[0048] refer to Figure 4-Figure 6 , an embodiment of the present invention provides a sliding mechanism, comprising:

[0049] A first pulley bracket 110, the first pulley bracket 110 is slidably disposed on the frame;

[0050] A first pulley 120 and a first hook 130, wherein the first pulley 120 and the first hook 130 are rotatably disposed on the first pulley bracket 110;

[0051] A first swing arm 140, a first end of the first swing arm 140 can rotate around the first pulley bracket 110; and

[0052] A first fixing seat 150, the first fixing seat 150 is rotatably disposed at the second end of the first swing arm 140 and is used to connect with the movable fan;

[0053] Among the rotation axis of the first pulley 120 , the rotation axis of the first hook 130 , and the rotation axis of the first swing arm 140 , at least two are coaxially arranged.

[0054] The first pulley 120 and the first hook 130 are rotatably disposed on the first pulley bracket 110 , respectively. For example, the first pulley 120 and the first hook 130 are disposed at the same position and are stacked, or the first pulley 120 and the first hook 130 are disposed at different positions.

[0055] The first hook 130 can rotate around the first pulley bracket 110. When installing, only the first hook 130 needs to be rotated to fix one side of the sliding mechanism. Figure 1 and Figure 2 After the upper slide rail 7 of the frame 1 is installed, the first hook 130 is rotated to fix the first hook 130, the first pulley 120 and the first pulley bracket 110, that is, one side of the sliding mechanism is fixed.

[0056] One end of the first swing arm 140 is the first end, and the other end of the first swing arm 140 away from the first end is the second end. After one side of the sliding mechanism is fixed, the first swing arm 140 can rotate around the first pulley bracket 110. Since the first pulley 120 is arranged on the first pulley bracket 110, the friction force is reduced through the action of the first pulley 120, which helps the first swing arm 140 to rotate.

[0057] The first fixing seat 150 is disposed at the second end of the first swing arm 140. During installation, only the first fixing seat 150 needs to be fixed to fix the other side of the sliding mechanism. Figure 1 and Figure 2 After the upper sash frame 8 of the movable sash 2 is attached, the first fixing seat 150 is fixed by screwing in screws, that is, the other side of the sliding mechanism is fixed. After the other side of the sliding mechanism is fixed, the first swing arm 140 can rotate around the first fixing seat 150. In combination with the above, the door or window can be opened by rotating the first swing arm 140 at the first end and the second end.

[0058] The sliding mechanism provided by the present invention comprises a first pulley bracket 110, a first pulley 120, a first hook 130, a first swing arm 140 and a first fixed seat 150, wherein the first pulley bracket 110 is slidably arranged on the frame, the first pulley 120 and the first hook 130 are rotatably arranged on the first pulley bracket 110 respectively, the first end of the first swing arm 140 can rotate around the first pulley bracket 110, the first fixed seat 150 is rotatably arranged at the second end of the first swing arm 140 and is used to connect with the movable fan, wherein at least two of the rotation axes of the first pulley 120, the first hook 130 and the first swing arm 140 are coaxially arranged. The sliding mechanism is easy to install, has a simplified structure, has strong stability and can effectively reduce costs.

[0059] refer to Figure 4-Figure 8 , Fig.10 In some specific embodiments of the present invention, a first implementation of the sliding mechanism is provided, in which the rotation axis of the first pulley 120, the rotation axis of the first hook 130 and the rotation axis of the first swing arm 140 are coaxially arranged.

[0060] Specifically, the first pulley bracket 110 is provided with a first groove, the first groove is provided with a first sub-groove 111, the first pulley 120 is provided on the first sub-groove 111, the first hook 130 is provided on the first pulley 120, and the first hook 130 can rotate around the first pulley 120; the center of the first sub-groove 111 is provided with a first rotation groove 1111, the center of the first pulley 120 is provided with a second rotation groove 121, the first swing arm 140 is provided with a third rotation groove 1411 at a corresponding position of the first sub-groove 111, and the sliding mechanism further includes a first rotation shaft 160, and the first rotation shaft 160 is sequentially provided through the third rotation groove 1411, the first rotation groove 1111 and the second rotation groove 121. The first end of the first swing arm 140 can rotate around the rotation center by setting the rotation center with the first rotation shaft 160. The sliding mechanism of the first implementation method integrates the first pulley 120 and the first hook 130 together, and only needs one first pulley 120 and one first hook 130 to achieve fixation, which is convenient to install, has a simplified structure, strong stability and can effectively reduce costs.

[0061] refer to Figure 7 The first pulley bracket 110 is provided with a first sub-groove 111, and the first sub-groove 111 can be used to accommodate the first pulley 120. The shape of the first sub-groove 111 can be adapted to the shape of the first pulley 120, so that the first pulley 120 is partially or completely accommodated in the first sub-groove 111. Figure 4 , Figure 7 and Figure 8, the first pulley 120 is in the shape of a cylinder, the first sub-groove 111 is in the shape of a circle with two sides cut flat, and the first pulley 120 is accommodated in the first sub-groove 111 and partially protrudes from the first sub-groove 111. In some embodiments, the first sub-groove 111 can also be designed to be in the shape of a circle, so that the first pulley 120 in the shape of a cylinder is completely accommodated therein.

[0062] refer to Figure 7 The first sub-groove 111 is provided with a sufficient depth to accommodate the first pulley 120 and the first hook 130 disposed on the first pulley 120. The shape of the first sub-groove 111 can be adapted to the shape of the first hook 130, so that the first hook 130 is partially or completely accommodated in the first sub-groove 111. Figure 4 , Figure 7 and Fig. 9 , the first hook 130 is a circular shape with two sides cut flat, the first sub-groove 111 is a circular shape with two sides cut flat, the first pulley 120 is accommodated in the first sub-groove 111, the first hook 130 is arranged on the first pulley 120, the first hook 130 is also accommodated in the first sub-groove 111, and the first hook 130 is completely accommodated in the first sub-groove 111. In some embodiments, the first hook 130 can also be designed as other shapes to partially protrude from the first sub-groove 111. In some ways, the first sub-groove 111 can also be set to a depth that is only enough to accommodate the first pulley 120, the first hook 130 is arranged on the first pulley 120, and the first hook 130 partially or completely protrudes from the first sub-groove 111.

[0063] The first hook 130 is disposed on the first pulley 120, and the first hook 130 can rotate around the first pulley 120. When installing, only the first hook 130 needs to be rotated to fix one side of the sliding mechanism. Figure 1 and Figure 2 After the upper slide rail 7 of the frame 1 is installed, the first hook 130 is rotated to fix the first hook 130, the first pulley 120 and the first pulley bracket 110, that is, one side of the sliding mechanism is fixed. In addition, the first hook 130 and the first pulley 120 are integrated to reduce friction and help the first hook 130 to rotate.

[0064] refer to Figure 4-Figure 6 , Fig. 9In some specific embodiments of the present invention, a fourth rotation slot 131 is provided at the center of the first hook 130, and the first rotation axis 160 passes through the third rotation slot 1411, the first rotation slot 1111, the second rotation slot 121 and the fourth rotation slot 131 in sequence. The first rotation axis 160 can rotate. When the first rotation axis 160 rotates, since the first pulley bracket 110 is stuck in the upper slide rail 7 of the frame 1, the first pulley bracket 110 will not rotate with it, and the first hook 130 will rotate with the first rotation axis 160, thereby achieving the fixation of the first hook 130. During the rotation of the first hook 130, the first pulley 120 can reduce friction and help the rotation of the first hook 130. Through the first rotation axis 160, the rotation centers of the first end of the first swing arm 140, the first pulley 120 and the first hook 130 are on the same straight line, which is conducive to integrated design and can avoid the occurrence of rotation deviation.

[0065] refer to Fig.12 In some specific embodiments of the present invention, the first rotating shaft 160 includes a first base 161, a first rotating sub-shaft 162 provided on the first base 161 and corresponding to the position of the first end of the first swing arm 140, a second rotating sub-shaft 163 provided on the first rotating sub-shaft 162 and corresponding to the bottom of the first sub-groove 111 and the position of the first pulley 120, and a third rotating sub-shaft 164 provided on the second rotating sub-shaft 163 and corresponding to the position of the first hook 130. The first rotating sub-shaft 162 is circular in cross-section perpendicular to its rotation center, the second rotating sub-shaft 163 is circular in cross-section perpendicular to its rotation center, and the third rotating sub-shaft 164 is polygonal in cross-section perpendicular to its rotation center. The radius of the circular cross-section of the first rotating sub-shaft 162 is greater than the radius of the circular cross-section of the second rotating sub-shaft 163.

[0066] The first base 161 supports the first rotating sub-axis 162, the second rotating sub-axis 163, and the third rotating sub-axis 164. By screwing the first base 161, the first rotating shaft 160 can be screwed into the third rotating groove 1411, the first rotating groove 1111, the second rotating groove 121, and the fourth rotating groove 131. When the first end of the first swing arm 140 rotates around the first pulley bracket 110, the third rotating groove 1411 can rotate on the first rotating sub-axis 162; when the first rotating shaft 160 rotates, the friction between the third rotating sub-axis 164 and the fourth rotating groove 131 drives the first hook 130 to rotate.

[0067] Since the first end of the first swing arm 140 often rotates after being fixed, the radius of the circular cross section of the first rotating sub-axis 162 is designed to be slightly larger, which is helpful for the rotation of the first end of the first swing arm 140. The function of the first pulley 120 is to reduce friction, so the radius of the circular cross section of the second rotating sub-axis 163 is designed to be slightly smaller, and the first pulley 120 can still provide a corresponding function of reducing friction. In addition, the third rotating sub-axis 164 is designed to be a polygon in the cross section perpendicular to its rotation center, in order to help drive the rotation of the first hook 130, thereby helping to fix the first hook 130.

[0068] refer to Figure 4-Figure 6 , Fig.10 and Fig.11 In some specific embodiments of the present invention, the first swing arm 140 is provided with a twenty-seventh rotation groove 1421 at the position of the second end, and the first fixed seat 150 is provided with a twenty-eighth rotation groove 151 at the corresponding position of the second end, and the sliding mechanism further includes an eleventh rotation shaft 170, and the eleventh rotation shaft 170 is connected to the twenty-seventh rotation groove 1421 and the twenty-eighth rotation groove 151 respectively. The second end of the first swing arm 140 can rotate around the first fixed seat 150, and the first fixed seat 150 is inserted into the upper fan frame 8 of the movable fan 2, and the first fixed seat 150 will not rotate. Through the eleventh rotation shaft 170, the rotation center of the second end of the first swing arm 140 is located on the first fixed seat 150, which is conducive to integrated design and can avoid rotation deviation.

[0069] refer to Fig.13 In some specific embodiments of the present invention, the eleventh rotating shaft 170 includes a first rotating body 171 and a fourth rotating sub-shaft 172 and a fifth rotating sub-shaft 173 arranged on both sides of the first rotating body 171, the fourth rotating sub-shaft 172 corresponds to the position of the second end of the first swing arm 140, the fifth rotating sub-shaft 173 corresponds to the position of the first fixed seat 150, the first rotating body 171 is circular in a cross-section perpendicular to its rotation center, the fourth rotating sub-shaft 172 is circular in a cross-section perpendicular to its rotation center, the fifth rotating sub-shaft 173 is circular in a cross-section perpendicular to its rotation center, and the radius of the circular cross-section of the first rotating body 171 is greater than the radius of the circular cross-section of the fourth rotating sub-shaft 172 and the radius of the circular cross-section of the fifth rotating sub-shaft 173.

[0070] The first rotating body 171 supports the fourth rotating sub-axis 172 and the fifth rotating sub-axis 173. When the second end of the first swing arm 140 rotates around the first fixing seat 150, the twenty-seventh rotating groove 1421 can rotate on the fourth rotating sub-axis 172. Since the first rotating body 171 plays a supporting role, the radius of the circular cross section of the first rotating body 171 is designed to be slightly larger to enhance the supporting role of the first rotating body 171. In addition, the radius of the circular cross section of the first rotating body 171 is larger than the radius of the circular cross section of the fourth rotating sub-axis 172 and the radius of the circular cross section of the fifth rotating sub-axis 173, which is also conducive to the installation of the eleventh rotating axis 170 with the second end of the first swing arm 140 and the first fixing seat 150.

[0071] refer to Figure 7 In some specific embodiments of the present invention, the first sub-groove 111 includes a first step 112 and a second step 113 extending inwardly toward both sides of the first pulley 120 respectively.

[0072] After the first pulley 120 is placed in the first sub-groove 111, the first step 112 and the second step 113 are adapted to the shape of the first pulley 120, and the first step 112 and the second step 113 play a role in limiting the first pulley 120. After the first hook 130 is set on the first pulley 120, the rest of the first sub-groove 111 is adapted to the shape of the first hook 130, and the rest of the first sub-groove 111 plays a role in limiting the first hook 130.

[0073] refer to Fig.10 In some specific embodiments of the present invention, the first swing arm 140 includes a first arm segment 141 arranged at the first end, a second arm segment 142 arranged at the second end, and a first transition arm segment 143 arranged between the first arm segment 141 and the second arm segment 142, and the plane where the first arm segment 141 is located is higher than the plane where the second arm segment 142 is located.

[0074] by Figure 4 For example, the first arm section 141 is located at the first end, the second arm section 142 is located at the second end, the first transition arm section 143 is arranged between the first arm section 141 and the second arm section 142, and the first transition arm section 143 is inclined at a certain angle, and the plane where the first arm section 141 is located is higher than the plane where the second arm section 142 is located. Through the design of the first arm section 141, the second arm section 142 and the first transition arm section 143, the overall structural strength of the first swing arm 140 can be improved, and the rotational movement of the two ends of the first swing arm 140 will not be affected.

[0075] refer to Fig.14 In some specific embodiments of the present invention, a second implementation of the sliding mechanism is provided, in which the rotation axis of the first pulley 120 and the rotation axis of the first swing arm 140 are coaxially arranged.

[0076] In some embodiments, the number of the first hooks 130 is two, and they are disposed on both sides of the rotation axis of the first pulley 120 .

[0077] Specifically, a first groove is provided on the first pulley bracket 110, and the first groove is provided with three, namely, a second sub-groove, a third sub-groove and a fourth sub-groove, and the second sub-groove and the fourth sub-groove are respectively on both sides of the third sub-groove, and the first hook 130 includes a first sub-hook and a second sub-hook, the first sub-hook is provided on the second sub-groove, the second sub-hook is provided on the fourth sub-groove, and the first pulley 120 is provided on the third sub-groove; a fifth rotation groove is provided at the center of the second sub-groove, a sixth rotation groove is provided at the center of the first sub-hook, a seventh rotation groove is provided at the center of the third sub-groove, and an eighth rotation groove is provided at the center of the first pulley 120, the first swing arm 140 is provided with a ninth rotation groove at a corresponding position of the third sub-groove, a tenth rotation groove is provided at the center of the fourth sub-groove, and an eleventh rotation groove is provided at the center of the second sub-hook, and the sliding mechanism also includes a second rotation axis, a third rotation axis and a fourth rotation axis, the second rotation axis is sequentially arranged through the fifth rotation groove and the sixth rotation groove, the third rotation axis is sequentially arranged through the ninth rotation groove, the seventh rotation groove and the eighth rotation groove, and the fourth rotation axis is sequentially arranged through the tenth rotation groove and the eleventh rotation groove. The first sub-hook can rotate around the second sub-groove, and the second sub-hook can rotate around the fourth sub-groove. When installing, only the first sub-hook and the second sub-hook need to be rotated to fix one side of the sliding mechanism. In addition, by providing the first pulley 120, friction can be reduced.

In addition, by providing the third sub-pulley and the fourth sub-pulley, friction can be reduced. The sliding mechanism of the fourth implementation only needs to provide three first grooves to accommodate two first pulleys 120 and one first hook 130, which is convenient to install, has a simplified structure, strong stability and can effectively reduce costs.

[0086] In the sliding mechanism of the fourth implementation, in order to avoid redundancy, the remaining components not mentioned and the matching relationship between the components can refer to the sliding mechanism of the first implementation.

[0088] Based on the above, specifically, the sliding mechanism also includes:

[0089] The connecting seat 300, the first pulley bracket 110 is arranged on one side of the connecting seat 300;

[0090] A second pulley bracket 210 is arranged on the other side of the connecting seat 300, and the second pulley bracket 210 is slidably arranged on the frame;

[0091] A second pulley 220 and a second hook 230, the second pulley 220 and the second hook 230 are rotatably disposed on the second pulley bracket 210 respectively;

[0092] A second swing arm 240, a first end of the second swing arm 240 can rotate around the second pulley bracket 210; and

[0093] A second fixing seat 250, which is rotatably disposed at the second end of the second swing arm 240 and is used to connect with the movable fan;

[0094] Among the rotation axis of the second pulley 220 , the rotation axis of the second hook 230 , and the rotation axis of the second swing arm 240 , at least two are coaxially arranged.

[0095] The connecting seat 300 plays a role of an intermediate connection. A group of components are designed on each side of the connecting seat 300 to achieve smooth sliding of the sliding mechanism.

[0096] The second pulley 220 and the second hook 230 are rotatably disposed on the second pulley bracket 210 , respectively. For example, the second pulley 220 and the second hook 230 are disposed at the same position and are stacked, or the second pulley 220 and the second hook 230 are disposed at different positions.

[0097] The second hook 230 can rotate around the second pulley bracket 210. When installing, only the second hook 230 needs to be rotated to fix one side of the sliding mechanism. Figure 1 and Figure 2 After the upper slide rail 7 of the frame 1 is installed, the second hook 230 is rotated to fix the second hook 230, the second pulley 220 and the second pulley bracket 210, that is, one side of the sliding mechanism is fixed.

[0098] One end of the second swing arm 240 is the first end, and the other end of the second swing arm 240 away from the first end is the second end. After one side of the sliding mechanism is fixed, the second swing arm 240 can rotate around the second pulley bracket 210. Since the second pulley 220 is arranged on the second pulley bracket 210, the friction force is reduced through the action of the second pulley 220, which helps the second swing arm 240 to rotate.

[0099] The second fixing seat 250 is disposed at the second end of the second swing arm 240. During installation, only the second fixing seat 250 needs to be fixed to fix the other side of the sliding mechanism. Figure 1 and Figure 2After the upper sash frame 8 of the movable sash 2 is attached, the second fixing seat 250 is fixed by screwing in screws, that is, the other side of the sliding mechanism is fixed. After the other side of the sliding mechanism is fixed, the second swing arm 240 can rotate around the second fixing seat 250. In combination with the above, the door or window can be opened by rotating the second swing arm 240 at the first end and the second end.

[0100] The sliding mechanism provided by the present invention comprises a second pulley bracket 210, a second pulley 220, a second hook 230, a second swing arm 240 and a second fixed seat 250, wherein the second pulley bracket 210 is slidably arranged on the frame, the second pulley 220 and the second hook 230 are rotatably arranged on the second pulley bracket 210 respectively, the first end of the second swing arm 240 can rotate around the second pulley bracket 210, the second fixed seat 250 is rotatably arranged at the second end of the second swing arm 240 and is used to connect with the movable fan, wherein at least two of the rotation axis of the second pulley 220, the rotation axis of the second hook 230 and the rotation axis of the second swing arm 240 are coaxially arranged. The sliding mechanism is easy to install, has a simplified structure, has strong stability and can effectively reduce costs.

[0101] In some specific embodiments of the present invention, the rotation axis of the second pulley 220, the rotation axis of the second hook 230, and the rotation axis of the second swing arm 240 are coaxially arranged.

[0102] Specifically, the second pulley bracket 210 is provided with a second groove, the second pulley 220 is provided on the second groove, the second hook 230 is provided on the second pulley 220, and the second hook 230 can rotate around the second pulley 220; the center of the second groove is provided with a twenty-ninth rotation groove, the center of the second pulley 220 is provided with a thirtieth rotation groove, the second swing arm 240 is provided with a thirty-first rotation groove at a corresponding position of the second groove, and the sliding mechanism further includes a twelfth rotation axis, which passes through the thirty-first rotation groove, the twenty-ninth rotation groove and the thirtieth rotation groove in sequence. The first end of the second swing arm 240 can rotate around the rotation center by setting the rotation center through the twelfth rotation axis.

[0103] The second pulley bracket 210 is provided with a second groove, and the second groove can be used to accommodate the second pulley 220. The shape of the second groove can be adapted to the shape of the second pulley 220, so that the second pulley 220 is partially or completely accommodated in the second groove. The second pulley 220 is in the shape of a cylinder, and the second groove is a circular shape with two sides cut flat. The second pulley 220 is accommodated in the second groove and partially protrudes from the second groove. In some embodiments, the second groove can also be designed to be a circular shape so that the second pulley 220 in the shape of a cylinder is fully accommodated therein.

[0104] The second groove is provided with sufficient depth to accommodate the second pulley 220 and the second hook 230 arranged on the second pulley 220. The shape of the second groove can be adapted to the shape of the second hook 230 so that the second hook 230 is partially or completely accommodated in the second groove. The second hook 230 is a circular shape with both sides cut flat, the second groove is a circular shape with both sides cut flat, the second pulley 220 is accommodated in the second groove, the second hook 230 is arranged on the second pulley 220, the second hook 230 is also accommodated in the second groove, and the second hook 230 is fully accommodated in the second groove. In some embodiments, the second hook 230 can also be designed as other shapes to partially protrude from the second groove. In some ways, the second groove can also be set to a depth that is only enough to accommodate the second pulley 220, the second hook 230 is arranged on the second pulley 220, and the second hook 230 partially or completely protrudes from the second groove.

[0105] The second hook 230 is disposed on the second pulley 220, and the second hook 230 can rotate around the second pulley 220. When installing, only the second hook 230 needs to be rotated to fix one side of the sliding mechanism. Figure 1 and Figure 2 After the upper slide rail 7 of the frame 1 is installed, the second hook 230 is rotated, so that the second hook 230, the second pulley 220 and the second pulley bracket 210 can be fixed, that is, one side of the sliding mechanism is fixed. In addition, the second hook 230 and the second pulley 220 are integrated to reduce friction and help the second hook 230 to rotate.

[0106] In some specific embodiments of the present invention, a thirty-second rotation groove is provided at the center of the second hook 230, and the twelfth rotation axis passes through the thirty-first rotation groove, the twenty-ninth rotation groove, the thirtieth rotation groove and the thirty-second rotation groove in sequence. The twelfth rotation axis can perform rotational motion. When the twelfth rotation axis rotates, since the second pulley bracket 210 is stuck in the upper slide rail 7 of the frame 1, the second pulley bracket 210 will not perform rotational motion, and the second hook 230 will perform rotational motion with the twelfth rotation axis, thereby achieving the fixation of the second hook 230. During the rotation of the second hook 230, the second pulley 220 can reduce friction and help the rotation of the second hook 230. Through the twelfth rotation axis, the rotation centers of the first end of the second swing arm 240, the second pulley 220 and the second hook 230 are on the same straight line, which is conducive to integrated design and can avoid the occurrence of rotation deviation.

[0107] In some specific embodiments of the present invention, the twelfth rotating axis includes a second base, a sixth rotating sub-axis arranged on the second base and corresponding to the position of the first end of the second swing arm 240, a seventh rotating sub-axis arranged on the sixth rotating sub-axis and corresponding to the bottom of the second groove and the position of the second pulley 220, and an eighth rotating sub-axis arranged on the seventh rotating sub-axis and corresponding to the position of the second hook 230. The sixth rotating sub-axis is circular in a cross-section perpendicular to its rotation center, the seventh rotating sub-axis is circular in a cross-section perpendicular to its rotation center, and the eighth rotating sub-axis is polygonal in a cross-section perpendicular to its rotation center, and the radius of the circular cross-section of the sixth rotating sub-axis is greater than the radius of the circular cross-section of the seventh rotating sub-axis.

[0108] The second base supports the sixth rotating sub-axis, the seventh rotating sub-axis, and the eighth rotating sub-axis. By screwing the second base, the twelfth rotating shaft can be screwed into the thirty-first rotating groove, the twenty-ninth rotating groove, the thirtieth rotating groove, and the thirty-second rotating groove. When the first end of the second swing arm 240 rotates around the second pulley bracket 210, the thirty-first rotating groove can rotate on the sixth rotating sub-axis; when the twelfth rotating shaft rotates, the friction between the eighth rotating sub-axis and the thirty-second rotating groove drives the second hook 230 to rotate.

[0109] Since the first end of the second swing arm 240 often rotates after being fixed, the radius of the circular cross section of the sixth rotating sub-axis is designed to be slightly larger, which is helpful for the rotation of the first end of the second swing arm 240. The function of the second pulley 220 is to reduce friction, so the radius of the circular cross section of the seventh rotating sub-axis is designed to be slightly smaller, and the second pulley 220 can still provide a corresponding function of reducing friction. In addition, the cross section of the eighth rotating sub-axis perpendicular to its rotation center is designed to be polygonal, in order to help drive the rotation of the second hook 230, thereby helping to fix the second hook 230.

[0110] In some specific embodiments of the present invention, the second swing arm 240 is provided with a thirty-third rotation groove at the position of the second end, the second fixed seat 250 is provided with a thirty-fourth rotation groove at the corresponding position of the second end, and the sliding mechanism further includes a thirteenth rotation axis, which is respectively connected to the thirty-third rotation groove and the thirty-fourth rotation groove. The second end of the second swing arm 240 can rotate around the second fixed seat 250, and the second fixed seat 250 is inserted into the upper fan frame 8 of the movable fan 2, and the second fixed seat 250 does not rotate. Through the thirteenth rotation axis, the rotation center of the second end of the second swing arm 240 is located on the second fixed seat 250, which is conducive to integrated design and can avoid rotation deviation.

[0111] In some specific embodiments of the present invention, the thirteenth rotating axis includes a second rotating body and a ninth rotating sub-axis and a tenth rotating sub-axis arranged on both sides of the second rotating body, the ninth rotating sub-axis corresponds to the position of the second end of the second swing arm 240, the tenth rotating sub-axis corresponds to the position of the second fixed seat 250, the second rotating body is circular in a cross-section perpendicular to its rotation center, the ninth rotating sub-axis is circular in a cross-section perpendicular to its rotation center, the tenth rotating sub-axis is circular in a cross-section perpendicular to its rotation center, and the radius of the circular cross-section of the second rotating body is greater than the radius of the circular cross-section of the ninth rotating sub-axis and the radius of the circular cross-section of the tenth rotating sub-axis.

[0112] The second rotating body supports the ninth rotating sub-axis and the tenth rotating sub-axis. When the second end of the second swing arm 240 rotates around the second fixed seat 250, the thirty-third rotating slot can rotate on the ninth rotating sub-axis. Since the second rotating body plays a supporting role, the radius of the circular cross section of the second rotating body is designed to be slightly larger to enhance the supporting role of the second rotating body. In addition, the radius of the circular cross section of the second rotating body is larger than the radius of the circular cross section of the ninth rotating sub-axis and the radius of the circular cross section of the tenth rotating sub-axis, which is also conducive to the installation of the thirteenth rotating axis with the second end of the second swing arm 240 and the second fixed seat 250.

[0113] In some specific embodiments of the present invention, the second groove includes a third step and a fourth step extending inwardly toward two sides of the second pulley 220 respectively.

[0114] After the second pulley 220 is placed in the second groove, the third step and the fourth step are adapted to the shape of the second pulley 220, and the third step and the fourth step limit the second pulley 220. After the second hook 230 is arranged on the second pulley 220, the rest of the second groove is adapted to the shape of the second hook 230, and the rest of the second groove limits the second hook 230.

[0115] In some specific embodiments of the present invention, the second swing arm 240 includes a third arm segment arranged at the first end, a fourth arm segment arranged at the second end, and a second transition arm segment arranged between the third arm segment and the fourth arm segment, and the plane where the third arm segment is located is higher than the plane where the fourth arm segment is located.

[0116] The third arm segment is located at the first end, the fourth arm segment is located at the second end, the second transition arm segment is arranged between the third arm segment and the fourth arm segment, and the second transition arm segment is inclined at a certain angle, and the plane where the third arm segment is located is higher than the plane where the fourth arm segment is located. Through the design of the third arm segment, the fourth arm segment and the second transition arm segment, the overall structural strength of the second swing arm 240 can be improved, and the rotational movement of the two ends of the second swing arm 240 will not be affected.

[0117] It is worth mentioning that the above-mentioned components arranged on both sides of the connecting seat 300 adopt the design of the sliding mechanism of the first implementation method. In other embodiments, the design of the sliding mechanism of the second implementation method may also be adopted, the design of the sliding mechanism of the third implementation method may also be adopted, the design of the sliding mechanism of the fourth implementation method may also be adopted, or a combination of two of the first implementation method, the second implementation method, the third implementation method and the fourth implementation method may also be adopted.
