Description
[technical field]
The utility model relates to a kind of casing buckle fixer, and particularly a kind of do not have a fixedly stationary installation of cabinet of screw.
[background technology]
In the prior art, the cabinet of PC mostly fixedly mounts by screw.When producing in batches, this mode that is screwed that makes need be carried out drilling and tapping to the fixed position for the treatment of of cabinet, this treats fixed position with the screw precession then, this mounting means need use the lock screw tool, and is time-consuming, can't satisfy the requirement of large-scale production.Simultaneously, the screw of the omission cabinet that drops also may cause short circuit.In addition, when repairing was safeguarded, the fixed form of this complex steps also usually caused operational trouble.
In view of the foregoing, the fixed form of the existing computer housing of necessary improvement is to overcome
The defective of prior art.
[utility model content]
The purpose of this utility model is to provide a kind of and need not to use the screw just can be with the stationary installation of cabinet stably fastening.
The purpose of this utility model is achieved through the following technical solutions: a kind of casing buckle fixer, it comprises first buckling element and second buckling element that cooperates with cabinet, be provided with along two buckling elements between first buckling element and second buckling element and dock opening and the button hook that direction elasticity fastens, wherein be provided with the elastic recovery sheet that presses on cabinet between second buckling element and the cabinet.
Compared with prior art, the utility model casing buckle fixer adopts fixedly cabinet of two buckling elements that fasten mutually, need not to use screw, easy and simple to handle in complete machine manufacture process and the use, and can save cost, button hook and opening that two buckling elements butt joint direction elasticity fastens can prevent that two buckling elements from getting loose, and the elastic-restoring force of elastic recovery sheet makes second buckling element overturn automatically, thereby realize separating, convenient to operation.

Fig. 2 is the front schematic view of the bayonet unit of the utility model casing buckle fixer.
Fig. 3 is the synoptic diagram that cooperates the elastic recovery element of bayonet unit in the utility model casing buckle fixer.
Fig. 4 is the scheme of installation of the utility model casing buckle fixer.
[embodiment]
See also Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, the utility model chassis cover does not have the screw fixed sturcture and utilizes a bayonet unit 1 and chassis cover 2 mutual buckles to fix to realize no screw.
Bayonet unit 1 comprises first buckling element 10 and second buckling element 11.First buckling element 10 is tabular, and it comprises that a pair of projection 101 is outwards outstanding from two side external surfaces respectively.Second buckling element 11 comprises a tabular roof and a sidewall, and this two side afterbody extends back and forms a pair of long buckle arm 111, and a pair of gudgeon 112 extends in opposite directions from this two side tail surface side direction.This tabular roof hollows out near afterbody one end and forms rectangular aperture 113, and is that the base extends to form semi-cylindrical canyon portion 114 to this tabular stem with this rectangular aperture 113.
First buckling element, 10 lower surfaces buckle by screw and an elasticity that to hold element 12 fixing.This elasticity button is held element 12 and is provided with fixing the buckleing of first buckling element 10 and holds sheet fixed part 121.Button is held sheet fixed part 121 and is extended to form connecting portion 122 forward, forms the button hook 124 that can fasten with the rectangular aperture 113 of second buckling element 2 at the end of connecting portion 122.Hold the middle part self-clinching of the connecting portion 122 of element 12 at the elasticity button and hold sheet fixed part 121 elasticity of flexure arm 123 of the formation of punching press downwards terminal horizontal forward.
Second buckling element, 11 lower surfaces are fixing by a screw and an elastic recovery element 13.This elastic recovery element 13 is provided with and the fixing answer element fixed part 131 of second buckling element 10, replys element fixed part 131 and is provided with a pair of screw (not label) that is used for second buckling element, 11 screw fit.The 131 also downward forward backlash of answer element fixed part are returned to stretch to form and are replied sheet 132.
Chassis cover 2 sides and cabinet 3 sides are equipped with the projection 101 of first slit, 21 corresponding first buckling elements 10, and projection 101 can horizontally slip in first slit 21.Cabinet 3 is provided with the accepting hole (not shown) of second slit, 22 corresponding buckle arms 111 and corresponding gudgeon 112.
During installation, chassis cover 2 cooperatively interacts with cabinet 3, makes first slit 21 and the corresponding respectively coincidence of second slit 22 of both sides.The elasticity button holds element 12 and elastic recovery element 13 is fixing with first, second buckling element 10,11 respectively.The buckle arm 111 of second buckling element 11 inserts second slit 22, and gudgeon 112 cooperates with accepting hole.Elastic recovery element 13 compresses cabinet 3 surfaces, and second buckling element 11 is lifted around gudgeon 112.Projection 101 is snapped in first slit 21 by the elastic deformation of first buckling element 10, and the elasticity of flexure arm 123 that this moment, the elasticity button was held element 12 vertically compresses cabinet 3.Promoting first buckling element 10 moves to second buckling element 11, and push second buckling element 11 to fitting with cabinet 3, make the elasticity button hold the button hook 124 of element 12 and rectangular aperture 113 fastenings of second buckling element 11, bayonet unit 1 is fixed in chassis cover 2 on the cabinet 3.At this moment, elastic arm 123 produces elastic deformation on first buckling element, 10 moving directions, replys sheet 132 and produces elastic deformation on the direction pushing of second buckling element 11.
During dismounting, downwards the button hook 124 of holding element 12 by the dynamic elasticity button breaks away from it in the rectangular aperture 113 of second buckling element 11, this moment is because the elastic-restoring force of elastic arm 123, the elasticity button is held element 12 and is backed down first buckling element 10 automatically backward, and the elastic-restoring force of elastic recovery element 13 makes second buckling element 11 overturn automatically, thereby realize separating, convenient to operation.
The utility model chassis cover does not have the screw fixed sturcture and uses bayonet unit 1 fixing machine box cover 2, not only can improve the efficient of computer production and assembly, reduces the probability of makeing mistakes, and the repairing maintenance of returning computer brings convenience.
