Abstract
Description
Technical Field
[0001] The utility model relates to a road spike in traffic equipment, in particular to an assembled road spike with a large diameter, belonging to the technical field of traffic equipment. Background Art
[0002] The applicant disclosed an optimized solar road stud in Chinese patent application No. 2022202961520, which includes a metal lower shell and a pressure ring fixedly connected to the metal lower shell by screws. The metal lower shell is a cavity with an upper opening, and a mounting seat is fixedly installed in the cavity of the metal lower shell. The solar panel and the light-emitting diode are mounted on the mounting seat, and the mounting seat is inserted into the cavity. The lower part of the mounting seat in the cavity is encapsulated with glue. The upper end surface of the metal lower shell has a circle of closed upper protrusions, and the upper protrusions are in the shape of a "cross". The outer contours of the four ends of the outer end of the "cross" are all arc-shaped, and the upper end surface of the protrusion has a sealing ring groove. A sealing ring is installed in the sealing ring groove, and a transparent plastic top cover is provided on the upper convexity. The top cover has a lamp cavity adapted to the light-emitting diode, and the lower end of the top cover has a continuous or discontinuous skirt. In the specific embodiment, the skirt at the lower end of the top cover is discontinuous in four sections, and the four sections of the skirt are adapted to the outer contours of the four ends of the "cross" outer end, and the shape of the skirt is adapted to the outer contour of the upper convexity. After the top cover is buckled on the upper convexity, the skirt is tightly fitted with the upper convexity and the inner surface of the top cover corresponding to the upper part of the sealing ring is pressed on the sealing ring. The outer periphery of the top cover has a pressing edge, and the pressing ring has a pressing edge corresponding to the pressing edge, and the pressing edge is pressed on the pressing edge. This road spike is waterproofed by a sealing ring, which eliminates the need for a glue filling process during production and improves production efficiency. With increasing market demand for larger road spikes, the research, development, and production of road spikes are also moving toward larger sizes. Larger sizes, however, can increase the overall load-bearing capacity of the upper cover when heavy objects are applied, placing higher demands on strength. For example, when producing a 14cm diameter road spike using the aforementioned structure, the technical solution disclosed in Chinese Patent Application No. 2022210541032 was employed to ensure the strength of the road spike. However, when producing a 15cm diameter road spike using the technical solution disclosed in Chinese Patent Application No. 2022210541032, the following problems were discovered during use that required resolution: First, the rate of pressure-induced damage to the upper cover during use was significantly higher compared to the 14cm diameter product; second, moisture could enter the road spike in relatively high moisture conditions. Summary of the Invention
[0003] The purpose of the utility model is to overcome the above-mentioned problems existing in the current production of large-diameter road spikes and to provide an assembled large-diameter solar road spike.
[0004] In order to achieve the purpose of the utility model, the following technical solutions are adopted: an assembled large-diameter solar road stud, comprising a metal lower shell, a pressure ring fixedly connected to the metal lower shell by screws, the metal lower shell being a cavity with an upper opening, a mounting seat fixedly installed in the cavity of the metal lower shell, a solar cell panel and a light-emitting diode being mounted on the mounting seat, the mounting seat being inserted into the cavity, and the lower part of the mounting seat in the cavity being encapsulated with glue, a circle of closed upper convexities being provided on the upper end surface of the metal lower shell, the upper convexities being in the shape of a "cross", the outer contours of the four ends of the outer end of the "cross" being all arc-shaped, and a closed upper convexity being provided on the upper end surface of the upper convexity. The sealing ring groove is equipped with a transparent plastic top cover on the upper convexity. The top cover has a lamp cavity adapted to the light-emitting diode. The lower end of the top cover has a skirt. The shape of the skirt is adapted to the outer contour of the upper convexity. After the top cover is buckled on the upper convexity, the skirt and the upper convexity are tightly fitted. The outer periphery of the top cover has a pressing edge, and the pressing ring has a pressing edge corresponding to the pressing edge. The pressing edge is pressed on the pressing edge. An O-ring is installed in the sealing ring groove. A circle of flat pads is integrally connected to the inner wall of the O-ring. The flat pads are provided with holes. The shape of the holes is adapted to the contour of the cavity. The diameter of the large-diameter solar road stud is greater than or equal to 15 cm.
[0005] Furthermore, the height of the road spike is 49-51 mm, and the height of the top cover is greater than or equal to 14 mm.
[0006] Furthermore, the flat gasket is located in the middle of the O-ring in the height direction.
[0007] Furthermore, the flat pad is thick in the middle and thin at the edges.
[0008] The positive and beneficial technical effects of the utility model are as follows: the addition of a rubber flat pad made of the same material as the sealing ring can not only act as a buffer when under pressure, which helps the road spike to bear impact loads, but also helps to improve the sealing effect. While the height of the entire road spike remains unchanged, the height (thickness) of the top cover is increased, which enhances the pressure resistance of the top cover. This road spike structure works well on road spikes with a diameter of 15 cm. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The utility model is an improvement based on Chinese patent application No. 2022202961520. Compared with the technical solution of that patent, it mainly makes two improvements: one is the addition of a flat pad; the other is the increase in the height of the top cover.
[0016] As shown in the accompanying drawings, an assembled large-diameter solar road stud comprises a metal lower shell 3 and a pressure ring 2 fixedly connected to the metal lower shell by screws. The metal lower shell is an open cavity with a mounting base 4 fixedly mounted within the cavity. A solar panel and light-emitting diode are mounted on the mounting base. (5) indicates the solar panel mounting area. The mounting base is inserted into the cavity, and the lower portion of the mounting base within the cavity is potted with glue. The upper end surface of the metal lower shell has a closed upper protrusion 7. This protrusion is in the shape of a cross, with the outer contours of the four ends of the cross being arc-shaped 6. The upper end surface of the protrusion has a sealing ring groove, and a transparent plastic top cover 1 is mounted on the protrusion. The height of the road stud is 49-51 mm, and the height of the top cover is greater than or equal to 14 mm. The flat pad is thick in the middle and thin at the edges, which effectively blocks moisture intrusion and prolongs the life of the road stud.
[0017] The top cover contains a lamp cavity 10 adapted for the LED. The lower end of the top cover has a skirt. The skirt is divided into four discontinuous segments, each of which conforms to the arc-shaped outer contours of the four ends of the "cross" shape. The shape of the skirt conforms to the outer contour of the upper protrusion. When the top cover is snapped onto the upper protrusion, the skirt and the upper protrusion fit tightly together. The outer periphery of the top cover has a pressure edge, and the pressure ring has a pressure edge corresponding to the pressure edge, which is pressed against the pressure edge. An O-ring 8 is installed in the sealing ring groove. A flat washer 9 is integrally connected to the inner wall of the O-ring and is located in the middle of the O-ring's height. A hole 12 is formed in the flat washer, the shape of which conforms to the contour of the cavity. In this embodiment, the diameter of the large-diameter solar road stud is greater than or equal to 15 cm and less than or equal to 16 cm.
[0018] After describing the implementation mode of the present invention in detail, people familiar with the technology can clearly understand that various changes and modifications can be made without departing from the scope and spirit of the above-mentioned patent application. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are within the scope of the technical solution of the present invention, and the present invention is not limited to the implementation mode of the examples given in the specification.
