Description

Technical Field

[0001] This utility model relates to the technical field of license plate fastening devices, specifically to a license plate fastening device with anti-detachment function. Background Technology

[0002] In the current transportation sector, license plates serve as crucial vehicle identifiers, and their secure installation is paramount. However, existing license plate securing devices present numerous problems.

[0003] Traditional license plate fastening devices have a relatively simple structure, mostly using ordinary bolts and nuts for fixation. During vehicle operation, factors such as road bumps and vibrations can easily cause the bolts to rotate and the nuts to gradually loosen, leading to a loose license plate or even detachment. Once a license plate falls off, it not only affects the normal driving of the vehicle but may also cause traffic violations, resulting in trouble and losses for the vehicle owner. Furthermore, some fastening devices lack effective anti-loosening and limiting structures, making them unsuitable for complex road conditions and harsh environments. When traversing potholes, driving at high speeds, or encountering strong winds, the license plate's shaking amplitude increases, further exacerbating the risk of the fastening device loosening. Utility Model Content

[0004] To address the shortcomings of existing technologies, the technical solution adopted by this utility model is as follows: a license plate fixing device with anti-detachment function, comprising: a bolt, a locking component slidably connected to the outer wall of the bolt, a fixing component provided at the end of the bolt away from the locking component, and anti-slip rings fixedly connected to the outer walls of both the locking component and the fixing component; the locking component includes an upper pressure cover, a limit strip fixedly connected to the inner wall of the upper pressure cover, a latching cover slidably connected to the inner wall of the upper pressure cover, a limit groove formed on the outer wall of the latching cover, and a latching block fixedly connected to the inner wall of the latching cover.

[0005] Preferably, the inner wall of the upper pressure cover is slidably connected to the outer wall of the bolt, and the outer wall of the upper pressure cover is fixedly connected to the outer wall of the anti-slip ring.

[0006] Preferably, the outer wall of the limiting strip is slidably connected to the inner wall of the limiting groove, and the outer wall of the locking block is slidably connected to the inner wall of the bolt. The limiting strips are arranged in a ring along the central axis of the upper cover, and the limiting grooves are opened in a ring along the central axis of the locking cover. By aligning the slots on the locking block and the bolt, the locking cover is pressed into the upper cover, causing the locking block to engage with the slot on the bolt and, through the limiting strips, engage with the limiting groove. The locking cover cannot rotate, thus locking the bolt and preventing rotation.

[0007] Preferably, the fixing assembly includes a lower pressure cover, a lower ratchet ring slidably connected to the inner wall of the lower pressure cover, a push spring fixedly connected to the bottom end of the lower ratchet ring, a toggle block fixedly connected to the outer wall of the lower ratchet ring, and a nut disposed inside the lower pressure cover, with an upper ratchet ring fixedly connected to the bottom end of the nut. When the upper and lower ratchet rings engage, the lower ratchet ring remains in contact with the upper ratchet ring under the action of the push spring, forming a one-way locking structure. When the bolt is no longer rotated, the lower ratchet ring locks the upper ratchet ring, preventing the nut from reversing and loosening.

[0008] Preferably, the inner wall of the lower pressure cap is slidably connected to the outer wall of the bolt, the inner wall of the nut is threadedly connected to the outer wall of the bolt, the outer wall of the upper ratchet ring is slidably connected to the outer wall of the lower ratchet ring, and the outer wall of the lower pressure cap is fixedly connected to the outer wall of the anti-slip ring. When it is necessary to remove the nut, the actuating block is pulled through the external slot, causing the lower ratchet ring to move and disengage from the upper ratchet ring, allowing the nut to rotate in the opposite direction.

[0009] Preferably, the inner wall of the lower pressure cover has a slot, a snap-on cover is slidably connected to the inner wall of the lower pressure cover, and a rubber ring is fixedly connected to the outer wall of the snap-on cover. The outer wall of the rubber ring is slidably connected to the inner wall of the slot. The snap-on cover is installed into the lower pressure cover, so that the rubber ring is engaged in the slot, thereby preventing the snap-on cover from detaching from the lower pressure cover and further protecting the internal structure.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. This utility model achieves dual anti-detachment protection by setting a locking component and a fixing component to work together. The locking component has a locking block that engages with the bolt slot and a limiting structure to prevent the cover from rotating, effectively locking the bolt and preventing it from rotating and loosening due to vehicle vibration. The fixing component uses a one-way locking structure formed by the upper and lower ratchet rings to prevent the nut from turning back and loosening, ensuring that the license plate is installed firmly and greatly reducing the risk of the license plate falling off during driving.

[0012] 2. The installation process of this utility model is simple and easy to understand. Installation can be completed by pressing the nut and turning the bolt. Disassembly is simple; just pull the lever to disengage the lower ratchet ring from the upper ratchet ring, and the nut can be easily turned in the opposite direction, which is convenient and quick. At the same time, the design of the snap-on cover not only protects the internal structure, but also makes the installation method very simple. The cooperation between the snap-on cover and the rubber ring not only provides anti-slip function, but also effectively seals the interior, preventing dust, rainwater and other impurities from entering the internal structure.

[0020] Please see Figure 1 - Figure 4 This utility model provides a technical solution: a license plate fixing device with anti-detachment function, comprising: a bolt 1, a locking component 3 slidably connected to the outer wall of the bolt 1, a fixing component 4 provided at the end of the bolt 1 away from the locking component 3, and anti-slip rings 2 fixedly connected to the outer walls of both the locking component 3 and the fixing component 4; the locking component 3 includes an upper pressure cover 31, a limit strip 32 fixedly connected to the inner wall of the upper pressure cover 31, a card cover 33 slidably connected to the inner wall of the upper pressure cover 31, a limit groove 35 opened on the outer wall of the card cover 33, and a card block 34 fixedly connected to the inner wall of the card cover 33.

[0021] The inner wall of the upper pressure cover 31 is slidably connected to the outer wall of the bolt 1, and the outer wall of the upper pressure cover 31 is fixedly connected to the outer wall of the anti-slip ring 2.

[0022] The outer wall of the limiting strip 32 is slidably connected to the inner wall of the limiting groove 35, the outer wall of the locking block 34 is slidably connected to the inner wall of the bolt 1, the limiting strip 32 is arranged in a ring along the central axis of the upper pressure cover 31, and the limiting groove 35 is opened in a ring along the central axis of the locking cover 33.

[0023] The fixing component 4 includes a lower pressure cover 41, a lower ratchet ring 47 slidably connected to the inner wall of the lower pressure cover 41, a push spring 48 fixedly connected to the bottom end of the lower ratchet ring 47, a toggle block 49 fixedly connected to the outer wall of the lower ratchet ring 47, a nut 42 provided inside the lower pressure cover 41, and an upper ratchet ring 45 fixedly connected to the bottom end of the nut 42.

[0024] The inner wall of the lower pressure cap 41 is slidably connected to the outer wall of the bolt 1, the inner wall of the nut 42 is threadedly connected to the outer wall of the bolt 1, the outer wall of the upper ratchet ring 45 is slidably connected to the outer wall of the lower ratchet ring 47, and the outer wall of the lower pressure cap 41 is fixedly connected to the outer wall of the anti-slip ring 2.

[0025] The inner wall of the lower pressure cover 41 is provided with a slot 46, and a buckle cover 43 is slidably connected to the inner wall of the lower pressure cover 41. A rubber ring 44 is fixedly connected to the outer wall of the buckle cover 43, and the outer wall of the rubber ring 44 is slidably connected to the inner wall of the slot 46.

[0026] Working principle:

[0027] In use, the locking component 3 is located outside the license plate, and the fixing component 4 is located inside the license plate. Bolt 1 passes through the upper pressure cover 31, the license plate mounting hole, and the lower pressure cover 41. When the nut 42 is held down and bolt 1 is turned, the upper and lower pressure covers 31 and 41 remain in contact with the license plate and will not move, causing the nut 42 to move. The nut 42 then moves the upper ratchet ring 45 into the lower pressure cover 41. The upper ratchet ring 45 engages with the lower ratchet ring 47, which, under the action of the push spring 48, remains in contact with the upper ratchet ring 45, forming a one-way locking structure. When bolt 1 is no longer turned, the lower ratchet ring 47 locks the upper ratchet ring 45, preventing the nut 42 from reversing and loosening. When it is necessary to remove the nut 42... By pulling the actuating block 49 through the external slot, the lower ratchet ring 47 moves, disengaging from the upper ratchet ring 45, allowing the nut 42 to rotate in the opposite direction. The cover 43 is then installed into the lower cover 41, causing the rubber ring 44 to engage in the slot 46, preventing the cover 43 from detaching from the lower cover 41 and further protecting the internal structure. After the bolt 1 and nut 42 are connected, the cover 33 is pressed into the upper cover 31 by aligning the slot on the bolt 1 with the locking block 34, causing the locking block 34 to engage in the slot on the bolt 1 and engage in the limiting groove 35 via the limiting strip 32. The cover 33 cannot rotate, thus locking the bolt 1 and preventing rotation. Simultaneously, anti-slip rings 2 are fixedly connected to the outer walls of both the upper cover 31 and the lower cover 41, increasing friction with the license plate surface and preventing the upper cover 31 and lower cover 41 from loosening due to vibration during vehicle rotation.

[0028] The entire device, through the coordinated work of its components, effectively enhances the stability of license plate installation and has a good anti-detachment function.
