[0034] The anti-theft floodlight provided by the present utility model will now be described.

[0035] Please refer to Figure 1 together. The anti-theft floodlight includes a floodlight body 1, a mounting base 2, a plurality of limiting mechanisms 3 and an alarm mechanism 4. Among them, the mounting base 2 is placed on the ground, and the floodlight body 1 is rotatably arranged on the mounting base 2. A plurality of limiting holes are provided on the mounting base 2. The plurality of limiting mechanisms 3 correspond to the limiting holes one by one. The limiting mechanism 3 is inserted into the corresponding limiting hole, and the limiting mechanism 3 is inserted into the soil. The alarm mechanism 4 is arranged on the mounting base 2, and a detection component 410 is connected to the alarm device 402. When the detection component 410 detects that the mounting base 2 is lifted, the alarm mechanism 4 gives an alarm.

[0036] The beneficial effects of the anti-theft floodlight provided in this embodiment are as follows: Compared with the prior art, the anti-theft floodlight provided in this embodiment fixes the mounting base 2 on the ground by setting the limiting holes and the limiting mechanism 3. At the same time, since the floodlight body 1 is arranged on the mounting base 2, the limiting holes and the limiting mechanism 3 also fix the floodlight body 1. By setting the alarm mechanism 4 and the detection component 410, an alarm is given when the mounting base 2 is lifted, preventing someone from violently removing the limiting mechanism 3 and stealing the floodlight body 1 and the mounting base 2, greatly increasing the safety of placing the floodlight body 1.

[0037] As Figure 2 and Figure 3 shown, the alarm mechanism 4 includes a sealed box 401, an alarm device 402, a storage battery 403 and a wire 404. The alarm device 402 and the storage battery 403 are connected by the wire 404 to form an alarm circuit. The alarm circuit is arranged in the sealed box 401. The sealed box 401 is arranged on the mounting base 2. The alarm circuit is open, and both ends of the wire 404 at the open circuit of the alarm circuit include a first break point 405 and a second break point 406. As long as the first break point 405 and the second break point 406 are not conducting, the alarm device 402 will not give an alarm.

[0038] In this embodiment, the detection component 410 includes a conductive plate 407, a telescopic rod 408, and a driving plate 409. The conductive plate 407 is slidably disposed in the sealed box 401. The telescopic rod 408 is disposed at the bottom of the conductive plate 407. A first telescopic hole is provided on the mounting base 2, and a second telescopic hole is provided at the bottom of the sealed box 401. The telescopic rod 408 passes through the first telescopic hole and the second telescopic hole and extends downward below the mounting base 2. The driving plate 409 is disposed at the bottom end of the telescopic rod 408. When the mounting base 2 is placed on the ground, the driving plate 409 contacts the ground first. Subsequently, the driving plate 409 abuts against the mounting base 2. At this time, the conductive plate 407 is disposed above the first break point 405 and the second break point 406, such that the first break point 405 and the second break point 406 are not electrically connected, and the alarm device 402 does not alarm. However, once the mounting base 2 is lifted, the driving plate 409 slides downward, driving the conductive plate 407 to slide downward until the conductive plate 407 abuts against the bottom plate of the sealed box 401. At this time, the conductive plate 407 is connected to the first break point 405 and the second break point 406, the alarm circuit is closed, and the alarm device 402 starts to alarm. The alarm device 402 in this embodiment may adopt an audible and visual alarm device 402, and the sealed box 401 may be made of a transparent material.

[0039] To prevent the bottom of the mounting base 2 from being uneven when the driving plate 409 abuts against the bottom of the mounting base 2, a relief groove 201 is provided at the bottom of the mounting base 2. The depth of the relief groove 201 is not less than the thickness of the driving plate 409. When the mounting base 2 is placed on the ground, the driving plate 409 is received in the relief groove 201.

[0040] As Figure 4 and Figure 6 shown, the limiting mechanism 3 includes a limiting cylinder 301. The bottom of the limiting cylinder 301 is conical. There is a limiting ring 302 on the top of the limiting cylinder 301. When the limiting cylinder 301 is inserted into the limiting hole, the limiting ring 302 abuts against the mounting base 2. The bottom of the limiting cylinder 301 is set to be conical, which is convenient for the limiting cylinder 301t to be inserted into the soil. The setting of the limiting ring 302 enables the mounting base 2 not to be lifted upward after the limiting cylinder is inserted into the soil, realizing the fixation of the mounting base 2.

[0041] As a preferred technical solution, a plurality of through holes 304 are provided on the side wall of the limiting cylinder 301. An anti-pulling plate 303 is inserted in the through holes 304. An installation groove 305 is provided on one side of the through holes 304. An installation plate 307 is provided on the anti-pulling plate 303. A spring 306 is provided between the installation plate 307 and the side wall of the installation groove 305.

[0042] As Figure 4 、 Figure 5 and Figure 6As shown, when the spring 306 is in its natural state, the outer end of the anti-pulling plate 303 is flush with the outer wall of the limit cylinder 301. The inner end of the anti-pulling plate 303 is arranged inside the inner hole of the limit cylinder 301, and the inner ends of the anti-pulling plates 303 are arranged at intervals. A driving rod 308 is inserted into the limit cylinder 301. The side wall of the driving rod 308 abuts against the inner wall of the limit cylinder 301. A driving cone is provided at the bottom end of the driving rod 308, and the driving rod 308 can push the anti-pulling plate 303 to slide out of the limit cylinder 301 due to downward sliding. The setting of the anti-pulling plate 303 can increase the force required to pull out the limit cylinder 301, prevent the pulling out of the limit plate, and play a role in anti-theft of the mounting seat 2.

[0043] As Figure 4 shown, the cross-section of the limit cylinder 301 is square, the cross-section of the inner hole of the limit cylinder 301 is square, the inner hole of the limit ring 302 is square, and the side length of the inner hole of the limit ring 302 is smaller than the side length of the inner hole of the limit cylinder 301. A push rod 309 is provided at the top of the driving rod 308. The side length of the cross-section of the push rod 309 is the same as the side length of the inner hole of the limit ring 302, so that the driving rod 308 cannot be pulled out from the inner hole of the limit ring 302, preventing the loss of the driving rod 308 and resulting in the inoperability of the limit mechanism 3.

[0044] It should be noted that a breaking knife 310 is provided at the outer end of the anti-pulling plate 303. The setting of the breaking knife 310 can reduce the resistance suffered by the anti-pulling plate 303 during the process of inserting into the soil.

[0045] In addition, as Figure 7 shown, the width of the installation groove 305 is smaller than the width of the through hole 304, so that the anti-pulling plate 303 will not enter the installation groove 305, preventing the side walls on both sides of the installation groove 305 from blocking the anti-pulling plate 303 from protruding.

[0046] As a preferred technical solution, the push rod 309 is made of a magnetic material. When the bottom end of the driving rod 308 abuts against the bottom end of the inner hole of the limit cylinder 301, the top end of the push rod 309 is flush with the top end of the limit ring 302, so that the push rod 309 cannot be easily pulled out and can only be pulled out upward by using a permanent magnet to attract the push rod 309, realizing the retraction of the anti-pulling plate 303, and further enabling the limit cylinder 301 to be pulled out.

[0047] Finally, a receiving groove 311 is provided on the side wall of the inner hole of the limiting cylinder 301. A baffle 312 is rotatably provided in the receiving groove 311. A torsion spring is provided between the baffle 312 and the receiving groove 311. When the torsion spring is in a natural state, the baffle 312 is horizontally arranged, and the baffle 312 can be received in the receiving groove 311 due to rotation. The force required to flip the baffle 312 is greater than the force required to insert the limiting cylinder 301 into the soil. During use, an external force acts on the push rod 309, and the push rod 309 acts on the baffle 312 to insert the limiting cylinder 301 into the soil. Until the limiting ring 302 abuts against the mounting seat 2, when the external force continues to act and increases, it will push the baffle 312 to flip, and the driving rod 308 extends below the baffle 312.

[0048] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
