Detailed Description

The utility model will be further described with reference to examples of embodiments shown in the drawings to which the utility model is attached.

As shown in fig. 1 and 2, which are schematic structural diagrams of the present invention, it is usually fixed on one side of a manual cart for clamping irregular or large-sized articles, and includes a supporting plate 1, a first vertical plate 2, an upper fixing plate 3, a lower fixing plate 4, a fixing column 5, a second vertical plate 6, a rotating column 7, a power mechanism 8, a through hole 9, a fixed clamping arm 10, a movable clamping arm 11, a carriage 12, a fixed clamping jaw 13, a pivot block 14, a push rod cylinder 15, and a movable clamping jaw 16.

Wherein, backup pad 1 is rectangular form metal sheet, fixes on manual shallow through the mode of screw fastening. The two fixing columns 5 are arranged at two ends of the supporting plate 1 in a penetrating way. The top fixed plate 3 is fixed at the top of fixed column 5, and the bottom fixed plate 4 is fixed at the bottom of fixed column 5 (fixed between fixed column 5 and top fixed plate 3 and bottom fixed plate 4 is realized through the mode of screw fastening). First riser 2 is fixed between backup pad 1 and upper fixed plate 3, and second riser 6 is fixed between backup pad 1 and bottom plate 4 (first riser 2 and second riser 6 are used for improving the joint strength between upper fixed plate 3, bottom plate 4 and the backup pad 1). Through-hole 9 is seted up at upper fixed plate 3, backup pad 1 and bottom plate 4 both ends, and column spinner 7 rotates and installs at the both ends of backup pad 1 (two fixed columns 5 are in between two column spinner 7, and column spinner 7 passes through-hole 9, and the diameter of through-hole 9 is greater than the diameter of column spinner 7).

The rotary column 7 is driven by the power mechanism 8 to rotate, as shown in fig. 1, the power mechanism 8 includes a pushing cylinder 81, a pushing plate 82, a connecting plate 83, a connecting rod 84 and a holding block 85. The cylinder body of push cylinder 81 is fixed on second riser 6, and push pedal 82 is connected on the guide bar of push cylinder 81. The connecting plates 83 are pivotally connected to both ends of the push plate 82 (the top and bottom of either end of the push plate 82 are pivotally connected to the connecting plates 83). The connecting rod 84 is pivotally connected between the two connecting plates 83, and the holding block 85 is pivotally connected to an end of the connecting rod 84 away from the connecting plates 83 (the push plate 82, the connecting plates 83 and the connecting rod 84 can horizontally rotate relatively, and the connecting rod 84 and the holding block 85 can vertically rotate relatively). The bottom of the rotary column 7 is fixed on the holding block 85 (the pushing cylinder 81 pushes the pushing plate 82 to move forward, and since the pushing plate 82 is pivotally connected with the connecting plate 83 and the connecting rod 84 is pivotally connected with the connecting plate 83, the connecting rod 84 can rotate a certain angle relatively, and then the holding block 85 and the rotary column 7 are driven to rotate).

Two fixed clamping arms 10 are fixed at the top of one rotary column 7 at intervals, two movable clamping arms 11 are fixed at the top of the other rotary column 7 at intervals (the two fixed clamping arms 10 and the movable clamping arms 11 are both positioned between the support plate 1 and the upper fixing plate 3). The carriage 12 is fixed between the two movable clamping arms 11 and the two fixed clamping arms 10. The stationary jaw 13 is fixed to the end of the stationary gripping arm 10. The pivot block 14 is pivotally connected to the ends of the two movable clamping arms 11, and the movable clamping jaw 16 is fixed on the pivot block 14 and is used in cooperation with the fixed clamping jaw 13 to clamp a required product together. The cylinder body of the push rod cylinder 15 is fixed on the upper fixing plate 3, and the piston rod of the push rod cylinder 15 is connected to the movable clamping jaw 16 (when the push rod cylinder 15 pushes the movable clamping jaw 16, the movable clamping jaw 16 rotates within a certain angle because the movable clamping jaw 16 is fixed with the pivot block 14).
