Abstract

The utility model provides an improved structure of a tape measure, which is essentially characterized in that a slip prevention piece is wrapped on the surface of the shell of the tape measure, utilizing the inner edge of the slip prevention piece to penetrate a plurality of holes on a concave edge of a shell, the inner edge of the shell is filled utilizing the hole, and an inner wrapped edging is formed. Thereby, the shell is wrapped using the slip prevention piece to form an inner and an outer layer, the slip prevention piece is firmly wrapped on the surface of the shell, and a tight and inseparable slip prevention structure is formed to improve the durable character of the tape measure, and prolongs the service life.

Description

The structure-improved of tape measure

The utility model refers to the whole on-slip sheet on a kind of tape measure housing surface especially relevant for a kind of structure-improved of tape measure, adopts the mode of inside and outside coating housing to cement on the housing, thereby can prevent that the on-slip sheet from getting loose, and its sturdy and durable Practical Performance is provided.

General known tape measure, after the main mat plastic cement ejaculation of its two housings is one-body molded, the some carriage bolts of the mat combination that is shaped admittedly again, in order to prevent when gripping tape measure stretching chi band, to produce the phenomenon of skidding, so at chi shell surface rim, utilize the integrated on-slip sheet that is stained with one deck around whole tape measure surface of high temperature, when can preventing to hold tape measure and stretch the chi band, this on-slip sheet produces skidding, after yet the use that the tape measure of commonly using is long-term and the process sun tan by the sun, in the course of time the viscose glue on its chi shell surface can be lost viscosity gradually, thereby produce the perk of on-slip sheet, even the whole situation that comes off takes place, and and nonideal tape measure on-slip sheet; Though the tape measure that has adheres to chi shell surface simultaneously at the on-slip sheet, in on-slip sheet internal layer is provided with the aperture of protruding grain with embedding chi shell housing, but the on-slip sheet is not to be that mode and the chi shell housing that coats closed, and the housing material different with the on-slip sheet formed, so still can produce the situation generation that the insecure generation of on-slip sheet gets loose, so still remain further to be improved necessary.

The utility model people supervises in this, and this journey experience for many years is engaged in accumulation, is study intensively and test improvement repeatedly, nowadays makes a kind of novel tape measure structure finally, can forgo and commonly use the shortcoming of tape measure product, to promote effect.

The purpose of this utility model is to provide a kind of structure-improved of tape measure, utilize the on-slip sheet on tape measure housing surface, the mode of adopting clad type with within the housing, skin envelopes, thereby can prevent that the on-slip sheet on the surface of shell from producing the situation that gets loose, so can strengthen the sturdy and durable Practical Performance of tape measure, prolong its serviceable life.

For achieving the above object, the utility model adopts following design proposal: the rim of housing promptly two housing tops, back, base and to both sides slightly extended spot be provided with recessed edge for the lining of on-slip sheet, on-slip sheet inner edge inwardly runs through the some perforation on the recessed rim of housing, and pour into the housing inner edge by perforation place, form the inside and outside edge strip that coats, and envelope housing with borrowing the inside and outside layer of on-slip sheet, and make the on-slip sheet be overlayed on surface of shell securely, form inseparable Skidproof structure.

In sum, the structure-improved of the utility model tape measure utilizes the mode of the inside and outside coating of on-slip sheet, and housing is closely enveloped, form the structure that the jail can not be divided, under the long-term situation of using the high temperature Exposure to Sunlight, do not have the perk of on-slip sheet or the situation that comes off takes place yet, thereby can guarantee the quality of tape measure, prolong its serviceable life, its function tape measure commonly used absolutely not can be compared, and practical effect is when unquestionable, and the utility model is never made the city know or seen other books and periodicals documents.

The utility model is described in further detail below in conjunction with accompanying drawing

Fig. 1 is the outside drawing of the utility model

Fig. 2 does not install the outside drawing of on-slip sheet for the utility model

Fig. 3 is the part cut-open view of the utility model

Fig. 4 is the structural drawing of the utility model side

Shown in each figure, the utility model is by chi shell housing 1,2, push button 3, chi band 4 and on-slip sheet 5,6 main members such as grade are formed, two left sides wherein, right to being referred to as housing 1,2 are combined into the main framework of tape measure chi shell, can curl for chi band 4 in its inside, the push button 3 of control chi band 4 turnover then is positioned at two housings 1, end before 2,7 on some screws respectively from a housing 2 one ends run through and bolt solid in the double-screw bolt of other end housing 1 and locate, it is characterized in that: two housings 1, the bending downwards of 2 tops is prolonged outstanding shell rim and is respectively equipped with recessed edge 11,21, this recessed edge 11, the on-slip sheet 5 of one deck rubber can be covered on 21,6, on-slip sheet 5,6 are coated on housing 1,2 recessed edge 11, in the time of on 21, this on-slip sheet 5,6 inside rim can run through housing 1 respectively, 2 recessed edge 11, some perforation 22 on 21 limits, and pour into housing 1 by perforation 22, edge within 2, form the edge strip 51 of inner coating, 61 (as shown in Figure 3), so can be with on-slip sheet 5,6 by interior, the outer end envelopes housing 1 respectively, 2, make on-slip sheet 5,6 formation can't be from housing 1, the structure that comes off on 2.

Among linking, two housings 1,2 are concaved with some shrinkage pools 10 respectively on the line, the shrinkage pool 10 of two housings 1,2 is connected to form a rectangular opening, and on-slip sheet 5,6 center line inner edges have some projections 52,62, shown in figure three and figure four, this projection 52,62 can embed respectively in anabolic process in the shrinkage pool 10 of housing 1,2, forms the structure of other end interwoveness.

Claims

1, a kind of structure-improved of tape measure, comprise two housings, push button, members such as chi band and two on-slip sheets, wherein two pairs are referred to as the main framework that shell combination becomes tape measure, can supply chi roll coil of strip song in it, the push button that the control chi is brought into out then is positioned at the housing front end, two housing mat screws and bolt fixed bit, it is characterized in that: the rim of housing i.e. two housing tops, the back, base and to both sides extended spot slightly, being provided with recessed edge can be for the lining of on-slip sheet, on-slip sheet inner edge runs through the some perforation on the recessed rim of housing, and pour into the housing inner edge by perforation place, form the edge strip of inner coating, and borrow in the on-slip sheet, envelope housing outerly, make the on-slip sheet be overlayed on surface of shell securely, form the Skidproof structure of interwoveness.

2, the structure-improved of tape measure according to claim 1, it is characterized in that: line met and is concaved with some shrinkage pools among described two housings were connected, when the on-slip sheet is coated on the housing, its inner rim has some projections and can embed respectively in the shrinkage pool of housing, forms the structure of another interwoveness of on-slip sheet.
