[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0028] like Figure 1-6 As shown, a keel assembly used in a greenhouse comprises:
[0029] A crossbeam 1 and an arch frame 2, wherein positioning blocks 11 are arranged in an array on the crossbeam 1;
[0030] The coupling body 3 has a beam connecting frame 31 fixedly disposed thereon, and a first sliding block 311 cooperating with a latch of the positioning block 11 is slidably disposed in the beam connecting frame 31;
[0031] The coupling body 3 also includes a clamping plate 33 and an elastic plate 35 , wherein the elastic plate 35 is located between the symmetrically arranged clamping plates 33 . The elastic plate 35 is pushed and deformed by the arch frame 2 to be a C-shaped structure that is clamped on the surface of the arch frame 2 .
[0032] Specifically, when connecting, the beam connecting frame 31 on the coupling body 3 is plugged into the positioning block 11 set on the beam 1, driving the first sliding block 311 symmetrically arranged in the beam connecting frame 31 to move relative to each other, so that the first sliding block 311 is plugged into the positioning block 11, thereby completing the installation and fixation of the coupling body 3, and realizing rapid positioning of the coupling body 3, without the need for staff to perform repeated measurements and positioning, thereby improving installation efficiency.
[0033] Furthermore, when installing the arch frame 2, it is only necessary to make the arch top of the arch frame 2 push the elastic plate 35. The elastic plate 35 is pushed and deformed by the arch frame 2 to form a C-shaped structure and clamped on the surface of the arch frame 2, thereby clamping and fixing the arch frame 2. The change of the elastic plate 35 is as follows: Figure 6 to Figure 4 As shown, it is convenient and quick, further improving the installation efficiency.
[0034] The second rubber pad 352 provided on the elastic plate 35 increases the friction damping with the arch frame 2 , thereby improving the fixation of the elastic plate 35 to the arch frame 2 and providing elastic protection to the arch frame 2 .
[0035] The first slide block 311 is connected to the first slide block 311 of the second end of the second end of the second end of the second end of the second end of the second end of the second end of the second end of the second end of the second end of the second end of the second end of the second end of the second end of the second end of the second end of the second end of the second end of the second end.
[0036] As a further embodiment of the present invention, it also includes a cylinder 36 fixedly arranged inside the coupling body 3, in which a piston plate 361 is slidably arranged.
[0037] Specifically, it also includes a connecting rod 351 fixedly set on the piston plate 361, which is fixedly connected to the top of the arc of the elastic plate 35. It also includes a first slide groove 313 symmetrically opened in the crossbeam connecting frame 31, which is connected to the cylinder 36 through the first air channel 312, and the first slider 311 is slidably set in the first slide groove 313. The card slot 111 of the crossbeam connecting frame 31 on the coupling body 3 is plugged and matched with the positioning block 11 set on the crossbeam 1 to achieve pre-fixation of the coupling body 3, and then the arch frame 2 is directly installed. It is only necessary to make the arch top of the arch frame 2 push the elastic plate 35. The elastic plate 35 is deformed by the arch frame 2 and is clamped on the surface of the arch frame 2 in a C-shaped structure. During the deformation of the elastic plate 35, the connecting rod 351 set at the top of the arc of the elastic plate 35 is driven to push the piston plate 361 to move in the cylinder 36, thereby squeezing the air in the cylinder 36 into the first The air in the air passage 312 enters the first slide groove 313 through the first air passage 312. As the air pressure in the first slide groove 313 increases, the first slider 311 is pushed to move and the first spring is stretched, so that the first slider 311 cooperates with the latch of the positioning block 11, thereby fixing the coupling body 3 on the beam 1, effectively preventing the coupling body 3 from moving on the beam 1 under the action of strong wind, and improving the stability of the connection. At the same time, no additional driving source is required to drive the first slider 311 to move, which further simplifies the structure and saves manufacturing costs.
[0038] As a further embodiment of the present invention, the present invention further comprises a support frame 32 symmetrically arranged on the crossbeam connecting frame 31 , on which an auxiliary support member 34 is fixedly arranged, and the auxiliary support member 34 is a U-shaped structure.
[0039] Specifically, the two sides of the arch frame 2 are located in the U-shaped groove of the auxiliary support member 34, so as to support the two sides of the arch top, and cooperate with the elastic plate 35 to provide multi-point support for the arch frame 2, effectively preventing the arch frame 2 from being deformed under the action of strong wind, effectively improving the overall support strength, and further providing elastic protection for the arch frame 2 through the first rubber pad 342 arranged in the U-shaped groove.
[0040] As a further embodiment of the present invention, it also includes a second sliding block 341 symmetrically arranged on the auxiliary support member 34 , which slides and docks to lock the arch frame 2 .
[0041] Specifically, the symmetrically arranged second sliders 341 are driven to move relative to each other, and the two second sliders 341 are made to abut against each other, thereby limiting the arch frame 2 in the U-shaped groove of the auxiliary support member 34, and cooperating with the elastic plate 35 to doubly lock the arch frame 2. When the elastic plate 35 loses its fixing effect on the arch frame 2, the auxiliary support member 34 further locks the arch frame 2, effectively preventing the arch frame 2 from falling off, and further improving the stability of the overall connection.
[0042] As a further embodiment of the present invention, it also includes a U-shaped air channel 344 opened on the auxiliary support member 34 , whose two air ports are both connected to the second slide groove 343 , and the U-shaped air channel 344 is connected to the cylinder 36 through the second air channel 321 .
[0043] Specifically, the second slider 341 is slidably arranged in the second slide groove 343. During the deformation process of the elastic plate 35, the connecting rod 351 arranged at the top of the arc of the elastic plate 35 is driven to push the piston plate 361 to move in the cylinder 36, thereby squeezing the air in the cylinder 36 into the second air channel 321, and then into the U-shaped air channel 344 through the second air channel 321, and finally into the second slide groove 343. As the air pressure in the second slide groove 343 increases, the second slider 341 is pushed to move and the second spring is stretched. The two second sliders 341 abut against each other, thereby limiting the arch frame 2 in the U-shaped groove of the auxiliary support member 34. When disassembling, it is only necessary to open the air outlet nozzle 363 and release the pressure and air through the air outlet pipe 362, so that the second slider 341 is pulled back by the second spring, and the lock of the second slider 341 can be directly released without the need for another driving source, further simplifying the structure and saving the manufacturing cost.
[0044] Working principle: the beam connecting frame 31 on the coupling body 3 is plugged and matched with the positioning block 11 set on the beam 1 to realize the pre-fixation of the coupling body 3, and then the arch frame 2 is directly installed. It is only necessary to make the arch top of the arch frame 2 push the elastic plate 35. The elastic plate 35 is deformed by the arch frame 2 and is clamped on the surface of the arch frame 2 in a C-shaped structure. During the deformation process of the elastic plate 35, the connecting rod 351 set at the top of the arc of the elastic plate 35 is driven to push the piston plate 361 to move in the cylinder 36, so that the air in the cylinder 36 is squeezed into the first air channel 312, and then enters the first slide groove 313 through the first air channel 312. The air pressure in a slide groove 313 increases, thereby pushing the first slider 311 to move and stretching the first spring, so that the first slider 311 cooperates with the pin of the positioning block 11, thereby fixing the coupling body 3 on the beam 1. At the same time, the air in the cylinder 36 is squeezed into the second air channel 321, and then enters the U-shaped air channel 344 through the second air channel 321, and finally enters the second slide groove 343. As the air pressure in the second slide groove 343 increases, the second slider 341 is pushed to move, and the two second sliders 341 abut against each other, thereby limiting the arch frame 2 in the U-shaped groove of the auxiliary support member 34, thereby achieving quick installation.
[0045] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
