DETAILED DESCRIPTION

[0030] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0031] like Figures 1 to 10 As shown, the present invention includes the following embodiments:

[0032] Example 1: An LED energy-saving explosion-proof lamp, comprising an embedded part 12 and a cylindrical groove 11 arranged at the center of the upper surface of the embedded part 12; a cylindrical lamp body 3 is placed in the cylindrical groove 11; a pressing groove 21 is provided on the upper surface of the embedded part 12; a pressing bar 4 is connected to the pressing groove 21 for sliding up and down; the lower end of the pressing bar 4 is connected to the bottom of the pressing groove 21 by a first spring 41; the cylindrical groove 11 and the pressing groove 21 are connected by a tooth groove 13; a gear 5 is rotatably connected to the tooth groove 13; a first notch 42 is provided on the side of the pressing bar 4 close to the gear 5; a first tooth 43 meshing with the gear 5 is provided in the middle section of the first notch 42; the first tooth 43 of the pressing bar 4 initially disengages from the gear 5; a rack 6 is vertically provided on the outer wall of the lamp body 3; the rack 6 meshes with the gear 5.

[0033] A socket 31 is provided on the lower surface of the lamp body 3; the inner bottom wall of the socket 31 is fixedly connected to the upper contact rod 71; a groove 14 is provided at the bottom of the cylindrical groove 11; the cylindrical groove 11 is connected to the disc 7 by sliding up and down; a second notch 72 is provided on the edge of the disc 7, which is staggered with the gear 5; the lower surface of the disc 7 and the bottom of the groove 14 are connected by a second spring 73; the upper surface of the disc 7 is fixedly connected to the lower contact rod 74 corresponding to the socket 31; the lower contact rod 74 is connected to the outside of the embedded part 12 through a wiring harness 75.

[0034] After a pre-buried groove is opened on the ground for placing the pre-buried part 12, the wire interface end in the pre-buried groove is connected to the wiring harness 75, and then the pre-buried part 12 is coated with glue and placed in the pre-buried groove, keeping the upper surface of the embedded part 12 flush with the ground, and then the two sockets 31 on the lower surface of the lamp body 3 are aligned with the two lower contact rods 74. Before the lamp body 3 is placed in the cylindrical groove 11, the second spring 73 will push the disc 7 close to the notch position of the cylindrical groove 11, so that the lower contact rod 74 extends out of the notch of the cylindrical groove 11 as the disc 7 moves upward, thereby facilitating the alignment of the lower contact rod 74 with the socket 31. After the socket 31 on the lamp body 3 is aligned with the lower contact rod 74, the lamp body 3 is placed on the upper surface of the disc 7. After the lower contact rod 74 is inserted into the socket 31, it will contact the upper contact rod 71, thereby realizing the connection between the two lower contact rods 74 and the upper contact rod 71, and realizing the power connection.

[0035] As the lamp body 3 is loosened, the lamp body 3 will transfer gravity to the disc 7, and the disc 7 will transfer gravity to the second spring 73, thereby compressing the second spring 73 to drive the disc 7 to move downward. The second notch 72 on the disc 7 is staggered with the gear 5, so the disc 7 can move downward over the gear 5. During the downward movement of the lamp body 3, the rack 6 will be driven to contact the gear 5, realizing the meshing of the rack 6 and the gear 5. As the lamp body 3 moves downward, the gear 5 will rotate, but in the initial state, the gear 5 is disengaged from the first tooth 43 on the pressing bar 4, and the first notch 72 is staggered with the gear 5. The position where the first tooth 43 is not set is divided into the upper first upper notch 421 and the lower first lower notch 422. The initial lower gear 5 is located in the first lower notch 422, so the rotation of the gear 5 will not cause the pressing bar 4 to move upward. As the lamp body 3 moves downward to the extreme position, the upper surface of the lamp body 3 will be flush with the upper surface of the embedded part 12. The embedded part 12 and the upper surface of the lamp body 3 flush with the ground can better protect the lamp body 3, avoid damage to the lamp body 3, and prevent pedestrians from tripping over the lamp body 3 and the embedded part 12.

[0036] When the lamp body 3 needs to be repaired or replaced, it is only necessary to prepare a new lamp body 3 and press the pressing bar 4 downward. The upper surface of the pressing bar 4 before pressing is flush with the upper surface of the embedded part 12 under the elastic force of the first spring 41. As the pressing bar 4 is pressed downward, the pressing bar 4 will squeeze the first spring 41 to compress the first spring 41. After the pressing bar 4 moves downward, it will drive the first tooth 43 to contact and mesh with the gear 5. As the pressing bar 4 moves downward, the pressing bar 4 will drive the gear 5 to rotate through the first tooth 43. During the rotation of the gear 5, the meshed rack 6 will move upward. During the upward movement of the rack 6, the lamp body 3 will be moved out of the notch of the cylindrical groove 11. After the upper end of the lamp body 3 protrudes from the notch of the cylindrical groove 11, it is convenient for the maintenance personnel to take it. As the pressing bar 4 continues to move downward, the gear 5 The wheel 5 will disengage from the engagement with the first tooth 43 and enter the range of the first upper notch 421. Then the maintenance personnel can directly lift the upper end of the lamp body 3. After lifting, the lamp body 3 will drive the socket 31 to disengage from the lower contact rod 74, releasing the connection between the lamp body 3 and the lower contact rod 74. After the lamp body 3 is moved out of the cylindrical groove 11, the pressing bar 4 is released, and the first spring 41 will push the pressing bar 4 to move upward. The pressing bar 4 will drive the first upper notch 421 and the first tooth 43 to cross the gear 5 until the first lower notch 422 on the pressing bar 4 is aligned with the gear 5. At this time, the upper end of the pressing bar 4 is flush with the upper end of the embedded part 12. Finally, the new lamp body 3 can be placed and installed. After the lamp body 3 is replaced, the upper surface of the lamp body 3 is restored to be flush with the upper surface of the embedded part 12.

[0037] The present invention divides the underground lamp into an embedded part 12 and a lamp body 3 inside the embedded part 12. When maintenance or replacement is required, the pressing bar 4 is directly pressed to drive the lamp body 3 to move upward and extend. After the lamp body 3 is removed, the installation of the lamp body 3 is completed by directly placing it. Compared with the existing maintenance method, the maintenance method is simpler and more convenient.

[0038] Example 2: The embedded part 12 is composed of an outer shell 1 and a rotating shell 2; the rotating shell 2 is rotatably connected to the inner side of the outer shell 1; the wiring harness 75 passes through the outer shell 1; the cylindrical groove 11 is arranged on the inner side of the rotating shell 2; the pressing groove 21 and the tooth groove 13 are arranged in the rotating shell 2; the groove 14 is arranged on the inner bottom wall of the outer shell 1; an annular groove 32 is provided at the lower position of the arc-shaped outer wall of the lamp body 3; the rack 6 is vertically arranged in the annular groove 32.

[0039] In this embodiment, the pressing groove 21 has a matching unlocking piece 8; the unlocking piece 8 is composed of an unlocking rod 81, a holding bar 82 and a pressing rod 83 in sequence; the lengths of the unlocking rod 81, the pressing rod 83 and the pressing bar 4 increase in sequence; the cross-section of the holding bar 82 is larger than the cross-section of the pressing groove 21; the first iron block 51 is eccentrically embedded in the gear 5; a magnet 44 is embedded in the pressing bar 4; after the unlocking rod 81 is inserted into the pressing groove 21, the third tooth 52 on the gear 5 and the second tooth 61 on the rack 6 are staggered in the vertical direction.

[0040] After a pre-buried groove corresponding to the outer side of the shell 1 is opened on the ground, glue is applied to the outer side of the shell 1 and embedded in the pre-buried groove. The rotating shell 2 will be embedded in the pre-buried groove along with the shell 1. Before the lamp body 3 is placed in the cylindrical groove 11, the rotating shell 2 is first controlled to rotate inside the shell 1. During the rotation of the rotating shell 2, the inner tooth groove 13 and the rack 6 on the outer wall of the lamp body 3 are driven to stagger in the circumferential direction. Then, the socket 31 on the lower surface of the lamp body 3 is controlled to be aligned with the lower contact rod 74. The lower contact rod 74 is controlled to be inserted into the socket 31. Then, the lamp body 3 is released and moves down into the cylindrical groove 11 under the action of its own gravity. The rack 6 on the lamp body 3 will be staggered in the circumferential direction with the gear 5. Therefore, the rack 6 on the outer wall of the lamp body 3 will not contact the gear 5 as the lamp body 3 moves down. In this way, the lamp body 3 can be smoothly When the cam 11 is in the closed position, the gear 5 is moved upwards and the lamp 3 is removed from the housing 1. When the cam 11 is in the closed position, the gear 5 is moved downwards and the lamp 3 is removed from the housing 1. When the cam 11 is in the closed position, the gear 5 is moved upwards and the lamp 3 is removed from the housing 1.

[0041] Furthermore, in the initial state, the upper end of the pressing bar 4 remains flush with the upper surface of the rotating shell 2, and the magnet 44 in the pressing bar 4 can magnetically attract the eccentric first iron block 51 inside the gear 5, so that the gear 5 remains stable in the tooth groove 13. In this state, the third tooth 52 on the gear 5 and the second tooth 61 on the rack 6 overlap in the circumferential direction of the lamp body 3. In this way, even if the rotating shell 2 is rotated to drive the gear 5 to move circumferentially around the lamp body 3, the rotating shell 2 cannot drive the gear 5 to engage with the rack 6 to form a meshing state, or even "collide". When the gear 5 cannot mesh with the rack 6, the lamp body 3 cannot be moved out of the cylindrical groove 11 by pressing the pressing bar 4, thereby further achieving the anti-theft purpose of the lamp body 3.

[0042] When the maintenance personnel need to take the lamp body 3 out of the cylindrical groove 11 for replacement, they first control the unlocking rod 81 to be inserted into the pressing groove 21 to squeeze the pressing bar 4 downward. During the downward movement of the pressing bar 4, the first tooth 43 is driven to mesh with the gear 5 and rotate. Since the gear 5 is relatively stable under the first iron block 51 and the magnet 44, the downward movement of the pressing bar 4 can smoothly mesh with the gear 5. During the meshing and rotating process of the gear 5, the third tooth 52 is driven to rotate, so that the third tooth 52 on the gear 5 and the second tooth 61 on the rack 6 are staggered in the circumferential direction of the lamp body 3. In this way, when the rotating shell 2 is driven During the circumferential movement of the gear 5 around the lamp body 3, there will be no "tooth collision" between the gear 5 and the rack 6, so that the gear 5 can smoothly engage with the rack 6. In this way, when the pressing rod 83 is turned and inserted into the pressing groove 21 to squeeze the pressing bar 4 downward, the rack 6 can be driven upward by the gear 5, so that the lamp body 3 can be smoothly moved out of the cylindrical groove 11, and the lamp body 3 is removed; because the length of the unlocking rod 81 in the unlocking part 8 determines that the gear 5 can be stuck in the rack 6, when the maintenance personnel have the unlocking part 8, the purpose of preventing the lamp body 3 from being stolen by other people can be achieved.

[0043] Embodiment 3: A retaining bar 62 is vertically provided on the side of the annular groove 32 close to the rack 6 ; the retaining bar 62 is adapted to the arc-shaped outer wall of the lamp body 3 on the side away from the lamp body 3 , and the retaining bar 62 is made of magnetic material and can be attracted by the magnet 44 .

[0044] After the gear 5 is engaged with the rack 6, it will be blocked by the bar 62, so that when the rotation of the rotating shell 2 is blocked, it indicates that the rotating shell 2 has reached the limit of rotation. In this way, the blocking limit of the bar 62 is used to prompt the rotation of the rotating shell 2.

[0045] Furthermore, since the baffle 62 is made of magnetic material and can be attracted by the magnet 44, when the gear 5 is located on either side of the baffle 62, the baffle 62 is close to the pressing bar 4. In this way, under the magnetic attraction between the baffle 62 and the magnet 44 inside the pressing bar 4, the position of the gear 5 on both sides of the baffle 62 is kept stable, ensuring the stability of the gear 5 and the rack 6 in a non-meshing or meshing state.

[0046] Example 4: The rotating shell 2 is rotatably sealed and connected to the outer shell 1; the pressing groove 21 is slidably sealed and connected to the upper end of the pressing strip 4; an annular avoidance groove 22 is provided on the inner side of the rotating shell 2; an annular elastic bag 23 is fixedly connected in the avoidance groove 22; a driving groove 24 is provided on the lower surface of the rotating shell 2; a driving block 25 is slidably sealed and connected in the driving groove 24 up and down; the driving block 25 is connected to the bottom of the driving groove 24 by a third spring 26; the driving groove 24 is connected to the inside of the annular elastic bag 23 by a first air hole 27; an arc groove 15 corresponding to the driving groove 24 is provided on the inner bottom wall of the outer shell 1; the depth of the arc groove 15 decreases successively in the arc direction, and an annular sealing groove 33 is provided on the arc outer wall of the lamp body 3 and at a position corresponding to the avoidance groove 22.

[0047] In the initial state, the driving block 25 is located at a deeper position of the arc groove 15, so that the gas or liquid in the annular elastic bag 23 flows back to the driving groove 24 along the first air hole 27, and the annular elastic bag 23 shrinks and avoids the groove 22. In this way, the lamp body 3 can be assembled with a larger gap formed with the groove wall of the cylindrical groove 11, so that the lamp body 3 can enter the cylindrical groove 11 easily. After the lamp body 3 in the cylindrical groove 11 is assembled, the rotating shell 2 is rotated to drive the driving block 25 to move along the bottom wall of the arc groove 15. The curvature of the arc groove 15 is adapted to the maximum rotation range of the rotating shell 2. During the rotation of the rotating shell 2, the driving block 25 will be driven from the deeper position of the arc groove 15 to the shallower position. The driving block 25 will move upward to overcome the third spring 26 to squeeze the medium in the driving groove 24. The medium in the driving groove 24 will enter the annular elastic bag 23 along the first air hole 27 and expand, so that the gap between the arc-shaped outer wall of the lamp body 3 and the inner wall of the cylindrical groove 11 is blocked, achieving the purpose of waterproofing and preventing subsequent rainwater from entering; and before the lamp body 3 needs to be removed, it is necessary to rotate the rotating shell 2 in the opposite direction to drive the driving block 25 to a position where the arc groove 15 is deeper, and the annular elastic bag 23 will deflate again, which is convenient for removing the lamp body 3; further, the arc-shaped outer wall of the lamp body 3 is provided with an annular sealing groove 33, so that the annular elastic bag 23 can expand into the sealing groove 33 to achieve further sealing.

[0048] The length of the harness 75 in the groove 14 is greater than the vertical movable height of the disc 7 ; the second spring 73 is arranged close to the inner wall of the groove 14 .
