[0002] Traffic facilities refer to various facilities and equipment set up to promote smooth and safe transportation. Among them, during traffic construction, guardrails can prevent pedestrians from entering the construction area to avoid danger. Usually, guardrails are spliced ​​and used in combination. When splicing, it is necessary to use a connecting device to connect the two adjacent guardrails together.

[0003] After searching, the authorization announcement number CN218438640U and the authorization announcement date 2023.02.03 disclose a device for adding anti-collision guardrails for the construction of road traffic safety facilities, including a guardrail rod and a adding device, the guardrail rod is arranged symmetrically about the ground, a base plate is installed at the bottom of the guardrail rod, and connecting plates are symmetrically arranged at the inner end of the guardrail rod, the connecting plate and the guardrail rod are connected by a first bolt, and the inner end of the connecting plate is installed with a adding device. The utility model adopts a limit cavity and a limit plate structure, which is convenient for adding and disassembly and replacement, and a bellows structure is used to protect the device to prevent rain from causing rust to the internal structure.

[0004] The prior art reinforces the stability of the limit plate by the mutual attraction between the first magnet and the second magnet. However, the magnetic force provided by the magnet is relatively small, resulting in poor stability when the limit plate is reinforced by the magnet. The prior art uses bolts to fix the connecting plate to the guardrail rod. However, in actual use, the connection plate needs to be disassembled and assembled using a wrench to tighten the bolts, which is cumbersome to operate. For this reason, we provide a connection device for traffic safety construction guardrail to solve the above problems. Utility Model Content

The above arrangement improves the stability of the two movable plates 203 through the threaded connection between the screw 202 and the two movable plates 203, so that the stability during use is better.

[0030] Specifically, the movable plate 203 is L-shaped, and the right end of the movable plate 203 is clearance-matched with the mounting frame 205 to prevent the movable plate 203 from shaking. The movable plate 203 is threadedly connected to the screw rod 202 .

[0031] The screw rod 202 is rotatably connected to the fixed frame 204 through a bearing. The fixed frame 204 and the installation frame 205 are respectively fixedly connected to the corresponding guardrail rod 102. The fixed frame 204 and the installation frame 205 are both circularly arranged. A screw block 201 is fixed to the upper end of the screw rod 202. The screw rod 202 can be rotated by rotating the screw block 201.

[0032] The screw block 201 is circular in shape, and an anti-slip pattern 2011 is formed on the outer wall of the screw block 201 to increase the friction between the hand and the screw block 201 when the screw block 201 is screwed.

[0034] The operation process of this embodiment is: when connecting the fixed frame 204 with the installation frame 205, the screw 202 is rotated by operating the screw block 201 to drive the two movable plates 203 to approach each other, and then the right end of the movable plate 203 is inserted into the installation frame 205, and then the screw block 201 is reversely operated to rotate to drive the movable plates 203 to move away from each other until the right end of the movable plate 203 is located outside the installation frame 205. At this time, the bolt 2031 is operated to thread the movable plate 203 with the boss 2051. Specific embodiment 2

[0036] See also Figure 1 , 4 5 is a second embodiment of the present invention, which is based on the previous embodiment, but is different from the first embodiment in that: a guardrail assembly 1 is provided on both sides of the addition assembly 2, and the guardrail assembly 1 includes a guardrail rod 102, and a fixing cap 101 is provided on the outer side of the upper end of the guardrail rod 102, and the fixing cap 101 is adapted to the guardrail rod 102, and a plug rod 103 is inserted on the front side of the fixing cap 101, and the rear end of the plug rod 103 is inserted into the front wall of the guardrail rod 102. At this time, under the action of the plug rod 103, the fixing cap 101 is connected to the corresponding guardrail rod 102. For fixation, a return spring 104 is provided on the outside of the insertion rod 103 to apply a force to the baffle 1032 in the direction of the guardrail rod 102 to prevent the insertion rod 103 from accidentally detaching from the guardrail rod 102 during use. A mounting plate 105 is provided on the outside of the insertion rod 103 at the front end of the return spring 104 corresponding to the baffle 1032 is fixed on the outside of the insertion rod 103 at the rear end of the return spring 104 corresponding to the insertion rod 103. The above arrangement enables the rear end of the insertion rod 103 to enter or detach from the front wall of the corresponding guardrail rod 102, so as to achieve rapid disassembly and assembly of the fixing cap 101 and the guardrail rod 102.

[0037] Specifically, the cross-section of the insertion rod 103 is rectangular, and a pinch block 1031 is fixed to the front end of the insertion rod 103. The pinch block 1031 is operated to move the interface forward to make the insertion rod 103 detach from the guardrail rod 102, and the pinch block 1031 is in the shape of a quadrangular pyramid.

The lower end of the guardrail rod 102 is fixed with a bottom plate 1021, and the bottom plate 1021 is connected to the ground.

[0038] The rear wall of the baffle 1032 is in contact with the front wall of the fixing cap 101, and the length of the upper wall of the insertion rod 103 is greater than the length of the lower wall of the insertion rod 103, so that the rear end of the insertion rod 103 is an inclined surface. Through this inclined surface, when the fixing cap 101 is installed, the insertion rod 103 moves down to cover the guardrail rod 102, and the insertion rod 103 can be smoothly inserted into the inside of the front wall of the guardrail board without operating the pinch block 1031 to move forward.

[0039] The rest of the structure is the same as that of the first embodiment.

[0040] The operation process of this embodiment is: the fixing cap 101 is operated to be sleeved on the outside of the corresponding guardrail rod 102 to achieve installation. When disassembling, the insertion rod 103 is driven forward by operating the pinch block 1031 to move forward, so that the insertion rod 103 is separated from the guardrail rod 102. At this time, the fixing cap 101 is operated to move upward to separate the fixing cap 101 from the guardrail rod 102.
