Description

Technical Field

[0001] This application relates to the field of greenhouse technology, and in particular to a greenhouse frame structure. Background Technology

[0002] Greenhouses, as agricultural facilities that can control environmental conditions such as temperature, humidity, and light, are widely used in the cultivation and production of crops such as vegetables, flowers, and seedlings. The skeletal structure is the core component of a greenhouse, and its performance directly determines the stability, disaster resistance, and service life of the greenhouse.

[0003] In existing technologies, greenhouse frames mostly adopt an integrated structure. To adapt to the span requirements of greenhouses, the overall size of the frame is relatively long. This integrated structure has obvious drawbacks in practical applications: During the processing, the ultra-long components require extremely high stroke and precision from bending, welding, and other equipment, and are prone to deformation due to uneven stress, increasing processing difficulty and scrap rate; During the installation stage, due to the large weight and length of the components, heavy lifting equipment such as cranes must be used for hoisting and positioning, which not only increases equipment rental costs but is also affected by factors such as site flatness and space limitations, resulting in cumbersome and inefficient installation operations. Therefore, a greenhouse frame structure is proposed to solve the above problems. Utility Model Content

[0010] Preferably, a plug is fixedly connected to the outer wall of the end of the first arc-shaped rod facing the second arc-shaped rod. The plug is inserted into the interior of the second arc-shaped rod. A slot is provided on the bottom outer wall of the plug. The end of the plug located inside the second arc-shaped rod is adapted to and engaged with the slot. The two springs are respectively sleeved on the outer walls of the two fixed rods. The springs are located between the movable block and the fixed frame.

[0011] Preferably, the outer wall of the fixed cylinder is equipped with an adjustment mechanism for adjusting the height of the screw, which includes a bearing and a nut.

[0015] Preferably, a positioning block one is fixedly connected to the outer wall above the end of the first arc-shaped rod facing the second arc-shaped rod, and a positioning block two is fixedly connected to the outer wall above the end of the second arc-shaped rod facing the first arc-shaped rod. Multiple positioning rods are fixedly connected to the outer wall of the positioning block one, and multiple positioning holes are opened on the outer wall of the positioning block two.

[0016] In summary, this application includes the following beneficial technical effects:

Detailed Implementation

[0024] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0025] This application discloses a greenhouse frame structure. (Refer to...) Figure 1-4 A greenhouse frame structure includes two telescopic rod assemblies 1, an arc-shaped rod assembly 2, two connectors 3, and two guide rails 4. The components work together to form the main support structure of the greenhouse frame.

[0026] The telescopic rod assembly 1 is a telescopic and adjustable vertical support component, which includes a fixed cylinder 101 and a screw 102. The fixed cylinder 101 is a hollow columnar structure with openings at both the top and bottom. The rod part of the screw 102 is adapted to be inserted into the interior of the fixed cylinder 101, and the screw 102 can slide up and down along the axis of the fixed cylinder 101 to realize the adjustment of the overall length of the telescopic rod assembly 1.

[0027] The arc-shaped rod assembly 2 is an arc-shaped load-bearing component for the top of the greenhouse. It includes a first arc-shaped rod 21 and a second arc-shaped rod 22. Both the first arc-shaped rod 21 and the second arc-shaped rod 22 are arc-shaped rod structures. They are symmetrically arranged and spliced ​​together to form a complete top arc-shaped support. The bottom end of the first arc-shaped rod 21 is connected to the top end of one of the screws 102 by a threaded connection. The bottom end of the second arc-shaped rod 22 is also connected to the top end of the other screw 102 by a threaded connection. The arc-shaped rod assembly 2 and the telescopic rod assembly 1 can be detachably fixed through the threaded connection. At the same time, the opposite ends of the first arc-shaped rod 21 and the second arc-shaped rod 22 can be quickly spliced ​​and fixed through a quick-connect mechanism.

[0028] Two connectors 3 are respectively installed at the bottom ends of the two fixed cylinders 101 to connect the fixed cylinders 101 and the guide rail 4. The connector 3 includes a movable slider 301 and two connecting blocks 302. The movable slider 301 is a block structure adapted to the guide rail 4, and the two connecting blocks 302 are symmetrically arranged plate structures. The two are fixed to the top outer wall of the movable slider 301 by welding, and an installation gap is formed between the two connecting blocks 302 to fit the bottom end of the fixed cylinder 101. The bottom end of the fixed cylinder 101 is embedded in the installation gap, and the fixed cylinder 101 and the connector 3 are fixedly connected by bolts passing through the corresponding holes of the connecting blocks 302 and the fixed cylinder 101.

[0029] The inner wall of the movable slider 301 is adapted to the outer wall of the guide rail 4. The movable slider 301 is sleeved on the outer wall of the guide rail 4 and can slide along the length of the guide rail 4, thereby realizing the horizontal position adjustment of the entire skeleton structure.

[0030] Further, see Figure 2 As shown, the quick-connect mechanism is used to achieve rapid docking and separation of the first arc-shaped rod 21 and the second arc-shaped rod 22. It includes a fixed frame 203, a movable block 204, a locking block 205, and two springs 207. The fixed frame 203 is an L-shaped frame structure, which is connected to the bottom outer wall of the second arc-shaped rod 22 by welding or bolting. The open end of the fixed frame 203 faces upward. A fixed rod 206 is fixedly connected to each of the two top sides of the fixed frame 203. The two fixed rods 206 are parallel to each other and perpendicular to the top plane of the fixed frame 203. The movable block 204 is a rectangular block. The structure has sliding holes at both ends that are adapted to the fixed rods 206. The movable block 204 is sleeved on the outer wall of the two fixed rods 206 through the sliding holes and can slide up and down along the axis of the fixed rods 206. The locking block 205 is a columnar or block-shaped structure, and its bottom end is fixedly connected to the outer wall of the top middle section of the movable block 204 by welding or integral molding. The corresponding position of the second arc-shaped rod 22 has a through hole adapted to the locking block 205. The top end of the locking block 205 extends through the through hole into the interior of the second arc-shaped rod 22 for cooperating with the corresponding structure of the first arc-shaped rod 21 to achieve locking and fixing.

[0031] Furthermore, an insert block 201 is fixedly connected to the outer wall of the end of the first arc-shaped rod 21 facing the second arc-shaped rod 22. The insert block 201 is a block-shaped or columnar structure adapted to the inner cavity of the end of the second arc-shaped rod 22. The end of the second arc-shaped rod 22 facing the first arc-shaped rod 21 is an open structure. The insert block 201 can be adapted to be inserted into the inner cavity of the end of the second arc-shaped rod 22, realizing the initial insertion and positioning of the first arc-shaped rod 21 and the second arc-shaped rod 22. A slot 202 is provided on the bottom outer wall of the insert block 201 corresponding to the position of the locking block 205. The slot 202 is a groove structure adapted to the top of the locking block 205. When the insert block 201 is inserted into the inner cavity of the second arc-shaped rod 22, the end of the locking block 205 located inside the second arc-shaped rod 22 can be adapted to be locked into the slot. Within 202, the first arc-shaped rod 21 and the second arc-shaped rod 22 are locked together. Two springs 207 are respectively sleeved on the outer walls of the two fixed rods 206, and the springs 207 are located between the top of the fixed frame 203 and the bottom of the movable block 204. The top of the spring 207 abuts against the bottom outer wall of the movable block 204, and the bottom of the spring 207 abuts against the top outer wall of the fixed frame 203. In its natural state, the spring 207 is in a stretched or compressed state, providing an upward elastic force to the movable block 204, so that the locking block 205 is kept in the locking groove 202. When it is necessary to separate the first arc-shaped rod 21 and the second arc-shaped rod 22, the movable block 204 is pulled down to compress the spring 207, so that the locking block 205 is disengaged from the locking groove 202.

[0032] Further, see Figure 4 As shown, an adjustment mechanism for adjusting the height of the screw 102 is installed on the outer wall of the top end of the fixed cylinder 101. This adjustment mechanism can drive the screw 102 to move up and down along the axial direction of the fixed cylinder 101, thereby adjusting the overall height of the telescopic rod assembly 1. The adjustment mechanism includes a bearing 104 and a nut 105. The bearing 104 is a deep groove ball bearing or other commonly used bearing structure. The outer ring of the bearing 104 is fixedly connected to the inner or outer wall of the top end of the fixed cylinder 101 by interference fit or snap-fit. The nut 105 is an internally threaded nut adapted to the screw 102. The outer wall of the nut 105 is fixedly connected to the inner ring of the bearing 104 by interference fit or welding. The rod body of the screw 102 passes through the nut 105 and is threadedly connected to the nut 105. When the nut 105 is rotated, since the outer ring of the bearing 104 is fixed, the inner ring can rotate with the nut 105. Through threaded transmission, the screw 102 is driven to slide up and down along the axial direction of the fixed cylinder 101, thereby realizing height adjustment.

[0033] Furthermore, a limiting slider 103 is fixedly connected to the bottom end of the screw 102. The limiting slider 103 is a block structure adapted to the inner cavity of the fixed cylinder 101. Its outer diameter is slightly smaller than the inner diameter of the fixed cylinder 101, and its outer circumferential wall has multiple protrusions. The limiting slider 103 slides in cooperation with the inner wall of the fixed cylinder 101. When the screw 102 slides up and down along the fixed cylinder 101, the limiting slider 103 slides synchronously along the inner wall of the fixed cylinder 101. Through the limiting cooperation between the limiting slider 103 and the top of the fixed cylinder 101, the screw 102 can be prevented from completely coming out of the inside of the fixed cylinder 101, thus playing a limiting protection role. In addition, the multiple protrusions on the outer circumferential wall of the limiting slider 103 can prevent the screw 102 from being rotated by the rotation of the nut 105.

[0034] Further, see Figure 2 As shown, a pull rod 208 is fixedly connected to the outer wall of the bottom middle section of the movable block 204. The pull rod 208 is a rod-shaped structure, and its top end is fixed to the bottom of the movable block 204 by welding or threaded connection. A through hole adapted to the pull rod 208 is opened at the corresponding position of the fixed frame 203. The bottom end of the pull rod 208 passes through the through hole and extends to the bottom of the fixed frame 203. The operator can pull the pull rod 208 to drive the movable block 204 to slide up and down along the fixed rod 206, thereby controlling the lifting and lowering of the locking block 205, which facilitates the operation of the quick-connect mechanism to realize the splicing or separation of the first arc rod 21 and the second arc rod 22.

[0035] Further, see Figure 3 and Figure 4 As shown, a pin 303 is inserted into each of the two outer walls of the movable slider 301. The two pins 303 are symmetrically arranged along the axis of the movable slider 301. The pin 303 is a columnar structure, with one end being a conical or arc-shaped part for easy insertion, and the other end having a stop or cap to prevent it from falling off. The guide rail 4 is a long strip structure, with multiple adjustment holes 401 evenly spaced along its length on its outer wall. The adjustment holes 401 are through holes that fit the pins 303. When the movable slider 301 slides along the guide rail 4 to the target position, the pins 303 are passed through the corresponding holes of the movable slider 301 and inserted into the adjustment holes 401 of the guide rail 4, thereby fixing the movable slider 301 to the guide rail 4 and preventing the movable slider 301 from sliding during use.

[0036] Further, see Figure 2As shown, a positioning block 5 is connected to the outer wall above the end of the first arc-shaped rod 21 facing the second arc-shaped rod 22 by welding or bolting. The positioning block 5 is an arc-shaped block structure. Multiple positioning rods 51 are fixedly connected to the outer wall of the side of the positioning block 5 facing the second arc-shaped rod 22. The positioning rods 51 are columnar structures and are evenly distributed along the length of the positioning block 5. A positioning block 6 is fixedly connected to the outer wall above the end of the second arc-shaped rod 22 facing the first arc-shaped rod 21 at the position corresponding to the positioning block 5. The positioning block 6 is... The positioning block 5 is adapted to an arc-shaped block structure. The positioning block 6 has multiple positioning holes 61 on the outer wall of one side facing the first arc-shaped rod 21, corresponding to the positions of multiple positioning rods 51. The positioning holes 61 are through holes adapted to the positioning rods 51. When the first arc-shaped rod 21 and the second arc-shaped rod 22 are spliced ​​through the quick-connect mechanism, the multiple positioning rods 51 can be inserted into the inner wall of the multiple positioning holes 61 one by one, further enhancing the positioning accuracy and connection stability at the splicing point of the first arc-shaped rod 21 and the second arc-shaped rod 22, and preventing relative rotation or offset after splicing.

[0037] The implementation principle of a greenhouse frame structure according to this application embodiment is as follows: the telescopic rod assembly 1 can be raised and lowered through an adjustment mechanism. During installation, the height is lowered to facilitate the docking operation of the arc-shaped rod assembly 2. After installation, it is raised to the designed height to form a stable vertical support. Its limiting slider 103 can prevent the screw 102 from coming out. The arc-shaped rod assembly 2, after being spliced ​​by the first arc-shaped rod 21 and the second arc-shaped rod 22, forms the load-bearing frame of the greenhouse top, providing top support for the greenhouse body. The quick-connect mechanism is achieved through the pull rod 208, the movable block 204, the locking block 205, and the spring. The cooperation of 207 enables the rapid splicing and disassembly of the arc-shaped rod assembly 2. The positioning rod 51 and the positioning hole 61 can also improve the stability after splicing. The connector 3 serves to connect the telescopic rod assembly 1 and the guide rail 4. The position of the movable slider 301 can be fixed by the pin 303 to prevent slippage. The guide rail 4 provides a sliding track for the movable slider 301 of the connector 3. The horizontal spacing of the telescopic rod assembly 1 can be adjusted by the sliding of the movable slider 301 to adapt to different greenhouse span requirements. The adjustment hole 401 is used to cooperate with the pin 303 to achieve positioning and fixation.
