Description

Technical Field

[0001] This application relates to the field of industrial fan technology, and in particular to an industrial fan with easily installable blades. Background Technology

[0002] Industrial fans are widely used in large spaces where air quality and human comfort need to be improved, such as industrial plants, logistics and warehousing centers, large workshops, stadiums, exhibition halls, waiting halls, shopping malls and supermarkets, and large-scale farms.

[0003] The blades of a typical industrial fan need to be installed one by one on the mounting base, and they need to be fixed with multiple bolts, making the installation of the blades quite troublesome. Utility Model Content

[0004] To facilitate the installation of industrial fan blades, this application provides an industrial fan with easily installable blades.

[0005] This application provides an industrial fan with easily installable blades, employing the following technical solution:

[0006] An industrial fan with easy-to-install blades includes a mounting base and several blades. The mounting base includes a base and a top seat. The blades include blades and fixing posts. The base is circumferentially provided with several sets of connecting rods for mounting the fixing posts. Each set of connecting rods corresponds to one blade. The fixing posts have several connecting holes at their ends. The fixing posts are mounted on the connecting rods through the connecting holes. The base and the top seat are fixed by a fixing assembly.

[0007] By adopting the above technical solution, when the industrial fan needs to be installed, the base is provided with several sets of connecting rods in the circumferential direction, and the end of the fixing column is provided with several connecting holes. The fixing column is aligned with the connecting rods for installation, and the fan blades are installed quickly. The base and the top are fixed by the fixing components, and there is no need to install and fix the fan blades with bolts, which facilitates the installation of industrial fan blades.

[0008] Optionally, the top seat sidewall is provided with a plurality of mounting slots for accommodating the fixing columns, and the mounting slots are provided one-to-one with the fan blades.

[0009] By adopting the above technical solution, the mounting groove facilitates the accommodation of the fixed column.

[0010] Optionally, a set of the connecting rods may include three connecting rods.

[0011] By adopting the above technical solution, a set of connecting rods includes three connecting rods, which makes the fan blades more securely installed, improves the safety of the fan blades during use, and makes them less likely to fall off.

[0012] Optionally, a positioning block is provided on the side wall of the mounting groove, and a groove is provided on the connecting rod, into which the positioning block is engaged.

[0013] By adopting the above technical solution, the positioning block facilitates the positioning and installation of the connecting rod, and at the same time, the positioning block prevents the fan blade from detaching from the base.

[0014] Optionally, a rubber gasket is provided at the end of the positioning block near the connecting rod, and the rubber gasket abuts against the bottom wall of the groove.

[0015] By adopting the above technical solution, when the positioning block is stuck in the groove, the rubber gasket presses against the fixing post, resulting in a better fixing effect. The fixing post can shake slightly and is not easily damaged.

[0016] Optionally, the mounting groove is an arc-shaped groove, and the arc-shaped surface of the arc-shaped groove is adapted to the side wall of the fixed column.

[0017] By adopting the above technical solution, the arc-shaped groove is more compatible with the fixed column, and the installation is convenient.

[0018] Optionally, the fixing component is provided in several parts, each including a screw and a nut. The base and the top seat are provided with several through holes, each corresponding to a fixing component. The screw passes through the through hole, and the nut is threaded to the screw and abuts against the surface of the base.

[0019] By adopting the above technical solution, the screw and nut ensure a secure installation between the base and the top seat.

[0020] In summary, this application includes at least one of the following beneficial technical effects:

[0021] 1. The fixed column is aligned with the connecting rod for installation. The base and top are fixed by the fixing components. The fan blades are installed quickly without the need to use bolts to install and fix the fan blades, which facilitates the installation of industrial fan blades.

[0022] 2. Positioning blocks are used to prevent the fan blades from detaching from the base;

[0023] 3. The rubber gaskets are used to press the fixing posts together, which improves the fixing effect and allows for some wobbling space to prevent damage. Attached Figure Description

[0029] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0030] This application discloses an industrial fan with easily installable blades. (See also...) Figure 1 , Figure 2 , Figure 3 An industrial fan with easily installable blades includes a mounting base 1 and several fan blades 2. The mounting base 1 includes a base 11 and a top mount 12. A connecting post 7 is fixed to the top mount 12 for connection to a motor or factory ceiling. Each fan blade 2 includes a blade 21 and a fixing post 22, with the blade 21 and fixing post 22 integrally formed. Several sets of connecting rods 3 are circumferentially fixed to the base 11 for mounting the fixing post 22. Each set of connecting rods 3 corresponds to one fan blade 2. Each set of connecting rods 3 includes three connecting rods 3. Several connecting holes 41 are provided at the end of the fixing post 22, through which the fixing post 22 is fitted onto the connecting rods 3.

[0031] Reference Figure 2 , Figure 3 The top seat 12 has several mounting slots 42 circumferentially opened on its side wall for accommodating the fixing column 22. The mounting slots 42 are arranged one-to-one with the fan blade 2. The mounting slots 42 are arc-shaped slots 421, and the arc surface of the arc-shaped slots 421 is adapted to the side wall of the fixing column 22.

[0032] Reference Figure 1 , Figure 2 , Figure 4 The top seat 12 has a receiving groove 8 for accommodating the connecting rod 3. When the base 11 is connected and fixed to the top seat 12, the connecting rod 3 is located in the receiving groove 8. A positioning block 43 is fixed at the bottom of the receiving groove 8. The connecting rod 3 has a groove 44, and the fixing block is locked into the groove 44 of the three connecting rods 3. A rubber gasket 6 is fixed to the end of the positioning block 43 near the end of the connecting rod 3, and the rubber gasket 6 abuts against the bottom wall of the groove 44.

[0033] Reference Figure 1The base 11 and the top seat 12 are fixed by a fixing component 5. Several fixing components 5 are provided, and several through holes are provided on both the base 11 and the top seat 12, with each through hole corresponding to a fixing component 5. The fixing component 5 includes a screw 51 and a nut 52. The screw 51 passes through the through hole, and the nut 52 is threaded onto the screw 51, abutting against the surface of the base 11.

[0034] The implementation principle of an industrial fan with easy-to-install blades according to an embodiment of this application is as follows: When the industrial fan needs to be installed, the fixing post 22 on the blade 2 is aligned with the connecting rod 3 for installation. The fixing post 22 is snapped onto the connecting rod 3. The base 11 and the top seat 12 are fixed by the screw 51 and the nut 52, so that the blade 2 is firmly installed. The blade 2 is installed quickly, without the need to install and fix the blade 2 with bolts, which facilitates the installation of the industrial fan blade 2. The base 11 and the top seat 12 are fixed by the fixing component 5. The screw 51 passes through the through hole, and the nut 52 is threaded to the screw 51, so that the base 11 and the top seat 12 are firmly installed. The industrial fan can be installed with fewer bolts or screws 51, and the overall installation speed of the industrial fan is faster.
