Chain structure of screen device

The present invention relates to a chain structure, and more particularly to a chain structure of a screen device capable of reducing chain sliding noise.

According to the current construction opening, in addition to the installation of doors and windows, a screen device will be installed, and the folding net or roll gauze in the screen device will be deployed to prevent outdoor mosquitoes and dust from entering. The benefits such as indoors have led to a trend toward more and more people using screen devices.

According to an international patent application number: PCT/JP2007/062506, a conventional screen device (9) is disclosed, as shown in the first figure, and the screen device (9) mainly includes a gauze (91). Two columns (92) and two chains (93); wherein the gauze (91) is disposed between the two materials (92), and the center of the two materials (92) is hollow, and the two chains (93) One end (931) is connected to one of the vertical materials (92), and the other end (932) of the two chains (93) can enter and exit the material through the upper and lower ends (921) of the vertical material (92) ( 92); that is, when one of the stocks (92) is slidably actuated, in addition to being able to unfold the gauze (91), the two chains (93) can also be pulled out of the stock (92), so that The two chains (93) can be disposed above and below the gauze (91) to guide the unfolding of the gauze (91); and when the vertical (92) rows are reversely slipped, the gauze can be stored (91). In addition, the two chains (93) can also be pushed into the stock (92).

However, the current screen device (9) can achieve the expected benefits of housing and unfolding the gauze (91), and the two chains (93) are pivotally connected by a plurality of chain carriers (933), so that the two chains (93) When entering and leaving the stock (92), it can be bent by the pivoting of the chain carriers (933), so that the two chains (93) are not moved into and out of the stock (92) and the lower end (921). The stuck line is not smooth; however, the chain (93) used in the current screen device (9) has a loose fit between the chain carriers (933), so that the two chains (93) are in the process of slipping. Often noise is generated by the pivotal friction between the chain carriers (933), and the chain (93) located in the stock (92) is more swayed by the pivoting of the chain carriers (933) with the stock ( 92) The collision of the inner wall, thus the amount of noise generated by the larger chain (93) when sliding.

The main object of the present invention is to provide a chain structure of a screen device capable of reducing chain sliding noise.

In order to achieve the above object, the present invention provides a chain structure of a screen device, comprising: a plurality of chain carriers, wherein at least the two adjacent chain carriers are provided with a consolidation device, and the consolidation device can The two adjacent chain carriers are consolidated into one body; so that the plurality of chain carriers in the chain structure of the screen device can be consolidated with each other by the above-mentioned structural arrangement, so that the mutually consolidated chain carriers are slid to the screen device When the material is in the material, the opportunity of the chain carrier to hit the inner wall of the vertical material due to the pivoting operation can be reduced, so that the noise generated by the chain structure in the slip can be effectively reduced.
