Technical Field

The utility model relates to the technical field of mechanical structures, in particular to a fan testing tool.

Background

In the design production process of the fan, frequent test tests are required to be carried out on the fan so as to detect the air quantity, noise and other performance parameters of the fan.

In the process of testing the fan, the wall of the test chamber is provided with a vent communicated with the air inlet chamber and the air outlet chamber. Therefore, it is required to seal the wall mounted at the vent using a fan test fixture, then mount the air guide rings of the fan on the fan test fixture, and test the performance parameters of the fan by rotation of the blades located between the air guide rings.

The wind guide rings of different fans have different diameters or side length dimensions. Under the condition that the size of the ventilation opening is fixed, if performance parameters of fans with different sizes of the air guide rings are required to be tested, fan test tools with corresponding sizes are required to be arranged corresponding to the air guide rings with different sizes, and the fan test tools are used for accurately mounting the air guide rings and the ventilation opening. When the fans with different wind guide ring sizes are tested, the fan test tools with different sizes are required to be positioned and installed.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

some embodiments of the utility model provide a fan testing tool, which comprises a frame, a first middle baffle plate and a second middle baffle plate. Along a first straight line direction, the frame forms a containing cavity with two sides open. The first middle partition is positioned in the accommodating cavity, and the edge of the first middle partition, which is close to the frame, is connected with the frame. The first middle partition plate is provided with a first mounting hole along a first straight line direction. The second middle partition is positioned in the accommodating cavity, and the second mounting hole is formed in the second middle partition along the first straight line direction. The second septum has a size greater than the size of the first mounting hole and a size less than the size of the first mounting hole.

Referring to fig. 1, fig. 1 is a schematic perspective view of a first fan testing tool 100 according to an embodiment of the present application. The fan testing tool 100 may include a frame 1 and a first middle partition board 2, where the frame 1 may enclose an accommodating cavity 11 with two open sides along a first straight line direction, the first middle partition board 2 is located in the accommodating cavity 11, and an outer edge of the first middle partition board 2, which is close to the frame 1, may be connected with the frame 1, so that the first middle partition board 2 may be stably connected in the accommodating cavity 11 enclosed by the frame 1. Taking the first straight line direction as the front-rear direction as an example, the first middle partition plate 2 may be provided with the first mounting hole 21 along the front-rear direction. Referring to fig. 2, fig. 2 is a schematic perspective view of the fan test fixture 100 shown in fig. 1 with a fan 200 mounted thereon. When the fan test fixture 100 is used, the air guide ring 201 of the fan 200 can be arranged in the accommodating cavity 11 from back to front, and the front end of the air guide ring 201 can be connected and installed with the edge of the first middle partition plate 2, which is close to the first mounting hole 21, so that an air flow channel surrounded by the air guide ring 201 can be communicated with the first mounting hole 21. The front end of the frame 1 can then be mounted on the wall of the laboratory provided with a vent opening, which can be brought into aligned communication with the front opening of the receiving chamber 11. In this way, the blades of the fan 200 can rotate rapidly in the air guide ring 201 under the driving of the fan, so as to drive the air flow to circulate between the air inlet chamber and the air outlet chamber through the ventilation opening, so as to facilitate the detection of the performance parameters of the fan 200.

The size of the vent opening formed in the wall of the laboratory is determined. In the process of performing test on fans 200 with different sizes of the air guide ring 201, the air guide ring 201 may be installed at the first installation hole 21 of the first middle partition plate 2 with a corresponding size, and then the fan test fixture 100 with the fan 200 installed is installed at the vent. In this way, by precisely installing the first middle partition plate 2 and the air guide ring 201, the testing precision of the fan 200 in the testing process is improved.

Based on this, if the wind-guiding rings 201 of the fans 200 to be tested have a plurality of different sizes, in order to ensure the accuracy of the test, the fan test fixture 100 including the first middle partition plate 2 having a corresponding size is required to be provided corresponding to each of the wind-guiding rings 201 having a different size. Thereby avoiding test errors caused by the fact that the air guide ring 201 is not in place due to poor installation accuracy. That is, when the fans 200 with different wind-guiding rings 201 are tested, the fan test tools 100 with different sizes need to be adapted for positioning and mounting.

Based on this, as shown in fig. 3, fig. 3 is a schematic diagram of an explosion structure of a second fan testing tool 100 according to an embodiment of the present application. The fan test fixture 100 may further include a second middle partition 3, the second middle partition 3 may be provided with a second mounting hole 31 in a front-rear direction, and the second middle partition 3 may be mounted in the accommodating cavity 11. Wherein the second barrier 3 may have a size larger than the first mounting hole 21 and the second mounting hole 31 may have a size smaller than the first mounting hole 21. In this way, during the process of installing the second septum 3, the outer side edge of the second septum 3 away from the second mounting hole 31 can be detachably connected to the inner side edge of the first septum 2 near the first mounting hole 21.

Thus, when the fan test tool 100 provided in the embodiment of the present application is adapted to install the air guide ring 201, since the inner edge of the first middle partition plate 2 close to the first installation hole 21 may be used to install the air guide ring 201, and the inner edge of the second middle partition plate 3 close to the second installation hole 31 may also be used to install the air guide ring 201. Based on this, if the wind-guiding ring 201 has a larger size, and the size of the wind-guiding ring 201 can be adapted to the size of the inner edge of the first middle partition 2 near the first mounting hole 21, the second middle partition 3 can be directly mounted at the inner edge of the first middle partition 2 near the first mounting hole 21 without mounting the second middle partition 3 in the accommodating cavity 11. If the wind-guiding ring 201 has a smaller size, the size of the wind-guiding ring 201 may be adapted to the size of the inner edge of the second partition 3 near the second mounting hole 31. In this way, after the second intermediate partition 3 is mounted at the inner side edge of the first intermediate partition 2 near the first mounting hole 21, the smaller-sized wind guide ring 201 can be mounted at the inner side edge of the second intermediate partition 3 near the second mounting hole 31. That is, through the second middle partition plate 3 which is detachably connected, the fan test tool 100 provided in the embodiment of the application can be adapted to install air guide rings with various sizes and specifications, and has a larger application range.

With continued reference to fig. 3, for the detachable connection between the first intermediate partition 2 and the second intermediate partition 3, a plurality of first positioning holes 22 may be opened in the front-rear direction at the inner side edge of the first intermediate partition 2 near the first mounting hole 21. The plurality of first positioning holes 22 may be spaced around the first mounting hole 21. Correspondingly, a plurality of first connection holes 32 may be formed in the outer edge of the second partition plate 3 away from the second mounting hole 31 in the front-rear direction. Thus, if the second septum 3 is to be mounted at the first mounting hole 21 of the first septum 2, one first connecting hole 32 may be disposed in alignment with one first positioning hole 22 in the front-rear direction when the edge of the second septum 3 away from the second mounting hole 31 is brought closer to the edge of the first septum 2 closer to the first mounting hole 21 from the rear to the front so that the edge of the second septum 3 away from the second mounting hole 31 overlaps with the edge of the first septum 2 closer to the first mounting hole 21. Thus, a first connecting hole 32 and a first positioning hole 22 can be screwed into one another from the back to the front by means of screws or bolts for the detachable connection between the second intermediate partition 3 and the first intermediate partition 2.

It should be noted that, in the above embodiment, among the plurality of first positioning holes 22 formed in the inner edge of the first middle barrier 2, a part of the first positioning holes 22 may be used for the detachable connection of the second middle barrier 3. In the case where the wind-guiding ring 201 can be directly connected to the first intermediate separator plate 2, part of the first positioning holes 22 may also be disposed in alignment with the connection through holes on the wind-guiding ring 201, and may be used for detachable connection between the wind-guiding ring 201 and the first intermediate separator plate 2 by bolts or screws.

In other embodiments, when the first middle separator 2 and the second middle separator 3 are installed in a connecting manner, a clamping groove is formed on one side of the inner side edge of the first middle separator 2, and a buckle which is correspondingly clamped with the clamping groove is formed on the corresponding outer side edge of the second middle separator 3. In this way, one of the outer edges of the second septum 3 and one of the inner edges of the first septum 2 may be mounted by a snap fit connection between the snap and the snap groove. The first connecting hole 32 and the first positioning hole 22 can then be screwed into one another on the opposite side by means of screws or bolts, as can the detachable connection between the first intermediate partition 2 and the second intermediate partition 3.

When the second middle partition plate 3 is connected to and installed with the wind guiding ring, as shown in fig. 3, a plurality of second positioning holes 33 may be formed at the inner edge of the second middle partition plate 3 near the second installation hole 31 along the front-rear direction, and the plurality of second positioning holes 33 may be distributed at intervals around the second installation hole 31. When the second septum 3 is attached to the inner side edge of the first septum 2, the inner side edge of the second septum 3 may be overlapped with the air guide ring 201 (shown in fig. 2) in the front-rear direction, and one of the second positioning holes 33 may be aligned with one of the attachment through holes (not shown in the drawings) on the air guide ring 201, and then the air guide ring 201 and the second septum 3 may be detachably attached by bolts or screws.

In the embodiment of the present application, the cross-sectional shape of the frame 1 in the direction perpendicular to the first straight line may be a polygonal structure such as a triangle, a rectangle, a square, a pentagon, or the like, and the cross-sectional shape of the frame 1 may be a circular or oval structure.

Illustratively, as shown in fig. 4, fig. 4 is a schematic view of an exploded structure of the frame 1 shown in fig. 3. Taking the example that the frame 1 is a rectangular structural body, the frame may include four frame plates 12 and a rectangular frame 13. The four frame plates 12 can be connected end to end in sequence and enclose a receiving cavity 11 with a rectangular cross-sectional shape. The four frame plates 12 may be four rectangular plate structures, one end of one frame plate 12 may be fixedly connected with an adjacent frame plate 12 through a welding process, or may be detachably connected through a threaded hole structure and a screw, and the other end of the frame plate 12 may be fixedly connected or detachably connected with an adjacent other frame plate 12. In addition, the four frame plates 12 may be of an integral structure, that is, an integral strip plate may be bent multiple times and form four frame plates 12 connected end to end in sequence, and two ends of the strip plate may be fixedly connected through a welding process so as to enclose an accommodating cavity 11 having two opposite openings in the front-rear direction.

Since the frame 1 is required to be mounted on a wall body at a vent hole communicating the air inlet chamber and the air outlet chamber in application, the contact connection between the frame 1 and the wall body is facilitated. With continued reference to fig. 4, a rectangular frame 13 may be connected to one end of the four side frame plates 12 in the front-rear direction, for example, one rectangular frame 13 may be connected to the front ends of the four side frame plates 12. The rectangular frame 13 may be provided with a rim opening 14 communicating with the accommodating cavity 11, when the front end of the frame 1 is close to the wall body at the air vent from back to front, the rectangular frame 13 may be contacted with the wall body, and the detachable connection between the frame 1 and the wall body may be realized by a plurality of first rim holes 15 formed in the rectangular frame 13 along the front-back direction and cooperating with screws.

In addition, in the embodiment of the present application, since the fan test fixture 100 can be adapted to install different sizes of the air guide ring 201. Therefore, when the fan test fixture 100 is installed at the vent, the frame 1 may be directly fixed to the edge of the vent by gluing or welding, which is not limited in this application.

In the embodiment of the present application, a certain installation tightness needs to be ensured when the rectangular frame 13 is connected to the wall body at the edge of the vent. Correspondingly, when the air guide ring 201 is installed, a certain installation tightness is required to be provided between the air guide ring 201 and the middle partition plate, so that the test precision of the fan is improved. Based on this, the sealing connection between the rectangular frame 13 and the wall body can be satisfied by providing a sealing rubber ring in a compressed state between the rectangular frame 13 and the wall body. Correspondingly, a sealing rubber ring in a compressed state can be arranged between the air guide ring 201 and the middle partition plate in a cushioning mode so as to meet the sealing connection between the air guide ring 201 and the middle partition plate. In addition, the two connected components can be directly bonded by using sealant according to actual conditions, and the two components are connected simultaneously so as to realize sealing connection between the two components. The present application is not limited in this regard.

In some embodiments, when the rectangular frame 13 and the four side frame plates 12 are connected, the rectangular frame 13 and the four side frame plates 12 may be fixedly connected by a welding process. Alternatively, a plurality of frame connection lugs may be connected to the rear of the rectangular frame 13, and since the frame connection lugs may have overlapping portions with the adjacent frame plates 12, the rectangular frame 13 and the four frame plates 12 may be connected by providing through holes and fitting screws. The rectangular frame 13 and the four frame plates 12 may be directly connected by gluing.

As shown in fig. 4, the rectangular frame 13 may be provided to have a large size such that the main structure of the rectangular frame 13 at the front ends of the four side frame plates 12 is located outside the accommodating chamber 11. I.e. the main structure of each side edge of the rectangular frame 13 may be located on the side of the adjacent one of the rim plates 12 remote from the receiving cavity 11. In this way, when the frame 1 is mounted on the wall body at the ventilation opening, the rectangular frames 13 located outside the four side frame plates 12 facilitate the mounting operation of the frame 1.

In addition, the rectangular frame 13 may be provided with a small size so that the rectangular frames 13 located at the four side plates 12 and Qian Dun have their main structures located in the accommodating chambers 11. I.e. the main structure of each side edge of the rectangular frame 13 may be located on the side of the adjacent one of the border plates 12 facing the receiving chamber 11. As shown in fig. 4, when the frame is mounted on the wall body at the ventilation opening, the rectangular frames 13 positioned inside the four rim plates 12 have a smaller occupation space when contacting the wall body.

Between the frame 1 and the first middle partition plate 2, the edge of the first middle partition plate 2 far away from the first mounting hole 21 and the frame 1 can be fixedly connected through a welding process, and the frame 1 and the first middle partition plate 2 can also be connected in a detachable mode.

Illustratively, as shown in fig. 5, fig. 5 is a rear view of the first and second baffles 2, 3 shown in fig. 3. Taking the first intermediate partition plate 2 and the frame 1 as an example, they may have a rectangular or other quadrangular structure. The fan test fixture 100 provided in this embodiment may further include at least four connecting ribs 4, and the first middle partition plate 2 is far away from four outer side edges of the first mounting hole 21, and may be connected with and mounted on at least one connecting rib 4 at each outer side edge. For example, a connecting rib 4 may be installed in front of the four outer edges of the first intermediate partition 2, respectively. It is also possible to mount a connecting rib 4 behind each of the four outer edges of the first intermediate partition 2.

Alternatively, as shown in fig. 6, fig. 6 is a cross-sectional view taken along line A-A in fig. 5, the number of the connecting ribs 4 may be eight, that is, at four outer edges of the first middle separator 2, one connecting rib 4 may be installed at each of front and rear sides of each outer edge.

It should be noted that the connecting rib 4 may be a flange structure, that is, four outer edges of the first middle partition plate 2 may be bent forward or backward to form one connecting rib 4 of a flange structure. Furthermore, the connecting ribs 4 may also be elongated connecting elements and may be fixedly connected to the outer edge of the first intermediate separator 2 by means of a welding process.

In the case of the first intermediate partition 2 being mounted and connected, as shown in fig. 3 and 5, both the connecting ribs 4 and the first intermediate partition 2 can be located in the receiving space 11, i.e. one connecting rib 4 can be located on the side of the adjacent one of the frame plates 12 facing the receiving space 11. Based on this, as shown in fig. 4, a plurality of second frame holes 16 may be formed in the frame plate 12 in a direction perpendicular to one frame plate 12. Referring to fig. 6, a connecting rib 4 adjacent to the frame plate 12 may be provided with a rib hole 41 corresponding to a second frame hole 16. In this way, the first intermediate partition 2 and the frame 1 can be detachably connected by screwing in the aligned rib hole 41 and second frame hole 16 in order by means of screws or bolts for connecting the frame plate 12 to the connecting rib 4.

Since the second intermediate partition 3 and the first intermediate partition 2 can be aligned and connected through the first positioning hole 22 and the first connecting hole 32. Based on this, as shown in fig. 7, fig. 7 is a partially enlarged schematic view at B in fig. 6. In the front-rear direction, a first positioning groove 23 is provided on the side of the edge of the first middle barrier 2 near the first mounting hole 21 near the second middle barrier 3. Taking the example that the second middle separator 3 is mounted close to the first middle separator 2 from the rear to the front, the first positioning groove 23 may be opened at the rear side of the inner side edge of the first middle separator 2. I.e. the first positioning groove 23 may be an annular groove structure continuously distributed around the first mounting hole 21. Wherein the first positioning groove 23 may be used for positioning installation of the second septum 3 or the wind deflector 201 (as shown in fig. 2).

Illustratively, the first positioning groove 23 may be sized slightly larger than the second septum 3, and the second septum 3 may be positioned just inside the first positioning groove 23 and one of the first positioning holes 22 may be aligned with one of the first connecting holes 32 when the second septum 3 is mounted from the back to the front near the first septum 2. It is also possible to align one of the first positioning holes 22 with one of the first connecting holes 32 after trimming. So as to connect the first and second intermediate partitions 2 and 3 by screws or bolts.

In addition, the first positioning groove 23 may have a larger structural dimension than the wind guide ring 201. If the air guide ring 201 with a corresponding size can be directly installed at the inner side edge of the first middle partition plate 2, when the air guide ring 201 is installed close to the first middle partition plate 2 from back to front, the air guide ring 201 can be just placed in the first positioning groove 23, and one first positioning hole 22 can be aligned with one connecting through hole of the air guide ring 201. It is also possible to align one of the first positioning holes 22 with one of the connecting through holes of the wind-guiding ring 201 after fine adjustment. So as to connect the first intermediate baffle 2 and the wind-guiding ring 201 by means of screws or bolts.

It should be noted that, on the first middle separator 2, the first positioning groove 23 may be a groove structure having a rear side opening, such as the inner side edge of the first middle separator 2 is reduced in thickness from rear to front to form the first positioning groove 23 of the groove structure. For example, the thicknesses of the first and second intermediate separators 2, 3 in the front-rear direction may be 6mm. A first positioning groove 23 of 3mm depth may be provided at the inner edge of the first intermediate separator 2.

Based on this, with continued reference to fig. 7, a side of the second septum 3 facing the first positioning groove 23 in the front-rear direction, which is away from the outer edge of the second mounting hole 31, is provided with a first concave portion 34. If the first positioning groove 23 is opened at the rear side of the inner edge of the first middle barrier 2, the first recess 34 may be opened at the front side of the outer edge of the second middle barrier 3.

In this way, during the process of installing the second middle partition plate 3 from back to front, the first concave part 34 and the first positioning groove 23 are matched for installation, so that the second middle partition plate 3 and the first middle partition plate 2 have more obvious positioning depth when in positioning installation, namely the positioning installation is more convenient.

In the above embodiment, the first positioning groove 23 is formed by the inward side edge of the first middle barrier 2 being recessed forward, and the first recessed portion 34 is formed by the outward side edge of the second middle barrier 3 being recessed rearward. On this account, in the case where the thicknesses of the first and second intermediate separators 2, 3 in the front-rear direction are 6mm, the first positioning groove 23 may be provided to have a depth of 3mm, and the corresponding first recess 34 may be provided to have a depth of 3mm as well. In this way, when the second middle partition 3 is mounted at the inner side edge of the first middle partition 2, the front side wall of the first middle partition 2 can be aligned with the front side wall of the second middle partition 3, and the rear side wall of the first middle partition 2 can be aligned with the rear side wall of the second middle partition 3, so that a better mounting effect can be achieved.
