Description

TECHNICAL FIELD

[0001] The utility model relates to a tunnel lamp technical field especially with adjusting support's tunnel lamp. BACKGROUND

[0002] With the development of urban traffic infrastructure, as an important channel connecting different areas, the importance of the internal lighting system of the tunnel is increasingly prominent. Good tunnel lighting is not only related to driving safety, but also directly affects the visual comfort of the driver and the road traffic efficiency. The traditional tunnel lamp is usually fixedly installed on the tunnel wall or the ceiling and supported by a standard support. These supports only allow the lamp to be adjusted in a limited angle along a single axis direction (for example, swinging forward and backward or swinging left and right) to adapt to specific lighting needs. However, this single-axis adjustment method has obvious limitations and cannot meet the more precise requirements for light angle and intensity in complex environments.

[0003] To overcome the above problems, some improved tunnel lamp support designs have gradually appeared in the market, which can increase the adjustability of the lamp to some extent. For example, some products allow the lamp to be independently adjusted in two perpendicular axes, that is, it can be rotated left and right in the horizontal direction and tilted up and down in the vertical direction. However, this solution is still limited by the preset adjustment axis and cannot achieve omnidirectional and dead-angle-free lighting angle adjustment, especially in the case of needing precise lighting in a specific area, the existing adjustment mechanism is not flexible enough.

[0004] Therefore, we propose a tunnel lamp with an adjusting support, which can be adjusted in any lighting direction according to actual needs. INVENTION CONTENTS

[0005] To overcome the shortcomings of the existing support that only allows the lamp to be adjusted in a limited angle along the axis direction to adapt to specific lighting needs and cannot achieve arbitrary angle adjustment, the utility model provides a tunnel lamp with an adjusting support, which can be adjusted in any lighting direction according to actual needs.

[0007] More preferably, the bottom end of the sliding rod is a spherical structure, and the spherical structure of the sliding rod is located in the annular grab sleeve.

[0008] More preferably, the adjusting assembly comprises a driving motor fixedly connected to the bottom end of the mounting plate, a gear fixedly connected to the output shaft of the driving motor, an installation ring fixedly connected to the bottom end of the mounting plate, a gear ring rotatably connected to the installation ring, the gear ring being sleeved outside the connecting sphere and the spherical sleeve, the gear ring being engaged with the gear, and an extrusion block fixedly connected to the inner side of the gear ring and in contact with the top end of the spherical sleeve.

[0010] More preferably, the sliding rod is provided with a clamping groove matched with the stabilizing block, and one end of the stabilizing block inserted into the clamping groove is in a circular arc structure.

[0011] More preferably, the hollow cylinder is provided with a strip-shaped groove on each of the longitudinal sides, and the stabilizing block is inserted into the sliding rod through the strip-shaped groove.

[0012] Compared with the prior art, the utility model has the advantages that: 1. The device is installed on the top of the tunnel through the mounting plate, when the lighting direction of the tunnel lamp needs to be adjusted, the gear ring is controlled to rotate to drive the extrusion block to rotate, the position of the extrusion spherical sleeve is changed by the rotation of the extrusion block, the extrusion block is controlled to move to the position opposite to the lighting direction, and the extrusion block extrudes the spherical sleeve on the connecting sphere to rotate at any angle, so that the tunnel lamp can be adjusted at any lighting angle.

[0013] 2. When the sliding rod is retracted into the hollow cylinder, the stabilizing block is inserted into the clamping groove to reinforce the position of the sliding rod, so as to bear part of the weight of the tunnel lamp, thereby reducing the tension between the spherical sleeve and the connecting sphere and reducing the abrasion and loosening of the spherical sleeve.
