Description

Technical Field

[0001] This utility model relates to the field of garage door technology, and in particular to garage door guide rails. Background Technology

[0002] In the early days, simple garage doors might have been just a wooden or metal plate mounted directly onto the doorway, opened and closed using simple hinges or pulleys. This method had many problems. For example, without the guidance of guide rails, the door was prone to shifting during movement, especially heavier wooden or iron doors, which had extremely poor stability.

[0003] The evolution of garage door technology from manual to electric has placed new demands on guide rails. With advancements in motor and transmission technologies, methods such as sprocket and chain drives, belt and pulley drives are being applied to garage door systems. Guide rails need to work in conjunction with these transmission systems to ensure efficient power transmission. For example, in sprocket-chain driven garage doors, the internal structure of the guide rail needs to be designed to accommodate and guide the chain's movement, ensuring that the chain drives the door to open and close smoothly within the guide rail.

[0004] However, the noise generated by traditional garage door sprocket chains is amplified in this enclosed environment, producing high-frequency vibrations that generate noise and create a more noticeable auditory experience for users. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a garage door guide rail, which aims to improve the problem that the noise generated by the garage door sprocket chain in the prior art is amplified in such a closed environment, resulting in high-frequency vibration and noise, which brings more obvious auditory experience to users.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a garage door guide rail, comprising a guide rail, a connecting plate disposed inside the guide rail, a mounting plate disposed outside the connecting plate, a bolt disposed inside the connecting plate, a spring disposed outside the bolt, one end of the spring being fixedly connected to the outside of the connecting plate, the other end of the spring being fixedly connected to the outside of the mounting plate, a nut being threadedly connected to the outside of the bolt, the outside of the nut abutting against the outside of the mounting plate, and a transmission assembly disposed inside the mounting plate for driving the sliding seat to move.

[0007] Furthermore, the transmission assembly includes a first sprocket, which is rotatably connected inside the fixed plate. The first sprocket is connected to a second sprocket via a leather chain, and locking blocks are provided on the outer ends of the leather chain.

[0008] Furthermore, the engaging block is disposed inside the sliding seat.

[0009] Furthermore, the sliding seat is slidably connected inside the guide rail.

[0010] Furthermore, a mounting bracket is fixedly connected to the top of the guide rail.

[0011] Furthermore, a positioning plate is fixedly connected to the bottom of the sliding seat.

[0012] Furthermore, the leather chain is disposed inside the guide rail.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the cooperation between the bolts and springs in the guide rail system ensures that the garage door runs smoothly in the guide rail, maintaining the balance and stability of the door. The bolts fix the position of the springs, preventing them from shifting or loosening during operation, while the springs provide appropriate elasticity, allowing the door to open and close smoothly and without obstruction.

[0015] 2. In this utility model, the garage door motor drives the second sprocket to rotate, which in turn drives the chain and the first sprocket to rotate. The two sets of sprockets position the leather chain, ensuring that it moves in the effective position without deviation. In addition, the leather chain is made of non-steel material, reducing chain noise. As the chain moves, it drives the engaging locking block to move, which in turn drives the sliding seat to move. The connecting arm is connected to the positioning plate at the bottom of the movable seat, and the connecting arm drives the garage door to move. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1-5 An embodiment of this utility model provides a garage door guide rail, including a guide rail 1. A connecting plate 5 is provided inside the guide rail 1, and an mounting plate 4 is provided outside the connecting plate 5. A bolt 7 is provided inside the connecting plate 5, and a spring 6 is provided outside the bolt 7. One end of the spring 6 is fixedly connected to the outside of the connecting plate 5, and the other end of the spring 6 is fixedly connected to the outside of the fixing plate 8. A nut 9 is threadedly connected to the outside of the bolt 7, and the outside of the nut 9 abuts against the outside of the fixing plate 8. A transmission assembly is provided inside the fixing plate 8. The transmission assembly is used to drive the sliding seat 12 to move. The transmission assembly includes a first sprocket 2, which is rotatably connected inside the fixing plate 8. The first sprocket 2 is connected to a second sprocket 11 through a leather chain 3. The two ends of the leather chain 3 are provided with locking blocks 13.

[0025] Bolt 7 passes through connecting plate 5, and nut 9 is attached to its exterior. Nut 9 abuts against fixing plate 8, thus forming a stable connection structure. This structure prevents spring 6 from shifting when subjected to various forces, such as vibrations generated by door movement or the elastic reaction of spring 6 itself. The movement of the entire garage door begins with the garage door motor, which drives sprocket 11 to rotate, thus initiating subsequent transmission actions. Utilizing the motor as a power source, the foundation for automated garage door drive is achieved, facilitating user operation of opening and closing the garage door. After sprocket 11 rotates, the power is transmitted to sprocket 2 via leather chain 3, causing sprocket 2 to rotate as well. This combination of sprockets and chain is a common and effective mechanical transmission method. The two sets of sprockets work together to position the leather chain 3, ensuring that the leather chain 3 always runs in the pre-set effective position during movement, avoiding deviation, thus ensuring the stability and accuracy of the entire transmission process, allowing the garage door to move smoothly along the predetermined trajectory. When the leather chain 3 moves, the locking blocks 13 set on the outside of its two ends engage with the sliding seat 12 inside, and the movement of the chain will drive the locking blocks 13 to move synchronously, thereby causing the sliding seat 12 to move along the guide rail 1. This is the key link in converting the rotational motion of the chain into the linear motion of the sliding seat 12.

[0026] Reference Figure 1 , Figure 2 and Figure 4 The locking block 13 is located inside the sliding seat 12, which is slidably connected to the inside of the guide rail 1. The top of the guide rail 1 is fixedly connected to the mounting bracket 10, and the bottom of the sliding seat 12 is fixedly connected to the positioning plate 14. The leather chain 3 is located inside the guide rail 1.

[0027] A mounting bracket 10 is fixedly connected to the top of the guide rail 1. The mounting bracket 10 facilitates the installation and fixation of the entire garage door guide rail 1 to the garage wall or other supporting structure, providing convenience for the stable installation of the guide rail 1 and ensuring that it can normally bear various forces when the garage door is running. The positioning plate 14 fixedly connected to the bottom of the sliding seat 12 is connected to the connecting arm. When the sliding seat 12 moves, this displacement is transmitted to the garage door through the connecting arm, which ultimately drives the garage door to open or close accordingly, realizing the overall movement function of the garage door and completing the transmission of the entire drive and transmission link.

[0028] Working Principle: When using this device, the motor drives the second sprocket 11 to rotate, which in turn drives the leather chain 3 and the first sprocket 2 to rotate. The cooperation of the two sets of sprockets effectively positions the leather chain 3, ensuring its smooth operation in the correct position and preventing deviation. The leather chain 3 is made of non-steel material, which significantly reduces chain noise. As the chain moves, the locking block 13 moves accordingly, pushing the sliding seat 12 to slide. The positioning plate 14 at the bottom of the sliding seat 12 is connected to the connecting arm, which in turn drives the garage door to complete a smooth opening and closing movement. The cooperation of the bolt 7 and the spring 6 in the guide rail 1 system ensures that the garage door runs smoothly in the guide rail 1, maintaining the balance and stability of the door. The bolt 7 fixes the position of the spring 6, preventing the spring 6 from shifting or loosening during operation, while the spring 6 provides appropriate elasticity, allowing the door to open and close smoothly without obstruction.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
