Description

Technical Field

[0001] This utility model relates to the field of sign technology, and in particular to a sign fixing bracket. Background Technology

[0002] With the rapid advancement of transportation infrastructure construction such as highways and municipal roads in my country, the road mileage continues to grow. The expansion of the transportation network has placed higher demands on road safety signage systems. As the core carrier for conveying road conditions, guiding traffic, and warning of risks, the stable installation of signs is directly related to driving safety.

[0003] Currently, existing sign fixing brackets generally adopt an installation method of fixing with a cement base and bolts and nuts. First, a cement base is poured at the designated location. After the base solidifies, the fixing bracket is then fixed to the base using bolts and nuts. On the one hand, the construction of the cement base not only requires additional materials and time costs, but also, once solidified, its position is completely fixed. If the bracket needs to be moved due to road planning adjustments or changes in signage requirements, the original base must be dismantled and rebuilt, resulting in poor flexibility. On the other hand, traditional brackets and signs are mostly fixedly connected. When the signage content needs to be adjusted according to the scenario, the entire bracket structure must be disassembled or modified, leading to low maintenance efficiency. Utility Model Content

[0004] To solve the above problems, this utility model provides a sign fixing bracket.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sign fixing bracket, comprising a support tube for installing the sign and two fixing plates, wherein a first threaded hole is provided on the fixing plate, and a first bolt is spirally arranged in the first threaded hole; two vertically spaced triangular frames are provided on the two fixing plates, and a vertically arranged mounting plate is provided on the side of the two triangular frames away from the fixing plates; a second threaded hole is horizontally provided on the mounting plate, and a first threaded rod is spirally arranged in the second threaded hole; a connecting seat is rotatably arranged at the end of the first threaded rod near the fixing plate; a pressure plate is rotatably arranged on the connecting seat; a mounting tube is vertically arranged on the two triangular frames between the two fixing plates; the support tube and the mounting tube are inserted into each other; and a fixing component for fixing the support tube is provided on the mounting tube.

[0006] By adopting the above technical solution, a support pipe, a fixing plate, and a triangular frame are installed. This fixing bracket is placed on the concrete guardrail, with the lowermost triangular frame contacting the top of the guardrail. The fixing plate and mounting plate are located on either side of the guardrail. The position of the first bolt is adjusted by rotating it until its end contacts the side wall of the guardrail. Then, the first threaded rod is rotated, causing the connecting seat and pressure plate to move. The pressure plate then contacts the concrete guardrail and can rotate relative to the connecting seat to accommodate the sloping side of the concrete, thus fixing the bracket to the concrete guardrail. When the bracket needs to be moved, it can be disassembled by loosening the first bolt and the first threaded rod, and then moved to the designated position for installation, offering high flexibility. The plug-in connection between the support pipe and the mounting pipe, combined with the fixing components, allows for quick installation and removal of the sign, resulting in high maintenance efficiency.

[0007] Furthermore, a first hinge seat is provided on the side of the mounting plate near the fixed plate, a connecting rod is rotatably provided on the first hinge seat, a sliding tube is slidably sleeved on the connecting rod, and a second hinge seat connected to the pressure plate is rotatably provided at the end of the sliding tube away from the first hinge seat.

[0008] By adopting the above technical solution, a first hinge seat, a connecting rod, a sliding tube, and a second hinge seat are provided. The cooperation of the first hinge seat, the second hinge seat, the connecting rod, and the sliding tube forms a movable support structure. This structure can guide and limit the movement direction of the pressure plate as it moves with the first threaded rod, preventing the pressure plate from rotating or shifting around the first threaded rod during clamping. Simultaneously, the sliding tube can extend and retract along the connecting rod to adapt to different movement distances of the pressure plate, ensuring the pressure plate's condition and improving the reliability of the clamping effect.

[0009] Furthermore, support plates are provided on both sides of the lower triangular frame.

[0010] By adopting the above technical solution, the support plates on both sides of the lower triangular frame are increased to enhance lateral support. This ensures stability in windy weather and further strengthens the support stability at the bottom of the frame.

[0011] Furthermore, connecting plates are respectively provided on both sides of the triangular frame, and circular holes are provided on the connecting plates. A second threaded rod is vertically provided on the support plate, and the upper end of the second threaded rod passes through the circular hole and is screwed with a first nut.

[0012] By adopting the above technical solution, a connecting plate, a circular hole, and a second threaded rod are provided to achieve adjustment of the support plate. By loosening the first nut, the support plate can be rotated along the second threaded rod to adjust its angle for storage or support.

[0013] Furthermore, the mounting tube has three circumferentially spaced through holes, and the fixing component includes three second nuts disposed on the outer wall of the mounting tube. The three second nuts correspond one-to-one with the three through holes, and a second bolt is spirally disposed inside the second nut.

[0014] By adopting the above technical solution, a second nut and a second bolt are set. Rotating the second bolt can make its end press against the outer wall of the support pipe. The three points of uniform force can effectively limit the rotation and axial movement of the support pipe in the installation pipe.

[0015] Furthermore, the pressure plate has several vertically spaced horizontal teeth on one side near the fixing plate.

[0016] By adopting the above technical solution, the vertical horizontal teeth on the pressure plate can increase the friction between the pressure plate and the concrete guardrail contact surface. This prevents the pressure plate from slipping, further strengthens the clamping effect of the pressure plate, and improves the overall anti-displacement capability of the fixed bracket.

[0017] Furthermore, several conical nails are horizontally spaced at both the upper and lower parts of the side of the pressure plate adjacent to the fixing plate.

[0018] By adopting the above technical solution, the horizontal conical nails at the top and bottom of the pressure plate can penetrate into the substrate surface when the pressure plate is clamped, forming a physical interlocking fixation. The conical nails cooperate with the cross teeth to improve the connection strength between the pressure plate and the concrete guardrail through frictional anti-slip and physical embedding, which can effectively prevent the pressure plate from loosening and enhance the stability of the fixing bracket.

[0019] Furthermore, a hexagonal block is provided at the end of the first threaded rod away from the connecting seat.

[0020] By adopting the above technical solution, the hexagonal block at the end of the first threaded rod can be adapted to common tools such as wrenches, making it convenient for operators to quickly rotate the first threaded rod.

[0021] Furthermore, the fixing plate is an L-shaped steel plate.

[0022] In summary, this utility model has the following beneficial effects: In this application, a support pipe, a fixing plate, and a triangular frame are provided. The fixing bracket is placed on a concrete guardrail, with the lowermost triangular frame contacting the top of the concrete guardrail. The fixing plate and mounting plate are located on opposite sides of the concrete guardrail. The position of the first bolt is adjusted by rotating it, so that the end of the first bolt contacts the side wall of the concrete guardrail. Then, the first threaded rod is rotated, causing the connecting seat and pressure plate to move. The pressure plate abuts against the concrete guardrail and can rotate relative to the connecting seat to adapt to the sloping side of the concrete, thus fixing the fixing bracket to the concrete guardrail. When the fixing bracket needs to be moved, it can be disassembled by loosening the first bolt and the first threaded rod, and then moved to the designated position for installation, offering high flexibility. The plug-in connection between the support pipe and the mounting pipe, combined with the fixing components, allows for quick installation and disassembly of the sign, resulting in high maintenance efficiency.

Detailed Implementation

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0029] like Figure 1-4As shown in the embodiment of this application, a sign fixing bracket is disclosed, including a support tube 10, a fixing plate 20, and a mounting plate 40. The sign is installed on the upper end of the support tube 10. A first threaded hole is horizontally opened on the fixing plate 20, and a first bolt 21 is spirally arranged in the first threaded hole. There are two fixing plates 20, and two vertically spaced triangular frames 30 are arranged on the two fixing plates 20. The mounting plate 40 is arranged on the side of the two triangular frames 30 away from the fixing plate 20 and is connected to the two triangular frames 30 and arranged vertically. A second threaded hole is horizontally opened on the mounting plate 40, and a first threaded rod 41 is spirally arranged in the second threaded hole. A connecting seat 42 is rotatably arranged on the end of the first threaded rod 41 near the fixing plate 20. A pressure plate 43 is rotatably arranged on the connecting seat 42. The mounting tube 31 is vertically arranged on the two triangular frames 30 between the two fixing plates 20. The support tube 10 and the mounting tube 31 are inserted and matched. A fixing component 50 for fixing the support tube 10 is provided on the mounting tube 31.

[0030] The fixing bracket is placed on the concrete guardrail along the highway, with the lowest triangular bracket 30 contacting the top of the concrete guardrail. The fixing plate 20 and mounting plate 40 are located on both sides of the concrete guardrail. The position of the first bolt 21 is adjusted by rotating it so that the end of the first bolt 21 contacts the side wall of the concrete guardrail. Then, the first threaded rod 41 is rotated, causing the connecting seat 42 and the pressure plate 43 to move. The pressure plate 43 abuts against the concrete guardrail and can rotate relative to the connecting seat 42 to adapt to the sloping side of the concrete, thus fixing the fixing bracket to the concrete guardrail. When the fixing bracket needs to be moved, the first bolt 21 and the first threaded rod 41 can be loosened to complete the disassembly, and then it can be moved to the designated position for installation, which is highly flexible. The plug-in cooperation between the support pipe 10 and the mounting pipe 31, combined with the fixing component 50, allows for the quick installation and disassembly of the sign, resulting in high maintenance efficiency.

[0031] Specifically, the fixing plate 20 is an L-shaped steel plate. A hexagonal block 46 is provided at the end of the first threaded rod 41 furthest from the connecting seat 42, which can be fitted with common tools such as wrenches, allowing operators to quickly rotate the first threaded rod 41. Compared to a threaded rod without an auxiliary structure, the hexagonal block 46 improves the efficiency of force application, prevents slippage during manual rotation, simplifies the adjustment steps during bracket installation, and improves installation efficiency.

[0032] During setup, a first hinge seat 60 is provided on the side of the mounting plate 40 adjacent to the fixed plate 20. A connecting rod 61 is rotatably mounted on the first hinge seat 60, and a sliding tube 62 is slidably sleeved on the connecting rod 61. A second hinge seat 63, connected to the pressure plate 43, is rotatably mounted on the end of the sliding tube 62 away from the first hinge seat 60. The cooperation of the first hinge seat 60, the second hinge seat 63, the connecting rod 61, and the sliding tube 62 forms a movable support structure. This structure guides and limits the movement direction of the pressure plate 43 as it moves with the first threaded rod 41, preventing the pressure plate 43 from rotating or shifting around the first threaded rod 41 during clamping. Simultaneously, the sliding tube 62 can extend and retract along the connecting rod 61 to accommodate different movement distances of the pressure plate 43, ensuring the state of the pressure plate 43 and improving the reliability of the clamping effect.

[0033] To prevent the sign from swaying sideways under the impact of strong winds and airflow from vehicles, support plates 70 are installed on both sides of the lower triangular frame 30. These support plates 70 on both sides of the lower triangular frame 30 increase lateral support, ensuring stability in windy weather and further enhancing the stability of the support base. Connecting plates 71 are installed on both sides of the triangular frame 30, each with a circular hole. A second threaded rod 72 is vertically installed on the support plate 70, with its upper end passing through the circular hole and screwed with a first nut 73. The connecting plates 71, the circular hole, and the second threaded rod 72 allow for adjustment of the support plate 70. By loosening the first nut 73, the support plate 70 can be rotated along the second threaded rod 72 to adjust its angle for storage or support.

[0034] In a specific configuration, the pressure plate 43 has several vertically spaced horizontal teeth 44 on one side adjacent to the fixing plate 20. These vertical teeth 44 increase the friction between the pressure plate 43 and the concrete guardrail, preventing slippage and further enhancing the clamping effect, thus improving the overall anti-displacement capability of the fixing bracket. Several horizontally spaced conical nails 45 are also provided on the upper and lower parts of the side of the pressure plate 43 adjacent to the fixing plate 20. These horizontal conical nails 45 can penetrate the substrate surface when the pressure plate 43 is clamped, forming a physical interlocking fixation. The conical nails 45, in conjunction with the horizontal teeth 44, enhance the connection strength between the pressure plate 43 and the concrete guardrail through frictional anti-slip and physical embedding, effectively preventing the pressure plate 43 from loosening and enhancing the stability of the fixing bracket.

[0035] The mounting tube 31 has three circumferentially spaced through holes. The fixing assembly 50 includes three second nuts 51 disposed on the outer wall of the mounting tube 31, each corresponding to one of the three through holes. A second bolt 52 is screwed inside each second nut 51. The three circumferentially spaced second nuts 51 and second bolts 52 form a multi-point fixation for the support tube 10. Rotating the second bolt 52 causes its end to press against the outer wall of the support tube 10. The three points of even force effectively restrict the rotation and axial movement of the support tube 10 within the mounting tube 31, resulting in a more secure fixation compared to single-point fixing.

[0036] The operating principle of the sign fixing bracket in this embodiment is as follows: The sign fixing bracket is placed on a concrete guardrail, with the lowest triangular bracket 30 contacting the top of the guardrail, and the fixing plate 20 and mounting plate 40 separated from both sides of the guardrail. The first bolt 21 in the first threaded hole of the fixing plate 20 is rotated until its end touches the side wall of the guardrail. The first threaded rod 41 with a hexagonal block 46 in the second threaded hole of the mounting plate 40 is rotated, causing the connecting seat 42 and pressure plate 43 to move, so that the horizontal bar 44 and conical nail 45 touch the guardrail. If the support plate 70 needs adjustment, the first nut 73 of the second threaded rod 72 on the connecting plate 71 is loosened, and the support plate 70 is rotated to a suitable angle before tightening the first nut 73. When installing the sign, the support tube 10 is inserted into the mounting tube 31, and the second bolts 52 in the three circumferentially spaced second nuts 51 on the outer wall of the mounting tube 31 are rotated until their ends press against the support tube 10 to complete the fixing. When disassembling and moving, loosen the first bolt 21 and the first threaded rod 41, and the sign fixing bracket can be moved to the designated position. Repeat the above steps for installation.

[0037] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
