Description

Technical Field

[0001] This utility model belongs to the field of drawer slide technology, specifically relating to a slide with a buffer and silent structure. Background Technology

[0002] Drawer slides, also known as drawer slides or slide rails, are hardware connection components fixed to the cabinet body of furniture, allowing drawers or cabinet panels to move in and out. Drawer slides are suitable for connecting drawers in wooden and steel furniture such as cabinets, furniture, filing cabinets, and bathroom vanities; they have a wide range of applications.

[0003] In order to keep the drawer slides smooth, ball bearing retainers are usually installed between the slides. However, during the process of pulling the drawer out, the ball bearing retainers will rub against the slides, which can easily cause noise when the drawer is pulled out, affecting the user experience. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a slide rail with a buffer and silent structure to solve the problems mentioned in the background art.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A slide rail with a buffer and noise reduction structure includes a fixed rail, a middle rail slidably connected to the inner side of the fixed rail, an inner rail assembled and connected to the inner side of the middle rail, one side of the fixed rail connected to the middle rail, and the other side convex in shape, several through holes in the middle of the fixed rail, a sound-absorbing strip made of sound-absorbing material assembled and connected to the rear side of the fixed rail after the through holes, a ball retainer fixedly connected to the middle rail, the ball retainer having balls located between the middle rail and the fixed rail, a rubber strip in contact with the balls fixedly connected to the outer side of the inner rail, a first limiting member restricting the middle rail from disengaging from the fixed rail and a second limiting member restricting the inner rail from disengaging from the middle rail and the middle rail.

[0007] Furthermore, a connecting hole is provided on the outer side of the guide rail.

[0008] Furthermore, the connecting hole on the outer side of the guide rail is a straight groove type.

[0009] Furthermore, the inner end of the guide rail is equipped with a lubrication assembly.

[0010] Further specifying, the lubrication assembly includes a liquid bladder containing a lubricating substance, a receiving frame is assembled and connected to the end of the fixed rail, the liquid bladder is located inside the receiving frame, a pressure valve is assembled and connected to the liquid bladder, a cover plate is slidably connected to the open side of the receiving frame, a gap is left between the cover plate and the main body of the liquid bladder, a spring is assembled and connected to the inner side of the cover plate and the receiving frame, the pressure valve is assembled and connected to the cover plate, and the end of the inner rail is located inside the receiving frame.

[0011] Furthermore, the pressure valve is located on the upper side of the inner rail.

[0012] Further specified, the end of the inner rail is provided with a receiving cavity, the pressure valve is located above the receiving cavity, and a cylindrical roller is assembled and connected to the lower side of the receiving cavity at the end of the inner rail.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] This utility model has a simple structure. The fixed rail is designed to accommodate a sound insulation strip, which absorbs the noise generated when the middle rail slides relative to the fixed rail. At the same time, a rubber strip is provided on the inner side of the inner rail to reduce the noise generated when the ball bearings slide against the inner side of the inner rail, thus improving the user experience.

[0015] This invention features a lubrication assembly at the end of the inner rail. This lubricant lubricates both the fixed rail and the inner rail as the inner rail moves, ensuring smooth sliding without the need for manual lubrication of the balls. When the operator pushes the end of the inner rail until the cover plate squeezes the liquid bladder, the lubricant inside is forced into the receiving cavity. As the cylindrical roller rotates, the lubricant in the receiving cavity is carried out, further lubricating the slide rail and reducing its pulling resistance, thus reducing noise. Simultaneously, the spring acts as a buffer when the slide rail is pushed inward, reducing the possibility of impact and noise during the sliding process. Attached Figure Description

[0028] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] like Figure 1-7 As shown, a slide rail with a buffer and silent structure includes a fixed rail 1, a middle rail 2 slidably connected to the inner side of the fixed rail 1, an inner rail 3 assembled and connected to the inner side of the middle rail 2, one side of the fixed rail 1 connected to the middle rail 2, and the other side shaped like a convex character. Several through holes are opened in the middle of the fixed rail 1. Sound-absorbing strips 4 made of sound-absorbing material are assembled and connected to the back side of the fixed rail 1 behind the through holes. The sound-absorbing material is a sound-absorbing material such as sound-absorbing cotton. A ball retainer 5 is fixedly connected to the middle rail 2. The ball retainer 5 is provided with balls located between the middle rail 2 and the fixed rail 1. A rubber strip 31 that contacts the balls is fixedly connected to the outer side of the inner rail 3. The fixed rail 1 and the middle rail 2 are provided with a first limiting member 11 to restrict the middle rail 2 from separating from the fixed rail 1. The inner rail 3 and the middle rail 2 are provided with a second limiting member 12 to restrict the inner rail 3 from separating from the middle rail 2.

[0030] In this embodiment, the fixed rail 1 is fixedly connected to the outside of the drawer, the middle rail 2 is slidably connected to the fixed rail 1, and the inner rail 3 is fixedly connected to the drawer and slides with the drawer. When the drawer is pulled out, the inner rail 3 slides relative to the middle rail 2 and the fixed rail 1. A sound insulation strip 4 is fitted to one side of the fixed rail 1. The through hole in the fixed rail 1 is used to allow noise to pass through and reach the sound insulation strip 4. The sound insulation strip 14 is used to absorb the noise generated by the inner rail 3 sliding relative to the middle rail 2 and the fixed rail 1. At the same time, the rubber strip 31 contacts the ball bearing. Compared with the prior art, the hard contact between the ball bearing and the rail is changed to a soft contact, which also reduces the generation of noise.

[0031] Reference Figure 3The connecting hole on the outer side of the fixed rail 1 is a straight groove.

[0032] Reference Figure 1 Figure 3 and Figure 6-7 A lubrication assembly 6 is assembled and connected to the inner end of the fixed rail 1. The lubrication assembly 6 includes a liquid bladder containing a lubricating substance. A receiving frame 61 is assembled and connected to the end of the fixed rail 1. The liquid bladder is located inside the receiving frame 61. A pressure valve 62 is assembled and connected to the liquid bladder. A cover plate 63 is slidably connected to the open side of the receiving frame 61. A gap is left between the cover plate 63 and the main body of the liquid bladder. A spring is assembled and connected to the inner side of the cover plate 63 and the receiving frame 61. The pressure valve 62 is assembled and connected to the cover plate 63. The end of the inner rail 3 is located inside the receiving frame 61. The pressure valve 62 is located on the upper side of the inner rail 3. A receiving cavity is provided at the end of the inner rail 3. The pressure valve 62 is located above the receiving cavity. A cylindrical roller 65 is assembled and connected to the lower side of the receiving cavity at the end of the inner rail 3.

[0033] In this embodiment, the lubrication component 6 is used to move the lubricating object along the inner rail 3. The liquid bladder is used to hold the lubricating object, such as lubricating oil or grease, thereby lubricating the lower sides of the inner rail 3 and the middle rail 2. During the movement of the inner rail, the cylindrical roller 65 rotates, thereby carrying out the lubricating oil or grease in the receiving cavity, so that the lubricating object is brought to the contact side of the fixed rail 1, the middle rail 2, and the inner rail 3 during the movement. A gap is left between the cover plate 63 and the adjacent side of the liquid bladder 61 body. When the operator pushes the inner rail 3 connected to the drawer in, the end of the inner rail 3 contacts the cover plate 63 and does not contact the liquid bladder first. When the operator pushes the drawer inward a certain distance, causing the inner rail 3 to squeeze the cover plate 63, the cover plate 63 squeezes the spring, the spring is compressed, and the cover plate 63 squeezes the liquid bladder. The pressure on the liquid bladder is transmitted to the spring. Pressure valve 62 opens under pressure, allowing lubricant to flow into the receiving cavity. When it's not necessary to expel the lubricant, the user can simply push the drawer into the cabinet. This lubricates the slide rails as needed. Cylindrical roller 65 is in a sealed connection with the receiving cavity. When cylindrical roller 65 rotates, the lubricant in the receiving cavity is carried out, and cylindrical roller 65 lubricates the contact points. Simultaneously, the inner rail pushes inward and first contacts the cover plate 63. The cover plate 63 compresses the spring, and the spring, through deformation, buffers the slide rail. Additionally, an elastic element matching the lubrication components can be installed between the drawer cover and the cabinet. Under normal use, the elastic element limits the drawer cover; when further inward pushing is applied, the elastic element is compressed, expelling the lubricant.

[0034] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
