Description

Technical Field

[0001] The utility model relates to a magnetic door curtain, in particular to a magnetic door curtain edge wrapping structure. Background Art

[0002] Magnetic door curtains have been widely used at the entrances and exits of shopping malls, buildings and other places with a large flow of people. When people enter and exit, the door curtain can be quickly opened for easy passage. After people pass through, the door curtains can quickly attract each other under the action of their own weight and the magnetic attraction of the magnetic strips, reducing the air circulation inside and outside the building on the premise of ensuring the passage of people. The existing magnetic door curtain structure fixes the magnetic strip on the side edge of the door curtain board through a wrapping strip made of plastic or rubber material, and the wrapping strip protects the magnetic strip and the door curtain board. However, the wrapping strip is prone to breakage after long-term use, especially at the lower end of the wrapping strip, which will cause frequent friction with the ground during use, resulting in wear and damage of the wrapping strip. After losing the protection of the wrapping strip, the magnetic strip and the door curtain board are exposed and prone to damage, affecting the sealing performance of the magnetic door curtain. Content of the Utility Model

[0003] The purpose of the utility model is to provide a magnetic door curtain edge wrapping structure to solve the problem that the existing wrapping strip of the magnetic door curtain is prone to breakage and cannot protect the internal magnetic strip and door curtain board.

[0004] The utility model is realized as follows: a magnetic door curtain edge wrapping structure includes a door curtain board, a magnetic strip and a wrapping strip. The magnetic strip is located at the side edge of the door curtain board. Two side edges of the wrapping strip are respectively connected to the edges of the front and back surfaces of the door curtain board, and the wrapping strip wraps and fixes the magnetic strip. The wrapping strip includes a body layer, and a grid-shaped structure groove is opened on one side surface of the body layer, and a reinforcing strip is filled in the structure groove.

[0005] As a further improvement of the magnetic door curtain edge wrapping structure of the utility model, the reinforcing strip is a high-strength fiber, and the high-strength fiber is cross-laid along the grid-shaped structure groove.

[0006] As a further improvement of the magnetic door curtain edge wrapping structure of the utility model, the structure groove is located on the inner side surface of the body layer.

[0007] As a further improvement of the magnetic door curtain edge wrapping structure of the utility model, the structure groove includes uniformly distributed transverse grooves and longitudinal grooves. The direction of the transverse grooves is consistent with the width direction of the door curtain board, and the direction of the longitudinal grooves is consistent with the length direction of the door curtain board.

[0008] As a further improvement of the edge - wrapping structure of the magnetic - attraction door curtain of the present utility model, the edge - wrapping strip is adhered to the surface of the door - curtain plate through an adhesion structure uniformly distributed along the length direction of the door - curtain plate. The adhesion structure is in the shape of a long strip extending outward along the width direction of the door - curtain plate from the edge of the edge - wrapping strip. The height of the adhesion structure is n times the spacing between two adjacent transverse grooves, where n is greater than or equal to 1, and the upper and lower sides of the adhesion structure coincide with the transverse grooves. The spacing between two adjacent adhesion structures is the same as the spacing between two adjacent transverse grooves.

[0009] As a further improvement of the edge - wrapping structure of the magnetic - attraction door curtain of the present utility model, the width of the transverse grooves and the longitudinal grooves is 0.5 - 2 mm, and the spacing between two adjacent transverse grooves and the spacing between two adjacent longitudinal grooves are 1 - 5 mm.

[0011] The present utility model adopts a new edge - wrapping structure for the magnetic - attraction door curtain. A grid - shaped structure groove is opened on the body layer of the edge - wrapping strip, and a reinforcing strip is filled in the structure groove.

[0017] The following will describe the specific embodiments of the present utility model with reference to the accompanying drawings.

[0018] Figure 1 What is shown is a part of the side of the magnetic - attraction door curtain of the present utility model. Figure 2It is a cross-sectional view of the side of the magnetic curtain of the present utility model. The edge wrapping structure of the magnetic curtain of the present utility model includes a curtain board 1, a magnetic strip 3, an edge wrapping strip 2 and other structures.

[0019] The magnetic strip 3 and the edge wrapping strip 2 are respectively arranged on both sides of the curtain board 1, and the magnetic strip 3 is coated and fixed on the side of the curtain board 1 through the edge wrapping strip 2. The cross-section of the magnetic strip 3 is generally rectangular, and the thickness of the magnetic strip 3 is greater than the thickness of the curtain board 1. The two sides of the edge wrapping strip 2 are respectively connected to the edges of the front and back surfaces of the curtain board 1, and the magnetic strip 3 is located in the space surrounded by the edge wrapping strip 2.

[0020] Among them, the edge wrapping strip 2 includes a body layer 2-1, and a grid-like structure groove 2-2 is formed on one side of the body layer 2-1, and a reinforcing strip 2-3 is filled in the structure groove 2-2.

[0021] The reinforcing strip 2-3 is specifically a cluster structure formed by high-strength fibers. The high-strength fibers can be high-strength polyester filaments, glass fibers, polyester fibers, nylon fibers, etc. The length direction of the high-strength fibers is consistent with the direction of the structure groove 2-2, and generally the high-strength fibers are cross-laid along the grid-like structure groove 2-2.

[0022] During production, first lay the grid-like high-strength fiber reinforcing strips 2-3 on the body layer 2-1 of the edge wrapping strip 2 along two mutually perpendicular directions, and then press the high-strength fiber reinforcing strips 2-3 into the surface of the body layer 2-1 of the edge wrapping strip 2 at a certain temperature to form the grid-like structure groove 2-2, and the high-strength fiber reinforcing strips 2-3 are firmly embedded in the structure groove 2-2.

[0023] The reinforcing strip 2-3 forms a grid structure to improve the structural strength of the edge wrapping strip 2. Under the reinforcement of the high-strength fibers, it is difficult to damage the edge wrapping strip 2 even under external forces. At the same time, the high-strength fibers can prevent the extension of wear. During long-term use, the grid-like reinforcing strip 2-3 can prevent the damage of the edge wrapping strip 2.

[0024] During use, the side with the structure groove 2-2 or the reinforcing strip 2-3 is the inner side of the edge wrapping strip 2, so that the outer side of the edge wrapping strip 2 is smooth and beautiful. Even if the body layer of the edge wrapping strip wears after long-term use, the inner mesh reinforcing strip can protect the internal magnetic strip and the curtain board.

[0025] As Figure 3 shown, the structure groove 2-2 includes uniformly distributed transverse grooves 2-4 and longitudinal grooves 2-5. The direction of the transverse grooves 2-4 is consistent with the width direction of the curtain board 1, and the direction of the longitudinal grooves 2-5 is consistent with the length direction of the curtain board 1. The transverse grooves 2-4 and the longitudinal grooves 2-5 intersect with each other to form a square grid.

[0026] As Figure 1As shown in the figure, the edge strip 2 is adhesively bonded to the surface of the curtain panel 1 through the bonding structure 4 evenly distributed along the length direction of the curtain panel 1. The bonding structure 4 is a long strip extending outward from the edge of the edge strip 2 along the width direction of the curtain panel 1.

[0027] The bonding structure 4 can be realized by glue, or by heating and extruding the corresponding area on the edge strip 2, or by other means to bond the inner side surface of the edge strip 2 to the surface of the curtain panel 1.

[0028] Since the bonding structure 4 extends outward from the edge of the edge strip 2 along the width direction of the curtain panel 1 and has a certain length, it is not easy for the edge position of the edge strip 2 to separate from the surface of the curtain panel 1.

[0029] The magnetic curtain is produced as a very long coil, which includes the curtain panel 1, the magnetic strips 3 on both sides and the edge strip 2. Before installing the curtain, cut multiple curtains of corresponding lengths as needed.

[0030] Therefore, as Figure 4 shown, in this embodiment, specific restrictions are imposed on the dimensional relationship between the bonding structure 4 and the edge strip 2. The shaded part represents the bonding structure, and the dotted part represents the structure groove. Among them, the height of the bonding structure 4 is n times the distance between two adjacent transverse grooves 2-4, where n is greater than or equal to 1, and the upper and lower sides of the bonding structure 4 coincide with the transverse grooves 2-4. The distance between two adjacent bonding structures 4 is the same as the distance between two adjacent transverse grooves 2-4.

[0031] Among them, n can specifically be 2, that is, the height of the bonding structure 4 (the dimension along the length direction of the curtain panel 1) is twice the distance between two adjacent transverse grooves 2-4.

[0032] The width of the transverse groove 2-4 and the longitudinal groove 2-5 is 0.5-2 mm, and the distance between two adjacent transverse grooves 2-4 and the distance between two adjacent longitudinal grooves 2-5 are 1-5 mm. The transverse reinforcing strips 2-3 and the longitudinal reinforcing strips 2-3 form a relatively dense grid structure, thus greatly enhancing the structural strength of the edge strip 2.

[0033] When cutting the curtain, the cutting line may pass through the bonding structure 4 or pass through the position between two bonding structures 4. When the cutting line passes through the bonding structure 4 or coincides with the lower edge of the bonding structure 4, it can effectively ensure that the lower edge of the edge strip 2 does not separate from the surface of the curtain panel 1. When the cutting line passes through the position between two bonding structures 4, since the distance between adjacent two bonding structures 4 is the same as the distance between adjacent two transverse grooves 2-4, the cutting line will pass through the reinforcing strip 2-3 in the transverse groove 2-4 or pass through the position between two transverse reinforcing strips 2-3. At this time, on the one hand, since the distance from the cutting line to the lower edge of the bonding structure 4 is very small, although the lower edge of the edge strip 2 is not connected to the curtain panel 1, it will not easily separate from the surface of the curtain panel 1; on the other hand, under the strengthening effect of the transverse reinforcing strip 2-3 and several longitudinal reinforcing strips 2-3, the wear of the lower edge of the edge strip 2 can be slowed down.

[0034] In addition, an adhesive layer 5 is provided on one side surface of the magnetic strip 3 along the length direction, and the adhesive layer 5 is located on any one of the three side surfaces where the magnetic strip 3 is in direct contact with the inner side surface of the edge strip 2. The magnetic strip 3 is connected to the inner side surface of the edge strip 2 through the adhesive layer 5. The adhesive layer 5 can fix the magnetic strip 3 on the edge strip 2, thereby preventing the magnetic strip 3 from sliding down during use and increasing the friction between the magnetic strip 3 and the ground.
