Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to a motor support structure that can be flexibly adjusted. Background Technology

[0002] Axial flow fans have a wide range of applications and are used in large quantities. They are typically installed in civil buildings, industrial and mining plants, and various venues for ventilation and fire smoke extraction. There are many series of axial flow fans, and many power models within the same series. In actual engineering applications, fans of the same model number (same diameter) are often equipped with different power ratings to meet different performance parameter requirements. This leads to various problems during the manufacturing process. The model and size of the motor fixing support structure will vary. The same model number of fan often needs to be configured with at least 3-5 power ratings, which means that the same motor support structure will have 3-5 different model and size ratings. This is very troublesome in processing and manufacturing. The size of the motor support structure and the size of the connecting holes must correspond one-to-one with the size of the motor. In the material cutting and welding processes, each specification must be made accordingly. This results in poor versatility, which is easy to get confused, leading to motor installation problems and wasting material and labor costs. Utility Model Content

[0003] In view of the shortcomings of the existing technology, this utility model provides a motor support structure that can be flexibly adjusted, thus solving the problem of poor adaptability of the support structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a flexibly adjustable motor support structure, including a mounting frame, two sets of fixed frames welded inside the mounting frame, a support plate slidably connected between the two sets of fixed frames, four sets of fixing holes opened inside the support plate, a rotary motor fastened to the top of the support plate by locking bolts and fixing holes, and a fan blade connected to the output end of the rotary motor by a key. The fixed frames have three sets of positioning holes inside. Two sets of movable plates are fastened to the bottom of the support plate. The movable plates are fastened to the fixed frames by positioning bolts and positioning holes. Two sets of springs are fastened to opposite sides of the two sets of fixed frames. The end of each spring away from the fixed frame is fastened to a top block, and an anti-slip pad is fastened to the left side of the top block. A bearing is fastened to the right side of the fixed frame. A threaded tube is fastened to the middle of the bearing. A handle is fastened to the right end of the threaded tube. A sleeve is screwed onto the outer side of the threaded tube. Push plates are fastened to both the front and rear sides of the sleeve.

[0005] Preferably, the fixing hole is a rectangular hole, and the three sets of positioning holes are arranged sequentially from top to bottom in the fixing frame, with the positioning bolt passing through the positioning hole located in the middle of the three sets of positioning holes.

[0006] Preferably, two sets of limiting blocks are fixedly attached to the right side of the fixing frame, and the top block is slidably connected within the limiting blocks.

[0007] Preferably, a buffer pad is tightly fitted to the outer side of the limiting block, and the buffer pad is located on the right side of the top block.

[0008] Preferably, a protective cover is tightly fitted to the right side of the fixing frame, and the protective cover is located outside the threaded tube.

[0009] Compared with the prior art, this utility model provides a motor support structure that can be flexibly adjusted, and has the following beneficial effects:

[0010] 1. This flexibly adjustable motor support structure, through the cooperation between the positioning bolts and three sets of positioning holes, allows the operator to change the installation height of the support plate by installing the positioning bolts in the three sets of positioning holes. At the same time, by setting the fixing holes as rectangular holes, the support plate can install different models of motors, solving the problem of poor adaptability of the device, improving its versatility, increasing the scope of use of the device, and bringing convenience to the operator's work.

[0011] 2. This flexibly adjustable motor support structure, by setting a top block and anti-slip pad, can stably lock one set of movable plates in its current position when tightening the two sets of movable plates, restricting the movement of the movable plates. This facilitates the operator's work in installing the positioning bolts into the positioning holes, avoiding the situation where the two sets of movable plates are misaligned during installation, which would prevent the positioning bolts from being installed. This provides convenience for the operator's work, while also enabling the operator to work independently and reducing labor costs. Attached Figure Description

[0017] 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.

[0018] Please see Figure 1-4 This utility model provides a technical solution: a flexibly adjustable motor support structure, including a mounting frame 1, two sets of fixing frames 8 welded inside the mounting frame 1, a support plate 7 slidably connected between the two sets of fixing frames 8, four sets of fixing holes 17 opened inside the support plate 7, a rotary motor 2 fastened to the top of the support plate 7 by locking bolts and fixing holes 17, and a fan blade 3 keyed to the output end of the rotary motor 2. The fixing frames 8 have three sets of positioning holes 9 inside, and two sets of movable plates 14 are fastened to the bottom of the support plate 7. The movable plates 14 are secured by positioning screws. The bolt 10 and the positioning hole 9 are fitted together and fastened to the fixing bracket 8. A bolt pre-drilled hole is provided in the movable plate 14, through which the positioning bolt 10 passes. The fixing hole 17 is a rectangular hole. Three sets of positioning holes 9 are arranged sequentially from top to bottom within the fixing bracket 8, with the positioning bolt 10 passing through the middle positioning hole 9 of the three sets. By setting the fit between the positioning bolt 10 and the three sets of positioning holes 9, the operator can change the installation height of the support plate 7 by installing the positioning bolt 10 in the three sets of positioning holes 9. Simultaneously, by setting the fixing hole 17 to a rectangular shape... The shaped holes allow the support plate 7 to install motors of different models, solving the problem of poor adaptability of the device, improving its versatility, increasing its application range, and bringing convenience to the operator. Two sets of springs 12 are fastened to opposite sides of the two sets of fixing brackets 8. The end of the spring 12 away from the fixing bracket 8 is fastened to the top block 4. An anti-slip pad 13 is fastened to the left side of the top block 4, and a bearing is fastened to the right side of the fixing bracket 8. A threaded tube 19 is fastened to the middle of the bearing, and a handle 6 is fastened to the right end of the threaded tube 19. A sleeve 18 is threaded onto the outer side of the threaded tube 19. Push plates 5 are fastened to both the front and rear sides of the sleeve 18. By setting top blocks 4 and anti-slip pads 13, when fastening the two sets of movable plates 14, the top blocks 4 and anti-slip pads 13 can stably lock one set of movable plates 14 in the current position, restricting the movement of the movable plates 14. This facilitates the operator's work of installing the positioning bolts 10 into the positioning holes 9, avoiding the situation where the two sets of movable plates 14 are misaligned during installation, which would prevent the positioning bolts 10 from being installed. This provides convenience for the operator's work, while also enabling the operator to work independently and reducing labor costs.

[0019] Specifically, in order to prevent the top block 4 from being misaligned, two sets of limiting blocks 15 are tightly fixed on the right side of the fixing frame 8. The top block 4 is slidably connected inside the limiting blocks 15. A buffer pad 11 is tightly fixed on the outside of the limiting blocks 15, and the buffer pad 11 is located on the right side of the top block 4. Thus, the top block 4 can be prevented from being misaligned by the limiting blocks 15.

[0020] Specifically, in order to protect the threaded tube 19, a protective cover 16 is tightly fitted on the right side of the fixing bracket 8. The protective cover 16 is located on the outside of the threaded tube 19, thereby protecting the threaded tube 19.

[0021] During installation, first place the support plate 7 and the movable plate 14 between the two sets of fixed brackets 8, and align the bolt pre-drilled holes on the movable plate 14 with the positioning holes 9. Then, turn the handle 6 to rotate the threaded tube 19. The rotation of the threaded tube 19 will cause the sleeve 18 to move. The movement of the sleeve 18 will cause the push plate 5 to move and push the top block 4. The movement of the top block 4 will cause the anti-slip pad 13 to move and press against the movable plate 14. At this time, one set of movable plates 14 will be locked by the two sets of top blocks 4, and the positioning bolt 10 will pass through. The positioning hole 9 and the bolt pre-drilled hole on the movable plate 14 will allow the positioning bolt 10 to be engaged between a set of fixed brackets 8 and a set of movable plates 14. Then, the other set of handles 6 can be turned to secure the other set of movable plates 14. After the two sets of positioning bolts 10 are engaged in the two sets of fixed brackets 8 and the two sets of movable plates 14 respectively, the nuts can be tightened to secure the support plate 7 through the positioning bolts 10, so that the support plate 7 is stably installed in the current position. The rotary motor 2 can then be secured to the support plate 7 through the cooperation between the locking bolt and the fixing hole 17.

[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
