Embodiment Construction

[0029] figure 1 It is a structural schematic diagram of an embodiment of the spring assist device of the present invention; figure 2 for figure 1 Sectional view of the spring assist device in . like figure 1 and figure 2 As shown, the spring booster 17 of the present invention is used for automatic translation doors, and includes a tubular housing 5 and a spring 8 disposed in the housing 5 along the length direction of the housing 5. One end of the housing 5 is provided with a top wire 7. The other end is provided with a push rod, and one end of the spring 8 is against the top wire 7. In this embodiment, the jacking wire 7 is connected to the housing 5 through the external thread on its outer wall and the internal thread on the inner wall of the housing 5, and the end of the jacking wire 7 abutting against the spring 8 has a positioning for one end of the spring 8 to pass through. The column can make the spring 8 more stable and will not shake in the housing 5 when it i...

Abstract

The invention relates to a spring assistance device and an automatic sliding door. The spring assistance device is used in the automatic sliding door and comprises a pipe type shell and a spring; the spring is located in the shell and arranged along the length direction of the shell; one end of the shell is provided with a jackscrew; the other end of the shell is provided with a push rod; one end of the spring abuts against the jackscrew; the other end of the spring is compressed by the push rod towards the direction of the jackscrew when the automatic sliding door is closed; the shell is also provided with installation brackets; and the installation brackets are fixedly connected with a track of the automatic sliding door. According to the spring assistance device and the automatic sliding door provided by the invention, the defects of high cost and complicated structure of the existing automatic sliding door of which a door body is heavier or the door body is required to sink are overcome; and therefore, the spring assistance device which can enable the automatic sliding door to save energy and be simple in structure is provided.

Description

technical field [0001] The invention relates to a translation door, in particular to a spring assist device and an automatic translation door provided with the spring assist device. Background technique [0002] The automatic translation door moves along the track fixed to the wall under the drive of the driving motor, so as to open or close. An automatic sliding door generally includes a door frame, a door body, a track, a driving device and a control device for controlling the operation of the driving device. When the door body is heavier, its opening resistance will also increase accordingly. In addition, when the automatic sliding door is used for sealing, in order to achieve a good sealing effect, it is generally designed to make the door sink when it is closed and gradually rise when the door is opened. Therefore, it is necessary to set the track to be closed. A structure with a low end, a high open end and a slope. At this time, due to the effect of gravity, the re...
