Description

Tape measure

Technical field

The utility model relates to a kind of tape measure.

Background technology

In various work and life occasion, people can use tape measure and measure, and traditional tape measure is to adopt plastics as the chi shell, its shape-designing has bigger leeway by the plastic process method, various design styles can be arranged, but chi shell firmness is little, not wear-resistant; Also have and adopt the steel housing, its intensity is big, and is wear-resistant, and still, shape-designing is difficulty relatively, and feel is bad, particularly in winter, so, there are scientific and technical personnel that the structure of tape measure is constantly improved.

As the patent No. is 97210654.5 Chinese patent " overlayer of steel tape ", and the overlayer of this kind steel tape suits to use on the steel tape of big specification especially.Cover on the case surface be fixed on steel tape by one deck resilient material and to constitute.Increase its friction force, be difficult for skidding, easy to use, safe, difficult broken, prolonged serviceable life.And can be full bag of continous way or the discontinuous bag of discontinuity with the overlayer that requires attractive in appearance as required, resilient material can be on the identical or different color and has decorative pattern, the rubber of knurling sticks on the steel tape plastic casing with adhesive, has increased the designs and varieties of steel tape and attractive in appearance.But still there are deficiency in its intensity, wearing quality.

It as the patent No. 200620102524.2 Chinese patent " a kind of housing that is used for tape measure ", include the loam cake and the lower cover of mutual amalgamation and the rubber layer that is arranged on both outside surfaces, loam cake, lower cover all is with the one injection molding way metal core lid to be embedded in plastic basic unit, and the outer surface portions at corresponding rubber layer is a plastic basic unit, the plastic basic unit of loam cake is the frame form, and its top is provided with lug boss, metal core lid then has aperture accordingly, the cooperation of aperture on lug boss by plastic basic unit and the metal core lid, metal core lid is fastened on the plastic basic unit, it makes plastic basic unit wrap metal core lid, and be still the plastic basic unit part with the binding site of rubber layer, guarantee rubber layer secure fit surface outside upper and lower covers, rubber layer has hidden most plastic basic unit simultaneously, strengthen the fastness of whole housing, do not influence the setting of rubber layer and the outward appearance of tape measure.

Summary of the invention

Technical problem to be solved in the utility model is to provide a kind of advantage with plastic ruler shell and metal chi shell to combine, reach tape measure both artistic and practical, easy manufacturing at existing background technology.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of tape measure, it includes tape measure chi shell and the chi core and the chi band that are installed in the tape measure chi shell, it is characterized in that described tape measure chi shell is left chi housing and involutory being formed by connecting of right chi housing, and, left side chi housing and right chi housing are to adopt the stainless steel cap as inserts, inlay with right injection-moulded housing with left injection-moulded housing respectively and be connected, and to make stainless steel cap main body at least be to be exposed at the injection-moulded housing outer surface.

As improvement, described left injection-moulded housing and right injection-moulded housing and injection-moulded housing and stainless steel cap boundary transitional region are coated with plastic layer, in the time of necessary, plastic layer can extend to stainless steel case cover zone, resilient material is covered be fixed on the case surface of tape measure, increases its friction force, be difficult for skidding, easy to use, safe, be difficult for brokenly, and prolonged serviceable life of chi shell, improved chi shell fastness.

Further improve, described left injection-moulded housing and right injection-moulded housing are to have left ring body and the right ring body that exports extending part, left and right ring body and being distributed with between the center separately withstands on the support floor of stainless steel cap the inside, makes left ring body and right ring body center form stationary shaft and the axle head that supports the chi core, makes the plastic ruler shell become support component, prevent the distortion of stainless rule shell, simultaneously, can support the chi core components again, structure is rationally practical, reduce the plastics cost, and reduce the weight of chi shell.

As preferably, described support floor number is 3～4, is equally distributed at circumferencial direction, is convenient to make, and makes the chi shell stressed more even simultaneously.

As improvement, described left injection-moulded housing and right injection-moulded housing and stainless steel cap mold button hole cooperation, that supply the locking mechanism button to install on forward top, so that locking mechanism is gone up in assembling.

Further improve, described left chi housing is to be connected or/and card base assembles with screw with right chi housing, so that left chi housing and the involutory assembling of right chi housing couple together.

As improvement, described left injection-moulded housing and right injection-moulded housing outside surface have and plastic layer the cooperatively interact projection or the groove of build-in, and groove presents finger-hole arc substantially, both enriched moulding, improved again between plastic ruler shell and the plastic layer be connected and fixing, simultaneously, be convenient to hold, increase friction force, be not easy to slip out of the hand and land.

Further improve, described ribs strip has mosaic block, cooperates with stainless steel case lid upper embedded hole, is mounted in mutually together, makes the support floor become connecting piece, being connected and fixed of reinforced plastics chi shell and stainless rule shell.Mosaic block can cover at stainless steel case and be up to when injection mo(u)lding goes out the plastic ruler shell on the support floor, or make in advance.

As preferably, described mosaic block is divided into the mosaic block of horizontal direction and the mosaic block of vertical direction.

Compared with prior art, advantage of the present utility model is: the chi shell uses the stainless steel inserts, has promoted the class of product, gives people's top grade, luxurious sensation; The chi shell uses the stainless steel inserts to make the intensity of chi body higher, more durable; The chi shell makes chi surface hardness higher, more wear-resisting with the stainless steel inserts; Adopt encapsulate to make the feel of chi shell better, and improve being connected between plastic ruler shell and the stainless rule shell; Adopt stainless steel, plastics, plastic cement three's combination, concentrated three's advantage, make things convenient for shape-designing and manufacturing, the reasonable integral structure practicality.
