Description

[Technical Field]

[0001] This utility model relates to the field of suspension device technology, specifically to a suspension system and a hanging fan. [Background Technology]

[0002] Currently, most hanging systems on the market, such as ceiling fans, light fixture brackets, and monitoring equipment, use bolts for direct fixing. Adjusting the angle usually requires disassembly and reassembly, a cumbersome process that makes precise positioning difficult. For example, patent application number "202020237405.8" discloses a wall-mounted electric fan with two connecting joints for horizontal and vertical adjustment, both fixed by tightening the rotating shaft. However, during prolonged use, the fan's vibrations can easily cause the joints to loosen, especially at the rotating shaft. Particularly at the vertical angle, the fan's own weight can cause it to rotate downwards along the shaft. Furthermore, precisely because of this risk of loosening, the connecting joints are not designed to be too long; otherwise, an excessively long lever arm could lead to excessive stress on the joint, further increasing the likelihood of instability. This limits the fan's adjustment range and makes it difficult to meet the diverse needs of users in different scenarios.

[0003] In view of the above-mentioned technical problems, this utility model is proposed in this study. [Utility Model Content]

[0004] The technical problem to be solved by this utility model is to provide a suspension system and a hanging fan. By setting a horizontal elastic positioning component between the first connecting rod and the connecting seat, and setting an elevation elastic positioning component between the second connecting rod and the fan, the connection joint of the fan can be effectively prevented from loosening and falling off during use after the position is adjusted, thereby improving the stability and reliability of the suspension system, while expanding the adjustment range to meet the user's needs in different scenarios.

[0005] To solve the above-mentioned technical problems, this utility model proposes a suspension system, comprising:

[0006] Connector, used for mounting on load-bearing surfaces;

[0007] The first connecting rod has a horizontal adjustment connecting mechanism between its head end and the connecting seat for adjusting the horizontal rotation of the first connecting rod around the connecting seat.

[0008] The second connecting rod has a U-shaped structure, with its middle part connected to the tail end of the first connecting rod, and the open end of the U-shaped structure connected to the functional components through an elevation adjustment mechanism.

[0009] The horizontal adjustment connection mechanism includes:

[0010] An upper connecting part and a lower connecting part are provided on the connecting seat at intervals;

[0011] A rotating part is provided between the upper connecting part and the lower connecting part, and one side of the rotating part is connected to the head end of the first connecting rod;

[0012] A rotating rod passes through the upper connecting part, the rotating part, and the lower connecting part. The first connecting rod rotates horizontally around the axis of the rotating rod via the rotating part.

[0013] The upper and lower adjustment knobs, respectively located at both ends of the rotating rod, generate an axial clamping force between the upper and lower connecting parts by tightening the upper and lower adjustment knobs to clamp the rotating part.

[0014] The horizontal elastic positioning components, respectively located at the upper and lower ends of the rotating part, include horizontal movable holes at the upper and lower ends of the rotating part and horizontal springs elastically disposed in the horizontal movable holes. Both the upper and lower connecting parts are provided with a plurality of horizontal locking positions arranged in a ring around the axis of the rotating rod.

[0015] When the upper or lower adjustment knob is in the loose state, the first connecting rod can be rotated, and the horizontal spring will selectively engage with the horizontal locking position under the action of elastic force, thereby adjusting the angle of horizontal rotation of the first connecting rod around the axis of the rotating rod.

[0016] When the upper or lower adjustment knob is in the locked state, the rotation of the rotating part is restricted between the upper and lower connecting parts under the axial clamping force;

[0017] The elevation adjustment connection mechanism includes a left connection component and a right connection component located at both ends of the U-shaped opening. The left connection component and the right connection component have the same structure. The left connection component includes:

[0018] The left connecting ear is located on the left end of the U-shaped opening;

[0019] Functional connection part, which connects to functional components;

[0020] The tilt adjustment knob is used to connect the left connecting lug to the functional connecting part and to lock the left connecting lug to the functional connecting part;

[0021] The swing angle elastic positioning component includes an elevation angle movable hole provided on the functional connection part and an elevation angle spring bead elastically provided in the elevation angle movable hole. Several elevation angle locking positions are formed on the left connecting ear and distributed in a ring around the axis of the elevation angle adjustment knob.

[0022] When the elevation adjustment knob is in the loose state, the rotating functional component can be rotated, and the elevation spring can selectively engage with the elevation locking position under the action of elastic force, thereby adjusting the elevation angle of the functional component.

[0023] When the tilt adjustment knob is locked, the function component is restricted from rotating in the U-shaped opening.

[0024] In the suspension system described above, a swing angle adjustment mechanism is provided between the first connecting rod and the second connecting rod for adjusting the left and right swing of the second connecting rod relative to the first connecting rod. The swing angle adjustment mechanism includes:

[0025] The first swing angle connecting part is located at the tail end of the first connecting rod;

[0026] The second swing angle connecting part is located in the middle of the second connecting rod;

[0027] The swing angle adjustment knob is used to connect the first swing angle connecting part and the second swing angle connecting part, and can lock the first swing angle connecting part and the second swing angle connecting part;

[0028] The swing angle elastic positioning component includes a swing angle movable hole provided on the first swing angle connecting part and a swing angle spring bead elastically provided in the swing angle movable hole. The second swing angle connecting part is formed with a plurality of swing angle locking positions arranged in a ring around the axis of the swing angle adjustment knob.

[0029] When the swing angle adjustment knob is in the loose state, the second connecting rod can be rotated, and the swing angle spring can selectively engage with the swing angle locking position under the action of elastic force, thereby adjusting the swing angle of the second connecting rod and thus the swing angle of the functional component.

[0030] When the swing angle adjustment knob is in the locked state, it restricts the rotation of the second swing angle connecting part relative to the first swing angle connecting part, thereby restricting the functional component from swinging left and right through the second connecting rod.

[0031] In the suspension system described above, the upper adjustment knob and the lower adjustment knob are threadedly connected to the rotating rod.

[0032] As described above, in a suspension system, the functional connection part has a mounting cavity formed thereon, the opening of the mounting cavity is provided with a cavity cover, the elevation angle movable hole is provided on the cavity cover, and the mounting cavity is provided with an elastic element that is elastically connected to the elevation angle spring.

[0033] In the suspension system described above, the elastic element is a V-shaped spring, one end of which is connected to the lower end of the elevation spring, and the other end is connected to the bottom of the mounting cavity.

[0034] In the suspension system described above, the elastic element is a U-shaped spring, one end of which is connected to the lower end of the elevation spring, and the other end is connected to the bottom of the mounting cavity.

[0035] As described above, in a suspension system, the elastic element includes a movable rod that slides with the bottom of the mounting cavity and a spring sleeved on the movable rod, with the top of the movable rod connected to an elevation spring.

[0036] This application also provides a hanging fan, the functional component of which is a fan body, and it also includes the suspension system described above, wherein the fan body is connected to the left connecting component and the right connecting component in the tilt adjustment mechanism.

[0037] As described above, a wall-mounted fan has a light source on the air outlet surface of the fan body.

[0038] Compared with the prior art, this utility model has the following advantages:

[0039] 1. This application provides pre-positioning during the adjustment process by setting up a horizontal elastic positioning component and an elevation elastic positioning component, and achieves final locking through axial clamping force to prevent loosening after long-term use.

[0040] 2. By setting up a horizontal elastic positioning component and an elevation elastic positioning component, this application allows the first connecting rod and the second connecting rod to be longer, and to have a larger adjustment range.

[0041] 3. This application also provides a swing angle adjustment connection mechanism between the first connecting rod and the second connecting rod. The swing angle adjustment connection mechanism also has a swing angle elastic positioning component to realize multi-dimensional precise adjustment of the fan in horizontal rotation, pitch angle and left and right swing angle direction.

[0042] 4. The horizontal, vertical, and swing angle elastic positioning components of this application all adopt the same elastic positioning principle, which can reduce production costs and facilitate maintenance. [Attached Image Description]

Detailed Implementation Methods

[0062] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0063] like Figure 1-13As shown, this utility model includes a suspension system, comprising a connecting seat 1, a first connecting rod 10, and a second connecting rod 11. The connecting seat 1 is used to install on a load-bearing surface to install the entire suspension system at a desired location, such as a wall or shelf. A horizontal adjustment connecting mechanism 2 is provided between the head end of the first connecting rod 10 and the connecting seat 1 for adjusting the horizontal rotation of the first connecting rod 10 around the connecting seat 1. The second connecting rod 11 has a U-shaped structure, with its middle part connected to the tail end of the first connecting rod 10. The U-shaped open end is connected to a functional component through an elevation adjustment connecting mechanism 3. The functional component can be a fan, a lighting lamp, or a monitoring device. In this application, a fan is used as an example below.

[0064] like Figure 3 , Figure 4 , Figure 5 as well as Figure 12 As shown, the horizontal adjustment connecting mechanism 2 includes an upper connecting part 20, a lower connecting part 21, a rotating part 22, a rotating rod 23, an upper adjusting knob 24, a lower adjusting knob 25, and a horizontal elastic positioning assembly 200. The upper connecting part 20 and the lower connecting part 21 are vertically spaced on the connecting seat 1. The rotating part 22 is located between the upper connecting part 20 and the lower connecting part 21, and one side of the rotating part 22 is connected to the first end of the first connecting rod 10. The rotating rod 23 passes through the upper connecting part 20, the rotating part 22, and the lower connecting part 21. The first connecting rod 10 rotates horizontally around the axis of the rotating rod 23 via the rotating part 22. The upper adjusting knob 24 and the lower adjusting knob 25 are respectively located at both ends of the rotating rod 23. The upper connecting part 20 and the lower connecting part 21 are pressed together by tightening the lower adjusting knob 25 to generate an axial pressing force between them, thereby pressing the rotating part 22. Two horizontal elastic positioning components 200 are provided, which are respectively provided at the upper and lower ends of the rotating part 22. The horizontal elastic positioning components 200 include horizontal movable holes 201 provided at the upper and lower ends of the rotating part 22 and horizontal springs 202 elastically provided in the horizontal movable holes 201. Both the upper connecting part 20 and the lower connecting part 21 are provided with a plurality of horizontal locking positions 203 arranged in a ring around the axis of the rotating rod 23.

[0065] When the upper adjustment knob 24 or the lower adjustment knob 25 is in the disengaged state, the first connecting rod 10 can be rotated. The horizontal spring 202 then selectively engages with the horizontal locking position 203 under the action of elastic force, thereby adjusting the angle of horizontal rotation of the first connecting rod 10 around the axis of the rotating rod 23. It should be noted that since both the upper adjustment knob 24 and the lower adjustment knob 25 are connected to the rotating rod 23, the restriction on the rotating part 22 can be released simply by disengaging either the upper adjustment knob 24 or the lower adjustment knob 25. When the upper adjustment knob 24 or the lower adjustment knob 25 is in the locked state, the axial clamping force restricts the rotation of the rotating part 22 between the upper connecting part 20 and the lower connecting part 21. Since the horizontal elastic positioning component 200 is provided, when the upper adjustment knob 24 or the lower adjustment knob 25 is in the locked state, the horizontal spring 202 of the horizontal elastic positioning component 200 will be locked into the corresponding locking position, which can further prevent the rotating part 22 from rotating, thereby preventing the fan from becoming loose between the first connecting rod 10 and the connecting seat 1 during long-term use.

[0066] like Figure 3 , Figure 4 , Figure 6 as well as Figures 9 to 11 As shown, the elevation angle adjustment connection mechanism 3 includes a left connecting component 30 and a right connecting component 31 respectively disposed at both ends of the U-shaped opening. The left connecting component 30 and the right connecting component 31 have the same structure. The left connecting component 30 includes a left connecting ear 32, a functional connecting part 33, an elevation angle adjustment knob 34, and an elevation angle elastic positioning component 300. The left connecting ear 32 is disposed on the left end of the U-shaped opening. The functional connecting part 33 is connected to the functional component. The elevation angle adjustment knob 34 is used to connect the left connecting ear 32 and the functional connecting part 33 and lock the left connecting ear 32 and the functional connecting part 33. The elevation angle elastic positioning component 300 includes an elevation angle movable hole 301 disposed on the functional connecting part 33 and an elevation angle spring 302 elastically disposed in the elevation angle movable hole 301. The left connecting ear 32 is formed with a plurality of elevation angle locking positions 303 arranged in a ring around the axis of the elevation angle adjustment knob 34.

[0067] When the elevation adjustment knob 34 is in the loose state, the rotatable functional component can be rotated, and the elevation spring 302 can be selectively engaged with the elevation locking position 303 under the action of elastic force, thereby adjusting the elevation angle of the functional component; when the upper elevation adjustment knob 34 is in the locked state, the rotation of the functional component in the U-shaped opening is restricted.

[0068] It should also be noted that the right connecting component 31 has the same structure as the left connecting component 30. Therefore, the connection method of the right connecting component 31 will not be described again in this application.

[0069] In this application, the tilt angle and horizontal position of the fan can be adjusted for user convenience. When adjusting the horizontal position of the fan, the rotating part 22 can be rotated by adjusting the upper adjustment knob 24 or the lower adjustment knob 25. During the rotation, the horizontal spring 202 will be retracted into the horizontal movable hole 201 under force. When rotated to the preset position, the horizontal spring 202 will be locked into the corresponding horizontal locking position 203 under the action of elastic force. Then, it can be locked by adjusting the upper adjustment knob 24 or the lower adjustment knob 25 to complete the adjustment.

[0070] Similarly, the same method is used to adjust the elevation angle, which will not be elaborated here. By setting the horizontal elastic positioning component 200 and the elevation elastic positioning component 300, it is possible to prevent the first connecting rod 10 from becoming loose from the connecting seat 1, and it is also possible to prevent the second connecting rod 11 from becoming loose from the fan.

[0071] like Figure 3 , Figure 4 , Figure 6 as well as Figure 7 As shown, as a further embodiment, a swing angle adjustment connecting mechanism 4 is provided between the first connecting rod 10 and the second connecting rod 11 for adjusting the left and right swing of the second connecting rod 11 relative to the first connecting rod 10. The swing angle adjustment connecting mechanism 4 includes a first swing angle connecting part 40, a second swing angle connecting part 41, a swing angle adjustment knob 42, and a swing angle elastic positioning component 400. The first swing angle connecting part 40 is located at the tail end of the first connecting rod 10, and the second swing angle connecting part 41 is located in the middle of the second connecting rod 11. The swing angle adjustment knob 42 is used to connect the first swing angle connecting part 40 and the second swing angle connecting part 41, and can lock the first swing angle connecting part 40 and the second swing angle connecting part 41. The swing angle elastic positioning component 400 includes a swing angle movable hole 401 provided on the first swing angle connecting part 40 and a swing angle spring 402 elastically provided in the swing angle movable hole 401. The second swing angle connecting part 41 is formed with a plurality of swing angle locking positions 403 arranged in a ring around the axis of the swing angle adjustment knob 42.

[0072] When the swing angle adjustment knob 42 is in the loose state, the second connecting rod 11 can be rotated, and the swing angle spring 402 selectively engages with the swing angle locking position 403 under the action of elastic force, thereby adjusting the swing angle of the second connecting rod 11, and thus adjusting the swing angle of the functional component.

[0073] When the swing angle adjustment knob 42 is in the locked state, it restricts the rotation of the second swing angle connection part 41 relative to the first swing angle connection part 40, thereby restricting the functional component from swinging left and right through the second connecting rod 11.

[0074] In this embodiment, the first connecting rod 10 and the second connecting rod 11 are connected by a swing angle adjustment connecting assembly, allowing the second connecting rod 11 to be adjusted left and right around the first connecting rod 10, thereby adjusting the airflow direction of the fan for user convenience. It should also be noted that the operation of the swing angle adjustment connecting mechanism 4 is the same as that of the elevation angle adjustment connecting mechanism 3, and therefore will not be described again in this application.

[0075] As a further embodiment, the upper adjustment knob 24 and the lower adjustment knob 25 are threadedly connected to the rotating rod 23. This threaded connection facilitates user adjustment. It should also be noted that the locking method for the swing angle adjustment knob 42 and the elevation angle adjustment knob 34 is a conventional technique in the art, and therefore will not be described further in this application.

[0076] like Figures 9 to 11 As shown, as a further embodiment, the functional connecting part 33 has a mounting cavity 304 formed on it. A cavity cover 305 is provided at the opening of the mounting cavity 304, and an elevation angle movable hole 301 is provided on the cavity cover 305. An elastic element 306, which is elastically connected to the elevation angle spring 302, is provided in the mounting cavity 304. In this embodiment, after the elastic element 306 is installed, the cavity cover 305 can be fixed to the opening of the mounting cavity 304 by welding, which can increase the connection strength and prevent loosening and detachment during later use.

[0077] Check Figure 10 The elastic element 306 is a V-shaped spring sheet, one end of which is connected to the lower end of the elevation spring bead 302, and the other end is connected to the bottom of the mounting cavity 304.

[0078] Check Figure 9 The elastic element 306 can also be a U-shaped spring, with one end connected to the lower end of the elevation spring 302 and the other end connected to the bottom of the mounting cavity 304.

[0079] Check Figure 11 In addition, the elastic element 306 can also be composed of a spring 307 and a movable rod 308. The movable rod 308 is slidably engaged with the bottom of the mounting cavity 304, the spring 307 is sleeved on the movable rod 308, and the top of the movable rod 308 is connected to the elevation spring 302. The elevation spring 302 protrudes out of the elevation movable hole 301 under the action of the spring 307.

[0080] It should be noted that the horizontal spring 202 and the sway spring 402 can also be installed in the same way, and the same elastic element 306 can be used to connect with the corresponding sway spring 402 and horizontal spring 202. This will not be elaborated further here.

[0081] like Figure 1 , Figure 2As shown, this application also provides a wall-mounted fan, wherein the functional component is a fan body 5, and it also includes a suspension system using the present application. The fan body 5 is connected to the left connecting component 30 and the right connecting component 31 in the tilt adjustment connecting mechanism 3. In addition, a light 6 is provided on the air outlet surface of the fan body 5. This wall-mounted fan is installed using the suspension system of the present application, which facilitates adjustment and provides a more secure connection, preventing the connecting joints from loosening during use.
