Abstract
Description
Technical Field
[0001] This utility model relates to the field of tarpaulin technology, specifically a tarpaulin deployment and retraction device. Background Technology
[0002] A canopy tarpaulin retraction device is a mechanical device used to control and operate the retraction and deployment of the shading fabric of a canopy (also known as an outdoor shading tarpaulin). This device is designed to simplify the operation of the canopy and improve its functionality, allowing the shading fabric to be easily deployed and retracted to adapt to different weather conditions and usage needs.
[0003] Chinese utility model patent CN213038706U discloses a canopy fabric retraction device and a canopy. Although the canopy fabric can be tightened and retracted simply by having a motor drive the roller to rotate forward and backward and cooperate with a stop component to lift or press it on the guide rail, the structure is simple. However, this canopy fabric retraction device has the disadvantages of requiring a motor to drive it, resulting in high manufacturing costs. Due to the weight of the motor, it is not very portable. At the same time, it cannot clean the surface of the canopy fabric, which may damage the fabric. Utility Model Content

Detailed Implementation
[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Example
[0025] Please see Figures 1 to 6 This utility model provides a technical solution: a canopy tarpaulin deployment and retraction device, including a housing 1 and a baffle 8. A fabric retraction disc 4 is rotatably connected inside the housing 1, and a tarpaulin 5 is movably connected to the outer surface of the fabric retraction disc 4. One end of the tarpaulin 5 is provided with a T-shaped retaining strip 501. One end of the baffle 8 is fixedly connected with a retaining strip block 9. A retaining strip retaining groove 801 is opened inside the baffle 8. The cross-sectional shape and size of the retaining strip retaining groove 801 correspond to the cross-sectional shape and size of the T-shaped retaining strip 501. The T-shaped retaining strip 501 is slidably connected inside the retaining strip retaining groove 801. A baffle 11 is fixedly installed on one side of the housing 1. A mud scraping groove 111 is opened on the outer surface of the baffle 11.
[0026] Specifically, through the cooperation of the baffle 8 and the outer shell 1, the outer shell 1 and the baffle 8 can be fixed by the outer shell fixing plate 3 and the baffle fixing plate 10 during use, thereby completing the construction of the tarpaulin 5. At the same time, after the tarpaulin 5 is retracted, the baffle 8 can prevent the tarpaulin 5 from being rolled into the outer shell 1, thus making it easier and faster to install the tarpaulin 5 and facilitate subsequent use, thereby improving the convenience of the device. Through the setting of the mud scraper 2, surface water stains and foreign objects can be scraped off when the tarpaulin 5 is retracted. Through the setting of the T-shaped clip 501, the tarpaulin retraction device can quickly assemble the baffle 8.
[0027] Please see Figures 1 to 6 There are several mud scraping grooves 111, which are symmetrically and evenly distributed on the upper and lower sides of the baffle 11. A mud scraper 2 is fixedly installed inside each mud scraper 111. The right end of the mud scraper 2, where it contacts the tarpaulin 5, has a beveled design. One end of the outer shell 1 has a threaded groove 102, and a threaded connector 6 is threadedly connected inside the threaded groove 102. A fabric take-up disc 4 is rotatably connected to one side of the threaded connector 6. A rotating shaft 7 is fixedly connected to one end of the fabric take-up disc 4, and a turntable is fixedly connected to one end of the rotating shaft 7. A rocker arm is fixedly connected to the outer surface of the tray, and a rotating sleeve is rotatably connected to the outer surface of the rocker arm. A positioning groove 101 is provided at the other end of the outer shell 1. A positioning block 401 is fixedly connected to the other end of the fabric receiving tray 4. The positioning block 401 is movably connected to the inside of the positioning groove 101. A tarpaulin slot 103 is provided inside the outer shell 1. The tarpaulin 5 is slidably connected to the inside of the tarpaulin slot 103. One end of the tarpaulin slot 103 is connected to the cavity where the fabric receiving tray 4 is located, and the other end of the tarpaulin slot 103 is connected to the inside of the baffle 11.
[0028] Specifically, the threaded connector 6 allows the tarpaulin retraction device to secure the fabric retraction disc 4, facilitating quick disassembly for subsequent maintenance and replacement. The combined use of the scraper 2 and baffle 11 ensures that during retraction, foreign objects and water stains on the inner and outer sides of the tarpaulin 5 are scraped away through the scraper groove 111 by the beveled front end of the scraper 2. This effectively removes foreign objects from the tarpaulin 5, preventing contamination and damage, while also ensuring the tarpaulin 5 remains flat during retraction. This guarantees the cleanliness and flatness of the tarpaulin 5 and extends the device's lifespan.
[0029] Please see Figures 1 to 3A housing fixing plate 3 is fixedly connected to one side of the housing 1. There are several housing fixing plates 3, which are evenly distributed on one side of the housing 1 in a linear array. A stop bar fixing plate 10 is fixedly connected to one side of the stop bar 8. There are several stop bar fixing plates 10, which are evenly distributed on one side of the stop bar 8 in a linear array.
[0030] Specifically, through the cooperation of the baffle 8 and the outer shell 1, the outer shell 1 and the baffle 8 can be fixed by the outer shell fixing plate 3 and the baffle fixing plate 10 during use, thereby completing the erection of the tarpaulin 5. At the same time, after the tarpaulin 5 is retracted, the baffle 8 can prevent the tarpaulin 5 from being rolled into the outer shell 1, thus making it easier and faster to install the tarpaulin 5 and facilitate subsequent use, thereby improving the convenience of the device.
[0031] In use, first pull out a portion of the tarpaulin 5 from the take-up tray 4, so that the tarpaulin 5 is inserted into the interior of the outer casing 1 along the tarpaulin slot 103. Simultaneously, push the take-up tray 4 until the positioning block 401 engages with the positioning groove 101 on the back of the outer casing 1. Then, the threaded connector 6, which is rotatably connected to the front of the take-up tray 4, is threaded through the threaded groove 102 on the front of the outer casing 1. After connection, simply stretch one end of the tarpaulin 5 and insert it into the stop bar slot 801 via the T-shaped clip 501 to complete the initial assembly of the take-up and release device. During use, simply fix both ends of the stop bar 8 with the stop bar fixing plate 10, then rotate the rotating shaft 7 using the rocker arm to rotate the take-up tray 4 and release the tarpaulin 5. Once the required size of the tarpaulin 5 is released, simply... The tarpaulin 5 is supported in the middle by a crossbeam frame. After adjusting the tarpaulin 5 to the appropriate size, the two ends of the outer shell 1 are fixed by the outer shell fixing plate 3 to complete the installation of the tarpaulin 5. After use, simply remove the fixing parts at the outer shell fixing plate 3 and the baffle fixing plate 10. Rotate the rotating shaft 7 with the rocker arm to drive the cloth take-up disc 4 to take up the cloth. During the cloth take-up process, when the tarpaulin 5 reaches the mud scraper 2, foreign objects and water stains on the inside and outside of the tarpaulin 5 will be scraped out from the mud scraper groove 111 due to the sloping design at the front end of the mud scraper 2, thus ensuring the cleanliness of the tarpaulin 5. When a part is damaged and needs to be replaced, simply remove the T-shaped clip 501 from the baffle slot 801, and then remove the cloth take-up disc 4 through the tarpaulin slot 103 and the threaded groove 102 for maintenance or replacement of the part.
