Specific implementation
[0034] The utility model will be explained further in detail in combination with the drawings and specific implementation.
[0035] For the purpose of simplicity and concision of the drawings, only the parts related to the utility model are shown in the drawings, which do not represent the actual structure of the product. In addition, for the purpose of simplicity and conciseness of the drawings, parts having the same structure or function are only shown in one of them or only one of them is marked. In this document, "one" means not only "only one", but also "more than one", and "several" includes "two" and "more than two".
[0036] In this document, it should be noted that unless otherwise specified and limited, the terms "mounting", "connection" and "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or internal communication of two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific situation.
[0037] In addition, in the description of this application, the terms "first", "second" and the like are only used for differentiation and description, and cannot be understood as indicating or implying relative importance.
[0038] As shown in Figures 1-11 A steel structure crash barrier, comprising a support assembly composed of a plurality of supports 1 arranged at intervals, further comprising: a sliding seat 2, having two, the two sliding seats 2 are symmetrically arranged on one side of the support assembly, the sliding seat 2 has a sliding groove 201, the sliding groove 201 is in the shape of "convex", and the sliding groove 201 is divided into upper and lower groove structures, the wider groove structure is a guide groove 202, and the narrower groove structure is an avoidance groove 203, the sliding seat 2 has a plurality of through holes 204 arranged at intervals, the through holes 204 are vertically arranged and communicate with the avoidance groove 203; a support rod 3, having a plurality of, the support rod 3 has a connecting head 301 on the upper and lower sides, the connecting heads 301 on the upper and lower sides are respectively slidingly arranged in the guide grooves 202 on the upper and lower sides, the connecting head 301 has an insertion hole 3011 opposite to the position of the through hole 204; a latch 4, having a plurality of, the latch 4 is inserted into the insertion hole 3011 after passing through the through hole 204, used for positioning the connecting head 301, when the support rod 3 is hit, the latch 4 is separated from the positioning of the connecting head 301. The latch 4 is made of steel or plastic.
[0039] In use, the support rod 3 is installed between the two sliding seats 2, and can be positioned by the latch 4 to avoid random sliding. There is also friction between the connecting head 301 and the guide groove 202, which facilitates the consumption of part of the kinetic energy when the support rod 3 slides with the vehicle, and the gradual accumulation of multiple support rods 3 weakens the impact speed and energy.
[0040] The pin 4 can be made of plastic material and can be easily broken or fragmented, or can be made of steel wire and can be broken or bent, thereby eliminating the positioning of the support rod 3. For example, the pin 4 is inserted into the insertion hole 3011 of the connecting head 301 from the upper through hole 204. When the support rod 3 is impacted, the lower part of the pin 4 can be separated from the insertion hole 3011 and bent and accommodated in the avoiding groove 203. At this time, the support rod 3 can slide. Similarly, the upper part of the pin 4 can be separated from the through hole 204 to cancel the positioning. The upper and lower slides 2 can position the connecting heads 301 at the upper and lower ends of the support rod 3 through the pin 4, so that the force is more balanced. The connecting head 301 can be a cylindrical structure or a square structure.
[0041] The sliding groove 201 is in the shape of a "convex" character. The slide 2 can have a blocking edge to prevent the connecting head 301 from being thrown out, so that the support rod 3 is more easily slid along the guide groove 202. Here, the strength is achieved by the sliding of the support rod 3 in the event of a vehicle impact. When a vehicle approaches a guardrail in a sudden accident, it is usually side-impact and still travels in the driving direction.
[0042] Further, it further comprises a plurality of buffer tiles 5, which are vertically arranged on one side of the support rod 3 and have a gap between the buffer tile 5 and the support rod 3. The slide 2, the support rod 3 and the buffer tile 5 are all made of steel material.
[0043] In use, the buffer tile 5 is in contact with the support rod 3 and has a gap between the support rod 3 and the vehicle. After impact, it can play a deformation buffering role and reduce the impact hazard.
[0044] Further, the support rod 3 has a plurality of mounting holes 302 arranged in the vertical direction and a plurality of insertion assemblies arranged on the buffer tile 5. The insertion assembly comprises two oppositely arranged insertion plates 6. The insertion plate 6 comprises an insertion part 601 and an outer convex part 602 arranged obliquely opposite to the insertion part 601. The outer convex part 602 is fixedly arranged on one side of the support rod 3. The insertion part 601 passes through the mounting hole 302 and is fixed on the support rod 3 by bending the part of the insertion part 601 protruding from the mounting hole 302 to the surface of the support rod 3. The buffer tile 5 is arc-shaped and the support rod 3 is located inside the buffer tile 5.
[0045] In use, the buffer tile 5 is arc-shaped and located outside the support rod 3, and the outer arc surface of the buffer tile 5 is in abutment with the vehicle, after impact, the plug-in assembly is deformed to play a buffering role. The buffer tile 5 is installed on the support rod 3 through the plug-in assembly, the plug-in assembly is generally in the shape of "Y", the part of the "Y" shape extending outward (i.e. the outer convex part 602 arranged obliquely) is located between the support rod 3 and the inner wall of the buffer tile 5, and is in abutment with one side of the support rod 3 to realize unilateral positioning, and the combined part, i.e. the plug-in part 601, is bent to both sides after passing through the mounting hole 302, including the support rod 3, and is positioned on the other side of the support rod 3, thereby fixing the buffer tile 5 on the support rod 3. The fixed connection of the plug-in assembly and the support rod 3 can be strengthened by means of spot welding of a small area.
[0046] The buffer tile 5 is arc-shaped and located outside the support rod 3, and when the support rod 3 slides, two adjacent buffer tiles 5 will be stacked and deformed by extrusion to realize buffering.
[0047] Further, the bracket 1 has a recess 101 at the upper part, and further comprises a warning light 7 which is arranged in the recess 101.
[0048] In use, the bracket 1 is fixed on the road, and the recess 101 at the upper part of the bracket 1 can be arranged in the vertical direction, and the warning light 7 is conveniently installed through the structure of the recess 101, and the warning light 7 can be an active light or a reflector lamp.
