Description

TECHNICAL FIELD

[0001] The present application relates to the field of heat dissipation fan mesh cover, in particular to a tool-free disassembly and washing heat dissipation fan front mesh cover structure. BACKGROUND

[0002] In the use process of the heat dissipation fan, the front mesh cover structure plays a crucial role in protecting the internal components of the fan and preventing foreign matter from entering. However, the traditional heat dissipation fan front mesh cover structure has many inconveniences in terms of disassembly and washing.

[0003] On the one hand, many traditional front mesh covers use tool-fixed methods, such as using a screwdriver or other tools to disassemble and install screws to fix the mesh cover frame and mesh plate. This method not only requires additional tools, but also increases the cost and difficulty of maintenance during operation, as the small size of the screws makes them easy to lose. At the same time, frequent use of tools to disassemble and install screws can also cause the screw holes to wear out, affecting the stability and service life of the mesh cover structure.

[0004] On the other hand, although some traditional front mesh covers attempt to use some simple fixing methods, the fixing effect is often unsatisfactory. For example, the connection between the mesh cover frame and the mounting cover of some structures is not stable enough, and during the operation of the fan, the mesh cover frame is prone to looseness or even falling off due to vibration and other reasons, which not only affects the heat dissipation effect, but also may cause safety hazards to the normal operation of the fan. Moreover, these simple fixing methods, while achieving tool-free disassembly, cannot balance the convenience of disassembly and the firmness after reinstallation, and cannot meet the user's demand for high-quality and easy-to-maintain front mesh cover structure of the heat dissipation fan.

[0005] Therefore, it is of great practical significance to develop a heat dissipation fan front mesh cover structure that can achieve tool-free disassembly and washing while ensuring structural stability and firm installation. SUMMARY

[0006] The purpose of the present application is to provide a tool-free disassembly and washing heat dissipation fan front mesh cover structure to solve the problems raised in the background.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical solution: a tool-free disassembly and washing heat dissipation fan front mesh cover structure, comprising a mounting cover, the inner ring opening of the mounting cover is inserted with a mesh cover frame, the inner ring opening of the mesh cover frame is installed with a mesh plate, the outer ring surface of the mounting cover is provided with an outer ring groove, a plurality of clamping handles are inserted into the surface of the outer ring groove, the clamping handles are inserted into the outer ring surface of the mesh cover frame after penetrating through the mounting cover, a limiting cover is sleeved in the outer ring groove, and the limiting cover blocks the retreat of the clamping handle.

[0008] Preferably, the mounting cover is a circular ring plate with an "L"-shaped cross-section. A plurality of reserved holes are provided on the surface of the mounting cover. An embedding groove is provided at the inner ring opening of the mounting cover. A rubber ring is fixed on the outer ring surface of the embedding groove. The net cover frame is inserted into the embedding groove, and the rubber ring is clamped between the embedding groove and the outer ring surface of the net cover frame to generate elastic deformation.

[0009] Preferably, an installation groove is provided at the inner ring opening of the net cover frame. The net plate is inserted into the installation groove, and a clamping plate is inserted into the installation groove. The clamping plate is a circular ring plate, and the inner ring diameter of the clamping plate is equal to the inner ring diameter of the net cover frame. A hand-tightening screw is screwed on the surface of the clamping plate. The hand-tightening screw penetrates through the clamping plate and the net plate and is screwed on the surface of the installation groove.

[0010] Preferably, a clamping groove is provided on the outer ring surface of the net cover frame. The clamping groove is an annular groove. After the limiting cover pushes the clamping handle to stretch the rubber ring, it is inserted into the clamping groove.

[0011] Preferably, a plurality of insertion holes are provided on the inner ring surface of the outer ring groove. The clamping handle and the insertion holes correspond one by one. The clamping handle is inserted into the insertion hole, and the height of the clamping handle is greater than the depth of the insertion hole. One end of the clamping handle is fixed on the outer ring surface of the rubber ring, and the other end of the clamping handle is provided with an inclined surface.

[0012] Preferably, the inner ring surface of the outer ring groove is provided with an external thread, and the inner wall of the limiting cover is provided with an internal thread. After the limiting cover is sleeved on the outer ring groove, the internal thread and the external thread are in fit connection.

[0013] Preferably, a rubber pad is fixed at one end of the limiting cover. The rubber pad is clamped between the limiting cover and the outer ring groove to generate elastic deformation. A reserved groove is provided on the inner wall at the other end of the limiting cover. The reserved groove is an annular groove. The end of the hand-tightening screw extends into the reserved groove.

[0014] Preferably, a plurality of mounting strips are fixed on the surface of the limiting cover. The mounting strips are in the shape of a "C"-shaped plate structure. A handle is inserted into the mounting strips. A limiting shaft is fixed between two parallel side plates of the mounting strips. The limiting shaft penetrates through one end of the handle.

[0015] Preferably, missing grooves are provided on both sides at the other end of the handle. Rubber clamping strips are fixed on the surface of the missing grooves. The rubber clamping strips are clamped between the handle and the side plates of the mounting strips to generate elastic deformation.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The tool-free disassembly and cleaning structure for the front grille of a cooling fan proposed in this invention achieves tool-free disassembly and installation of the grille frame and grille plate through ingenious structural design. To remove the grille frame, simply pull the retaining cover out of the outer ring groove; the rubber ring will spring back, pulling the clamping handle back to its original position. The end of the clamping handle will then be pulled out of the slot, allowing the grille frame to be removed from the mounting groove. For installation, push the grille frame into the mounting groove, then slip the retaining cover on and push the clamping handle into the slot to complete the installation. The entire process requires no additional tools such as screwdrivers, making it simple and convenient to operate, greatly saving disassembly and cleaning time and improving maintenance efficiency.

[0017] A rubber ring is fixed to the outer ring surface of the mounting groove inside the mounting cover. When the mesh cover frame is inserted into the mounting groove, the rubber ring is clamped between the mounting groove and the outer ring surface of the mesh cover frame, generating elastic deformation, effectively preventing the mesh cover frame from falling out of the mounting groove. At the same time, the limiting cover pushes the clamping handle to stretch the rubber ring and inserts it into the slot on the outer ring surface of the mesh cover frame, further enhancing the connection stability between the mesh cover frame and the mounting cover. This ensures that the mesh cover frame will not loosen due to vibration or other reasons during fan operation, guaranteeing the normal operation and safe use of the cooling fan.

[0018] A mesh panel and a clamping plate are inserted into the mounting groove at the inner ring of the mesh cover frame. A hand-tightened screw passes through the clamping plate and mesh panel and is then screwed onto the surface of the mounting groove, firmly fixing the mesh panel inside the mesh cover frame. Furthermore, washers are pre-installed on the hand-tightened screw during installation to ensure it does not fall off after installation, further improving the reliability of the mesh panel's fixation and preventing it from loosening or falling off during use.

[0019] The inner surface of the outer ring groove has external threads, and the inner wall of the limiting cover has internal threads. The connection between these threads achieves initial fixation between the limiting cover and the outer ring groove. Simultaneously, a rubber pad fixed at one end of the limiting cover clamps between the limiting cover and the outer ring groove, generating elastic deformation and further enhancing the stability of the limiting cover. Furthermore, a pre-drilled groove on the inner wall of the other end of the limiting cover allows the end of a hand-tightening screw to be inserted, thus limiting the position of the limiting cover. This multi-layered anti-detachment design ensures that the limiting cover will not accidentally fall off during use, guaranteeing the stability of the entire front mesh cover structure.

[0022] To make the objectives, technical solutions, and advantages of the present invention clear and complete, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Please see Figures 1-6 This invention provides a technical solution: a tool-free, removable and cleanable cooling fan front mesh cover structure, including a mounting cover 1. A mesh cover frame 2 is inserted into the inner ring of the mounting cover 1. A mesh plate 203 is installed in the inner ring of the mesh cover frame 2. The mounting cover 1 is an L-shaped circular plate. Multiple pre-drilled holes 101 are provided on the surface of the mounting cover 1. An insert groove 102 is provided in the inner ring of the mounting cover 1. A rubber ring 4 is fixed to the outer ring surface of the insert groove 102. The mesh cover frame 2 is inserted into the insert groove 102. 4. The mesh plate 203 is inserted into the mounting groove 202 and the outer ring surface of the mesh frame 2, and a clamping plate 204 is inserted into the mounting groove 202. The clamping plate 204 is annular and the inner ring diameter of the clamping plate 204 is equal to the inner ring diameter of the mesh frame 2. A hand screw 205 is screwed onto the surface of the clamping plate 204. The hand screw 205 passes through the clamping plate 204 and the mesh plate 203 and is screwed onto the surface of the mounting groove 202.

[0024] First, push the mesh plate 203 into the mounting groove 202, then insert the rubber ring 4 into the mounting groove 202, and fix the clamping plate 204 and the mesh plate 203 in the mounting groove 202 by hand-tightening the screw 205. It should be noted that a gasket is pre-installed on the hand-tightening screw 205 during installation to ensure that the hand-tightening screw 205 does not fall off after installation. Then, put the mounting cover 1 on the front end of the fan, and fix the mounting cover 1 to the front end of the fan by bolting through the reserved hole 101 and the hole on the surface of the fan housing.

[0025] In order to achieve tool-free disassembly of the mesh cover frame 2, the following is proposed: An outer ring groove 103 is provided on the outer ring surface of the installation cover 1. A plurality of clamping handles 3 are inserted on the surface of the outer ring groove 103. The clamping handles 3 penetrate through the installation cover 1 and are inserted into the outer ring surface of the mesh cover frame 2. A limiting cover 5 is sleeved in the outer ring groove 103, and the limiting cover 5 blocks the backward movement of the clamping handle 3; a clamping groove 201 is provided on the outer ring surface of the mesh cover frame 2. The clamping groove 201 is an annular groove. The limiting cover 5 pushes the clamping handle 3 to stretch the rubber ring 4 and then inserts it into the clamping groove 201; a plurality of jacks 104 are provided on the inner ring surface of the outer ring groove 103. The clamping handles 3 and the jacks 104 correspond to each other one by one. The clamping handles 3 are inserted into the jacks 104, and the height of the clamping handle 3 is greater than the depth of the jack 104. One end of the clamping handle 3 is fixed on the outer ring surface of the rubber ring 4, and the other end of the clamping handle 3 is provided with an inclined surface.

[0026] When installing the mesh cover frame 2, only need to push the mesh cover frame 2 into the embedded groove 102. At this time, the rubber ring 4 is clamped between the mesh cover frame 2 and the embedded groove 102 to prevent the mesh cover frame 2 from falling off the embedded groove 102. And at this time, one end of the clamping handle 3 extends out of the jack 104. The limiting cover 5 is sleeved and pushed into the outer ring groove 103. The limiting cover 5 pushes the clamping handle 3 along the inclined surface. After the clamping handle 3 is pressed, it retracts into the jack 104, and the other end of the clamping handle 3 stretches the rubber ring 4 and then inserts it into the clamping groove 201; when the mesh cover frame 2 needs to be removed, the limiting cover 5 is pulled out from the outer ring groove 103. The rubber ring 4 rebounds and pulls the clamping handle 3 to reset. The end of the clamping handle 3 is pulled out from the clamping groove 201. At this time, the mesh cover frame 2 can be pulled out from the embedded groove 102.

[0027] In order to achieve anti-detachment of the limiting cover 5 after being sleeved in the outer ring groove 103, the following is proposed: The inner ring surface of the outer ring groove 103 is provided with an external thread, and the inner wall of the limiting cover 5 is provided with an internal thread. After the limiting cover 5 is sleeved in the outer ring groove 103, the internal thread and the external thread are connected in cooperation; a rubber pad 502 is fixed at one end of the limiting cover 5. The rubber pad 502 is clamped between the limiting cover 5 and the outer ring groove 103 and generates elastic deformation. A reserved groove 501 is provided on the inner wall at the other end of the limiting cover 5. The reserved groove 501 is an annular groove. The end of the hand-twisting screw rod 205 extends into the reserved groove 501; a plurality of mounting strips 6 are fixed on the surface of the limiting cover 5. The mounting strips 6 are in a "U" - shaped plate structure. A handle 602 is inserted into the mounting strip 6. A limiting shaft 601 is fixed between two parallel side plates of the mounting strip 6. The limiting shaft 601 penetrates through one end of the handle 602; slots 603 are provided on both sides at the other end of the handle 602. Rubber clamping strips 604 are fixed on the surface of the slots 603. The rubber clamping strips 604 are clamped between the handle 602 and the side plates of the mounting strip 6 and generate elastic deformation. After the handle 602 is rotated 180 degrees around the limiting shaft 601, hold the handle 602 and turn the limiting cover 5. In this way, it is more labor-saving to turn the limiting cover 5.

[0028] The specific instructions for using the tool-free, removable and cleanable cooling fan front grille are as follows: The installation cover 1 is sleeved on the front end of the fan. After bolts pass through the reserved holes 101 opened on the surface of the installation cover 1 and the holes on the surface of the fan housing, the installation cover 1 is fixed to the front end of the fan. At this time, the installation cover 1 is a circular ring plate with a cross-section of "L", providing a basic support for the installation of other components in the follow-up. The mesh plate 203 is pre-pushed into the installation groove 202 opened at the inner ring opening of the mesh cover frame 2. The clamping plate 204 is inserted into the installation groove 202. The clamping plate 204 is a circular ring plate, and its inner ring diameter is equal to the inner ring diameter of the mesh cover frame 2. When installing the hand-tightening screwAt this time, the rubber ring 4 rebounds and pulls the clamping handle 3 to reset. The end of the clamping handle 3 is pulled out from the slot 201, and then the mesh frame 2 can be pulled out from the mounting slot 102 to complete the removal of the mesh frame 2.
