Description

Technical Field

[0001] This utility model relates to the field of Venetian blind technology, and in particular to an electrically adjustable proportional lifting Venetian blind. Background Technology

[0002] Venetian blinds are a type of curtain composed of multiple adjustable slats. By rotating the slats, light, ventilation, and privacy can be controlled, combining practicality and decoration.

[0003] As disclosed in announcement number CN222976734U, a Venetian blind lifting device includes a housing. A drive shaft is rotatably connected inside the housing. A guide wheel is fixedly connected to the outer surface of the drive shaft. A pull rope is driven by the outer surface of the guide wheel. A counterweight plate is fixedly connected to one end of the pull rope. A pressing component is fixedly installed on the top of the inner wall of the housing. A driven bevel gear is fixedly connected to the outer surface of the drive shaft. A motor is fixedly installed on one side of the housing. The advantages are: the motor drives the driven bevel gear to rotate through the driving bevel gear, causing one end of the pull rope to descend and the other end to rise, thus raising and lowering the Venetian blind. The transmission component of this design is very simple, resulting in low energy loss and achieving energy saving. Furthermore, the design of the counterweight plate further reduces the load on the motor, thus further improving energy efficiency. The simple structure also reduces costs, making it suitable for widespread adoption.

[0004] This patent allows for the raising and lowering of venetian blinds by pulling a rope, and also allows for the compression of the rope by a pressure roller. However, existing devices do not have the function of disassembly. Over time, the rope will wear out and cannot be disassembled and replaced, which will lead to the rope breaking and the transmission system becoming completely paralyzed. Utility Model Content

[0005] The purpose of this invention is to solve the problem that existing devices do not have the function of disassembly, but the pull rope will wear out after long-term use. The inability to disassemble and replace it will lead to the breakage of the pull rope and the complete paralysis of the transmission system.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an electrically adjustable proportional lifting venetian blind, comprising a housing, a motor connected to one side surface of the housing, and a convenient disassembly and assembly component connected to the front end surface of the housing near the motor. The convenient disassembly and assembly component includes a mounting groove, an mounting plate disposed inside the mounting groove, a handle connected to one side outer surface of the mounting plate, a slot formed on the surface of the handle, a fixing block connected to the surface of the housing near the handle, two sets of first springs connected inside the fixing block, push rods inserted into the interior of each of the two sets of first springs, handles connected to the rear ends of the two sets of push rods, push plates connected to the front ends of the two sets of push rods, and insert blocks connected to the surface of the push plates.

[0007] Furthermore, the surface of the insert block is provided with a bevel, and the position of the insert block and

[0008] The size matches the position and size of the card slot.

[0009] Furthermore, the insert block and the slot form an interlocking connection, and the upper and lower surfaces of the mounting plate are in contact with the inner wall of the mounting slot.

[0010] Furthermore, the mounting plate and the mounting groove form a sliding connection.

[0011] Furthermore, pressure detection components are connected to the inner top of both sides of the housing. The pressure detection components include two sets of sleeves, and the outer surfaces of the two sets of sleeves are connected to side lugs.

[0012] Furthermore, a bolt is inserted into the inside of the side ear, and a second spring is provided inside the sleeve, with a second spring connected to the bottom of the second spring.

[0013] Furthermore, a pressure wheel is connected to the bottom of the second spring, and an alarm is connected to the surface of the housing near the fixing block.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, the pull rope will wear out severely after long-term use. At this time, the plug block can be retracted by pulling the handle outward. Then, the handle can be pulled outward to slide the mounting plate for disassembly. After the pull rope is replaced, the mounting plate can be pushed into the mounting groove and automatically fixed by the plug block. This avoids the problem that the traditional shell cannot be disassembled, thus making it impossible to replace the pull rope, which can easily lead to severe wear and breakage of the pull rope. This improves the safety of the device during use.

[0016] 2. In this utility model, the compression of the lower pressure roller by the second spring can achieve the purpose of tension control. After long-term use, the second spring will experience elastic fatigue. The pressure sensor can detect the elastic force. When the elastic fatigue is serious, it can be used in conjunction with the alarm to achieve the effect of prompting, so as to avoid the reduction of elastic force causing insufficient pressure on the lower pressure roller and thus affecting the purpose of tension control.

Detailed Implementation

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1, as Figure 1 - Figure 3 As shown, this utility model provides an electrically adjustable proportional lifting venetian blind, including a housing 1. A motor 2 is connected to one side surface of the housing 1. A convenient disassembly and assembly component 3 is connected to the front surface of the housing 1 near the motor 2. The convenient disassembly and assembly component 3 includes a mounting groove 301, an mounting plate 302 is disposed inside the mounting groove 301, a handle 303 is connected to one side outer surface of the mounting plate 302, a slot 304 is formed on the surface of the handle 303, and a fixing block 305 is connected to the surface of the housing 1 near the handle 303. Two sets of first springs 305 are connected inside the fixing block 305. 6. Push rods 307 are inserted into the interior of both sets of first springs 306. Handles 308 are connected to the rear ends of the two sets of push rods 307. Push plates 309 are connected to the front ends of the two sets of push rods 307. Insert blocks 310 are connected to the surface of the push plates 309. The surface of the insert blocks 310 has bevels. The position and size of the insert blocks 310 match the position and size of the slots 304. The insert blocks 310 and the slots 304 form an insertion connection. The upper and lower surfaces of the mounting plate 302 are in contact with the inner wall of the mounting groove 301. The mounting plate 302 and the mounting groove 301 form a sliding connection.

[0025] The effect achieved in Embodiment 1 is that the pull rope will wear out severely after prolonged use, so it needs to be replaced regularly. When replacing it, the power to the motor 2 can be turned off, and then the handle 308 can be pulled outwards. This allows the handle 308 to drive the push plate 309 via the push rod 307 to press against the first spring 306, thereby causing the insert block 310 to be pulled out of the slot 304 of the handle 303. Then, pulling the handle 303 outwards allows the mounting plate 302 to slide out of the mounting groove 301. This completes the installation process. The mounting plate 302 can be removed so that the pull rope can be replaced. After replacement, the mounting plate 302 can be pushed into the mounting groove 301. When the angled opening of the insert block 310 is squeezed, it will automatically retract. After the mounting plate 302 is fully pushed into the mounting groove 301, the first spring 306 will push the push plate 309 to drive the insert block 310 into the slot 304 for fixing. This avoids the problem that the traditional housing 1 cannot be disassembled, thus making it impossible to replace the pull rope, which can easily lead to severe wear and breakage of the pull rope. This improves the safety of the device during use.

[0026] Example 2, as Figure 1 and Figure 4 As shown, pressure detection components 4 are connected to the inner top of both sides of the housing 1. The pressure detection components 4 include two sets of sleeves 401. The outer surfaces of the two sets of sleeves 401 are connected to side ears 402. Bolts 403 are inserted into the inside of the side ears 402. A second spring 404 is provided inside the sleeve 401. A second spring 404 is connected to the bottom of the second spring 404. A pressure roller 406 is connected to the bottom of the second spring 404. An alarm 407 is connected to the surface of the housing 1 near the fixing block 305.

[0027] The effect achieved in Embodiment 2 is that the compression of the lower pressure roller 406 by the second spring 404 can achieve the purpose of tension control. After long-term use, the second spring 404 will experience elastic fatigue. The pressure sensor 405 can monitor the elastic force. When the elastic fatigue is more serious, the compression of the pressure sensor 405 will be less than the set value. Then, an electrical signal can be sent to the alarm 407, causing the alarm 407 to sound automatically, so as to remind the operator to replace it and avoid the reduction of elastic force causing insufficient pressure on the lower pressure roller 406, which would affect the purpose of tension control.

[0028] Working principle: After prolonged use, the pull rope will wear out significantly. Pulling the handle 308 outwards will retract the insert block 310. Then, pulling the handle 303 outwards will slide the mounting plate 302 for disassembly. After replacing the pull rope, the mounting plate 302 is pushed into the mounting groove 301 and automatically fixed by the insert block 310. This avoids the problem of the traditional housing 1 being unable to be disassembled, thus preventing the pull rope from being replaced and easily leading to severe wear and breakage. This improves the safety of the device during use. The compression of the lower pressure wheel 406 by the second spring 404 achieves the purpose of tension control. With prolonged use, the second spring 404 may experience elastic fatigue. The pressure sensor 405 can detect the elasticity. When the elasticity fatigue is severe, the alarm 407 can provide a warning, preventing insufficient pressure on the lower pressure wheel 406 due to reduced elasticity, which would affect the purpose of tension control.

[0029] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
