Description

Technical Field

[0001] The utility model relates to the technical field of vegetable greenhouses, in particular to an electric window opening device for a vegetable greenhouse. Background Art

[0002] The vegetable greenhouse is a frame-covered structure with excellent thermal insulation performance. Some existing vegetable greenhouses are equipped with side-flip windows. In order to prevent the weight of the window from being fully pressed on one axis, the side-flip windows are often set on the outside of the vegetable greenhouse. The main structures include column supports, motors, drive racks, etc., which can provide auxiliary support for the side-flip windows and reduce the pressure on the rotating shaft of the windows. However, due to maintenance needs and cost considerations, the height of the motor cannot be set very high, resulting in a low position at the rack rotation point. The height of the motor is often lower than the height of the rotating shaft of the side-flip window. The motor drives the rack to pull the side-flip window to deflect until the rack and the side-flip window are in a straight line. At this time, the side-flip window is at the maximum angle. Because the motor rotates in the opposite direction, it will cause the side-flip window to close, so the opening angle of the window is not large enough, and can only form an acute angle at most. For this reason, we propose an electric window opening device for vegetable greenhouses. Utility Model Content

[0003] A technical problem to be solved by the present application is: how to design a structure that can make the opening angle of the window large enough without changing the existing design and without affecting the normal use of the electric window opening.

[0011] In some embodiments, the rebound assembly includes a spring 1 arranged on the side wall, and the two ends of the spring 1 are respectively fixedly connected to the side wall and the mounting shaft. A fixed block is also slidably arranged on the side wall, and the fixed block slides on plate 1. A spring 2 is arranged on the fixed block, and the two ends of the spring 2 are respectively fixedly connected to the fixed block and the side wall.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Example 1

[0032] See also Figure 1-9 The utility model provides a technical solution: an electric window opening device for a vegetable greenhouse, comprising a side wall 1 of the greenhouse, and an external drive motor 2, a rotating shaft 3 is rotatably arranged on the side wall 1, and a flip window 4 is fixedly connected to the rotating shaft 3, and also includes:

[0033] There are two ratchet wheels 5, both of which are fixed on the rotating shaft 3, and the two tooth grooves are in opposite directions;

[0034] The mounting shaft 15 is slidably arranged on the side wall 1, and ratchet pawls cooperating with the ratchet wheels 5 are respectively arranged on the mounting shaft 15, and only one ratchet wheel 5 is always engaged with one ratchet pawl;

[0035] Two through slots 16 are formed on the side wall 1 , and the two ratchets 5 are respectively located in the through slots 16 . A groove 17 is formed on the back of the side wall 1 between the two through slots 16 . The mounting shaft 15 slides through the groove 17 , and its two ends are respectively located in the two grooves 17 .

[0036] The push-up component 7 is arranged on the side wall 1 and connected to the mounting shaft 15. When the flip window 4 is flipped to the top and the bottom, the installation shaft 15 is driven to move by the push-up component 7 to switch the engaged ratchet wheel 5 and the pawl. Specifically, the push-up component 7 includes a rod 1 72 rotatably connected to one end of the sliding and mounting shaft 15, a plate 1 73 rotatably arranged on the other end of the rod 1 72, a baffle 74 is hinged on the plate 1 73, and a plate 2 75 is fixedly arranged on the rotating shaft 3, and the plate 2 75 is in contact with the baffle 74;

[0037] When the flip window 4 is deflected to the maximum angle, the flip window 4 is in contact with the side wall 1. During this process, the rotating shaft 3 rotates, driving the second plate 75 to rotate, and the second plate 75 contacts the baffle 74, so that the second plate 75 pushes the baffle 74 to slide, thereby driving the first plate 73 to slide, and then driving the rod 1 72 to deflect and tilt, thereby driving the installation shaft 15 to slide, and then driving the pawl to slide. Because the distance between the two pawls is smaller than the distance between the two one-way ratchet wheels 5, that is, only one pawl can mesh with the one-way ratchet wheel 5, and the installation shaft 15 slides. , causing the ratchet pawl originally engaged with the one-way ratchet 5 to disengage therefrom, and the ratchet pawl on the other side begins to engage with the one-way ratchet 5. The one-way ratchet 5 used at this time is opposite to the one-way ratchet 5 used when the flip window 4 was deflected before, that is, the deflection direction of the flip window 4 is different, and the one-way ratchet 5 used is also different, so that when the flip window 4 is deflected, it can only deflect in one direction. In this way, when the motor 2 rotates in the opposite direction, the flip window 4 can only deflect in a fixed direction. The advantage is that it is convenient to switch, and the flip window 4 can be opened to the maximum.

[0038] The mounting shaft 15 is provided with a rebound component 8, and the mounting shaft 15 is driven to automatically return to its position by the rebound component 8. Specifically, the rebound component 8 includes a spring 81 arranged on the side wall 1, and the two ends of the spring 81 are respectively fixedly connected to the side wall 1 and the mounting shaft 15. A fixed block 82 is also slidably arranged on the side wall 1, and the fixed block 82 slides on the plate 1 73. A spring 2 83 is arranged on the fixed block 82, and the two ends of the spring 2 83 are respectively fixedly connected to the fixed block 82 and the side wall 1. A pull rope 84 is arranged on the fixed block 82 to automatically return the mounting shaft 15 to its original position by the spring 81. Originally, the fixed block 82 is in contact with the plate 1 73 and abuts against it. When the plate 1 73 slides, the fixed block 82 pops out under the elastic force of the spring 2 83 and is inserted into the plate 1 73. 3, thereby limiting the plate 1 73 so that it cannot move, and further limiting the mounting shaft 15, thereby limiting the pawl so that it remains stationary. When the flip window 4 is turned back to close the window on the side wall 1, the flip window 4 is rotated in the opposite direction. When the flip window 4 is closed, the pressing block 1 9 slides, and further pulling the pull rope 84, thereby driving the fixed block 82 to slide, and the fixed block 82 slides to disengage from the plate 1 73. Without the limitation of the fixed block 82, the plate 1 73 drives the mounting shaft 15 to slide under the elastic force of the spring 1 81, and further drives the pawl to slide, thereby disengaging the pawl, and the pawl on the other side engages with the one-way ratchet 5, and the pawl is reset to the state when the flip window 4 is opened at the beginning, waiting for the next window opening and closing operation.

[0039] A block 9 is slidably provided on the side wall 1, and the block 9 is fixedly connected with the pull rope 84. The block 9 contacts the flip window 4 to drive the fixed block 82 to slide through the block 9. The flip window 4 deflects back, presses the block 9, pulls the pull rope 84, drives the fixed block 82 to slide, and then unlocks the plate 73. The advantage is that it can be unlocked automatically.

[0040] A torsion spring 10 is provided on the pawl, and the two ends of the torsion spring 10 are fixedly connected to the mounting shaft 15 and the pawl respectively, so as to drive the pawl to automatically return to its position through the elastic force of the torsion spring 10. When the pawl rotates and deflects, the pawl is automatically reset by the torsion spring 10, and can be automatically reset when it is in a good state.

[0041] A second shaft 11 is arranged outside the greenhouse, and the second shaft 11 is fixedly connected to the output shaft of the motor 2. A toothed disc 12 is installed on the second shaft 11, and a rack 13 is rotatably arranged on the end of the flip window 4 away from the rotating shaft 3. The rack 13 and the toothed disc 12 are meshed with each other to drive the flip window 4 to deflect through the rack 13. The motor 2 is started by program control. This part is designed with software control and is a prior art. The electric start drives the second shaft 11 to rotate, thereby driving the toothed disc 12 to rotate, and then driving the rack 13 to slide, thereby driving one end of the flip window 4 to start deflecting, so that the flip window 4 can be opened, and the flip window 4 is supported by a column, which has the advantage of auxiliary support and reducing the pressure on the rotating shaft 3.

[0044] A protective cover 14 is provided on the side wall 1 , and a one-way ratchet 5 is placed inside the protective cover 14 . The advantage is that the one-way ratchet 5 can be protected and the sealing property of the side wall 1 can be increased. When the flap 4 is closed, the sealing property of the side wall 1 is increased by the protective cover 14 .
