Description

Technical Field

[0001] This utility model belongs to the field of sunshade curtain technology, and in particular relates to a sunshade curtain torsion spring anti-noise structure. Background Technology

[0002] Sunshades are used to effectively block sunlight from entering through the windshield, side windows, and rear windows of a car. Sunshades can be designed to fit the curvature of the windshield for different car models, and high-end sunshades can include automatic speed-regulating mechanisms.

[0003] Because the torsion spring is located inside the aluminum tube of the sunshade, when the torsion spring twists and turns, it scrapes against the aluminum tube, producing a sharp and piercing sound that can cause discomfort to the user. This is why conventional sunshade torsion springs and aluminum tubes are prone to producing harsh noises.

[0004] To address this issue, we propose a torsion spring structure for sunshades to prevent noise. Utility Model Content

[0005] The purpose of this invention is to solve the problem of harsh noise that easily occurs between the torsion spring and aluminum tube in conventional sunshade curtains, and to propose a noise-proof structure for the torsion spring of sunshade curtains.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A noise-reducing structure for a sunshade curtain torsion spring includes a threaded seat with a torsion spring fixedly connected to it. A threaded ring is threaded onto the lower part of the threaded seat, and a non-woven fabric tube is fitted onto the lower end of the threaded seat. The threaded ring presses against the upper end of the non-woven fabric tube, and the non-woven fabric tube is movably fitted around the torsion spring. First, the non-woven fabric tube is fitted onto the lower end of the threaded seat, then the threaded ring is fitted onto the torsion spring. The threaded ring is then tightened onto the lower part of the threaded seat, clamping and fixing the upper end of the non-woven fabric tube between the threaded seat and the lower part of the threaded ring. This keeps the non-woven fabric tube outside the torsion spring, preventing noise caused by friction between the torsion spring and the inside of the target aluminum tube.

[0008] Preferably, the threaded seat includes a knob, the lower end of which is fixedly connected to a threaded seat body, and the lower end of the threaded seat body is fixedly connected to a fixing plug. The nonwoven fabric tube is fitted onto the fixing plug, and then the threaded ring is tightened, so that the fixing plug is inserted inside the threaded ring and the nonwoven fabric tube, fixing the nonwoven fabric tube and facilitating the threaded seat to press against the inner wall of the nonwoven fabric tube.

[0009] Preferably, the threaded seat further includes a reinforcing ring, which is fixedly connected between the threaded seat body and the retaining plug. The reinforcing ring increases the firmness between the retaining plug and the threaded seat body.

[0010] Preferably, the knob has a first anti-slip texture on its outer surface. The first anti-slip texture increases the friction between the hand and the knob.

[0011] Preferably, the lower end of the fixing plug has a guide surface. The guide surface guides the fixing plug into the nonwoven fabric tube and the threaded ring, making it easier for the threaded seat and the threaded ring to clamp the nonwoven fabric tube.

[0012] Preferably, the threaded ring includes a threaded ring body and a pressure ring, with the pressure ring fixedly connected to the lower inner end of the threaded ring body. The threaded ring body and the pressure ring are fitted over the nonwoven fabric tube, and then the threaded ring body is threaded onto the threaded seat body, so that the fixing plug is inserted inside the nonwoven fabric tube inside the pressure ring, which facilitates the fixation of the upper part of the nonwoven fabric tube.

[0013] Preferably, the outer surface of the threaded ring body is provided with a second anti-slip texture. The second anti-slip texture increases the friction between the hand and the threaded ring.

[0014] Preferably, the toggle spring includes a mounting ring and a spring, with the lower end of the mounting ring fixedly connected to the upper end of the spring as a single unit. The spring provides toggle force to the mounting ring.

[0015] In summary, the technical effects and advantages of this utility model are as follows:

[0016] 1. First, put the non-woven fabric tube on the lower end of the threaded seat, then put the threaded ring on the outside of the spring, and then tighten the threaded ring on the lower part of the threaded seat. This clamps the lower part of the threaded seat and the threaded ring to fix the upper end of the non-woven fabric tube, keeping the non-woven fabric tube outside the spring. The non-woven fabric tube is used to block the spring from rubbing against the inside of the target aluminum tube, thus preventing noise.

[0017] 2. Place the non-woven fabric tube onto the fixing plug, and then tighten the threaded ring so that the fixing plug is inside the threaded ring and the non-woven fabric tube, thus fixing the non-woven fabric tube and making it easier for the threaded seat to press against the inner wall of the non-woven fabric tube.

[0018] 3. Use the guide surface to guide the fixing plug into the non-woven fabric tube and the threaded ring, so that the threaded seat and the threaded ring can clamp the non-woven fabric tube.

[0019] 4. Place the threaded ring and pressure ring over the nonwoven fabric tube, and then thread the threaded ring onto the threaded seat, so that the fixing plug is inside the nonwoven fabric tube inside the pressure ring, which facilitates fixing the upper part of the nonwoven fabric tube.
