Detailed Description
As shown in fig. 1 to 4, a fixing fixture for door pretreatment electrophoresis and paint spraying, comprising:
the first locking part 1, the first locking part 1 comprises a first locking piece 1-1 which can clamp the door frame A. The second locking part 2 comprises a second locking piece 2-1 which can clamp the vehicle door.
A connecting part 3 including a first connecting part 3-1 rotatable around a central axis of the first locking part 1 and a second connecting part 3-2 fixedly connected with the second locking part 2; the first connecting portion 3-1 and the second connecting portion 3-2 are rotatably connected to each other so that the second connecting portion 3-2 has a first position supported between the door and the door frame a and a second position drooping down in the door frame a by gravity.
A fixing portion 4, wherein the fixing portion 4 is provided with a magnet 4-1, and the fixing portion 4 is connected with the first locking portion 1; when the second connecting portion 3-2 is located at the second position, the door frame a can fix the door by the magnet 4-1.
As a preferred embodiment of the present application, as shown in fig. 2, the first locking member 1-1 includes a first locking groove 1-1-1 and a first clamping screw 1-1-2, the first locking groove 1-1 can be embedded in the door frame, and the first locking portion 1 can be fixed to the door frame a after screwing the first clamping screw 1-1-2 into the first locking groove 1-1.
As a preferred embodiment of the present application, the second locking member 2-1 includes a second locking groove 2-1-1 and a second clamping screw 2-1-2, the second locking groove 2-1-1 is insertable into a mounting frame of the door glass, and the second locking portion 2 is fixed after screwing the second clamping screw 2-1-2 into the second locking groove 2-1-1.
As a preferred embodiment of the present application, the first connecting portion 3-1 is connected to the first locking portion 1 at a connection position through a rotation shaft, so that the first connecting portion 3-1 can rotate around the first locking portion 1, and further drives the second connecting portion 3-2 and the second locking portion 2 to rotate.
As a preferred embodiment of the present application, the inner side of the first connection part 3-1 and the inner side of the second connection part 3-2 are connected by a bolt shaft, and the first connection part 3-1 at the connection position is in the shape of an ear plate to provide a sufficient rotation space for the second connection part 3-2.
As a preferred embodiment of the present application, the second connecting portion 3-2 and the second locking portion 2 are designed as an integral member, so that the integrity of the portion can be improved, the supporting strength can be improved, and the supporting of the second connecting portion 3-2 to the vehicle door can be more stable.
As a preferred embodiment of the present application, a magnet 4-1 insert is provided in the first locking portion 1, the magnet 4-1 insert has a rectangular box shape with an opening 4-2-1, the magnet 4-1 is fixed inside by a countersunk screw, and the top of the magnet 4-1 slightly protrudes from the opening 4-2-1, so that when the second connecting portion 3-2 is located at the first position, the magnet 4-1 can adsorb the door B to fix the door B.
