Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a single-point fixed lighting lamp. Background Technology

[0002] In tunnel lighting systems for highways, railways, and other engineering projects, the installation of lighting fixtures typically relies on mounting bases pre-embedded within the tunnel lining. Traditional designs generally employ double-hole or multi-hole fixing methods, using at least two mounting holes with bolts to achieve a rigid connection of the fixture. This design aims to ensure the stability of the fixture installation and provide redundant adjustment space for angle adjustment.

[0003] As research into tunnel lighting systems deepens, it has become increasingly clear that a well-designed installation structure and mounting hole location for the luminaires, combined with high-strength bolts, expansion bolts, or embedded parts, can ensure the luminaires are securely installed in the tunnel even with only one pre-reserved mounting position. This approach reduces the number of mounting holes while maintaining the luminaire's structural strength. Consequently, the single mounting hole pre-reservation technique has been proposed and gradually applied.

[0004] However, in actual use, the lamps may rotate around the mounting holes due to factors such as vibrations from vehicle movement, airflow impact, or their own weight. This rotation may cause the lamp's illumination direction to deviate from the intended position, affecting the lighting effect in the tunnel, and may even cause the light to shine directly into the driver's eyes, causing glare and affecting driving safety.

[0005] Therefore, there is an urgent need to provide a single-point fixed lighting lamp that can effectively prevent rotation during use. Utility Model Content

[0006] The purpose of this invention is to propose a single-point fixed lighting lamp to solve the problem in the prior art where the lighting lamp is easily rotated due to factors such as vibration generated by vehicle movement, airflow impact, or its own weight when it is fixed at a single point.

[0007] To achieve the above objectives, this utility model proposes a single-point fixed lighting fixture, including a single-point fixing component set on the tunnel wall, a fixing bracket detachably installed on the single-point fixing component, a lighting fixture installed on the fixing bracket, a locking structure installed on the fixing bracket and abutting against the tunnel wall, and a rotating structure set on the fixing bracket and the lighting fixture.

[0008] Optionally, the locking structure increases the friction between the fixed bracket and the single-point fixing component by abutting against the tunnel wall; the luminaire can be rotated by the rotating structure to adjust the illumination angle of the luminaire.

[0009] Optionally, the single-point fastener and the locking structure exert opposite forces on the fixed bracket. Optionally, the single-point fastener includes a fixing bolt disposed on the tunnel wall and a connecting nut mounted on the fixing bolt.

[0013] Optionally, the locking mechanism is mounted on the wall connection plate; the rotating mechanism is set on the lamp mounting plate and the lamp.

[0014] Optionally, the intermediate connecting plate has a clearance groove on the side facing the wall connecting plate that corresponds to the wall connecting plate.

[0015] Optionally, the wall panel has through holes and mounting holes located at the top and bottom of the wall panel.

[0016] Optionally, the opening direction of the through hole is perpendicular to the opening direction of the mounting hole.

[0017] Optionally, the top and bottom of the intermediate connecting plate are fitted with connecting bolts that are compatible with the mounting holes, and the intermediate connecting plate is provided with clearance holes at the middle position.

[0018] Optionally, the locking structure includes multiple threaded holes on the wall connection plate and a tightening bolt installed in the threaded holes. The length of the tightening bolt is greater than the thickness of the wall connection plate, allowing it to contact the tunnel wall.

[0019] Optionally, the rotating structure includes a rotating clearance hole provided on the lamp mounting plate, a rotating connector located in the rotating clearance hole, a limiting arc groove provided on the lamp mounting plate, a rotating connecting plate installed on the back of the lamp, a rotating connecting hole provided on the rotating connecting plate and movably connected to the rotating connector, a plurality of limiting holes provided on the rotating connecting plate, and a limiting member passing through the limiting hole and located in the limiting arc groove.

[0020] Optionally, the rotary connector includes a rotary bolt, a rotary nut mounted on the rotary bolt, and a rotary clearance hole and a rotary connection hole that are concentrically arranged.

[0021] Optionally, the limiting arc groove is arc-shaped in its orthographic projection on the lamp mounting plate, and the center of the arc coincides with the center of the orthographic projection of the rotating clearance hole on the lamp mounting plate.

[0022] Optionally, a limiting part is provided at equal angles on the groove wall of the limiting arc groove, which is used to support and limit the rotating connector.

[0023] Optionally, the orthographic projection of the limiting hole on the rotating connecting plate coincides with the orthographic projection of the limiting arc groove on the rotating connecting plate; the diameter of the limiting hole is smaller than the width of the limiting arc groove.

[0024] Optionally, the limiting member includes a threaded portion that passes through the limiting hole and the limiting arc groove, and a snap-fit ​​connector disposed at the end of the threaded portion and located within the limiting arc groove.

[0025] Compared with the prior art, this utility model provides a single-point fixed lighting lamp, which has the following beneficial effects: This single-point fixed lighting fixture uses a single-point fixing component to install the fixing bracket on the tunnel wall at a single point, allowing for single-point installation of the light fixture. Combined with a locking structure, it applies a force opposite to that exerted by the single-point fixing component on the fixing bracket, increasing the force between them and the friction to prevent rotation. Furthermore, the friction between the locking structure and the tunnel wall further prevents rotation, ensuring the light fixture's illumination direction doesn't deviate from the predetermined position, thus maintaining the tunnel's lighting effect and guaranteeing safer traffic flow.

[0034] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, illustrates the present invention. Numerous specific details are set forth in the description below to provide a thorough understanding of the invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0035] The single-point fixed lighting lamp of this application can be used in tunnel lighting and other similar applications. The following is a detailed description of a single-point fixed lighting lamp.

[0036] See appendix Figure 1 — Figure 7 The diagram shows a preferred embodiment of a single-point fixed lighting fixture according to this application. The single-point fixed lighting fixture includes a single-point fixing member 1 disposed on the tunnel wall, a fixing bracket 2 detachably mounted on the single-point fixing member 1, a lighting fixture 3 mounted on the fixing bracket 2, a locking structure 4 mounted on the fixing bracket 2 and abutting against the tunnel wall, and a rotating structure 5 disposed on the fixing bracket 2 and the lighting fixture 3.

[0037] This invention, through the setting of the single-point fixing component 1, allows the fixing bracket 2 to be installed on the tunnel wall at a single point, thereby enabling the lamp 3 to be installed on the tunnel wall in a single-point fixing manner. The setting of the fixing bracket 2 provides an installation position for the lamp 3. The setting of the locking structure 4 is used to apply force to the fixing bracket 2, increase the friction between the single-point fixing component 1 and the fixing bracket 2, and reduce the probability of the fixing bracket 2 rotating around the single-point fixing component 1. At the same time, the contact between the locking structure 4 and the tunnel wall also generates friction, further preventing the fixing bracket 2 from rotating around the single-point fixing component 1, thereby preventing the lamp 3 from rotating and causing the illumination direction of the lamp 3 to deviate from the predetermined position, affecting the lighting effect in the tunnel.

[0038] It should be noted that the locking structure 4 exerts a force on the fixed bracket 2 to move the fixed bracket 2 away from the tunnel, while the single-point fixing component 1 exerts a force on the fixed bracket 2 to move the fixed bracket 2 closer to the tunnel; the lamp 3 can be rotated by the rotating structure 5 to adjust the illumination angle of the lamp 3.

[0039] See appendix Figure 1 and Figure 2 As shown, in this utility model, the single-point fixing component 1 includes a fixing bolt 11 set on the tunnel wall and a connecting nut 12 installed on the fixing bolt 11; the fixing bracket 2 is detachably installed on the fixing bolt 11; wherein, a washer 111 is fitted on the fixing bolt 11, and the washer 111 is located between the wall connecting plate 21 and the connecting nut 12.

[0040] The present invention provides installation conditions by setting the fixing bolt 11, so that the fixing bracket 2 can be installed at a single point; the fixing nut 12 is used to fix the fixing bracket 2 on the fixing bolt 11; the washer 111 can effectively prevent the connecting nut 12 from loosening due to vibration.

[0041] See appendix Figure 2 — Figure 6 As shown, in this utility model, the fixed bracket 2 includes a wall connecting plate 21 that is detachably mounted on the fixing bolt 11, an intermediate connecting plate 22 mounted on the wall connecting plate 21, and a lamp mounting plate 23 disposed on both sides of the intermediate connecting plate 22.

[0042] This utility model provides installation conditions for the locking structure 4 through the setting of the wall connecting plate 21; the setting of the intermediate connecting plate 22 is used to connect the lamp mounting plate 23 to the wall connecting plate 21, so that the lamp 3 can be installed; the setting of the lamp mounting plate 23 is used to provide conditions for the installation of the lamp 3.

[0043] See appendix Figure 4 — Figure 6 As shown, in this utility model, the intermediate connecting plate 22 is provided with a relief groove 221 corresponding to the wall connecting plate 21 on the side facing the wall connecting plate 21; the wall connecting plate 21 is provided with a through hole 211 and a mounting hole 212; the top and bottom of the intermediate connecting plate 22 are equipped with connecting bolts 222 that are compatible with the mounting holes 212.

[0044] The present invention uses the clearance groove 221 to avoid the wall connecting plate 21, so as to ensure that the intermediate connecting plate 22 can be installed on the wall connecting plate 21; and uses the through hole 211 to install the intermediate connecting plate 22 on the wall connecting plate 21 with the connecting bolt 222.

[0045] See appendix Figure 1 and Figure 2 As shown, in this utility model, the locking structure 4 includes multiple threaded holes 41 provided on the wall connecting plate 21, and a tightening bolt 42 installed in the threaded holes 41. The length of the tightening bolt 42 is greater than the thickness of the wall connecting plate 21, allowing it to contact the tunnel wall. It should be noted that a rubber pad can be installed on the end of the tightening bolt 42, that is, the end of the tightening bolt 42 that contacts the tunnel wall.

[0046] This utility model provides installation conditions for the tightening bolt 42 by providing a threaded hole 41. With the tightening bolt 42, it is screwed into the threaded hole 41. As the tightening bolt 42 is tightened, it will penetrate the threaded hole 41, and the end of the tightening bolt 42 will press against the tunnel wall. As the tightening bolt 42 is continuously tightened, the force exerted by the tightening bolt 42 on the tunnel wall will continuously increase, while the force exerted by the wall connecting plate 21 will move away from the tunnel wall. By limiting the thickness of the tightening bolt 42, it is ensured that the tightening bolt 42 can press against the tunnel wall during installation.

[0047] See appendix Figure 4 — Figure 7 As shown, in this utility model, the rotating structure 5 includes a rotating clearance hole 51 provided on the lamp mounting plate 23, a rotating connector 52 located in the rotating clearance hole 51, a limiting arc groove 53 provided on the lamp mounting plate 23, a rotating connecting plate 54 installed on the back of the lamp 3, a rotating connecting hole 55 provided on the rotating connecting plate 54 and movably connected to the rotating connector 52, a plurality of limiting holes 56 provided on the rotating connecting plate 54, and a limiting member 57 passing through the limiting hole 56 and located in the limiting arc groove 53.

[0048] This utility model provides installation conditions for the rotating connector 52 by setting the rotating clearance hole 51; by setting the rotating connector 52, in conjunction with the rotating connection hole 55, the lamp mounting plate 23 and the rotating connection plate 54 can be rotatably connected, so that the illumination angle of the lamp 3 can be rotated; by using the limiting arc groove 53 in conjunction with the limiting hole 56 and the limiting member 57, the rotation angle can be limited, preventing the rotating connection plate 54 from rotating arbitrarily during use, and avoiding the illumination direction of the lamp 3 from deviating from the predetermined position, thus affecting the lighting effect in the tunnel.

[0049] See appendix Figure 4 — Figure 7 As shown, in this utility model, the rotating connector 52 includes a rotating bolt 521, a rotating nut 522 mounted on the rotating bolt 521, and a rotating clearance hole 51 and a rotating connection hole 55 arranged concentrically.

[0050] This utility model uses a rotating bolt 521 and a rotating nut 522 to movably connect the rotating connecting plate 54 and the lamp mounting plate 23, allowing the rotating connecting plate 54 to rotate and thus manually adjust the illumination direction of the lamp 3. By using a rotating clearance hole 51 and a rotating connection hole 55 concentrically, it is ensured that the rotating connector 52 can pass through the rotating clearance hole 51 and the rotating connection hole 55, allowing the rotating connecting plate 54 to rotate.

[0051] See appendix Figure 4 — Figure 7 As shown, in this utility model, the orthographic projection of the limiting arc groove 53 on the lamp mounting plate 23 is arc-shaped, and the center of the arc coincides with the center of the orthographic projection of the rotating clearance hole 51 on the lamp mounting plate 23; the limiting part 531 is provided at equal angles on the groove wall of the limiting arc groove 53, and the limiting part 531 is used to support and limit the rotating connector 52.

[0052] This invention limits the arc shape of the limiting arc groove 53 to ensure that the limiting hole 56 still communicates with the limiting arc groove 53 when the rotating connecting plate 54 rotates, so that the limiting member 57 can be used for limiting. By setting the limiting part 531 to space the limiting arc groove 53, the limiting member 57 in the limiting arc groove 53 can be limited, preventing the limiting member 57 in the limiting arc groove 53 from moving arbitrarily in the limiting arc groove 53, thereby limiting the rotation angle.

[0053] See appendix Figure 4 — Figure 7 As shown, in this utility model, the orthographic projection of the limiting hole 56 on the rotating connecting plate 54 coincides with the orthographic projection of the limiting arc groove 53 on the rotating connecting plate 54; the diameter of the limiting hole 56 is smaller than the width of the limiting arc groove 53.

[0054] This utility model limits the hole diameter of the limiting hole 56 and the groove width of the limiting arc groove 53 to prevent the limiting member 57 from penetrating through the limiting arc groove 53 and the limiting hole 56, thus ensuring that the limiting member 57 can connect with the limiting hole 56 located in the limiting arc groove 53.

[0055] See appendix Figure 4 and Figure 5 As shown, in this utility model, the limiting member 57 includes a threaded portion 571 that passes through the limiting hole 56 and the limiting arc groove 53, and a snap connector 572 disposed at the end of the threaded portion 571 and located in the limiting arc groove 53.

[0056] This utility model, through the provision of the threaded portion 571, allows for locking via a nut or through threaded engagement with the limiting hole 56; through the provision of the snap-fit ​​connector 572, located within the limiting arc groove 53, it does not pass through the limiting hole 56, thereby limiting the rotation connecting plate 54 and the lamp mounting plate 23; it should be noted that the diameter of the snap-fit ​​connector 572 is larger than the diameter of the limiting hole 56 and larger than the groove width of the limiting arc groove 53 where the limiting portion 531 is located.

[0057] See appendix Figure 1 — Figure 7 As shown, the installation process of this utility model is as follows: First, the fixing bolt 11 is placed on the tunnel wall. The through hole 211 on the wall connecting plate 21 is aligned with the fixing bolt 11 and the fixing bolt 11 is placed inside the through hole 211. The washer 111 is fitted onto the fixing bolt 11 and the connecting nut 12 is tightened. Then, the tightening bolt 42 is installed in the threaded hole 41 and the end of the tightening bolt 42 is pressed against the tunnel wall. Next, the intermediate connecting plate 22 is connected to the wall connecting plate 21 by the connecting bolt 222. Then, the rotating bolt 521 is passed through the rotating clearance hole 51 and the rotating connecting hole 55 and tightened by the rotating nut 522. Then, the lamp 3 is adjusted to a suitable angle, the threaded part 571 of the limiting member 57 is inserted into the limiting arc groove 53 and into the limiting hole 56, and the snap connector 572 is placed in the limiting arc groove 53 and contacts the limiting part 531 in the limiting arc groove 53 for limiting.

[0058] The above embodiments are illustrative of this application and are not intended to limit this application. Any simple modifications to this application are within the protection scope of this application.
