Description

Technical Field

[0001] This utility model belongs to the field of floodlights, specifically, it relates to an LED floodlight with an adjustable installation angle. Background Technology

[0002] LED floodlights are floodlights that use light-emitting diodes as their light source.

[0003] Patent application CN212005302U discloses an LED floodlight with adjustable installation angle. Paragraph 0027 of the specification describes a device that is fixedly installed in a designated position using a substrate. When the illumination angle of the LED floodlight body needs to be adjusted, simply lift the lifting ring upwards. The lifting ring will cause the top plate to rise, and then, driven by the connecting rod, the positioning rod will be pulled out of the positioning groove. At this time, the compression spring is in a compressed state. Then, the handle can be held and rotated clockwise or counterclockwise. The handle will drive the turntable to rotate, thereby driving the rotating shaft to rotate. As the rotating shaft rotates, the connecting rope will be released or retracted. This causes the LED floodlight body to move in an arc around the hinge of the connecting block, thereby adjusting the illumination angle of the LED floodlight body. The operation is convenient. After the illumination angle of the LED floodlight body is adjusted, simply turn the handle slightly to align one of the positioning grooves with the positioning rod, and then release the lifting ring. Under the action of the compression spring, the positioning rod will automatically lock into the positioning groove, thus completing the entire adjustment work.

[0004] However, in actual use, the positioning rod slides towards the positioning groove under the action of the compression spring, and the turntable is positioned by one end of the positioning rod through the positioning groove. Because the compression spring repeatedly stretches and shortens when subjected to vibration and impact, one end of the positioning rod is easily caused to slide out of the positioning groove under the action of the compression spring elasticity, thus making it impossible to adjust the angle of the LED floodlight body.

[0005] To address these shortcomings, an LED floodlight with an adjustable installation angle is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an LED floodlight with an adjustable installation angle.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0008] An adjustable LED floodlight includes a fixing plate, with first flywheels rotatably fitted on both sides of the fixing plate, chains driving around the periphery of the first flywheels, and a fixing post fixedly fitted on one side of the fixing plate.

[0009] The floodlight body is located on one side of the fixed plate, the fixed plate is elastically and rotatably fitted on one side of the fixed post, and one side of the chain is fitted with one side of the floodlight body.

[0010] Optionally, guide rods are fixedly fitted on both sides of the fixed column, and a fixed plate is fixedly fitted on one end of each guide rod.

[0011] Optionally, two fixing blocks are fixedly fitted on one side of the floodlight body. A first through hole is opened on one side of the fixing block. The guide rod is located inside the first through hole. A torsion spring is fixedly fitted between one side of the fixing block and one side of the fixing plate. The torsion spring is sleeved on the periphery of the guide rod.

[0012] Optionally, servo motors are fixedly fitted on both sides of the fixing plate, and a rotating rod is fixedly fitted on the output end of the servo motor, with the first flywheel fixedly fitted on the rotating rod.

[0013] Optionally, a first fixing rod is fixedly fitted on both sides of the fixing plate, and a second flywheel is rotatably fitted around the periphery of the first fixing rod, the second flywheel being engaged with the chain drive.

[0014] Optionally, a second through hole is provided on one side of the second flywheel, and the first fixing rod is located inside the second through hole.

[0015] Optionally, a second fixing rod is fixedly fitted on both sides of the floodlight body, and a third flywheel is fixedly fitted around the periphery of the second fixing rod, the third flywheel being engaged with the chain drive.

[0016] Optionally, one side of the fixing plate is fixedly fitted with multiple screws.

[0017] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0018] The chain is designed to rotate the floodlight body under the action of the first flywheel, and the angle of the floodlight body can be adjusted by the chain. This reduces the problem in the prior art where one end of the positioning rod slides out of the positioning groove under the action of the compression spring, making the process of adjusting the angle of the floodlight body more convenient.

[0019] The first through hole is designed to allow the fixing block to rotate around the guide rod under the action of the floodlight body. The first through hole also guides the rotation direction of the fixing block, reducing the problem of tilting during rotation and improving the stability of the floodlight body during rotation.

[0030] Please see Figure 1-4 As shown, this embodiment provides an LED floodlight with an adjustable installation angle, including a fixing plate 100, with a first flywheel 111 rotatably fitted on both sides of the fixing plate 100, a chain 110 drivingly fitted on the periphery of the first flywheel 111, and a fixing post 102 fixedly fitted on one side of the fixing plate 100.

[0031] The floodlight body 200 is located on one side of the fixing plate 100. The fixing plate 100 is elastically and rotatably fitted on one side of the fixing post 102. One side of the chain 110 is fitted with one side of the floodlight body 200.

[0032] Working principle:

[0033] First, rotate the first flywheel 111. The first flywheel 111 drives the floodlight body 200 to rotate on one side of the fixed column 102 via the chain 110. The chain 110 is used to adjust the position of the floodlight body 200, thereby completing the adjustment of the angle of the floodlight body 200.

[0034] The chain 110 is configured to rotate the floodlight body 200 under the action of the first flywheel 111, and the angle of the floodlight body 200 can be adjusted by the chain 110. This reduces the problem in the prior art where one end of the positioning rod slides out of the positioning groove under the action of the compression spring, making the process of adjusting the angle of the floodlight body 200 more convenient.

[0035] To make the rotation of the floodlight body 200 on one side of the fixed post 102 more stable in this embodiment, improvements are made through the following structure, such as... Figure 1-4 As shown, in this embodiment, guide rods 103 are fixedly fitted on both sides of the fixed column 102. A fixed plate 104 is fixedly fitted at one end of the guide rod 103. Two fixed blocks 201 are fixedly fitted on one side of the floodlight body 200. A first through hole 202 is opened on one side of the fixed block 201. The guide rod 103 is located inside the first through hole 202. A torsion spring 105 is fixedly fitted between one side of the fixed block 201 and one side of the fixed plate 104. The torsion spring 105 is sleeved on the periphery of the guide rod 103. Servo motors are fixedly fitted on both sides of the fixed plate 100. A rotating rod 106 is fixedly fitted at the output end of the servo motor. The first flywheel 11 1. Fixedly fitted on the rotating rod 106, the fixed plate 100 has a first fixed rod 107 fixedly fitted on both sides, the first fixed rod 107 has a second flywheel 108 rotatably fitted around its periphery, the second flywheel 108 is driven by the chain 110, the second flywheel 108 has a second through hole 109 on one side, the first fixed rod 107 is located inside the second through hole 109, the floodlight body 200 has a second fixed rod 203 fixedly fitted on both sides, the second fixed rod 203 has a third flywheel 204 fixedly fitted around its periphery, the third flywheel 204 is driven by the chain 110, and a plurality of screws 101 are fixedly fitted on one side of the fixed plate 100.

[0036] In this embodiment, the servo motor is first started. The output of the servo motor drives the first flywheel 111 to rotate through the rotating rod 106. The first flywheel 111 drives the chain 110 to rotate. The chain 110 drives the second flywheel 108 to rotate around the first fixed rod 107. The chain 110 drives the second fixed rod 203 to move through the third flywheel 204. The second fixed rod 203 drives the floodlight body 200 to move. The floodlight body 200 drives the fixed block 201 to move. The fixed block 201 rotates around the guide rod 103 through the first through hole 202 and drives the torsion spring 105 to rotate, thereby completing the adjustment of the angle of the floodlight body 200.

[0037] The first through hole 202 is provided so that the fixing block 201 can rotate around the guide rod 103 through the first through hole 202 under the action of the floodlight body 200. The first through hole 202 guides the rotation direction of the fixing block 201, reduces the problem of the fixing block 201 tilting when rotating, and improves the stability of the floodlight body 200 when rotating.
