Comprise among Fig. 1 and Fig. 2:
1---body;
2---buckle;
21---grab;

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
See illustrated in figures 1 and 2, a kind of engine cleading described in the utility model, comprise body 1, described body 1 is provided with buckle 2, described buckle 2 front ends convex with grab 21, described buckle 2 convexes with a pair of card base 22, is provided with deformation gap 23 between the described card base 22, and described grab 21 is convexly set in described card base 22 front ends respectively.
The utility model is when assembling, described grab 21 is subjected to the extruding of draw-in groove cell wall and moves in described deformation gap 23, and deflection takes place in drive card base 22 in the elastic deformation weight range, after grab 21 enters draw-in groove, the resilience under self reseting elasticity effect of described card base 22, thereby grab 21 is rebounded, and the step surface of grab 21 contacts with the draw-in groove inwall and is restrained, thereby finishes assembling.Owing to be provided with card base 22, described grab 21 forms cantilever design, and action radius is big, and buckle 2 elasticities are good, easy to assembly, and buckle 2 is difficult for deforming in fitting process, and assembly performance is good; Owing to be provided with deformation gap 23 between a pair of card base 22, buckle 2 distortion allowances are big, and are good to the cyclic deformation comformability of engine cleading body 1 in the working process, and the connective stability height makes the engine cleading be difficult for becoming flexible or coming off.
Preferably, the length of card base 22 described in the utility model is not less than 3 times of described grab 21 length, and is not more than 5 times of described grab 21 length.If card base 22 length are too short, then card base 22 formed cantilevers are short, and amount of elastic deformation is little, thereby makes the moving range of grab 21 little, is unfavorable for assembling; If card base 22 length are long, then card base 22 self intensity reduces, and easily fractures in the flexure deformation process; So the utility model is provided with 3～5 times scopes of the length of described card base 22 in grab 21 length, has both guaranteed the assembling convenience, has guaranteed buckle 2 structural strengths again, thereby has guaranteed the installation reliability of engine cleading.
See shown in Figure 2ly, described card base 22 has extended strengthening rib 24 towards the lateral margin of described deformation gap 23.The side lateral margin of described strengthening rib 24 along described card base 22 towards described deformation gap 23 is provided with, and strengthened the structural strength of card base 22 when flexure deformation, improved assembling of the present utility model and functional reliability.Wherein, described card base 22 can adopt integrated processing mode preparation with strengthening rib 24.
Wherein, the strengthening rib 24 of two described card bases 22 is extending in opposite directions near card base 22 root places and is interconnecting, thereby forms a root strengthening rib 25 in described deformation gap 23 bottoms.Like this, the strengthening rib 24 of two card bases 22 forms whole by described root strengthening rib 25, has further improved the structural strength of described card base 22.
Wherein, described strengthening rib 24 forms arc angling with the angle of root strengthening rib 25.In the flexure deformation process of described card base 22, described strengthening rib 24 is an areal of stress concentration with the angle of root strengthening rib 25, the setting of described arc angling, the edge that makes strengthening rib 24 along the edge that transits to root strengthening rib 25 with sliding no catastrophe point, thereby avoided the appearance of focal point of stress, disperse stress, improved structural strength.
Wherein, described strengthening rib 24 front ends extend to the cooresponding zone of described grab 21 lateral margins, and strengthening rib 24 front ends do not stretch out described grab 21 front ends.In the card base 22 stressed flexure deformation processes, its front end, be that the cantilever end deflection degree is big, stress is little, so its strengthening rib 24 front ends extend to the cooresponding zone of described grab 21 lateral margins, and do not stretch out described grab 21 front ends, the one side economical with materials, make card base 22 front portions be easy to flexure deformation on the other hand, help finishing assembling.
Wherein, the position of described strengthening rib 24 anterior certainly close described grabs 21 to the width of strengthening rib 24 front ends reduces gradually.As mentioned above, the strengthening rib 24 that reduces gradually of anterior width helps card base 22 anterior flexure deformation and economical with materials.
Wherein, the lateral edges line of described strengthening rib 24 is the lateral edges line along sliding no catastrophe point.Avoided the catastrophe point place of stress concentration like this, the assembly reliability and the service life of having improved this engine cleading in the lateral edges line.
Wherein, described card base 22 roots form the pin base 221 that width increases.In assembling and the working process, card base 22 roots are delivery areas and areals of stress concentration of power, and the setting of described pin base 221 has improved the structural strength of card base 22 roots and then the assembly reliability and the service life of having improved this engine cleading.
The above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
