[0047] 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.

[0048] The core of the utility model is to provide a manual screw-type window opener, which does not require electricity and can open and close the window sash manually.

[0049] Please refer to Figure 1 A manual screw window opener includes a fixing assembly 1, a first deflector 2, a hand crank 3, a transmission rod 4, a connecting piece 5, a screw assembly 6, a second deflector 7 and a window sash connecting piece 8.

[0050] Specifically, the fixed component 1 is arranged on the window frame and extends along the arrangement direction of the window frame. The first steering gear 2 is arranged at one end or the middle of the arrangement direction of the window frame. The first steering gear 2 is used to transmit the input power. The input end of the first steering gear 2 is provided with a hand crank 3. The output end of the first steering gear 2 is provided with a transmission rod 4 arranged parallel to the fixed component 1. The transmission rod 4 connects the first steering gear 2 and the second steering gear 7. Power is input to the first steering gear 2 through the rotation of the hand crank 3. The input power passes through the first steering gear 2 and is output from the output end of the first steering gear 2 to the transmission rod 4 to drive the transmission rod 4 to rotate. Then, the power is transmitted to the second steering gear 7 through the transmission rod 4.

[0051] The screw assembly 6 is telescopically arranged between the second deflector 7 and the window sash connecting member 8. By arranging the screw assembly 6 between the second deflector 7 and the window sash connecting member 8, the window sash can be opened and closed. One end of the screw assembly 6 is rotatably connected to the window sash connecting member 8 to ensure that the screw assembly 6 will not interfere with the window sash during the extension and retraction process. The input end of the second deflector 7 is connected to the transmission rod 4, and the input power is transmitted to the second deflector 7 through the transmission rod 4. The output end of the second deflector 7 is connected to the other end of the screw assembly 6. The input power passes through the second deflector 7 and is output from the output end of the second deflector 7 to the screw assembly 6, so as to drive the screw assembly 6 to telescopically move, thereby realizing the opening and closing of the window sash.

[0052] It is understandable that providing a window sash connector 8 at the connection between the screw assembly 6 and the window sash can prevent the screw assembly 6 from interfering with the window sash during extension and retraction. In practical applications, other connection methods can also be used as long as the above-mentioned technical effects can be achieved.

[0053] Among them, the fixing component 1 can be arranged in the middle of the window frame or near the middle and lower part of the window frame, without limitation. In this way, the problem that it is inconvenient to install the window opener because the window frame is too high can be effectively solved. Correspondingly, one end of the screw assembly 6 is arranged on the transmission rod 4, and the other end of the screw assembly 6 is arranged at a position near the bottom of the window sash. This arrangement facilitates opening and closing of the window sash.

[0054] When using the manual screw window opener arranged in the above manner, the hand crank 3 is rotated forward to control the screw assembly 6 to extend so as to open the window sash, and the hand crank 3 is rotated reversely to control the screw assembly 6 to retract so as to close the window sash; the hand crank 3 can also be rotated forward to control the screw assembly 6 to retract so as to close the window sash, and the hand crank 3 is rotated reversely to control the screw assembly 6 to extend so as to open the window sash.

[0055] In the above embodiment, the screw assembly 6 includes a hand-cranked push shaft 61 and a push rod 62. The hand-cranked push shaft 61 is a hollow structure, and a lead screw is provided inside the hand-cranked push shaft 61. The lead screw has an external thread structure. The push rod 62 is provided inside the hand-cranked push shaft 61, and the push rod 62 is provided with an internal thread structure. The external thread structure and the internal thread structure are matched with each other.

[0056] It should be noted that one end where the hand-cranked push shaft 61 and the push rod 62 are connected is provided with corresponding internal thread structure and external thread structure. Through the cooperation of the internal thread structure and the external thread structure, the extension and contraction of the push rod 62 are realized, thereby realizing the opening and closing of the window sash.

[0057] When the hand-cranked push shaft 61 rotates forward, the push rod 62 engaged by the thread extends out, thereby supporting the window sash to open outward. When the hand-cranked push shaft 61 rotates reversely, the push rod 62 engaged by the thread contracts, thereby driving the window sash to close inward.

[0058] Alternatively, when the hand-cranked push shaft 61 rotates forward, the push rod 62 engaged by the thread contracts, thereby driving the window sash to close inward, and when the hand-cranked push shaft 61 rotates reversely, the push rod 62 engaged by the thread extends, thereby driving the window sash to open outward.

[0059] There is no restriction on the direction of the thread as long as the above-mentioned technical effect can be achieved.

[0060] Please refer to Figure 2 The first steering gear 2 includes a first base 21, a first transverse hexagonal bevel gear 22, a longitudinal cylindrical bevel gear 23 and a first upper cover. The first transverse hexagonal bevel gear 22 is rotatably arranged on the first base 21, and the longitudinal cylindrical bevel gear 23 is rotatably arranged on the first base 21. The longitudinal cylindrical bevel gear 23 is coaxially arranged with the hand crank 3. The longitudinal cylindrical bevel gear 23 and the first transverse hexagonal bevel gear 22 are cross-overlappingly engaged with each other. The longitudinal cylindrical bevel gear 23 drives the first transverse hexagonal bevel gear 22 to rotate. The first transverse hexagonal bevel gear 22 is coaxially arranged with the transmission rod 4, and the first upper cover is buckled with the first base 21.

[0061] It should be noted that, by operating the hand crank 3, the longitudinal cylindrical bevel gear 23 installed on the first base 21 is driven to rotate, so as to drive the first transverse hexagonal bevel gear 22 on the longitudinal cylindrical bevel gear 23 to rotate, and the power is transmitted to the transmission rod 4 through the first transverse hexagonal bevel gear 22 to drive the transmission rod 4 to rotate synchronously. A first upper cover is provided on the first base 21 to improve the aesthetics of the first steering gear 2, and it also has dustproof and waterproof effects.

[0062] Among them, the transmission rod 4 is sleeved on the rotating shaft of the first transverse hexagonal bevel gear 22 so that the transmission rod 4 and the first transverse hexagonal bevel gear 22 rotate synchronously. In actual applications, the transmission rod 4 can also be directly connected to the rotating shaft of the first transverse hexagonal bevel gear 22 to achieve the above-mentioned technical effect, and there is no limitation on this.

[0063] In the above embodiment, the first base 21 is arranged on the window frame through a spacer block.

[0064] It is understandable that the pad can be a structure with a shock-absorbing function to avoid mechanical vibration when the hand crank 3 rotates to transmit power, thereby causing wear to the window frame. The pad can also be made of a material with a certain softness to avoid wear on the window frame due to excessive hardness. Because the pad has a certain thickness, the hand crank 3 can be rotated smoothly without causing inconvenience in operation due to being too close to the window frame.

[0065] Among them, in actual applications, there is no restriction on the specific thickness, specifications, material, etc. of the pad, as long as the above-mentioned technical effects can be achieved.

[0066] On the basis of the above embodiment, the hand crank 3 is connected to the longitudinal cylindrical bevel gear 23 via a universal joint.

[0067] It should be noted that, through the setting of the universal joint, the power input by the hand crank 3 is transmitted to the longitudinal cylindrical bevel gear 23, so as to realize the opening and closing of the window sash. In practical applications, there is no restriction on the connection method between the hand crank 3 and the longitudinal cylindrical bevel gear 23, as long as the above-mentioned technical effect can be achieved.

[0068] Please refer to Figure 3 The second steering gear 7 includes a second base 71, a second transverse hexagonal bevel gear 72, a longitudinal bevel gear 73 and a second upper cover 74. The second transverse hexagonal bevel gear 72 is coaxially arranged with the transmission rod 4, and the second transverse hexagonal bevel gear 72 is rotatably arranged on the second base 71. The longitudinal bevel gear 73 and the second transverse hexagonal bevel gear 72 are cross-overlappingly engaged with each other. The longitudinal bevel gear 73 is rotatably arranged on the second base 71. The second transverse hexagonal bevel gear 72 drives the longitudinal bevel gear 73 to rotate, and the second upper cover 74 is buckled on the second base 71.

[0069] It can be understood that the power input from the hand crank 3 is transmitted to the second transverse hexagonal bevel gear 72 in the second base 71 through the transmission rod 4, so that the second transverse hexagonal bevel gear 72 and the transmission rod 4 rotate synchronously, and the rotation of the second transverse hexagonal bevel gear 72 drives the longitudinal bevel gear 73 to rotate, and the longitudinal bevel gear 73 drives the hand crank push shaft 61 and the push rod 62 to move, so as to realize the opening and closing of the window sash.

[0070] The second base 71 is provided with a second upper cover 74 to improve the aesthetics of the second diverter 7 and to provide dustproof and waterproof effects. In practical applications, there is no restriction on the connection method between the longitudinal short shaft 74 and the hand-cranked push shaft 61, as long as the above technical effects can be achieved.

[0071] As a preferred embodiment, the fixing assembly 1 includes a mounting bracket 11 and a square tube 12 . Two or more mounting brackets 11 are provided. The two or more mounting brackets 11 are arranged in parallel on both sides of the window frame. The square tube 12 is provided on the mounting bracket 11 .

[0072] It should be noted that the square tube 12 is fixed to the mounting bracket 11 by screws, and the square tube 12 can be provided to limit the rotation of the square tube 12 when the hand-cranked push rod 62 moves.

[0073] In the above situation, the square tube 12 is connected to the second diverter 7 through the connecting member 5. The connecting member 5 is provided with a square hole for installing the square tube 12 and a round hole for installing the second diverter 7. The second diverter 7 is rotatably arranged in the round hole, and the connecting member 5 is arranged on both sides of the second base 71.

[0074] In the above embodiment, a handle is provided at the end of the hand crank 3, and an anti-slip structure is provided on the outer periphery of the handle.

[0075] It should be noted that a handle is provided at the end of the hand crank 3 to facilitate hand cranking and avoid collision between the hand and the window frame during hand cranking. An anti-slip structure is provided on the handle to avoid slipping during hand cranking.

[0076] Among them, the anti-skid structure can be an anti-skid pattern, anti-skid glue, anti-skid gasket, etc., and there is no limitation to this, as long as the above-mentioned technical effect can be achieved.

[0077] In summary, the manual screw window opener provided by the utility model, when it is necessary to open the window sash, the handle is rotated forward to input power to the longitudinal cylindrical bevel gear 23, so that the longitudinal cylindrical bevel gear 23 and the hand crank 3 rotate synchronously, and the first transverse hexagonal bevel gear 22 is driven to rotate by the longitudinal cylindrical bevel gear 23, so that the first transverse hexagonal bevel gear 22 outputs power to the transmission rod 4, and then inputs power from the second transverse hexagonal bevel gear 72 to drive the longitudinal bevel gear 73 to rotate, so that the longitudinal bevel gear 73 outputs power to the hand crank push shaft 61, and through the cooperation of the hand crank push shaft 61 and the push rod 62, the push rod 62 is extended to open the window sash, and when the window sash needs to be closed, the handle is rotated in the opposite direction to realize the closing process of the window sash.

[0078] It should be noted that, in this specification, relational terms such as first and second are merely used to distinguish one entity from other entities, but do not necessarily require or imply any actual relationship or order between these entities.
