[0037] The following is for reference. Figures 1 to 7 This invention describes a ventilation window blade fixing fixture according to an embodiment of the present invention.

[0038] like Figures 1 to 3 As shown, the ventilation window blade fixing fixture according to an embodiment of the present invention includes a base 100, a support component, and a clamping component. The support component includes at least one support module 200 detachably mounted to the base 100. The upper part of the support module 200 is provided with a contoured structure that matches the lower end face of the ventilation window blade 900 and is used to place the ventilation window blade 900. The clamping component includes clamping modules 300 that are disposed on the base 100 corresponding to the support modules 200. The clamping module 300 is provided with a clamping head 310 and a clamping handle 320 that can drive the clamping head 310. The clamping head 310 is detachably disposed on the clamping module 300. The clamping handle 320 can be rotated to a first position that allows the clamping head 310 to be clamped to the upper end face of the ventilation window blade 900 and a second position that allows the clamping head 310 to be moved away from the upper end face of the ventilation window blade 900.

[0039] The ventilation window blade 900 is stably supported by the contoured structure of the support module 200. The clamping module 300, which is configured corresponding to the support module 200, can clamp the ventilation window blade 900 onto the support module 200, thereby fixing the ventilation window blade 900 well and facilitating the processing of the ventilation window blade 900. Both the support module 200 and the clamping head 310 are detachable and replaceable structures, which can be replaced according to different ventilation window blades 900, and can be adapted to ventilation window blades 900 of different specifications, improving versatility. The ventilation window blade 900 can be clamped or loosened by the clamping handle 320, making it convenient to use.

[0040] In some embodiments of this utility model, the clamping head 310 can be selected with different shapes according to different ventilation window blades 900. Specifically, the clamping head 310 can be spherical, cylindrical, inverted V-shaped, etc., to match the arc structure, planar structure, inverted V-shaped structure, etc. of the upper end surface of the ventilation window blade 900, so that the clamping module 300 can clamp the ventilation window blade 900 more stably.

[0041] In some embodiments of this utility model, the pressing head 310 is an elastic body, such as being made of elastic material, such as rubber, silicone, etc., or the pressing head 310 is an elastic mechanism, such as a spring or a movable block with a spring, to elastically press the ventilation window blade 900, reducing the occurrence of damage to the ventilation window blade 900.

[0042] In some embodiments of this utility model, the clamping module 300 further includes a clamping arm 330, which is provided with a sliding mechanism 340 that can slide along its length. The clamping head 310 is detachably installed to the sliding mechanism 340. The position of the clamping head 310 can be adjusted through the sliding mechanism 340 to adapt to different clamping positions and improve versatility.

[0043] Specifically, in practical applications, the position where each blade can be pressed or matched with the pressing head 310 may vary. By adjusting the position of the pressing head 310, the pressing requirements of different positions can be met.

[0044] like Figure 3 , Figure 4 As shown, in some embodiments of this utility model, the sliding mechanism 340 includes a slide rod 341, a first nut 342, and a second nut 343. The pressure arm 330 is provided with a groove 344 extending along its length. The slide rod 341 can pass through the groove 344 from top to bottom and can extend along the length of the groove 344. The first nut 342 and the second nut 343 are respectively connected to the upper and lower ends of the slide rod 341 by threaded engagement and can press against the pressure arm 330. The pressing head 310 is detachably installed at the lower end of the slide rod 341. By loosening the first nut 342 and / or the second nut 343, the slide rod 341 can be slid, thereby adjusting the position of the pressing head 310.

[0045] Specifically, the middle part of the slide bar 341 is a smooth rod structure, and the two ends are external threaded structures. The slide groove 344 extends along the lateral direction of the ventilation window blade 900, so that the pressing head 310 can slide close to or away from the ventilation window blade 900 to adjust the pressing position of the pressing head 310.

[0046] It is understood that in some embodiments of this utility model, the sliding mechanism 340 may also be a guide rod and slider mechanism. For example, a guide rod with a square cross section and a slider sleeved on the guide rod may be provided. The slider may be equipped with a pressing screw to press the guide rod to position the slider. The pressing head 310 may be detachably connected to the slider and may also satisfy the position adjustment function of the pressing head 310.

[0047] like Figure 4 As shown, in some embodiments of this utility model, the clamping head 310 is detachably installed to the lower end of the slide rod 341 through a threaded connection structure, thereby realizing the detachable installation of the clamping head 310.

[0048] Specifically, the clamping head 310 is a rubber part with a nut embedded inside. The lower end of the slide rod 341 is provided with an external thread structure corresponding to the nut. When disassembling or assembling, simply rotate the clamping head 310.

[0049] Of course, in the specific implementation process, the clamping head 310 can also be detachably installed to the slide bar 341 through a plug-in mating structure, a snap-fit ​​mechanism, etc., which will not be described in detail here.

[0050] like Figure 4 As shown, in some embodiments of this utility model, the first nut 342 and the second nut 343 are respectively provided with anti-rotation washers 345 to reduce the wear on the pressure arm 330 when the first nut 342 and the second nut 343 rotate.

[0051] Specifically, the anti-rotation pad 345 has ears on both sides extending toward the pressure arm 330. The ears can abut against the side of the pressure arm 330, thereby restricting the rotation of the anti-rotation pad 345.

[0052] like Figure 4 , Figure 5 and Figure 6 As shown, in some embodiments of this utility model, the clamping module 300 further includes a clamping arm 330, a connecting arm 350, and a rotating base 360. The lower end of the clamping handle 320 is rotatably connected to the first shaft hole 361 at the front of the rotating base 360 ​​via a first rotating shaft 321. The rear of the rotating base 360 ​​is rotatably connected to the second shaft hole 331 at the rear of the clamping arm 330 via a second rotating shaft 362. The clamping head 310 is installed at the front end of the clamping arm 330. One end of the connecting arm 350 is rotatably connected to the clamping arm 330 via a third rotating shaft 351. The third shaft hole 332 is located in front of the second shaft hole 331 (on the side near the ventilation window blade 900). The other end of the connecting arm 350 is rotatably connected to the fourth shaft hole 322 on the upper part of the clamping handle 320 through the fourth rotating shaft 352, so that the clamping handle 320, the clamping arm 330, the connecting arm 350 and the rotating seat 360 form a four-bar linkage mechanism. When the clamping handle 320 rotates, it can deform the four-bar linkage mechanism to change the position of the clamping head 310, thereby clamping or loosening the ventilation window blade 900.

[0053] Specifically, such as Figure 3 , Figure 5 As shown, the side biased towards the ventilation window blade 900 is defined as the front, and the side biased towards the clamping module 300 is defined as the rear.

[0054] like Figure 4 As shown, in some embodiments of this utility model, a cavity is provided in the middle of the clamping handle 320 to accommodate the connecting arm 350 and improve the compactness of the structure.

[0055] Specifically, the clamping handle 320 is formed by welding or fastening two curved ribs, with the cavity described above formed between the two curved ribs.

[0056] In some embodiments of this utility model, the gripping end of the pressing handle 320 is provided with a soft rubber sleeve or a hard plastic sleeve to improve the gripping feel.

[0057] It is understood that in some embodiments of this utility model, the clamping handle 320 can also drive the clamping head 310 to move through a linkage slider mechanism. For example, if the clamping head 310 is set on a slider, the clamping handle 320 can also drive the clamping head 310 by configuring a linkage and slider to form a linkage slider structure.

[0058] like Figure 5 As shown, in some embodiments of this utility model, when the clamping handle 320 is in the first position, the clamping handle 320 is in a vertical state, and the two rotating connection points of the connecting arm 350 are distributed vertically, so that the force directions of the clamping handle 320 and the connecting arm 350 are coincident or parallel, which can keep the four-bar linkage in a relatively stable state, so that the clamping handle 320 can be stably kept in the first position, and the clamping head 310 can keep the ventilation window blade 900 pressed.

[0059] Specifically, when the clamping handle 320 is in the first position, the clamping arm 330 is in a horizontal state, and the clamping handle 320 and the connecting arm 350 (the line connecting the two rotating connection points) are both perpendicular to the clamping arm 330, so that the four-bar linkage is in a relatively stable self-locking state, so that the clamping head 310 keeps pressing the ventilation window blade 900.

[0060] It is understood that in some embodiments of this utility model, the clamping module 300 may also be configured with a locking mechanism, such as a pin mechanism, to lock the clamping handle 320 in a first position, and may also keep the clamping head 310 clamping the ventilation window blade 900.

[0061] like Figure 5 As shown, in some embodiments of this utility model, the connecting arm 350 is provided with a pressing part 353. When the pressing handle 320 is in the first position, the pressing part 353 presses against the pressing arm 330 to improve the pressing effect on the pressing arm 330.

[0062] Specifically, the pressing part 353 is offset from the line connecting the two rotating connection points of the connecting arm 350 and faces the side closer to the pressing head 310, thereby increasing the pressing force on the pressing arm 330.

[0063] like Figure 4 , Figure 5 and Figure 6As shown, in some embodiments of this utility model, the rotary base 360 ​​is provided with a limiting part 363 that can limit the clamping handle 320 to a second position, so as to prevent the clamping handle 320 from being over-rotated and damaging the clamping module 300.

[0064] like Figures 1 to 3 As shown, in some embodiments of this utility model, the clamping module 300 is mounted to the base 100 via a mounting base 370. The mounting base 370 is mounted to the base 100 via a first bolt mechanism. The base 100 is provided with an arc-shaped hole 101 that cooperates with the first bolt mechanism. After the first bolt mechanism is loosened, the clamping module 300 can be rotated relative to the base 100 through the cooperation between the first bolt mechanism and the arc-shaped hole 101, thereby rotating and adjusting the clamping head 310 to adapt to different clamping positions.

[0065] Specifically, the cooperation between the first bolt mechanism and the arc-shaped hole 101 enables the clamping module 300 to rotate, thereby allowing the clamping head 310 to deflect to the lateral position of the clamping module 300.

[0066] like Figure 2 As shown, in some embodiments of this utility model, the clamping module 300 further includes a rotating base 360. The rotating base 360 ​​is installed to the mounting base 370 by a second bolt mechanism. The mounting base 370 is provided with an elongated hole 371 that cooperates with the second bolt mechanism. After the second bolt mechanism is loosened, the clamping module 300 can slide along the length direction of the elongated hole 371 through the cooperation between the second bolt mechanism and the elongated hole 371, thereby adjusting the position of the clamping head 310 to adapt to different clamping positions.

[0067] Specifically, the elongated hole 371 extends along the lateral direction of the ventilation window blade 900, allowing the clamping module 300 to slide closer to or further away from the ventilation window blade 900 to adjust the clamping position of the clamping head 310.

[0068] like Figure 2 As shown, in some embodiments of this utility model, the support module 200 is provided with a plug-in part 201, and the base 100 is provided with a plug-in hole 102 that can be plugged into the plug-in part 201. The support module 200 is detachably installed to the base 100 through the plug-in part 201 and the plug-in hole 102, so as to realize the detachable installation of the support module 200 and facilitate disassembly and assembly.

[0069] Specifically, the support module 200 is assembled from multiple support plates. The insertion part 201 is located on the bottom of the support plate. After the insertion part 201 is inserted into the insertion hole 102, the support module 200 is temporarily placed on the base 100. After the ventilation window blade 900 is placed on the support module 200, the pressing module 300 presses the ventilation window blade 900 to form a stable pressing and fixing structure.

[0070] It is understood that in some embodiments of this utility model, the support module 200 can also be detachably installed to the base 100 via screw mechanisms, snap-fit ​​mechanisms, etc.

[0071] like Figure 2 As shown, in some embodiments of this utility model, the insertion hole 102 is a through hole, and the insertion part 201 can be inserted into the lower end face of the base 100 through the insertion hole 102. The insertion part 201 is made of magnetic material, and the lower end face of the base 100 is provided with a magnetic plate 110 that can be magnetically fixed with the insertion part 201 to improve the temporary fixing effect of the support module 200.

[0072] Specifically, the base 100 is made of a magnetic material such as iron, and the magnetic plate 110 can be magnetically fixed to the lower end face of the base 100 at the position corresponding to the insertion hole 102, so as to facilitate the magnetic fixation of the insertion part 201.

[0073] like Figure 7 As shown, in some embodiments of this utility model, the support module 200 includes a first support plate 210 and a second support plate 220 spaced apart from the first support plate 210. The first support plate 210 and the second support plate 220 are connected by a connecting mechanism. A contoured structure is provided on the upper part of the first support plate 210 and the second support plate 220, thereby forming a support structure for the ventilation window blade 900. The spaced first support plate 210 and the second support plate 220 can form a support structure with a set span for the ventilation window blade 900, thereby improving the support effect.

[0074] It is understood that in some embodiments of this utility model, a support plate may be provided between the first support plate 210 and the second support plate 220 to increase support points and improve the support effect.

[0075] like Figure 7 As shown, in some embodiments of this utility model, the connecting mechanism includes a pull rod 231, a sleeve 232, and a third nut 233. The first support plate 210 and the second support plate 220 are both provided with connecting holes 211 through which the pull rod 231 can pass. The sleeve 232 is located between the first support plate 210 and the second support plate 220 and corresponds to the connecting holes 211. The pull rod 231 passes through the two connecting holes 211 and the sleeve 232 located between the two connecting holes 211. One end of the pull rod 231 is a limiting head 234 that cannot pass through the connecting holes 211. The other end of the pull rod 231 is connected to and locked with the third nut 233, which can tighten the first support plate 210 and the second support plate 220 to form a relatively stable support module 200. The structure is simple and reasonable.

[0076] Specifically, the first support plate 210 and the second support plate 220 can be formed by directly stamping metal sheets, and the above-mentioned connecting hole 211 and contour structure can be formed directly. The production and processing are convenient, the cost is low, and the replacement is also very convenient after damage.

[0077] It is understood that in some embodiments of this utility model, the support module 200 can also be a support block with a set width and a contoured structure, which can also provide good support for the ventilation window blades 900.

[0078] like Figure 7 As shown, in some embodiments of this utility model, the outer diameter of the limiting head 234 extends outward from the pull rod 231 along the length direction of the pull rod 231, and the outer diameter of the limiting head 234 gradually expands outward from the pull rod 231, that is, the limiting head 234 has a conical frustum structure, so as to improve the matching effect between the limiting head 234 and the connecting hole 211 and improve the structural stability of the supporting module 200.

[0079] Specifically, when the third nut 233 is tightened, the limiting head 234 is partially pulled into the connecting hole 211. Through the limiting head 234, which has a conical frustum structure, the limiting head 234 can form a relatively tight fit with the inner wall of the connecting hole 211, reducing gaps, improving the compactness of the support module 200 structure, and reducing the occurrence of offset of the first support plate 210 and / or the second support plate 220.

[0080] In some embodiments of this utility model, the contouring structure may be one or more of the following: slots, V-shaped grooves, inverted V-shaped protrusions, arc-shaped grooves, arc-shaped protrusions, etc., provided on the upper part of the first support plate 210 and the second support plate 220, to adapt to different ventilation window blades 900.

[0081] It is conceivable that in some embodiments of this utility model, multiple sleeves 232 can be configured, and multiple middle support plates can be set between the first support plate 210 and the second support plate 220. The support plates and sleeves 232 are alternately arranged and the connecting hole 211 is aligned with the sleeve 232. After the pull rod 231 is inserted, the third nut 233 is locked to form a support module 200 with multiple support plates, so as to achieve a better support effect.

[0082] It is understood that in some embodiments of this utility model, the connecting mechanism may also be a riveting mechanism, a snap-fit ​​mechanism, etc. For example, the connecting mechanism may be equipped with a snap-fit ​​plate, and the snap-fit ​​plate may be provided with snap-fit ​​holes. The first support plate 210 and the second support plate 220 may be snapped into the snap-fit ​​holes, which may also achieve the fixation of the first support plate 210 and the second support plate 220.
