Description

Technical Field

[0001] The present application relates to the technical field of lighting equipment, and in particular to a bridge and tunnel lighting bracket structure. Background Art

[0002] Lamps used for bridge and tunnel lighting are generally installed on brackets, and the lamps are often completely wrapped inside the brackets. When the lamps are damaged or need to be replaced for other reasons, it is troublesome to dismantle the lamps and the construction is difficult. Utility Model Content

[0003] In view of the above problems, this application proposes a bridge and tunnel lighting bracket structure and adopts the following technical solutions.

[0004] A bridge and tunnel lighting bracket structure includes a mounting member and a lighting fixture. The mounting member includes a mounting base, a sleeve, and multiple U-shaped blocks. The mounting base is connected to the sleeve. Each side of the U-shaped block is affixed to the inner wall of the sleeve, and the multiple U-shaped blocks are arranged in an interval. Each U-shaped block has a groove inside.

[0005] The lighting fixture includes an insert and a mounting frame. The insert is connected to the upper portion of the mounting frame. The mounting frame has a structure capable of accommodating and supporting the lamp. A plurality of protrusions are fixed to the outer wall of the insert. The number of U-shaped blocks is the same as the number of protrusions. Each protrusion can pass through the gap between any two adjacent U-shaped blocks. The multiple protrusions can be inserted into the grooves of the multiple U-shaped blocks one by one.

[0006] By adopting the above technical solution, when installing a lamp on a bridge or tunnel, the first step is to install the mounting piece on the bridge or tunnel. The mounting piece can be fixed to the inner wall of the bridge or tunnel using expansion screws, etc., and the power cord is passed through the casing. The lamp is then installed in the mounting frame, the lamp wires are pulled upward from the insertion tube, and the terminal of the lamp wires is connected to the terminal of the power cord. The insertion tube is then inserted into the casing. The insertion process specifically involves sliding the protrusion through the gap between adjacent U-shaped blocks, then rotating the lamp mounting piece so that the protrusion moves above the groove, and then pulling the lamp mounting piece downward so that the multiple protrusions are embedded one by one in the grooves of the multiple U-shaped blocks, thus completing the installation of the lamp. Based on the installation structure of the bridge and tunnel lighting bracket structure of the present application, when the lamp is damaged or needs to be replaced due to other needs, it is only necessary to lift the lamp mounting part upwards to disengage the protrusion from the groove, and then rotate the lamp mounting part so that the protrusion is relative to the gap between the U-shaped blocks, and then pull out the plug of the lamp mounting part to expose the joint between the power cord and the lamp wire, unplug the docking terminal, remove the combination of the lamp mounting part and the lamp, and the lamp can be easily replaced. The installation and disassembly construction of this installation structure is not difficult.

[0007] A preferred structure of the bridge and tunnel lighting bracket structure is that each of the U-shaped blocks is integrally formed on the inner wall of the sleeve, and each of the protrusions is integrally formed on the outer wall of the insert.

[0008] By adopting the above technical solution, the U-shaped block and the protrusion installation structure are firm and not easy to fall off after docking with each other. The U-shaped block half wraps and supports the protrusion upward, making it difficult for the lamp to fall down.

[0009] A preferred structure of the bridge and tunnel lighting support structure is that each of the U-shaped blocks has the same shape and size. The grooves of each of the U-shaped blocks face the same direction. Each of the U-shaped blocks is located at the same cross-sectional height of the insert tube. The spacing between any two adjacent U-shaped blocks is equal.

[0010] By adopting the above technical solution, when the cannula is inserted into the sleeve at any rotation angle, all the protrusions can be embedded one by one into the grooves of each U-shaped block, which is convenient for installation.

[0011] A preferred structure of the bridge and tunnel lighting support structure is that the two sides of each U-shaped block are of different heights, and the high side of each U-shaped block is flanked by the low side of an adjacent U-shaped block.

[0012] By adopting the above technical solution, the protrusion can be screwed into the groove of the U-shaped block from the lower side and blocked by the higher side. Then the protrusion can be lowered to be embedded in the groove, which reduces the construction difficulty.

[0013] A preferred structure of the bridge and tunnel lighting bracket structure is that the height of the low side is greater than the height of the protrusion.

[0014] By adopting the above technical solution, the left and right sides of the protrusion are completely blocked by the high side and the low side, and are not easily deformed.

[0015] A preferred structure of the bridge and tunnel lighting bracket structure is that when the plurality of protrusions are embedded one by one in the grooves of the plurality of U-shaped blocks, the outer wall of the inserting tube fits the U-shaped blocks, and the protrusions fit the inner wall of the sleeve.

[0016] By adopting the above technical solution, the insert tube and the sleeve fit each other tightly, the connection is tight, the lighting fixture shakes little, and the structure is stable.

[0017] A preferred structure of the bridge and tunnel lighting bracket structure is that the mounting frame includes a receiving frame and two clamping frames. The receiving frame is a bar-shaped body with a U-shaped cross section. Both ends and the bottom of the receiving frame are open. The insertion tube is connected to the middle of the upper portion of the receiving frame. The two clamping frames are bar-shaped bodies with a U-shaped cross section. The two clamping frames are fixed to both sides of the lower end of the receiving frame. The openings of the two clamping frames face each other.

[0018] By adopting the above technical solution, the lamp can enter from any end of the installation frame, the lamp body enters the accommodating frame, the connecting structures on both sides of the lamp slide into the two clamping frames, and finally installed and fixed.

[0019] A preferred configuration of the bridge and tunnel lighting support structure includes a lamp. The lamp comprises a rectangular body and a connecting portion. The connecting portion includes lugs protruding from two sides of the body. The two lugs of the connecting portion are adapted to slide into the two clamping frames and are locked to each other by fasteners connecting the clamping frames and the lugs in series.

[0020] By adopting the above technical solution, the lamp can be easily installed and disassembled, and the lamp can be firmly fixed on the installation frame.

[0021] A preferred structure of the bridge and tunnel lighting bracket structure is that the clamping frame includes an upper plate and a lower plate, and the distance between the upper plate and the lower plate is equal to the thickness of the lug.

[0022] By adopting the above technical solution, the clamping frame fixes and clamps the lamp, and the lamp is not easy to shake.

[0023] A preferred structure of the bridge and tunnel lighting bracket structure is that when the two lugs of the connecting portion slide into the two clamping frames, the distance between the upper surface of the lamp body and the top surface of the accommodating frame is 5 to 10 cm.

[0024] By adopting the above technical solution, the space between the upper surface of the lamp body and the top surface of the accommodating frame is convenient for the wires to pass through and be pulled upwards out of the insertion tube, thereby facilitating the connection and installation of the wires.

[0025] In summary, the bridge and tunnel lighting bracket structure of the present application has the following beneficial effects: the bracket structure is convenient for installing lamps, with low construction difficulty; the installed lamp structure is firm and easy to disassemble and replace.

[0037] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiments. Obviously, the embodiments described are only part of the embodiments of this application, not all of them. Based on the following embodiments, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0038] like Figure 1 A bridge and tunnel lighting bracket structure includes a mounting member 1 and a lighting fixture 2. Mounting member 1, viewed from the outside, consists of a mounting base 101 and a sleeve 102. Mounting base 101 is composed of two flat ears, integrally formed on either side of the upper end of sleeve 102. The flat ears have holes for installing expansion screws to secure the bracket to a bridge suspension or tunnel wall. Sleeve 102 has openings at both ends for routing power cables.

[0039] like Figure 2 The lighting fixture 2 includes an insert 201 and a mounting frame 202. The insert 201 is connected to the upper portion of the mounting frame 202, i.e., the opening of the mounting frame 202. The insert is connected to the opening and is used to pass the wires. The insert 201 is used to be inserted upward into the sleeve 102. The mounting frame 202 includes a receiving frame 2021 and two clamping frames 2022. The receiving frame 2021 is a bar-shaped body with a U-shaped cross section. Both ends and the bottom of the receiving frame 2021 are open. The two clamping frames 2022 are both bar-shaped bodies with a U-shaped cross section and are vertically connected to the two sides of the lower end of the receiving frame 2021.

[0040] like Figure 3 The bridge and tunnel lighting support structure may further include a lamp 3 .

[0041] like Figure 4 The lamp 3 comprises a rectangular body 301 and a connecting portion. The connecting portion includes lugs 302 protruding from either side of the body 301. The lamp 3 can be inserted from either end of the mounting frame 202, with the main body of the lamp 3 entering the receiving frame 2021. The width of the receiving frame 2021 is adapted to the width of the lamp 3. The two lugs 302 of the connecting portion slide into the two clamping frames 2022 and are locked together using bolts (not shown) that pass through the lugs 302 on the upper and lower surfaces and the middle of the clamping frames 2022.

[0042] like Figure 5 The height of the interior space of the clamping frame 2022 is preferably equal to the thickness of the lugs 302 to enhance the fixing effect on the lamp 3. The distance from the inner top surface of the accommodating frame 2021 to the clamping frame 2022 should be slightly greater than the height of the lamp 3 to facilitate the sliding of the lamp 3 wires and the lamp body into the accommodating frame 2021 together. For example, when the two lugs 302 of the connecting portion slide into the two clamping frames 2022, the distance between the upper surface of the lamp body 301 and the inner top surface of the accommodating frame 2021 is 5-10 cm.

[0043] like Figure 6 , the insert tube 201 is connected to the middle of the upper part of the accommodating frame 2021, and the insert tube 201 can be perpendicular to the accommodating frame 2021. The two clamping frames 2022 are strip-shaped bodies with a U-shaped cross-section. The two clamping frames 2022 are fixed on both sides of the lower end of the accommodating frame 2021. The openings of the two clamping frames 2022 are opposite to each other. When installing the lamp 3, first install the lamp 3 into the installation frame 202, and then pass the wires of the lamp 3 upward through the installation frame 202 and pull them out upward from the insert tube 201; for this purpose, the insert tube 201 can be set shorter, and the diameter of the insert tube 201 is large enough to facilitate human hands to reach into it. After the mounting part 1 is fixed on the bridge or tunnel, the power cord will be pulled into the sleeve 102. Connect the wires passing through the insert tube 201 and the power cord in the sleeve 102 to complete the electrical connection.

[0044] like Figure 7 , viewed from a top view, there are four U-shaped blocks 103 inside the mounting member 1.

[0045] like Figure 8 The two sides of the U-shaped block 103 are of unequal height. One side is a high side 1032, and the other side is a low side 1033. Each U-shaped block 103 has a groove 1031 inside. The high side 1032, low side 1033, and bottom side of the U-shaped block 103 are all fixedly attached to the inner wall of the cannula 102. The U-shaped blocks 103 are arranged in an interval. The surface of the U-shaped block 103 can be a concave surface parallel to the outer wall of the cannula 201.

[0046] In order to fix the cannula 201 and the sleeve 102 to each other, on the one hand, four U-shaped blocks 103 are installed on the inner wall of the sleeve 102, and on the other hand, Figure 9 The outer wall of the upper end of the insert 201 is fixed with four protrusions 203. The outer side of the protrusion 203 can be a convex surface, which can adaptably fit the surface of the U-shaped block 103. The U-shaped block 103, the sleeve 102, the protrusion 203 and the insert 201 can all be made of steel, which is strong and not easy to rust.

[0047] like Figure 10 To complete the partial structural diagram of the mutual fixation of the insert tube 201 and the sleeve 102, the high side 1032 of each U-shaped block 103 is flanked by the low side 1033 of the adjacent U-shaped block 103. The four protrusions 203 are embedded one by one in the grooves 1031 of the four U-shaped blocks 103. Preferably, the height of the low side 1033 is greater than the height of the protrusions 203, so that the left and right sides of the protrusions 203 are completely blocked by the high side 1032 and the low side 1033, and are not easily deformed or slip out of the groove 1031. When the four protrusions 203 are embedded one by one in the grooves 1031 of the four U-shaped blocks 103, the outer wall of the insert tube 201 fits the concave surface of the U-shaped block 103. The protrusions 203 fit the inner wall of the sleeve 102. In this way, the insert tube 201 and the sleeve 102 fit tightly to each other, the lamp mounting unit 2 shakes less, and the structure is stable.

[0048] accomplish Figure 10 The installation process shown in the result diagram is as follows: insert tube 201 upward into sleeve 102, with the four protrusions 203 passing through the gaps between the four U-shaped blocks 103. Insert tube 201 is then rotated so that the four protrusions 203 pass through the upper ends of the lower edges 1033. The protrusions 203 then abut against the upper edges 1032. Insert tube 201 is then pulled downward, allowing the four protrusions 203 to fit one by one into the grooves 1031 of the four U-shaped blocks 103, thus securing insert tube 201 and sleeve 102. The U-shaped blocks 103 partially wrap around and support the protrusions 203 upward, providing strong support for the lamp mounting unit 2.

[0049] More specifically, to facilitate the docking and securing of the cannula 201 and the sleeve 102, each U-shaped block 103 is configured to have the same shape and size, with the grooves 1031 of each U-shaped block 103 oriented in the same direction. Each U-shaped block 103 is positioned at the same height relative to the cannula 201. The spacing between any two adjacent U-shaped blocks 103 is equal. This allows the cannula 201 to be inserted into the sleeve 102 at any rotation angle, and all protrusions 203 can be individually inserted into the grooves 1031 of each U-shaped block 103, making installation more convenient.

[0050] To sum up, when using the bridge and tunnel lighting bracket structure to install the lamp 3 on a bridge or tunnel: first install the mounting part 1 on the bridge or tunnel. The mounting part 1 can be fixed to the bridge or the inner wall of the tunnel by expansion screws, etc., and the power cord on the bridge or tunnel is passed downward through the sleeve 102; then the lamp 3 is installed into the installation frame 202, the wires of the lamp 3 are pulled upward from the insert tube 201, and the terminal of the wire of the lamp 3 is connected to the terminal of the power cord, and then the insert tube 201 is inserted into the sleeve 102. The insertion process is specifically as follows: the protrusion 203 slides through the gap between adjacent U-shaped blocks 103, and then the lamp mounting part 2 is rotated so that the protrusion 203 moves to the top of the groove 1031, and then the lamp mounting part 2 is pulled downward so that multiple protrusions 203 are embedded one by one in the grooves 1031 of multiple U-shaped blocks 103, and the installation of the lamp 3 is completed. Based on the installation structure of the bridge and tunnel lighting bracket structure of the present application, when the lamp 3 is damaged or needs to be replaced due to other needs, it is only necessary to lift the lamp mounting part 2 upwards so that the protrusion 203 disengages from the groove 1031, and then rotate the lamp mounting part 2 to make the protrusion 203 relative to the gap between the U-shaped block 103, and then pull out the plug 201 of the lamp mounting part 2 to expose the joint between the power cord and the lamp 3 wires, unplug the docking terminal, remove the combination of the lamp mounting part 2 and the lamp 3, and the lamp 3 can be easily replaced. The installation and disassembly construction of this installation structure is not difficult.
