As Figure 1-4, internal lock rivet comprises the collar 1, rivet mandrel 5, the collar 1 comprises the integrated straight shape sleeve 1a that is communicated with up and down and collar head 1b, the internal diameter La of straight shape sleeve 1a is greater than the internal diameter Lb of collar head 1b, the connecting part of straight shape sleeve 1a and collar head 1b is junction surface 2, this junction surface 2 forms the collar locking slot in order to locking rivet mandrel 5, accordingly, rivet mandrel 5 is provided with the mandrel locking slot 6 mated with collar locking slot, during to fix the first workpiece 3 with second workpiece 4, rivet mandrel 5 inserts the collar 1 and is connected with the collar 1 interference fit, the mandrel locking slot 6 of the rivet mandrel 5 that interference connects contacts with each other with the collar locking slot of the collar 1, empty in mandrel locking slot 6 after interference connects, so just cause the anti-seismic performance of internal lock rivet poor.In order to address this problem, at present junction surface 2 is arranged to horizontal by certain angle, near one end lower than the junction surface 2 away from the collar 1 central shaft, one end of the junction surface 2 of the collar 1 central shaft, stuffing is formed from the minimum point of junction surface 2 to the collar 1 between the peak of junction surface 2, stuffing is to be packed in mandrel locking slot 6, then need to overcome the attachment force when snatching force that provides to stuffing when stuffing is connected with straight shape sleeve 1a inwall and stuffing are connected with junction surface 2 upper-end surface, in addition, because stuffing is away from the central shaft away from the collar 1, cause current this kind of filling effect poor, notably, this stuffing cannot be inserted in mandrel locking slot 6, still certain space S is there is in mandrel locking slot 6.
Model utility content
For solving the problems of the technologies described above, the purpose of this utility model is to provide a kind of stuffing to be easy to the internal lock rivet inserted in mandrel locking slot.
For achieving the above object, the technical solution of the utility model is as follows: a kind of internal lock rivet, comprise the collar, the described collar comprises the integrated straight shape sleeve that is communicated with up and down and collar head, the internal diameter of described straight shape sleeve is greater than the internal diameter of collar head, the connecting part of described straight shape sleeve and collar head is junction surface, and described junction surface is horizontal by certain angle, and one end of the described junction surface near collar central shaft is higher than one end of the junction surface away from collar central shaft.
Preferably, described junction surface is plane.
Preferably, the lateral section at the two ends of described junction surface is all in arc-shaped.
The beneficial effect of employing the technical program is: near one end higher than the junction surface away from collar central shaft, one end of the junction surface of collar central shaft, stuffing is formed from the minimum point of junction surface to the collar between the peak of junction surface, stuffing is near the central shaft of the collar, near one end lower than the junction surface away from collar central shaft, one end of the junction surface of collar central shaft in prior art, stuffing is to be packed in mandrel locking slot, without the need to overcoming the snatching force provided to stuffing when stuffing is connected with straight shape sleeve lining again, then stuffing is easy to be packed in mandrel locking slot, and can be packed into completely in mandrel locking slot, ensure that mandrel locking slot is no longer empty, improve the anti-seismic performance of internal lock rivet.

Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technological scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Consult shown in Fig. 5 to Fig. 8, a kind of internal lock rivet, comprise the collar 7, the collar 7 comprises the integrated straight shape sleeve 7a that is communicated with up and down and collar head 7b, the internal diameter La ' of straight shape sleeve 7a is greater than the internal diameter Lb ' of collar head 7b, the connecting part of straight shape sleeve 7a and collar head 7b is junction surface 8, junction surface 8 horizontal by certain angle, near one end of the junction surface 8 of the collar 7 central shaft higher than the one end of the junction surface 8 away from the collar 7 central shaft.This junction surface 8 forms collar locking slot.
Identical with prior art is, rivet mandrel 5 is provided with the mandrel locking slot 6 mated with collar locking slot, during to fix the first workpiece 3 with second workpiece 4, rivet mandrel 5 inserts the collar 7 and is connected with the collar 7 interference fit, the mandrel locking slot 6 of the rivet mandrel 5 that interference connects contacts with each other with the collar locking slot of the collar 7, because one end of the junction surface 8 near the collar 7 central shaft is higher than the one end of the junction surface 8 away from the collar 7 central shaft, stuffing X is formed from the minimum point of junction surface 8 to the collar 7 between the peak of junction surface 8, and stuffing X is near the central shaft of the collar 7, in addition, stuffing X is to be packed in mandrel locking slot 6, without the need to overcoming the snatching force provided to stuffing X when stuffing X is connected with straight shape sleeve 7a inwall again, in interference connection procedure, the upper diapire of mandrel locking slot 6 is easy to stuffing X to be pressed in mandrel locking slot 6, and stuffing X can be packed in mandrel locking slot 6 completely, ensure that mandrel locking slot 6 is no longer empty, improve the anti-seismic performance of internal lock rivet.
