Buffering parts are arranged at the tail ends of the fixed rails, and buffering pieces are slidably connected to the inner sides of the buffering parts through buffering springs. According to the utility model, the fixed rail with the separated structure can be dynamically matched with the movement of the sliding rail, the rebound shaking effect generated in the drawing process is reduced, and the user experience is ensured.

Description

Technical Field

[0001] This utility model belongs to the field of slide rail technology and relates to a concealed slide rail with low rebound gap. Background Technology

[0002] Drawer slides, also known as drawer slides or slide rails, are hardware connecting parts 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. Existing concealed drawer slides, due to limitations in structural design or manufacturing precision, are prone to problems such as large rebound gaps, leading to drawers not closing properly, shaking, or noise, affecting the user experience. Therefore, designing a concealed drawer slide with low rebound gaps is essential. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a concealed slide rail with low rebound gap.

[0004] The objective of this utility model can be achieved through the following technical solution: A concealed slide rail with low rebound gap, comprising a fixed rail, characterized in that a set of symmetrical movable rail one and movable rail two are installed on the inner side of the fixed rail by several connecting springs, the movable rail one and movable rail two slide against the fixed rail, a certain gap is provided between the upper ends of the movable rail one and movable rail two and the fixed rail, a certain gap is also provided between the movable rail one and movable rail two, a guide groove is provided on the inner side of the movable rail one and movable rail two, and a slide rail is slidably installed through the guide groove, a number of fixing holes are provided on the outer side of the fixed rail, a buffer part is provided at the end of the fixed rail, and a buffer member is slidably connected to the inner side of the buffer part by a buffer spring.

[0005] The working principle of this utility model is as follows: First, the fixed rail is fixed in the designated position through the fixing hole. At this time, the movable rail one and movable rail two are in an initial closed state under the action of the connecting spring. Then, the sliding rail is installed at the bottom of the drawer to be used, and is manually inserted between movable rail one and movable rail two. At this time, movable rail one and movable rail two are in a default state of separation with a certain gap, completing the overall installation. When the drawer shakes or collides when pulled out or closed, the connecting spring enables movable rail one and movable rail two to cooperate with the sliding rail, and the gap between the rails provides cushioning. When the drawer is quickly closed, the sliding rail contacts the buffer, and the buffer spring provides effective cushioning.

[0006] A buffer pad is provided between the upper ends of movable rail one and movable rail two and the fixed rail, and between movable rail one and movable rail two.

[0007] The above structure provides a certain degree of buffering and protection.

[0008] A second buffer pad is installed at the end of the sliding rail.

[0009] The above structure provides a certain degree of buffering and protection.

[0010] The buffer section is provided with a positioning groove corresponding to the buffer component.

[0011] The above structure limits the movement trajectory of the buffer.

[0012] The guide grooves provided on the inner sides of the first and second movable rails are arc-shaped.

[0013] The above structure provides a better fit and can accommodate the movement of movable track one and movable track two.

[0014] Compared with existing technologies, this low-rebound-gap concealed slide rail has the following advantages: This utility model, by setting a fixed rail with a separate structure, can dynamically coordinate with the movement of the slide rail and reduce the rebound and shaking effect generated during the pulling process, thus ensuring user experience.

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figure 1-5As shown, this low-rebound-gap concealed slide rail includes a fixed rail 1. A set of symmetrical movable rails 3 and 4 are installed on the inner side of the fixed rail 1 through several connecting springs 2. The movable rails 3 and 4 slide against the fixed rail 1. A certain gap is provided between the upper ends of the movable rails 3 and 4 and the fixed rail 1. A certain gap is also provided between the movable rails 3 and 4. Guide grooves 5 are provided on the inner side of the movable rails 3 and 4, and a slide rail 6 is slidably installed through the guide grooves 5. Several fixing holes 7 are provided on the outer side of the fixed rail 1. A buffer part 8 is provided at the end of the fixed rail 1. A buffer element 10 is slidably connected to the inner side of the buffer part 8 through a buffer spring 9.

[0023] In this invention, the connecting spring 2 is a compression spring.

[0024] In this utility model, the gap between the upper ends of the movable rail 1 and the movable rail 2 and the fixed rail 1, and the gap between the movable rail 1 and the movable rail 2 are both set at 5mm.

[0025] In this utility model, the sliding rail 6 structure adopts the existing ball bearing sliding rail structure.

[0026] In this utility model, the buffer component 10 is made of rubber.

[0027] A buffer pad 11 is provided between the upper ends of movable rail 3 and movable rail 4 and the fixed rail 1, and between movable rail 3 and movable rail 4.

[0028] A buffer pad 12 is installed at the end of the sliding rail 6.

[0029] In this utility model, buffer pad 11 and buffer pad 22 are made of plastic material.

[0030] The buffer section 8 is provided with a positioning groove 13 corresponding to the buffer member 10.

[0031] The guide grooves 5 inside the movable rail 3 and movable rail 4 are arc-shaped.

[0032] The working principle of this utility model is as follows: First, the fixed rail 1 is fixed in the designated position through the fixing hole 7. At this time, the movable rail 3 and the movable rail 4 are in an initial state of mutual contact and closure under the action of the connecting spring 2. Then, the sliding rail 6 is installed at the bottom of the drawer to be used, and is manually inserted between the movable rail 3 and the movable rail 4. At this time, the movable rail 3 and the movable rail 4 are in a default state of separation with a certain gap, completing the overall installation. When the drawer shakes or collides when it is pulled out or closed, the connecting spring 2 enables the movable rail 3 and the movable rail 4 to cooperate with the sliding rail 6, and the gap between the rails provides cushioning. When the drawer is quickly closed, the sliding rail 6 contacts the buffer 10, and the buffer spring 9 provides effective cushioning.

[0033] In this invention, in the initial state, the dimension between movable rail 3 and movable rail 4 is smaller than the dimension of sliding rail 6. When sliding rail 6 is engaged between movable rail 3 and movable rail 4, connecting spring 2 is compressed and stores energy, thereby fitting sliding rail 6.

[0034] This utility model is equipped with a limiting structure similar to that of existing slide rails to prevent the slide rail 6 from separating from the fixed rail 1 after being pulled out to its maximum size.

[0035] In this invention, the various mechanisms are connected and driven using existing technologies.

[0036] All of the above components are general standard parts or components known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods.

[0037] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
