Description

Technical Field

[0001] The utility model relates to the technical field of enclosures, in particular to a safety enclosure device for road and bridge engineering. Background Art

[0002] In the process of modern road and bridge construction, safety fencing is needed, which refers to the measures taken to isolate the construction site from the external environment and make the construction site a relatively closed space. Safety fencing plays an important and wide-ranging role.

[0003] However, some road and bridge engineering safety fences are too large when not in use, occupying a large amount of space. They are inconvenient to carry during transportation and are not easy to carry. At the same time, it is not easy to fix the safety fence during installation, which brings inconvenience to users. For this reason, we propose a road and bridge engineering safety fence device to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a road and bridge engineering safety enclosure device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a road and bridge engineering safety enclosure device comprises a baffle, both sides of the baffle are provided with rectangular grooves, side panels are slidably connected in the rectangular grooves, the top of the side panel is provided with a groove, four vertical blocks are fixedly connected to the bottom inner wall of the groove, the top of the vertical block is fixedly connected to a first triangular block, the same second triangular block is movably mounted between the corresponding two first triangular blocks, the top of the second triangular block is fixedly connected to a round rod, the top of the round rod extends to the top of the baffle and is fixedly connected to a pull block, the baffle is slidably sleeved on the outside of the round rod, the bottom of the side panel is provided with a square groove, the top inner wall of the square groove is rotatably connected to a screw, the outer thread sleeve of the screw is provided with an insertion rod, the top of the screw extends to the top of the corresponding side panel and is fixedly connected to a knob.

[0006] Further preferably, the bottom end of the insertion rod extends to below the corresponding side plate, and a transverse block is fixedly connected to the outer side of the round rod.

[0007] Further preferably, a positioning rod is fixedly connected to the top inner wall of the rectangular groove, and the horizontal block is slidably sleeved on the outer side of the positioning rod.

[0008] Further preferably, a same spring is fixedly connected between the top of the horizontal block and the top inner wall of the corresponding groove.

[0009] Further preferably, the spring is movably sleeved on the outer side of the corresponding positioning rod, and sliding grooves are provided on the inner walls on both sides of the square groove.

[0010] Further preferably, both sides of the insertion rod are fixedly connected with sliders, and the sliders are slidably connected to the corresponding sliding grooves.

[0011] Further preferably, a connecting plate is fixedly connected to the bottom of the side plate, and a roller is rotatably connected to the bottom of the connecting plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows: the side panels of the utility model are stored in the rectangular groove, which reduces the overall volume and is easy to carry. Holding the side panel and moving it outward causes the inclined surface of the first triangular block to squeeze the inclined surface of the second triangular block and compress the spring. The side panel is continued to be moved, and similarly the second triangular block can be clamped between the other two first triangular blocks in the groove. The side panel is fixed, and the safety fence isolates the road and bridge construction site from the external environment. Turning the knob drives the insertion rod to move downward and insert it into the soil through the screw, so that after the safety fence is used, the overall volume can be reduced, does not occupy a large amount of space, is easy to carry, and is easy to fix the safety fence on the ground, which brings convenience to the user.

The side panel 3 is stored in the rectangular groove 2, which reduces the overall volume and is easy to carry. The side panel 3 is held and moved outward so that the inclined surface of the first triangular block 6 presses the inclined surface of the second triangular block 7 and compresses the spring 16. The side panel 3 continues to be moved. Similarly, the second triangular block 7 can be clamped between the other two first triangular blocks 6 in the groove 4. The side panel 3 is fixed, and the safety fence isolates the road and bridge construction site from the external environment. Turning the knob 13 drives the insertion rod 12 to move downward and insert it into the soil through the screw 11, so that the safety fence can reduce the overall volume after use, does not take up a lot of space, is easy to carry, and is easy to fix the safety fence on the ground, which brings convenience to the user.

[0021] In this embodiment, specifically: the bottom end of the insertion rod 12 extends to the bottom of the corresponding side plate 3, and the outer side of the round rod 8 is fixedly connected with a horizontal block 14;

[0022] In this embodiment, specifically: a positioning rod 15 is fixedly connected to the top inner wall of the rectangular groove 2, and the horizontal block 14 is slidably sleeved on the outer side of the positioning rod 15;

[0023] In this embodiment, specifically: a spring 16 is fixedly connected between the top of the horizontal block 14 and the top inner wall of the corresponding groove 4;

[0024] In this embodiment, specifically: the spring 16 is movably sleeved on the outer side of the corresponding positioning rod 15, and the inner walls on both sides of the square groove 10 are provided with a slide groove 17, and the setting of the slide groove 17 plays a positioning effect;

[0025] In this embodiment, specifically: both sides of the insertion rod 12 are fixedly connected with a slider 18, and the slider 18 is slidably connected with the corresponding slide groove 17;

[0026] In this embodiment, specifically: a connecting plate 19 is fixedly connected to the bottom of the side plate 3 , and a roller 20 is rotatably connected to the bottom of the connecting plate 19 .

[0027] The utility model is in operation: when in use, the side panels 3 are stored in the rectangular grooves 2, thereby reducing the overall volume and being easy to carry and transport. When the side panels 3 need to be pulled out from the corresponding rectangular grooves 2, the road and bridge construction site is isolated from the external environment by the safety enclosure, making the construction site a relatively closed space. The side panels 3 are held and moved outward, and the side panels 3 drive the first triangular blocks 6 to move through the vertical blocks 5. At this time, the inclined surface of the first triangular block 6 squeezes the inclined surface of the second triangular block 7. Under the action of the squeezing force, the second triangular block 7 drives the corresponding round rod 8 to move upward, and the round rod 8 drives the horizontal block 14 to slide on the outside of the positioning rod 15 and compress the spring 16, and continues to move the side panels 3. Similarly, the first triangular block 6 is moved upward. The second triangular block 7 can be clamped between the other two first triangular blocks 6 in the groove 4, so that the side panel 3 is fixed. When the two side panels 3 and the baffle 1 need to be fixed on the ground, the knob 13 is turned, and the knob 13 drives the corresponding screw 11 to rotate. The rotation of the screw 11 drives the insertion rod 12 to move downward, and the insertion rod 12 drives the slider 18 to slide in the corresponding slide groove 17, so that the insertion rod 12 moves downward and is inserted into the soil, so that the side panel 3 and the baffle 1 are fixed on the ground, thereby forming a road and bridge engineering safety enclosure device, so that the safety enclosure can reduce the overall volume after use, does not occupy a large amount of space, is easy to carry, and is easy to fix the safety enclosure on the ground, which brings convenience to users.
