Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
FIG. 2 is a separation diagram of the present utility model;
fig. 3 is a use diagram of the present utility model.
In the figure: the device comprises a lower clamping piece 1-, an upper clamping groove 11-, an upper clamping piece 2-, a lower clamping groove 21-, a first fixing part 22-a second fixing part 23-a lifting column 3-a partition board 4-and a side plate 5-respectively.
Detailed Description
A connection fixture according to the present utility model will be further described with reference to the accompanying drawings.
As shown in fig. 1-2, a connecting and fixing piece comprises one or two lower clamping pieces 1 and two upper clamping pieces 2 matched with the lower clamping pieces 1, wherein the two upper clamping pieces 2 are respectively vertically clamped and matched with two ends of the clamping pieces 1, and fixing parts matched and fixed with other accessories are arranged on the upper clamping pieces 2. The upper clamping piece 2 is matched with the upper clamping groove 11 to form two lower clamping grooves 21 with downward openings, the lower clamping grooves 21 are matched with the upper clamping grooves 11 in a clamping manner, and for installation convenience, the upper clamping grooves 11 and the lower clamping grooves 21 are all formed into wedge-shaped bayonets with large slot opening distances and small slot bottom opening distances. The upper clip 2 and the lower clip 1 are preferably metal steel plates of about 5 mm.
The fixing part comprises a first fixing part 22 and a second fixing part 23 which are arranged on the upper clamping piece 2, and the directions of the first fixing part 22 and the second fixing part 23 are mutually perpendicular. The first fixing part 22 is arranged at one end of the upper clamping piece 2, which is matched with the lower clamping piece 1 in the width direction, and extends outwards, and is used for locking and fixing the upper clamping piece 2 and the lower clamping piece 1 on other accessories; the second fixing part 23 is arranged at one end of the upper clamping piece 2, which is far away from the lower clamping piece 1, in an outward extending way in the length direction and is used for fixing the upper clamping piece 2 on another accessory; the first fixing portion 22 and the second fixing portion 23 are each provided with a waist-shaped hole, and are fastened with the fitting by a mating screw or bolt.
