Description

Technical Field

[0001] The utility model relates to the technical field of cold chain logistics tracking, in particular to a cold chain logistics tracking device. Background Art

[0002] With the continuous development of society and the continuous advancement of science and technology, the technologies related to cold chain logistics tracking are also constantly improving. Cold chain logistics can ensure that refrigerated and frozen foods are always kept in a specified low-temperature environment during production, storage, transportation, sales, and each link before consumption to ensure food quality.

[0003] The cold chain logistics tracking device currently used clamps two clamp arms on the goods through a return spring, but there is no structure to limit the clamp arms. When the clamp arms are hit by external force, the distance between the two clamp arms tends to increase, causing the clamp arms to separate from the goods, and the positioning device on the clamp arms will also separate from the goods, resulting in poor tracking effect on cold chain logistics. Utility Model Content

[0004] The purpose of the utility model is to solve the following shortcomings in the prior art: the cold chain logistics tracking device currently used clamps two clamp arms on the goods through a return spring, but there is no structure to limit the clamp arms. When the clamp arms are collided by external force, the distance between the two clamp arms is likely to increase, thereby causing the clamp arms to separate from the goods, and the positioning device on the clamp arms will also separate from the goods, resulting in poor tracking effect on the cold chain logistics, and a cold chain logistics tracking device is proposed.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A cold chain logistics tracking device comprises a first clamp arm, a second clamp arm and a positioning device, wherein two fixing columns and a fixing block are fixedly mounted on the first clamp arm, a limiting plate and two sliding rods are fixedly mounted on the second clamp arm, and the two sliding rods are respectively connected by two first springs and two fixing columns;

[0007] A round rod is rotatably mounted on the fixed block, a cam is fixedly connected to the round rod, a rectangular rod is slidably connected to the round rod, a limiting assembly is provided on the rectangular rod, the limiting assembly includes a plurality of clamping blocks fixedly mounted on one end of the rectangular rod, a plurality of clamping slots are provided on the limiting plate, and each of the clamping blocks is clamped with the corresponding clamping slot.

[0008] Preferably, a second spring is sleeved on the rectangular rod, one end of the second spring is fixedly connected to the rectangular rod, and the other end of the second spring is fixedly connected to the round rod.

[0009] Preferably, one end of the rectangular rod away from the limiting plate is fixedly connected to a rotating wheel, and the first clamping arm is provided with an opening for horizontal movement of the rotating wheel.

[0010] Preferably, a transparent glass plate is fixedly connected to the second clamping arm, and an adhesive groove is provided on the transparent glass plate.

[0011] Preferably, a clamping block is fixedly connected to the first clamping arm and the second clamping arm, and each clamping block is provided with a plurality of clamping teeth.

[0012] Preferably, a positioning frame is fixedly connected to the first clamping arm, and the positioning frame is connected to the positioning device via two bolts.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] After the teeth of the two clamping blocks clamp the goods, the pulling force applied to the rotating wheel is removed. Under the elastic force of the second spring, the rectangular rod and the round rod will slide relative to each other until each clamping block is respectively engaged with the corresponding clamping slot, thereby preventing the limit plate from moving, and the distance between the first clamping arm and the second clamping arm cannot change. When the clamping arm is collided by external force, the distance between the first clamping arm and the second clamping arm will not increase, thereby effectively preventing the clamping arm from separating from the goods, and the positioning device on the first clamping arm will not separate from the goods, which has a better tracking effect on cold chain logistics.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0022] Reference Figure 1-Figure 4 A cold chain logistics tracking device comprises a first clamping arm 1, a second clamping arm 11 and a positioning device 7 (the positioning device 7 has been disclosed in the patent document with publication number CN211002693U, and its working principle is not described in detail). Two fixed columns 3 and a fixed block 4 are fixedly installed on the first clamping arm 1, a limiting plate 16 and two sliding rods 15 are fixedly installed on the second clamping arm 11, and the two sliding rods 15 are respectively connected to the two fixed columns 3 through two first springs 10. A round rod 12 is rotatably installed on the fixed block 4, a cam 9 is fixedly connected to the round rod 12, and a rectangular rod 5 is slidably connected to the round rod 12. A limiting assembly is arranged on the rectangular rod 5, and the limiting assembly comprises a plurality of clamping blocks 17 fixedly installed at one end of the rectangular rod 5, and a plurality of clamping slots 18 are provided on the limiting plate 16, and each clamping block 17 is clamped with a corresponding clamping slot 18.

[0023] A second spring is sleeved on the rectangular rod 5, one end of the second spring is fixedly connected to the rectangular rod 5, and the other end of the second spring is fixedly connected to the round rod 12. The end of the rectangular rod 5 away from the limiting plate 16 is fixedly connected to the rotating wheel 2. The first clamping arm 1 is provided with an opening for the horizontal movement of the rotating wheel 2. When the rotating wheel 2 is pulled and the rotating wheel 2 moves inside the opening, the rectangular rod 5 will slide relative to the round rod 12, and the second spring will be deformed. When the rectangular rod 5 and the round rod 12 are in contact, the friction force is relatively large, which can effectively prevent the rectangular rod 5 and the rotating wheel 2 from moving at will.

[0024] A transparent glass plate 14 is fixedly connected to the second clamping arm 11, and an adhesive groove is provided on the transparent glass plate 14. A barcode or a QR code containing relevant information of the goods can be pasted in the adhesive groove. The positioning device 7 can locate the position of the goods. A clamping block 13 is fixedly connected to the first clamping arm 1 and the second clamping arm 11. Each clamping block 13 is provided with a plurality of clamping teeth. When the clamping teeth of the two clamping blocks 13 clamp the goods, the surface of the clamping teeth is rough, and the friction between the clamping teeth and the goods is large, which can effectively prevent the clamping teeth from detaching from the goods. A positioning frame 6 is fixedly connected to the first clamping arm 1, and the positioning frame 6 is connected to the positioning device 7 by two bolts 8. One end of each bolt 8 passes through the positioning frame 6 and is threadedly connected to the outer shell of the positioning device 7, so that the positioning device 7 and the positioning frame 6 can be firmly connected together.

[0025] When the cam 9 is in use, the rotating wheel 2 is first pulled. During the movement of the rotating wheel 2 inside the opening, the rectangular rod 5 and the round rod 12 will slide relative to each other. In the initial state, each block 17 is engaged with the corresponding slot 18. After the multiple blocks 17 move together with the rectangular rod 5, they will disengage from each slot 18, and then the rotating wheel 2 will rotate. The cross section of the connection between the rectangular rod 5 and the round rod 12 is rectangular. Under the transmission action of the rectangular rod 5, the round rod 12 rotates at the same time. During the relative rotation of the round rod 12 and the fixed block 4, the cam 9 will rotate together. During the rotation of one end of the cam 9, it will move against the surface of the second clamping arm 11, thereby pushing the second clamping arm 11 to move, and the distance between the second clamping arm 11 and the first clamping arm 1 increases. Each sliding rod 15 slides relative to the corresponding fixed column 3 respectively. Since one end of each first spring 10 is fixedly connected to the fixed column 3 and the other end is fixedly connected to the sliding rod 15, the first spring 10 is deformed.

[0026] After that, the first clamp arm 1 and the second clamp arm 11 are placed at specific positions, and the first clamp arm 1 and the second clamp arm 11 are respectively located on both sides of the goods, and then the rotational force applied to the rotating wheel 2 is applied. Under the elastic force of the first spring 10, the second clamp arm 11 will move towards the direction close to the first clamp arm 1 until the clamping teeth of the two clamping blocks 13 clamp the goods, and then the pulling force applied to the rotating wheel 2 is removed. Under the elastic force of the second spring, the rectangular rod 5 and the round rod 12 will slide relative to each other until each clamping block 17 is respectively engaged with the corresponding clamping groove 18, so as to prevent the limit plate 16 from moving, and the distance between the first clamp arm 1 and the second clamp arm 11 cannot change. When the clamp arm is collided by external force, the distance between the first clamp arm 1 and the second clamp arm 11 will not increase, thereby effectively preventing the clamp arm from being separated from the goods, and the positioning device 7 on the first clamp arm 1 will not be separated from the goods, which has a better tracking effect on cold chain logistics.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
