A blocking assembly is fixedly mounted on one end of each of the multiple first ropes, and two third ropes, respectively fixedly connected to the two winding assemblies, are fixedly mounted on both ends of the blocking assembly. Four clamping bars for holding the winding assemblies are slidably configured inside the fixed frame, and a fixing block is fixedly mounted on each of the four clamping bars. A pressing block for pressing the four fixing blocks is fixedly mounted on the output ends of the two electric push rods, and two springs are fixedly mounted between adjacent clamping bars.

[0007] Preferably, four guide rods are fixedly installed on both sides of the fixed frame, each penetrating one of the four clamping bars. Four springs are respectively sleeved on the periphery of the four guide rods. The installation of the springs facilitates pushing the two clamping bars to slide away from each other and reset.

[0008] Preferably, two sealing shells are fixedly installed on both sides of the fixed frame, the winding assembly includes multiple barrier bars arranged sequentially up and down, multiple second ropes are arranged between two adjacent barrier bars, and two rotating wheels corresponding to two third ropes are fixedly installed at the bottom of the fixed frame. The installation of the rotating wheels facilitates the winding wheels to wind up the third ropes.

[0009] Preferably, the winding assembly includes a first motor fixedly mounted on a fixed frame and a winding wheel fixedly mounted on the output end of the first motor. The two winding wheels are respectively fixedly connected to one end of two third ropes. The installation of the winding wheels facilitates the winding and coiling of the third ropes.

[0010] Preferably, the two ends of the plurality of barrier bars are slidably fitted on the two inner sides of the fixed frame, and the barrier assembly is wrapped around the periphery of the winding bar. The installation of the barrier bars can block and protect pedestrians.

Detailed Implementation

[0024] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figure 1-6As shown, this utility model embodiment provides a protective device, including: a fixed frame 1, on which two winding components 2, an electric push rod 3, and a second motor 19 are fixedly installed. A winding rod 4 is fixedly installed on the output end of the second motor 19. Multiple first ropes 5 are fixedly installed on the winding rod 4. A blocking component 6 is fixedly installed at one end of the multiple first ropes 5. Two third ropes 7, respectively fixedly connected to the two winding components 2, are fixedly installed at both ends of the blocking component 6. Four clamping bars 8 are slidably arranged inside the fixed frame 1 to clamp the winding components 2. A fixing block 9 is fixedly installed on each of the four clamping bars 8. A pressing block 10 is fixedly installed on the output end of the two electric push rods 3 to press the four fixing blocks 9. Two springs 11 are fixedly installed between two adjacent clamping bars 8.

[0027] In this embodiment, specifically: four guide rods 12, each penetrating one of the four clamping bars 8, are fixedly installed on both sides of the fixed frame 1. Four springs 11 are respectively sleeved on the periphery of the four guide rods 12. The installation of the guide rods 12 can guide the clamping bars 8 during the sliding process, thereby making the clamping bars 8 slide more smoothly.

[0028] In this embodiment, specifically: two sealing shells 13 are fixedly installed on both sides of the fixed frame 1; the winding assembly 2 includes multiple barrier bars 14 arranged sequentially up and down; multiple second ropes 15 are arranged between two adjacent barrier bars 14; two rotating wheels 16 are fixedly installed at the bottom of the fixed frame 1, which correspond to two third ropes 7 respectively; the installation of the second ropes 15 facilitates the mutual fixation between the multiple barrier bars 14.

[0029] In this embodiment, specifically: the winding component 2 includes a first motor 16 fixedly installed on the fixed frame 1 and a winding wheel 17 fixedly installed on the output end of the first motor 16. The two winding wheels 17 are respectively fixedly connected to one end of two third ropes 7. The installation of the third ropes 7 facilitates the tightening of the blocking component 6 and facilitates the unfolding of the blocking component 6 after it is tightened.

[0030] In this embodiment, specifically: the two ends of multiple blocking rods 14 are slidably fitted on the two inner sides of the fixed frame 1, the blocking component 6 is wound around the periphery of the winding rod 4, and the installation of the winding rod 4 facilitates the winding of the blocking component 6.

[0031] In this embodiment, specifically: four clamping strips 8 are respectively clamped at both ends of multiple blocking bars 14, both sides of the four fixing blocks 9 are inclined, the two inner sides of the two squeezing blocks 10 are respectively attached to the two sides of the four fixing blocks 9, and four guide strips 18 are fixedly installed on both sides of the fixing frame 1 to guide the two squeezing blocks 10 respectively. The installation of the squeezing blocks 10 can squeeze the fixing blocks 9, so that the fixing blocks 9 can be squeezed and drive the clamping strips 8 to clamp and fix the blocking bars 14.

[0032] When this utility model is in operation: when the blocking component 6 in the device needs to be unfolded to block and protect pedestrians, the second motor 19 is turned on. The second motor 19 drives the winding rod 4 to rotate, and the rotation of the winding rod 4 drives the blocking component 6 to unfold. At this time, the blocking component 6 wound on the winding rod 4 unfolds. After the blocking component 6 unfolds, the blocking rods 14 are set up and down in sequence to block pedestrians. During the unfolding process of the blocking component 6, the first motor 16 needs to be turned on. The first motor 16 drives the winding wheel 17 to rotate, and the rotation of the winding wheel 17 winds up the third rope 7. After the third rope 7 is wound up, the blocking component 6 gradually unfolds.

[0033] When the clamping bar 8 needs to clamp and fix the barrier bar 14, the two electric push rods 3 are activated. The activation of the electric push rods 3 causes the squeezing block 10 to slide. The sliding of the squeezing block 10 causes the two fixing blocks 9 and the clamping bar 8 to slide closer to each other. After the two clamping bars 8 slide closer to each other, they clamp and fix the barrier bar 14. At this time, the barrier bar 14 is not easy to shake.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
