[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figure 1-4 As shown, this utility model is a prefabricated portable fixing device for temporary highway facilities, comprising:

[0027] The fixing component includes a sleeve 11, an internal threaded ring 12, a turntable 15, a threaded rod 16, a handle 17, and a support rod 18. The internal threaded ring 12 is disposed at one end of the outer surface of the sleeve 11, the threaded rod 16 is threadedly connected to the middle of the internal threaded ring 12, the handle 17 is fixedly connected to one end of the outer surface of the threaded rod 16, the turntable 15 is disposed at the other end of the outer surface of the threaded rod 16, and the support rod 18 is inclinedly disposed at the outer end of the turntable 15.

[0028] Through the provided fixing components, the threaded rod 16 drives the support rod 18 to extend, and cooperates with the pin 13 to rotate and tighten the guardrail plate via the rotating shaft 19, forming a stable triangular force structure, which firmly fixes the sleeve to the post, so that the sleeve will not rotate or fall off, greatly improving the installation firmness and protection reliability of the fixing components.

[0029] An opening is provided at the other end of the outer surface of the sleeve 11, and the opening is adapted to the bolt of the anti-blocking block;

[0030] The pre-set opening structure of sleeve 11 is precisely matched with the bolt size and position of the guardrail anti-blocking block. Through the fitting and limiting of the opening and the bolt, the initial displacement of the device in the axial and circumferential directions of the column is further constrained, establishing a stable assembly benchmark for subsequent fastening operations and preventing the device from shifting during the assembly process.

[0031] Support frames 14 are welded to the top and bottom of the outer surface of the support rod 18, and a rotating shaft 19 is provided on the inner surface of the support frame 14.

[0032] A pin 13 is rotatably connected between the rotating shafts 19, and the pin 13 is located at the outer end of the support rod 18.

[0033] The pin 13 is connected to the main body of the device through two symmetrically arranged rotating shafts 19. Under the combined action of the driving force of the threaded rod 16 and the supporting force of the support rod 18, the pin 13 rotates around the rotating shaft 19, and its end gradually approaches the surface of the guardrail and finally presses tightly against the guardrail.

[0034] A top plate 21 is fixed to the top of the sleeve 11, and a vertical rod 22 is welded to the middle of the top of the top of the top plate 21;

[0035] The sign can be fixed to the outside of the pole 22 with fasteners.

[0036] Working principle:

[0037] First, the sleeve 11 is precisely fitted onto the guardrail post. Then, when the operator manually turns the handle 17, the threaded rod 16, which is fixed to the handle 17, rotates in the middle of the internal threaded ring 12. The internal threaded ring 12 is fixed to the main frame of the device, and the internal thread on its inner wall forms a helical pair with the external thread of the threaded rod 16, converting the rotational motion of the threaded rod 16 into a linear driving force along the thread axis. Since the support rods 18 on both sides are connected to the threaded rod 16 through the turntable 15, the turntable 15 can rotate synchronously with the rotation of the threaded rod 16 and drive the support rods 18 on both sides. The linkage is activated. Driven by the threaded rod 16, the two support rods 18 extend smoothly along the side of the guardrail with the main body of the device as the base point. When the two support rods 18 extend to touch the lower edge of the protruding part in the middle of the guardrail, the manual handle 17 is rotated. The threaded rod 16 continues to apply driving force. The pin 13 is connected to the main body of the device through two symmetrically arranged rotating shafts 19. Under the combined action of the driving force of the threaded rod 16 and the supporting force of the support rods 18, the pin 13 rotates around the rotating shaft 19, and its end gradually approaches the surface of the guardrail and finally presses tightly against the guardrail.

[0038] This step, through the formation of a stable triangular force-bearing structure with three points of support—the positioning point of the column-sleeve 11, the contact point between the support rod 18 and the guardrail panel, and the tightening point between the pin 13 and the guardrail panel—firmly fixes the sleeve to the column, preventing the sleeve from rotating or falling off, and greatly improving the installation firmness and protection reliability of the fixing components.

[0039] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes:

[0040] The fixing component includes a first support plate 31, a positioning rod 32, a second support plate 33, and a positioning hole 34. The first support plate 31 is fixed to the outer end of the turntable 15, the second support plate 33 is fixed between the ends of the support rods 18, the positioning rod 32 is fixed to the middle of one end of the second support plate 33, and the positioning hole 34 is opened in the middle of one end of the first support plate 31, with the positioning rod 32 inserted into the interior of the positioning hole 34.

[0041] The threaded drive and plug-in design reduces the tedious disassembly steps, shortens the disassembly and assembly time during the maintenance and replacement of guardrail devices, and significantly improves work efficiency.

[0042] The upper and lower parts of the second support plate 33 are provided with insertion holes 37, and the upper and lower parts of the first support plate 31 are provided with insertion rods 35. The insertion rods 35 are inserted into the interior of the insertion holes 37, and the external threads of the insertion rods 35 are connected to a fixing ring 36. The fixing ring 36 is tightly attached to the other end of the second support plate 33.

[0043] As the retaining ring 36 continues to rotate, the thread engagement length between it and the insert rod 35 gradually shortens until the retaining ring 36 completely disengages from the threaded section of the insert rod 35. At this point, the axial constraint of the insert rod 35 is completely released, providing conditions for subsequent separation operations.

[0044] Working principle:

[0045] First, when the operator manually rotates the fixing ring 36, the internal thread on the inner wall of the fixing ring 36 will undergo relative spiral motion with the external thread on the outer wall of the insertion rod 35. As the fixing ring 36 continues to rotate until it is completely disengaged from the threaded section of the insertion rod 35, the operator applies a pulling force to the two support rods 18. The pulling force is directly transmitted to the insertion rod 35, causing the insertion rod 35 to move outward along the axis of the insertion hole 37, thus completely breaking the connection between the support plate 1 31 and the support plate 2 33.

[0046] This step involves initial secure locking of the support rod 18 through threaded engagement, releasing the threaded constraint via the rotational movement of the retaining ring 36, and finally completing separation using the convenience of the plug-in structure. The entire process requires only manual operation.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification.
