Description

Technical Field

[0001] The utility model relates to a hand-cranked screw window opening device, belonging to the technical field of screw transmission. Background Art

[0002] High-hung windows usually refer to top-hung windows, which are windows with hinges installed on the upper side of the window and can be opened inward or outward. In addition, according to the opening direction, hung windows can be divided into inward-opening and outward-opening. Suitable for office areas, providing larger workspace and better lighting.

[0003] Since high-hung windows are often installed at higher places, an automatic opening and closing device is often additionally provided on the hung windows when opening and closing such windows, thereby avoiding manual climbing to open the windows. However, the automatic opening and closing device requires power supply, and when a power outage occurs, it is difficult to manually open and close the hung windows. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a hand-cranked screw window opening device, which solves the problem in the prior art that high-hung windows cannot be opened manually in a power-off situation.

[0005] The technical problem to be solved by the utility model is achieved by adopting the following technical solutions: a hand-cranked screw window opening device, comprising a mounting frame for fixing a hanging window,

[0006] The support rod is mounted on the mounting frame on the inner side of the suspended window.

[0007] A rotating shell is disposed on the support rod, and the rotating shell can rotate around the support rod.

[0008] A telescopic rod assembly, one end of which is arranged in the rotating shell, and the other end is hinged to the opening and closing side of the hanging window,

[0009] A transverse transmission rod, which is arranged parallel to the support rod, one end of which is arranged in the rotating shell, and the other end of which is provided with a transmission shell, wherein a vertical transmission rod is connected in the transmission shell,

[0010] By adopting the above technical solution, the telescopic rod assembly rotates and retracts with the rotating shell as the center of the circle, thereby realizing the opening and closing of the hanging window. By rotating the vertical transmission rod, the horizontal transmission rod is driven to rotate under the meshing transmission action of bevel gear two and bevel gear three, and then the telescopic rod assembly is driven to rotate under the meshing transmission action of bevel gear one and bevel gear four, so that the telescopic rod assembly extends outward or retracts inward. When the telescopic rod assembly extends outward, the rotating shell rotates accordingly, so that the telescopic rod assembly extends outward and rotates around the support rod at the same time, thereby opening the hanging window. When the telescopic rod assembly retracts, the rotating shell rotates synchronously, driving the telescopic rod assembly to rotate around the support rod, pulling the hanging window back, and realizing the closing of the hanging window.

[0011] The utility model is further arranged such that bevel gear one and bevel gear two are respectively arranged at two ends of the transverse transmission rod, bevel gear three is arranged at one end of the vertical transmission rod located inside the transmission housing, bevel gear three meshes with bevel gear two, bevel gear four is arranged at one end of the telescopic rod assembly located inside the rotating housing, and bevel gear four is hinged to bevel gear one.

[0012] By adopting the above technical solution, through the meshing of bevel gears, the system can realize power transmission in different directions and different planes, such as between the inside of the rotating housing and the inside of the transmission housing. This flexibility enables the entire transmission system to adapt to more complex motion requirements.

[0013] The utility model is further arranged such that a rotating handle is arranged at the bottom end of the vertical transmission rod.

[0014] By adopting the above technical solution, it is more convenient for the window-opening personnel to control the rotational force of the vertical transmission rod, thereby making the opening and closing of the casement window more convenient and fast.

[0015] The utility model is further arranged such that the telescopic rod assembly includes an outer sleeve, one end of the outer sleeve is connected to the rotating housing, and the other end is provided with an opening.

[0016] An inner cavity of the outer sleeve is provided with a telescopic rod, one end of the telescopic rod is provided with a threaded sleeve, the inner ring of the threaded sleeve is provided with threads, and the other end of the telescopic rod is provided with a hinge member hinged to the side of the casement window.

[0017] The telescopic rod is provided with an inner cavity, a lead screw is arranged in the inner cavity of the telescopic rod, one end of the lead screw is connected to bevel gear four inside the rotating housing, and rotation is realized through the meshing transmission of bevel gear four and bevel gear one.

[0018] By adopting the above technical solution, the telescoping and rotation of the telescopic rod assembly can be quickly controlled, thereby enabling the quick opening and closing of the casement window. During the opening and closing process, bevel gear one rotates driven by the rotation of the transverse transmission rod. During the rotation process, bevel gear four meshing with bevel gear one also rotates accordingly, thereby driving the lead screw to rotate. When the lead screw rotates, the threaded sleeve sleeved on the lead screw rotates inside the outer sleeve and moves towards the outside of the outer sleeve, so that the telescopic rod connected to the threaded sleeve extends outwards, thereby pushing the casement window outwards to realize the opening and closing of the casement window. At the same time, during the meshing transmission of bevel gear one and bevel gear four, the rotating housing is also driven to rotate around the support rod, so that the casement window can rotate and open and close at both the horizontal angle and the vertical angle.

[0019] The utility model is further arranged such that the vertical transmission rod is telescopic.

[0020] By adopting the above technical solution, through the extension and retraction of the vertical transmission rod, when in use, the length of the vertical transmission rod can be adjusted by pulling the vertical transmission rod, and vertical transmission rods of different lengths can be suitable for opening and closing suspended windows of different heights.

[0021] The utility model is further configured as follows: the rotating shell is mounted on the support rod through a fixing frame arranged in the middle area of the support rod, the fixing frame is connected with two mounting plates, and the rotating shell is rotatably arranged between the two mounting plates.

[0022] By adopting the above technical solution, the fixing frame is set in the middle area of the support rod, which provides a stable support point for the rotating shell and enhances the stability of the entire structure. This design helps to reduce the vibration and shaking caused by the rotational movement, thereby improving the safety and reliability of the equipment. The rotating shell is firmly mounted on the support rod through the fixing frame, which effectively prevents the risk of the rotating shell falling off when rotating at high speed or under the action of external force, and ensures the continuity and stability of the equipment operation. The rotating shell is rotatably set between the two mounting plates so that it can rotate freely around the support rod. This design increases the flexibility of the equipment, and the rotation angle and speed of the rotating shell can be adjusted as needed to adapt to different working scenarios and needs. This design between the rotating shell and the mounting plate also facilitates the maintenance and overhaul of the equipment. When the rotating shell needs to be cleaned, replaced or repaired, the rotating shell can be easily disassembled and installed, reducing maintenance costs and time.

[0023] The utility model is further configured as follows: both ends of the support rod are fixed by a fixing frame with adjustable height.

[0024] By adopting the above technical solution, the height-adjustable fixing frame can control the maximum opening and closing degree of the hanging window. By controlling the vertical distance between the fixing frame and the opening and closing sides of the hanging window, the maximum opening distance of the hanging window after the telescopic rod assembly is opened can be changed, thereby limiting the maximum window opening distance according to different situations.

[0025] The beneficial effect of the utility model is that through the mutual meshing of multiple bevel gears and the arrangement of the telescopic rod assembly, the screw in the telescopic rod assembly can be controlled to rotate by rotating the vertical transmission rod, and the screw rotation causes the threaded sleeve sleeved on the screw to move along the screw, driving the telescopic rod connected to the threaded sleeve to extend outward or retract inward. Due to the meshing of bevel gear 1 and bevel gear 2, when the screw rotates, the entire rotating shell will also rotate accordingly, so that the entire telescopic rod assembly rotates around the support rod, and the hanging window is opened or closed in coordination with the telescopic rod extension.

Specific embodiments

[0032] In order to clearly understand the technical means, creative features, achieved purposes and effects of the present utility model, the present utility model will be further described below with reference to specific drawings.

[0033] As Figure 1 shown, a hand-cranked screw window opening device includes a mounting frame 1 for fixing a casement window 2. In this embodiment, the mounting frame 1 is integrally spliced with an aluminum alloy material frame, and the mounting frame 1 is fixed to the wall by bolts.

[0034] A support rod 3 is erected on the mounting frame 1 on the inner side of the casement window 2. An installation frame is erected on the support rod 3. The installation frame is first fixed at the middle section position of the support rod 3 before the support rod 3 is fixed to the mounting frame 1.

[0035] In this embodiment, the support rod 3 is installed through a fixing bracket 16. The fixing brackets 16 are arranged at both ends of the support rod 3, and the fixing brackets 16 and the installation frame are slidably installed. During the installation process, the position of the fixing brackets 16 on the installation frame can be adjusted, so that the support angle for supporting the opening and closing of the casement window 2 by the telescopic rod assembly 5 can be adjusted to a most reasonable state.

[0036] The rotating shell 4 is arranged on the support rod 3 and can rotate around the support rod 3. The inner cavity of the rotating shell 4 is a cavity for accommodating the first bevel gear 9 and the fourth bevel gear 12. The first bevel gear 9 and the fourth bevel gear 12 are meshed with each other in the inner cavity of the rotating shell 4. The first bevel gear 9 drives the fourth bevel gear 12 to rotate, so that the lead screw 504 connected to the bevel gear rotates, driving the threaded sleeve 503 sleeved on the lead screw 504 to rotate. The threaded sleeve 503 drives the telescopic rod 502 to expand and contract. During the expansion and contraction process of the telescopic rod 502, the rotating shell 4 can also rotate accordingly, so that the casement window 2 can be opened or closed under the support of the telescopic rod assembly 5.

[0037] As Figure 2 shown, wherein, shaft holes for installing the bearing seats of the transverse transmission rod 6 are arranged on both side surfaces of the rotating shell 4, and the transverse transmission rod 6 is installed through the bearing seats on the rotating shell 4.

[0038] The telescopic rod assembly 5 includes a lead screw 504. One end of the lead screw 504 is arranged in the rotating shell 4 and is connected with the fourth bevel gear 12 in the inner cavity of the rotating shell 4. The other end is hinged to the opening and closing side edge of the casement window 2 through a hinge 505, so that when the casement window 2 opens and closes, the telescopic rod assembly 5 can rotate relative to the casement window 2 at any time without interference.

[0039] As Figure 1 shown, the transverse transmission rod 6 is arranged parallel to the support rod 3. One end is arranged in the rotating shell 4, and the other end is provided with a transmission shell 13. A vertical transmission rod 7 is connected in the transmission shell 13. The main function of the transverse transmission rod 6 is to transmit the torsional force of the vertical transmission rod 7 to the lead screw 504.

[0040] As Figure 3 、 Figure 4 and 5 shown, wherein, the first bevel gear 9 and the second bevel gear 10 are respectively arranged at both ends of the transverse transmission rod 6, the third bevel gear 11 is arranged at one end of the vertical transmission rod 7 located in the transmission shell 13, the third bevel gear 11 is meshed with the second bevel gear 10, and the fourth bevel gear 12 is arranged at one end of the telescopic rod assembly 5 arranged in the rotating shell 4. The fourth bevel gear 12 is hinged to the first bevel gear 9.

[0041] By rotating the vertical transmission rod 7, under the meshing transmission of the second bevel gear 10 and the third bevel gear 11, the transverse transmission rod 6 is driven to rotate, and then under the meshing transmission of the first bevel gear 9 and the fourth bevel gear 12, the telescopic rod assembly 5 is driven to rotate, so that the telescopic rod assembly 5 extends outwards or contracts inwards.

[0042] When the telescopic rod assembly 5 extends outwards, the rotating shell 4 rotates accordingly, so that the telescopic rod assembly 5 rotates around the support rod 3 while extending outwards, thus opening the casement window 2.

[0043] When the telescopic rod assembly 5 contracts, the rotating shell 4 rotates synchronously, driving the telescopic rod assembly 5 to rotate around the support rod 3, pulling back the casement window 2, and realizing the closing of the casement window 2.

[0044] The telescopic rod assembly 5 includes an outer sleeve 501. One end of the outer sleeve 501 is connected to the rotating shell 4, and the other end is provided with an opening. The telescopic rod 502 extends out from the opening, and the end is connected to the hinge member 505.

[0045] The inner cavity of the outer sleeve 501 is provided with a telescopic rod 502. One end of the telescopic rod 502 is provided with a threaded sleeve 503. The inner ring of the threaded sleeve 503 is provided with threads, and the other end of the telescopic rod 502 is provided with a hinge member 505 hinged to the side of the casement window 2.

[0046] In this embodiment, the hinge member 505 is specifically a rectangular block rotatably connected to the end of the telescopic rod 502. Round holes are provided at both ends of the rectangular block and sleeved on the cylinder on the casement window 2 through the round holes, so that when the telescopic rod 502 opens the casement window 2, it can rotate relative to the casement window 2.

[0047] The telescopic rod 502 is provided with an inner cavity. A lead screw 504 is arranged in the inner cavity of the telescopic rod 502. One end of the lead screw 504 is connected to the bevel gear four 12 in the rotating shell 4, and the rotation is realized through the meshing transmission of the bevel gear four 12 and the bevel gear one 9.

[0048] Through the pairwise meshing transmission of the four bevel gears, the telescopic and rotation of the telescopic rod assembly 5 can be quickly controlled, so that the rapid opening and closing of the casement window 2 can be realized.

[0049] During the opening and closing process, the bevel gear one 9 rotates under the drive of the rotation of the transverse transmission rod 6.

[0050] During the rotation process, the bevel gear four 12 meshing with the bevel gear one 9 also rotates accordingly, driving the lead screw 504 to rotate. When the lead screw 504 rotates, the threaded sleeve 503 sleeved on the lead screw 504 rotates in the outer sleeve 501 and moves towards the outside of the outer sleeve 501, so that the telescopic rod 502 connected to the threaded sleeve 503 extends outwards, pushing the casement window 2 outwards and realizing the opening and closing of the casement window 2.

[0051] At the same time, during the meshing transmission process of the bevel gear one 9 and the bevel gear four 12, the rotating shell 4 is also driven to rotate around the support rod 3, so that the casement window 2 can be rotated and opened and closed at both the horizontal angle and the vertical angle.

[0052] The vertical transmission rod 7 is telescopic. By telescoping the vertical transmission rod 7, during use, the length of the vertical transmission rod 7 is adjusted by pulling the vertical transmission rod 7. The vertical transmission rods 7 of different lengths can be suitable for the opening and closing of casement windows 2 of different heights.

[0053] The rotating shell 4 is mounted on the support rod 3 through a fixing frame 14 provided in the middle area of the support rod 3. The fixing frame 14 is connected with two mounting plates 15, and the rotating shell 4 is rotatably arranged between the two mounting plates 15.

[0054] Both ends of the support rod 3 are fixed by fixing frames 16 with adjustable height.

[0055] The fixing frame 16 with adjustable height can control the maximum opening and closing degree of the casement window 2. By adjusting the vertical distance between the fixing frame 16 and the opening and closing side of the casement window 2, the maximum opening distance of the telescopic rod assembly 5 after being expanded can be changed, so that the maximum window opening distance can be limited according to different situations.

[0056] Working principle: When the casement window 2 opens and closes, the vertical transmission rod 7 is rotated by rotating the handle 8. After the vertical transmission rod 7 is engaged with the bevel gear III 11 through the bevel gear II 10, the horizontal transmission rod 6 connected to the bevel gear III 11 is driven to rotate. Then, the horizontal transmission rod 6 drives the lead screw 504 to rotate through the bevel gear I 9 and the bevel gear IV 12, so that the threaded sleeve 503 sleeved on the lead screw 504 moves on the lead screw 504 and extends or contracts the telescopic rod 502 outward or inward, pushing the casement window 2 outward or closing the casement window 2.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of protection required by the present invention. The scope of protection required by the present invention is defined by the appended claims and their equivalents.
