Description

Technical Field

[0001] The utility model mainly relates to the technical field of blinds, and specifically relates to an automatically opening and closing blind. Background Technique

[0002] A blind, also known as a louver curtain, is a form of window in which several strip-shaped materials (such as wooden strips, aluminum alloys, glass, etc.) are arranged in parallel, and the light entering is controlled by rotating or adjusting the angle of the louvers. Its original style can be traced back to the vertical lattice windows and horizontal lattice windows in ancient Chinese architecture, and the horizontal lattice window is an early form of the blind.

[0003] An automatically opening and closing blind provided according to the application number CN201921525887.0 includes an upper fixed frame, a frame, a sealing strip, a movable mechanism, an automatic switch device, a sealing buckle cover and a lower fixed frame. This device adopts an automatic switch device, which effectively eliminates the cumbersome manual operation, and the screw drive has high stability, and the opening and closing degree of the blind is easy to control; this device adopts a movable mechanism. When the blind is closed, the movable rod moves upward, and drives the blades to flip through the connecting piece, realizing the closing of the blades; this device adopts blades and waterproof rubber pads, making the closing effect more tight. With the cooperation of the sealing strip and the sealing buckle cover, the sealing performance of the blind is strengthened, and there will be no water seepage due to rain during rainy days.

[0004] In the above device, the driving method is easy to occupy space during actual installation and use, making the overall blind overly cumbersome and unsightly. In addition, the blind is installed in a light-exposed position, and the provided sealing strip is prone to aging and falling off during long-term use, affecting the use. Content of the Utility Model

[0005] Based on this, the purpose of the present utility model is to provide an automatically opening and closing blind to solve the technical problems raised in the above background technique.

[0006] To achieve the above purpose, the present utility model provides the following technical solution:

[0007] An automatically opening and closing blind, including a blind body, the blind body includes symmetrically arranged side installation frames, a plurality of blades arranged in sequence from top to bottom on one side of the side installation frames, a tension assembly arranged at the top of the side installation frames, and a counterweight round rod at the bottom of the blades at the bottom of the side installation frames.

[0008] Preferably, the side installation frame is in a T shape, and a linear long groove perpendicular to the top of the side installation frame is embedded on one side of the side installation frame.

[0009] Preferably, an arc-shaped protrusion is provided at the top of one side of the blade, an arc-shaped groove is provided at the bottom of the other side of the blade, limiting shaft rods are symmetrically provided at both ends of the blade, and connecting rods are provided on one side of both ends of the blade and located at the side of the limiting shaft rods.

[0010] Preferably, the tension assembly is composed of limiting blocks symmetrically provided at the top of the side mounting frame, a motor symmetrically provided at the top of the side mounting frame and located on one side of the limiting blocks, a roller shaft provided between the two limiting blocks, a rope wound around the side wall of the roller shaft, and a pull rod provided at the bottom of the rope.

[0011] Preferably, the arc-shaped protrusion and the arc-shaped groove are arranged correspondingly and can be mutually attached; the limiting shaft rod is embedded in the side wall of the side mounting frame, the connecting rod is located on one side of the side mounting frame, and the connecting rods are arranged staggeredly from top to bottom.

[0012] Preferably, the execution ends of the two motors are connected to both ends of the roller shaft, and the pull rod is connected to the tops of the connecting rods at both ends of the blade located at the top of the side mounting frame.

[0013] Preferably, the blade is provided with a hollow inner cavity.

[0014] In summary, the technical solution mainly has the following beneficial effects:

[0015] In the present utility model, compared with the prior art of Xiao Education, the use of the embedded threaded screw method is abandoned, avoiding the problem that the transmission resistance of the screw and nut of the shutter becomes larger due to factors such as rust and dust accumulation during long-term use, which affects the use. Instead, the blades are connected in series by a connecting rod method. By offsetting the center position of the limiting shaft rod and designing a counterweight round rod on the blade, it can naturally fall and close without applying force to the blade; when it needs to be opened or closed, due to the short transmission process of the tension assembly, the use of the tension assembly can quickly open the shutter in response, and the whole device is more energy-saving and convenient to use.

[0016] Secondly, the structure of the blade is optimized, so that when the shutter is closed, the blades are mutually attached, better blocking light and dust. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Embodiment

[0026] As shown in Figure 1 , 4 , 5, and 6, it includes a shutter body 10. The shutter body 10 includes symmetrically arranged side mounting frames 11, a plurality of blades 12 arranged in sequence from top to bottom on one side of the side mounting frame 11, and a counterweight round rod 14 at the bottom of the blade 12 at the bottom of the side mounting frame 11; an arc-shaped protrusion 121 at the top of one side of the blade 12, an arc-shaped groove 122 at the bottom of the other side of the blade 12, symmetric limit shaft rods 123 at both ends of the blade 12, and connecting rods 124 at both ends of the blade 12 and on one side of the limit shaft rods 123; the arc-shaped protrusion 121 and the arc-shaped groove 122 are correspondingly arranged and can be mutually attached; the limit shaft rods 123 are on the side wall of the side mounting frame 11.

[0027] It should be noted that in this embodiment, when there is no force to pull the blade 12, driven by the self-weight of the counterweight round rod 14 at the bottom of the blade 12 at the bottom of the side mounting frame 11, the bottommost blade 12 rotates counterclockwise with the limit shaft rods 123 at both ends as the rotation axis. When the arc-shaped protrusion 121 at the top of one side of the blade 12 touches the arc-shaped groove 122 at the bottom of the adjacent upper blade 12, the rotation naturally stops;

[0028] At this time, the surfaces of the arc-shaped protrusion 121 and the arc-shaped groove 122 are mutually attached.

[0029] As shown in Figure 1 , 3As shown in the figure, the tension assembly 13 is located at the top of the side mounting frame 11. The tension assembly 13 is composed of a limit block 131 symmetrically located at the top of the side mounting frame 11, a motor 132 symmetrically located at the top of the side mounting frame 11 and on one side of the limit block 131, a roller shaft 133 between the two limit blocks 131, a rope 134 wound around the side wall of the roller shaft 133, and a pull rod 135 at the bottom of the rope 134; the connecting rod 124 is located on one side of the side mounting frame 11, and the connecting rods 124 are arranged in a staggered manner from top to bottom; the blade 12 is hollow inside.

[0030] It should be noted that in this embodiment, when the motor 132 at the top of the side mounting frame 11 works, the execution end of the motor 132 drives the roller shaft 133 to rotate. The rotation of the roller shaft 133 drives the rope 134 wound around its outer wall to wind and retract. The pull rod 135 at the bottom of the rope 134 moves upward, driving the blade 12 at the top of the side mounting frame 11 to rotate. Among them, the connecting rods 124 are staggered from top to bottom at both ends of all the blades 12, and all the blades 12 are hollow inside, further reducing their own weight. Finally, all the blades 12 can be easily lifted and opened and closed.

[0031] As Figure 1 、 2 shown in the figure, the side mounting frame 11 is in a T shape. A linear long groove 111 perpendicular to the top of the side mounting frame 11 is embedded on one side of the side mounting frame 11. The execution ends of the two motors 132 are connected to both ends of the roller shaft 133, and the pull rod 135 is connected to the top of the connecting rods 124 at both ends of the blade 12 at the top of the side mounting frame 11.

[0032] It should be noted that in this embodiment, since the rotation process of the blade 12 is small, the natural response of the shutter opening is rapid. Secondly, the linear long groove 111 can protect the connecting rods 124 at both ends of the blade 12 from being damaged during use.

[0033] The working principle of the present utility model is as follows:

[0034] When there is no force pulling the blade 12, driven by the self-weight of the counterweight round rod 14 at the bottom of the blade 12 at the bottom of the side mounting frame 11, the bottommost blade 12 rotates counterclockwise with the limit shaft rods 123 at both ends as the rotation axis. When the arc-shaped protrusion 121 at the top of one side of the blade 12 touches the arc-shaped groove 122 at the bottom of the other side of the adjacent upper blade 12, the rotation naturally stops;

[0035] At this time, the surfaces of the arc-shaped protrusion 121 and the arc-shaped groove 122 are mutually attached, which can better block light and dust;

[0036] When the shutter needs to be opened, the motor 132 at the top of the side mounting frame 11 operates. The execution end of the motor 132 drives the roller shaft 133 to rotate. The rotation of the roller shaft 133 drives the rope 134 on its outer wall to wind and retract. The pull rod 135 at the bottom of the rope 134 moves upward, driving the blade 12 at the top of the side mounting frame 11 to rotate. Among them, the connecting rods 124 are staggered from top to bottom at both ends of all the blades 12, and all the blades 12 are hollow inside, further reducing their own weight, and finally enabling all the blades 12 to be easily lifted and opened and closed;

[0037] Because the rotation process of the blade 12 is small, the opening of the shutter responds quickly naturally. Secondly, the linear long groove 111 can protect the connecting rods 124 at both ends of the blade 12 to prevent them from being damaged during use.

[0038] The above embodiments are only used to illustrate the technical idea of the present invention, and the protection scope of the present invention cannot be limited thereby. Any modification made on the basis of the technical solution according to the technical idea proposed by the present invention falls within the protection scope of the present invention.
