Description

Technical Field

[0001] This utility model relates to the technical field of electric fan accessories, and specifically to a front and rear shared mesh cover. Background Technology

[0002] A wire mesh cover is a protective device made of metal wire that is fixed to the front end of electrical appliances or metal parts. It is mainly used to prevent the human body from coming into contact with high temperatures, rotating parts or sharp edges. Its applications cover industrial ventilation equipment, new energy equipment and loudspeakers.

[0003] Most fan guards on the market consist of a front guard, a rear guard, and a connecting decorative ring. The front and rear guards are fixed together by connecting buckles on the guards, and a connecting decorative ring secures the two guards together, with screws and nuts at both ends. For example, Chinese utility model patent application CN 203453134 U discloses a fan guard assembly and a fan having the same, comprising: a first guard with a first connecting portion on its periphery; a second guard with a second connecting portion on its periphery, the second connecting portion cooperating with the first connecting portion to connect the second guard to the first guard; and a decorative ring with a groove formed on its inner peripheral wall, the connecting portion of the first and second guards located within the groove. This fan guard assembly, by providing connecting parts on the first and second guards respectively, allows for pre-assembly of the first and second guards before assembling the decorative ring, facilitating the assembly of the decorative ring.

[0004] However, the existing fan guard assembly and the fan with it require aligning the two guards before installation, and then tightening them at the alignment point with a connecting decorative ring. This installation and adjustment method is very inconvenient. In addition, the front and rear guards have different shapes, requiring two different sets of molds for production, which increases costs and is not conducive to production management. Furthermore, they are difficult to stack and store, often taking up more space when packaged, which is not conducive to transportation management. Utility Model Content

[0024] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0025] See Figures 1 to 6 As shown, a front and rear shared mesh cover includes two mesh covers 100. The two mesh covers 100 are identical in shape, structure and size. Each mesh cover 100 is provided with a first limiting structure and a second limiting structure evenly distributed around its circumference. After the two mesh covers 100 are joined face to face, the first limiting structure of one mesh cover 100 is joined with the second limiting structure of the other mesh cover 100 to achieve positioning, and is locked by buckles or screws, so that the two mesh covers 100 are detachably fixed.

[0026] This invention changes the traditional installation method that requires connecting decorative rings. Instead, it utilizes the docking of the first limiting structure of one mesh cover 100 with the second limiting structure of the other mesh cover 100 for positioning, and locks them together with snaps or screws, making the two mesh covers 100 detachable and fixed. This eliminates the need for decorative rings, effectively optimizing the overall structure and improving the convenience of installation and adjustment, making it suitable for widespread application to various electric fan mesh cover structures. Furthermore, compared to existing structures, the two mesh covers 100 in this invention have identical shapes, structures, and dimensions, allowing for manufacturing using the same tools without the need for two sets of molds, effectively saving production costs. They also allow for stacking and storage, greatly reducing the space required for transportation, facilitating repackaging, saving transportation costs, and simplifying transportation management.

[0027] The two mesh covers 100 are a first mesh cover 1 and a second mesh cover 2, respectively. The first limiting structure is divided into a first locking tooth portion 11 disposed on the first mesh cover 1 and a second locking tooth portion 21 disposed on the second mesh cover 2. The second limiting structure is divided into a first locking groove portion 12 disposed on the first mesh cover 1 and a second locking groove portion 22 disposed on the second mesh cover 2. The first limiting structure and the second limiting structure are staggered so that the first mesh cover 1 and the second mesh cover 2 can be connected face to face.

[0028] It also includes a cover 3, which is disposed on the first mesh cover 1 / second mesh cover 2; the outer edge of the first mesh cover 1 is formed with a first annular protrusion 101, and a first locking tooth portion 11 and a first locking groove portion 12 are both distributed on the first protrusion 101; the outer edge of the second mesh cover 2 is formed with a second annular protrusion 201, and a second locking tooth portion 21 and a second locking groove portion 22 are both distributed on the second protrusion 201; the first mesh cover 1 and the second mesh cover 2 are both integrally injection molded from plastic material. Here, the first protrusion 101 can enhance the overall strength of the first mesh cover 1, and the second protrusion 201 can enhance the overall strength of the second mesh cover 2, so as to ensure that the first locking tooth portion 11 and the second locking groove portion 22 cooperate, and the second locking tooth portion 21 and the first locking groove portion 12 can remain stable and undeformed after cooperation, effectively improving product quality.

[0029] The first mesh cover 1 has a first through hole 102 in its center; the second mesh cover 2 has a second through hole 202 in its center; the cover 3 is disc-shaped and covers the first through hole 102 / second through hole 202. The cover 3 has several protruding fastening teeth 31 for engaging with the first mesh cover 1 / second mesh cover 2; a first fastening groove 103 for engaging the fastening teeth 31 is formed around the first through hole 102; a second fastening groove 203 for engaging the fastening teeth 31 is formed around the second through hole 202. Here, the first through hole 102 / second through hole 202 are for the output shaft of an external fan motor to pass through. When the second mesh cover 2 is used as the rear cover (i.e., the side closest to the fan motor) and the first mesh cover 1 is used as the front cover, the fan motor output shaft will pass through the second through hole 202, while the first through hole 102 of the first mesh cover 1 will be exposed in front, which is neither aesthetically pleasing nor safe. Therefore, a cover 3 is used to cover the first through hole 102, which can prevent fingers from being caught, effectively improving safety and greatly enhancing aesthetics. The same principle applies when the second mesh cover 2 is used as the front cover and the first mesh cover 1 is used as the rear cover; these will not be elaborated further here.

[0030] The first locking teeth 11 are three in number and arranged in a triangular pattern on the first boss 101. Each first locking tooth 11 includes a first overlapping edge 111 protruding from the first boss 101, a first locking tooth 112 protruding from the first overlapping edge 111 for engaging with the first locking groove 12, a first rib 113 disposed on the first overlapping edge 111, and a first through hole 114 disposed on the first boss 101. Here, the first mesh cover 1 and the second mesh cover 2 in this utility model can also be connected and fixed by screws. Specifically, a first screw 71 is inserted into the first through hole 114, and the first screw 71 passes through the first through hole 114 and is installed in the second screw hole 223 to fasten the first mesh cover 1 and the second mesh cover 2.

[0031] The second locking teeth 21 are three in number and arranged in a triangular pattern on the second boss 201. Each second locking tooth 21 includes a second overlapping edge 211 protruding from the second boss 201, a second locking tooth 212 protruding from the second overlapping edge 211 for engaging with the second locking groove 22, a second protruding rib 213 provided on the second overlapping edge 211, and a second through hole 214 provided on the second boss 201. Here, the first mesh cover 1 and the second mesh cover 2 in this utility model can also be connected and fixed by screws. Specifically, a second screw 72 is inserted into the second through hole 214. The second screw 72 passes through the second through hole 214 and is installed in the first screw hole 123. The first screw 71 and the second screw 72 are oriented opposite each other, which can better secure the first mesh cover 1 and the second mesh cover 2.

[0032] The first slot portion 12 comprises three parts arranged in a triangular pattern on the first boss 101. Each first slot portion 12 includes a first protruding edge 121 protruding from the first boss 101, a first latch 122 disposed on the first protruding edge 121 for engaging with the second protruding rib 213, a first screw hole 123 disposed on the first boss 101 and matching the second through hole 214, and a first slot 124 disposed on the first protruding edge 121 for engaging with the second latching teeth 212. Here, the second protruding rib 213 engages with the first latching edge 122 to circumferentially limit the second mesh cover 2, and the second latching teeth 212 engage with the first slot 124 to prevent the second mesh cover 2 from detaching from the first mesh cover 1.

[0033] The second slot portion 22 comprises three parts arranged in a triangular pattern on the second boss 201. Each second slot portion 22 includes a second protruding edge 221 protruding from the second boss 201, a second latch 222 disposed on the second protruding edge 221 for engaging with the first protruding rib 113, a second screw hole 223 disposed on the second boss 201 and matching the first through hole 114, and a second slot 224 disposed on the second protruding edge 221 for engaging with the first latching tooth 112. Here, the first protruding rib 113 engages with the second latch 222 to circumferentially limit the first mesh cover 1, preventing accidental slippage during use. Simultaneously, the first latching tooth 112 engages with the second slot 224 to prevent the first mesh cover 1 from detaching from the second mesh cover 1.

[0034] Since it is necessary to achieve both stackable storage between the first mesh cover 1 and the second mesh cover 2 and detachable connection between them, this utility model adopts a tooth-slot connection method. During installation, simply align the first tooth 112 with the second slot 224 and the second tooth 212 with the first slot 124, and then press them together. This eliminates the need for decorative rings, improves the convenience of installation and adjustment, and also enables stackable storage, greatly reducing the space occupied during transportation.

[0035] The first mesh cover 1 is provided with a first mesh area 107 arranged in a ring; the second mesh cover 2 is provided with a second mesh area 108 arranged in a ring; multiple first support bars 91 are provided between the first boss 101 and the first mesh area 107, and a first gap 93 is formed between two adjacent first support bars 91; a second support bar 92 is provided between the second boss 201 and the second mesh area 108, and a second gap 94 is formed between two adjacent second support bars 92.

[0036] In one embodiment of this utility model, combined with Figure 5 and Figure 6 As shown, when the first mesh cover 1 is stacked on top of the second mesh cover 2, the first support strip 91 is housed in the second gap 94, and the second support strip 92 is housed in the first gap 93. Here, both the first support strip 91 and the second support strip 92 are L-shaped or inverted L-shaped, and the first support strip 91 and the second support strip 92 are staggered to allow the first mesh cover 1 and the second mesh cover 2 to overlap more deeply and achieve a better overlapping effect.

[0037] In another embodiment of this utility model, the first mesh cover 1 and the second mesh cover 2 can also be stacked without misalignment between the first support bar 91 and the second support bar 92. For example, the shape of both the first support bar 91 and the second support bar 92 can be set as an inclined straight line, so that they can be stacked without misalignment between the first support bar 91 and the second support bar 92.

[0038] In summary, this invention changes the traditional installation method that requires connecting decorative rings. It utilizes the docking of the first limiting structure of one mesh cover 100 with the second limiting structure of the other mesh cover 100 to achieve positioning, and locks them together with buckles or screws, making the two mesh covers 100 detachable and fixed. This eliminates the need for decorative rings, effectively optimizes the overall structure, and improves the convenience of installation and adjustment, making it suitable for widespread application to various electric fan mesh cover structures. Furthermore, compared with existing structures, in this invention, the two mesh covers 100 are identical in shape, structure, and size, allowing for manufacturing using the same tool without the need for two sets of molds, effectively saving production costs. Moreover, it allows for stacking and storage, greatly reducing the space required for transportation, facilitating repackaging, saving transportation costs, and simplifying transportation management.

[0039] Of course, the above description is only a specific embodiment of the present utility model and is not intended to limit the scope of the present utility model. All equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model should be included in the scope of the claims of the present utility model.
