Description

A lower rail assembly suitable for press-fit sliding doors

technical field

The utility model belongs to the field of doors and windows, and relates to a sliding rail assembly suitable for press-fitting sliding doors.

Background technique

As a kind of opening method, sliding door has been well known by people. Compared with swing door products, sliding door has poor watertightness and airtightness due to its own structure. The main reason is that the existing sliding door installs tops in the cavity of the sliding fan, and the tops are sealed by contacting the sliding track through the tops. Under the condition of force, the tops are easily deformed, and the sealing effect cannot be achieved after deformation; frequent maintenance and replacement of tops is required. These in turn lead to a shortened service life of the sliding door. And the sliding doors on the existing market are based on aluminum alloy and plastic steel doors, which are more difficult to change its watertightness and airtightness.

Sliding hole B; the sliding part is placed in the clamping groove of the sliding plate, and the upper end cover has a fixed plate; the fixed shaft pin passes through the sliding hole B and the straight strip hole, and is fixed in the shaft pin hole A; the sliding shaft pin passes through the sliding hole A and the arc-shaped long hole and then fixed in the shaft pin hole B; there are two vertical pulley fixing seats on the upper surface of the fixed plate, and the two vertical pulleys are hinged between the two pulley splints through the pivot pin, and the two pulley splints are fixed on the On the fixed shaft stretching out from the front and rear of the fixed seat on the end surface of the fixed plate.

The above-mentioned utility model also includes a transverse pulley, the upper end of the fixed seat also has a fixed end of the transverse pulley, and the transverse pulley is hinged on the upper end of the fixed seat; there is also a positioning groove for the transverse pulley on the lower rail; the transverse pulley is located on the transverse pulley. in the positioning slot. The horizontal pulley plays the role of positioning protection to prevent the vertical pulley from derailing.

When in use, the lower pulley assembly is fixed in the groove rail B at the lower end of the push-pull fan frame through the fixing hole A on the sliding plate; the two vertical pulleys are clamped on the lower rail on the threshold; The pin is fixed on the transmission bar. As long as the handle is rotated, driven by the handle, the lower pulley assembly will move from outdoor to indoor, so that the push-pull fan will press the sealant between it and the fixed fan, the upper frame, the lower frame and the right or left frame in contact with it. strip, the lock hook of the fan hook lock locks the locking block tightly; the wool strip can be removed by adopting the press-fit sliding door of the utility model, and the sealant strip is used for sealing, and the sealing effect is good, greatly increasing its watertightness and airtightness, and its High locking reliability and long service life; and the greater the wind pressure, the better the sealing effect. The utility model is more suitable for doors and windows such as aluminum clad wood sliding doors, aluminum alloy sliding doors, wood clad aluminum sliding doors and the like.
