Described branch sleeve both ends of the surface tapering is less than the tapering of cavity in pullover.
Described branch sleeve both ends are provided with four shrinkage joints respectively, and described shrinkage joint is a V-arrangement.
The taper seat at described branch sleeve two ends is the straight line conical surface or the arcuation conical surface; Described pullover cavity is and the corresponding straight line conical surface of sleeve two ends shape or the arcuation conical surface.
The taper seat and the pullover cavity at described branch sleeve two ends are provided with anti-skidding ratchet.
The tapering of the taper seat at described branch sleeve two ends is 5-65 °; The tapering of described pullover cavity is 5-65 °.
The tapering of the taper seat at described branch sleeve two ends is 8-45 °; The tapering of described pullover cavity is 8-45 °.
The tapering of the taper seat at described branch sleeve two ends is 12-30 °; The tapering of described pullover cavity is 12-30 °.
The tapering of the taper seat at described branch sleeve two ends is 8 °; The tapering of described pullover cavity is 12 °.
The beneficial effects of the utility model are: the utility model is applicable to the connection of minor diameter reinforcing bar, the bonding strength height, and stability is strong, processing is simple, and is with low cost, easy for installation, be fit to very much the construction site Fast Installation, saving of work and time has higher utility and promotion prospect.

The specific embodiment
Embodiment 1:
As shown in Figure 1, 2, the simple and easy minor diameter reinforcing bar connector of the utility model is used for the connection of end through the minor diameter reinforcing bar 3 of jumping-up processing, and the general jumping-up in reinforcing bar 3 ends is the frustum shape, with connector two sections reinforcing bars 3 is connected then.Connector comprises a hollow branch sleeve 1, and branch sleeve 1 diameter is with end reinforced identical, and the two ends of branch sleeve 1 are truncated cone shape; The two ends of branch sleeve 1 cooperate respectively and are equipped with pullover 2, pullover 2 is hollow tube-shape, the truncated cone shape of pullover 2 cavity for matching with branch sleeve 1 both ends, the both ends of the surface tapering of branch sleeve 1 is less than the tapering of pullover 2 interior cavitys, the two terminal circle conical surface of branch sleeve 1 is the straight line conical surface in the present embodiment, tapering is 8 °, pullover 2 cavity also be the straight line conical surface, tapering is 12 °.
The structure of branch sleeve is shown in Fig. 7,8, shown in Fig. 7,8, branch sleeve of the present utility model middle part is cylindric, diminish gradually to the both sides diameter from the middle part, thereby embarking on journey for any lateral section is trapezoidal, profile is circular cone shape, the both ends of branch sleeve inwardly have " V " shrinkage joint 1 ' respectively, and every side end is offered four shrinkage joints 1 ' respectively.
During actual installation, at first reinforcing bar 3 alignment that both ends are handled through jumping-up, entangle with branch sleeve 1 afterwards, then with two pullover 2 both ends of the surface of entangling branch sleeve 1 respectively, make pullover 2 as far as possible close to the junction of two reinforcing bars with external force, the conical surface at conical surface extruding branch sleeve 1 two ends in pullover 2, because the extruding of external force, make shrinkage joint 1 ' shrink, until closing fully, thereby make branch sleeve maximization distortion, final state is the external surface that the cavity in the branch sleeve 1 is pressed close to reinforcing bar, reason owing to end reinforced tapering makes it can not withdraw from branch sleeve 1 like this, adds pullover 2 compressing, has promptly formed high strength, stable connection.
Embodiment 2:
Shown in Fig. 3,4, the difference of present embodiment and embodiment 1 is, for stiffener 3 bonding strengths and stability, prevent to cause pullover 2 slippages from the branch sleeve 1 because of vibrations or other reason, be provided with anti-skidding ratchet 4 on the taper seat at branch sleeve 1 two ends, pullover 2 interior cavitys are provided with the anti-skidding ratchet 4 ' that cooperates with anti-skidding ratchet 4.
Embodiment 3:
Shown in Fig. 5,6, the difference of present embodiment and embodiment 1 is, the taper seat at branch sleeve 1 two ends is the arcuation conical surface, and the cavitys in pullover 2 be the arcuation conical surface that cooperates with aforementioned taper seat, be easy to install and to bonding strength with stable without any weakening.
The utility model also can have other variation; as well known to the skilled person; the foregoing description only plays the exemplary role in the above-mentioned utility model protection scope; for those of ordinary skills; also have a lot of conventional distortion and other embodiment in the protection domain that the utility model limited, these distortion and embodiment will be within the protection domains that the utility model awaits the reply.
