Location shell, plural pieces spring leaf and a plurality of location steel spring plate, the quantity of described spring leaf and described location spring steel
Plate quantity is equal；Steel spring plate interval, described location is fixed on inside the shell of described location, and described location is located at by described spring leaf
Between steel spring plate, described tapered end is fixed in the middle of described spring leaf, and the one end of described connecting pin is connected to described tapered end.
Further, described tapered end is one cylindric, and described tapered end is longitudinally cut at least two pieces of lock dogs, and described tapered end includes
One steel spring plate buckle, described lock dog is fixed by described steel spring plate buckle, is provided with a groove, described groove in described tapered end
It is connected to described connecting pin one end.
Further, being provided with fixing teeth in described groove, the one end of described connecting pin is provided with connection teeth, described solid
Determine teeth and be connected teeth occlusion with described.
Further, described connecting pin one end is equipped with a plurality of connection teeth, and each described connection teeth are 44 ° of saws
Profile of tooth.
Further, the distance of two adjacent connection teeth is 2.5mm.
Further, the other end of described connecting pin is provided with helicitic texture.
Further, described location steel spring plate uniform intervals is fixed on inside the shell of described location.
Further, form one inside steel spring plate both ends, each described location and described location shell and fix groove, use
In stationary spring.
Further, the both ends of described connecting pin are cylindric.
It is an advantage of the current invention that: one of the present invention expand biting connecions mechanical connecting joint, 1, the function compared on market,
Weight, size have had the biggest reducing, and reduce rolled steel dosage, save manufacturing cost；2, working security is improved, and as received basis
Amount, by square hole connecting pin changes into cylinder connecting pin, improves joint occlusion site area and unit tension, and single joint resists
Pulling force is more than 170KN；Meanwhile, accelerating construction progress and installation quality；3, three flat spring sheets, the longest are set up in the shell of location
30mm* width 15mm* thickness 1.2mm, can expand tapered end to center draw-in groove and carry out centralized positioning, improve speed of application and connect matter
Amount；4, use supporting auxiliary equipment, improve construction speed and construction quality, reduce hand labor intensity.

Detailed description of the invention
Referring to shown in Fig. 1 to Fig. 3, the present invention expands biting connecions mechanical connecting joint, including connecting pin 1, tapered end
2, a location shell 3, plural pieces spring leaf 4 and a plurality of location steel spring plate 5, the quantity of described spring leaf 4 is fixed with described
Position steel spring plate 5 quantity is equal；Steel spring plate 5 interval, described location is fixed on inside described location shell 3, described spring leaf 4
Being located between described location steel spring plate 5, described tapered end 2 is fixed in the middle of described spring leaf 4, uses spring leaf to carry out 360 degree
Location, in work progress, it is ensured that tapered end is in the middle part of location shell 3, it is simple to scene aligns construction；Described connecting pin 1
One end is connected to described tapered end 2, and the other end of described connecting pin 1 is provided with helicitic texture, and described location steel spring plate 5 is uniform
Interval is fixed on inside described location shell 3, shape inside steel spring plate 5 both ends, each described location and described location shell 3
Becoming one to fix groove, for stationary spring 4, the both ends of described connecting pin 1 are cylindric；Described location shell 3 is hollow
Cylindric.
Described tapered end 2 is one cylindric, and described tapered end 2 is longitudinally cut at least two pieces of lock dogs 21 (as shown in Figure 3), described lock
