AI Technical Summary
Existing car seat belt plug-ins are prone to fall off the guide rails, especially when they are subjected to upward tension for a long time, which can easily slide and fail or fail, affecting the use effect.
The side connection structure between the U-shaped rail groove and the guide rail is adopted. The rail frame is suspended above the frame connection plate by raising the connection plate, and is fixed with bolts to ensure the stable coordination between the U-shaped rail groove and the guide rail.
The connection strength of the seat belt plug-in on the guide rail is improved to prevent upward disengagement, avoid obstruction of the sliding function, and ensure the continuous use of the seat belt plug-in.

Abstract
Description
Technical Field
[0001] The utility model belongs to the field of automobile accessories and relates to an assembly structure of an automobile safety belt, in particular to an anti-falling guide rail assembly for the automobile safety belt. Background Art
[0002] The car seat belt plug-in is installed on the guide rail frame by means of a slide rail, so that the seat belt plug-in can be adjusted by sliding. Figure 1 As shown, the two guide rails of the existing guide rail frame are upward, and the guide rail grooves on the seat belt plug are longitudinally matched on the guide rails. This structural connection method causes the seat belt plug to easily fall off the two guide rails. In particular, if the seat belt plug is subjected to upward tension for a long time, the seat belt plug is likely to fall off the guide rails upward, and the sliding function is likely to be blocked and fail, which seriously affects the continued use of the seat belt plug. Summary of the Invention
[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, an anti-falling guide rail assembly for automobile seat belts is provided, which adopts a U-shaped guide rail groove and a side connection structure of the guide rail to improve the connection strength of the seat belt plug-in on the guide rail, and in particular can prevent the seat belt plug-in from detaching upward from the guide rail, thereby avoiding the obstruction and failure of the sliding function of the seat belt plug-in, and ensuring the continuous use of the seat belt plug-in.
[0004] Technical solution: In order to achieve the above-mentioned purpose, the utility model provides an anti-falling guide rail assembly for automobile seat belts, including a guide rail frame, two guide rails arranged on the guide rail frame and a seat belt plug-in matched with the two guide rails. Both ends of the guide rail frame are provided with height-adjusting connecting plates. The guide rail frame is suspended and fixed above the frame connecting plate through the two height-adjusting connecting plates. The two guide rails are respectively arranged on the two side edges of the guide rail frame. The seat belt plug-in is provided with a U-shaped guide rail groove matching the guide rail. The seat belt plug-in is matched on the two guide rails through the two U-shaped guide rail grooves.
[0005] Furthermore, the height-adjusting connecting plate includes a height-adjusting portion and a connecting portion, the height-adjusting portion is respectively connected to the guide rail frame and the connecting portion, and the height-adjusting portion is inclined upward toward the guide rail frame, so that the guide rail frame can be suspended above the frame connecting plate, providing sufficient space for the U-shaped guide rail groove and the guide rail to be connected sideways.
[0006] Furthermore, a bolt hole is provided on the connecting portion, and the connecting portion is bolted to the frame connecting plate through the bolt hole.
[0007] Furthermore, one of the two connecting parts is provided with a positioning block, which can preliminarily position the connecting part at one end, thereby facilitating the subsequent installation operation of the guide rail frame on the frame connecting plate.
[0008] Furthermore, the guide rail frame and the height adjustment connecting plate are integrally formed.
[0009] Beneficial effect: Compared with the prior art, the present invention can suspend the guide rail frame above the frame connecting plate, and adopts a U-shaped guide rail groove and the side connection structure of the guide rail, which improves the connection strength of the seat belt plug-in on the guide rail, and can especially prevent the seat belt plug-in from upwardly detaching from the guide rail, avoiding the obstruction and failure of the sliding function of the seat belt plug-in, and ensuring the continuous use of the seat belt plug-in.

[0011] Figure 2 This is a structural connection diagram of the height-adjusting connecting plate on the guide rail frame in the utility model;
[0012] Figure 3 This is a schematic diagram of the assembly of the safety belt insert on the guide rail frame in the present utility model. DETAILED DESCRIPTION
[0013] The present invention is further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. After reading the present invention, modifications of various equivalent forms of the present invention made by those skilled in the art all fall within the scope defined by the claims attached to this application.
[0014] like Figure 1 and Figure 2 As shown, the utility model provides an anti-falling guide rail assembly for a car seat belt, comprising a guide rail frame 1, two guide rails 2 arranged on the guide rail frame 1 and a seat belt plug 7 fitted on the two guide rails 2. Both ends of the guide rail frame 1 are provided with a height adjustment connecting plate, which includes a height adjustment portion 3 and a connecting portion 4. The height adjustment portion 3 is respectively connected to the guide rail frame 1 and the connecting portion 4. The height adjustment portion 3 is tilted upward toward the guide rail frame 1 so that the guide rail frame 1 can be suspended above the frame connecting plate (not shown in the figure). A bolt hole 5 is opened on the connecting portion 4, and the connecting portion 4 is passed through It is connected to the frame connecting plate through the bolt hole 5, one of the connecting parts 4 is provided with a positioning block 6, and the frame connecting plate is provided with a positioning hole matching the positioning block 6 (not shown in the figure). The guide rail frame 1 and the height adjustment connecting plate are formed as one piece, and the two guide rails 2 are respectively provided on the two side edges of the guide rail frame 1. The seat belt plug-in 7 is provided with a U-shaped guide rail groove 8 matching the guide rail 2. The seat belt plug-in 7 is fitted on the two guide rails 2 through the two U-shaped guide rail grooves 8, so that the seat belt plug-in 7 can slide along the two guide rails 2, thereby having a sliding position adjustment function.
[0015] In this embodiment, the above-mentioned guide rail assembly is installed on the frame connecting plate of the automobile frame. First, the positioning block 6 is inserted into the specified positioning hole to achieve the preliminary positioning of the guide rail frame 1 on the frame connecting plate. Then, the two bolt holes 5 are adjusted to the specified positions by rotating the adjustment angle, and the guide rail frame 1 is fixedly installed on the frame connecting plate by bolt connection. At this time, due to the relationship between the two height adjustment parts 3, the guide rail frame 1 is suspended above the frame connecting plate. There is a certain space between the guide rail frame 1 and the frame connecting plate, so that the U-shaped guide rail groove 8 of the seat belt plug 7 pre-installed on the two guide rails 2 of the guide rail frame 1 has a placement space.
[0016] like Figure 3 As shown, after the seat belt plug-in 7 is installed, the U-shaped guide rail groove 8 wraps around the guide rail 2 from the side. This connection structure makes it almost impossible for the U-shaped guide rail groove 8 to separate from the guide rail 2. The seat belt plug-in 7 is not easy to separate from the guide rail frame 1 regardless of whether it is subjected to upward tension or lateral tension, thereby improving the connection strength of the seat belt plug-in 7 on the guide rail 2, and can prevent the seat belt plug-in from separating from the guide rail 2, avoiding the occurrence of obstruction and failure of the sliding function of the seat belt plug-in 7, and ensuring the continuous use of the seat belt plug-in 7.
