Description

Technical Field

[0002] With the continuous improvement of people's living standards, the modern cold chain logistics industry has become increasingly developed, and higher requirements have been put forward for cold chain logistics equipment. Short-distance cold chain logistics distribution requires a large number of small passive cold chain boxes, which use cold storage plates for refrigeration. Several cold storage plates are installed on the wall of a passive cold chain box. How to achieve the quick and safe installation and replacement of cold storage plates on the inner wall of the box is of great value.

[0003] The existing slots for installing cold storage plates are upper and lower slots of fixed sizes. The upper and lower tops of the cold storage plates are stuck in the slots. In order to smoothly install the cold storage plates, a large gap is left between the cold storage plates and the slots. This causes the cold storage plates to inevitably vibrate and bump during cold chain transportation, and also to hit the box walls and slot frames. On the one hand, this will reduce the service life of the cold storage plates, and on the other hand, it will generate additional vibration loads on the box body, reducing the service life of the box body and generating vibration noise. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that there is a large gap between the cold storage plate and the slot, which causes the cold storage plate to inevitably vibrate and bump during cold chain transportation, and also hit the box wall and the slot frame. On the one hand, it will reduce the service life of the cold storage plate, and on the other hand, it will generate a vibration additional load on the box body, reducing the service life of the box body and generating vibration noise. A passive cold chain box with an elastic clamping mechanism for a cold storage plate is proposed.

[0007] Preferably, the elastic clamping mechanism 1 and the elastic clamping mechanism 2 are both composed of a pressure plate, a torsion spring, a long shaft, a first pin, a second pin, a bolt and a support seat;

[0008] The inner walls of the multiple support seats are fixedly connected to the inner box wall by bolts, the upper inner wall of the support seat is rotatably connected to the pressure plate through a long axis, and a plurality of torsion springs are distributed on the front side of the outer wall of the long axis. The upper part of the torsion spring is connected to the pressure plate through pin shaft 1, and the lower part of the torsion spring is connected to the inner box wall through pin shaft 2.

[0009] Preferably, an elastic retaining ring is installed at the end of the long shaft.

[0010] Preferably, the inner sides of the outer walls of the upper and lower pressing plates are respectively in contact with the first cold storage plate and the second cold storage plate.

[0011] Preferably, the pressing plate is composed of a silicone rubber coating layer, an operating handle, a bridge plate, a clip and a hollow shaft;

[0012] The inner sides of the outer walls of adjacent clips are fixedly connected via a bridge plate, a silicone rubber coating layer is fixedly connected to the upper part of the outer wall of the clip, a hollow shaft is fixedly connected to the lower end of the clip, and an operating handle is fixedly connected to the outer wall of the right clip.

[0013] Preferably, the inner wall of the hollow shaft is rotatably connected to the long shaft.

Then, when the operating handle is released, the pressing plate will press the cold storage plate, thereby fixing the cold storage plate. In addition, the special design of the clamping mechanism reduces the bumps, vibrations and noises of the cold storage plate during logistics transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] See attached Figure 1-8 : In this embodiment, the elastic clamping mechanism 1 3 and the elastic clamping mechanism 2 5 are both composed of a pressure plate 301, a torsion spring 302, a long shaft 303, a pin 1 305, a pin 2 306, a bolt 307 and a support seat 308;

[0028] The inner walls of multiple support seats 308 are fixedly connected to the inner box wall 1 by bolts 307, and the upper inner wall of the support seat 308 is rotatably connected to the pressure plate 301 through the long axis 303. Multiple torsion springs 302 are distributed on the front side of the outer wall of the long axis 303. The elastic coefficient of the torsion spring 302 can be determined according to the specific usage.

[0029] See attached Figure 1-8 : In this embodiment, the pressing plate 301 is composed of a silicone rubber coating layer 301a, an operating handle 301b, a bridge plate 301c, a clip 301d and a hollow shaft 301e;

[0031] A pressure plate 301 composed of several clips 301d can rotate around the rotating axis. A hollow shaft 301e is set in sections on one side of the pressure plate 301.
