Abstract
The utility model provides a fastening structure of plastic casings, which comprises an upper casing and a lower casing. At least two concave platforms are arranged on the upper casing or the lower casing. Convex reverse buckles corresponding to the concave platforms are arranged on the upper casing or the lower casing. Notches are arranged at one ends of the concave platforms. The width of the notches is larger than that of the convex reverse buckles. When the casings are disassembled, the upper casing and the lower casing are rotated oppositely. When the convex reverse buckles just face the notches, the upper casing and the lower casing can be separated easily, thereby achieving easy assembly and disassembly between the plastic casings, avoiding damage to the plastic casings in disassembly of the plastic casings and prolonging service life.
Description
Technical field
The utility model belongs to the linkage structure field, relates in particular to the linkage structure of plastic casing.
Background technique
In the existing technology, the fastening between plastic casing mainly is a kind of mode of structure that the toughness of utilizing plastic material self, distortion and realizing fastens; At present, what the fastening between plastic casing generally adopted is (seeing figures.1.and.2), on a housing 1, concave station 19 is arranged; Corresponding position has protruding back-off 29 on another housing 2, then to the two housings pressurization, through toughness, the distortion of plastic material self; And realize fastening; This mode of structure assembling is simple, convenient, after the upper and lower casing aligned position, applies certain pressure and can accomplish assembling.
But also there are some drawbacks in said structure: relatively stricter to corresponding respective outer side edges size requirement, especially be not easy dismounting, because the existence of structure protrusions back-off 29; Damage easily its structure during dismounting, like protruding back-off 29 places fracture etc., to safeguard, debugging; Just very inconvenient; The immediate shipment complexion is prone to, and dismounting is difficult, and working life is limited.
The model utility content
The purpose of the utility model is to provide a kind of plastic casing with fastening structure, damages the problem of housing when being intended to solve the plastic casing dismounting after fastening in the existing technology easily.
The utility model is to realize like this; A kind of fastening structure of plastic casing; Comprise upper shell and lower shell body, said upper shell is provided with at least two concave stations, and said lower shell body is provided with the protruding back-off corresponding with said concave station; End in said concave station also is provided with a breach, and said gap width size is greater than the width of said protruding back-off.
Further, be provided with protruding spacing muscle in the said concave station.
Further, said protruding back-off is provided with the restraining groove corresponding with spacing muscle.
Perhaps; The utility model can also be used such realization, and a kind of fastening structure of plastic casing comprises upper shell and lower shell body; Said lower shell body is provided with at least two concave stations; Said upper shell is provided with the protruding back-off corresponding with said concave station, also is provided with a breach in an end of said concave station, and said gap width size is greater than the width of said protruding back-off.
Further, be provided with protruding spacing muscle in the said concave station.
A nearlyer step ground, said protruding back-off is provided with the restraining groove corresponding with spacing muscle.
Use technique scheme; One end of said concave station is established a breach, and said gap width size is greater than protruding back-off width dimensions, during assembling; Because upper shell or lower shell body have a breach; Increased the width dimensions of said concave station, with protruding back-off and concave station roughly relatively after, afterburning pressing can make the lower shell body junction button close; Just can combine upper and lower casing after aligning the position of protruding back-off and concave station needn't be in existing technology fully, solve in the existing technology the strict defective of the corresponding validity in position; During the dismounting housing, rotate upper and lower casing relatively, can easily separate upper and lower casing when rotating to said protruding back-off over against breach; In addition; In the state that fastens, said spacing muscle and said restraining groove are the structure of mutual interlock, prevent that upper and lower casing from rotating, separating because of extraneous vibration; Promptly when making said spacing muscle separate interlocking pattern with said restraining groove, certain rotating force could rotate when receiving; Thereby realized that assembling is easy between plastic casing, dismounting is also easy, avoided when the dismounting plastic casing, causing the damage of plastic casing, prolonged working life.

Embodiment
For the purpose, technological scheme and the advantage that make the utility model is clearer,, the utility model is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Embodiment one:
With reference to Fig. 3 and Fig. 4; The utility model embodiment provides a kind of fastening structure of plastic casing; Comprise upper shell 1 and lower shell body 2, said upper shell 1 is provided with two concave stations 11, and said lower shell body 2 is provided with the protruding back-off 21 corresponding with said concave station 11; End in said concave station 11 also is provided with a breach 13, and said breach 13 width dimensions are greater than the width of said protruding back-off 21.
Further, be provided with protruding spacing muscle 12 in the said concave station 11.
Further, said protruding back-off 21 is provided with the restraining groove 22 corresponding with spacing muscle 12.
Use technique scheme; One end of said concave station 11 is established a breach 13, and said breach 13 width dimensions are greater than protruding back-off 21 width dimensions, during assembling; Because upper shell 1 concave station 11 places have breach 13; Increased the width dimensions of said concave station 11, with protruding back-off 21 and concave station 11 roughly relatively after, afterburning pressing can make the lower shell body junction button close; Just can combine upper and lower casing after aligning the position of protruding back-off 21 and concave station 11 needn't be in existing technology fully, solve in the existing technology the strict defective of the corresponding validity in position; Simultaneously, during the dismounting housing, rotate upper and lower casing relatively; Can easily separate upper and lower casing when rotating to said protruding back-off 21 over against breach 13, in addition, in the state that fastens; Said spacing muscle 12 and said restraining groove 22 are the structure of mutual interlock; Prevent that upper and lower casing from because of extraneous vibration rotates, separates, promptly could rotate when certain rotating force makes said spacing muscle 12 separate interlocking pattern with said restraining groove 22 when receiving, thereby realized that assembling is easy between plastic casing, dismounting is also easy; Avoid when the dismounting plastic casing, causing the damage of plastic casing, prolonged working life.
Embodiment two:
The utility model embodiment provides another embodiment of fastening structure of plastic casing; With the foregoing description one described technological scheme difference do, be provided with three concave stations at said lower shell body, said upper shell is provided with the protruding back-off corresponding with said concave station; The other technologies scheme is identical with the foregoing description one; Thereby realized that assembling is easy between plastic casing, dismounting is also easy, avoided when the dismounting plastic casing, causing the damage of plastic casing, prolonged working life.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
