Abstract
Description
Technical Field
[0001] This utility model relates to the field of industrial fans, and in particular to an industrial fan that is easy to manufacture. Background Technology
[0002] In the field of industrial fans, the structural design of the mesh cover directly affects the mold cost and assembly efficiency of the fan. Traditional industrial fans usually adopt a one-piece molded front and rear mesh cover structure, that is, the front and rear mesh covers are manufactured by a one-piece mold. This design often requires a large-sized mold to accommodate the overall molding of the mesh cover, which increases the cost of the mold and the manufacturing difficulty. In addition, the front and rear mesh covers usually need to be fixed together with additional connecting parts (such as mesh cover connecting rings) to form a complete protective cover. This makes it necessary to manufacture the mesh cover and mesh cover connecting ring separately with multiple molds, which increases the manufacturing cost and the assembly time and difficulty of the whole machine. Utility Model Content
[0003] The technical problem to be solved by this utility model is to provide an industrial fan that is easy to produce, which can reduce the size and number of molds and simplify the assembly process.
[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an industrial fan that is easy to produce, including a base, a fan blade assembly and a protective cover assembly. The base is used to support the protective cover assembly. The fan blade assembly is installed inside the protective cover assembly. The protective cover assembly includes multiple mesh blocks. At least two of the mesh blocks are spliced together to form a circular front mesh cover or a rear mesh cover. The front mesh cover and the rear mesh cover are spliced and fixed.
[0005] Furthermore, the straight edge of the mesh cover block is provided with multiple mating through holes, and the mesh cover block is fixedly spliced through the mating through holes to form the front mesh cover or the rear mesh cover. The arc-shaped edge of the mesh cover block is provided with multiple fixing holes, and the front mesh cover and the rear mesh cover are fixedly spliced through the fixing holes.
[0006] Furthermore, the shape of the mesh block is semi-circular or fan-shaped.
[0007] Furthermore, the front and rear mesh covers have the same shape.
[0008] Furthermore, the lower end of the base is equipped with casters for easy movement.
[0009] Compared with the existing technology, the advantages of this utility model are that the original one-piece mesh cover is designed as multiple mesh cover blocks, which can effectively reduce the size of the mold, reduce the manufacturing difficulty and cost. In addition, multiple mesh cover blocks are combined to form a complete protective cover, which does not require mesh cover connecting rings for connection, which can reduce the number of molds and make product assembly simpler. Attached Figure Description
[0010] Figure 1 This is a three-dimensional structural diagram of the present invention;
[0011] Figure 2 This is an exploded view of the three-dimensional structure of this utility model;
[0012] Figure 3 This is a schematic diagram of the structure of the front or rear mesh cover of this utility model. Detailed Implementation
[0013] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.
[0014] like Figure 1-3 As shown, an industrial fan that is easy to manufacture includes a base 1, a fan blade assembly 2, and a protective cover assembly 3. Casters 4 are fixedly connected to the lower end of the base 1 for easy movement. The base 1 supports the protective cover assembly 3. The fan blade assembly 2 is installed inside the protective cover assembly 3. The protective cover assembly 3 includes multiple mesh blocks 33, each with a semi-circular shape. Multiple fixing holes 34 are spaced along the arc-shaped edges of the mesh blocks 33, and multiple mating through holes 35 are provided along the straight edges of the mesh blocks 33. Two identical mesh blocks 33 are spliced and fixed together through the mating through holes 35 on their straight edges to form a circular front mesh cover 31 or rear mesh cover 32. The spliced front mesh cover 31 and rear mesh cover 32 have the same shape and are fixed together through the fixing holes 34. This design requires only one small mold to complete the production of the protective cover assembly 3, effectively reducing the mold volume and quantity, and lowering production costs. The connections between the mesh blocks 33 are all made of screws, which facilitates assembly.
[0015] In addition to the structure shown in the attached figure, the shape of the mesh block 33 can also be fan-shaped, and multiple fan-shaped mesh blocks 33 can be spliced and fixed to form a complete protective cover.
[0016] The scope of protection of this utility model includes, but is not limited to, the above embodiments. The scope of protection of this utility model is defined by the claims. Any substitutions, modifications, or improvements to this technology that are easily conceived by those skilled in the art shall fall within the scope of protection of this utility model.
