While adopting simple Spielpassung form, jump ring easily assembles, but jump ring easily comes off on cylinder, is equally also easily subject to spatial constraints to affect jump ring and assembles.
Summary of the invention
The problem that the present invention exists for solving prior art, can carry out the spacing easily gripping mechanism of assembling, difficult drop-off of realizing to jump ring thereby provide a kind of, and it is simple in structure, easily realizes.
The present invention is achieved by the following technical solutions:
An air filter upper-lower casing gripping mechanism, includes jump ring and overlap joint piece;
One end of described jump ring is with the block tongue clamping of the upper shell of air filter, and the other end is flexibly connected with overlap joint piece; Described overlap joint piece is fixed on the nearly upper end of air filter lower shell body;
Described jump ring is for having flexible arcuate structure, and the one end being wherein connected with overlap joint piece is for being provided with U groove, and the curling two cirque structures for not sealing of the direction identical with the radian direction of jump ring;
One end of the block tongue clamping of described jump ring and air filter upper shell is bent to form handle to the direction of the arcuate opposite with jump ring, for opening gripping mechanism;
The position of the block tongue clamping of described jump ring and air filter upper shell is provided with curved part, and the radius of curvature of described curved part is less than the radius of curvature of jump ring radian;
Described overlap joint piece has three vertical blocks, and wherein, middle vertical block outer end is provided with L-type breach, on described overlap joint piece, is provided with and crosses cylindrical body, and described cylindrical body is through two cirque structures of jump ring, as the coupling shaft of overlap joint piece and jump ring.
The jointing place of the described pair of cirque structure and jump ring is and the curved section of jump ring arcuate opposite that the radius of curvature of described curved section is greater than the radius of curvature of the radian of jump ring.
In three vertical blocks of described overlap joint piece, the thickness of middle vertical block is less than the thickness of other two vertical blocks, and its thickness is less than the U well width of jump ring.
The limit structure that described L-type breach is jump ring.
The distance of not sealing opening of the described two cirque structures that do not seal is less than cylindrical diameter.
The invention has the beneficial effects as follows:
Air filter upper-lower casing gripping mechanism provided by the invention is when filter core cleaning or replacing, jump ring easily operates at institute extreme position place, during fastening, there is no clamping stagnation sense, no matter be that jump ring is opened or fastening, difficult drop-off all under the effect that there is no artificial external force utilizes structure simple and that easily realize to solve the problem that jump ring easily assembles difficult drop-off simultaneously.

Fig. 3 be Fig. 1 jump ring while opening by gripping mechanism A-A to partial sectional view;
Fig. 4-Fig. 7 is that gripping mechanism is assembled to by jump ring the process schematic diagram that jump ring is opened.
Embodiment
Describe by the following examples technological scheme of the present invention in detail, following embodiment is only exemplary, only can be used for explaining and technological scheme of the present invention being described, and can not to be interpreted as is the restriction to technical solution of the present invention.
As shown in Figures 1 to 7, a kind of air filter upper-lower casing gripping mechanism, described gripping mechanism 2 is arranged in air filter 1, between the upper shell 5 of air filter 1 and lower shell body 8, be provided with filter core Stamping Steel Ribbon 6 and filter core frame 7, filter core is placed into after air filter, put down after upper shell, in the middle of upper shell and lower shell body, accompany filter core Stamping Steel Ribbon and filter core frame, then with gripping mechanism, clamp.
Described gripping mechanism 2 includes jump ring 3 and overlap joint piece 4;
One end of described jump ring 3 is with block tongue 13 clampings of the upper shell of air filter, and the other end is flexibly connected with overlap joint piece 4; Described overlap joint piece 4 is fixed on the nearly upper end of air filter lower shell body 8;
Described jump ring 3 is for having flexible arcuate structure, and the one end being wherein connected with overlap joint piece 4 is for being provided with U groove, and the curling two cirque structures for not sealing of the direction identical with the radian direction of jump ring;
One end of block tongue 13 clampings of described jump ring 3 and air filter upper shell 5 is bent to form handle 9 to the direction of the arcuate opposite with jump ring, for opening gripping mechanism;
Described jump ring 3 is provided with curved part 10 with the position of block tongue 13 clampings of air filter upper shell 5, and the radius of curvature of described curved part 10 is less than the radius of curvature of jump ring radian;
