Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

It should be noted that, if directional indications (such as upper, lower, left, right, front and rear … …) are involved in the embodiment of the present invention, the directional indications are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are changed accordingly.

The utility model provides a waterproof parallel groove clamp of integral type.

In this embodiment, referring to fig. 1 and 2, the integral waterproof parallel groove clamp includes an upper clamp plate 1, a lower clamp plate 2 and a bolt 3 for connecting the upper clamp plate 1 and the lower clamp plate 2, wherein two sides of the lower clamp plate 2 are provided with "C" shaped grooves 4, an embedding opening 5 for embedding the upper clamp plate 1 is arranged above the lower clamp plate 2, a protruding step 6 is arranged on the lower clamp plate 2 along the periphery of the embedding opening 5, two sides of the upper clamp plate 1 are provided with arc-shaped grooves 7 adapted to the "C" shaped grooves, a sealing step 8 extends outwards from the periphery of the upper clamp plate, the sealing step 8 is positioned right above the protruding step 6, a waterproof sealing ring 9 is embedded on the lower surface of the sealing step, when the upper clamp plate and the lower clamp plate are locked by the bolt, the protruding step abuts against and extrudes the waterproof sealing ring to realize sealing, thereby preventing liquid such as external rainwater from entering and corroding wires and clamps, the good conductivity between the wire and the wire clamp is ensured;

The upper clamping plate 1 and the lower clamping plate 2 are connected into a whole through the spiral spring 10, and the upper clamping plate and the lower clamping plate are connected into a whole through the spiral spring, so that the wire clamp is convenient to take and mount.

The lower surface of the sealing step is provided with a dovetail groove 11, and the waterproof sealing ring is provided with a dovetail connecting part 12 matched with the dovetail groove. The waterproof sealing ring is detachable and can be replaced independently after the waterproof sealing ring is worn.
