[0048] Reference Figures 4-6 The utility model embodiment provides a sliding mechanism, comprising:

[0049] The first pulley support 110 is slidably arranged on the frame;

[0050] The first pulley 120 and the first hook 130 are rotatably arranged on the first pulley support 110, respectively;

[0051] The first swing arm 140 has a first end rotatable about the first pulley support 110; and

[0052] The first fixed seat 150 is rotatably arranged at the second end of the first swing arm 140 and used for connecting with the movable fan;

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

[0054] The first pulley 120 and the first hook 130 are rotatably arranged on the first pulley support 110, for example, the first pulley 120 and the first hook 130 are arranged at the same position and stacked, or the first pulley 120 and the first hook 130 are arranged at different positions.

[0055] The first hook 130 can rotate around the first pulley support 110, so when installing, only the first hook 130 needs to be rotated to fix one side of the sliding mechanism. For example, after the first pulley support 110 is clamped into the upper sliding rail 7 of the frame 1 as shown in Figure 1 and Figure 2 , rotating the first hook 130 can fix the first hook 130, the first pulley 120 and the first pulley support 110, that is, fix one side of the sliding mechanism.

[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 fixing one side of the sliding mechanism, the first swing arm 140 can rotate around the first pulley support 110. Since the first pulley 120 is arranged on the first pulley support 110, through the action of the first pulley 120, the friction is reduced, which helps the rotation of the first swing arm 140.

[0057] The first fixed seat 150 is arranged at the second end of the first swing arm 140, and when installing, only the first fixed seat 150 needs to be fixed to fix the other side of the sliding mechanism. For example, after the first fixed seat 150 is clamped into the upper fan frame 8 of the movable fan 2 as shown in Figure 1 and Figure 2 , the first fixed seat 150 is fixed by screwing, that is, the other side of the sliding mechanism is fixed. After fixing the other side of the sliding mechanism, the first swing arm 140 can rotate around the first fixed seat 150. In combination with the above, through the rotation of the first swing arm 140 at the first end and the second end, the door or window can be opened.

[0058] The sliding mechanism provided by the utility model is convenient to install, simplifies the structure, is strong in stability and can effectively reduce the cost.

[0059] Reference Figures 4-8 、 Figure 10 In some specific embodiments of the utility model, the first rotating shaft of the first pulley, the rotating shaft of the first hook and the rotating shaft of the first swing arm are coaxially arranged.

[0060] Specifically, the first pulley support 110 is provided with a first groove, the first groove is provided with one, which is a first sub-groove 111, the first pulley 120 is arranged on the first sub-groove 111, the first hook 130 is arranged 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 rotating groove 1111, the center of the first pulley 120 is provided with a second rotating groove 121, the first swing arm 140 is provided with a third rotating groove 1411 at the corresponding position of the first sub-groove 111, and the sliding mechanism further comprises a first rotating shaft 160, the first rotating shaft 160 is arranged in sequence through the third rotating groove 1411, the first rotating groove 1111 and the second rotating groove 121. The first end of the first swing arm 140 can rotate around the rotating center through the first rotating shaft 160. The sliding mechanism of the first implementation mode integrates the first pulley 120 and the first hook 130 together, only one first pulley 120 and first hook 130 are needed to realize fixation, which is convenient to install, simplifies the structure, is strong in stability and can effectively reduce the cost.

[0061] Reference Figure 7 The first pulley support 110 is provided with the first sub-groove 111, and the first sub-groove 111 can be used for accommodating the first pulley 120. The shape of the first sub-groove 111 can be matched with the shape of the first pulley 120, so that the first pulley 120 is partially or wholly 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 similar circle with two sides cut off, 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 in the shape of a circle, so that the first pulley 120 in the shape of a cylinder is entirely accommodated therein.

[0062] With reference to Figure 7 , the first sub-groove 111 is provided with sufficient depth to accommodate the first pulley 120 and the first hook 130 arranged 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 entirely accommodated in the first sub-groove 111. In combination Figure 4 、 Figure 7 and Figure 9 , the first hook 130 is in the shape of a similar circle with two sides cut off, the first sub-groove 111 is in the shape of a similar circle with two sides cut off, 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 entirely accommodated in the first sub-groove 111. In some embodiments, the first hook 130 can also be designed in other shapes to partially protrude from the first sub-groove 111. In some embodiments, the first sub-groove 111 can also be provided with a depth sufficient to accommodate only the first pulley 120, the first hook 130 is arranged on the first pulley 120, and the first hook 130 partially or entirely protrudes from the first sub-groove 111.

[0063] The first hook 130 is arranged on the first pulley 120, and the first hook 130 can rotate around the first pulley 120, so that when installed, only the first hook 130 needs to be rotated to achieve the fixation of one side of the sliding mechanism. For example, after the first pulley bracket 110 is clamped into the upper slide rail 7 of the frame 1 as shown in Figure 1 and Figure 2 , rotating the first hook 130 can achieve the fixation of the first hook 130, the first pulley 120 and the first pulley bracket 110, i.e. the fixation of one side of the sliding mechanism. In addition, the first hook 130 and the first pulley 120 are integrated, which reduces the friction and helps the rotation of the first hook 130.

[0064] With reference to Figures 4-6 、 Figure 9In some specific embodiments of the utility model, the center of first hook 130 is provided with fourth rotating groove 131, first rotating shaft 160 is sequentially arranged through third rotating groove 1411, first rotating groove 1111, second rotating groove 121 and fourth rotating groove 131. First rotating shaft 160 can rotate, when first rotating shaft 160 rotates, because first pulley support 110 is clamped into upper slide rail 7 of frame 1, first pulley support 110 will not rotate, and first hook 130 will rotate with first rotating shaft 160, so that the fixation of first hook 130 is realized. In the rotating process of first hook 130, first pulley 120 can reduce friction, which is helpful for the rotation of first hook 130. Through first rotating shaft 160, the rotation center of first end of first swing arm 140, first pulley 120 and first hook 130 is on the same straight line, which is conducive to integrated design, and can avoid the situation of rotation deviation.

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

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

[0067] Since the first end of the first swing arm 140 is always in rotational motion after being fixed, the radius of the circular cross section of the first rotating sub-shaft 162 is designed to be slightly larger, which helps the rotation of the first end of the first swing arm 140. The first pulley 120 serves to reduce friction, so the radius of the circular cross section of the second rotating sub-shaft 163 is designed to be slightly smaller, and the first pulley 120 can still provide the corresponding function of reducing friction. In addition, the third rotating sub-shaft 164 is designed as a polygon in the cross section perpendicular to its rotation center, which helps to drive the rotation of the first hook 130, and further helps to fix the first hook 130.

[0068] With reference to Figures 4-6 , Figure 10 and Figure 11 , in some specific embodiments of the present application, the first swing arm 140 is provided with a twenty-seventh rotating groove 1421 at the position of the second end, and the first fixed seat 150 is provided with a twenty-eighth rotating groove 151 at the corresponding position of the second end, and the sliding mechanism further comprises an eleventh rotating shaft 170, which is connected to the twenty-seventh rotating groove 1421 and the twenty-eighth rotating 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 clamped into the upper frame 8 of the movable fan 2, so the first fixed seat 150 will not rotate. Through the eleventh rotating 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 the occurrence of rotational deviation.

[0069] With reference to Figure 13 , in some specific embodiments of the present application, the eleventh rotating shaft 170 comprises a first rotating body 171 and fourth and fifth rotating sub-shafts 172 and 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 the cross section perpendicular to its rotation center, the fourth rotating sub-shaft 172 is circular in the cross section perpendicular to its rotation center, and the fifth rotating sub-shaft 173 is circular in the cross section perpendicular to its rotation center, 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-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-shaft 172 and the fifth rotating sub-shaft 173. When the second end of the first swing arm 140 rotates around the first fixed seat 150, the twenty-seventh rotating groove 1421 can rotate on the fourth rotating sub-shaft 172. Since the first rotating body 171 provides support, the radius of its circular cross-section is designed to be slightly larger to enhance its supporting function. Furthermore, the radius of the circular cross-section of the first rotating body 171 is larger than the radii of the circular cross-sections of the fourth rotating sub-shaft 172 and the fifth rotating sub-shaft 173, which also facilitates the installation of the eleventh rotating shaft 170 with the second end of the first swing arm 140 and the first fixed seat 150.

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

[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 limit the movement of the first pulley 120. After the first hook 130 is set on the first pulley 120, the remaining part of the first sub-groove 111 is adapted to the shape of the first hook 130, and the remaining part of the first sub-groove 111 limits the movement of the first hook 130.

[0073] refer to Figure 10 In some specific embodiments of this utility model, the first swing arm 140 includes a first arm segment 141 disposed at a first end, a second arm segment 142 disposed at a second end, and a first transition arm segment 143 disposed between the first arm segment 141 and the second arm segment 142. 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 segment 141 is located at the first end, the second arm segment 142 is located at the second end, and the first transition arm segment 143 is located between the first arm segment 141 and the second arm segment 142, with the first transition arm segment 143 having a certain tilt angle. The plane where the first arm segment 141 is located is higher than the plane where the second arm segment 142 is located. Through the design of the first arm segment 141, the second arm segment 142, and the first transition arm segment 143, the overall structural strength of the first swing arm 140 can be improved without affecting the rotational movement at both ends of the first swing arm 140.

[0075] refer to Figure 14 In some specific embodiments of this utility model, a second implementation of the sliding mechanism is provided, wherein 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 the two first hooks 130 are arranged on both sides of the rotating shaft of the first pulley 120.

The first sub-hook can rotate around the second sub-groove, and the second sub-hook can rotate around the fourth sub-groove, so that when installed, only the first sub-hook and the second sub-hook need to be rotated to fix one side of the sliding mechanism. By arranging the first pulley 120, the friction force can be reduced. The sliding mechanism of the second implementation manner can accommodate two first hooks 130 and one first pulley 120 only by arranging three first grooves, and is convenient to install, simplifies the structure, is stable, and can effectively reduce the cost.

[0078] In the sliding mechanism of the second implementation manner, to avoid redundancy, the remaining components and the cooperation relationship between the components can be referred to the sliding mechanism of the first implementation manner.

The first end of the second swing arm 240 is rotatable around the rotation center of the 12th rotation shaft.

[0103] The second pulley bracket 210 is provided with a second groove, and the second groove can be used for accommodating the second pulley 220. The shape of the second groove can be matched with the shape of the second pulley 220, so that the second pulley 220 is partially or entirely accommodated in the second groove. The second pulley 220 is in the shape of a cylinder, the second groove is in the shape of a circle with two sides cut flat, and 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 in the shape of a circle, so that the second pulley 220 in the shape of a cylinder is entirely 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 matched with the shape of the second hook 230, so that the second hook 230 is partially or entirely accommodated in the second groove. The second hook 230 is a shape similar to a circle with two sides cut flat, the second groove is a shape similar to a circle with two 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 entirely accommodated in the second groove.

[0105] The second hook 230 is arranged on the second pulley 220, and the second hook 230 can rotate around the second pulley 220, so that when installed, only the second hook 230 needs to be rotated to achieve the fixation of one side of the sliding mechanism. For example, after the second pulley bracket 210 is clamped into the upper slide rail 7 of the frame 1 as shown in FIGS. 1 and 2, the second hook 230 is rotated to achieve the fixation of the second hook 230, the second pulley 220 and the second pulley bracket 210, that is, the fixation of one side of the sliding mechanism. In addition, the second hook 230 and the second pulley 220 are integrated to reduce friction, which helps the rotation of the second hook 230. Figure 1 and Figure 2 The second hook 230 is arranged on the second pulley 220, and the second hook 230 can rotate around the second pulley 220, so that when installed, only the second hook 230 needs to be rotated to achieve the fixation of one side of the sliding mechanism. For example, after the second pulley bracket 210 is clamped into the upper slide rail 7 of the frame 1 as shown in FIGS. 1 and 2, the second hook 230 is rotated to achieve the fixation of the second hook 230, the second pulley 220 and the second pulley bracket 210, that is, the fixation of one side of the sliding mechanism. In addition, the second hook 230 and the second pulley 220 are integrated to reduce friction, which helps the rotation of the second hook 230.

[0106] In some specific embodiments of the present application, the center of the second hook 230 is provided with a thirty-second rotating groove, and a twelfth rotating shaft is sequentially arranged through the thirty-first rotating groove, the twenty-ninth rotating groove, the thirtieth rotating groove and the thirty-second rotating groove. The twelfth rotating shaft can rotate, and when the twelfth rotating shaft rotates, since the second pulley bracket 210 is clamped into the upper slide rail 7 of the frame 1, the second pulley bracket 210 will not rotate, but the second hook 230 will rotate with the twelfth rotating shaft, thereby achieving the fixation of the second hook 230. During the rotation of the second hook 230, the second pulley 220 can reduce friction, which helps the rotation of the second hook 230. Through the twelfth rotating shaft, the first end of the second swing arm 240, the second pulley 220 and the rotation center of 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 utility model, twelfth rotation axis includes second base, sixth rotation sub shaft is established in second base and corresponds to the position of first end of second swing arm 240, seventh rotation sub shaft is established in sixth rotation sub shaft and corresponds to the position of second groove bottom and second pulley 220, eighth rotation sub shaft is established in seventh rotation sub shaft and corresponds to the position of second hook 230, the section perpendicular to the rotation center of sixth rotation sub shaft is circular, the section perpendicular to the rotation center of seventh rotation sub shaft is circular, the section perpendicular to the rotation center of eighth rotation sub shaft is polygon, the radius of the circular section of sixth rotation sub shaft is greater than the radius of the circular section of seventh rotation sub shaft.

[0108] Second base supports sixth rotation sub shaft, seventh rotation sub shaft and eighth rotation sub shaft, and by screwing second base, twelfth rotation axis can be screwed into thirty-first rotation groove, twenty-ninth rotation groove, thirtieth rotation groove and thirty-second rotation groove, when first end of second swing arm 240 rotates around second pulley support 210, thirty-first rotation groove can rotate on sixth rotation sub shaft, and when twelfth rotation axis rotates, second hook 230 is driven to rotate by the friction force between eighth rotation sub shaft and thirty-second rotation groove.

[0109] Since first end of second swing arm 240 rotates constantly after being fixed, the radius of the circular section of sixth rotation sub shaft is designed slightly larger, which helps the rotation of first end of second swing arm 240, and since second pulley 220 reduces friction, the radius of the circular section of seventh rotation sub shaft is designed slightly smaller, and second pulley 220 still can provide corresponding friction-reducing effect, and eighth rotation sub shaft is designed as a polygon in the section perpendicular to its rotation center, which helps the rotation of second hook 230 and then helps the fixation of second hook 230.

[0110] In some specific embodiments of the utility model, third thirty-three rotation groove is arranged at the position of second end of second swing arm 240, third thirty-four rotation groove is arranged at the corresponding position of second end of second fixed base 250, and thirteenth rotation axis is connected to third thirty-three rotation groove and third thirty-four rotation groove, second end of second swing arm 240 can rotate around second fixed base 250, and second fixed base 250 is clamped into upper frame 8 of movable fan 2, so second fixed base 250 does not rotate, and through thirteenth rotation axis, the rotation center of second end of second swing arm 240 is located on second fixed base 250, which is conducive to integrated design and can avoid rotation deviation.

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

[0112] The second rotating main body supports the ninth rotating sub-shaft and the tenth rotating sub-shaft. When the second end of the second swing arm 240 rotates around the second fixed seat 250, the thirty-third rotating groove can rotate on the ninth rotating sub-shaft. Because the second rotating main body has a supporting effect, the radius of the circular cross section of the second rotating main body is slightly larger, so as to improve the supporting effect of the second rotating main body. In addition, the radius of the circular cross section of the second rotating main body is greater than the radius of the circular cross section of the ninth rotating sub-shaft and the radius of the circular cross section of the tenth rotating sub-shaft, which is also conducive to the installation of the thirteenth rotating shaft, the second end of the second swing arm 240 and the second fixed seat 250.

[0113] In some specific embodiments of the utility model, the second groove includes a third step and a fourth step extending inwardly to both 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 matched with 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 remaining part of the second groove is matched with the shape of the second hook 230, and the remaining part of the second groove limits the second hook 230.

[0115] In some specific embodiments of the utility model, 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 has a certain inclination 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 structural strength of the second swing arm 240 as a whole 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 components arranged on both sides of the connecting seat 300 adopt the design of the sliding mechanism of the first implementation manner, and in other embodiments, the design of the sliding mechanism of the second implementation manner can also be adopted, the design of the sliding mechanism of the third implementation manner can also be adopted, the design of the sliding mechanism of the fourth implementation manner can also be adopted, or the design of the combination of two of the first implementation manner, the second implementation manner, the third implementation manner, and the fourth implementation manner can also be adopted.
