TECHNICAL FIELD
[0001] The utility model relates to wall fan mounting device technical field, especially a quick release type wall fan mounting device with enhanced pitch adjustment function. BACKGROUND
[0002] The existing wall fan usually realizes the pitch adjustment of the fan head through the pivoting mechanism, but there are still many problems to be solved in actual application. First, the pitch adjustment range is limited. Since the structure of the supporting rod limits the activity space of the fan head when the fan head is pitch adjusted in the traditional wall fan, the fan head is easy to collide with the supporting rod when the pitch angle is large, resulting in insufficient pitch range and unable to meet the needs of multi-angle wind direction adjustment of the user. Secondly, the fixed stability of the pitch angle is poor. After adjusting the angle, the existing wall fan lacks a reliable fixing structure, so that the angle is easy to loosen or deviate during use, and cannot maintain a stable working state for a long time. In addition, the pitch adjustment structure of part of the wall fan is designed to be relatively complex, and the operation is not convenient. The user needs to exert a large force when adjusting the angle, and at the same time, the limit protection device for pitch adjustment is not set, which may cause safety hazards due to too large angle. For example, the patent CN202221392933.6 solves the limitation of the supporting rod end on the pitch adjustment by setting a rod avoidance groove in the fan head motor shell, which can expand the angle range of the pitch adjustment, but the scheme only realizes the basic avoidance function of the rod avoidance groove, and cannot effectively solve the problem of insufficient fixed stability of the pitch angle, and also does not set the limit protection design of the pitch adjustment range. In addition, the structure design of the rod avoidance groove and the supporting rod still has optimization space, and the adjustment may not be smooth enough. Therefore, the existing technology urgently needs an improved wall fan mounting device, which optimizes the pitch adjustment structure and function design, provides multi-positioning and limit protection mechanism on the basis of expanding the adjustment range, and improves the convenience and safety of the adjustment operation to meet the wind direction adjustment needs of the user in multiple scenes.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Please refer to Figures 1 to 5, which illustrate a technical solution provided by this utility model:
[0029] A quick-release wall fan mounting device with enhanced pitch adjustment function includes: a support base plate, fixed to the wall, for providing overall support for the device;
[0030] The support rod is fixed at one end to the support base plate, and at the other end is pivotally connected to the fan head via a pivoting mechanism;
[0031] The fan head consists of a motor housing, a fan mesh, and fan blades. The motor housing is provided with a recessed rod avoidance groove, which allows the end of the support rod to pass through the rod avoidance groove during pitch adjustment.
[0032] The pivoting mechanism includes a positioning plate and elastic beads. The surface of the positioning plate is provided with a plurality of arc-shaped positioning holes arranged around the pivot point (A). The elastic beads include a spring and a retaining ball for fixing the pitch angle of the fan head to the positioning holes.
[0033] Example 1: Structure design and assembly of the overall device
[0034] As shown in FIG. 1 and FIG. 2, the device includes a support base plate (1), a support rod (2), a pivot mechanism (3), and a fan head (4). The support base plate (1) is fixed to the wall surface by bolts or expansion screws to provide stable support for the overall device. One end of the support rod (2) is fixedly connected to the support base plate (1), and the other end is pivotally connected to the fan head (4) through the pivot mechanism (3).
[0035] The fan head (4) is composed of a motor housing (41), a fan net (42), and a fan blade (43) inside the fan net (42). The motor housing (41) is designed with an inner recessed rod avoidance groove (44) located at the top of the motor housing (41) and corresponding to the position of the support rod (2), which can effectively avoid the limitation of the end of the support rod (2) on the pitch adjustment and improve the pitch angle range. The ends of the rod avoidance groove (44) are provided with limit end walls (45) and blocking strip end walls (46), which provide physical limitations when the fan head (4) is adjusted to the pitch limit position, ensuring the safety of angle adjustment.
[0036] Example 2: Multi-step positioning structure of pitch angle
[0037] As shown in FIG. 3 and Figure 4 To improve the stability and accuracy after pitch adjustment, the pivot mechanism (3) is designed with a multi-step positioning device. The positioning device includes a positioning plate (31) and an elastic bead (33). The positioning plate (31) is fixed vertically at the end of the support rod (2), and its surface is distributed with multiple positioning holes (32) arranged in an arc around the pivot point (A). The elastic bead (33) is installed on the side wall inside the rod avoidance groove (44) and is composed of a spring (34) and a bead (35), with the spring (34) pushing the bead (35) to insert into the positioning hole (32). During the pitch adjustment, the bead (35) can be slid into different positioning holes (32) to achieve multi-step positioning and ensure the stability of the fan head after adjustment.
[0038] Example 3: Pitch adjustment range and safety protection
[0039] As shown in FIG. 5, the avoidance rod groove (44) adopts a through concave design, which precisely matches the outer diameter of the end of the support rod (2), making the pitch adjustment process more smooth. When the user operates the fan head (4) for pitch adjustment, the limiting end wall (45) and the blocking end wall (46) at both ends of the avoidance rod groove (44) will provide physical blocking at the limit angle, avoiding safety risks caused by excessive adjustment. This design not only ensures the safety of the adjustment range, but also enhances the durability of the device. When the user adjusts the pitch angle of the fan head, the clamping beads (35) slide and position between the positioning holes (32), forming multiple angle options; when the fan head (4) continues to adjust to the pitch limit position, the limiting end wall (45) at the end of the avoidance rod groove (44) abuts against the end of the support rod (2), preventing overtravel and rebound, thereby ensuring the stable maintenance of the pitch angle. This design forms a synergistic effect between the positioning holes, elastic beads and limiting end walls, improving the reliability and safety of pitch adjustment.
[0040] Example 4: Material optimization and structural enhancement
[0041] As shown in FIG. 2 and Figure 4 The positioning plate (31) and the positioning hole (32) are made of wear-resistant metal materials, which can withstand long-term adjustment and mechanical friction, prolonging the service life of the device. The spring (34) in the elastic bead (33) is made of high-strength spring material, ensuring that it can still provide stable thrust after long-term use, avoiding angle loosening or positioning failure. In addition, the concave part of the avoidance rod groove (44) is treated with a smooth coating to reduce friction resistance, further improving the smoothness of pitch adjustment.
[0042] Example 5: Installation adjustment to meet multi-angle requirements
[0043] The installation direction of the support base plate (1) can be adjusted according to the actual situation of the wall surface, and the support rod (2) and the support base plate (1) are connected through pre-set bolt holes for multi-directional installation, adapting to various use environments. The avoidance rod groove (44) can adjust the concave shape and opening direction according to the special needs of the installation environment. For example, in industrial environments, the opening angle of the avoidance rod groove (44) can be increased to meet special ventilation needs
[0044] Example 6: User-friendly operation design
[0045] The elastic bead (33) is designed with a detachable structure for easy maintenance, and the user only needs to loosen the fixing bolts to easily replace the spring (34) or clamping bead (35). In addition, the
[0046] number and distribution angle of the positioning holes (32) can be customized according to user needs, such as adding smaller interval positioning holes to meet more precise pitch angle adjustment.
[0047] The basic principle, main features and advantages of the present application are shown and described above
