Description

Technical Field

[0001] The present invention relates to the technical field of windows, and particularly relates to a push-pull top-hung window. Background Art

[0002] In the dairy farming industry, top-hung windows are mainly used in single units such as milking parlors and calving pens, installed at the top of the single unit. They can keep out the cold when closed in winter, resist rain, snow, wind and sand during rainy and windy seasons, and can be opened when the weather is good, which plays an important role in ensuring the indoor temperature, adjusting the indoor air circulation, and improving the indoor comfort.

[0003] With the continuous development of the industry, the installation position of top-hung windows is no longer limited to milking parlors or calving pens. From practical experience, it is found that in relatively cold regions, closing the ventilation openings at the ridge of the cowshed in winter can increase the milk production of dairy cows, and in summer, the ventilation openings at the ridge need to be kept open all the time. Therefore, in relatively cold regions, top-hung windows also need to be installed at the ridge of the cowshed.

[0004] A top-hung window for the ridge of a cowshed is disclosed in the Chinese utility model patent with the publication number CN208763313U, which includes a top window beam installed at the ridge, top-hung window forms on both sides and a top-hung window driving device. The top window beam is fixedly connected to the top of the roof truss. The upper end of the top-hung window form is hinged to the top window beam, and the lower end is a free end that cooperates with the roof. The top-hung window driving device includes a motor fixing frame fixedly installed on the roof truss, a transmission shaft arranged along the extension direction of the roof driven by a motor, and a gear-rack mechanism that meshes with each other. The motor is fixedly installed on the motor fixing frame. There are multiple gear-rack mechanisms. Among them, multiple gears are fixedly sleeved on the transmission shaft, the upper end of the rack is hinged to the top-hung window, and the lower end is a free end.

[0005] The opening method of the above top-hung window is to use power components such as motors, gears, and racks, and the entire top-hung window form is lifted upward through hinges or rotating shafts. After opening, the entire top-hung window is in a V shape. Such a design has the following defects: Since the traditional top-hung window is in a V shape after opening, the form is almost at a right angle to the roof. In this way, in strong wind weather, the wind load on the form will be very large. Over time, the sunlight panel on the form will become loose or even be blown off, and the gear-rack will also have problems due to the constant shaking caused by the wind, resulting in a malfunction of the entire top-hung window. In addition, since the traditional top-hung window is in a V shape after opening, when it is opened at the ridge of the cowshed in summer and it rains, water will accumulate at the center position of the form. Over time, it will also damage the top-hung window. Therefore, it is necessary to improve the relevant technology design. Summary of the Invention

[0006] In order to solve the above problems, the present invention provides a push-pull top-hung window.

[0007] The above technical object of the present invention is achieved by the following technical solutions: A push-pull type top-opening window, including a top-opening window form arranged at the ridge of the cowshed. The top-opening window form includes a first form arranged on one side of the roof at the top of the cowshed and a second form arranged on the other side of the roof at the top of the cowshed. There is a ventilation opening at the ridge of the cowshed, and the ventilation openings are symmetrically distributed on the roofs on both sides of the ridge of the cowshed. The first form and the second form cooperate to cover the ventilation opening. A driving mechanism is arranged in the cowshed for driving the first form and the second form to slide along the roofs on both sides of the top of the cowshed respectively, so as to open the ventilation opening for ventilation.

[0008] By adopting the above technical solutions, the driving mechanism can be used to make the first form and the second form slide along the roofs on both sides of the top of the cowshed respectively, thereby opening the ventilation opening for ventilation, changing the V-shaped design method of the top-opening window form in the traditional technology, and avoiding the problems that the top-opening window form is damaged by crosswind and the window-opening driving components are damaged, which is beneficial to extending the service life of the equipment.

[0009] Further, the driving mechanism includes a control component and a power component. There are two groups of control components, which are respectively used to drive the first form and the second form to open. The control component includes a mounting sleeve fixed to the inner top of the cowshed, a hollow sleeve fixed to the inner wall of the mounting sleeve, a sliding plate slidably matched with the inner wall of the hollow sleeve, a control rod fixed to the side of the sliding plate close to the ventilation opening, and a first spring fixed between the side of the sliding plate away from the ventilation opening and the inner wall of the side of the hollow sleeve away from the ventilation opening. The telescopic direction of the control rod is parallel to the inclination direction of the cowshed roof. The control rod penetrates through the end of the hollow sleeve close to the ventilation opening and is slidably matched. The control component further includes a connecting plate fixed to the end of the control rod away from the sliding plate. The top of the connecting plate is fixed to the first form or the second form. The bottom surfaces of the first form and the second form are respectively attached to the tops of the roofs on both sides of the cowshed. The power component is used to drive the two groups of sliding plates to slide along the inner wall of the hollow sleeve.

[0010] By adopting the above technical solutions, when opening the top-opening window form, the staff only needs to drive the two groups of sliding plates to slide along the inner wall of the hollow sleeve through the power component, so that the sliding plate pulls the first form or the second form through the control rod, and the opening actions of the first form and the second form can be completed simultaneously. The design is ingenious.

[0011] Further, the power assembly includes a cross plate fixed between two mounting sleeves, a first vertical plate fixed to the top of the cross plate, a motor fixed to the first vertical plate, a driving gear fixedly sleeved on the output end of the motor, a first winding wheel fixed to the output end of the motor, a first traction rope wound and fixed on the first winding wheel, a second vertical plate fixed to the top of the cross plate, a rotating shaft rotatably mounted on the second vertical plate, a driven gear fixedly sleeved on the rotating shaft and meshing with the driving gear, a second winding wheel fixed to the end of the rotating shaft, and a second traction rope wound and fixed on the second winding wheel. The other end of the first traction rope passes through the side wall of the hollow sleeve on one side and is fixed to the sliding plate on that side. The other end of the second traction rope passes through the side wall of the hollow sleeve on the other side and is fixed to the sliding plate on that side. A reset assembly for driving the first window and the second window to reset is provided on the cowshed.

[0012] By adopting the above technical solution, when opening the top-opening window form, the staff only needs to start the motor. After the motor works, it drives the driving gear and the first winding wheel to rotate. The first traction rope gradually winds tightly on the first winding wheel, so as to pull and open the second window form through the sliding plate and the control rod on one side. At the same time, the driving gear drives the driven gear, the rotating shaft and the second winding wheel to rotate, and the second traction rope gradually winds tightly on the second winding wheel, thereby pulling and opening the first window form through the sliding plate and the control rod on the other side, completing the opening action of the top-opening window form, which is beneficial to ventilation in the cowshed.

[0013] Further, a fixed pulley for reversing is rotatably mounted in each of the two hollow sleeves on both sides. The first traction rope and the second traction rope respectively bypass the fixed pulleys on both sides, and through holes for the first traction rope or the second traction rope to pass through are provided on the two hollow sleeves on both sides.

[0014] By adopting the above technical solution, the setting of the fixed pulley reduces the friction force suffered by the first traction rope and the second traction rope when passing through the hollow sleeve, reduces the wear of the first traction rope and the second traction rope, and prolongs the service life of the equipment.

[0015] Further, guide rails are fixed to the top of the cowshed roof. There are two guide rails on each side of the cowshed and they are symmetrically distributed on both sides of the first window or the second window. Both sides of the first window and the second window are slidably connected to the guide rails through sliding components.

[0016] By adopting the above technical solution, the setting of the guide rails and the sliding components reduces the resistance suffered by the first window and the second window during the movement along the cowshed roof.

[0017] Further, the guide rail is C-shaped. The middle section of the guide rail is parallel to the roof of the cowshed, and both ends of the guide rail are fixed to the top of the cowshed roof. The sliding assembly includes an L-shaped plate fixed to the side wall of the first window or the second window and a roller movably installed on the L-shaped plate. The mutually remote sides of the two guide rails are respectively in contact with the inner sides of the L-shaped plates on both sides. The roller is in rolling cooperation with the bottom surface of the middle section of the guide rail and the top of the cowshed roof, and at least two rollers are provided on each L-shaped plate.

[0018] By adopting the above technical solution, during the movement of the first window or the second window along the roof of the cowshed, the rollers on the L-shaped plate are respectively in rolling cooperation with the guide rail and the top of the cowshed roof, reducing the resistance during the movement of the first window or the second window along the roof of the cowshed.

[0019] Further, the reset assembly includes a first fixing plate fixed to the L-shaped plate, a second fixing plate fixed to the guide rail and parallel to the first fixing plate, and a second spring fixed between the second fixing plate and the first fixing plate.

[0020] By adopting the above technical solution, the second spring has a good elastic effect. During the reset process of the first window and the second window, the second spring provides an auxiliary reset function.

[0021] Further, an arc-shaped convex strip is integrally formed on one side of the second window, an arc-shaped groove cooperating with the arc-shaped convex strip is provided on one side of the first window, and an arc-shaped rubber sheet is attached to and fixed on the inner wall of the arc-shaped groove.

[0022] By adopting the above technical solution, after the first window and the second window are closed, the arc-shaped convex strip presses against the arc-shaped rubber sheet, enhancing the sealing performance of the connection between the first window and the second window, reducing the probability of rainwater leakage, and being beneficial to improving the dryness inside the cowshed.

[0023] Further, the connecting plate is V-shaped, and a reinforcing rib is fixed at the corner of the connecting plate.

[0024] By adopting the above technical solution, the structural stability of the connecting plate is improved.

[0025] In summary, the present invention has the following beneficial effects:

[0026] 1. The present application changes the design method in the traditional technology where the top-opening window form is V-shaped after being opened, avoiding the problems that the top-opening window form is damaged by crosswind and the window-opening driving components are damaged, which is beneficial to extending the service life of the equipment. In addition, the first window and the second window are respectively opened along the inclined plane directions on both sides of the roof, and the opened top-opening window form is not V-shaped, avoiding the problem of water accumulation;

[0027] 2. In this application, when opening the top-opening window form, the staff only need to drive two sets of sliding plates to slide along the inner wall of the hollow sleeve through the power component, so that the sliding plates pull the first form or the second form through the control rod, and the opening actions of the first form and the second form can be completed simultaneously, with a clever design.

[0036] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application; obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without making creative efforts belong to the scope of protection of the present application.

[0037] As Figures 1-7 shown, an embodiment of the present application discloses a push-pull top-hung window, which includes a top-hung window form 2 provided at the ridge of the cowshed 1. The top-hung window form 2 includes a first form 21 provided on one side of the roof at the top of the cowshed 1 and a second form 22 provided on the other side of the roof at the top of the cowshed 1. A ventilation opening 11 is provided at the ridge of the cowshed 1, and the ventilation openings 11 are symmetrically distributed on the roofs on both sides of the ridge of the cowshed 1. The first form 21 and the second form 22 cooperate to cover the ventilation opening 11. A driving mechanism 3 is provided in the cowshed 1 for driving the first form 21 and the second form 22 to slide along the roofs on both sides of the top of the cowshed 1 respectively, so as to open the ventilation opening 11 for ventilation.

[0038] By using the driving mechanism 3, the first form 21 and the second form 22 can slide along the roofs on both sides of the top of the cowshed 1 respectively, so as to open the ventilation opening 11 for ventilation, changing the traditional design method in which the top-hung window form 2 is in a V shape after being opened, avoiding the problem that the top-hung window form 2 is damaged by crosswind and the window opening driving components, which is beneficial to extending the service life of the equipment.

[0039] The driving mechanism 3 includes a control component 31 and a power component 32. There are two groups of control components 31, which are respectively used to drive the first form 21 and the second form 22 to open. The control component 31 includes a mounting sleeve 311 fixed to the inner top of the cowshed 1, a hollow sleeve 312 fixed to the inner wall of the mounting sleeve 311, a sliding plate 313 slidably fitted to the inner wall of the hollow sleeve 312, a control rod 314 fixed to the side of the sliding plate 313 close to the ventilation opening 11, and a first spring 315 fixed between the side of the sliding plate 313 away from the ventilation opening 11 and the inner wall of the side of the hollow sleeve 312 away from the ventilation opening 11. The telescopic direction of the control rod 314 is parallel to the inclination direction of the roof of the cowshed 1. The control rod 314 passes through and is slidably fitted to the end of the hollow sleeve 312 close to the ventilation opening 11. The control component 31 further includes a connecting plate 316 fixed to the end of the control rod 314 away from the sliding plate 313. The top of the connecting plate 316 is fixed to the first form 21 or the second form 22. The bottom surfaces of the first form 21 and the second form 22 are respectively attached to the tops of the roofs on both sides of the cowshed 1. The power component 32 is used to drive the two sliding plates 313 to slide along the inner wall of the hollow sleeve 312. In this embodiment, the connecting plate 316 is in a V shape, and a reinforcing rib 4 is fixed at the corner of the connecting plate 316.

[0040] When opening the top-opening window form 2, the staff only need to drive two sets of sliding plates 313 to slide along the inner wall of the hollow sleeve 312 through the power component 32, so that the sliding plates 313 pull the first form 21 or the second form 22 through the control rods 314, and the opening actions of the first form 21 and the second form 22 can be completed simultaneously, with a clever design.

[0041] The power component 32 includes a cross plate 321 fixed between two sets of mounting sleeves 311, a first vertical plate 322 fixed to the top of the cross plate 321, a motor 323 fixed to the first vertical plate 322 (to prevent the motor 323 from getting damp and rusty, a protective cover that sleeves the outside of the motor 323 can be fixed on the first vertical plate 322, not shown in the figure), a driving gear 324 fixedly sleeved on the output end of the motor 323, a first winding wheel 325 fixed to the output end of the motor 323, a first traction rope 326 wound and fixed on the first winding wheel 325, a second vertical plate 327 fixed to the top of the cross plate 321, a rotating shaft 328 rotatably mounted on the second vertical plate 327, a driven gear 329 fixedly sleeved on the rotating shaft 328 and meshing with the driving gear 324, a second winding wheel 330 fixed to the end of the rotating shaft 328, and a second traction rope 331 wound and fixed on the second winding wheel 330. The other end of the first traction rope 326 passes through the side wall of the hollow sleeve 312 on one side and is fixed to the sliding plate 313 on that side. The other end of the second traction rope 331 passes through the side wall of the hollow sleeve 312 on the other side and is fixed to the sliding plate 313 on that side. A reset component 5 for driving the first form 21 and the second form 22 to reset is provided on the cowshed 1.

[0042] When opening the top-opening window form 2, the staff only need to start the motor 323. After the motor 323 works, it drives the driving gear 324 and the first winding wheel 325 to rotate. The first traction rope 326 gradually winds tightly on the first winding wheel 325, so as to pull and open the second form 22 through the sliding plate 313 and the control rod 314 on one side. At the same time, the driving gear 324 drives the driven gear 329, the rotating shaft 328 and the second winding wheel 330 to rotate, and the second traction rope 331 gradually winds tightly on the second winding wheel 330, so as to pull and open the first form 21 through the sliding plate 313 and the control rod 314 on the other side, completing the opening action of the top-opening window form 2, which is beneficial to ventilation in the cowshed 1. When it is necessary to close the top-opening window form 2, the staff only need to start the motor 323 and rotate it in the reverse direction. Similarly, the second traction rope 331 gradually unwinds on the second winding wheel 330, and the sliding plate 313 resets under the elastic force of the first spring 315, so that the first form 21 and the second form 22 are reset and the ventilation opening 11 is closed.

[0043] Fixed pulleys 6 for reversing are rotatably mounted in the hollow sleeves 312 on both sides (the first spring 315 and the fixed pulley 6 are arranged in a staggered manner, such as Figure 4) The first towing rope 326 and the second towing rope 331 respectively bypass the fixed pulleys 6 on both sides, and through holes 3121 for the first towing rope 326 or the second towing rope 331 to pass through are provided on the hollow sleeves 312 on both sides.

[0044] The setting of the fixed pulleys 6 reduces the friction force suffered by the first towing rope 326 and the second towing rope 331 when passing through the hollow sleeves 312, reduces the wear of the first towing rope 326 and the second towing rope 331, and prolongs the service life of the equipment.

[0045] To reduce the resistance suffered by the first window 21 and the second window 22 during the movement along the roof of the cowshed 1, guide rails 12 are fixed at the top of the roof of the cowshed 1. There are two guide rails 12 on each side of the cowshed 1 and they are symmetrically distributed on both sides of the first window 21 or the second window 22. Both sides of the first window 21 and the second window 22 are slidably connected to the guide rails 12 through sliding components 7. Specifically: the guide rails 12 are C-shaped, the middle section of the guide rails 12 is parallel to the roof of the cowshed 1, both ends of the guide rails 12 are fixed to the top of the roof of the cowshed 1. The sliding component 7 includes an L-shaped plate 71 fixed to the side wall of the first window 21 or the second window 22 and a roller 72 movably installed on the L-shaped plate 71. The mutually remote sides of the two guide rails 12 are respectively in contact with the inner sides of the L-shaped plates 71 on both sides. The roller 72 is in rolling fit with the bottom surface of the middle section of the guide rail 12 and the top of the roof of the cowshed 1, and at least two rollers 72 are provided on each L-shaped plate 71. During the movement of the first window 21 or the second window 22 along the roof of the cowshed 1, the rollers 72 on the L-shaped plate 71 are in rolling fit with the guide rails 12 and the top of the roof of the cowshed 1 respectively, reducing the resistance during the movement of the first window 21 or the second window 22 along the roof of the cowshed 1.

[0046] The reset component 5 includes a first fixing plate 51 fixed to the L-shaped plate 71, a second fixing plate 52 fixed to the guide rail 12 and parallel to the first fixing plate 51, and a second spring 53 fixed between the second fixing plate 52 and the first fixing plate 51. The second spring 53 has a good elastic effect, and during the reset process of the first window 21 and the second window 22, the second spring 53 provides an auxiliary reset function.

[0047] An arc-shaped convex strip 221 is integrally formed on one side of the second window 22, and an arc-shaped groove 211 cooperating with the arc-shaped convex strip 221 is provided on one side of the first window 21. An arc-shaped rubber sheet 2111 is bonded and fixed to the inner wall of the arc-shaped groove 211.

[0048] After the first window 21 and the second window 22 are closed, the arc-shaped convex strip 221 abuts against the arc-shaped rubber sheet 2111, enhancing the sealing performance of the connection between the first window 21 and the second window 22, reducing the probability of rainwater leakage, and being beneficial to improving the dryness inside the cowshed 1.

[0049] In this embodiment, the working principle of a push-pull type top-hung window is as follows: By using the driving mechanism 3, the first window body 21 and the second window body 22 can slide along the roof on both sides of the top of the cowshed 1 respectively, so as to open the ventilation opening 11 for ventilation. This changes the V-shaped design mode of the top-hung window body 2 in the traditional technology, avoiding the problems that the top-hung window body 2 is damaged by crosswind and the window opening driving components are damaged, which is beneficial to extending the service life of the equipment.

[0050] Specifically: When opening the top-hung window body 2, the staff only need to start the motor 323. After the motor 323 works, it drives the driving gear 324 and the first wire winding wheel 325 to rotate. The first traction rope 326 gradually winds tightly on the first wire winding wheel 325, so as to pull and open the second window body 22 through the sliding plate 313 and the control rod 314 on one side. At the same time, the driving gear 324 drives the driven gear 329, the rotating shaft 328 and the second wire winding wheel 330 to rotate, and the second traction rope 331 gradually winds tightly on the second wire winding wheel 330, so as to pull and open the first window body 21 through the sliding plate 313 and the control rod 314 on the other side, completing the opening action of the top-hung window body 2, which is beneficial to ventilation in the cowshed 1.

[0051] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
