Description

Technical Field

[0001] This utility model relates to the field of road sign technology, specifically to a transformable road sign. Background Technology

[0002] Existing convertible road signs typically store spare road signs in one area and use a clamping device to press them in place to prevent them from shifting, while display road signs extend out of the storage area for display. As a result, display road signs and spare road signs require more space, and the spare road signs cannot be automatically pressed in place, requiring a separate clamping device for pressing, which is quite cumbersome. Utility Model Content

[0003] The technical problem this invention aims to solve is that the device requires more space, and the spare road signs need to be tightened separately using a clamping device, which is quite cumbersome.

[0004] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a reversible road sign, including a pole, a crossbeam, a mounting shell, and several road sign bodies. The crossbeam is horizontally arranged on the top of the pole and the other end is connected to the mounting shell. The road sign body is arranged inside the mounting shell. The top of the mounting shell is through-connected, and the outer side of the bottom wall is provided with first telescopic rods. The power ends of the first telescopic rods are provided with a cover plate that can seal with the mounting shell. The road sign body is arranged between the cover plate and the mounting shell and is parallel to the surface of the mounting shell. The surface of the mounting shell away from the crossbeam is provided with a viewing window. The mounting shell is provided with a self-pressurizing component that facilitates the automatic adhesion of the road sign body. The cover plate is provided with a reversible component that can drive the road sign body to change position.

[0005] Furthermore, the conversion component includes a slide groove on the cover plate, a first electromagnet slidably disposed in the slide groove, a second telescopic rod disposed between the first electromagnet and the side wall of the slide groove, a magnetic strip on the road sign body that can be attracted to the first electromagnet, and a guide groove on the mounting shell that can guide the road sign body.

[0006] Furthermore, the bottom of the road sign body is provided with rollers that rotatably cooperate with the guide groove on both sides. The guide groove includes several vertical grooves on the side walls of the mounting shell. The top of the vertical grooves is provided with a first inclined groove. The other end of the first inclined groove is provided with a second inclined groove that is inclined in the same direction as the first inclined groove through a transition groove. The other end of the second inclined groove is provided with a vertically arranged transformation groove. The bottom end of the transformation groove is connected to the vertical groove through a connecting groove.

[0007] Furthermore, the self-pressurizing assembly includes a connecting groove that is inclined downwards along the direction away from the conversion groove, and the spacing between the conversion groove and the vertical groove, as well as between adjacent vertical grooves, is consistent with the thickness of the road sign body.

[0008] Furthermore, the mounting housing is equipped with a controller, which is electrically connected to the first electromagnet, the first telescopic rod, and the second telescopic rod.

[0009] The advantages of this utility model compared with the prior art are as follows:

[0010] 1. By positioning the road sign body between the cover plate and the mounting shell and parallel to the surface of the mounting shell, it is convenient to store all road sign bodies parallel inside the mounting shell, thereby reducing the space occupied by the road sign body. The setting of the viewing window facilitates the display of the road sign body near the viewing window.

[0011] 2. The self-pressurizing component allows each road sign to be automatically pressed together after the road sign body is rearranged, making it easier to leave display space for the road sign body that needs to be displayed.

[0012] 3. The coordinated design of the cover plate, the first telescopic rod, and the transformation component facilitates the adjustment of the road sign body's sequence as the cover plate rises and falls, thus enabling the transformation of the display. It also facilitates the sealing of the mounting shell by the cover plate, preventing external dust from contaminating the road sign body. Attached Figure Description

[0018] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] Combined with appendix Figure 1 Appendix Figure 2 and attached Figure 4 A reversible road sign includes a pole, a crossbeam 1, a mounting shell 2, and several road sign bodies 3. The crossbeam 1 is horizontally positioned at the top of the pole and connected at the other end to the mounting shell 2. The road sign bodies 3 are located inside the mounting shell 2. The top of the mounting shell 2 is through-hole, and the outer side of the bottom wall is provided with first telescopic rods 4. The power ends of the first telescopic rods 4 are connected by a cover plate 5 that can seal with the mounting shell 2. The road sign bodies 3 are located between the cover plate 5 and the mounting shell 2 and are parallel to the surface of the mounting shell 2. The surface of the mounting shell 2 away from the crossbeam 1 is provided with a viewing window 6. The cover plate 5 is provided with a reversible component 8 that can drive the road sign bodies 3 to change position.

[0020] The installation of the housing 2, cover plate 5, and road sign body 3 facilitates the sealed storage of the road sign body 3 inside the housing 2, preventing the road sign body 3 from being contaminated by dust, while the setting of the viewing window 6 facilitates the display of the road sign body 3 at the end.

[0021] Combined with appendix Figure 3 and attached Figure 4 The transformation component 8 includes a sliding groove 9 on the cover plate 5, a first electromagnet 10 slidably disposed in the sliding groove 9, a second telescopic rod 11 disposed between the first electromagnet 10 and the side wall of the sliding groove 9, a magnetic strip 12 disposed on the road sign body 3 that can be attracted to the first electromagnet 10, a guide groove 13 disposed on the mounting shell 2 that can guide the road sign body 3, and rollers 14 that cooperate with the guide groove 13 are respectively rotatably disposed on both sides of the bottom end of the road sign body 3; a controller 20 is disposed on the mounting shell 2, and the controller 20 is electrically connected to the first electromagnet 10, the first telescopic rod 4 and the second telescopic rod 11.

[0022] To facilitate the display transformation of the road sign body 3 in different locations, combined with the attached... Figure 3 The guide groove 13 includes several vertical grooves 15 on the side walls of the mounting shell 2. The top of the vertical grooves 15 is provided with a first inclined groove 16. The lower surface of the first inclined groove 16 is higher than the upper surface of the road sign body 3 inside the vertical groove 15. The other end of the first inclined groove 16 is provided with a second inclined groove 17 inclined in the same direction as the first inclined groove 16 through a reverse upward inclined transition groove. The other end of the second inclined groove 17 is provided with a vertically arranged transformation groove 18. The bottom end of the transformation groove 18 is connected to the vertical groove 15 through a connecting groove 19.

[0023] When it is necessary to change the road sign body 3:

[0024] First, the controller 20 drives the second telescopic rod 11 to the position of the road sign body 3 to be changed as needed. The second telescopic rod 11 drives the first electromagnet 10 to slide along the slide groove 9 to the top of the road sign body 3 to be changed.

[0025] Then, the first electromagnet 10 is energized. After the first electromagnet 10 is energized, it attracts the magnetic strip 12 on the corresponding road sign body 3. The outer wall of the road sign body 3 is smooth, which makes it easier to reduce friction and facilitate attraction.

[0026] Next, by activating the first telescopic rod 4, the cover plate 5 is raised. The cover plate 5 moves the road sign body 3 upward through the attraction of the first electromagnet 10 and the magnetic strip 12. The roller 14 moves from the vertical groove 15 to the first inclined groove 16 at the top. As the first telescopic rod 4 continues to drive, the road sign body 3 rises and slides along the horizontal direction of the first inclined groove 16 through the first electromagnet 10 until the roller 14 enters the transfer groove from the top of the first inclined groove 16. Since the transfer groove is set to be inclined upward in the opposite direction, the road sign body 3 rises through the roller 14 and slides along the horizontal direction of the transfer groove through the first electromagnet 10 until the roller 14 enters the intersection of the transfer groove and the second inclined groove 17. At this time, the first telescopic rod 4 cannot rise.

[0027] Finally, the first telescopic rod 4 drives the cover plate 5 to lower the road sign body 3. The road sign body 3 is then guided from the top of the second inclined groove 17 into the transformation groove 18 via the roller 14, making it convenient for the road sign body 3 to be displayed and viewed through the viewing window 6.

[0028] Combined with appendix Figure 3 and attached Figure 4 The mounting housing 2 is equipped with a self-pressurizing component 7 that facilitates the automatic adhesion of the road sign body 3. The self-pressurizing component 7 includes a connecting groove 19 that is inclined downward along the direction away from the transformation groove 18. The distance between the transformation groove 18 and the vertical groove 15 and between adjacent vertical grooves 15 is consistent with the thickness of the road sign body 3.

[0029] The connection slot 19 facilitates the movement of the remaining road signs away from the transformation slot 18 after one of the road sign bodies 3 is driven out of the vertical slot 15 by the first telescopic rod 4. This allows the remaining road sign bodies 3, except for the road sign body 3 to be transformed, to automatically approach and press together, thus freeing up the space at the transformation slot 18. This makes it easier for the road sign body 3 to be transformed to be guided into the transformation slot 18 to realize the transformation display of the road sign.
