A type of Venetian blind with adjustable installation width Technical Field
[0001] This utility model relates to the field of Venetian blinds, specifically a Venetian blind with adjustable installation width. Background Technology
[0002] Venetian blinds are a common sunshade and decorative product, widely used in residential, office and commercial spaces.
[0003] Existing Venetian blinds typically use a fixed-width beam structure, and their installation width cannot be adjusted. Therefore, they need to be customized according to the window size during installation. Different window sizes require different specifications of Venetian blinds, which increases production and inventory costs. If the window size is not standard or the installation environment is changed later, the original Venetian blinds may not be compatible and need to be purchased again, resulting in waste of resources. Some adjustable-width Venetian blinds use a simple telescopic rod structure, but lack a reliable locking mechanism, which is prone to loosening during use, affecting stability and service life.
[0004] Therefore, a new type of Venetian blind with adjustable installation width is needed to solve the above problems. Summary of the Invention
[0005] The purpose of this invention is to provide a Venetian blind with adjustable installation width to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a venetian blind with adjustable installation width, comprising a crossbeam and several venetian blades. The crossbeam includes a connecting pipe and two fixing plates. The fixing plates have a telescopic tube on the side facing the connecting pipe. The connecting pipe has a positioning hole. The telescopic tube has a long groove. The connecting pipe has a locking element for fixing the telescopic tube. The venetian blades include a connecting piece and two fixing pieces. The connecting piece and the fixing pieces are slidably connected.
[0007] Preferably, the connecting pipe has a through hole one, and the telescopic pipe has a plurality of through holes two that cooperate with the through hole one.
[0008] Preferably, the locking component includes a first plate and a second plate, the first plate having a screw rod and the second plate having a screw hole, and the first plate and the second plate being connected by the screw rod and the screw hole.
[0009] Preferably, the two sides of the first plate and the second plate are respectively provided with ear plates, and the ear plates are provided with insert rods that can pass through the first through hole and be inserted into the second through hole.
[0010] Preferably, the plate has a countersunk hole, and the head of the screw has a cutting edge.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] 1. In this utility model, the sliding fit between the telescopic tube and the connecting tube, combined with the positioning structure of through hole one and through hole two, allows the installation width of the Venetian blind to be infinitely adjustable according to actual needs, adapting to windows or installation spaces of different sizes, improving the versatility and applicability of the product. The use of locking plate one, plate two and plug rod structure ensures that the telescopic tube and the connecting tube can be firmly fixed after adjustment, preventing loosening or displacement due to external forces during use, and ensuring the long-term stability and safety of the Venetian blind.
[0013] 2. In this utility model, the screw of the locking component adopts a knife-edge design, which is convenient to use tools (such as screwdrivers) or manual tightening, simplifying the adjustment and installation process and improving the user's ease of operation. The connecting piece and fixing piece of the louver are connected by a sliding connection, which is convenient for disassembly and replacement, reducing maintenance costs. At the same time, the detachable design of the locking component also facilitates later adjustment or maintenance. The design of through hole one and multiple through holes two allows for a wider range of extension and contraction of the telescopic tube, and the locking position is selectable, avoiding wear problems caused by a single fixing point and extending service life.
