Description

Technical Field

[0001] This utility model relates to the field of sunshade technology, specifically to a blade base and a louvered sunshade using the blade base. Background Technology

[0002] Venetian awnings are widely used outdoors, serving not only to provide shade and rain protection but also to enhance the overall architectural style. They are popular with consumers because the opening and closing of the louvers can be adjusted relatively freely according to outdoor weather and light conditions, resulting in comfortable and even lighting inside the awning.

[0003] In existing louvered sunshade structures, the rotation of the blades is generally achieved by linking the blades together and then driving one of the blades to rotate, thereby adjusting the rotation of the entire louvered structure. However, the rotation of the blades usually requires connecting the blades to the blade base. A Chinese utility model patent with application number 202321323487.8 discloses a support component, a frame connection structure, and a louvered sunshade. The support component uses a stop cover and an insert to embed into the support body to limit the rotation of the rotating parts, so that the blades can be effectively adjusted and rotated due to the limited position. However, in the above structure, the design of the support body requires steps such as slotting to facilitate the insertion of the insert, which results in inefficient production setup. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of the aforementioned background technology by providing a blade base that is easy to manufacture, ensures effective limiting of rotating parts, and guarantees service life, as well as a louvered sunshade using the base.

[0005] To achieve the above objectives, this utility model adopts the following technical solution:

[0007] A further improvement of the blade base of this utility model is that the groove is U-shaped and opens downward from the middle of the upper end face of the bottom body. The lower end of the bottom body is provided with a base. One side of the bottom body is provided with two sets of transverse protrusions arranged away from the other side. The two sets of protrusions are distributed vertically, with the lower protrusion being longer than the upper protrusion. The upper end of the other side of the bottom body is provided with an arc-shaped part. One side of the upper body is provided with three sets of horizontal parts distributed vertically. The upper horizontal part is a limiting part, which is placed above the groove and inserted into the arc-shaped part. The middle horizontal part is adapted to the upper horizontal part and the upper protrusion for a snap-fit. The lower horizontal part is adapted to the lower protrusion for a snap-fit. The bottom body is also provided with a hexagonal groove, which is located below the groove.

[0008] A further improvement of the blade base of this utility model is that the upper body has an arc-shaped bend on the side away from the horizontal part, and the opening of the arc-shaped bend faces upward.

[0009] A further improvement of the blade base of this utility model is that a rod is arranged in the groove, the rod has a cylindrical structure, a composite copper sleeve is fitted around the outer periphery of the rod, and one end of the composite copper sleeve is flanged.

[0010] A further improvement of this utility model regarding a blade base is that the bottom and top parts are made of aluminum alloy.

[0011] A louvered sunshade, using the aforementioned blade base, includes two sets of front-to-back horizontal beam frames, with multiple sets of blades arranged between the two sets of horizontal beam frames. Each blade has a blade sealing plate at both its front and rear ends, and the blade sealing plate is connected to the blade base via a rotating rod in the middle. The blade base is fixedly connected to the horizontal beam frames.

[0012] A further improvement of this utility model of a louvered sunshade is that one end of multiple sets of blade sealing plates is connected to a transmission rod, wherein the ends of two adjacent sets of blade sealing plates away from the transmission rod are connected to a drive source.

[0013] A further improvement of this utility model of a louvered sunshade is that both ends of the two sets of crossbeam frames are provided with columns, and a longitudinal beam frame is provided between the front and rear columns of the front and rear crossbeam frames.

[0014] A further improvement of this utility model of a louvered sunshade is that the driving source includes a telescopic cylinder, one end of which is connected to the blade sealing plate and the other end is connected to the column.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] The blade base of this utility model is made of aluminum alloy and features a flanged composite copper sleeve, which enhances hardness, wear resistance, and lubrication, making the blade smoother and more durable during use. On the other hand, the U-shaped groove in the bottom part of the blade base can block the left, right, and downward forces of the rod, while the upper part, in conjunction with the groove, can block the upward force of the rod, ensuring the overall stability of the rod's position. Furthermore, the blade base structure eliminates the need for grooving and other steps, making production convenient and efficient. Attached Figure Description

[0021] 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.

[0022] like Figure 2 and Figure 3 As shown, a four-blade base includes a bottom part and an upper part. The bottom part includes a bottom part body 5, which has a groove 6 for accommodating the 13 rods at both ends of the four blades. The upper part includes an upper part body 9, which has a limiting part that cooperates with the groove 6 to limit the 13 rods. The bottom part and the upper part are fitted with buckles.

[0023] In this embodiment, the 6 groove is U-shaped and is opened downward from the middle of the upper end face of the 5 bottom part body. The lower end of the 5 bottom part body is provided with a 7 base. One side of the 5 bottom part body is provided with two sets of horizontal 8 protrusions arranged in a direction away from the other side. The two sets of 8 protrusions are distributed vertically, and the lower 8 protrusions are longer than the upper 8 protrusions. The upper end of the other side of the 5 bottom part body is provided with a 15 arc-shaped part. One side of the 9 upper part body is provided with three sets of vertically distributed 10 horizontal parts. The upper 10 horizontal parts are limiting parts. The upper 10 horizontal parts are placed above the 6 groove and inserted into the 15 arc-shaped part. The middle 10 horizontal parts are adapted to the upper 10 horizontal parts and the upper 8 protrusions for a snap fastening. The lower 10 horizontal parts are adapted to the lower 8 protrusions for a snap fastening. The 5 bottom part body is also provided with a 12 hexagonal groove, which is located below the 6 groove.

[0024] In this embodiment, the upper body of component 9 is provided with an arc-shaped bend on the side away from the horizontal part of component 10, and the opening of the arc-shaped bend of component 11 faces upward.

[0025] In this embodiment, 13 rods are arranged in the groove 6. The rods 13 are cylindrical structures, and 14 composite copper sleeves are fitted around the outer periphery of the rods 13. One end of the 14 composite copper sleeves is flanged. The 14 composite copper sleeves are in contact with the groove 6 and the 10 horizontal part above it.

[0026] In this embodiment, the bottom and top components are made of aluminum alloy. The 14-composite copper sleeve can be a combination of copper and aluminum. The material of the 4-blade base has been upgraded from the existing plastic steel to aluminum alloy, and flanged composite copper has been added to enhance hardness, wear resistance, and lubrication, making the 4-blade more durable and smoother.

[0027] like Figure 1 and Figure 2 As shown, a louvered sunshade includes two sets of three-beam frames distributed front to back. Multiple sets of four-blade structures are rotatably arranged between the two sets of three-beam frames. Specifically, each of the four-blade structures has a 416-blade end plate at both its front and rear ends. The middle of each 416-blade end plate is connected to a four-blade base via a 13-bar section. The four-blade base is fixedly connected to the three-beam frames. Specifically, the 13-bar section can be a bolted 13-bar structure, passing through the 416-blade end plate. Nuts are provided at both ends of the 416-blade end plate, and tightening the nuts securely connects the 416-blade end plate to the bolted 13-bar section.

[0028] In this embodiment, multiple sets of 416-blade sealing plates are connected at one end to a transmission rod 17, with the ends of two adjacent sets of 416-blade sealing plates furthest from the transmission rod 17 connected to a drive source 18.
