Description

Technical Field

[0001] This utility model relates to the field of flower preservation equipment technology, and in particular to a device for preserving fresh-cut flowers during the logistics process. Background Technology

[0002] Currently, in the logistics process, providing an optimized environment for cut flowers to extend their blooming period and maintain their freshness is crucial. This is typically achieved using refrigerated storage units (SSUs). These SSUs are designed to provide a suitable temperature and humidity environment for the cut flowers, preventing them from losing water or wilting. A suitable environment also helps slow down the respiration and aging process of the flowers. These SSUs usually come with built-in supports or racks to properly arrange and support the cut flowers, ensuring they are not compressed or squeezed during preservation, maintaining their natural shape and structure, thus extending their shelf life. In existing technology, the racks in SSUs typically use an automatically adjustable structure. However, during vertical adjustment, the lifting equipment occupies a certain amount of space, resulting in large gaps between each shelf. This design leads to a waste of space resources when storing small items. Utility Model Content

[0003] The purpose of this invention is to address the issue that in the existing technology, the shelves in the cold storage are usually designed with an adjustable structure. However, because the lifting equipment occupies a certain amount of space, the interval between each shelf is relatively large. When small items need to be stored, this design will lead to a waste of space resources. Therefore, this invention proposes a device for preserving fresh-cut flowers during the logistics process.

[0004] The technical solution of this utility model is as follows: A device for preserving fresh-cut flowers during logistics includes a preservation chamber and multiple support frames disposed within the preservation chamber. It further includes: multiple flower racks arranged linearly within the support frames; a slide rail mechanism disposed within the support frames to support the vertical adjustment of the flower racks; a switching mechanism installed within the flower racks to fix the adjusted flower racks onto the slide rail mechanism; and a telescopic slot formed in the middle of the flower racks, the telescopic slot containing a lifting mechanism to increase or decrease the distance between the flower racks.

[0005] Optionally, the switching mechanism includes a movable cavity formed inside the flower stand, a pair of positioning slots on the flower stand, a pair of telescopic rods slidably connected inside the flower stand, a pair of driving rods fixedly connected to the ends of the telescopic rods inside the movable cavity, and a handle that moves through the movable cavity at the bottom of the flower stand. Both ends of the handle are fixedly connected to a retaining block that abuts against the driving rods, causing the telescopic rods to retract into the flower stand.

[0006] Optionally, the switching mechanism further includes a sliding abutment plate that is slidably connected in the movable cavity to abut against the corresponding driving rod, and a return spring is fixedly connected to the middle of the sliding abutment plate.

[0007] Optionally, a spherical slider is fixedly connected to the end of the driving rod away from the telescopic insertion rod.

[0008] Optionally, the end of the pressing block away from the handle is provided with a positioning notch for locking the driving rod, both ends of the handle are fixedly fitted with annular locking blocks, and the end of the handle near the annular locking blocks is fitted with a push spring. One end of the push spring is fixedly connected to the annular locking block, and the other end of the push spring is fixedly connected to the flower stand.

[0009] Optionally, the grip handle has multiple linearly arranged acupressure slots for fingers to be inserted.

[0010] Optionally, the slide rail mechanism includes a pair of support rods fixedly connected inside the flower stand and engaging with positioning grooves. The support rods are provided with anti-slip grooves for inserting the ends of telescopic rods. The support frame is also fixedly connected with a pair of support slide rails, and the flower stand is provided with a pair of grooves engaging with the support slide rails.

[0011] Optionally, the lifting mechanism includes a multi-stage cylinder fixedly connected in a telescopic slot. The piston rods of the multi-stage cylinders are all fixedly connected to a stop rod. The end of the stop rod away from the multi-stage cylinder is provided with an inclined abutment surface that abuts against the corresponding grip handle to open the switch mechanism.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This invention utilizes the combined structure of flower racks, support frames, slide rails, lifting mechanisms, and switching mechanisms to achieve a smaller spacing between flower racks and to rationally arrange goods, making full use of every inch of space. This helps to store more goods in a limited area and avoids space waste. Simultaneously, when the multi-stage cylinder malfunctions and cannot provide support, the telescopic rod automatically engages in the anti-slip groove, thereby increasing the friction of the flower rack moving downwards on the support frame, ensuring the shelf moves slowly and smoothly downwards.

[0026] Example

[0027] like Figures 1 to 5 As shown, this utility model proposes a device for preserving fresh-cut flowers during logistics, including a preservation chamber 1 and multiple support frames 11 disposed within the preservation chamber 1. It also includes: multiple flower racks 2 arranged linearly and slidably connected within the support frames 11, each flower rack 2 having multiple linearly arranged strip-shaped holes to reduce weight and increase air permeability of the fresh-cut flowers; a slide rail mechanism disposed within the support frames 11 to support the vertical adjustment of the flower racks 2; a switching mechanism installed within the flower racks 2 to fix the adjusted flower racks 2 onto the slide rail mechanism; and a telescopic slot 201 located in the middle of the flower racks 2, the telescopic slot 201 containing a lifting mechanism to increase or decrease the distance between the flower racks 2. The lifting mechanism includes a multi-stage cylinder 202 fixedly connected within the telescopic slot 201, the multi-stage cylinder 202 being a cylinder with a long stroke. Each piston rod of the multi-stage cylinder 202 is fixedly connected to a stop rod 203. The end of the stop rod 203 away from the multi-stage cylinder 202 is provided with an inclined abutment surface 204 that abuts against the corresponding grip handle 3 to open the switch mechanism.

[0028] Furthermore, the switching mechanism includes a movable cavity 24 formed within the flower stand 2. The flower stand 2 has a pair of positioning grooves 22. A pair of telescopic rods 23 are slidably connected inside the flower stand 2. Inside the movable cavity 24, there is a pair of driving rods 243 fixedly connected to the ends of the telescopic rods 23. A spherical slider 244 is fixedly connected to the end of the driving rod 243 away from the telescopic rods 23. The spherical slider 244 facilitates smoother sliding of the driving rods 243 within the movable cavity 24. The bottom of the flower stand 2 has a handle 3 that extends through the movable cavity 24. The handle 3 has multiple linearly arranged finger-pressure slots 31 for inserting fingers, allowing for a tighter grip between the hand and the handle 3. Both ends of the handle 3 are fixedly connected to abutting blocks 35 that abut against the driving rod 243 and cause the telescopic rod 23 to retract into the flower stand 2. The switching mechanism also includes a sliding abutment plate 241 that is slidably connected in the movable cavity 24 and abuts against the corresponding driving rod 243. A return spring 242 is fixedly connected in the middle of the sliding abutment plate 241. The return spring 242 causes the pair of telescopic rods 23 to automatically return to their original state of being inserted into the support rod 102.

[0029] The pressing block 35 has a positioning notch 34 at the end furthest from the handle 3 to engage the driving rod 243. The positioning notch 34 ensures that the pressing block 35 engages the driving rod 243 after pressing against it. Both ends of the handle 3 are fixedly fitted with annular locking blocks 33, and the end of the handle 3 near the annular locking blocks 33 is fitted with a push spring 32. The push spring 32 ensures that the handle 3 returns to its original position when not being gripped, allowing for repeated use. One end of the push spring 32 is fixedly connected to the annular locking block 33, and the other end of the push spring 32 is fixedly connected to the flower stand 2.

[0030] Furthermore, the slide rail mechanism includes a pair of support rods 102 fixedly connected inside the flower stand 2, which engage with positioning grooves 22. Each support rod 102 has an anti-slip groove 103 for inserting the end of a telescopic rod 23. The anti-slip groove 103 has a rubber pad to increase friction with the telescopic rod 23. A pair of support slide rails 101 are also fixedly connected inside the support frame 11, and the flower stand 2 has a pair of grooves 21 that engage with the support slide rails 101.

[0031] In this embodiment, when a device for preserving fresh-cut flowers is required during the logistics process, such as... Figure 1As shown, once the multi-stage cylinder 202 inside the flower stand 2 is activated, the piston rod of the multi-stage cylinder 202 will push the corresponding abutment rod 203 to move. The inclined abutment surface 204 at the end of the abutment rod 203 abuts against the corresponding handle 3, thereby causing both ends of the handle 3 to drive the corresponding pressing blocks 35 to move. The pressing blocks 35 drive the positioning notch 34 on them to lock the driving rod 243, so that the end of the driving rod 243 near the spherical slider 244 abuts against the sliding plate 241. The other end of the driving rod 243 drives the corresponding telescopic insertion rod 23 to retract into the flower stand 2. At this time, the flower stand 2 above can be adjusted up and down in the support frame 11 by pushing the corresponding multi-stage cylinder 202. The flower stand 2 slides smoothly up and down in the support frame 11 with the support of a pair of support slide rails 101 and anti-slip grooves 103. Once the flower stand 2 is positioned on the support slide rail 101 and anti-slip groove 103, simply activate the multi-stage cylinder 202 to disengage the abutment rod 203 from the grip handle 3. At this point, the grip handle 3, through the elastic thrust of the end spring 32, causes a pair of annular locking blocks 33 to move the grip handle 3 back to its original position. Both ends of the grip handle 3 move the corresponding abutment blocks 35, preventing the abutment blocks 35 from blocking the corresponding drive rod 243. Simultaneously, a pair of sliding abutment plates 241, through the elastic thrust of the reset spring 242, push the corresponding movable cavity 24 and telescopic insertion rod 23 in sequence, causing the end of the telescopic insertion rod 23 away from the spherical slider 244 to re-insert into the anti-slip groove 103. This buffers the flower stand 2 as it slides downward within the support frame 11, preventing a sudden drop within the support frame 11.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
