Description

Technical Field

[0001] This invention relates to the field of decorative products technology, particularly Christmas and holiday decorative boxes, and specifically to a spring-loaded portable decorative box. Background Technology

[0002] like Figure 1 As shown, decorative boxes, as decorative items to enhance the atmosphere, are widely used in occasions such as holidays, birthdays, and anniversaries. For example, decorative gift boxes placed under Christmas trees during the Christmas season. Common decorative boxes mainly consist of an outer decorative layer and an inner frame. By setting up light strips inside, light can shine through the inner decorative layer, enhancing the atmosphere with various patterns on the decorative layer to achieve the desired effect. The frame supports the decorative layer, ensuring its flatness and integrity, and ensuring the stability of the frame. However, the one-piece type is relatively large and occupies a lot of space, making it inconvenient for long-distance transportation and long-term storage.

[0003] To reduce space waste during warehousing and transportation, existing technologies offer foldable decorative gift boxes. These boxes connect the side frames to the top frame using movable connectors and fasteners. The gift box is folded during transportation to reduce its volume, improve space utilization, and prevent the frame from bending during transport. Colored lights are also added to enhance the box's aesthetics. However, because these boxes are assembled from parts, the frame is prone to installation errors and requires additional wiring, making installation difficult. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a spring-loaded portable decorative box. The technical problem this invention aims to solve is: how to save space while eliminating the need for installation.

[0005] The objective of this invention can be achieved through the following technical solution: a spring-loaded portable decorative box, comprising two frames arranged vertically, with a plurality of foldable support columns disposed between the two frames, the frames and support columns forming a three-dimensional support skeleton for the gift box, and a locking structure provided between the two frames, characterized in that the support column comprises two connecting rods and a helical spring fixed between the two connecting rods, the two connecting rods being located on the axis of the helical spring so that the three form a straight line, the pitch of the middle part of the helical spring being smaller than the pitch of the two ends, when the two frames are close together to form a folded state and the above-mentioned locking structure is locked, the support column bends at the helical spring, and when the locking structure is unlocked, the support column can return to a straight state under the action of the helical spring.

[0006] The basic principle of this application is to fold the support column and then lock the two frames together using a locking structure. This reduces waste in transportation and storage space while enhancing the stability of the gift box in the folded state. Furthermore, the folding structure of the three-dimensional support frame replaces rigid connections such as splicing parts with flexible connections using helical springs. The pitch of the helical springs is adjusted so that the pitch in the middle is smaller than the pitch at both ends, thus increasing the lateral stiffness of the springs. This eliminates the need for additional connectors between the two connecting rods, ensuring the support strength of the three-dimensional support frame in the unfolded state. Fixing both ends of the helical springs to the two connecting rods increases the contact area between the springs and the rods, lengthens the lever arm, and reduces the impact of the increased lateral stiffness of the springs on the folding of the frame, ensuring normal use. The elastic force generated by the helical springs during the reset process makes the decorative surface covering the three-dimensional support frame smooth and wrinkle-free, improving the aesthetics of the gift box during use.

[0007] Accordingly, this application connects the two links by a helical spring, allowing them to be folded. At the same time, the user only needs to unlock the locking structure between the two frames. The force generated by the elastic deformation of the helical spring during the folding process pushes the frame upward to form a decorative box, thus eliminating the need for installation.

[0008] In the aforementioned spring-loaded portable decorative box, the middle portion of the helical spring is located between the end faces of the two connecting rods. The ends of the two connecting rods have grooves, and the portion of the helical spring with the larger pitch engages with these grooves. By engaging the two ends of the helical spring with the grooves, the contact area with the connecting rods is increased, and the ends of the helical spring are prevented from slipping, thus improving the reliability of the connection.

[0009] In the aforementioned spring-loaded portable decorative box, the upper and lower ends of the support column are hinged to the two frames respectively. Both ends of the support column have an outer blocking surface and an inner arcuate surface, with the blocking surface abutting against the frame. This abutting against the frame prevents the support column from folding outwards, which could cause the coil spring to disengage from the connecting rod and result in failure.

[0010] In the aforementioned spring-loaded portable decorative box, hinges are symmetrically arranged on the frame, and a crossbeam is provided between the two support columns. The support columns are hinged to the hinges via the crossbeam.

[0011] In the aforementioned spring-loaded portable decorative box, a protrusion is provided on the hinge portion, and a stop portion is provided on the crossbeam. When the support column returns to a straight position under the action of the helical spring, the stop portion abuts against the protrusion. The cooperation between the protrusion and the crossbeam further prevents the support column from folding outward, thus improving the stability of the frame during use.

[0012] In the aforementioned spring-loaded portable decorative box, the locking structure includes a locking element and a locking pin. The locking element and the locking pin are located on the front and rear sides of the frame, respectively, and the locking elements and locking pins on the two frames are respectively arranged opposite to each other. This prevents interference between the locking structure and the hinge.

[0013] In the aforementioned spring-loaded portable decorative box, the support column, crossbeam, and frame are all equipped with fixing parts for mounting LED strips. The support frame covers the box, and when the locking structure is unlocked, the support spring pushes the upper frame upward to fit tightly against the top decorative fabric. By providing fixing parts on the frame, it is easy to install LED strips, making the gift box more aesthetically pleasing in use.

[0014] A foldable support column is characterized by comprising two connecting rods and a helical spring fixed between the two connecting rods, wherein the two connecting rods are both located on the axis of the helical spring so that the three form a straight line, and the pitch of the helical spring in the middle is smaller than the pitch of the two ends.

[0015] This application achieves a flexible connection between two connecting rods via a helical spring. While ensuring the support column can be folded, the support strength of the helical spring is improved by adjusting the pitch of the middle and both ends of the helical spring, thereby enhancing the user experience.

[0016] In the aforementioned spring-loaded portable decorative box, the middle part of the helical spring is located between the end faces of the two connecting rods, and the ends of the two connecting rods have grooves. The larger pitch portion of the helical spring is engaged with the groove.

[0017] In the aforementioned spring-loaded portable decorative box, the upper and lower ends of the support column are respectively provided with a blocking surface and an arc surface, and the support column is folded towards the arc surface. This avoids interference between the frame and the support column during the folding process.

[0018] Compared with the prior art, the present invention has the following advantages: This application divides the side frame into upper and lower sections and connects the two connecting rods through helical springs at the ends. By utilizing the change in the pitch of the helical springs, the frame can be folded while maintaining its support, thereby reducing the volume during storage and transportation. Moreover, the folded state can be switched to the unfolded state simply by pressing the frame to unlock it, and the elastic deformation formed after lateral bending can complete the switch, eliminating the need for installation.

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figure 1 As shown, the decorative box of this application is mainly used for decorations such as Christmas. It includes a frame and a decorative cloth covering the outside of the frame. The frame supports the decorative cloth, and a light strip is set inside the frame. The light emitted by the light strip shines through the decorative cloth and works in conjunction with the components attached to the decorative cloth to achieve a decorative effect.

[0022] like Figure 2 as well as Figure 3As shown, this application includes two frames 1 arranged vertically, connected by a support column 2. The support column 2 includes two connecting rods 201 arranged vertically and a helical spring 202 located between the two connecting rods 201. The ends of the two connecting rods 201 are provided with grooves 2011 for installing the helical spring 202. The two support columns 2 are connected by a crossbeam 3, forming two U-shaped frames arranged opposite each other. The frame 1 is provided with a hinge part 102, and the hinge part 102 is provided with a protrusion 1021. The crossbeam 3 is provided with a stop part 301, which abuts against the protrusion 1021. The pitch at both ends of the helical spring 202 is greater than the pitch at the middle of the helical spring 202. The two ends of the helical spring 202 with the wider pitch are engaged with the grooves 2011 on the two connecting rods 201 for fixation. The crossbeam 3 is hinged to the hinge part 102. In terms of pitch, it essentially refers to the distance between two adjacent coils of the spring, excluding the top and bottom coils. The hinge portion 102 has openings on both sides, and a pin is provided on the crossbeam opposite to the opening. The hinge connection is completed by engaging the pin into the opening. The end of the pin facing the hinge portion has an inclined surface. Alternatively, a pin can be provided on the hinge portion to mate with the opening on the crossbeam. The specific hinge structure is common knowledge in the art and will not be elaborated upon here.

[0023] It is worth mentioning that, in addition to the protrusion 1021 on the hinge 102 abutting against the stop 301 on the crossbeam 3, the upper and lower ends of the support column 2 are also provided with blocking parts and arc surfaces 2013, such as Figure 2 As shown, the blocking part is located outside the support column 2, and the arc surface 2013 faces the locking structure 101. The locking structure 101 includes a locking post 1012 and a locking member 1011. The locking post 1012 and the locking member 1011 are located on the front and rear sides of the frame 1, respectively, and are opposite to the locking post 1012 and the locking member 1011 on another frame 1. The hinge part 102 is located on the left and right sides of the frame 1. The locking member 1011 is a rebound device, which is widely used in various products and will not be described in detail here.

[0024] like Figure 4 and Figure 5 As shown, when the three-dimensional support frame of this application is folded, the support column 2 rotates inward around the position where the support column 2 is connected to the frame 1, that is, the support column 2 bends toward the locking structure 101 until the locking member 1011 is engaged with the locking post 1012. The pitch of the middle part of the helical spring 202 is greater than the pitch of the two ends.

[0025] like Figure 6 As shown, the crossbeam 3, the support column 2, and the frame 1 are all provided with fixing parts 4. The fixing parts 4 are L-shaped and have a certain space between them and the frame 1, the support column 2, and the crossbeam 3, which is used to snap the sheet-like long strip light 5 into the fixing parts 4.

[0026] In summary, this application adds two additional crossbeams 3 between the two support columns 2 on the basis of the original three-dimensional support frame, and forms two U-shaped frames with the support columns 2 and crossbeams 3. The U-shaped frames and the frame body 1 are hinged to the hinge part 102 through the crossbeams 3, so that the U-shaped frames can swing around the hinge part 102 toward the locking structure 101 on the frame body 1, so that the frame body 1 can be folded, and the volume of the three-dimensional support frame is reduced by folding. In order to simplify the structure and reduce the installation difficulty in the production process, the existing rigid connection is replaced with a flexible connection using a helical spring 202. On this basis, in order to improve the support of the three-dimensional support frame for the decorative box, the pitch of the helical spring 202 is adjusted. By making the pitch at both ends of the helical spring 202 greater than the pitch in the middle, the lateral stiffness of the middle part of the helical spring 202 is enhanced, thereby improving the support strength of the three-dimensional support frame. By increasing the pitch at both ends, a certain buffer is provided after pressing down. In addition, the connection strength is increased by setting the groove 2011 on the connecting rod 201.

[0027] Furthermore, by connecting the two ends of the helical spring 202 to the two connecting rods 201 of the support column 2, the lever arm of the support column 2 in the bent state is increased. The crossbeam 3 ensures consistency of the two support columns 2 during the folding process and the contact area of ​​the folded parts, reducing the difficulty of folding the support column 2. This allows the operator to overcome the impact of the reduced pitch in the middle during folding. Also, because the helical spring 202 undergoes lateral bending during folding, resulting in elastic deformation, when the locking parts 1011 and the locking post 1012 of the two frames 1 are unlocked, the support column 2 recovers its deformation due to the elastic deformation, causing the two connecting rods 201 and... When the axis of the helical spring 202 is in a straight line, it moves outward and pushes the frame 1 upward, stretching the decorative surface to form a decorative box. While reducing the storage space, the flexible connector using the helical spring 202 between the ends of the two connecting rods 201 can be used to switch from the folded state to the unfolded state by pressing the frame 1, eliminating the need to install the decorative box. Furthermore, due to the presence of the helical spring 202, the three-dimensional support frame can be used for decorative boxes of different heights, increasing its range of applications. Internal decorations such as the light strip 5 can be directly fixed to the fixing part 4, further enhancing the user experience.
