Description

Technical Field

[0001] This invention relates to the field of fan technology, and more particularly to a fan grille structure. Background Technology

[0002] A fan guard is a metal protective device installed around a cooling fan. Its main functions are to prevent foreign objects from entering, protect personnel safety, and guide airflow.

[0003] Because fan guards tend to accumulate dust after prolonged use, they need to be removed and cleaned periodically. Existing fan guards are generally fixed with screws, requiring specialized tools for disassembly and reassembly. This is not only cumbersome but also increases the difficulty of cleaning the fan guard. Therefore, we provide a fan guard structure. Summary of the Invention

[0004] To address the problem in the aforementioned background technology that the inconvenience of quickly disassembling the fan guard increases the difficulty of cleaning the fan guard, the present invention provides a fan guard structure.

[0005] The present invention is achieved by the following technical solution: a fan guard structure, including a front shell made of stainless steel, a rear shell made of stainless steel on one side of the front shell, stainless steel metal wires for protection being fixedly connected circumferentially at equal intervals on both the front shell and the rear shell, a quick-connect assembly for facilitating the disassembly and assembly of the front shell on the rear shell, and a knocking dust removal assembly for cleaning dust from the surface of the rear shell.

[0006] As a further improvement to the above solution, the quick-connect assembly includes four sets of pins that are equidistantly circumferentially slidably connected to the rear shell. The rear shell is also equidistantly circumferentially slidably connected to four sets of movable rods. The movable rods and the pins on the same side are symmetrically hinged to two sets of connecting rods via hinges. A spring is sleeved on the outside of the movable rod, and one end of the spring is fixedly connected to the rear shell. A pull handle is fixedly connected to the end of the movable rod. Four sets of connecting posts are equidistantly circumferentially fixedly connected to the outside of the front shell. A push rod is fixedly connected to the end of the connecting post, and a slot matching the pin is provided on the push rod.

[0007] As a further improvement to the above solution, the tapping dust removal assembly includes four sets of connecting frames that are equidistantly and circumferentially fixed to the rear shell. Connecting rods are rotatably connected to the connecting frames via rotating shafts. A tapping ball made of rubber is fixedly connected to the end of the connecting rod and the tapping ball is in contact with a metal wire. A cross-shaped through groove is opened on the connecting rod and a movable rod passes through the through groove. Columns are fixedly connected to both sides of the movable rod and the column rods are slidably connected to the through groove.

[0008] As a further improvement to the above solution, the tapping dust removal assembly also includes four sets of slide rods that are equidistantly and circumferentially fixed to the rear shell. A slider is slidably connected to the outside of the slide rod. Two sets of adjusting rods are symmetrically hinged between the slider and the connecting rod on the same side through a hinge. A second spring is also sleeved on the outside of the slide rod, and one end of the second spring is fixedly connected to the slider on the same side.

[0009] As a further improvement to the above solution, an outer reinforcing ring made of stainless steel and an inner reinforcing ring made of stainless steel are fixedly connected to the outside of the metal wire to improve the strength of the metal wire, and an outer fixing ring is also fixedly connected to the outside of the metal wire on the front shell.

[0010] As a further improvement to the above solution, a connection port is provided on the rear shell, and a cylindrical connector is fixedly connected to the outside of the connection port. The connector is provided with screw holes equidistantly circumferentially for connecting and fixing the rear shell and the fan.

[0011] As a further improvement to the above solution, the ends of the pin and the push rod are both designed with bevels. The inclination angle of the bevel at the end of the pin is the same as that of the bevel at the end of the push rod, both being 45°. The surfaces of the bevels at the end of the pin and the end of the push rod are both smooth surfaces.

[0012] As a further improvement to the above solution, a fixing ring is fixedly sleeved on the outside of one end of the movable rod, and the fixing ring is fixedly connected to the other end of the spring.

[0013] As a further improvement to the above solution, a limiting plate is fixedly connected to the end of the column rod to prevent the column rod from separating from the through groove.

[0014] As a further improvement to the above solution, the end of the slide bar is fixedly connected to a fixing plate for preventing the slider from detaching from the slide bar, and the fixing plate is fixedly connected to the other end of the spring.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0016] 1. In the process of fastening the front shell onto the rear shell, after the push rod on the front shell contacts the pin on the rear shell, as the front shell continues to approach, the push rod can push the pin to move into the rear shell under the cooperation of the inclined surfaces at the ends of the push rod and the pin. At this time, the hinge between the pin and the movable rod and the connecting rod, and the sliding cooperation between the movable rod and the rear shell, can squeeze the movable rod to move outward of the rear shell and compress the first spring. When the pin is aligned with the slot, the spring's own rebound action will cause the pin to automatically insert into the slot, thereby achieving rapid fixation of the front shell and making it highly practical.

[0017] 2. In this invention, during the process of the push rod pressing the pin into the rear housing, the movement of the movable rod can also drive the column rod to move together. Utilizing the sliding fit between the column rod and the through groove, and the rotational fit between the connecting rod and the connecting frame, the connecting rod can be driven to deflect outward. At this time, the striking ball will move away from the metal wire. Simultaneously, utilizing the sliding fit between the sliding rod and the slider, and the hinged fit between the slider, the connecting rod, and the adjusting rod, the connecting rod will push the slider to compress the second spring when it deflects. When the pin is inserted into the slot, the movable rod will drive the column rod to return to its original position under the rebound action of the first spring. Utilizing the rebound action of the second spring, the striking ball will also automatically return to its original position and strike the metal wire. The stainless steel metal wire will deform and quickly recover after being impacted, generating vibration, thereby shaking off the dust on the metal wire of the rear housing, further improving the practicality of the device.

[0018] 3. By pulling outwards on four sets of handles, the four sets of pins can be removed from the slots, making it easy to quickly disassemble the front cover and thus convenient for cleaning.

[0019] 4. By setting an outer reinforcing ring and an inner reinforcing ring made of stainless steel, the present invention can increase the overall strength of the rear shell metal wire, thereby preventing it from deforming when impacted. Attached Figure Description

[0029] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] Example 1:

[0031] Please combine Figure 1-7 This embodiment of a fan guard structure includes a stainless steel front shell 1, a stainless steel rear shell 2 on one side of the front shell 1, stainless steel wires 3 for protection that are circumferentially fixedly connected at equal intervals on both the front shell 1 and the rear shell 2, a quick-connect assembly for easy disassembly and assembly of the front shell 1, a dust removal assembly for cleaning dust from the surface of the rear shell 2, a connection port on the rear shell 2, and a cylindrical connector 7 fixedly connected to the outside of the connection port. The connector 7 has screw holes 8 circumferentially opened at equal intervals for connecting and fixing the rear shell 2 to the fan.

[0032] The quick-connect assembly includes four sets of pins 101 equidistantly circumferentially slidably connected to the rear shell 2. Four sets of movable rods 102 are also equidistantly circumferentially slidably connected to the rear shell 2. Two sets of connecting rods 103 are symmetrically hinged between the movable rods 102 and the pins 101 on the same side via hinges. A spring 104 is sleeved on the outside of the movable rod 102, and one end of the spring 104 is fixedly connected to the rear shell 2. A pull handle 105 is fixedly connected to the end of the movable rod 102. Four sets of connecting posts 106 are equidistantly circumferentially fixedly connected to the outside of the front shell 1. A push rod 107 is fixedly connected to the end of 6. A slot 108 matching the pin 101 is provided on the push rod 107. The ends of both the pin 101 and the push rod 107 are designed with bevels. The inclination angle of the bevel at the end of the pin 101 is the same as that of the bevel at the end of the push rod 107, and both are 45°. The surfaces of the bevels at the ends of the pin 101 and the push rod 107 are smooth. A fixing ring 109 is fixedly sleeved on one end of the movable rod 102, and the fixing ring 109 is fixedly connected to the other end of the spring 104.

[0033] The tapping dust removal assembly includes four sets of equidistant circumferentially fixed connecting frames 201 on the rear shell 2. Connecting rods 202 are rotatably connected to the connecting frames 201 via rotating shafts. A rubber tapping ball 203 is fixedly connected to the end of the connecting rod 202 and the tapping ball 203 is in contact with the metal wire 3. A cross-shaped through groove 204 is opened on the connecting rod 202 and the movable rod 102 passes through the through groove 204. Column rods 205 are fixedly connected to both sides of the movable rod 102 and are slidably connected to the through groove 204. A limiting plate 210 is fixedly connected to the end of the column rod 205 to prevent the column rod 205 from separating from the through groove 204. A fixing plate 211 is fixedly connected to the end of the sliding rod 206 to prevent the slider 207 from separating from the sliding rod 206 and the fixing plate 211 is fixedly connected to the other end of the spring 209.

[0034] The knocking dust removal assembly also includes four sets of slide rods 206 that are equidistantly and circumferentially fixed to the rear shell 2. A slider 207 is slidably connected to the outside of the slide rod 206. Two sets of adjusting rods 208 are symmetrically hinged between the slider 207 and the connecting rod 202 on the same side through a hinge. A second spring 209 is also sleeved on the outside of the slide rod 206, and one end of the second spring 209 is fixedly connected to the slider 207 on the same side.

[0035] The implementation principle of a fan guard structure in this embodiment is as follows: the rear shell 2 is connected and fixed to the fan with screws. The push rod 107 on the front shell 1 is aligned with the pin 101 on the same side and fastened to the rear shell 2. During the process of fastening the front shell 1 to the rear shell 2, after the push rod 107 on the front shell 1 contacts the pin 101 on the rear shell 2, as the front shell 1 continues to move closer, and with the cooperation of the inclined surfaces at the ends of the push rod 107 and the pin 101, the push rod 107 can push the pin 101 to move into the rear shell 2. At this time, the pin 101 and the movable rod 102 are used to... The hinge between the connecting rods 103 and the sliding fit between the movable rod 102 and the rear shell 2 allow the movable rod 102 to be pushed outwards from the rear shell 2 and compress the spring 104. When the pin 101 is aligned with the slot 108, the spring 104's own rebound action causes the pin 101 to automatically insert into the slot 108, thus achieving rapid fixation of the front shell 1. Furthermore, during the process of the push rod 107 pressing the pin 101 inwards from the rear shell 2, the movement of the movable rod 102 also drives the column rod 205 to move together, utilizing the connection between the column rod 205 and the through slot 204... The sliding engagement between the connecting rod 202 and the connecting frame 201, along with the rotational engagement, allows the connecting rod 202 to deflect outwards. At this time, the striking ball 203 will move away from the metal wire 3. Simultaneously, the sliding engagement between the sliding rod 206 and the slider 207, and the hinged engagement between the slider 207 and the connecting rod 202 and the adjusting rod 208, cause the connecting rod 202 to push the slider 207 to compress the second spring 209 when it deflects. When the pin 101 is inserted into the slot 108, the spring 104's rebound action causes the movable rod 102 to move the column... When rod 205 resets, the rebound action of spring 209 causes the striking ball 203 to automatically reset and strike the metal wire 3. The stainless steel metal wire 3 deforms and quickly recovers after being struck, generating vibration, which shakes off the dust on the metal wire 3 on the rear shell 2. By pulling the four sets of pull handles 105 outward, the four sets of pins 101 can be removed from the slots 108, making it easy to quickly disassemble the front shell 1 and clean it. During this process, the striking ball 203 will also strike the metal wire 3 on the rear shell 2.

[0036] Example 2:

[0037] Based on Example 1, this embodiment further improves upon the following: an outer reinforcing ring 4 and an inner reinforcing ring 5 made of stainless steel are fixedly connected to the outside of the metal wire 3 to improve its strength. An outer fixing ring 6 is also fixedly connected to the outside of the metal wire 3 on the front shell 1. By setting the outer reinforcing ring 4 and the inner reinforcing ring 5 made of stainless steel, the overall strength of the metal wire 3 on the rear shell 2 can be increased, thereby preventing it from deforming when impacted. The outer fixing ring 6 can improve the overall strength of the metal wire 3 on the front shell 1.
