Detailed description of the invention

Embodiment one

As shown in Figure 1 and Figure 2, connector of the present utility model includes insertion rod 10, sleeve pipe 20, intermediate plate 30 and spring 40.

Sleeve pipe 20 includes that mouthful end 21, bottom 24, small end are positioned at inner conical surface 22 and of 20 mouthfuls of ends 21 of sleeve pipe The inner cylinder face 23 being positioned at sleeve pipe 20 bottom 24, this inner cylinder face 23 and bullet it is connected with this inner conical surface 22 The external diameter of spring 40 is suitable.

Inner cylinder face 23 is set, spring 40 can be made less with sleeve pipe 20 fit clearance.Implement at other In example, sleeve pipe 20 is not provided with inner cylinder face 23, does not affect the realization of the present utility model purpose.

Insertion rod 20 uses cylindric.

Intermediate plate 30 includes outside and the male cone (strobilus masculinus) of inner conical surface 22 adaptation of sleeve pipe 20, inner side and insertion rod 10 Adaptive cylindrical hole.Intermediate plate 30 is divided at least more than two panels along its length, to ensure intermediate plate 30 When being pushed by spring 40, under the position-limiting action of the inner conical surface 22 of sleeve pipe 20, the clamping of its cylindrical hole is inserted Bar 20.As shown in Figure 4, in the present embodiment, intermediate plate 30 is divided into three monolithic intermediate plates 32, at it In his embodiment, as required, intermediate plate 30 can use two panels, four, five or more multi-sheet structure.

As it is shown in figure 1, in the assembled condition, intermediate plate 30 is positioned at sleeve pipe 20, and spring 40 is positioned at sleeve pipe The bottom of 20 also pushes this intermediate plate 30 and coordinates with the inner conical surface 22 of sleeve pipe 20, insertion rod 10 partial insertion The cylindrical hole of intermediate plate 30, intermediate plate 30 is under the pushing of spring 40 and the constraint of inner conical surface 22 of sleeve pipe 20 Under, its cylindrical hole holds the insertion portion of insertion rod 10 tightly.

When using connector attached article 1 of the present utility model with object 3, object 1 gets out a summary Less than the hole of insertion rod 10, the degree of depth that its degree of depth is to be inserted equal to insertion rod 10, insertion rod 10 is inserted In this hole on object 1, hole keeps holding state tightly with the insertion portion of insertion rod 10；Object 3 bores Going out a hole being slightly less than sleeve pipe 20 external diameter, its degree of depth is equal to the length of sleeve pipe 20, by sleeve pipe 20 and folder Sheet 30, spring 40 insert in this hole after assembling；By the exposed portion of the insertion rod 10 on object 1 with On object 3, the cylindrical hole of the intermediate plate 30 in sleeve pipe 20 is directed at and is inserted, when object 1 and object 3 Surface 2 when fitting, object 1 and object 3 i.e. realize being reliably connected by connector.

In the embodiment in figure 1, the bottom at sleeve pipe 20 arranges base plate, it is ensured that sleeve pipe 20 and intermediate plate 30, after spring 40 assembles, time in the connector installing hole inserted on object 3, different in installing hole Thing does not results in impact to spring 40.

In the embodiment of fig. 2, the mouth end of sleeve pipe 20, bottom is opening, it is also possible to realize this practicality Novel goal of the invention.

As shown in Figure 4, Figure 5, in order to improve the clamping force of intermediate plate 30 and insertion rod 10 insertion portion, The cylindrical hole surface configuration reticulation patterns structure of intermediate plate or transversely arrange ring-type on the cylindrical hole surface of intermediate plate Bulge-structure 33.

In order to improve the clamping force of intermediate plate 30 and insertion rod 10 insertion portion, it is also possible in insertion rod Reticulation patterns or the annular groove adaptive with the annular protrusion that intermediate plate 30 is arranged are set on the side surface of 10.

It is typically inserted in the cylindrical hole that bar 10 partial insertion is connected object 1, partial insertion intermediate plate 30, i.e. Can realize connecting.For realizing reliable reasonably connection, the twice of a length of sleeve pipe 20 of insertion rod 10 is set. So, the cylindrical hole of the intermediate plate 30 in insertion rod 10 half insertion sleeve pipe 20 is interior and is pushed into sleeve pipe 20 bottom, Second half inserts in the hole of connected object 1, can improve the reliability of connection.

In the embodiment of Fig. 1, Fig. 2, sleeve pipe 20 uses cylindrical outer shape.As it is shown on figure 3, the side of being Just sleeve pipe 20 is inserted in the hole of connected thing 3, the profile of sleeve pipe 20 is set to cone, and makes set The diameter of the bottom 24 of pipe 20 is less than the diameter of mouth end 21, it is ensured that the half of sleeve pipe 20 coning angle a is less than Equal to angle of friction.So, it is ensured that sleeve pipe 20 inserts the Kong Zhonghou of connected thing 3, realizes self-locking with hole, Prevent sleeve pipe 20 from deviating from from the hole of connected thing 3.

As it is shown in figure 1, during insertion rod 10 inserts the cylindrical hole of intermediate plate 30 smoothly for convenience, at intermediate plate The small end cylindrical hole port of 30 is provided with filleted corner 31.In other embodiments, at the small end circle of intermediate plate 30 Post holes port could be arranged to chamfering or bull nose.
