Description
Technical field
The utility model belongs to the linkage structure technical field, particularly a kind of linear linkage structure technology.
Background technique
Existing linear linkage structure technology can have good application under most of situation.But its shortcoming is: one, only suitable the employing with aluminum alloy, plastics of the complicated shape of base and fastener is the extrusion process production of material.Linear fitting as Chinese patent ZL200520143483.7 disclosure.And can not adopt with the iron and steel is the stamping process production of material.Two, when base and fastener are longer, used time of rotary screw is longer.
The model utility content
The purpose of this utility model is to provide a kind of cooperation tight, connects firmly, and adopting with the metal is the stamping process production of material, simultaneously the used short linear linkage structure of time of rotary screw.
For achieving the above object, technical solution of the present utility model is: a kind of improvement of linear fitting, as shown in Figures 1 and 2, form by base, fastener and screw rod.Wherein, described base is a fillet in the middle of it as shown in Figure 3, is processed with a plurality of attachment holes on it.The fillet two ends respectively are vertical end faces, and as shown in Figure 4, the diameter of the semi-circular groove of an end face is bigger than another.In the middle of the end face is a rectangle groove, and the side of rectangle groove is a cuboid, and individual semi-circular groove is arranged on it, and its size is identical with first circular trough of fastener.The another side of rectangle groove is a projection.The end face next door connects more than one pressing block, and (effect that connects pressing block is the difficulty of processing that reduces punching press.So, also can not connect pressing block stressed less or in acceptable difficulty of processing scope), its size, shape and end face are identical, fixedly connected with end face by welding, pin etc.End face and pressing block combination back machining screw on semi-circular groove, and identical with the screw thread of screw rod respective step.
Described fastener is a fillet in the middle of it as shown in Figure 5, is processed with a plurality of attachment holes on it.The fillet two ends respectively are vertical end faces, and as shown in Figure 6, the diameter of the semi-circular groove of an end face is bigger than another.In the middle of the end face is a rectangle groove, and the side of rectangle groove is a cuboid, and individual semi-circular groove is arranged on it, and its size is identical with first circular trough of base.The another side of rectangle groove is a projection.The end face next door connects more than one pressing block, and its size, shape and end face are identical, fixedly connected with end face by welding, pin etc.End face and pressing block combination back machining screw on semi-circular groove, and identical with the screw thread of screw rod respective step.
Described screw rod such as Fig. 7 and analyse and observe shown in Figure 8ly, screw rod one end has a disk, is used for supporting object and as knob.Below the disk the bigger threaded big step of diameter (obviously, have on the step of assurance and base or fastener connection part screw thread just passable).Can coincide with the screw thread of the bigger semi-circular groove of diameter on base and the fastener.It below the big step the threaded middle step of the little one-level of diameter.Can coincide with the screw thread of the less semi-circular groove of diameter on base and the fastener.Below the middle step is the littler threaded small stair of diameter.Can coincide with the screw thread of lower margin etc.
Being connected as shown in Figures 1 and 2 of base, fastener and screw rod.Wherein the cuboid on the fastener can insert the rectangle groove (same, the cuboid on the base also inserts the rectangle groove on the fastener) on the base, and then, four semi-circular groove are formed small one and large one two cavitys; Then the small stair of screw rod is inserted from big cavity direction, make through respectively big cavity of big step and middle step and areola; Rotating disk makes the screw thread of big step and middle step identical with the screw thread of big cavity and areola respectively then.At this moment the semi-circular groove on the base has been blocked screw rod, and simultaneously, screw rod has also blocked the semi-circular groove on the fastener, makes it and can not extract from the rectangle groove on the base.Therefore, base and fastener have just joined together.
Shown in Figure 9 is the schematic representation that base, fastener, screw rod and lower margin are connected.Wherein, the small stair of screw rod is connected with lower margin.
Above scheme changes a little also and can be made up of base, fastener, connection strap as Figure 10 and shown in Figure 11, and wherein, described base is a fillet in the middle of it as shown in figure 12, is processed with a plurality of attachment holes on it.The fillet two ends respectively are vertical end faces, as shown in figure 13, are rectangle grooves in the middle of the end face, and the side of rectangle groove is a cuboid, and individual semi-circular groove is arranged on it, and its size is identical with first circular trough of fastener.A little groove is arranged on the semi-circular groove.The another side of rectangle groove is a projection.The end face next door connects N pressing block, and its size, shape and end face are identical, fixedly connected with end face by welding, pin etc.
Described fastener is a fillet in the middle of it as shown in figure 14, is processed with a plurality of attachment holes on it.The fillet two ends respectively are vertical end faces, as shown in figure 15, are rectangle grooves in the middle of the end face, and the side of rectangle groove is a cuboid, and individual semi-circular groove is arranged on it, and its size is identical with first circular trough of base.A little groove is arranged on the semi-circular groove.The another side of rectangle groove is a projection.The end face next door connects N pressing block, and its size, shape and end face are identical, fixedly connected with end face by welding, pin etc.
Described connection strap is made up of inclined-plane sleeve pipe, screw rod and nut as analysing and observe shown in Figure 16 and 17, and as shown in figure 18, the inclined-plane sleeve pipe is made up of inner sleeve and outer sleeve, and internal and external casing connects by tapered slope.The inner sleeve outside is a tapered slope, and the centre is a pipe, and diameter is a bit larger tham screw rod, can be enclosed within on the screw rod.Outer sleeve is formed (perhaps semicircle two-part connect together slightly, and can rupture in the joint when extruding) by two semi-circular portions, and cylindrical is the cylndrical surface, and diameter is slightly smaller than the semi-circular groove diameter, and the centre is a tapered slope, is connected with the tapered slope of inner sleeve.As shown in figure 19, screw rod one end and nut are by being threaded, and the other end has a disk, and there is a step middle and upper part.There is N kick the nut outer ring.Between the step of screw rod and nut, be connected the inclined-plane sleeve pipe.
Being connected of base, fastener and connection strap as 10 and shown in Figure 11.Wherein can to insert rectangle groove on the base (same for the cuboid on the fastener, cuboid on the base also inserts the rectangle groove on the fastener), then, four semi-circular groove are formed two cavitys: then connection strap is inserted cavity, kick on the nut and the little groove on the semi-circular groove are slidingly connected, and make the step of screw rod prop up the outer sleeve of inclined-plane sleeve pipe; Rotating disk makes nut extruding inner sleeve then, and the tapered slope between the internal and external casing will be pushed mutually, thereby the cylindrical of outer sleeve is expanded, and realizes drive fit with the cavity that base, first circular trough of fastener are formed.At this moment the semi-circular groove on the base has been blocked the inclined-plane sleeve pipe, and simultaneously, the inclined-plane sleeve pipe has also blocked the semi-circular groove on the fastener, makes it and can not extract from the rectangle groove on the base.Therefore, base and fastener have just joined together.
After adopting above scheme, the beneficial effects of the utility model are: cooperate closely, connect firmly, adopting with the metal is the stamping process production of material, and used time of rotary screw is shorter simultaneously.
