Detailed Description

The invention will be further elucidated and described with reference to the following embodiments and drawings in which:

example one

Referring to fig. 1, the self-locking folder includes a first joint 10, a second joint 20 and a handle 30, wherein one side of the first joint 10 is hinged to one side of the second joint 20 through a first hinge shaft 40, and one end of the handle 30 is hinged to the other side of the first joint 10 through a second hinge shaft 50.

The second connector 20 is provided with a concave portion 21 and an adjusting screw hole 22, an adjusting screw 23 is arranged in the adjusting screw hole 22, and one end of the adjusting screw 23 is opposite to the handle 30.

The handle 30 is provided with a first side wall 31 and a second side wall 32, the first side wall 31 is provided with a first hinge hole 311 and a limiting groove 312, and the second side wall 32 is provided with a second hinge hole 321. The handle 30 is provided with a self-locking pin 33, a torsion spring 34, a push rod 35, a return spring 37, a self-locking bolt 38 and a sliding button 36, the self-locking pin 33 is arranged in a first hinge hole 311 and a second hinge hole 321, the self-locking pin 33 is provided with a self-locking hole and a connecting hole, the torsion spring 34 is sleeved on the self-locking pin 33, one end of the torsion spring is abutted to the self-locking pin 33, the other end of the torsion spring is abutted to the second side wall 32 of the handle 30, the push rod 35 is arranged in the connecting hole, one end of the push rod 35 is a ball head, the self-locking pin 33 deflects under the action of the torsion spring 34 to enable the connecting hole to be obliquely arranged, namely in a non-vertical direction, the sliding button 36 is provided with a boss 361312, return spring 37 one end butt first lateral wall 311 of handle 30, boss 361 of other end butt slide button 36, be equipped with the screw hole from set bar 38 one end, be fixed in slide button 36 on from set bar 38 through the screw that passes the screw hole, slide button 36 is

The other end of the self-locking bolt 38 corresponds to the self-locking hole on the self-locking pin 33, and one end of the push rod 35 which is a ball head is matched with the concave part 21 on the second connector 20.

Because the push rod 35 deflects to a certain extent under the action of the torsion spring 34 and is not vertically arranged, the handle 30 is pushed, the ball end of the push rod 35 slowly becomes vertical under the action of the concave portion 21 of the second joint 20, at this time, the push rod 35 is in a compressed state, so that the first joint 10 and the second joint 20 are locked, the sliding button 36 slides under the action of the return spring 37 to drive the self-locking bolt 38 to move until the other end of the self-locking bolt 38 is inserted into the self-locking hole on the self-locking pin 33, at this time, the self-locking pin 33 cannot rotate, because the end portion of the push rod 35 is arranged in the concave portion 21 of the second joint 20, the separation from the concave portion 21 cannot be achieved, the reliable self-locking effect is achieved, when the sliding button 36 is pushed to overcome the action of the return spring 37 to withdraw the other end of the self-locking bolt 38 from the self-locking hole on the self-locking pin, the first joint 10 and the second joint 20 are opened. The self-locking bolt is arranged in the handle, forms self-locking by matching with the self-locking pin, and has compact structure.

One end of the adjusting screw 23 is opposite to the handle 30, and when the adjusting screw 23 is rotated to enable the adjusting screw 23 to prop against the handle, the other end of the self-locking bolt 38 is inserted into the self-locking hole in the self-locking pin 33, so that self-locking is facilitated.

Example two

The utility model provides a auto-lock scray, includes first joint, second joint and handle 60, one side that first joint and one side that the second connects are connected through first articulated axle is articulated, the one end of handle 60 and the opposite side that the first joint passes through second articulated axle and articulates and is connected. The structure of this embodiment is different from the structure of the first embodiment in the structure of the handle mechanism and the components mounted on the handle.

Referring to fig. 2, a first side wall 61 and a second side wall 62 are disposed on the handle 60, a first hinge hole 611 and a limiting groove 612 are disposed on the first side wall 11, a second hinge hole 621 is disposed on the second side wall 62, a first partition 622 and a second partition 623 are disposed between the first side wall 61 and the second side wall 62, a first through hole is disposed on the first partition 622, and a second through hole is disposed on the second partition 623. The handle 60 is provided with a self-locking pin 63, a torsion spring 64, a top rod 65, a return spring 67, a self-locking bolt 68 and a sliding button 66, the self-locking pin 63 is arranged in a first hinge hole 611 and a second hinge hole 621, the self-locking pin 33 is provided with a connecting hole, the torsion spring 64 is sleeved on the self-locking pin 63, one end of the torsion spring 64 is abutted against the self-locking pin 63, the other end of the torsion spring is abutted against the second side wall 62 of the handle 60, the top rod 65 is arranged in the connecting hole, one end of the top rod 65 is a ball head, the other end of the top rod 65 is provided with a receiving hole 651, the receiving hole 651 is used for receiving one end of the self-locking bolt 68, the self-locking pin 63 deflects under the action of the torsion spring 64, so that the connecting hole is obliquely arranged, namely in a non-vertical direction, the, the extension part of the sliding button 66 is arranged in the limiting groove 612, the return spring 67 is arranged between the first partition 622 and the second partition 623, and the self-locking bolt 68 is "_I1The self-locking bolt 68 penetrates through the first through hole, the return spring 67 and the second through hole, the snap spring 70 is arranged on the self-locking bolt 68, one end of the return spring 67 abuts against the first partition 622, and the other end of the return spring abuts against the snap spring 70, so that the self-locking bolt 68 moves towards the self-locking pin 63 under the action of the return spring 67 and drives the sliding button 66 to move.

Because the push rod 65 has a certain deflection under the action of the torsion spring 64 and is not vertically arranged, the handle 60 is pushed, the ball end of the push rod 65 slowly becomes vertical under the action of the concave part of the second joint, at the moment, the push rod 65 is in a compression state, so that the first joint and the second joint are locked, the self-locking bolt 68 slides under the action of the return spring 67 until the other end of the self-locking bolt 68 is inserted into the receiving hole 651 in the ejector 65, at which time the self-locking pin 63 cannot rotate, because the end part of the mandril 65 is arranged in the concave part of the second joint and can not be separated from the concave part, the self-locking effect is achieved, when the slide button 66 is pushed to bring the self locking bolt 68 against the action of the return spring 67 to withdraw the other end of the self locking bolt 68 from the receiving hole 651 in the jack 65, the handle 60 is turned and the ram 65 deflects so that the ball end of the ram 65 disengages the recess, opening the first and second joints.

The self-locking bolt can also be provided with

In this configuration, the other end of the latching pin is aligned with the receiving hole of the plunger 65.
