Abstract
Description
Technical Field
[0001] This utility model relates to the field of air conditioning louvers, and in particular to a louver frame structure with an adjustable angle. Background Technology
[0002] Currently, the louvered air outlets of commercial air conditioning units on the market consist of a sheet metal frame, rubber plugs, and flocked louvers. The louvers rotate using the friction of the rubber plugs on the rotating shaft, thus adjusting the angle. However, in large units, due to the large air volume, the friction of the rubber plugs on both sides of the louvers is insufficient to keep them stationary. After the unit has been running for a period of time, the louvers will be blown closed by the airflow, reducing the air outlet area, increasing the motor load, and potentially causing motor damage.
[0003] Because it cannot maintain the angle specified by the customer, the function of setting the air outlet angle for the louvered frame is also lost.
[0004] For example, Chinese patent 202421341108.2 mainly uses gears to achieve the limiting position. Utility Model Content
[0005] The main purpose of this invention is to propose an adjustable-angle louver frame structure, which aims to improve the existing louver structure and achieve stable positioning of the swaying wall louver strips.
[0006] To achieve the above objectives, this utility model proposes an adjustable-angle louver frame structure, comprising a frame, rubber plugs, louver strips, a limiting plate, and a spring. The two ends of the louvered strip are pivotally mounted between the frames via a pivot shaft, and the pivot shaft is fitted with a rubber plug, which is damped by the pivot hole. The limiting plate is located on the rear wall of the frame, and the limiting plate has one... The wall surface of the limiting plate is provided with multiple grooves distributed along the height direction, and the shape of the grooves is adapted to the swing direction of the louvers. The groove is provided with a protruding locking part, which extends out of the wall of the groove and abuts against the end of the louver strip.
[0007] Under normal use, the louvered slats will be stuck in the groove of the limiting plate and cannot move. When you need to adjust the angle, simply bend the louvers by hand. Because the limiting plate and the frame are connected by a spring, the limiting plate will move backward. When adjusted to the desired position, release your hand. The limit plate will return to its original position under the pull of the spring, locking the louver strip to prevent movement, thus realizing the function of adjustable louver angle.

[0010] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0011] It should be noted that if any directional indication (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial, etc.) is involved in the embodiments of this utility model, the directional indication is only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.
[0012] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," such descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.
[0013] like Figures 1 to 2 As shown, an adjustable-angle louver frame structure includes a frame 1, a rubber plug 2, louver strips 3, a limiting plate 4, and a spring 5. The two ends of the louvered strip 3 are pivotally mounted between the frames 1 via a pivot 20. The pivot 20 is fitted with a rubber plug 2, and the rubber plug 2 is dampedly connected to the pivot hole 21. The limiting plate 4 is located on the rear wall of the frame 1, and the limiting plate 4 has one... The wall surface of the limiting plate 4 is provided with multiple grooves distributed along the height direction, and the shape of the grooves is adapted to the swing direction of the louver slats 3. The groove is provided with a protruding locking part, which extends out of the wall of the groove and abuts against the end of the louver strip 3.
[0014] Under normal use, the louvered strip 3 will be stuck in the groove of the limiting plate 4 and cannot move; When the angle needs to be adjusted, manually bend the louver slats 3. Since the limiting plate 4 and the frame 1 are connected by a spring 5, the limiting plate 4 will move backward. When adjusted to the desired position, release your hand. The limit plate will return to its original position under the pull of spring 5, locking the louver strip 3 to prevent movement, thereby realizing the function of adjustable louver angle.
[0015] Specifically, the limiting plate is made of an elastic material, which is rubber.
[0016] Specifically, different materials can be used according to actual needs to achieve the damping and locking limiting effects.
[0017] In this embodiment of the utility model, the limiting plate is made of a metal material with deformability, that is, the limiting is achieved by elastic resistance.
[0018] Specifically, the groove is provided with a plurality of spaced protrusions or frosted layers. When it is a frosted layer, the louvered strip 3 can increase the contact area and improve the engagement stability.
[0019] In this embodiment of the invention, the end face of the louvered strip 3 that abuts against the wall of the groove is wedge-shaped.
[0020] In this embodiment of the invention, the bumps and recesses are distributed in a tooth-like pattern.
[0021] Specifically, a tension spring is provided between the frame 1 and the limiting plate. The first end 51 of the tension spring is connected to the frame 1. The second end 52 of the tension spring is connected to the limiting plate. The tension spring is used to apply a spring force to the limiting plate to slide in the direction of the louver slat 3, thereby realizing the limiting plate's limitation on the louver slat 3.
[0022] In this embodiment of the utility model, the limiting plate is located in the middle of the frame 1. The middle location can improve the support of the louver strip 3 and the deformation of the wall caused by wind, and can also improve the limiting function.
[0023] Specifically, the limiting plate is provided in three parts and is symmetrically arranged with the middle limiting plate as the base point to improve the overall support of the frame 1.
[0024] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
