Description

Technical Field

[0001] The utility model relates to the technical field of building decoration materials, in particular to an anti-collision and sound-proof cap for a rolling curtain. Background Art

[0002] In office spaces, blackout roller blinds are widely used as standard equipment in offices, conference rooms and other office spaces. In actual use, the lower rod of a manual blackout roller blind is made of metal or plastic, and hard end caps are used for decoration at both ends. Under the action of wind, the fluttering of the roller blind drives the lower rod and end cap of the roller blind to repeatedly collide with windows, walls near windows, etc., generating noise. This high-frequency and irregular impact noise seriously affects the acoustic environment in the office space.

[0003] To avoid such impact noise, the only option is to close windows or roll up blackout curtains, which either makes the indoor space lose its natural ventilation function or loses its shading function. Especially in high-rise buildings, most of them are closed spaces that use mechanical ventilation. Even when the temperature is suitable, windows cannot be opened for ventilation, which increases operating costs and is not conducive to energy conservation and emission reduction.

[0036] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0037] In the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, "plurality" means two or more, unless otherwise clearly and specifically defined.

[0038] In the description of the present application, the term "for example" is used to mean "used as an example, illustration or description". Any embodiment described as "for example" in the present application is not necessarily to be construed as being more preferred or advantageous than other embodiments. In order to enable any technician in the field to implement and use the utility model, the following description is given. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the utility model can be implemented without using these specific details. In other examples, well-known structures and processes will not be elaborated in detail to avoid unnecessary details that make the description of the utility model obscure. Therefore, the utility model is not intended to be limited to the embodiments shown, but is consistent with the widest range of principles and features disclosed in the present application.

[0039] In order to solve the problem of noise caused by the upper and lower rods 3 of the roller blinds 4 made of metal, plastic, etc. repeatedly hitting the windows 5 or walls 6 under the action of wind, this embodiment provides an anti-collision and silent cap for the roller blinds, see Figure 1-Figure 6 As shown, it includes an integrally formed cap body 1 and an adhesive body 2 arranged in the cap body 1; wherein, a groove 11 adapted to be plugged with the end of the lower rod 3 on the rolling curtain 4 is opened on one side of the cap body 1, that is, the end of the cap body 1 plugged with the lower rod 3 is opened with the groove 11, so that the end of the lower rod 3 is plugged into the cap body 1. At this time, referring to Figure 7 , Figure 8 As shown, when the lower rod 3 hits the window 5 or the wall 6 under the action of wind, the cap body 1 first contacts the window 5 or the wall 6, reducing the contact area with the window 5 or the wall 6, thereby reducing the noise generated by the collision. In order to avoid noise, the cap body 1 is an elastomer. Furthermore, the material of the elastomer is selected from one of nitrile rubber, EPDM rubber, silicone, PVC, TPV, TPE, TPR, and SEBS, so that when the elastic cap body 1 hits the window 5 or the wall 6, the sound generated by the collision is effectively reduced. In order to facilitate the installation of the cap body 1, an open groove 12 connected to the groove 11 is provided on the cap body 1, and the open groove 12 and the groove 11 share a vertical center line; wherein, the open groove 12 is provided along the length direction of the cap body 1, and its opening length is less than the length of the cap body 1. Since the cap body 1 is made of elastic material, when installing, the open groove 12 is opened by hand, and then the end of the lower rod 3 is inserted into the groove 11.

[0040] The adhesive body 2 is arranged on the inner wall of the groove 11 to adhere to the end of the lower rod 3, so that the end of the lower rod 3 wrapped in the groove 11 is fastened therein after being adhered by the adhesive body 2 and does not separate from the cap body 1. Furthermore, the groove 11 is opened along the length direction of the cap body 1 and its length is less than the length of the cap body 1 to better wrap the end of the lower rod 3. In the specific implementation process, the size of the cap body 1 can be set according to the size of the lower rod 3, so that the end of the lower rod 3 is wrapped in the groove 11. For example, the length×width×thickness of the cap body 1 is 50×50×30 (mm).

[0041] Preferably, the adhesive body 2 is 3M adhesive backing and is symmetrically arranged on the two inner walls of the groove 11. Specifically, after the open groove 12 is opened, the release paper on the 3M adhesive backing is torn off, and then the end of the lower rod 3 is inserted therein, and then the open groove 12 is closed, so that the adhesive surface in the groove 11 is bonded to the side wall of the end of the lower rod 3, and then the cap body 1 is bonded and fixed to the lower rod 3. During use, the cap body 1 is provided on both the left and right ends of the lower rod 3.

[0042] In the specific implementation process, since the cap body 1 is small in size and made of soft and elastic material, in order to enhance the stability of holding during operation and facilitate operation, a plurality of anti-slip protrusions 13 are provided on the outer surface of the cap body 1. Preferably, the material of the anti-slip protrusions 13 is made of elastic material, which can be consistent with the material of the cap body 1. If it is made of hard material, the anti-slip protrusions 13 are not provided on the side facing the wall 5, but are only provided on the side facing away from the wall 5.

[0043] In order to enhance the anti-slip effect, it also reduces materials and costs to a certain extent. Figure 9-12 , the anti-slip protrusion 13 is provided with an inner concave portion 131, and the inner concave portion 131 and the anti-slip protrusion 13 are coaxial;

[0044] In order to adapt to the inertia of holding by human body, the anti-slip protrusions 13 are symmetrically arranged on the two outer side walls of the cap body 1 .

[0045] It should be noted that in the above embodiments, the description of each embodiment has its own emphasis, and for parts that are not described in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0046] Although the preferred embodiments of the utility model have been described, those skilled in the art may make other changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the utility model.

[0047] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
