Description

Technical Field

[0001] This utility model belongs to the field of floodlights, specifically, it relates to a portable LED floodlight. Background Technology

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

[0003] Patent application CN210979484U discloses a portable LED floodlight. Paragraph 0024 of the specification describes a sliding rod and a sliding sleeve. The sliding rod can move up and down flexibly within the sliding sleeve, facilitating the positioning of a U-shaped rod by engaging the sliding rod with a limiting hole. A pull ring is fixedly connected to the top of the sliding rod, and a spring is sleeved on the surface of the sliding rod. The bottom end of the spring is fixedly connected to the upper surface of the connecting plate, and the top end of the spring is fixedly connected to the lower surface of the pull ring. By setting the spring, the sliding rod can be stably engaged in the limiting hole under the action of the spring tension, preventing the sliding rod from disengaging from the limiting hole, thereby ensuring that the U-shaped rod is stably fixed on the base.

[0004] However, in actual use, the pull ring, under the action of the spring, causes one end of the slide rod to slide into the inside of the limiting hole. Because the spring repeatedly stretches and shortens when subjected to vibration and impact, one end of the slide rod will slide out of the limiting hole under the action of the spring elasticity, thus failing to guarantee the stability of the U-shaped rod on the upper side of the base.

[0005] To address these shortcomings, a portable LED floodlight is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a portable LED floodlight.

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

[0008] A portable LED floodlight includes a U-shaped plate. Two support plates are slidably fitted on one side of the U-shaped plate, and a floodlight body is fixedly fitted between the two support plates. A U-shaped column is elastically and slidably fitted on one side of the support plate, and a connecting plate is fixedly fitted on one side of the U-shaped column. A positioning rod is fixedly fitted at the bottom of the connecting plate, and one end of the positioning rod is engaged with one side of the U-shaped plate. A threaded rod is threaded on the upper side of the connecting plate, and a positioning disc is rotatably fitted at one end of the threaded rod. One side of the positioning disc engages with one side of the support plate.

[0009] Optionally, one side of the U-shaped plate is provided with a placement groove, two first guide grooves, and a plurality of positioning holes connected to the placement groove, and one end of the positioning rod is engaged with the positioning hole.

[0010] Optionally, a sliding plate is fixedly fitted between the two support plates, and one end of the sliding plate is slidably fitted inside the first guide groove.

[0011] Optionally, two second guide grooves are provided on one side of the support plate, and guide rods are fixedly fitted inside the second guide grooves.

[0012] Optionally, one end of the U-shaped post is slidably fitted inside the second guide groove, and guide holes are provided at both ends of the U-shaped post. The guide rod is located inside the guide hole, and a spring is fixedly fitted between the side wall of the second guide groove and one side of the U-shaped post. The spring is sleeved on the periphery of the guide rod.

[0013] Optionally, a fixing block is fixedly fitted on the upper side of the connecting plate, and a threaded hole is provided on one side of the fixing block, which is threadedly engaged with the threaded rod.

[0014] Optionally, one end of the threaded rod is fixedly fitted with a rotating disk, and the other end of the threaded rod is fixedly fitted with a T-shaped rod.

[0015] Optionally, a T-shaped hole is provided on one side of the positioning disk, and the T-shaped rod is rotatably fitted inside the T-shaped hole.

[0016] 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:

[0017] The positioning rod is designed so that the connecting plate, under the action of the U-shaped column, drives the positioning rod to slide towards the U-shaped plate, and the floodlight body is positioned on the upper side of the U-shaped plate through one end of the positioning rod. This reduces the problem in the prior art where one end of the sliding rod slides out of the limiting hole under the action of the spring elasticity, making the process of fixing the floodlight body more convenient.

[0018] The second guide groove is designed to allow one end of the U-shaped column to slide inside the second guide groove under the action of the worker. The second guide groove guides the sliding direction of the U-shaped column, reducing the problem of tilting when the U-shaped column slides and improving the stability of the U-shaped column when sliding.

[0031] Working principle:

[0032] First, place the support plate 201 on the upper side of the U-shaped plate 100, and then slide the U-shaped column 204 downward. The U-shaped column 204 drives one end of the guide rod 205 to be positioned inside the U-shaped plate 100. Then rotate the threaded rod 212. The threaded rod 212 drives the positioning plate 215 to slide towards the support plate 201. Under the action of the threaded rod 212, the positioning plate 215 is positioned on one side of the support plate 201, thereby completing the fixation of the floodlight body 202.

[0033] The positioning rod 210 is designed so that the connecting plate 208, under the action of the U-shaped column 204, drives the positioning rod 210 to slide towards the U-shaped plate 100. One end of the positioning rod 210 positions the floodlight body 202 on the upper side of the U-shaped plate 100, which reduces the problem in the prior art where one end of the slide rod slides out of the limiting hole under the action of the spring elasticity, making the process of fixing the floodlight body 202 more convenient.

[0034] To make the sliding process of the U-shaped column 204 on one side of the support plate 201 more stable in this embodiment, the following structural improvements are made, such as...

[0035] In this embodiment, the support plate 201 is first slid, and one end of the sliding plate 200 is slid into the first guide groove 103. Then, the U-shaped column 204 is slid down, and one end of the U-shaped column 204 slides inside the second guide groove 203. The U-shaped column 204 slides around the guide rod 205 through the guide hole 207 and stretches the spring 206. The U-shaped column 204 drives one end of the positioning rod 210 to slide into the positioning hole 102 through the connecting plate 208. Then, the rotating disk 213 is rotated, and the rotating disk 213 drives the positioning disk 215 to slide towards the support plate 201 through the threaded rod 212. The support plate 201 is positioned by one side of the positioning disk 215.

[0036] The second guide groove 203 is provided so that one end of the U-shaped column 204 can slide inside the second guide groove 203 under the action of the operator, and the sliding direction of the U-shaped column 204 is guided by the second guide groove 203, which reduces the problem of tilting of the U-shaped column 204 during sliding and improves the stability of the U-shaped column 204 during sliding.
