Description

Wind screen wiper

The utility model relates to a kind of automobile-used accessory, particularly a kind of automobile-used rain brush that is used for the use of vehicle glazing brushing.

Existing automobile-used rain brush constitutes by the swing arm of a blade insert and embedding folder scraping blade, and in use, the right left side of swing arm swings and drives scraping blade and is synchronized with the movement, and so that misty rain or frost and snow are struck off, thereby guarantees for the driver drives to provide to observe.

The point of the deficiency of this class rain brush is: about in the pendulum Zhe process, blade insert is very easy in fixedly embedding folder place root breakdown, thereby causes the inefficacy of rain brush, thereby influences driver's traffic safety and moving velocity.

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect of existing in prior technology, and a kind of preferable effect of striking off that both had is provided, and has the automobile-used rain brush in long service life again.

The purpose of this utility model is to realize by following technical scheme: it is by swing arm, pedestal, embedding holder and the scraping blade formation that is connected, pedestal 2 is inserted and is embedded in the swing arm, the embedding holder inserts again in pedestal, scraping blade is inserted in the embedding holder, pedestal top is the plane and is strip, the most cylindric ccontaining cover of one under shed is arranged at the pedestal bottom, the cylinder position on embedding holder top is inserted in the ccontaining cover of pedestal, the top boss bar part and pipe position, the embedding holder top plug-in mounting of scraping blade, two big font scraping blades are arranged at the scraping blade bottom, the most cylindric ccontaining cover both sides of pedestal are provided with the clamp of evagination, when swing arm swung, the embedding holder dragged left-right rotation certain radian in the following ccontaining cover at pedestal 2 at scraping blade.

Therefore remarkable result of the present utility model is:

1, because scraping blade and embedding holder relative fixed, the embedding holder then with the sleeve piecemeal activity plug-in mounting of pedestal, therefore, when the scraping blade lower end produces friction force with being contacted by shaving, the embedding holder is then circumferentially done swinging back and forth of certain radian along the sleeve endoporus, solved when scraping blade is worked by simple frictional movement and turned over the Zhe action, greatly improved its service life.

2, because the ccontaining cover bottom of pedestal is provided with the spacing clamp of evagination, therefore, when embedding holder slot position contacted with spacing clamp, scraping blade promptly stopped to continue to this orientation rotation.

3, the setting of big font shape scraping blade guarantees that not only it has secondary and strikes off effect, its root intensity is increased, and the front portion has malleable preferably.

Concrete structure of the present utility model is realized by the following examples and accompanying drawing thereof:

Fig. 1 is STRUCTURE DECOMPOSITION figure of the present utility model.

Fig. 2 is a lateral plan of the present utility model.

Fig. 3 is the utility model working state figure.

Fig. 4 is that of the present utility model another executed the STRUCTURE DECOMPOSITION figure of example.

Below in conjunction with accompanying drawing 1-4 to being that concrete structure of the present utility model is described in detail:

The utility model has swing arm 1 and scraping blade 4, swing arm 1 is provided with the grab 12 and the engagement groove 11 of symmetry, it is characterized in that: the wing plate 21 on pedestal 2 tops is inserted build-in mutually with the grab 12 of swing arm 1 bottom and is decided, activity is fitted with embedding holder 3 in the ccontaining cover of pedestal 2 bottoms, be inserted with scraping blade 4 in the embedding holder 3, scraping blade 4 tops are rounded, pin 41 is scraped for the compasses shape of fork in the bottom, and the symmetry evagination has and embedding holder 3 bottom draw-in groove convex shoulders 32 contacted spacing clamps 23 in pedestal 2 bottoms.Referring to Fig. 1 to Fig. 3.

Architectural feature of the present utility model also is:

Pedestal 2 tops of strip shape are tabulars and are arranged with the wing plate 21 of inserting embedding with swing arm 1 bottom grab 12 mutually, what be connected as a single entity with pedestal 2 flat parts of strip shape is the ccontaining cover 22 that protruding front and back connect, ccontaining cover 22 bottoms are the under shed shape, at the protruding spacing clamp 23 that two symmetries are arranged of ccontaining cover 22 circumferential lower horizontal sides, the lower open mouth tube-shaped tube 33 that the front and back on embedding holder 3 tops connect and the ccontaining cover 22 movable plug-in mountings of pedestal 2, the logical rectangle draw-in groove 31 that slits up and down that connects before and after embedding holder 3 tube-shaped tubes 33 bottoms have, protruding draw-in groove convex shoulder 32 upper surfaces of rectangle draw-in groove 31 horizontal symmetrical sides contact mutually with the spacing clamp 23 of pedestal 2 or break away from, and the cross sectional shape of elastic doctor blade 4 is the compasses shape and slotting being embedded in the embedding holder 3 of fork.Referring to Fig. 1, Fig. 3 and Fig. 4.

Elastic doctor blade 4 tops are that thick circle such as front and back transplants a cutting 43, and what transplant a cutting that 43 bottoms are connected as a single entity with circle is that pin 41 scraped in a big font.Referring to Fig. 1 to Fig. 3.

Pin 41 tops scraped in big font is one to insert the snap portions 44 of embedding mutually with embedding holder 3 bottom rectangle draw-in grooves 31, and pin 41 is scraped for the big font of fork in snap portions 44 bottoms, and big font is scraped foot 41 and is provided with reinforcement rib 42.Referring to Fig. 1 and Fig. 2.

The utility model principle of work is:

When swing arm 1 swings, scrape 41 on pin with the bottom of being scraped surperficial contacted scraping blade 4 and produce friction and scrape and make a concerted effort and make to transplant a cutting 43 with the top of scraping blade 4 to insert the embedding holder 3 of embeddings also stressed and can rotate certain radian ccontaining cover 22 in, scrape with the backswing that comes of formation scraping blade 4.Referring to Fig. 2 and Fig. 3.

When draw-in groove convex shoulder 32 tops contacted with spacing clamp 23 in swing process, then scraping blade can not continue to same direction swing again.

Structure shown in Figure 4 and Fig. 1 are basic identical, and difference can be cancelled embedding holder 3 exactly, and scraping blade 4 upper circular transplant a cutting to be done bigger and with the ccontaining cover 22 movable plug-in mountings of pedestal 2, scraping blade 4 also can be formed swings back and forth.
