AI Technical Summary
When the existing height limit poles are similar to the vehicle, it is difficult for drivers to find that the height limit poles will be damaged.
A municipal height limiting rod is designed. By setting up a slider, a synchronous rod, a long plate, a short tooth plate and a reflector, when the height limiting rod is impacted, the slider is driven to slide, the synchronous rod drives the movable block to move backwards, the long plate drives the short tooth plate to mesh with the gear, and the gear drives the reflector to swing, increasing the possibility of the driver discovering collision.
It effectively solves the problem that drivers are not prone to detect damage to the height limit bar. Through the reciprocating swing of the reflector, the possibility of drivers discovering that the height limit bar is affected by collision is reduced, and the risk of damage to the height limit bar is reduced.

[0003] Height limit bars are mainly used for gate-type frames at the entrances of bridges, culverts and tunnels. They are generally made of welded steel structures and serve to protect bridges, culverts and tunnels. Since the height limit pole is located above, the driver can notice the height limit pole when the vehicle is obviously higher than the height limit pole. However, when the vehicle is not much different from the height limit pole, the vehicle may sometimes accidentally hit the height limit pole. However, the height limit pole is located above the vehicle, and it is not easy for the driver to find it, which may cause damage to the height limit pole. Utility Model Content

Implementation
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] The utility model provides a municipal height limit pole, such as Figure 1-4As shown, it includes a side frame 1 and a height limiting bar 2. There are two side frames 1. The height limiting bar 2 is located between the two side frames 1. The left and right ends of the height limiting bar 2 are fixedly connected with sliders 4. The outer surfaces of the two sliders 4 are slidably sleeved with inner cavity frames 3. Two parallel frames 7 are arranged in parallel with the two inner cavity frames 3. The backs of the two sliders 4 are fixedly connected with pushing telescopic rods 15. The rear ends of the two pushing telescopic rods 15 are respectively fixedly connected to the rear inner walls of the two inner cavity frames 3. The pushing telescopic rod 15 has a tendency to push the slider 4 to contact the front inner wall of the inner cavity frame 3. When the slider 4 is subjected to thrust, the telescopic rod 15 is pushed to be compressed. When the slider 4 is not subjected to force, the pushing telescopic rod 15 is pushed to be compressed. The rod 15 pushes the slider 4 to reset, and the front ends of the two inner cavity frames 3 are fixedly connected to the sides away from each other with the sleeve frames 5, and the two sleeve frames 5 are respectively slidably sleeved on the outer surfaces of the two side frames 1, and the sides of the two sleeve frames 5 away from each other are threaded with tightening rods 6, and the two side frames 1 are both vertically arranged, and the sides of the two side frames 1 away from each other are provided with two anti-skid grooves 14, and the anti-skid grooves 14 increase the friction between the tightening rods 6 and the side frames 1 when tightening, thereby improving the stability of the sleeve frames 5, and parallel frames 7 are arranged below the two inner cavity frames 3, and the front ends of the two parallel frames 7 are respectively fixedly connected to the sides of the two side frames 1 close to each other, and the interiors of the two parallel frames 7 are slidably inserted A movable block 8 is connected, and a synchronization rod 9 is fixedly inserted on the upper surface of one end of the two movable blocks 8 that are close to each other. The two synchronization rods 9 are located between the two parallel frames 7. The height limit bar 2 is slidably sleeved on the outer surface of the two synchronization rods 9. The backs of the two movable blocks 8 are fixedly connected with long boards 10. The two parallel frames 7 are respectively slidably sleeved on the outer surfaces of the two long boards 10. The rear end of each parallel frame 7 is elastically hinged with a gear 11. The two long boards 10 are located between the four gears 11. The two synchronization rods 9 are arranged in parallel, and the two synchronization rods 9 are arranged vertically with the height limit bar 2. The two synchronization rods 9 are arranged in parallel with the two side frames 1. The upper and lower surfaces of each long board 10 are fixedly connected. It is connected to a plurality of short tooth plates 12, which are equidistantly distributed on the outer surface of the long plate 10. The shape of the slider 4 is a cross-shaped structure. When the long plate 10 moves, it pushes the plurality of short tooth plates 12 to intermittently engage with the gear 11, so that the gear 11 reciprocates under the action of the elastic hinge and the short tooth plates 12. A reflective rod 13 is fixedly connected to one end of each gear 11 close to the axis of the height limit bar 2. The four reflective rods 13 are located between the two parallel frames 7. The four reflective rods 13 are perpendicular to the height limit bar 2. The four gears 11 are parallel to the height limit bar 2. The surface of the reflective rod 13 is painted with reflective stripes, which is convenient for the driver to observe when illuminated by light at night.
[0023] The working principle is to control the degree of compression of the side frame 1 by rotating the tightening rod 6. When the tightening rod 6 is loosened, the height of the sleeve frame 5 can be changed, thereby changing the height of the height limit bar 2. When the height limit bar 2 is collided, the height limit bar 2 drives the slider 4 to slide in the inner cavity frame 3, so that the telescopic rod 15 is compressed, and the movable block 8 is driven to move backward through the synchronization rod 9. The long plate 10 drives the short tooth plate 12 to move backward and continuously mesh with the gear 11. The gear 11 drives the reflective rod 13 to swing. When the gear 11 is disengaged from the short tooth plate 12, it is reset under the action of the elastic hinge, so that the reflective rod 13 swings back and forth, so that the driver can easily find that the upper height limit bar 2 is collided.
