The utility model proposes a kind of key spray sheltering fixtures 100, for spraying key 200.

Fig. 1 is please referred to, which includes keypad 21 and several keycaps 22 for being convexly equipped in keypad 21, which hides Spraying jig 100 includes upper cover 1, and upper cover 1 includes mounting plate 11 and several nut caps 12, and the corresponding each keycap 22 of mounting plate 11 offers Key hole 111, each nut cap 12 are covered on key hole 111, and each nut cap 12 is formed with accommodating chamber, and mounting plate 11 is adjacent to key hole 111 are convexly equipped with fastener, and nut cap 12 is equipped with fastener, and mounting plate 11 is detachably connected by the cooperation of fastener and fastener with nut cap 12；

Periphery of the mounting plate 11 backwards to 12 side of nut cap is equipped with bound edge 13, and bound edge 13 and mounting plate 11 are enclosed receiving Slot, when upper cover 1 is covered on key 200, keycap 22 is contained in accommodating chamber, and keypad 21 is contained in holding tank.

In the present embodiment, it produces the key 200 finished and enters spraying process, keycap 22 is correspondingly embedded on mounting plate 11 Key hole 111, the key hole 111 on mounting plate 11 forms the spraying position of keycap 22, nut cap 12 is installed on mounting plate 11, with The part for not needing spraying is blocked, various colors can also independently be sprayed by so that each keycap 22 is combined spraying, and And the artificial process pasting gummed paper and being blocked is eliminated, manpower is saved, reduces cost while improving spraying effect.In addition, Keypad 21 is contained in the holding tank that bound edge 13 and mounting plate 11 are formed, and keycap 22 is contained in the accommodating chamber of nut cap 12, with So that upper cover 1 is firmly covered on key 200, prevent in spraying process, key 200 is moved relative to upper cover 1, to influence Spraying effect.

Wherein, mounting plate 11 and nut cap 12 are realized by fastener and fastener fixes, and structure is simple, easy for removal and installation. It is understood that fastener and fastener can be card convex and card hole；Either protrusion and limiting groove, can be in the week of nut cap 12 Annular protrusion is enclosed in edge projection one, and the side wall of key hole 111 corresponds to annular protrusion and opens up limiting groove, realizes 11 He of mounting plate with this The fixation of nut cap 12.

Specifically, the shape of key hole 111 can be round or quadrangle or other polygons, the freedom of nut cap 12 The shape at end and the shape of keycap 22 match.Nut cap 12 includes occlusion part and the enclosing portion for being disposed around occlusion part periphery, is hidden Stopper and enclosing portion are enclosed accommodating chamber, and key is covered on wherein, it will be understood that, enclosing portion is opened by occlusion part to accommodating chamber Mouth is gradually expanded to tapered, realizes that nut cap 12 is abutted with the interference of 111 side wall of key hole.

Fig. 1 is please referred to, the surface of keycap 22 is convexly equipped with positioning bar 221, and the bottom wall of accommodating chamber is equipped with locating slot 121, keycap 22 when being contained in accommodating chamber, and positioning bar 221, which accommodates, to be simultaneously limited in locating slot 121.

It is understood that the positioning bar 221 on 22 surface of keycap is contained in locating slot when upper cover 1 is covered on key 200 In 121, the random movement of key 200 is prevented, prevents colour contamination phenomenon occur in spraying, to protect the products from pollution.

Referring to figure 2., adjacent to 111 projection of key hole, there are two be oppositely arranged limit plate 112, two limit plates to mounting plate 11 112 offer card hole 1121, and the inner wall of nut cap 12 is set there are two the card convex 122 being oppositely arranged, and nut cap 12 is covered on key hole 111 When, two card convexs 122 are sticked in respectively in card hole 1121.

In the present embodiment, the free end of nut cap 12 is equipped with card convex 122, and card convex 122 can be semicircle or wedge shape, when So, it is also possible to the other shapes such as square or cuboid.Limit plate 112 is abutted with the free end of nut cap 12, to realize nut cap 12 preliminary limit, the card hole 1121 on limit plate 112 further fix nut cap 12 with the card convex 122 in nut cap 12, prevent Nut cap 12 is detached from mounting plate 11, influences the yield rate of the spraying of key 200.In addition, limit plate 112 can also surround key hole 111 Periphery setting, the structural strength of limit plate 112 not only can be enhanced, but also increase the abutting of nut cap 12 Yu limit plate 112 Area keeps overall structure more firm.

In addition, the engaging of nut cap 12 and mounting plate 11 in order to further increase, can be arranged multiple card convexs in nut cap 12 122, multiple card convexs 122 are uniformly distributed along the peripheral wall of nut cap 12, and limit plate 112 is correspondingly provided with to be matched with multiple card convexs 122 Multiple card holes 1121 keep the engaging intensity at each position identical to realize that nut cap 12 engages with the firm of mounting plate 11, increase Add integrally-built stability.

Please continue to refer to Fig. 2, limit plate 112 is formed with guiding surface 1122,122 shape of card convex far from one end of mounting plate 11 At there is mating surface 1221, when card convex 122 engages with card hole 1121, mating surface 1221 is slidably matched along guiding surface 1122.

For the ease of the engaging of nut cap 12 and mounting plate 11, the free end of limit plate 112 is formed with guiding surface 1122, card Convex 122 are equipped with mating surface 1221, and mating surface 1221 is arranged in parallel with guiding surface 1122.When needing to assemble, covered along nut cap 12 The direction of conjunction compresses nut cap 12, and mating surface 1221 and guiding surface 1122 fit, and avoids the dislocation of card convex 122 Yu card hole 1121 The mating surface 1221 of cooperation, nut cap 12 is slided along guiding surface 1122, is caught in card convex 122 just in card hole 1121, is installed Process is simply and readily implemented.

Further, mounting plate 11 is an integral molding structure with limit plate 112.

Specifically, the material of upper cover 1 can be plastics or plastic cement etc., and structural strength is high and facilitates processing, 11 He of mounting plate Limit plate 112 can be an integral molding structure, and certainly, limit plate 112 can also be mounted on mounting plate by detachable connection method On 11.

Referring to figure 3., mounting plate 11 has limiting slot 113 adjacent to the periphery of key hole 111, and nut cap 12 is covered on key When hole 111, the periphery of nut cap 12 is accommodated and is limited in limiting slot 113.

More in preferred embodiment, the periphery of nut cap 12 is limited in the limiting slot 113 of the periphery of key hole 111, lid The free end of cap 12 is located between the two sidewalls of limiting slot 113, limits the movement of nut cap 12.In addition, the two of limiting slot 113 Side wall is equipped with chamfering towards the side of nut cap 12, expands the opening of limiting slot 113, closes convenient for the lid of nut cap 12.

Fig. 1 is please referred to, key spray sheltering fixture 100 further includes bottom plate 3, and mounting plate 11, nut cap 12 and bottom plate 3 enclose appearance The periphery of chamber, bottom plate 3 is equipped with limited step 31, and keypad 21 is convexly equipped with fixture block 211,21 He of keypad towards the side of bottom plate 3 When keycap 22 is contained in cavity, fixture block 211 is limited in limited step 31, and the periphery of limited step 31 is abutted with bound edge 13.

In the present embodiment, bottom plate 3 and upper cover 1 enclose cavity, and key 200 is contained in cavity, with this to key 200 It is positioned, prevents the movement of key 200.Further, fixture block 211 is limited in the limited step 31 of bottom plate 3, on keypad 21 Convex block 33 be limited in limited step 31, prevent keypad 21 from moving relative to bottom plate 3.Furthermore the bound edge 13 of mounting plate 11 It is abutted with the side wall of limited step 31, prevents pigment from dripping and entering in cavity from the periphery of keypad 21, pollute and drop Low yield rate causes the waste of resource.

Preferably, the periphery of limited step 31 is equipped with card slot, and the side wall of bound edge 13 corresponds to card slot and is convexly equipped with retention bead, bottom Plate 3 is detachably connected by the cooperation of retention bead and card slot with upper cover 1.
