Description

Technical Field

[0001] This utility model relates to the technical field of sanitation, specifically a foldable urban greening seedling support frame. Background Technology

[0002] Urban greening seedling support frames are temporary auxiliary structures set up during the construction of landscaping projects to ensure the stability and normal growth of newly planted trees (especially arbor trees). They have the effects of wind resistance, root reinforcement, maintaining uprightness, and preventing mechanical damage.

[0003] In existing technologies, support frames typically use mainstream triangular / quadrilateral supports, with the tree trunk as the center, and three or four support poles (commonly made of cedar, pine, or bamboo) are driven evenly around it. The upper ends of the poles contact the tree trunk and are then fixed with binding materials (such as special binding straps, hemp rope, antique rope, etc.) to form a stable triangular or quadrangular pyramidal structure.

[0004] Triangular or quadrangular supports require on-site setup by operators, which slows down their work. To address this issue, we offer a foldable urban greening seedling support frame. Utility Model Content

[0020] Reference Figure 1The side wall of the fixed rod 11 is provided with two sets of sliding grooves 13. The two sets of sliding grooves 13 are symmetrically arranged in the vertical direction. Each set of sliding grooves 13 has two grooves. The two sliding grooves 13 are arranged sequentially in the vertical direction. In this embodiment, the sliding groove 13 is preferably a semi-circular groove.

[0021] Reference Figure 1 Each slide groove 13 corresponds to a support rod 14. The support rod 14 is vertically arranged, and the side wall of the support rod 14 is provided with a slider. There are two sliders. Each slide groove 13 corresponds to a slider. The slider can slide along the slide groove 13. The slider is fixedly connected to the fixed rod 11 and the slider is fixedly connected to the support rod 14.

[0022] Reference Figure 1 and Figure 2 Each support rod 14 is provided with a fixing device 3. The fixing device 3 includes a first bearing rod 31 and a second bearing rod 32. The first bearing rod 31 and the second bearing rod 32 are arranged in sequence along the horizontal direction. The first bearing rod 31 is fixedly connected to the bottom of the support rod 14, and the second bearing rod 32 is connected to the first bearing rod 31 through a rotating shaft. The ends of the first bearing rod 31 and the second bearing rod 32 that are close to each other and the ends of the second bearing rod 32 that are far away from the first bearing rod 31 are both provided with through grooves. Ground nails 2 are provided in the through grooves and can slide along the opening direction of the through grooves.

[0023] Reference Figure 1 and Figure 2 Both ends of the second bearing rod 32 and the first bearing rod 31 are provided with positioning rods 33. In this embodiment, the positioning rods 33 are vertically arranged. The positioning rods 33 are preferably rectangular rods. The positioning rods 33 are vertically arranged, and both sides of the positioning rods 33 are provided with guide grooves 34, which are vertically arranged.

[0024] Reference Figure 1 and Figure 2 A lifting assembly 35 is provided above both the first support rod 31 and the second support rod 32. The lifting assembly 35 includes a screw 351 and a handwheel 352. In this embodiment, the screw 351 is vertically arranged and centrally located in the middle of the first support rod 31 and / or the second support rod 32. The screw 351 is rotatably connected to the first support rod 31 and / or the second support rod 32 by means of bearing connection. The handwheel 352 is located at the bottom of the screw 351, and the handwheel 352 and the screw 351 are coaxially fixedly connected by means of key connection.

[0025] Reference Figure 1 and Figure 2The lifting assembly 35 also includes a lifting rod 36, which is horizontally arranged and the long side of the lifting rod 36 is parallel to the long side of the first bearing rod 31 and / or the second bearing rod 32. The lifting rod 36 is rotatably connected to the screw 351. The end of the lifting rod 36 is provided with a horizontal mounting part, which is located in the guide groove 34, so that the lifting rod 36 can slide along the long side of the guide groove 34 under the action of the screw 351 and the horizontal mounting part.

[0026] Reference Figure 1 and Figure 2 The top walls of the first bearing rod 31 and the second bearing rod 32 are provided with positioning grooves 37, wherein the positioning grooves 37 are horizontally arranged.

[0027] Reference Figure 1 and Figure 2 The fixing device 3 also includes an anti-slip component 38, which includes two push rods 381. The two push rods 381 are arranged in an inverted V shape. Both push rods 381 are rotatably connected to the lifting rod 36 through a pivot. The rotatable connection point between the two push rods 381 and the lifting rod 36 is located in the middle of the push rods 381.

[0028] Reference Figure 1 and Figure 2 The first bearing rod 31 and the second bearing rod 32 are provided with two sets of limiting grooves 371 at the bottom of the positioning groove 37. The two sets of limiting grooves 371 are arranged sequentially along the long side of the first bearing rod 31 and / or the second bearing rod 32, respectively. Here, the two sets of limiting grooves 371 are composed of multiple limiting grooves 371, which are arranged linearly. Here, the groove depth of the limiting grooves 371 gradually becomes shallower from the end of the first bearing rod 31 and / or the second bearing rod 32 toward the middle.

[0029] Reference Figure 1 and Figure 2 The bottom of the two push rods 381 is provided with mounting blocks 382. The mounting blocks 382 are rotatably connected to the push rods 381 by bearing connection. The bottom of the mounting blocks 382 is provided with a receiving groove 383. The opening direction of the receiving groove 383 is vertically downward. The receiving groove 383 is provided with an adjusting bolt 384, a mounting plate 385, a spring 386 and a locking block 387. The adjusting bolt 384 is vertically set and is threadedly connected to the mounting block 382. The mounting plate 385 is located in the inner cavity of the receiving groove 383 and the side wall of the mounting plate 385 is attached to the inner wall of the receiving groove 383. In this embodiment, the locking block 387 fits into the limiting groove 371. The two ends of the spring 386 are fixedly connected to the mounting plate 385 and the locking block 387 respectively. The extension and contraction direction of the spring 386 is vertical.

[0030] In this embodiment, the operator rotates the handwheel 352 to rotate the screw 351, which in turn causes the lifting rod 36 to slide vertically. At this time, the top rod 381 rotates along the lifting rod 36, causing the mounting block 382 to slide. The locking block 387 contacts the side wall of the limiting groove 371, causing the spring 386 to compress and contract. The top rod 381 slides, so that the locking block 387 is located in different limiting grooves 371, thus providing an auxiliary limiting effect on the top rod 381. When it is necessary to lower the lifting rod 36, the operator rotates the adjusting bolt 384 to slide the mounting plate 385, which causes the locking block 387 to leave the limiting groove 371 and is no longer limited by the limiting groove 371, allowing the mounting block 382 to slide in the positioning groove 37.

[0031] Reference Figure 1 and Figure 3 The top wall of the lifting rod 36 is provided with multiple fitting components 39. The multiple fitting components 39 are arranged at intervals along the long side of the lifting rod 36. The fitting component 39 includes a fixed tube 391, an extension rod 392 and a set screw 393. The fixed tube 391 is rotatably connected to the lifting rod 36. The extension rod 392 passes through the fixed tube 391 and slides along the axial direction of the fixed tube 391. The set screw 393 passes through the fixed tube 391 and is threadedly connected to the fixed tube 391. The set screw 393 abuts against the extension rod 392. The end of the extension rod 392 away from the fixed tube 391 is provided with an abutment plate 394. The end of the abutment plate 394 away from the extension rod 392 is provided with a flexible pad 395.

[0032] The implementation principle of a foldable urban greening seedling support frame is as follows: the operator first places the fixing rod 11 in the corresponding position, then rotates the first bearing rod 31 and the second bearing rod 32, and then fixes the fixing plate 12, the first bearing rod 31 and the second bearing rod 32 to the corresponding positions on the ground through the ground nail 2.

[0033] Rotating the handwheel 352 causes the screw 351 to rotate, and the horizontal mounting part at the end of the lifting rod 36 is located in the guide grooves 34 on both sides, thereby causing the lifting rod 36 to slide in the vertical direction. During this process, the mounting block 382 slides along the positioning groove 37, and at the same time, the locking block 387 is located in different limit grooves 371, thereby preventing the lifting rod 36 from falling and ensuring overall safety.

[0034] When it is necessary to lower the lifting rod 36, rotate the adjusting bolt 384 so that the locking block 387 is retracted into the receiving groove 383. At this time, the locking block 387 is no longer located in the positioning groove 37, thereby allowing the mounting block 382 to slide along the positioning groove 37.

[0035] The operator rotates the fixing tube 391 and slides the extension rod 392, so that the abutment plate 394 and the flexible pad 395 can abut against the seedling to limit the seedling.
