Description

Technical Field

[0001] The utility model relates to the field of centrifugal fans, in particular to a mounting bracket and a centrifugal fan thereof. Background Art

[0002] Centrifugal fans are based on the principle of converting kinetic energy into potential energy. They use a high-speed rotating impeller to accelerate the gas, then slow it down and change the flow direction, so that the kinetic energy is converted into potential energy. Centrifugal fans are usually composed of a casing, a drive shaft and an impeller.

[0003] When the centrifugal fan is installed and used, it is usually supported by a base and a bracket. That is, the bracket is fixedly connected to the casing on the centrifugal fan by bolts. However, when the bracket is connected and fixed to the centrifugal fan casing, multiple bolts are usually used for locking. Therefore, when the centrifugal fan is disassembled and maintained, multiple bolts need to be removed to remove the centrifugal fan from the bracket, which reduces the efficiency of installation or disassembly of the centrifugal fan and is inconvenient to use a card-connected locking method between the bracket and the centrifugal fan.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-3 A mounting bracket shown in the figure comprises a base 1, a support plate 2 is symmetrically fixedly connected to the top of the base 1, a restraining plate 3 is arranged on the top of the support plate 2, a positioning hole is opened on one side of the restraining plate 3, a clamping block 4 is slidably engaged with the inner cavity of the positioning hole, the clamping block 4 is fixedly connected to the housing of the centrifugal fan, so that the centrifugal fan can be slidably engaged with the restraining plate 3 through the clamping block 4, grooves are opened on the opposite sides of the support plate 2 and the restraining plate 3, the support plate 2 and the restraining plate 3 are sleeved with a connecting sleeve 5 through the groove, and the connecting sleeve 5 is connected to the shaft connecting side of the housing of the centrifugal fan, The grooves between the two support plates 2 and the two restraining plates 3 at the top of the base 1 respectively match the connecting sleeve 5 on the centrifugal fan casing and the air inlet of the centrifugal fan casing. A locking assembly 6 is provided on the side between the support plate 2 and the restraining plate 3. The locking assembly 6 is used to clamp and restrain the support plate 2 and the restraining plate 3. The locking assembly 6 locks the support plate 2 and the restraining plate 3, so that the support plate 2 and the restraining plate 3 are in a stable state to clamp and lock the centrifugal fan. The locking assembly 6 is released, and the restraining plate 3 can be removed, thereby installing or disassembling the centrifugal fan.

[0025] In particular, the locking assembly 6 includes a first fixing plate 61, a second fixing plate 62 and a limiting plate 63. The first fixing plate 61 is fixedly connected to one side of the restraining plate 3, the second fixing plate 62 is fixedly connected to one side of the supporting plate 2, the limiting plate 63 is slidably engaged between the first fixing plate 61 and the second fixing plate 62, the second fixing plate 62 is located at the bottom of the first fixing plate 61, the limiting plate 63 is fixedly connected to the bottom of the first fixing plate 61, and a groove is provided on one side of the second fixing plate 62. The outer wall of the limiting plate 63 is slidably engaged with the inner cavity of the groove. Under the action of the clamping block 4, the restraining plate 3 cannot slide directly in the vertical direction relative to the supporting plate 2, and the limiting plate 63 is slidably engaged with the second fixing plate 62, so that the restraining plate 3 at the top of the supporting plate 2 can be clamped and restrained again.

[0026] Furthermore, a locking plate 64 is slidably provided on the side of the second fixing plate 62, a locking hole is provided at the bottom of the first fixing plate 61, the top of the outer wall of the locking plate 64 is slidably engaged with the inner cavity of the locking hole, the top of the side of the second fixing plate 62 is fixedly connected with a first fixing block 65, and the bottom of the side of the second fixing plate 62 is fixedly connected with a second fixing block 66. Both the top of the first fixing block 65 and the top of the second fixing block 66 are provided with connecting holes, the outer wall of the locking plate 64 is slidably engaged with the inner cavity of the connecting hole, and the locking plate 64 limits the horizontal engagement of the first fixing plate 61 at the top of the second fixing plate 62, thereby preventing the first fixing plate 61 from driving the limit plate 63 to slide horizontally and separate from the second fixing plate 62, so that the restraining plate 3 can be locked by the first fixing plate 61, thereby ensuring the stability of the installation of the restraining plate 3.

[0027] Furthermore, a guide rod 67 is symmetrically fixedly connected between the first fixing block 65 and the second fixing block 66, and a connecting block 69 is symmetrically fixedly connected to the outer wall of the locking plate 64. The outer wall of the guide rod 67 is slidably inserted and sleeved with the connecting block 69, and a support spring 68 is slidably sleeved on the outer wall of the guide rod 67. The support spring 68 is located at the bottom of the connecting block 69. The two support springs 68 provide elastic force for the locking plate 64 to move toward the first fixing plate 61 through the connecting block 69, and the support spring 68 acts on the locking plate 64 through the connecting block 69. The elastic force is sufficient to support the weight of the locking plate 64, so that the locking plate 64 and the first fixed plate 61 maintain a stable clamping state. A pull ring 610 is fixedly connected to the bottom of the locking plate 64. The pull ring 610 is used to drive the locking plate 64 to separate from the first fixed plate 61, so that the restraining plate 3 can slide away from the centrifugal fan and separate the restraining plate 3 from the blocking block 4. The restraining plate 3 drives the limit plate 63 and the second fixed plate 62 to slide and separate through the first fixed plate 61. The disassembly of the restraining plate 3 is completed, and the centrifugal fan can be installed or disassembled.

[0028] like Figure 1 As shown, this embodiment provides a centrifugal fan, and the centrifugal fan includes the above-mentioned mounting bracket.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
