Description
Technical field
The invention 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: the circular cavity that connection strap and base and fastener are formed cooperates when tight, is not easy to insert cavity; Cooperate not closely, when inserting cavity easily, being connected of base and fastener is firm inadequately, has slightly and rocks.Cavity is inserted in the linear fitting connection that Chinese patent ZL200520143483.7 discloses firmly, easily, but when link was longer, the time spent of rotation screw thread was longer.
Technological scheme
The object of the present invention is to provide a kind of cooperation tight, connect firmly, connection strap inserts the linear linkage structure of cavity easily simultaneously.
For achieving the above object, technical solution of the present invention is: a kind of improvement of linear fitting, form by base, fastener and connection strap.Wherein, described base as shown in Figure 1, its cross section is a rectangle groove in the middle of it as shown in Figure 2, the side of rectangle groove is a cuboid, and individual semi-circular groove is arranged on it, it is big or small identical with first circular trough of fastener, and a little groove is arranged on the semi-circular groove.The another side of rectangle groove is a projection.Projection is a fillet with the another side of one side, is processed with a plurality of attachment holes on it.Described fastener as shown in Figure 3, its cross section is a rectangle groove in the middle of it as shown in Figure 4, the side of rectangle groove is a cuboid, and individual semi-circular groove is arranged on it, and a little groove is arranged on the semi-circular groove.The another side of rectangle groove is a projection.There is fillet on one side of the face vertical with cuboid on the fastener, is processed with a plurality of attachment holes on it.Described connection strap is made up of spring, screw rod and nut shown in Fig. 5 and plan view 6, and spring diameter is slightly smaller than the semi-circular groove diameter, be enclosed within on the screw rod, screw rod one end has a screw head, and an end and the screw head of spring are slidingly connected, and the other end is connected with fixed by nut.On the nut inner ring screw thread is arranged, there is N kick the outer ring.Screw rod and nut are by being threaded.Be the schematic representation of spring shown in Fig. 7 and the plan view 8.Fig. 9 and to look up shown in Figure 10 be the schematic representation of screw rod and nut.
Being connected shown in Figure 11,12 and 13 of base, fastener and connection strap.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, two semi-circular groove are formed a cavity; Then connection strap is inserted cavity, and kick on the nut and the little groove on the semi-circular groove are slidingly connected; The rotary screw head makes the nut compressing spring then, and the diameter of spring will increase, 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 spring, and simultaneously, spring 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.And ought be screw head to the opposite direction turn, connection strap just can take out from cavity easily, thus fastener also can be easy to extract from base.
Spring in the 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 short link, also can use in long linear linkage structure.
The invention has the beneficial effects as follows: cooperation closely connects firmly, and connection strap inserts the cavity of base and fastener composition easily simultaneously.
