Preferably, the fixture blocks are symmetrically arranged on two sides of the fixing column, and the fixture blocks and the sliding grooves are not on the same plane.

Preferably, the upper surface of the fixture block is a smooth inclined curved surface, and the lower surface of the fixture block is a horizontal plane.

Preferably, the fixture block body is arranged in the placing groove, the placing groove is formed inwards along the surface of the fixing column, and the fixture block can rotate along the fixing shaft and is completely contained in the placing groove.

Preferably, the top of the fixed column is provided with an internal thread, and the round cover is fixed to the top of the fixed column through the engagement of a screw and the internal thread.

Compared with the prior art, the utility model discloses clamping part fixes on the fixed column about the parallel groove clamp, goes up the clamping part and can slide, and ascending holding power and the decurrent fixing of fixture block that provides through the external ear on the fixed column to make and go up the clamping part fixed, the fixture block can extrude simultaneously, thereby realized going up the clamping part and realizing quick fixed, avoid using the fixed inconvenient of bringing of bolt and nut, reduce the danger that high altitude construction brought.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

As shown in figure 1, the copper-aluminum parallel groove wire clamp comprises an aluminum upper clamping part 2 and an aluminum lower clamping part 1, wherein a copper wire groove 4 and an aluminum wire groove 3 are respectively arranged at the upper two ends of the clamping part, an insulating cushion block is arranged between the copper wire groove 4 and the aluminum clamping part, the insulating cushion block is connected with the aluminum clamping part and the copper wire groove 4 through gluing (not shown in the figure), the lower clamping part 1 is fixed at the tail part of a fixed column 5, the upper clamping part 2 is arranged on the fixed column 5 in a penetrating way and moves up and down, the fixed column 5 is hollow, a sliding groove 9 is arranged on the surface, a circular baffle 11 is arranged in the fixed column 5, the circular baffle 11 is provided with a pair of symmetrical outer lugs 10, the outer lugs 10 extend to the outer surface of the fixed column 5 through the sliding groove 9, an expansion spring 12 is arranged below the baffle 11, the outer lugs 10 abut against the upper clamping part 2, a, the latch 8 is rotatable around a fixed shaft 14, and a knob spring is provided on the fixed shaft 14, the knob spring providing an elastic force toward the outside of the fixed column 5.

Wherein 5 surfaces of fixed column that fixture block 8 set up standing groove 13, fixture block 8 can rotate to standing groove 13 in along fixed axle 14, and can put into standing groove 13 completely, do not influence passing through of last clamping part 2, wherein, fixture block 8 is not on the coplanar with spout 9, for the convenience of extrusion, the upper surface of fixture block 8 is slant decurrent curved surface, the lower surface is the horizontal plane, fixture block 8 lower surface supports the upper surface of last clamping part 2, wherein, the auricle 10 of baffle 11 supports the lower surface of last clamping part 2, therefore, it just is fixed between fixture block 8 and auricle 10 to go up clamping part 2, auricle 10 only provides upward pressure, make it hug closely fixture block 8 to go up clamping part 2, be difficult not hard up, the design like this, it can easily fix on fixed column 5 to go up clamping part 2, reduce the dead time, it is more high-.
