[0003] Although the above technology achieves a certain degree of anti-theft effect when used, there is a certain gap between the two due to the snap-on connection, which causes the sign to be not tightly installed. As a result, rainwater and dust from the outside can easily enter this gap and cause blockage and damage to the components. Therefore, in order to solve the above technical defects, we have proposed a dust-proof motor vehicle sign. Utility Model Content

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0024] Example 1
[0025] Reference Figures 1-6 A dust-proof motor vehicle sign comprises a sign body 1 and a mounting ring 2 with an H-shaped cross-section arranged on the back side of the sign body 1. A locking rod 3 is slidably inserted in the middle of the mounting ring 2. One end of the locking rod 3 is connected to the middle of the sign body 1, and the other end of the locking rod 3 extends to the end of the mounting ring 2 away from the sign body 1 and is threadedly installed with a locking cap 4. A mounting groove is provided between the back side of the sign body 1 and the mounting ring 2, and a sealing ring 5 is provided in the mounting groove. An annular airbag 6 is provided on the back side of the sign body 1 and on the outside of the sealing ring 5.
[0026] Example 2
[0027] Reference Figures 1-6In other parts are the same as example 1, the embodiment is different from example 1 in that:
[0028] The middle part of the mounting ring 2 is provided with a pressing surface 7 on both sides, and the back side of the sign body 1 is provided with a corresponding annular contact part 8 in the middle part. The pressing surface 7 and the annular contact part 8 are jointly provided with a receiving groove, and the receiving groove is provided with a sealing ring 9. The end of the locking cap 4 facing the sign body 1 is provided with a corresponding inclined contact surface corresponding to the pressing surface 7. The pressing surface 7 and the inclined contact surface are smooth surfaces. The setting of the pressing surface 7 facilitates the close contact between the annular contact part 8 of the sign body 1 and the locking cap 4 and the mounting ring 2 when the locking cap 4 is rotated and locked, thereby effectively preventing rain and dust from entering the gap between the two, i.e. effectively preventing rain and dust from causing erosion and damage to the subsequent locking cap 4, thereby ensuring that the sign is more stable and long-lasting during subsequent use. At the same time, the setting of the sealing ring 9 further improves the sealing between the sign body 1 and the mounting ring 2, i.e. further prevents the erosion of external rain and dust.
[0029] The outer ring surface of the locking rod 3 in the middle part is provided with a plurality of limiting strips 10, and the middle part of the mounting ring 2 is provided with a corresponding limiting groove corresponding to the limiting strips 10. The setting of the limiting strips 10 makes the locking rod 3 unable to rotate after being inserted into the mounting ring 2, thereby not only ensuring the regularity of the position of the sign body 1 after installation, but also ensuring that the locking rod 3 does not rotate when the locking cap 4 is rotated, i.e. facilitating the disassembly and installation of the locking cap 3. The locking rod 3 is provided with a sealing pad 11 on the rod body between the limiting strips 10 and the locking cap 4. The end of the locking cap 4 away from the mounting ring 2 is hexagonal. The setting of the sealing pad 11 further improves the sealing between the sign body 1 and the mounting ring 2. The end of the locking cap 4 in hexagonal shape is provided with anti-skid lines on each side surface. The end of the locking cap 4 in hexagonal shape is provided with two force holes 12. The setting of the force holes 12 facilitates the disassembly and installation of the locking cap 4 by external hard rod bodies without wrench, thereby making it more convenient for personnel to disassemble the sign.
[0030] Principle and advantages of use: During use, the mounting ring 2 is mounted on the shell of an external motor vehicle. Then, when the sign needs to be installed, the person holding the sign inserts the locking rod 3 on the back of the sign into the mounting ring 2, that is, the threaded end of the locking rod 3 is inserted into the shell, and then the locking cap 4 is installed on the end of the locking rod 3 through the thread from the inside of the shell. At this time, under the action of the locking cap 4, the locking rod 3 cannot be separated from the mounting ring 2, that is, the sign is installed. At the same time, in this process, since there are air bags and air bags between the back of the sign body 1 and the shell and the mounting ring 2, respectively, The sealing ring 5, the sealing ring 9, the sealing gasket 11 between the locking cap 4 and the mounting ring 2, a total of four levels of sealing measures, prevent external rainwater and dust from entering between the sign body 1 and the mounting ring 2, that is, rainwater and dust cannot corrode the connection between the locking cap 4 and the locking rod 3, thereby avoiding the troublesome disassembly caused by the rust of the locking cap 4. That is, when using this solution, the installation and disassembly of the sign are relatively convenient, and by setting up sealing components, it provides dust and water proof effects to prevent dust and rainwater from corroding its internal components and causing damage to them and making them difficult to disassemble.
[0031] It should be further explained that the setting of the pressing surface 7 makes it convenient for the annular contact portion 8 of the sign body 1 and the locking cap 4 to fit tightly with the mounting ring 2 when the locking cap 4 is rotated and locked, thereby effectively preventing external rainwater and dust from entering the gap between the two, that is, effectively preventing rainwater, dust and sand from eroding and damaging the subsequent locking cap 4, thereby ensuring that the sign is relatively stable and long-lasting during subsequent use. At the same time, the setting of the sealing ring 9 further improves the sealing between the sign body 1 and the mounting ring 2, that is, further avoiding the erosion of external rainwater, dust and sand; the setting of the limit strip 10 makes the locking rod 3 unable to rotate after being inserted into the mounting ring 2, thereby not only ensuring the regular position of the sign body 1 after installation, but also ensuring that the locking rod 3 will not rotate when the locking cap 4 is rotated, which is convenient for disassembly and installation of the locking cap 3; the setting of the sealing gasket 11 further improves the sealing between the sign body 1 and the mounting ring 2.
[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
