[0001] This utility model relates to the field of building engineering technology, and in particular to a building engineering safety warning device. Background Technology

[0002] Construction sites often present various safety hazards, such as falls from heights, being struck by objects, and electric shocks. Safety warning signs can alert workers and passersby to the dangers, thereby preventing accidents from occurring.

[0003] By writing warning signs on a writing pad, a warning effect can be achieved for staff. For example, the existing technology disclosed in Chinese Patent Publication No. "CN219117988U" is a construction engineering safety warning device, which relates to the field of construction engineering technology. It includes a frame and a support rod. The support rod is installed above the frame, and a warning sign is installed at the upper end of the support rod. A screw groove is installed above the warning sign, and a screw rod is installed in the screw groove. A slider is connected to the screw rod by a thread, and a cam is connected to the slider by a motor. The rotation of the cam can support the dust removal plate that is installed on the slider by a spring. When the cam rotates to a small arc, the dust removal plate will rebound, thereby vibrating and cleaning the dust. There is an angle between the dust removal plate and the warning sign. Under the elastic force of the spring, the dust removal plate is in contact with the warning sign, thereby effectively scraping the dust. The device has a significant cleaning effect on dust and saves manpower.

[0004] In practice, the warning sign is fixedly connected to a pair of support rods. The warning sign and the support rods cannot be folded for storage, which is inconvenient. Also, the warning sign and the support frame cannot be disassembled and replaced. When the warning sign is used for a long time or is damaged, it is not convenient to replace it, which affects normal use. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-6 A construction safety warning device includes a frame 1, a support frame 2 and a display board 3. The support frame 2 is rotatably connected to the side of the frame 1. The frame 1 and the support frame 2 are fixed and folded for storage by a support component 4.

[0026] The display panel 3 is located in the middle of the frame 1. The display panel 3 and the frame 1 are connected by a positioning structure 5 for double-sided display. The display panel 3 is also detachably connected to the frame 1 by the positioning structure 5.

[0027] It should be added that display board 3 is a handwriting board, which can be used to write warning slogans with chalk or watercolor pens to serve as a warning to staff. In particular, display board 3 is a double-sided display board, that is, both sides can be used for writing. The positioning structure 5 enables double-sided use, reducing the time for secondary writing and avoiding affecting normal use.

[0028] Furthermore, the support assembly 4 includes a fixing frame 41, the support frame 2 is composed of a pair of support rods 21, the top of the pair of support rods 21 has a clearance space, and a reinforcing rod is fixedly connected to the bottom of the pair of support rods 21, and a receiving groove 22 is provided on the side of the bottom.

[0029] The fixing frame 41 has a U-shaped structure. One end of the fixing frame 41 is rotatably connected to the frame 1 with an opening, and the other end is slidably connected to the receiving groove 22 away from the opening.

[0030] Furthermore, the fixing frame 41 has a positioning glass bead 42 embedded on the side away from the opening end. The bottom of the support rod 21 is provided with a pair of through holes 43 that communicate with the receiving groove 22. The telescopic column end of the positioning glass bead 42 engages with the through hole 43.

[0031] In this embodiment, the telescopic column end of the positioning glass bead 42 engages with the through hole 43 at the bottom to fix the support frame 2 by means of support. At this time, the support frame 2 and the frame 1 are supported in a V-shaped structure.

[0032] Similarly, when the telescopic column end of the positioning glass bead 42 engages with the through hole 43 at the top, the fixing frame 41 is located in the receiving groove 22, which can fold the support frame 2 for easy storage. In addition, a handle is fixedly connected to the top of the frame 1.

[0033] It is worth mentioning that the top of the pair of support rods 21 is provided with clearance space, which, along with the opening end of the fixing frame 41, is used to prevent the display panel 3 from flipping.

[0034] More specifically, the frame 1 is laterally rotatably connected to a connecting rod 6 in the middle, the display panel 3 is inserted through the connecting rod 6 through a through hole, and both the display panel 3 and the frame 1 are provided with guide grooves 31 connecting the two sides on the inner wall of the through hole. The outer wall of the connecting rod 6 is fixed with a limit pin 61, and the limit pin 61 is movably inserted into the guide groove 31.

[0035] It should be added that the purpose of the guide groove 31 provided on the inner wall of the through hole of the display panel 3 is that the limiting pin 61 is slidably connected in the guide groove 31, and the display panel 3 can be rotated synchronously by rotating the connecting rod 6 through the limiting pin 61.

[0036] Furthermore, the purpose of providing a guide groove 31 on the inner wall of the through hole in the frame 1 is to avoid the limiting pin 61 and prevent the limiting pin 61 from contacting the frame 1 when the connecting rod 6 is removed.

[0037] In general, the positioning structure 5 includes a positioning seat 51. The positioning seat 51 is movably inserted into both sides of the frame 1 through a pair of positioning posts 52. The midpoint of the positioning seat 51 is rotatably connected to the connecting rod 6, and positioning grooves 53 are also provided on both sides of the connecting rod 6.

[0038] Furthermore, it also includes a positioning piece 54. One end of the connecting rod 6 is fixedly connected to the stop block, and the other end is slidably connected to the positioning piece 54. The positioning piece 54 has a pair of protrusions 541 on its periphery, and a deformation groove 542 is provided at the protrusions 541. The protrusions 541 abut against and slide with the positioning groove 53 through the deformation groove 542.

[0039] In this embodiment, the positioning piece 54 is preferably made of a deformable material such as silicone or plastic. The opening direction of the positioning groove 53 corresponds to the vertical direction of the frame 1 and the display panel 3, ensuring that the display panel 3 and the frame 1 are aligned when the positioning piece 54 is positioned.

[0040] Specifically, the protrusion 541 is engaged in the positioning groove 53 to fix the connecting rod 6 and the display panel 3. When the unlocking handwheel rotates the connecting rod 6 to drive the display panel 3 to rotate, the protrusion 541 abuts against and slides with the positioning groove 53 through the deformation groove 542. When the protrusion 541 rotates half a circle and engages with another positioning groove 53, the display panel 3 can be changed.

[0041] Furthermore, the positioning plate 54 can be disassembled by unlocking the handwheel, the positioning seat 51 that has lost its fixing resistance can be removed and replaced, the connecting rod 6 can be taken out along one side of the stop block, and the display panel 3 can be disassembled. Also, the stop block abuts against the frame 1, and the positioning plate 54 rotates in a half-circle when it rotates.

[0042] Finally, a handwheel is threadedly connected to one end of the connecting rod 6, and the handwheel abuts against the slidable positioning piece 54.

[0043] Working method: During operation, after pressing the telescopic column end of the positioning glass bead 42 to retract and disengage from the through hole 43, the fixing frame 41 slides along the receiving groove 22, and the telescopic column end of the positioning glass bead 42 engages with the bottom through hole 43 to fix the support frame 2.

[0044] Warning signs were written on both the inner and outer sides of display board 3 to serve as a warning to staff.

[0045] While the display board 3 is flipped by rotating the connecting rod 6 with the handwheel, the connecting rod 6 drives the positioning piece 54 to rotate synchronously through the limiting groove 62. At this time, the protrusion 541 abuts against and slides with the positioning groove 53 through the deformation groove 542. After the positioning piece 54 rotates half a circle to reset, the protrusion 541 engages with the positioning groove 53 again, so that the display board 3 can be repositioned.

[0046] Finally, after removing the handwheel, taking out the positioning piece 54 and the positioning seat 51, the connecting rod 6 is removed along one side of the stop block, and the display panel 3 can be disassembled.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
