Example Embodiment

[0011] The present invention will be described in detail below in conjunction with specific embodiments.

[0012] As shown in the drawings, a box quick connection device of the present invention includes locking sleeves 1 fixed in the grooves at the four corners of the bottom of the upper box 10 and the tops of the lower box 12 respectively. There are four locking structures at the four corners of the wall. On the side wall of each locking sleeve 1, four locking taper grooves 7 are equally spaced along the same circumferential direction. Each of the locking structures It includes a locking base 9 for fixing on the top wall of the lower box 12, and an inner sleeve is fixed on the locking base 9. When the locking sleeve 1 is connected to the locking structure, the inner sleeve The cylinder is inserted into the locking sleeve 1 and the bottom wall of the locking sleeve 1 is supported on the locking base 9. The middle of the locking base is rotatably connected with a vertical transmi...

Abstract

The invention discloses a quick connecting device for boxes. The quick connecting device comprises locking sleeves and four locking structures, wherein the locking sleeves are used for being fixed into grooves in the four corners of the bottom of the upper box, and the four locking structures are fixed to the four corners of the top wall of the lower box correspondingly. Four locking cone grooves are formed in the side wall of each locking sleeve in the same circumferential direction at equal intervals. Each locking structure comprises a locking base which is used for being fixed to the top wall of the lower box. Inner sleeves are fixed to the locking bases. The middle of each locking base is connected with a transmission cone in a threaded mode through a transmission shaft. Four triangular structures are symmetrically arranged on each transmission cone. A guide column which is fixed to the corresponding locking base is mounted between every two adjacent triangular structures. A locking arm is fixed between the upper portions of every two adjacent guide columns through a rotary shaft. Locking cone heads on the outer sides of the lower portions of the locking arms are matched with the locking cone grooves in shape. According to the quick connecting device for the boxes, the locked surfaces are tightly connected, and locking is safe and reliable.

Description

technical field [0001] The invention relates to a quick connection device for boxes, in particular to a quick connection device for heavy-duty boxes. Background technique [0002] At present, the common box connection is the connection device between the containers. The advantage of this device is that it is convenient to connect. However, when the box is heavier or larger than the container, the reliability of this connection method will decrease, and there is a gap between the boxes after this device is connected, which is easy to cause the gap between the boxes in harsh environments. Relative movement, especially in the case of several layers superimposed, will cause the cabinet to fall, and the consequences will be more serious if there are people living in the cabinet. Contents of the invention [0003] The object of the present invention is to overcome the disadvantages of the prior art, and provide a fast connection device for a box with tight connection between lo...
