Specific embodiment
In order to further illustrate the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments, but not
They can be interpreted as limiting the scope of the present invention.
As shown in Figure 1, a kind of ellipsoid formula rebar connector of the present invention, includes tapered end (1) and lock body (2), the steel
It is processed into shape of threads in muscle end.
As shown in Fig. 2,4,8, tapered end (1) includes upper sleeve (1-2), and the top upper sleeve (1-2) is provided with bolt
Hole (1-1).As shown in fig. 6, upper sleeve (1-2) is internally provided with empty slot (1-3), empty slot (1-3) is consisted of three parts: top
Elliposoidal empty slot (1-3-1), middle part cylinder empty slot (1-3-2), lower part empty slot (1-3-3), top elliposoidal empty slot (1-3-1)
Diameter be slightly larger than the diameter of middle part cylinder empty slot (1-3-2), be provided with two on middle part cylinder empty slot (1-3-2) excircle
Semi-circular steel disc (1-4), the outboard end of semi-circular steel disc (1-4) are provided with spring (1-5), two halves annular steel disc (1-4) composition
One annulus is connect between annular steel disc (1-4) and upper sleeve (1-2) by spring (1-5)；Annular steel disc is by by interior
When extruding force outward, squeezing spring, to enter upper sleeve (1-2) internal.The upper sleeve (1-2) and lower sleeve portion
(2-2) is steel sleeve.
As shown in Fig. 3,5, lock body (2) includes lower sleeve portion (2-2) and cylinder (2-3), is provided with bolt in lower sleeve portion
Hole (2-1).As shown in fig. 7, cylinder (2-3) consists of three parts: top elliposoidal cylinder (2-3-1), middle part cylindrical column
(2-3-2), lower part cylinder (2-3-3)；The diameter of top elliposoidal cylinder (2-3-1) is slightly larger than middle part cylindrical column (2-3-
2) diameter, cylinder (2-3) and the shape of empty slot (1-3) match.
Application method of the invention is as follows:
It is processed into shape of threads by end reinforced, a reinforcing bar one end is screwed into the bolt hole (1-1) of tapered end (1), until bolt
The fastening of hole lower end, another reinforcing bar one end is screwed into the bolt hole (2-1) of lock body (2), until bolt hole upper end fastens；It will lock
In the empty slot (1-3) of cylinder (2-3) insertion tapered end (1) lower part of body (2)；Elliposoidal cylinder (2-3-1) struts semi-circular steel disc
(1-4) is inserted into elliposoidal empty slot (1-3-1), annular steel disc (1-4) retraction upper sleeve by extruding force from inside to outside
(1-2) is internal, when elliposoidal cylinder enters top elliposoidal empty slot (1-3-1) of empty slot (1-3), two and half in tapered end (1)
Annular steel disc (1-4) is popped up under the elastic force effect of spring (1-5), blocks portion cylindrical column (2-3-2) in the middle part of cylinder (2-3)
Point, the lower part cylinder (2-3-3) of the cylinder (2-3) of lock body (2) then enters in tapered end (1) lower part empty slot (1-3-3), completes reinforcing bar
Connection.After connection, lock body (2) top elliposoidal cylinder (2-3-1) is simultaneously by tapered end (1) upper sleeve (1-2)
Extruding between and between annular steel disc (1-4) is all connected with securely under reinforcing bar tension and compression state.
The above is only a preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications are also answered
