Detailed Description

In order to make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are clearly and completely described with reference to the drawings in the embodiments of the present invention, and obviously, the embodiments described below 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.

As shown in fig. 1 and 2, the utility model provides a phase sequence identification means for cable distribution box, including phase sequence tablet 1 and plate-shaped clamp 2 fixed mounting has arc clamp 3 on the phase sequence tablet 1, the both ends of arc clamp 3 all are connected with the adjusting rod body 4, and be equipped with a plurality of annular teeth 5 on the adjusting rod body 4, the tip of plate-shaped clamp 2 is in through the 6 centre grippings of a set of just relative C clamp that sets up 6 on the adjusting rod body 4, just be equipped with on the C clamp 6 and be used for the interlock the screens recess 7 of annular teeth 5.

The C-shaped clamping pieces 6 are arranged at the end parts of the plate-shaped clamping bodies 2, the C-shaped clamping pieces 6 are clamped on the adjusting rod bodies 4, two ends of the plate-shaped clamping bodies 2 connected with the C-shaped clamping pieces 6 are arranged on the adjusting rod bodies 4, sealing areas are formed by the plate-shaped clamping bodies 2, the arc-shaped clamping bodies 3 and the adjusting rod bodies 4, and the sealing areas can be reduced by pushing the plate-shaped clamping bodies 2 to the adjusting rod bodies 4.

In this embodiment, in the initial state, the plate-shaped clamp 2 and the adjusting rod 4 are in the separated state, the cable is placed between the group of adjusting rods 4, and the plate-shaped clamp 2 is installed on the adjusting rod 4, so that a closed area is formed, the cable is located in the closed area, the closed area is gradually reduced by pushing the plate-shaped clamp 2 leftwards, and the cable is clamped from the left side and the right side, so that the phase sequence cards 1 are fixedly installed on the cable.

When taking out, the plate-shaped clamp body 2 can be taken down from the adjusting rod body 4 only by pushing the plate-shaped clamp body 2 to the right side; the whole operation process can be completed by only pushing and pulling two actions, and the operation is simple and the use is convenient.

The principle that the C-shaped clamping sheet 6 clamps the adjusting rod body 4 mainly comprises the following steps: the C-shaped clamping pieces 6 are arranged on the end faces of the plate-shaped clamping bodies 2 in a positive opposite mode, the distance between the two C-shaped clamping pieces 6 is slightly smaller than the diameter of the adjusting rod body 4, and the C-shaped clamping pieces 6 are elastic, so that when the adjusting rod body 4 is manually inserted between the two C-shaped clamping pieces 6, the C-shaped clamping pieces 6 are extruded to enable the C-shaped clamping pieces 6 to be clung to the adjusting rod body 4, the clamping grooves 7 in the C-shaped clamping pieces 6 are embedded in the annular teeth 5, the C-shaped clamping pieces 6 are prevented from easily sliding on the adjusting rod body 4, and the C-shaped clamping pieces 6 are stably fixed on the adjusting rod body 4 under the effect of no.

Because the C-shaped clamping piece 6 has elasticity, when the plate-shaped clamping body 2 is manually pushed, the annular tooth 5 can extrude the clamping groove 7, so that the C-shaped clamping piece 6 moves towards two sides, and the C-shaped clamping piece 6 slides on the adjusting rod body 4 until the clamping groove 7 is nested in the next annular tooth 5.

As shown in fig. 2, the end of the C-shaped clip 6 is connected to one side of the plate-shaped clip body 2 through a pressing piece 8, the C-shaped clip 6 and the pressing piece 8 form a triangular cavity 9 on the end surface of the plate-shaped clip body 2, and the included angle between the pressing piece 8 and the end surface of the plate-shaped clip body 2 is an acute angle.

Although the C-shaped clip 6 has elasticity, the C-shaped clip 6 is easily lost or damaged by squeezing and restoring the C-shaped clip 6 for a long time, so that the pressing piece 8 is arranged on the outer side of the C-shaped clip 6, the C-shaped clip 6 is squeezed towards the inner side by the elastic pressing piece 8, the C-shaped clip 6 is more tightly attached to the adjusting rod body 4, the plate-shaped clip body 2 is more stably installed, the stress of the C-shaped clip 6 is shared by the pressing piece 8, and the service life of the C-shaped clip 6 is prolonged.

The triangular cavity 9 formed by the C-shaped clamping piece 6, the pressing piece 8 and the plate-shaped clamping body 2 has the function of providing a reserved space for deformation of the C-shaped clamping piece 6, and the triangular cavity 9 enables the three to form a stable triangular support, so that the stable triangular support is beneficial to stably supporting the C-shaped clamping piece 6.

The C-shaped clip 6 is connected to the pressing plate 8 by a connecting body 11, and the connecting body 11 has a ring-shaped structure having a plurality of blades.

When the special-shaped connector 11 can be installed in the triangular cavity 9, the blade part of the special-shaped connector 11 is connected with the C-shaped clamping piece 6, the pressure applying piece 8 and the plate-shaped clamp body 2, the blade part is connected with the blade part through the ring-shaped connector 11, the stress of the blade part can be dispersed, and the blade part can be connected with the three part, so that the three part can be quickly deformed and restored, rod-shaped tools such as a screwdriver and the like can be inserted into the ring-shaped part, and the plate-shaped clamp body 2 can be quickly detached from the adjusting rod body 4 by applying force to the screwdriver.

As shown in fig. 3, the cross section of the annular tooth 5 is in an isosceles trapezoid shape.

Compare in traditional cross-section for triangular tooth structure, this kind of cross-section is isosceles trapezoid shape's tooth structure, has the inclined plane that length is shorter, because when carrying out relative slip between screens recess 7, C shape clamping piece 6 two, the inclined plane is both extrudees the region each other, sets up the inclined plane that length is shorter and can reduce both relative slip's the degree of difficulty. And, the end of the adjusting rod body 4 is provided with a conical body 10. The volume of the tail end of the adjusting rod body 4 is reduced through the conical body 10, and the conical structure is easier to insert between the two C-shaped clamping sheets 6, so that the installation difficulty is reduced.
