The specific embodiment
For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer; To combine the accompanying drawing in the embodiment of the invention below; Technical scheme in the embodiment of the invention is carried out clear, intactly description; Obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
Referring to figs. 1 through shown in Figure 4, present embodiment door machine hinge is installed and to be aligned instrument fast, comprises free bearing 1, lifting screw 2, up-down cone 3, support member 4 and with lifting screw 2 threaded engagement and be positioned at the hinge wheel 5 of free bearing 1 top; Free bearing 1 is that two halves are split type, comprises two sub-free bearing 1-1 that are oppositely arranged, and it vertically is provided with gathering sill 1-2 the inwall upper edge of free bearing 1-1, when two sub-free bearing 1-1 to fashionable, free bearing 1 is whole cylindrical; In the space of up-down cone 3 between two sub-free bearing 1-1, and be installed on the bottom of lifting screw 2, can adopt the mode of welding to set firmly, the outer wall of up-down cone 3 be provided with sub-free bearing 1-1 inwall on the guide rail 3-1 that matches of gathering sill 1-2; Support member 4 is between hinge wheel 5 and free bearing 1, and with bloster hinge wheel 5 and lifting screw 2, and support member 4 is provided with and is used for the through hole that lifting screw 2 passes.
Adopt present embodiment door machine hinge the hinge connecting hole of hinge connecting hole and rotating disk 7 that the instrument of aligning fast carries out arm support of portal hoist 6 to be installed to correct time, with reference to shown in Figure 1, rotation hinge earlier takes turns 5; Under the threaded engagement effect of hinge wheel 5 and lifting screw 2, make lifting screw 2 drive up-down cones 3 and move downward to the lowermost end of free bearing 1, this moment, the diameter d of free bearing 1 bottom was a smaller value; Successively insert hinge connecting hole and the hinge connecting hole of arm support of portal hoist 6 capstan 7 on this instrument that aligns this moment, and after the insertion, the rotation hinge takes turns 5; Make up-down cone 3 under the drive of lifting screw 2,, promote two sub-free bearing 1-1 and move away to both sides along moving on the gathering sill 1-2 on the sub-free bearing 1-1; It is consistent with the diameter of the hinge connecting hole of arm support of portal hoist 6 that the diameter d of free bearing 1 bottom is extended to gradually; With reference to shown in Figure 5, thereby arm support of portal hoist 6 firmly is fixed on the rotating disk 7, the hinge connecting hole of arm support of portal hoist 6 and the hinge connecting hole of rotating disk 7 align fully at this moment; On the hinge connecting hole of bottom end side preparatory plug-in mounting to arm support of portal hoist 6 of free bearing 1 with hinge; The wheel of rotation hinge then 5 reduces the diameter of free bearing 1, present embodiment door machine hinge is installed the instrument that aligns fast unload along extracting out away from the direction of arm support of portal hoist 6, and the hinge plug-in mounting is complete; Can accomplish arm support of portal hoist 6 and install, with reference to shown in Figure 6.
For the motion that makes up-down cone in the present embodiment 3 and sub-free bearing 1-1 steady; The wall thickness of sub-free bearing 1-1 is reduced by top to bottom gradually; Thereby its inwall is taken the form of inclined plane; The conical surface of this inclined-plane and up-down cone 3 is suitable, and the conical surface of the cone of promptly going up and down 3 can be fitted with the inwall of sub-free bearing 1-1 fully, has guaranteed robust motion.
Owing to except that lifting screw 2 and up-down cone 3 are fixed as one, be the building block system assembled relation between other each parts, then the installation of present embodiment door machine hinge fast the instrument of aligning be demountable structure, be convenient to deposit.Certainly, also can keep its package assembly, so that hand-held carrying; Top at sub-free bearing 1-1 also is provided with the wing lug 1-3 that turns up; Turn up wing lug 1-3 can with sub-this body by integral forming of free bearing 1-1, then in when carrying, adopt both hands hand-held respectively hold the wing lug 1-3 that turns up can whole carrying; Simultaneously, the wing lug 1-3 that turns up also can play position-limiting action, and promptly after present embodiment door machine hinge was installed the hinge connecting hole that aligns fast on the instrument insertion capstan 7, the wing lug 1-3 that turns up was connected on place, the aperture capstan wall at hinge by backstop, plays position-limiting action.
For alleviating present embodiment door machine hinge as much as possible the weight of the instrument that aligns fast is installed, is convenient to hand carrying and manipulate, sub-free bearing 1-1 is provided with loss of weight fabrication hole 1-4, and up-down cone 3 is provided with loss of weight fabrication hole 3-2.
The above only is preferred embodiment of the present invention, is not to be the restriction of the present invention being made other form, and any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.But everyly do not break away from technical scheme content of the present invention, to any simple modification, equivalent variations and remodeling that above embodiment did, still belong to the protection domain of technical scheme of the present invention according to technical spirit of the present invention.
