Detailed Description

As shown in the accompanying drawings 1-3, the utility model discloses a vibration frame 1 and the proportion platform frame 2 of setting on vibration frame 1, one side and the vibration frame 1 hinge of 2 width directions of frame, the opposite side is connected through calliper 6 fast with vibration frame 1, only need when frame 2 is opened to needs open the calliper 6 fast can, do not have the bolted connection form, can improve the convenience of opening.

The utility model discloses a vibration frame 1 adopts specific loose joint bolt connecting device to articulate with frame 2, as shown in figure 3, loose joint bolt connecting device is including fixing unable adjustment base 7 on vibration frame 1 lateral wall, through installing loose joint bolt 8 on unable adjustment base 7, fix connection base 9 on frame 2 lateral wall and set up the round pin axle 10 on connecting base 9, round pin axle 10 passes the connecting hole at loose joint bolt 8 top, install loose joint bolt 8 and connect base 9 and just loose joint bolt 8 can rotate around the round pin axle together, be equipped with the screw hole on unable adjustment base 7, loose joint bolt 8 passes through threaded connection with the screw hole, thereby realize the hinge between vibration frame 1 and frame 2. After the pin shaft 10 is disassembled, the height of the top connecting hole can be adjusted by screwing the loose joint bolt 8, the sealing performance between the specific gravity table frame and the vibration frame when the specific gravity table frame falls down is ensured, the fastening of the specific gravity table in the running state is also ensured, and the hinge structure is more stable and reliable compared with the traditional hinge structure.

As the utility model discloses a further improvement, unable adjustment base 7 and connection base 9 are all installed on the vibration frame 1 and the frame 2 that correspond through the bolt, and it is more convenient to dismantle the installation, has promoted assembly efficiency. The connecting base 9 comprises two L-shaped plates which are arranged in a back-to-back mode, one side face of each L-shaped plate is fixedly connected with the frame 2, a gap is reserved between the other side faces of the two L-shaped plates, the top of the loose joint bolt 8 is located in the gap, the pin shaft 10 penetrates through connecting holes in the tops of the two L-shaped plates and the loose joint bolt 8, and the loose joint bolt 8 can rotate in the gap.

Be equipped with air spring 3 at the bottom surface both ends of frame 2, the other end and the vibration frame 1 of air spring 3 are connected, are equipped with bracing piece 4 at the opposite side hinge of 2 width direction of frame, and the upper end and the 2 hinges of frame of this bracing piece 4, and the back is opened in the upset of frame 2, and the lower extreme and the vibration frame 1 contact of bracing piece 4 play the supporting role, prevent that frame 2 from falling.
