Abstract
Anchor clamps of the present invention have a matrix, the clamping device that is hinged on the sheet alive on the matrix and the matrix and the sheet of living are clamped.Clamping device has a lock dog, and a spin canting is arranged on lock dog, and this spin canting is meshed with flange portion on the sheet of living, utilizes the difference in height of spin canting to realize clamping.The present invention has removed the bolt fastening structure in the conventional brace, has that not to be afraid of rust dead and install and remove characteristics rapidly.
Description
The present invention relates to a kind of anchor clamps of being connected between the steel pipe of builing industry scaffold of being used for, particularly relate to a kind of quickly assembled and disassembled anchor clamps with auto-lock function.
Traditional scaffold clamp mostly adopts bolt to connect, and in actual use, because the duration of a building is all very long, anchor clamps are subjected to wind and weather for a long time, make it to be easy to get rusty.Because the screw thread of bolt is very thin, there is iron mold to bring very big difficulty slightly, even can't dismantles again to dismounting.When running into situation about can't dismantle, the workpeople have to remove it devastatingly, thereby makes it to scrap.And before each the repeated use again with kerosene soak, scrub, tapping and silk rolling again, otherwise just can't use.In addition, when mounting or dismounting, nut must rotate more than two weeks, and it is very inconvenient to install and remove.
The purpose of this invention is to provide and a kind ofly be not afraid of corrosion and install and remove scaffold clamp rapidly.
Solution of the present invention is, the self-lock mechanism of Worm wheel transmission mechanism is applied on the existing anchor clamps that adopt bolted scaffold.Specifically, be the cross section that the lock dog in the clamping device of anchor clamps is likened to worm screw, liken live flange portion on the sheet of anchor clamps a tooth of worm gear to, an end of lock dog is hinged on the matrix of anchor clamps.Like this, when the rotation lock dog, get final product clamp.
The present invention has removed careful screw connection structure, therefore is not afraid of general getting rusty, and owing to adopt Worm wheel transmission mechanism, thereby have the characteristics rapidly of installing and removing.
Below in conjunction with accompanying drawing the present invention is described in detail.
Fig. 1 is a front view of the present invention.
Fig. 2 is the right view of Fig. 1.
Referring to Fig. 1 and Fig. 2, scaffold clamp of the present invention has matrix 1, be hinged on the sheet alive 2 on the matrix 1, on the matrix and the sheet of living, have and scaffold rod member 3 matched circular arcs, free end at the sheet 2 of living has flange portion 4, the bottom 7 of jagged 5, one clamping devices 6 is hinged on the matrix 1 with the universal joint connected mode on flange portion.
Clamping device 6 comprises a bottom 7, neck 8, a lock dog 9 and a manoeuvre portion 10 successively.Wherein bottom 7 can be hemisphere or other structure free to rotate, and the part that cooperates with the bottom on the matrix 1 should adopt corresponding structure.The radial dimension of neck 8 is less than the radial dimension of lock dog 9 and bottom 7.Neck 8 can be inserted in the breach 5.Be provided with on the lock dog 9 one with live body 2 on the spin canting of flange portion engagement, the radian of this spin canting is between 0.5～1.5 π.This spin canting can be spiral camber or straight inclined-plane.On flange portion 4, have a spiral camber that matches with above-mentioned spin canting or straight inclined-plane.Above-mentioned spin canting or revolve curved surface or the difference in height on straight inclined-plane is 2-10mm.
For handiness, the manoeuvre portion among the present invention can be a hexahedron, or has cross-drilled hole 11 on manoeuvre portion, also can be hexahedron (or tetragonal body) and cross-drilled hole structure combining.
For guarantee that clamping device 6 does not withdraw from from breach 5 under clamped condition, the thrust platform (not drawing among the figure) that can prevent that lock dog 9 from skidding off can be set on flange portion 4.The scheme that also can the flange portion 4 by the sheet 2 of will living forms an elevation angle when clamped condition solves the problem that clamping device withdraws from.
Clamping device 6 can be an overall structure, also can be combining structure (as bottom 7 and neck 8 are two bodies, are connected as a single entity after assembling again).
When clamping device 6 is an overall structure, its installation process is, on matrix 1, have the through hole 12 of a band stop portions, with pin 13 it is limited to through hole 12 again after clamping device 6 put into through hole 12, preferably adopts gimbal structure between the bottom 7 of clamping device 6 and the stop portions of matrix 1.
Using method of the present invention is, rod member 3 placed matrix 1 and the sheet 2 of living on circular arc in, again clamping device is inserted in the breach 5 on the flange portion 4, the minimum point that is used in the spin canting on the lock dog 9 is near the inclined-plane minimum point on flange portion 4(or the flange portion 4), use spanner (acting on the hexahedron) or iron staff (inserting in the cross-drilled hole 11) then, rotate manoeuvre portion 10, thereby utilize the degree discrepancy in elevation of said spin canting to realize the clamping of anchor clamps.
Obviously, the present invention is suitable for the anchor clamps of various angles.Though that providing in the accompanying drawing is the embodiment of cross clamp, under the situation that two matrixes are arranged, two matrixes can be with one pivotally connected, and the rotational angle α between two matrixes changes between 0～360 °.Therefore, in not exceeding design scope of the present invention, can make multiple modification.
Claims (9)
1, a kind of scaffold clamp, have matrix and the sheet alive that is hinged on the matrix, on the matrix and the sheet of living, have and the matched circular arc of scaffold rod member, free end at the sheet of living has a flange portion, on flange portion, have breach, the bottom-hinged of one clamping device also can place in the said breach on matrix, it is characterized in that, said clamping device comprises a bottom successively, a neck, a lock dog and a manoeuvre portion, wherein the bottom is connected with the universal joint that is connected to of matrix, the radial dimension of neck is less than the radial dimension of lock dog and bottom, be provided with a spin canting that meshes with the live body flange portion on lock dog, the radian of said spin canting is between 0.5～1.5 π.
