[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a blowing damper connecting rod, such as Figures 1-5 As shown, the device includes a housing 1. A connecting shaft 11 is rotatably connected to the inner wall of the housing 1. A guide plate 101 is fixed to the outer wall of the connecting shaft 11. A support block 12 is bolted to the outer wall of the housing 1. A motor 13 is fixed to the top of the outer wall of the support block 12. A turntable 14 is fixed to the output end of the motor 13. An adjustment assembly is provided on the side wall of the turntable 14. A first connecting rod 15 is installed on the side wall of the adjustment assembly. A second connecting rod 16 is rotatably connected to the outer wall of the first connecting rod 15. A fixing frame 17 is fixed to the outer wall of the housing 1. The second connecting rod 16 is slidably contacted on the inner wall of the fixing frame 17. A rack 18 is fixed to the side wall of the second connecting rod 16. A semi-circular gear 19 is fixed to the side wall of the connecting shaft 11. A support plate 10 is fixed to the side wall of the housing 1. The support plate 10 is in contact with the rack 18.

[0028] When the equipment is working, the motor 13 is started, which drives the turntable 14 to rotate. The turntable 14 drives the first connecting rod 15 to rotate, causing the first connecting rod 15 to pull and push the second connecting rod 16. The second connecting rod 16 moves horizontally under the restriction of the fixed frame 17. At this time, the rack 18 drives the connecting shaft 11 to rotate at a certain angle through the semi-arc gear 19. The air flows outward along the guide plate 101. Through the rack 18 and the semi-arc gear 19, the equipment can regularly sweep the air up and down, reducing the discomfort caused to the user by blowing air at a single angle for a long time and increasing the user's comfort.

[0029] like Figure 2 and Figure 3As shown, a pair of fixing blocks 2 are fixed to the outer wall of the housing 1, a fixing post 21 is fixed to the inner wall of the fixing block 2, a connecting block 22 is slidably contacted to the outer wall of the fixing post 21, a slider 23 is fixed to the top of the outer wall of the connecting block 22, a rack 18 is fixed to the top of the outer wall of the slider 23, and a groove 24 is opened on the side wall of the support plate 10, and the slider 23 is slidably contacted to the groove 24.

[0030] When the equipment is working, the rack 18 moves horizontally, which drives the slider 23 to move. The connecting block 22 also slides under the restriction of the fixed column 21. The fixed column 21 and the connecting block 22 can also provide additional support for the support plate 10. By setting the slider 23 and the fixed column 21, the stability of the rack 18 during operation is increased, the probability of the rack 18 or the support plate 10 tilting during long-term operation is reduced, and the failure rate of the equipment is reduced.

[0031] like Figure 4 As shown, the adjustment assembly includes a connecting column 3, a connecting hole 31, a fixing bolt 32, and a weight reduction groove 33. The connecting column 3 is rotatably connected to the inner side wall of the first connecting rod 15. Several connecting holes 31 are opened on the side wall of the turntable 14. The fixing bolt 32 is threadedly connected to the side wall of the turntable 14. The fixing bolt 32 is slidably connected to the connecting column 3. Several weight reduction grooves 33 are opened on the side wall of the turntable 14.

[0032] Before installation, staff can adjust the equipment in advance by connecting the connecting column 3 to the appropriate connecting hole 31 and screwing the fixing bolt 32 into the turntable 14 until the fixing bolt 32 penetrates the connecting column 3. When the connecting column 3 is in different connecting holes 31, the distance that the first connecting rod 15 will follow the rotation will change when the turntable 14 rotates. The fixing bolt 32 and the connecting column 3 make it easy for staff to adjust the equipment in advance according to the situation.

[0033] like Figure 3 As shown, several brush plates 4 are fixed to the side wall of the housing 1, and several bristles 41 are fixed to the bottom of the outer side wall of the brush plates 4. The bristles 41 are in contact with the rack 18.

[0034] When the equipment is working, as the rack 18 moves, the bristles 41 will rub against the rack 18. The bristles 41 will clean the dust and impurities attached to the side wall of the rack 18. By setting the bristles 41, the probability of failure in the fit between the rack 18 and the semi-circular gear 19 caused by dust and impurities is reduced, and the stability of the equipment during operation is increased.

[0035] like Figure 1 and Figure 5 As shown, a contact block 5 is fixed to the side wall of the housing 1, and a buffer pad 51 is fixed to the side wall of the rack 18.

[0036] When the equipment is working, the contact block 5 limits the maximum position of the rack 18. When the equipment malfunctions, if the rack 18 is pushed beyond a certain range, the buffer pad 51 will contact the contact block 5. The contact block 5 limits the position of the buffer pad 51, thereby limiting the range of movement of the rack 18. By setting the contact block 5 and the buffer pad 51, the situation where the rack 18 disengages from the semi-arc gear 19 due to equipment malfunction is reduced.

[0037] like Figure 5 As shown, a sealing ring 6 is provided on the outer wall of the connecting shaft 11.

[0038] When the equipment is working, the sealing ring 6 can increase the sealing between the connecting shaft 11 and the housing 1. By setting the sealing ring 6, the probability of air passing through the gap between the housing 1 and the connecting shaft 11 is reduced.

[0039] like Figure 1 and Figure 2 As shown, the fixed frame 17 is made of a rigid material.

[0040] When the equipment is working, the fixed frame 17 plays an important role in limiting its movement. By using the material of the fixed frame 17, the possibility of bending and breaking during long-term operation is reduced, thereby increasing the stability of the equipment during operation.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
