Description

Technical Field

[0001] The invention relates to the technical field of greenhouse ceiling frames, and in particular to a large-span assembled greenhouse ceiling frame. Background Art

[0002] Greenhouse is one of the important equipment in modern agriculture. It has the advantages of regulating temperature, humidity and light. It also has the functions of reducing pests and diseases, activating soil and improving soil quality, which greatly facilitates agricultural production. In the greenhouse, the roof frame of the greenhouse is one of the important components. It can keep the greenhouse stable, and the roof frame will affect the stability, heat preservation and light transmittance of the greenhouse.

[0003] For example, a greenhouse frame with publication number CN104813871B includes at least two film fixing beams, a driving device, a flexible part and a film dragging part for fixing a second film. Through the cooperation of the film dragging part with a simple structure, the flexible part and the fixing groove on the arc-shaped lower chord beam of the film fixing beam, the second film can be opened and folded under the drive of the driving device. At the same time, the second film is naturally bent and folded together under the drive of the film dragging part, thereby avoiding wear of the second film and ensuring that the service life of the film will not be reduced due to wear.

[0004] Another example is a frame structure of an agricultural greenhouse with a publication number of CN109892140B, which includes: a straight first and second unit frames including a frame outer surface facing the greenhouse cover and a frame inner surface facing the interior of the agricultural greenhouse; and a main connecting member connecting the first and second unit frames in a curved shape. The connecting member includes: a connecting plate having a shape in which a first edge facing the frame outer surface is longer than a second edge facing the frame inner surface; a first fastening bolt fastening one end of the connecting plate to the first unit frame; a second fastening bolt fastening the other end of the connecting plate to the second unit frame; and a reinforcing portion having a shape in which a center portion of the connecting plate from one end to the other end is protruding compared to an edge portion thereof.

[0005] Before use, a large number of disassembly and assembly tools are needed during the construction and disassembly of the greenhouse frame. However, the ceiling frame in the above application does not have a good disassembly and assembly structure when in use, which will affect the operator's work efficiency and bring unnecessary trouble to the operator.

[0006] In view of the above problems, it is urgent to carry out innovative design based on the original greenhouse roof frame. Summary of the invention

[0007] The purpose of the present invention is to provide a large-span assembled greenhouse ceiling frame to solve the problem proposed in the above background technology that the frame does not have a good disassembly and assembly structure, which will affect the operator's work efficiency and bring unnecessary troubles to the operator.

[0008] To achieve the above object, the present invention provides the following technical solution: a large-span assembled greenhouse ceiling frame, comprising a support frame, a support beam is provided inside the support frame, and the support frame is symmetrically distributed about the center of the support beam, and a movable groove is provided on the surface of the support frame; and further comprising: A card block, wherein the card block is movably arranged inside the movable groove, and a cross bar is fixedly connected to the inner wall of the movable groove; A stress-bearing rod is slidably arranged inside the support frame, and a placement groove is opened on the surface of the support frame, and a support beam is placed inside the placement groove.

[0009] Preferably, the surface of the support beam is provided with card slots, and the card slots are symmetrically distributed about the center of the support beam, and the support beams are distributed on the surface of the support frame at equal intervals, and the card slots correspond to the card blocks one by one.

[0010] Preferably, the upper surface of the block is inclined, and a first spring having an elastic reset function is fixedly connected to the back of the block, and the other side of the first spring is fixedly connected to the inner wall of the support frame.

[0011] Preferably, a side connecting rod is fixedly connected to the side surface of the clamping block, and the side connecting rod is penetrated by the cross rod, and two adjacent cross rods are arranged inside the side connecting rod.

[0012] Preferably, the stress-bearing rods are symmetrically distributed about the center of the placement slot, and the lower ends of the stress-bearing rods are fixedly connected to auxiliary plates.

[0013] Preferably, a lower connecting plate corresponding one-to-one to the auxiliary plates is fixedly connected to the lower surface of the supporting frame, and the lower connecting plate is an inverted "L" structure when viewed from the front.

[0014] Preferably, a second spring having an elastic reset function is fixedly connected to the upper surface of the lower connecting plate, and the other side of the second spring is fixedly connected to the lower surface of the auxiliary plate.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the large-span assembled greenhouse ceiling frame adopts a new structural design, the specific contents of which are as follows: (1) When docking the support beam of the large-span assembled greenhouse ceiling frame, the support beam is directly placed in the placement groove from top to bottom. At this time, the clamping block will move in the direction of squeezing the first spring. When the clamping block and the clamping groove are in the same horizontal direction, the clamping block will enter the clamping groove, that is, the support beam has been docked on the support frame. The docking process is simple and quick, and is convenient for the operator to use.

[0016] Furthermore, the clamping blocks and the clamping slots are symmetrically distributed on both sides of the support beam, thereby optimizing the clamping effect between the support beam and the support frame and improving stability.

[0017] (2) For the large-span assembled greenhouse ceiling frame, when the support beam needs to be removed, the operator can pull the side connecting rod, and then the side connecting rod drives the block to move, and finally the end of the block can be moved out of the slot. At this time, the support beam and the support frame are not in a locked state, and the operator can quickly remove the support beam, which is highly efficient.

[0018] Furthermore, during the movement of the side connecting rod, the cross bar enables the side connecting rod and the clamping block to move only in the horizontal direction, thereby ensuring the stability of the side connecting rod and the clamping block.

[0019] (3) In the process of connecting the support beams of the large-span assembled greenhouse ceiling frame, the stress-bearing rod will be squeezed by the support beams. At this time, the auxiliary plate and the lower connecting plate cooperate to keep the second spring in a squeezed state. When the support beam and the support frame are not in a locked state, the stress-bearing rod rises under the action of the second spring and the auxiliary plate. The stress-bearing rod can push the support beam to make it rise, which plays a role in assisting disassembly and facilitates the operator's disassembly work. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 6 The present invention provides the following technical solutions: Embodiment 1: By setting the card block 5 and the card slot 4, the support beam 2 can be quickly connected to the support frame 1, such as Figure 1-Figure 6 As shown: it includes a support frame 1, a support beam 2 is arranged in a clamping manner inside the support frame 1, and the support frame 1 is symmetrically distributed about the center of the support beam 2, and a movable groove 13 is opened on the surface of the support frame 1. It also includes a clamping block 5 and a force-bearing rod 9, the clamping block 5 is movably arranged inside the movable groove 13, and a cross bar 3 is fixedly connected to the inner wall of the movable groove 13, the force-bearing rod 9 is slidably arranged inside the support frame 1, and a placement groove 8 is opened on the surface of the support frame 1, and the support beam 2 is placed inside the placement groove 8.

[0024] A card slot 4 is provided on the surface of the support beam 2, and the card slots 4 are symmetrically distributed about the center of the support beam 2, and the support beam 2 is evenly distributed on the surface of the support frame 1, the card slots 4 correspond to the card blocks 5 one by one, the upper surface of the card block 5 is inclined, and the back of the card block 5 is fixedly connected to a first spring 7 that plays an elastic reset role, and the other side of the first spring 7 is fixedly connected to the inner wall of the support frame 1.

[0025] When docking the support beam 2, the end of the support beam 2 is placed from top to bottom into the placement groove 8. At this time, the lower surface of the support beam 2 will push the block 5 through the inclined surface of the block 5, so that the block 5 moves in the direction of squeezing the first spring 7. After the support beam 2 contacts the bottom of the placement groove 8, the groove 4 and the block 5 on the surface of the support beam 2 are in the same horizontal direction. At this time, the block 5 returns to its original position under the action of the first spring 7. At this time, the end of the block 5 enters into the inside of the groove 4, that is, the support beam 2 has been docked on the support frame 1. Thereafter, the other support beams 2 can be installed through the same operation. The installation process is simple and quick.

[0026] Embodiment 2: Different from Embodiment 1, the support beam 2 can be quickly disassembled, such as Figure 4 and Figure 5 As shown, a side connecting rod 6 is fixedly connected to the side of the clamping block 5 , and the side connecting rod 6 is penetrated by the cross bar 3 , and two adjacent cross bars 3 are arranged inside the side connecting rod 6 .

[0027] When the support beam 2 needs to be removed, the corresponding side connecting rod 6 can be pulled to make the side connecting rod 6 slide inside the movable groove 13. At this time, the side connecting rod 6 will drive the end of the block 5 to move out of the groove 4, and then the support beam 2 and the support frame 1 are in a non-engaged state. At this time, the operator can remove the support beam 2. During the movement of the side connecting rod 6, the cross bar 3 makes the side connecting rod 6 move only in the horizontal direction.

[0028] Embodiment 3: Different from Embodiment 2, the force-bearing rod 9 and the second spring 12 are provided to assist in disassembly, making it easier for the operator to disassemble the support beam 2.

[0029] During the docking process of the support beam 2, the force-bearing rod 9 will be squeezed by the support beam 2. At this time, the force-bearing rod 9 moves downward inside the support frame 1, and then the auxiliary plate 10 drops synchronously. At this time, the auxiliary plate 10 and the lower connecting plate 11 cooperate to make the second spring 12 always in a squeezed state. When the support beam 2 and the support frame 1 are in a non-engaged state, the force-bearing rod 9 rises under the action of the second spring 12 and the auxiliary plate 10. At this time, the force-bearing rod 9 can push the support beam 2 to make the support beam 2 rise, which plays a role of auxiliary disassembly and facilitates the operator's disassembly work.
