Fig. 4, three strikes off the action diagram of the rain brush of sheet;

Fig. 5, another kind of rain brush embodiment block diagram.

Now in conjunction with the accompanying drawings three structures of striking off the rain brush of sheet are described in detail.

By Fig. 1, swing arm 1 is provided with the necessary engagement groove 11 and the hook 12 of bottom side, makes it be bonded to oscillating structural member by engagement groove 11, and can combine with pedestal 2 with hook 12.Pedestal 2 is used for linking and strikes off sheet 4 and swing arm 1, one concordant top is arranged itself, have the wing 21 that protrudes to a side, fin 21 can be by the hook 12 embeddings folder of swing swing arm 1 thus, and a storage tank 22 is arranged at pedestal 2 bottoms, this groove can or strike off sheet 4 with embedding holder 3 and combine, this groove can be positive toroidal, make both in conjunction with after can become the preferred rotary effect, storage tank 22 outer walls are provided with and protrude bar 23, when embedding holder 3 or when striking off sheet 4 rotation, can with protrude bar 23 and contact and stop.

Embedding holder 3 is to be provided with round tube or post can embed in the storage tank 22 of pedestal 2 by the top, embedding holder 3 can be rotated for 2 one-tenth smoothly to pedestal, embedding holder 3 bottoms are provided with three grooves 31, medial launder 31 ends slightly wherein, about the groove 31 of two sides slightly high, strike off sheet 4 and just be embedded in the groove 31, shoulder 32 is formed on embedding holder 3 tops, when 3 pairs of pedestals of embedding holder 2 rotated, shoulder 32 can contact with the protrusion bar 23 of pedestal 2, and 3 rotations of embedding holder are stopped.

Striking off sheet 4 draws with pedestal 2 storage tanks 22 or embedding holder 3 grooves identical section form is arranged, making this strike off sheet 4 can be in conjunction with in the right inlay card seat 3, or directly be combined in the pedestal 2, can be according to storage tank 22 rotations, strike off sheet 4 pin 41 that stretches out is downwards arranged itself, pin 41 terminals form pointed, and pin 41 itself also has the outer rib 42 of horizontal protrusion.

By Fig. 2, strike off sheet 4 and be combined in the embedding holder 3, embedding holder 3 is combined in the storage tank 22 of pedestal 2, again by in the hook 12 of this groove 22 in conjunction with right swing arm 1.

By Fig. 3, swing to the left when moving when the moving bar 1 of swing, 3 pairs of pedestal work of whole embedding holder anticlockwise direction rotates, the sheet 4a that strikes off in left side is scraped earlier, and the middle sheet 4b that strikes off does the action of striking off of following, and makes glass sheet strike off operation through two pass, and it is more clean that it strikes off effect.

By Fig. 4, when swing arm is swung to the right, embedding holder 3 is just made right-hand revolution to pedestal 2, and the right side is struck off sheet 4c and scraped earlier, and strike off sheet 4b by the centre again and do the work of striking off of following, therefore, the operation that glass sheet equally also has two pass to strike off.

By Fig. 5, this rain brush directly strikes off sheet 4 by swing arm 1 embedding holder 3 and forms, the top pipe or the post of embedding holder 3 are made bigger rounded nose, make the hook 12 direct embeddings of swing arm 1 bottom press from both sides this embedding holder 3, make scraping blade 4 directly to swing arm 1 rotation thus, and sheet 4a can be struck off in two in the outside of striking off sheet 4, and 4c makes bristle 5 shapes into, and it can brush the sandstone on the glass sheet fall during use.

Compared with prior art, three rain brush that strike off sheet have following advantages:

1, the outside two is struck off sheet and is struck off striking off that sheet does to follow in the middle of striking off earlier, and effect is better, the centre To strike off sheet not fragile yet.

2, comparatively convenient to the driver, guarantee traffic safety.

3, respectively striking off sheet can change separately.
