Description

Technical Field

[0001] This utility model relates to the technical field of mosquito net support components, specifically a mosquito net support tee. Background Technology

[0002] A mosquito net frame tee connector is an accessory used to connect three frames together. The three frames are threaded through the three connectors of the frame, securing them together to form a stable structure. Currently available mosquito net frame tees have locking ribs in the connectors, and the front end of the fitting has a notch. The fitting is inserted into the tee, where the locking rib engages with the notch, opening the notch to create a shape that is wider on the inside and narrower on the outside, making the fitting less likely to detach. However, this locking method makes disassembling the mosquito net frame tee and fitting inconvenient, and the tee is easily damaged during disassembly.

[0003] The relevant reference CN220777932U discloses a T-joint assembly for a mosquito net frame, which has a fixed sleeve and a movable sleeve. The movable sleeve is rotatably connected to the fixed sleeve via an ear plate. The movable sleeve can be flipped, but a protrusion is formed on the circumferential surface of one end of the fitting, and the protrusion is embedded in the receiving groove of the fixed sleeve and the movable sleeve. The T-joint assembly does not need to be disassembled from the fitting. However, it is difficult to pull the fitting out of the T-joint, and when the fitting needs to be replaced, the T-joint assembly must also be replaced, resulting in unnecessary waste.

[0035] like Figure 1As shown, the mosquito net frame tee includes a fixed sleeve 1 and a movable sleeve 2, which are used for inserting fittings into the mosquito net frame. The diameter of the fixed sleeve 1 is larger than that of the movable sleeve 2, providing a more stable support base for the mosquito net frame tee and making the mosquito net frame structure more stable. Two insertion blocks 4 are provided on the outer cylindrical surface of the closed end 3 of the fixed sleeve 1, and the insertion blocks 4 are spaced apart along the circumference of the fixed sleeve 1. A first ear plate 5 is fixedly provided below each insertion block 4. Each first ear plate 5 consists of two parallel ear plates. A second ear plate 6 is provided on the outer cylindrical surface of the movable sleeve 2. The second ear plate 6 is located between the two parallel ear plates. The movable sleeve 2 mainly consists of a plug-in part 7, a mounting part 8, and a notch part 9. One end of the plug-in part 7 is provided with an arc surface 10 and a plug interface 11. The arc surface 10 fits against the outer wall of the fixed sleeve 1, and the plug interface 11 cooperates with the plug-in block 4. The other end of the plug-in part 7 is fixedly provided with the mounting part 8, which is integrally connected with the notch part 9. The movable sleeve 2 is assembled together with the fastening sleeve 13 through the mounting part 8. The fastening sleeve 13 mainly consists of a connecting part 14, a tightening part 15, and a limiting part 16 arranged axially in sequence. The mounting part 8 and the connecting part 14 are locked together, the notch part 9 is tightened by the tightening part 15, and the limiting part 16 locks the protruding ring 19 on the assembled tube 18. This application utilizes the cooperation of the movable sleeve 2 with the installation part 8 and the fastening sleeve 13 to ensure that the assembly tube 18 will not loosen from the fastening sleeve 13. The assembly tube 18 can be firmly installed in the mosquito net frame tee. When it is necessary to disassemble the assembly tube 18, the user does not need to forcefully squeeze or twist it; disassembly can be completed simply by loosening the fastening sleeve 13. This greatly reduces the difficulty of operation, the risk of damage, and the cost of using the mosquito net frame tee. Users can easily install and disassemble the mosquito net frame without worrying about damage or loosening. At the same time, the stable structure also ensures the safety and comfort of using the mosquito net.

[0036] The second ear plate 6 is fastened to the first ear plate 5 with screws. Compared to existing mosquito net bracket tee connections where the ear plate on the movable sleeve 2 is connected to the fixed sleeve 1 via rivets, this screw-fastened connection simplifies installation and disassembly, and ensures a more secure and reliable connection. This design not only saves time and effort but also reduces operational difficulty and complexity. The second ear plate 6 has elastic ribs; when the movable sleeve 2 is perpendicular to the fixed sleeve 1, the elastic ribs press against the outer wall of the fixed sleeve 1, preventing the movable sleeve 2 from reversing.

[0037] like Figure 2 As shown, the mounting part 8 has external threads, and the connecting part 14 has internal threads; the two are locked together by the threads. The locking action of the external and internal threads ensures a firm and reliable connection between the mounting part 8 and the connecting part 14. This connection method has high strength and durability, capable of withstanding significant tensile and compressive forces, thus guaranteeing the stability and safety of the entire mosquito net support structure.

[0038] The notch 9 has four contraction surfaces 20. When the notch 9 on the movable sleeve 2 is pressed, the contraction surfaces 20 at the notch will form a tight contact with the assembled tube 18, thereby enhancing the stability of the connection.

[0039] like Figure 3 As shown, the inner wall of the tightening part 15 is provided with a ramp 12. The assembly tube 18 is tightened by pressing the notch 9 with the ramp 12. By pressing the notch 9 with the ramp 12, the tightening part 15 can more firmly fix the assembly tube 18 in the movable assembly tube 18, thereby improving the stability of the connection.

[0040] The limiting part 16 is provided with a limiting step 17. The limiting step 17 fits tightly with the protruding ring 19 on the assembly tube 18, effectively preventing the axial movement of the assembly tube 18 in the movable sleeve 2, thereby improving the stability of the connection.

[0041] like Figure 4 As shown, an assembly tube 18 is inserted through the fastening sleeve 13, and a protruding ring 19 is provided on the assembly tube 18 to cooperate with the limiting step 17. By inserting the assembly tube 18 into the fastening sleeve 13 and by using the cooperation between the protruding ring 19 and the limiting step 17, the assembly tube 18 can be effectively prevented from sliding off during the use of the mosquito net frame.

[0042] The assembled pipe 18 is composed of two pipe fittings. One pipe fitting has an internal thread at one end and a raised ring 19 at the other end. The other pipe fitting has a small diameter section 21 at one end, which is slightly smaller than the pipe fitting's diameter, and an external thread on the small diameter section. The other end also has a raised ring 19. The two pipe fittings are tightened together by the internal and external threads, making it easy for the assembled pipe 18 to be fitted with a fastening sleeve 13 with a limiting step 17.

[0043] In another embodiment, the outer wall of the fastening sleeve 13 is provided with arc-shaped raised ribs, which are axially distributed. The presence of the raised ribs provides additional gripping points during installation and removal, making it easier for the user to rotate the fastening sleeve 13 and helping to improve installation efficiency.

[0044] In use, the second ear plate 6 is screwed onto the first ear plate 5. The movable sleeve 2 is flipped over, and the insertion block 4 is inserted into the insertion interface 11 to lock the movable sleeve 2. The movable sleeve 2 is locked by the elastic convex rib to prevent it from reversing. The fastening sleeve 13 is fitted onto the assembly tube 18 with the convex ring 19. Then, the two assembly tubes 18 are screwed together to form a single pipe fitting. The limiting step 17 inside the fastening sleeve 13 engages the convex ring 19. The fastening sleeve 13 is tightened onto the mounting part 8 of the movable sleeve 2, causing the ramp 12 to press against the contraction surface 20 of the notch 9. The further inward the screwing, the tighter the contraction surface 20 is pressed, thus tightening the assembly tube 18. The bracket tee is equipped with three pipe fittings: a vertical pipe is inserted into the fixed sleeve 1, and the assembly tubes 18 are inserted into the other two movable sleeves 2. The three pipe fittings are located in two different directions and are used to erect the mosquito net bracket. The mosquito net bracket can be easily installed without worrying about damage or loosening. When it is necessary to disassemble the assembly tube 18, the user does not need to squeeze or twist the assembly tube 18 forcefully; the disassembly can be completed simply by loosening the fastening sleeve 13.
