[0031] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0032] like Figures 1-8As shown, this embodiment discloses a fixing structure for a bridge road guardrail, including a base 1. The top of the base 1 has an opening, and the inner bottom wall has a positioning groove 2 corresponding to the opening. A movable block 3 is slidably connected to the inner bottom wall of the base 1. A limiting rod 4 is fixed on the side near the positioning groove 2. The limiting rod 4 is inserted into the limiting hole 501 at the bottom of the column 5. A movable block 6 is located on the side of the movable block 3 away from the limiting rod 4. The movable block 6 is set as an inclined surface on the side near the movable block 3. The inclined surface extends from bottom to top towards the movable block 3 and contacts the movable block 3. A spring 7 is set between the movable block 3 and the positioning groove 2, and its two ends are fixedly connected to the movable block 3 and the positioning groove 2, respectively. A height adjustment component 8 is set on the base 1. The height adjustment component 8 drives the movable block 6 to move up and down in the vertical direction.

[0033] In this embodiment, the base 1 includes a lower box 101 and an upper box 102. The upper box 102 is fixed to the middle of the top surface of the lower box 101. The upper box 102 and the lower box 101 are interconnected, and the opening is set at the top of the upper box 102. The positioning groove 2 is fixed on the inner bottom wall of the lower box 101. The peripheral side wall of the bottom of the column 5 contacts and cooperates with the inner wall of the positioning groove 2, and the peripheral side wall of the limiting rod 4 contacts and cooperates with the hole wall of the limiting hole 501.

[0034] In use, the lower box 101 is first embedded in the concrete of the bridge pavement structure, with the top surface of the lower box 101 flush with the pavement. Then, the bottom of the column 5 is inserted into the positioning groove 2 through the opening, and the limiting hole 501 at the bottom of the column 5 corresponds to the limiting rod 4. After that, the height adjustment component 8 drives the movable block 2 6 to move vertically downward. During the downward movement of the movable block 2 6, its inclined surface continuously squeezes the movable block 3, causing the movable block 3 to move towards the column 5 until the limiting rod 4 is inserted into the limiting hole 501, and then the installation of the column 5 is completed.

[0035] When the column 5 needs to be disassembled, the height adjustment component 8 first drives the movable block 6 to move vertically upward. Since the spring 7 is in a compressed state, the spring 7 will cause the movable block 3 to move away from the column 5 under the action of the rebound force until the limit rod 4 is dislodged from the limit hole 501, and then the column 5 can be lifted upward.

[0036] By adopting this solution, the structure described above allows for a detachable connection between the column 5 and the base 1. When the column 5 is damaged, it is easy to disassemble and replace it, which not only saves a lot of labor costs but also significantly shortens the maintenance time of the guardrail.

[0037] Further optimizing the design, the height adjustment component 8 includes a vertically arranged threaded rod 81. The bottom of the threaded rod 81 passes through the movable block 6 and is rotatably connected to the bottom wall of the base 1. The top movable seal passes through to the outside of the base 1 and is connected to the drive disc 82. The threaded rod 81 is threadedly connected to the movable block 6. A vertically arranged guide rod 83 is provided on one side of the threaded rod 81. Both the upper and lower ends of the guide rod 83 are fixedly connected to the inner wall of the base 1, and the guide rod 83 slides in cooperation with the movable block 6.

[0038] In this embodiment, the top of the threaded rod 81 is rotatably sealed to the top wall of the lower housing 101 through a rotary seal, the top surface of the threaded rod 81 is fixedly connected to the middle of the drive disk 82, and a handle is fixed at the edge of the top surface of the drive disk 82.

[0039] Using this scheme, the drive disc 82 is rotated to drive the threaded rod 81 to rotate, and under the guidance of the guide rod 83, the movable block 6 can move up and down in the vertical direction.

[0040] Further optimization of the design includes a locking nut 84, which is threaded onto the threaded rod 81, with its bottom surface resting against the top surface of the base 1. The locking nut 84 allows for locking or unlocking of the threaded rod 81; when the threaded rod 81 is locked, the bottom surface of the locking nut 84 rests against the top surface of the lower housing 101.

[0041] In a further optimized design, two spaced-apart guide strips 10 are fixed to the inner bottom wall of the base 1. The two guide strips 10 are located on either side of the movable block 3, and the bottom sidewall of the movable block 3 slides in conjunction with the guide strips 10. In this embodiment, the guide strips 10 are fixed to the inner bottom wall of the lower housing 101. The guide strips 10 ensure that the movable block 3 can only move in a straight line towards or away from the column 5.

[0042] Further optimization of the scheme also includes a cover 11, which is detachably connected to the opening at the top of the base 1; the cover 11 includes two parts, namely, a first part 111 and a second part 112, which are interlocked and connected, and the first part 111, the second part 112, and the column 5 are all sealed together.

[0043] In this embodiment, an elastic pad 113 is fixed on the side wall of the middle part of the first part 111, and an elastic pad 214 is fixed on the side wall of the middle and side parts of the second part 112. The first part 111, the second part 112, and the column 5 are sealed together by the elastic pad 113 and the elastic pad 214.

[0044] When installing the cover 11, the first part 111 and the second part 112 are first inserted into each other and fastened to the outer periphery of the column 5. Then, the first part 111 and the second part 112 are moved downward as a whole and installed at the top opening of the upper box 102. After the cover 11 is installed, the peripheral side wall of the top of the upper box 102 is inserted into the gap 117 at the bottom of the first part 111 and the second part 112.

[0045] To further optimize the design, each end of split-body 111 near split-body 112 has a plug-in block 115 fixed to it. Split-body 112 has plug-in slots 116 corresponding to the plug-in blocks 115. The plug-in blocks 115 are plugged into the corresponding slots 116. Through the plug-in blocks 115 and the plug-in slots 116, the plug-in connection between split-body 111 and split-body 112 can be achieved.

[0046] To further optimize the scheme, multiple sets of elastic pressing mechanisms 9 are provided between the opening and the positioning groove 2. The multiple sets of elastic pressing mechanisms 9 are arranged in pairs on the inner wall of the base 1. The elastic pressing mechanism 9 includes two sets of horizontally spaced elastic telescopic components 91. The moving ends of the two sets of elastic telescopic components 91 are connected to a horizontally arranged connecting shaft 92. A pressing roller 93 is rotatably connected to the connecting shaft 92.

[0047] In this embodiment, four sets of elastic pressing mechanisms 9 are configured, with each set corresponding to the next on the inner wall of the upper housing 102. After the column 5 is installed, the elastic telescopic component 91 is in a compressed state, and the side of the pressing roller 93 abuts against the side wall of the column 5. By configuring multiple sets of elastic pressing mechanisms 9, the stability of the column 5 after installation can be further improved.

[0048] Further optimization of the scheme: the elastic telescopic component 91 includes a telescopic rod 911 set on the inner wall of the base 1, an installation block 912 fixedly connected to the actuating end of the telescopic rod 911, and a connecting shaft 92 fixedly connected to the installation block 912; a second spring 913 is sleeved on the outer periphery of the telescopic rod 911, and the two ends of the second spring 913 are respectively connected to the inner wall of the base 1 and the installation block 912.

[0049] In this embodiment, the telescopic rod 911 can only extend and retract within a certain range. The fixed end of the telescopic rod 911 is fixed to the inner wall of the base 1, and the two ends of the spring 913 abut against the inner wall of the base 1 and the mounting block 912, respectively. After the column 5 is installed, the telescopic rod 911 retracts, the spring 913 is compressed, and the pressure roller 93 abuts against the side wall of the column 5. Through the telescopic rod 911, the mounting block 912, and the spring 913, the effect of providing a pressing force to the pressure roller 93 can be achieved.

[0050] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
