Description

Road security device

The application is a divisional application of an invention patent application with the application number of 2014105266478, the application date of 2014-10-06 and the name of 'a road security device acting on a vehicle'.

Technical Field

The invention belongs to the fields of vehicle safety, traffic safety and security, in particular to the fields of measuring and displaying vehicle speed, preventing automobile overspeed and limiting automobile speed to ensure safety. Technical Field

The existing automobile speed measurement needs electricity, and once the electricity is interrupted, the speed cannot be measured. The existing device for preventing the automobile from overspeed is a bump laid above the road surface, also called a deceleration strip. In fact, many vehicles can simply pass through the speed bump at high speed, if comfort is not a concern. There are also military units where the doorway has powered, underground raisable, tire puncturing devices that require manual operation to be effective and which may have passed over a security device once a terrorist driving the vehicle is detected by a guard or sentinel.

In some areas, where vehicle speeding is considered an offender, such as military exclusion zones, where traffic control is used to prevent terrorist incidents, where vehicle speed is severely limited, and where an abnormal vehicle passing at high speed is considered an offender, security personnel should take action (including in extreme cases killing the vehicle occupants to resolve the problem). However, criminals hit at high speed and leave the security personnel with little time to react.

The specific implementation mode is as follows:

the first embodiment is as follows: referring to fig. 1, the structure of the present invention is schematically shown.

A induction system for vehicle speed measurement, including pressure board 1, characterized by:

the pressing plate rotating shaft 11 is arranged below the road surface 3, the pressing plate 1 can rotate around the pressing plate rotating shaft 11, the pressing plate 1 extends upwards, the upper end of the pressing plate 1 extends out of the road surface 3,

the lower end of the pressure plate 1 is fixedly connected with a pressure gear 12, the circle center of the pressure gear 12 is superposed with the circle center of the pressure plate rotating shaft 11,

the pressing plate 1 is also provided with a first pull-back device 13 for leading the pressing plate 1 to return, one end of the first pull-back device 13 is arranged on the pressing plate 1, the other end is arranged on an underground fixture,

a first ratchet 2 driven by a pressure gear 12 is also provided.

The first pullback means 13 is a rubber rope or a spring.

One skilled in the relevant art will recognize that: the pressure plate pivot axis 11 is parallel to the road surface, or substantially parallel to the road surface, and because the road surface is often not exactly a plane, the term "substantially" is a technical requirement known to those skilled in the relevant art.

It is obvious that: one skilled in the relevant art will also recognize that: the road surface is provided with an opening for the pressing plate to rotate.

Defining: first ratchet 2: the first ratchet 2 is a ratchet like a common bicycle rear wheel gear: when the bicycle is pedaled and moved forward, the ratchet wheel of the rear wheel of the bicycle drives the wheel to drive the bicycle to move; if the pedal of the bicycle is rotated in the opposite direction, the bicycle chain drives the gear ring on the surface of the ratchet wheel of the rear wheel to rotate, and the rear wheel of the bicycle does not obtain power. The first ratchet 2 is prior art, therefore, the present invention does not describe the detailed structure of the first ratchet 2. By way of further example: when the first ratchet wheel 2 rotates anticlockwise, the whole ratchet wheel rotates, namely the ratchet wheel can output power; when the first ratchet wheel 2 rotates clockwise, only the gear ring on the surface of the ratchet wheel rotates, and the ratchet wheel does not output power under the state.

The working principle of the first embodiment is as follows: the wheel rolls and presses the pressing plate 1, the pressing plate 1 rotates around the pressing plate rotating shaft 11, so that the pressing gear 12 also rotates, and the rotation of the pressing gear 12 drives the first ratchet wheel 2 to rotate. Because of the different vehicle speeds, the angular speeds at which the pressure plate 1 rotates differ, i.e. the wheels of different speeds are pressed over, resulting in different rotational speeds of the first ratchet 2. In order to return the pressing plate 1 after the pressing, the first retracting device 13 is needed to wait for the next pressing, and a rubber rope, a rubber rope and a spring can be used. The first retracting device 13 is such that the first ratchet 2 does not output power during the process of retracting the pressing plate 1 to the home position, as compared to the state in which the bicycle chain is reversed.

After reading this description, the person skilled in the relevant art will know the appropriate location for the first pullback means 13 to be mounted.

One skilled in the relevant art, having reviewed this disclosure, should understand that: the axis of the pressure plate rotating shaft 11 should be below the road surface and in the horizontal direction. The width of the pressure plate 1 can be changed according to actual requirements such as road surface width.

Example two: referring to fig. 2, the structure of the present invention is schematically shown.

In order to further optimize the first embodiment, the adopted technical scheme may be as follows: the pressure plate 1 is curved in the direction of the advancing wheel at the portion extending beyond the road surface 3, and the road surface 3 is provided with a recessed area for the rotation of the pressure plate 1.

Compared with the first embodiment, the technical scheme can prolong the service life of the pressing plate 1, because the straight pressing plate 1 is easy to crush.

The road surface 3 is provided with a recessed area for the rotation of the pressure plate 1, meaning: the rotation of the pressing plate needs space, and is not suitable for being blocked by obstacles, and the depressed area is a space for the rotation of the pressing plate on the road surface.

Example three: referring to fig. 3, the structure of the present invention is schematically shown. For a clearer illustration of the partial structure, reference is made to fig. 4, which fig. 4 is intended to show the manner of connection of the turn disc 43 and the turn lever 42. Fig. 4 is a plan view.

A display device for automobile speed measurement, including second ratchet 41, characterized by:

the second ratchet wheel 41 is fixedly connected with one end of the rotating rod 42, and the rotating shaft of the rotating rod 42 is overlapped with the rotating shaft of the second ratchet wheel 41,

the other end of the rotating rod 42 is fixedly connected with a rotating disk 43, the plane of the rotating disk 43 is perpendicular to the rotating shaft of the rotating rod 42, the rotating disk 43 is connected with at least two swinging rods 44 in a hinged connection mode, the hinged rotating shaft is perpendicular to the rotating shaft of the rotating rod, the hinged rotating shaft is perpendicular to the normal line of the rotating disk 43,

one end of the swinging rod 44 is connected with the rotating disc 43, the other end is connected with the heavy object 45,

a sleeve 47 is sleeved on the rotating rod 42 at a position between the rotating disk 43 and the second ratchet wheel 41, one end of the second pull-back device 46 is fixedly connected with the rotating rod 44, the other end is fixedly connected with the sleeve 47, the sleeve 47 is also fixedly connected with a rotating cylinder 48, the rotating axis of the rotating cylinder 48 is coincided with the rotating axis of the rotating rod 42,

a speed scale 51 marked with scales 52 for determining the speed is arranged above the road surface 3.

The second pullback means 46 is a rubber rope or a spring.

One skilled in the relevant art will recognize that: the rotation axis of the rotating rod 42 is vertical, or: the axis of the rotating rod is vertical. The second ratchet wheel 41 is fixedly connected with one end of the rotating rod 42, and the term means: when the second ratchet wheel 41 drives the rotating rod 42 to rotate, the second ratchet wheel 41 and the rotating rod 42 do not slip, that is, rotate at the same angular speed.

Defining: normal line of the rotating disk 43: a line coplanar with the surface of the rotary disk 43 and passing through the center of the rotary disk is a normal line of the rotary disk 43.

Defining: second ratchet 41: the second ratchet 41 and the first ratchet 2 are both: when the power-driven bicycle rotates in a certain direction, power can be output, and when the power-driven bicycle rotates in the opposite direction, power is not output.

The working principle of the third embodiment is as follows: the second ratchet wheel 41 is driven by the outside to rotate, and drives the rotating rod 42, the rotating disk 43, the swinging rod 44 and the weight 45 to rotate together, and the larger the rotating speed is, the higher the weight 45 and the swinging rod 44 are lifted up. The lifting of the weight 45 drives the sleeve 47 to lift through the second pulling device 46, and the sleeve 47 drives the rotary cylinder 48 to lift. The rising height of the rotary cylinder 48 reflects the rotational speed of the second ratchet 41.

The shape of the rotating disc 43 is preferably circular. One skilled in the relevant art will recognize that: the swinging rod 44 and the weight 45 connected with the swinging rod 44 have the mass center located on the axis of the rotating rod 42, and the arrangement can ensure that the vibration is reduced when the rotating rod rotates.

The sleeve 47 can move up and down along the rotating rod 42. Alternatively, the rotating rod 42 restricts the movement path of the sleeve 47 so that the sleeve 47 can move only up and down. The sleeve 47 is preferably cylindrical in shape.

After reviewing this application, one skilled in the relevant art should understand that: the sleeve 47 is fixedly connected with a rotating cylinder 48, and the preferable mode is as follows: the lower part of the rotating cylinder 48 is fixedly connected with the lower part of the sleeve 47. So coupled, the movement of the trip rod 44 is not affected. It can also be said that the preferred mode is: the swing lever 44 and the rotating disk 43 are provided inside the rotating cylinder 48. To avoid strong vibrations, the rotary cylinder 48 is preferably circular in cross-section.

After reviewing this application, one skilled in the relevant art should understand that: the rotary cylinder moves up and down, including a movement that protrudes out of the road surface, so the road surface should be provided with a corresponding opening so that the rotary cylinder can be raised above the road surface.

Example four: see fig. 1 and 3, or fig. 2 and 3.

A device for vehicle speed measurement, including induction system and the display device who tests the speed, characterized by:

the induction device is such that:

a first ratchet wheel 2 driven by a pressure gear 12 is also provided,

the display device is such that:

above the road surface 3 a speed ruler 51 marked with scales 52 for determining the speed is arranged,

the first ratchet 2 and the second ratchet 41 are driven by a linkage.

The first pullback means 13 is a rubber rope or a spring. The second pullback means 46 is a bungee cord or spring.

The pressure plate 1 is bent in the direction of the forward direction of the wheel at a portion protruding from the road surface 3.

The linkage is a chain.

The linkage is a gear set or gearbox.

Based on the first, second and third embodiments, the working principle of the fourth embodiment can be simply introduced: the wheel presses against the pressure plate 1, causing: the first ratchet 2 rotates, and the first ratchet 2 rotates the second ratchet 41 through the linkage, thereby raising the rotary cylinder 48. The wheel speed is the only factor that affects the elevation of the rotary drum 48, so vehicles of different speeds pass through the drum 48 at different elevations. When the wheel is driven, the rotary cylinder 48 is lowered, and the second ratchet 41 does not drive the linkage, as described in the third embodiment. One ratchet wheel rotates and the other ratchet wheel also rotates, i.e. is linked, through a linkage, which belongs to the prior art.

Is the vehicle weight affect the elevation of the rotary drum 48? The answer is: without affecting, because the weight of the vehicle is sufficiently heavy compared to the mechanical friction of the various components of the invention. When a vehicle weighing 1 ton and a vehicle weighing 50 ton press the pressing plate 1 at the same speed, the rotation speed of the pressing plate 1 is not different due to the difference in vehicle weight.

Is the front wheel pressed and the rear wheel pressed, affecting the height of the rise? The answer is: has no influence. Since the rise height is determined by the rotational speed of the rotary disk 43. One skilled in the relevant art will recognize that the measurement is allowed to have errors.

How is the scale 52 identified by the speed scale 51 available? The answer is: the best way is to know the speed of the vehicle by other devices or methods, then let the vehicle with the known speed pass through the pressure plate 1, and then mark the scale 52 on the speed ruler 51. The person skilled in the relevant art can also calculate the ratio of the rotational speeds, the ratio of the transmission speeds and the knowledge of the dynamics-this method is more troublesome than the method of experimental determination and takes many factors into account, so it is also recommended to use the experimental method to obtain the result.

The fifth embodiment, referring to fig. 5, is a schematic structural diagram of the fifth embodiment.

The display device may also be such that:

the vehicle speed display device comprises a rotary drum 48 and is characterized in that:

an upward pushing cylinder 61 is supported above the rotary cylinder 48,

further comprising: a third ratchet wheel 62 driven by the push-up cylinder 61 and allowing the push-up cylinder 61 to move only upward, and a speed scale 51 marked with a scale 52 for determining speed is provided above the road surface 3.

The method can also comprise the following steps: the side surface of the push-up cylinder 61 is provided with a friction layer 64 for increasing the friction force applied to the driving third ratchet wheel 62.

This may also be the case: the side surface of the upper pushing cylinder 61 is provided with an anti-rotation piece 611, the anti-rotation piece 611 is fixedly connected with the upper pushing cylinder 61, and the anti-rotation piece 611 is embedded in and fixed with the fixed non-movable positioning block 612.

Defining: third ratchet 62: the third ratchet 62 can only rotate in one direction, and if the third ratchet needs to rotate in the opposite direction, the locking mechanism needs to be released, and the ratchet belongs to the prior art, such as a lifting device commonly used in engineering: the inside of the hoist is provided with a ratchet wheel which rotates in one direction, and if the hoist needs to rotate in the opposite direction, the locking mechanism needs to be manually released.

This technical scheme can solve the following technical problems: the device can be used with the intention of knowing the highest vehicle speed over a certain period of time. Because the third ratchet 62 can only raise the push-up barrel 61 without lowering it without releasing the locking mechanism of the third ratchet 62.

It should also be noted that: the push-up cylinder 61 is supported above the rotary cylinder 48. Here, a support, rather than a fixed connection. If the vehicle speed is higher than the maximum vehicle speed, the push-up cylinder 61 continues to be raised, and if the vehicle speed is not the maximum vehicle speed, although the rotary cylinder 48 is raised, the rotary cylinder 48 cannot touch the push-up cylinder 61 staying above it.

Referring to fig. 6, fig. 6 is a plan view emphasizing that the push-up cylinder 61 is constrained. The side surface of the upper pushing cylinder 61 is provided with an anti-rotation piece 611, the anti-rotation piece 611 is fixedly connected with the upper pushing cylinder 61, and the anti-rotation piece 611 is embedded in and fixed with the fixed non-movable positioning block 612. This statement is to be interpreted as follows: the rotating cylinder 48 rotates in the ascending process, the rotating cylinder 48 causes the push-up cylinder 61 to rotate, and the rotation of the push-up cylinder 61 causes the push-up cylinder 61 and the third ratchet 62 to be not well matched, so the rotation prevention piece 611 and the positioning block 612 are used for restricting the movement of the push-up cylinder 61, and the push-up cylinder 61 can only move up and down but cannot rotate. In view of the present disclosure, it should be appreciated that the positioning block 612 can be disposed on a fixed object, such as a concrete block installed under the road surface 3. It will also be appreciated by those skilled in the relevant art that the third ratchet 62 requires manual unlocking to lower the push-up cylinder 61.

In order to better match the pushing-up cylinder 61 and the third ratchet wheel 62, a friction layer 64 for increasing the friction force applied to drive the third ratchet wheel 62 can be arranged on the side surface of the pushing-up cylinder 61. The friction layer 64 may be made of felt applied to the side of the upper push cylinder 61. In FIG. 6, there is a gap between the third ratchet 62 and the friction layer 64 for the reader to distinguish the friction layer 64 from the third ratchet 62. in practice, one skilled in the relevant art will recognize that the third ratchet 62 and the friction layer 64 should be in contact and have the appropriate pressure.

When one skilled in the relevant art sees the information of the present application, it should be understood that, in order to support the push-up cylinder 61, the rotary cylinder 48 should be provided with a design for supporting the push-up cylinder 61 above, such as: the upper part of the rotary cylinder 48 is closed, and the upper push cylinder 61 is supported by the top surface of the rotary cylinder 48.

The highest speed of the passing car in the period of time can be known by the highest position of the push-up cylinder 61.

Example six:

see fig. 7.

The vehicle speed display device with friction damping comprises a rotary drum 48, and is characterized in that:

an upward pushing cylinder 61 is supported above the rotating cylinder 48, a friction damping device 91 for increasing sliding friction force to the upward pushing cylinder 61 is clamped on the side surface of the upward pushing cylinder 61,

The friction damping means 91 is felt or sponge.

The fourth example has a disadvantage that: 1, the driver can see the speed ruler 51 if he wants to know his own speed, but the rotary cylinder 48 for indicating the speed in the fourth embodiment is lowered to a height immediately after the wheel presses the pressure plate 1, so that the driver cannot easily see the problem that the rotary cylinder 48 is raised to the maximum height.

In the sixth embodiment, this deficiency can be solved: the rotary cylinder 48 is lifted to push the push-up cylinder 61 to be lifted, but the push-up cylinder 61 is slowly lowered by the resistance of the friction damping device 91 in the process of lowering, so that the driver can easily see the maximum position where the push-up cylinder 61 is lifted.

It should be noted that: 1, will the push-up cylinder 61 not rise slowly? The answer is: the speed at which the push-up cylinder 61 is raised is determined only by the speed at which the rotary cylinder 48 is raised. Since the push-up cylinder 61 receives a thrust force (applied by the rotary cylinder 48) and also receives a resistance force (applied by the friction damper device 91), and the thrust force is much larger than the resistance force, the speed at which the push-up cylinder 61 rises is determined only by the rising speed of the rotary cylinder 48. 2, it will be appreciated by those skilled in the relevant art that the speed display means should be located at a roadside position in front of the driver, so that the driver can see the speed indication and driving safety is facilitated. 3, the design has the advantages that: because of the friction damping device 91, the push-up cylinder 61 is less affected by the fact that the push-up cylinder continues to rise due to inertia during the rising process. 4, due to inertia, the push-up cylinder 61 can continue to rise a height that would cause a large error or even mistake in the display speed? The answer is: will not. Because the scale 52 of the speed ruler 51 is obtained experimentally.

Example seven:

see fig. 8. The vehicle speed display device with electromagnetic damping comprises a rotary drum 48, and is characterized in that:

a push-up cylinder 61 is supported above the rotating cylinder 48, the push-up cylinder 61 is made of a conductor, a magnet 92 is arranged on the side surface of the push-up cylinder 61, the magnet 92 is close to but not in contact with the push-up cylinder 61,

As will be appreciated by those skilled in the relevant art in view of the present disclosure, the magnet 92 dampens the movement of the push-up cylinder 61. One skilled in the relevant art will appreciate the reasons why the push-up cylinder 61 employs a conductor. The push-up cylinder 61 is preferably made of copper. The magnet 92 is made of a strong permanent magnet, of which the strong words are clear to those skilled in the relevant art.

Example eight:

see fig. 9.

The utility model provides a road security device of thorn tire, includes induction system and the puncture device that tests the speed, characterized by:

the induction device is such that:

a first ratchet wheel 2 driven by a pressure gear 12 is also provided,

the piercing means is such that:

an upper pushing cylinder 61 is supported above the rotating cylinder 48, a thorn-shaped object 63 is fixedly connected above the upper pushing cylinder 61, the road surface 3 is provided with an opening for lifting the thorn-shaped object 63,

the first ratchet wheel 2 and the second ratchet wheel 41 are driven by a linkage,

and a third ratchet 62 driven by the push-up cylinder 61 and allowing the push-up cylinder 61 to move only upward.

The method can also comprise the following steps: the side surface of the push-up cylinder 61 is also provided with a friction layer 64 for increasing the friction force applied to the driving third ratchet wheel 62.

The method can also comprise the following steps: the side surface of the upper pushing cylinder 61 is also provided with an anti-rotation piece 611, the anti-rotation piece 611 is fixedly connected with the upper pushing cylinder 61, and the anti-rotation piece 611 is embedded in and fixed with the non-movable positioning block 612.

One skilled in the relevant art will recognize that: the technical effect that relevant parameters are set according to requirements, including the position of the thorn-shaped object 63 below the road surface 3, can be achieved: when the speed of the automobile exceeds a certain value, the thorn-shaped objects 63 can extend out of the road surface 3, and the purpose of puncturing tires is achieved. Since the foregoing embodiments are explained, the present embodiment does not require detailed explanation of each component.

Example nine:

see fig. 10. Automobile driving safety device based on opto-coupler 81, including induction system and the piercing depth who tests the speed, characterized by:

the induction device is such that:

a first ratchet wheel 2 driven by a pressure gear 12 is also provided,

the piercing means is such that:

also provided with: an optical coupler 81 for judging whether the height of the rotary cylinder 48 exceeds a standard,

the controller 82 controls the position of the lifting rod 83, a puncturing part 84 for puncturing the tire is arranged at the top end of the lifting rod 83, and the controller 82 is connected with the optical coupler 81 to acquire the working state of the optical coupler 81.

The position is judged by the optical coupler 81, the prior art is adopted, and the controller 82 is used for controlling the movement of an object, and the prior art is adopted.

The eighth embodiment has disadvantages: the height at which the spikes 63 rise is related to vehicle speed. The vehicle speeds of 30 km/h and 70 km/h are different from each other in the height of the raised thorn 63, and in order to prevent the vehicle from advancing, the tire needs to be punctured, and many times, the puncture height needs to be fixed or high enough, and the eighth embodiment cannot solve the problem. Example nine there are advantages over example eight: the controller 82 can control the rising height of the rising rod 83, once the speed of the automobile exceeds a certain value, the rotary drum 48 rises and reaches a certain height, and after the optical coupler 81 recognizes, the controller 82 controls the rising rod 83 to move.

Those skilled in the relevant art will recognize that the piercing height is set as a practical matter. It is also known that: with the direction of vehicle travel as the front, the piercing device should be positioned in front of the sensing device and at a reasonable distance as needed.

Example ten:

see fig. 11. Road security device of impaling overspeed automobile tire, including induction system and the impaling device that tests the speed, characterized by:

the induction device is such that:

a first ratchet wheel 2 driven by a pressure gear 12 is also provided,

the piercing means is such that:

the V-shaped rotating rod 71 is composed of a long rod part and a short rod part, the long rod part is longer than the short rod part, obviously, the long rod part and the short rod part of the V-shaped rotating rod 71 are fixedly connected, and actually, a steel bar is usually bent to form the V-shaped rotating rod. For typing convenience, the lower case letter V and the upper case letter V are equivalent when expressing the V-shaped turn bar.

A rotating shaft 7 is arranged at the junction of the long rod part and the short rod part (also called as a joint), the V-shaped rotating rod 71 can rotate around the rotating shaft 7, the position of the rotating shaft 7 is positioned above the rotating cylinder 48 and is positioned at the outer side of the rotating cylinder 48,

one end of the long rod part of the V-shaped rotating rod 71 is connected with the short rod part, the other end is a sharp end for puncturing the tire, a center of gravity adjusting rod 721 is fixedly connected to a certain position between the sharp end and the rotating shaft 7, one end of the center of gravity adjusting rod 721 is connected to the long rod part, the other end is fixedly connected with a center of gravity adjusting counterweight 722, and a person skilled in the relevant field can determine the installation position of the center of gravity adjusting rod 721 through non-creative labor, such as calculation by adopting the existing scientific knowledge, and then, such as measurement through experiments.

And: when the sharp end of the V-shaped rotating rod 71 is located below the road surface 3, the center of gravity of the whole of the V-shaped rotating rod 71, the center of gravity adjusting rod 721 and the center of gravity adjusting weight 722 is as follows: a vertical line is made through the rotating shaft 7, and then, the rotating cylinder 48 and the center of gravity are arranged at both sides of the vertical line,

the short shaft portion of the V-shaped rotary rod 71 is restrained by the string 73, so that the sharp end of the V-shaped rotary rod 71 is normally positioned below the road surface 3,

one end of the short rod part of the V-shaped rotating rod 71 is connected with the long rod part, and the other end is positioned above the rotating cylinder 48, so that the rotating cylinder 48 can touch the short rod part when ascending.

The working principle of the embodiment is as follows: after the car is overspeed, the rotary drum 48 is lifted to a certain height, then the short rod part of the V-shaped rotary rod 71 is pushed, and then the string 73 is pulled off, and the center of gravity of the V-shaped rotary rod 71 is set, which inevitably causes the rotation of the V-shaped rotary rod 71, so that: referring to fig. 12, when the V-shaped rotating rod 71 leans against the gap of the road surface 3 and the tire of the automobile is pressed, the V-shaped rotating rod 71 can not rotate any more by selecting a proper inclination angle, so as to puncture the tire.

"the sharp end of the V-shaped rotating rod 71 is normally under the road surface 3", explaining "normal": the normal state refers to a state where the vehicle is not over-speeding, that is, the V-shaped rotary lever 71 is in a state of waiting for rotation.

The optimized technical scheme is as follows: the string 73 is such a string 73: the force required for breaking the string 73 is F1, the pulling force applied to the string 73 when the sharp end of the V-shaped rotating rod 71 is in a static state under the road surface 3 is F2, F1 is 1.2 times to 1.5 times F2, of course, F1 may also be equal to 1.3 times F2, F1 may also be equal to 1.4 times F2, F1 may also be equal to 1.35 times F2, and F1 may also be equal to 1.36 times F2.

The string 73 may not be too strong, too strong to break easily, or too weak to break spontaneously.

The optimized technical scheme is as follows: the rotating shaft 7 is a ratchet. It will be appreciated by those skilled in the relevant art that in the present embodiment, the rotating shaft 7 preferably serves two functions: 1, the V-shaped rotating rod 71 can rotate, and 2, after the long rod part of the V-shaped rotating rod 71 rises, the V-shaped rotating rod 71 can be prevented from reversely rotating. Therefore, it is preferable that the rotating shaft 7 is a ratchet. This ratchet allows the V-shaped rotary rod 71 to rotate after the string 73 is broken, and ensures that the V-shaped rotary rod 71 does not rotate back any more.

Is it not a necessary solution that the rotating shaft 7 is a ratchet? The answer is: is not a necessary solution. Because the V-shaped rotating rod 71 can be prevented from rotating any more by selecting an appropriate inclination angle, and the tire can be punctured. In this regard, one skilled in the relevant art can determine the relevant parameters through routine mechanical calculations or a limited number of experiments.

Example eleven:

see fig. 13, 14, 15.

The V-shaped turning lever 71 is composed of a plurality of long lever parts, and the long lever parts are fixedly connected to the turning lever 74, and the long lever parts are arranged in parallel on the same plane.

Still including covering in the apron 700 of road surface 3, apron 700 has seted up: a hole which is used for the long rod part to pass through when rotating and has a strip shape.

The technical scheme can ensure that the automobile cannot bypass, and can play a role in security as long as the automobile runs on the set road. The person skilled in the relevant art can set the values of the device required by the present invention according to the actual situation, for example, the rotating cylinder is light, the distance between the first ratchet wheel and the second ratchet wheel is appropriate, and the appropriate transmission device is selected according to the distance.

One skilled in the relevant art can use the above embodiments in appropriate combinations to arrive at new solutions.

The invention has simple structure, can be used for measuring the vehicle speed or limiting the vehicle speed, and plays a better role in measurement or security.
