Description

Technical Field

[0001] This utility model relates to the field of roller shutter door technology, specifically to a roller shutter door slide guide wheel. Background Technology

[0002] Roller shutter guide wheels are a type of support device used for opening and closing roller shutters. Nowadays, roller shutters are becoming increasingly widely used. When in use, roller shutters consist of multiple articulated door panels connected together and rotating up and down within a fixed track around a central roller at the top of the door to facilitate opening and closing. Roller shutter guide wheels are used in the operation of roller shutters.

[0003] The prior art patent document with publication number CN211900415U provides: a roller shutter door slide guide wheel, including a slide guide wheel body. The anti-slip multi-roller guide wheel mechanism can increase the smoothness of the slide, making it easier for the roller shutter door to open and close, and reducing the likelihood of slippage. It slides through bearings, and the reinforcing ribs increase the strength of the anti-slip multi-roller guide wheel mechanism. The wear-resistant ring has good wear resistance, increasing the service life of the anti-slip multi-roller guide wheel mechanism. The anti-slip pad has a good anti-slip effect, reducing the likelihood of slippage in the roller shutter door, increasing the stability of the roller shutter door operation, and facilitating better operation. The use of the anti-slip multi-roller guide wheel mechanism and the sliding wheel double roller system increases the smoothness of the slide.

[0004] Although the device has many beneficial effects, the following problems still exist: during the use of the device, the socket of the guide wheel is not easy to adapt to guide supports of different sizes, and the installation is not stable enough; secondly, the device has poor sound insulation effect during use, and generates a lot of noise when the roller shutter door is in use, which needs to be improved. In view of this, we propose a roller shutter door track guide wheel. Utility Model Content

[0033] The embodiments of this utility model will now be described in further detail with reference to the accompanying drawings.

[0034] This utility model provides an overall structural diagram of an embodiment of a roller shutter door slide guide wheel, including:

[0035] Please see Figures 1-5This embodiment of a roller shutter door guide wheel includes a guide rail 1. Limiting strips 2 are welded to both sides of the inner cavity of the guide rail 1. An installation assembly 3 is snapped onto the top of the guide rail 1. The installation assembly 3 includes a mounting bracket 301. A fixing plate 302 is welded to the bottom of the mounting bracket 301. Multiple screw holes 303 are formed on the side wall of the fixing plate 302. Slots 304 are formed on both sides of the mounting bracket 301. Receiving grooves 305 are formed on the side walls of both slots 304. Multiple springs 306 are fixed to the side walls of the receiving grooves 305. Abutment blocks 3 are fixed to the other ends of the multiple springs 306. 07. A guide wheel 4 is rotatably connected to the top of the inner cavity side wall of the mounting bracket 301. A sound insulation component 5 is bonded to the side wall of the guide rail 1. The movement of the roller shutter door panel is limited by the limiting strip 2. By installing the mounting bracket 301 in the required position, the top of the side wall of the guide rail 1 is inserted into the slot 304 to press the abutment block 307, causing the abutment block 307 to move into the receiving groove 305. The rebound force of the spring 306 drives the abutment block 307 to reset and press the guide rail 1, thereby making the installation of the guide wheel 4 more stable. The stability of the mounting bracket 301 is improved by screwing the bolt into the screw hole 303.

[0036] It is worth noting that, in order to prevent the slot 304 from rotating, the sound insulation component 5 specifically includes a foam board 501, a sound insulation board 502 is glued to the side wall of the foam board 501, and multiple mounting holes 503 are opened on the side wall of the sound insulation board 502. Sound-absorbing cotton columns 504 are clamped to the inner circumference of the multiple mounting holes 503. Adhesive strips 505 are glued to both sides of the sound insulation board 502. The foam board 501 and the sound insulation board 502 are glued together by the adhesive strips 505. The foam board 501 absorbs some noise, and the sound-absorbing cotton columns 504 are installed through the mounting holes 503. The sound insulation board 502 and the sound-absorbing cotton columns 504 isolate noise.

[0037] Next, in order to facilitate the installation of the mounting bracket 301, specifically, the bottom of the side wall of the abutment block 307 is inclined, and the size and position of the abutment block 307 match the size and position of the receiving groove 305. With the abutment block 307 having an inclined bottom, it is convenient to squeeze the abutment block 307 to move the abutment block 307 inward when the mounting bracket 301 is inserted into the top of the side wall of the guide rail 1.

[0038] Meanwhile, to enhance the sound insulation effect, the sound insulation board 502 is made of polyester fiber, and the sound-absorbing cotton column 504 is made of ultrafine glass wool. The porous structure of the sound insulation board 502 made of polyester fiber can effectively absorb sound waves and reduce the transmission of noise. Ultrafine glass wool is a thermal insulation material made of quartz sand, feldspar, sodium silicate, boric acid and other main raw materials. It has the characteristics of good formability, low bulk density, low thermal conductivity, good thermal insulation, good sound absorption performance, corrosion resistance and stable chemical properties.

[0039] Furthermore, in order to improve the rotational guiding effect of the guide wheel 4, specifically, an outer tube 6 is fixedly provided on the inner circumference of the guide wheel 4, and multiple needle rollers 7 are rotatably connected to the inner circumference of the outer tube 6. An inner tube 8 is provided on the inner circumference of the outer tube 6 and is rotatably connected to the needle rollers 7. The needle rollers 7 prevent the inner tube 8 from rotating with the outer tube 6, thereby improving stability.

[0040] It is worth noting that, in order to prevent the roller shutter door panel from slipping, specifically, the outer circumference of the guide wheel 4 is fixed with an anti-slip sleeve 9. The anti-slip sleeve 9 is made of nylon. The nylon anti-slip sleeve 9 is resistant to high temperature and corrosion, and increases the friction between the guide wheel 4 and the roller shutter door panel.

[0041] Finally, for guiding the roller shutter door panel, specifically, the two ends of the inner tube 8 are fixedly connected to the top of the side walls of the inner cavity of the mounting bracket 301, and the diameter of the anti-slip sleeve 9 is larger than the width of the mounting bracket 301. The anti-slip sleeve 9, with a diameter larger than the width of the mounting bracket 301, facilitates the guidance of the roller shutter door panel.

[0042] Combination Figures 1-5 The specific usage process of the roller shutter door guide wheel in this embodiment is as follows:

[0043] 1. According to the actual use, install the mounting bracket 301 in the required position, insert the top of the side wall of the guide rail 1 into the slot 304, and after the abutment block 307 is squeezed, it moves into the receiving groove 305. The rebound force of the spring 306 drives the abutment block 307 to return to the guide rail 1. Screw the bolt into the screw hole 303 to install the fixing plate 302, thereby fixing the position of the guide wheel 4.

[0044] 2: Attach foam board 501 and sound insulation board 502 to the side wall of guide rail 1 with adhesive strip 505, and insert sound-absorbing cotton column 504 into the mounting hole 503 to absorb and isolate noise.

[0045] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
