Description

Technical Field

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

[0002] Mosquito nets are widely used in homes as an economical, environmentally friendly, and effective mosquito prevention tool. Traditional mosquito nets usually require a frame for support, but their large size conflicts with the need for a clean and aesthetically pleasing living space. Therefore, mosquito net frames with storage functions have emerged. They are designed to be neatly stored together with the mosquito net when not in use or during off-seasons, in order to save space and keep the indoor environment clean.

[0003] In existing designs of retractable mosquito net brackets, such as the "Mosquito Net Bracket with Convenient Folding" disclosed in announcement number "CN201509971U", two support rods are vertically installed in the box via a pivot. Although this design achieves the storage function, it still has shortcomings in actual use: its unfolding and folding process relies on the separate and independent rotation of the two support rods. This step-by-step operation makes the unfolding and folding process less smooth and efficient, and the operation steps are relatively cumbersome. Therefore, we propose a retractable mosquito net bracket with relatively higher convenience. Utility Model Content

[0004] In view of the problems existing in the prior art, this utility model discloses a retractable mosquito net bracket. The technical solution adopted is as follows: it includes a storage box, the front of which is provided with a door, and the top left and right ends of the door are respectively hinged to the top of the inner side of the storage box. The inside of the storage box is provided with symmetrical vertical shafts, and a bracket unit is rotatably installed on the outside of the shaft. The bracket unit includes a rotating arm, a rear connector, a telescopic rod, a front connector, and a U-shaped connecting rod. There are two rotating arms, one end of which is provided with a shaft hole, and the rotating arm is rotatably connected to the shaft through the shaft hole. A telescopic rod is provided at the front of the rotating arm. The fixed end and the telescopic end of the telescopic rod are respectively fixedly connected to the rear connector and the front connector. The telescopic rod is rotatably connected to the other end of the rotating arm through the rear connector. The telescopic rod is rotatably installed with the U-shaped connecting rod through the front connector. The bottom of the rotating arm is provided with a sleeve assembly that rotatably cooperates with the shaft.

[0005] As a preferred technical solution of this utility model, the sleeve assembly consists of a sleeve and diagonal bracing rods. The sleeve is fixedly installed at the bottom of the rotating arm, and the sleeve is respectively sleeved on the outside of the shaft. Diagonal bracing rods are welded to the bottom of the outer side of the sleeve, and the other end of the diagonal bracing rods is fixedly connected to the bottom center of the rotating arm.

[0006] As a preferred embodiment of this utility model, the screw holes at the upper and lower ends of the shaft are respectively threadedly connected to the connecting bolts on the outside of the storage box, and a support plate is integrally connected to the outside of the shaft, and the top surface of the support plate is in contact with the bottom of the sleeve.

[0007] As a preferred embodiment of this utility model, the rotational connection between the rear connector and the rotating arm is a damped rotational connection, and the rotational connection between the sleeve and the shaft is a damped rotational connection.

[0008] As a preferred embodiment of this utility model, it also includes mounting holes, of which four are provided and are respectively located at the four rear corners of the storage box.

[0009] As a preferred technical solution of this utility model, it also includes a mosquito net, wherein the mosquito net is attached to the outside of the rotating arm, the telescopic rod and the U-shaped connecting rod.

[0010] The beneficial effects of this utility model are as follows: By integrating the support unit into the storage box and optimizing its structure, the utility model utilizes the linkage design of the rotating arm, telescopic rod, and U-shaped connecting rod. Operating the U-shaped connecting rod simultaneously drives the entire support unit to unfold or retract, making the process simple and quick. This solves the problem of having to operate each support rod individually in the prior art. At the same time, the use of interference fit or tight fit damped rotation connection at key connection points ensures that the rotating arm and telescopic rod remain positioned after rotating to any angle, preventing them from rotating or folding arbitrarily due to the tension of the mosquito net or slight external force. This ensures the stability of the mosquito net in the unfolded state. In addition, the wall-mounted storage box makes full use of indoor space, making it very convenient to access and store.

[0017] Example 1

[0018] like Figures 1 to 5As shown, this utility model discloses a retractable mosquito net bracket. The technical solution includes a storage box 1, with a door 2 on the front side of the storage box 1. The top left and right ends of the door 2 are respectively hinged to the top inner side of the storage box 1 via hinges 6. Inside the storage box 1, symmetrical vertical shafts 3 are arranged on the left and right sides. A bracket unit 5 is rotatably mounted on the outer side of the shafts 3. The bracket unit 5 includes a rotating arm 51, a rear connector 52, a telescopic rod 53, a front connector 54, and a U-shaped connecting rod 55. Two rotating arms 51 are provided, each with a shaft hole at one end, and the rotating arms 51 are rotatably connected to the shafts 3 via the shaft holes. A telescopic rod 53 is respectively arranged in front of the rotating arms 51, with the fixed end and telescopic end of the telescopic rod 53 respectively... The storage box 1 is fixedly connected to a rear connector 52 and a front connector 54. A telescopic rod 53 is rotatably connected to the other end of a rotating arm 51 via the rear connector 52. A U-shaped connecting rod 55 is rotatably mounted on the telescopic rod 53 via the front connector 54. By pulling the U-shaped connecting rod 55 outward, the U-shaped connecting rod 55 drives the telescopic rod 53 to rotate outward via the front connector 54. Simultaneously, the rear end of the telescopic rod 53 drives the rotating arm 51 to rotate outward via the rear connector 52 until the rotating arm 51 and the telescopic rod 53 are fully extended. The storage box 1 also includes a mosquito net 11, which is attached to the outside of the rotating arm 51, the telescopic rod 53, and the U-shaped connecting rod 55 using straps or Velcro. 3 and the outer side of the U-shaped connecting rod 55 form a complete mosquito-proof space. The rotational connection between the rear connector 52 and the rotating arm 51 is a damped rotational connection, and the rotational connection between the sleeve 9 and the shaft 3 is a damped rotational connection. In this embodiment, the damped rotational connection is achieved in the following way: at the hinge axis between the rear connector 52 and the rotating arm 51, and between the sleeve 9 and the shaft 3, an interference fit or a tight fit is used to achieve damped rotation by relying on friction. This allows the rotating arm 51 and the telescopic rod 53 to remain positioned after rotating to any angle, and will not rotate or fold arbitrarily due to the tension of the mosquito net or slight external force, thereby ensuring the shape stability of the mosquito net in the unfolded state. The bottom of the rotating arm 51 is respectively provided with a sleeve that rotates with the shaft 3. The sleeve assembly consists of a sleeve 9 and diagonal braces 10. The sleeve 9 is fixedly installed at the bottom of the rotating arm 51, and is also sleeved on the outside of the shaft 3. Diagonal braces 10 are welded to the bottom of the outer side of the sleeve 9, and the other end of the diagonal braces 10 is fixedly connected to the center of the bottom of the rotating arm 51. The diagonal braces 10 greatly enhance the structural strength and stability of the connection node between the rotating arm 51 and the sleeve 9, making it less prone to bending or damage when bearing the weight of the mosquito net. The screw holes at the upper and lower ends of the shaft 3 are threadedly connected to the connecting bolts 4 on the outside of the storage box 1. Support plates 8 are integrally connected to the outside of the shaft 3, and the top surface of the support plates 8 is in movable contact with the bottom of the sleeve 9. The shaft 3 can be fixed by tightening the connecting bolts 4.During disassembly, the shaft 3 and bracket unit 5 can be removed together by unscrewing the bolts, facilitating maintenance. It also includes four mounting holes 7, located at the four rear corners of the storage box 1. These mounting holes 7 allow screws or other fasteners to be used to securely mount the entire storage box 1 to a wall, cabinet, or specific bracket, achieving wall-mounted installation.

[0019] The working principle of this utility model is as follows: In use, the storage box 1 is fixed to the bedroom wall or other suitable area. Then, the box door 2 is opened. By pulling the U-shaped connecting rod 55 outwards, the U-shaped connecting rod 55 drives the telescopic rod 53 to rotate outwards via the front connecting piece 54. Simultaneously, the rear end of the telescopic rod 53 drives the rotating arm 51 to rotate outwards from the storage box 1 via the rear connecting piece 52, until the rotating arm 51 and the telescopic rod 53 are fully extended. An interference fit or a tight fit is used at the hinge joint between the rear connecting piece 52 and the rotating arm 51, and between the sleeve 9 and the shaft 3, relying on friction to achieve resistance. The rotating arm 51 and telescopic rod 53 can remain positioned after rotating to any angle, preventing them from rotating or folding arbitrarily due to the tension of the mosquito net or slight external force, thus ensuring the stability of the mosquito net in its unfolded state. Subsequently, the mosquito net 11 is fixed to the outside of the rotating arm 51, telescopic rod 53, and U-shaped connecting rod 55 using straps or Velcro, forming a complete mosquito-proof space. When storing the support unit 5 and mosquito net 11, the telescopic rod 53 is adjusted to its shortest length, and by pushing the U-shaped connecting rod 55 inward, the rotating arm 51 and telescopic rod 53 fold inward, as shown. Figure 3 As shown, continue until the support unit 5 is completely retracted into the storage box 1, then organize the mosquito net 11 and store it in the storage box 1. Finally, close the box door 2 to complete the storage.
