Description

Technical Field

[0001] This invention relates to the field of guardrail components, and more particularly to a crash barrier component for buildings. Background Technology

[0002] Crash barriers are mainly used for the protection of buildings such as factories, workshops and warehouses. They are usually made of steel, such as round steel pipes, square steel pipes or profiled steel sheets. With surface treatment processes, the crash barriers are made to be aesthetically pleasing and not easy to rust.

[0003] Existing crash barriers lack internal buffer structures, failing to effectively cushion impacts when struck by external objects, thus easily causing damage. Therefore, prior art CN109236029B discloses a crash barrier for construction sites, comprising: a barrier, two buffer devices, a base, and a detachable device. The barrier is mounted on the base via the detachable device. The barrier has a double-layer structure, including a parallel barrier body and a protective body. The buffer devices are fixed between the barrier body and the protective body. Each buffer device includes two intersecting diagonal bars and two elastic telescopic components. Each elastic telescopic component includes an arc-shaped rod, a locking block, a telescopic spring, and an arc-shaped tube. When impacted by external objects, the buffer devices can buffer part of the impact force, thereby preventing damage to the barrier and providing protection.

[0004] However, the buffer structures on existing crash barriers are relatively simple. When the crash barrier is subjected to a large external impact, it is difficult to effectively buffer the excessive impact, making it difficult to guarantee the lifespan of the crash barrier. Based on the technical problems existing in the background art, the present invention proposes a crash barrier component for buildings. Summary of the Invention

[0005] Based on the technical problems existing in the background art, the present invention proposes a crash barrier component for buildings.

[0006] The present invention proposes a building crash barrier assembly, including a base fixedly disposed on the right outer side of the building, and a first guardrail and a second guardrail respectively fixedly installed on the base, wherein the top of the first guardrail and the second guardrail on the side close to each other are also fixedly connected by a connecting frame.

[0007] A buffer mechanism is provided between the first guardrail and the second guardrail, and a buffer link is movably connected between the first guardrail and the second guardrail through the buffer mechanism. The right end of the buffer link movably extends through to the right side of the first guardrail and is fixedly connected to a crash barrier.

[0008] The buffer mechanism includes a movable frame that is movably installed between the base and the connecting frame, and the movable frame is located between the first guardrail and the second guardrail; a plurality of first buffer springs are fixedly connected between the movable frame and the second guardrail, and the right side of the movable frame is fixedly connected to the left end of the buffer connecting rod; a buffer cavity is provided on the first guardrail, and the buffer connecting rod moves horizontally through the buffer cavity.

[0009] Symmetrically arranged trapezoidal blocks are fixedly connected to the buffer rod located in the buffer cavity. Wedge blocks are movably installed in the buffer cavities located above and below the trapezoidal blocks. The sides of the wedge blocks and trapezoidal blocks that are close to each other are provided with inclined surfaces, and the sides of the wedge blocks and trapezoidal blocks that are close to each other are movably connected to each other through the inclined surfaces. Movable rods are fixedly connected to the sides of the two wedge blocks that are far from each other. Movable cavities are provided on the first guardrails located above and below the buffer cavity. One end of the movable rod movably passes through the movable cavity and is fixedly connected to a movable plate. A buffer spring is fixedly connected between the movable plate and the inner wall of the top side of the buffer cavity. A second buffer spring sleeved on the movable rod is fixedly connected between the wedge block and the inner wall of the top side of the buffer cavity.

[0010] As a further preferred embodiment, the buffer mechanism further includes a buffer hole on the first guardrail, a toothed column that movably passes through the buffer hole, with the left end of the toothed column movably passing through to the left side of the first guardrail and fixedly connected to the movable frame; the right end of the toothed column movably passing through to the right side of the first guardrail and fixedly connected to the crash barrier; the top and bottom inner walls of the buffer hole are respectively provided with rotating grooves, and a wheel axle is fixedly installed in the rotating grooves, with a gear rotatably sleeved on the wheel axle; the top and bottom of the toothed column are provided with tooth grooves, and the toothed column meshes with the gear through the tooth grooves; the gear is provided with a sleeve hole, and the gear is sleeved on the wheel axle through the sleeve hole; a third buffer spring is sleeved on the wheel axle located in the sleeve hole, with one end of the third buffer spring fixedly connected to the wheel axle and the other end of the third buffer spring fixedly connected to the inner wall of the sleeve hole.

[0011] As a further preferred embodiment, multiple anti-collision airbags are also fixedly installed on the right side of the crash barrier, and the multiple anti-collision airbags are evenly and equidistantly arranged.

[0012] As a further preferred embodiment, a first ball bearing is rolled on the inclined surface of the trapezoidal block near the wedge block, and the trapezoidal block is rolledly connected to the inclined surface of the wedge block through the first ball bearing; a second ball bearing is rolled on both sides of the wedge block, and the wedge block is rolledly connected to the inner walls of both sides of the buffer cavity through the second ball bearing.

[0013] As a further preferred embodiment, the inner walls on both sides of the buffer cavity are provided with through holes, and the buffer connecting rod moves through the two through holes.

[0014] As a further preferred embodiment, the buffer spring is specifically in the shape of a "Z" shape, with a first slider on both sides of the movable plate, and a first groove on the inner wall of both sides of the movable cavity, and the first slider is slidably installed in the first groove in the horizontal direction.

[0015] As a further preferred embodiment, the top and bottom of the movable frame are provided with second sliders, the connecting frame and the base are provided with second sliding grooves, and the second sliders are slidably installed in the second sliding grooves along the horizontal direction.

[0016] As a further preferred embodiment, the inner wall of the buffer cavity near the movable cavity is provided with a movable hole, and the movable rod moves through the movable hole.

[0017] The beneficial effects of this invention are:

[0018] In this invention, when the entire guardrail assembly is subjected to a large external impact, the external force will first hit the crash barrier and the crash airbag. In this way, the air pressure inside the crash airbag can be compressed and buffered to absorb energy.

[0019] At the same time, during the collision, the crash barrier and buffer link move to the left to buffer the movement. When the buffer link moves to the left, it also causes the movable frame to move to the left and compress the first buffer spring. In this way, through the compression of the first buffer spring, a portion of the collision impact force can be further consumed.

[0020] Moreover, when the buffer linkage moves to the left, it also causes the trapezoidal block to move to the left, which in turn causes the wedge block to move upward and compress the second buffer spring. At the same time, the wedge block also causes the movable plate to move upward through the movable rod and squeeze the buffer sheet. In this way, through the deformation of the second buffer spring and the buffer sheet, a portion of the excessive impact force can be further offset, thereby further offsetting the excessive external collision impact force.

[0021] At the same time, when the crash barrier moves to the left to buffer, it also causes the tooth column to move to the left. When the tooth column moves to the left, it meshes with the gear through the tooth groove, which in turn causes the gear to rotate. When the gear rotates, it also causes the third buffer spring to twist and deform. In this way, through the deformation of the third buffer spring, the impact of the outside world on the first guardrail, the second guardrail, and the entire guardrail assembly can be further consumed.

[0022] In summary, this building crash barrier component, through the coordinated use of multiple buffer mechanisms, can effectively buffer against excessive external collisions. This avoids the situation where existing crash barriers, due to their relatively simple buffer structures, are prone to damage to the barriers and buildings when subjected to large external impacts. It effectively ensures the overall lifespan of the crash barrier and the building, and its novel structure and good impact buffering effect make it conducive to widespread application.

[0030] The present invention will be further explained below with reference to specific embodiments. Example

[0031] refer to Figure 1-6 In this embodiment, a building crash barrier assembly is proposed, including a base 1 fixedly installed on the right outer side of the building, and a first guardrail 2 and a second guardrail 3 respectively fixedly installed on the base 1, and the top of the first guardrail 2 and the second guardrail 3 on the side close to each other are also fixedly connected by a connecting frame 10.

[0032] A buffer mechanism is provided between the first guardrail 2 and the second guardrail 3, and a buffer link 6 is movably connected between the first guardrail 2 and the second guardrail 3 through the buffer mechanism. The right end of the buffer link 6 movably extends to the right side of the first guardrail 2 and is fixedly connected to the anti-collision railing 5.

[0033] The buffer mechanism includes a movable frame 7 movably installed between the base 1 and the connecting frame 10, and the movable frame 7 is located between the first guardrail 2 and the second guardrail 3; a plurality of first buffer springs 8 are fixedly connected between the movable frame 7 and the second guardrail 3, and the right side of the movable frame 7 is fixedly connected to the left end of the buffer connecting rod 6; the first guardrail 2 is provided with a buffer cavity 201, and the buffer connecting rod 6 moves horizontally through the buffer cavity 201;

[0034] A symmetrically arranged trapezoidal block 11 is fixedly connected to the buffer rod 6 located in the buffer cavity 201. A wedge block 12 is movably installed in the buffer cavity 201 located on the upper and lower sides of the trapezoidal block 11. The sides of the wedge block 12 and the trapezoidal block 11 that are close to each other are provided with inclined surfaces, and the sides of the wedge block 12 and the trapezoidal block 11 that are close to each other are movably connected to each other through the inclined surfaces. A movable rod 14 is fixedly connected to the sides of the two wedge blocks 12 that are far from each other. Movable cavities 202 are provided on the first guardrail 2 located above and below the buffer cavity 201. One end of the movable rod 14 movably passes through the movable cavity 202 and is fixedly connected to a movable plate 15. A buffer spring 16 is fixedly connected between the movable plate 15 and the inner wall of the top side of the buffer cavity 201. A second buffer spring 13 sleeved on the movable rod 14 is fixedly connected between the wedge block 12 and the inner wall of the top side of the buffer cavity 201.

[0035] In this example, the buffer mechanism further includes a buffer hole 203 on the first guardrail 2. A toothed post 9 is movably inserted through the buffer hole 203, with its left end movably extending to the left side of the first guardrail 2 and fixedly connected to the movable frame 7; the right end of the toothed post 9 movably extends to the right side of the first guardrail 2 and is fixedly connected to the crash barrier 5; rotating grooves 204 are respectively provided on the top and bottom inner walls of the buffer hole 203, and a wheel axle 19 is fixedly installed in the rotating groove 204. The moving sleeve is equipped with a gear 18, and the top and bottom of the gear post 9 are provided with tooth grooves 901, and the gear post 9 is engaged with the gear 18 through the tooth grooves 901; the gear 18 is provided with a sleeve hole 181, and the gear 18 is sleeved on the axle 19 through the sleeve hole 181. A third buffer spring 20 is sleeved on the axle 19 located in the sleeve hole 181, and one end of the third buffer spring 20 is fixedly connected to the axle 19, and the other end of the third buffer spring 20 is fixedly connected to the inner wall of the sleeve hole 181.

[0036] In this example, multiple anti-collision airbags 4 are fixedly installed on the right side of the anti-collision barrier 5, and the multiple anti-collision airbags 4 are evenly and equidistantly arranged; a first ball bearing 1101 is rolledly installed on the inclined surface of the trapezoidal block 11 near the wedge block 12, and the trapezoidal block 11 is rolledly connected to the inclined surface on the wedge block 12 through the first ball bearing 1101; a second ball bearing 121 is rolledly installed on both sides of the wedge block 12, and the wedge block 12 is rolledly connected to the inner walls of both sides of the buffer cavity 201 through the second ball bearing 121.

[0037] In this example, the inner walls on both sides of the buffer cavity 201 are provided with through holes, and the buffer connecting rod 6 is movably passed through the two through holes; the buffer spring 16 is specifically in the shape of a "Z"; the two sides of the movable plate 15 are provided with first sliders 17; the inner walls on both sides of the movable cavity 202 are provided with first sliding grooves, and the first sliders 17 are slidably installed in the first sliding grooves in the horizontal direction.

[0038] The movable frame 7 is provided with a second slider at both the top and bottom. The connecting frame 10 and the base 1 are provided with a second sliding groove, and the second slider is slidably installed in the second sliding groove along the horizontal direction. The buffer cavity 201 is provided with a movable hole on the inner wall of the side near the movable cavity 202, and the movable rod 14 is movably inserted through the movable hole.

[0039] like Figure 1-6 As shown, this building crash barrier assembly, during use, is fixedly installed on the right outer side of the building via the base 1. When the entire barrier assembly is subjected to a large external impact, the external force will first impact the crash barrier 5 and the crash airbag 4. The airbag 4 absorbs the energy through compression and cushioning. Simultaneously, during the impact, the crash barrier 5 and the buffer link 6 move to the left for cushioning. The leftward movement of the buffer link 6 also causes the movable frame 7 to move to the left and compress the first buffer spring 8. By compressing and buffering the first buffer spring 8, a portion of the impact force can be further consumed. Moreover, when the buffer linkage 6 moves to the left, it also drives the trapezoidal block 11 to move to the left, thereby causing the wedge block 12 to move upward and compress the second buffer spring 13. At the same time, the wedge block 12 also drives the movable plate 15 to move upward through the movable rod 14 and squeeze the buffer spring 16. In this way, through the deformation of the second buffer spring 13 and the buffer spring 16, a portion of the excessive impact force can be further offset, thereby further offsetting the excessive impact force from the outside.

[0040] Meanwhile, when the crash barrier 5 moves to the left to buffer the impact, it also causes the toothed column 9 to move to the left. When the toothed column 9 moves to the left, it meshes with the gear 18 through the tooth groove 901, which in turn causes the gear 18 to rotate. When the gear 18 rotates, it also causes the third buffer spring 20 to twist and deform. In this way, the deformation of the third buffer spring 20 can further absorb the impact of the outside world on the first guardrail 2, the second guardrail 3, and other guardrail components. Finally, through the cooperation of multiple buffer mechanisms, this invention can effectively buffer against excessive external collision impacts, avoiding the situation where the buffer structure set on the existing crash barriers is relatively simple, and the guardrail and building are easily damaged once subjected to a large external collision impact. This effectively ensures the overall lifespan of the crash barrier and the building. Moreover, the structure is novel, the impact buffer effect is good, and it is conducive to widespread application.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
