Definitions
- the invention relates to a manual cutting and percussion tool, in particular to an axe or a wrong connection.
- An existing axe or hammer structure commonly used is: It is composed of an axe or hammer head with a mounting hole and a handle assembled by interference fit with the axe or hammer head mounting hole, and there is The adhesive is provided with a horizontal pin on the axe or hammer head in a direction perpendicular to the handle.
- the axe or hammer of this traditional structure, its assembling firmness and service life mainly depend on the dimensional accuracy of the handle and the assembling hole and the bonding effect of the adhesive.
- the object of the present invention is to overcome the above-mentioned shortcomings of the prior art and provide a firmly connected axe or hammer with high pull-out force, high reliability, and long service life.
- the firmly connected axe or hammer of the present invention includes an axe or hammer head with a blind hole for assembly and a handle, wherein the bottom end of the blind hole for mounting the axe or hammer head is inverted tapered, and the blind hole for assembly leaves the bottom end
- the middle and upper parts are cylindrical; an inverse wedge corresponding to the shape of the assembling blind hole is provided in the assembling blind hole, the handle is hollow and tubular, and the front end of the assembling end is located between the assembling blind hole and the inverting wedge. Between the wedges of the wedge.
- a plurality of clamping jaws are arranged on the side wall of the front end of the handle assembly end along the longitudinal axis direction of the handle.
- the clamping jaws are four.
- the maximum outer diameter of the tapered portion of the inverted wedge is larger than the inner diameter of the tubular handle and smaller than the outer diameter of the tubular handle.
- an adhesive is provided between the handle wall and the axe or hammer head, and between the handle inner wall and the inverted wedge.
- the front end portion of the inverted wedge block protrudes from the axe or hammer head by 10-50 mm.
- the front end of the inverted wedge extends 20 mm from the axe or hammer.
- an end of the inverted wedge block near the bottom end of the assembled blind hole of the axe or hammer head has a section of cylinder.
- the bottom end portion of the blind hole of the axe or hammer head assembly is an inverted cone shape, and the middle and upper part of the blind hole from which the blind hole is fitted is cylindrical; and the handle is a hollow circular tube shape.
- a retaining ring is provided on the handle near the axe or hammer head, and a rubber sleeve is sleeved on the outside of the handle.
- the advantages and positive effects of the firmly connected axe or hammer of the present invention are: it includes an axe or hammer head with a blind hole for assembly and a handle assembled with the blind hole for assembly through interference fit; due to the assembly of the axe or hammer
- the bottom end of the blind hole has an inverted cone shape; an inverted wedge block corresponding to the shape of the assembled blind hole is provided in the assembly blind hole; during the assembly of the axe or hammer head and the handle, under the action of the inverted wedge block, Generates a large squeezing force, which greatly improves the pull-out force of the axe or hammer, enhances its reliability, and prolongs its use. Life is more than three times that of existing axe or hammer.
- FIG. 1 is a schematic sectional view showing a first embodiment of a hard-connected axe or hammer according to the present invention
- Fig. 2 is a sectional view taken along A-A in Fig. 1;
- Fig. 3 is a sectional view taken along the line B-B in Fig. 1;
- Fig. 4 is a schematic sectional view showing a second embodiment of a firmly connected axe or hammer according to the present invention.
- FIG. 1 is a schematic cross-sectional structure diagram of a hand axe, which is a first embodiment of a hard-connected axe or hammer according to the present invention, which includes an axe 1 with a blind hole for assembly and a handle 2 assembled with the blind hole for assembly through interference fit.
- the handle 2 is a hollow circular tube, and four clamping jaws 3 are evenly distributed along the longitudinal axis of the handle at the side wall of the assembly end.
- the number of jaws can also be determined as three, six, eight, etc. according to the diameter of the handle and the model of the axe or hammer.
- the bottom end of the assembling blind hole of the axe 1 is an inverted conical shape, and the assembling blind hole is cylindrical from the middle and upper part of the bottom end portion.
- An inverse wedge block 4 corresponding to the shape of the assembling blind hole is provided in the assembling blind hole, that is,
- the inverted wedge 4 is composed of a tapered portion and a bottom cylindrical portion 5 and a front cylindrical portion.
- the maximum outer diameter of the tapered portion and the outer diameter of the bottom cylindrical portion 5 are larger than the inner diameter of the tubular handle 2 and are smaller than
- the outer diameter of the tubular handle 2 is 0.5 mm smaller; the minimum outer diameter of the tapered portion and the outer diameter of the cylindrical portion at the front end are smaller than the inner diameter of the tubular handle 2 by 0.1 to 0.4 mm.
- the assembly end of the tubular handle is plastically deformed by the pressure of the inverted wedge 4 under the impact of the assembly impact.
- the assembly end of the handle 2 can also be divided into clamping jaws. It is cylindrical as a whole.
- the jaw 3 is clamped between the fitting blind hole and the inverted tapered portion of the inverted wedge 4. In this way, when assembling the handle 2 to the axe 1, the assembling impact force causes the outer cone of the inverted wedge 4 to face the tube wall of the handle 2 to produce a large squeezing force.
- the front end of the inverted wedge 4 extends 20 mm from the axe or hammer head, which increases the static load test strength of the present invention, while avoiding stress on the handle 2 near the axe or hammer body due to the assembly with the axe or hammer head Concentrated, effectively preventing the handle from breaking when the axe or hammer is forced to pry. It is possible to extend the axe 10 ⁇ 50mm from the front end of the inverted wedge 4; the specific size can be determined according to the size and model of the axe or hammer.
- the end of the inverted wedge block 4 near the bottom end of the blind hole of the assembly of the axe or hammer head has a section of a cylinder 5 integral with it.
- the role of the cylinder 5 is to facilitate the assembly and ensure the cooperation between the heel surface of the inverted wedge block and the assembly end of the handle 2 length.
- a baffle 7 is provided on the handle 2 near the axe 1.
- a rubber sleeve 6 is set on the outside of the handle 2.
- the handle 2 of the axe or hammer may also be a hollow square tube.
- the bottom end of the blind hole of the axe 1 is chamfered, and the middle and upper part of the blind hole of the axe 1 from the bottom end is a square tube.
- the handle 2 may also be a tube with an oval cross section or an empty tube of other shapes.
- Fig. 4 is a schematic cross-sectional view of a claw hammer, which is the second embodiment of the axe or hammer firmly connected according to the present invention.
- the connection structure between the handle and the claw hammer head is exactly the same as the structure of the front axe and the handle, and will not be described in detail.
- the axe or hammer with a strong connection of the present invention has no horizontal pin holes on the outer surface of the axe or hammer head, which is not only beautiful, but also prevents entry of miscellaneous shields due to the horizontal pin holes, prevents rust on the inner wall of the steel pipe handle, and is beneficial to prolonged use. life. Its assembly is firm, with high tensile and bending strength, safe and reliable use, simplified procedures, small workload, advanced manufacturing technology, And it can be automated to improve work efficiency. It is a hand tool with stable quality and high reliability.
- the reverse wedge-type connection and assembling method of the handle and the axe or hammer head of the present invention is not limited to the axe or hammer, but is also applicable to percussion or other cutting hand tools such as picks.
