[0036] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The schematic implementation methods of the present invention and their descriptions are only used to explain the present invention and are not intended to limit the present invention. Example

[0037] like Figures 1 to 8 As shown, the utility model includes a lamp body 1, including a mounting frame 3 installed on the inner wall of the tunnel, an opening 2 is provided on one side of the mounting frame 3, and a plurality of connecting columns 14 for being inserted into the opening 2 are provided on the lamp body 1. The connecting columns 14 are located on the side walls of the mounting frame 3 and are provided with a plurality of limiting grooves, which are distributed circumferentially along the connecting columns 14. An elastic member 11 and a limiting block 12 are provided in the limiting groove, and the limiting block 12 is used to limit the connection column 14 from being pulled out from the opening 2; an unlocking member is also provided in the mounting frame 3, and the unlocking member is used to return the limiting block 12 to the limiting groove.

[0038] In view of the existing technology, when installing the lamp body 1 in the tunnel, the installer usually needs to stand on a ladder and then hold the lamp body 1 with one hand and install the bolts with the other hand to achieve the fixation between the lamp body 1 and the mounting frame in the tunnel. However, the above method results in a low installation efficiency of the lamp body 1. At the same time, since the specifications of the lamp body 1 used in the tunnel are usually large, the installation of the lamp body 1 is relatively troublesome. For this reason, the present technical solution is provided with a connecting column 14 on the existing lamp body 1, and a mounting frame 3 is also provided on the inner wall of the tunnel. The mounting frame 3 is distributed along the length direction of the tunnel, and an opening 2 for installing the connecting column 14 of the lamp body 1 is provided on the side wall of the mounting frame 3. At the same time, the opening 2 is provided to facilitate the placement of the cable for powering the lamp body 1 into the mounting frame 3 from the opening 2, avoiding the exposure of the cable to the outside; and in order to achieve rapid installation between the lamp body 1 and the mounting frame 3 When the lamp body 1 is installed, the limit block 12 is first retracted into the limit groove, and then the connecting column 14 on the lamp body 1 is inserted into the opening 2. When the limit block 12 enters the installation frame 3 through the opening 2, the limit block 12 extends out of the limit groove under the action of the elastic member 11, and the connecting column 14 is constrained in the installation frame 3 by the limit block 12, thereby realizing quick assembly between the lamp body 1 and the installation frame 3.

[0039] When the lamp body 1 needs to be removed from the mounting frame 3 for maintenance, since an unlocking piece is provided in the mounting frame 3, the unlocking piece can be used to squeeze the limit block 12 into the limit groove, removing the constraint of the limit block 12 on the connecting column 14, so that the connecting column 14 can be quickly pulled out from the opening 2 of the mounting frame 3, thereby facilitating the removal of the lamp body 1 from the mounting frame 3. Compared with the traditional connection method using bolts, it not only improves the loading and unloading efficiency of the lamp body 1, but also avoids the thread wear caused by repeated use of the bolts for a long time, which affects the stability of the lamp body 1.

[0040] The installation frame 3 is a square tube structure. Both the upper surface and the lower surface of the installation frame 3 are provided with convex edges 5 , and embedded bolts 6 are provided in the convex edges 5 .

[0041] In this embodiment, the installation frame 3 is a square tube structure. This design can reduce the overall weight of the installation frame 3. At the same time, in order to ensure that the installation frame 3 can be stably fixed on the inner wall of the tunnel, a convex edge 5 for installing embedded bolts 6 is also provided on the installation frame 3. When the tunnel is built, mounting holes matching the embedded bolts 6 are reserved on the inner wall. In this way, the installation frame 3 can be stably fixed on the inner wall of the tunnel using the embedded bolts 6.

[0042] A positioning rod 15 is further provided on the inner wall of the mounting frame 3; a positioning blind hole is provided at the end of the connecting column 14 away from the lamp body 1, the positioning rod 15 is inserted into the positioning blind hole, and the outer diameter of the connecting column 14 is consistent with the inner diameter of the positioning blind hole.

[0043] Since the limit block 12 is provided, the connecting column 14 can be constrained to move axially along the connecting column 14 in the opening 2 of the mounting frame 3, but the connecting column 14 is not constrained in the length direction of the opening 2. In order to ensure that the connecting column 14 can be stably fixed in the opening 2, a positioning rod 15 is provided on the inner wall of the mounting frame 3. In this way, when the lamp body 1 is connected to the mounting frame 3, the connecting column 14 is inserted into the opening 2 of the mounting frame 3, and the positioning blind hole at the end of the connecting column 14 is ensured to be aligned with the positioning rod 15. In this way, the provided positioning rod 15 is inserted into the positioning blind hole of the connecting column 14, and the positioning rod 15 can be used to limit the connecting column 14 to prevent the connecting column 14 from moving in the opening 2 along the length direction of the opening 2.

[0044] The lamp body 1 is provided with a heat dissipation plate 4 , and the connecting column 14 is connected to the heat dissipation plate 4 .

[0045] In order to improve the heat dissipation of the lamp body 1 in this embodiment, a heat dissipation plate 4 is fixed on the lamp body 1. The heat dissipation plate 4 is made of aluminum. In this way, the airflow in the tunnel can take away part of the heat of the lamp body 1 when passing through the heat dissipation plate 4, thereby improving the heat dissipation of the lamp body 1.

[0046] A first heat dissipation groove 22 is also provided on the side wall of the positioning rod 15. The first heat dissipation groove 22 is distributed axially along the positioning rod 15, and the first heat dissipation groove 22 penetrates the positioning rod 15 along the long side direction of the installation frame 3; a second heat dissipation groove 13 is provided on the side wall of the connecting column 14. The second heat dissipation groove 13 is connected to the first heat dissipation groove 22, and the second heat dissipation groove 13 penetrates the connecting column 14 along the long side direction of the installation frame 3.

[0047] In order to further improve the heat dissipation of the lamp body 1 in this embodiment, a first heat dissipation groove 22 is provided on the positioning rod 15, and a second heat dissipation groove 13 is provided on the connecting column 14. In this way, when the convective gas in the tunnel enters the mounting frame 3, the first heat dissipation groove 22 and the second heat dissipation groove 13 enable the airflow in the mounting frame 3 to increase the contact area with the positioning rod 15 and the connecting column 14, thereby taking away part of the heat transferred from the heat sink 4 to the connecting column 14 and the positioning rod 15.

[0048] The positioning rod 15 and the connecting column 14 are both made of aluminum with good thermal conductivity.

[0049] A heat dissipation channel 17 is provided in the heat dissipation plate 4 . The heat dissipation channel 17 is distributed along the long side of the mounting frame 3 and passes through both ends of the heat dissipation plate 4 . The second heat dissipation slot 13 is connected to the heat dissipation channel 17 .

[0050] In order to further improve the heat dissipation effect of the heat sink 4 in this embodiment, a heat dissipation channel 17 is provided on the heat sink 4. In this way, when the airflow in the tunnel passes through the heat sink 4, a part of the airflow can enter the heat dissipation channel 17, increasing the contact area between the airflow and the heat sink 4, thereby improving the heat dissipation effect of the lamp body 1; at the same time, since the second heat dissipation groove 13 is connected to the heat dissipation channel 17, when the airflow in the mounting frame 3 passes through the second heat dissipation groove, a part of the airflow can enter the heat dissipation channel 17 through the second heat dissipation groove, thereby improving the heat dissipation effect of the heat sink 4.

[0051] The upper and lower surfaces of the mounting frame 3 are both provided with first strip openings 19, the number of which is the same as the number of connecting columns 14, and the first strip openings 19 are distributed axially along the positioning rod 15; the unlocking member includes an unlocking ring 8 and a movable rod 7, the unlocking ring 8 is sleeved on the positioning rod 15, one end of the movable rod 7 is located in the first strip opening 19, and the other end is connected to the unlocking ring 8, the movable rod 7 is used to drive the unlocking ring 8 to move axially along the connecting column 14, and a limiting nut is also provided on the movable rod 7; the end face of the limit block 12 facing the positioning rod 15 is provided with a bevel 16.

[0052] In this embodiment, in order to ensure that the unlocking member can squeeze the limit block 12 into the limit groove to unlock the limit block 12, the unlocking member includes an unlocking ring 8 and a movable rod 7. When the lamp body 1 needs to be removed from the mounting frame 3, the limit nut on the movable rod 7 is loosened, and then the movable rod 7 is pulled toward the lamp body 1. The movable rod 7 drives the unlocking ring 8 to move on the surface of the connecting column 14. When the unlocking ring 8 reaches the limit block 12, the end of the unlocking ring 8 acts on the bevel 16 of the limit block 12, forcing the limit block 12 to retract into the limit groove, thereby quickly removing the constraint of the limit block 12 on the connecting column 14, ensuring that the lamp body 1 can be quickly removed from the mounting frame 3.

[0053] The first strip-shaped opening 19 is also used to facilitate the determination of the position of the positioning rod 15 so as to align the positioning rod 15 with the connecting column 14 when the lamp body 1 is installed.

[0054] The inner diameter of the unlocking ring 8 is larger than the outer diameter of the connecting column 14 . A plurality of movable balls 10 are provided on the inner wall of the unlocking ring 8 . The distance between two movable balls 10 located on the same radial direction of the unlocking ring 8 is consistent with the outer diameter of the connecting column 14 .

[0055] In this embodiment, in order to reduce the contact between the inner wall of the unlocking ring 8 and the connecting column 14 and avoid wear caused by repeated use of the unlocking ring 8 and the connecting column 14, a movable ball 10 is further provided on the inner wall of the unlocking ring 8. The movable ball 10 is embedded in the unlocking ring 8 and can rotate freely in the unlocking ring 8. Therefore, when the unlocking ring 8 moves on the connecting column 14, the set movable ball 10 is used to perform rolling friction with the connecting column 14, and the movable ball 10 can be used to press the limit block 12 into the limit groove, thereby unlocking the limit block 12.

[0056] A connecting rod 9 is provided on the inner wall of the installation frame 3 , and the connecting rod 9 axially penetrates the unlocking ring 8 .

[0057] In this embodiment, in order to avoid the unlocking ring 8 from being misplaced in the vertical direction, which makes the unlocking ring 8 unable to move smoothly to the connecting column 14, a connecting rod 9 is also provided on the mounting frame 3. The connecting rod 9 can be used to move the unlocking ring 8 in the horizontal direction on the connecting rod 9, but the unlocking ring 8 cannot move in the vertical direction.

[0058] A slide groove is also provided on the inner wall of the installation frame 3, and a slider is provided in the slide groove, and the slider is connected to the connecting rod 9; the upper surface and the lower surface of the installation frame 3 are both provided with a second strip opening 21, and the second strip opening 21 is distributed along the long side direction of the installation frame 3, and the first strip opening 19 is connected to the second strip opening 21; the upper surface and the lower surface of the installation frame 3 are both provided with a plurality of third strip openings 23, and the third strip openings 23 are connected to the second strip openings 21, and the spacing between two adjacent third strip openings 23 is consistent with the spacing between two adjacent connecting columns 14.

[0059] In actual use, the installer may insert the connecting post 14 into the opening 2 of the installation frame 3 without aligning the connecting post 14 with the positioning rod 15. In this state, the connecting post 14 cannot be smoothly removed from the opening 2 and reinstalled under the action of the limit block 12. In order to prevent the above situation from happening, a slide groove is provided on the inner wall of the installation frame 3, and a slider connected to the connecting rod 9 is provided in the slide groove. In this way, the position of the unlocking ring 8 in the installation frame 3 can be adjusted by using the provided slide groove, so that the unlocking ring 8 can be moved to the position of the connecting post 14, and then the unlocking ring 8 is used to unlock the limit block 12 on the connecting post 14. After taking the connecting post 14 out of the opening 2, align the connecting post 14 with the positioning rod 15 and then reinstall the lamp body 1.

[0060] Specifically, when it is found that the connecting post 14 and the positioning rod 15 are aligned, the connecting post 14 is inserted into the opening 2, and the position of the connecting post 14 in the opening 2 is first moved so that the connecting post 14 is at the projection of the third strip opening 23, and then the movable rod 7 is moved from the first strip opening 19 to the second strip opening 21, and the second strip opening 21 and the sliding groove are used to adjust the position of the unlocking ring 8 so that the movable rod 7 is in the third strip opening 23, and then the movable rod 7 is moved along the direction of the third strip opening 23 so that the unlocking ring 8 can be sleeved on the connecting post 14, and the unlocking ring 8 is used to unlock the limit block 12 on the connecting post 14. After the connecting post 14 is taken out from the opening 2, the connecting post 14 is installed according to the position of the first strip opening 19, so that the connecting post 14 can be smoothly aligned with the positioning rod 15.

[0061] In order to conveniently distinguish the first strip opening 19 from the third strip opening 23, the end of the first strip opening 19 is provided with a chamfered corner, and the end of the third strip opening 23 is not provided with a chamfered corner; or the first strip opening 19 and the third strip opening 23 are marked on the installation frame 3 respectively, so that the first strip opening 19 and the third strip opening 23 can be judged when installed.

[0062] In another embodiment, in order to facilitate the disassembly and assembly of the lamp body 1, a cross bar is provided between the movable bars 7 on the same horizontal plane, and the cross bar connects the multiple movable bars 7 in series. In this way, when disassembling the lamp body 1, the remaining movable bars 7 can be pulled synchronously by pulling one of the movable bars 7.

[0063] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model.
