Description

Technical Field

[0001] This utility model relates to the field of road infrastructure technology, specifically to an anti-loosening ground nail. Background Technology

[0002] In-ground road spikes are tools used to fix roads to the ground to assist traffic safety. Also known as in-ground road studs, they are installed on the road surface in conjunction with road markings and come in both active and passive luminous types. At night or in rainy weather, luminous road studs at intersections can remind drivers and pedestrians to pay attention to traffic safety; road studs on road markings can guide vehicles to travel in their lanes, ensuring driving safety.

[0003] Literature review revealed that an existing patent (publication number: CN221822775U) discloses an anti-loosening buried ground spike, including a spike shell and a transparent protective spike cover. The spike shell is equipped with a miniature solar panel and a light tube inside. The spike shell is covered with a buried mounting shell. The spike shell and the transparent protective spike cover are fixed together by fixing screws. The surface of the spike shell is provided with a locking component. The inside of the buried mounting shell is provided with a locking hole corresponding to the locking component. One end of the locking component is connected to an auxiliary disassembly component.

[0004] While the aforementioned existing technology facilitates nail shell disassembly to some extent, in actual operation, it requires using a hooked tool to hook the disassembly rings. If the spring mechanism disengages, the locking blocks will reset, requiring the operator to simultaneously hook all four disassembly rings and pull them up. This process is inconvenient, slow, cumbersome, and impractical. Therefore, we propose an anti-loosening ground nail to address these issues. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides an anti-loosening ground nail to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-loosening ground nail, comprising an underground mounting shell, a nail shell inside the underground mounting shell, an annular groove inside the nail shell, four rotating shafts rotatably connected inside the annular groove, and a locking block fixedly fitted on the surface of each of the four rotating shafts, a movable groove on the surface of the nail shell, the locking block located inside the movable groove, a rotating ring slidably connected inside the annular groove, a locking tooth fixedly connected to the surface of the rotating ring, a first tooth groove on the surface of the locking block near the rotating ring, the first tooth groove and the locking tooth meshing with each other, a locking groove on the inner wall of the underground mounting shell, the locking groove and the locking block being adapted to each other, and a driving component inside the annular groove.

[0007] By adopting the above technical solution, the number of operating steps for staff is greatly reduced, the difficulty of operation is lowered, and the efficiency of staff in disassembling and assembling nail shells is further improved. It is highly practical and very easy to operate.

[0008] Preferably, the drive assembly includes a connecting rod rotatably connected inside an annular groove. A drive gear is fixedly sleeved on the surface of the connecting rod. A second toothed groove is formed on the surface of the rotating ring, and the second toothed groove meshes with the teeth on the surface of the drive gear. A circular groove is formed inside the connecting rod, and a screw is disposed inside the circular groove. A synchronization groove is formed on the inner wall of the circular groove. A synchronization block is fixedly connected to the surface of the screw and slidably connected inside the synchronization groove. The upper end of the screw is threaded through the interior of the screw housing.

[0009] By adopting the above technical solution, the connecting rod can be rotated synchronously when the screw is rotated, and the stability of the locking block can be guaranteed by the self-locking of the screw, thereby improving the efficiency of disassembling and assembling the nail shell.

[0010] Preferably, the upper surface of the screw has a cross-shaped groove.

[0011] Preferably, the upper surface of the nail shell is provided with a transparent protective nail cover, which is fixedly installed on the upper side of the nail shell by screws.

[0012] Compared with the prior art, this utility model provides an anti-loosening ground nail, which has the following beneficial effects:

[0013] 1. This anti-loosening ground nail can be driven by the operation of the drive component to rotate the rotating ring, thereby causing the four locking blocks to rotate synchronously around the rotating shaft. This allows the locking blocks to move inside the movable slot, ultimately enabling all four locking blocks to simultaneously engage or disengage from the slot. This greatly reduces the number of steps required by the operator, lowers the difficulty of operation, and improves the efficiency of the operator in disassembling and assembling the nail shell. It is highly practical and very easy to operate.

[0014] 2. This anti-loosening ground nail, through the setting of the synchronizing block and synchronizing groove, can drive the connecting rod to rotate synchronously when the screw is rotated, and the stability of the locking block can be guaranteed by the self-locking of the screw, thereby improving the efficiency of disassembling and assembling the nail shell.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-6This utility model provides a technical solution: an anti-loosening ground nail, including an underground installation shell 1, with a nail shell 2 inside the underground installation shell 1. The nail shell 2 has an annular groove 3 inside for restricting the movement trajectory of the structure. Four rotating shafts 4 for supporting are rotatably connected inside the annular groove 3. Each of the four rotating shafts 4 has a locking block 5 for fixing the nail shell 2. The nail shell 2 has a movable groove 6 on its surface. The locking block 5 is located inside the movable groove 6. A rotating ring 7 for connecting is slidably connected inside the annular groove 3. The rotating ring 7 has a locking tooth 8 for transmission fixedly connected to its surface. The rotation of the rotating ring 7 can drive the locking tooth 8 on its surface to move synchronously. The side of the locking block 5 near the rotating ring 7 has a first tooth groove 9. The first tooth groove 9 and the locking tooth 8 are engaged. Because the locking tooth 8 and the first tooth groove 9 are engaged with each other, the rotation of the rotating ring 7 will drive the locking block 5 to rotate around the rotating shaft 4.

[0027] The inner wall of the buried mounting housing 1 is provided with a slot 10 for fixing the nail housing 2. The slot 10 and the locking block 5 are compatible. The annular groove 3 is provided with a drive component for rotating the rotating ring 7. By operating the drive component, the rotating ring 7 can be rotated, thereby driving the four locking blocks 5 to rotate synchronously around the rotating shaft 4. This allows the locking blocks 5 to move inside the movable groove 6, ultimately enabling the four locking blocks 5 to simultaneously engage or disengage from the slot 10. This greatly reduces the number of steps for operators, lowers the difficulty of operation, and improves the efficiency of operators in assembling and disassembling the nail housing 2. It is highly practical and very easy to operate.

[0028] The drive assembly includes a connecting rod 11, which is rotatably connected inside the annular groove 3. A drive gear 12, which plays a transmission role, is fixedly sleeved on the surface of the connecting rod 11. A second tooth groove 13, which plays a transmission role, is opened on the surface of the rotating ring 7. The second tooth groove 13 and the teeth on the surface of the drive gear 12 are meshed and connected. The rotation of the connecting rod 11 can drive the rotation of the drive gear 12. Since the drive gear 12 and the second tooth groove 13 are engaged, the rotation of the drive gear 12 will drive the rotating ring 7 to rotate.

[0029] The connecting rod 11 has a circular groove 1101 inside, and a screw 14 for transmission is set inside the circular groove 1101. The inner wall of the circular groove 1101 has a synchronization groove 1102 for guiding and restricting the movement trajectory of the structure. A synchronization block 1401 for rotating the connecting rod 11 is fixedly connected to the surface of the screw 14. The synchronization block 1401 is slidably connected inside the synchronization groove 1102. Because the synchronization block 1401 on the surface of the screw 14 is slidably connected inside the synchronization groove 1102, the connecting rod 11 will be rotated when the screw 14 rotates, and the screw 14 will slide inside the connecting rod 11. The upper end of the screw 14 is threaded through the inside of the nail shell 2. The arrangement of the synchronization block 1401 and the synchronization groove 1102 enables the connecting rod 11 to rotate synchronously when the screw 14 is rotated. The self-locking of the screw 14 can ensure the stability of the locking block 5, thereby improving the efficiency of disassembling and assembling the nail shell 2.

[0030] The upper surface of the screw 14 is provided with a cross groove 15 to facilitate the operator to drive the screw 14 to rotate. By using the end of a Phillips screwdriver to engage with the cross groove 15 and then rotating the screwdriver, the screw 14 can be driven to rotate.

[0031] A transparent protective nail cover 16 is provided on the upper surface of the nail shell 2. The transparent protective nail cover 16 is fixedly installed on the upper side of the nail shell 2 by screws.

[0032] Working principle:

[0033] When using this anti-loosening ground nail, first, a hole is made in the road, special glue is applied to the hole, and the buried mounting shell 1 is fixed inside the hole. Then, the nail shell 2 is inserted into the buried mounting shell 1. When the worker needs to install the nail shell 2, the end of the Phillips screwdriver is engaged with the Phillips groove 15, and then the screwdriver is rotated. At this time, the rotation of the screwdriver will drive the rotation of the screw rod 14. Since the synchronizing block 1401 on the surface of the screw rod 14 is slidably connected to the inside of the synchronizing groove 1102, the rotation of the screw rod 14 will drive the connecting rod 11 to rotate, and the screw rod 14 will slide inside the connecting rod 11.

[0034] Then, the rotation of the connecting rod 11 can drive the rotation of the drive gear 12. Since the drive gear 12 and the second tooth groove 13 are engaged, the rotation of the drive gear 12 will drive the rotating ring 7 to rotate.

[0035] The rotation of the rotating ring 7 can drive the locking teeth 8 on its surface to move synchronously. Since the locking teeth 8 and the first tooth groove 9 are engaged with each other, the rotation of the rotating ring 7 will drive the locking block 5 to rotate around the rotating shaft 4, thereby causing the locking block 5 to be locked into the inside of the locking groove 10.

[0036] During installation, the screw 14 is rotated and moved downwards, and the locking block 5 rotates and locks into the slot 10, thereby realizing the installation of the nail shell 2;

[0037] During disassembly, when the screw 14 rotates and moves upward, the locking block 5 will rotate and disengage from the locking groove 10, causing the locking block 5 to rotate into the interior of the movable groove 6, thereby enabling the disassembly of the nail shell 2.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
