Description

Cover safety lock before the automobile

The utility model relates to a kind of lockset, specifically is meant a kind of safety lock of locking preceding cover of automobile or fastening heavy goods vehicles driving building.

At present, the device of cover is the two ends that utilize the metal extension spring before the general automobile that uses, be separately fixed on lock body, the lock hook, the off-centre that relies on the position, hold the snap close of the preceding cover of automobile, though between lock and cover, also done insurance, but in the automobile actual travel, the situation that often has the preceding cover of automobile to be opened by the top.Automotive security that other has lock is though the patent No. is 93212014.8 to have solved the problems referred to above, the defective below existing, the one, the later problem of damage of components is not taken into account, the 2nd, the vertical rotation of location lock, engaged position is too big, the 3rd, special-purpose cable friction is big, and can not reset.

Goal of the invention of the present utility model is that the classification according to vehicle discloses cover safety lock before a kind of safe and reliable, the easy to use automobile.

Realize that technical solution of the present utility model is as follows: go up by axis (3) riveted joint lock hook (1) at lock body (2), guide pin bushing (10) is arranged in the axis (3), there is packing ring (14) assembling ratchet (9), be provided with switch spring (4) between lock hook (1) and the axis (3), be fixed with guide pin bushing (7) on the lock hook (1), be provided with compression spring (6) and alignment pin (5) in the guide pin bushing (7), lock body (2) is gone up and the correspondence position of the alignment pin (5) of lock-out state has an open pore (16), guide pin bushing (7) one sides are provided with the resetting means that makes alignment pin (5) displacement, have on lock body (2) and the lock hook (1) and can make corresponding breach (17) that cover is pressed into when cover before the automobile is pressed down by opening, be pressed into through breach (17), and lock hook (1) is rotated around axis (3), guide pin bushing (7) rotates to certain position simultaneously, and compression spring (6) makes alignment pin (5) displacement and locks corresponding perforate on the cover by open pore (16).When need are opened cover, only need to start the resetting means that makes alignment pin (5) displacement of guide pin bushing (7) one sides, alignment pin (5) withdrawal, and under the effect of switch spring, lock hook (1) rotation then is an opening.

Structure of the present utility model is very simple, and is easy to use, and locked secure is reliable, all can not run through test cover before various road conditions situation automobiles and hold.

Provide embodiment of the present utility model below in conjunction with accompanying drawing.

Accompanying drawing is an enforcement of the present utility model structural representation just.

Referring to accompanying drawing, the structure of embodiment is as follows: go up by axis (3) riveted joint lock hook (1) at lock body (2), be provided with switch spring (4) between lock hook (1) and the axis (3), switch spring (4) is fixed on the axis (3) spring one end, one end is fixed on the lock hook (1), lock hook (1) is one can be around the revolving meber of axis (3) rotation, be fixed with guide pin bushing (7) on the lock hook (1), be provided with compression spring (6) and alignment pin (5) in the guide pin bushing (7), alignment pin (5) correspondence position of deciding state with pin on the lock body has an open pore (16), and guide pin bushing (7) one sides are provided with the resetting means of the displacement that makes alignment pin (5).Above-mentioned resetting means is the moving bar (8) of an approximate U-shaped, one end of U-shaped moving bar (8) is provided with a back-moving spring (11) and backguy (18), the moving bar of U-shaped (8) is arranged in the bar hole on the lock body (2) by the axis of guide (13) packing ring (12), moving bar (8) can displacement in bar hole, when cover before the automobile is lock-out state, there is a projection that is connected with alignment pin (5) rear end of guide pin bushing (7), the overlapped part of an end of itself and U-shaped moving bar (8).When the pulling backguy, U-shaped moving bar (8) is to left dislocation, and the projection by guide pin bushing (7) rear end makes alignment pin (5) to left dislocation simultaneously, then makes lock-out state transfer opening to.For further improving locking effect, upward assembling ratchet (9) at lock body (2) by axis (3), be provided with an extension spring (15) between the other end of ratchet (9) and the lock body (2), when cover presses down, ratchet (9) can with right snap close interlock mutually on the cover, further lock cover, under the effect of extension spring (15), ratchet can rotate around axis (3), and then locking cover or unlatching.
