Description

Technical Field

[0001] The utility model relates to the technical field of seat fans, and particularly relates to an improved assembly structure between the housing and the fan blade of a seat fan. Background Art

[0002] Currently, the assembly between the housing and the fan blade of a seat fan usually adopts the glue rubbing method. However, this traditional method has exposed many problems in practical applications, not only affecting production efficiency, but also posing challenges to the stability of product quality.

[0003] First of all, the glue rubbing and fixing method significantly increases the production time cost. After applying glue between the fan blade and the housing, it is necessary to wait for the glue to dry completely to achieve the desired fixing effect. This waiting process will undoubtedly greatly reduce the operating efficiency of the entire production line. For modern enterprises pursuing high-efficiency production, this is undoubtedly a huge bottleneck.

[0004] Secondly, the introduction of the glue rubbing process makes the design of the automated production line more complex. In today's increasingly automated era, any additional process may increase the complexity and maintenance cost of the production line.

[0005] In addition, the glue rubbing and fixing method cannot guarantee the stability of the bonding force. If the amount of glue rubbed is not properly controlled, it will lead to uneven bonding forces, which will not only affect the performance of the product, but may also cause potential safety hazards during use.

[0006] Finally, the glue itself also has the problem of aging and failure. Over time, the glue may gradually lose its viscosity, resulting in the failure of the fixation between the fan blade and the housing, and then causing equipment failures. This not only increases the maintenance cost, but may also cause troubles to the normal use of users. Content of the Utility Model

[0007] The technical problem to be solved by the utility model is to provide an improved assembly structure between the housing and the fan blade of a seat fan in view of the above deficiencies existing in the existing assembly of seat fans and fan blades using the glue rubbing and fixing method. It realizes the fixation of the two through the reverse buckle connection between the housing and the fan blade, and at the same time cleverly avoids the cumbersome glue rubbing process.

[0008] The technical problem to be solved by the utility model can be achieved through the following technical solutions:

[0009] An improved assembly structure between a seat fan casing and blades comprises blades and a casing, wherein a casing mounting hole is arranged at the center of the blades, and the casing is cylindrical, characterized in that at least one inverted buckle socket is arranged on the flange edge of the casing mounting hole; at least one inverted buckle is arranged on the end surface of one end of a casing arm of the casing; during assembly, the casing is inserted into the casing mounting hole, and the inverted buckle is inserted into the inverted buckle socket.

[0010] In a preferred embodiment of the utility model, the undercut sockets are multiple and circumferentially arranged on the flange of the housing mounting hole; the undercut sockets are circumferentially arranged on the end surface of one end of the housing arm of the housing.

[0011] In a preferred embodiment of the present invention, a barb is respectively arranged on both sides of the free end of each undercut.

[0012] Due to the adoption of the above technical solution, the utility model adds an inverted buckle on the casing and an inverted buckle socket on the fan blade, and the two are matched to ensure that they can be accurately, quickly and perfectly connected together during assembly, thereby improving production efficiency and ensuring the stability and reliability of the connection, so that the fan blade can be firmly fixed to the casing and is not easy to loosen or fall off, thereby ensuring the stability and safety of the entire seat fan.

[0013] The utility model saves the traditional glue wiping process, simplifies the production process and reduces the cost. BRIEF DESCRIPTION OF THE DRAWINGS
