Description

Technical Field

[0001] The utility model relates to the technical field of PVC edge banding strips, in particular to a novel PVC edge banding strip. Background Art

[0002] PVC edge banding is a material used in furniture manufacturing and decoration, usually made of polyvinyl chloride (PVC). PVC edge banding is used to wrap the edges of furniture to increase its durability and aesthetics. It can also prevent the edges of furniture from moisture, wear or cracking and provide additional protection.

[0003] Patent document with application number 202321006578.9 discloses a high-strength PVC edge banding strip, including an edge banding strip body, wherein the edge banding strip body is provided with at least one group of pressure relief cavities; a pressure relief reinforcement is provided in the pressure relief cavity, and the pressure relief reinforcement is composed of two cross-arranged pressure relief sheets; pressure relief air holes penetrating the pressure relief cavity are provided on both sides of the edge banding strip body, and pressure relief grooves are provided on both sides of the edge banding strip body; and anti-slip patterns are provided on the upper surface and the lower surface of the edge banding strip body, respectively. After the high-strength PVC edge banding strip is squeezed, the air in the pressure relief cavity is discharged through the pressure relief air holes, thereby improving the compressive strength of the PVC edge banding strip. However, after the high-strength PVC edge banding strip is squeezed for a long time, the resilience of the high-strength PVC edge banding strip is reduced, and it is difficult for external air to enter the pressure relief cavity through the pressure relief air holes in a short time, thereby reducing the compressive strength of the subsequent PVC edge banding strip. Utility Model Content

[0004] The purpose of the utility model is to provide a novel PVC edge banding strip in order to solve the above problems.

[0005] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0006] A new type of PVC edge banding, comprising:

[0007] A main body (1), wherein a plurality of first pressure-relief chambers (2) and a second pressure-relief chamber (3) are arranged in the main body (1); a plurality of elastic cross bars (4) are arranged in the first pressure-relief chamber (2) and / or the second pressure-relief chamber (3); a plurality of third pressure-relief chambers (5) are arranged between the first pressure-relief chamber (2) and the second pressure-relief chamber (3); and a plurality of pressure-relief air holes (6) penetrating the first pressure-relief chamber (2) and / or the second pressure-relief chamber (3) are arranged on both sides of the main body (1).

[0008] Furthermore: a plurality of pressure relief grooves (7) are provided on both sides of the main body (1).

[0009] Furthermore: the transverse surface of the pressure relief groove (7) is a U-shaped structure.

[0010] Furthermore: the cross section of the third pressure relief chamber (5) is a circular structure.

[0011] Furthermore: the number of the third pressure relief chambers (5) is determined according to the thickness of the body (1).

[0012] Furthermore: each of the third pressure-slowing chambers (5) is arranged in a periodic array.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. By setting the first pressure relief chamber and the second pressure relief chamber in the main body, the PVC edge banding strip is buffered after being squeezed, thereby improving the compressive strength of the PVC edge banding strip;

[0015] 2. By setting the pressure relief pores, the air in the first pressure relief chamber and the second pressure relief chamber is released after being squeezed, so that the PVC edge banding strip is further buffered after being squeezed, thereby improving the compressive strength of the PVC edge banding strip;

[0016] 3. By arranging elastic horizontal bars in the first pressure relief chamber and the second pressure relief chamber, when the PVC edge sealing strip is released from the extrusion, the first pressure relief chamber and the second pressure relief chamber can more quickly restore to their original shapes when the air is discharged under the extrusion, so as to more quickly inhale the external air into the first pressure relief chamber and the second pressure relief chamber, thus shortening the time for replenishing the air in the first pressure relief chamber and the second pressure relief chamber, and thus improving the compressive strength of the PVC edge sealing strip;

[0017] 4. By setting the third pressure relief chamber, when the PVC edge sealing strip is squeezed and the air in the first pressure relief chamber and the second pressure relief chamber is exhausted, the PVC edge sealing strip can still be buffered by the third pressure relief chamber, thereby improving the compressive strength of the PVC edge sealing strip;

[0018] 5. By setting the pressure relief groove, the PVC edge banding can be buffered when it is squeezed, thereby improving the compressive strength of the PVC edge banding. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The utility model is further described below in conjunction with the accompanying drawings:

[0028] like Figure 1-Figure 3 As shown, a new type of PVC edge banding includes:

[0029] The main body 1 is provided with two first pressure-relief chambers 2 and two second pressure-relief chambers 3. By arranging the first pressure-relief chamber and the second pressure-relief chamber in the main body, the PVC edge banding is buffered after being squeezed, thereby improving the compressive strength of the PVC edge banding; 10 pressure-relief air holes 6 penetrating the first pressure-relief chamber 2 are arranged on both sides of the main body 1, and 10 pressure-relief air holes 6 penetrating the second pressure-relief chamber 3 are arranged on both sides of the main body 1. Through the arrangement of the pressure-relief air holes, after the first pressure-relief chamber and the second pressure-relief chamber are squeezed, the air in the first pressure-relief chamber and the second pressure-relief chamber is released, thereby further buffering the PVC edge banding after being squeezed, thereby improving the compressive strength of the PVC edge banding; 3 elastic cross bars 4 are arranged in the first pressure-relief chamber 2 and the second pressure-relief chamber 3. By arranging elastic cross bars in the first pressure-relief chamber and the second pressure-relief chamber, when the PVC edge banding is squeezed and released, the first pressure-relief chamber and the second pressure-relief chamber are released after being squeezed. When the air is exhausted, it returns to its original shape more quickly, so that the external air can be sucked into the first pressure relief chamber and the second pressure relief chamber more quickly, shortening the time for replenishing air in the first pressure relief chamber and the second pressure relief chamber, thereby improving the compressive strength of the PVC edge banding; between the first pressure relief chamber 2 and the second pressure relief chamber 3, there are 24 third pressure relief chambers 5 with a circular cross-section and arranged in an array periodically; the number of the third pressure relief chambers 5 is determined according to the thickness of the main body 1. Through the setting of the third pressure relief chamber, when the PVC edge banding is squeezed and the air in the first pressure relief chamber and the second pressure relief chamber is exhausted, the PVC edge banding can still be buffered by the third pressure relief chamber, thereby improving the compressive strength of the PVC edge banding; 8 pressure relief grooves 7 with a U-shaped structure on both sides of the main body 1 are provided. Through the setting of the pressure relief grooves, the PVC edge banding can be buffered when it is squeezed, thereby improving the compressive strength of the PVC edge banding.

[0030] Working principle: When in use, the PVC edge banding is fixedly installed on the doors and windows. During the process of closing windows and doors, the doors and windows collide with the door frames and window frames, and the PVC edge banding body is squeezed; when the PVC edge banding body is squeezed, the upper and lower surfaces of the PVC edge banding body are simultaneously retracted toward the center. During the retraction process, the pressure is buffered through the first pressure-relief chamber, the second pressure-relief chamber and the third pressure-relief chamber; the air in the first pressure-relief chamber and the second pressure-relief chamber is discharged through the pressure-relief pores; when the pressure is gone, the outside air will enter the first pressure-relief chamber and the second pressure-relief chamber through the pressure-relief pores, and since the first pressure-relief chamber and the second pressure-relief chamber are provided with elastic cross bars, it is helpful for the outside air to enter the first pressure-relief chamber and the second pressure-relief chamber through the pressure-relief pores, so that the time for the outside air to enter the first pressure-relief chamber and the second pressure-relief chamber through the pressure-relief pores is shortened, thereby improving the compressive strength of the PVC edge banding.

[0031] The basic principles, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements shall fall within the scope of the utility model to be protected.
