Description

Technical Field

[0001] This utility model relates to the field of concealed track technology, and in particular to a concealed track end cap structure. Background Technology

[0002] In modern architectural decoration, the demand for spatial aesthetics is increasing. Exposed tracks and their end caps can affect the overall decoration style, so concealed tracks are gradually becoming the mainstream trend. For example, in some high-end commercial venues, hotel lobbies, and home decorations, tracks need to be hidden inside the ceiling or walls. Concealed track end caps, as the end sealing components of the track system, need to be installed concealed along with the track to achieve a simple and beautiful overall space. At the same time, in some industrial scenarios, such as rail transport systems in factories, tracks also need to be hidden underground or within specific structures to ensure the flatness of the ground. Concealed track end caps must be able to adapt to this concealed installation method and meet the corresponding load-bearing and usage requirements.

[0003] In practical applications of concealed track systems, existing concealed track end cap structures are prone to noise and component wear due to long-term sliding of pulleys inside the track. At the same time, dust and debris accumulated inside the track can also affect the smoothness of sliding and increase maintenance costs. If traditional solutions need to achieve both buffering and cleaning functions, buffers and cleaning devices often need to be installed at the ends of the track. This not only results in complex structures and large space occupation, but also requires additional power supply or piping, leading to poor compatibility.

[0004] Therefore, a concealed track end cover structure is proposed to address the above problems. Utility Model Content

Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0021] The following detailed description of some embodiments of this application is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0022] In practical applications of concealed track systems, the constant sliding of pulleys inside the track can easily cause noise and component wear due to collisions. Simultaneously, accumulated dust and debris inside the track can affect the smoothness of sliding and increase maintenance costs. Therefore, a concealed track end cover structure integrating both cushioning and automatic cleaning functions has emerged, such as... Figures 1 to 5 As shown, this application provides a concealed track end cap structure, the core of which consists of end cap body 4, reset component 9, telescopic airbag 3 and other components. Through the ingenious design that combines mechanical and pneumatic elements, it effectively solves the pain point of the traditional track end cap having a single function.

[0023] The structure uses the end cap body 4 as the basic carrier, and its front end is stably connected to the concealed track body 7. A telescopic airbag 3, made of highly elastic and aging-resistant material, is installed inside the concealed track body 7 and at the front end of the end cap body 4. This airbag serves as both a buffer and a pneumatic power source. A stop plate 1 is fixed to the front end of the telescopic airbag 3. When the pulley slides to the end of the track, it will first contact the stop plate 1, preventing the pulley from directly impacting the components and causing damage. The top of the telescopic airbag 3 is connected to an air inlet pipe 2, and the bottom is connected to an air outlet pipe 10. Both the air inlet pipe 2 and the air outlet pipe 10 are equipped with one-way ventilation components 8, which can precisely control the airflow direction and prevent backflow. Furthermore, connecting pipes 6 are installed at both the front and rear ends of the concealed track body 7. An air outlet 5 is installed on the side of the connecting pipe 6 closest to the concealed track body 7, and one end of the air outlet 5 extends through the concealed track body 7 into the interior at an angle downwards, allowing the airflow to more accurately sweep away dust inside the track.

[0024] From the workflow perspective, when the pulley slides inside the concealed track body 7 and impacts the abutment plate 1, the abutment plate 1 will cause the telescopic airbag 3 to contract. At this time, the one-way ventilation component 8 in the air inlet pipe 2 will close, and the one-way ventilation component 8 in the air outlet pipe 10 will open. The gas in the telescopic airbag 3 will pass through the air outlet pipe 10 into the connecting pipe 6, and then be discharged through the air outlet head 5, thus blowing away the dust inside the concealed track body 7. Subsequently, under the action of the reset component 9 inside the telescopic airbag 3, the telescopic airbag 3 will re-extend. At this time, the one-way ventilation component 8 in the air outlet pipe 10 will close, and the one-way ventilation component 8 in the air inlet pipe 2 will open under the action of air pressure difference. Outside air will enter the telescopic airbag 3 through the air inlet pipe 2 to complete the gas replenishment, so that the entire structure can repeatedly achieve the buffering and cleaning functions.

[0025] In one optional implementation, the reset component 9 is the core structure for achieving the buffering and reset functions, and its overall design takes into account both mechanical stability and smooth operation. This component consists of a slide groove 94, a reset spring 93, a slider 92, and a reset rod 91. These components are precisely fitted together to form a complete transmission link: the slide groove 94 serves as the basic mounting carrier, with internal space reserved to accommodate the sliding of the slider 92; the reset spring 93 is laterally fixed to the rear end of the slide groove 94, and its front end abuts against the slider 92; the front end of the slider 92 is rigidly connected to the reset rod 91, and its outer contour has a very small gap with the inner wall of the slide groove, ensuring smooth sliding while preventing wobbling; the front end of the reset rod 91 extends through the slide groove to the rear end of the abutment plate 1 and is fixed thereto, forming a force transmission path between the abutment plate, the reset rod, the slider, and the spring.

[0026] When the pulley slides within the concealed track body 7 and impacts the abutment plate 1, the reset assembly 9 enters the buffering phase. The impact force causes the abutment plate 1 to shift backward, simultaneously driving the reset rod 91 to push the slider 92 backward along the slide groove 94. At this time, the slider 92 compresses the reset spring 93, causing it to contract and store energy. Simultaneously, the displacement of the abutment plate 1 triggers the contraction of the telescopic airbag 3, further absorbing the impact force through the compression of the gas inside the airbag, forming a double buffer of spring and airbag, effectively reducing damage to the track and pulley from the impact.

[0027] After the impact force dissipates, the reset assembly 9 enters the automatic reset phase. The reset spring 93 releases its stored elastic potential energy, pushing the slider 92 forward along the slide groove 94. The slider's movement is transmitted to the abutment plate 1 via the reset rod 91, restoring it to its initial position. During this process, the compressed telescopic airbag 3 also re-expands under its own elasticity, and the entire system returns to a standby state, ready for the next possible impact. This design, through the synergy of mechanical structure and elastic elements, achieves both efficient buffering and automatic reset, significantly improving the durability and operational stability of the equipment.

[0028] In one optional embodiment, the one-way ventilation assembly 8 is a key device for ensuring unidirectional gas flow within the inlet pipe 2 and outlet pipe 10. Its structure is precisely designed, and all components work together seamlessly. The vent 81, serving as the core channel for gas flow, is fixedly installed inside the two pipes. Its inner wall precisely matches the rubber plug 85, which is made of a highly elastic material and initially fits tightly into the vent 81, forming a reliable seal. A push rod 83 is connected to one side below the rubber plug 85. The push rod 83 extends axially along the pipe, with one end passing through the pipe wall and extending to the outside, and a limiting plate 82 installed at its end. Simultaneously, a fixing spring 84 is fitted onto the outer wall of the push rod 83. The two ends of this spring are fixed between the rubber plug 85 and the inner wall of the pipe, maintaining a pre-tightened state at all times.

[0029] When directional air pressure appears in the pipeline, the pressure acts on the rubber plug 85, causing it to overcome the elastic force of the fixing spring 84 and disengage from the vent 81. At this time, the vent 81 opens, allowing gas to pass smoothly. Simultaneously, the disengagement of the rubber plug 85 pushes the push rod 83 outward, causing the limiting plate 82 to move away from the pipeline. The fixing spring 84 stores elastic potential energy due to compression. When the air pressure disappears, the reaction force of the fixing spring 84 is quickly released, pushing the rubber plug 85 back to its original position and re-embedding into the vent 81, forming a seal again. The push rod 83 and the limiting plate 82 also return to their initial positions. This cyclical action of pressure-driven conduction and pressureless sealing precisely achieves unidirectional gas flow control, effectively preventing backflow.
