DETAILED DESCRIPTION

[0024] The technical scheme in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0025] Embodiment one, by Figures 1-3 Be provided, this embodiment relates to a kind of electric cable bridge of quick clamping type installation, including main bridge 1 and vice cover plate 2, and main bridge 1 is clamped and fixed between vice cover plate 2 by multiple groups of clamping mechanism, and clamping mechanism includes upper clamping piece and lower clamping piece, wherein upper clamping piece is set on vice cover plate 2, and lower clamping piece is set on main bridge 1;Upper clamping piece includes mounting plate 3, knob 4, rotating shaft 5 and eccentric column 6, wherein mounting plate 3 is fixedly arranged on vice cover plate 2, knob 4 and eccentric column 6 are all fixedly arranged on rotating shaft 5, shaft hole 7 is opened in mounting plate 3, and rotating shaft 5 is rotationally arranged in shaft hole 7;Lower clamping piece includes support 8, and support 8 is fixedly arranged on main bridge 1, and support 8 is internally provided with interconnected inner hole 9 and round hole 10, and the radius of inner hole 9 is greater than the radius of round hole 10;The axis of rotating shaft 5 is arranged eccentrically relative to the axis of inner hole 9;

[0026] In this way, in use, vice cover plate 2 is covered on the top of main bridge 1, eccentric column 6 on mounting plate 3 is placed in the inside of inner hole 9 after passing through round hole 10 on support 8, then knob 4 is rotated, knob 4 drives eccentric column 6 to rotate through rotating shaft 5, so that eccentric column 6 is clamped in the inside of inner hole 9 after eccentric rotation, and the position of eccentric column 6 after rotation is kept unmoved by the friction between eccentric column 6 and inner hole 9, so that the clamping process between vice cover plate 2 and main bridge 1 is quickly realized, and installation is more convenient.

[0027] Further, in order to further improve the stability of eccentric column 6 after rotation, integrated stop block 11 is fixedly arranged on rotating shaft 5, and stop block 11 is located between knob 4 and mounting plate 3;Stop block 11 is square in shape, and spring leaf 16 is fixedly arranged on mounting plate 3 in symmetry, two spring leaves 16 are respectively attached to the two sides of stop block 11, and integrated protrusion is formed on the side of spring leaf 16 close to stop block 11.

[0028] Thus, when the rotating shaft 5 does not rotate, the baffle 11 is limited by the spring leaf 16 on both sides, so as to improve the stability of the eccentric column 6; when the rotating shaft 5 needs to rotate, the knob 4 needs to be rotated with a certain force, so that the baffle 11 overcomes the elastic force of the spring leaf 16, and after rotation, such as ninety degrees, the spring leaf 16 will limit the baffle 11 again, so as to ensure the position accuracy of the eccentric column 6 on the rotating shaft 5 after rotation.

[0029] Specifically, the eccentric column 6 is clamped and matched with the inner hole 9 after rotating through the circular hole 10, wherein the cross-sectional area of the eccentric column 6 is equal to the cross-sectional area of the circular hole 10, and the cross-sectional area of the eccentric column 6 is smaller than the cross-sectional area of the inner hole 9.

[0030] Specifically, the end of the eccentric column 6 away from the knob 4 is formed into a tapered surface 12; thus, the eccentric column 6 is more easily inserted into the circular hole 10 through the tapered surface 12.

[0031] Specifically, the clamping mechanism is provided with four groups, and the four groups of clamping mechanisms are distributed at the four corners of the main bridge 1.

[0032] In the second embodiment, the cable bridge is installed by clamping. Figures 4-5 In the second embodiment, the cable bridge is installed by clamping.

[0033] Thus, in use, the limiting block 15 can be first turned over after passing through the heat dissipation hole 13, so that the connecting rod 14 on the limiting block 15 moves upward in the heat dissipation hole 13, so that the circular hole 10 on the support 8 moves upward to be clamped with the eccentric column 6 above it, so that professional workers do not need to weld the support 8 on the main bridge 1 in advance, and ordinary workers can also realize the installation process of the support 8, which is more convenient.
