Description

Technical Field

[0001] This utility model relates to the field of glass door accessories, and in particular to a glass door frame bottom track. Background Technology

[0002] The bottom track of a glass door frame is a fixed track connecting the bottom edge of the door and the bottom track of the glass. During installation, it is fixed to the bottom edge of the door, allowing the glass bottom track to slide smoothly on the bottom track of the frame. Current glass door frame bottom track structures are fixed to the bottom edge by screws, thus requiring internal holes in the frame structure. This increases the difficulty of molding and material consumption. Furthermore, the screw installation method is unsuitable for doors with concrete walls at both ends. In existing technologies, the connection between the bottom track of the frame and the bottom track of the glass is often achieved by supporting and lubricating the bottom track of the glass. This method easily leads to dirt and water accumulation between the glass bottom track and the bottom track of the frame, causing rust or damage to components, noise, and obstruction of the glass door's sliding motion. Utility Model Content

[0003] In view of the defects of the existing technology, the technical problem to be solved by this utility model is to provide a door frame lower rail that can reduce the cost of the door frame lower rail, has a firm connection and is easy to install, and changes the connection method with the glass lower rail to make the glass door open and close more smoothly and with less noise.

[0004] To achieve the above objectives, this utility model provides the following solution:

[0005] A glass door frame lower track includes a track body, characterized in that: the track body is composed of a top support part and a bottom support part, a baffle is provided on one side of the top support part, a reinforcing bending part is provided on one side of the bottom support part, and a connecting part one and a connecting part two connecting the lower door edge and the glass lower track are respectively provided at the bottom of the bottom support part and the top support part.

[0006] Furthermore, in this utility model, the top support and the bottom support are integrally formed, and a central space is formed between the two.

[0007] Furthermore, in this utility model, one end of the top support portion is connected to a baffle strip, and the other end is bent downward in an arc shape, wherein the baffle strip and the arc shape bend are integrally formed.

[0008] Furthermore, the baffle in this utility model is n-shaped and protrudes upward from the top support portion.

[0009] Furthermore, the reinforcing bending portion in this utility model is located on the side of the bottom support portion near the connecting portion two, and the reinforcing bending portion protrudes outward.

[0010] Furthermore, the connecting part of this utility model includes two side members disposed on the bottom support part and a middle member disposed between the two side members, and a T-shaped cavity is formed between the side members and the middle member.

[0011] Furthermore, the connecting part 2 in this utility model includes several upright plates disposed at the bottom of one side of the top support part, and side members 2 are disposed on both sides of the upright plates and on the side wall of the bottom support part, forming a T-shaped cavity 2 between every two side members 2 disposed vertically.

[0012] In summary, the advantages of this utility model over the prior art are:

[0013] This utility model features a simple structure. It removes the screw-connecting parts inside the lower door frame track and uses a connecting part to connect to the lower door edge. After positioning, it is fixed with adhesive, achieving an effect almost identical to fixing with screw holes. This significantly reduces structural costs and facilitates easy installation. Furthermore, the second connecting part is adaptable to double-door or triple-door structures. The lower glass track uses a non-bottom-supporting limiting mechanism, leaving it suspended. The glass slides via the upper track, preventing dirt accumulation at the bottom and reducing water damage to the lower glass track. This results in smoother sliding and reduced noise.

[0015] Figure 2 This is an assembly drawing of the present invention with glass, glass bottom track, door bottom edge, and cotton strip. Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0017] like Figures 1 to 2The present invention preferably provides a lower track for a glass door frame, comprising a track body 1. The track body 1 is characterized by comprising a top support portion 11 and a bottom support portion 12. A stop strip 2 is provided on one side of the top support portion 11, and a reinforcing bending portion 3 is provided on one side of the bottom support portion 12. Connecting portions 4 and 5, respectively, are provided at the bottom of the bottom support portion 12 and the top support portion 11, connecting the lower door edge and the lower glass track. The track body is installed on one side of the lower door edge. The portion on the side of the stop strip serves as the receiving position for the lower glass track. Users can choose between double or triple doors according to their needs. Specifically, the lower glass track near the stop strip does not need to be connected to connecting portion 2, while the remaining lower glass tracks need to be connected to connecting portion 2. Connecting portion 1 is used to install the track body onto the lower door edge. Connecting portion 1 is inserted to achieve positioning and front-to-back limiting. It is fixedly connected to the lower door edge by applying adhesive. The lower door edge can be joined to connecting portion 1 via an integrated protrusion or directly by applying adhesive. Strengthening the bending section enhances the function of the track body, making the top part of the connecting section that connects to the track body less prone to bending. The top support part is used to mate with the lower glass track, and the bottom support part is used to mate with the lower edge of the door.

[0018] In this invention, the top support portion 11 and the bottom support portion 12 are integrally formed, with a central space 13 formed between them. The central space is sealed, which can reduce water accumulation and dirt buildup. The integral molding of the top and bottom support portions reduces processing difficulty and lowers costs.

[0019] In this invention, the top support portion 11 is connected to a stop strip 2 at one end and has a downward arc-shaped bend 6 at the other end. The stop strip 2 and the arc-shaped bend 6 are integrally formed. The stop strip is located at one end of the top support portion and serves to limit movement and prevent the lower glass track from detaching. The arc-shaped bend makes the installation transition of the lower glass track smoother and avoids sharp corners.

[0020] The baffle 2 described in this utility model is n-shaped and protrudes upward from the top support portion 11.

[0021] In this invention, the reinforcing bending portion 3 is located on the side of the bottom support portion 12 near the connecting portion 5, and the reinforcing bending portion 3 protrudes outward. The outward protrusion makes the arc-shaped bend less prone to deformation and damage.

[0022] The connecting part 4 described in this utility model includes two side members 41 disposed on the bottom support part 12 and a central member 42 disposed between the two side members 41, forming a T-shaped cavity 43 between the side members 41 and the central member 42. The T-shaped cavity can accommodate the insertion of a protruding strip, which is generally integrated into the lower edge of the door. When there is a protruding strip, glue can be applied to the two side members of the T-shaped cavity; when there is no protruding strip, glue can be directly applied to seal the lower edge of the door.

[0023] The connecting part 2 5 of this utility model includes several upright plates 51 disposed at the bottom of one side of the top support part 11. Side members 2 52 are disposed on both sides of the upright plates 51 and on the side wall of the bottom support part 12. A T-shaped cavity 2 53 is formed between every two vertically disposed side members 2 52. The upright plates form two spaces on the left and right sides, which can be connected to two different glass bottom rails respectively. Cotton strips can be installed in each T-shaped cavity 2 to reduce the contact surface.

[0024] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
