A quick buckle joint

technical field

The present invention relates to a joint, in particular to a quick fastening joint.

Background technique

The present invention is based on the SF6 gas test of SF6 equipment with 604 type male joints. At present, the test work is carried out on SF6 gas equipment, and the SF6 gas test is carried out by tightening the screws. The 604 type male joints have external screw threads and internal There is a check valve to prevent the leakage of SF6 gas. The 604-type female connector has an internal thread and a thimble inside. When working, the 604-type female connector is tightened to drive the thimble to open the 604-type male connector check valve, so that the gas can be released. Flow along the 604-style female coupling tubing to the test instrument end. Because there are many SF6 gas equipment, the test joint must be disassembled and tightened many times during the test, which is time-consuming and labor-intensive when tightening the screws, which limits the operating efficiency of the test work.

Contents of the invention

In order to solve the above-mentioned technical defects, the present invention develops a quick fastening joint, which can ensure the tight connection between the air intake joint and the equipment air chamber interface only by pressing the operating handle, avoiding the work of screw tightening, assembly and disassembly, thereby reducing the test cost. Workload, effectively optimize the test process.

The technical solution of the present invention is: a fast fastening joint, including a bottom plate, a positioning handle is provided at one end of the bottom plate, a vertical plate is provided at the other end of the bottom plate, and a card slot is provided on the vertical plate, the An operating handle is provided on the base plate, and a 604-type female joint is provided on the operating handle.

Further, the operating handle includes a handle and a U-shaped frame. The handle is arranged at the bottom of the U-shaped frame. into the frame and fastened with bolts.

Further, the locking mechanism includes a pull button and a limit post, the bottoms on both sides of the base plate are provided with extension plates, the top ends on both sides of the opening of the U-shaped frame are connected to the extension plates by bolts, and the pull buttons are fixed by bolts At the bottom of the bottom plate between the two extension plates, one end of the toggle is connected to the limit column, and a through hole is provided on the extension plate on one side, and the toggle is pulled by hand when locking , make the limit post pass through the through hole of the extension plate to limit the limit boss of the operating handle.

Wherein, the positioning handle at one end of the bottom plate and the toggle do not affect each other, and the toggle is misplaced under the positioning handle, and will not be affected when the toggle is pulled.

When working, the operator holds the positioning handle with one hand to align the card slot on the vertical plate with the 604-type male connector on the SF6 equipment end, and the other hand pushes the operating handle to make it rotate, and the operating handle drives the 604-type female connector After passing through the card slot, connect with the 604-type male connector on the SF6 equipment end and press it, and then pull the pull button, so that the limit column passes through the perforation of the extension plate to limit the limit boss of the operating handle, and keep the pressed state. Finish charging and taking air. After the completion, the pull button can be pulled again, so that the limit post no longer limits the limit boss, the compression state is released, and the operation handle is pulled back for the next use.

The purpose of the present invention is to address the shortcomings of the way of tightening the screws in the gas test of SF6 equipment with 604-type male joints, but it is not limited to this, and it is also applicable to other applications such as charging and taking gas of SF6 equipment with 604-type male joints .

At the same time, the 604-type joint can also be replaced by other types of joints. Since the same type of SF6 gas equipment has the same interface and the SF6 gas test process is consistent, the quick fastening joint developed in this project can be used on the same type of equipment joints. Universal, with good promotion.

The beneficial effect of the present invention is that the user can ensure the tight connection between the quick fastening joint and the 604-type male joint by pressing the operating handle, thereby avoiding the assembly and disassembly work of tightening screws, thereby improving work efficiency and effectively optimizing the test process.
