Description

Technical Field

[0001] The invention relates to the technical field of fan accessories, in particular to an elastic support seat of an energy-saving fan. Background Art

[0002] The fan support base is a vital component in the fan system, which mainly plays the role of bearing, stabilizing and supporting the fan equipment. The fan support base is a component that connects the fan to the ground or other fixed structures. It is used to bear the weight of the fan and ensure the stability and safety of the fan during operation. The fan support base is usually made of high-strength, corrosion-resistant materials such as cast iron, steel, aluminum alloy or special alloys. These materials not only have sufficient bearing capacity, but also maintain stable performance in harsh environments. In addition, in order to enhance the stability and durability of the support base, manufacturers will also adopt advanced manufacturing processes and processing technologies, such as heat treatment and surface treatment. The support base can bear the entire weight of the fan equipment, including the fan body, motor, transmission device, etc.

[0003] After searching, the patent document (authorization announcement number is CN108443234B) includes a base and a seat body made of rubber material arranged on the base, and the bottom surface of the seat body is concave to form a deformation cavity; a frame is provided in the base body, and the frame is a spiral spring that stretches in the up and down directions, and the deformation cavity is located inside the space surrounded by the frame; a damping device is provided in the deformation cavity, and the damping device includes a magnetorheological torsional vibration damper and a motion conversion mechanism for converting the linear motion generated by the vibration into a rotational motion so that the magnetorheological torsional vibration damper can suppress the vibration; the motion conversion mechanism includes a rack for bearing the vibration load and a gear for converting the linear motion of the rack into a rotational motion, the upper end of the rack is vertically fixed on the top surface of the deformation cavity, and the lower end cooperates with the guide seat arranged on the base, and the gear is fixedly connected to the rotating shaft of the magnetorheological torsional vibration damper and rotates synchronously; the present invention can reduce the vibration generated by the fan on the equipment on which the fan is installed.

[0004] However, the above device still has shortcomings:

[0005] When placing the support base, the ground cannot be kept level, which causes the fan to tilt as a whole. This not only affects the normal operation efficiency of the fan, but also poses a serious threat to the structural safety of the fan. As the degree of tilt increases, the center of gravity of the fan will deviate from its designed balance point, causing the support structure to bear uneven load distribution. This unbalanced stress state will accelerate fatigue damage to the support material and shorten its service life. Summary of the invention

[0010] Preferably, the side wall of the auxiliary sub-plate is provided with a plurality of limit assemblies, and the plurality of limit assemblies include a plurality of first limit blocks, the first limit blocks are respectively clamped in the first slot and the second slot, the first limit block is fixedly connected to the side wall of the auxiliary sub-plate, the first limit block is fixedly connected to a connecting rod on a side away from the auxiliary sub-plate, the connecting rod is slidably connected to the second limit plate at one end away from the first limit block, a nut fine-tuning assembly is threadedly connected to the end of the first limit block away from the auxiliary sub-plate, a threaded rod is fixedly connected to the end of the first limit block away from the auxiliary sub-plate, the end of the threaded rod away from the first limit block is slidably connected to the second limit plate, and passes through the second limit plate to extend to the side of the second limit plate away from the first limit block, and the threaded rod is arranged on the second limit plate. The end of the limit plate away from the first limit block is threadedly connected to a nut.

[0011] Preferably, the threaded rod is provided on an end of the second limiting plate away from the first limiting block and is sleeved with a gasket, and the gasket is provided between the gasket and the second limiting plate.

[0012] Preferably, an inner core is arranged above the main tooling plate, and core blocks are fixedly connected to both ends of the inner core, and the core blocks are arranged between the nut fine-tuning assembly and the second limiting plate.

[0013] Preferably, a nut height limiting assembly is provided on the top of the main tooling plate, and the nut height limiting assembly is provided at the bottom of the inner core. A secondary tooling plate is provided above the inner core, and both ends of the main tooling plate are fixedly connected to the vertical plate.

[0014] Preferably, the top of the main tooling plate is fixedly connected to a column plate, the top of the column plate is fixedly connected to a column, the outer side of the column is clamped with a clamping plate, both ends of the clamping plate are threadedly connected with fixing screws, and the fixing screws pass through the clamping plate and the protrusion.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. Through the setting of the balancing assembly, it can be achieved that when placing the operation, the overall center of gravity of the base substrate is pressed on the central axis point. Since the central axis point is at the center of the balancing assembly, the use of the balancing assembly will maintain a horizontal state, and the main balancing rod and the auxiliary balancing rod will be tilted under the action of the central axis point and the axis point, thereby adapting to the inclined ground.

[0019] The advantage of this design is that when the center of gravity of the base plate is pressed on the central axis, the main balance rod and the auxiliary balance rod can automatically tilt under the action of the central axis and the axis to adapt to the uneven ground. This design greatly enhances the adaptability and stability of the base plate. Through the automatic adjustment of the balance component, the fan can be kept relatively horizontal even if the ground is tilted. It avoids the possibility that the tilt may cause uneven force on the mechanical parts inside the fan, affecting the service life and safety.

[0020] 2. Through the setting of the limit assembly, when the inner core is fixed, the position of the second limit plate can be changed by turning the nut. Secondly, the nut fine-tuning assembly includes a screw and a nut. By turning the nut, its position on the screw can be adjusted, so that the screw and the second limit plate are against the core block to achieve the effect of fixed limitation. Since the nut is rotatable, the limit assembly can be applied to more scenarios, expanding its scope of use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figure 1-9As shown, an elastic support seat of an energy-saving fan includes a base substrate 1, a main tooling plate 101 is arranged on the top of the base substrate 1, the top of the main tooling plate 101 is threadedly connected with a first fixing screw 102, the first fixing screw 102 passes through the main tooling plate 101 and the base substrate 1, a pair of vertical plates 2 are fixedly connected to the top of the main tooling plate 101, a protrusion 201 is engraved on the side wall of the vertical plate 2, the protrusion 201 and the vertical plate 2 form an area as a first slot 21, and a second slot 22 is opened on the side wall of the vertical plate 2, and a pair of auxiliary sub-plates 210 are fixedly connected to the top of the main tooling plate 101, and the angle between the pair of auxiliary sub-plates 210 and the vertical plate 2 is ninety degrees.

[0034] The threaded rod 34 is disposed on one end of the second limiting plate 33 away from the first limiting block 31 and is sleeved with a gasket 36 . The gasket 36 is disposed between the gasket 36 and the second limiting plate 33 .

[0035] An inner core 4 is disposed above the main tooling plate 101 , and core blocks 41 are fixedly connected to both ends of the inner core 4 . The core blocks 41 are disposed between the nut fine-tuning assembly 37 and the second limiting plate 33 .

[0036] A nut height limiting assembly 42 is provided on the top of the main tooling plate 101, and the nut height limiting assembly 42 is provided at the bottom of the inner core 4. An auxiliary tooling plate 103 is provided above the inner core 4. Both ends of the main tooling plate 101 are fixedly connected to the vertical plate 2. When the inner core 4 is fixed, the position of the second limiting plate 33 can be changed by screwing the nut 35. Secondly, the nut fine-tuning assembly 37 includes a screw and a nut. By screwing the nut, its position on the screw can be adjusted, so that the screw and the second limiting plate 33 are against the core block 41 to achieve the effect of fixed limiting. Since the nut is rotatable, the limiting assembly 3 can be applied to more scenarios, expanding its scope of use.

[0040] A balancing component 6 is provided at the bottom of the base substrate 1, and the balancing component 6 includes a groove 61, and the groove 61 is opened at the bottom of the base substrate 1. The side wall of the groove 61 is fixedly connected with a central axis point 62, and the bottom of the central axis point 62 is rotatably connected with a main balancing rod 63, and both ends of the main balancing rod 63 are rotatably connected with an axis point 64, and the outer side of the axis point 64 is rotatably connected with a secondary balancing rod 65, and both ends of the bottom of the secondary balancing rod 65 are rotatably connected with support rods 66.

[0041] When placing the base substrate 1, the center of gravity of the base substrate 1 is pressed on the center axis point 62. Since the center axis point 62 is located at the center of the balancing component 6, the balancing component 6 will remain horizontal when used, and the main balancing rod 63 and the auxiliary balancing rod 65 will be tilted under the action of the center axis point 62 and the axis point 64 to adapt to the inclined ground.

[0042] When the center of gravity of the base substrate 1 is pressed on the central axis 62, the main balance rod 63 and the auxiliary balance rod 65 can automatically tilt under the action of the central axis 62 and the axis 64 to adapt to the uneven ground. This design greatly enhances the adaptability and stability of the base substrate 1. Through the automatic adjustment of the balance component 6, even if the ground is tilted, it can ensure that the fan as a whole remains in a relatively horizontal state.

[0044] Working principle: When placing the base substrate 1, the center of gravity of the base substrate 1 is pressed on the center axis point 62. Since the center axis point 62 is located at the center of the balancing component 6, the balancing component 6 will remain horizontal when used, and the main balancing rod 63 and the auxiliary balancing rod 65 will be tilted under the action of the center axis point 62 and the axis point 64, thereby adapting to the inclined ground.

[0045] When the inner core 4 needs to be adjusted, the position of the second limit plate 33 can be changed by turning the nut 35. Secondly, the nut fine-tuning assembly 37 includes a screw and a nut. By turning the nut, its position on the screw can be adjusted, so that the screw and the second limit plate 33 are against the core block 41 to achieve a fixed limit effect. Since the nut is rotatable, the limit assembly 3 can be applied to more scenarios, expanding its scope of use.

[0046] The above embodiments are only used to illustrate the technical method of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical method of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical method of the present invention.
