Description

Technical Field

[0001] This utility model relates to a double-door heart-shaped box with a handle, belonging to the field of double-door heart-shaped boxes. Background Technology

[0002] In daily life, the double-door heart-shaped hand-held box is undoubtedly loved by consumers for its unique romantic design and high practicality. This type of box is often carefully selected to hold precious gifts, delicate trinkets, or everyday necessities, bringing surprise and warmth to the recipient. However, despite the many advantages of heart-shaped boxes in terms of design and function, the design of the carrying strap is often imperfect. Especially when the strap is damaged due to prolonged use or accidental impact, replacing it often becomes extremely tedious and difficult, causing considerable inconvenience to the user.

[0003] The carrying strap of a heart-shaped box is a crucial component connecting the box to the user's hand, making its stability and durability paramount. Common connection methods, such as screw fixing or welding, while ensuring a tight fit to the box to some extent, reveal significant drawbacks when the strap needs replacing. These methods require specialized tools for disassembly, making the process complex and time-consuming. Careless handling can also cause irreparable damage to the box, affecting its appearance and lifespan. Furthermore, although some heart-shaped boxes on the market employ detachable carrying straps in an attempt to solve the replacement problem, these designs often fail to achieve the desired effect due to overly complex connection structures and numerous required components. Users not only need certain operating skills and patience but also need to prepare the necessary tools and parts in advance, undoubtedly increasing the difficulty and cost of replacing the strap and deterring many potential users.

[0022] 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.

[0023] Please see Figures 1 to 3 The present invention provides a technical solution: a hand-held double-door heart-shaped box, including a heart-shaped box body 1 and a carrying rope 2. Both ends of the carrying rope 2 are fixedly connected to a fixed shaft 3. The top of the heart-shaped box body 1 is provided with a connecting component for convenient replacement of the carrying rope 2.

[0024] like Figures 1 to 2As shown, the connecting assembly includes two housings 4 fixedly connected to the top of the heart-shaped box 1, a connecting shaft 5 rotatably connected to the bottom wall of the inner wall of the housing 4, a connecting cylinder 6 fixedly connected to the top of the connecting shaft 5, a transmission gear 7 fixedly connected to the outside of the connecting shaft 5, driven gears 8 respectively meshing with the left and right sides of the transmission gear 7, a threaded shaft 9 fixedly connected to the inner side of the center of the driven gear 8, a threaded block 10 threadedly connected to the outside of the threaded shaft 9, and a positioning shaft 11 fixedly connected to the opposite side wall of the left and right threaded blocks 10 respectively.

[0025] It should be noted that the upper surface of the housing 4 is provided with an extension port that is compatible with the connecting cylinder 6, and the top of the connecting cylinder 6 extends to the outside of the housing 4 through the corresponding extension port.

[0026] The inner side of the connecting cylinder 6 is provided with a connecting slot that is compatible with the fixed shaft 3, and the upper surface of the connecting cylinder 6 is provided with an insertion port that is compatible with the fixed shaft 3 and communicates with the corresponding connecting slot.

[0027] The outer side wall of the fixed shaft 3 is provided with a positioning slot that is compatible with the positioning shaft 11, and the outer side wall of the connecting cylinder 6 is provided with a through hole that is compatible with the positioning shaft 11 and connected to the corresponding positioning slot.

[0028] The left end of the left threaded shaft 9 is rotatably connected to the inner left side wall of the housing 4, and the right end of the right threaded shaft 9 is rotatably connected to the inner right side wall of the housing 4.

[0029] A limiting groove is provided on the inner side of the threaded block 10, and the limiting groove is located below the threaded groove of the threaded block 10. A limiting rod 12 is slidably connected to the inner side of the limiting groove. The left end of the left limiting rod 12 is fixedly connected to the inner left side wall of the housing 4, and its right end is bent downward and fixedly connected to the inner bottom wall of the housing 4. The right end of the right limiting rod 12 is fixedly connected to the inner right side wall of the housing 4, and its left end is bent downward and fixedly connected to the inner bottom wall of the housing 4. The limiting groove provided on the inner side of the threaded block 10 and the limiting rod 12 slidably connected to the limiting groove together restrict the rotational freedom of the threaded block 10, ensuring the stability and straightness of the threaded block 10 during movement, and further improving the stability and reliability of the connection.

[0030] The working principle of the above embodiments is as follows:

[0031] When the lifting rope 2 is damaged and needs to be replaced, first rotate the fixed shaft 3 to make it rotate the connecting cylinder 6. The connecting cylinder 6 then drives the connecting shaft 5 to rotate. The connecting shaft 5 drives the driven gear 8 to rotate through the transmission gear 7. The driven gear 8 then drives the threaded shaft 9 to rotate. Since the threaded block 10 is threadedly connected to the threaded shaft 9, the threaded block 10 will move along the axial direction of the threaded shaft 9. During the movement, the threaded block 10 drives the positioning shaft 11 to move, thereby causing the positioning shaft 11 to be pulled out from the positioning hole of the fixed shaft 3. This allows the fixed shaft 3 to be removed from the housing 4, and the damaged lifting rope 2 can then be removed from the top of the heart-shaped box 1.

[0032] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
