And when the rope body is located in the first limiting groove, the limiting portion is in limiting cooperation with one side of the second plate body, which can prevent the limiting portion from disengaging from the pressing plate, realizing the installation of the swing rope and the pressing plate, without the need to use other tools, reducing the installation difficulty and improving the assembly efficiency.

It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0056] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0057] Refer to the following Figures 1 to 16 to describe the pressing plate 1 and the air supply device 2 proposed according to some embodiments of the present utility model.

[0058] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 8 、 Figure 12 and Figure 14 shown, the pressing plate 1 is for the air supply device 2. The air supply device 2 includes a swinging rope 20 and a swing switching part 22. The swinging rope 20 includes a limiting part 200 and a rope body 202. The limiting part 200 is connected to the rope body 202. The swing switching part 22 includes a switching part 220 and a base 222. The pressing plate 1 includes: a support plate 10 and a first bending part 11. The first bending part 11 includes a first plate body 12 and a second plate body 14.

[0059] Specifically, one side of the support plate 10 abuts against the switching part 220, and the first end 102 of the support plate 10 is used for rotatably connecting with the base 222; the first plate body 12 is connected between the second plate body 14 and the second end 104 of the support plate 10. There is an included angle between the first plate body 12 and the support plate 10, and there is an included angle between the second plate body 14 and the first plate body 12. And the second plate body 14 extends in a direction away from the first end 102 of the first plate body 12. An installation hole 120 is provided on the first plate body 12, and a first limiting groove 140 is provided on the second plate body 14. One end of the first limiting groove 140 communicates with the installation hole 120; wherein, the installation hole 120 is for the limiting part 200 to pass through so that the rope body 202 is clamped in the first limiting groove 140. The first end 102 and the second end 104 are opposite ends of the support plate 10.

[0060] The pressing plate 1 provided by the present utility model is used for a blowing device 2. The blowing device 2 includes a swinging rope 20 and a swinging switching part 22. The swinging rope 20 includes a limiting part 200 and a rope body 202 connected to the limiting part 200. The swinging switching part 22 includes a base 222 and a switching part 220. The pressing plate 1 includes a supporting plate 10 and a first bending part 11. The first bending part 11 includes a first plate body 12 and a second plate body 14. One side of the supporting plate 10 abuts against the switching part 220. The first end 102 of the supporting plate 10 is used for rotatably connecting to the base 222. The second end 104 of the supporting plate 10 is connected to the first plate body 12. The other end of the first plate body 12 is connected to the second plate body 14. And there is an included angle between the first plate body 12 and the second plate body 14, so that the extending directions of the first plate body 12 and the second plate body 14 are different. Wherein, an installation hole 120 is provided on the first plate body 12, and a first limiting groove 140 is provided on the second plate body 14. The installation hole 120 is used for the limiting part 200 to pass through. Since the installation hole 120 is communicated with the first limiting groove 140, the rope body 202 can enter the first limiting groove 140 along with the movement of the limiting part 200, realizing the connection between the swinging rope 20 and the pressing plate 1. When the swinging rope 20 is pulled, the pressing plate 1 can rotate relative to the base 222. Further, the supporting plate 10 can press the switching part 220, so that the switching part 220 switches the working state, realizing the swinging function of the blowing device 2. During the installation of the swinging rope 20 and the pressing plate 1, no other tools are required, reducing the installation difficulty, improving the assembly efficiency, and being able to avoid the problem of deformation of the pressing plate 1, making the pulling force of the swinging rope 20 more uniform. At the same time, the first limiting groove 140 and the installation hole 120 are located on different plate bodies, which can reduce the possibility of the limiting part 200 coming out, improving the reliability of the connection between the swinging rope 20 and the pressing plate 1.

[0061] Optionally, the first plate body 12 extends towards the side where the supporting plate 10 abuts against the switching part 220.

[0062] In a specific application, when installing the swinging rope 20, first pass the limiting part 200 through the installation hole 120 on the first plate body 12, and then move the whole swinging rope 20 towards the second plate body 14, so that the rope body 202 enters the first limiting groove 140, and make the limiting part 200 abut against one side of the second plate body 14, realizing the connection between the swinging rope 20 and the second plate body 14.

[0063] Optionally, the supporting plate 10, the first plate body 12 and the second plate body 14 are integrally formed.

[0064] In some embodiments, optionally, a second limiting groove 122 is further provided on the first plate body 12. The two ends of the second limiting groove 122 are respectively communicated with the first limiting groove 140 and the installation hole 120; or the first limiting groove 140 is communicated with the installation hole 120 at the connection of the first plate body 12 and the second plate body 14.

[0065] In this embodiment, the communication between the first limiting groove 140 and the mounting hole 120 can be a direct communication between the two. For example, both the first limiting groove 140 and the mounting hole 120 are close to the connection between the first plate body 12 and the second plate body 14, so that the first limiting groove 140 and the mounting hole 120 communicate at the connection between the first plate body 12 and the second plate body 14. As Figure 4 、 Figure 9 and Figure 13 shown, the first limiting groove 140 and the mounting hole 120 can also be communicated through the second limiting groove 122. For example, a second limiting groove 122 is added to the first plate body 12, and both ends of the second limiting groove 122 communicate with the first limiting groove 140 and the mounting hole 120 respectively. Thus, the rope body 202 can move from the second limiting groove 122 into the first limiting groove 140 to realize the limiting of the rope body 202.

[0066] As Figure 4 、 Figure 9 and Figure 13 shown, in some embodiments, optionally, when the second limiting groove 122 is provided on the first plate body 12, the second limiting groove 122 is located on the side of the mounting hole 120 close to the second plate body 14.

[0067] In this embodiment, the second limiting groove 122 is located on the side of the mounting hole 120 close to the second plate body 14, so that there is a height difference between the mounting hole 120 and the first limiting groove 140, thereby reducing the possibility of the limiting portion 200 disengaging from the mounting hole 120 and improving the reliability of the connection between the swinging head rope 20 and the pressing plate 1.

[0068] It can be understood that the second limiting groove 122 extends from the side of the mounting hole 120 close to the second plate body 14 towards the second plate body 14, and the first limiting groove 140 extends from the connection with the second limiting groove 122 in a direction away from the second limiting groove 122. In this way, when installing the swinging head rope 20, as Figure 2 、 Figure 4 、 Figure 5 、 Figure 9 and Figure 10 shown, align the limiting portion 200 with the mounting hole 120 from the side of the mounting hole 120 facing away from the second plate body 14, and align the rope body 202 with the connection between the second limiting groove 122 and the mounting hole 120. As Figure 6 、 Figure 7 、 Figure 8 and Figure 11As shown, the limiting part 200 is then moved into the mounting hole 120. During the process that the limiting part 200 passes through the mounting hole 120 and continues to move to the other side of the first plate body 12, the rope body 202 first enters the second limiting groove 122 along with the limiting part 200, and then directly enters the first limiting groove 140 along with the movement of the limiting part 200, without the need to bend the rope body 202 or perform other operations, reducing the installation difficulty.

[0069] It can be understood that the second limiting groove 122 penetrates the first plate body 12 along the thickness direction of the first plate body 12, and the first limiting groove 140 penetrates the second plate body 14 along the thickness direction of the second plate body 14.

[0070] It can be understood that the design of the setting positions of the second limiting groove 122 and the first limiting groove 140 enables the rope body 202 not to be bent when installing the swing head rope 20. Especially when the rope body 202 is rigid and not easy to bend, the processing difficulty is greatly reduced.

[0071] Optionally, the length of the second limiting groove 122 is greater than or equal to the height of the limiting part 200 on the first plate body 12. In this way, even when the swing head rope 20 moves to the connection part of the first plate body 12 and the second plate body 14 during operation, there is a certain height difference between the mounting hole 120 and the limiting part 200, thereby avoiding the limiting part 200 from disengaging from the mounting hole 120.

[0072] Optionally, the axis of the mounting hole 120, the center line of the first limiting groove 140, and the center line of the second limiting groove 122 are located in the same plane.

[0073] As Figure 1 、 Figure 2 and Figure 12 shown, in some embodiments, optionally, the pressing plate 1 further includes: a second bending part 16, the second bending part 16 is arranged at the first end 102 of the support plate 10 and is arranged opposite to the first bending part 11, and the support plate 10 is rotatably connected to the base 222 through the second bending part 16.

[0074] In this embodiment, the pressing plate 1 is rotatably connected to the base 222 through the second bending part 16. When pulling the swing head rope 20, the pressing plate 1 can be rotated, thereby realizing the pressing operation on the switching part 220.

[0075] Optionally, the second bending part 16 extends towards the side where the support plate 10 abuts against the switching part 220.

[0076] As Figure 1 and Figure 2 shown, in some embodiments, optionally, the end of the second bending part 16 away from the support plate 10 is bent and connected to the base 222.

[0077] In this embodiment, the second bending portion 16 is provided at the first end 102 of the support plate 10 and is disposed opposite to the first bending portion 11, and one end of the second bending portion 16 away from the support plate 10 is bent, which improves the connection reliability between the base 222 and the second bending portion 16.

[0078] It can be understood that the second bending portion 16 and the first plate body 12 are disposed opposite to each other at both ends of the support plate 10.

[0079] Such as Figure 6 and Figure 7 As shown, in some embodiments, optionally, the mounting hole 120 includes a round hole, and the first limiting groove 140 includes a strip-shaped groove; wherein, the diameter L2 of the mounting hole 120 is greater than the width L1 of the first limiting groove 140.

[0080] In this embodiment, the mounting hole 120 includes a round hole, the first limiting groove 140 includes a strip-shaped groove, and the diameter L2 of the mounting hole 120 is greater than the width L1 of the first limiting groove 140, so that the limiting portion 200 can pass through the mounting hole 120 but cannot pass through the first limiting groove 140. Furthermore, the mounting of the limiting portion 200 is realized through the mounting hole 120, and the limiting of the rope body 202 and the limiting of the limiting portion 200 are realized through the first limiting groove 140, avoiding the situation that the shaking head rope 20 is separated from the plate body.

[0081] It can be understood that the diameter of the limiting portion 200 is smaller than the width of the first limiting groove 140.

[0082] In some embodiments, optionally, the included angle between the first plate body 12 and the second plate body 14 is greater than or equal to 70° and less than or equal to 110°; and / or the included angle between the first plate body 12 and the support plate 10 is greater than or equal to 70° and less than or equal to 110°.

[0083] In this embodiment, the included angle between the first plate body 12 and the second plate body 14 is greater than or equal to 70° and less than or equal to 110°; and / or the included angle between the first plate body 12 and the support plate 10 is greater than or equal to 70° and less than or equal to 110°, so that the first plate body 12 is bent with respect to the support plate 10, and the second plate body 14 is bent with respect to the first plate body 12.

[0084] Optionally, the first plate body 12 and the second plate body 14 are perpendicular to each other. The first plate body 12 is perpendicular to the support plate 10.

[0085] Such as Figure 14 、 Figure 15 and Figure 16As shown, according to an embodiment of the present invention, a blowing device 2 is further provided, including: a shaking rope 20, the shaking rope 20 includes a limiting portion 200 and a rope body 202, the limiting portion 200 is connected to the rope body 202; a shaking switching portion 22, the shaking switching portion 22 includes a switching portion 220 and a base 222; and a pressing plate 1 as proposed in any of the above.

[0086] The blowing device 2 provided by the present invention includes the pressing plate 1 proposed in any of the above embodiments, so it has all the beneficial effects of the pressing plate 1.

[0087] Wherein, one side of the support plate 10 abuts against the switching portion 220, the first end 102 of the support plate 10 is used for rotatably connecting with the base 222, a mounting hole 120 is provided on the first plate body 12, and a first limiting groove 140 is provided on the second plate body 14. The mounting hole 120 is used for the limiting portion 200 to pass through. Since the mounting hole 120 is communicated with the first limiting groove 140, the rope body 202 can enter the first limiting groove 140 along with the movement of the limiting portion 200, realizing the connection between the shaking rope 20 and the pressing plate 1.

[0088] As Figure 7 and Figure 8 As shown, in some embodiments, optionally, the limiting portion 200 is in a cylindrical shape, and the rope body 202 is connected to the side wall of the limiting portion 200; when the mounting hole 120 is a round hole and the shaking rope 20 is mounted on the pressing plate 1, the included angle between the axis of the limiting portion 200 and the axis of the mounting hole 120 is greater than 0° and less than 180°.

[0089] In this embodiment, the limiting portion 200 is in a cylindrical shape, the rope body 202 is connected to the side wall of the limiting portion 200. When the shaking rope 20 is mounted on the pressing plate 1, the axis C of the limiting portion 200 is not parallel to the axis D of the mounting hole 120, thereby reducing the possibility of the limiting portion 200 directly disengaging from the mounting hole 120.

[0090] In specific applications, when installing the shaking rope 20, align the axis C of the limiting portion 200 with the axis D of the mounting hole 120, so that the limiting portion 200 passes through the mounting hole 120. After the limiting portion 200 passes through the mounting hole 120, move the limiting portion 200 so that the rope body 202 enters the first limiting groove 140. When the limiting portion 200 moves to the second plate body 14, rotate the limiting portion 200 so that the axis C of the limiting portion 200 is not parallel to the axis D of the mounting hole 120. Optionally, make the axis C of the limiting portion 200 perpendicular to the axis D of the mounting hole 120 to improve the connection reliability between the shaking rope 20 and the pressing plate 1.

[0091] Optionally, the limiting portion 200 is provided at one end of the rope body 202.

[0092] Optionally, the rope body 202 is a rigid rope body.

[0093] In some embodiments, optionally, when the swing rope 20 is connected to the pressing plate 1, the limiting portion 200 abuts against one side of the second plate body 14 in the thickness direction, the rope body 202 is clamped in the first limiting groove 140, and extends from the limiting portion 200 to the other side of the second plate body 14 in the thickness direction.

[0094] In this embodiment, when installing the swing rope 20, the limiting portion 200 of the swing rope 20 is passed through the mounting hole 120 from one side of the first plate body 12 to the other side of the first plate body 12. Since one end of the first limiting groove 140 is communicated with the mounting hole 120, the rope body 202 of the swing rope 20 can be moved into the first limiting groove 140 along with the limiting portion 200. And when the rope body 202 is located in the first limiting groove 140, the limiting portion 200 is in limit cooperation with one side of the second plate body 14, which can prevent the limiting portion 200 from detaching from the pressing plate 1, realizing the installation of the swing rope 20 and the pressing plate 1, without the need to use other tools, reducing the installation difficulty and improving the assembly efficiency.

[0095] As Figure 14 、 Figure 15 and Figure 16 shown, in some embodiments, optionally, the air supply device 2 further includes: a bracket 24, and the swing switching portion 22 is disposed on the bracket 24; a fan head 26, which is movably connected to the bracket 24, the swing switching portion 22 is connected to the fan head 26, and the swing rope 20 switches the working state of the swing switching portion 22 through the pressing plate 1, so that the fan head 26 switches between a swing state and a stationary state.

[0096] In this embodiment, the air supply device 2 further includes a bracket 24 and a fan head 26. The fan head 26 is movably connected to the bracket 24, so that the fan head 26 can rotate relative to the bracket 24 to realize the swing function of the air supply device 2. Among them, the swing switching portion 22 is connected to the fan head 26. When pulling the swing rope 20, the swing rope 20 drives the swing switching portion 22 to switch the working state through the pressing plate 1, so that the fan head 26 switches to the swing state or the stationary state.

[0097] In some embodiments, optionally, the air supply device 2 further includes: a pull rope 28, and the pull rope 28 is connected to the rope body 202 through a pulley structure.

[0098] In this embodiment, the air supply device 2 further includes a pull rope 28. The pull rope 28 is connected to the rope body 202 through a pulley structure. By pulling the pull rope 28, the transmission of power is realized through the pulley structure, and then the pressing plate 1 drives the swing switching portion 22 to switch the working state.

[0099] In a specific application, the other end of the swinging steel rope (such as the swinging rope 20) is fixed on the base 222. The swinging pulling rope (such as the pulling rope 28) controls whether the fan swings through a movable pulley and a pulling pulley. The pulling pulley and the movable pulley are connected to the swinging steel rope. The swinging steel rope pulls the pressing plate 1 downward, and the pressing plate 1 presses the shaft of the swinging gearbox (such as the switching part 220) to achieve the control of the fan's swinging.

[0100] Optionally, a round hole with a diameter of 5 mm (such as the mounting hole 120) and a limiting groove with a width of 2 mm (such as the first limiting groove 140 and the second limiting groove 122, the diameter of the round hole and the width of the limiting groove are not limited to this) are added to the pressing plate 1. The swinging steel rope passes through the round hole and slides in through the limiting groove to achieve the connection between the swinging steel rope and the pressing plate 1.

[0101] One end of the pressing plate 1 is fixed to the gearbox cover of the gearbox (such as the base 222), and the other end is connected to the swinging steel rope. The pressing of the gearbox is controlled to swing or not swing through the lever principle.

[0102] The function of the steel rope is to achieve the transmission of force. One end of the steel rope is connected to the pressing plate 1, and the other end is connected to the swinging pulling rope that controls the swing. When the user pulls the swinging pulling rope, the function of controlling the swing and non-swing of the fan head 26 can be achieved.

[0103] The present application provides a connection method between the swinging steel rope and the pressing plate 1, which includes parts such as the swinging steel rope and the pressing plate 1. Without using pliers to straighten the bent part of the pressing plate 1, the head of the swinging steel rope (such as the limiting part 200) passes through the round hole and slides in through the limiting groove to achieve the connection between the swinging steel rope and the pressing plate 1; the connection method between the swinging steel rope and the pressing plate 1 is simplified, the problem that the pressing plate 1 is deformed by pliers is solved, and the pulling force of the swinging pulling rope is made more uniform. The total assembly production efficiency is increased by 20%.

[0104] Optionally, the air supply device 2 includes a wall fan.
