Abstract
The utility model relates to an improved hinge torque device. The centers of all disk-shaped elastic sheets and pressing sheets are provided with trepan holes in the same shape as the cross-section of a clamp plane of an axial rod. Edges of the pressing sheets toward the disk-shaped elastic sheets are convexly provided with opposite rib cage strips corresponding to which the disk-shaped elastic sheets are dented with buckle grooves. The utility model has the advantages of reduced attrition relaxation, a firm structure with no relaxation, stable torque force quality, quick and convenient assembly, etc.
Description
The utility model relates to a kind of follow-on pivot.
The lid in commonly used lightweight robot calculator, computer, stationery or tool box etc., lid keeps stagnating and is positioned required raise angle and do not produce landing when using, and often installs pivot.Pivot commonly used as depicted in figs. 1 and 2, the stage casing of its central rotating shaft 10 is provided with backstop ring portion 11, the one end extends to stator plate 12, end extends to axostylus axostyle 14 in addition, axostylus axostyle 14 is provided with the screw thread 13 blocking plane 15 relative with both sides, axostylus axostyle 14 places and is sleeved on the fixedly pivot hole 17 of bolster 16, each closing of the both sides in pivot hole 17 has the profiled spacer 19 of waveform arc edge 18, be inserted in location-plate 20 on the axostylus axostyle 14 successively, most dish type shell fragments 21, press fixing piece 22 also screws togather and ends loose nut 23, the center of location-plate 20 is provided with the open-work 24 identical with blocking plane 15 section configurations of axostylus axostyle 14, and its major defect is:
1, after prolonged and repeated use, the waveform arc edge 18 of profiled spacer 19 is because of the less easy abrasion loss of area of loop wire contact, or corrodes relative joint surface and form indenture, and the compressing clip pressure that ends loose nut 23 is reduced, and makes the strength deficiency of stagnating the location.
2, dish type shell fragment 21 is pivot cover mode and is placed on the axostylus axostyle 14, ends loose nut 23 pines and moves turn along with rotating to make equally easily, causes the length that presses the location to strengthen, and pressure reduces, and quickens torsion matter and reduces, and makes the strength of stagnating the location significantly consume mistake.
At above-mentioned defective, the inventor creates the technical solution of the utility model through the long term studies exploitation.
The purpose of this utility model is to provide a kind of follow-on pivot, overcomes the drawback of prior art, reaches that loose, the structure that reduces abrasion is firmly not loosely moved, torsion matter is stable and assemble purpose quickly and easily.
The purpose of this utility model is achieved in that a kind of follow-on pivot, the stage casing that is included in central rotating shaft is provided with baffle ring, the one end extends to the stator plate, the other end extends to axostylus axostyle, axostylus axostyle is provided with thread segment and two relative clip planes, axostylus axostyle is inserted in the pivot hole of the fixing end ring plate of bolster, the end ring plate both sides of axostylus axostyle respectively are nested with revolves pad and most dish type shell fragment, press fixing piece, spiral shell ends loose nut admittedly on the terminal thread segment, it is characterized in that: the identical trepanning of section configuration with the clip plane of axostylus axostyle is offered at the center of each dish type shell fragment and press fixing piece, the rim of press fixing piece is convexly equipped with the rib frame bar that is oppositely arranged towards the dish type shell fragment, to being arranged with catching groove by each dish type shell fragment of rib frame bar.
The circle perforation pivot that revolves pad of these end ring plate both sides is placed on the axostylus axostyle, all is concaved with the oil groove trace on its both relative radial facing; This revolves on the radial facing of pad with respect to baffle ring and dish type shell fragment, also can be arranged with the oil groove trace.
Major advantage of the present utility model is:
1, because press fixing piece 41 and each dish type elasticity 40 are provided with relative trepanning 43 and are sticked on the axostylus axostyle 34, makes and end 42 groups of fixing structures of loose nut and more firmly and not can move by pine.
2, press fixing piece 41 rims protrude out relative rib frame bar 44 and corresponding catching groove 45 clamping frames, make a cutting ferrule contraposition of assembling, have and assemble advantage quickly and easily.
3, remove the location-plate that disappears, reduce the number of length.Revolve pad and end ring plate 37 with oil groove trace 47 are face and fit, and cooperate the lubricated of grease, and it is loose to have reduced abrasion loss, and stable torsion matter is provided, and make that structure is firmly not loose moves.
The utility model is further specified as follows below in conjunction with drawings and Examples:
Fig. 1 is the decomposing state synoptic diagram of common structure.
Fig. 2 is the combination longitudinal profile synoptic diagram of common structure.
Fig. 3 is the assembled state synoptic diagram of common structure.
Fig. 4 is a decomposing state synoptic diagram of the present utility model.
Fig. 5 is an assembled state synoptic diagram of the present utility model.
Fig. 6 is a combination longitudinal profile synoptic diagram of the present utility model.
Consult Fig. 4 one Fig. 6, the stage casing of central rotating shaft 30 of the present utility model is provided with baffle ring 31, the one end extends to stator plate 32, the other end extends to axostylus axostyle 34, axostylus axostyle 34 is provided with thread segment 33 and two relative clip planes 35, axostylus axostyle 34 is inserted in the pivot hole 38 of the fixing end ring plate 37 of bolster 36, end ring plate 37 both sides of axostylus axostyle 34 respectively are nested with revolves pad 39 and most dish type shell fragment 40, press fixing piece 41, spiral shell ends loose nut 42 admittedly on the terminal thread segment 33, the identical trepanning 43 of section configuration with the clip plane 35 of axostylus axostyle 34 is offered at each dish type shell fragment 40 and the center of press fixing piece 41, the rim of press fixing piece 41 is convexly equipped with the rib frame bar 44 that is oppositely arranged towards dish type shell fragment 40, and respective ribs frame bar 44 each dish type shell fragment 40 are arranged with catching groove 45.Circle perforation 46 pivots that revolve pad 39 of end ring plate 37 both sides are placed on the axostylus axostyle 34, all are concaved with oil groove trace 47 on its both relative radial facing.Have the abrasion of minimizing, the effect of stablizing torsion matter.Certainly revolve on the radial facing of pad 39 with respect to baffle ring 31 and dish type shell fragment 40, also can be arranged with oil groove trace 47.
The utlity model has reduce that abrasion are loose, structure is firmly not loosely moved, torsion matter is stable and assemble the advantages such as quick and convenient.
