DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1-Figure 5As shown, a road bridge guardrail comprises a fixed column 1; a guardrail frame 2 is arranged on both sides of the fixed column 1, and a connecting component is arranged between the guardrail frame 2 and the fixed column 1;

[0025] The connection assembly includes a connection block 31, which is fixedly connected to the positions of both sides of the fence 2 near the upper and lower ends, and the connection block 31 is inserted into the inside of the connection groove 32, and the connection groove 32 is opened at the positions of both sides of the fixed column 1 near the upper and lower ends. A fixing groove 35 is opened at one end of the connection block 31, and the fixing groove 35 is engaged with a fixing block 36. The fixing block 36 is sleeved inside the movable cavity 37, and the movable cavity 37 is opened at one end of the inner wall of the connection groove 32, and a spring 38 is arranged inside the movable cavity 37;

[0026] During operation, when the fixed column 1 and the fence 2 are to be assembled, first align the connecting block 31 fixedly connected on the fence 2 with the connecting groove 32, and then insert the connecting block 31 into the connecting groove 32. When the connecting block 31 is inserted into the connecting groove 32, the connecting block 31 squeezes the inclined surface on the fixed block 36, so that the fixed block 36 moves toward the inside of the movable cavity 37 under the action of the squeezing force, and squeezes the spring 38, so that the spring 38 is elastically deformed. When the connecting block 31 is fully inserted into the connecting groove 32, the squeezing force of the connecting block 31 on the fixed block 36 disappears. At this time, the fixed block 36 returns to its original position under the action of its own restoring force and is inserted into the inside of the fixed groove 35 and engages with the fixed groove 35, which limits the connecting block 31 and makes the fixed column 1 and the fence 2 connected. At this time, the assembly between the fixed column 1 and the fence 2 is completed.

[0027] Furthermore, a clamping block 33 is fixedly connected to one end of the inner wall of the connecting groove 32 away from the active cavity 37, and the clamping block 33 is engaged with the clamping groove 34, and the clamping block 33 is made of rubber. The clamping groove 34 is provided at one end of the connecting block 31 away from the fixed groove 35;

[0028] During operation, when the connecting block 31 is inserted into the connecting groove 32, the connecting block 31 simultaneously squeezes the card block 33, so that the card block 33 made of rubber material is squeezed, and the card block 33 is elastically deformed under the action of the squeezing force. When the connecting block 31 is completely inserted into the connecting groove 32, the squeezing force of the connecting block 31 on the card block 33 disappears. At this time, the card block 33 returns to its original state under the action of its own restoring force and engages with the card groove 34, thereby assisting in fixing the connecting block 31 and making the connection between the fixed column 1 and the fence 2 more stable.

[0029] Furthermore, one end of the spring 38 close to the fixed block 36 is fixedly connected to the fixed block 36, and one end of the spring 38 away from the fixed block 36 is fixedly connected to the inner wall of the movable cavity 37; a pull plate 39 is fixedly connected to one side of the fixed block 36 close to the fence 2, and the pull plate 39 passes through the fixed column 1 and extends to the outside of the fixed column 1;

[0030] During operation, when it is necessary to release the connection between the fence 2 and the fixed column 1 and to separate the fixed column 1 and the fence 2, first pull the pull plate 39 to drive the fixedly connected fixed block 36 to move toward the inside of the movable cavity 37, so that the fixed block 36 is released from the engagement with the fixed groove 35, and then the limit on the connecting block 31 is released. At this time, pull the fence 2 away from the fixed column 1, so that the connecting block 31 is disengaged from the inside of the connecting groove 32, and the fence 2 and the fixed column 1 can be completely separated.

[0031] Furthermore, a slide groove 41 is provided on a side of the fixed block 36 away from the pull plate 39, and a slider 40 is slidably connected inside the slide groove 41, and the slider 40 is fixedly connected to the inner wall of the movable cavity 37;

[0032] During operation, when the fixed block 36 moves, the slider 40 synchronously slides inside the slide groove 41. The combined effect of the slider 40 and the slide groove 41 limits the moving distance of the fixed block 36, thereby preventing the fixed block 36 from moving excessively and escaping from the inside of the active cavity 37 under the action of the restoring force of the spring 38.

[0033] Further, both the front and rear sides of the fixed column 1 are provided with a reflective prompt component, and the reflective prompt component includes a reflective warning sign 42, and two groups of reflective warning signs 42 are provided, and the two groups of reflective warning signs 42 are respectively arranged on the front and rear sides of the fixed column 1, and the reflective warning signs 42 are both sleeved on the outside of the mounting seat 43, and the two groups of mounting seats 43 are respectively fixed on the front and rear sides of the fixed column 1, and the mounting seat 43 is made of cast iron. A magnetic sheet 44 is fixedly connected to the inner wall of the reflective warning sign 42, and the magnetic sheet 44 is attracted to the mounting seat 43. The top of the inner wall of the reflective warning sign 42 is fixedly connected with an insertion rod 45, and the insertion rod 45 is inserted into the inside of the slot 46, and the slot 46 is opened at the top of the mounting seat 43;

[0034] During operation, when replacing or installing the reflective warning sign 42, firstly, the reflective warning sign 42 is mounted on the outside of the mounting seat 43, so that the magnetic sheet 44 and the cast iron mounting seat 43 are attracted to each other, thereby achieving the effect of initially fixing the reflective warning sign 42. When the reflective warning sign 42 is mounted on the outside of the mounting seat 43, the insertion rod 45 is simultaneously inserted into the inside of the slot 46, and the movement of the reflective warning sign 42 is limited by the combined action of the insertion rod 45 and the slot 46, thereby achieving the effect of fixing the reflective warning sign 42.

[0035] Working principle: When the fixed column 1 and the fence 2 are to be assembled, first align the connecting block 31 fixedly connected on the fence 2 with the connecting groove 32, and then insert the connecting block 31 into the connecting groove 32. When the connecting block 31 is inserted into the connecting groove 32, the connecting block 31 squeezes the inclined surface on the fixed block 36, so that the fixed block 36 moves toward the inside of the movable cavity 37 under the action of the squeezing force, and squeezes the spring 38, so that the spring 38 produces elastic deformation. When the connecting block 31 is fully inserted into the connecting groove 32, the squeezing force of the connecting block 31 on the fixed block 36 disappears. At this time, the fixed block 36 returns to its original position under the action of its own restoring force and is inserted into the inside of the fixed groove 35 and engages with the fixed groove 35, which limits the connecting block 31 and makes the fixed column 1 and the fence 2 connected. At this time, the assembly between the fixed column 1 and the fence 2 is completed.

[0036] When the connecting block 31 is inserted into the connecting groove 32, the connecting block 31 simultaneously squeezes the card block 33, so that the card block 33 made of rubber material is squeezed, and the card block 33 is elastically deformed under the action of the squeezing force. When the connecting block 31 is completely inserted into the connecting groove 32, the squeezing force of the connecting block 31 on the card block 33 disappears. At this time, the card block 33 returns to its original state under the action of its own restoring force and engages with the card groove 34, which plays an auxiliary fixation role for the connecting block 31, making the connection between the fixed column 1 and the fence 2 more stable.

[0037] When the fixed block 36 moves, the slider 40 simultaneously slides inside the slide groove 41. The combined effect of the slider 40 and the slide groove 41 limits the moving distance of the fixed block 36, thereby preventing the fixed block 36 from moving excessively and escaping from the inside of the movable cavity 37 under the action of the restoring force of the spring 38.

[0038] When the connection between the fence 2 and the fixed column 1 is to be released and the fixed column 1 and the fence 2 are to be separated, first pull the pull plate 39 to drive the fixedly connected fixed block 36 to move toward the inside of the movable cavity 37, so that the fixed block 36 is released from the engagement with the fixed groove 35, and then the limit on the connecting block 31 is released. At this time, pull the fence 2 away from the fixed column 1 to make the connecting block 31 fall out from the inside of the connecting groove 32, so that the fence 2 and the fixed column 1 can be completely separated.

[0039] When replacing or installing the reflective warning sign 42, the reflective warning sign 42 is first sleeved on the outside of the mounting seat 43, so that the magnetic sheet 44 and the cast iron mounting seat 43 are attracted to each other, thereby achieving the effect of initially fixing the reflective warning sign 42. When the reflective warning sign 42 is sleeved on the outside of the mounting seat 43, the insertion rod 45 is simultaneously inserted into the inside of the slot 46, and the movement of the reflective warning sign 42 is limited by the combined action of the insertion rod 45 and the slot 46, thereby achieving the effect of fixing the reflective warning sign 42.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
