Preferably, said lock set comprises a substrate, and the latch hook of a hook is set on the said substrate leading flank, corresponding, said box is provided with a hook plate on one's body, and said latch hook is hooked on the said hook plate.

Preferably, a through hole is set on the vertical direction on the said substrate, said lock set is connected through threaded fastener with said box body.

Preferably, said lock set also comprises a spring, and horizontally set one column on the side of said substrate, said spring housing are connected with the cell wall elasticity of said box body on said column.

Preferably, the natural length of said spring is greater than the length of said column.

Preferably, said lock set is arranged on the top of said box body.

Owing to adopted above technical characterictic, made the utility model have following advantage and good effect than prior art:

The utility model provides a kind of instrument cases of fixedly open angle, and lid is connected with box body hinge, is provided with block in this hinge link lower end; Open the lid; Be close to block until lid, lid just can not continue to launch again, and promptly lid can only be opened fixed angle so far; In the box body groove of the utility model a lock set is set also, instrument cases are under closure state, and lock set is connected lid with the box body, play the fixed connection effect.

In sum, the utility model is simple in structure, and is easy to operate;

On the one hand, lid has the function that is opened to certain angle, makes things convenient for picking and placeing of instrument, reduces the floor space under the instrument cases open mode;

On the other hand, lid has the second heavily lock effect.At opening part, lid and box body itself are provided with the buckle syndeton, lose efficacy in order to prevent buckle; Also be provided with lock set, even buckle lost efficacy, through lock set being connected with lid and box body; Lid still is fastenedly connected and locks with the box body, and lock set plays the effect of double insurance.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is described in detail.

Please refer to Fig. 1, a kind of instrument cases of fixedly open angle comprise lid 1 and box body 2; In the junction, lid 1 is connected through the hinge with box body 2, promptly on the limit of lid 1 and box body 2, convexes with connector respectively; All be provided with through hole on the connector, pass the through hole connection that pivots successively through pin 3; At opening part, lid 1 is connected with box body 2 buckles.Centre position at opening part also is provided with handle 22, and this handle 22 is arranged on the box body 2.In handle 22 both sides, a clamp 23 is set respectively, corresponding, being fixedly connected with buckle 11 on the lid 1 with hook structure 111, during with lid 1 closure, buckle 11 just has been hooked on the clamp 23, plays the effect that is fastenedly connected.

Please refer to Fig. 2 and Fig. 3, the position in the junction is provided with block 4 on box body 2, and this block 4 is arranged on the lower end, junction, and promptly this block 4 is arranged on the joint face of box body 2.One slope 41 is set on this block 4; This slope 41 is from top to bottom along sliding; Get off from the outside slope of joint face in the upper end that is this block 4, this slope 41 is an acute angle with the angle a of box body 2 sides, and the utility model does not limit the concrete angle of this angle a; In the present embodiment, so acute angle is 68 °.Open the lid 1, in 1 the process of opening the lid, the side of lid 1 does not also have to fit with the slope of block 4.Please refer to Fig. 4 and Fig. 5, under the lid full open position, promptly when lid 1 opened to 112 °, block 4 was close to lid 1, and at this moment, block 4 has stopped the expansion campaign of lid 1.Because the angle that lid 1 is opened is greater than 90 °, so, need not to worry that lid 1 can fall down in the position of this fixed angle, the people accidentally, lid 1 closure of instrument cases can cause the phenomenon of damage personnel or instrument etc. to take place.

Please refer to Fig. 6, Fig. 7, Fig. 8 and Fig. 9, the utility model also is provided with a lock set 5.Comprise some grooves in the box body 2, in the groove apart from the top of box body 2, a lock set 5 is set, the effect of lock set 5 is, when lid 1 was closed, lock set 5 was connected lid 1 and both are locked together with box body 2, has second effect of heavily locking.Under the situation that two buckles of handle 22 both sides 11 lost efficacy, guarantee that lid 1 still is in closure state, play the effect of double insurance.This lock set 5 comprises a substrate 51, and the latch hook 511 of a hook is set on the leading flank of substrate 51.In the utility model, this latch hook 511 is formed a hook structure by two mutually perpendicular plates, on the position of corresponding latch hook 511, a hook plate 12 is set on the box body 2, and when lid 1 closure, latch hook 511 is hooked on the hook plate 12.The upper end in the vertical direction of substrate 51 is provided with a through hole 513, and lock set 5 is to pierce in this through hole 513 through threaded fastener 6 with being connected of box body 2, lock set 5 is fixedly connected on the cell wall of box body 2.Lock set 5 also comprises a spring 52, horizontally set one column 512 on the side of substrate 51, and this column 512 is cylindrical, and spring 52 is under nature, and the length of spring 52 is greater than the length of column 512.This spring 52 is enclosed within on the column 512 and is connected with the cell wall elasticity of box body 2, prevents that lock set 5 from rocking in box body 2.

More than a disclosed specific embodiment that is merely the application, but the application is not limited thereto, any those skilled in the art can think variation, all should drop in the application's the protection domain.
