[0001] The present application relates to the technical field of decoration articles, in particular a Christmas decoration box, and relates to a portable decoration box and foldable supporting column. BACKGROUND

[0002] As shown in FIG. 1, the decoration box is widely used in festivals, birthdays and anniversaries as a decoration to set the atmosphere, such as a decoration box placed under a Christmas tree during the Christmas season. The common decoration box is mainly composed of a decoration layer on the outside and a frame in the inside. A lamp strip is arranged in the inside to make light pass through the inside decoration layer and set the atmosphere with various patterns on the decoration layer to achieve the desired effect. The frame supports the decoration layer to ensure the flatness and integrity of the decoration layer and the stability of the frame. The whole type is not convenient for long-distance transportation and long-term storage due to its large volume and large space occupation.

[0003] In order to reduce the space waste in storage and transportation, the prior art provides a foldable decoration gift box. The side frame and the top frame are connected by a movable connecting piece and a connecting fixing piece. The gift box is folded during transportation to reduce the volume of the gift box and improve the space utilization rate during transportation. The frame is prevented from being bent during transportation. The box body is provided with colored lamps to improve the appearance of the gift box. However, the frame is prone to installation error due to the assembly forming, and additional wiring is required, which is difficult to install. TECHNICAL PROBLEM

[0004] The present application aims to solve the above problems of the prior art. The technical problem to be solved by the present application is how to save space while avoiding installation. TECHNICAL SOLUTION

[0005] The purpose of the present application can be achieved by the following technical scheme: a portable decoration box, comprising two frame bodies arranged vertically, a plurality of foldable supporting columns arranged between the two frame bodies, the frame bodies and the supporting columns forming a three-dimensional supporting framework of the gift box, and a lock structure arranged between the two frame bodies, characterized in that the supporting column comprises two connecting rods and a spiral spring fixed between the two connecting rods, the two connecting rods are located on the axis of the spiral spring to form a straight line, the middle pitch of the spiral spring is smaller than the pitch of the two ends, when the two frame bodies are close to form a folded state and the lock structure is locked, the supporting column is bent at the spiral spring, and when the lock structure is unlocked, the supporting column can be reset to a straight state under the action of the spiral spring.

[0006] The principle of the present application is that after folding the support column, the two frame bodies are locked and connected through the lock catch structure, thereby reducing the waste of transportation and storage space, locking the two frame bodies through the lock catch structure, improving the stability of the gift box in the folded state, and replacing the original rigid connection of the splicing piece with flexible connection of the spiral spring, and adjusting the pitch of the spiral spring based on the existing spiral spring, so that the middle pitch of the spiral spring is smaller than the pitch of the two ends of the spiral spring, thereby improving the lateral stiffness of the spiral spring, without the need to additionally increase the plug-in part between the two connecting rods, so as to ensure the support strength of the three-dimensional support framework in the unfolded state, and fix the two ends of the spiral spring on the two connecting rods, thereby increasing the contact area of the spiral spring and the two connecting rods, and prolonging the force arm, reducing the impact of the improvement of the lateral stiffness of the spiral spring on the folding of the framework, ensuring its normal use, and through the elastic force generated by the spiral spring during the resetting process, the decorative surface covering the three-dimensional support framework is relatively smooth and does not wrinkle, thereby improving the aesthetic degree of the gift box during use.

[0007] Accordingly, the present application connects the two connecting rods through the spiral spring, so that it can be folded, and the user only needs to unlock the lock catch structure between the two frame bodies, and push the frame body upward to form a decorative box through the force generated by the elastic deformation of the spiral spring during folding, thereby avoiding installation.

[0008] In the above-mentioned elastic pressure portable decorative box, the middle part of the spiral spring is located between the end faces of the two connecting rods, the two connecting rod ends have embedding grooves, and the parts with larger pitch of the spiral spring are connected with the embedding grooves through clamping. By clamping the two ends with larger pitch of the spiral spring with the embedding grooves, the contact area with the connecting rod is increased, and the end part of the spiral spring is not lifted, thereby improving the reliability of the connection.

[0009] In the above-mentioned elastic pressure portable decorative box, the upper and lower ends of the support column are respectively hingedly connected with the two frame bodies, the upper and lower ends of the support column are respectively provided with an outer blocking surface and an inner circular surface, and the blocking surface can abut against the frame body. By abutting the blocking surface against the frame body, the failure caused by the outward folding of the support rod to make the spiral spring disengage from the connecting rod is avoided.

[0010] In the above-mentioned elastic pressure portable decorative box, the frame body is provided with a hinge part symmetrically arranged on the left and right sides, a cross beam is arranged between the two support columns, and the support column is hingedly connected with the hinge part through the cross beam.

[0011] In the elastic portable decoration box, the hinge part is provided with a protrusion, and the cross beam is provided with a resisting part, and when the supporting column is reset to a straight state under the action of the spiral spring, the resisting part abuts against the protrusion. Through the cooperation of the protrusion and the cross beam, the supporting column is further prevented from being folded outward, and the stability of the framework during use is improved.

[0012] In the elastic portable decoration box, the lock structure comprises a locking piece and a clamping column, the locking piece and the clamping column are respectively arranged on the front and rear sides of the frame body, and the locking piece and the clamping column on the two frame bodies are respectively arranged opposite to each other. The lock structure is prevented from interfering with the hinge part.

[0013] In the elastic portable decoration box, the supporting column, the cross beam and the frame body are all provided with a fixing part for mounting a lamp strip, and the supporting framework covers the lamp strip, and when the lock structure is unlocked, the supporting spring pushes the upper frame body to move upward and tightly abuts against the top decorative cloth. By arranging the fixing part on the framework, the lamp strip is conveniently mounted, and the gift box is more beautiful in the use state.

[0014] A foldable supporting column, characterized by comprising two connecting rods and a spiral spring fixed between the two connecting rods, the two connecting rods are located on the axis of the spiral spring to form a straight line, and the pitch of the middle part of the spiral spring is smaller than the pitch of the two ends.

[0015] The application flexibly connects the two connecting rods by the spiral spring, meets the folding of the supporting column, adjusts the pitch of the middle part and the two ends of the spiral spring, improves the supporting strength of the spiral spring, and improves the use experience.

[0016] In the elastic portable decoration box, the middle part of the spiral spring is located between the end faces of the two connecting rods, the end parts of the two connecting rods have embedding grooves, and the parts with larger pitch of the spiral spring are connected with the embedding grooves.

[0017] In the elastic portable decoration box, the upper and lower ends of the supporting column are respectively provided with a blocking surface and a circular arc surface, and the supporting column is folded towards the circular arc surface. The interference between the frame body and the supporting column during folding is avoided. Advantages

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.

[0029] As shown in FIG. 2 and FIG. 3, the present application comprises two frame bodies 1 arranged in up and down, and the two frame bodies 1 are connected by support columns 2, the support column 2 comprises two connecting rods 201 arranged in up and down and a spiral spring 202 between the two connecting rods 201, the end of the two connecting rods 201 is provided with an embedded groove 2011 for installing the spiral spring 202, the two support columns 2 are connected by a cross beam 3 and form two oppositely arranged U-shaped frames, the frame body 1 is provided with a hinged part 102, the hinged part 102 is provided with a protrusion 1021, the cross beam 3 is provided with a resisting part 301, the resisting part 301 abuts against the protrusion 1021, wherein the pitch of the two ends of the spiral spring 202 is larger than the pitch of the middle part of the spiral spring 202, the two ends of the spiral spring 202 with wider pitch are clamped and connected with the embedded groove 2011 on the connecting rod 201 for fixation, and the cross beam 3 is hingedly connected with the hinged part 102. In terms of pitch, it actually refers to the distance between the adjacent two coils of the spring except the top and bottom coils. The hinged part 102 is provided with an opening on both sides, the cross beam is provided with a pin shaft oppositely arranged with the opening, the pin shaft is clamped into the opening to complete the hinged connection, wherein the end of the pin shaft towards the hinged part is provided with an inclined surface, and the specific embodiment can also provide the pin shaft on the hinged part to cooperate with the opening on the cross beam. In terms of the specific hinged structure, it is the common knowledge in the field, and will not be described here.

[0030] It is worth mentioning that in addition to the protrusion 1021 on the hinged part 102 abutting against the resisting part 301 on the cross beam 3, the upper and lower ends of the support column 2 are also provided with a blocking part and a circular arc surface 2013, as shown in FIG. 2, the blocking part is located on the outer side of the support column 2, and the circular arc surface 2013 faces the lock structure 101. The lock structure 101 comprises a clamping column 1012 and a locking piece 1011, the clamping column 1012 and the locking piece 1011 are respectively located on the front and rear sides of the frame body 1 and oppositely arranged with the clamping column 1012 and the locking piece 1011 on the other frame body 1, and the hinged part 102 is located on the left and right sides of the frame body 1. The locking piece 1011 is a rebounder, which is widely used in various products and will not be described here.

[0031] As shown in FIG. 4 and FIG. 5, 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 with the frame body 1, that is, the support column 2 is bent towards the lock structure 101 until the locking piece 1011 is clamped and connected with the clamping column 1012, wherein the pitch of the middle part of the spiral spring 202 is larger than the pitch of the two ends.

[0032] As shown in FIG. 6, the cross beam 3, the support column 2 and the frame body 1 are all provided with a fixing part 4, the fixing part 4 is L-shaped and leaves a certain space between the frame body 1, the support column 2 and the cross beam 3, for clamping the sheet-shaped strip-shaped lamp strip 5 in the fixing part 4.

[0033] In summary, on the basis of the original three-dimensional support frame, two cross beams 3 are additionally added between the two support columns 2, and the support column 2 and the cross beam 3 cooperate to form two oppositely arranged U-shaped frames, and the U-shaped frame and the frame body 1 are hingedly connected through the cross beam 3 and the hinge part 102, so that the U-shaped frame can swing around the hinge part 102 towards 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 skeleton can be reduced by folding. In order to simplify the structure and reduce the installation difficulty in the production process, the existing rigid connection is replaced by a flexible connection using a spiral spring 202. In order to improve the support of the three-dimensional support skeleton for the decorative box, the pitch of the spiral spring 202 is adjusted. By making the pitch of the two ends of the spiral spring 202 greater than the pitch of the middle part, the lateral stiffness of the middle part of the spiral spring 202 is enhanced, the support strength of the three-dimensional support skeleton is improved, and by increasing the pitch of the two ends, a certain buffer is provided after pressing. By providing a slot 2011 on the connecting rod 201, the connection strength is further increased.

[0034] In addition, by connecting the two ends of the spiral spring 202 with the two connecting rods 201 of the support column 2 respectively, the force arm of the support column 2 in the bent state is further increased, and the consistency of the two support columns 2 during folding and the contact area of the folding part are ensured by the cross beam 3, which reduces the folding difficulty of the support column 2, so that the operator can overcome the influence of the smaller middle pitch on folding during the folding process. Because the spiral spring 202 is laterally bent during folding, elastic deformation occurs, so when the locking part 1011 and the clamping column 1012 of the two frame bodies 1 are unlocked, the support column 2 moves outward when the axis of the connecting rod 201 and the spiral spring 202 is in the same straight line, and pushes the frame body 1 upward to stretch the decorative surface, thereby forming a decorative box. While reducing the accommodation space, only by providing 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, which eliminates the need for installation of the decorative box. Because of the existence of the spiral spring 202, the three-dimensional support skeleton can be applied to decorative boxes of different heights, improving the range of use, and the internal decorations such as the lamp strip 5 can be directly fixed to the fixed part 4, further improving the use experience.
