[0019] The present invention will now be described in further detail with reference to the accompanying drawings. Example 1

[0020] like Figure 1 , 2As shown, this utility model discloses a construction sign fixing clamp, including a base 1 and a sign sleeve 2, with a support plate 3 fixedly connected to the bottom end of the sign sleeve 2. The base 1 includes a top plate 11, limiting feet 12 connected to both sides of the top plate, an adjustable fastening screw 13 connected to the lower part of the limiting feet, a crossbar 14 connected to the end of the adjustable fastening screw, and multiple vibration damping springs 51 disposed between the top plate and the support plate. Both the top plate 11 and the support plate 3 have multiple corresponding mounting holes, which are connected by bolt assemblies 5, with each bolt passing through a corresponding vibration damping spring 51. Specifically, there are four vibration damping springs 51, and four sets of corresponding bolt assemblies 5. Additionally, a locking element 4 is provided on the sign sleeve 2 to lock the support rod of the sign.

[0021] Specifically, such as Figure 3-4 As shown, the locking component 4 includes a U-shaped bracket 41, a locking pin 42 mounted on the U-shaped bracket, a support ring 43, a rotating shaft 44, and an eccentric wheel handle 45 fixedly disposed in the middle of the rotating shaft. The U-shaped bracket 41 is mounted on the upper side wall of the sign sleeve 2 via the support ring 43. The rotating shaft 44 is connected to the opening of the U-shaped bracket 41. A through hole for the locking pin to pass through is provided on the side wall of the sign sleeve 2 corresponding to the locking pin 42. Figure 5 As shown, when locking is required, the drive eccentric wheel handle 45 is rotated upward, which can drive the U-shaped bracket 41 to move. Even if the locking pin moves and passes through the through hole, it will squeeze and lock the sign support rod inserted into the sign sleeve 2; thus realizing the quick fastening and installation of the sign.

[0022] Preferably, such as Figure 6 As shown, the top plate and limiting feet of the base can be made of 45# manganese steel, pressed into one piece, with a sheet thickness of 3mm according to national standards. The clamping surface is designed with dimensions (length * width * height) of 30*15*50cm based on calculations. This structure allows for better contact with the clamping body, ensuring the clamp's secure installation. The adjustable fastening screw can be a 12.9*120mm reinforced large-pitch feed screw kit, making tightening installation more efficient. Additionally, a 5cm diameter silicone pad can be placed at the end of the adjustable fastening screw to provide protection and anti-slip properties when in contact with the New Jersey guardrail.

[0023] Furthermore, there are four sets of adjustable fastening screws 13, with two sets arranged on each side of the base.

[0024] In addition, the sign sleeve 2 is made of 6.5*6.5cm square tubing welded together, with the bottom end of the sleeve welded to the base plate as a single unit, forming the sign sleeve structure. The dimensions of the sign sleeve meet the size requirements for the insertion and installation of commonly used sign support rods.

[0025] The damping spring 51 has an outer diameter of 4cm and a height of 3.5cm. It is made of carbon steel with a spring wire diameter of 0.8cm. Carbon steel has high strength and good flexibility, which can better absorb the swaying of the sign caused by natural wind resistance and vehicle resonance.

[0026] This invention's technical solution changes the traditional binding, leaning, and inserting installation methods, greatly improving installation efficiency and post-installation stability, and ensuring high safety during subsequent use. The specific operating method is as follows: When installing a sign on a New Jersey fence, place the base 1 of this invention across the fence, with the bottom surface of the base's top plate contacting the top surface of the fence, and the limiting feet on both sides straddling the fence. Rotate the crossbar 14 to rotate the adjustable fastening screws 13 at the bottom of the limiting feet, moving the adjustable fastening screws 13 towards the side of the fence until the silicone pad 15 presses against the side of the fence. Repeat this operation until all the adjustable fastening screws 13 on the limiting feet are adjusted to the locked position, completing the fixed installation of the base 1. Next, insert the construction control sign support rod into the sign sleeve 2 and lock it in place using the locking device 4. Example 2

[0027] The difference between Example 2 and Example 1 lies in the structure of the locking component. In this example, as shown... Figure 6 , 7 As shown, the locking element 4 is a locking bolt connected to the side wall of the sign sleeve 2. In use, the support rod of the traffic construction control sign is inserted into the sign sleeve, and then the locking bolt is tightened.

[0028] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
