Abstract

The utility model relates to an improved structure of a number wheel. The outer edge of the top surface of a number wheel body is provided with a plurality of digital slots, the side of a wheel spoke at one side of the body is provided with a reinforced insulating sheet with a proper thickness, and a wheel spoke at the other side is provided with a filling groove. The side wall outside the groove is communicated with the digital slots, and thus, glue materials can be simultaneously filled in each digital slot through filling groove. Digit insulating sheets with proper lengths can be formed among the digit slots. In addition, the other side of the reinforced insulating sheet is provided with a groove, and a plurality of material filling holes are arranged on the reinforced insulating sheet. Thus, both sides of the number wheel have symmetrical visual feelings during the injection molding of the number wheel.

Description

Improved digit wheel structure

The utility model relates to a kind of annex of suitcase

Digit wheel commonly used has digital groove in the digit wheel outer rim mainly by the die cast metal moulding during moulding, fills in color again on this numeral groove after the moulding, is convenient to user's sight and looks number.

The structure of suitcase digit wheel commonly used as shown in Figure 6, the positive and negative wheel abdomen (21) (21 ') of this digit wheel locates respectively to have ten slotted eyes (22), several are arranged is as filling in slotted eye (23) and intercommunication positive and negative slotted eye (22), each slotted eye (22) is equipped with conduit and leads to relative digital groove (24), digit wheel is placed in the mould fill in to taking turns abdomen (21) and conduit until digital groove (24) with injection-moulding plastic.

Suitcase digit wheel commonly used is mainly filled in the plastics of different color and lusters to show numeral by digital groove (24) part.

Said structure still has following shortcoming behind injection-moulding plastic:

1, as shown in Figure 7, because of ten slotted eyes (22) of digit wheel have several be run through fill in slotted eye (23), between the relative slotted eyes in the both sides of not running through (22), form some reinforcement partitions (25), each reinforcement partly causes the separation of digital groove (24), digital outward appearance after producing blank shape on the position of reinforcement partition (25) to make moulding is separated and not attractive in appearance, and its numeral is unintelligible.

2, when by front wheel abdomen (21) material feeding, sizing material fills up extremely half of digital groove (24) of positive wheel abdomen (21) and slotted eye (22) and slotted eye (22) earlier, fill in slotted eye (23) by 4-6 again and flow to reverse side wheel abdomen (21), flow in each reverse side slotted eye (22) and the conduit by reverse side wheel abdomen (21) again, make sizing material can fill up second half digital groove (24) by the conduit of each reverse side slotted eye (22).Factor word groove (24) width is narrow and small, so its cooling rapidly, when the preceding demifacet numeral groove (24) that is positioned at reinforcement partition (25) is filled in material when having cooled off, second half digital groove (24) carries out material feeding by reverse side wheel abdomen (21 '), reverse side slotted eye (22) and conduit again, make the time of digital groove (24) both sides material feeding different, cause and produce defective modes such as seam and bubble between digital groove (24) with temperature.

In view of the defective that the said goods exists, the purpose of this utility model is to provide a kind of new design to make sizing material can once fill in annular groove and digital groove and makes digital groove not have blank gap, not only improves the intensity of digit wheel, and increases the attractive in appearance of digital surface.

The utility model is achieved in that digit wheel body end face outer rim moulding number of digital groove of the present utility model, there is an axis hole in its central authorities, it is characterized in that a side of the wheel abdomen of body forms the reinforcement partition of suitable thickness, the opposite side of wheel abdomen is by the annular groove of filling in of annular die moulding, and this is filled in the annular groove outside and is communicated with digital groove also and makes sizing material fill in each digital groove simultaneously by annular groove by this.

Between the numeral groove the digital partition of suitable length can be arranged, and have some making to fill in the material hole that sizing material is full of digital groove and annular groove on the reinforcement partition.

The utility model compared with the prior art, its advantage is:

1, design of the present utility model can make sizing material once fill in annular groove and digital groove and make digital groove not have blank gap;

2, improved the intensity of digit wheel, the digit wheel both sides have symmetrical visual sense, and have increased the attractive in appearance of digital surface.

Accompanying drawing is described in conjunction with the embodiments:

As shown in Figure 1, 2, the end face outer rim of the utility model digit wheel body 1 has number of digital groove 11, and there is a thinner thickness appropriate location in digital groove 11, highly is lower than the brace 111 of outer edge surface, and there is an axis hole 12 in its central authorities.One side of wheel abdomen 13 has the reinforcement partition 14 of suitable thickness, and the opposite side of wheel abdomen 13 is by the injection moulding annular groove 15 of annular die moulding, and the lateral wall of this annular groove 15 is communicated with digital groove 11.As shown in Figure 3, the liquid sizing material can be filled in the full digital groove 11 of benefit by filling in annular groove 15 when the utility model placed mould to fill in the high-temp liquid sizing material, and digital groove 11 is the sizing material color.Mend hardening by cooling when full owing to fill in annular groove 15 because of sizing material, and to fill in annular groove 15 are solids, so unlikely distortion during rotation digit wheel body 1.

See Fig. 4,13 of the digital grooves of another embodiment of the utility model have the digital partition 16 of suitable length, its reinforcement partition 14 moulding one annular groove 17, at reinforcement partition 14 at several material holes 18 of moulding.Can be full of digital groove 11 and annular groove 17 (as shown in Figure 5) after filling in sizing material, make the utility model both sides have symmetrical visual sense.
