Description

Technical Field

[0001] This utility model belongs to the field of navigation light fixing technology, and relates to a quick fixing device for a mobile apron navigation light. Background Technology

[0002] Mobile helipads, serving as temporary takeoff and landing platforms, are widely used in emergency rescue, field operations, and other scenarios. Their navigation lights primarily provide visual guidance to pilots at night or in low-light conditions, aiding in safe takeoff, landing, and navigation. These navigation lights rely on batteries, requiring frequent disassembly and recharging after power depletion. However, traditional navigation lights are directly bolted to the helipad deck, requiring individual alignment and tightening of bolts during installation and removal. This process is time-consuming, especially in scenarios with multiple lights, where the overall assembly and disassembly time can reach tens of minutes, severely hindering the rapid deployment and recovery efficiency of the helipad. Utility Model Content

[0003] The purpose of this invention is to address the above-mentioned problems by providing a quick fixing device for mobile helipad navigation lights.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A quick-fixing device for a mobile apron navigation light includes a fixed base plate set on the apron deck. The fixed base plate has several locking seats at both ends, and the locking seats at both ends form a locking area that cooperates with the mounting base of the navigation light assembly. The locking seat at any end is connected to a locking seat drive mechanism that can drive it to move, thereby expanding or shrinking the locking area.

[0006] The lamp holder is snapped into the snap-in area. The spacing between the two snap-in slots is adjusted by the snap-in slot drive mechanism to quickly adjust the snap-in area, so that the two snap-in slots clamp or release the lamp holder. This eliminates the need for bolt fixing and enables rapid installation and removal of the navigation light assembly. The installation and removal time is reduced from minutes to seconds, improving the deployment efficiency of the apron and allowing for flexible adaptation to navigation light assemblies of different sizes.

[0007] In the aforementioned rapid fixing device for mobile apron navigation lights, the card holders at both ends of the fixed base plate are symmetrically distributed. One end of the card holder is fixedly connected to the fixed base plate as a fixed card holder, and the other end of the card holder is slidably connected to the fixed base plate as a movable card holder. The card holder driving mechanism includes several card holder driving components that are respectively connected to the movable card holder.

[0008] The symmetrical distribution of the card slots at both ends ensures uniform clamping force and prevents the lamp holder from tilting, thus ensuring the stability of the fixation. The moving card slot is controlled by the card slot drive component to slide. When the card slot drive component drives the moving card slot to approach the fixed card slot, the snap-fit ​​area shrinks to clamp the lamp holder. When it moves in the opposite direction, it releases the lamp holder, enabling the rapid installation and removal of the navigation light component.

[0009] In the aforementioned rapid fixing device for mobile apron navigation lights, the card holder drive assembly includes a fixed base, on which a sliding groove adapted to the mobile card holder is provided. A sliding guide structure is provided between the mobile card holder and the fixed base. An automatic return structure is also provided between the mobile card holder and the fixed base, which can always provide a force to the outer end of the sliding groove when the mobile card holder slides to the inner end of the sliding groove.

[0010] The movable bracket is slidably connected to the sliding groove of the fixed base. When installing or removing the navigation light assembly, the movable bracket is manually pushed into the sliding groove to expand the engagement area, making it easier to insert or release the lamp holder. The sliding guide structure between the movable bracket and the fixed base guides the sliding of the movable bracket, ensuring accurate movement and preventing jamming. The automatic return structure can reset the movable bracket to its initial position without external force, allowing it to move closer to the fixed bracket to clamp the lamp holder. The lamp holder installation is convenient and allows for quick assembly and disassembly.

[0011] In the aforementioned rapid fixing device for mobile apron navigation lights, the sliding guide structure includes a guide slide rod connected to the movable card seat, and a guide slide hole communicating with the sliding groove is provided on the outer end of the fixed seat, with the guide slide rod passing through the guide slide hole.

[0012] The guide slide rod passes through the guide slide hole of the fixed seat and slides in a sliding fit with the guide slide hole, which can guide the moving card seat to slide in a straight line, play a guiding role for the moving card seat, ensure accurate movement path, and prevent jamming.

[0013] In the aforementioned quick-fixing device for mobile apron navigation lights, the automatic return structure includes a return spring sleeved on the guide slide rod and located in the sliding groove, with both ends of the return spring abutting against the outer end of the mobile mounting base and the inner wall of the guide slide hole, respectively.

[0014] One end of the return spring abuts against the movable bracket, and the other end abuts against the inner wall of the guide slide hole. When an external force pushes the movable bracket to compress the return spring, the return spring stores energy. When the external force disappears, the return spring rebounds, causing the movable bracket to return to the fixed bracket to clamp and install the lamp holder. The lamp holder installation and fixing operation is convenient and stable. The return spring provides a stable return force to ensure reliable clamping and releasing actions. Furthermore, no additional power source is required, and the structure is compact.

[0015] In the aforementioned quick-fixing device for mobile apron navigation lights, a travel limit structure is provided on the outer end of the guide slide rod.

[0016] The travel limit structure is used to limit the maximum sliding stroke of the guide slide rod to prevent the moving bracket from falling out of the sliding groove, thus avoiding excessive displacement that could damage the mechanism and ensuring that the clamping range is always within a safe range.

[0017] In the aforementioned quick-fixing device for mobile apron navigation lights, the travel limiting structure includes a limiting ring sleeved on the guide slide rod and located outside the sliding groove, and the outer end of the guide slide rod is provided with a groove adapted to the limiting ring.

[0018] The limiting ring is embedded in the groove of the guide slide rod. When the guide slide rod moves to the point where the ring contacts the outer wall of the fixed seat, the sliding stops to prevent the moving seat from falling out of the sliding groove. The mechanical limiting has high reliability and is not affected by environmental factors. The detachable design of the ring facilitates maintenance.

[0019] In the aforementioned quick-fixing device for mobile apron navigation lights, the inner end of the mounting bracket is provided with an inverted L-shaped locking part.

[0020] The locking part contacts the top and side wall of the lamp holder to form a two-way limit. The inverted L-shaped locking part can prevent the lamp holder from jumping up and down and shifting horizontally, making it suitable for vibration environments and enhancing the stability of the lamp holder.

[0021] In the aforementioned quick-fixing device for mobile apron navigation lights, the entry end of the locking part is provided with an easy-entry chamfer, and the right angle of the locking part is also provided with an arc chamfer.

[0022] The easy-to-access chamfer guides the lamp holder to slide into the mounting part; the rounded chamfer reduces stress concentration and prevents the mounting part from breaking.

[0023] In the aforementioned quick-fixing device for mobile apron navigation lights, the fixing base plate is detachably connected to the apron deck. The fixing base plate is provided with several bolt holes adapted to the apron deck, and fixing bolts are inserted into the bolt holes.

[0024] The fixed base plate is detachably connected to the apron deck via fixing bolts. The fixed base plate is securely fixed, easy to assemble and disassemble, and easy to maintain.

[0025] Compared with existing technologies, the advantages of this utility model are: it can eliminate the bolt fixing step, realize the rapid disassembly and assembly of navigation light components, reduce the disassembly and assembly time from minutes to seconds, improve the deployment efficiency of the apron, and can flexibly adapt to navigation light components of different sizes.

Detailed Implementation

[0032] like Figures 1-5 As shown, a quick fixing device for a mobile apron navigation light includes a fixed base plate 1 set on the apron deck. Several locking seats 2 are provided at both ends of the fixed base plate 1. The locking seats 2 at both ends form a locking area 5 that cooperates with the mounting base 4 of the navigation light assembly 3. The locking seat 2 at any end is connected to a locking seat drive mechanism 6 that can drive it to move, thereby expanding or shrinking the locking area 5.

[0033] In this utility model, the fixed base plate 1 is pre-installed on the apron deck. When the navigation light assembly 3 is installed, the locking area 5 is first enlarged by the locking mechanism 6 to accommodate the mounting lamp holder 4 of the navigation light assembly 3. Then, the locking area 5 is further reduced by the locking mechanism 6 to clamp and fix the mounting lamp holder 4. When the navigation light assembly 3 is disassembled, the locking area 5 is enlarged by the locking mechanism 6 to release the mounting lamp holder 4.

[0034] The mounting bracket 4 is snapped into the snap-in area 5. The spacing between the two end clips 2 is adjusted by the clip drive mechanism 6 to quickly adjust the snap-in area 5, so that the two end clips 2 clamp or release the mounting bracket 4. This eliminates the bolt fixing step and enables the rapid installation and removal of the navigation light assembly 3. The installation and removal time is reduced from minutes to seconds, improving the deployment efficiency of the apron and allowing for flexible adaptation to navigation light assemblies 3 of different sizes.

[0035] Specifically, combining Figures 1-5As shown, the card seats 2 at both ends of the fixed base plate 1 are symmetrically distributed. One end of the card seat 2 is fixedly connected to the fixed base plate 1 as a fixed card seat 7, and the other end of the card seat 2 is slidably connected to the fixed base plate 1 as a movable card seat 8. The card seat driving mechanism 6 includes several card seat driving components 9 that are respectively connected to the movable card seat 8.

[0036] The symmetrical distribution of the two end slots 2 ensures uniform clamping force and prevents the lamp holder 4 from tilting, thus ensuring the stability of the fixation. The movable slot 8 is controlled to slide by the slot drive assembly 9. When the slot drive assembly 9 drives the movable slot 8 to move closer to the fixed slot 7, the snap-fit ​​area 5 shrinks to clamp the lamp holder 4. When it moves in the opposite direction, it releases the lamp holder 4, which enables the quick installation and removal of the navigation light assembly 3.

[0037] Specifically, combining Figures 1-5 As shown, the card holder drive assembly 9 includes a fixed base 10, on which a sliding groove 11 adapted to the movable card holder 8 is provided. A sliding guide structure 12 is provided between the movable card holder 8 and the fixed base 10. An automatic return structure 13 is also provided between the movable card holder 8 and the fixed base 10, which can always provide a force to the outer end of the sliding groove 11 when the movable card holder 8 slides to the inner end of the sliding groove 11.

[0038] The movable bracket 8 is slidably connected in the sliding groove 11 of the fixed base 10. When installing or removing the navigation light assembly 3, the movable bracket 8 is manually pushed into the sliding groove 11 to expand the locking area 5, making it easier to insert or release the lamp holder 4. The sliding guide structure 12 between the movable bracket 8 and the fixed base 10 guides the sliding of the movable bracket 8, ensuring accurate movement path and preventing jamming. The automatic return structure 13 can reset the movable bracket 8 to the initial position without external force, that is, it can make the movable bracket 8 move closer to the fixed bracket 7 to clamp the lamp holder 4. The fixing operation of the lamp holder 4 is convenient and can achieve quick installation and removal.

[0039] Specifically, combining Figure 4 and Figure 5 As shown, the sliding guide structure 12 includes a guide slide rod 14 connected to the movable card seat 8, and a guide slide hole 15 connected to the sliding groove 11 is provided on the outer end of the fixed seat 10, with the guide slide rod 14 passing through the guide slide hole 15.

[0040] The guide slide rod 14 passes through the guide slide hole 15 of the fixed base 10 and slides with the guide slide hole 15, which can guide the movable card seat 8 to slide in a straight line, play a guiding role for the movable card seat 8, ensure accurate movement path, and prevent jamming.

[0041] Specifically, combining Figure 4 and Figure 5As shown, the automatic return structure 13 includes a return spring 16 sleeved on the guide slide rod 14 and located in the sliding groove 11. The two ends of the return spring 16 abut against the outer end of the movable card seat 8 and the inner wall of the guide slide hole 15, respectively.

[0042] One end of the return spring 16 abuts against the movable bracket 8, and the other end abuts against the inner wall of the guide slide hole 15. When an external force pushes the movable bracket 8 to compress the return spring 16, the return spring 16 stores energy. When the external force disappears, the return spring 16 rebounds, causing the movable bracket 8 to return to the fixed bracket 7 to clamp the lamp holder 4. The lamp holder 4 is easy to install and is securely fixed.

[0043] The return spring 16 provides a stable return force, ensuring reliable clamping and release actions, and requires no additional power source, resulting in a compact structure.

[0044] Specifically, combining Figures 2-5 As shown, the guide slide rod 14 is provided with a stroke limiting structure 17 at its outer end. The stroke limiting structure 17 includes a limiting ring 18 sleeved on the guide slide rod 14 and located outside the sliding groove 11. The guide slide rod 14 is provided with a groove 19 adapted to the limiting ring 18 at its outer end.

[0045] The limiting ring 18 is embedded in the groove 19 of the guide slide rod 14. When the guide slide rod 14 moves to the point where the ring contacts the outer wall of the fixed seat 10, the sliding stops to prevent the moving seat 8 from coming out of the sliding groove 11. The mechanical limiting has high reliability and is not affected by environmental factors. It can avoid excessive displacement that could damage the mechanism and ensure that the clamping range is always within a safe range. The detachable design of the ring 18 makes maintenance convenient.

[0046] Specifically, combining Figures 2-5 As shown, the inner end of the card holder 2 is provided with an inverted L-shaped insert 20. The entry end of the insert 20 is provided with an easy-entry chamfer 21, and the right angle of the insert 20 is also provided with an arc chamfer 22.

[0047] The locking part 20 contacts the top and side wall of the lamp holder 4 to form a bidirectional limiting. The inverted L-shaped locking part 20 can prevent the lamp holder 4 from jumping up and down and shifting horizontally, making it suitable for vibration environments and enhancing the stability of the lamp holder 4.

[0048] The easy-to-access chamfer 21 can guide the lamp holder 4 to slide into the insert 20; the rounded chamfer 22 can reduce stress concentration and prevent the insert 20 from breaking.

[0049] Specifically, combining the diagram and Figure 2 As shown, the fixed base plate 1 is detachably connected to the apron deck. The fixed base plate 1 is provided with several bolt holes 23 that are adapted to the apron deck, and fixing bolts are inserted into the bolt holes 23.

[0050] The fixed base plate 1 is detachably connected to the apron deck by fixing bolts. The fixed base plate 1 is firmly fixed, easy to disassemble and assemble, and easy to maintain.

[0051] The working principle of this utility model is as follows: When installing the navigation light assembly 3, first manually push the movable bracket 8 into the sliding groove 11 to expand the locking area 5, then put in the mounting lamp holder 4, and then remove the external force pushing. The return spring 16 rebounds and makes the movable bracket 8 return to the fixed bracket 7 to clamp the mounting lamp holder 4 to complete the fixed installation; when disassembling the navigation light assembly 3, the external force pushes the movable bracket 8 to slide into the sliding groove 11 to release the mounting lamp holder 4.
