A spanner with high-strength handle features that its handle has at least one clamp unit at one end for clamping screw or nut, a first axial plane parallel to the clamping plane of clamping unit, and two secondary axial planes which are positioned at both sides of the first plane and intersected with the first plane by a large angle.
Description
Technical field
The present invention relates to a kind of hand-operated tools, particularly relate to a kind of spanner, and the lever of this spanner has higher intensity on the whole, and be easy to grip.
Background technology
Fig. 1 illustrates a kind of structure of known spanner, and the lever 12 of this spanner 10 respectively is provided with a depressed area 14 at end face and bottom surface, and punching press has the numeral of representing size in this depressed area 14 usually, or literal such as brand, material.The setting of this depressed area 14 makes the section concave-convex surface of lever 12, has the effect of strengthening lever 12 structures.Yet, because of limitting on making, the part of lever 12 only is located in this depressed area 14, for the position 15 that is not provided with the depressed area, it then is simple rectangular cross section, its intensity is not as good as having the part of sunk area 14, makes the bulk strength inequality of spanner, and the position 15 that is not provided with the depressed area becomes easy dilapidated part.
Spanner shown in Figure 2 is the spanner 16 of nearer appearance, and the surface of its lever 18 is quite smooth, and nationality is improving texture, but its section is simple fine strip shape, and with regard to the mechanics of materials, its structure is instead not as the intensity of the depressed area 14 of the spanner 10 of Fig. 1.
In addition, the surface smoothing of the lever 12,18 of known spanner 10,16, easy and hand slippage.And the thickness of the side 13,19 of lever 12,18 is less, and the contact area between hand is little, and it is big to pretend the stress that is used for hand, easily causes tingling sensation.Moreover known spanner is metallic luster, seems dull.
This shows that above-mentioned existing spanner still has many defectives, and remains to be improved.

The specific embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to its specific embodiment, structure, feature and the effect thereof that foundation the present invention proposes, describe in detail as after.
At first consult Fig. 3, it is the wrench 20 that a preferred embodiment of the present invention provided, and consists predominantly of: a lever 22, respectively establish a clamping part 24,26 in these lever 22 2 ends, for clamping nut, bolt or analog, clamping part 24 is opening shape person, and clamping part 26 is then poroid for cover.
This lever 22 has one first plane 30, and it probably is parallel to two clamping parts, 24,26 formed clamping planes; Two sides on first plane 30 axially are located at along lever 22 in two second planes 32, and each second plane 32 is wide-angle with first plane 30 and intersects, and for example 90 spend.Each second plane 32 takes shape in the whole length of lever, makes its two end be adjacent to this two clamping part 24,26 trailing edge A respectively.Top, the root edge on each second plane 32 all protrude out first plane 30, as Fig. 4, form height usually.This lever 22 is H shape in the section configuration of any position as shown in Figure 5.
The molding mode on two second planes 32 as shown in Figure 6, two sides of lever 22 each with a roller 35 rollings, nationality is to mold second plane 32 with first plane, 30 2 sides.
With regard to the mechanics of materials, two second planes 32 make the section of lever 22 be H shape (or claiming I shape), and have than high structural strength, simultaneously, because the whole length of lever is equipped with two second planes 32, make the bulk strength homogeneous of lever, there is no the relatively poor destroyed area of intensity and exist, so intensity is better than known spanner.
And two second planes 32 can make lever 22 2 sides have bigger contact area, can improve grip effect, and can improve the contact area with hand, reduce the stress that acts on hand.
Fig. 7 illustrates the section configuration of another preferred embodiment of spanner 40 of the present invention, and wherein: each second plane 46 of lever 42 forms inclined-plane 47 in the inwall place, makes that the thickness on second plane is past interior cumulative, and the tool higher-strength.
Fig. 8 is the another preferred embodiment of spanner 50 of the present invention, and each second plane 54 of its lever 52 forms burr 55 in outer wall.This is as shown in Figure 9, and the surface that goes out the roller 56 on this second plane 54 in order to roll forming is dentation, by this, can form burr 55 at each second plane outer wall, in order to friction to be provided, increases the skidproof effect when gripping.
Figure 10 is a preferred embodiment again of spanner 60 of the present invention, and wherein: this spanner is provided with three open- works 66,66 ' and 66 on first plane 64 of lever 62 ", this three open-work has different width, and different with the A/F of clamping part 68.Respectively but the hexagonal that varies in size of these open-work 66 sockets or four jiaos nut or bolt 68 are seen Figure 11, like this, can improve the usability of lever.
In addition, because lever 62 is between two second planes 70 of first plane 64 and two sides thereof, make the end face and the bottom surface of lever respectively form an accommodation space 72, so, in the enforcement, a non-slippery substance 75 can be located in this each accommodation space 72, as Figure 12 in the mode of filling or spray, this non-slippery substance also is embedded in this each through hole 66, increases the associativity of itself and lever.
This non-slippery substance 75 can be the material of soft or suitable hardness, the comfortableness in the time of can increasing the user and grip lever 62, and non-slippery substance 75 has the on-slip function simultaneously, to prevent the spanner slippage.
In addition, this non-slippery substance can be made into different colours, and tool recognition reaction and vision attract effect, to replace the metallic luster of conventional spanner dullness.
In sum, spanner of the present invention has better structural strength on the whole, is easy to grip, and reduces the stress that acts on hand.And taken off as can be known by each preferred embodiment, spanner of the present invention has anti-skidding effect, has attractability and recognition reaction, can attract client's eye, improves sales rate.
Shown in Figure 13 is graphic, is the force-bearing situation of this spanner,
M: bending moment
Δ: amount of deflection
F: active force
Y: Young number
I: rotary inertia
S: shearing
Mmax＝F×L23
Δ＝(F×L23/3YI)×(1+3L1/2L2)
Strong structural strengths such as spanner provided by the present invention, each position of its lever have are only born bending moment and shear stress when stressed.The section of this lever is H shape (or claiming I shape) structural strength than the known contents height.Even if under identical intensity, the more many known spanners of this spanner are also had a weight reduction and reduce material and the advantage of volume.
The above, it only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs to the scope of technical solution of the present invention to any simple modification, equivalent variations and modification that above embodiment did.
