[0001] This utility model relates to the field of greenhouse roof window technology, and in particular to an installation structure for a drive shaft of a greenhouse and a greenhouse. Background Technology

[0002] In the greenhouse roof, the windows are opened and closed by a drive shaft. This drive shaft is horizontally mounted on the mounting structure and can rotate relative to the structure. A transmission gear is mounted on the drive shaft, meshing with a transmission rack, and the window sash is hinged to one end of the transmission rack. A drive motor drives the drive shaft to rotate, and the window opens and closes under the transmission action of the gear and rack.

[0003] The existing drive shaft mounting structure includes an O-ring and a fixing plate. After the O-ring is attached to the arch rod, the fixing plate is placed at the bottom of the O-ring, and the O-ring and fixing plate are locked together with bolts. Finally, the O-ring is fixed with self-tapping screws. The fixing plate has a through hole, through which the drive shaft passes. The fixing plate supports the drive shaft 002, and the drive shaft can rotate within the through hole of the fixing plate under the drive of the motor.

[0004] After the existing mounting structure is installed and fixed to the arch rod, the fixing plate of the mounting structure is difficult to keep stable when the drive shaft rotates and is prone to swinging. This may cause the fixing plate to jam with the drive shaft and damage the motor. Improvements are needed to address this issue. Utility Model Content

[0005] The purpose of this utility model is to propose an installation structure for the drive shaft of a greenhouse, in which the fixed plate installed between the drive shaft and the arch rod can maintain a stable position and the drive shaft is not easily jammed during rotation.

[0006] This utility model proposes an installation structure for a drive shaft of a greenhouse. The drive shaft is installed on the arch of the greenhouse and includes a fixing plate, several arc-shaped clamps, several fixing parts, and several locking parts. The fixing plate has a through hole for the drive shaft to pass through. The arc-shaped clamps include a clamping part and a pair of fixing parts, with the two fixing parts located on both sides of the clamping part. The clamping part and the fixing plate enclose the arch. The fixing parts fix the fixing plate and the fixing parts together, and the locking parts lock the clamping part and the arch.

[0007] Preferably, the fastener includes a bolt, a washer, and a nut. A first fixing hole is formed through the surface of the fixing part, and a second fixing hole is formed through the surface of the fixing plate. The bolt passes through the first fixing hole, the second fixing hole, and the washer in sequence, and is locked and fixed with the nut.

[0008] Preferably, a spring is provided between the washer and the nut.

[0009] Preferably, the surface of the fixing part is provided with a receiving groove, the first fixing hole is located in the receiving groove, and the head of the bolt is embedded in the receiving groove.

[0010] Preferably, the locking element is a screw, and a screw hole is formed on the surface of the clamp part. The screw is threaded into the screw hole and is threadedly connected and fixed to the arch rod.

[0011] Preferably, two arc-shaped clamps are provided, and after the two arc-shaped clamps are fixed on the fixing plate, they are kept parallel to each other.

[0012] Preferably, both the fixing plate and the arc-shaped clamp are made of carbon steel.

[0013] A greenhouse includes an installation structure, a drive shaft, a frame, an arch, and an outward-opening window. The arch is located on the frame. The outward-opening window includes a window sash, a drive motor, a transmission gear, and a transmission rack. The transmission gear is fixedly mounted on the drive shaft. One end of the transmission rack is hinged to the window sash, and the transmission rack meshes with the transmission gear. The drive motor drives the drive shaft to rotate.

[0025] To make the technical problem to be solved, the technical solution and the beneficial effects of this utility model clearer and more understandable, the following description is provided in conjunction with the appendix. Figure 1-7 The present invention will be further described in detail below with reference to the embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention and are not intended to limit the present invention.

[0026] Reference Figures 1-5 A greenhouse includes an installation structure 3, a drive shaft 2, a frame 8, an arch 1, and an outward-opening window 9. The arch 1 is located on the frame 8, and the installation structure 3 is fixedly installed on the arch 1 to support the drive shaft 2. The installation structure 3 includes a fixing plate 4, two arc-shaped clamps 5, two pairs of fixing parts 6, and two locking parts 7. A through hole 41 is formed on the surface of the fixing plate 4. After the installation structure 3 is fixed, the drive shaft 2 passes through the through hole 41 on the surface of the fixing plate 4, thereby supporting the drive shaft 2 through the installation structure 3. The arc-shaped clamps 5 consist of a clamp part 51 and a pair of fixing parts 52. The two fixing parts 52 are located on both sides of the clamp part 51. During installation, the clamp part 51 is wrapped around the arch 1, and the fixing parts 52 on both sides of the clamp part 51 abut against the surface of the fixing plate 4. The fixing parts 52 of the arc-shaped clamps 5 are locked and fixed to the fixing plate 4 by the fixing parts 6.

[0027] The outward-opening window 9 includes a window sash 91, a drive motor 92 (not shown in the figure), a transmission gear 93, and a transmission rack 94. The transmission gear 93 is fixedly mounted on the drive shaft 2. The transmission rack 94 meshes with one side of the transmission gear 93, and one end of the transmission rack 94 is hinged to the window sash 91. The rotating shaft of the drive motor 92 is fixed to the drive shaft 2, and the drive motor 92 drives the drive shaft 2 to rotate, thereby driving the transmission rack 94 through the transmission gear 93, thus realizing the flipping of the window sash 91. During the rotation of the drive shaft 2 within the through hole 41 of the fixing plate 4, the fixing plate 4 can maintain a stable position and will not wobble. Therefore, the drive shaft 2 is not prone to jamming with the fixing plate 4 during rotation, ensuring smooth rotation of the drive shaft 2.

[0028] Reference Figure 6 and Figure 7 The fastener 6 includes a bolt 61, a washer 62, and a nut 63. Correspondingly, a first fixing hole 521 is formed through the surface of the fixing part 52, and a second fixing hole 42 is formed through the surface of the fixing plate 4. The bolt 61 is passed through the first fixing hole 521 of the fixing part 52 and the second fixing hole 42 of the fixing plate 4 in sequence. Then, the washer 62 is put on the bolt 61 and abuts against the surface of the fixing plate 4. The nut 63 is screwed on the bolt 61 and abuts against the washer 62, thereby locking the fixing part 52 of the arc-shaped clamp 5 to the fixing plate 4. To ensure a more secure fixation between the fixing part 52 and the fixing plate 4, a spring 64 is provided between the washer 62 and the nut 63. The spring 64 is also fitted onto the bolt 61. As the nut 63 is screwed onto the bolt, the two ends of the spring 64 abut against the washer 62 and the nut 63 respectively. The spring 64 increases the internal tightening force of the fixing part 6. Thus, after the fixing part 6 fixes the fixing plate 4 and the clamp part 51, loosening between the fixing plate 4 and the arc-shaped clamp 5 can be avoided.

[0029] To further enhance the tightness between the fixing member 6 and the arc-shaped clamp 5 and the fixing plate 4, a receiving groove 522 is formed on the surface of the fixing part 52, so that the first fixing hole 521 is located in the receiving groove 522. After the bolt 61 is passed through the first fixing hole 521, the second fixing hole 42, the washer 62 and the spring 64, and locked with the nut 63, the head 611 of the bolt 61 is engaged in the receiving groove 522 of the fixing part 52. The receiving groove 522 on the surface of the fixing part 52 of the arc-shaped clamp 5 allows the bolt 61 to be locked in a thinner part of the fixing part 52, thereby enhancing the tightness of the connection between the fixing part 52 and the fixing plate 4, and further preventing loosening between the fixing plate 4 and the fixing part 52.

[0030] Reference Figure 4 and Figure 6After the two arc-shaped clamps 5 are installed and fixed between the fixing plate 4 by two pairs of fixing parts 6, the two arc-shaped clamps 5 are made parallel to each other. The two arc-shaped clamps 5 are installed on the arch rod 1 by cooperating with the fixing plate 4, thereby making the installation structure 3 more firmly installed on the arch rod 1. In order to prevent the installation structure 3 from rotating relative to the arch rod 1, which would cause the position angle of the installation structure 3 to be skewed and cause the drive shaft 2 to collide with the inner wall of the through hole 41 during rotation, the locking part 7 is set as a screw, and a screw hole 511 is formed on the surface of the clamp part 51 of the arc-shaped clamp 5. The screw is threaded into the screw hole 511 of the clamp part 51 and inserted into the arch rod 1 to lock it, thereby making the fixation between the installation structure 3 and the arch rod 1 more secure.

[0031] Both the fixing plate 4 and the arc-shaped clamp 5 are made of carbon steel. The carbon steel material provides higher structural strength and better toughness, thus offering greater load-bearing capacity for the drive shaft 2. The drive shaft 2 is driven by a motor to rotate, thereby opening and closing the window. During rotation, the drive shaft 2 is prone to colliding with the inner wall of the through hole 41. However, due to the good toughness of the carbon steel arc-shaped clamp 5 and the carbon steel fixing plate 4, they are less likely to fracture brittlely upon impact from the drive shaft 2. Furthermore, the carbon steel material used for the fixing plate 4 and the arc-shaped clamp 5 also offers advantages such as ease of processing and welding, and low cost.

[0032] The specific implementation principle of this application embodiment is as follows: When the mounting structure 3 is required to support the drive shaft 2, the arc-shaped clamp 5 is mounted on the arch rod 1. Both fixing parts 52 of the arc-shaped clamp 5 abut against the fixing plate 4, and the first fixing hole 521 on the fixing part 52 corresponds to the second fixing hole 42 on the fixing plate 4. The bolt 61 is passed through the first fixing hole 521, the second fixing hole 42 and the washer 62 in sequence, and the spring 64 is sleeved on the bolt 61, so that one end of the spring 64 abuts against the washer 62. A nut 63 is threaded onto the bolt 61, so that the nut 63 abuts against the other end of the spring 64. As the nut 63 is further rotated to compress the spring 64, the arc-shaped clamp 5 and the fixing plate 4 are firmly installed. The setting of the spring 64 prevents the arc-shaped clamp 5 and the fixing plate 4 from loosening after installation, and improves the fastening force of the arc-shaped clamp 5 and the fixing plate 4 after installation.

[0033] A screw is threaded into the screw hole 511 of the clamp part 51, and the screw is further screwed into the interior of the arch rod 1 to lock it, thereby preventing relative rotation between the fixing plate 4 and the arch rod 1. The drive shaft 2 is inserted into the through hole 41 of the fixing plate 4, and the fixing plate 4 supports the drive shaft 2. Under the action of the drive motor 92, the drive shaft 2 rotates in the through hole 41 of the fixing plate 4, thereby driving the transmission rack 94 under the action of the transmission gear 93, thereby realizing the flipping of the window sash 91. The fixing plate 4 of this mounting structure 3 cooperates with the arc-shaped clamp 5 and is fixedly installed on the arch rod 1. After the fixing plate 4 is fixedly installed, it can maintain a stable position and will not wobble. When the drive shaft 2 hits the fixing plate 4 during installation, it avoids the fixing plate 4 from tilting and needing to be readjusted. In addition, the drive shaft 2 is not easy to jam with the fixing plate 4 during rotation.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, shall be protected by the present invention.
