Description

Technical Field

[0001] This utility model relates to the field of pipe connection technology, and in particular to a connection structure between longitudinal pipes and arch pipes in a greenhouse. Background Technology

[0002] When constructing a greenhouse, longitudinal pipes and arched pipes are two common components. Longitudinal pipes refer to the horizontal beams connecting the two side walls of the greenhouse, which are used to support the entire greenhouse structure and increase its stability and load-bearing capacity. Arched pipes refer to the arc-shaped pipes or rods located at the top of the greenhouse. They bend along the length of the greenhouse to form an arched structure. The arched pipes serve to support the roof covering material of the greenhouse and can also share some of the external pressure such as wind and snow pressure.

[0003] In practical use, longitudinal pipes are usually set inside the arch pipes, forming a cross shape with the arch pipes. Each longitudinal pipe needs to be connected to all the arch pipes to connect all the longitudinal pipes and arch pipes into a whole, improving the overall stability of the greenhouse. The connection between the longitudinal pipes and the arch pipes is usually achieved by binding with steel wire. The process of binding with steel wire is cumbersome, time-consuming and labor-intensive, and the steel wire is difficult to remove after it is firmly bound, which brings inconvenience to the user in adjusting the position of the longitudinal pipes during the construction process. Utility Model Content

[0004] This utility model aims to provide a connection structure for the longitudinal pipe and arch pipe of a greenhouse, in order to solve the problems mentioned in the background art. In this solution, the arch pipe clamping block can be quickly fixed to any position on the arch pipe by utilizing its own deformation. The longitudinal pipe can be quickly fixed to the arch pipe clamping block by inserting it through a pair of longitudinal pipe clamping blocks. By tightening the first screw and the second screw, the arch pipe and the longitudinal pipe can be further fixed, thereby quickly achieving the connection between the arch pipe and the longitudinal pipe. The operation is simple and quick, improving the greenhouse construction speed. By loosening the first screw and the second screw, the position of the longitudinal pipe or the arch pipe clamping block can be adjusted without ensuring that the longitudinal pipe does not fall off the arch pipe. This allows users to optimize the greenhouse structure according to the actual situation without having to perform cumbersome installation and disassembly steps on the connecting parts, bringing convenience to users and improving the practicality of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A connection structure for a greenhouse longitudinal pipe and an arched pipe includes an arched pipe clamping block, a first screw, and a pair of longitudinal pipe clamping blocks. Each arched pipe clamping block has a baffle integrally formed on both sides of its bottom end. The pair of baffles are symmetrical, and each baffle has a limiting post integrally formed at one end away from the other. The inner cavity of the limiting post extends through the baffle. One of the limiting posts has a threaded groove engraved on its inner wall that matches the first screw. The bottom end of the baffle has a limiting groove. The longitudinal pipe clamping block includes a sleeve block, and the top of the sleeve block has a first pressing block integrally formed. The upper parts of both the first pressing block and the sleeve block are disposed within the inner cavity of the limiting groove. A second pressing block is disposed inside the limiting groove. The upper surface of the second pressing block is inclined, and the inclined surface of the second pressing block abuts against the first pressing block. The outer end of the baffle is threadedly connected to a second screw, one end of which extends into the inner cavity of the limiting groove and is rotatably connected to the second pressing block.

[0007] Preferably, the arched tube clamping block is configured as a hollow cylindrical structure with an open bottom end.

[0008] Preferably, the sleeve block is configured as a U-shaped structure, and the inner end of the sleeve block is provided with multiple anti-slip grooves.

[0009] Preferably, both ends of the sleeve block located in the inner cavity of the limiting groove are fixedly connected to sliders, and both ends of the inner wall of the limiting groove are provided with sliding grooves that match the anti-slip groove, and the sliders and sliding grooves are slidably connected.

[0010] Preferably, the end of the first extrusion block that abuts against the second extrusion block is configured as an inclined surface opposite to the inclination direction of the second extrusion block.

[0011] The beneficial effects of this technical solution compared to existing technologies are as follows:

[0012] In this design, the arch pipe clamping block can be quickly fixed to any position on the arch pipe by utilizing its own deformation. The longitudinal pipe can be quickly fixed to the arch pipe clamping block by inserting it through a pair of longitudinal pipe clamping blocks. By tightening the first and second screws, the arch pipe and longitudinal pipe can be further fixed, thus quickly connecting the arch pipe and longitudinal pipe. The operation is simple and quick, improving the greenhouse construction speed. By loosening the first and second screws, the position of the longitudinal pipe or arch pipe clamping block can be adjusted without the longitudinal pipe falling off the arch pipe. This allows users to optimize the greenhouse structure according to the actual situation without the need for cumbersome installation and disassembly steps of the connecting parts, bringing convenience to users and improving the practicality of the device.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments:

[0020] like Figure 1-5 The diagram illustrates a connection structure between a longitudinal pipe and an arched pipe in a greenhouse. It includes an arched pipe clamping block 1, a first screw 4, and a pair of longitudinal pipe clamping blocks 5. Both sides of the bottom end of the arched pipe clamping block 1 are integrally formed with baffles 2. The pair of baffles 2 are symmetrical, and each baffle 2 has a limiting post 3 integrally formed at one of its opposite ends. The inner cavity of the limiting post 3 penetrates through the baffle 2. One of the limiting posts 3 has a threaded groove on its inner wall that matches the first screw 4. A limiting groove 6 is provided at the bottom end of the baffle 2. The longitudinal pipe clamping blocks 5... The device includes a sleeve block 51, with a first extrusion block 52 integrally formed at the top of the sleeve block 51. The upper parts of the first extrusion block 52 and the sleeve block 51 are both disposed in the inner cavity of the limiting groove 6. A second extrusion block 9 is disposed inside the limiting groove 6. The upper surface of the second extrusion block 9 is set as an inclined surface, and the inclined surface of the second extrusion block 9 abuts against the first extrusion block 52. A second screw 7 is threadedly connected to the outer end of the baffle 2. One end of the second screw 7 extends into the inner cavity of the limiting groove 6 and is rotatably connected to the second extrusion block 9.

[0021] When building a greenhouse, longitudinal pipes and arch pipes are two common components. Longitudinal pipes are usually set inside the arch pipes and are arranged in a cross shape with the arch pipes. Each longitudinal pipe needs to be connected to all the arch pipes to connect all the longitudinal pipes and arch pipes into a whole, thereby improving the overall stability of the greenhouse.

[0022] In this solution, the user can pry the pair of baffles 2 apart, causing a slight deformation of the arch pipe clamping block 1, opening the bottom opening of the arch pipe clamping block 1. Then, the arch pipe clamping block 1 is fitted onto the arch pipe, positioning it at the point where the arch pipe and longitudinal pipe need to connect. At this point, the user releases the pair of baffles 2, and the arch pipe clamping block 1 returns to its original position and is pressed against the outer end of the arch pipe, temporarily fixing it in the current position. Next, the user inserts the longitudinal pipe through the pair of fitting blocks 51 and rotates the pair of second screws 7, causing the second screws 7 to move into the limiting groove 6. The movement of the second screws 7 drives the second pressing block 9 to move within the limiting groove 6. The inclined surface of the second pressing block 9 presses against the first pressing block 52, pushing the longitudinal pipe clamping block 5 upwards, allowing the fitting block 51 to gradually enter... In the inner cavity of the limiting groove 6, the longitudinal tube is ultimately squeezed between the inner wall of the sleeve block 51 and the bottom end of the baffle 2, thus fixing the longitudinal tube. Finally, the user inserts the first screw 4 through one of the limiting posts 3 and connects the first screw 4 to the other limiting post 3 by thread. Tightening the first screw 4 forces a pair of baffles 2 to move closer to each other, thereby causing the pair of baffles 2 to drive the arch tube clamping block 1 to retract inward, so that the arch tube clamping block 1 clamps the arch tube. With this setting, the arch tube and the longitudinal tube can be fixed quickly. After loosening the second screw 7 and the first screw 4, the longitudinal tube and the arch tube can still be fixed to a certain extent, while allowing the arch tube clamping block 1 and the longitudinal tube to move. Thus, the connection part can be adjusted at any time during the installation process without the need for cumbersome installation and disassembly steps.

[0023] The arch pipe clamping block 1 is a hollow cylindrical structure with an open bottom, and the sleeve block 51 is a U-shaped structure with multiple anti-slip grooves 54 on the inner end of the sleeve block 51.

[0024] In this scheme, the arch pipe clamping block 1 can be sleeved on any position of the arch pipe as needed. The U-shaped structure of the sleeve block 51 allows it to surround the longitudinal pipe, so that even if the longitudinal pipe is not fixed temporarily after being inserted into it, it will not fall off. The opening of multiple anti-slip grooves 54 can effectively enhance the friction between the sleeve block 51 and the longitudinal pipe, and improve the fixing effect of the sleeve block 51 on the longitudinal pipe.

[0025] The sleeve block 51 is fixedly connected to both ends of the inner cavity of the limiting groove 6 with sliders 53. The inner wall of the limiting groove 6 is provided with sliding grooves 8 that match the anti-slip groove 54 at both ends. The sliders 53 and sliding grooves 8 are slidably connected.

[0026] In this design, when the longitudinal tube clamping block 5 moves within the limiting groove 6, it can slide within the sliding groove 8 via the slider 53. This design can improve the stability of the longitudinal tube clamping block 5 during movement.

[0027] The end of the first extrusion block 52 that abuts against the second extrusion block 9 is set as an inclined surface opposite to the inclination direction of the second extrusion block 9.

[0028] In this scheme, the surfaces of the first extrusion block 52 and the second extrusion block 9 that press against each other are set as matching inclined surfaces, which can make the pushing of the second extrusion block 9 against the longitudinal tube clamping block 5 more efficient. This is because the extrusion process between two inclined surfaces is usually easier than the extrusion between vertical surfaces. Due to the slope of the inclined surface, the force applied vertically downward will be decomposed into two components: a component perpendicular to the inclined surface and a component parallel to the inclined surface. Only the component perpendicular to the inclined surface will cause extrusion, and this component is small, so the force required to be applied will be relatively small.

[0029] The specific implementation process is as follows:

[0030] In use, the user moves the pair of baffles 2 away from each other, causing a slight deformation of the arch pipe clamping block 1 and opening the bottom opening of the arch pipe clamping block 1. Then, the arch pipe clamping block 1 is fitted onto the arch pipe, positioning it at the point where the arch pipe and longitudinal pipe need to connect. The user then releases the pair of baffles 2, causing the arch pipe clamping block 1 to return to its original position and press against the outer end of the arch pipe, temporarily fixing it in the current position. Next, the user inserts the longitudinal pipe through the pair of fitting blocks 51 and rotates the pair of second screws 7, causing the second screws 7 to move into the limiting groove 6. The movement of the second screws 7 drives the second pressing block 9 to move within the limiting groove 6. The second pressing block 9, tilted towards the first pressing block 52, compresses and pushes the longitudinal pipe clamping block 5 upwards, causing the fitting block 51 to... Gradually entering the inner cavity of the limiting groove 6, the longitudinal tube is eventually squeezed between the inner wall of the sleeve block 51 and the bottom end of the baffle 2, thus fixing the longitudinal tube. Finally, the user inserts the first screw 4 through one of the limiting posts 3 and connects the first screw 4 to the other limiting post 3 by thread. Tightening the first screw 4 forces a pair of baffles 2 to move closer to each other, thereby causing the pair of baffles 2 to drive the arch tube clamping block 1 to retract inward, clamping the arch tube with the arch tube, thus fixing the arch tube and the longitudinal tube. When the user needs to adjust the position of the connector or the longitudinal tube and the arch tube, first loosen the second screw 7 and the first screw 4. At this time, the longitudinal tube and the arch tube can still be fixed to a certain extent, while allowing the arch tube clamping block 1 and the longitudinal tube to move.
