[0001] The utility model relates to the technical field of fans, in particular to a protective net for a fan. Background Art

[0002] A fan is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is a driven fluid machine. The fan box is provided with an air inlet for airflow to enter the box. In order to protect the fan, motor and other components inside the fan and not affect the normal use of the fan, a protective net is usually installed at the air inlet to prevent foreign objects from falling into the box and damaging the fan, motor and other components. The existing quick installation device for a fan protective net (Announcement No.: CN215444493U) has the following disadvantages in use:

[0003] During the installation of the protective net, it is first necessary to press the block on the outer wall of the protective net when sliding the slider into the slide groove so that the block can enter the slide groove. However, it is troublesome to send the protective net into the through groove while pressing, and the elasticity of the spring is likely to decrease after long-term use. In order to better fix the protective net, the device and the shell of the outer ring of the protective net need to be replaced, which will waste a lot of materials. For this reason, this patent proposes a protective net for a fan to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a protective net for a fan to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a protective net for a fan, comprising a connecting shell, a mounting shell is installed at one end of the connecting shell, a protective net is installed on the inner wall of the mounting shell, a plug-in is fixed at one end of the protective net, a slot is provided on the outer wall of the plug-in, a plurality of mounting slots are provided inside the mounting shell, a slide is slidably connected in the mounting slot, a plug-in plate is fixed at the bottom end of the slide, the plug-in plate is inserted into the slot after passing through the mounting shell, the bottom of the plug-in plate contacts the outer wall of the plug-in plate away from the protective net, a fixing rod is fixed at the top of the slide, the fixing rod passes through the outer wall of the mounting shell away from the plug-in plate, a spring is fixed at the top of the slide, and the spring is fixed to the top of the mounting slot.

[0006] Preferably, a second connecting plate is fixed to the outer wall of the mounting shell, a first connecting plate is fixed to the outer wall of one end of the connecting shell, a plurality of mounting holes are opened between the second connecting plate and the first connecting plate, bolts are threaded into the mounting holes for fixing the mounting shell and the connecting shell.

[0007] Preferably, a limiting plate is fixed to the inner wall of the mounting shell, the limiting plate is used to limit the plug-in, and one end of the plug-in away from the protective net is in contact with the limiting plate.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The difference between the protective net of the fan and the prior art is that when the protective net needs to be installed, the protective net is inserted into the installation shell by aligning it with the installation shell. During the insertion process, the bottom end of the plug plate contacts the front outer wall of the plug-in. During the movement of the plug-in, the plug plate slides on the surface of the plug-in and is driven to move upward, thereby squeezing the spring. When the spring is squeezed, it drives the fixing rod to move outward. When the plug-in moves to a certain position, the plug plate is just located at the slot. Since the plug plate is no longer squeezed, the spring is not squeezed, thereby driving the slide plate to move toward the plug-in, driving the plug plate to move, so that the plug plate is inserted into the slot to limit the plug-in, thereby fixing the protective net. It is relatively convenient to install, and when the elasticity of the spring decreases in the later stage, the installation shell can be replaced by removing the bolts of the second connecting plate and the first connecting plate, which is relatively convenient. In this way, there is no need to replace the connecting shell in the later stage, thereby avoiding the waste of more materials. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] 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.

[0019] An air inlet is provided on the fan box for air flow to enter the box. In order to protect the fan, motor and other components inside the fan and not affect the normal use of the fan, a protective net 3 is usually installed at the air inlet to prevent foreign objects from falling into the box and damaging the fan, motor and other components. The protective net of the fan provided by the utility model is not only convenient for the installation of the protective net 3, but also convenient for the later disassembly of the protective net 3. In addition, when the protective net 3 is not firmly fixed at the later stage, there is no need to replace the entire outer shell, only the mounting shell 2 needs to be replaced to avoid affecting the installation of the protective net 3.

[0020] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a protective net for a fan, comprising a connecting shell 1, a mounting shell 2 is installed at one end of the connecting shell 1, a protective net 3 is installed on the inner wall of the mounting shell 2, a plug-in 9 is fixed at one end of the protective net 3, a slot 12 is provided on the outer wall of the plug-in 9, a plurality of mounting slots 10 are provided inside the mounting shell 2, a slide plate 13 is slidably connected in the mounting slot 10, a plug-in board 11 is fixed at the bottom end of the slide plate 13, the plug-in board 11 penetrates the mounting shell 2 and is inserted into the slot 12, the bottom of the plug-in board 11 contacts the outer wall of the plug-in 9 away from the protective net 3, a fixing rod 14 is fixed at the top end of the slide plate 13, the fixing rod 14 penetrates the outer wall of the mounting shell 2 away from the plug-in board 11, a spring 16 is fixed at the top end of the slide plate 13, and the spring 16 is fixed to the top end of the slide plate 13, and the spring 16 is fixed to the top end of the mounting slot 10. A fixing plate 15 is fixed at one end of the fixing rod 14, and the fixing plate 15 is located outside the mounting shell 2.

[0021] It should be noted that when the protective net 3 needs to be installed, the protective net 3 is inserted into the installation shell 2 by aligning it with the installation shell 2. During the insertion process, the bottom end of the plug plate 11 contacts the front outer wall of the plug 9. During the movement of the plug 9, the plug plate 11 slides on the surface of the plug 9 and is driven to move upward, thereby squeezing the spring 16. When the spring 16 is squeezed, it drives the fixing rod 14 to move outward. When the plug 9 moves to a certain position, the plug plate 11 is just located at the slot 12. Since the plug plate 11 is no longer squeezed, the spring 16 is not squeezed. The slide plate 13 is pressed, thereby driving the slide plate 13 to move towards the plug-in 9, driving the plug-in board 11 to move, so that the plug-in board 11 is inserted into the slot 12 to limit the plug-in 9, thereby fixing the protective net 3. In addition, when the protective net 3 needs to be replaced later, the fixing plate 15 is pulled outward, and the fixing plate 15 drives the fixing rod 14 to move outward, thereby driving the slide plate 13 and the plug-in board 11 to move away from the plug-in 9, so that the plug-in board 11 moves out of the slot 12 and no longer fixes the plug-in 9, so that the protective net 3 can be taken out.

[0022] like Figure 1 and Figure 2 As shown, a second connecting plate 7 is fixed to the outer wall of the mounting shell 2, and a first connecting plate 5 is fixed to the outer wall of one end of the connecting shell 1. A plurality of mounting holes are provided between the second connecting plate 7 and the first connecting plate 5, and bolts are threaded into the mounting holes for fixing the mounting shell 2 and the connecting shell 1. A limiting plate 8 is fixed to the inner wall of the mounting shell 2, and the limiting plate 8 is used to limit the plug-in 9, and the end of the plug-in 9 away from the protective net 3 is in contact with the limiting plate 8. The other end of the protective net 3 is rotatably connected to a connecting rod 4, and a cleaning brush 6 is fixed to the end of the connecting rod 4 close to the protective net 3, and the cleaning brush 6 is in contact with the other end of the protective net 3 for cleaning the other end of the protective net 3. The protective net 3 is composed of a plurality of round rods and vertical rods, and the plurality of vertical rods are fixed between two adjacent round rods to prevent some larger dust from entering the connecting shell 1.

[0023] It should be noted that when the spring 16, fixing rod 14, slide plate 13 and plug plate 11 are damaged and cannot fix the protective net 3 well, the mounting shell 2 can be replaced by removing the bolts of the second connecting plate 7 and the first connecting plate 5, which is more convenient. In this way, there is no need to replace the connecting shell 1 later. In addition, when dust appears on the other end of the protective net 3, the connecting rod 4 can be rotated, and the connecting rod 4 drives the cleaning brush 6 to clean the other end of the protective net 3.

[0024] Working principle: when the protective net 3 needs to be installed, the end of the protective net 3 fixed with the plug-in 9 is inserted into the mounting shell 2. During the insertion process, the bottom end of the plug-in plate 11 contacts the front outer wall of the plug-in 9. During the movement of the plug-in 9, the plug-in plate 11 slides on the surface of the plug-in 9 and is driven to move upward, thereby squeezing the spring 16. When the spring 16 is squeezed, it drives the fixing rod 14 to move outward. When the plug-in 9 moves to a certain position, the plug-in plate 11 is just located at the slot 12. Since the plug-in plate 11 is no longer squeezed, the spring 16 is not squeezed, thereby driving the slide plate 13 to move toward the direction close to the plug-in 9, driving the plug-in plate 11 to move, so that the plug-in plate 11 is inserted into the slot 12 to limit the plug-in 9, thereby fixing the protective net 3.

[0025] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is limited by the attached embodiments and their equivalents.
