Description

Technical Field

[0001] This utility model relates to the field of pressure strip technology, and in particular to a novel pressure strip. Background Technology

[0002] Existing roller blind fabric-covered lower beams mostly use fiberglass rods to pass through the fabric-covered lower beam to fix the roller blind fabric. However, there are many problems. The fiberglass rods cannot be pressed in from the front opening of the lower beam and can only be inserted from the side notch. Moreover, the thickness of the rods affects the difficulty of insertion and the fixing effect on the fabric. If they are too thick, they cannot be inserted or are difficult to insert. If they are too thin, the fixing is not firm and the fabric is not flat, which affects the aesthetics of the process. This utility model aims to solve the above problems. Utility Model Content

[0003] The purpose of this utility model is to solve the problems mentioned in the background art and to propose a new type of pressure strip.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a novel pressure strip, comprising a pressure strip body, wherein a placement groove is provided on the pressure strip body, the pressure strip body is made of PVC material by extrusion process, and the whole is Y-shaped structure, used to cooperate with the lower beam of the roller blind to fix the roller blind fabric.

[0005] Preferably, the pressure strip body can be pressed down from the opening on the front of the lower beam of the roller blind by the pressure plate, so that the end of the fabric placed in the placement groove is stuck in the guide groove of the lower beam of the roller blind.

[0006] Preferably, the top end of the pressure strip body has a certain degree of elasticity.

[0007] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the Y-shaped pressure strip body, which has a placement groove, is pressed down from the opening on the front of the lower beam of the roller blind using a pressure plate. With the help of the elasticity of the top of the pressure strip body, after the pressure strip is pressed into the guide groove, the end of the fabric in the placement groove will be tightly locked in the guide groove of the lower beam of the roller blind. The operation is very simple, and there is no need to insert the fiberglass rod from the side notch as in the past. This greatly improves the efficiency of fixing the roller blind fabric and can effectively fix the fabric. At the same time, it can effectively fix the fabric and avoid problems such as poor fixing and poor fabric flatness caused by the fixing parts being too thick or too thin. This makes the roller blind fabric present good flatness and improves the overall aesthetics of the roller blind. Attached Figure Description

[0009] Legend: 1. Pressure strip body; 2. Placement groove. Detailed Implementation

[0010] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0011] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0012] Example 1: As Figure 1 - Figure 2 As shown, this utility model provides a technical solution: a novel pressure strip, including a pressure strip body 1, with a placement groove 2 provided on the pressure strip body 1. The pressure strip body 1 is made of PVC material through an extrusion process and has an overall Y-shaped structure. It is used to cooperate with the lower beam of the roller blind to fix the roller blind fabric. The pressure strip body 1 can be pressed down from the opening on the front of the lower beam of the roller blind by a pressure plate, so that the end of the fabric placed in the placement groove 2 is stuck in the guide groove of the lower beam of the roller blind. The top of the pressure strip body 1 has a certain elasticity.

[0013] The beneficial effects achieved in this embodiment 1 are as follows: By using PVC material and employing extrusion technology to manufacture the Y-shaped pressure strip body 1, the PVC material itself has good plasticity and a certain degree of flexibility, allowing the pressure strip to be precisely molded into a Y shape that meets the usage requirements during the manufacturing process. It is also less prone to damage and the cost is relatively reasonable. The Y-shaped structure design allows it to better fit the shape of the lower beam guide groove when used with the roller blind lower beam. Compared to the traditional single columnar structure of fiberglass rods, this greatly increases the contact area between the pressure strip body 1 and the lower beam guide groove and the fabric, thus more firmly fixing the fabric within the guide groove and effectively preventing the fabric from loosening or shifting. The pressure strip body 1 can be pressed down from the front opening of the lower beam of the roller blind using a pressure plate, changing the traditional... The traditional method of inserting fiberglass rods only through side notches is limited. Pressing them down from the front opening is more intuitive and convenient. Operators can more easily and accurately place the pressure strip in the appropriate position without having to search for the side notch and try to insert it with difficulty. This greatly improves the efficiency of fixing the roller blind fabric and reduces operation time and labor costs. The elasticity of the top of the pressure strip body 1 plays a key role. After the pressure strip is pressed down into the guide groove of the lower beam of the roller blind by the pressure plate, this elasticity can adaptively apply a moderate and continuous elastic force to the end of the fabric stuck in the guide groove, so that the fabric can fit tightly against the guide groove wall, further enhancing the fixing effect of the fabric. Even under the conditions of frequent use of the roller blind and being pulled by external forces, the fabric is not easy to fall out of the guide groove.

[0014] The working principle of this embodiment is as follows: In use, the end of the roller blind fabric is first arranged and placed in the placement groove 2 of the pressure strip body 1. The placement groove 2 provides a dedicated positioning space for the end of the fabric, allowing it to be accurately positioned and relatively neat. Then, the pressure plate acts on the pressure strip body 1, pressing it down smoothly from the opening on the front of the lower beam of the roller blind. Since the Y-shaped structure of the pressure strip body 1 can fit well with the shape of the lower beam guide groove, the pressure strip body 1 can smoothly enter the guide groove along its contour during the pressing process. When the pressure strip body 1 is fully inserted into the guide groove, the elasticity at its top begins to play a role. Due to its own elastic deformation, it generates an elastic force that squeezes the end of the fabric in the placement groove 2 towards the guide groove wall. Under the action of this elastic force, the end of the fabric is tightly stuck in the guide groove of the lower beam of the roller blind, thereby achieving stable and effective fixation of the roller blind fabric. This ensures that the fabric maintains good flatness and stability during subsequent opening, closing, and daily use of the roller blind, guaranteeing the normal function and aesthetics of the roller blind.

[0015] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
