Description

Technical Field

[0001] The utility model relates to the technical field of road protection, and specifically, to a municipal road guardrail. Background Art

[0002] A guardrail is a railing set up to avoid danger or block passage. Generally, guardrails are installed in the center of municipal roads, which mainly divide the municipal roads into two oncoming lanes and are widely used in municipal roads.

[0003] For example, a municipal road guardrail disclosed in the patent with the patent number CN220619898U includes two U-shaped frame plates and two horizontal rails. Fixed plates are fixedly installed on the inner sides of the U-shaped frame plates. Installation grooves are formed on the upper and lower surfaces of the fixed plates. Return springs are fixedly installed inside the installation grooves. One end of each return spring is fixedly connected to a limiting member that penetrates through a plug-in block. Although the horizontal rails and the U-shaped frame plates in this municipal road guardrail are connected by plug-in blocks and plug-in holes, and the elastic force of the return springs is used to insert both ends of the limiting members connected thereto into the interior of the plug-in blocks, so that the horizontal rails and the U-shaped frame plates are fixedly connected. However, there are some deficiencies in this road guardrail. In actual use, when this municipal road guardrail is installed on a turning road, the rotational connection between the guardrails cannot be achieved, resulting in the inapplicability of this type of guardrail on turning roads, so it needs to be improved. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a municipal road guardrail to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] A municipal road guardrail includes bottom rods arranged oppositely. Lower cylinders are provided at the upper ends of the bottom rods. Vertical rods are provided on the lower cylinders. Upper cylinders are provided on the vertical rods. Top rods are provided on the upper cylinders. Rod caps are provided on the top rods. Upper fixing blocks are provided on the side walls of the vertical rods and the top rods. Rotatable upper clamps are provided on the surfaces of the upper cylinders. Upper rotating blocks are provided on the upper clamps. Upper crossbars are provided between the upper fixing blocks and the upper rotating blocks. Lower fixing blocks are provided on the side walls of the vertical rods and the bottom rods. Rotatable lower clamps are provided on the surfaces of the lower cylinders. Lower rotating blocks are provided on the lower clamps. Lower crossbars are provided between the lower fixing blocks and the lower rotating blocks. A plurality of vertical rods are evenly distributed between the upper crossbars and the lower crossbars.

[0007] Furthermore, upper placing grooves for the two ends of the upper crossbar to extend into are respectively formed on the upper fixing blocks and the upper rotating blocks. Lower placing grooves for the two ends of the lower crossbar to extend into are respectively formed on the lower fixing blocks and the lower rotating blocks.

[0008] Further, a plurality of slots are provided on the upper cross bar corresponding to the vertical bars, and a plurality of limiting slots are provided on the lower cross bar corresponding to the vertical bars. The bottom end of the vertical bar can be inserted into the limiting slot through the slot. A pressing plate is provided on the upper cross bar for plugging the top end of the vertical bar. Fixing components for fixing the pressing plate are symmetrically provided on the two side walls of the upper fixing block and the upper rotating block respectively.

[0009] Further, both ends of the pressing plate extend into the corresponding upper placement slots respectively, and insertion holes are formed on the side walls located in the upper placement slots. The fixing component includes cylinders provided on the side walls of the upper fixing block and the upper rotating block. An installation cavity is formed in the cylinder. A plug rod is provided in the installation cavity and can penetrate through the bottom wall of the installation cavity and be inserted into the insertion hole. A pushing block is provided at the end of the plug rod close to the bottom wall of the installation cavity. A plug cap is provided at the opening of the installation cavity. A spring for pushing the plug rod to be inserted into the insertion hole is sleeved on the plug rod between the plug cap and the pushing block.

[0010] Further, one end of the plug rod extends out of the plug cap, and a pulling block for pulling the plug rod out of the insertion hole is provided at the end of the plug rod extending out of the plug cap.

[0011] Further, a base for fixing to the road is provided at the lower end of the bottom rod.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. For this municipal road guardrail, when encountering a turning road, a set of guardrails can be rotated according to the turning direction of the road. Through the rotation of the upper cross bar and the lower cross bar, the upper clamp and the lower clamp respectively connected to the upper rotating block and the lower rotating block can be driven to rotate synchronously around the upper cylinder and the lower cylinder, thereby driving the rotation of a set of guardrails. Then, according to the length of the turning road, rotating multiple sets of guardrails can complete the installation of the guardrails on the turning road, preferably solving the problem that when installing guardrails on a turning road, the rotation between the guardrails cannot be realized and it is not applicable on the turning road.

[0014] 2. For this municipal road guardrail, through the settings of the upper placement slots and the lower placement slots, when assembling the guardrails, the two ends of the lower cross bar can be first placed into the corresponding lower placement slots, and then the two ends of the upper cross bar can be placed into the corresponding upper placement slots, thus completing the preliminary installation of the upper cross beam and the lower cross beam, and the installation is relatively simple.

[0015] 3. The municipal road guardrail is provided with slots, limit slots, pressure plates and fixing components, so that when the vertical rod is installed, the bottom end of the vertical rod is inserted into the limit slot through the slot, so that the bottom end of the vertical rod is located in the limit slot and the top end is located in the slot, and the installation of the vertical rod between the upper cross bar and the lower cross bar is completed. After the vertical rod is installed, the pressure plate is placed above the cross bar, and the two ends of the pressure plate are extended into the corresponding upper placement slots, and then the two ends of the pressure plate are fixed by the fixing component, so that the pressure plate can block the slot. Since the pressure plate and the limit slot limit the vertical rod, the vertical plate cannot be detached from the slot and the limit slot, so that the vertical rod is preferably fixedly installed between the upper cross bar and the lower cross bar.

[0023] The following is combined with Figures 1 - 5 This embodiment is described in further detail.

[0024] See alsoFigures 1 - 5 , a kind of municipal road guardrail in this embodiment includes bottom bars 1 arranged oppositely. Lower cylinders 2 are provided at the upper ends of the bottom bars 1. Vertical bars 3 are provided on the lower cylinders 2. Upper cylinders 4 are provided on the vertical bars 3. Top bars 5 are provided on the upper cylinders 4. Rod caps 6 are provided on the top bars 5. Upper fixing blocks 7 are provided between the side walls of the vertical bars 3 and the top bars 5. Rotatable upper clamps are provided on the surfaces of the upper cylinders 4. Upper rotating blocks 9 are provided on the upper clamps. Upper cross bars 10 are provided between the upper fixing blocks 7 and the corresponding upper rotating blocks 9. Lower fixing blocks 11 are provided between the side walls of the vertical bars 3 and the bottom bars 1. Rotatable lower clamps are provided on the surfaces of the lower cylinders 2. Lower cross bars 14 are provided between the lower fixing blocks 11 and the corresponding lower rotating blocks 13. A plurality of vertical bars 15 are evenly arranged between the upper cross bars 10 and the lower cross bars 14. A base 16 for fixing to the road is provided at the lower end of the bottom bar 1.

[0025] In this embodiment, through the settings of the bottom bar 1, the lower cylinder 2, the vertical bar 3, the upper cylinder 4 and the top bar 5, a support column for supporting the guardrail is preferably formed. Among them, through the setting of the base 16, the formed support column is preferably fixed on the road, improving the stability of the guardrail;

[0026] Among them, through the settings of the upper fixing block 7, the upper clamp, the upper rotating block 9, the upper cross bar 10, the lower fixing block 11, the lower clamp, the lower rotating block 13, the lower cross bar 14 and the vertical bar 15, the side wall of the upper fixing block 7 is fixed between the vertical bar 3 and the top bar 5. The upper clamp is rotatably connected to the upper cylinder 4. The upper rotating block 9 is fixedly connected to the upper clamp, so that the upper cross bar 10 can be lapped and installed between the upper rotating block 9 and the upper fixing block 7. The side wall of the lower fixing block 11 is fixed between the vertical bar 3 and the bottom bar 1. The lower clamp is rotatably connected to the lower cylinder 2. The lower rotating block 13 is fixedly connected to the lower clamp, so that the lower cross bar 14 can be lapped and installed between the lower rotating block 13 and the lower fixing block 11. Thus, the vertical bar 15 is connected between the upper cross bar 10 and the lower cross bar 14. Thus, a guardrail is preferably assembled. Due to the rotational settings of the upper clamp and the lower clamp, the successively spliced guardrail can turn, thereby solving the problem that the existing guardrail cannot be rotatably connected and thus cannot be installed on a turning road;

[0027] Among them, the setting of the rod cap 6 is used to protect the top bar 5 and for decoration;

[0028] In actual use of this embodiment, the upper clamp includes two mutually cooperating first arc-shaped clamps 8. The upper rotating block 9 is fixedly installed on one of the two first arc-shaped clamps 8. The rotational connection of the upper clamp outside the upper cylinder 4 is realized by splicing the two first arc-shaped clamps 8;

[0029] The lower clamp includes two mutually cooperating second arc-shaped clamps 12, and the lower rotating block 13 is fixedly installed on one of the two second arc-shaped clamps 12. The lower clamp is rotatably connected to the lower cylinder 2 by splicing the two second arc-shaped clamps 12.

[0030] It should be noted that in this embodiment, there are corresponding spacings between the side walls of the upper fixing block 7 and the lower fixing block 11 and the surfaces of the upper cylinder 4 and the lower cylinder 2, which do not affect the rotational connection of the first arc-shaped clamp 8 and the second arc-shaped clamp 12 on the upper cylinder 4 and the lower cylinder 2.

[0031] Please refer to Figures 1 - 5 In this embodiment, upper placement grooves 100 for the two ends of the upper crossbar 10 to extend into are respectively formed in the upper fixing block 7 and the upper rotating block 9, and lower placement grooves 101 for the two ends of the lower crossbar 14 to extend into are respectively formed in the lower fixing block 11 and the lower rotating block 13.

[0032] In this embodiment, through the settings of the upper placement grooves 100 and the lower placement grooves 101, when assembling the guardrail, the two ends of the lower crossbar 14 can be respectively placed into the corresponding lower placement grooves 101 first, and then the two ends of the upper crossbar 10 are placed into the corresponding upper placement grooves 100, and the preliminary installation of the upper crossbar 10 and the lower crossbar 14 can be completed, and the installation is relatively simple.

[0033] Please refer to Figures 1 - 5 In this embodiment, a plurality of slots 102 corresponding to the vertical rods 15 are provided on the upper crossbar 10, a plurality of limiting grooves 103 corresponding to the vertical rods 15 are provided on the lower crossbar 14, the bottom end of the vertical rod 15 can be inserted into the limiting grooves 103 from the slots 102, a pressing plate 104 for blocking the top end of the vertical rod 15 is provided on the upper crossbar 10, and fixing components for fixing the pressing plate 104 are symmetrically provided on the two side walls of the upper fixing block 7 and the upper rotating block 9 respectively.

[0034] In this embodiment, through the settings of the slots 102, the limiting grooves 103, the pressing plate 104 and the fixing components, when installing the vertical rod 15, the bottom end of the vertical rod 15 is inserted into the limiting grooves 103 through the slots 102, so that the bottom end of the vertical rod 15 is located in the limiting grooves 103 and the top end is located in the slots 102, and the installation of the vertical rod 15 between the upper crossbar 10 and the lower crossbar 14 can be completed. After the vertical rod 15 is installed, the pressing plate 104 is placed above the crossbar, and at the same time, the two ends of the pressing plate 104 extend into the corresponding upper placement grooves 100, and then the two ends of the pressing plate 104 are fixed by the fixing components, so that the pressing plate 104 can block the slots 102. Since the pressing plate 104 and the limiting grooves 103 limit the vertical rod 15, the vertical rod 15 cannot be separated from the slots 102 and the limiting grooves 103, and preferably the vertical rod 15 is fixedly installed between the upper crossbar 10 and the lower crossbar 14.

[0035] In this embodiment, the slot 102 runs through the upper crossbar 10, and the limiting slot 103 does not run through the lower crossbar 14.

[0036] Please refer to Figures 1 - 5 , in this embodiment, both ends of the pressing plate 104 extend into the corresponding upper placement slots 100 respectively, and jack holes 200 are formed on the side walls in the upper placement slots 100. The fixing assembly includes cylinders 201 provided on the side walls of the upper fixing block 7 and the upper rotating block 9. An installation cavity 202 is formed in the cylinder 201. A plug rod 203 that penetrates the bottom wall of the installation cavity 202 and can be inserted into the jack hole 200 is provided in the installation cavity 202. A pushing block 204 is provided at the end of the plug rod 203 close to the bottom wall of the installation cavity 202. A plug cap 205 is provided at the opening of the installation cavity 202. A spring 206 sleeved on the plug rod 203 for pushing the plug rod 203 to insert into the jack hole 200 is provided between the plug cap 205 and the pushing block 204.

[0037] In this embodiment, through the settings of the jack hole 200, the cylinder 201, the installation cavity 202, the plug rod 203, the pushing block 204, the plug cap 205 and the spring 206, the cylinder 201 is fixedly connected to the upper fixing block 7 and the upper rotating block 9 respectively, the pushing block 204 is fixedly connected to the plug rod 203, and the plug cap 205 is threadedly connected to the installation cavity 202. When fixing the pressing plate 104, the spring 206 pushes the pushing block 204, and the pushing block 204 pushes the plug rod 203, so as to drive the plug rod 203 to insert into the jack hole 200 on the pressing plate 104, making the pressing plate 104 fixed and unable to move. At the same time, since the pressing plate 104 is fixed, the upper crossbar 10 cannot be separated from the upper placement slot 100, and further the lower crossbar 14 cannot be separated from the lower placement slot 101, and the vertical rod 15 is also fixed between the upper crossbar 10 and the lower crossbar 14, making the upper crossbar 10, the lower crossbar 14 and the vertical rod 15 form a whole, preferably realizing the splicing and fixing of the guardrail.

[0038] In this embodiment, holes for the plug rod 203 to extend into the upper placement slot 100 and communicate with the jack hole 200 are formed on the side walls of the upper fixing block 7 and the upper rotating block 9.

[0039] Please refer to Figures 1 - 5 , in this embodiment, one end of the plug rod 203 extends out of the plug cap 205, and a pulling block 207 for pulling the plug rod 203 out of the jack hole 200 is provided at the end of the plug rod 203 extending out of the plug cap 205.

[0040] In this embodiment, when installing the guardrail, first insert the bottom bar 1 into the base 16, and then according to the length of the upper cross bar 10, move the two adjacent bases 16 to a suitable distance. After the distance of the bases 16 is adjusted, first put the two ends of the lower cross bar 14 into the lower placement groove 101, then pull the pull block 207, so that the insertion rod 203 drives the push block 204 to compress the spring 206, so that the insertion rod 203 slides from the upper installation groove into the installation cavity 202, and then the upper cross bar 10 is placed in the upper placement groove 100 to release Open, and then insert the bottom end of the vertical rod 15 into the limit groove 103 through the slot 102, pull the pull block 207 again to disengage the insertion rod 203 from the upper mounting groove, put the two ends of the pressure plate 104 into the upper placement groove 100 and press them on the upper cross bar 10, release the pull block 207, and the spring 206 pushes the insertion rod 203 to be inserted into the socket 200 in the pressure plate 104 to fix the pressure plate 104. After the pressure plate 104 is fixed, the installation of one set of guardrails is completed, and the above steps can be repeated for the connection of multiple sets of guardrails.

[0041] In this embodiment, the installation of fixed components makes the disassembly and assembly of the guardrail easier. At the same time, the upper cross bar 10, the lower cross bar 14, the vertical bar 15, and the pressure plate 104 can be quickly disassembled and assembled into independent components, which is convenient for construction workers to carry, transport and assemble the guardrail.

[0042] See also Figures 1 - 5 In this embodiment, matching mounting portions are provided between corresponding ends of the first arc-shaped clamp 8 and between corresponding ends of the second arc-shaped clamp 12 , and the mounting portions are connected by bolts 300 and nuts 301 .

[0043] In this embodiment, by setting the bolt 300 and the nut 301, the first arc clamp 8 and the second arc clamp 12 can be better fixed on the upper cylinder 4 and the lower cylinder 2. When installing the guardrail on a curved road, the bolt 300 and the nut 301 can be loosened, and then by rotating a group of guardrails, the first arc clamp 8 and the second arc clamp 12 are driven to rotate on the upper cylinder 4 and the lower cylinder 2, which can drive the rotation of the group of guardrails to complete the installation of the guardrail on the curved road. After the turning arc is adjusted, the bolt 300 and the nut 301 are tightened to hold the first arc clamp 8 and the second arc clamp 12 on the upper cylinder 4 and the lower cylinder 2 to prevent the guardrails from rotating again. When the guardrail is installed on a straight road, the bolt 300 and the nut 301 also need to be tightened to prevent the guardrails from rotating.

[0044] Working principle: When the municipal road guardrail is in use and being installed, first insert the bottom rod 1 into the base 16. Then, according to the length of the upper crossbar 10, move two adjacent bases 16 to an appropriate distance. After the distance between the bases 16 is adjusted, first place the two ends of the lower crossbar 14 into the lower placement groove 101. Then, pull the pulling block 207, so that the inserting rod 203 drives the pushing block 204 to compress the spring 206, making the inserting rod 203 slide from the upper installation groove into the installation cavity 202. Then, place the upper crossbar 10 into the upper placement groove 100 and release it. After inserting the bottom end of the vertical rod 15 into the limiting groove 103 through the insertion slot 102, pull the pulling block 207 again to make the inserting rod 203 disengage from the upper installation groove. After placing the two ends of the pressing plate 104 into the upper placement groove 100 and pressing them above the upper crossbar 10, release the pulling block 207, and the spring 206 pushes the inserting rod 203 into the jack 200 in the pressing plate 104 to fix the pressing plate 104. After the pressing plate 104 is fixed, the installation of a set of guardrails is completed. Repeat the above steps for the connection of multiple sets of guardrails.

[0045] In summary, the above are only the preferred embodiments of the present invention. All equivalent changes and modifications made according to the scope of the patent application of the present invention shall fall within the scope covered by the patent of the present invention.
