Description

Technical Field

[0001] The utility model relates to the technical field of curbstones, in particular to a luminous curbstone. Background Art

[0002] Curbstones are marker stones placed between the road surface and other structures. Curbstones are usually required between the dividing strip and the road surface of urban roads, and between the sidewalk and the road surface.

[0003] For example, the Chinese patent with the authorization announcement number CN219808220U and the authorization announcement date of October 10, 2023 discloses "A Light-emitting Curbstone with Easy Installation". In this patent, two fixing sleeves (also called connecting sleeves) and a fixing structure for limiting the angle of the light bar (also called angle limiting sleeve) and other plastic parts are involved at both ends of the lamp tube. Because these plastic parts are distributed at both ends of the lamp tube, the plastic parts at both ends are usually mirror images. However, due to the existence of limiting grooves in the fixing sleeves and the setting of the fixing structure, the structures of the plastic parts at both ends are interchangeable left and right after mirroring. Two sets of molds need to be designed for the plastic parts during production, and they need to be installed at the corresponding end during installation. They cannot be installed interchangeably left and right, which ultimately leads to a significant impact on production costs and installation convenience. Utility Model Content

[0004] The utility model aims to provide a luminous curbstone, which can realize left-right interchangeable installation by improving the structure of plastic parts, thereby reducing production costs and improving installation convenience.

[0005] The above technical object of the present utility model is achieved by the following technical solutions: A luminous curbstone, comprising a curbstone body with a light-transmitting groove on the front side, a transparent lamp tube arranged inside the curbstone body, two connecting sleeves arranged at both ends of the transparent lamp tube and combined inside the curbstone body, a lamp strip arranged inside the transparent lamp tube and aligned with the light-transmitting groove, two angle limiting sleeves symmetrically arranged between the connecting sleeves and the lamp strip to limit the angle of the lamp strip, two sealing components arranged inside the connecting sleeves, a male docking plug connected to one end of the lamp strip through a power cord and passing through the angle limiting sleeve and the sealing component, a female docking plug connected to the other end of the lamp strip through a power cord and passing through the angle limiting sleeve and the sealing component.

A second connecting groove symmetric to the first connecting groove along the first mirror plane is arranged on the inner circle of the second annular installation part; after the second annular installation part is installed, it abuts against the first annular installation part; when one of the angle limiting sleeves is installed, the extension sections of the two connecting parts are installed in the two first limiting grooves, the main body section of one of the connecting parts is installed between one second limiting groove and the first connecting groove, and the main body section of the other connecting part is installed between the other second limiting groove and the second connecting groove; when the other angle limiting sleeve is installed, the extension sections of the two connecting parts are installed in the two second limiting grooves, the main body section of one of the connecting parts is installed between one first limiting groove and the first connecting groove, and the main body section of the other connecting part is installed between the other first limiting groove and the second connecting groove.

[0006] By adopting the above technical solution, since the first mirror plane intersects with the second mirror plane, the installation plane of the light bar is parallel to the first mirror plane. At this time, based on the symmetrical arrangement of the two angle limit sleeves, if the two connecting sleeves are facing the same direction, the installation angles of the two angle limit sleeves are symmetrical with the first mirror plane; however, a first limit groove, a second limit groove symmetrical to the first limit groove along the first mirror plane, a first connecting groove, and a second connecting sleeve symmetrical to the first connecting groove along the first mirror plane are arranged in the second annular mounting portion of the connecting sleeve, so that the structures of the two connecting sleeves are the same and interchangeable installation is achieved; at the same time, the angle limit sleeve includes a first annular mounting portion, two connecting portions arranged on the first annular mounting portion and symmetrical along the second mirror plane, so that the two The angle limit sleeves have the same structure and can be installed interchangeably; the second annular mounting part conflicts with the first annular mounting part after installation; when one of the angle limit sleeves is installed, the extended sections of the two connecting parts are installed in the two first limit grooves, the main section of one connecting part is installed between a second limit groove and the first connecting groove, and the main section of the other connecting part is installed between the other second limit groove and the second connecting groove; when the other angle limit sleeve is installed, the extended sections of the two connecting parts are installed in the two second limit grooves, the main section of one connecting part is installed between a first limit groove and the first connecting groove, and the main section of the other connecting part is installed between the other first limit groove and the second connecting groove; finally, the installation of the connecting sleeve and the angle limit sleeve is realized.

Let the cross-section that divides the connecting sleeve 3 into two left-right mirror-image parts be the first mirror plane; the two angle limit sleeves 5 have the same structure and are interchangeably installed. Let the cross-section that divides the angle limit sleeve 5 into two left-right mirror-image parts be the second mirror plane; the first mirror plane intersects with the second mirror plane, and the second mirror plane is parallel to the installation plane of the lamp strip 4.

[0023] As Figures 3 to 5 shown, the angle limit sleeve 5 includes a first annular installation part 51 and two connecting parts 52 arranged on the first annular installation part 51 and symmetric along the second mirror plane. The connecting part 52 includes a main body section 521 in a "U" shape and extension sections 522 arranged at both ends of the main body section 521. A card slot 53 for the lamp strip 4 to be embedded is formed between the adjacent extension sections 522 of the two connecting parts 52.

[0024] As Figures 3 to 5 shown, an installation hole 31 corresponding to the transparent lamp tube 2 is arranged inside the connecting sleeve 3. A second annular installation part 32 is arranged inside the installation hole 31. Two first limiting grooves 321 distributed on both sides of the first mirror plane are arranged on the inner ring of the second annular installation part 32. Two second limiting grooves 322 symmetric to the two first limiting grooves 321 along the first mirror plane are arranged on the inner ring of the second annular installation part 32. A first connecting groove 323 located between the first limiting groove 321 and the second limiting groove 322 is arranged on the inner ring of the second annular installation part 32. A second connecting groove 324 symmetric to the first connecting groove 323 along the first mirror plane is arranged on the inner ring of the second annular installation part 32.

[0025] As Figures 3 to 5As shown, the second annular mounting portion 32 conflicts with the first annular mounting portion 51 after installation; when one of the angle limiting sleeves 5 is installed, the extension sections 522 of the two connecting portions 52 are installed in the two first limiting grooves 321, wherein the main section 521 of one connecting portion 52 is installed between a second limiting groove 322 and the first connecting groove 323, and the main section 521 of the other connecting portion 52 is installed between the other second limiting groove 322 and the second connecting groove 324; when the other angle limiting sleeve 5 is installed, the extension sections 522 of the two connecting portions 52 are installed in the two second limiting grooves 322, wherein the main section 521 of one connecting portion 52 is installed between a first limiting groove 321 and the first connecting groove 323, and the main section 521 of the other connecting portion 52 is installed between the other first limiting groove 321 and the second connecting groove 324.

[0026] like Figure 2 , Figure 3 and Figure 6 As shown, the two sealing assemblies 6 have the same structure and can be installed interchangeably. The sealing assembly 6 includes an annular embedded portion 61 for embedding in the connecting sleeve 3 and pressing the annular sleeve of the angle limiting sleeve 5, a curved tube portion 62 arranged on the annular embedded portion 61, a threaded tube portion 63 arranged on the curved tube portion 62, an annular sealing ring 64 arranged on the circumferential side of the annular embedded portion 61, and a sealing cover 65 threadedly connected to the threaded tube portion 63. Strip portions 66 distributed in a circumferential array are arranged on the end surface of the threaded tube portion 63, and the inner ring of the sealing cover 65 is provided with an annular inclined surface 651 that drives multiple strip portions 66 to deform to clamp the circumferential side of the power cord during the threaded connection process of the sealing cover 65.

[0027] like Figure 3 As shown, two fins 33 symmetrically arranged along the first mirror plane are provided on the circumferential side of the connecting sleeve 3 .

[0028] Implementation effect: Since the first mirror plane intersects with the second mirror plane, the installation plane of the light bar 4 is parallel to the first mirror plane. At this time, on the basis of the symmetrical arrangement of the two angle limit sleeves 5, if the two connecting sleeves 3 are facing the same direction, the installation angles of the two angle limit sleeves 5 are symmetrical with the first mirror plane; however, a first limiting groove 321, a second limiting groove 322 symmetrical to the first limiting groove 321 along the first mirror plane, a first connecting groove 323, and a second connecting groove 324 symmetrical to the first connecting groove 323 along the first mirror plane are arranged in the second annular mounting portion 32 of the connecting sleeve 3, so that the structures of the two connecting sleeves 3 are the same and interchangeable installation is achieved; at the same time, the angle limit sleeve 5 includes a first annular mounting portion 51, two connecting portions 52 arranged on the first annular mounting portion 51 and symmetrical along the second mirror plane, so that the structures of the two angle limit sleeves 5 are the same and interchangeable installation is achieved;

[0029] After installation, the second annular mounting portion 32 conflicts with the first annular mounting portion 51; when one of the angle limiting sleeves 5 is installed, the extension sections 522 of the two connecting portions 52 are installed in the two first limiting grooves 321, wherein the main section 521 of one connecting portion 52 is installed between a second limiting groove 322 and the first connecting groove 323, and the main section 521 of the other connecting portion 52 is installed between the other second limiting groove 322 and the second connecting groove 324; when the other angle limiting sleeve 5 is installed, the extension sections 522 of the two connecting portions 52 are installed in the two second limiting grooves 322, wherein the main section 521 of one connecting portion 52 is installed between a first limiting groove 321 and the first connecting groove 323, and the main section 521 of the other connecting portion 52 is installed between the other first limiting groove 321 and the second connecting groove 324; finally, the installation of the connecting sleeve 3 and the angle limiting sleeve 5 is realized.

[0030] Since the part where the sealing assembly 6 is connected to the connecting sleeve 3 is mainly the annular embedded part 61, the two sealing assemblies 6 can be identical in structure and interchangeably installed, so as to reduce production costs and improve installation convenience. The arrangement of multiple strip portions 66 distributed in a circumferential array and the arrangement of annular bevels 651 in the sealing cover 65 drive multiple strip portions 66 to deform to clamp the power cord during the threaded connection of the sealing cover 65, thereby avoiding the pulling of the connection between the power cord and the light bar 4 when pulling the male docking plug 7 and the female docking plug 8, and avoiding the connection between the power cord and the light bar 4 from breaking due to pulling. The fins 33 of the connecting sleeve 3 are solidified in the curb body 1, and the arrangement of the fins 33 can improve the firmness of the connection with the curb body 1.
