Detailed Description

The invention will be further described in the following with reference to the accompanying drawings in which:

referring to FIGS. 1-7: the utility model provides a door curtain fossil fragments, includes fossil fragments body 1, and 1 middle part fretwork of fossil fragments body forms door curtain arrangement groove 2, and the front side in door curtain arrangement groove 2 is that the front splint 3, rear side are the back splint 4, be provided with first constant head tank 5 on the front splint 3, first constant head tank 5 is the strip setting, and the fastener can be settled at the optional position of first constant head tank 5, and the fastener is got through and is passed first constant head tank 5 after-fixing on back splint 4.

First constant head tank 5 is the strip setting, consequently through this structure, the user only need tentatively aim at first constant head tank 5 with the fastener, and the fastener can pass the optional position of first constant head tank 5 and fix on splint 4 behind for the mounted position of fastener is more free, has reduced the installation degree of difficulty of door curtain fossil fragments, has effectively reduced the danger of installing this eminence operation of door curtain fossil fragments.

The rear side thickening protrusion of back splint 4 forms first connecting portion 6, first connecting portion 6 corresponds with the position of first constant head tank 5 back-to-back, first connecting portion 6 can supply the fastener to penetrate and fix.

First constant head tank 5 and first connecting portion 6 all utilize the fastener to destroy the mode of shape and carry out fixed connection by force for the fastener all hugs closely the adaptation with fossil fragments body 1 in first constant head tank 5 and first connecting portion 6 department, has reduced the space that produces between fastener and the fossil fragments body 1, has reduced door curtain fossil fragments installation and has accomplished the back and take place the vibration and rock, so connect more stably, door curtain fossil fragments's life is longer.

Two sides of the front clamping plate 3 are provided with first positioning grooves 5; the door curtain is more stable after being installed, and the door curtain is safe to use and long in service life.

The upper end of the keel body 1 is provided with a fixing part 7, the fixing part 7 is higher than the door curtain placing groove 2, a second positioning groove 8 is formed in the fixing part 7, the second positioning groove 8 is arranged in a strip shape, a fastener can be placed at any position of the second positioning groove 8, and the fastener penetrates through the fixing part 7 at the second positioning groove 8 and is connected and fixed outwards; compared with the traditional mode of punching and installing the door curtain keel, the mode of fixing the door curtain keel by the second positioning groove 8 enables the connecting position of the fastener to be more free, and the installation difficulty of the door curtain keel is reduced.

The rear part of the fixing part 7 is thickened and protruded to form a second connecting part 9, the positions of the second connecting part 9 and the second positioning groove 8 correspond to each other in the front-back direction, and a fastener passes through the second connecting part 9; the contact area between the fastener and the fixing part 7 is larger, and the connection is tighter.

When the utility model discloses a door curtain fossil fragments install on wall/door frame, utilize the plane contact of first connecting portion 6 and second connecting portion 9 with wall/door frame, reduced the area of contact of door curtain fossil fragments with wall/door frame for the plane that the monoblock and wall/door frame were hugged closely need not processed out to the door curtain fossil fragments, has reduced the processing degree of difficulty of door curtain fossil fragments, has made things convenient for production.

The front side of the upper end of the keel body 1 is recessed inwards to form a fixing part 7; the thickness of the fixing part 7 is smaller, the difficulty of the fastener penetrating through the fixing part 7 is reduced, and the installation is more convenient; in addition, this arrangement reduces contamination of the fastener placed on the fixing portion 7 with rainwater and dust, resulting in a longer service life.
