Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of fast installation assembly field, especially a kind of scissor fork quick assembly mechanism. BACKGROUND

[0002] The torsion spring and tension spring are on the switch cabinet flap opening switch, and the upper connecting plate or the lower connecting plate is moved by artificial mode previously, so that the bending plate on the switch cabinet flap opening switch is rotated and adheres to the fixed plate, then is fastened together by bolt, so that the bending plate on the switch cabinet flap opening switch has the set elastic force between the upper connecting plate and the lower connecting plate, so as to drive the upper connecting plate or the lower connecting plate to rotate and then loosen, the upper connecting plate or the lower connecting plate will have enough reset elastic force, so as to open the door on the switch cabinet or other rotating parts needed to be opened, the traditional way of moving the bending plate to rotate and adhere to the fixed plate by artificial and then fastening together by bolt is not only time-consuming and laborious, but also has low efficiency of assembling the switch cabinet flap opening switch, and also has certain danger (the upper connecting plate or the lower connecting plate will rebound back when bolt is not fastened in place in the case of hand slip or unstable movement, so as to hit the worker's hand), which is not conducive to large-scale popularization and installation. SUMMARY

[0003] The utility model solves the above-mentioned prior art defects, and provides a kind of scissor fork quick assembly mechanism capable of quickly and efficiently assembling switch cabinet flap opening switch, which meets the needs of efficient, fast and accurate assembly.

[0004] The utility model discloses a technical scheme for solving the technical problem: the scissor fork quick assembly mechanism includes a base, a first double-shaft air cylinder is fixed on the base, a first vertical rod is screwed on the base opposite the first double-shaft air cylinder, and a first tightening gap is provided on the first vertical rod; a limiting block shaped like a three-sided square is fixed on the base, a horizontal rack is fixed on the base above the limiting block, an air cylinder is fixed on the horizontal rack, and a pressure head is installed on the piston rod of the air cylinder. The limiting block can place the fixed plate on the switch cabinet flap opening switch in the limiting block and install the parts stacked together, thereby achieving horizontal limiting. The horizontal rack, air cylinder and pressure head can vertically limit the switch cabinet flap opening switch assembled together by the pressure head when the air cylinder is started, preventing the lower connecting plate from running out of the limiting block due to uneven stress when being pressed. The first double-shaft air cylinder and the first vertical rod can push the lower connecting plate to rotate by the push block on the first double-shaft air cylinder, twist the torsion spring to store energy, and make the bending plate rotate and align with the fixed plate after adhering to it, and then fasten together with the bolt. This can greatly increase the installation efficiency of the switch cabinet flap opening switch and make it safer. The first tightening gap can facilitate the tool to be clamped in the first tightening gap and rotated, thereby being screwed on the base.

[0005] Further improvement, the left side of the first vertical rod is provided with a second vertical rod screwed on the base, a second tightening gap is arranged on the second vertical rod, and the right side of the first vertical rod is provided with a second double-shaft air cylinder fixed on the base. Here, the second vertical rod and the second double-shaft air cylinder can install switch cabinet flap opening switches in different directions. Some switch cabinet flap opening switches need to press the upper connecting plate to support the lower connecting plate, and some switch cabinet flap opening switches need to press the lower connecting plate to support the upper connecting plate. The second tightening gap can be conveniently clamped and rotated by a tool, so as to be screwed on the base.

[0006] Further improvement, the bottom end of the first vertical rod and the second vertical rod is provided with a threaded hole, and a countersunk head bolt is installed on the base and screwed with the threaded hole. The threaded hole and the countersunk head bolt can further fasten the first vertical rod and the second vertical rod to the base, avoiding loosening of the first vertical rod and the second vertical rod after long-term use.

[0007] Further improvement, a group of notches are arranged on the push block of the first double-shaft air cylinder and the second double-shaft air cylinder, and the notches are arranged along the length direction of the push block. The notches are inverted triangular. The notches can prevent the push block from slipping when pushing the upper connecting plate or the lower connecting plate, and the assembly efficiency is higher.

[0008] Further improvement, adjusting feet are installed on the four corners of the base, and nuts are threadedly connected to the adjusting feet. The adjusting feet can make the base more stable on the table top, and can also be used on uneven table top. The nuts can lock the adjusting feet in position after adjusting the height, preventing loosening and displacement of the adjusting feet after long-term use.

[0009] The beneficial effects of the utility model are as follows:

[0010] 1. The first vertical rod can block the upper connecting plate on one side, so that the first double-shaft air cylinder can push the lower connecting plate to rotate the bent plate and pair with the threaded hole of the fixed plate, and then assemble the bolt.

[0011] 2. The second vertical rod and the second double-shaft air cylinder can rotate the bent plate in different directions and pair with the threaded hole of the fixed plate, and then assemble the bolt.

[0012] 3. The countersunk head bolt can stabilize the first vertical rod and the second vertical rod on the base without loosening. BRIEF DESCRIPTION OF DRAWINGS
