Description

Technical Field

[0001] This utility model relates to the field of curtain tracks, and in particular to a silent and smooth curtain track mechanism. Background Technology

[0002] Curtain tracks are devices used to hang curtains and allow them to slide smoothly. They are mostly made of aluminum alloy, stainless steel, or plastic. The tracks are equipped with pulley assemblies or sliders and are connected to the curtains via hooks. The curtains can be opened and closed manually or electrically. They are classified as exposed tracks and concealed tracks according to their installation method, and as straight tracks and curved tracks according to their shape. They are suitable for different types of windows, can fix the position of the curtains, and reduce friction. They are the basic accessories for realizing the function of opening and closing curtains in homes and offices.

[0003] Most existing curtain track mechanisms lack effective noise reduction designs. Simply adding sound-absorbing strips and lubricating grease cannot fundamentally solve the noise problem. In actual use, the significant friction noise generated by the rollers rolling against the track seriously disrupts the quiet indoor environment. Therefore, those skilled in the art have provided a silent and smooth curtain track mechanism to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a silent and smooth curtain track mechanism. Through a three-layer composite design of a buffer layer, a sound-absorbing layer, and a sound-absorbing sponge, the noise of the curtain track during operation is significantly reduced, creating a quiet indoor environment.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A silent and smooth curtain track mechanism includes a track mechanism body, with protective covers on both sides of the track mechanism body, and multiple pulley assemblies inside the track mechanism body, with fixing mechanisms at the lower ends of the multiple pulley assemblies;

[0007] The main body of the track mechanism includes a track body and two sound-absorbing sponges. A buffer layer is fixedly provided on the inner surface of the track body, and a sound-absorbing layer is fixedly provided on the inner surface of the buffer layer. Sound-absorbing grooves are provided on both sides of the inner wall of the sound-absorbing layer. Each of the multiple fixing mechanisms includes a connecting block, a first fixing bolt, a moving seat, multiple second fixing bolts and a fixing seat. Multiple positioning holes are provided on the front of each of the multiple moving seats, and mounting holes are provided on the front of each of the multiple fixing seats.

[0008] Furthermore, the buffer layer is made of rubber and is fixedly connected to the track body by a two-component neoprene rubber adhesive.

[0009] Furthermore, the sound-absorbing layer is made of POM (polyoxymethylene) material, and the sound-absorbing layer is fixedly connected to mechanical clips and a buffer layer by hot melt adhesive.

[0010] Furthermore, both of the sound-absorbing sponges are embedded inside the sound-absorbing groove.

[0011] Furthermore, the upper ends of the multiple connecting blocks are fixedly connected to the pulley assembly, and the upper ends of the multiple movable seats are slidably disposed inside the connecting blocks.

[0012] Furthermore, all of the aforementioned movable seats are fixedly connected to the first fixing bolt and the connecting block through positioning holes.

[0013] Furthermore, each of the aforementioned fixed seats is fixedly connected to a movable seat by a plurality of second fixing bolts.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model proposes a silent and smooth curtain track mechanism. The main body of the track mechanism adopts a three-layer composite design of buffer layer, sound-absorbing layer and sound-absorbing sponge. The rubber material of buffer layer absorbs the vibration generated by the rolling of pulleys and converts mechanical energy into internal energy consumption. POM polyoxymethylene in sound-absorbing layer has a low coefficient of friction, reducing friction noise between pulleys and track. The sound-absorbing sponge in the sound-absorbing groove absorbs sound waves through a porous structure, causing sound waves to reflect and lose energy in the pores. The three-layer structure works together to significantly reduce the noise of the curtain track during operation and create a quiet indoor environment.

[0016] 2. The present invention proposes a silent and smooth curtain track mechanism. The fixing mechanism can precisely control the curtain installation height by sliding the movable seat up and down in the connecting block and adjusting the positioning hole, so as to meet the installation needs of different windows. The detachable design of the fixing seat and the movable seat allows the fixing seat to be replaced separately when it is damaged, without the need to disassemble the entire track, reducing maintenance costs and difficulty. At the same time, the protective cover effectively prevents dust and debris from entering the track, reduces wear on the pulley assembly, extends the service life of the track mechanism, and improves the overall practicality.

[0024] 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.

[0025] Reference Figure 1-5 One embodiment of this utility model is a silent and smooth curtain track mechanism, which includes a track mechanism body 1, protective covers 2 on both sides of the track mechanism body 1, multiple pulley assemblies 3 inside the track mechanism body 1, and fixing mechanisms 4 at the lower ends of the multiple pulley assemblies 3.

[0026] Specifically, the main body 1 of the track mechanism achieves quietness and buffering through a multi-layer structure, the protective cover 2 can effectively prevent dust and debris from entering the interior of the track mechanism, keep the track mechanism clean, and extend its service life, the pulley assembly 3 provides a smooth curtain traction function, and the fixing mechanism 4 can adjust the installation height of the curtain fabric by using the hook assembly of the curtain fabric. All parts work together to achieve low noise and low friction operation of the curtain track.

[0027] Reference Figure 1-4 The main body 1 of the track mechanism includes a track body 101 and two sound-absorbing sponges 105. A buffer layer 102 is fixedly installed on the inner surface of the track body 101, and a sound-absorbing layer 103 is fixedly installed on the inner surface of the buffer layer 102. Sound-absorbing grooves 104 are opened on both sides of the inner wall of the sound-absorbing layer 103. The buffer layer 102 is made of rubber and is fixedly connected to the track body 101 by a two-component neoprene rubber adhesive. The sound-absorbing layer 103 is made of POM (polyoxymethylene) material and is fixedly connected to the buffer layer 102 by a hot melt adhesive and a mechanical buckle. The two sound-absorbing sponges 105 are embedded in the sound-absorbing grooves 104.

[0028] Specifically, in the main body 1 of the track mechanism, the track body 101 is the basic frame, the rubber material of the buffer layer 102 can absorb the vibration of the pulley assembly 3 during operation, the POM polyoxymethylene of the sound-absorbing layer 103 has a low coefficient of friction, reducing the rolling noise of the pulley, and the sound-absorbing sponge 105 in the sound-absorbing groove 104 absorbs sound waves through its porous structure. The three-layer structure significantly improves the sound-absorbing effect.

[0029] Reference Figure 1 , Figure 4 , Figure 5 Each of the multiple fixing mechanisms 4 includes a connecting block 401, a first fixing bolt 403, a movable seat 404, multiple second fixing bolts 405, and a fixed seat 406. Each of the multiple movable seats 404 has multiple positioning holes 402 on its front side, and each of the multiple fixed seats 406 has a mounting hole 407 on its front side. The upper ends of the multiple connecting blocks 401 are fixedly connected to the pulley assembly 3. The upper ends of the multiple movable seats 404 are slidably disposed inside the connecting blocks 401. Each of the multiple movable seats 404 is fixedly connected to the first fixing bolt 403 and the connecting block 401 through the positioning holes 402. Each of the multiple fixed seats 406 is fixedly connected to the movable seats 404 through the multiple second fixing bolts 405.

[0030] Specifically, in the fixing mechanism 4, the connecting block 401 is linked with the pulley assembly 3, and the movable seat 404 can slide up and down in the connecting block 401. The height can be adjusted through the positioning hole 402. The mounting hole 407 of the fixing seat 406 is used to install the hook assembly, so as to realize the quick disassembly and reassembly and position adjustment of the curtain. The detachable design of the fixing seat 406 makes it easy to replace when the fixing seat 406 is damaged, without having to replace the entire fixing mechanism 4, thus reducing the overall maintenance cost.

[0031] Working principle: When installing curtains, first, according to the required curtain height, loosen the first fixing bolt 403, slide the movable seat 404 up and down to the appropriate position, and then tighten the first fixing bolt 403 through the positioning hole 402 to fix it. Install the hook assembly into the mounting hole 407 of the fixing seat 406. After it is firmly fixed, hang the curtain rings on the hook assembly to complete the curtain installation. When the curtain is pulled, the pulley assembly 3 rolls in the main body 1 of the track mechanism, driving the fixing mechanism 4 to move synchronously. The buffer layer 102 in the track body 101 first absorbs the vibration generated by the rolling of the pulley. The elastic deformation of the rubber material converts the mechanical vibration into internal energy consumption. The POM polyoxymethylene surface of the sound-absorbing layer 103 is smooth and has a low coefficient of friction when in contact with the pulley, reducing the generation of high-frequency noise. The sound-absorbing sponge 105 inside the sound-absorbing groove 104 captures sound waves through its porous structure, causing the sound waves to reflect multiple times in the pores, thus reducing energy and further reducing noise. The protective covers 2 on both sides of the main body 1 of the track mechanism isolate the inside of the track from the external environment, effectively preventing dust, hair, debris and other foreign objects from entering, keeping the inside of the track mechanism clean, providing a good environment for the smooth operation of the pulley assembly 3, and extending the service life of the entire curtain track mechanism. In addition, when the fixing seat 406 is damaged due to long-term use, because it adopts a detachable design, the fixing seat 406 can be replaced separately by simply unscrewing the second fixing bolt 405, without disassembling the entire fixing mechanism 4. This is convenient and quick, reduces maintenance costs, and ensures that the curtain track mechanism can work continuously and stably.

[0032] 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.
