Description

Technical Field

[0001] This utility model relates to RV accessory technology, and in particular to a novel RV window glass strut locking device. Background Technology

[0002] In RV design, the window support system is a crucial component for ensuring ventilation, lighting, and safety within the vehicle. Traditional RV window supports often employ simple telescopic structures, secured by a single locking point or friction plate. This results in insufficient adjustment precision, making it difficult to achieve accurate multi-angle positioning and meet users' refined needs for varying ventilation and lighting levels. Furthermore, the locking mechanisms of existing supports are unstable. During RV operation, external forces such as road bumps and vibrations can easily cause locking failure, leading to accidental glass slippage. This not only affects the user experience but may also cause structural wear and even safety hazards due to glass movement.

[0003] Furthermore, the installation and maintenance of traditional struts are complex. Fixing components often employ welding or integrated designs, requiring disassembly of the entire structure for removal. Replacing vulnerable parts such as springs and telescopic rods is cumbersome, increasing time and labor costs for subsequent maintenance. Additionally, the elastic components of most struts are directly exposed, making them susceptible to corrosion from dust, rain, and ultraviolet radiation over long-term use, leading to elasticity loss and shortened lifespan, further reducing the reliability and durability of the device. Therefore, there is an urgent need for a new strut locking device that enables precise adjustment, stable locking, easy maintenance, and protective functions to address many of the pain points in existing technologies. Utility Model Content

[0004] Purpose of the utility model: The purpose of this utility model is to provide a way to achieve multi-angle precise adjustment of the opening angle of the window glass, improve the stability of the locking mechanism, and avoid the problem of locking failure caused by vibration during the driving of the RV; another purpose of this utility model is to reduce the corrosion of the elastic components by the external environment and extend the service life of the device, thereby solving the shortcomings of traditional support rods in terms of adjustment accuracy, stability, maintenance convenience and durability.

[0005] Technical solution: A novel RV window glass strut locking device includes a movable rod outer sleeve, an inner movable rod slidably connected inside the movable rod outer sleeve, a support ring fixedly connected to the outer side wall of the movable rod outer sleeve, a spring provided on the right side of the support ring, the spring being wound around the outer side of the movable rod outer sleeve, a locking sleeve slidably connected to the right side of the outer side wall of the movable rod outer sleeve, and the left side of the locking sleeve being fixedly connected to the right end of the spring.

[0006] Furthermore, the right side of the movable rod outer sleeve is symmetrically fixedly connected with perforated clips, and each pair of adjacent perforated clips is connected with a claw. The outer side wall of the inner rod of the movable rod is symmetrically provided with multiple engaging grooves.

[0007] Furthermore, both the outer wall of the inner rod of the movable rod and the left end of the outer sleeve of the movable rod are connected to a fixed seat.

[0008] Furthermore, a spring protective sleeve is fixedly connected to the outer wall of the movable rod sleeve on the right side of the support ring.

[0009] Beneficial effects: Utilizing the sliding engagement between the outer and inner rods of the movable rod, along with the multi-position locking design of the claws and engaging grooves, users can flexibly adjust the length by pressing the locking sleeve, achieving precise control of different opening angles of the window glass and fully meeting diverse needs such as ventilation and lighting. The spring limiting the support ring provides continuous restoring force to the locking sleeve, ensuring the claws are tightly embedded in the engaging grooves, effectively resisting vibrations or external impacts during RV movement, preventing accidental slippage of the movable rod, and ensuring the stability of the window glass support. The fixing base achieves quick connection to the window frame and glass frame via bolts; disassembly only requires unscrewing the bolts to remove the entire device. Component disassembly follows the reverse assembly process, facilitating individual replacement of vulnerable parts such as the inner rod and springs, significantly reducing later maintenance costs. The spring protective sleeve effectively encloses the spring on the right side of the support ring, reducing the corrosion of the spring by dust and moisture, extending its service life, and preventing safety hazards caused by exposed springs, thus improving the overall durability of the device.
