Description

Technical Field

[0001] The utility model relates to the technical field of traffic sign guidance, in particular to a luminous sign board which is convenient for high-altitude maintenance. Background Art

[0002] Luminous signs can bring certain conveniences to traffic and play an important role in traffic management. However, after the luminous sign is fixed, the back panel covering the internal light source structure is directly fixed to the beam by welding, and the entire sign is fixed to the gantry. Therefore, the back panel cannot be opened at high altitudes, making it impossible to perform high-altitude maintenance. Utility Model Content

[0003] The purpose of the utility model is to provide a luminous signboard that is easy to maintain at high altitude, so as to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The technical solution adopted to solve the above-mentioned technical problems is as follows: a luminous signboard that is easy to maintain at high altitude, comprising: an outer frame; a longitudinal rod, with its two ends respectively mounted on the upper and lower sides of the outer frame, and extended edges are provided on both sides of the longitudinal rod and the left and right inner sides of the outer frame; a transverse rod, with its two ends respectively mounted on the left inner side or the right inner side of the longitudinal rod or the outer frame, and an installation gap is provided between the transverse rod and the corresponding extension edge; a back plate, with its two sides respectively inserted into the corresponding installation gaps, and the thickness of the back plate being less than the width of the installation gap; a pressing piece mounted on the end of the longitudinal rod, and the pressing piece presses the back plate against the outer frame.

[0005] This technical solution has at least the following beneficial effects: During installation, the back panel is inserted into the installation gaps on both sides and is equipped with retaining clips. The retaining clips ensure the stability of the back panel after insertion and prevent it from loosening. When performing high-altitude maintenance on the gantry, the retaining clips can be loosened and the back panel can be pulled out of the installation gaps on both sides. This allows the back panel to be removed at high altitude for maintenance of the internal structure. The removal and installation of the back panel is also convenient, which improves maintenance efficiency.

[0006] As a further improvement to the above technical solution, the clamping member includes a bolt and a clamping block. The clamping block is fixed to the end of the longitudinal rod by the bolt, and the two ends of the clamping block respectively press against the back plate on the corresponding side. By removing and installing the bolt, the clamping block can be easily removed from the longitudinal rod.

[0007] As a further improvement to the above technical solution, the clamping block includes a mounting section, two inclined sections, and two pressing sections. The two inclined sections are symmetrically located at either end of the mounting section, and the two pressing sections are symmetrically located at the end of the inclined section away from the mounting section. The clamping block can provide a large clamping preload force, providing strong and stable support for the backboard and preventing it from shaking.

[0008] As a further improvement of the above technical solution, the angle between the inclined section and the mounting section is an inclination angle, and the inclination angle is between 110 degrees and 135 degrees.

[0009] As a further improvement of the above technical solution, reinforcing ribs are provided on both sides of the buckling block and in the middle of the inclined section to improve the overall strength of the buckling block.

[0010] As a further improvement of the above technical solution, the side of the pressing section pressing against the back plate is provided with anti-slip embossing to reduce the relative sliding between the pressing section and the back plate.

[0011] As a further improvement to the above technical solution, reinforcement clips are installed at the ends of the transverse bars. These clips include wedge-shaped blocks that fit into the mounting gaps. These wedge-shaped blocks can press the back panel against the corresponding extended edges. After the back panel is inserted into the mounting gaps on both sides, the reinforcement clips are installed at the ends of the transverse bars, so that the wedge-shaped blocks fit into the remaining mounting gaps between the back panel and the transverse bar ends. This further stabilizes the back panel and prevents it from shaking or rattling.

[0012] As a further improvement of the above technical solution, the reinforcement clip includes a hook arranged on one side of the wedge block, and the transverse rod is provided with a slot for the hook to be embedded.

[0013] As a further improvement to the above technical solution, the slot is an L-shaped slot with both ends extending through the transverse rod. After the hook is engaged with the slot, the hook can be pressed from the other end of the L-shaped slot to remove the hook from the slot, thereby facilitating removal of the reinforcement clip and enabling low-cost maintenance.

[0014] As a further improvement to the above technical solution, the wedge-shaped block is provided with a clearance groove extending therethrough to provide deformation space for the wedge-shaped block. The clearance groove improves the elastic deformation capability of the wedge-shaped block, allowing the wedge-shaped block to be more securely embedded between the backboard and the transverse rod, thereby ensuring the stability of the backboard.

[0027] Reference Figure 1-6 The luminous signboard for high-altitude maintenance includes an outer frame 100, a sign board 110 is installed on the front side of the outer frame 100, and the sign board 110 is used to display traffic sign information. A longitudinal rod 200 and a transverse rod 300 are installed on the rear side of the outer frame 100.

[0028] The ends of the longitudinal rod 200 are welded to the upper and lower edges of the outer frame 100, respectively. Extended edges 210 extend from the left and right sides of the longitudinal rod 200. These extended edges 210 are thinner than the longitudinal rod 200, and one side of the extended edge 210 is flush with the longitudinal rod 200. Extended edges 210 are also provided on the inner sides of the left and right sides of the outer frame 100.

[0029] Three longitudinal rods 200 are provided, arranged side by side in the transverse direction. A set of transverse rods 300 is installed between two adjacent longitudinal rods 200, and between the longitudinal rods 200 at the end and the inner side of the outer frame on the corresponding side. A set of transverse rods 300 includes two transverse rods 300 arranged one above the other. The length direction of the transverse rods 300 is perpendicular to the length direction of the longitudinal rods 200.

[0030] The ends of the transverse rod 300 located between two adjacent longitudinal rods 200 are welded to the sidewalls of the two adjacent longitudinal rods 200, with installation gaps 310 reserved between the transverse rod 300 and the corresponding extension edges 210. The ends of the transverse rod 300 located between the longitudinal rod 200 and the side edges of the outer frame 100 are welded to the inner sidewalls of the longitudinal rod 200 and the outer frame 100, with similar installation gaps 310 reserved between the transverse rod 300 and the corresponding extension edges 210. Four back panels 400 are also mounted on the rear side of the outer frame 100 to cover the backside of the sign board 110. After the longitudinal rods 200, transverse rods 300, outer frame 100, and sign board 110 are assembled, the back panels 400 can be inserted between the transverse rods 300 and sign board 110, with the ends of the back panels 400 nestled in the installation gaps 310 at the corresponding side positions, thereby facilitating installation of the back panels 400. It should be noted that the back plate 400 has a certain elastic deformation capability, and the width of the installation gap 310 is slightly larger than the thickness of the back plate 400 , so that both sides of the back plate 400 can be smoothly embedded in the corresponding installation gap 310 .

[0031] During actual production, the size of the signboard 110 needs to be designed based on actual display requirements, and the number of longitudinal rods 200 is also designed based on the size of the signboard 110 and other strength requirements. Therefore, an outer frame 100 may include one, two, or more longitudinal rods 200. If only one longitudinal rod 200 is installed in an outer frame 100, two groups of transverse rods 300 are provided, with the two groups of transverse rods 300 being respectively disposed between the longitudinal rod 200 and the left and right inner sides of the outer frame 100. Similarly, each group of transverse rods 300 may include one or multiple transverse rods 300 arranged side by side in an upper and lower direction. The number of groups of transverse rods 300 is the number of longitudinal rods 200 plus one, and the number of back panels 400 is the same as the number of groups of transverse rods 300.

[0032] Buckling members 500 are installed at both ends of the longitudinal rod 200 . The buckling members 500 can press the back plate 400 against the upper and lower positions of the outer frame 100 , thereby improving the stability of the back plate 400 .

[0033] The pressing member 500 includes a bolt 510 and a pressing block 520. The pressing block 520 includes a mounting section 521 in position, two inclined sections 522 located at both ends of the mounting section 521, and two pressing sections 523. The two pressing sections 523 are respectively connected to one end of the two inclined sections 522 away from the mounting section 521, and the pressing section 523 is located on one side of the inclined section 522 away from the pressing section 523. The two inclined sections 522 and the two pressing sections 523 are symmetrically distributed with respect to the center plane of the mounting section 521. The mounting section 521 and the pressing section 523 are distributed in parallel. The angle between the plane where the mounting section 521 is located and the plane where the inclined section 522 is located is the inclination angle, and the inclination angle is between 110 degrees and 130 degrees. Specifically, the inclination angle is 120 degrees.

[0034] The bolt 510 comprises a screw, a washer, and a nut. A T-slot 530 is provided on the side of the longitudinal rod 200 that is away from the extended edge 210. The length of the T-slot 530 is aligned with the length of the longitudinal rod 200, and the ends of the T-slot 530 extend through both ends of the longitudinal rod 200. The screw head is inserted into the T-slot 530, and the screw body extends beyond the opening of the T-slot 530, where the screw head abuts against the inner wall of the T-slot 530. A circular hole is provided in the center of the mounting section 521 for the screw body to pass through. After the mounting section 521 and the washer are sequentially inserted into the screw body and the nut is tightened onto the screw body, the pressing block 520 can be fixed to the longitudinal rod 200, with the pressing section 523 abutting against the side of the backplate 400 away from the sign plate 110, thereby stabilizing the backplate 400. The installation position of the buckling block 520 can be adjusted according to actual conditions, and is highly flexible.

[0035] Reinforcing ribs 600 are provided on both edges of the pressing block 520, away from the back plate 400. A reinforcing rib 600 is also provided in the middle of the inclined section 522, away from the back plate 400, thereby enhancing the overall strength of the pressing block 520. Multiple grooves are arranged side by side on the side of the pressing section 523, which is used to press against the back plate 400, forming an anti-slip embossing 700 to reduce relative sliding between the pressing section 523 and the back plate 400.

[0036] Reference Figure 4 In another embodiment, the extended edges 210 on both sides of the longitudinal rod 200 can be fixed to the longitudinal rod via connecting posts. A predetermined ventilation gap is left between the longitudinal rod 200 and the extended edges 210, and the width of the ventilation gap is smaller than the width of the back plate 400. It can be understood that the connection structure between the extended edges 210 and the longitudinal rod 200 is diverse and can be processed and manufactured with different existing materials, thereby reducing production costs.

[0037] In other embodiments, the pressing piece may also be an L-shaped block riveted to the longitudinal rod 200 by rivets, with one end of the L-shaped block riveted to the longitudinal rod 200 and the other end abutting against the end of the back plate 400 away from the sign plate 110 .

[0038] Generally, a light source structure is installed on the back side of the sign board 110, and the light source structure provides a light source for the sign board 110. By removing the back panel 400, the light source structure can be exposed, so that the light source structure can be repaired and the normal use of the luminous sign board can be guaranteed. During installation, the back panel 400 is embedded in the installation gaps 310 on both sides, and the buckling parts 500 are installed to ensure the stability of the back panel 400 and prevent the back panel from loosening. When maintenance is required, high-altitude maintenance work can be carried out on the gantry, that is, the buckling parts 500 are first loosened, and the back panel 400 is pulled out from the installation gaps 310 on both sides, so that the back panel 400 can be easily disassembled at high altitude to repair the internal structure, and the disassembly and assembly of the back panel 400 is relatively convenient, which can improve maintenance efficiency.

[0039] Reference Figure 1-6 , reinforcement clips 800 are installed at both ends of the transverse bar 300. The reinforcement clips 800 include a wedge block 810 and a hook 820. The larger end of the wedge block 810 is integrally connected to the hook 820 at a position away from the hook tip. The wedge block 810 and the hook 820 form a U-shaped structure as a whole. A slot 830 is provided at the top position of both ends of the transverse bar 300. The two ends of the slot 830 pass through the top and side wall of the transverse bar 300 respectively, making the slot 830 an L-shaped slot with an L-shaped cross-section. When the smaller end of the wedge block 810 is embedded between the back panel 400 and the transverse bar 300, the side edge of the back panel 400 can be pressed against the extension edge 210, thereby stabilizing the back panel 400 and preventing the back panel 400 from shaking. At the same time, the hook 820 is embedded in the slot 830, and the hook tip of the hook 820 protrudes from the bottom of the slot 830, connecting the wedge block 810 to the transverse rod 300, firmly positioning the wedge block 810 and preventing it from falling. In addition, by pressing the hook tip of the hook 820 through the opening at the bottom of the slot 830, the hook 820 can be easily removed from the slot 830, thereby facilitating the removal of the reinforcement clip 800 and the back plate 400.

[0040] The wedge block 810 is provided with a clearance groove 811 extending along the length of the transverse rod 300. The clearance groove 811 improves the elastic deformation capability of the wedge block 810, thereby facilitating the clamping of the wedge block 810 between the back plate 400 and the transverse rod 300, thereby ensuring the stability of the back plate 400. In addition, the space provided by the clearance groove 811 also makes it easier for workers to grasp the reinforcement clip 800, thereby facilitating its installation and removal.

[0041] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
