Description

Technical Field

[0001] The invention belongs to the field of blowers, and in particular relates to an adapter device for installing a blower host. Background Art

[0002] The various types of blower equipment that we usually see are usually composed of two parts: an external box and a blower host installed inside. The various types of blower hosts we produce are designed according to actual needs, so they often have different appearances, sizes, and air outlet sizes. The installation positions are also different, and the required outer shells and boxes are also different. This one-machine-one-box design will cause many inconveniences in parts processing, material management, and whole machine assembly, resulting in high difficulty and cost in producing blower equipment. Summary of the invention

[0003] The present invention aims to solve the many inconveniences in parts processing, material management and whole machine assembly caused by the above-mentioned one machine and one box, which leads to the problem of great difficulty and high cost in producing blower equipment.

[0004] The present invention discloses an adapter device for installing a blower main unit, which, after being assembled with the blower main unit, constitutes a complete blower equipment together; the adapter device comprises a box body, the box body having a top plate on the top and a bottom plate on the bottom; the top plate has an exposed external air outlet pipe; the blower main unit has a main unit air outlet pipe, and the blower main unit has a main unit base below; the blower main unit is fixed on the bottom plate of the box body through the main unit base; an adapter-connected transition adapter tube is provided between the main unit air outlet pipe and the external air outlet pipe, and the three sections of air outlet pipes together constitute the air outlet duct of the blower equipment.

[0005] A preferred technical solution is that the main engine air outlet pipe, the external air outlet pipe and the transition adapter pipe are coaxially connected to form an air outlet duct of the blower equipment.

[0006] The optimized design is: a transverse through hole (or a longitudinal through hole) is provided on the main engine base; a longitudinal through hole (or a transverse through hole) is provided on the bottom plate; and a pair of locking bolts and locking nuts are arranged at the intersection of the transverse through hole and the longitudinal through hole to fasten the main engine base to the bottom plate; when the locking nut is loosened, the blower main engine can realize transverse and longitudinal movement on the bottom plate along with the hole.

[0007] A further preferred technical solution is that each of the four corners of the host base has a horizontal through hole, and the four through holes are arranged in the same direction and symmetrically; the base plate is provided with four symmetrically arranged longitudinal through holes that can be placed crosswise with the horizontal through holes on the base; at each intersection of the four horizontal and longitudinal directions, a pair of locking bolts and locking nuts are provided to lock the base to the base plate.

[0008] The process of making a blower device based on the above-mentioned adapter device for installing the blower host is as follows: The first step is to place the blower main unit on the bottom plate of the box body, and visually observe that the transverse through holes on the main unit base and the longitudinal through holes on the bottom plate are basically in a vertically intersecting state; The second step is to insert the locking bolt into the intersection of the transverse through hole and the longitudinal through hole; and then screw the locking nut onto the locking bolt from the bottom of the base plate, but ensure that the base and the base plate are in a relatively movable state; The third step is to move the host base on the bottom plate, and when the axial distance between the host air outlet pipe and the external air outlet pipe is observed to be closest, configure the transition pipe, and ensure that one end of the transition pipe is connected to the external air outlet pipe, and the other end can be connected to the host air outlet pipe, and the three pipes together form the air outlet duct of the blower equipment; The fourth step is to make fine adjustments to the above-mentioned pre-assembly state to all appropriate positions and tighten each part: fix the transition adapter tube to the external air outlet pipe and the main unit air outlet pipe respectively to complete the air outlet duct of the blower equipment; then tighten the locking nut on the locking bolt to fasten the main unit base to the base plate.

[0009] Another technical solution for optimizing the design is to add a nut space groove, which is at least required when the locking nut moves, along the movable range of the locking bolt and the locking nut under the base plate, that is, the nut space groove starts from the edge of the longitudinal through hole on one side of the base plate and ends at the edge of the longitudinal through hole on the other side; the nut space groove is surrounded by nut groove baffles and a nut groove bottom; when the locking nut is not screwed on the locking bolt, it must fall into the nut space groove.

[0010] A further optimized design is that the locking nut is a hexagonal nut, which is clearance-matched with the nut space groove, but the clearance can ensure that the symmetrical two sides of the hexagonal nut can slide smoothly along the nut space groove without rotating.

[0011] A further optimized design is to open a nut entry hole on the bottom plate for inserting the locking nut into the nut space groove, so that the locking nut can slide into the nut space groove from the nut entry hole.

[0012] A further optimized design is that a shifting hole is provided at the bottom of the nut slot, so that the locking nut in the nut space slot can be moved from the outside.

[0013] The process of making a blower device based on the above-mentioned adapter device for installing the blower host is as follows: The first step is to put the locking nut into the nut space slot from the nut entry hole; The second step is to place the blower main unit on the bottom plate of the box body, and visually observe that the transverse through holes on the main unit base and the longitudinal through holes on the bottom plate are basically in a vertically intersecting state; The third step is to insert the locking bolt at the intersection of the horizontal through hole and the longitudinal through hole; then slide the locking nut from the hole at the bottom of the nut groove to just below the locking bolt, but ensure that the main base and the bottom plate are in a relatively movable state. At this time, the locking nut will not rotate in the groove.

[0014] The fourth step is to move the host base on the bottom plate, and when the host air outlet pipe and the external air outlet pipe are visually observed to be coaxial, the transition transfer pipe is configured to ensure that one end of the transition transfer pipe is connected to the external air outlet pipe, and the other end can be connected to the host air outlet pipe, and the three pipes together form the air outlet duct of the blower equipment; The fifth step is to move and fine-tune the above-mentioned pre-assembly state. When all the parts are in the appropriate position, tighten the various parts: fix the transition adapter tube to the external air outlet pipe and the main unit air outlet pipe respectively to complete the air outlet duct of the blower equipment; and tighten the locking bolt through the hole on the bottom of the nut groove to fasten the main unit base to the base plate.

[0015] Through the use of the transition adapter tube in the above technical solution and the cross-setting of the transverse through holes and the longitudinal through holes, the box body can be made a universal part for a variety of blower hosts, greatly saving the parts processing, assembly and management costs of the blower equipment; the setting of the nut space groove also facilitates the placement of nuts and the assembly of the blower, without having to worry about reconfiguring the nuts after losing them, and the clearance fit prevents the locking nut from rotating in the nut space groove, facilitating locking assembly, while preventing the base locking nut from falling off and being sucked into the air inlet of the host during operation, thereby causing damage to the impeller.

[0017] Here are two specific implementation examples: The first embodiment discloses an adapter device for installing a blower host 1, such as Figure 1 As shown, after being assembled with the blower host 1, a complete blower device is formed together; the adapter device includes a box body 2, a top plate 3 is provided on the top of the box body 2, and a bottom plate 4 is provided under the box body 2; an air outlet pipe 5 is exposed on the top plate 3 of the box body; the blower host 1 has an air outlet pipe 6, and a base 7 is provided under the blower host 1; the base 7 of the blower host 1 is fixed on the bottom plate 4 of the box body 2; in this embodiment, the air outlet pipe 6 is coaxial with the air outlet pipe 2, one end of the transition adapter tube 8 matches the outer dimensions of the air outlet pipe 6, and the other end matches the outer dimensions of the air outlet pipe 2, and the three pipes are connected to form an air outlet duct of the blower device.

[0018] like Figure 2 As shown in FIG. 3 , each of the four corners of the base 7 has a transverse through hole 9, and the four transverse through holes 9 are arranged in the same direction and symmetrically; the bottom plate 4 is provided with four symmetrical longitudinal through holes 10 that intersect with the transverse through holes 9 on the base 7; at each intersection of the four transverse and longitudinal directions, a pair of locking bolts 11 and locking nuts 12 are provided to lock the base 7 to the bottom plate 4.

[0019] Assembly process: The first step is to place the blower main unit 1 on the bottom plate 4 of the box body 2. When placing it, pay attention to two points: first, the horizontal through hole 9 on the main unit base 7 and the longitudinal through hole 10 on the bottom plate 4 are in a vertically intersecting state; second, the air outlet pipe 6 of the blower main unit 1 is substantially coaxial with the external air outlet pipe 5 on the box body 2; The second step is to insert the locking bolt 11 at the intersection of the transverse through hole 9 and the longitudinal through hole 10; then screw the locking nut 12 onto the locking bolt 11 from the bottom of the bottom plate 4, but do not tighten it and ensure that the base 7 and the bottom plate 4 are in a relatively movable state; The third step is to configure the transition transfer tube 8 according to the current state, to ensure that one end of the transition transfer tube 8 is connected to the external air outlet pipe 5, and the other end can be connected to the main unit air outlet pipe 6, and the three pipes together form the air outlet pipe of the blower equipment; The fourth step is to make fine adjustments to the above-mentioned pre-assembly state, to all appropriate positions, and to tighten all parts: fix the transition adapter tube 8 to the external air outlet pipe 5, and then connect the main air outlet pipe 6 to the transition adapter tube 8, so that the air outlet pipe of the blower equipment is completed; Step 5: Tighten the locking nut 12 on the locking bolt 11 to fasten the host base 7 to the base plate 4.

[0020] Advantages of this embodiment: Due to the cross-setting of the transverse through holes 9 and the longitudinal through holes 10, the main unit can be moved in the longitudinal and transverse directions. Therefore, blower main units of different shapes can be configured with a transition adapter tube 8, so that the box body 2 becomes a universal part, which greatly facilitates the parts processing, whole machine assembly and management cost saving of the blower equipment.

[0021] Second embodiment: like Figure 4 , Figure 5 On the basis of the first embodiment, a nut space slot 13 which is at least required for the locking nut to move is provided below the base plate 4 along the range of motion of the locking bolt 11 and the locking nut 12. The length of the nut space slot 13 starts from the edge of the longitudinal through hole 10 on one side of the base plate 4 and ends at the edge of the longitudinal through hole 10 on the other side. The nut space slot 13 is surrounded by baffles 14 and a nut slot bottom 15. When the locking nut 12 is not screwed onto the locking bolt 11, it must fall into the nut space slot 13. In this embodiment, a nut entry hole 16 is provided on the base plate 4 for inserting the locking nut 12 into the nut space slot 13, so that the locking nut 12 can slide into the nut space slot 13 from the nut entry hole 16. In addition, the locking nut in this embodiment is a hexagonal nut and is clearance-matched with the nut space slot, which can ensure that the symmetrical sides of the hexagonal nut can slide smoothly along the nut space slot without rotating. Figure 5 A shifting hole 17 is provided at the bottom 15 of the nut space groove 13 , and the locking nut 12 in the nut space groove 13 can be shifted from the outside through the shifting hole 17 so as to tighten the locking screw 11 .

[0022] The assembly process of the second embodiment is as follows: first, the locking nut 12 is placed into the nut space groove 13 from the nut entry hole 16; then, the entire assembly process of the first embodiment is performed.

[0023] The advantages of the second embodiment: not only does it have all the advantages of the first embodiment, but also the locking nut 12, whether it is screwed on the locking bolt 11 or not, will not be lost once it enters the nut space groove 13; and through the dial hole 17, it is easy to align the locking nut 12 with the locking bolt 11, and the clearance fit ensures that the locking nut will not rotate, so there is no need to clamp the locking nut with tools, which facilitates assembly and easily ensures the assembly effect, while preventing the base locking nut from falling off and being sucked into the main unit air inlet during the operation of the main unit, thereby causing damage to the impeller.

[0024] The advantage of the present invention is that it solves the inconvenience and high cost of parts processing and management of the original one machine one box, and cleverly makes the outer box body a universal box body for a variety of blower mainframes, which greatly facilitates parts processing, assembly and management, and saves production costs; the configuration of the nut space groove also facilitates the assembly and placement of the locking nut, and there is no need to worry about reconfiguring the nut after losing it; the clearance fit in the nut space groove ensures that the locking nut slides and does not rotate, omitting external tools and quickly and accurately ensuring the assembly effect.
