Description

Technical Field

[0001] This utility model relates to the field of high-speed construction auxiliary equipment technology, and in particular to a construction safety sign fixing device. Background Technology

[0002] In highway maintenance operations, the stable placement of construction safety signs is crucial to ensuring the safety of the work area. Traditional methods often use sandbags for ballast or simple supports, which are prone to tipping over and have poor stability. Especially under gusts of wind from traffic or in severe weather, the risk of signs shifting or tipping over is significant, failing to provide continuous and reliable isolation and warning for maintenance work. There is an urgent need for a specialized fixing device that can adapt to the complex environment of highways and be installed securely.

[0003] A search revealed that patent CN221421751U discloses a construction safety sign fixing device for highway maintenance. This device detachably installs a positioning mechanism onto the horizontal guardrail of a bridge section or the guardrail post of a roadbed section, and then uses a load-bearing mechanism to vertically install the construction safety sign, thus completing the installation of the construction safety sign. It is not only reasonably designed and easy to use, but also effectively improves the installation stability of the construction safety sign and can effectively prevent problems such as the construction safety sign being blown down by the wind.

[0004] However, the above-mentioned device has the following drawbacks: First, the device mainly relies on the bottom of the sign contacting the ground and the L-shaped plates clamping the guardrail to achieve stability. The sign is a huge wind-resistant surface, and the wind force will generate a huge overturning moment on it. This moment is entirely resisted by the clamping force and friction of the positioning mechanism, resulting in insufficient wind resistance. Second, the two L-shaped plates can only achieve two-point contact with the guardrail, which is not secure enough. Furthermore, special tools are required to alternately tighten the first and second bolts to achieve installation, making installation and subsequent disassembly and retrieval not quick and convenient. Therefore, further improvement is needed. To this end, we propose a construction safety sign fixing device. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a construction safety sign fixing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a construction safety sign fixing device, comprising a vertical plate, wherein an installation component is fixed at both the bottom and top of the vertical plate, the installation component comprising a U-shaped plate and a V-shaped plate located inside the U-shaped plate, the U-shaped plate being snapped onto the surface of a highway guardrail post, a sign fixing component being fixed on the outer wall of the U-shaped plate located at the top of the vertical plate, and a support component being installed on the surface of the vertical plate away from the opening of the U-shaped plate.

[0007] Furthermore, the U-shaped plate has a through hole on the side near the V-shaped plate, and a sliding rod is slidably connected inside the through hole. The sliding rod is fixedly connected to the V-shaped plate. A screw is threadedly connected to the side wall of the U-shaped plate near the V-shaped plate. One end of the screw is located inside the V-shaped plate and fits against the V-shaped plate. The other end of the screw is fixed with a handle.

[0008] Furthermore, the inner walls of the V-shaped plate and the U-shaped plate are both fixedly connected with tension springs.

[0009] Furthermore, rubber pads are fixed to the inner wall of the U-shaped plate away from the V-shaped plate and on both sides of the V-shaped plate.

[0010] Furthermore, the support assembly includes a horizontal seat fixedly connected to the vertical plate, and a square tube is hinged to the horizontal seat. A square rod is slidably connected inside the square tube, and the bottom end of the square rod is designed with a pointed tip. A first locking bolt is threadedly connected to the bottom side wall of the square tube.

[0011] Furthermore, a sliding sleeve is slidably fitted onto the surface of the vertical plate, and a connecting rod is hinged together with the surface of the sliding sleeve and the surface of the square tube. A second locking bolt is rotatably connected through the side wall of the sliding sleeve via a thread.

[0012] Furthermore, the sign fixing assembly includes a fixing cylinder fixed to the top U-shaped plate, and the top of the fixing cylinder is an open design. The side wall of the fixing cylinder is penetrated and connected to a third locking bolt by a threaded rotation.

[0013] The beneficial effects of this utility model are:

[0014] 1. In use, this utility model includes a vertical plate, two mounting components, and a sign fixing component. Each mounting component consists of a U-shaped plate, a V-shaped plate, and a screw. During installation, the U-shaped plates of both mounting components are clamped onto the surface of the highway guardrail post. Then, the screw is rotated to press the V-shaped plate, utilizing the side walls of the V-shaped and U-shaped plates to press against the highway guardrail post, thus achieving fixation. The V-shaped plate, in conjunction with the U-shaped plate, achieves three-point contact with the post, resulting in a more secure fixation. Furthermore, the two mounting components increase the contact area, making the connection between the device and the highway guardrail post more stable and providing stronger wind resistance. Secondly, this device requires no special tools for installation; it can be installed simply by rotating the screw, making installation simpler and faster.

[0015] 2. When in use, this utility model is equipped with a vertical plate and a support component. After the device is connected to the highway guardrail post through the installation component, it is then in contact with the ground through the support component, which further improves the wind resistance.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-3 As shown, a construction safety sign fixing device is disclosed, including a vertical plate 1. An installation component 2 is fixed at both the bottom and top of the vertical plate 1. The installation component 2 includes a U-shaped plate 21 and a V-shaped plate 24 located inside the U-shaped plate 21. The U-shaped plate 21 is snapped onto the surface of the highway guardrail post. A sign fixing component 4 is fixed to the outer wall of the U-shaped plate 21 located at the top of the vertical plate 1. A support component 3 is installed on the surface of the vertical plate 1 on the side away from the opening of the U-shaped plate 21.

[0024] A through hole 22 is provided on the side of the U-shaped plate 21 near the V-shaped plate 24, and a slide rod 23 is slidably connected inside the through hole 22. The slide rod 23 is fixedly connected to the V-shaped plate 24. A screw rod 25 is threadedly connected to the side wall of the U-shaped plate 21 near the V-shaped plate 24. One end of the screw rod 25 is attached to the V-shaped plate 24, and a handle 26 is fixed to the other end of the screw rod 25.

[0025] When connecting the mounting component 2 to the highway guardrail post, the U-shaped plate 21 is clipped onto the surface of the post, and then the screw 25 is rotated by the handle 26. The screw 25 is used to press the V-shaped plate 24, and the V-shaped plate 24 is used to press against the surface of the post. Whether it is a round post or a square post, the inner wall of the V-shaped plate 24 and the U-shaped plate 21 can have three contact points with the post, thereby increasing the stability of the connection between the mounting component 2 and the post.

[0026] The inner walls of the V-shaped plate 24 and the U-shaped plate 21 are fixedly connected by a tension spring 27.

[0027] When disassembling and retrieving the device from assembly 2, the screw 25 is rotated in the opposite direction. The screw 25 no longer compresses the V-shaped plate 24, and the tension spring 27 pulls the V-shaped plate 24 away from the highway guardrail post. This makes the installation and disassembly of the device relatively simple and quick.

[0028] Rubber pads 28 are fixed to the inner wall of the U-shaped plate 21 away from the V-shaped plate 24 and on both sides of the V-shaped plate 24.

[0029] Rubber pad 28 not only protects the paint on the surface of the post railing, but also increases friction.

[0030] The support assembly 3 includes a horizontal seat 31 fixedly connected to the vertical plate 1, and a square tube 32 is hinged to the horizontal seat 31. A square rod 33 is slidably connected inside the square tube 32, and the bottom end of the square rod 33 is designed with a pointed tip. The bottom side wall of the square tube 32 is penetrated and connected to a first locking bolt 34 by a threaded rotation.

[0031] After the installation component 2 is fixed, rotate the square tube 32 and tilt it at a certain angle to the vertical plate 1, then pull the square rod 33 out along the square tube 32 so that the bottom of the square rod 33 contacts the ground, and then tighten the first locking bolt 34 to press and fix the square rod 33. The support component 3 supports the non-open side of the vertical plate 1 and the U-shaped plate 21, further improving the wind resistance.

[0032] A sliding sleeve 35 is slidably fitted onto the surface of the vertical plate 1. A connecting rod 36 is hinged to the surface of the sliding sleeve 35 and the surface of the square tube 32. A second locking bolt 37 is threaded through the side wall of the sliding sleeve 35 and rotatedly connected to it.

[0033] During the process of pulling the square tube 32 away from the vertical plate 1, the connecting rod 36 will pull the sliding sleeve 35 to move along the surface of the vertical plate 1. Then, the second locking bolt 37 is tightened to press against the surface of the vertical plate 1, thereby fixing the sliding sleeve 35. The connecting rod 36 is used to fix the inclined square tube 32, thereby improving the stability of the square tube 32.

[0034] The sign fixing assembly 4 includes a fixing cylinder 41 that is fixed to the top U-shaped plate 21. The top of the fixing cylinder 41 is open. The side wall of the fixing cylinder 41 is connected to a third locking bolt 42 through a thread.

[0035] When installing the sign, insert the vertical rod of the sign into the fixing cylinder 41, and then tighten the third locking bolt 42 to press and fix the vertical rod of the sign.

[0036] Working principle: During installation, the U-shaped plate 21 of the mounting component 2 is snapped onto the surface of the highway guardrail post. Rotating the screw 25 pushes the V-shaped plate 24 to move, so that it forms a three-point clamping fixation with the inner wall of the U-shaped plate 21. The vertical plate 1 provides the main support, and its bottom mounting component 2 is also fixed to the post. The support component 3 provides additional support by contacting the ground at the bottom of the hinged square tube 32 and the telescopic square rod 33, and locks the angle of the square tube 32 by the sliding sleeve 35 and the connecting rod 36. Finally, the vertical rod of the construction safety sign is inserted into the fixing cylinder 41 of the sign fixing component 4 at the top, and the third locking bolt 42 is tightened to complete the sign fixing.

[0037] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it.
