Description

Technical Field

[0001] This utility model relates to the field of tactile paving technology, and in particular to an embossed one-piece molded tactile paving nail. Background Technology

[0002] Tactile paving studs are an indispensable key component of the tactile paving system. As an accessible facility specifically designed for visually impaired individuals, tactile paving aims to help blind people walk safely and independently on urban roads and in various public places. Tactile paving studs are raised and embedded or fixed to the surface of the tactile paving, providing tactile feedback to blind people about the direction, turns, and intersections of the road. This allows blind people to identify routes based on changes in the tactile sensation under their feet, thus successfully reaching their destination. It effectively ensures the safety of blind people traveling in outdoor environments, enhances their ability to participate in social life, promotes the construction of an accessible urban environment, and demonstrates society's care and inclusion of special groups.

[0003] Embossed one-piece molded tactile paving studs are an innovative manufacturing process and product form. They are mainly made of specific metals or high-strength composite materials using advanced one-piece molding technology. Their unique feature is that the anti-slip pattern on the surface of the tactile paving stud is not added later, but is formed simultaneously during the molding process. Compared with traditional assembled or post-processed tactile paving studs, these one-piece molded studs have the advantages of strong structural integrity and stable connection, effectively avoiding the problem of loosening or falling off parts due to long-term use. At the same time, the embossed one-piece molding process significantly improves the production efficiency of tactile paving studs and reduces production costs. They have high application value in large-scale tactile paving construction and can ensure that the tactile paving studs can stably perform their function of guiding blind people in various harsh environments.

[0004] Current embossed one-piece molded tactile paving studs have limitations in installation design. Their fixing methods are often relatively simple and cannot be well adapted to different types of ground surfaces, such as cement, asphalt, or brick. This can lead to installation difficulties and insecure fixing, affecting the overall stability and flatness of the tactile paving, causing inconvenience and even safety hazards for blind people. Existing technologies have developed various types of installation accessories to adapt to different ground surfaces. For cement surfaces, installation accessories with expansion bolts can be designed, and for asphalt surfaces, accessories with self-tapping screws and washers can be used to firmly fix the tactile paving studs to ground surfaces of different hardness and structures. However, in actual installation, it may be necessary to select appropriate accessories based on the specific ground conditions and the model of the tactile paving studs. This increases the complexity and cost of installation. Moreover, there may be compatibility issues between tactile paving studs and accessories produced by different manufacturers, leading to installation failures. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an embossed one-piece molded tactile paving stud, which aims to improve the compatibility issues that may exist between tactile paving studs and accessories produced by different manufacturers in the prior art, resulting in the inability to install smoothly.

The top of each of the fixing blocks has a reserved hole, and the interior of each of the reserved holes is rotatably connected to a fixing bolt.

[0009] As a further description of the above technical solution:

[0010] The tactile paving nails have drainage outlets at equal intervals on both the left and right sides, and water inlets at equal intervals on the top of the tactile paving nails. The bottoms of the multiple water inlets are connected to the corresponding drainage outlets.

[0011] As a further description of the above technical solution:

[0012] The sliding groove has sliding grooves on both the left and right sides inside, and the two sliding blocks are fixedly connected to sliders on the left and right sides. The sliders are slidably connected to the interior of the corresponding sliding grooves.

[0013] As a further description of the above technical solution:

[0014] The bottom left and right sides of the tactile paving nail are provided with fixing grooves, and rubber pads are fixedly connected inside the two fixing grooves.

[0031] 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.

[0032] Reference Figure 2 , Figure 3 and Figure 4This utility model provides an embodiment of an embossed, one-piece molded tactile paving stud 3, comprising a base 1, which serves as the supporting foundation for the entire tactile paving stud 3 and provides a stable mounting platform for other components. The tactile paving stud 3 is mounted on the top of the base 1, serving as a raised warning feature to facilitate perception for the visually impaired. A sliding groove 4 is provided at the bottom of the tactile paving stud 3, providing space for the movement of sliding blocks 5, allowing the tactile paving stud 3 a certain degree of mobility. Sliding blocks 5 are slidably connected to the front and rear sides of the sliding groove 4, allowing the sliding blocks 5 to slide within the sliding groove 4 and adjust their position when subjected to external force. Grooves 6 are provided on the left and right sides of the bottom of the two sliding blocks 5, providing mounting positions for springs 7 and limiting blocks 8. Springs 7 are fixedly connected to one side of each of the multiple grooves 6, providing a buffering effect when the tactile paving stud 3 is subjected to pressure, reducing impact damage to the components. Limiting blocks 8 are fixedly connected to the other ends of the multiple springs 7, allowing the limiting blocks 8 to... To limit the excessive displacement of the tactile paving studs 3 and ensure their stability, the base 1 has a moving groove 9 on both the front and rear sides of the top. The moving groove 9 is connected to the limiting groove 10 and together guides the sliding path of the extrusion block 11. The left and right ends of the base 1 have limiting grooves 10. The limiting grooves 10 can accommodate the extrusion block 11 and allow it to slide within a certain range. Multiple limiting grooves 10 are connected to the corresponding moving grooves 9. Extrusion blocks 11 are slidably connected inside the multiple limiting grooves 10. When the tactile paving studs 3 are subjected to force, the extrusion blocks 11 can disperse the pressure by moving and deforming. The left and right sides of the base 1 are provided with connecting mechanisms 2. The connecting mechanisms 2 are used to connect the tactile paving bricks, so that the tactile paving studs 3 are tightly connected to the tactile paving bricks, ensuring the overall structural integrity. The top of the tactile paving studs 3 is fixedly connected with protrusions 21 at equal intervals. The protrusions 21 can increase the friction and tactile identification of the surface of the tactile paving studs 3. The protrusions 21 are made of rubber material, which can provide better tactile feel and has a certain elasticity and anti-slip performance.

[0033] Reference Figure 1 and Figure 5The connecting mechanism 2 includes two horizontal plates 201, which serve as the main frame of the connecting mechanism 2 and provide an installation base for other components. The adjacent sides of the two horizontal plates 201 are fixedly connected to the left and right sides of the base 1, thus firmly connecting the connecting mechanism 2 to the base 1 to form an integral structure. Each of the two horizontal plates 201 has a movable groove 202 on its far side. The movable groove 202 provides a guide path for the sliding of the fixing block 203, allowing the fixing block 203 to flexibly adjust its position in a specific direction. Fixing blocks 203 are slidably connected to both ends of the two movable grooves 202, allowing the fixing blocks 203 to move within the movable grooves 202, facilitating the connection of different tactile paving bricks. Multiple fixing blocks 203... Each of the top sections has a pre-drilled hole 204, which provides space for the installation of the fixing bolts 205, allowing the fixing bolts 205 to pass through. The fixing bolts 205 are rotatably connected inside the pre-drilled holes 204, and can rotate within the pre-drilled holes 204, facilitating tightening when connecting the tactile paving bricks. The outer walls of the fixing bolts 205 are slidably connected with washers 20. The washers 20 increase the contact area between the fixing block 203 and the tactile paving brick when the fixing bolts 205 are tightened, improving the stability of the connection. The bottom of the washers 20 fits against the top of the corresponding fixing block 203, ensuring that the washers 20 can evenly distribute the pressure during the fixing process, making the connection more secure and reliable.

[0034] Reference Figure 2 , Figure 3 and Figure 4The tactile paving nail 3 has drainage outlets 12 equidistantly spaced on both its left and right sides. These outlets effectively drain water from the sides of the nail, preventing rainwater from accumulating around it and affecting its normal use, thus ensuring smooth drainage in rainy conditions. The top of the nail 3 has water inlets 13 equidistantly spaced, allowing rainwater falling on its top to smoothly enter the internal drainage channel, preventing water accumulation and slipperiness. The bottoms of the multiple water inlets 13 are connected to the corresponding drainage outlets 12, ensuring that rainwater can flow quickly from the water inlets 13 to the drainage outlets 12 and be discharged along a predetermined path, forming an efficient drainage system. The sliding groove 4 has sliding grooves 14 on both its left and right sides. These grooves 14 define a precise trajectory for the slider 15, allowing it to move only in a straight line, enhancing stability and directionality. Slider 15s are fixedly connected to the left and right sides of the two sliding blocks 5, and the sliders 15 and the grooves 14 are matched... The sliding block 5 slides more smoothly and steadily in the sliding groove 4, reducing the adverse effects caused by shaking or displacement. The bottom left and right sides of the tactile paving nail 3 are provided with fixing grooves 16. The fixing grooves 16 provide specific installation positions for the rubber pads 17, so that they can be accurately placed at the bottom of the tactile paving nail 3. The rubber pads 17 are fixedly connected inside the two fixing grooves 16. The rubber pads 17 can play a buffering role when the tactile paving nail 3 is connected to the base 1, reducing the hard collision and friction between the two, and also enhancing the tightness and stability of the connection. The front and rear sides of the interior of the multiple grooves 6 are provided with limiting grooves 2 18. The limiting grooves 2 18 limit the movement range of the limiting block 2 19, ensuring that the limiting block 2 19 can only move in a specific area. The front and rear sides of one end of the multiple limiting blocks 1 8 are fixedly connected with limiting blocks 2 19. The synergistic effect of the limiting blocks 2 19 and the limiting grooves 2 18 further precisely constrains the displacement of the tactile paving nail 3, preventing it from shaking or deviating excessively.

[0035] Working principle: When using an embossed one-piece molded tactile paving stud 3, before installation, first place the base 1 in the predetermined position and fix it. At this time, simply align the tactile paving stud 3 roughly with the base 1 and then press it down gently. During the pressing process, the sliding block 5 descends along with the tactile paving stud 3. When the sliding block 5 enters the area of ​​the moving groove 9 at the top of the base 1, since the limiting groove 10 is connected to the moving groove 9, if the tactile paving stud 3 has a certain angular deviation, during the descent, the sliding block 5 will squeeze the extrusion block 11 in the limiting groove 10. The extrusion block 11 will be displaced or deformed due to the extrusion, and at the same time, the reaction force will push the sliding block 5 to make fine adjustments, thereby guiding the tactile paving stud 3 to automatically correct its position, ensuring that the tactile paving stud 3 can be accurately installed on the base 1, improving installation efficiency and quality, and ensuring that the tactile paving stud 3 can play a good guiding role in the laying of tactile paving.

[0036] Furthermore, when it is necessary to connect the tactile paving stud 3 to other components, firstly, according to the size of the component to be connected and the mounting hole position, slide the fixing block 203 in the moving groove 202 to the appropriate position. Then, the fixing bolt 205 in the reserved hole 204 plays its role. Pass the fixing bolt 205 through the reserved hole 204 and screw it into the corresponding mounting hole of the component to be connected. During the rotation of the fixing bolt 205, since the fixing bolt 205 and the reserved hole 204 are rotatably connected, the fixing bolt 205 can be tightened smoothly, thereby firmly connecting the tactile paving stud 3 to other components.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
