Description

Technical Field

[0001] The utility model belongs to the technical field of guardrails, and more specifically, particularly relates to a municipal road bridge guardrail. Background Art

[0002] Municipal road guardrail is also called urban traffic galvanized spray steel guardrail. It is beautiful, novel, easy to install, safe and reliable, and affordable. It is suitable for the isolation of urban traffic arteries, green belts in the middle of highways, bridges, secondary roads, township roads and various highway toll gates. Bridge guardrail refers to the guardrail installed on the bridge.

[0003] Based on the above, the inventors have discovered the following problems: current municipal road bridge guardrails are generally formed by integral welding, which makes the guardrails have a certain weight, making it inconvenient for users to move and transport the guardrails. At the same time, since the guardrails need to be assembled in multiple sections, the guardrails are currently mostly assembled by bolt connections, which require a certain amount of time and cost to connect and disassemble, and are not conducive to large-scale assembly operations.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a municipal road bridge guardrail is provided in order to achieve a more practical purpose. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a municipal road bridge guardrail to solve the problems in the current background technology.

DETAILED DESCRIPTION

[0024] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0025] Example:

[0026] As attached Figure 1 To Attachment Figure 4 As shown:

[0027] The utility model provides a municipal road bridge guardrail, including a main body 100 and a connecting mechanism 200, the main body 100 includes a first column 1001 and a second column 1002, a mounting frame 1003 is installed between the first column 1001 and the second column 1002, a plurality of railings 1004 are installed inside the mounting frame 1003, and a mounting seat 1006 is installed at the bottom end of the mounting frame 1003, a sliding rod 1007 is installed on one side of the inner side of the mounting seat 1006, a moving plate 1012 is provided on the outer sliding sleeve of the sliding rod 1007, and a pulley 101 is installed at an equal distance at the bottom end of the moving plate 1012. 3. The connecting mechanism 200 includes a pair of connecting plates 2001 and a fixing frame 2004. A vertical plate 2002 is installed between the pair of connecting plates 2001. The connecting plates 2001 are all arranged on the outside of the first column 1001 and are rotatably connected to the first column 1001 through bearings. Plug holes are arranged inside the connecting plates 2001. The fixing frame 2004 is fixedly arranged on the outside of the second column 1002. A fixing block 2005 is installed outside the fixing frame 2004. A pair of plug rods 2007 are movably inserted inside the fixing block 2005. The plug rods 2007 match the plug holes.

[0028] Among them, a block 2008 is installed at one end of the insertion rod 2007, and the upper and lower ends of the connecting plate 2001 are fixedly installed with a sleeve 2003. The interior of the sleeve 2003 is a regular hexagon, and the sleeve 2003 matches the block 2008. Through the coordinated use of the sleeve 2003 and the block 2008, when the sleeve 2003 rotates with the connecting plate 2001, it drives the block 2008 and the insertion rod 2007 to rotate at the same time.

[0029] A pair of fixing rods 2009 are installed inside the fixing blocks 2005 , one end of each of the fixing rods 2009 extends to the inside of the insertion rod 2007 and is slidably connected to the insertion rod 2007 .

[0030] Among them, the outside of the fixed rod 2009 is movably sleeved with a spring 2010, one end of the spring 2010 is fixedly connected to the inside of the fixed block 2005, and the other end of the spring 2010 is fixedly connected to the insertion rod 2007. By setting the spring 2010, the spring 2010 is squeezed to make the insertion rod 2007 shrink toward the inside of the fixed block 2005. When the spring 2010 is no longer squeezed, the insertion rod 2007 will be reset, so that one end of the insertion rod 2007 is re-located to the outside of the fixed block 2005.

[0031] Among them, a sliding groove is opened on the front side of the fixed block 2005, and a pair of horizontal plates 2006 are slidably connected inside the sliding groove. The horizontal plates 2006 are fixedly connected to the insertion rod 2007. By setting the horizontal plates 2006, when the horizontal plates 2006 are moved, the horizontal plates 2006 will move inside the sliding groove, and at the same time, the horizontal plates 2006 are fixed to the insertion rod 2007, thereby facilitating the movement of the insertion rod 2007 inside the fixed block 2005.

[0032] Among them, the internal rotation of the mounting seat 1006 is connected with a screw rod 1008, one end of which passes through the movable plate 1012 and is threadedly connected to the movable plate 1012. By setting the screw rod 1008, when the screw rod 1008 rotates, the movable plate 1012 connected to its external thread will realize linear movement under the sliding action of the sliding rod 1007.

[0033] Among them, the outer part of the screw 1008 is sleeved with a worm wheel 1009, and the inner part of the mounting seat 1006 is rotatably connected with a worm 1010. The worm 1010 and the worm wheel 1009 are meshed with each other, and one end of the worm 1010 extends to the outside of the mounting seat 1006 and is sleeved with a knob 1011. By setting the knob 1011, it is convenient for the user to turn the knob 1011 to rotate the worm 1010. Since the worm 1010 is meshed with the worm wheel 1009, the worm wheel 1009 rotates and drives the screw 1008 to rotate.

[0034] Among them, reflective strips 1005 are bonded to the front and back of the railing 1004. By setting the reflective strips 1005, protection is provided for driving or pedestrians at night.

[0035] The specific usage and function of this embodiment are as follows:

[0036] When using this product, first check whether the various internal mechanisms of the municipal road bridge guardrail are complete. After ensuring that they are complete, turn the knob 1011 to rotate the worm 1010 to drive the worm wheel 1009 to rotate, so that the screw 1008 rotates. When the movable plate 1012 connected to its external thread moves to the bottom of the mounting seat 1006 under the sliding action of the slide bar 1007, the pulley 1013 at the bottom of the movable plate 1012 will be exposed, so that the user can move the guardrail to the specified position, and then move the cross plate 2006 to move the insertion rod 2007 on the fixed rod 2009 and squeeze the spring 2010 sleeved on the outside of the fixed rod 2009, so that the insertion rod 2007 shrinks to the inside of the fixed block 2005 , place the fixed block 2005 at the second column 1002 of one of the guardrails between a pair of connecting plates 2001 at the first column 1001 of the other guardrail, and then loosen the cross plate 2006, the plug rod 2007 and the block 2008 will pass through the insertion hole of the connecting plate 2001, and the block 2008 will be placed in the sleeve 2003, so as to realize the quick connection between the guardrails. When there is a bend in the terrain where the guardrail needs to be placed, the connecting plate 2001 is rotated according to the curvature. Since the sleeve 2003 and the block 2008 on the connecting plate 2001 match, when the sleeve 2003 rotates with the connecting plate 2001, the block 2008 and the plug rod 2007 are driven to rotate at the same time, so as to facilitate the adjustment of the angle of the connection between a pair of guardrails.
