Description

Technical Field

[0001] This utility model belongs to the field of public safety facilities technology, and in particular relates to a rotatable emergency sign. Background Technology

[0002] In crowded public places such as shopping malls, hotels, office buildings, and hospitals, rotating emergency signs are crucial facilities for ensuring safe evacuation. They also fall under the category of safety signage, enhancing visibility and guidance through a dynamic rotating display to help people quickly find safe exits in emergencies.

[0003] Existing equipment has drawbacks such as a small footprint, increasing the risk of tipping over, which can damage the equipment and shorten its lifespan. Furthermore, the height of the sign is difficult to adjust to the environment, making it hard for personnel to see. Replacing the sign is also complicated. Therefore, we propose a rotatable emergency sign. Utility Model Content

[0004] The purpose of this utility model is to provide a rotatable emergency sign. By using support legs and threaded rods, it solves the problems of small footprint, increased risk of equipment tipping, equipment damage and reduced service life when the equipment is tipped over, inconvenience in adjusting the height of the sign according to the environment, difficulty in seeing the sign, and complicated replacement operation when changing the sign.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a rotatable emergency sign, including a base, and a sleeve is fixedly connected to the top outer wall of the base;

[0007] The inner wall of the sleeve is provided with an adjustment mechanism, which includes a threaded tube. The outer wall of the threaded tube is rotatably connected to the inner wall of the sleeve. Several handles are fixedly connected to the outer wall of the threaded tube. A threaded rod is threadedly connected to the inner wall of the threaded tube. Several grooves are formed on the inner wall of the threaded rod. Several rings are slidably connected to the outer wall of the threaded rod. Each of the rings has a circular groove on its inner wall. An indicator plate is fixedly connected to the outer wall of each ring. A support plate is fixedly connected to the outer wall of each support plate. A sliding groove is formed on the inner wall of each support plate. A sliding rod is slidably connected to the inner wall of each sliding groove. A spring is sleeved on the outer wall of each sliding rod. A limit rod is threadedly connected to the inner wall of the threaded rod. A stabilizing mechanism is provided on the outer wall of the sleeve.

[0008] The above technical solution limits the sliding rod by using a support rod, preventing displacement during the sliding rod's movement.

[0009] Furthermore, the stabilizing mechanism includes several mounting plates, the outer walls of which are fixedly connected to the outer wall of the sleeve.

[0010] The above technical solution fixes the threaded rod two in place with the mounting plate, preventing it from shaking when it rotates.

[0011] Furthermore, a threaded rod is rotatably connected to the inner wall of the mounting plate, and a turntable is fixedly connected to the outer wall of the threaded rod near the limiting rod.

[0012] With the above technical solution, when the turntable rotates, it will cause the threaded rod two to rotate, and then the threaded rod two will move with the fixed plate.

[0013] Furthermore, a fixed plate is threadedly connected to the outer wall of the threaded rod II, and a movable ring is slidably connected to the outer wall of the sleeve.

[0014] With the above technical solution, the moving ring will move along with the fixed plate when it moves, and then the moving ring will move horizontally on the sleeve.

[0015] Furthermore, the outer wall of the movable ring is fixedly connected to the outer wall of the fixed plate, and a number of joint shafts are fixedly connected to the outer wall of the movable ring. Each of the joint shafts is rotatably connected to a connecting rod.

[0016] With the above technical solution, the moving ring moves along with the joint axis, and then the joint axis moves along with the connecting rod.

[0017] Furthermore, the inner wall of the base is provided with several square grooves, and the inner wall of each of the square grooves is fixedly connected with a rotating shaft.

[0018] The above technical solution limits the support leg by using a rotating shaft, preventing displacement when the support leg rotates.

[0019] Furthermore, the outer walls of several of the rotating shafts are rotatably connected to support legs, and the inner walls of several of the support legs are provided with limit grooves.

[0020] The above technical solution increases the footprint when the support legs are extended, making the equipment more stable during use.

[0021] Furthermore, a rotating rod is fixedly connected to the inner wall of each of the limiting grooves, the outer wall of each of the rotating rods is rotatably connected to the inner wall of each of the connecting rods, and an anti-slip pad is fixedly connected to the outer wall of each of the supporting legs.

[0022] The above technical solution increases the friction between the support legs and the ground by using anti-slip pads, preventing the equipment from slipping during use.

[0023] This utility model has the following beneficial effects:

[0024] 1. This utility model incorporates a support leg. When the fixed plate moves, the moving ring moves along with it, which in turn moves the joint shaft. As the joint shaft moves, the connecting rod moves, which in turn moves the rotating rod. As the rotating rod moves, the support leg also moves. Simultaneously, the support leg rotates on the rotating shaft and then unfolds, improving the stability of the equipment, increasing its floor space, reducing the risk of tipping, preventing damage caused by tilting, and extending the equipment's lifespan.

[0025] 2. This utility model incorporates a threaded rod. When the threaded tube rotates, the threaded rod moves along with it, and then the threaded rod moves along with the ring. Simultaneously, the indicator sign moves with the ring, facilitating adjustment of the appropriate height. Furthermore, pulling the sliding rod compresses the spring, causing the sliding rod to disengage from the slot and the circular groove. This allows the ring to rotate, improving the equipment's flexibility. The height of the indicator sign can be adjusted according to different usage environments, making it easy for personnel to quickly see the sign. It also makes replacing the indicator sign more convenient and faster.

[0026] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figure 1-5As shown, this utility model is a rotatable emergency sign, including a base 1. A sleeve 101 is fixedly connected to the top outer wall of the base 1. The sleeve 101 is fixed above the base 1 to reduce the possibility of shaking during use. An adjustment mechanism 2 is provided on the inner wall of the sleeve 101. The adjustment mechanism 2 includes a threaded tube 201. The outer wall of the threaded tube 201 is rotatably connected to the inner wall of the sleeve 101. Several handles 202 are fixedly connected to the outer wall of the threaded tube 201. When the handles 202 are rotated, the threaded tube 201 will rotate, and then the threaded tube 201 will move the threaded rod 203, which is convenient for the operator to move the threaded rod 203. The inner wall of the threaded tube 201 is threadedly connected to the threaded rod 203. Several slots 204 are opened on the inner wall of the threaded rod 203. Several rings 205 are slidably connected to the outer wall of the threaded rod 203. The inner walls of the rings 205 are all A circular groove 206 is provided. When the threaded rod 203 moves, it will move the ring 205, and then the ring 205 will move the indicator 207, which can be adjusted for height. The indicator 207 is fixedly connected to the outer wall of several rings 205. The support plate 208 is fixedly connected to the outer wall of several rings 205. The inner wall of several support plates 208 is provided with a sliding groove 209. The sliding rod 210 slides in the support plate 208. There is no displacement when the sliding rod 210 slides. The inner wall of several sliding grooves 209 is slidably connected to the sliding rod 210. The outer wall of several sliding rods 210 is fitted with a spring 211. The inner wall of the threaded rod 203 is threadedly connected with a limit rod 212. The outer wall of the sleeve 101 is provided with a stabilizing mechanism 3. The surface of the sliding rod 210 has a spring 211. There is no misalignment when the spring 211 is compressed.

[0037] When the throttle 202 is turned, the threaded tube 201 will rotate, and then the threaded tube 201 will move the threaded rod 203. When the threaded rod 203 moves, the ring 205 will move, and then the indicator 207 will move with the ring 205. Then the slide rod 210 can be pulled. When the slide rod 210 moves, it will compress the spring 211, and then the slide rod 210 will disengage from the slot 204 and the groove 206, so that the ring 205 can rotate. Then the direction of the indicator 207 can be adjusted to make it easier to adjust the appropriate height and make the indicator 207 easier to see.

[0038] The stabilizing mechanism 3 includes several mounting plates 301. The outer walls of the mounting plates 301 are fixedly connected to the outer wall of the sleeve 101. The threaded rod 302 rotates within the mounting plates 301, making the rotation more stable. The inner wall of the mounting plates 301 is rotatably connected to the threaded rod 302. A turntable 303 is fixedly connected to the outer wall of the threaded rod 302 near the limit rod 212. When the turntable 303 rotates, it will cause the threaded rod 302 to rotate. Then, the threaded rod 302 will cause the fixed plate 304 to rotate, realizing the kinetic energy transfer between the parts. The outer wall of the threaded rod 302 is threadedly connected to the fixed plate 304. The outer wall of the sleeve 101 is slidably connected to the moving ring 305. When the fixed plate 304 moves, it will cause the moving ring 305 to move. Then, the moving ring 305 will cause the joint shaft 306 to move.

[0039] When the turntable 303 rotates, it drives the threaded rod 302 to rotate. Then the threaded rod 302 rotates in the mounting plate 301. When the threaded rod 302 rotates, it drives the fixed plate 304 to move. Then the fixed plate 304 drives the moving ring 305 to move. At the same time, the joint shaft 306 moves with the moving ring 305, realizing the kinetic energy transfer between multiple parts. When one part moves, other parts will also move.

[0040] The outer wall of the movable ring 305 is fixedly connected to the outer wall of the fixed plate 304. Several joint shafts 306 are fixedly connected to the outer wall of the movable ring 305. Each joint shaft 306 has a connecting rod 307 rotatably connected to its outer wall. When the joint shaft 306 moves, it carries the connecting rod 307. During the movement of the connecting rod 307, it rotates on the joint shaft 306 to prevent displacement. Several square grooves 308 are formed on the inner wall of the base 1. Each square groove 308 has a rotating shaft 309 fixedly connected to its inner wall. Each rotating shaft 309 has a supporting leg 310 rotatably connected to its outer wall. Each support leg 310 has a limiting groove 311 on its inner wall. A rotating rod 312 is fixedly connected to the inner wall of several limiting grooves 311. When the connecting rod 307 moves, it will move the rotating rod 312, and then the rotating rod 312 will move the support leg 310, causing the support leg 310 to unfold and increase the floor space. The outer walls of several rotating rods 312 are rotatably connected to the inner walls of several connecting rods 307. Anti-slip pads 313 are fixedly connected to the outer walls of several support legs 310. When the support leg 310 unfolds, the anti-slip pads 313 will be in contact with the ground, and then the anti-slip pads 313 will increase the friction and prevent the equipment from slipping.

[0041] When the joint axis 306 moves, it will move the connecting rod 307. Then the connecting rod 307 will move the rotating rod 312. When the rotating rod 312 moves, it will move the supporting leg 310. Then the supporting leg 310 will rotate on the rotating shaft 309. At the same time, the supporting leg 310 will unfold. When unfolded, the anti-slip pad 313 will be in contact with the ground to prevent the equipment from slipping during use and increase friction.

[0042] One specific application of this embodiment is:

[0043] When the operator needs to use the equipment, first rotate the turntable 303. As the turntable 303 rotates, the threaded rod 302 also rotates, causing the fixed plate 304 to move. As the fixed plate 304 moves, the moving ring 305 moves, causing the joint shaft 306 to move. As the joint shaft 306 moves, the connecting rod 307 moves, causing the rotating rod 312 to move. As the rotating rod 312 moves, the support leg 310 also moves, rotating on the rotating shaft 309. The support leg 310 then unfolds, and when unfolded, the anti-slip pad 313 adheres to the ground to prevent the equipment from sliding and to increase its floor space. During use, the handle 202 can be rotated, causing the threaded tube 201 to rotate. When in motion, the threaded rod 203 moves, and then the threaded rod 203 moves the ring 205. At the same time, the indicator 207 moves with the ring 205, making it easy to adjust to a suitable height. Simultaneously, the slide rod 210 can be pulled. When the slide rod 210 is pulled, the spring 211 is compressed, causing the slide rod 210 to disengage from the slot 204 and the circular groove 206. Then, the ring 205 can be rotated, causing the indicator 207 to rotate as well. After adjusting to a suitable position, the slide rod 210 is released, and then the spring 211 compresses the slide rod 210, causing the slide rod 210 to engage with the slot 204 and the circular groove 206, preventing the indicator 207 from rotating on its own. At the same time, the limit rod 212 can be unscrewed from the threaded rod 203, and then the slide rod 210 can be pulled. When the slide rod 210 is pulled out, the ring 205 can be removed from the threaded rod 203, making it easy to replace different indicator 207s.
