Abstract

The utility model provides an iron case which comprises a case body and a case cover. The corresponding edges of the case cover and the case body are provided with frames which are parallel to each other. The frames are provided with magnets flush with the upper planes of the frames. The frames of the case cover are provided with protrusive locating pins, and the frames, corresponding to and making contact with the frames of the case cover, of the case body are provided with corresponding locating holes. According to the iron case with the structure, the case cover and the case body cannot move in a parallel mode after the locating pins are inserted into the locating holes, the case cover is attracted to the case body under the action of the magnets, and the case cover can be installed on and connected to the case body conveniently. When needing to be detached, the case cover can be separated from the case body after overcoming the attraction force of the magnets by applying force vertically, and the case cover can be taken down conveniently.

Description

A kind of iron sheet case

Technical field

The utility model relates to a kind of iron sheet case, particularly the separable iron sheet case of a kind of case lid and casing.

Background technology

The iron sheet case has a wide range of applications, and casing adopts the parts such as hinge, buckle, lockset to be connected with case lid usually, but case lid integral body need to be taken off in some application scenarios, and aforesaid way is not too convenient; Also have in addition some case lids to adopt a side that hinge is installed, an other side adopts the mode of magnet attraction, so that open, but because the effect case lid of hinge is difficult for removing.

Summary of the invention

The technical problems to be solved in the utility model is to provide a kind of iron sheet case, and case lid is easily taken away or installed from casing.

For addressing the above problem the technical measures that the utility model takes, be:

A kind of iron sheet case, comprise casing and case lid, and case lid and casing corresponding sides, along having the frame be parallel to each other, are equipped with the magnet concordant with plane on it on some frames; Protruding positioning pin is arranged on some frames, on the contacted frame corresponding with it, have corresponding knock hole.

The iron sheet case of said structure, positioning pin is inserted knock hole back box lid and casing can't parallel, and under the effect of magnet, case lid is pull-in on casing, can easily casing be installed and be connected on casing; In the time of need to pulling down case lid, vertically firmly overcome magnet suction back box lid and can break away from casing, conveniently take off.

As a kind of selection: described positioning pin is arranged on the frame of case lid, is stamping forming bulge-structure, and casing frame correspondence position is provided with the knock hole of respective shapes.

As a kind of selection: described positioning pin is arranged on the frame of casing, is the protrusion in welding, the knock hole that case lid frame correspondence position has respective shapes.

As a kind of selection: described magnet is arranged on the frame of case lid, and on it, plane flushes with the case lid frame.

The specific embodiment

The iron sheet case that case lid the utility model provided below in conjunction with accompanying drawing embodiment is convenient to take off from casing is described further.

In Fig. 1, the iron sheet case comprises casing 1 and case lid 2 two parts, and while normally using, case lid 2 covers on casing 1, and in needs, case lid 2 can whole be taken off from casing 1.

As can be seen from Figure 2, casing 1 and case lid 2 have and are parallel to each other and corresponding frame, have knock hole 3 on the frame of casing 1, on case lid 2 with it correspondence position there is corresponding, the protruding positioning pin 4 in shape and position, when case lid 2 covers on casing 1, positioning pin 4 is inserted in corresponding knock hole 3, can't parallel motion after making case lid 2 with respect to casing 1 location.

Fig. 3 is the enlarged drawing of

positioning pin

4 and 3 one kinds of embodiment of knock hole, and in figure, positioning pin 4 is a cylindrical protrusions pin be welded on case lid 2 frames, with casing 1 frame correspondence position, knock hole corresponding to shape and position is arranged.

Fig. 4 is another embodiment enlarged drawing of positioning pin 4 ' and knock hole 3 ', and in figure, positioning pin 4 ' is stamping forming bulge-structure on case lid 3 frames, on insertion casing 1 frame, in the knock hole 3 ' of correspondence position and shape, realizes location.

Fig. 5 is a kind of embodiment that magnet is installed.In figure, magnet 5 is fixed on the frame of case lid 2, and upper surface is concordant with frame, and when case lid 2 covers on casing 1, magnet 5 is pull-in on the frame of casing 1, makes case lid 2 can not break away from casing.

Simultaneously due to the existence of above-mentioned positioning pin and knock hole, case lid 2 can be not relatively and casing 1 slip, thereby realized fixing of case lid.When needs take off case lid, firmly make it outwards break away from magnet attraction power and get final product.

In the present embodiment, positioning pin and magnet are arranged on case lid, and knock hole is arranged on casing, also can arrange conversely, and knock hole is arranged on case lid, and positioning pin is arranged on casing.For some apparent variations, such as the change of chest outward appearance and structure, the variation of knock hole and positioning pin quantity, shape, position etc., do not change the essence of technical solutions of the utility model, is included in the scope of the utility model protection.
