[0004] To address the problems existing in the prior art, the present invention provides a security roadblock device, comprising a main housing and a secondary housing;

[0005] Connecting frames are arranged between the main housing and the auxiliary housing. Rollers are installed at the bottom of the main housing, the auxiliary housing, and the connecting frames.

[0006] Two grid plates are installed between the main housing, connecting frame, and auxiliary housing. The two grid plates are arranged in a V-shape. The right end of the grid plate is rotatably connected to the connecting frame or auxiliary housing. The surfaces of the main housing and connecting frame are opened with sliding grooves. The left end of the grid plate slides vertically with the sliding groove. The main housing, connecting frame, and auxiliary housing move closer or further apart, so that the right end of the grid plate slides along the sliding groove, allowing the two grid plates to unfold or move closer together.

[0007] Preferably, a locking component is provided at one end of the slide near the middle of the connecting frame. The locking component includes a torsion bar. A torsion groove is opened in the connecting frame, and the torsion groove passes through the end of the slide. The torsion bar rotates in the torsion groove by a torsion spring. A gear is fixed in the torsion groove at the right end of the grid plate. An arc-shaped rack is provided at the bottom end of the torsion bar to the left of the gear. A guide wheel is rotatably provided at the left end of the grid plate and rolls in the slide. An arc-shaped protrusion is provided at the end of the torsion bar away from the arc-shaped rack, and the arc-shaped protrusion protrudes at the end of the slide.

[0008] Preferably, when the guide wheel passes over the arc-shaped protrusion and is caught at the end of the groove by the arc-shaped protrusion, the arc-shaped rack does not contact the gear.

[0009] Preferably, the arc-shaped rack and the gear surface have aligned reverse teeth, so that when the two grid plates come together, the gear and the arc-shaped rack are locked together, and when the two grid plates are unfolded, the engagement between the gear and the arc-shaped rack is disengaged.

[0010] Preferably, a take-up roller is symmetrically and rotatably installed inside the secondary housing. A shielding cloth is wound on the surface of the take-up roller. Openings are symmetrically opened on the surface of the secondary housing. The shielding cloth is led out through the openings and connected to the main housing, so that the shielding cloth covers the connecting frame and grid plate that unfolds between the main housing and the secondary housing. A worm gear is fixed at the end of the take-up roller. The worm gear is meshed with a worm, and the worm is rotatably connected to the secondary housing.

[0011] Preferably, two guide rollers are symmetrically rotated and installed inside the opening via damping bearings, and the shielding cloth passes between the two guide rollers, with the guide rollers pressing against the shielding cloth.

[0012] Preferably, a pad is fixed to the bottom of the main housing, the pad extends into the secondary housing, and a groove is opened at the bottom of the connecting frame, so that the pad is inserted into the groove when the connecting frames are close together.

[0013] Preferably, a positioning assembly is provided on the top of the main housing and the auxiliary housing. The positioning assembly includes a cylindrical shell, which is fixed to the top of the main housing. A nail rod is fixed to the top of the auxiliary housing, and the nail rod is aligned with the cylindrical shell. The surface of the nail rod is evenly provided with countersunk grooves. A pry bar is elastically mounted on the surface of the cylindrical shell by a torsion spring. A countersunk block is fixed to the end of the pry bar.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0030] like Figure 1-5 As shown, a security roadblock device includes a main box 1 and a secondary box 2. Several connecting frames 3 are arranged between the main box 1 and the secondary box 2. The connecting frames 3 are directional frame structures. Rollers are installed at the bottom of the main box 1, the secondary box 2, and the connecting frames 3. Two grid plates 4 are arranged between the main box 1, the connecting frames 3, and the secondary box 2. The two grid plates 4 are arranged vertically in a V-shape. The right end of the grid plate 4 is rotatably connected to the connecting frame 3 or the secondary box 2. The surfaces of the main box 1 and the connecting frames 3 are provided with upper and lower sliding grooves 31. The left end of the grid plate 4 is rotatably installed with a guide wheel 41, which slides vertically with the sliding groove 31.

[0031] like Figure 6-7As shown, a locking component 7 is provided at one end of the slide 31 near the middle of the connecting frame 3. The locking component 7 includes a torsion bar 72. A torsion groove 71 is opened in the connecting frame 3. The torsion groove 71 passes through the end of the slide 31. The torsion bar 72 rotates in the torsion groove 71 by a torsion spring. The right end of the grid plate 4 rotates and passes into the torsion groove 71 and is fixed with a gear 74. An arc-shaped rack 73 is provided at the bottom end of the torsion bar 72 on the left side of the gear 74. An arc-shaped protrusion 75 is provided at the end of the torsion bar 72 away from the arc-shaped rack 73. The arc-shaped protrusion 75 protrudes at the end of the slide 31.

[0032] The rollers make the device easy to move. When setting up roadblocks, keep the main box 1 fixed and pull the auxiliary box 2 to move it, so that the connecting frame 3 unfolds. During the unfolding process, the connecting frame 3 will pull the grid plate 4, so that the two grid plates 4 gradually move closer together until the guide wheel 41 slides to the end of the slide groove 31. The grid plate 4 and the connecting frame 3 form a stable unfolded state. The unfolding width of the device can be adjusted according to the roadblock setting requirements. During the unfolding process, the connecting frame 3 is released one by one. The unfolding width can be adjusted by adjusting the number of connecting frames 3 released.

[0033] The rightmost connecting frame 3 and the sub-box 2 have unrestricted rotation of the grid plate 4. However, the gears 74 at the rotating ends of the grid plates 4 distributed to the left are engaged by the arc-shaped rack 73, preventing the grid plates 4 from rotating. This keeps the connecting frame 3 closed. Moving the sub-box 2 causes the rightmost grid plate 4 to unfold. When the two rightmost grid plates 4 approach each other, the guide wheels 41 at their ends slide to the end of the slide groove 31. The guide wheels 41 press against the arc-shaped protrusion 75, causing the torsion bar 72 to deflect against the elastic force. The arc-shaped rack 73 disengages from the gear 74, releasing the lock of the grid plate 4 at the second position on the right. This allows the connecting frame 3 at the second position on the right to move and unfold. Similarly, each approaching grid plate 4 releases the angle fixation of the next grid plate 4, thus keeping the connecting frame 3 unfolded one by one.

[0034] When the guide wheel 41 passes over the arc-shaped protrusion 75 and is locked at the end of the slide groove 31 by the arc-shaped protrusion 75, the arc-shaped rack 73 does not contact the gear 74. At this time, the next position grid plate 4 is unlocked, and the arc-shaped protrusion 75 has a locking effect on the guide wheel 41, so that the unfolded connecting frame 3 has a certain shaping strength and is not easy to retract on its own.

[0035] The surfaces of the arc-shaped rack 73 and the gear 74 have aligned reverse teeth, which cause the gear 74 and the arc-shaped rack 73 to jam when the two grid plates 4 come together, preventing the connecting frame 3 from unfolding on its own. When the two grid plates 4 unfold, the engagement between the gear 74 and the arc-shaped rack 73 will disengage, making it easy to quickly retract all unfolded connecting frames 3.

[0036] like Figure 2 , Figure 5 , Figure 8As shown, a pad 11 is fixed at the bottom of the main housing 1. The pad 11 extends into the secondary housing 2. A groove 32 is opened at the bottom of the connecting frame 3. When the connecting frame 3 is retracted, the pad 11 is inserted into the groove 32, which forms a support for all the connecting frames 3. All the connecting frames 3 are completely retracted into the main housing 1. The secondary housing 2 fits against the main housing 1 to completely house the connecting frames 3. With the support of the pad 11, it is convenient to transfer the equipment.

[0037] like Figure 1 , Figure 3 , Figure 11 As shown, a positioning component 5 is provided on the top of the main housing 1 and the auxiliary housing 2. The positioning component 5 includes a cylindrical shell 52, which is fixed to the top of the main housing 1. A nail rod 51 is fixed to the top of the auxiliary housing 2. The nail rod 51 is aligned with the cylindrical shell 52. The surface of the nail rod 51 is evenly provided with countersunk grooves 53. A pry bar 55 is elastically mounted on the surface of the cylindrical shell 52 by a torsion spring. A countersunk block 54 is fixed to the end of the pry bar 55. The countersunk block 54 is inserted into the cylindrical shell 52 and engages with the countersunk grooves 53. A top block 56 is elastically slidable inside the cylindrical shell 52 by a spring. The nail rod 51 is inserted into the cylindrical shell 52 and presses the top block 56 to move.

[0038] When storing the equipment, the processing sub-box 2 moves closer to the main box 1, and all connecting frames 3 are hidden inside the main box 1 and sub-box 2. The nail rod 51 is inserted into the cylindrical shell 52. The nail rod 51 presses against the top block 56 to overcome the elasticity and slide. Through the engagement of the reverse tooth block 54 and the reverse tooth groove 53, the nail rod 51 and the cylindrical shell 52 are kept in a fixed insertion. The main box 1 and sub-box 2 are closed and locked. When unfolding the device, press the lifting handle 55 to make the reverse tooth block 54 lift up and disengage from the engagement reverse tooth groove 53. Under the action of elasticity, the top block 56 pushes the nail rod 51 out of the cylindrical shell 52, and the sub-box 2 separates from the main box 1.

[0039] like Figure 1 , Figure 2 , Figure 9 , Figure 10 As shown, a take-up roller 61 is symmetrically and rotatably installed inside the secondary housing 2. A shielding cloth 6 is wound on the surface of the take-up roller 61. A through-hole 62 is symmetrically opened on the surface of the secondary housing 2. The shielding cloth 6 is led out through the through-hole 62 and connected to the main housing 1, so that the shielding cloth 6 covers the connecting frame 3 and grid plate 4 that unfold between the main housing 1 and the secondary housing 2. A worm gear 65 is fixed at the end of the take-up roller 61. The worm gear 65 is meshed with a worm 64. The worm 64 is rotatably connected to the secondary housing 2.

[0040] When the device is deployed, as the secondary housing 2 separates from the main housing 1, the shielding cloth 6 is stretched. The connecting frame 3 and the grid plate 4 that are deployed between the main housing 1 and the secondary housing 2 are covered by the shielding cloth 6. The deployed shielding cloth 6 can be used to mark security warnings or other reasons for setting up roadblocks.

[0041] When storing the device, the worm gear 64 is manually rotated to drive the worm wheel 65 to rotate the winding roller 61 and wind up the shielding cloth 6. During the winding process, the shielding cloth 6 will push the auxiliary box 2 to automatically move closer to the main box 1, which facilitates the storage of the equipment.

[0042] Two guide rollers 63 are symmetrically mounted inside the opening 62 via a damping bearing. The shielding cloth 6 passes between the two guide rollers 63. The guide rollers 63 press and contact the shielding cloth 6, and the shielding cloth 6 is damped and transmitted through the guide rollers 63, so that the unfolded shielding cloth 6 is in a taut state, which facilitates the display of the markings on the surface of the shielding cloth 6.
