Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

Example

As shown in the figure, a device for fixing the drain connecting plate and installing the drain connecting plate bolts includes a main body 1 and a fastening head 3. The main body 1 is composed of the vertical surfaces on both sides and the bottom surface in the middle to form the word "concave". type, the elevation of one side of the main body is provided with a groove 8 and a card groove 6, and the groove 8 and the card groove 6 are arranged side by side; the upper part of the cavity of the groove 8 is a regular hexagon, and the lower part of the cavity is The size of the upper cavity of the rectangle and regular hexagon matches the size of the bolt head of the drainage connecting plate, and the size of the lower cavity of the rectangle matches the bolt shank on the bolt head of the drainage connecting plate. Described draw-in groove 6 is rectangular, and the height of rectangular draw-in groove 6 matches with the overall height of groove 8, and the width of rectangular draw-in groove 6 matches with the top opening of groove 8 upper mold cavity, and the back panel of draw-in groove is a stopper. The plate 7 and the baffle 7 are integrated with the main body 1 . The distance between the bottom end of the groove 8 and the bottom surface of the main body 1 should ensure that after the bolt head of the drainage connecting plate falls into the slot 6, the bolt shank on the bolt head of the drainage connecting plate matches the bolt hole on the drainage connecting plate .

The other side elevation of the main body 1 is provided with a threaded bolt hole 5, the fastening head pushes the screw 2 through the bolt hole 5, and one end of the fastening head pushes the screw 2 to connect with the fastening head 3, and the fastening head advances The other end of the screw rod 2 is connected to the universal torx head 4, and the universal torx head is connected to the insulating operating rod; the fastening head pushes the screw in and out through the internal thread of the bolt hole so as to realize the movement of the fastening head on the bottom surface of the main body 1.

When the operator needs to connect the drainage connecting plate, first use an insulating tool to butt the two drainage connecting plates on the bottom surface of the main body, and place the bolt head of the drainage connecting plate and the bolt rod on the bolt head longitudinally with the upper part of the groove 8 respectively. The chamber corresponds to the lower chamber, push the bolt head of the drainage connection plate, the bolt head of the drainage connection plate and the bolt rod on the bolt head change from vertical to horizontal, so that the bolt head of the drainage connection plate falls into the slot 6 behind the groove 8, and the bolt head The bolt shank on the head stretches out the groove 8 lower die cavities.

Since the bolt shank on the bolt head of the drainage connecting plate is placed horizontally and matches the bolt hole on the drainage connecting plate, the bolt shank on the bolt head of the drainage connecting plate can pass through the drainage connecting plate, and the bolt on the bolt head of the drainage connecting plate After the rod passes through the drainage connecting plate, the operator manually rotates the insulating operating rod to drive the fastening head to advance the screw to rotate, and pushes the fastening head forward until the drainage connecting plate is fastened. The fastening head can be loosened from the drainage connecting plate by manually rotating the insulating operating lever in reverse. This device can avoid the phenomenon of arcing caused by improper connection operation during the connection process of the drainage connecting plate, and further improves the safety factor of live work.
