more convenient to complete the installation of the rain shielding device.

[0067] As Figure 6 shown, the limit clamping plate 73 is made of rubber material, so that the limit clamping plate 73 can squeeze the top of the first rain shield 74 to clamp it. The width of the limit clamping plate 73 is the same as that of the top plate 72, and the horizontal height of the top of the limit clamping plate 73 is higher than the horizontal height of the top of the first rain shield 74, so that the limit clamping plate 73 and the top plate 72 can jointly clamp the top of the first rain shield 74.

[0068] During specific implementation, the lifting of the placing plate 63 drives the top rod 71 to drive the top plate 72 to move upward synchronously. Then, the top plate 72 drives the limit clamping plate 73, and through the distance between them, clamps the first rain shield 74 and drives it to move upward synchronously, causing the first rain shield 74 to rotate and lift to an inclined downward state. Then, the heavy plate 76 pulls the second rain shield 75 to extend the length of the first rain shield 74, forming a larger rain shielding area. During installation, the first rain shield 74 and the second rain shield 75 can be deployed in one step, making it more convenient to complete the installation of the rain shielding device.

[0069] As Figure 6 and Figure 7As shown in the figure, an opening mechanism 8 is provided on one side of the placement plate 63. The opening mechanism 8 includes a glass door cover 81 provided on one side of the glass cover 2. The width of the glass door cover 81 is smaller than the width of the glass cover 2, and the height of the glass door cover 81 is the same as the height of the glass cover 2. Thus, the glass door cover 81 can be retracted into the inner side of the glass cover 2 without being blocked, and the glass door cover 81 can be separated from the glass cover 2;

[0070] As Figure 7 shown in the figure, fixing plates 82 are fixedly installed on both sides of the glass door cover 81. A limiting plate 83 is slidably installed on one side of the fixing plate 82. The limiting plate 83 is fixedly installed at the bottom of the metal sleeve 3. The fixing plate 82 and the limiting plate 83 are arranged in parallel with each other. Thus, the glass door cover 81 drives the fixing plate 82 to slide synchronously on the limiting plate 83. A chute is provided on one side of the limiting plate 83, and the chute is opened on the inner wall of the metal sleeve 3. Thus, the fixing plate 82 can move through the chute jointly provided on one side of the limiting plate 83 and the inner wall of the metal sleeve 3. Thus, the movement of the fixing plate 82 is to slide inward first and then slide upward;

[0071] As Figure 6 shown in the figure, a pull plate 84 is rotatably installed on one side of the glass door cover 81. Thus, when the pull plate 84 is not in use, it can be retracted on one side of the glass door cover 81. The pull plate 84 and the glass door cover 81 are arranged perpendicular to each other. Thus, the glass door cover 81 can be driven to move by the pull plate 84.

[0072] As Figure 7 shown in the figure, a magnet bar 85 is fixedly installed on the top of the glass door cover 81. Thus, the glass door cover 81 can drive the magnet bar 85 to move synchronously. The magnet bar 85 and the glass door cover 81 are arranged perpendicular to each other. The outer wall of the magnet bar 85 is in mutual fit with the inner wall of the metal sleeve 3. Thus, the glass door cover 81 drives the magnet bar 85 to be mutually adsorbed with the inner wall of the metal sleeve 3. Thus, the glass door cover 81 can be magnetically fixed by the magnet bar 85. Thus, the glass door cover 81 can be opened so that the bulb 4 can be repaired, and tool-free maintenance is possible, and replacement and maintenance are convenient.

[0073] During specific implementation, the glass door cover 81 drives the magnet bar 85 to move synchronously through the pull plate 84. Thus, the glass door cover 81 drives the fixing plate 82 to slide inward first and then slide upward on the limiting plate 83 to open one side of the glass cover 2. Then, the magnet bar 85 is mutually adsorbed and fixed with the inner wall of the metal sleeve 3. Thus, the glass door cover 81 is opened and fixed so that the bulb 4 can be repaired, and tool-free maintenance is possible, and replacement and maintenance are convenient.

[0074] As Figure 8 and Figure 9As shown, an adjusting mechanism 9 is provided on the inner wall of the friction rotating cylinder 59. The adjusting mechanism 9 includes a karat plate 91 fixedly installed at the bottom of the friction rotating cylinder 59. After the outer body 1 of the lamp is limited and fixed by the top clamping corner block 52, by rotating the friction rotating cylinder 59 clockwise, the friction rotating cylinder 59 drives the karat plate 91 to rotate clockwise. A sliding card slot 92 is provided on the outer wall of the karat plate 91. The sliding card slot 92 is opened on the outer wall of the outer body 1 of the lamp. The karat plate 91 penetrates through the inner wall of the sliding card slot 92. The sliding card slot 92 is arranged in a spiral downward manner, so that the karat plate 91 slides in the sliding card slot 92 and moves downward;

[0075] As Figure 9 shown, a rotating ring 93 is fixedly installed on one side of the karat plate 91. The rotating ring 93 is perpendicular to the karat plate 91, so that the karat plate 91 drives the rotating ring 93 to move downward synchronously;

[0076] As Figure 8 shown, a counterweight ring 94 is rotatably installed on the inner wall of the rotating ring 93. The counterweight ring 94 is perpendicular to the rotating ring 93. Due to the self-weight of the counterweight ring 94, when the rotating ring 93 rotates and moves downward, it rotates on the outer wall of the counterweight ring 94, so that the counterweight ring 94 moves downward synchronously, so that the overall center of gravity inside the outer body 1 of the lamp moves downward, so that the outer body 1 of the lamp is more stable. A gap is left between the outer wall of the counterweight ring 94 and the inner wall of the outer body 1 of the lamp, so that the counterweight ring 94 does not collide with the inner wall of the outer body 1 of the lamp when moving downward.

[0077] As Figure 8 shown, a limiting post 95 is slidably installed on the inner wall of the counterweight ring 94. The limiting post 95 is fixedly installed on the inner wall of the outer body 1 of the lamp. The limiting post 95 is perpendicular to the counterweight ring 94, so that the counterweight ring 94 can be limited to move downward through the limiting post 95, so as to prevent the counterweight ring 94 from deflecting when moving downward.

[0078] In specific implementation, after the outer body 1 of the lamp is limited and fixed by the top clamping corner block 52, by rotating the friction rotating cylinder 59 clockwise to drive the karat plate 91 to rotate clockwise, so that the karat plate 91 slides in the sliding card slot 92 and moves downward, so that the karat plate 91 drives the rotating ring 93 to rotate and move downward while rotating on the outer wall of the counterweight ring 94, so that the counterweight ring 94 moves downward synchronously through the limiting post 95, so that the overall center of gravity inside the outer body 1 of the lamp moves downward, so that the outer body 1 of the lamp is more stable.
