Description

A kind of heavy truck mask lock construction

Technical field

The utility model relates to technical field of automobile accessories more particularly to a kind of heavy truck mask lock constructions.

Background technique

Domestic and international most of heavy trucks are each equipped with openable radiator grille, for overhauling front wall components and avoiding Interference is generated with front bumper during driver's cab turnover.Radiator grille lock body is for keeping radiator grille to be in long-term closed state. In currently used clamp plate type radiator grille lock body structure, often there is the case where wire drawing abjection, cause radiator grille surprisingly open or The failure of person's wire drawing unlocking function；In addition, above-mentioned clamp plate type radiator grille lock body structure is during with latch engagement, lock can with it is preceding Mask lock bottom plate mutually collides, and generates abnormal sound, and the zinc coat on bottom plate is easy to cause to fall, corrosion problem occurs.In addition, Structure is complicated for mask latch mechanism, price, weight are unfavorable for greatly lightweight.Common mask latch mechanism includes executing agency, lock Tight mechanism, opener etc..Cooperation between each mechanism corresponding in this way requires very high.Meanwhile each mechanism will cloth A position is set, arrangement difficulty is increased.

Summary of the invention

It is existing in the prior art to solve the purpose of this utility model is to provide a kind of automobile radiator grille lock body assembly Problem, concrete scheme are as follows:

Heavy truck mask lock construction includes mask lock and mask lock support；Mask lock includes circlip, mask tapered end, return bullet Spring, mask lock pin；Mask lock support includes u-bracket elastic slice, u-bracket, buffer stopper and rivet；Mask lock passes through fixture nut It is fixed on mask with nut red steel circle；Mask lock support is fixed on cab floor branch by support bracket bolt and support nut Frame；Mask lock is combined with key；When closing, on the mask lock pin and mask lock support that heavy truck mask lock construction is locked by mask The locking of u-bracket elastic slice；When unlatching, mask lock is inserted by the key, is rotated by 90 ° counterclockwise, mask lock pin struts U-shaped branch It is opened after frame elastic slice.

Further, u-bracket elastic slice is fixed in u-bracket by rivet, u-bracket elastic slice and the u-bracket On be provided with corresponding through-hole, through-hole is that mask locks pin insertion hole；Support bracket bolt and support nut installation are provided in u-bracket Hole.

The utility model has the beneficial effect that opener and executing agency, which are merged simplification, realizes shirtsleeve operation, Opening ways are simplified, while driver being facilitated usually to open mask maintenance；Arrangement be easy, reduce part weight and at This.

Specific embodiment

Referring specifically to Figure of description 1-6, the technical solution of the utility model is described further.

Heavy truck mask lock construction includes mask lock 1 and mask lock support 2；Mask lock 1 include circlip 11, mask tapered end 12, Return spring 13, mask lock pin 14；Mask lock support 2 includes u-bracket elastic slice 21, u-bracket 22, buffer stopper 23 and rivet 24；Mask lock 1 is fixed on mask 7 by fixture nut 5 and nut red steel circle 4；Mask lock support 2 passes through 3 He of support bracket bolt Support nut 8 is fixed on cab floor bracket 6；Mask lock 1 is combined with key 9；When closing, heavy truck mask lock construction passes through face U-bracket elastic slice 21 on the mask lock pin 14 and mask lock support 2 of cover lock 1 is locked；When unlatching, mask is inserted by key 9 Lock 1, is rotated by 90 °, mask lock pin 14 is opened after strutting u-bracket elastic slice 21 counterclockwise.After unlatching, mask lock 1 can restore automatically To initial position, guarantee the normal switching-off of mask lock 1 next time.

7 on mask, then mask lock 1 is fixed to by specific description by fixture nut 5 and nut red steel circle 4 first It is fixed on cab floor bracket 6,2 assembly of mask lock support finally by mask by support bracket bolt 3 and support nut 8 Lock 1 and mask lock support 2 are locked by bracket elastic slice 21.The mode for starting mask is that key 9 is inserted into mask lock 1, inverse time After needle is rotated by 90 ° unlatching unlatching, mask lock 1 can automatically restore to initial position.The utility model is by opener and executes machine Structure, which merges simplification, realizes shirtsleeve operation, simplifies opening ways, while driver being facilitated usually to open mask maintenance；Cloth It is easy to set, and reduces the weight and cost of part.

The preferred embodiment of the patent is described in detail above, but this patent is not limited to above-mentioned embodiment party Formula within the knowledge of one of ordinary skill in the art can also be under the premise of not departing from this patent objective Various changes can be made.
