[0020] The structure of the present utility model will be described in detail below with reference to the accompanying drawings.

[0021] As Figures 1 to 4 shown, a railway guardrail convenient for installation provided by an embodiment of the present utility model includes a guardrail 1 and two mounting columns 2. The left and right sides of the guardrail 1 are movably connected to the opposite sides of the two mounting columns 2. A mounting shell 3 is fixedly connected to the top of the mounting column 2. Mounting blocks 4 adapted to cooperate with the mounting shell 3 are fixedly connected to the left and right sides of the guardrail 1. The opposite sides of the two mounting blocks 4 are in contact with the surface of the mounting shell 3. A control rotating block 5 is movably connected to the top of the mounting shell 3 through a rotating shaft. The bottom of the control rotating block 5 penetrates through the mounting shell 3 and extends into the inner cavity of the mounting shell 3. An installation device 6 is arranged inside the mounting shell 3.

[0022] Referring to Figure 4 , the installation device 6 includes two fixed clamping blocks 601. An outer shell 602 is fixedly connected to the side of the fixed clamping block 601 away from the guardrail 1. An inner shell 603 is movably connected to the inner cavity of the outer shell 602. The side of the inner shell 603 close to the inner cavity of the mounting shell 3 is fixedly connected to the inner cavity of the mounting shell 3. A spring 604 is fixedly connected to the surface of the fixed clamping block 601. The surface of the spring 604 is fixedly connected to the inner cavity of the mounting shell 3.

[0023] Adopting the above solution: By arranging the installation device 6, when the guardrail 1 moves to the opposite sides of the two mounting columns 2, the installation device 6 has a limiting effect on the position of the guardrail 1.

[0024] Referring to Figure 2 , two clamping grooves 7 adapted to cooperate with the fixed clamping blocks 601 are formed on the surface of the mounting block 4. The surface of the clamping block is in contact with the inner cavity of the clamping groove 7.

[0025] Adopting the above solution: By arranging the clamping groove 7, when the mounting shell 3 moves to the position in contact with the surface of the mounting block 4 and the control rotating block 5 is released, the force generated by the spring 604 restoring its shape will drive the fixed clamping block 601 to snap into the inner cavity of the clamping groove 7. The cooperation of the fixed clamping block 601 and the clamping groove 7 has a limiting effect on the position of the mounting block 4.

[0026] Referring to Figure 4 , a moving column 8 is fixedly connected to the top of the fixed clamping block 601. Two moving shells 9 adapted to cooperate with the moving column 8 are movably connected to the inner cavity of the mounting shell 3. The surface of the moving column 8 is in contact with the inner cavity of the moving shell 9.

[0027] Adopt the above solution: By setting the moving column 8 and the moving shell 9, when the moving shell 9 moves, it can generate a squeezing force on the moving column 8, and the moving column 8 subjected to the squeezing force can drive the fixed clamping block 601 to move.

[0028] Reference Figure 4 , a stable hole 10 is opened on the surface of the moving shell 9, and two stable clamping blocks 11 used in cooperation with the stable hole 10 are fixedly connected to the top of the inner cavity of the mounting shell 3, and the inner cavity of the stable hole 10 is movably connected to the surface of the stable clamping block 11.

[0029] Adopt the above solution: By setting the stable hole 10 and the stable clamping block 11, when the moving shell 9 moves, it will drive the stable hole 10 to move along the surface of the stable clamping block 11, and the cooperation of the stable hole 10 and the stable clamping block 11 has a limiting effect on the moving position of the moving shell 9.

[0030] Reference Figure 4 , an extrusion hole 12 is opened on the surface of the moving shell 9, and an extrusion rod 13 used in cooperation with the extrusion hole 12 is fixedly connected to the bottom of the control rotating block 5, and the surface of the extrusion rod 13 is in contact with the inner cavity of the extrusion hole 12.

[0031] Adopt the above solution: By setting the extrusion hole 12 and the extrusion rod 13, when the control rotating block 5 rotates, it will drive the extrusion rod 13 to rotate along the inner cavity of the extrusion hole 12, and the extrusion rod 13 can generate a squeezing force on the extrusion hole 12, and the extrusion hole 12 subjected to the squeezing force can drive the two moving shells 9 to move.

[0032] Reference Figure 2 and Figure 3 , plugging rods 14 are fixedly connected to both the left and right sides of the guardrail 1, plugging grooves 15 used in cooperation with the plugging rods 14 are opened at the top of the mounting column 2, and the surface of the plugging rod 14 is in contact with the inner cavity of the plugging groove 15.

[0033] Adopt the above solution: By setting the plugging rod 14 and the plugging groove 15, when the guardrail 1 moves between the two mounting columns 2, it will drive the plugging rod 14 to move into the inner cavity of the plugging groove 15, and the cooperation of the plugging rod 14 and the plugging groove 15 has a limiting effect on the moving position of the guardrail 1.

[0034] The working principle of the present utility model:

[0035] During use, when the guardrail 1 for railway needs to be installed conveniently, first the user rotates the control rotating block 5. When the control rotating block 5 rotates, it will drive the extrusion rod 13 to rotate along the inner cavity of the extrusion hole 12. The extrusion hole 12 under the extrusion force will drive the two moving shells 9 to move towards the closer side to each other. When the moving shell 9 moves, it will drive the stable hole 10 to move along the surface of the stable block 11. At the same time, the movement of the moving shell 9 will generate an extrusion force on the moving column 8. The two moving columns 8 under the extrusion force will move towards the side closer to the control rotating block 5. When the moving column 8 moves, it will drive the fixed block 601 to move towards the side closer to the control rotating block 5. When the fixed block 601 moves, it will drive the outer shell 602 to move along the surface of the inner shell 603. The force generated when the fixed block 601 moves causes the spring 604 to undergo elastic deformation. When the fixed block 601 moves into the inner cavity of the installation shell 3, the insertion rod 14 is moved into the inner cavity of the insertion slot 15, and at the same time, the guardrail 1 is driven to move between the two installation columns 2. When the guardrail 1 completely moves between the two installation columns 2, the surface of the installation block 4 will contact the surface of the installation shell 3. Then release the control rotating block 5. The restoring force generated when the spring 604 resumes its shape will drive the fixed block 601 to snap into the inner cavity of the card slot 7. The combined use of the fixed block 601 and the card slot 7 has a limiting effect on the position of the guardrail 1. The combined use of the fixed block 601 and the fixed slot has a limiting effect on the position of the guardrail 1. At this time, the guardrail 1 for railway is conveniently installed.

[0036] In summary: For this railway guardrail that is easy to install, by setting up the combined use of the installation device 6, the fixed block 601, the outer shell 602, the inner shell 603, the spring 604 and the card slot 7, it solves the problem that when installing the existing railway guardrail, several installation columns need to be set on the ground, and then several connecting pieces are set on the installation columns. The guardrail will be fixed to the connecting pieces by bolts. The bolts may become loose due to improper installation or long use time. And once the bolts start to corrode and become loose, the work of maintenance and replacement will become more difficult and complex. However, there are no components for convenient installation in the existing railway guardrails.
