Description
Technical field
The invention belongs to the linkage structure technical field, particularly a kind of linear connection structure technology.
Background technique
Existing linear connection structure technology, can have good application in most cases.But its shortcoming is: the circular cavity that connection strap and base and fastener form coordinates when tight, is not easy to insert cavity; Coordinate not closely, while easily inserting cavity, the connection of base and fastener is firm not, has slightly and rocks.The linear fitting stable connection that Chinese patent ZL200520143483.7 discloses, easily insert cavity, but, when link is longer, the used time of rotation screw thread is longer.
Technological scheme
The object of the present invention is to provide a kind of cooperation tight, stable connection, connection strap easily inserts the linear connection structure of cavity simultaneously.
For achieving the above object, technical solution of the present invention is: a kind of improved linear fitting is comprised of base, fastener and connection strap.Wherein, as shown in Figure 1, its cross section as shown in Figure 2, is a rectangle groove in the middle of it to described base, 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, and a little groove is arranged on semi-circular groove.The another side of rectangle groove is a projection.The another side of projection the same face is fillet, is processed with a plurality of attachment holes on it.As shown in Figure 3, its cross section as shown in Figure 4, is a rectangle groove in the middle of it to described fastener, and the side of rectangle groove is a cuboid, and individual semi-circular groove is arranged on it, and a little groove is arranged on semi-circular groove.The another side of rectangle groove is a projection.On fastener, there is fillet on one side of the face vertical with cuboid, is processed with a plurality of attachment holes on it.Described connection strap, as shown in Fig. 5 and plan view 6, is comprised of spring, screw rod and nut, and spring diameter is slightly smaller than the semi-circular groove diameter, be enclosed within on screw rod, screw rod one end has a screw head, and an end and the screw head of spring are slidably connected, and the other end is fixedly connected with nut.On the nut inner ring, screw thread is arranged, there is N kick outer ring.Screw rod and nut are threaded connection.Shown in Fig. 7 and plan view 8, it is the schematic diagram of spring.Fig. 9 and to look up shown in Figure 10 be the schematic diagram of screw rod and nut.
The connection of base, fastener and connection strap is as shown in Figure 11,12 and 13.But the rectangle groove on the cuboid inserted base on fastener (same, the cuboid on base also inserts the rectangle groove on fastener) wherein, then, two semi-circular groove form a cavity; Then connection strap is inserted to cavity, and kick on nut and the little groove on semi-circular groove are slidably connected; Then the rotary screw head, make the nut compressing spring, and the diameter of spring will increase, and with the cavity that base, first circular trough of fastener form, realizes drive fit.At this moment the semi-circular groove on base has been blocked spring, and simultaneously, spring has also blocked the semi-circular groove on the fastener, makes it to extract by the rectangle groove from base.Therefore, base and fastener have just joined together.And ought be screw head to the opposite direction turn, connection strap just can take out easily from cavity, thus fastener also can be easy to extract from base.
Spring in above scheme also can replace with a columniform hollow rubber post.Simple replacement like this should belong to protection scope of the present invention.
Obvious, above scheme not only can be used in shorter link, also can use in long linear connection structure.
The invention has the beneficial effects as follows: coordinate closely stable connection, the cavity that the easy inserted base of connection strap and fastener form simultaneously.
