Description

Technical Field

[0001] The utility model relates to the technical field of decorative articles, in particular to a Christmas holiday decoration box, and relates to a spring-loaded portable decoration box and a foldable support column. Background Art

[0002] As Figure 1 shown, as a decorative piece for setting off the atmosphere, the decoration box is widely used in occasions such as festivals, birthdays, and anniversaries. For example, the decoration gift box placed under the Christmas tree during the Christmas holiday. The common decoration box mainly consists of a decorative layer covered on the outside and a frame located inside. By setting light strips inside, light energy can penetrate from the inner decorative layer, and various patterns on the decorative layer are used to set off the atmosphere to achieve the desired effect. The frame supports the decorative layer to ensure the flatness and integrity of the decorative layer and the stability of the frame. Among them, the integral type occupies a large space due to its large volume, so it is not convenient for long-distance transportation and long-term storage.

[0003] In order to reduce the waste of space during storage and transportation, the prior art provides a foldable decorative gift box. The side frame and the top frame are connected by movable connecting pieces and connecting and fixing pieces. The gift box is folded during transportation to reduce the volume of the gift box and improve the space utilization rate during transportation. And it avoids the frame from being bent during transportation, and color lights are arranged on the box body to improve the beauty of the gift box. However, since it is assembled and formed, the frame is easy to be installed incorrectly and requires additional wiring, making it difficult to install. Summary of the Utility Model

[0004] The purpose of the present utility model is to address the above problems existing in the prior art and propose a spring-loaded portable decoration box. The technical problem to be solved by the present utility model is: how to save space while avoiding installation.

[0005] The purpose of the present utility model can be achieved by the following technical solutions: A spring-loaded portable decoration box includes two frames arranged up and down. A plurality of foldable support columns are arranged between the two frames. The frames and the support columns constitute the three-dimensional support framework of the decoration box. A locking structure is provided between the two frames. It is characterized in that the support column includes two connecting rods and a spiral spring fixedly connected between the two connecting rods. Both connecting rods are located on the axis of the spiral spring so that the three form a straight line. The pitch of the middle part of the spiral spring is smaller than the pitch of the two ends. When the two frames approach to form a folded state and the above-mentioned locking structure is locked, the support column bends at the spiral spring. When the locking structure is unlocked, the support column can be reset to a straight state under the action of the spiral spring.

[0006] The basic principle of this application is that after folding the support columns, the two frames are locked and connected through a locking structure. Thus, while reducing the waste of transportation and storage space, the two frames are locked through the locking structure, enhancing the stability of the gift box in the folded state. Moreover, for the folding structure of the three-dimensional support skeleton, the original rigid connections such as splicing parts are replaced with flexible connections of spiral springs. Based on the existing spiral springs, the pitch of the spiral springs is adjusted so that the pitch in the middle of the spiral spring is smaller than the pitch at both ends of the spiral spring, thereby enhancing the lateral stiffness of the spiral spring. Without adding additional plug-in parts between the two connecting rods, the support strength of the three-dimensional support skeleton in the unfolded state can be ensured. And by fixing both ends of the spiral spring to the two connecting rods respectively, while increasing the contact area between the spiral spring and the two connecting rods, the force arm of the work is extended, reducing the impact of the increase in the lateral stiffness of the spiral spring on the folding of the skeleton, ensuring its normal use. And through the elastic force generated by the spiral spring during the reset process, the decorative surface covering the three-dimensional support skeleton is relatively smooth without wrinkles, enhancing the aesthetic degree of the gift box during use.

[0007] Accordingly, in this application, the two connecting rods are connected by a spiral spring, enabling them to be folded. At the same time, the user only needs to unlock the locking structure between the two frames, and the force generated by the elastic deformation during the folding of the spiral spring pushes the frame upward to form a decorative box, thus eliminating the need for installation.

[0008] In the above-mentioned spring-loaded portable decorative box, the middle part of the spiral spring is located between the end faces of the two connecting rods. Both ends of the two connecting rods are provided with grooves, and the parts with a larger pitch of the spiral spring are snap-connected to the grooves. By snap-connecting the two ends with a larger pitch in the middle of the spiral spring to the grooves, the contact area with the connecting rod is increased, and the end of the spiral spring will not... (the text seems incomplete here), enhancing the reliability of the connection.

[0009] In the above-mentioned spring-loaded portable decorative box, the upper and lower ends of the support column are respectively hinged to the two frames. The upper and lower ends of the support column are both provided with a blocking surface on the outside and a circular arc surface on the inside, and the blocking surface can abut against the frame. By the blocking surface abutting against the frame, it is possible to prevent the support rod from folding outwards, resulting in the spiral spring detaching from the connecting rod and causing failure.

[0010] In the above-mentioned spring-loaded portable decorative box, hinge parts are symmetrically arranged on the left and right of the frame. A cross beam is provided between the two support columns, and the support column is hinged to the hinge part through the cross beam.

[0011] In the above-mentioned resilient and portable decorative box, a convex block is provided on the hinge portion, and a resisting portion is formed on the cross beam. When the support column returns to a straight state under the action of the spiral spring, the resisting portion abuts against the convex block. Through the cooperation of the convex block and the cross beam, the outward folding of the support column is further avoided, thereby enhancing the stability of the framework during use.

[0012] In the above-mentioned resilient and portable decorative box, the buckle structure includes a locking member and a clamping column. The locking member and the clamping column are respectively located on the front and rear sides of the frame body, and the locking members and the clamping columns on the two frame bodies are arranged opposite to each other respectively, so as to avoid interference between the buckle structure and the hinge portion.

[0013] In the above-mentioned resilient and portable decorative box, fixing portions are provided on the support column, the cross beam and the frame body. The fixing portions are used for installing the light strip. When the buckle structure is unlocked, the support spring pushes the upper frame body upward to closely fit with the top decorative cloth. By providing fixing portions on the framework, it is convenient to install the light strip, making the gift box more beautiful in the use state.

[0014] A foldable support column, characterized in that it includes two connecting rods and a spiral spring fixedly connected between the two connecting rods. The two connecting rods are both located on the axis of the spiral spring so that the three form a straight line, and the pitch of the middle part of the spiral spring is smaller than the pitches at both ends.

[0015] In this application, the two connecting rods are flexibly connected by a spiral spring. While meeting the requirement that the support column can be folded, by adjusting the pitch changes of the middle part and both ends of the spiral spring, the support strength of the spiral spring is improved, thereby enhancing the use experience.

[0016] In the above-mentioned foldable support column, the middle part of the spiral spring is located between the end faces of the two connecting rods, and the end parts of the two connecting rods have embedding grooves, and the parts with larger pitch of the spiral spring are clamped and connected with the embedding grooves.

[0017] In the above-mentioned foldable support column, a blocking surface and an arc surface are respectively provided at the upper and lower ends of the support column, and the support column folds towards the arc surface, so as to avoid interference between the frame body and the support column during the folding process.

[0018] Compared with the prior art, the present utility model has the following advantages:

[0019] In this application, the side frame is divided into upper and lower parts, the two connecting rods are connected by spiral springs at the ends, and the change of the pitch of the spiral spring is utilized. While ensuring the support for the framework, it can be folded, thereby reducing the volume during storage and transportation. And only by pressing the frame body to unlock, the elastic deformation formed by lateral bending can be used to complete the switching between the folded state and the unfolded state, eliminating the need for installation.

Specific embodiments

[0027] The following are specific embodiments of the present utility model and in combination with the accompanying drawings, the technical solutions of the present utility model are further described, but the present utility model is not limited to these embodiments.

[0028] As Figure 1 shown, the decorative box of the present application is mainly used for holiday decorations such as Christmas, and it includes a frame and a decorative cloth wrapped outside the frame. The frame supports the decorative cloth, and a light strip is arranged in the frame. The light emitted by the light strip penetrates from inside the decorative cloth and cooperates with the components attached to the decorative cloth to play a decorative role.

[0029] As Figure 2 and Figure 3As shown in the figure, the present application includes two frame bodies 1 arranged vertically. The two frame bodies 1 are connected by support columns 2. The support column 2 includes two connecting rods 201 arranged vertically and a spiral spring 202 located between the two connecting rods 201. Embedding grooves 2011 are provided at the ends of the two connecting rods 201 for installing the spiral spring 202. The two support columns 2 are connected by a cross beam 3 and form two U-shaped frames arranged opposite to each other. A hinge part 102 is provided on the frame body 1, and a convex block 1021 is provided on the hinge part 102. A resisting part 301 is provided on the cross beam 3, and the resisting part 301 abuts against the convex block 1021. Among them, the pitch at both ends of the spiral spring 202 is greater than the pitch in the middle of the spiral spring 202. The two ends of the spiral spring 202 with a wider pitch are snap-connected to the embedding grooves 2011 on the two connecting rods 201 for fixation. The cross beam 3 is hingedly connected to the hinge part 102. In terms of the pitch, it actually refers to the distance between two adjacent coils of the spring except for the coils at the top and bottom. Openings are provided on both sides of the hinge part 102, and a pin shaft is provided on the cross beam opposite to the opening. By snapping the pin shaft into the above-mentioned opening, the hinged connection is completed. Among them, one end of the pin shaft facing the hinge part is provided with an inclined surface. Specifically, the pin shaft can also be provided on the hinge part and cooperate with the opening on the cross beam. In terms of the specific hinge structure, it is common knowledge in the art and will not be elaborated here.

[0030] It is worth mentioning that in addition to the convex block 1021 on the hinge part 102 abutting against the resisting part 301 on the cross beam 3, blocking parts and arc surfaces 2013 are also provided at the upper and lower ends of the support column 2, as Figure 2 shown. The blocking part is located outside the support column 2, and the arc surface 2013 faces the lock structure 101. The lock structure 101 includes a clamping column 1012 and a locking member 1011. The clamping column 1012 and the locking member 1011 are respectively located on the front and back sides of the frame body 1 and are arranged opposite to the clamping column 1012 and the locking member 1011 on the other frame body 1. The hinge part 102 is located on the left and right sides of the frame body 1. Among them, the locking member 1011 is a rebounder, and the rebounder is widely used in various products and will not be elaborated here.

[0031] As Figure 4 and Figure 5 shown, when folding the three-dimensional support framework of the present application, the support column 2 rotates inward around the position where the support column 2 is connected to the frame body 1, that is, the support column 2 bends towards the lock structure 101 until the locking member 1011 is snap-connected to the clamping column 1012. Among them, the pitch in the middle of the spiral spring 202 is greater than that at both ends.

[0032] As Figure 6 shown, fixing parts 4 are provided on the cross beam 3, the support column 2 and the frame body 1. The fixing part 4 is L-shaped, and there is a certain space between the fixing part 4 and the frame body 1, the support column 2 and the cross beam 3 for snap-connecting a sheet-shaped long strip light belt 5 into the fixing part 4.

[0033] In summary, based on the original three-dimensional support framework, two additional cross beams 3 are added between the two support columns 2. The support columns 2 and the cross beams 3 are cooperated to form two oppositely arranged U-shaped frames. The U-shaped frames and the frame body 1 are hingedly connected through the cross beams 3 and the hinge parts 102, so that the U-shaped frames can swing around the hinge parts 102 towards the locking structures 101 on the frame body 1, enabling the frame body 1 to be folded, and reducing the volume of the three-dimensional support framework through folding. Among them, to simplify the structure and reduce the installation difficulty during the production process, the existing rigid connection is replaced with a flexible connection using a spiral spring 202. On this basis, to improve the support of the three-dimensional support framework for the decorative box, the pitch of the spiral spring 202 is adjusted. By making the pitch at both ends of the spiral spring 202 greater than the pitch in the middle, the lateral stiffness in the middle of the spiral spring 202 is enhanced, the support strength of the three-dimensional support framework is improved, and by increasing the pitch at both ends, while having a certain buffer after being pressed down, the connection strength is increased by providing a groove 2011 on the connecting rod 201.

[0034] In addition, by connecting the two ends of the spiral spring 202 to the two connecting rods 201 of the support column 2 respectively, the force arm of the support column 2 in the bent state is increased, and the cross beam 3 ensures the consistency of the two support columns 2 during the folding process and the contact area at the folding part, reducing the folding difficulty of the support column 2, enabling the operator to overcome the influence of the reduced pitch in the middle on folding during the folding process. And because during the folding process, the spiral spring 202 undergoes lateral bending and thus elastic deformation, when the locking parts 1011 and the clamping columns 1012 of the two frame bodies 1 are unlocked, affected by the elastic deformation, the support column 2 recovers the deformation. When the two connecting rods 201 and the axis line of the spiral spring 202 are in the same straight line, it moves outwards and pushes the frame body 1 to move upwards, stretching the decorative surface to form a decorative box. While reducing the accommodation space, only by setting a flexible connecting piece using a spiral spring 202 between the ends of the two connecting rods 201, the switching from the folded state to the unfolded state can be completed by pressing the frame body 1, eliminating the installation of the decorative box. And due to the existence of the spiral spring 202, the three-dimensional support framework can be applicable to decorative boxes of different heights, improving the scope of use. The internal decorations such as the light strip 5 can be directly fixed on the fixing part 4, further enhancing the use experience.
