Chain saw air filter is as a kind of important composition parts of chain saw, and being mainly used in provides clean air to improve efficiency of combustion to the combustion system of chain saw.Before use, operating personnel need carry out cleannes inspection to air filter.In use, every use is after 25 hours, and operating personnel need to carry out dust removal processing to air filter, and in the large operating environment of dust, operating personnel must carry out dust removal processing more continually.If when the phenomenons such as oiling is flame-out, operation power reduction, engine overheat appear in chain saw, operating personnel also need air filter to check.Therefore operating personnel need to open and close air filter continually, and this mode that just requires to open, close chain saw air filter lid is quick and easy.
In prior art, chain saw air filter cover locking device comprises snap close, draw-in groove and key seat, and the mode connecting with interference is by air filter cover locking, and snap close is directly connected by bearing pin with key seat.This connected mode needs operating personnel to use instrument to knock snap close could to be pressed in draw-in groove, also to need operating personnel to use the instruments such as ripping bar just can make snap close deviate from from draw-in groove, thereby makes frequently opening or closing of chain saw air filter lid very inconvenient.In actual job process, chain saw air filter cover locking device of the prior art is not only loaded down with trivial details and consuming time in operation, and after suffering frequent gravity to knock and lever up, snap close is easily out of shape, and even can make locking device lose efficacy when serious.
Therefore, those skilled in the art be devoted to develop a kind of without by instrument, can directly lock or open and Reusability after can not be out of shape the chain saw air filter cover locking device even losing efficacy.
Utility model content
Because the above-mentioned defect of prior art, technical problem to be solved in the utility model be to provide a kind of without by instrument, can directly open or close and Reusability after can not be out of shape the chain saw air filter cover locking device even losing efficacy.For achieving the above object, the utility model provides a kind of chain saw air filter cover locking device of realizing locking function by lever principle.
Chain saw air filter cover locking device provided by the utility model comprises rocking arm, snap close, draw-in groove and the key seat corresponding with snap close; Wherein said key seat is fixed on chain saw upper cover plate, and one end of described rocking arm and described key seat are hinged, and the other end of described rocking arm and the first end of described snap close are hinged; Described draw-in groove is arranged on chain saw air filter and covers, and the second end of described snap close is optionally connected in described draw-in groove.Like this, compare with locking device of the prior art, between snap close and key seat, installed the rocking arm that plays leverage additional, thereby not need by instrument with regard to available hand directly by snap close by compressing into draw-in groove, realize locking function, or snap close is extracted in draw-in groove, open locking device.
Operation principle of the present utility model is based on lever principle, with hand, described snap close is pulled out outward, makes it depart from draw-in groove, and carries to draw-in groove top, can open chain saw air filter cover locking device; With hand, described snap close is pressed downwards, it is moved down, when snapping into groove position, Dacca, firmly press down snap close, make itself and draw-in groove chimeric, can lock chain saw air filter cover locking device.
In better embodiment of the present utility model, described draw-in groove both sides are provided with the locating part that prevents that snap close from moving left and right, and preferably limiting plate, is fastenedly connected snap close and draw-in groove, when chain saw is worked, not because its excessive causing of vibrations gets loose.
In another better embodiment of the present utility model, described snap close is arc on the whole, and holding area is designed according to body mechanics, laborsaving and comfort level good.
In another better embodiment of the present utility model, on described snap close, there is outstanding press handle, easy operating while pressing.
In another better embodiment of the present utility model, described rocking arm is elastic plastic member.
In another better embodiment of the present utility model, described second end of described snap close is barb-shaped, and described draw-in groove is corresponding hook flute profile, and in violent operation process, snap close can not deviate from from draw-in groove.
In another better embodiment of the present utility model, described snap close is elastic plastic member, has larger toughness and tensile strength, guarantees can not rupture under violent vibrations, due to stressed little, through extracting frequently and pressing, can not be out of shape.
In another better embodiment of the present utility model, described draw-in groove and chain saw air filter are covered the part that is formed in one.
In another better embodiment of the present utility model, described key seat and the chain saw upper cover plate part that is formed in one.
Technique effect
The chain saw air filter cover locking device that the utility model provides is realized locking function by lever principle, opens or closes, and after repeated multiple times use, there will not be failure phenomenon without can directly realizing by instrument.
Below with reference to accompanying drawing, the technique effect of design of the present utility model, concrete structure and generation is described further, to understand fully the purpose of this utility model, feature and effect.
Accompanying drawing explanation
Fig. 1 is the partial schematic diagram of chain saw that is equipped with the chain saw air filter cover locking device of a preferred embodiment of the present utility model, and wherein chain saw air filter cover locking device is in locking state;
Fig. 2 is the A-A cross-sectional view in Fig. 1;
Fig. 3 is the local enlarged diagram of the chain saw air filter cover locking device in Fig. 2;
Fig. 4 is chain saw air filter cover locking device in Fig. 3 structural representation in open mode.
The specific embodiment
As shown in Figure 1, Figure 2 and Figure 3, in a preferred embodiment of the present utility model, chain saw air filter cover locking device comprises rocking arm 6, snap close 3, draw-in groove 2 and the key seat 8 corresponding with snap close 3.Key seat 8 is fixed on the upper cover plate 7 of chain saw, and rocking arm 6 is nylon PA66 working of plastics, and there is respectively a pin-and-hole 5 at its two ends, wherein pin-and-hole 5 is passed by bearing pin in one end, rocking arm 6 is hinged on key seat 8, and the other end passes pin-and-hole 5 by bearing pin, hinged with the first end of snap close 3; Draw-in groove 2 is arranged on chain saw air filter lid 1, and key seat 8 is arranged on chain saw upper cover plate 7.
