Description
Technical field
The utility model relates to a kind of snap close, particularly relates to a kind of replaceable automobile engine cover snap close.
Background technology
Automobile engine cover snap close is a security insurance part, uses medium carbon steel through heat treatment to ensure enough toughness and abrasion resistance.Connect firmly on bonnet sheet metal component mainly through welding or riveted joint at present.Welding easily causes the bad defects such as the annealing of medium carbon steel snap close, crackle; Moreover, no matter welding or riveted joint, if bonnet snap close wearing and tearing excessive exist potential safety hazard need change time, then must change overall bonnet, cause significant wastage.Under this kind of background, be badly in need of the bonnet snap close that the simple and easily changeable bonnet snap close of a kind of structure substitutes welding or riveted type.
Utility model content
Technical problem to be solved in the utility model is to provide the simple and easily changeable replaceable bonnet snap close of a kind of structure.
In order to solve the problems of the technologies described above, the replaceable bonnet snap close that the utility model provides, comprise snap close, nut, positioning and guiding cover and fixed head, two front ends of described snap close are equipped with step, described step front end on described snap close is provided with chamfering, the back segment described snap close being in described step is provided with screw rod, described snap close is provided with the nut screwed with described screw rod, the side of described fixed head is provided with positioning and guiding cover, described positioning and guiding cover spot welding is fixed on described fixed head, the lower end of described positioning and guiding cover is provided with chamfering, described fixed head is provided with through hole, described snap close pushes in the hole that described positioning and guiding overlaps from the opposite side of described fixed head by the top bar chamfering through hole be guided through fixed head of front end of described snap close again, upwards screw the described nut be enclosed within described screw rod, described nut under the guiding of the chamfering of the lower end that described positioning and guiding overlaps along the bottom cylindrical of described positioning and guiding cover continue to rotate up until rotate motionless till and snap close described in fixing and locking.
The front end of described nut is unthreaded hole, and rear end is the screw thread screwed with described screw rod.
Described fixed head is provided with reinforcing rib.
Described positioning and guiding cover point is welded on described fixed head.
Described step front end on described snap close is provided with chamfering.
The lower end of described positioning and guiding cover is provided with chamfering.
Adopt the replaceable bonnet snap close of technique scheme, be characterized in: 1, no longer weld, avoid in the snap close welding process requiring toughness and abrasion resistance to take into account and cause the bad defects such as annealing, crackle; If 2, wear and tear in snap close use procedure excessive exist potential safety hazard need change time, overall bonnet need not be scrapped, as long as change slight snap close, remarkable in economical benefits; 3, mounting or dismounting are convenient.
In sum, the utility model is the simple and easily changeable replaceable bonnet snap close of a kind of structure.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
See Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, two front ends of snap close 1 are equipped with step 5, and back segment snap close 1 being in step 5 is provided with screw rod 6, and snap close 1 is provided with the nut 2 screwed with screw rod 6, positioning and guiding overlaps 3 spot welding and is fixed on fixed head 4, and fixed head 4 is provided with through hole 8.During use, snap close 1 is pushed positioning and guiding from the opposite side of fixed head 4 again overlapped in the hole of 3 by top bar chamfering 9 through hole 8 be guided through fixed head 4 of 5 front ends of snap close 1, upwards screw the nut 2 be enclosed within screw rod 6, nut 2 under the guiding of the chamfering 10 of the lower end of positioning and guiding cover 3 along the bottom cylindrical of positioning and guiding cover 3 continue to rotate up until rotate motionless till and snap close 1 described in fixing and locking.
Preferably, step 5 front end on snap close 1 is provided with chamfering 9, makes snap close 1 can pass through through hole 8 on fixed head 4.
Preferably, the lower end of positioning and guiding cover 3 is provided with chamfering 10, makes positioning and guiding overlap 3 and can import smoothly in the unthreaded hole of nut 2.
Preferably, the front end of nut 2 is unthreaded hole, and rear end is the screw thread screwed with screw rod 6, makes nut 2 can adapt to fixed head 4 and the positioning and guiding cover 3 of different-thickness.
Fixed head 4 is provided with reinforcing rib 7, adds the strength and stiffness of fixed head 4.
See Fig. 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5, snap close 1 need not weld or rivet and connect firmly on bonnet sheet metal component and fixed head 4, avoids in the snap close welding process requiring toughness and abrasion resistance to take into account and causes the bad defects such as annealing, crackle; If wear and tear in snap close 1 use procedure excessive exist potential safety hazard need change time, overall bonnet need not be scrapped, as long as change slight snap close 1, remarkable in economical benefits; Structure is simple, and mounting or dismounting are convenient.
