Embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
The utility model embodiment discloses a kind of angle-inserting type and has put pike pole, to realize that solving the existing pike pole support outer tube when placing weight of putting produces the problem of slip easily.
As shown in Figure 3, the angle-inserting type that the utility model embodiment provides is put pike pole and is comprised foot 1, intermediate support part 2 and upper bracket part 3, wherein, comprise the intermediate support joint 21 that is provided with support installing hole 211 and handwheel installing hole 212 in the intermediate support part 2, support outer tube 31 in the upper bracket part 3 is arranged in the support installing hole 211, and the handwheel 22 of limiting bracket outer tube 31 is installed in the handwheel installing hole 212.
As shown in Figure 4, compare with the existing pike pole of putting, angle-inserting type provided by the utility model is put in the pike pole, and support installing hole axis and horizontal plane angle α are less than 90 degree.Complete in assembling, and after putting pike pole and applying weight, the directed force F that weight acts on the support outer tube can be broken down into along the first directed force F of support outer tube axis direction
1With the second directed force F perpendicular to support outer tube axis
2The first directed force F
1=F * cos α, because angle α is less than 90 degree, so cos α is all the time less than 1, i.e. the first directed force F
1Less than directed force F, also just less than with the equal-sized weight gravity of directed force F G.Therefore, under square one, as weight gravity G=F〉F
fThe time, the existing pike pole support outer tube of putting has begun down sliding, and angle-inserting type provided by the utility model puts pike pole because F
1=cos α F=cos α G＜F
f, the support outer tube can not slide.
By the above, angle-inserting type provided by the utility model is put the bearing capacity that pike pole has improved product, solves the existing pike pole support outer tube when placing weight of putting and produces easily the problem of slip.
On the basis of above-described embodiment, further, angle α is greater than 45 degree.By geometric knowledge as can be known, when angle α equals 45 when spending, its cosine value equals its sine value, in conjunction with Fig. 5 as can be known, i.e. and the first directed force F
1With the second directed force F
2Equal and opposite in direction, when angle α continues to reduce, the second directed force F
2Can increase, because the second directed force F
2Perpendicular direction in the axis of support outer tube 31, the second directed force F
2Increase can strengthen the suffered moment of flexure of support outer tube 31, when the bending resistance of support outer tube 31 was not enough, support outer tube 31 can distortion or is fractureed, and therefore, is necessary to limit angle α greater than 45 degree.
