[0015] In summary, the present invention has the following main beneficial effects:

[0016] 1.

When impacted, the protective plates push the two sets of second sliders to compress the return spring, and the two sets of second sliders compress the damper through two sets of sliding sleeves, so that the impact force is buffered and the damage to the portable signal light is reduced during impact.

[0017] 2. This invention uses two sets of No. 1 sliders to drive two sets of racks to move when they approach each other. This causes the racks to drive the gears to rotate, which in turn pushes the support frame downwards. This allows the support legs to slide down out of the outer shell and support the ground. This allows the portable signal light to be moved conveniently via pulleys. When the portable signal light is moved to the designated position, it is supported on the ground by the support legs, preventing the pulleys from contacting the ground. This ensures that the portable signal light can be placed stably on the ground without accidentally sliding.

[0018] 3. This invention uses the Liangzhu slider to push the two sets of No. 1 pistons closer together, which in turn pushes air into the support tube, causing the No. 2 piston to slide upwards. This causes the sliding rod to extend out of the support tube, thereby raising the height of the signal light body for easier driver observation. When moving the portable signal light, the sliding rod can automatically slide into the support tube, making it more convenient to move or transport the portable signal light.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0030] The embodiments of the present invention will now be described.

[0031] A portable traffic signal device, such as Figures 1-7 As shown, it includes an outer shell 1, a protective mechanism 2 is provided on the inner wall of the outer shell 1, multiple sets of pulleys 3 are rotatably connected to the bottom end of the outer shell 1, a support mechanism 4 is slidably provided on the bottom end of the inner wall of the outer shell 1, the support mechanism 4 is fixedly connected to the bottom end of the protective mechanism 2, and an extension mechanism 5 extending into the interior of the outer shell 1 is provided on the top end of the outer shell 1.

[0032] The protective mechanism 2 includes a bidirectional threaded rod 201, a first slider 202, a top rod 203, a push plate 204, a support rod 205, a second slider 206, a connecting rod 207, a protective plate 208, and a return spring 209. A set of bidirectional threaded rods 201 extending to the outside of the outer shell 1 are rotatably connected to the inner wall of the outer shell 1. Two sets of first sliders 202 located inside the outer shell 1 are threadedly connected to the outer wall of the bidirectional threaded rods 201. One end of each of the two sets of first sliders 202 is hinged to the side wall of each set of first sliders 202. The other end of each of the two sets of top rods 203 on the same side is hinged to a push plate 204. A support rod 205 is fixedly connected to the side wall of the push plate 204. Two sets of second sliders 206 are slidably connected to the outer wall of the support rod 205. The side walls of the two sets of connecting rods 207 are respectively hinged to one end, and the other ends of the two sets of connecting rods 207 are hinged to protective plates 208. The outer wall of the support rod 205 is fitted with a return spring 209. The two ends of the return spring 209 are respectively fixedly connected to the side wall of a set of second sliders 206. The support rod 205 includes a guide rod 2051, a sliding sleeve 2052 and a damper 2053. The two sets of guide rods 2051 are fixedly connected to the side wall of the push plate 204. The two sets of second sliders 206 are respectively slidably fitted on the outer wall of the guide rod 2051. One end of the two sets of guide rods 2051 is respectively slidably fitted with a sliding sleeve 2052. The two sets of sliding sleeves 2052 respectively abut against the side wall of the set of second sliders 206. The damper 2053 is fixedly connected between the two sets of sliding sleeves 2052.

[0033] By rotating the bidirectional threaded rod 201, the bidirectional threaded rod 201 pushes the two sets of first sliders 202 closer together, thereby causing the two sets of first sliders 202 to push the two sets of push rods 203 respectively. The two sets of push rods 203 push the push plate 204 to slide on the inner wall of the outer shell 1, thereby causing the push plate 204 to push the support rod 205 to move. The support rod 205 pushes the protective plate 208 out of the outer shell 1 through the connecting rod 207. When impacted, the protective plate 208 transmits the impact force to the connecting rod 207, thereby causing the connecting rod 207 to push the two sets of second sliders 206 closer together. The slider 206 compresses the return spring 209, and the two sets of second sliders 206 push the two sets of sliding sleeves 2052 closer to each other, thereby causing the two sets of sliding sleeves 2052 to compress the damping rod, thus buffering the impact force. After the impact, the return spring 209 rebounds and pushes the two sets of second sliders 206 to reset, thereby resetting the protective plate 208. By rotating the bidirectional threaded rod 201 in the opposite direction, the two sets of first sliders 202 move away from each other, causing the two sets of push plates 204 to move in the opposite direction. At this time, the push plate 204 drives the support rod 205 to move in the opposite direction, thereby causing the protective plate 208 to slide into the interior of the outer shell 1.

[0034] Please refer to this carefully. Figures 1-7The support mechanism 4 includes a rotating rod 401, a connecting frame 402, a spiral groove 403, a protrusion 404, a support leg 405, a gear 406, and a rack 407. The rotating rod 401 is rotatably connected to the bottom of the inner wall of the outer shell 1. The connecting frame 402 is slidably sleeved on the outer wall of the rotating rod 401. The spiral groove 403 is formed on the outer wall of the rotating rod 401. Two sets of protrusions 404 extending into the spiral groove 403 are fixedly connected to the inner wall of the connecting frame 402. Multiple sets of support legs 405 are fixedly connected to the outer wall of the connecting frame 402. The multiple sets of support legs 405 are slidably connected to the bottom of the inner wall of the outer shell 1. The top of the rotating rod 401 is fixedly connected to the gear 406. The bottom of the two sets of first sliders 202 are respectively fixedly connected to a set of racks 407. The two sets of racks 407 are located on both sides of the gear 406, and the two sets of racks 407 mesh with the gear 406 simultaneously.

[0035] When the two sets of sliders 202 approach each other, they drive the two sets of racks 407 to move, causing the racks 407 to push the gears 406 to rotate. During the rotation of the gears 406, the shaft rotates, and the shaft pushes the protrusion 404 downward through the spiral groove 403. The protrusion 404 drives the connecting block downward, causing multiple sets of support legs 405 to extend out of the outer shell 1 and support the ground. At this time, the pulley 3 is disengaged from the ground. When the two sets of sliders move away from each other, the racks 407 move in opposite directions, and the gears 406 rotate in opposite directions, causing the rotating rod 401 to rotate in opposite directions. At this time, the protrusion 404 moves upward, driving the connecting frame 402 to move upward, so that multiple sets of support legs 405 slide into the outer shell 1, thus allowing the pulley 3 to support the ground, making it more convenient to move the portable signal light.

[0036] Please refer to this carefully. Figures 1-7 The extension mechanism 5 includes a sleeve 501, a first piston 502, a push rod 503, a support tube 504, a second piston 505, a slide rod 506, and a signal light body 507. The sleeve 501 is fixedly connected to the top of the inner wall of the outer casing 1. Two sets of first pistons 502 are slidably connected to the inner wall of the sleeve 501. One end of a push rod 503 extending to the outside of the sleeve 501 is fixedly connected to the side wall of each of the two sets of first pistons 502. The other end is fixedly connected to the top of a set of first sliders 202. The top of the outer shell 1 is fixedly connected to a support tube 504. The top of the sleeve 501 is connected to the support tube 504. The inner wall of the support tube 504 is slidably connected to a second piston 505. The top of the second piston 505 is fixedly connected to a set of slide rods 506 extending to the outside of the support tube 504. The end of the slide rod 506 located outside the support tube 504 is fixedly connected to a signal light body 507.

[0037] When the two sets of sliders 202 move closer together, they push the two sets of push rods 503 closer together. The two sets of push rods 503 push the two sets of pistons 502 closer together. The two sets of pistons 502 push the air inside the sleeve 501 into the support tube 504, causing the piston 505 to slide upward. The piston 505 pushes the slide rod 506 to slide out of the sleeve 501, causing the slide rod 506 to raise the height of the signal light body 507, making it easier for the driver to see the signal light. When the two sets of sliders 202 move away from each other, they also cause the two sets of pistons 502 to move away from each other, causing the air inside the support tube 504 to be drawn out. This causes the piston 505 to move downward, causing the slide rod 506 to slide into the support tube 504, thus lowering the height of the signal light body 507 for easier transportation and handling.

[0038] In use, when using the traffic light, rotating the bidirectional threaded rod 201 causes the two sets of first sliders 202 to move closer to each other, thereby causing the two sets of protective plates 208 to extend outside the outer shell 1. When impacted, the protective plates 208 push the two sets of second sliders 206 to compress the return spring 209, and the two sets of second sliders 206 compress the damper 2053 through the two sets of sliding sleeves 2052, so that the impact force is buffered and the damage to the portable traffic light is reduced during impact.
