Description

Technical Field

[0001] This utility model relates to the field of guardrail technology, and in particular to a crash barrier that is easy to assemble and disassemble. Background Technology

[0002] Guardrails are structures used for protection, isolation, or guidance. They are usually made of materials such as metal, wood, plastic, or concrete. They are often installed on roads, stairs, balconies, bridges, etc., to improve safety and prevent people or objects from falling or entering dangerous areas. In addition, guardrails can also beautify the environment and serve a decorative purpose. Depending on the purpose, guardrails come in various types and designs, such as road guardrails, landscape guardrails, and industrial guardrails, with road guardrails being the most common type.

[0003] The patent number "CN222251863U" discloses a "road safety crash barrier that is easy to disassemble and assemble." This device works by pressing a pressure plate, which causes a locking block to move downwards. During the downward movement of the pressure plate, a spring is compressed, and the pressure plate disengages from the locking hole, allowing the first guardrail and the first crash bar to separate. After releasing the pressure plate, the spring rebounds, and the locking block automatically resets, facilitating assembly during use. Existing guardrails are generally designed as a single unit, requiring the replacement of the entire guardrail when a part is damaged, resulting in low reuse rate. In addition, the middle part of the small square post of the guardrail is the most vulnerable part to breakage during actual use, but the small square post of the existing guardrail is still a bare pole structure, resulting in low impact resistance. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned problems by proposing a crash barrier that is easy to assemble and disassemble. It improves the existing barrier design, which is generally an integrated structure. When the barrier is partially damaged, the entire barrier needs to be replaced, resulting in low reuse rate. At the same time, the middle part of the small square post of the barrier is the most vulnerable part of the barrier and is most easily damaged in actual use. However, the small square post of the existing barrier is still a bare pole structure design, which has low impact resistance.

[0005] A crash barrier that is easy to assemble and disassemble includes a column body, small square posts, a portable assembly mechanism, a positioning assembly mechanism, and an impact protection mechanism: the column body in the same group is provided in two sets, and multiple sets of small square posts are installed at equal intervals between the two sets of column bodies, and the small square posts are all set in an "I" shape.

[0006] The portable assembly mechanism includes a first crossbeam, a second crossbeam, and auxiliary positioning blocks. The first crossbeam and the second crossbeam are connected and installed from top to bottom between the inner side walls of the two column bodies in the same group. The bottom outer wall of the first crossbeam and the top outer wall of the second crossbeam are provided with auxiliary positioning blocks at equal intervals. There are two auxiliary positioning blocks in the same group facing each other, and both auxiliary positioning blocks are set as horizontal "L" shaped structures.

[0007] Preferably, the top outer wall of the small square column is provided with a cylindrical groove, the top outer wall of the first crossbeam is provided with a cylindrical insertion groove corresponding to the cylindrical groove, an insertion column is slidably installed inside the cylindrical groove, the bottom outer wall of the insertion column is provided with a threaded column, and the top outer wall of the second crossbeam is provided with a cylindrical threaded groove that is threadedly installed with the threaded column.

[0008] Preferably, the rotating end of the plug is located above the first crossbeam, and the rotating end of the plug is provided with vertical anti-slip texture.

[0009] Preferably, the positioning assembly mechanism includes a support block, a support back plate, an abutment block, and an abutment slot. Two sets of support blocks are symmetrically arranged on the outer side walls of the two sets of small square columns located at the edge. Four sets of support blocks are arranged on the same side, and the support back plate is located in the middle of the four sets of support blocks. Two sets of abutment blocks are symmetrically arranged on the outer side walls of the two sides of the support back plate, and an abutment slot is correspondingly opened on the top outer wall of the support block for insertion and installation of the abutment block.

[0010] Preferably, the support block has a first threaded groove through the outer wall of its side at the position of the contact slot, and the corresponding outer wall of the contact block has a second threaded groove through the outer wall. The first and second threaded grooves are threadedly connected to the fastening bolt.

[0011] Preferably, the impact protection mechanism includes a limiting cylinder, a limiting piston rod, a support spring, and a protective outer plate. Three sets of limiting cylinders are evenly spaced on the outer side wall of the support back plate away from the small square column. The limiting piston rod is slidably installed inside the limiting cylinder, and a support spring is installed between the outer side wall of the limiting piston rod and the inner bottom wall of the limiting cylinder. The protruding end of the limiting piston rod is located outside the limiting cylinder, and the protruding end of the limiting piston rod is connected to the inner side wall of the protective outer plate.

[0012] Preferably, the protective outer panel is configured as a transverse "U" shaped structure, and the protective outer panel is slidably installed on the outside of the supporting back panel, with an elastic protective pad embedded in the outer side wall of the protective outer panel.

[0013] Preferably, the limiting cylinder is filled with damping fluid, and the side outer wall of the limiting piston rod located at the piston disc position is provided with through holes at equal intervals for the flow of damping fluid.

[0014] The beneficial effects of this utility model are:

[0015] 1. This easy-to-assemble and disassemble crash barrier features an "I"-shaped structure for the small square posts, which are designed to be detachable. When the barrier is damaged during actual use, the damaged small square posts can be directly removed and replaced with new ones. If other components are damaged, the damaged small square posts can be removed and installed into the new barrier. The overall system has a high rate of sustainable use and does not require the entire barrier to be discarded due to partial damage. It is highly practical.

[0016] 2. This easily assembled and disassembled crash barrier utilizes a design that incorporates a crash buffer assembly on the side of the small square posts, which are most vulnerable to damage. The design employs an elastic protective pad for primary buffering, while the incompressibility of the liquid, combined with the movement of a piston assembly, creates resistance as the damping fluid is compressed. This resistance hinders the rapid movement of the piston, slowing down the impact and reducing its energy. This dual buffering design ensures that the small square posts on the side of the barrier are protected from external impacts, preventing damage. The overall design is ingenious and highly effective.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In practical implementation: such as Figure 1-6 As shown, a crash barrier that is easy to assemble and disassemble includes a column body 1, small square columns 2, a portable assembly mechanism 3, a positioning assembly mechanism 4, and an impact protection mechanism 5: two sets of column bodies 1 are provided in the same group, and multiple sets of small square columns 2 are installed at equal intervals between the two sets of column bodies 1, and the small square columns 2 are all set as "I" shaped structures.

[0026] The portable assembly mechanism 3 includes a first crossbeam 31, a second crossbeam 32, and auxiliary positioning blocks 33. The first crossbeam 31 and the second crossbeam 32 are connected and installed from top to bottom between the inner side walls of the two column bodies 1 in the same group. The bottom outer wall of the first crossbeam 31 and the top outer wall of the second crossbeam 32 are provided with auxiliary positioning blocks 33 at equal intervals. There are two auxiliary positioning blocks 33 in the same group facing each other, and both auxiliary positioning blocks 33 are set as horizontal "L" shaped structures. The top outer wall of the small square column 2 is provided with a columnar groove 34. The top outer wall of the first crossbeam 31 is provided with a columnar insertion groove that is opposite to the columnar groove 34. An insertion post 35 is slidably installed inside the columnar groove 34. The bottom outer wall of the insertion post 35 is provided with a threaded post 36. The top outer wall of the second crossbeam 32 is provided with a columnar threaded groove 37 that is threadedly installed with the threaded post 36.

[0027] When the entire device needs to be assembled and placed in a designated location, the first step is to place the two sets of upright bodies 1 on the ground according to the predetermined placement position. Here, the first crossbeam 31 and the second crossbeam 32, together with the two sets of upright bodies 1, form a complete frame structure. Then, the small square columns 2 are sequentially arranged and installed in the middle position between the first crossbeam 31 and the second crossbeam 32. During installation, the small square columns 2 are first pushed horizontally to the middle position of the two auxiliary positioning blocks 33 in the same group. Then, through the combined limiting action of the upper and lower sets of auxiliary positioning blocks 33, the small square columns 2 can be accurately positioned in the middle position between the first crossbeam 31 and the second crossbeam 32. The limiting principle here is based on the two sets of auxiliary blocks 33. The positioning blocks 33 together form a limiting range to limit the top and bottom of the "I"-shaped small square column 2. Then, the plug-in column 35 is passed vertically downward through the cylindrical plug-in groove above the first crossbeam 31 and into the interior of the cylindrical groove 34. When the plug-in column 35 reaches the bottom of the cylindrical groove 34, the plug-in column 35 is rotated to screw the threaded column 36 at its bottom end into the cylindrical threaded groove 37 to complete the installation process of a single set of small square columns 2. The installation and disassembly of other sets of small square columns 2 are the same. However, it should be noted that the two sets of small square columns 2 with support blocks 41 on their outer walls need to be installed at the outermost edge of the device to facilitate the installation of the support back plate 42 described below.

[0028] The rotating end of the plug 35 is located above the first crossbeam 31, and the rotating end of the plug 35 is provided with vertical anti-slip texture; this design allows the user to rotate the plug 35 more stably and smoothly.

[0029] The positioning assembly mechanism 4 includes a support block 41, a support back plate 42, an abutment block 43, and an abutment groove 44. Two sets of support blocks 41 are symmetrically arranged on the outer side walls of the two sets of small square columns 2 located at the edge. Four sets of support blocks 41 are arranged on the same side. The support back plate 42 is located in the middle of the four sets of support blocks 41. Two sets of abutment blocks 43 are symmetrically arranged on the outer side walls of the two sides of the support back plate 42. The top outer wall of the support block 41 is correspondingly provided with an abutment groove 44 that is inserted and installed in accordance with the abutment block 43. A first threaded groove 45 is provided through the outer side wall of the support block 41 located at the abutment groove 44. A second threaded groove 46 is provided through the outer side wall of the abutment block 43. The first threaded groove 45 and the second threaded groove 46 are threadedly installed with the fastening bolt 47.

[0030] After the entire frame of the above-mentioned column body 1, small square column 2, first crossbeam 31 and second crossbeam 32 is assembled, the support back plate 42 needs to be adjusted to a suitable position and its side abutment block 43 is inserted into the abutment slot 44. When the abutment block 43 moves to the bottom of the abutment slot 44, the first threaded groove 45 and the second threaded groove 46 are in the same position. Then, the fastening bolt 47 is passed through the first threaded groove 45 and screwed into the bottom of the second threaded groove 46 along the horizontal side to complete the installation process of the support back plate 42. The disassembly principle is the same.

[0031] The impact protection mechanism 5 includes a limiting cylinder 51, a limiting piston rod 52, a support spring 53, and a protective outer plate 54. Three sets of limiting cylinders 51 are evenly arranged on the outer side wall of the support back plate 42 away from the small square column 2. The limiting piston rod 52 is slidably installed inside the limiting cylinder 51, and the support spring 53 is connected between the outer side wall of the limiting piston rod 52 and the inner bottom wall of the limiting cylinder 51. The protruding end of the limiting piston rod 52 is located outside the limiting cylinder 51, and the protruding end of the limiting piston rod 52 is connected to the inner side wall of the protective outer plate 54. The protective outer plate 54 is set as a transverse "U" shape structure, and the protective outer plate 54 is slidably installed outside the support back plate 42. An elastic protective pad 55 is embedded in the outer side wall of the protective outer plate 54. The limiting cylinder 51 is filled with damping fluid, and the outer side wall of the limiting piston rod 52 located at the piston plate position has through holes evenly spaced around it for the damping fluid to flow through.

[0032] After the aforementioned support back plate 42 is installed, the installation process of the impact protection mechanism 5 will be completed simultaneously. Since the middle section of the small square post 2 is the part of the guardrail most prone to bending and damage, this application sets an impact protection mechanism 5 on the outer side of the middle of the small square post 2 to protect it. When an external force impacts the protective outer plate 54, the elastic protective pad 55 set inside the protective outer plate 54 will buffer the impact force through elastic deformation. At the same time, the protective outer plate 54 moves backward under the impact force and simultaneously drives multiple sets of limiting piston rods 52 to slide inside the limiting cylinder 51. When the limiting piston rods 52 slide inside the cylinder... During internal movement, the piston compresses and pushes the damping fluid from one side of the piston disc to the other. Due to the incompressibility of the fluid, the damping fluid generates resistance when squeezed. This resistance hinders the rapid movement of the piston, thereby slowing down its speed and simultaneously reducing the energy of the impact. At this time, the support spring 53 deforms and contracts under the squeezing action of the limited piston rod 52, and simultaneously buffers and consumes the impact force. This process completes the secondary buffering. In addition, the above-mentioned secondary buffering process achieves the effect of buffering and consuming the impact force on the outside of the device, thereby achieving the effect of isolation and protection for the guardrail.

[0033] In use, the device must first be assembled and placed in the designated location. At this point, the two sets of uprights 1 are placed on the ground according to the predetermined placement position. Here, the first crossbeam 31 and the second crossbeam 32, together with the two sets of uprights 1, form a complete frame structure. Then, the small square columns 2 are sequentially arranged and installed in the middle position between the first crossbeam 31 and the second crossbeam 32. During installation, the small square columns 2 are first pushed horizontally to the middle position of the two auxiliary positioning blocks 33 in the same group. Then, through the combined limiting action of the upper and lower sets of auxiliary positioning blocks 33, the small square columns 2 can be accurately positioned in the first crossbeam 31. The first crossbeam 31 is positioned between the second crossbeam 32. Then, the insertion post 35 is inserted vertically downward through the cylindrical insertion slot above the first crossbeam 31 and into the cylindrical slot 34. When the insertion post 35 reaches the bottom of the cylindrical slot 34, the threaded post 36 at its bottom end is screwed into the cylindrical threaded slot 37 to complete the installation of a single set of small square columns 2. The installation and disassembly of other sets of small square columns 2 are carried out in the same way. However, it should be noted that the two sets of small square columns 2 with support blocks 41 on their outer walls need to be installed at the outermost edge of the device to facilitate the installation of the support back plate 42 described below.

[0034] After the entire frame of the above-mentioned column body 1, small square column 2, first crossbeam 31 and second crossbeam 32 is assembled, the support back plate 42 needs to be adjusted to a suitable position and the abutment block 43 on its side should be inserted into the abutment slot 44. When the abutment block 43 moves to the bottom of the abutment slot 44, the first threaded groove 45 and the second threaded groove 46 are in the same position. Then, the fastening bolt 47 is passed through the first threaded groove 45 and screwed into the bottom of the second threaded groove 46 along the horizontal side to complete the installation process of the support back plate 42.

[0035] After the aforementioned support back plate 42 is installed, the installation process of the impact protection mechanism 5 will be completed simultaneously. Since the middle section of the small square post 2 is the part of the guardrail most prone to bending and damage, this application sets an impact protection mechanism 5 on the outer side of the middle of the small square post 2 to protect it. When an external force impacts the protective outer plate 54, the elastic protective pad 55 set inside the protective outer plate 54 will buffer the impact force through elastic deformation. At the same time, the protective outer plate 54 moves backward under the impact force and simultaneously drives multiple sets of limiting piston rods 52 to slide inside the limiting cylinder 51. When the limiting piston rods 52 slide inside the cylinder... During internal movement, the piston compresses and pushes the damping fluid from one side of the piston disc to the other. Due to the incompressibility of the fluid, the damping fluid generates resistance when squeezed. This resistance hinders the rapid movement of the piston, thereby slowing down its speed and simultaneously reducing the energy of the impact. At this time, the support spring 53 deforms and contracts under the squeezing action of the limited piston rod 52, and simultaneously buffers and consumes the impact force. This process completes the secondary buffering. In addition, the above-mentioned secondary buffering process achieves the effect of buffering and consuming the impact force on the outside of the device, thereby achieving the effect of isolation and protection for the guardrail.

[0036] It should be noted here that the above-mentioned column body 1 can be installed by using existing methods to secure it to the ground with ground nails. (See attached...) Figure 1 As shown, the guardrails in this application are installed in a row. The two sets of guardrails shown in the figure are only for illustrating the installation method. In actual installation, multiple sets of guardrails can be installed in sequence according to the attached drawings. All of these are existing conventional operating techniques, so they will not be described in detail here.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
