As shown in fig. 1 to 13, the present invention provides a temporary protection fixed barricade for efficient interception, comprising: a plurality of car blocking units 100.

The car stop unit 100 includes two first connecting rods 110, two second connecting rods 120, a car stop rod 130, a first locking mechanism 140, two bottom plates 150, two top plates 160, two second locking mechanisms 170, two reset mechanisms 180, two side plates 190, and a housing 200.

The two first connecting rods 110 are oppositely distributed. Specifically, the two first connecting rods 110 are arranged parallel and laterally to each other.

The two second connecting rods 120 are installed in the middle of the first connecting rods 110, and both ends of the two second connecting rods are connected to the two first connecting rods 110, respectively. Specifically, two second connecting rods 120 are arranged in parallel between the two first connecting rods 110, and both ends thereof are connected to the two first connecting rods 110, respectively, and are located at the middle of the first connecting rods 110.

The barrier bar 130 is installed between the two second connecting bars 120, has one end hinged to the two second connecting bars 120, and has the other end freely extended, for intercepting and warning a vehicle. Specifically, the car blocking bar 130 is parallel to the second connecting bars 120 and is located between the two second connecting bars 120, one end of the car blocking bar 130 is hinged to the two second connecting bars 120, and the other end of the car blocking bar 130 freely extends, but the length of the car blocking bar 130 is smaller than that of the second connecting bars 120, that is, the other end of the car blocking bar 130 can rotate around the hinge center line thereof and can be hidden between the two second connecting bars 120.

The first locking mechanism 140 is used to lock the position of the stopper rod 130. Specifically, when the car stopping rod 130 rotates around its hinge center line to a position above the ground to stop the car, the first locking mechanism 140 locks the position of the car stopping rod 130 so that the car stopping rod cannot stand above the ground and cannot perform the functions of car stopping and warning.

The two bottom plates 150 are respectively installed at both sides of the car stopping rod 130, both ends of the two bottom plates are respectively fixedly connected with the two first connecting rods 110, and a plurality of car stopping nails 151 are uniformly arranged at the tops of the two bottom plates 150. Specifically, the two bottom plates 150 are respectively installed at the sides of the two second connecting rods 120 facing away from each other, the two ends of each bottom plate are respectively fixedly connected with the bottoms of the two first connecting rods 110, and the tops of the two bottom plates are fixedly installed with a plurality of vehicle stopping nails 151 for puncturing tires.

The two top plates 160 are used to hide the vehicle stopping nails 151 and provide a bearing surface for a vehicle to pass through if necessary without being pierced by the vehicle stopping nails 151. Which are respectively installed above the two bottom plates 150, both ends of which are respectively connected with the two first connecting rods 110 in a sliding manner, and the two top plates 160 are respectively provided with a clearance hole 161 corresponding to the vehicle stopping nail 151 arranged on the bottom plate 150. Specifically, the two top plates 160 are respectively installed right above the two bottom plates 150, and two ends of each top plate are respectively slidably connected to the two first connecting rods 110, that is, the bottom plates 150 can slide up and down along the first connecting rods 110. The top plate 160 is provided with a avoiding hole 161 for avoiding, and the avoiding hole 161 corresponds to the vehicle-blocking nail 151 one by one, so that the vehicle-blocking nail 151 can pass through the avoiding hole 161 to be exposed, and then puncture the tire.

Two second locking mechanisms 170 are used to lock the positions of the two top plates 160, respectively. Specifically, when the vehicle needs to pass, the vehicle stopping rod 130 is lowered, and the second locking mechanism 170 functions to lock the position of the top plate 160 so that the top plate 160 slides down when the vehicle passes, and the tire is not punctured by the vehicle stopping nails 151.

The two restoring mechanisms 180 are used to restore the positions of the two top plates 160, respectively. Specifically, in the process of stopping the vehicle, when the vehicle presses the roof panel 160, the roof panel 160 slides downwards under the action of the vehicle, the vehicle tire is punctured by the vehicle stopping nails 151 exposed out of the roof panel 160 for stopping, and after the vehicle is removed, the roof panel 160 is restored to the original position under the action of the resetting mechanism 180, so that the vehicle stopping nails 151 are hidden below the roof panel.

The two side plates 190 are respectively installed at the sides of the two first connecting rods 110, which face away from each other, in an inclined manner, and are detachably connected to the first connecting rods 110. Specifically, one side of each of the two first connecting rods 110 departing from each other is provided with a hook 111, one side of each of the two side plates 190 facing the first connecting rod 110 is provided with a support plate 191, the support plate 191 is provided with a bayonet 192 matched with the hook 111, and the side plates 190 are detachably connected with the first connecting rods 110 through the bayonet 192 and the hook 111, so that the connecting manner is quick and effective.

The housing 200 serves to hide the traffic blocking bar 130 and has an effect of improving warning and intercepting strength. Which is located on top of the two second connecting rods 120 and detachably connected to the two first connecting rods 110, wherein the detachable connection may be a screw connection or simply a placement of the housing 200 on the second connecting rods 120. The housing 200 defines an open cavity into which the bar 130 can rotate about its hinge axis. That is, in use, the housing 200 is fitted over the car stopping rod 130 to cover the car stopping rod 130. Thus, under the dual actions of the shell 200 and the car stopping rod 130, better warning and intercepting effects can be achieved.

The plurality of car stopping units 100 are sequentially distributed at intervals, and any two adjacent car stopping units 100 are detachably connected with each other. Specifically, the rear third insertion holes 112 are formed at both ends of the first connecting rod 110, both ends of the third connecting rod 210 are respectively inserted into the third insertion holes 112 of the first connecting rods 110 of two adjacent car stopping units 100, and then the third connecting rod 210 and the first connecting rod 110 are fixed by bolts (not shown in the drawings).

In practice, of course, the two car stopping units 100 located at the front and the rear are detachably connected to the two sides of the road respectively through connecting devices (not shown in the drawings), so that the car stopping units 100 can be connected with the road.

In one embodiment, the first locking mechanism 140 includes two support bars 141, a latch 142, and a first receptacle 143 disposed on the bar 130.

The two support rods 141 are respectively located at two sides of the car stopping rod 130 and between the two second connecting rods 120, and the two support rods 141 are selected here because the lateral movement of the car stopping rod 130 can be better limited, and the car stopping rod 130 can be ensured to be located in the middle between the two second connecting rods 120, so that the car stopping unit 100 looks symmetrical and beautiful, and meanwhile, the two support rods 141 can also provide better support effect. One end of each of the two support rods 141 is hinged to the two second connecting rods 120, and the other end thereof is provided with a second insertion hole 144.

The plug 142 is inserted into the first and second insertion holes 143 and 144.

In use, the stopper rod 130 is rotated, the support rod 141 is rotated, and the plug 142 is inserted into the first insertion hole 143 and the second insertion hole 144. Specifically, the plug 142 is inserted into the second insertion hole 144 of one of the two support rods 141, passes through the first insertion hole 143, and then passes through the second insertion hole 144 of the other support rod 141.

The first locking mechanism 140 of this structure has a simple structure, and if a plurality of first insertion holes 143 are formed in the car blocking lever 130 along the length direction thereof, the car blocking lever 130 can be locked at multiple angles.

In one embodiment, the second locking mechanism 170 includes a slider 171, a first guide rod 172, and a first return spring 173.

The slider 171 includes a first connecting portion 1711, two first sliding portions 1712 and a second sliding portion 1713, the two first sliding portions 1712 are respectively located at two ends of one side of the first connecting portion 1711, which is far away from the second connecting rod 120, and are fixedly connected to the connecting portion, and the second sliding portion 1713 is located at one side of the connecting portion, which faces the second connecting rod 120, and is fixedly connected to the first connecting portion 1711. Preferably, the sliding block 171 further includes a second connecting portion 1714, the second connecting portion 1714 is located at one end of the two first sliding portions 1712 far away from the car blocking rod 130, and two ends of the second connecting portion 1714 are fixedly connected to the two first sliding portions 1712 respectively. This can increase the strength of the slider 171.

The spout 113 has all been seted up to two relative one sides of head rod 110, and two first sliding portion 1712 are slidable mounting respectively in two spouts 113, and the equal interval in top of two first sliding portion 1712 is provided with a plurality of supporting parts 1715, and a plurality of supporting parts 1715 set up along the length direction of first sliding portion 1712 interval in proper order, and supporting part 1715 and roof 160 butt. Specifically, when the vehicle needs to pass through, the support portion 1715 interferes with the roof panel 160 to support the roof panel 160, i.e., lock the roof panel 160 from moving downward under the pressure of the vehicle, so that the vehicle can pass through without being punctured by the vehicle blocking nail 151.

The second connecting rod 120 is provided with a sliding hole 121, and the second sliding portion 1713 is slidably connected with the second connecting rod 120 through the sliding hole 121. Preferably, the top of the second connecting portion 1714 facing the end of the car stopping rod 130 is provided with a slope 1716, so that when the car stopping rod 130 is oriented, the sliders 171 on both sides of the car stopping rod 130 are moved away from each other by the slope 1716 under the action of the slope 1716. Causing the support 1715 to abut the top plate 160 to support the top plate 160.

The first guide rod 172 is installed in the slide hole 121, and one end thereof is fixedly connected to the second link 120 and the other end thereof is slidably connected to the second sliding portion 1713.

The first return spring 173 is sleeved on the first guide rod 172, and both ends thereof are respectively abutted against the second connecting rod 120 and the second sliding portion 1713. Naturally, the first return is under pressure to provide a stress urging the slide 171 towards the stopper rod 130.

Two sides of the top plate 160 are respectively provided with a clearance groove 162 matched with the supporting portion 1715. In this way, when the vehicle is not allowed to pass through, the avoiding groove 162 corresponds to the supporting portion 1715, and the locking of the top plate 160 by the second locking mechanism 170 can be released, so that the top plate 160 can slide downward under the action of pressure, and the vehicle stopping nail 151 can puncture the tire to perform interception.

In use, when it is desired to stop a vehicle, the vehicle stopping rod 130 is rotated, then locked by the first locking mechanism 140, and the vehicle stopping rod 130 is covered by the housing 200. At this time, the slider 171 slides in a direction approaching the stopper rod 130 by the first return spring 173, and slides to a position where the clearance groove 162 corresponds to the support portion 1715, and at this time, if the vehicle hits the stopper rod 130 and presses the top plate 160, the top plate 160 slides downward due to the loss of the support of the slider 171, so that the stopper pin 151 can pierce the tire to further intercept the vehicle.

When the vehicle is required to pass through, the housing 200 is taken away, and the car stopping rod 130 is put down, under the action of the inclined surface 1716, the sliding blocks 171 on both sides of the car stopping rod 130 are separated from each other, and the supporting portion 1715 is abutted against the roof 160 to support the roof 160, so that the vehicle can pass through the roof 160.

The second locking mechanism 170 of this structure can achieve the dual functions of locking and unlocking. When the vehicle is allowed to pass, it functions to lock the roof panel 160 so as not to puncture the tire by the vehicle stopping nails 151. When the vehicle is intercepted, it does not function, that is, the locking function of the roof panel 160 is lost, so that the roof panel 160 can slide downward, and the tire of the vehicle pressing the roof panel 160 can be punctured by the vehicle stopping nails 151.

In one embodiment, the return mechanism 180 includes a second guide rod 181 and a second return spring 182.

The second guide rod 181 is installed in the sliding groove 113 and slidably connected to the slider 171 and the top plate 160, and both ends of the second guide rod 181 are fixedly connected to the bottom and the top of the sliding groove 113, respectively. Specifically, a through hole 1717 is formed in the other first sliding portion 1712 of the slider 171, and the through hole 1717 is used for avoiding the slider 171 from the second guide bar 181, so that the second guide bar 181 does not affect the sliding of the slider 171. And the top plate 160 may also slide up and down along the second guide bar 181.

The second return spring 182 is sleeved on the second guide rod 181, and both ends thereof respectively abut against the bottom of the sliding groove 113 and the top plate 160.

Preferably, the number of the second guide rods 181 is plural, and the second guide rods 181 are sequentially arranged at intervals along the length direction of the first sliding portion, and the number of the second return springs 182 is equal to and corresponds to the number of the second guide rods 181, so that a better return effect can be achieved.

In use, when the vehicle is intercepted, the second locking mechanism 170 loses its locking effect on the top plate 160, the top plate 160 slides downwards under the pressure of the vehicle, and when the vehicle is removed, the top plate 160 is restored to the original position under the action of the second return spring 182. The reset mechanism 180 with the structure has simple structure.

The invention also provides an intercepting method of the temporary defense-deploying fixed roadblock for efficient intercepting, which comprises the following steps:

s1, the stopper lever 130 is rotated and locked by the first locking mechanism 140, and the second locking mechanism 170 unlocks the top plate 160; specifically, the car stopping rod 130 is rotated to be in an operating state at an angle with respect to the ground, and is locked by the first locking mechanism 140. At this time, the slider 171 slides in a direction approaching the stopper bar 130 by the first return spring 173, and slides to a position where the clearance groove 162 and the support portion 1715 correspond to each other, and at this time, the second lock mechanism 170 loses the lock function on the position of the top plate 160, that is, the top plate 160 can slide downward.

S2, covering the car stopping rod 130 with the shell 200;

s3, when the vehicle presses the roof panel 160 upwards, the roof panel 160 slides downwards, and the vehicle stopping nail 151 can puncture the tire.

The working principle of the invention is as follows:

in use, when a vehicle needs to be intercepted, the vehicle blocking rod 130 is rotated, is locked by the supporting rod 141 and the bolt 142 after being wound, and is covered by the shell 200, so that the intercepting strength and the warning effect are improved. At this time, the slider 171 slides in a direction approaching the stopper rod 130 by the first return spring 173, and slides to a position where the clearance groove 162 and the support portion 1715 correspond to each other. At this time, the vehicle hits the housing 200 to perform a first interception by the stopper bar 130. The vehicle which is not intercepted presses the top plate 160, at the moment, the top plate 160 loses the supporting function of the supporting part 1715, and slides downwards, so that the vehicle stopping nails 151 hidden below the top plate are exposed to puncture the tire, and secondary interception is performed, so that the intercepting effect is improved.

When the vehicle is required to pass through, the housing 200 is removed, the vehicle blocking lever 130 is rotated, and is lost to be hidden between the two second connecting rods 120, and at this time, the sliders 171 located at both sides of the vehicle blocking lever 130 are moved away from each other by the inclined surface 1716 provided at the second sliding portion 1713 to a position where the supporting portion 1715 and the roof panel 160 abut against each other. At this time, when the vehicle passes, since the roof panel 160 is supported by the support portion 1715 so as not to slide downward, the tire is not punctured by the stopper 151, and the vehicle can pass safely.
