Description

Technical Field

[0001] This utility model relates to the field of curtain technology, specifically to a heat-insulating curtain. Background Technology

[0002] As part of home furnishings, curtains have evolved beyond their initial functions of decoration and privacy protection as people's living standards and consumption concepts have improved year by year. Their functional roles have been gradually developed and are gaining increasing recognition. Among these, heat insulation can effectively save energy, reduce outdoor high-temperature radiation into the room during summer, and increase indoor comfort.

[0003] Common curtains slide left and right, while some are pulled by chains, which are the two most common ways to open curtains. Of course, there are also electrically driven curtains, but when electrically driven curtains are pulled down manually, the shaft can easily cause the motor output to reverse, which can damage the motor. At the same time, if the dust on the surface of the curtain is not cleaned during the rolling up or lowering process, dust will accumulate on the surface of the curtain. Utility Model Content

[0004] Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a heat-insulating curtain that offers advantages such as motor protection and curtain cleaning, thus solving the aforementioned problems.

[0006] (II) Technical Solution

[0012] Preferably, both sides of the curtain are coated with a heat insulation layer, the curtain is made of a transparent film, and the curtain is slidably connected to the two side walls of the window frame by counterweights.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a heat-insulating curtain with the following beneficial effects:

[0015] 1. When this heat-insulating curtain is manually pulled down, the curtain fabric rotates along with the pivot. One end of the pivot is inserted into the connecting assembly, and the other end is rotatably connected to the shaft seat. The rotation of the pivot causes the slot and the locking head to press against each other, and then the pivot and the shaft sleeve slip off each other, thus ensuring that the output end of the motor reducer does not rotate with the pivot and preventing damage to the motor reducer. During normal electric control of the curtain, spring A pushes the locking head into the slot, locking the shaft sleeve and the pivot together. Then, the motor reducer rotates the connecting assembly and the pivot, thereby achieving the rolling up or lowering of the curtain fabric.

[0016] 2. In this heat-insulating curtain, the circular plate is pushed against the side wall of the support by spring B to prevent the wiping strips from excessively squeezing the curtain fabric, which would prevent the curtain from being able to be rolled up or down. When the curtain fabric is rolled up by the motor reducer, the wiping strips on both sides will clean the surface of the curtain fabric. Conversely, when the curtain fabric is manually pulled down, the wiping strips on both sides will clean the surface of the curtain fabric again. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1, please refer to Figure 1-3 A heat-insulating curtain includes a window frame 1, a curtain 2 movably installed inside the window frame 1, both sides of the curtain 2 are coated with a heat-insulating layer, the curtain 2 is made of transparent film, and a counterweight strip 3 is fixedly installed at the bottom of the curtain 2. The curtain 2 is slidably connected to the two side walls of the window frame 1 through the counterweight strip 3.

[0027] Please see Figure 4-5The top of the curtain 2 is fixedly installed on the outside of the rotating shaft 4. A side plate 5 is fixedly installed on the outside of the rotating shaft 4. One end of the rotating shaft 4 is movably installed on the inner wall of the window frame 1 through the shaft seat 6. A connecting component 7 is movably installed on the other end of the rotating shaft 4. The side of the connecting component 7 is fixedly installed on the output end of the motor reducer 8. When the motor reducer 8 rotates with the connecting component 7 and the rotating shaft 4, the curtain 2 can be electrically rolled up. On both sides of the curtain 2 and on the inner wall of the window frame 1, symmetrically arranged dust removal components 9 are provided. When the curtain 2 is electrically rolled up or manually pulled down, the dust removal components 9 can perform dust removal on both sides of the curtain 2.

[0028] Please see Figure 6 The connecting component 7 includes a bushing 71, with threaded holes 72 at both the top and bottom of the bushing 71. A threaded plug 73 is threadedly connected inside the threaded hole 72. A spring A74 is fixedly installed on the side of the threaded plug 73. A limit plate 75 is fixedly installed on the other end of the spring A74. A chuck 76 is fixedly installed on the side of the limit plate 75. A groove 77 corresponding to the chuck 76 is opened on the outer side of one end of the rotating shaft 4.

[0029] Please see Figure 6 The side of the bushing 71 is fixedly installed to the output end of the motor reducer 8, and the other side of the bushing 71 has a groove corresponding to the rotating shaft 4. Several slots 77 are arranged in a ring, and the end of the locking head 76 inserted into the slot 77 is hemispherical. The bushing 71 is movably engaged with the rotating shaft 4 through a threaded plug 73, a spring A74, the locking head 76, and the slots 77. When the spring A74 pushes the locking head 76 into the slot 77, the rotating shaft 4 and the bushing 71 are locked together. Then, the motor reducer 8 will drive the bushing 71 and the rotating shaft 4 to rotate synchronously, thereby achieving the winding and unwinding of the curtain fabric 2.

[0030] Example 2, please refer to Figure 7 Based on Embodiment 1, a dust removal component 9 is added. The dust removal component 9 includes two wiping strips 91, located on both sides of the curtain 2. A sliding rod 92 is fixedly installed on the side of the wiping strip 91, and the sliding rod 92 is inserted into the interior of the support 93. The support 93 is fixedly installed on the inner wall of the window frame 1. A circular plate 94 is fixedly installed on the outer side of the sliding rod 92, and a spring B95 is fitted on the outer side of the sliding rod 92 and on the side of the circular plate 94. The spring B95 can push the circular plate 94 against the side wall of the support 93, so that the wiping strips 91 on both sides can fit against the two sides of the curtain 2.

[0031] After the dust removal component 9 is installed, the curtain 2 needs to be manually removed; when recycling the curtain 2, it can also be electronically controlled to rewind; at the same time, the curtain 2 will also be cleaned of dust by the wiping strip 91.

[0032] Working principle: When the curtain is pulled down manually, the curtain 2 rotates with the shaft 4. One end of the shaft 4 is inserted into the connecting component 7, and the other end of the shaft 4 is rotatably connected to the bearing 6. The rotation of the shaft 4 causes the slot 77 and the clamp 76 to squeeze against each other, and then the shaft 4 and the bushing 71 slip off each other, thus ensuring that the output end of the motor reducer 8 will not rotate with the shaft 4, and ensuring that the motor reducer 8 will not be damaged.

[0033] When the curtain is in normal electric control mode, the spring A74 pushes the clip 76 into the slot 77 to lock the bushing 71 and the rotating shaft 4 together. Then, the motor reducer 8 drives the connecting component 7 and the rotating shaft 4 to rotate, thereby rolling up or lowering the curtain 2.

[0034] The circular plate 94 is pushed against the side wall of the support 93 by the spring B95 to prevent the wiping strip 91 from excessively squeezing the curtain 2, which would prevent the curtain 2 from being retracted or extended. When the curtain 2 is rolled up by the motor reducer 8, the wiping strips 91 on both sides will clean the surface of the curtain 2. Conversely, when the curtain 2 is manually pulled down, the wiping strips 91 on both sides will clean the surface of the curtain 2 again.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
