Description

Quick Fixing Device

technical field

The utility model relates to a fast fastening device, in particular to an improved fast fastening device which can be used for quickly assembling two boards.

Background technique

The known fastening assembly for connecting two boards usually adopts the technical feature of screw locking, and its specific implementation includes a screw, a sleeve cover and a sleeve to form a fastening assembly; wherein, one end of the screw has a force-receiving part, The force-bearing part is provided with a screwdriver slot, and the other end has a screw rod connected with the force-bearing part; the cover fits on the hollow tube around the force-bearing part of the screw to cover and protect the screw; and the sleeve fits The screw on the screw. Therefore, the fixed assembly can be combined with the cover on the first board, and then the first board is moved to align with the second board, so that the screw rod of the screw corresponds to the lock hole of the first board and the second board , and then use a tool to apply a rotating external force to the screwdriver groove of the screw force receiving part, and then lock the screw in the lock hole of the second plate body, thereby completing the combined structure connecting the two plate bodies. The above-mentioned technical feature of screw locking can combine the two boards, but when assembling, tools must be used to apply external force to the screwdriver groove of the screw force receiving part, which makes the assembly process more cumbersome.

Therefore, those skilled in the art propose a design of a fast fastening assembly, as shown in FIG. 1 , which includes a fastening assembly 10 and a latch 20; 101 fastening column 102, and the socket 103 that runs through the cap 101 and the fastening column 102, and the end of the fastening column 102 is provided with an axially extending slit to form a plurality of elastically shrinkable fastening piece 104, and a hook portion 105 is provided on the outside of the fastening piece 104; the latch 20 has a column portion 201 and a cap portion 202, so that the column portion 201 is inserted into the socket 103 of the fastening assembly 10 to prevent the fastening piece 104 from Shrink at will. When the fast fastening assembly wants to assemble the two plates 30, 40, first pull the latch 20 toward the cap portion 101 of the fastening assembly 10, so that the fastening piece 104 can shrink, and then pass through the two plates 30, 40 After the perforation 301, 401 is completed, the pin 20 is pressed down, so that the column part 201 resists the buckle piece 104, and the buckle piece 104 cannot be contracted, thus completing the buckle assembly. However, when the bolt 20 is used, it still has the defect of being pulled out or loosened in the opposite direction, and will lose the effect of restricting the buckle piece 104, causing the hook portion 105 of the buckle assembly 10 to break away from the perforation 301 of the two boards 30, 40 , 401.
