Description

Technical Field

[0001] The invention belongs to the technical field of rolling blinds and relates to a rolling blind installation structure. Background Art

[0002] In daily life, rolling shutter doors and windows are widely used. There is an upper beam on the top of the rolling shutter doors and windows. When installing the rolling shutter doors and windows, holes are usually drilled on the installation wall first, and then expansion screws are passed through the upper beam and embedded in the holes for installation. However, the installation method of drilling holes and screwing makes the installation of rolling shutter doors and windows more troublesome and inconvenient to disassemble.

[0003] In response to the above problems, people have made various improvements, and some have even applied for patents. For example, Chinese patent literature discloses a Roman blind that can be easily installed [Application No.: 200520002728.4; Authorization Announcement No.: CN2763446Y], which includes a blind body; an upper beam installed at the top of the blind body; a hanging rod installed and fixed on a predetermined wall surface; at least one movable connecting member installed at a predetermined position of the upper beam, which can movably connect or detach the upper beam from the hanging rod.

[0004] This type of Roman blind can be quickly installed and removed through a movable connector. However, after the Roman blind is connected through a movable connector, the upper beam has the problem of rotation and translation relative to the hanging rod, which causes the blind to deviate from the set position, so that the blind cannot play a good shielding role. When the blind is pulled out, the position of the Roman blind often needs to be readjusted, which brings inconvenience to use. Summary of the invention

[0005] The purpose of the present invention is to solve the above problems in the prior art and propose a rolling curtain installation structure, which solves the technical problem of how to make the rolling curtain easy to assemble and disassemble and have good stability after installation.

[0006] The objective of the present invention can be achieved through the following technical solutions: a rolling shutter installation structure, the rolling shutter includes a curtain body and an upper beam located at the top of the curtain body, the installation structure includes a fixed beam for fixing on a predetermined wall, and is characterized in that the installation structure also includes a plurality of hangers and a snap-in piece protruding from the upper beam, one side of the upper beam is snap-connected to the fixed beam, and the other side of the upper beam is connected to the fixed beam through the hanger, the top of the snap-in piece is embedded upward into the fixed beam and cooperates with the gravity of the rolling shutter to limit the hanger.

[0007] The fixed beam can be fixed on the wall in advance. When the rolling curtain needs to be installed, the operator first connects the top of the hanging part with the fixed beam, so that the hanging part is hung on the fixed beam. Then the operator holds the rolling curtain and pushes the rolling curtain to make one side of the upper beam snap with the fixed beam, and then rotates and moves the upper beam upward around the snap position to connect the hanging part with the upper beam. Finally, the rolling curtain is installed on the fixed beam. When disassembling, only the reverse operation is required, and the rolling curtain is easy to disassemble and assemble. The clamping piece cooperates with the gravity of the rolling curtain itself to limit the hanging part. The clamping piece prevents the hanging part from rotating, so that the hanging part is not easy to fall off after being hung on the fixed beam, so that the rolling curtain will not rotate, translate or fall off after installation, and the stability of the rolling curtain after installation is good.

[0008] In the above-mentioned rolling curtain installation structure, the bottom of the fixed beam has a first recessed slot, and the upper beam has a protruding clip strip, which is embedded and hung in the first slot to clip one side of the upper beam to the fixed beam. The rolling curtain can be easily disassembled and assembled by simply pushing the rolling curtain to embed the clip strip into the first slot and clip one side of the upper beam to the fixed beam.

[0009] In the above-mentioned rolling shutter installation structure, the bottom of the fixed beam has a second recessed slot, the upper beam has a third recessed slot, the top of the hanger is embedded and hung in the second slot and the bottom of the hanger is embedded and hooked in the third slot, so that the hanger is connected to the fixed beam, and the top of the clamping piece is embedded in the second slot upward. During installation, the top of the hanger is hung in the second slot, the upper beam is clamped and rotated upward, and the clamping piece first pushes the hanger away. When the top of the clamping piece is embedded in the second slot upward, the bottom of the hanger is embedded and hooked in the third slot, so that the upper beam is fixed to the bottom of the fixed beam. The rolling shutter is easy to install. When disassembling, you only need to push the upper beam in the set direction to slightly offset the upper beam and the fixed beam, and separate the hanger from the upper beam. The rolling shutter is easy to disassemble.

[0010] In the above-mentioned roller blind installation structure, the hanging part includes a main body in the shape of a flat plate, one end of the main body is bent toward one side to form a hanging bar, and the other end of the main body is bent toward the other side to form a lifting bar. When the upper beam is fixed to the bottom of the fixed beam, the hanging bar is embedded in the second card slot, and the lifting bar is embedded in the third card slot, and the main body is against the card plate. The structure of the hanging bar and the lifting bar enables the hanging part to better connect the upper beam and the fixed beam, and improve the stability of the upper beam and the fixed beam after the connection; the main body is against the card plate, which improves the stability of the hanging part, prevents the hanging part from rotating and falling off, and improves the stability of the upper beam and the fixed beam after the connection, so that the roller blind has good stability after installation.

[0011] In the above-mentioned roller blind installation structure, the sum of the thickness of the main body and the thickness of the clamping piece is slightly smaller than the width of the second clamping slot. This structure allows the top of the hanging piece and the clamping piece to be embedded in the second clamping slot, while preventing the hanging piece from deflecting and falling off, thereby improving the stability of the roller blind after installation.

[0012] In the above-mentioned rolling shutter installation structure, when the upper beam is fixed to the bottom of the fixed beam, there is a gap between the top of the clamping piece and the bottom of the second clamping groove. When disassembling, it is necessary to push the upper beam in a set direction. The setting of the gap allows the upper beam to have a certain deviation, which facilitates the disassembly of the rolling shutter.

[0013] In the above-mentioned roller blind installation structure, the hanging bar and the lifting bar are both in the shape of strips, the angle between the hanging bar and the main body is an acute angle, the second card slot has an inclined hanging surface, the angle between the lifting bar and the main body is an acute angle, the third card slot has an inclined lifting surface, when the upper beam is fixed to the bottom of the fixed beam, the hanging bar is against the hanging surface, and the lifting bar is against the lifting surface. This structure makes the hanging parts have good stability after connecting the upper beam and the fixed beam, and the hanging parts are not easy to deflect or detach, thereby improving the stability of the roller blind after installation.

[0014] In the above-mentioned roller blind installation structure, the opening of the second slot has a protruding hanging portion, and the hanging surface is located on the hanging portion. The hanging portion provides a hanging position, and the setting of the hanging portion reduces the notch of the second slot, so that the hanging piece and the connecting piece are not easy to fall off.

[0015] In the above-mentioned rolling shutter installation structure, the second clamping slot, the third clamping slot, the clamping piece, the hanging bar and the lifting bar are all in the shape of long strips, and the surfaces where the clamping piece and the main body are in contact are all flat surfaces. When the upper beam is fixed to the bottom of the fixed beam, a certain external force can be applied to move the hanging piece along the clamping piece. The hanging pieces can be evenly arranged by moving their positions, thereby improving the stability of the connection between the upper beam and the fixed beam, thereby improving the stability of the rolling shutter after installation.

[0016] In the above-mentioned rolling shutter installation structure, the first clamping slot and the clamping strip are both in the shape of long strips, and the cross-sections of the first clamping slot and the clamping strip are both in the shape of angle irons. The opening of the first clamping slot has a protruding clamping portion. When the upper beam is fixed to the bottom of the fixed beam, the clamping strip is entirely embedded in the first clamping slot, and the clamping portion is embedded in the cavity surrounded by the clamping strip and the upper beam. This structure makes it easy to embed the clamping strip into the first clamping slot, and at the same time, after the clamping strip is embedded, the upper beam and the fixed beam are mutually clamped and supported, thereby improving the stability of the rolling shutter after installation.

[0017] In the above-mentioned rolling shutter installation structure, the top of the upper beam has a support strip, and the bottom of the fixed beam has a support surface. When the upper beam is fixed to the bottom of the fixed beam, the support strip is pressed against the support surface or there is a gap between the support strip and the support surface. This structure makes it difficult for the upper beam and the fixed beam to deflect and move relative to each other after being connected, further improving the stability of the connection between the upper beam and the fixed beam, thereby improving the stability of the rolling shutter after installation.

[0018] In the above-mentioned roller blind installation structure, a protruding placement strip in the shape of an angle iron is fixedly connected to the fixed beam, and a placement groove is formed between the placement strip and the fixed beam. The placement groove can be used to place objects or to cooperate with other components for use.

[0019] Compared with the prior art, the roller blind installation structure provided by the present invention has the following advantages:

[0020] 1. When installing this roller shutter, no screws or drilling are required, and no prior customization is required. As long as the fixed beam is pre-installed, it can be installed at any time when needed, which is convenient to use.

[0021] 2. This roller shutter is embedded and positioned by means of snap-in positioning, combined with the roller shutter's own gravity and the structure of the hanger, so that the roller shutter is automatically snap-in positioned after being connected to the bottom of the fixed beam. It is easy to install. When disassembling, you only need to push the roller shutter in the set direction to detach the hanger, which is easy to disassemble.

[0022] 3. The hanging parts of this roller shutter can slide freely, and the appropriate position can be selected according to actual needs, so as to further improve the stability of the connection between the upper beam and the fixed beam and improve the stability of the roller shutter installation.

[0030] The bottom of the fixed beam 3 has a first card slot 5 and a second card slot 6 which are recessed. The first card slot 5 and the second card slot 6 are both in the shape of long strips. The cross-sections of the first card slot 5 and the second card slot 6 are both in the shape of angle irons. The opening of the first card slot 5 has a protruding card connection portion 51. The setting of the card connection portion 51 makes the width of the opening of the first card slot 5 smaller than the width of the bottom of the slot. The opening of the second card slot 6 has a protruding hanging portion 62. The hanging portion 62 has an inclined hanging surface 61. The setting of the hanging portion 62 makes the width of the opening of the second card slot 6 smaller than the width of the bottom of the slot.

[0031] The upper beam 2 is provided with a protruding snap-in strip 7, a snap-in sheet 8 and a recessed third snap-in slot 9, the snap-in strip 7, the snap-in sheet 8 and the third snap-in slot 9 are all in the shape of long strips, the cross section of the snap-in strip 7 is in the shape of an angle iron, the snap-in sheet 8 is in the shape of a sheet, and the third snap-in slot 9 is provided with an inclined lifting surface 91. The hanger 4 includes a main body 41 in the shape of a flat plate, one end of the main body 41 is bent toward one side to form a hanging strip 42, and the other end of the main body 41 is bent toward the other side to form a lifting strip 43, the hanging strip 42 and the lifting strip 43 are both in the shape of long strips, the angle between the hanging strip 42 and the main body 41 is an acute angle, and the angle between the lifting strip 43 and the main body 41 is an acute angle.

[0032] When the upper beam 2 is fixed to the bottom of the fixed beam 3, the top of the upper beam 2 has abutment strip 21, and the bottom of the fixed beam 3 has abutment surface 31. In this embodiment, there is a gap between the abutment strip 21 and the abutment surface 31, and the gap can be 1mm. In actual production, the abutment strip 21 can be attached to the abutment surface 31. Figure 4 As shown, the clamping strip 7 is entirely embedded in the first clamping slot 5, and the clamping portion 51 is embedded in the cavity surrounded by the clamping strip 7 and the upper beam 2, so that the upper beam 2 and the fixed beam 3 are clamped.
