Description

Technical Field

[0001] This utility model belongs to the technical field of road stud structure for road administration, and specifically refers to a road stud. Background Technology

[0002] Road studs, also known as raised pavement markers, are a widely used traffic safety device. They are mainly installed in the middle of road markings, between double yellow lines, on scenic pavements, and at tunnel entrances—places requiring warning—to alert drivers and pedestrians through retroreflective properties or active flashing lights. The most common type of road stud is the reflective road stud, which incorporates reflective elements to remind drivers to drive safely. These studs are simple in structure, low in production cost, and readily achieve high compressive strength, making them the most widely used type of road stud. During installation, adhesive is typically applied to the road surface or the base of the stud. This adhesive requires time to dry and secure. If a vehicle passes over the stud before the adhesive is fully dry, the stud may be disturbed, causing it to shift or detach.

[0003] For example, Chinese patent CN202420987553.X describes a conveniently installed road spike, comprising a fastener, a spike body, and a connecting rod. The fastener has external threads, and the spike body has an installation hole through which the fastener passes. The spike body also has an abutment portion that communicates with the installation hole and abuts against the head of the fastener. One end of the connecting rod has internal threads, and the connecting rod is fixed to the bottom of the spike body by the engagement of the internal and external threads. This product provides a disassembly method, but it has certain drawbacks: the connecting rod still needs to be fixed to the ground with cement, and workers still need to wait for the cement to dry before installation. While installation is convenient, the waiting time is long (at least 4 hours after the cement fixing the spike has cured before the installation barriers can be removed), resulting in a longer construction period. Summary of the Invention

[0004] The purpose of this invention is to provide a detachable track spike that has a short installation period and a stable structure.

[0005] The purpose of this utility model is achieved as follows:

[0006] A road spike includes a road spike body with an indicator bevel on the body; it also includes a ground spike, the road spike body being detachably connected to the ground spike by fasteners; the ground spike has a channel in the middle, into which a screw can enter, and a constriction or limiting part is provided at the end of the channel, the constriction or limiting part preventing the head of the screw from leaving the channel, and the threaded section of the screw can pass through the channel.

[0007] The lower end of the ground nail is connected to a claw by a screw thread. The lower end side wall of the ground nail is provided with an inclined surface. The claw part can abut against the inclined surface. When the screw is turned and the claw is brought close to the ground nail, the claw part deforms along the inclined surface.

[0008] Furthermore, the periphery of the ground nail is provided with several longitudinal ribs, which are located between the claw portions of the clamping claw, and the clamping claw moves along the longitudinal ribs.

[0009] Furthermore, the claw has a skirt in the middle, and the middle of the skirt has a threaded section that mates with the screw; at least one complete threaded ring is provided on the inner side of the skirt; both the claw and the ground nail are metal parts.

[0010] Furthermore, the longitudinal ribs protrude from the surface of the ground spike; and the closer the longitudinal ribs are to the side connecting to the ground spike body, the more the longitudinal ribs protrude outwards.

[0011] Furthermore, the channel of the ground spike is provided with internal threads, and the fastener is a screw, which passes through the through hole in the middle of the ground spike body and is fixed on the internal threads of the channel.

[0012] Furthermore, a positioning block is embedded in the main body of the track spike and the central through hole, and the positioning block also has a through hole in the center for the screw to pass through.

[0013] Furthermore, when the main body of the road spike is connected to the ground spike, the positioning block and the upper surface of the road spike make face-to-face contact.

[0014] Furthermore, the positioning block is provided with at least one protrusion, and the ground nail is provided with a recess that mates with the protrusion; or, the positioning block is provided with at least one recess, and the ground nail is provided with a protrusion that mates with the recess.

[0015] Furthermore, the central hole of the rail spike body is a countersunk hole, which conceals the head of the screw; the positioning component is a metal component, and the rail spike body is a plastic component.

[0016] Furthermore, the cross-section of the ground nail is square or irregular.

[0017] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0018] 1. This utility model uses an independent road stud with a locking claw. The user can rotate the screw to deform the claw laterally. During construction, workers drill holes of a specified size in the road surface, insert the road stud into the hole, and then rotate the screw to allow the claw to hook onto the inner wall of the hole. Finally, the road stud body is installed on the stud. The entire installation process is quick, requiring no external glue or cement, effectively reducing the installation time. The main purpose of making the road stud body detachable is: a) If the road stud body is damaged, only the road stud body can be replaced, resulting in high replacement efficiency and eliminating the need for partial road closure construction; b) Road studs are generally installed on road markings, which need to be repainted periodically. Workers can remove the road stud body, cover the hole with masking tape, paint the lines, and then reinstall the road stud body.

[0019] 2. The ground spike of this utility model has several longitudinal ribs on its periphery. These longitudinal ribs not only provide guidance for the claws of the clamping claws, but also protrude from the outer surface of the ground spike. They can abut against the holes in the road surface through the longitudinal ribs, allowing the ground spike to be stably placed in the holes. Preferably, the longitudinal ribs protrude more outward as they are closer to the side connecting to the ground spike body. Through this structure, as the ground spike is driven into the hole in the road surface, the longitudinal ribs gradually abut against the hole.

[0020] 3. When the road stud body and the ground nail of this utility model are connected, the positioning block and the upper surface of the road stud abut face to face. Furthermore, the positioning block has at least one protrusion, and the ground nail has a recess that mates with the protrusion. Through the cooperation of the protrusion and the recess, the installation direction of the road stud body is determined, ensuring a more accurate position and preventing deviation after installation. In other words, the installation direction of the road stud body can be controlled by the ground nail, and workers only need to fix the road stud according to regulations. After the road stud body is replaced or disassembled, it can maintain its original orientation. Attached Figure Description

Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Figure 1-10 As shown:

[0034] A road stud includes a road stud body 1 with an indicator bevel 11 for fixing reflectors, reflective beads, LED lights, reflective films, etc. It also includes a ground spike 2. The road stud body 1 is detachably connected to the ground spike 2 via fasteners. Various connection methods can be used between the road stud body 1 and the ground spike 2, such as a snap-fit ​​connection (with a male snap on the road stud body and a female snap on the ground spike), or a screw fixing method as described below, as long as both are detachably connected. The ground spike 2 has a channel 20 in its middle, into which a screw 9 can enter. The end of the channel has a constriction 28 or a limiting part, which prevents the screw head from disengaging from the channel while allowing the screw thread to pass through. The limiting part can be a component fixed to the end of the channel, preventing the screw head from disengaging. After the ground spike 2 is driven into the ground, the user can adjust the screw 9 built into the channel through the built-in channel 20, making the screw 9 less prone to damage. The lower end of the ground nail 2 is threadedly connected to a claw 3 by a screw 9. The lower end side wall of the ground nail 2 is provided with an inclined surface 21. The claw part 31 of the claw can abut against the inclined surface 21. When the screw 9 is rotated and the claw 3 is brought close to the ground nail 2, the claw part 31 deforms along the inclined surface 21.

[0035] The ground stake 2 has several longitudinal ribs 22 arranged around its periphery. These ribs are located between the claw portions 31 of the clamping claw 3, which moves along the longitudinal ribs 22. The longitudinal ribs limit the movement of the claw portions, causing them to conform to a regular outward curve along the inclined surface, which helps the claw portions better hook onto the inner surface of the hole in the ground. Furthermore, the longitudinal ribs 22 protrude beyond the surface of the ground stake 2; and the closer the longitudinal ribs are to the side connecting to the ground stake body, the more they protrude outwards. Figure 5 and Figure 6 As shown, the width of the longitudinal ribs increases from bottom to top, meaning that the longitudinal ribs become increasingly tighter as the ground nail is driven into the hole. This structure allows the ground nail to be better positioned in the hole in the ground.

[0036] The claw 3 has a skirt 32 at its center, and the skirt 32 has a threaded section 39 for engaging with the screw. At least one complete threaded ring is provided on the inner side of the skirt 32. This structure of the skirt and at least one threaded ring increases the contact area between the claw and the screw, resulting in a tighter threaded connection, reducing the likelihood of loosening or lateral deformation, and facilitating orderly movement of the claw by the screw. Preferably, both the claw 3 and the ground stake 2 are metal components, as metal components have high strength, which is beneficial for long-term outdoor use.

[0037] The channel of the ground spike 2 is provided with an internal thread, namely the ground spike thread section 29, and the fastener is a screw 9. The screw 9 passes through the through hole in the middle of the ground spike body and is fixed on the ground spike thread section 29 of the channel.

[0038] A positioning block 12 is embedded in the center of the road spike body 1, where a through hole is located. The positioning block 12 also has a through hole in the center for screws to pass through. The purpose of setting the positioning block is: a) When the road spike body and the ground spike are connected, the upper surfaces of the positioning block and the road spike abut face to face. The road spike body is made of plastic, while the positioning block is made of metal and is not easily deformed. Therefore, using the positioning block as a positioning standard makes the connection between the road spike body and the ground spike more flat. b) The positioning block 12 is provided with at least one protrusion 121, and the ground spike 2 is provided with a recess 23 that mates with the protrusion 121; or, the positioning block is provided with at least one recess, and the ground spike is provided with a protrusion that mates with the recess. Through the cooperation of the protrusion and the recess, the user can install with direction and determine the installation direction of the road spike body, making the position of the road spike body more accurate and preventing deviation when the installation is completed. That is, the installation direction of the road spike body can be controlled by the ground spike. Workers only need to fix the road spike according to the regulations. After the road spike body is replaced or disassembled, the road spike body can maintain its original direction.

[0039] The central hole of the rail spike body 1 is a countersunk hole 10, and the conical surface 101 of the countersunk hole hides the head of the screw.

[0040] The cross-section of the ground nail 2 is square or irregular.

[0041] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
