Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figure 1-4 This utility model provides a technical solution: an adjustable height fresh agricultural product storage shelf, including a support base 1 and support legs 6. A limiting post 2 is fixedly connected to one end of the upper part of the support base 1. Two sets of limiting posts 2 are provided, which are symmetrically arranged at both ends above the support base 1. Multiple sets of limiting holes 3 are opened on the side of the limiting post 2. An adjustment mechanism 4 is provided on one end of the side of the limiting post 2.

[0024] The placement adjustment mechanism 4 includes a connecting block 41 disposed at one end of the side of the limiting post 2, a placement bucket 42 fixedly connected to one end of the side of the connecting block 41, an adjustment component 43 for adjusting the height disposed at one end inside the connecting block 41, and a limiting block 44 fixedly connected to one end of the side of the connecting block 41.

[0025] The adjusting assembly 43 includes a rotating rod 431 rotatably connected to the side of the connecting block 41. A handwheel 432 is fixedly connected to one end of the rotating rod 431. A gear 433 is fixedly connected to one end of the rotating rod 431. A rack 434 is provided at one end of the gear 433. The gear 433 meshes with the rack 434. A first spring 435 is fixedly connected to one end of the rack 434. A connecting frame 436 is fixedly connected to one end of the rack 434. A second spring 437 is fixedly connected to one end of the connecting frame 436. The first spring 435 and the second spring 437 can push the locking strip 438 to slide into the limiting hole 3. The locking strip 438 is fixedly connected to one end of the connecting frame 436. The locking strip 438 can be inserted into the limiting hole 3 for positioning. A trapezoidal block 439 is fixedly connected to one end of the locking strip 438. The trapezoidal block 439 can make the locking strip 438 insert into the limiting hole 3 more accurately.

[0026] The upper part of the limiting block 44 is provided with a through groove that can slide on the side of the limiting post 2. One end of the side of the limiting block 44 is provided with a hole for the trapezoidal block 439 and the locking strip 438 to pass through. There are two sets of limiting blocks 44, which are symmetrically arranged at both ends of the side of the connecting block 41. The two sets of limiting blocks 44 can better ensure that the placement bucket 42 is parallel to the support base 1 and prevent the placement bucket 42 from tilting.

[0027] The connecting block 41 has a cavity for accommodating the adjustment component 43. The rack 434, connecting frame 436, and connecting block 41 all slide within the cavity. The first spring 435 and the second spring 437 are fixedly connected to the connecting block 41 inside the connecting block 41. Three sets of adjustment mechanisms 4 are arranged in an array on the side of the limiting post 2. The three sets of adjustment mechanisms 4 can hold different kinds of fresh agricultural products, providing buyers with more choices.

[0028] The rack 434, the first spring 435, the connecting frame 436, the second spring 437, the retaining strip 438 and the trapezoidal block 439 are arranged in two sets, and the two sets are distributed in opposite directions. Both sets of racks 434 are adapted to gears 433. When gears 433 rotate, they can drive the two sets of racks 434 to move synchronously in opposite directions.

[0029] By rotating the handwheel 432, the rotating rod 431 and gear 433 are driven to rotate. When the gear 433 rotates, it drives the two sets of racks 434 to move synchronously in opposite directions. When rotated clockwise, the locking bar 438 and trapezoidal block 439 can be driven to retract into the connecting block 41 and disengage from the limiting hole 3. At this time, the placement bucket 42 can be manually raised or lowered to adjust it to a suitable position. When the handwheel 432 is released, the compressed first spring 435 and second spring 437 will drive the trapezoidal block 439 to insert into the limiting hole 3. Due to the slope of the trapezoidal block 439, the locking bar 438 can be better inserted into the limiting hole 3, thereby locking the position of the placement adjustment mechanism 4.

[0030] Example 2:

[0031] Please see Figure 5-6This utility model provides a technical solution: an adjustable height fresh agricultural product storage shelf. Embodiment 2 has the same main structure as Embodiment 1. Based on Embodiment 1, Embodiment 2 adds a limiting component 5 to the connecting block 41. The limiting component 5 includes a fixing block 51 disposed at one side end of the connecting block 41. The fixing block 51 is fixed to the side of the rotating rod 431. A third spring 52 is fixed to one end inside the connecting block 41. The third spring 52 can drive the inclined block 54 to reset. A connecting plate 53 is fixed to one side end of the third spring 52. An inclined block 54 is fixed to one side end of the connecting plate 53. A fixing rod 55 is fixed to one side end of the connecting plate 53. A button 56 is fixed to one side end of the fixing rod 55. Pressing the button 56 can drive the fixing rod 55 to push the connecting plate 53 and the inclined block 54 to retract into the connecting block 41.

[0032] The connecting block 41 has a cavity inside that is compatible with the limiting component 5. The third spring 52 is fixed in the cavity inside the connecting block 41. The connecting plate 53, the inclined block 54 and the fixing rod 55 all slide in the cavity inside the connecting block 41. The fixing block 51 is compatible with the inclined block 54. The part of the inclined block 54 that protrudes from the connecting block 41 is an inclined surface. When the fixing block 51 rotates with the rotating rod 431, it can squeeze the inclined surface and cause the inclined block 54 to retract inward. When the fixing block 51 is below the inclined block 54, since the bottom of the inclined block 54 is a flat surface, it can prevent the fixing block 51 from rotating.

[0033] When the adjustment is made by rotating the rotating rod 431 clockwise, the fixed block 51 fixed to the side will rotate together. The rotating fixed block 51 will squeeze the inclined surface on the side of the inclined block 54, causing it to retract inward and into the cavity opened inside the connecting block 41. When the fixed block 51 passes the inclined block 54, the third spring 52 will push the inclined block 54 to reset, so that one end of it protrudes out of the connecting block 41. When the fixed block 51 is below the inclined block 54, since the bottom of the inclined block 54 is a flat surface, it can prevent the fixed block 51 from rotating, thereby positioning the fixed block 51. This avoids the situation where the first spring 435 and the second spring 437 push the locking strip 438 into the limiting hole 3 if it is not adjusted to the appropriate position during the adjustment process, making it more convenient to use.
