Description

Technical Field

[0001] The present invention relates to the technical field of curtain tracks, and in particular to a three-track-in-one curtain track and assembly. Background Art

[0002] Curtains are a common indoor decorative item that provides shade, decoration, and light regulation. They are widely used in homes and offices. Traditional curtain tracks can only hold one layer of curtains, which cannot meet the needs of users to use multiple layers of curtains in the same space.

[0003] After searching, the Chinese patent with announcement number CN118614749A discloses a three-track-in-one curtain track and assembly, including a track, a sealing member, a mounting code, a roller, and a pulley. The track is a one-track three-groove arrangement with openings at both ends of the track. The openings are connected to two roller grooves and one pulley groove. Two roller grooves are arranged in the middle of the track. The two roller grooves are polygonal side channel structures extending along the length of the track. The outer side channels of the two roller groove polygonal side channel structures are respectively provided with notches extending along the length of the track. The notches of the two roller grooves are horizontally symmetrical reverse notches. Four of the side channels of the two roller groove polygonal side channel structures are respectively used for the four wheels of the roller to fit and press and roll. The multiple rollers are respectively arranged at intervals along the two roller grooves. A Pulley groove, the bottom surface of the pulley groove is provided with a notch extending along the length of the track, the multiple pulleys are arranged at intervals along the pulley groove, the sealing member for closing the openings at both ends of the track is composed of a main head, a secondary head, and a connecting member, and mounting code card slots are provided on both sides of the top of the track; the above scheme adopts a one-track three-slot design, that is, three track grooves are opened on one track, which are used to hang different types of curtains respectively. The outer track groove is used to hang ordinary curtains, which are mainly used for decoration and basic shading functions. The middle track groove is used to hang window screens. The window screens have a certain degree of light transmittance and can provide soft light during the day while maintaining a certain degree of privacy. The inner track groove is used to hang sunshade curtains. The sunshade curtains have good shading performance and can provide complete shading effect when needed. However, the above scheme still has shortcomings in actual use:

[0004] In the daily use of curtains, users often apply a downward force on the curtains when pulling them. This force will be transmitted to the curtain track through the pulley ring connected to the curtains. When a large force is applied for a long time, the friction between the track and the pulley ring will gradually increase, which will lead to increased wear of the track and related components. Over time, this frequent friction may cause the track to deform and be damaged, affecting the normal use of the curtains. Summary of the Invention

[0005] The present invention provides a three-track-in-one curtain track and assembly, which solves the problems of wear, deformation and damage of curtain tracks caused by frequent friction during long-term use in the related art.

[0006] In order to achieve the above-mentioned object, the present invention provides the following technical solutions: a three-track-in-one curtain track, comprising a track body;

[0007] The rail body is provided with three T-shaped sliding grooves along its length direction, and two assembly plates are symmetrically mounted on the rail body.

[0008] A three-in-one curtain track assembly adopts the above-mentioned three-in-one curtain track, including a T-shaped slider, an elastic suspension assembly, a rolling lubricating component and an oil injection assembly;

[0009] A plurality of T-shaped sliders are slidingly arranged in the T-shaped slide groove, a cavity is opened in the T-shaped slide groove, the elastic suspension component is installed in the cavity, and the bottom end of the elastic suspension component slides through the bottom of the T-shaped slide groove, and two rolling lubricating parts that slide with the T-shaped slide groove are symmetrically installed on the T-shaped slide groove. The oil injection component is installed in the cavity above the elastic suspension component and is connected to it, and is respectively communicated with the two rolling lubricating parts; when the elastic suspension component is subjected to tension to drive the T-shaped slide groove to slide in the T-shaped slide groove, the oil injection component is pulled by the elastic suspension component to inject oil into the rolling lubricating part, and then discharged into the T-shaped slide groove through it.

[0010] Preferably, the elastic suspension assembly includes a fixed block, an elastic member and a suspension member, the fixed block is installed in the middle of the cavity, the suspension member is installed at the bottom of the fixed block through the elastic member, and the suspension member slides through the bottom of the T-shaped slider.

[0011] Preferably, the elastic part includes a loading block, a limiting rod and a spring. The loading block is arranged below the fixed block. Limiting rods that slide through the fixed block are installed on all four sides of the loading block. A spring is sleeved on the limiting rod, and the two ends of the spring are respectively connected to the fixed block and the loading block. The suspension part is installed at the bottom of the loading block, and the oil injection assembly is connected to the loading block.

[0012] Preferably, the suspension member includes a suspension rod connected to the bottom of the loading block, and the bottom end of the suspension rod slides through the bottom of the T-shaped slider and is installed with a suspension ring.

[0013] Preferably, the oil filling assembly includes an oil filling cylinder, which is installed in the cavity and located above the fixed block. A piston is installed in the oil filling cylinder, and the piston slides through the oil filling cylinder, the fixed block and is connected to the loading block. Lubricating oil is provided in the oil filling cylinder, an air hole is opened at the top of the oil filling cylinder, and two oil filling pipes are symmetrically connected to the bottom of the oil filling cylinder, and the two oil filling pipes are respectively connected to two rolling lubrication parts.

[0014] Preferably, the piston member includes a piston body, which is slidably arranged in the oil filling cylinder, and a piston rod is installed at the bottom of the piston body. The bottom end of the piston rod slides through the bottom of the oil filling cylinder, the bottom of the fixed block and is connected to the loading block.

[0015] Preferably, a valve is installed on the oil filling pipe, and the valve controls the amount of oil injected into the rolling lubricating component.

[0016] Preferably, the oil filling cylinder is provided with an oil inlet shaft connected to the interior thereof, and the oil inlet shaft is provided with a sealing plug.

[0017] Preferably, the rolling lubrication part includes a lubrication block, and two lubrication blocks that slide in cooperation with the T-shaped groove are symmetrically installed on the T-shaped slider. An oil drain chamber is provided in the lubrication block, and the two oil filling pipes are respectively connected to the oil drain chambers in the two lubrication blocks. A ball that rolls in cooperation with the T-shaped groove is rollingly installed on the bottom of the lubrication block, and the ball extends into the oil drain chamber.

[0018] The beneficial effects of the present invention are:

[0019] 1. The present invention hangs the hook on the curtain on the bottom of the elastic suspension assembly on the T-shaped slider. When the curtain is drawn, the elastic suspension assembly drives the T-shaped slider to slide in the T-shaped slot provided on the track body. Since the elastic suspension assembly has a certain elasticity, the downward pressure generated when the curtain is drawn can be elastically deformed and buffered by the elastic suspension assembly, thereby effectively reducing the direct impact of the downward pressure on the track body. This can reduce the friction between the track body and the T-shaped slider, reduce the wear of the track body and related components, extend the service life of the track body, avoid the situation where the curtain cannot be used normally due to deformation or damage of the track body, and provide users with a more stable and reliable curtain use experience.

[0020] 2. When the curtain is drawn, the elastic suspension assembly is deformed by force, which causes the oil filling assembly to be pulled by the elastic suspension assembly, driving the piston to move downward in the oil filling cylinder. The lubricating oil in the oil filling cylinder can be guided through the oil filling pipe to the rolling lubricating member that slides with the T-shaped slide groove, and then discharged into the T-shaped slide groove through the rolling lubricating member to play a lubricating role. This automatic lubrication mechanism can effectively reduce the friction coefficient between the track body and the T-shaped slider, reducing friction loss. During long-term use, this continuous lubrication effect can further reduce the wear of the track body and related components, ensuring that the curtain can slide smoothly, avoiding problems such as difficulty in pulling the curtain and jamming due to excessive friction, thereby improving the performance and reliability of the curtain and reducing the cost of frequent replacement of the track body and related components due to friction loss, bringing users a more convenient and economical use experience.

[0021] 3. The present invention provides a valve on the oil filling pipe, which can control the lubricating oil guided to the rolling lubricating parts as needed. By adjusting the opening of the valve, the user can accurately control the flow of the lubricating oil, thereby achieving on-demand lubrication. When the curtains are used frequently and friction is more frequent, the valve opening can be appropriately increased to increase the supply of lubricating oil to better lubricate the track body and T-shaped slider and reduce wear. When the curtains are used less frequently, the valve opening can be reduced to reduce the waste of lubricating oil. This design of accurately controlling the amount of lubricating oil can not only ensure that the track and T-shaped slider are always in a good lubricated state, thereby improving the service life and performance of the curtains, but also avoid excessive waste of lubricating oil, save resources, and also reduce problems such as track pollution caused by excessive lubricating oil.

[0033] The following will clearly and completely describe the technical solutions of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] according to Figures 1 to 9 As shown, a three-track-in-one curtain track includes a track body 1;

[0035] The track body 1 is provided with three T-shaped slots 101 along its length, and two assembly plates 102 are symmetrically mounted on the track body 1 .

[0036] The design of the three T-shaped slides 101 of the present invention makes it possible to mount different types of curtains. The outer T-shaped slides 101 can be used to mount ordinary decorative curtains, the middle one is used for window screens, and the inner one is used to mount sunshade curtains, meeting the user's needs of using multiple layers of curtains in the same space. The symmetrically installed assembly plates 102 can stably fix the track body 1 in the installation position, ensuring the stability of the entire curtain track system and avoiding shaking or falling during use.

[0037] like Figure 2 、 Figure 3 and Figure 4 As shown, a three-track-in-one curtain track assembly adopts the above-mentioned three-track-in-one curtain track, including a T-shaped slider 2, an elastic suspension assembly 3, a rolling lubricating component 4 and an oil injection assembly 5;

[0038] A plurality of T-shaped sliders 2 are slidingly arranged in the T-shaped slide groove 101, a cavity 21 is opened in the T-shaped slider 2, the elastic suspension component 3 is installed in the cavity 21, and the bottom end of the elastic suspension component 3 slides through the bottom of the T-shaped slider 2, and two rolling lubricating parts 4 that slide with the T-shaped slide groove 101 are symmetrically installed on the T-shaped slider 2, and the oil injection component 5 is installed in the cavity 21 above the elastic suspension component 3 and connected to it, and is respectively communicated with the two rolling lubricating parts 4; when the elastic suspension component 3 is subjected to tension to drive the T-shaped slider 2 to slide in the T-shaped slide groove 101, the oil injection component 5 is pulled by the elastic suspension component 3 to inject oil into the rolling lubricating part 4, and then discharged into the T-shaped slide groove 101 through it.

[0039] When the curtain is pulled, the tension of the curtain acts on the suspension member 33 of the elastic suspension assembly 3, causing the elastic member 32 to elastically deform, driving the T-shaped slider 2 to slide within the T-shaped chute 101. The elastic deformation of the elastic suspension assembly 3 acts as a buffer, reducing the direct impact of the tension on the track body 1 and the friction between the track body 1 and the T-shaped slider 2, thereby reducing wear on the track body 1 and related components. Simultaneously, when the elastic suspension assembly 3 is deformed under force, the piston member 52 of the oil injection assembly 5 is pulled downward, and the lubricating oil in the oil injection cylinder 51 is injected into the rolling lubricating member 4 through the oil injection pipe 53 and then discharged into the T-shaped chute 101, providing a lubricating effect, further reducing the friction coefficient and ensuring smooth sliding of the curtain.

[0040] like Figure 4 and Figure 5 As shown, in this embodiment, the elastic suspension assembly 3 includes a fixed block 31, an elastic member 32 and a suspension member 33. The fixed block 31 is installed in the middle of the cavity 21, and the suspension member 33 is installed at the bottom of the fixed block 31 through the elastic member 32, and the suspension member 33 slides through the bottom of the T-shaped slider 2.

[0041] The fixing block 31 of the present invention provides a stable installation base for the elastic member 32 and the suspension member 33. When the curtain is subjected to tension, the suspension member 33 drives the spring 323 to stretch or compress through the loading block 321. The limiting rod 322 plays a guiding and limiting role to prevent the spring 323 from deflecting or twisting during the extension and contraction process. The elastic deformation of the spring 323 buffers the tension of the curtain, effectively reduces the impact force on the track body 1, protects the track body 1 and the T-shaped slider 2, and extends their service life.

[0042] like Figure 6As shown, in this embodiment, the elastic member 32 includes a loading block 321, a limiting rod 322 and a spring 323. The loading block 321 is arranged below the fixed block 31. Limiting rods 322 that slide through the fixed block 31 are installed on all four sides of the loading block 321. A spring 323 is sleeved on the limiting rod 322, and the two ends of the spring 323 are respectively connected to the fixed block 31 and the loading block 321. The suspension member 33 is installed at the bottom of the loading block 321, and the oil filling assembly 5 is connected to the loading block 321.

[0043] The loading block 321 serves as a connecting component between the elastic member 32 and the oil injection assembly 5, and plays the role of transmitting force. When the elastic member 32 is subjected to force, the loading block 321 drives the piston member 52 of the oil injection assembly 5 to move, thereby realizing the injection of lubricating oil. The cooperation between the limit rod 322 and the spring 323 not only ensures the normal operation of the elastic member 32, but also further enhances the buffering effect of the pulling force, thereby reducing the wear of the track body 1 and the T-shaped slider 2.

[0044] like Figure 6 As shown, in this embodiment, the suspension member 33 includes a suspension rod 331 , which is connected to the bottom of the loading block 321 . The bottom end of the suspension rod 331 slides through the bottom of the T-shaped slider 2 and is equipped with a suspension ring 332 .

[0045] The suspension rod 331 transmits the tension of the elastic suspension component 3 to the curtain hook, and the hanging ring 332 facilitates the hanging of the curtain hook. When pulling the curtain, the suspension rod 331 and the hanging ring 332 can stably bear the weight and tension of the curtain, and cooperate with the buffering effect of the elastic member 32 to effectively reduce the pressure on the track body 1, thereby ensuring the normal operation of the curtain track system.

[0046] like Figure 4 、 Figure 7 and Figure 8 As shown, in this embodiment, the oil filling assembly 5 includes an oil filling cylinder 51, which is installed in the cavity 21 and is located above the fixed block 31. A piston member 52 is installed in the oil filling cylinder 51, and the piston member 52 slides through the oil filling cylinder 51 and the fixed block 31 and is connected to the loading block 321. Lubricating oil is provided in the oil filling cylinder 51, and an air hole 511 is opened at the top of the oil filling cylinder 51. Two oil filling pipes 53 are symmetrically connected to the bottom of the oil filling cylinder 51, and the two oil filling pipes 53 are respectively connected to the two rolling lubrication parts 4.

[0047] When the elastic suspension component 3 is subjected to force to drive the loading block 321 downward, the loading block 321 drives the piston body 521 to move downward in the oil filling cylinder 51 through the piston rod 522. Due to the existence of the air hole 511, the air in the oil filling cylinder 51 can be discharged smoothly, so that the lubricating oil can be smoothly injected into the rolling lubricating part 4 through the oil filling pipe 53. The lubricating oil lubricates the T-shaped slide groove 101 and the T-shaped slider 2, reduces the friction coefficient, reduces friction loss, and improves the performance and reliability of the curtain.

[0048] like Figure 8 As shown, in this embodiment, the piston member 52 includes a piston body 521, which is slidably arranged in the oil filling cylinder 51, and a piston rod 522 is installed at the bottom of the piston body 521. The bottom end of the piston rod 522 slides through the bottom of the oil filling cylinder 51, the bottom of the fixed block 31 and is connected to the loading block 321.

[0049] The sliding of the piston body 521 in the oil filling cylinder 51 realizes the squeezing and injection of the lubricating oil. The piston rod 522 transmits the displacement of the loading block 321 to the piston body 521, ensuring the normal operation of the oil filling assembly 5. Through the coordinated action of the piston body 521 and the piston rod 522, the injection amount of the lubricating oil can be accurately controlled to ensure that the T-shaped slide groove 101 and the T-shaped slider 2 are fully lubricated.

[0050] like Figure 8 As shown, in this embodiment, a valve 531 is installed on the oil filling pipe 53, and the valve 531 controls the amount of oil injected into the rolling lubricating element 4. The provision of valve 531 allows the user to precisely control the amount of lubricating oil directed to the rolling lubricating element 4 based on the frequency of use and friction of the curtain. When the curtain is frequently used, the valve 531 can be opened wider to increase the lubricating oil supply, better lubricating the track body 1 and T-shaped slider 2 and reducing wear. When the curtain is less used, the valve 531 can be opened narrower to avoid lubricating oil waste and reduce track contamination caused by excessive lubricating oil.

[0051] like Figure 7 As shown, in this embodiment, an oil inlet shaft 512 is mounted on the oil filling cylinder 51 and communicates with the interior thereof. A sealing plug 513 is provided on the oil inlet shaft 512. The oil inlet shaft 512 facilitates the addition of lubricating oil to the oil filling cylinder 51. The sealing plug 513 ensures the tightness of the oil filling cylinder 51. When the lubricating oil in the oil filling cylinder 51 is insufficient, the sealing plug 513 is opened and lubricating oil is added through the oil inlet shaft 512, ensuring that the oil filling assembly 5 can continue to operate normally and provide lubrication for the track body 1 and the T-shaped slider 2.

[0052] like Figure 2 and Figure 9As shown, in this embodiment, the rolling lubricating component 4 includes a lubricating block 41. Two lubricating blocks 41 that slide in cooperation with the T-shaped slide groove 101 are symmetrically installed on the T-shaped slider 2. An oil drain chamber is provided in the lubricating block 41. Two oil filling pipes 53 are respectively connected to the oil drain chambers in the two lubricating blocks 41. A ball 42 that rolls in cooperation with the T-shaped slide groove 101 is rollingly installed at the bottom of the lubricating block 41, and the ball 42 extends into the oil drain chamber.

[0053] The oil drain chamber in the lubrication block 41 is used to store and transport lubricating oil. The ball 42 rolls in the T-shaped groove 101, reducing the friction between the T-shaped slider 2 and the T-shaped groove 101. When the oil injection assembly 5 injects the lubricating oil into the oil drain chamber, the lubricating oil can cover the surface of the ball 42, further reducing the friction coefficient, making the T-shaped slider 2 slide more smoothly in the T-shaped groove 101, and reducing the wear of the track body 1 and the T-shaped slider 2.

[0054] It should be noted that during routine maintenance, regularly check whether the track body 1 is firmly installed, check whether the screws connecting the assembly plate 102 to the wall or ceiling are loose, and tighten them in time if they are loose, and check the sliding condition of the T-shaped slider 2 in the T-shaped slot 101 to observe whether there is any jamming.

[0055] Check the amount of lubricating oil in the oil filling cylinder 51. If the lubricating oil remaining is lower than the preset position of the oil filling cylinder 51, add lubricating oil in time and check whether the regulating function of the valve 531 is normal to ensure that the lubricating oil flow can be flexibly controlled;

[0056] Use a clean soft cloth to wipe the surface of the track body 1 and the T-shaped slider 2 to remove dust and stains. For the rolling lubricating parts 4, use a small amount of detergent to clean the lubricating block 41 and the ball 42, then rinse them with clean water and wipe them dry to ensure their normal rolling and lubricating performance.

[0057] If the spring 323 of the elastic suspension assembly 3 is found to be fatigued or broken, the spring 323 should be replaced in time. If the ball 42 of the rolling lubricating component 4 is severely worn, resulting in uneven sliding, a new ball 42 or the entire rolling lubricating component 4 should be replaced.

[0058] The specific working principle of the present invention is as follows:

[0059] First, select a track body 1 of appropriate length based on the window size and installation location. Use screws or expansion bolts through the mounting holes on the assembly plate 102 to securely mount the track body 1 on the wall or ceiling above the window. Next, install multiple T-shaped sliders 2 in each T-shaped slot 101. During installation, ensure that the T-shaped sliders 2 can slide smoothly within the T-shaped slot 101.

[0060] Then hang the hook on the curtain on the ring 332 of the elastic suspension component 3. When the user pulls the curtain, the tension of the curtain acts on the ring 332 and is transmitted to the loading block 321 through the suspension rod 331, causing the spring 323 of the elastic member 32 to undergo elastic deformation. The deformation of the spring 323 buffers the tension of the curtain, reduces the direct impact on the track body 1, reduces the friction between the track body 1 and the T-shaped slider 2, and protects the track body 1 and the T-shaped slider 2. At the same time, the loading block 321 moves downward, and the piston body 521 is driven to move downward in the oiling cylinder 51 through the piston rod 522. The lubricating oil in the oiling cylinder 51 is released during the activity. Under the squeezing of the plug body 521, the lubricating oil flows to the oil discharge chamber of the rolling lubricating component 4 through the oil filling pipe 53, and the lubricating oil covers the surface of the ball 42, further reducing the friction coefficient between the ball 42 and the T-shaped slide 101, so that the T-shaped slider 2 can slide more smoothly in the T-shaped slide 101. The user can control the flow of the lubricating oil by adjusting the valve 531 on the oil filling pipe 53 according to the frequency of use of the curtain and the smoothness of sliding. When the lubricating oil remaining in the oil filling cylinder 51 is insufficient, open the sealing plug 513 and add lubricating oil to the oil filling cylinder 51 through the oil inlet shaft 512 to ensure that the oil filling component 5 continues to work normally.

[0061] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
