Technical Field
[0001] This utility model relates to the field of curtain track technology, specifically a durable, rust-proof, and smooth curtain track. Background Technology
[0002] Curtain tracks are curtain accessories used to hang curtains so that they can open and close, and also to enhance the beauty of the curtain fabric. As the material and spiritual living standards of the general public improve, the demand for quiet curtain tracks is also increasing. Based on this, a silent strip installation structure for curtain tracks has been designed.
[0003] Existing technology achieves a silent effect by engaging a sound-absorbing strip with the curtain track and having a pulley contact the strip. However, existing sound-absorbing strips are typically inserted from one side into straight curtain tracks, limiting their applicability. Furthermore, the installation and removal of the sound-absorbing strips are inconvenient. To address these shortcomings, a sound-absorbing strip installation structure for curtain tracks disclosed in existing technology (Chinese patent application number CN219538007U, publication date August 18, 2023) can be referenced. This device, when the curtain track is straight, first securely installs the curtain track, and then... The sound-absorbing strip is inserted from one side. Alternatively, you can use needle-nose pliers or your hand to press the sound-absorbing strip into the locking block to complete the installation process. When the curtain track is curved, first install the sound-absorbing strip on the straight section, similar to the installation of the straight curtain track. When installing at the bend of the curved curtain track, you can divide the sound-absorbing strip into small pieces and press each small piece into the locking block at the bend using needle-nose pliers or your hand. By installing multiple sections of sound-absorbing strip in sequence, you can achieve silent sliding of the pulley. This method is suitable for curved curtain tracks. When you need to disassemble, simply remove the sound-absorbing strip from the locking block using needle-nose pliers or your hand. Disassembly is also very convenient.
[0004] However, while the device solves the problems of narrow installation range and inconvenient disassembly of the soundproof strip, it still has certain limitations in other aspects. First, after a period of use, the surface of the soundproof strip will inevitably be scratched or even damaged due to long-term friction and friction with the pulley. These marks will increase the wear and tear on the pulley, reduce its service life, and may cause the pulley to jam during daily use, affecting the smoothness of the pulley's movement.
[0005] Therefore, we proposed a durable, rust-resistant, and smooth curtain track that can effectively solve the above problems. Utility Model Content
[0006] The purpose of this invention is to provide a durable, rust-proof, and smooth curtain track to solve the problem mentioned in the background art where the soundproof strip and the pulley surface rub against each other after long-term use, affecting the smoothness of the pulley's movement and reducing its service life.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a durable and rust-proof smooth curtain track, comprising a curtain track, wherein two sets of sound-absorbing strips are symmetrically snapped onto the inner wall of the curtain track, and a slider is slidably mounted on the upper surface of the sound-absorbing strips. The outer walls on both sides of the slider are rotatably connected to pulleys that contact the upper surface of the sound-absorbing strips, and the slider is provided with a lubrication mechanism for reducing the friction of the upper surface of the sound-absorbing strips.
[0008] The lubrication mechanism includes a storage cavity inside the slider for storing lubricant. Two sets of guide grooves for lubricant to flow out are opened through the inner walls of the storage cavity on both sides near the pulley. A guide tube is opened through the inner wall of the storage cavity downward. A ball joint is slidably installed on the inner wall of the guide groove. A baffle for adjusting the opening and closing state of the limit block is fixed on the outer wall of the ball joint near the pulley. An elastic element for providing reset power to the ball joint is sleeved on the outer wall of the ball joint.
[0009] The pulley is fixed with a drive mechanism on the outer wall near the slider to drive the two sets of limit blocks to reciprocate opening and closing.
[0010] As a preferred technical solution of this application, the inner wall of the guide groove is fixed with a limiting block for limiting the ball head rod. The baffle is in the shape of a truncated pyramid and is fitted with the outer wall of the slider. The two outer walls of the slider are provided with grooves of matching size and shape at the contact positions with the baffle.
[0011] As a preferred technical solution of this application, a limiting block is fixed to the outer wall of the end of the ball head rod away from the baffle, and the two ends of the elastic element are respectively fixed to the limiting block and the limiting ring. Guide hoppers are fixed to both outer walls of the slider and below the two sets of guide groove ports.
[0012] As a preferred technical solution of this application, a one-way interface is sealed and installed on the bottom inner wall of the material guide tube near the opening position, and the bottom cross-sectional shape of the inner wall of the storage cavity is arched.
[0013] As a preferred technical solution of this application, the driving mechanism includes a connecting ring fixed to the outer wall of the two sets of pulleys near the slider. The outer wall of the connecting ring near the slider is provided with a groove, and the ball end of the ball head rod is slidably connected to the smooth end face of the connecting ring and the groove.
[0014] As a preferred technical solution of this application, the outer walls on both sides of the slider are also fixed with a cleaning mechanism for cleaning the oil stains on the upper surface of the silent strip. The cleaning mechanism includes a pull-out frame installed on the front surface of the slider. The upper surface of the pull-out frame is set as an inclined surface. A chip collection box is slidably installed inside the pull-out frame. Two sets of scraper teeth are symmetrically fixed on the outer walls on both sides of the slider.
[0015] As a preferred technical solution of this application, the cross-sectional shape of the shovel teeth in the top view is an inverted "V" shape, and two sets of hooks for connecting curtains are symmetrically fixed on the lower surface of the slider.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: First, the groove in the drive mechanism rotates. When the groove rotates to the ball head rod position, the elastic element rebounds and resets, driving the ball head rod and the baffle to extend outward. At this time, the baffle disengages from the groove, and the lubricant falls along the guide groove and the guide hopper onto the upper surface of the soundproof strip. After the groove separates from the ball head rod, the ball head rod is squeezed and retracted, and the elastic element is stretched to prepare for the baffle to open next time. The intermittently dripping lubricant lubricates the surface of the pulley and the soundproof strip, reducing the friction between the pulley and the soundproof strip, reducing wear, preventing jamming, and improving the smoothness of the pulley in the curtain track. At the same time, the curtain track is made entirely of aluminum alloy, which has rust resistance and a certain structural strength, and is durable.
[0017] Secondly, when the groove rotates to the ball head rod position, the elastic element rebounds and resets, causing the ball head rod and baffle to extend outward, thereby automatically opening the guide groove. When the groove separates from the ball head rod, the ball head rod is squeezed and retracted, and the elastic element is stretched to prepare for the baffle to open next time, ultimately achieving the effect of intermittently and automatically opening the guide groove.
[0018] Furthermore, as the slider moves, the scraper teeth will fit against the upper surface of the soundproof strip and clean the oil stains on the upper surface of the soundproof strip, removing the oil stains accumulated on the upper surface of the soundproof strip. Then, the scraper teeth's "eight"-shaped structure and serrations will be used to guide the scraped oil debris into the debris collection box for centralized collection, preventing oil debris from staining the curtains.

[0026] 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.
[0027] Example 1: To address the issue of scratches and friction between the silencer strip 11 and pulley 21 after long-term use, which increases friction and affects the smoothness of pulley 21's movement, please refer to the attached document. Figure 1 - Appendix Figure 6 The present invention provides the following technical solution: a durable and rust-proof smooth curtain track, including a curtain track 1, wherein two sets of sound-absorbing strips 11 are symmetrically snapped into the inner wall of the curtain track 1, and a slider 2 is slidably installed on the upper surface of the sound-absorbing strips 11. The outer walls of the two sides of the slider 2 are rotatably connected to pulleys 21 that contact the upper surface of the sound-absorbing strips 11. The slider 2 is provided with a lubrication mechanism for reducing the friction of the upper surface of the sound-absorbing strips 11.
[0028] The lubrication mechanism includes a storage cavity 24 inside the slider 2 for storing lubricant. Two sets of guide grooves 241 for lubricant to flow out are provided through the inner walls of the storage cavity 24 near the pulley 21. A guide tube 243 is provided through the inner wall of the storage cavity 24 downward. A ball joint rod 25 is slidably installed on the inner wall of the guide groove 241. A baffle 26 for adjusting the opening and closing state of the limit block 242 is fixed on the outer wall of the ball joint rod 25 near the pulley 21. An elastic element for providing reset power to the ball joint rod 25 is sleeved on the outer wall of the ball joint rod 25. A drive mechanism for driving the two sets of limit blocks 242 to reciprocate opening and closing is fixed on the outer wall of the pulley 21 near the slider 2.
[0029] The inner wall of the guide groove 241 is fixed with a limiting block 242 for limiting the ball head rod 25. The baffle 26 is in the shape of a truncated pyramid and is fitted with the outer wall of the slider 2. The two outer walls of the slider 2 are provided with grooves of matching size and shape at the contact positions with the baffle 26. The outer wall of the ball head rod 25 away from the baffle 26 is fixed with the limiting block 242, and the two ends of the elastic element are fixed with the limiting block 242 and the limiting ring, respectively. The two outer walls of the slider 2 are fixed with guide hoppers 28 below the ports of the two sets of guide grooves 241. The bottom inner wall of the guide tube cavity 243 is sealed with a one-way interface near the opening. The bottom cross-sectional shape of the inner wall of the storage cavity 24 is arched.
[0030] First, the groove 271 in the drive mechanism rotates. When the groove 271 rotates to the position of the ball head rod 25, the elastic element rebounds and resets, causing the ball head rod 25 and the baffle 26 to extend outward. At this time, the baffle 26 disengages from the groove, and the lubricant falls along the guide groove 241 and the guide hopper 28 onto the upper surface of the silent strip 11. After the groove 271 separates from the ball head rod 25, the ball head rod 25 is squeezed and retracted, and the elastic element is stretched to prepare for the baffle 26 to open next time. The intermittently dripping lubricant lubricates the surface of the pulley 21 and the silent strip 11, reducing the friction between the pulley 21 and the silent strip 11, reducing wear, extending the service life of the pulley 21, preventing the pulley 21 from jamming, and improving the smoothness of the pulley 21 in the curtain track 1. At the same time, the curtain track 1 is made of aluminum alloy, which is rust-resistant and has a certain structural strength, making it durable.
[0031] Example 2: Based on Example 1, a drive mechanism for reciprocating opening and closing of the ball joint 25 and the baffle 26 in the lubrication mechanism is also disclosed. See attached diagram. Figure 2 - Appendix Figure 6 The specific structure is as follows: The driving mechanism includes a connecting ring 27 fixed to the outer wall of the two sets of pulleys 21 near the slider 2. The outer wall of the connecting ring 27 near the slider 2 is provided with a groove 271, and the ball end of the ball head rod 25 is slidably connected to the smooth end face of the connecting ring 27 and the groove 271.
[0032] First, when the groove 271 rotates to the position of the ball head rod 25, the elastic element rebounds and resets, causing the ball head rod 25 and the baffle 26 to extend outward, thereby automatically opening the guide groove 241. When the groove 271 separates from the ball head rod 25, the ball head rod 25 is squeezed and retracted, and the elastic element is stretched to prepare for the baffle 26 to open next time, ultimately achieving the effect of intermittently and automatically opening the guide groove 241.
[0033] Example 3: Based on Examples 1 and 2, a cleaning mechanism for scraping off dried oil stains on the upper surface of the soundproof strip 11 is also disclosed. (See attached diagram.) Figure 2 - Appendix Figure 3The specific structure is as follows: the outer walls on both sides of the slider 2 are also fixed with a cleaning mechanism for cleaning the oil stains on the upper surface of the silent strip 11. The cleaning mechanism includes a pull-out frame installed on the front surface of the slider 2. The upper surface of the pull-out frame is set as an inclined surface. A chip collection box 23 is slidably installed inside the pull-out frame. Two sets of shovel teeth 22 are symmetrically fixed on the outer walls on both sides of the slider 2.
[0034] The cross-sectional shape of the shovel teeth 22 in the top view is an inverted "V" shape, and two sets of hooks 3 for connecting curtains are symmetrically fixed on the lower surface of the slider 2.
[0035] First, when the slider 2 moves, the scraper teeth 22 will fit against the upper surface of the soundproof strip 11 and clean the oil stains on the upper surface of the soundproof strip 11, removing the oil stains accumulated on the upper surface of the soundproof strip 11. Then, using the "eight" shaped structure and serrations of the scraper teeth 22, the scraped oil shavings are concentrated and guided into the shavings collection box 23 for centralized collection, preventing oil shavings from staining the curtains.
