Description
Technical Field
[0001] This utility model relates to the field of LED lighting technology, and in particular to an LED light for auxiliary lighting on the roof of engineering vehicles. Background Technology
[0002] LED lights for auxiliary roof lighting of engineering vehicles have advantages such as high brightness, long life, and waterproof and dustproof properties. They are widely used in various engineering vehicles and use high-brightness LED beads. For example, some special roof lights for dump trucks and concrete mixer trucks can illuminate the road more than 50 meters ahead. The wide illumination range can meet the lighting needs of engineering vehicles in complex environments such as night construction.
[0003] Auxiliary lighting lights are usually mounted on the roof of engineering vehicles using mounting brackets. The lamp holders can usually be rotated via a pivot, but after installation, the lights cannot be moved to rotate laterally or make small-range adjustments, which limits the use of LED lights. Utility Model Content
[0004] The purpose of this utility model is to solve the problem that lighting lamps are usually installed on the roof of engineering vehicles by means of a fixed bracket. The lamp holder of the lighting lamp can usually be rotated by a pivot. However, after installation, the lighting lamp cannot be moved to make lateral rotation or small range adjustment, which leads to certain limitations in the use of LED lamps. Therefore, this utility model proposes an LED lamp for auxiliary lighting on the roof of engineering vehicles.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: an LED light for auxiliary lighting on the roof of an engineering vehicle, comprising a housing, wherein a plurality of LED beads are disposed inside the housing, a connecting seat is fixedly connected to the bottom end of the housing, an auxiliary device is disposed below the connecting seat to facilitate the installation of the housing and the connecting seat and to allow the position of the connecting seat and the housing to be moved, and a connecting wire is disposed on the back side of the housing.
[0006] Preferably, the auxiliary device includes a grooved rod with mounting holes on both sides of its outer surface for easy connection to the roof of an engineering vehicle. The grooved rod has a sliding groove inside, with a through groove at the top of its inner wall. A sliding rod is slidably connected to the inner wall of the sliding groove, with one end of the sliding rod rotatably connected to both sides of a connecting seat. A round rod is fixedly connected to the top of the sliding rod, moving within the through groove at the top of the inner wall of the sliding groove. A round block is fixedly connected to the top of the round rod, with a spring at the bottom of the round block and a pressure block at the bottom of the spring. The upper and lower ends of the spring are fixedly connected to the bottom of the round block and the top of the pressure block, respectively.
[0007] The aforementioned components achieve the following effects: By setting a sliding rod, when installing the lighting lamp, the bottom end of the groove rod is attached to the installation position on the roof of the engineering vehicle. Then, fasteners are used to connect it to the vehicle roof through the two mounting holes on the outer surface of the groove rod. The pressure block is held on the outer surface of the pressure block and pulled to slide upward on the outer surface of the round rod, compressing the spring. Then, the sliding rod is pushed to control the sliding rod to slide on the inner wall of the groove to adjust the position of the sliding rod and the housing. Pushing the housing can control the housing to rotate up and down at one end of the sliding rod through the connecting seat to adjust the angle. At the same time, the sliding rod can be pushed to rotate left and right inside the groove with the round rod as the center, so that the housing faces different angles. After adjustment, the pressure block is released, the spring returns to its original state and pushes the pressure block to move downward, pressing the bottom end of the pressure block tightly against the outer surface of the groove rod, thus fixing the position of the sliding rod inside the groove rod and the position of the housing at one end of the groove rod. Finally, the connecting wire on the back of the housing is connected to the power supply line, and the LED beads inside the housing light up to provide illumination.
[0008] Preferably, a rubber sheet is provided at the bottom end of the pressure block, and a plurality of rubber protrusions are fixedly connected to the top end of the groove rod, the protrusions being arranged linearly at the top end of the groove rod.
[0009] The effect achieved by the above components is that when the rubber sheet at the bottom of the pressure block contacts the rubber protrusion at the top of the groove rod, it can increase the friction when the pressure block presses against the groove rod, thereby increasing the stability of the pressure block in fixing the position of the sliding rod.
[0010] Preferably, the outer surface of the pressure block is fixedly connected with two protrusions, which are located on opposite sides of the outer surface of the pressure block.
[0011] The effect achieved by the above components is that the two protrusions on the outer surface of the pressure block can be pinched more conveniently to pull the pressure block and control its upward movement on the outer surface of the round rod.
[0012] Preferably, the top of the circular block is provided with a limiting component that can restrict the position of the connecting line on one side of the housing to prevent the connecting line from getting tangled when adjusting the position of the housing.
[0013] Preferably, the limiting component includes a rotating shaft, the two ends of which are rotatably connected to the top of the outer surface of the circular block, a stop block is fixedly connected to the outer surface of the rotating shaft, and a coil spring is provided at one end of the rotating shaft, the two ends of which are fixedly connected to one side of the rotating shaft and one side of the top of the circular block, respectively.
[0014] The effect achieved by the above components is as follows: when installing LED lights, pulling the stop block rotates it away from the round block through the pivot axis, causing the coil spring to deform. Then, the connecting wire is passed between the top of the round block and the stop block. Releasing the stop block restores the coil spring to its original state, which will drive the pivot axis and the stop block to rotate downwards, pressing one end of the stop block against the outer surface of the round block, thus restricting the position of the connecting wire at the top of the round block.
[0015] Preferably, one end of the rotating shaft is fixedly connected to an operating block, and the outer surface of the operating block is provided with several protrusions.
[0016] The effect achieved by the above components is that the protrusions on the outer surface of the operating block make it easier to rotate the operating block to control the rotation of the shaft and the stop block, thus improving the convenience of using the limit components.
[0017] Preferably, metal baffles are fixedly connected to both sides of the inner wall of the block, and the outer edge of the baffles is arc-shaped.
[0018] The effect achieved by the above components is that by setting arc-shaped metal baffles, the outer surface of the housing is not easily worn when the connecting line is pulled to contact the two sides of the outer surface of the baffle during the adjustment of the position and angle.
[0019] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0020] In this invention, by setting an auxiliary device, the connecting seat at the bottom of the housing is installed at one end of the sliding rod, and the sliding rod and the housing are fixed to the top of the engineering vehicle by means of the groove rod. The horizontal position of the housing can be adjusted within a certain range by moving the sliding rod, and the orientation angle of one side of the housing can be changed by pushing the sliding rod to rotate, thereby improving the flexibility and convenience when using LED lighting.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.
[0029] The implementation of this utility model will be described in detail below with reference to specific embodiments.
[0030] In this embodiment:
[0031] like Figure 1-3 As shown, an LED light for auxiliary lighting on the roof of an engineering vehicle includes a housing 1, with a plurality of LED beads disposed inside the housing 1. A connecting seat 3 is fixedly connected to the bottom end of the housing 1. An auxiliary device 2 is disposed below the connecting seat 3 to facilitate the installation of the housing 1 and the connecting seat 3 and to allow the positions of the connecting seat 3 and the housing 1 to be moved. A connecting wire 4 is disposed on the back side of the housing 1.
[0032] Reference Figure 1-5As shown in this embodiment: the auxiliary device 2 includes a grooved rod 21. Mounting holes are provided on both sides of the outer surface of the grooved rod 21 to facilitate connection between the grooved rod 21 and the roof of the engineering vehicle. A sliding groove 22 is provided inside the grooved rod 21. A through groove is provided at the top of the inner wall of the sliding groove 22. A sliding rod 23 is slidably connected to the inner wall of the sliding groove 22. One end of the sliding rod 23 is rotatably connected to both sides of the connecting seat 3. A round rod 24 is fixedly connected to the top of the sliding rod 23. The round rod 24 moves at the through groove at the top of the inner wall of the sliding groove 22. A round block 25 is fixedly connected to the top of the round rod 24. A spring 26 is provided at the bottom end of the device, and a pressure block 27 is provided at the bottom end of the spring 26. The upper and lower ends of the spring 26 are fixedly connected to the bottom end of the round block 25 and the top end of the pressure block 27, respectively. By setting a sliding rod 23, when installing the lighting lamp, the bottom end of the groove rod 21 is placed against the installation position on the roof of the engineering vehicle. Then, fasteners are used to pass through the two mounting holes on the outer surface of the groove rod 21 and connect it to the roof of the vehicle. The pressure block 27 is pulled by holding the outer surface of the pressure block 27 and sliding it upward on the outer surface of the round rod 24 to compress the spring 26. Then, the sliding rod 23 is pushed to control the sliding rod 23 in the groove 22. The sliding rod 23 and the housing 1 are adjusted by sliding along the inner wall. Pushing the housing 1 controls its rotation up and down at one end of the sliding rod 23 via the connecting seat 3 to adjust the angle. Simultaneously, pushing the sliding rod 23 around the circular rod 24 as the center allows it to rotate left and right inside the groove 22, causing the housing 1 to face different angles. After adjustment, releasing the pressure block 27 causes the spring 26 to return to its original state, pushing the pressure block 27 downwards and pressing its bottom end against the outer surface of the groove rod 21. This adjusts the position of the sliding rod 23 inside the groove rod 21 and the position of the housing 1 at one end of the groove rod 21. After fixing, the connecting wire 4 on the back of the housing 1 is connected to the power supply line. When the power is turned on, the LED beads inside the housing 1 light up for illumination. By setting the auxiliary device 2, the connecting seat 3 at the bottom of the housing 1 is installed on one end of the sliding rod 23. The sliding rod 23 and the housing 1 are fixed to the top of the engineering vehicle by means of the groove rod 21. The horizontal position of the housing 1 can be adjusted within a certain range by moving the sliding rod 23. The orientation angle of one side of the housing 1 can be changed by pushing the sliding rod 23 to rotate, which improves the flexibility and convenience of using LED lights.
[0033] Reference Figure 2-5As shown in this embodiment: a rubber sheet is provided at the bottom end of the pressure block 27, and several rubber protrusions 28 are fixedly connected to the top end of the groove rod 21. The protrusions 28 are arranged linearly at the top end of the groove rod 21. When the rubber sheet at the bottom end of the pressure block 27 contacts the rubber protrusions 28 at the top end of the groove rod 21, it can increase the friction force when the pressure block 27 presses against the groove rod 21, and increase the stability of the pressure block 27 in fixing the position of the sliding rod 23. Two protrusions 210 are fixedly connected to the outer surface of the pressure block 27. The two protrusions 210 are located on opposite sides of the outer surface of the pressure block 27. By pinching the two protrusions 210 on the outer surface of the pressure block 27, it is easier to pull the pressure block 27 and control the pressure block 27 to move upward on the outer surface of the round rod 24.
[0034] Reference Figure 2-5 As shown in this embodiment: the top of the circular block 25 is provided with a limiting component 29, which can restrict the position of the connecting line 4 on one side of the housing 1 to prevent the connecting line 4 from getting tangled when adjusting the position of the housing 1. The limiting component 29 includes a rotating shaft 291, the two ends of which are rotatably connected to the top of the outer surface of the circular block 25. A stop block 293 is fixedly connected to the outer surface of the rotating shaft 291. A coil spring 292 is provided at one end of the rotating shaft 291. The two ends of the coil spring 292 are fixedly connected to one side of the rotating shaft 291 and one side of the top of the circular block 25, respectively. When installing the LED light, the stop block 293 is pulled to rotate away from the circular block 25 through the rotating shaft 291, causing the coil spring 292 to deform. Then the connecting line 4 is passed between the top of the circular block 25 and the stop block 293. The stop block 293 is released and the coil spring 292 returns to its original position. The original state will drive the rotating shaft 291 and the stop block 293 to rotate downwards, so that one end of the stop block 293 abuts against the outer surface of the round block 25, restricting the position of the connecting line 4 at the top of the round block 25. One end of the rotating shaft 291 is fixedly connected to the operating block 295. The outer surface of the operating block 295 is provided with several protrusions. Holding the protrusions on the outer surface of the operating block 295 makes it easier to rotate the operating block 295 to control the rotation of the rotating shaft 291 and the stop block 293, improving the convenience of using the limiting component 29. Metal baffles 294 are fixedly connected to both sides of the inner wall of the stop block 293. The outer edge of the baffle 294 is arc-shaped. By setting the arc-shaped metal baffles 294, the outer surface of the housing 1 is not easily worn when the connecting line 4 is pulled to contact the two sides of the outer surface of the stop block 293 when adjusting the position and angle.
[0035] Working principle: When installing the lighting lamp, the bottom end of the groove rod 21 is attached to the installation position on the roof of the engineering vehicle. Then, fasteners are used to connect the groove rod 21 to the vehicle roof through the two mounting holes on the outer surface of the groove rod 21. The pressure block 27 is pulled by holding the outer surface of the pressure block 27 and sliding it upward on the outer surface of the round rod 24, compressing the spring 26. Then, the sliding rod 23 is pushed to control the sliding rod 23 to slide on the inner wall of the groove 22 to adjust the position of the sliding rod 23 and the housing 1. Pushing the housing 1 can control the housing 1 to rotate up and down at one end of the sliding rod 23 through the connecting seat 3 to adjust the angle. At the same time, the sliding rod 23 can be pushed to rotate left and right inside the groove 22 with the round rod 24 as the center, so that the housing 1 faces different angles. After the adjustment is completed, the pressure block 27 is released, and the spring 26 returns to its original position. The original state will push the pressure block 27 downward to press the bottom of the pressure block 27 against the outer surface of the groove rod 21, fixing the position of the sliding rod 23 inside the groove rod 21 and the position of the housing 1 at one end of the groove rod 21. Pulling the stop block 293 will rotate it away from the round block 25 through the rotating shaft 291 and cause the coil spring 292 to deform. The connecting wire 4 will pass through the top of the round block 25 and the stop block 293. Releasing the stop block 293 and restoring the coil spring 292 to its original state will drive the rotating shaft 291 and the stop block 293 to rotate downward, pressing one end of the stop block 293 against the outer surface of the round block 25, restricting the position of the connecting wire 4 at the top of the round block 25. Finally, the connecting wire 4 on the back of the housing 1 will be connected to the power supply line, and the LED beads inside the housing 1 will light up for illumination.
[0036] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
