Abstract
Disclosed is a part upper cover structure. The part upper cover structure comprises a cover body. The part upper cover structure is characterized in that the cover body comprises a cover plate and a cover cap, and the cover cap is arranged on the periphery of the cover plate and bent downward, wherein the cover cap is composed of more than two folded plates, and lower portion of at least one folded plate is set to be arc shape and bent inward. Projection of each arc shape in the vertical direction is exceeded outward a projection position of a connection portion between the folded plates and the cover cap, and lower portions between the folded plates are detached and disconnected. The part upper cover structure is simple in structure and stable in clamping structure. By means of the arc shapes protruded outward of the cover cap folded plates, when the upper cover is clamped inside a part box body, the folded plates are tightly compressed on a wall of a part box by means of elasticity produced by deformation of the arc shapes, so that the upper cover can be tightly clamped and cannot easily fall off.
Description
Technical field
The utility model designs a kind of part accessory structure, belongs to field of machining.
Background technology
The box part is a kind of common part of field of machining and machinebuilding technology, has integral type case type and dismountable, and dismountable box part is typically provided with loam cake or lower cover, to make things convenient for the dismounting processing of part.For the box part that lid is set, the fastness of lid engaging is relatively important, and especially some small-sized box parts are processed the latch-up structure relative complex, under external force, is easy to the situation generation that block comes off, and can have influence on the safety in production of machinery.
Summary of the invention
Technical purpose of the present utility model is the problem that solves prior art, and a kind of part superstructure of stabilized structure is provided.
The technical solution of the utility model is:
A kind of part superstructure, be provided with lid, it is characterized in that, described lid comprises cover plate and housing, described housing is arranged on the peripheral of cover plate and bending downwards, described housing is made of the flap more than two, wherein the bottom of a slice flap is made as aduncate arc at least, the projection of described arc in the vertical direction outwards exceeds the projected position of the connecting portion of this flap and housing, the bottom is separated and is not connected between flap and the flap, so that the displacement of flap arch section does not exert an influence to other parts.
Further technical scheme comprises:
Described cover plate is rectangle, and the housing of described rectangle cover plate periphery comprises four flaps, and wherein a pair of relative flap bottom is made as aduncate arc, and another vertically arranges and be provided with louvre to relative flap.
The long a pair of flap bottom of described housing arranges curved, shorter a pair of flap louvre is set, and long a pair of flap and cover plate connecting portion is made as chamfering or rounded shapes, with the easily scraping of generation of corner angle that reduces part.
Described cover plate is provided with at least one through hole, when on cover tightly when being fastened in the part casing, can utilize the instruments such as hook to go deep into through hole loam cake is pulled out.
Loam cake is pressed down in the part casing to suitable position, and the arch section that flanging protrudes is subjected to the constraint of part tank wall, to intrinsic displacement, makes housing produce an outside pressure, is pressed on the part tank wall, makes cover body structure more firm.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
In order to illustrate the technical solution of the utility model and technical purpose, below in conjunction with the drawings and the specific embodiments the utility model is done further introduction.
A kind of part superstructure, be provided with lid, described lid comprises cover plate and housing, described housing is arranged on the peripheral of cover plate and bending downwards, described housing is made of the flap more than two, wherein the bottom of a slice flap is made as aduncate arc at least, and the projection of described arc in the vertical direction outwards exceeds the projected position of the connecting portion of this flap and housing, and the bottom is separated and is not connected between flap and the flap.
As shown in Figure 1, the cover plate of loam cake is rectangle, the housing of rectangle cover plate periphery comprises four flaps, wherein long a pair of relative flap bottom is made as aduncate arc 1, shorter another vertically arranges and is provided with louvre 3 to relative flap, long a pair of flap and cover plate connecting portion is made as chamfering 2.
Described cover plate is provided with the through hole (not shown) of at least one.
The summit of the relative arc part of longer flap is dropped at the widest position of housing, its width exceeds the width of part casing, separate because of between arc part and the adjacent flap, when loam cake was installed, the loam cake flanging inserted in the part casing, is subjected to the extruding of part tank wall, the free end of arc part is to intrinsic displacement, because the elastic force effect makes arc part produce outside pressure to tank wall, loam cake is fixed and clamped, difficult drop-off thereby make.
Above demonstration and described groundwork of the present utility model, principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
