DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] The utility model provides Figure 1-4The illustrated embodiment of a corrosion-resistant and durable metal guardrail comprises a fixed base plate 1, a riser column 2 is symmetrically fixedly connected to the top of the fixed base plate 1, a plurality of cross bars 5 are arranged on opposite sides of the riser column 2, threaded rods 6 are fixedly connected to both ends of the cross bars 5, one end of the threaded rod 6 away from the cross bars 5 is inserted and connected to the inner cavity of the riser column 2, a sleeve 7 is sleeved at one end of the threaded rod 6 and located in the inner cavity of the riser column 2, a rotating member for fixing the cross bars 5 is arranged on the outside of the threaded rod 6 and located inside the sleeve 7, the rotating member comprises a moving ring 9, one end of the threaded rod 6 is threadedly inserted and connected to the middle of the moving ring 9;

[0019] It should be noted that movable grooves 201 are symmetrically provided on opposite sides of the riser column 2. The movable grooves 201 are used for the threaded rod 6 to move up and down in the inner cavity of the riser column 2. The inner wall at the bottom thereof is inclined outward at 10 degrees toward the inner cavity of the riser column 2 to prevent rainwater from entering the inner cavity of the riser column 2. A decorative block 3 for blocking the top of the riser column 2 is fixedly connected to the top of the riser column 2. The decorative block 3 is spherical in shape to prevent the top inner cavity of the riser column 2 from being exposed to the outside world, and also serves to beautify the fence. The riser column 2 and the crossbar 5 are both made of stainless steel, which has excellent corrosion resistance and durability. The diameter of the crossbar 5 is one-third of the diameter of the riser column 2. Both ends of the crossbar 5 and the threaded rod 6 are fixed by welding. A thread for meshing with the threaded rod 6 is provided in the middle of the movable ring 9. The threads of the two threaded rods 6 are in opposite directions to facilitate the tightening of the crossbar 5. The movable ring 9 is square, and the inner cavity of the sleeve 7 is square.

[0020] Specifically, a pressure ring 13 is sleeved on the outer side of one end of the threaded rod 6 and located on the side of the moving ring 9 close to the cross bar 5. The pressure ring 13 is arranged inside the sleeve 7. The pressure ring 13 is away from the moving ring 9 and connecting rods 12 are symmetrically arranged on both sides of the threaded rod 6. The end of the connecting rod 12 away from the pressure ring 13 is fixedly connected to the compression spring 11. The end of the compression spring 11 away from the pressure ring 13 is fixedly connected to the inner wall of one end of the sleeve 7 close to the cross bar 5.

[0021] It should be noted that the middle aperture of the pressure ring 13 is larger than the diameter of the threaded rod 6, and lubricating grease is applied at the insertion point, which can reduce the friction of the threads on the outer side of the threaded rod 6 on the pressure ring 13 and reduce the resistance of the pressure ring 13 to move. The connecting rod 12 and the sides of the pressure ring 13 are fixed by welding. The diameter of one end of the connecting rod 12 fixed to the compression spring 11 is larger than the diameter of the compression spring 11 and larger than the diameter of the other end of the connecting rod 12. The connecting rod 12 and the compression spring 11 are fixed by welding. The inner wall of one end of the sleeve 7 close to the cross bar 5 and located in the middle of one end of the compression spring 11 is fixedly connected to the limiting column 14. The limiting column 14 is used to prevent the compression spring 11 from tilting when it is deformed. The function of the compression spring 11 is to relieve the impact of the moving ring 9 and the sleeve 7.

[0022] Specifically, a friction block 8 for increasing the friction force of the side of the sleeve 7 is fixedly connected to the side of the sleeve 7 near one end of the crossbar 5 and located in the inner cavity of the riser column 2, and an arc block 10 is inserted and connected to the outer side of the end of the sleeve 7 away from the crossbar 5 and located in the inner cavity of the riser column 2. The side of the arc block 10 is fixedly connected to the side of the friction block 8, so that the spacing of the crossbars 5 can be adjusted according to the actual needs of the user, avoiding the problem that the crossbars 5 are fixed by welding and the spacing cannot be adjusted;

[0023] It should be noted that the friction block 8 is made of rubber material and is bonded to the side of the sleeve 7 by glue. When the threaded rod 6 drives the sleeve 7 to move, the compression spring 11 buffers the movement of the sleeve 7. At the same time, when the sleeve 7 moves, the friction block 8 is squeezed to be squeezed against the inner wall of the riser column 2, so as to fix the position of the sleeve 7. A limiting ring 601 is provided at one end of the threaded rod 6 and located in the inner cavity of the sleeve 7. The limiting ring 601 is used to prevent the moving ring 9 from being separated from the threaded rod 6.

[0024] During actual use, a plurality of fixing rods 4 are fixedly connected to one side of the fixed base plate 1, and a plurality of fixing grooves 101 are opened on the other side of the fixed base plate 1. The user fixes the fixing rods 4 through the fixing grooves 101, and the connection of the fixed base plate 1 can be fixed by welding or concrete. During the use of the cross bar 5, the user drives the threaded rod 6 to rotate by rotating the cross bar 5, and moves the rotating threaded rod 6 in the fixing groove 101. After the cross bar 5 moves to the desired position, the cross bar 5 is rotated in the opposite direction, and the threaded rod 6 drives the moving ring 9 inside the sleeve 7 to move toward the position of the cross bar 5, thereby realizing that the moving ring 9 drives the sleeve 7 to move toward the direction of the cross bar 5, so that the friction block 8 on the side of the sleeve 7 is deformed and squeezes the inner side of the riser column 2, and the cross bar 5 is fixed by friction.

[0025] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
