Description

Technical Field

[0001] The invention relates to the technical field of logistics and transportation, and in particular to a cargo safety transportation cabinet with a built-in fixing mechanism. Background Art

[0002] In logistics transportation, cargo securing is a key link to ensure that the cargo is delivered safely and intact to the destination. When the cargo is stacked in the container, it needs to be secured to prevent it from being stepped on and scattered during transportation.

[0003] In the prior art: the patent with authorization publication number CN202322751031.8 discloses a fully automatic universal transport fixing mechanism, including a base; a V-shaped support and a trapezoidal screw are installed on the end face of the base, a hollow slide rail is provided on the V-shaped support, and one end of the trapezoidal screw is connected to a support block; a proximity switch is provided on the support block, and the other end of the trapezoidal screw is connected to a control motor and a hand wheel in sequence; the transport fixing mechanism has some problems in actual operation, such as the need for manual drive to adjust each docking point to contact the cargo. If a certain point does not accurately fit the cargo, there will be safety hazards to the cargo. There is no good buffer section, and the support block is directly used to contact the cargo, resulting in a large pressure at the support point. When the cargo shakes, the force is concentrated at one point, which will damage the cargo. The carrying capacity is weak and the safety is low.

The motor 12 is running, and the output shaft of the motor 12 rotates, thereby driving the screw rod 32 to rotate, thereby driving the cross swivel 33 to move upward in the top fixed mounting frame 31, and then the distance between the two longitudinally adjacent middle fixed frames 36 and the distance between the two laterally adjacent middle fixed frames 36 are pulled through the transmission frame 35, so that they are relatively close to each other, and when the four middle fixed frames 36 are close to the middle of the sealed cabinet 1, the first telescopic rod 34 and the second telescopic rod 37 are driven to perform adaptive contraction movement.

It should be noted that the polyester container tensioner in this embodiment has a height limit, and the height limit is the distance between the floor 9 and the ceiling 7, so when stacking goods When the goods are transported into the transport cabinet, the height of the placed goods cannot exceed this height. After the goods are stacked, the side support plates 46 are respectively inserted into the left and right sides of the stacked goods. The two side support plates 46 clamp the stacked goods, and then regularly change the position of the four vertical rods 41. In this process, the four side sliding seats 491 on the upper side and the four on the lower side will be driven to gradually move away from each other, and then the first connecting rod 43 will be pulled in real time through the second connecting rod 492, so that the angle between the two first connecting rods 43 in the four fixed two-way rotating seats 42 will gradually increase, and then drive every two vertically adjacent middle transfer seats 44 to move away from each other, until the four top blocks 45 are inserted into the top connecting grooves 48 at the corresponding positions.

[0031] The cabinet further includes a rear support mechanism 8, which includes a rear sliding seat 81 and a third connecting rod 82.

The outer surfaces of the two third connecting rods 82 are symmetrically fixedly connected with rectangular contact plates, and a rear support plate 6 is placed on the front side of the four rectangular contact plates. Then the rear support plate 6 is placed to the rearmost side of the transport cabinet until the rear side of the rear support plate 6 is aligned with the four The contact surfaces of the rectangular contact plates are connected, and then the goods are stacked in sequence inside the sealed cabinet 1. At the same time, the two rear sliding seats 81 on the upper side and the two rear sliding seats 81 on the lower side will also move relatively away from each other. At this time, under the scissor support structure of the two third connecting rods 82, the two rear sliding seats 81 on the upper side will move to the uppermost side of the vertical rod 41, and the two rear sliding seats 81 on the lower side will move to the lowermost side of the vertical rod 41. At this time, the rear support plate 6 can be stably supported from the rear side with a triangular stable structure. At this time, the goods are fixed tightly from three directions: the rear side, the left side and the right side. The operator can operate the tensioner 10, pass the strap through the fixed point of the goods, and then tie it to the mooring point of the vertical rod 41, and then close the cabinet door 2. At this time, the transport cabinet can be transported.

[0032] The present invention provides a cargo safety transport cabinet with a built-in fixing mechanism, and its working principle is as follows:

[0033] When the cargo safety transport cabinet is needed, the cabinet door 2 can be opened, and then the rear support plate 6 is placed to the rear side of the transport cabinet until the rear side surface of the rear support plate 6 is in contact with the contact surface of the four rectangular contact plates, and then the cargo is stacked in sequence inside the sealed cabinet 1. It should be noted that the sealed cabinet 1 has a height limit, which is the distance between the floor 9 and the ceiling 7. Therefore, when the cargo is stacked in the transport cabinet, the height of the cargo cannot exceed this height. When the cargo is stacked, the side support plates 46 are respectively inserted into the left and right sides of the stacked cargo. The two side support plates 46 clamp the stacked goods, and the control switch 11 can be adjusted and controlled. The motor 12 is running, and the output shaft of the motor 12 rotates, thereby driving the screw rod 32 to rotate, and then driving the cross swivel 33 to move upward in the top fixed mounting frame 31, and then the distance between the two longitudinally adjacent middle fixed frames 36 and the distance between the two transversely adjacent middle fixed frames 36 are pulled by the transmission frame 35, so that they are relatively close to each other. When the four middle fixed frames 36 are close to the middle of the sealed cabinet 1, the first telescopic rod 34 and the second telescopic rod 37 are driven to do adaptive The contraction movement will regularly change the position between the four vertical rods 41. In this process, the four side sliding seats 491 on the upper side will be driven to gradually move away from the four on the lower side, and then the first connecting rod 43 will be pulled in real time by the second connecting rod 492, so that the angle between the two first connecting rods 43 in the four fixed two-way rotating seats 42 will gradually increase, thereby driving every two vertically adjacent middle transfer seats 44 to move away from each other, until the four top blocks 45 are inserted into the top connecting grooves 48 at the corresponding positions, and at the same time, the two rear sliding seats 81 on the upper side and the two rear sliding seats on the lower side move away from each other. 81 will also do a relatively far-away operation. At this time, under the scissor-bracing structure of the two third connecting rods 82, the two rear sliding seats 81 on the upper side will move to the uppermost side of the vertical rod 41, and the two rear sliding seats 81 on the lower side will move to the lowermost side of the vertical rod 41. At this time, the rear support plate 6 can be stably supported from the rear side with a triangular stable structure. At this time, the goods are fixed tightly from the rear, left and right directions. The operator can operate the tensioner 10, pass the strap through the fixed point of the goods, and then tie it to the mooring point of the vertical rod 41, and then close the cabinet door 2. At this time, the transport cabinet can be transported.
