Description

Technical Field

[0001] The utility model relates to the technical field of seedling raising racks, and particularly relates to a seedling raising rack. Background Art

[0002] In modern planting greenhouses, seedlings are usually collectively placed on seedling raising racks for raising. Existing seedling raising racks are generally fixed into a whole by welding or bolts. The seedling raising racks can be single-layer or multi-layer. Generally, steel frames are transported to the site and then assembled. If the assembled rack body is transported again, since the rack body cannot be folded, it occupies space and is inconvenient to transport. If it is disassembled and transported again, it is extremely inconvenient. Summary of the Utility Model

[0004] To achieve the above purpose, the technical scheme adopted by the utility model is as follows: A seedling raising rack, comprising:

[0005] A pair of support rods, the pair of support rods are horizontally arranged at intervals;

[0006] Support legs, arranged at both ends of the bottom of each support rod;

[0007] Leg connecting rods, connected between two support legs at the same end. Both ends of the leg connecting rod are respectively hinged to a first hinge seat arranged on the side wall of the support leg. The leg connecting rod is divided into two rod bodies by the middle part, and the two rod bodies are hinged by a hinge arranged at the bottom thereof;

[0008] A first diagonal brace rod, used to strengthen the support between the support leg and the leg connecting rod. One end of the first diagonal brace rod is hinged to a second hinge seat arranged on the rod body, and the other end of the first diagonal brace rod is fixedly connected to the side wall of the support leg through a fastener.

[0009] Further, the fastener includes a screw rod, a lower nut and an upper nut threadedly connected to the screw rod. The lower end of the screw rod is hinged to a third hinge seat arranged on the first diagonal brace rod. A fixed seat is arranged on the side wall of the support leg, and a U-shaped bayonet for the screw rod to be inserted into is arranged on the fixed seat. The lower nut and the upper nut are respectively located at the lower part and the upper part of the U-shaped bayonet.

[0010] Further, the upper nut is a wing nut.

[0011] Further, the support leg is a telescopic support leg.

[0012] Further, the support leg includes an inner rod and a telescopic outer sleeve slidably sleeved outside the inner rod. A fastening bolt for fastening the inner rod and the telescopic outer sleeve is arranged at the lower part of the telescopic outer sleeve.

[0013] Furthermore, a second diagonal brace is welded between the support rod and the support leg.

[0014] Due to the above technical solutions, the present utility model has the following beneficial effects:

[0015] The leg link of the present embodiment is composed of rod bodies hinged in the middle through hinges. The two ends of the leg link are hinged to the support leg. At the same time, one end of the first diagonal brace is hinged to the leg link, and the other end is fixedly connected to the side wall of the leg link through a fastener. When the fastener is loosened, the leg link is rotated and folded through the hinge, so that the two support rods are close to each other, thereby realizing the disassembly and folding of the frame, which is convenient for handling and occupies a small space.

[0021] As used herein, the reference to "embodiment" means that the specific features, structures or characteristics described in connection with the embodiment may be included in at least one embodiment of the present utility model. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein may be combined with other embodiments.

[0022] As Figure 1 , Figure 2 shown, a seedling-raising rack includes a pair of supporting rods 1, supporting legs 2, leg connecting rods 3 and first diagonal braces 4.

[0023] Referring to Figure 1 , a pair of supporting rods 1 are horizontally arranged at intervals. In this embodiment, the supporting rod 1 is a hollow square steel, and the interval width between the two supporting rods 1 is 50 cm.

[0024] The supporting legs 2 are used to support the supporting rods 1 and are arranged at both ends of the bottom of each supporting rod 1; in this embodiment, the height from the supporting leg 2 to the top surface of the supporting rod 1 is 70 cm.

[0025] Referring to Figure 2 , the leg connecting rods 3 are connected between two supporting legs 2 at the same end. Both ends of the leg connecting rod 3 are respectively hinged to the first hinge seats 32 provided on the side walls of the supporting legs 2. The leg connecting rod 3 is divided into two rod bodies by the middle part, and the two rod bodies are hinged by a hinge 31 installed at their bottoms. In this embodiment, the first hinge seat 32 is a U-shaped structure, so that its bottom plays a role of supporting and limiting.

[0026] The first diagonal braces 4 are used to strengthen the support between the supporting legs 2 and the leg connecting rods 3. One end of the first diagonal brace 4 is hinged to the second hinge seat 33 provided on the rod body, and the other end of the first diagonal brace 4 is fixedly connected to the side wall of the supporting leg 2 through a fastener.

[0027] Referring to Figure 3 , for the convenience of disassembly and assembly, in this embodiment, the fastener includes a screw 61 and a lower nut 62 and an upper nut 63 threadedly connected to the screw 61. The lower end of the screw 61 is hinged to the third hinge seat 41 provided on the first diagonal brace 4, and a fixed seat 5 is fixed on the side wall of the supporting leg 2. A U-shaped bayonet 51 for the screw 61 to be inserted into is provided on the fixed seat 5, and the lower nut 62 and the upper nut 63 are respectively located below and above the U-shaped bayonet 51. The fastener can also be a vertically arranged fixing piece and is fixedly connected to the side wall of the supporting leg 2 by means of bolts

[0028] Preferably, the upper nut 63 is a wing nut. This structure is convenient for installation and disassembly, and workers can turn the upper nut 63 without the aid of tools, which is convenient for disassembly and assembly.

[0029] Preferably, the support leg 2 is a telescopic leg. Specifically, the support leg 2 includes an inner rod 21 and a telescopic outer sleeve 22 sleeved outside the inner rod 21. A fastening bolt 23 for fastening the inner rod 21 and the telescopic outer sleeve 22 is provided at the lower part of the telescopic outer sleeve 22. The support leg 2 can be telescopically adjusted in height, and the height of the frame can be set as needed. When carrying, the support leg 2 is adjusted to a contracted state, which is more convenient for transportation.

[0030] In order to further strengthen the firmness of the entire seedling-raising frame structure, a second diagonal brace is welded between the support rod 1 and the support leg 2.

[0031] When disassembling, by loosening the upper nut 63, the screw rod 61 is rotated clockwise to disengage from the U-shaped bayonet 51, and then the two rod bodies are rotated and folded around the hinge 31, so that the two support rods 1 are close to each other, thereby realizing the disassembly and folding of the frame, which occupies a small space and is convenient for carrying. When installing, the two support rods 1 are separated, the leg connecting rod 3 is unfolded, and then the screw rod 61 is rotated and inserted into the U-shaped bayonet 51, and then the upper nut 63 is tightened. When in use, the seedling pots are arranged on the two support rods 1.

[0032] The above has generally described the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
