Description

A sliding member for hoisting a folding door screen partition

Technical Field

The invention belongs to the technical field of folding doors, and in particular relates to a sliding part used for hoisting folding door screen partitions.

Background technique

The existing household folding door is composed of a plurality of hinged folding door panels, and a slide rail is arranged above or below the folding door, and a sliding member sliding along the slide rail is arranged at the upper or lower end of each folding door panel, thereby forming a hoisting folding door installed in a hoisting manner.

However, in actual use, the sliding parts are often spaced in the middle of the top or bottom of the folding door panel, because when the folding door is unfolded or gathered, it is impossible to ideally unfold or gather all the folding door panels at the same time, that is, it is impossible to keep the middle of the top or bottom of each door panel on the straight line of the slide rail. In practice, the door panel closest to the user's hand is often gathered first to produce a hinged movement, while the door panel far away still remains unfolded. Therefore, the sliding parts are spaced to allow the top or bottom of the door panel to have a certain deformation range. Although this method of setting the sliding parts at intervals solves the problem of the deformation range of the sliding parts on the top or bottom of the door panel when the folding door is unfolded or gathered, the sliding parts, as far as the method of setting the sliding parts at intervals is concerned, because they act on the upper or lower end of each folding door panel, the unfolding or gathering of the folding door is more frustrated. At the same time, each sliding part will bear greater force when sliding, and is easily damaged, and the service life is greatly reduced.

Summary of the invention

The purpose of the present invention is to solve the problems existing in the prior art and to provide a sliding member for a suspended folding door, which can act on each folding door panel to improve the flexibility of the folding door when it is unfolded or gathered, while greatly increasing its service life.

Compared with the prior art, the present invention has the following outstanding and beneficial technical effects:

1. The sliding member for hoisting folding doors provided by the present invention, under the premise of being able to slide in the slide rail, does not need to keep the support rod in the sliding member in the middle position of the top or bottom of the door panel during the actual folding process of the door panel, and a certain offset between the side rods is achieved, thereby ensuring the structural strength of the support rod during actual use and preventing it from being damaged easily; and the sliding member can offset the support rod, so that each door panel can be provided with the sliding member, reducing the load-bearing capacity of the sliding members traditionally arranged at intervals, increasing the service life, and indirectly making the door panel smoother when unfolding or folding.

2. The present invention further forms a fixed horizontal plate at the bottom of the support rod, which can firmly fix the sliding part in the installation groove, and the fixed side plate can abut against the inner groove wall of the installation groove to increase friction and prevent the sliding part from sliding up and down in the installation groove.

3. The present invention adopts two side rods, and the two side rods form a "V"-shaped structure. The support rod is appropriately offset between the two side rods to provide a deformation range for the door panel to expand and collapse. The two side rods provide better stability during the deformation of the support rod.

4. The end of the side rod of the present invention adopts a mounting hole that matches the top of the side wall of the mounting groove, and uses a hook plate to hook together to ensure a good fixing effect.

5. The present invention further forms an end face of the slider parallel to the length direction of the slide rail, which makes the sliding smoother. The rotating part formed on the top of the support rod can rotate along the side of the rotating part when the door panel is folded and unfolded, thereby reducing friction without affecting the movement of the slider in the slide rail and avoiding rotation.

A sliding member for hoisting a folding door screen partition comprises a plurality of hingedly connected door panels 1, a sliding member 2 is arranged at the bottom or top of the door panel 1, a slide rail 3 for sliding the sliding member 2 is arranged above or below the door panel 1, a mounting groove 10 is opened in the middle of the top end or the middle of the bottom end of the door panel 1, the sliding member 2 comprises a slider 20 sliding along the slide rail 3, a support rod 21 is arranged at the bottom of the slider 20, a side rod 22 is arranged at the bottom of the support rod 21, and one end of the side rod 22 is connected to the top of the side wall of the mounting groove 10.

During the installation of the sliding member, the end of the side rod 22 is fixed to the top of the groove wall of the installation groove 10, at which time a part of the support rod 21 is inserted into the installation groove, and the sliding block slides into the slide rail.

In the above structure, the sliding part can be installed on the top or bottom of each door panel. By utilizing the effect of a certain moving range of the support rod, the support rod can be offset to a certain extent in the installation groove, which can meet the needs of folding multiple door panels. There is no need to worry about the problem that the sliding part cannot be kept in the same straight line with the slide rail during the actual sliding process. The sliding parts are set on the door panels one by one, which reduces the load-bearing capacity of each sliding part and extends the service life. The sliding is also smoother and the door panels can be better opened and closed.
