Embodiment
Below in conjunction with the drawings and specific embodiments, this case is described in further detail.
This is novel relates to a kind of bending structure straightener, as shown in Figure 1, comprises the first supporting rod 1, the second supporting rod 2, screw rod 3 and connection cord 4.
Described the first supporting rod 1 and the second supporting rod 2 are the strip body of rod, are specifically as follows strip batten or bonding jumper.The mutual moveable hinge of the first free end 21 of the first free end 11 of the first supporting rod 1 and the second supporting rod 2 is connected together.Be concaved with on the first supporting rod 1 on draw-in groove 13, the second supporting rods 2 and be concaved with a draw-in groove 23, the inboard that draw-in groove 13,23 is located at respectively the first supporting rod 1, the second supporting rod 2 is mutually in the face of arranging.
Described screw rod 3 runs through the position near its second free end 12 that is arranged in the first supporting rod 1, and concrete screw rod 3 directly vertically is applied on the first supporting rod 1 or vertically is applied in the screw bolt seat (not shown) arranged on the first supporting rod 1.Screw rod 3 and the first supporting rod 1 and the second supporting rod 2 are in same plane, and screw rod 3 has towards the interior free end of the second supporting rod 2 and the outer free end relative with free end in this.Screw rod 3, with external screw thread, is provided with internal thread in the through hole of the first supporting rod 1, and screw rod 3 can be made free moving rotary on the first supporting rod 1.The interior free end of screw rod 3 adopts connection cord 4 to be connected with the second supporting rod 2.
Lifting the aligning trunk is example, as shown in Figure 1, at first the side in bending trunk L depression bundlees an auxiliary ribband M, by the first supporting rod 1 and the second supporting rod 2, crooked trunk L and auxiliary ribband M are clamped in wherein afterwards, the first supporting rod 1 and the second supporting rod 2 horizontal-extendings, draw-in groove 13,23 aims at respectively bending trunk L and clamping position is made at auxiliary ribband M middle part.The first free end 11 of the first supporting rod 1 and the second supporting rod 2, 21 moveable hinges are connected together, this hinged electricity is as balance pivot, the second free end 12, 22 realize pre-tensioner effect by screw rod 3 and connection cord 4, utilize lever principle in this, screw rod rotation power-saving characteristics, by light outward turning screw rod 3, the second free end 22 that makes the second supporting rod 2 is gradually near the second free end 12 of the first supporting rod 1, the bending part that forces thus bending trunk L straightens and close gradually with auxiliary ribband M gradually, after finally aligning by rope, bending trunk L and auxiliary ribband M bind, make bending trunk L keep the aligning state.Can unload straightener afterwards, for other bending trunks are continued to straightening operation.
In the practical application of this case straightener, adopt the power of 40 jin of left and right can obtain the power of 600 jin of left and right, so can meet the aligning demand of bending trunk or other most of bending structures.The distance of described draw-in groove the 13,23 to first free end 11,21 is the resistance arm of lever, the power arm that the length of the first supporting rod 1 or the second supporting rod 2 is lever.Preferably, can be by reducing resistance arm and/or increasing the power arm mode, to take full advantage of lever construction, do further laborsaving, under the length prerequisite that does not increase the first supporting rod 1 or the second supporting rod 2, reduce resistance arm and increase power arm to realize by the setting position of regulating draw-in groove 13,23, be draw-in groove 13 on the first supporting rod 1 to arrange near the first free end 11 as far as possible, in like manner draw-in groove 23 on the second supporting rod 2 to arrange near the second free end 21 as far as possible.
Preferably, the structure of the groove inwall of draw-in groove 13,23 preferably and the retaining part of bending structure and auxiliary ribband be complementary, such as the clamping part of bending trunk L and auxiliary ribband M all is circular-arc, the internal groove side wall of corresponding draw-in groove 13,23 is the semicircle arc structure.Certainly in order to adapt to the clamping part of different bending structures, the draw-in groove on described the first supporting rod 1 and the second supporting rod 2 can be arranged side by side a plurality of, and the internal groove side wall structure of the plurality of draw-in groove is different.The bending structure is caused to damage when preventing draw-in groove 13 or draw-in groove 23 clamping bending structure (above-described embodiment is the bending trunk), in draw-in groove 13,23 in, each pad is provided with the overcoat of a soft materials formation, and this overcoat is specifically as follows spongy layer.In order to reduce the cushioning effect of overcoat to chucking power, preferably, only in the interior overcoat 14 that arranges of draw-in groove 13, in application, draw-in groove 13 is for clamping the bending structure.
Preferably, the outer free-ended end of described screw rod 3 is provided with a rotating disc 31, by this rotating disc 31, and can be convenient laborsaving in 3 operations of operating personnel's outward turning screw rod.
Preferably, the installation of pre-tensioner state while applying for the ease of straightener, be provided with a connecting ring 24 in the position near its second free end 22 of the second supporting rod 2, is convenient to connection cord 4 with this and carries out disassembled connection on connecting ring 24.
To sum up, this novel straightener terminal with compact integral structure, easy to be laborsaving again in the structure operation of aligning bending, practicality is extremely strong, is suitable for various bending structure straightening operations.
The foregoing is only this novel preferred embodiment, all equalizations of doing with this novel claim scope change and modify, and all should belong to the scope of this novel claim.
