Description

Technical Field

[0001] This utility model relates to the technical field of hat support frames, specifically hat support frames. Background Technology

[0002] The main function of a hat support is to maintain the shape and appearance of a hat, preventing it from deforming or collapsing. Currently, the main types of hat supports on the market are listed below. Figure 1 As shown, it mainly includes two support bodies 1 and a bidirectional screw 2. The bidirectional screw 2 is used to drive the two support bodies 1 to extend and retract. In order to facilitate the rotation of the bidirectional screw 2, a vertical lever 3 is often fixed on the surface of the bidirectional screw 2, and the lever 3 is used to rotate it.

[0003] However, this method of use, especially after the support 1 is placed inside the hat, requires inserting your hand into the hat to turn the double-ended screw 2. This is not only inconvenient to turn, but also affects the cleanliness of the inside of the hat, especially when not wearing gloves. Therefore, we propose a hat support frame. Utility Model Content

[0004] One of the technical problems to be solved by this application is to propose a hat support frame structure that is easy to rotate to open the hat body.

[0005] To solve the above-mentioned technical problems, embodiments of this application provide a hat support frame, including a bidirectional screw and support bodies respectively threaded to the ends of the bidirectional screw. A reversing drive assembly is provided on the bidirectional screw, and a drive rod perpendicular to the bidirectional screw is rotatably connected to the reversing drive assembly.

[0006] In some embodiments, the reversing drive assembly includes a drive box rotatably mounted on a bidirectional screw, a bevel gear A fixed on the bidirectional screw is disposed inside the drive box, a drive rod passes through one side wall of the drive box and is rotatably connected to it, and a bevel gear B that meshes with the bevel gear A is fixed on the drive rod.

[0007] In some embodiments, a knob is fixed to one end of the drive rod located outside the drive box, and the side of the knob away from the drive box is a flat end face.

[0008] In some embodiments, a limiting guide rod is also provided between the two supports, the limiting guide rod passing through both supports and being fixedly connected to the drive box.

[0009] In some embodiments, a polygonal extension groove is formed at the end of the drive rod, a polygonal extension rod slides in the polygonal extension groove, the knob is fixed to the end of the polygonal extension rod, and a locking pin is threaded through the drive rod.

[0010] In some embodiments, the drive rod includes a fixed seat and a disassembly rod mounted on the drive box. The bevel gear B is mounted on the fixed seat. The fixed seat has a polygonal groove at its end, and the disassembly rod has a polygonal structure that matches the polygonal groove at its end.

[0011] In some embodiments, magnets are embedded in both the inner wall of the polygonal groove and the end of the disassembly rod, and the magnetic poles of the opposite faces of the magnets are opposite.

[0012] This utility model has at least the following beneficial effects:

[0013] This application adds a reversing drive assembly composed of bevel gears and a vertically positioned drive rod to the bidirectional screw, allowing users to easily control the opening and closing of the support body directly from outside the hat by rotating the drive rod without having to put their hands inside. This not only makes operation more convenient and labor-saving, but also effectively avoids contamination of the inside of the hat caused by hand contact, thereby effectively improving hygiene and user experience.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figures 2-3 As shown, this utility model provides a technical solution: a hat support frame, including a bidirectional screw 2 and a support body 1 threadedly connected to the ends of the bidirectional screw 2. The edges of the support body 1 are rounded to increase its bearing area, so as to avoid indentation caused by local contact pressure. A reversing drive assembly 4 is provided on the bidirectional screw 2, and a drive rod 5 perpendicular to the bidirectional screw 2 is rotatably connected to the reversing drive assembly 4.

[0023] Specifically, the reversing drive assembly 4 includes a drive box 41 rotatably mounted on the bidirectional screw 2. The drive box 41 is rotatably connected to the bidirectional screw 2 by a bearing. A limiting step is provided on the bidirectional screw 2 to contact and abut against the drive box 41 to limit the axial sliding of the drive box 41. A bevel gear A42 is provided inside the drive box 41 and fixed on the bidirectional screw 2. The drive rod 5 passes through one side wall of the drive box 41 and is rotatably connected to it by a bearing. Similarly, a limiting step is provided on the drive rod 5 to contact and abut against the drive box 41. A bevel gear B43 that meshes with the bevel gear A42 is fixed on the drive rod 5.

[0024] In this way, during use, the drive rod 5 can extend out of the cap body through the reversing drive of bevel gear A42 and bevel gear B43, making it easier to hold and more convenient to drive the rotation of the bidirectional screw 2. Moreover, this can expand the cap body from the outside and make the inside of the cap body cleaner.

[0025] Example 2: Please refer to Figure 2 As shown, this utility model provides an optimized technical solution for embodiment 1: a knob 6 is fixed at one end of the drive rod 5 located outside the drive box 41. The knob 6 facilitates the rotation of the drive rod 5. In addition, the side of the knob 6 away from the drive box 41 is a flat end face. After the hat body is expanded, the drive rod 5 can be swung to a vertical state. At this time, the flat end face of the knob 6 can be used to directly and stably support the entire hat support frame and hat body. In this way, the entire hat body is suspended in the air, which helps to maintain the flatness of the hat body when stored, and makes the hat body more beautiful when displayed.

[0026] Example 3: Please refer to Figure 4As shown, this utility model provides an optimized technical solution for embodiment 2: a limiting guide rod 7 is also provided between the two support bodies 1. The limiting guide rod 7 passes through both support bodies 1 and is fixedly connected to the drive box 41. With this design, when the bidirectional screw 2 is rotated to expand the support body 1, there is no need to restrict the support body 1. The support body 1 will no longer follow the rotation of the bidirectional screw 2 and affect its continuous expansion, making the support of the cap body more convenient.

[0027] Example 4: Please refer to Figure 5 As shown, this utility model provides an optimized technical solution for embodiment 3: a polygonal extension groove 51 is provided at the end of the drive rod 5, a polygonal extension rod 52 slides in the polygonal extension groove 51, the knob 6 is fixed to the end of the polygonal extension rod 52, and a locking pin 53 is threaded through the drive rod 5. With this design, when the polygonal extension rod 52 moves in the polygonal extension groove 51 of the drive rod 5, the support height of the hat body can be directly changed. Especially when encountering hats with different depths, shapes and angles of the visor, it avoids the hat body touching the ground while the knob 6 has not yet touched the ground, so that the hat support frame can better adapt to different types of hat support and display use.

[0028] Example 5: Please refer to Figure 6 As shown, this utility model provides another optimized technical solution of embodiment 3: the drive rod 5 includes a fixed seat 54 and a disassembly rod 55 mounted on the drive box 41, the bevel gear B43 is mounted on the fixed seat 54, the end of the fixed seat 54 is provided with a polygonal buckle groove 56, and the end of the disassembly rod 55 is a polygonal structure that matches the polygonal buckle groove 56. With this design, especially when storing hats, by disassembling the disassembly rod 55 and the knob 6, multiple expanded hats can be stacked and stored as much as possible, thereby reducing the space occupied.

[0029] In addition, magnets 57 are embedded in the inner wall of the polygonal groove 56 and the end of the disassembly rod 55, and the magnetic poles of the opposite faces of the magnets 57 are opposite. This makes it easier to connect the disassembly rod 55 with the fixed seat 54 when the disassembly rod 55 and the knob 6 are needed to set the state of the two supports 1, and makes the connection state more stable. Especially when it is released during continuous rotation, it effectively prevents it from falling off.
