Description

The movable fastener of case

Technical field

The utility model relates to a kind of mechanical component, especially a kind of fastener that makes things convenient for casing to open, the movable fastener of specifically a kind of case.

Background technology

In real work, that people often run into is unpacking, close the action of case, it is hinged that existing casing is connected to a side, opposite side then adopts a kind of assembly that is called strike to connect, it is antitheft to close the back lockable, and this connection mode need frequently be opened, fasten and need not just to seem impracticable for the theft-proof casing for those.

Summary of the invention

The purpose of this utility model is a kind of folding with convenience of design, compresses the movable fastener of failure-free case.

The technical solution of the utility model is:

The movable fastener of a kind of case, by linking to each other and form with upper and lower case lid contacted upward button 1, lower fastener 2 respectively, it is characterized in that button 1 is provided with out button window 3, the bottom of opening button window 3 is provided with and the last button 1 whole reed 4 that links to each other, the other end of reed 4 sticks up and leaves button window 3, and reed 4 is provided with and the contacted step surface 5 of upper box lid; The bottom integral body of lower fastener 2 is connected with hook sheet 6, and hook sheet 6 and reed 4 lay respectively at two sides of the fastener body of being made up of last button 1 and lower fastener 2.

Last button 1 links to each other with lower fastener 2 by transition body 7, and the angle α between transition body 7 and the lower fastener 2 is less than 180 degree, and greater than 90 degree, the angle β between transition body 7 and the last button 1 is also less than 180 degree, greater than 90 degree.

The beneficial effects of the utility model:

1, simple in structure, easily manufactured, can adopt the mode once-forming of punching press.

2, compress reliably, open conveniently, during use as long as reed is pulled to button gently can make case lid separate with casing, during fastening only need the step surface on the reed be pressed on the case lid get final product.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described.

As shown in Figure 1, 2.

The movable fastener of a kind of case, by linking to each other and form with upper and lower case lid contacted upward button 1, lower fastener 2 respectively, last button 1 links to each other with lower fastener 2 by transition body 7, angle α between transition body 7 and the lower fastener 2 is 160 degree, angle β between transition body 7 and the last button 1 also is 160 degree, going up button 1, transition body 7, lower fastener 2 during concrete the manufacturing be the continuous structure of integral body that whole punching press forms, as shown in Figure 1.Last button 1 is provided with out button window 3 (as Fig. 2), and the bottom of opening button window 3 is provided with and the last button 1 whole reed 4 that links to each other, and the other end of reed 4 sticks up and leaves button window 3, and reed 4 is provided with and the contacted step surface 5 of upper box lid; The bottom integral body of lower fastener 2 is connected with hook sheet 6, and hook sheet 6 and reed 4 lay respectively at two sides of the fastener body of being made up of last button 1 and lower fastener 2.

The utility model can adopt spring steel to be stamped to form, and its length and width can be decided according to concrete box sizes, and angle α, β can choose between 90～180 degree.

Fig. 3 is the utility model running condition structural representation.Fastener of the present utility model inserts in the metal jack 10,11 that protrudes from casing 9 and case lid 8 sides, and wherein hook sheet 6 hooks the bonding jumper on the casing 9, and the step surface 5 on the reed 4 is pressed on the upper surface of case lid 8.When needs are opened case lid, can press reed 4 in the direction of arrows, the step surface 5 on the reed 4 is separated with the upper surface of case lid 8, case lid 8 can separate with casing 9, otherwise then case lid 8 and casing 9 can be compressed.
