Description

Technical Field

[0001] The utility model relates to the technical field of motors, and in particular to a cross-flow fan capable of rapid pre-positioning. Background Art

[0002] A crossflow fan is a fan that exhausts air by creating a vortex through the rotation of an impeller. It has the functions of ventilation, gas transmission, dust removal, and heat dissipation and cooling. The structure of an existing crossflow fan can refer to the Chinese patent announcement number CN205260378U, which discloses a crossflow fan. The crossflow fan includes a motor, an impeller is connected to the output shaft of the motor, a cover is provided outside the impeller, an air inlet and an air outlet are provided on the cover, and connecting plates are protruding from the side ends of both sides of the cover near the air outlet, and positioning holes are opened on the connecting plates.

[0003] When using a crossflow fan for cooling, Figure 1 As shown, an installation window 1 that is connected to the air outlet of the cross-flow fan needs to be set on the device to be cooled. A mounting ring 11 that fits the cover of the cross-flow fan is protruded outwardly around the installation window 1, and screw holes 13 that are aligned with the positioning holes 12 are provided on the installation ring 11; if the installation window 1 is set on the side wall of the device, when the above-mentioned cross-flow fan is installed, the operator needs to hold the cross-flow fan with one hand first, and then screw at least one screw on each side of the cross-flow fan to make it hang on the installation position. The above is the process of pre-positioning the cross-flow fan. The weight of the cross-flow fan is borne by one hand. If the cross-flow fan is too heavy, it will make the operator feel laborious and increase the difficulty of assembly; if the body length of the cross-flow fan is very long, it will increase the difficulty of the operator to screw the screws on both sides for pre-positioning. Therefore, the existing cross-flow fan is difficult to assemble when used for heat dissipation. Utility Model Content

[0004] In view of the disadvantage that the existing crossflow blower is difficult to assemble, the purpose of the utility model is to provide a crossflow blower which can reduce the difficulty of assembly by rapid pre-positioning.

[0005] In order to solve the above technical problems, the utility model is solved by the following technical solutions:

[0006] A crossflow fan capable of rapid pre-positioning comprises a fan body, the fan body comprising a cover shell, a connecting plate integrally arranged around the air outlet of the cover shell, a clamping mechanism capable of clamping a mounting ring so that the fan body is hung on the mounting ring, the clamping mechanism comprising a clamping piece arranged on the connecting plate, and when the connecting plate is in contact with one side of the mounting ring, the clamping piece is located on the other side of the mounting ring and cooperates with the connecting plate to buckle the mounting ring.

[0007] By adopting the above scheme, the fan body in this scheme can clamp the mounting ring on the mounting window through the clamping mechanism before installation, so that it can be hung on the mounting ring for pre-positioning and then locked with screws. Compared with the existing cross-flow fans, the cross-flow fans in this scheme can allow the fan body to be hung on the mounting position before screwing on the screws, eliminating the need for the operator to hold up the fan body while screwing the screws for pre-positioning; when disassembly is required, after the fasteners on the mounting ring and the connecting plate are removed, the fan body is still hung on the mounting ring and will not fall off, which makes the installation or disassembly process more labor-saving and reduces the difficulty of installation and disassembly during subsequent maintenance.

[0008] Preferably, the clamping member includes a bottom plate arranged at the upper end of the connecting plate and an elastic clip formed by bending and extending one end of the bottom plate away from the connecting plate toward the connecting plate. A fitting gap is left between the elastic clip and the connecting plate for the installation ring to be inserted. When the two are plugged into each other, the end of the elastic clip elastically abuts against the installation ring and buckles the installation ring.

[0009] By adopting the above scheme, during installation, the fan body is placed above the mounting ring and moved downward, and the elastic clip is moved to increase the fitting gap. When the mounting ring is inserted into the fitting gap, the elastic clip is released, and the fan body can be hung on the mounting ring by means of the elastic clip to complete pre-positioning. This operation method is more labor-saving and simpler than the existing step of supporting the fan body while screwing screws on both sides thereof.

[0010] Preferably, the clamping member further comprises a guide piece which is arranged to extend downwardly and obliquely from the end of the elastic clip toward a side away from the connecting plate, and when the mounting ring is inserted into the fitting gap, it abuts against the guide piece and gradually opens the elastic clip.

[0011] By adopting the above scheme and based on the above installation method, the guide piece in this scheme can be supported by the edge of the mounting ring and gradually open the elastic clip during the downward movement of the fan body, so that the fitting clearance is increased and it can enter smoothly, eliminating the step of manually opening the elastic clip and making the assembly process simpler.

[0012] Preferably, the clamping member is detachably connected to the connecting plate, and a mounting portion for mounting the clamping member is provided on the connecting plate.

[0013] By adopting the above scheme, in order to avoid the situation where the elastic force of the elastic clip decreases due to long-term use, resulting in the failure of the hanging function, the clamping member in this scheme is detachably arranged on the connecting plate. When the elastic clip fails, the above problem can be solved by simply replacing the clamping member, which is very convenient.

[0014] Preferably, the mounting portion includes a protrusion integrally provided on the connecting plate, a receiving groove recessed on the upper end surface of the protrusion for the bottom film to be embedded in, and a fastening structure for fixing the bottom film in the receiving groove.

[0015] Preferably, the fastening structure includes a through hole provided on the bottom plate, a threaded hole provided at the bottom of the receiving groove, and a screw passing through the through hole and cooperating with the threaded hole.

[0016] Preferably, at least one group of clamping mechanisms is provided along the length direction of the cover shell.

[0017] By adopting the above solution, the more the number of clamping mechanisms is, the more stable the fan body is hung. When only one set of clamping mechanisms is provided on the connecting plate, the clamping mechanisms are located in the middle of the cover.

[0018] Preferably, a storage structure for storing electric wires on the fan body is provided on the cover, and the storage structure includes a wire harness groove provided on the cover.

[0019] The utility model adopts the above technical scheme, which has significant technical effects: before installation, the fan body in the scheme can clamp the mounting ring on the mounting window through the clamping mechanism, so that the fan body is hung on the mounting ring for pre-positioning and then locked with screws. Compared with the existing cross-flow fans, the cross-flow fan in the scheme can make the fan body hang on the mounting position before screwing on the screws, eliminating the need for the operator to hold up the fan body while screwing the screws for pre-positioning; when disassembly is required, after the fasteners on the mounting ring and the connecting plate are removed, the fan body is still hung on the mounting ring and will not fall off, which makes the installation or disassembly process more labor-saving and reduces the difficulty of installation and disassembly during subsequent maintenance.

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0027] Example

[0028] A crossflow fan capable of pre-positioning, according to Figure 1 As shown, the fan body 2 includes a motor 23, a cover 21, and an impeller 24 arranged in the cover 21 and connected to the motor 23. A connecting plate 22 is integrally provided on the cover 21 around the air outlet. In this embodiment, the cover 21 and the impeller 24 are provided on both sides of the motor 23. The above is the prior art.

[0029] The improvement of this embodiment is that the connecting plate 22 is provided with a clamping member 3 for clamping the mounting ring 11 so that the fan body 2 is hung on the mounting ring 11. Figure 1 or Figure 3 As shown, the clamping member 3 includes a bottom plate 31 arranged at the upper end of the connecting plate 22, and one end of the bottom plate 31 away from the connecting plate 22 is bent and extended toward the connecting plate 22 to form an elastic clip 32, and a matching gap for the installation ring 11 to be inserted is reserved between the elastic clip 32 and the connecting plate 22. When the two are plugged into each other, the end of the elastic clip 32 elastically abuts against the installation ring 11 and buckles the installation ring 11, and the end of the elastic clip 32 is inclined downward and extended to the side away from the connecting plate 22 to be provided with a guide piece 33. When the installation ring 11 is inserted into the matching gap, the edge of the installation ring 11 abuts against the guide piece 33 and gradually opens the elastic clip 32.

[0030] The connecting plate 22 is also provided with a mounting portion 4 for mounting the clamping member 3. Figure 3 , Figure 4 or Figure 5 As shown, the mounting portion 4 includes a protrusion 41 integrally provided on the connecting plate 22, and the upper end surface of the protrusion 41 is concavely provided with a receiving groove 42 for the bottom sheet 31 to be embedded, and the mounting portion 4 also includes a fastening structure for fixing the bottom sheet 31 in the receiving groove 42. Figure 5 As shown, the fastening structure includes a through hole 43 opened on the bottom plate 31 , a screw 45 is passed through the through hole 43 , and a threaded hole 44 cooperating with the screw 45 is opened at the bottom of the receiving groove 42 .

[0031] At least one set of the clamping member 3 and the mounting portion 4 is provided along the length direction of the connecting plate 22. Figure 1 As shown, in this embodiment, both ends of the motor 23 of the cross-flow fan are provided with a housing 21 and a connecting plate 22, and a group of clamping members 3 and mounting portions 4 are respectively provided on the connecting plates 22 on both sides.

[0032] according to Figure 1 As shown, a storage structure for storing electric wires on the fan body 2 is provided on the cover 21 , and the storage structure includes a wire harness groove 5 provided on the cover 21 .

[0033] Combined with the above structure, reference Figure 1 to Figure 5 It can be known that the pre-positioning process of a crossflow fan capable of rapid pre-positioning in this embodiment is as follows:

[0034] The operator needs to fit the connecting plate 22 of the fan body 2 with the mounting ring 11 first, and ensure that the clamping member 3 is located above the connecting plate 22, and then slowly move the fan body 2 downward, so that the edge of the mounting ring 11 abuts against the guide piece 33 on the clamping member 3 and gradually opens the elastic clip 32, and the mounting ring 11 can be smoothly inserted into the matching gap formed by the elastic clip 32 and the connecting plate 22. At this time, the clamping member 3 and the connecting plate 22 clamp the mounting ring 11, and the fan body 2 is pre-positioned;

[0035] Compared with the prior art, the above-mentioned pre-positioning process is that the cross-flow fan in this embodiment can allow the fan body 2 to be hung on the installation position before the screws are tightened, eliminating the need for the operator to hold up the fan body 2 and tighten the screws for pre-positioning; when disassembly is required, after the fasteners on the mounting ring 11 and the connecting plate 22 are removed, the fan body 2 is still hung on the mounting ring 11 and will not fall off, which makes the installation or disassembly process more labor-saving, and reduces the difficulty of installation and subsequent disassembly during maintenance, and the operation steps are also very simple.
