Utility model content
The utility model overcomes the deficiency that prior art exists, technical problem to be solved be to provide a kind of reinforcing bar or steel pipe easy to connect, fast rapid abutting joint clamping connection splicer accurately.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: the rapid abutting joint clamping connection splicer of a kind of reinforcing bar or steel pipe, comprise outer sleeve, inner sleeve and wedge grip lobe, the two ends of outer sleeve are equipped with a convex shape link slot, the path groove of two convex shape link slots is oppositely arranged and centre is provided with blind plate, in the large footpath groove of each described convex shape link slot, all by screw thread, an inner sleeve is installed, the outer face of inner sleeve is provided with tense-lax keyway, in each inner sleeve, be all movably installed with multiple wedge grip lobes, multiple wedge grip lobes are provided with the Rotary-table of through hole in the middle of forming and the bottom surface of Rotary-table is inside, described multiple wedge grip lobe is the inclined-plane matching with the contact surface of inner sleeve, the Rotary-table bottom surface annulus external diameter of described multiple wedge grip lobe compositions is greater than the path groove diameter of convex shape link slot.
In the path groove of described two convex shape link slots, be separately installed with a regulating spring, one end of described regulating spring contacts with the bottom surface of corresponding multiple wedge grip lobes near blind plate and the other end.
In the opposed inner walls of described multiple wedge grip lobes, be equipped with multiple tracks and compress tooth.
The centre of described blind plate has the diameter that through hole and through-hole diameter are less than reinforcing bar or steel pipe.
Three wedge grip lobes are installed in described each inner sleeve.
Transition shoulder between large footpath groove and the path groove of described convex shape link slot is inclined plane.
The beneficial effect that the utility model compared with the existing technology had is: the combination of inner sleeve and multiple wedge grip lobes is set at outer sleeve two ends, inner sleeve is arranged on inside, outer sleeve two ends by screw thread and is regulated and compressed multiple wedge grip lobes by tense-lax keyway, make it clamp middle reinforcing bar or steel pipe, the end of realizing two reinforcing bars or steel pipe connects, convenient and swift, and quality of fit is high, on-the-spot reinforcing bar or steel tube head need not secondary operations, solve on-the-spot processed filament head and factory process sleeve internal thread is worked poor, docking steel pipe axiality is poor, low bearing capacity, easily produce the defect of unstability, between blind plate and wedge grip lobe, regulating spring is set, regulating spring makes wedge grip lobe have an adjustable elastic space, make to be connect reinforcing bar or steel pipe and can insert smoothly and hold out against central blind plate, can make multiple wedge grip lobes under the effect of regulating spring, keep globality and can extend application life of the present utility model simultaneously, multiple tracks is set in wedge grip lobe opposed inner walls and compresses tooth, in the time tightening inner sleeve and make wedge grip lobe fix the end of reinforcing bar or steel pipe, compressing tooth has increased the frictional force between wedge grip lobe and reinforcing bar or steel pipe, connects more fastening reliable, through hole in the middle of blind plate makes, in the time of joint steel pipe, can realize linkage function of the present utility model, does not affect again the circulation of steel pipe.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Fig. 3 is mounting structure schematic diagram of the present utility model.
In figure: 1 is outer sleeve, 2 is inner sleeve, and 3 is wedge grip lobe, and 4 is blind plate, and 5 is tense-lax keyway, and 6 is regulating spring, and 7 is reinforcing bar or steel pipe, and 8 is elastic space.
The specific embodiment
As Figure 1-3, the rapid abutting joint clamping connection splicer of a kind of reinforcing bar of the utility model or steel pipe, comprise outer sleeve 1, inner sleeve 2 and wedge grip lobe 3, the two ends of outer sleeve 1 are equipped with a convex shape link slot, the path groove of two convex shape link slots is oppositely arranged and centre is provided with blind plate 4, in the large footpath groove of each described convex shape link slot, all by screw thread, an inner sleeve 2 is installed, the outer face of inner sleeve 2 is provided with tense-lax keyway 5, each inner sleeve 2 is interior is all movably installed with multiple wedge grip lobes 3, multiple wedge grip lobes 3 composition centres are provided with the Rotary-table of through hole and the bottom surface of Rotary-table is inside, described multiple wedge grip lobe 3 is the inclined-plane matching with the contact surface of inner sleeve 2, the Rotary-table bottom surface annulus external diameter that described multiple wedge grip lobe 3 forms is greater than the path groove diameter of convex shape link slot.
In the path groove of described two convex shape link slots, be separately installed with a regulating spring 6, one end of described regulating spring 6 contacts with the bottom surface of corresponding multiple wedge grip lobes 3 near blind plate 4 and the other end.
In the opposed inner walls of described multiple wedge grip lobes 3, be equipped with multiple tracks and compress tooth.
The centre of described blind plate 4 has the diameter that through hole and through-hole diameter are less than reinforcing bar or steel pipe 7.
Three wedge grip lobes 3 are installed in described each inner sleeve 2.
Transition shoulder between large footpath groove and the path groove of described convex shape link slot is inclined plane.
The above convex shape link slot is that two circular grooves are connected that to make its cutting plane be " protruding " font.
Using method
The convex shape link slot internal direct that the utility model two ends are stretched into by the holes in the middle of multiple wedge grip lobes 3 respectively in the end of two reinforcing bars to be connected or steel pipe 7 is to holding out against blind plate 4, now inner sleeve 2 some stretch out outer sleeve 1 outside, the structure that inner sleeve 2 contacts with multiple wedge grip lobes 3 inclined-planes makes it can not fixed wedge clevis lobe 3, regulating spring 6 withstands wedge grip lobe 3, reinforcing bar or steel pipe 7 can be inserted smoothly and to 3 one elastic spaces 8 of wedge grip lobe, as shown in Figure 1;
Respectively two inner sleeves 2 are screwed to the inside of outer sleeve 1 by tense-lax keyway 5 with U-shaped spanner or F type spanner, inner sleeve 2 is in the time moving to outer sleeve 1 is inner, also can withstand on the transition shoulder of convex shape link slot to it by dog wedge clevis lobe 3 simultaneously, now the elastic space 8 of wedge grip lobe 3 disappears, compression tooth on wedge grip lobe 3 inwalls is close to reinforcing bar or steel pipe 7, strengthen frictional force, compressing reinforcing bar or steel pipe 7 can not move freely it, formation can be subject to the connecting rod of tension and compression, achieve a fixed connection, dock convenient and swift, need not on-the-spot secondary operations, not high to operator's technical requirements, the rod member axiality that docking forms is good, be difficult for producing unstability, supporting capacity is high, there is comprehensive significant beneficial effect.
