Description

Technical Field

[0001] This utility model belongs to the field of louver technology, and particularly relates to a louver flipping force linkage structure and louvers. Background Technology

[0002] Venetian blinds feature flexibly adjustable slats. In terms of sun shading, Venetian blinds not only block ultraviolet radiation but also regulate indoor light. For ventilation, the fixed installation and sturdy construction of Venetian blinds allow you to comfortably enjoy a cool breeze without any worries. While curtains may allow glimpses of the interior, the layered design of Venetian blinds ensures privacy.

[0003] The louver design utilizes a linkage rod to drive multiple sets of linkages that are individually linked to the louver blades, enabling the louver blades to rotate synchronously and thus opening and closing the louver. In contrast, most existing technologies use push rods to drive the linkage rods directly. During the opening process, the louver requires a strong thrust due to its sealing structure. However, after the louver is opened, the push rod device loses the restraining force of the sealing element, which can easily cause the louver blades to bear strong stress. This can lead to insufficient stability in the blade operation during the opening process and may cause blade damage. Utility Model Content

[0004] This utility model provides a louver flipping force linkage structure, which aims to solve the problem that the current louver lacks an effective structure to resist the strong thrust applied by the push rod during the initial opening period, resulting in insufficient stability of the blade operation state during the opening process and easy damage to the blade.

[0005] This utility model is implemented as follows: a louvered folding force-linking structure includes:

[0006] A linkage rod, wherein the linkage rod is provided with a linkage shaft hole for connecting the louvers;

[0007] A force distribution unit is disposed above a linkage rod. The force distribution unit includes a fixed base and a deflection block rotatably connected to the fixed base. The front end of the deflection block is provided with a slot, and the linkage rod extends into the slot.

[0008] The fixed base is provided with a deflection groove, the deflection block is disposed in the deflection groove, the deflection block is provided with guide balls, and the side wall of the deflection groove is provided with a guide groove adapted to the guide balls.

[0009] Preferably, the deflection block is provided with a deflection rod, which is assembled in the deflection groove by a bearing.

[0010] Preferably, the fixed base is provided with a deflection chamber, and one end of the deflection rod extends into the deflection chamber; the part of the deflection rod extending into the deflection chamber is provided with a torsion spring and a limiting plate for limiting the torsion spring.

[0011] Preferably, the guide ball is disposed on the end face parallel to the rotation plane of the deflection block and the deflection rod, and the guide ball slides along the guide groove.

[0012] Preferably, the slot is located at the end of the deflection block away from the deflection rod, and the end face of the slot that contacts the linkage rod has an arc-shaped structure.

[0013] Preferably, the width of the slot is the same as the width of the linkage rod, and the slot engages with the outside of the linkage rod.

[0014] Preferably, the linkage rod is provided with a limiting groove, the limiting grooves are respectively provided on both sides of the linkage rod, and the part of the linkage rod with the limiting groove extends into the slot.

[0015] A louver, wherein the louver adopts a louver flipping force linkage structure as described in any one of the claims.

[0016] Compared with the prior art, the embodiments of this application have the following main advantages:

[0017] In the louver flipping force linkage structure provided by this utility model, during the louver opening process, the linkage rod will move closer to the force distribution unit under the action of the push rod. During the movement of the linkage rod, the force distribution unit will apply a downward pressure to the linkage rod. Under the dual action of the force distribution unit and the push rod, the movement state of the linkage rod pulling the linkage rod can be more stable. The force applied by the force distribution unit offsets the strong thrust applied by the push rod during the initial opening period, so that the blade running state is not stable enough during the opening process, which may easily cause blade damage.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0029] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0030] This utility model embodiment provides a louvered folding force-linking structure, such as Figures 1-6 As shown, the louver tilting force linkage structure includes:

[0031] Linkage rod 200, wherein the linkage rod 200 is provided with a linkage shaft hole 210 for connecting the louvers.

[0032] A force distribution unit 100 is disposed above the linkage rod 200. The force distribution unit 100 includes a fixed base 120 and a deflection block 110 rotatably connected to the fixed base 120. The front end of the deflection block 110 is provided with a slot 114, and the linkage rod 200 extends into the slot 114.

[0033] The fixed base 120 is provided with a deflection groove 121, the deflection block 110 is disposed in the deflection groove 121, the deflection block 110 is provided with a guide ball 113, and the side wall of the deflection groove 121 is provided with a guide groove 122 adapted to the guide ball 113.

[0034] In this embodiment, the linkage rod 200 is used to deflect the connecting rod 300 that is connected to the louver body. During the louver flipping process, the linkage rod 200 is deflected to a certain extent by the push rod (not shown in this application). The movement of the linkage rod 200 causes the connecting rod 300 of the louver body to deflect, thereby allowing the louver to open and close. The push rod power can be an electric hydraulic push rod.

[0035] The force distribution unit 100 helps the linkage rod 200 operate more stably. The main function of the force distribution unit 100 is to apply resistance to the deflection movement of the linkage rod 200. When the louver is opened, the linkage rod 200 will move closer to the force distribution unit 100 under the action of the push rod. During the movement of the linkage rod 200, the force distribution unit 100 will apply a downward force to the linkage rod 200. Under the dual action of the force distribution unit 100 and the push rod, the movement state of the linkage rod 200 can be made more stable. At the same time, the louver can be maintained by the dual forces after it is opened, reducing the influence of the external environment on the louver. This can help the push rod to distribute the force in one direction and improve the service life of the push rod.

[0036] In a preferred embodiment of this invention, the deflection block 110 is provided with a deflection rod 111, which is mounted in the deflection groove 121 via bearings. The deflection rod 111 is provided with a first bearing 124, a second bearing 125, and a third bearing 126. The first bearing 124 and the second bearing 125 are disposed on the side wall of the deflection groove 121. The fixed base 120 is provided with a deflection chamber 123, which communicates with the deflection groove 121. One end of the deflection rod 111 extends into the deflection chamber 123 after passing through the second bearing 125. The third bearing 126 is disposed at the end of the deflection rod 111, and the deflection rod 111 is mounted in the deflection chamber 123 at the end away from the deflection groove 121 via the third bearing 126.

[0037] The portion of the deflection rod 111 that extends into the deflection chamber 123 is provided with a torsion spring 130 and a limiting plate 112 that restricts the torsion spring 130; the torsion spring 130 provides a deflection force so that the force distribution unit 100 maintains downward pressure on the linkage rod 200;

[0038] In this embodiment, the deflection rod 111 and the fixed base 120 adopt a simply supported beam structure, which makes the deflection block 110 more stable during the deflection process and can better provide a stabilizing effect.

[0039] In a preferred embodiment of this invention, the guide ball 113 is disposed on the end face parallel to the rotation plane of the deflection block 110 and the deflection rod 111, and the guide ball 113 slides along the guide groove 122.

[0040] In this embodiment, the guide ball 113 adopts a ball structure that can reduce friction. The guide ball 113 can rotate in all directions. During the deflection process, the guide ball 113 contacts and connects with the guide groove 122, avoiding direct contact and friction between the fixed seat 120 and the deflection block 110, thus reducing friction while ensuring motion stability.

[0041] In a preferred embodiment of this invention, the slot 114 is located at the end of the deflection block 110 away from the deflection rod 111, and the end face of the slot 114 that contacts the linkage rod 200 is an arc-shaped structure, which improves the contact effect with the linkage rod 200.

[0042] In this embodiment, the width of the slot 114 can be the same as the width of the linkage rod 200, and the slot 114 engages with the outside of the linkage rod 200;

[0043] In addition to the above-mentioned method, the linkage rod 200 is provided with a limiting groove 220. The limiting groove 220 is provided on both sides of the linkage rod 200. The part of the linkage rod 200 with the limiting groove 220 extends into the slot 114. The width of the part of the linkage rod 200 with the limiting groove 220 is the same as the width of the slot 114. The engaging design here further enhances the stability of the operation between the linkage rod 200 and the force distribution unit 100 and reduces the offset during the movement.

[0044] This utility model embodiment also provides a louver using the above-described louver flipping force linkage structure.
