Description

Technical Field

[0001] This utility model relates to the field of agricultural greenhouse technology, and in particular to a keel for a greenhouse that can be quickly assembled. Background Technology

[0002] The main components of a greenhouse frame are tie rods, compression rods, columns, and arches made of greenhouse composite materials, which cover the plastic film. This type of greenhouse has an arched shape and occupies a large area. It has a very good heat absorption effect, is easy to build, and has a very low construction cost. This type of greenhouse has become one of the most widely used tools for agricultural production in rural areas.

[0003] In the prior art, such as Chinese Patent No. CN218541160U, there is a type of keel for a spliced ​​greenhouse. This keel includes a crossbeam keel; curved keels located on both sides of the crossbeam keel, with a snap-fit ​​splicing mechanism between the curved keels and the crossbeam keel; a fixed installation mechanism located above and below the snap-fit ​​splicing mechanism; and a telescopic mechanism located in the middle of the crossbeam keel. This spliced ​​greenhouse keel connects the crossbeam keel and the curved keel, making the keel suitable for the curved roof surface of the greenhouse. The snap-fit ​​splicing mechanism between the curved keel and the crossbeam keel reduces the possibility of misalignment. The telescopic mechanism in the middle of the crossbeam keel extends the keel, reducing the height difference between the crossbeam keels and preventing dust from entering and accelerating the aging of the telescopic mechanism parts. This makes the keel suitable for constructing greenhouse roofs of various sizes.

[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are that the assembly process involves welding, which, although stable, is not easy to disassemble. In addition, the device lacks a folding design for the keel, which increases the difficulty of carrying it. Utility Model Content

[0005] The purpose of this invention is to solve the problem of inconvenience in disassembly in the prior art, and at the same time, to solve the problem of inconvenience in carrying the keel.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a quick-assembly greenhouse keel: comprising keel one and keel two, the quick-assembly greenhouse keel further comprising:

[0007] Two rectangular blocks are respectively installed on one side of the first keel and the second keel;

[0008] Two folding components, which can rotate around the internal axis of the rectangular block, are installed on the rectangular block to reduce space occupation during carrying.

[0009] The assembly is installed between the two rectangular blocks;

[0010] The splicing component can move from both ends toward the middle along a horizontal line to splice and fix the first keel and the second keel.

[0011] In a preferred embodiment, the folding member includes:

[0012] A rotating block is rotatably mounted on one side of the rectangular block;

[0013] A retaining ring is fixedly installed at the bottom of the rotating block.

[0015] In a preferred embodiment, the folding member further includes:

[0016] The disassembly ring is embedded inside the second keel;

[0017] A support rod is connected between the fixing ring and the disassembly ring;

[0018] The support rod is rotatably connected to the fixing ring and is fixedly connected to the disassembly ring.

[0019] The technical effect of adopting the above-mentioned further solution is that the support rod can drive the rotating block to flip through the fixed ring, and can also achieve a supporting effect on the fixed ring.

[0020] In a preferred embodiment, the folding member further includes:

[0021] Hex bolts are embedded within the disassembly ring;

[0022] The hexagonal bolt penetrates through the second keel.

[0023] The technical effect of adopting the above-mentioned further solution is that the hexagonal bolt can fix the disassembly ring in the first keel and the second keel.

[0024] In a preferred embodiment, the assembly includes:

[0025] A fixing tube is installed on one side of the rotating block;

[0026] A sliding column is embedded inside the fixed tube;

[0027] The sliding column can slide horizontally within the fixed tube.

[0028] The technical effect of adopting the above-mentioned further solution is that the fixed tube can form a track for the sliding column, ensuring that the path of the hollow column runs in the horizontal direction.

[0029] In a preferred embodiment, the assembly includes:

[0030] A hollow column is installed on one side of the sliding column;

[0031] Two springs are installed on one side of the fixed tube;

[0032] The other side of each of the two springs is connected to the hollow column.

[0033] The technical effect of adopting the above-mentioned further solution is that the spring drives the hollow column to return to its original position, and also ensures that the sliding column is always embedded in the fixed tube.

[0034] In a preferred embodiment, the assembly includes:

[0035] Two slots are formed on the inner wall of the hollow column;

[0036] Two springs are installed in the two slots, and beveled blocks are installed on the other side of each spring.

[0037] The technical effect of adopting the above-mentioned further solution is that the second spring supports the angled block, so that the angled block can move in the vertical direction.

[0038] In a preferred embodiment, the assembly includes:

[0039] A hemispherical head post is installed on one side of the rotating block connected to the keel;

[0040] A rhomboid ring is fitted onto the hemispherical head post;

[0041] The pipe wall is embedded in a rotating block connected to the keel;

[0042] The rhomboid ring can move in a straight line on the surface of the hemispherical head column.

[0043] The technical effect of adopting the above-mentioned further solution is that the hemispherical head column can be embedded inside the hollow column to achieve a splicing effect.

[0044] As a preferred embodiment, the quick-assembly greenhouse keel also includes:

[0045] A threaded hole is formed at the bottom of the hollow column;

[0046] Threaded hole two is formed at the bottom of the hemispherical head post;

[0047] When the assembled parts are in the assembled state, the first threaded hole and the second threaded hole are located on the same vertical line.

[0048] The technical effect of adopting the above-mentioned further solution is that the bolts can be screwed into the first threaded hole and the second threaded hole to achieve the effect of reinforcing the first and second keels.

[0049] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0050] 1. This utility model achieves assembly by manually pulling the hollow column to the surface of the hemispherical head column. Under the compression of the hemispherical head, spring two reaches a compressed state. When the hemispherical head is fully inside the hollow column, spring two lifts the beveled block, limiting the hemispherical head column. At this point, bolts are manually screwed into threaded holes one and two to fix the keel one and keel two. When removal is needed, first unscrew the bolt in threaded hole one, then pull the hollow column towards the diamond ring again. When the hollow column covers the diamond ring, pulling the hollow column back causes the beveled block to press the diamond ring tightly against the hemispherical head of the hemispherical head column. At this point, the surfaces of both form an arc, causing the beveled block to be squeezed back into slot one, thus allowing the hollow column to be removed and separated. This design allows keel one and keel two to be assembled simply by manual pulling, with bolts added for fixation, simplifying the assembly process.

[0051] 2. In this utility model, after separating keel one and keel two, the hexagonal bolts need to be manually unscrewed. The disassembly rings on both sides separate from keel one and keel two respectively. At this time, the rotating block also loses the support of the support rod and can rotate around the axis between the rectangular block and the rotating block. This solution achieves the effect of folding the assembled parts on both sides towards the keel by removing the bolts, further reducing space occupation and increasing carrying efficiency.

Detailed Implementation

[0060] 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.

[0061] Example 1:

[0062] Please see Figures 1-6 This embodiment provides a quick-assembly keel for greenhouses that can be folded and retracted. The specific concept is as follows:

[0063] A quick-assembly greenhouse keel includes keel one 1 and keel two 101. The quick-assembly greenhouse keel also includes two rectangular blocks 102 and two folding pieces.

[0064] The two rectangular blocks 102 are fixedly installed on one side of the keel 1 and keel 2 101 by welding, respectively.

[0065] The two folding components that need to be added are respectively installed on the rectangular block 102.

[0066] In addition, the two folding pieces can rotate around the internal pivot of the rectangular block 102 to reduce space occupation when carried.

[0067] As examples, the folding component in this embodiment includes: a rotating block 103, a retaining ring 104, a disassembly ring 106, a support rod 105, and a hexagonal bolt 107.

[0068] The rotating block 103, which plays a rotating role, is rotatably mounted on one side of the rectangular block 102 via a rotating shaft.

[0069] The fixing ring 104, which plays a fixing role, is fixedly installed at the bottom of the rotating block 103 by welding.

[0070] The disassembly ring 106, which plays an auxiliary role, is embedded in the keel 2 101.

[0071] The support rod 105, which serves as a connector, is connected between the fixing ring 104 and the disassembly ring 106.

[0072] It should be noted that the support rod 105 is rotatably connected to the fixing ring 104, and is fixedly connected to the disassembly ring 106.

[0073] The hexagonal bolts 107 that need to be installed are embedded in the disassembly ring 106.

[0074] In addition, hex bolt 107 penetrates through keel 2 101.

[0075] In this embodiment, after separating the first keel 1 and the second keel 101, the hex bolts 107 can be unscrewed with the help of tools so that the disassembly rings 106 embedded in the first keel 1 and the second keel 101 can be separated from the body. At this time, the rotating blocks 103 on both sides lose the support of the support rods 105. In this state, the rotating blocks 103 can rotate around the axis.

[0076] Example 2:

[0077] Please see Figures 1-6 Based on Example 1, this example provides a quick-assembly and quick-connect greenhouse keel, the specific concept of which is as follows:

[0078] The quick-assembly greenhouse keel also includes: splicing components, threaded hole 1 3 and threaded hole 2 301.

[0079] The assembled component is installed between two rectangular blocks 102.

[0080] It should be noted that the splicing components can move from both ends toward the middle along the horizontal line to splice and fix keel 1 and keel 2 101.

[0081] Among them, the threaded hole 3, which plays an auxiliary role, is opened at the bottom of the hollow column 202.

[0082] Among them, the auxiliary threaded hole 301 is opened at the bottom of the hemispherical head post 207.

[0083] It should be noted that when the assembled parts are in the assembled state, threaded hole 3 and threaded hole 301 can be located on the same vertical line.

[0084] As examples, the assembly in this embodiment includes: a fixed tube 2, a sliding column 201, a hollow column 202, two springs 203, two slots 204, two springs 205, a hemispherical head column 207, a rhomboid ring 208, and a tube wall 209.

[0085] The fixing tube 2, which plays an auxiliary role, is installed on one side of the rotating block 103.

[0086] It should be noted that the fixed tube 2 needs to be fitted with a soft rubber shell to protect the internal structure while ensuring the streamlined appearance. The internal structure is not shown in the figure. This material is existing technology and will not be described in detail here.

[0087] The sliding column 201, which serves as a connector, is embedded in the fixed tube 2.

[0088] It should be noted that the sliding column 201 can slide horizontally within the fixed tube 2.

[0089] The hollow column 202, which is used for assembly, is installed on one side of the sliding column 201.

[0090] Among them, two springs 203, which play an elastic role, are installed on one side of the fixed tube 2.

[0091] In addition, the other side of the two springs 203 is connected to the hollow column 202.

[0092] Among them, the two slots 204, which play an auxiliary role, are opened on the inner wall of the hollow column 202.

[0093] Among them, two springs 205, which play an elastic role, are respectively installed in two slots 204, and beveled blocks 206 are respectively installed on the other side of the two springs 205.

[0094] It should be noted that a limiting ring is provided at the opening of slot 204, and a limiting plate is also provided at the bottom of the bevel block 206 to ensure that the bevel block 206 will not be ejected from slot 204 by spring 205. The internal structure is shown in the figure and is not shown.

[0095] Among them, the hemispherical head column 207, which is used for the initial assembly, is installed on one side of the rotating block 103 connected to the keel 1.

[0096] Among them, the rhomboid ring 208, which plays an auxiliary role, is fitted on the hemispherical head post 207.

[0097] The pipe wall 209 is embedded in the rotating block 103 connected to the keel 1.

[0098] It should be noted that the tube wall 209 can slide inside the rotating block 103 and is connected to the inner wall of the rotating block 103 by a spring. The internal structure is shown in the figure and is not shown.

[0099] In addition, the rhomboid ring 208 can move in a straight line on the surface of the hemispherical head post 207.

[0100] In this embodiment, under manual pulling, the hollow column 202 can cover the surface of the hemispherical head column 207 to achieve the purpose of splicing. At the same time, under the compression of the hemispherical head shape of the hemispherical head column 207, the second spring 205 is compressed. When the hemispherical head of the hemispherical head column 207 is completely inserted into the hollow column 202, the second spring 205 controls the bevel block 206 to return to its original position, thereby fixing the hemispherical head column 207. At this time, the bolt is manually screwed into the threaded hole 3 and the threaded hole 301 to achieve fixation. The purpose of keel 1 and keel 2 101 is that when it needs to be removed, first unscrew the bolt in threaded hole 3, then pull the hollow column 202 towards the rhombus ring 208 again. When the hollow column 202 covers the rhombus ring 208, pull the hollow column 202 back in the opposite direction. The beveled block 206 drives the rhombus ring 208 to stick to the hemispherical head of the hemispherical column 207. At this time, the surfaces of the two form an arc surface, so that the beveled block 206 is squeezed back into the slot 204, thereby removing the hollow column 202 to achieve the separation effect.

[0101] Working principle:

[0102] When it is necessary to assemble keel 1 and keel 2 101, manually control the hollow column 202 so that it fits onto the hemispherical head column 207. Due to the hemispherical shape of one end of the hemispherical head column 207, it will push open the two beveled blocks 206 and compress the two springs 205. When the hemispherical shape of the hemispherical head column 207 has completely passed through the two beveled blocks 206, the two springs 205 will use their elasticity to spring the two beveled blocks 206 back to their original positions. At this time, threaded hole 3 and threaded hole 301 are on the same vertical line. Manually screw in the bolt to fix the splicing of keel 1 and keel 2 101.

[0103] When it is necessary to remove keel 1 and keel 2 101, remove the bolts from threaded hole 3 and threaded hole 301. Then, manually pull the hollow column 202 toward the rhombus ring 208. The rhombus ring 208 uses its shape to push open the two beveled blocks 206. When the rhombus ring 208 is behind the two beveled blocks 206, pull the hollow column 202 in the opposite direction. At this time, the two beveled blocks 206 drive the rhombus ring 208 to slide toward the hemisphere of the hemispherical head column 207. When the rhombus ring 208 and one end of the hemispherical head column 207 are in contact, an arc surface will be formed. Press the two beveled blocks 206 again to remove the hollow column 202 from the hemispherical head column 207.

[0104] After removal, when it is necessary to carry the keel of the quick-assembly greenhouse, manually tighten the hex bolt 107. When the hex bolt 107 is disengaged from the disassembly ring 106, the disassembly ring 106 can be removed. At this time, the support rod 105 drives the rotating block 103 to rotate. The rotating block 103 can drive the assembled parts to make a circular motion around the axis of rotation. At this time, the keel 1 and keel 2 101 are folded, which facilitates the carrying process.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art.
