In description of the present utility model, it will be appreciated that, term " " center ", " longitudinally ", " laterally ", " front ", " afterwards ", " left side ", " right side ", " vertically ", " level ", " top ", " end ", " interior ", orientation or the position relationship of instructions such as " outward " are based on orientation shown in the drawings or position relationship, only the utility model and simplified characterization for convenience of description, instead of device or the element of instruction or hint indication must have specific orientation, with specific orientation structure and operation, therefore can not be interpreted as the restriction to the utility model protection domain.
As shown in Fig. 1～6, pin removal provided by the utility model comprises bolt 1, pad 2, contiguous block 3, leading screw 4, support 5 and handwheel 6, and wherein, bolt 1 comprises head 11 and screw rod 12.The upper surface of contiguous block 3 is fixedly connected with one end of leading screw 4, and lower surface offers up big and down small stepped hole 31 from bottom to top, the lucky bearing pad 2 of step of its formation.Pad 2 has the through hole of the screw rod 12 that penetrates bolt 1, and the head 11 of bolt 1 is positioned on pad 2.Support 5 comprises at least two supporting legs 51 and the first center ring 52, and supporting leg 51 is connected to the side of contiguous block 3, and its upper end is connected to each other by the first center ring 52, and lower end is used for being supported on object A.Need explanation, shown in figure is symmetrically arranged two supporting legs 51, is only a kind of example in figure, and support 5 can also comprise three or above supporting leg.The first center ring 52 has the internal thread with leading screw 4 threaded engagement.Handwheel 6 comprises handle 61 and the second center ring 62, and handle 61 is fixedly connected with the second center ring 62, and the second center ring 62 is positioned at the first center ring 52 tops, and has and the internal thread of leading screw 4 threaded engagement.
In the time that this pin removal is used to extract pin, the screw rod 12 of bolt 1 is fastened as a whole bolt 1 and pin for penetrating pad 2 and being screwed into pin; Pad is for being stuck in the head of bolt 1 11 in the stepped hole 31 of contiguous block 3; Support 5 is for being enclosed within leading screw 4, and the groove interlock of supporting leg 51 and contiguous block 3 is also supported on object; Handwheel 6, for being enclosed within the position on leading screw 4 upper bracket 5 tops, is threaded with leading screw 4 by the helicitic texture of the second center ring 62, by the rotation of handwheel 6, leading screw 4 is moved up, and produces the power for extracting pin.The utility model adopts and utilizes hand wheel rotating to produce moment of torsion, extracts gradually pin, rapid operation, and also the screw thread of bolt is without any damage.
In above-described embodiment, as shown in Figures 2 and 3, contiguous block 3 can be rectangle, rectangular contiguous block can and support 5 between can not relatively rotate.The two relative side that contiguous block 3 is connected with supporting leg 51 all offers groove 32, and groove 32 penetrates into upper surface from the lower surface of contiguous block 3 always.The sidewall of the size of groove 32 and supporting leg 51 is suitable, thereby groove 32 can be connected comparatively securely at the sidewall of supporting leg 51.Need explanation, Fig. 2 and 3 is only a kind of example, and the side of contiguous block 3 can also have three or above groove, as long as can match with the quantity of supporting leg 51.
In above-described embodiment, as shown in Figures 1 to 3, stepped hole 31 connects at the other two relative side of contiguous block 3, and when use, pad 2 can be put into stepped hole 31 freely from a side of contiguous block 3.Because step dimension and the pad 2 of stepped hole 31 match, that is to say, pad 2 snaps in the upper hole of stepped hole 31 just, for bolt 1.
Fig. 4 illustrates the schematic diagram as the pad 2 of the conjunction of the pad in multiple apertures.As shown in Figure 4, in order to adapt to the pin of various sizes, need to use and change the bolt 1 that uses different model size, correspondingly, the aperture of the through hole on the pad 2 of connecting bolt 1 use also needs different, and pad 2 is provided with the through hole 21 of several different pore sizes.The pad 2 of porous can strengthen versatility of the present utility model.Pad 2 can be rectangle, can be also the irregularly shaped of other, as long as can ensure that pad 2 snaps in the upper hole of stepped hole 31 just.
Pin removal provided by the utility model also comprises the backing plate 511, spring 7 and/or the thrust bearing 8 that in Fig. 1, also illustrate.
Backing plate 511 is positioned at the bottom of supporting leg 51, and backing plate 511 can adopt the material such as plastics or silica gel to make, when the contacting of support 5 and part A, on the one hand can increasing friction force, and increase the stability of supporting leg 51, protect on the other hand part A surface to avoid wearing and tearing.
Spring 7 is set on leading screw 4, between contiguous block 3 and support 5, utilizes pin removal that the utility model provides to extract the laggard horizontal reset of pin.
Thrust bearing 8 is set on leading screw 4, between handwheel 6 and support 5, for reducing the friction between the second center ring 62 and the support 5 of handwheel 6, has protected the utility model.
Need explanation, pin removal also can not comprise backing plate 511, spring 7 and/or thrust bearing 8.For example, even without backing plate 511, support 5 also still can be realized the effect of support.
As shown in Figure 1, use the utility model when connecting the pin C of object A and object B, choose suitable bolt 1, penetrate in the through hole 21 of correspondingly-sized of pad 2, bolt 1 is screwed into pin C is fastened as a whole it, lift pad 2 and be inserted in contiguous block 3, make the center of bolt 1 and leading screw 4 on an axis, spring 7, support 5 are set on leading screw 4 in order with thrust bearing 8, make the backing plate 511 and part A Surface Contact of support 5 bottoms, be screwed into handwheel 6, and handwheel 6 is continuously applied to moment of torsion, pin C extracts the most at last.
Finally should be noted that: above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit; Although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the field are to be understood that: still can modify or part technical characterictic is equal to replacement detailed description of the invention of the present utility model; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope of the utility model request protection.
