[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] Figure 1 It is a schematic diagram of the overall structure of the utility model, and combined with Figure 2-Figure 5 As shown, the highway guardrail includes two support members, which are arranged vertically and in parallel. Upper mounting blocks 3 are fixed to the upper ends of the outer walls of the two support members, and lower mounting blocks 4 are fixed to the lower ends of the outer walls of the two support members. An upper cross bar 5 is detachably provided between the two upper mounting blocks 3 at the upper ends, and a lower cross bar 6 is detachably provided between the two lower mounting blocks 4 at the lower ends. T-slots 16 are provided on the upper mounting blocks 3 and the lower mounting blocks 4. Both ends of the upper cross bar 5 and the lower cross bar 6 are connected to T-shaped plug blocks 14, and the T-shaped plug blocks 14 are inserted and matched with the T-slots 16.

[0029] The support member includes a bottom pier 1 and a support rod 2 . A slot 12 is provided at the top of the bottom pier 1 , and the bottom end of the support rod 2 is inserted and matched in the slot 12 .

[0030] Second, see Figure 3 and Figure 4 As shown, a plurality of through grooves 13 are equidistantly formed on the upper horizontal bar 5 , a plurality of shallow grooves 15 are equidistantly formed on the upper end surface of the lower horizontal bar 6 , vertical partition bars 7 are inserted into the through grooves 13 , and the bottom ends of the vertical partition bars 7 are inserted and matched with the shallow grooves 15 .

[0031] Through the above technical solution:

[0032] When assembling for use, the bottom pier 1 and the support rod 2 can be assembled together to form a support member, and then the upper horizontal bar 5 and the lower horizontal bar 6 can be installed. After installing the upper horizontal bar 5 and the lower horizontal bar 6, the T-shaped plug 14 can be inserted into the T-shaped slot 16, and then the vertical partition bars 7 can be installed one by one, so that the vertical partition bars 7 pass through the through slot 13 on the upper horizontal bar 5 vertically downward, and then the bottom end of the vertical partition bar 7 is embedded in the shallow groove 15. The assembly is convenient. After a vertical partition bar 7 is damaged, it can be quickly disassembled and replaced without using tools to disassemble and install screws.

[0033] In addition, see Figure 6 As shown, a groove 17 is opened at the upper end of the side wall of the vertical partition bar 7, and a spring 18 is connected inside the groove 17. The free end of the spring 18 is connected to a limit block 19. The upper and lower surfaces of the limit block 19 are provided with inclined surfaces. When the spring 18 is in a natural state, the limit block 19 at least partially protrudes out of the groove 17.

[0034] Specifically, when the vertical partition bar 7 is inserted downward for installation, when the limit block 19 reaches the upper end of the upper horizontal bar 5, the limit block 19 is squeezed into the groove 17. After the limit block 19 passes through the through groove 13, under the elastic action of the spring 18, the limit block 19 at least partially protrudes out of the groove 17. The limit block 19 can be used to block the upward movement of the vertical partition bar 7 from the bottom end, and will not separate from the upper horizontal bar 5 without being subjected to a certain external force.

[0035] Secondly, according to the required length of the highway, further assembly and extension can be carried out on the basis of the guardrail composed of two supporting members.

[0036] In addition, see Figure 7 As shown, a groove 22 is formed at the top of the support rod 2, an embedding rod 21 is inserted into the embedding groove 22, a baffle 8 is fixed to the top of the embedding rod 21, and a reflective ball 9 is installed on the upper end surface of the baffle 8.

[0037] As mentioned above, the reflective ball 9 can play a reflective role, which can remind drivers to avoid accidents at night and reduce the occurrence of collisions. When installing the reflective ball 9, the embedded rod 21 can be inserted into the embedded groove 22, and installation and removal are quick and convenient.

[0038] Also, see Figure 1 and Figure 6 As shown, a reminder plate 11 is detachably provided at the top end of the vertical partition bar 7.

[0039] The bottom end of the prompt plate 11 is connected with a threaded rod 10 , the top end of the vertical partition bar 7 is provided with a threaded groove 20 , and the threaded rod 10 is screwed into the threaded groove 20 .

[0040] A cardboard with reminder words can be pasted on the reminder board 11 to remind people to avoid or guide.

[0041] When installing the prompt plate 11 , it is only necessary to screw the threaded rod 10 into the threaded groove 20 , so that installation and removal are convenient and quick.

[0042] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
