[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figures 1 to 4 The road traffic engineering warning device shown includes a base 1. A vertical telescopic rod 2 is fixed to the top of the base 1. A first locking component is installed on the telescopic rod 2 for positioning and locking with the telescopic end after it has extended or retracted.

[0021] Specifically, the first snap-fit ​​assembly includes a U-shaped seat 3, which is fixed to the non-telescopic end of the telescopic rod 2. The two distal ends of the U-shaped seat 3 are arranged horizontally, and a first rotating shaft 4 is horizontally placed between the two distal ends of the U-shaped seat 3. The first rotating shaft 4 is spatially perpendicular to the telescopic rod 2 and rotatably connected to the two distal ends of the U-shaped seat 3.

[0022] A first torsion spring is fitted onto the first rotating shaft 4. One end of the first torsion spring is fixedly connected to the U-shaped seat 3, and the other end of the first torsion spring is fixedly connected to the first rotating shaft 4. A spiral frame 6 and a lever 5 are fixedly mounted on the first rotating shaft 4. The lever 5 is used to drive the first rotating shaft 4 to rotate.

[0023] Two first insert rods 7 are slidably mounted on the upper limit of the non-telescopic end of the telescopic rod 2. The two first insert rods 7 are parallel and perpendicular to the telescopic rod 2 and the first rotating shaft 4. One end of each of the two first insert rods 7 is inserted into the non-telescopic end of the telescopic rod 2. Multiple first slots are provided on the telescopic end of the telescopic rod 2 to engage and limit the insertion of the two first insert rods 7. The multiple first slots are divided into two groups, and the first slots in the same group are evenly spaced vertically. The two groups of first slots correspond one-to-one with the two first insert rods 7.

[0024] A drive shaft 8 is fixedly installed between the two first insertion rods 7 at their ends outside the telescopic rod 2. The drive shaft 8 is parallel to the first rotating shaft 4, passes through the loop frame 6, and is in transmission cooperation with the loop frame 6.

[0025] The telescopic end of the telescopic pole 2 is vertically upward and fixedly connected to the fixing plate 9, which is vertically positioned. A warning light assembly is fixedly installed on the front end face of the fixing plate 9.

[0026] A microcomputer system is installed inside the fixed plate 9, and the warning light group is electrically connected to the microcomputer system.

[0027] The fixed plate 9 has two mounting slots inside, which are symmetrically arranged and have horizontal openings facing away from each other. An extension plate 10 is slidably installed in each mounting slot.

[0028] A display screen 11 is fixedly installed on the front end face of each extension plate 10, and each display screen 11 is electrically connected to the microcomputer system.

[0029] Each extension plate 10 is equipped with a second snap-fit ​​component for positioning and securing with the fixing plate 9 after sliding in and out of it.

[0030] Specifically, the second snap-fit ​​assembly includes a second rotating shaft 12. An equipment cavity is formed within the extension plate 10, and the second rotating shaft 12 is horizontally positioned within the equipment cavity along the sliding direction of the extension plate 10 and is rotatably connected to the extension plate 10. A second torsion spring is sleeved on the second rotating shaft 12, with one end of the second torsion spring fixedly connected to the extension plate 10 and the other end of the second torsion spring fixedly connected to the second rotating shaft 12.

[0031] A push rod 13 is fixedly mounted on the second rotating shaft 12, and the push rod 13 intersects the second rotating shaft 12 in a cross shape. Two vertically slidable second insertion rods 14 are installed inside the equipment cavity, with the two second insertion rods 14 positioned vertically opposite each other. The two ends of the push rod 13 away from the second rotating shaft 12 correspond one-to-one with the two second insertion rods 14, and a hinge rod 15 is hinged between each of the two ends of the push rod 13 away from the second rotating shaft 12 and the corresponding second insertion rod 14.

[0032] The ends of the two second insert rods 14 that are far apart both penetrate the extension plate 10 and are slidably engaged with the extension plate 10. Two second slots are provided on the top and bottom inner walls of the mounting groove to be inserted and engaged with the corresponding second insert rods 14. The two second slots located on the same inner wall of the mounting groove are arranged one in front of the other along the sliding direction of the extension plate 10.

[0033] The end of the second rotating shaft 12 away from the bottom of the mounting groove extends out of the extension plate 10, and a knob is coaxially fixed on the end of the second rotating shaft 12 extending out of the extension plate 10.

[0034] Working principle: When this warning device is needed on a highway or during a sudden traffic situation, the fixed plate 9 is raised and the two extension plates 10 are pulled out according to the situation on site.

[0035] The process of raising the fixed plate 9 is as follows: The lever 5 is moved, causing the first rotating shaft 4 to rotate. The first rotating shaft 4 causes the retaining frame 6 to rotate away from the telescopic rod 2 and twist the first torsion spring. The retaining frame 6 pushes the transmission shaft 8 away from the telescopic rod 2, and the transmission shaft 8 causes the two first inserts 7 to disengage from their respective first slots. Next, the fixed plate 9 is pushed upwards, causing the telescopic end of the telescopic rod 2 to extend upwards. When the fixed plate 9 reaches the appropriate height, the lever 5 is released, and the fixed plate 9 is pushed up and down. At this time, under the elastic force of the first torsion spring, the first rotating shaft 4 reverses direction and causes the retaining frame 6 to rotate back. The retaining frame 6 pushes the transmission shaft 8 closer to the telescopic rod 2, and the transmission shaft 8 causes the first inserts 7 to abut against the telescopic end of the telescopic rod 2. During the up-and-down pushing of the fixed plate 9, the first slot corresponds to the corresponding first insert 7. Under the elastic force of the first torsion spring, the first insert 7 is inserted into the corresponding first slot to form a locking mechanism, thus completing the raising of the fixed plate 9.

[0036] It should be noted that when the lever 5 is moved, the lever 5 drives the first rotating shaft 4 to twist the first torsion spring to a non-twistable state. At this time, the first insert rod 7 is not completely disengaged from the non-twist end of the telescopic rod 2.

[0037] To reset the fixing plate 9, simply move the lever 5 again to disengage the first insert 7 from the corresponding first slot and lower the fixing plate 9. When the fixing plate 9 stops falling, release the lever 5 to allow the first insert 7 to insert into the corresponding first slot.

[0038] When the two extension plates 10 are pulled out, the knob is turned, causing the second rotating shaft 12 to rotate. The second rotating shaft 12 causes the push rod 13 to rotate and twist the second torsion spring. The push rod 13 pulls the two second insert rods 14 through the two hinge rods 15 to slide closer to and away from the corresponding second slots. Then, the knob is pulled away from the fixed plate 9, causing the knob to drive the second rotating shaft 12, which in turn causes the extension plates 10 to slide out of their respective mounting slots.

[0039] After the extension plate 10 slides a certain distance from its mounting slot, the knob is released. Under the elastic force of the second torsion spring, the second rotating shaft 12 reverses and drives the push rod 13 to reverse. The push rod 13 pushes the two second insert rods 14 to slide away through the hinge rod 15 and finally abut against the inner wall of the mounting slot.

[0040] Next, continue pulling the knob away from the fixing plate 9. When the two second inserts 14 correspond to the corresponding second slots, under the action of the second torsion spring, the two second inserts 14 are inserted into the corresponding second slots. At this time, the display screen 11 slides completely out of the mounting slot, and the extension plate 10 is pulled out.

[0041] It should be noted that when the knob is turned, the knob drives the second shaft 12 to twist the second torsion spring to a non-twistable state. At this time, the second insert 14 is not completely detached from the extension plate 10.

[0042] To reset the extension plate 10, simply turn the knob again. After the second insert 14 disengages from the second slot, push the knob toward the fixing plate 9. The knob drives the second rotating shaft 12, which in turn drives the extension plate 10 back into the mounting slot.

[0043] After the extension plate 10 slides back into the mounting slot a certain distance, the knob is released. Under the elastic force of the second torsion spring, the second rotating shaft 12 reverses and drives the push rod 13 to reverse. The push rod 13 pushes the two second insert rods 14 to slide away through the hinge rod 15 and finally abut against the inner wall of the mounting slot.

[0044] Next, continue pushing the knob closer to the fixed plate 9 until the two second inserts 14 are inserted into the corresponding second slots. At this point, the extension plate 10 has completed its reset.

[0045] The warning lights and the content displayed on the display screen 11 are all controlled by a microcomputer system, which is existing technology and will not be described in detail here.

[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
