When the first rotating plate and the second rotating plate are outturned to expand, the clamping mechanism is used to clamp the sliding seat on another first rotating plate, so that multiple groups of the first rotating plate and the second rotating plate are connected with each other to form a blocking fence.

Description

Technical Field

[0001] This invention relates to the field of road and bridge construction warning technology, specifically a road and bridge construction warning structure. Background Technology

[0002] Roads and bridges are the infrastructure for modern travel, ensuring smooth and safe daily travel. During road and bridge construction and inspection and maintenance, warning signs are often used as traffic safety warning devices. They are placed in the middle of the road, in dangerous areas and road construction sites to remind pedestrians and vehicles to stay away from danger.

[0003] Existing warning signs used during road and bridge construction or maintenance can only serve a single warning function and cannot effectively block off or cordon off the site. Therefore, we propose a new warning structure for road and bridge construction. Summary of the Invention

[0004] One of the technical problems this application aims to solve is: how to make warning signs both serve as a warning and as a barrier to block off the site.

[0005] To address the aforementioned technical problems, this application provides a road and bridge construction warning structure, including a first rotating plate, on which a second rotating plate is rotatably mounted, and further comprising:

[0006] A limiting mechanism is used to limit and support the angle of the first rotating plate and the second rotating plate during manual rotation, so that the first rotating plate and the second rotating plate can be rotated inward and retracted to be used as a warning sign, and is set on the first rotating plate.

[0007] The sliding seat is slidably mounted on the first rotating plate;

[0008] A locking mechanism is used to lock onto a sliding seat on another first rotating plate after the first and second rotating plates have rotated outwards and expanded, so that multiple sets of the first and second rotating plates are connected to each other to form a blocking line, and is disposed on the second rotating plate.

[0009] In some embodiments, the limiting mechanism includes a ratchet disposed on a first rotating plate, a fixed rod disposed on the second rotating plate, a pawl rotatably disposed on the fixed rod, and a torsion spring disposed between the pawl and the fixed rod;

[0010] The second rotating plate is provided with a pushing component, which is used to drive the pawl to disengage from the ratchet, so that after the first rotating plate and the second rotating plate rotate outward to expand, they can rotate in opposite directions to retract.

[0011] The first rotating plate is provided with two support components, which are used to provide auxiliary support for the first rotating plate and the second rotating plate during rotation.

[0012] In some embodiments, the pushing assembly includes a fixed cylinder disposed on a second rotating plate, one end of the fixed cylinder being provided with a pushing post, and the other end of the fixed cylinder being provided with a pressing rod;

[0013] The pressing rod is provided with a displacement component, which is used to drive the push post to rotate the pawl after the pressing rod is manually driven to move, thereby disengaging it from the ratchet.

[0014] The displacement member is provided with a locking member, which is used to limit the position of the push post and drive the push post to reset.

[0015] In some embodiments, the displacement member includes a displacement groove column disposed on the pressing rod, a first spring disposed on the displacement groove column, a displacement cylinder sleeved between the fixed cylinder and the pressing rod, and the displacement cylinder being connected to the pushing column.

[0016] In some embodiments, the locking member includes an elastic locking strip disposed on the displacement cylinder, one end of the elastic locking strip being connected to the push post, the other end of the elastic locking strip being provided with a groove plate, the fixed cylinder being provided with a locking groove matching the elastic locking strip, and a second spring being sleeved on the push post.

[0017] In some embodiments, the support assembly includes a rotating rod rotatably disposed on a first rotating plate, a rotating sleeve rotatably disposed on a second rotating plate, the rotating rod being slidably disposed within the rotating sleeve, and a third spring being disposed between the rotating rod and the rotating sleeve.

[0018] In some embodiments, the snap-fit ​​mechanism includes a fixed plate disposed on a first rotating plate, a fourth spring disposed between the fixed plate and the sliding seat, two through holes disposed on the fixed plate, a wedge block disposed on one side of the second rotating plate, and two snap pins disposed on one side of the second rotating plate;

[0019] The second rotating plate is provided with a driving component for manually driving the wedge block to move in the horizontal direction and limiting its position;

[0020] The driving component is provided with a reversing component, which is used to convert the horizontal displacement of the wedge block into the vertical displacement of the two locking pins, so that the two locking pins engage with the two through holes.

[0021] In some embodiments, the driving member includes a fixed seat disposed on a second rotating plate, a push plate rotatably disposed on the fixed seat, a sliding column slidably disposed on the fixed seat, a connecting block disposed on the sliding column, a connecting rod disposed on the connecting block, the connecting rod slidably disposed on the fixed seat, a fifth spring sleeved on the connecting rod, and the wedge block connected to the connecting rod.

[0022] In some embodiments, the deflector includes a mounting base disposed on a fixed base, two inclined blocks are symmetrically disposed on both sides of the wedge block, the two inclined blocks are respectively connected to two locking posts, and a sixth spring is sleeved on each of the two locking posts.

[0023] In some embodiments, the connecting block is provided with a slot, through which the push plate passes.

[0024] The present invention has at least the following beneficial effects:

[0025] Unlike existing technologies, this road and bridge construction warning structure allows workers to use the limiting mechanism to manually drive the rotation of the first and second rotating plates, limiting and supporting their angles. This allows the first and second rotating plates to retract inwards and function as warning signs. The locking mechanism then engages with a sliding seat on another first rotating plate after the first and second rotating plates have expanded outwards, connecting multiple sets of the first and second rotating plates to form a barrier.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0041] Please see Figure 1-12 The present invention provides a technical solution:

[0042] A road and bridge construction warning structure includes a first rotating plate 1, a second rotating plate 2 rotatably mounted on the first rotating plate 1, and further includes:

[0043] The limiting mechanism 3 is used to limit and support the angle of the first rotating plate 1 and the second rotating plate 2 during the manual rotation process, so that the first rotating plate 1 and the second rotating plate 2 can be rotated inward and retracted to be used as a warning sign, and is set on the first rotating plate 1.

[0044] Sliding seat 4 is slidably mounted on the first rotating plate 1;

[0045] The locking mechanism 5 is used to lock onto the sliding seat 4 on another first rotating plate 1 after the first rotating plate 1 and the second rotating plate 2 have rotated outward and expanded, so that multiple sets of first rotating plates 1 and second rotating plates 2 are connected to each other to form a blocking line, and is set on the second rotating plate 2.

[0046] The limiting mechanism 3 includes a ratchet 31 mounted on the first rotating plate 1, a fixed rod 32 mounted on the second rotating plate 2, a pawl 33 rotatably mounted on the fixed rod 32, and a torsion spring 34 between the pawl 33 and the fixed rod 32. Due to the engagement of the pawl 33 and the ratchet 31, the first rotating plate 1 and the second rotating plate 2 can only rotate inward and retract. When the angle between the first rotating plate 1 and the second rotating plate 2 is less than 90 degrees, their sides can be supported on the ground. Warning content can be printed on the surfaces of the first rotating plate 1 and the second rotating plate 2 for use as warning signs.

[0047] The second rotating plate 2 is provided with a pushing component 6, which is used to drive the pawl 33 to disengage from the ratchet 31, so that the first rotating plate 1 and the second rotating plate 2 can rotate in opposite directions to retract after expanding outward. The pushing component 6 includes a fixed cylinder 61 provided on the second rotating plate 2. One end of the fixed cylinder 61 is provided with a pushing post 62, and the other end of the fixed cylinder 61 is provided with a pressing rod 63. The fixed cylinder 61 is fixedly provided on the second rotating plate 2.

[0048] The pressing rod 63 is equipped with a displacement component 8, which, after the pressing rod 63 is manually moved, drives the push post 62 to push the pawl 33 to rotate and disengage from the ratchet 31. The displacement component 8 includes a displacement groove post 81 on the pressing rod 63, a first spring 82 on the displacement groove post 81, and a displacement cylinder 83 sleeved between the fixed cylinder 61 and the pressing rod 63. The displacement cylinder 83 is connected to the push post 62. Pressing the pressing rod 63 causes the displacement groove post 81 to move, the first spring 82 is compressed, and the displacement cylinder 83 and the push post 62 are pushed to move. The push post 62 pushes the pawl 33 to rotate and disengage from the ratchet 31. At this time, the first rotating plate 1 and the second rotating plate 2 can rotate outward in opposite directions to expand and change their angle.

[0049] A locking element 9 is provided on the displacement cylinder 83 to limit the position of the push post 62 and drive it to reset. The locking element 9 includes an elastic retaining strip 91 on the displacement cylinder 83. One end of the elastic retaining strip 91 is connected to the push post 62, and the other end of the elastic retaining strip 91 is provided with a groove plate 92. The fixed cylinder 61 is provided with a groove 93 that matches the elastic retaining strip 91. A second spring 94 is sleeved on the push post 62. The displacement cylinder 83 drives the elastic retaining strip 91 and the groove plate 92 to move, and the elastic retaining strip 91 and the groove 93 engage, thereby limiting the position of the push post 62. Pressing the pressing rod 63 again causes the displacement groove post 81 to move slightly. The arc-shaped end face of 81 contacts the groove plate 92, pushing the groove plate 92 and the elastic locking strip 91 to move away from the groove 93. The elastic locking strip 91 is released from the groove 93. Under the action of the second spring 94 and the first spring 82, the pressing rod 63 and the pushing post 62 return to the initial position. The pushing post 62 no longer pushes the pawl 33, and the pawl 33 is locked with the ratchet 31 again. By changing the position of the pushing post 62, when the pushing post 62 does not push the pawl 33, the first rotating plate 1 and the second rotating plate 2 can rotate inward to retract. When the pushing post 62 pushes the pawl 33, the first rotating plate 1 and the second rotating plate 2 can rotate outward in the opposite direction to expand.

[0050] Two support assemblies 7 are provided on the first rotating plate 1 to provide auxiliary support for the first rotating plate 1 and the second rotating plate 2 during rotation. The support assembly 7 includes a rotating rod 71 rotatably mounted on the first rotating plate 1 and a rotating sleeve 72 rotatably mounted on the second rotating plate 2. The rotating rod 71 is slidably mounted inside the rotating sleeve 72, and a third spring 73 is provided between the rotating rod 71 and the rotating sleeve 72. During the rotation of the first rotating plate 1 and the second rotating plate 2, the rotating rod 71 slides inside the rotating sleeve 72, and the third spring 73 is compressed or stretched accordingly. The rotating rod 71 and the rotating sleeve 72 provide auxiliary support for the first rotating plate 1 and the second rotating plate 2.

[0051] The locking mechanism 5 includes a fixed plate 51 disposed on the first rotating plate 1, a fourth spring 52 disposed between the fixed plate 51 and the sliding seat 4, two through holes 53 disposed on the fixed plate 51, a wedge block 54 disposed on one side of the second rotating plate 2, and two locking pins 55 disposed on one side of the second rotating plate 2; a driving member 10 is disposed on the second rotating plate 2 for manually driving the wedge block 54 to move horizontally and limiting its position; the driving member 10 includes a fixed seat 101 disposed on the second rotating plate 2, and a push plate 1 is rotatably disposed on the fixed seat 101. 02. A sliding column 103 is slidably disposed on the fixed base 101. A connecting block 104 is disposed on the sliding column 103. A connecting rod 105 is disposed on the connecting block 104. The connecting rod 105 is slidably disposed on the fixed base 101. A fifth spring 106 is sleeved on the connecting rod 105. The wedge block 54 is connected to the connecting rod 105. Pushing the connecting block 104 causes the sliding column 103, the connecting rod 105 and the wedge block 54 to move in the horizontal direction. Rotating the push plate 102 causes it to contact and push the connecting block 104, thereby limiting the position of the wedge block 54.

[0052] A deflector 11 is provided on the fixed base 101 to convert the horizontal displacement of the wedge block 54 into the vertical displacement of the two locking pins 55, so that the two locking pins 55 engage with the two through holes 53. The deflector 11 includes a mounting base 111 provided on the fixed base 101. Two inclined blocks 112 are symmetrically arranged on both sides of the wedge block 54. The two inclined blocks 112 are respectively connected to the two locking pins 55. A sixth spring 113 is sleeved on each of the two locking pins 55. The displacement of the wedge block 54 pushes the two inclined blocks 112 to move outward, thereby driving the two locking pins 55 to move outward synchronously and engage with the two through holes 53.

[0053] In use, warning messages can be printed on the surfaces of the first rotating plate 1 and the second rotating plate 2. Due to the engagement of the pawl 33 and the ratchet 31, the first rotating plate 1 and the second rotating plate 2 can only rotate inward to retract. After the push post 62 pushes the pawl 33 to rotate and disengage from the ratchet 31, the first rotating plate 1 and the second rotating plate 2 can rotate outward in the opposite direction to expand and change their angle. When used as a warning sign, the angle between the first rotating plate 1 and the second rotating plate 2 should be less than 90 degrees, and their sides should be able to support them on the ground. In this case, they can be used as a warning sign. When it is necessary to form a barrier, the first rotating plates 1 and the second rotating plates 2 in the same group should form a 180-degree angle. Multiple groups of first rotating plates 1 and... The second rotating plate 2 is placed in sequence, pushing the sliding seat 4 on the other set of first rotating plates 1 to approach the two locking posts 55 on the first set of second rotating plates 2. The connecting block 104 is pushed to drive the sliding post 103, connecting rod 105 and wedge block 54 to move in the horizontal direction. The push plate 102 is rotated to make it contact the pushing connecting block 104, thereby limiting the position of the wedge block 54. During this process, the displacement of the wedge block 54 pushes the two inclined blocks 112 to move outward, and drives the two locking posts 55 to move outward synchronously, and locks them with the two through holes 53 on the other set of first rotating plates 1. Thus, multiple sets of first rotating plates 1 and second rotating plates 2 can be connected to each other to form a blockage. Example 2

[0054] Please see Figure 1-13 The present invention provides a technical solution:

[0055] Unlike Embodiment 1, the connecting block 104 is provided with a slot 12, through which the push plate 102 passes. The push plate 102 can pass through the slot 12 to prevent the push plate 102 from rotating arbitrarily when it does not push the connecting block 104, thus affecting the movement and stacking of the first rotating plate 1 and the second rotating plate 2.
