Description

Technical Field

[0001] This utility model relates to the field of lighting device technology, and in particular to rail transit lighting devices. Background Technology

[0002] In the maintenance of tunnels, bridges, carriages, and elevated sections of rail transit systems, workers typically carry independent lighting devices. These devices are usually simple lighting fixtures, temporarily mounted on the tracks, ballast, or maintenance platforms using fixed brackets, magnetic bases, or single clamps to meet standard off-ground lighting needs. However, existing lighting fixtures have limited placement options. For example, fixtures with bases can only be placed and illuminate on the ground. In confined work environments, these fixtures are difficult to use, requiring maintenance personnel to change fixtures for different conditions. This is costly, and frequent fixture changes reduce maintenance efficiency, limiting their usability. Utility Model Content

[0003] The purpose of this utility model is to address the aforementioned shortcomings by providing a rail transit lighting device that can be used in multiple scenarios and has good applicability.

[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a rail transit lighting device, comprising: Lighting fixtures that illuminate the corresponding scene when turned on; The first mounting assembly includes a detachable housing disposed at the bottom of the lamp, two clips slidably disposed at the bottom of the housing, and an adjustment component disposed on the housing, the adjustment component being capable of driving the two clips closer to or further apart from each other; The second mounting assembly includes a platform and at least three supports hinged to the bottom of the platform. A locking component is disposed on the second mounting component to limit it when the first mounting component and the second mounting component come into contact.

[0005] Furthermore, the adjusting component includes a rotatable double-threaded screw arranged laterally inside the box, the double-threaded screw having two threads with opposite directions, one end of the double-threaded screw extending outside the box, two sliders being slidably arranged laterally on the inner side of the box, the two sliders being screwed into the two threads of the double-threaded screw, and two clamping pieces being respectively arranged at the bottom of the corresponding sliders. Rotating the double-threaded screw can drive the two sliders closer to or further apart.

[0006] Furthermore, the first mounting component also includes an anti-slip sleeve, which is disposed on the side of the housing through which the corresponding double-threaded screw passes, and the anti-slip sleeve is fitted over and in contact with the double-threaded screw.

[0007] Furthermore, the locking assembly includes two limiting paddles hinged to the top of the platform, which are distributed opposite each other on both sides of the box. Each side of the box has a slot. A coil spring is provided at the rotatable connection between the limiting paddle and the platform. The coil spring is used to drive the corresponding limiting paddle to rotate and engage with the slot.

[0008] Furthermore, a battery assembly is provided on the box body. The battery assembly includes a mounting bracket on the box body. A battery body is detachably mounted on the mounting bracket. A charging slot is provided on the top of the battery body. A corresponding plug is provided on the bottom of the lamp. The lamp can be inserted into the battery body from top to bottom with the plug and charging slot. The battery body is used to charge the lamp.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0014] Please see Figure 1-4 This utility model discloses a rail transit lighting device, including a lamp 1, which can illuminate the corresponding scene when turned on. Specifically, the lamp 1 is a small lighting device that can be held by a worker for lighting. The lamp 1 has a built-in small battery, so when in use, the worker can use the lamp 1 for lighting.

[0015] In one embodiment, the device further includes a first mounting component 2 and a second mounting component 3. The first mounting component 2 includes a housing 21 detachably mounted on the bottom of the lamp 1. Two clips 24 are slidably mounted on the bottom of the housing 21. An adjustment component is provided on the housing 21, which can drive the two clips 24 to move closer or further apart. The second mounting component 3 includes a platform 31 and at least three brackets 32 hinged to the bottom of the platform 31. A locking component 4 is provided on the second mounting component 3 to limit the contact between the first mounting component 2 and the second mounting component 3.

[0016] In practice, the lamp 1, the first mounting component 2, and the second mounting component 3 are installed together. At this time, the lamp 1 can be placed on the ground by the bracket 32, which facilitates the maintenance of the rail transit maintenance site. When the second mounting component 3 is removed, the two clamping pieces 24 can be moved closer or further apart by the adjustment component, so that they can be clamped at the corresponding thickness position, so that the lamp 1 can illuminate the places that cannot be placed on the ground. When the first mounting component 2 is removed, the staff can hold the lamp 1 or fix the lamp 1 to the head by the strap or other structure, so that the lamp can illuminate the relatively small environment. The device can be adaptively adjusted according to the usage scenario, thereby effectively improving its application range.

[0017] In one embodiment, the adjusting component includes a rotatable double-threaded screw 22 that is laterally disposed inside the housing 21. The double-threaded screw 22 has two threads with opposite directions of rotation. One end of the double-threaded screw 22 extends outside the housing 21. Two sliders 23 are laterally slidably mounted on the inner side of the housing 21. The two sliders 23 are screwed into the two threads of the double-threaded screw 22. Two clamps 24 are respectively installed at the bottom of the corresponding sliders 23.

[0018] In practice, the operator holds the end of the double-threaded screw 22 located outside the box 21 and rotates it. At this time, the rotation of the double-threaded screw 22 can drive the two sliders 23 to move closer or further away from each other, thereby driving the two clamping pieces 24 to move relative to each other. In addition, the clamping pieces 24 are semi-circular in shape. When the two clamping pieces 24 come into contact with each other, they become circular. A corresponding circular hole is opened at the center of the platform 31. When the first mounting component 2 and the second mounting component 3 are assembled, the two clamping pieces 24 will pass through the circular hole and extend to their bottom.

[0019] In one embodiment, the first mounting component 2 further includes an anti-slip sleeve 25, which is installed on the side of the housing 21 through which the corresponding double-threaded screw 22 passes, and the anti-slip sleeve 25 is fitted over and in contact with the double-threaded screw 22.

[0020] In specific implementation, the anti-slip sleeve 25 can be a rubber sleeve, which contacts the double-threaded screw 22 and can increase the torque required for the double-threaded screw 22 to rotate. Therefore, when the double-threaded screw 22 is stationary, the anti-slip sleeve 25 can prevent it from rotating, thus improving the safety of use.

[0021] In one embodiment, the locking component 4 includes a limiting paddle 41 hinged to the top of the platform 31. There are two limiting paddles 41, which are distributed opposite to each other on both sides of the box 21. The corresponding sides of the box 21 are provided with slots 42. A coil spring (not shown in the figure) is installed at the rotatable connection between the limiting paddle 41 and the platform 31.

[0022] In practice, the coil spring can drive the corresponding limiting plate 41 to rotate and engage in the slot 42, thereby effectively fixing the box 21 on the platform 31. When unlocking is required, the operator only needs to rotate the limiting plate 41 away from the box 21 until it leaves the slot 42. It should be noted that since there are few external factors interfering with the placement and use of this device, the operator can use a coil spring with appropriate torque to achieve a better fixing effect.

[0023] In one embodiment, a battery assembly 5 is provided on the housing 21. The battery assembly 5 includes a mounting bracket 51 mounted on the housing 21. A battery body 52 is detachably mounted on the mounting bracket 51. A charging slot 53 is provided on the top of the battery body 52. ​​A corresponding plug is provided on the bottom of the lamp 1. The battery body 52 is used to charge the lamp 1. A bolt 54 is screwed onto the mounting bracket 51. A corresponding screw hole is provided on the lamp 1.

[0024] In practice, the lamp 1 can be inserted into the battery body 52 from top to bottom with the plug and charging slot 53. At this time, the battery body 52 can charge the small battery inside the lamp 1. In addition, through the configuration of bolts 54 and screw holes, the lamp 1 can be effectively fixed after being installed on the top of the battery body 52. ​​A rotating shaft can be set between the mounting bracket 51 and the box 21. The rotating shaft is rotatably engaged with the mounting bracket 51 and there is rotational damping between them. Therefore, the mounting bracket 51 can be rotated and adjusted, thereby driving the lamp 1 to rotate synchronously to change the illumination angle.

[0025] In one embodiment, the luminaire 1 includes a lighting lamp 11 and a hanging ring 12 mounted thereon.

[0026] With this design, the lighting lamp 11 can be attached to the head by attaching a strap at the hanging ring 12, making it easier for staff to perform subsequent maintenance.

[0027] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0028] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0029] Additionally, "multiple" refers to two or more.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
