Description

Technical Field

[0001] The utility model relates to the technical field of tunnel lighting, in particular to a fixing structure of a tunnel lamp. Background Art

[0002] Traditional installation methods of highway tunnel lights are generally as follows:

[0003] 1. Installed on the tunnel wall, first drill holes in the tunnel wall, install expansion bolts, and then fix the tunnel light with nuts. This method requires drilling holes at high altitude, which is time-consuming, labor-intensive and costly. In addition, the drilling process will damage the wall and affect the strength of the tunnel structure.

[0004] 2. Installed on the bridge, which is usually composed of a whole steel plate. In order to install the tunnel light, it is also necessary to drill holes in the bridge in advance at high altitude. Since the drilling position is fixed, the deviation range of the installation position needs to be strictly controlled according to the spacing of the tunnel light bracket. In addition, the drilling process of the steel plate is also difficult, which increases the overall operation difficulty. Utility Model Content

[0005] Based on this, the problem to be solved by the present invention is to provide a fixing structure for tunnel lights, which is convenient for adjusting the installation position according to the spacing of the tunnel light brackets, improving installation efficiency, saving manpower and time costs, and at the same time having strong installation stability, which can resist the risk of loosening due to vibration caused by vehicles passing through the tunnel.

[0006] The technical solution of the present utility model is as follows: a fixing structure for a tunnel light, comprising a grid bridge, a pressure plate and fasteners, wherein the grid bridge has a hollow grid-shaped mounting surface, the pressure plate comprises an upper pressure plate and a lower pressure plate, and fixing holes are provided in the middle of the upper pressure plate and the lower pressure plate, the mounting surface of the grid bridge is arranged between the upper pressure plate and the lower pressure plate, and the bracket of the tunnel light is fixed on the lower pressure plate.

[0007] Furthermore, the pressing plate is rectangular or square, and has a pair of sides whose lengths are greater than the minimum side length of the hollow grid of the mounting surface.

[0008] Furthermore, the area of ​​the pressing plate is larger than the area of ​​each hollow grid of the mounting surface.

[0009] Compared with the existing technology, the utility model adopts a "sandwich" structure design of upper and lower pressure plates and grid bridge, which provides a fixed position for the installation of tunnel lights, and then locks the "sandwich" structure and the bracket of the tunnel light through fasteners, so that the tunnel light cannot move up and down or left and right relative to the pressure plate and the grid bridge. The installation is more stable and can resist the vibration problem caused by vehicles passing through the tunnel. Moreover, the pressure plate can be installed at any grid position on the mounting surface of the grid bridge, which solves the problem of difficult-to-control installation position deviation of the spacing between tunnel light brackets. It has the advantages of easy operation, improved installation efficiency, and saving manpower and time costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. The following description is merely illustrative and does not limit the scope of protection of the present invention.

[0015] It should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0016] Please refer to Figure 1-Figure 3A fixing structure for a tunnel light comprises a grid bridge 1, two sets of pressure plates and a screw assembly 4, the grid bridge 1 having a horizontal hollow grid-shaped mounting surface, the pressure plate comprising an upper pressure plate 21 and a lower pressure plate 22, a fixing hole being provided in the middle of the upper pressure plate 21 and the lower pressure plate 22, and the mounting surface of the grid bridge 1 being provided between the upper pressure plate 21 and the lower pressure plate 22; the tunnel light 3 has two left and right brackets, each of which has a mounting hole in the middle, and the screw assembly 4 passes through the upper pressure plate 21, the grid bridge 1, the lower pressure plate 22 and the mounting hole in sequence, and each bracket of the tunnel light 3 is fixed to the lower pressure plate 22 respectively, and the tunnel light 3 is located below the pressure plate and the grid bridge 1.

[0017] Furthermore, the pressure plate is rectangular, and the long side of the pressure plate is larger than the minimum side length of the hollow grid of the installation surface. The pressure plate can be placed on the two long sides of any grid of the installation surface of the grid bridge 1, so that the grid bridge 1 can be clamped between the upper pressure plate 21 and the lower pressure plate 22 to form a "sandwich" structure installation surface. After being fixed by the screw assembly 4, the tunnel light 3 can be restricted from moving up and down and left and right relative to the pressure plate and the grid bridge 1, thereby improving the installation stability of the tunnel light 3. Installing the tunnel light 3 on the grid bridge 1 avoids the need for drilling holes in traditional steel plate bridges, and also eliminates the need to drill holes in the tunnel wall, thereby avoiding affecting the strength of the tunnel structure. It is particularly suitable for highway tunnels with relatively low requirements for light brightness or lengths not exceeding 1,000 meters, and uses low-power LED tunnel lights.

[0018] The utility model adopts a "sandwich" structure design formed by clamping the grid bridge 1 by the upper pressure plate 21 and the lower pressure plate 22, and then locks the "sandwich" structure and the bracket of the tunnel light 3 through the screw assembly 4, so that the installation of the tunnel light 3 is more stable and can resist the vibration problem caused by the shuttle of vehicles in the tunnel. Moreover, the pressure plate can be installed at any grid position on the installation surface of the grid bridge 1, which solves the problem of difficult-to-control installation position deviation of the bracket spacing of the tunnel light 3, and has the advantages of easy operation, improved installation efficiency, and saving manpower and time costs.

[0019] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
