Detailed description of the invention

In order to enable better technical scheme to be understood, below by specifically embodiment and be described in detail in conjunction with accompanying drawing:

Referring to Fig. 1 and Fig. 2, a kind of workbox with the anti-latch mechanism that jolts, including instrument casing and latch mechanism.

Instrument casing, supports stator 44 under 43 gentle supports including upper cover 11, casing 41, the upper stator 13 of gas support, gas; Upper cover 11 passes through hinge in the outside of the rear wall of casing 41; The upper stator 13 of gas support is welded in the inner side of upper cover 11; The lower stator 44 of gas support is welded in the inner side of the rear wall of casing 41; The two ends of gas support 43 connect stator 44 under the upper gentle support of stator 13 of gas support respectively.

Latch mechanism, including lock set, lock pin 23, locking bar 31, locking bar prerotation vane 33, locking bar stator 12, latch hook 32, latch hook torsion spring 34 and lock hook shaft 42.

Lock set, connects axle 22 and lock handle 24 including lock panel 21, locking bar; Lock handle 24 be arranged on lock panel 21 on the face outside upper cover 11; Locking bar connects axle 22 and is arranged on the both sides of lock panel 21; Locking bar 31 connects axle 22 traverse lock set by locking bar. Lock set is arranged on upper cover 11.

Locking bar 31 is through lock set, and is locked by lock pin 23. Two locking bar prerotation vanes 33 are each passed through the two ends of locking bar 31, and locking bar prerotation vane 33 is connected with locking bar stator 12 by screw, and locking bar stator 12 is welded on the inner side of upper cover 11. The two ends of locking bar 31 are respectively welded a latch hook 32. Being trapped of latch hook torsion spring 34 is connected on locking bar 31, is positioned at the inner side of the outside of locking bar prerotation vane 33, latch hook 32, and the end of latch hook 32 is fixed in one end of latch hook torsion spring 34, and the other end is fixed on upper cover 11.

Lock hook shaft 42 is symmetricly set on the inner side of two sidewalls of casing 41.The hole being used for installing lock hook shaft 42 on casing 41 is bar hole. Adopting such design, it is possible to regulate the position of lock hook shaft 42, make upper cover 11 when closing, latch hook and lock hook shaft agree with the tightst, thus obtaining the workbox sealing effect of the best.

When closing upper cover, the inclined-plane of the hook portion of latch hook 34 first touches lock hook shaft 42, and then latch hook 34 opens along inclined-plane to external rotation, until the hook portion of latch hook 34 snaps in lock hook shaft 42, upper cover 11 i.e. lockable. Due to the twisting force of latch hook torsion spring 34, the end of latch hook 32 contacts with upper cover 11 all the time, it is ensured that the position angle of latch hook 32, under the environment jolted latch mechanism can be played important Stabilization.

A kind of workbox with the anti-latch mechanism that jolts of the present invention can in the process of transport, effectively resist the harmful effect that the stability of the seal to workbox and latch mechanism of jolting causes, ensure the performance in workbox under severe traffic condition, simple in construction, uses and keeps in repair very convenient simultaneously.

Those of ordinary skill in the art will be appreciated that, above embodiments is intended merely to the explanation present invention, and it is not used as limitation of the invention, as long as in the spirit of the present invention, to the change of embodiment described above, modification all by the Claims scope dropping on the present invention.
