Description
Technical field
The present invention relates to a kind of dimensional measuring instruments, and in particular to a kind of tape measure with high intensity.
Background technology
Tape measure is common measuring tool in daily life.In various work and life occasion, people can be using arriving tape measure
Measurement, for traditional tape measure using plastics as ruler shell, shape-designing has bigger leeway by plastic process method,
There can be various design styles, but ruler shell firmness is small, intolerant to abrasion；Also have using steel housing, its intensity is big, wear-resisting
Damage, still, shape-designing is relatively difficult, and feel is bad, particularly in winter, so, have scientific and technical personnel to the structure of tape measure not
It is improved disconnectedly.
Through looking into, the Chinese utility model patent of existing Patent No. CN200820083622.5《A kind of tape measure》, including
Have tape measure ruler shell and ruler core and tape in tape measure ruler shell, it is characterised in that the tape measure ruler shell be left ruler housing and
Right ruler housing pairing is formed by connecting, moreover, left ruler housing and right ruler housing are as inserts using stainless steel cap, respectively with a left side
Injection-moulded housing and right injection-moulded housing inlay connection, and stainless steel cap main body is at least made to be to be exposed at injection-moulded housing outer surface, this
Kind tape measure combines plastic ruler shell with the advantage of metal scale shell, more both artistic and practical, but also there are some defects for its design
And deficiency, as not also being that metalwork is contacted directly and compressed between the case sections of left and right, but plastic casing compresses together, causes
Its integral strength is declined, and the compression strength, impact strength and crushing strength for making ruler shell are preferable not enough, especially for body
The larger tape measure of product, stainless steel cap needs are suppressed, and cause thickness thinning, intensity is influenced；Because metal shell exists
Outside causes winter feel bad, and because metalwork variation in moulding is few, the appearance design of whole tape measure is made to be subject to the very day of one's doom
System, so being further improved in structure.
The content of the invention
The technical problems to be solved by the invention be for the above-mentioned state of the art and provide it is a kind of it is rational in infrastructure, there is height
Compression strength, the tape measure convenient for appearance design moulding.
Technical solution is used by the present invention solves above-mentioned technical problem：A kind of high intensity tape measure, the ruler including tape measure
Shell and the tape measure component in ruler shell, tape measure component include ruler core, ruler spring, tape and hook, it is characterised in that：It is described
Ruler shell is involuted by ruler shell bottom and ruler cap, metal insert is equipped in ruler shell bottom and ruler cap, at ruler shell bottom and ruler shell
Cover the inner cavity ring wall surface that is combined to form and be equipped with to increase the supporting member of ruler shell intensity, supporting member be in in the annular of ruler shell
Chamber is corresponding, cyclic structure with opening, and the both sides of supporting member are connected admittedly respectively with ruler shell bottom and ruler cap by connector
Fixed, both sides and the metal insert of supporting member offset to form intensity supporting structure.
As an improvement, the ruler shell bottom and ruler cap are to be molded using engineering plastics through secondary forming process, ruler
Shell bottom metal insert and ruler cap metal insert distinguish die casting on the inner wall of ruler shell bottom and ruler cap by one-pass molding, branch
Axially spaced-apart is convexly equipped with the female connecting pole of several bands on the inner wall of bearing member, and ruler shell bottom and ruler cap are equipped with corresponding company
Counterbore is connect, ruler shell bottom and ruler cap are connected with supporting member by fixation by screw.
As an improvement, the ruler shell bottom metal insert and ruler cap metal insert are equipped with centre bore, ruler shell down payment belongs to embedding
The outer edge of part and ruler cap metal insert offers through hole corresponding with the counterbore at ruler shell bottom and ruler cap or open pore,
Ruler shell bottom metal insert and ruler cap metal insert symmetrically offer hollow-out parts centered on centre bore.
As an improvement, the ruler shell bottom and ruler cap are the ring body with outlet extension position, supporting member is equipped with and ruler
The corresponding opening in outlet of shell bottom and ruler cap, the center of the ring body at ruler shell bottom form the fixing axle of support ruler core, ruler shell
The ring body center of lid forms the shaft end planted for fixing axle.
It improves again, the outer surface of the supporting mass is axially arranged with the annular wall of multiple guiding convex ribs, ruler shell bottom and ruler cap
Corresponding guiding groove is formed on face, supporting member is by being oriented to convex ribs with being oriented to the cooperation of groove and ruler shell bottom and ruler cap phase
Connect positioning.
It improves again, the tape port of export behind the ruler shell bottom and ruler cap pairing is equipped with foot pin, in the top of the port of export
Equipped with the bar shaped sliding slot being packed into for button and locking mechanism, corresponding position is equipped with strip gab on the bearer.
It improves again, the supporting member is metal carrier or high molecular material, fibrous material supporting member.
It is further improved, during the post forming of the ruler shell bottom and ruler cap, wherein an engineering material is ABS+
PC composite materials, secondary engineering material is based on elastomer TPE.
It is further improved, the connecting pole on the supporting member is spaced three, is connected on ruler shell bottom and ruler cap
Counterbore is corresponding three.
Finally, belt fastener is installed on the outside of the ruler cap.
Compared with prior art, the advantage of the invention is that：Ruler shell bottom sets metal insert with ruler cap, and at ruler shell bottom
Supporting member is set between ruler cap so that the metal insert of supporting member and ruler shell bottom and ruler cap is mutually against in tape measure and is formed by force
Supporting structure is spent, the intensity of ruler shell is considerably increased, protects tape measure component that can also worked normally under the influence of by external force；Work as branch
When bearing member is metalwork, complete metal coating room can be formed, is effectively protected to inside and outside；It is and because embedding in metal
The outside of part is provided with plastic casing, can improve and improve the feel in winter and be made convenient for the appearance design of whole tape measure
Type；Supporting member is connected by screw with ruler cap with ruler shell bottom, is positioned by being oriented to cooperation of the convex ribs with being oriented to groove, and assembling is steady
It is fixed reliable.The present invention is rational in infrastructure, can rolling by less than 20 tons trucies, there is high high compressive strength, shock resistance
Intensity and crushing strength.
