Abstract
The invention discloses a shell for band tape, which comprises: an upper cover (1) with a frame-shape plastic substrate (11) joint with a lower cover (2) both embedded metal core cover (12) into a plastic substrate by integrated injection molding, and a rubber layer (3) on outside of (1) and (2). Wherein, arranging a bulge (11a) on top of (11) and a small hole (12a) on (12) both matched to block (12) on the plastic substrate (11). Compared with prior art, this invention enhances fastness of whole shell with little effect to rubber layer and band tape appearance.
Description
Technical field
The present invention relates to the technical field of tape measure, relate in particular to a kind of housing that is used for tape measure.
Background technology
Tape measure is as a kind of portability survey instrument commonly used, and is all indispensable in construction work such as carpenter, mason, mech.Tape measure generally is made up of housing and the telescopic chi band that is provided with in it, and the housing of tape measure generally is put together by loam cake and lower cover in the market, and loam cake and lower cover mostly are plastic material greatly and are made.Because the characteristics of plastic material, this housing that is used for tape measure, when using, reality skids easily, be difficult for taking, the outside surface that some upper and lower covers therefore occurred is provided with the housing of rubber layer, i.e. the local rubber layer that is fitted with in the upper and lower covers outside of plastic material, finger is when being affectedly bashful tape measure like this, because of the good friction factor of rubber, finger is difficult for skidding on rubber layer, is highly susceptible to holding and gets.But because of plastic material easily breaks, firmness and serviceable life are far away from next good of metal material, and rubber can not directly be fitted on the metal, so the upper and lower covers of metal material just can not directly replace the plastic closure that is fitted with rubber layer.
Summary of the invention
Technical matters to be solved by this invention be provide a kind of upper and lower covers partly to adopt metal material at above-mentioned prior art present situation and guarantee rubber layer can secure fit at the housing that is used for tape measure of upper and lower covers outside surface.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: this is used for the housing of tape measure, include the loam cake and the lower cover of mutual amalgamation and the rubber layer that is arranged on both outside surfaces, it is characterized in that: described loam cake, lower cover all are with the one injection molding way metal core lid to be embedded in plastic basic unit, and are plastic basic unit in the outer surface portions of the described rubber layer of correspondence.
Wherein, the structure that metal core lid combines with plastic basic unit can adopt existing various technology, but for ease of production and processing, when the one injection moulding, the plastic basic unit of described loam cake, lower cover can be made into frame shape, and its top is provided with lug boss, and described metal core lid then has aperture accordingly, the cooperation of aperture makes more firm being fastened on the plastic basic unit of metal core lid on lug boss by described plastic basic unit and the metal core lid;
In the existing tape measure, two lids up and down of housing generally are simply to make both splicings together by screw, like this, just must double-screw bolt be set in one of them of upper and lower covers in its side, wear for screw, and double-screw bolt is processed by injection moulding mostly, double-screw bolt need to combine with plastic basic unit could be firm the enclosure interior that is arranged on, therefore, for ease of the setting of double-screw bolt on plastic basic unit, described metal core lid can have through hole in central authorities, and described plastic basic unit is made into frame shape, and the position of the corresponding described metal core lid center through hole in its top is provided with protuberance, and in order on fixing, the double-screw bolt of lower cover just is set directly under the central protuberance of corresponding plastic basic unit, like this, plastic basic unit also by the cooperation of center through hole on its protuberance and the metal core lid, makes metal core lid be buckled in a side of plastic basic unit.
Compared with prior art, the present invention is combined in structure among the plastic basic unit by upper and lower covers being designed to metal core lid, make plastic basic unit wrap metal core lid, and be still the plastic basic unit part with the binding site of rubber layer, so just guarantee rubber layer still can secure fit outside upper and lower covers the surface, simultaneously, rubber layer has hidden most plastic basic unit, exposed is metal core lid mostly, strengthened the fastness of whole housing undoubtedly greatly, make tape measure no longer be afraid of to fall and be afraid of to split, and do not influence the setting of rubber layer and the overall appearance of tape measure; Moreover rubber layer itself has certain buffer action, so just makes tape measure when accident drops, can not damage housing because of too big impact; Serviceable life of the present invention is longer, and outward appearance is neat and artistic.

Embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As Fig. 1～shown in Figure 5, the housing that this is used for tape measure includes the loam cake 1 and the lower cover 2 of mutual amalgamation and the rubber layer 3 that is arranged on both outside surfaces;
Wherein, described loam cake 1, lower cover 2 all are with the one injection molding way metal core lid 12,22 to be embedded in plastic basic unit 11,21, and are plastic basic unit 11,21 in the outer surface portions of corresponding rubber layer 3;
The plastic basic unit 11 of described loam cake 1 is the frame form, and its top is provided with lug boss 11a, described metal core lid 12 then has aperture 12a accordingly, and the cooperation of aperture 12a is fastened on the plastic basic unit 11 metal core lid 12 on lug boss 11a by plastic basic unit 11 and the metal core lid 12;
And the metal core lid 22 in the described lower cover 2 has through hole 22a in central authorities, and plastic basic unit 21 is the frame form, and the position of the corresponding described metal core lid 22 center through hole 22a in its top is provided with protuberance 21a, and just is set directly under the corresponding plastic basic unit 21 central protuberance 21a in order to the double-screw bolt 21b of fixing described loam cake 1, lower cover 2.
