Description

Technical Field

[0001] This utility model relates to the field of shelving technology, specifically a combined support rod frame. Background Technology

[0002] In daily life, various storage baskets, racks, hooks, and rods are often needed to store and hang various household items such as clothing and shoes. However, installing such racks and rods in a room often requires fixing them to the walls using methods that damage the wall structure, such as screws or glue. These methods not only leave permanent damage to the wall but also lack flexibility, as they do not allow for easy relocation or repositioning later. Furthermore, poor wall quality and stress concentration at connection points can cause the connections to fail, leading to the racks falling off and raising reliability issues. Utility Model Content

[0003] In view of the problems mentioned in the background art regarding the lack of flexibility and poor installation stability of traditional storage devices, a combined support frame with simple installation, reliable connection and fixation and high installation and use flexibility is proposed to facilitate the setting and movement of storage devices.

[0004] This utility model discloses a combined support frame, comprising combined support rods, support legs, and movable buckles. The ends of the combined support rods have internal cavities with communicating end faces and are fixedly equipped with detachable connecting parts. The connecting parts on different combined support rods are detachably connected to each other. The support frame is composed of any number of combined support rods connected together. Support legs are located at the outermost ends of the combined support rods at both ends of the support frame. One end of the support leg passes through the connecting part at the outer end of the combined support rod and extends into the internal cavity of the combined support rod. Any position on the extended part of the support leg can form a releasable locking connection with the penetrating connecting part, allowing the support leg to have variable adjustment capability for its extension and retraction length. The end of the movable buckle, used to expand the storage points, has a non-enclosed friction locking part. The movable buckle has the ability to be detachably connected to any circumferential position of the combined support rod through the friction locking part.

[0005] As a further improvement of this utility model, it also includes a male connector bracket, a female connector bracket, and a connecting post; either the male connector bracket or the female connector bracket can be detachably connected to both ends of the combined support rod. The male connector bracket has a protruding connecting part extending from one end, and the female connector bracket has a through connecting hole. The protruding connecting part can be detachably connected to the through connecting hole. Either end of the connecting post can be detachably connected to the through connecting hole for any length. The female connector bracket can be selectively detachably connected to either the male connector bracket or the connecting post.

[0006] As a further improvement of this utility model, the protruding connecting part and the through connecting hole are provided with matching threads. When different combined support rods are provided with pairs of male combined brackets and female combined brackets at adjacent ends, the protruding connecting part and the through connecting hole are threadedly connected so that the ends of different combined support rods can be indirectly and detachably connected.

[0007] As a further improvement of this utility model, the through connecting hole and the connecting column are provided with matching threads. When different combined struts are provided with female combined brackets at adjacent ends, the two ends of the connecting column are respectively threaded to the female combined brackets on different combined struts, so that the ends of different combined struts can be indirectly and detachably connected.

[0008] As a further improvement of this utility model, the support foot includes a support plate for abutting support, and the end side of the support plate is connected to an independent connecting column; the outer ends of the combined support rods at the outermost two ends of the support rod frame are fixedly provided with female combined brackets, and storage cavities with corresponding through connecting holes on the female combined brackets are opened at the ends; the connecting column extends into the storage cavity through the through connecting hole of the female combined bracket, and is detachably connected to the through connecting hole at any length position, so that the support plate and the ends of the combined support rods form an indirect connection with an adjustable axial spacing.

[0009] As a further improvement of this utility model, the through connecting hole and the connecting column are threadedly connected, and an independently rotatable female connector assembly bracket is additionally threaded on the connecting column. When the independently rotatable female connector assembly bracket abuts against the fixed female connector assembly bracket, the axial distance between the ends of the support plate and the combined support rod remains fixed.

[0010] As a further improvement of this utility model, the through connecting hole and the connecting column are threaded together, and an independently rotatable locking disc is additionally threaded onto the connecting column. An elastic element is sandwiched between the locking disc and the adjacent female connector bracket. The extension and retraction state of the elastic element changes accordingly with the interval between the locking disc and the female connector bracket. When the elastic element is in a compressed state, the axial distance between the end of the support disc and the combined support rod remains fixed.

[0011] As a further improvement of this utility model, the locking disc has an anti-slip part on its periphery, and a recessed cavity is formed on the side of the locking disc adjacent to the female connector bracket, with one end of the elastic member abutting against the inside of the recessed cavity.

[0012] As a further improvement of this utility model, the support plate is composed of an abutment plate and a fastening plate; the abutment plate and the fastening plate are detachably connected by abutting their end faces, and a limiting cavity is opened on the abutting side of the abutment plate and the fastening plate; the end of the connecting column passes through the fastening plate and extends into the limiting cavity; the end of the connecting column is provided with a detachable anti-disengagement buckle, which engages with the limiting cavity to limit the end of the connecting column within the limiting cavity.

[0013] As a further improvement of this utility model, one end of the movable buckle is provided with a spiral coiled tail. The pitch and diameter of the coiled tail are slightly larger than the diameter of the combined support rod. The coiled tail spirally surrounds the outer circumference of the combined support rod. Under the action of the movable buckle's own weight, the inner side of the coiled tail has the ability to rub against and lock the surface of the combined support rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The combined support frame of this utility model uses a support leg structure with telescopic adjustment capability to abut against the installation surface. Whether it is used for horizontal fixation or vertical fixation, it generates a fixing friction force to fix the combined support frame and additionally support the placed object without damaging the installation surface. It plays a protective and aesthetic role for the installation surface such as walls and ceilings.

[0015] 2. By adjusting the support legs and increasing or decreasing the number of connected combination support rods at any time, the modular support frame can be quickly assembled and disassembled and adapted to different span installation spaces, making it convenient for users to change and adapt to different installation positions according to specific needs.

[0016] 3. Regardless of whether the combined support rod is installed vertically or horizontally, the movable buckle can achieve stable suspension or friction locking fixation through a spiral coiled tail, which can be quickly disassembled and installed. This expands the column-shaped combined support rod into other storage forms or platforms, providing more storage contact surfaces or storage fixing points.

[0017] 4. The through connection hole of the female connector bracket matches the protruding connection part and connecting post of the male connector bracket. The female connector bracket and connecting post can be used as a combination connector of the combination strut or as a telescopic connector, which has the advantage of being multifunctional. Moreover, all parts can be processed using the same thread size, which greatly facilitates production and processing. Attached Figure Description

[0019] Specific Implementation Example 1: Please refer to the appendix Figure 1 -Appendix Figure 9 , A modular support frame includes a modular support rod 1, a male modular bracket 11, a female modular bracket 12, a connecting column 13, and a support leg 2.

[0020] The combined support rod 1 is a cylindrical rod, and the two end faces of the combined support rod 1 have a storage cavity 10 opened into the rod along the central axis of the combined support rod 1.

[0021] like Figure 5 As shown, the male connector bracket 11 is a cylindrical part with the same diameter as the combined support rod 1. One end face of the male connector bracket 11 has a protruding connecting portion 111 extending along its central axis. The male connector bracket 11 has four evenly spaced through holes centered on its central axis, surrounding the protruding connecting portion 111. The female connector bracket 12 is a cylindrical part with the same diameter as the combined support rod 1. The female connector bracket 12 has a through connecting hole 121 along its central axis, surrounding the outer side of the through connecting hole 121 with four evenly spaced through holes. The protruding connecting portion 111 and the through connecting hole 121 have the same diameter, and matching threads are formed on the outer peripheral wall of the protruding connecting portion 111 and the inner peripheral wall of the through connecting hole 121. Figure 4As shown, two independent combined support rods 1 are respectively provided with a male combined support bracket 11 and a female combined support bracket 12 at their adjacent ends. Both the male combined support bracket 11 and the female combined support bracket 12 have screws inserted into their respective four through holes to fix them to the ends of the combined support rods 1. Through the threaded engagement of the protruding connecting part 111 and the through connecting hole 121, the ends of the two independent combined support rods 1 can be detachably combined.

[0022] The connecting post 13 is a threaded stud with threads on its outer circumference, and the threads on the outer circumference of the connecting post 13 match the threads through the connecting hole 121. Both ends of the connecting post 13 are cylindrical bodies with diameters smaller than the thread diameter, and the surfaces of the cylindrical bodies have smooth walls. Figure 9 As shown, the connecting post 13 also has annular grooves on the outer periphery of both ends, and the annular anti-disengagement buckle 21 is embedded and engaged in the groove. Figure 6 As shown, each of the two independent combined support rods 1 has a female combined bracket 12 at its adjacent ends. Each female combined bracket 12 has screws inserted into its four through holes to fix it to the end of the combined support rod 1. The two ends of the connecting post 13 are threadedly connected to the female combined brackets 12 on both sides. The two ends of the connecting post 13 are screwed into the receiving cavity 10, allowing for a detachable combined connection between the ends of the two independent combined support rods 1. The outer diameter of the anti-disengagement buckle 21 is larger than the diameter of the through connecting hole 121, preventing the connecting post 13 from rotating and loosening.

[0023] The support leg 2 consists of a connecting column 13 and a support plate 20, the support plate 20 including an abutment plate 201 and a locking plate 202. Figure 7 As shown, the abutment plate 201 and the fastening plate 202 are disc-shaped parts, with their end faces abutting and fitting together. Three screws are evenly spaced around the central axis of the support plate 20, connecting and fixing the abutment plate 201 and the fastening plate 202 into a whole. Non-penetrating cavities are formed on both sides of the center of the abutment surfaces of the abutment plate 201 and the fastening plate 202, creating a limiting cavity 203 inside the support plate 20. A through hole with a diameter matching the diameter of the end of the connecting post 13 is formed in the center of the fastening plate 202, connecting to the limiting cavity 203. Figure 8 As shown, the smaller diameter rod end on the right side of the connecting post 13 extends into the limiting cavity 203 through the through hole in the center of the fastening disc 202. An anti-disengagement buckle 21 is embedded in the smaller diameter rod end of the connecting post 13. The outer diameter of the anti-disengagement buckle 21 is larger than the diameter of the through hole in the center of the fastening disc 202. The smaller diameter rod end of the connecting post 13 is locked and fixed in the limiting cavity 203. Figure 3As shown, one or two independent female connector brackets 12 can be selectively screwed onto the other end of the connecting column 13, and a snap-fit ​​anti-disengagement buckle 21 is embedded at the end of the rod to prevent the female connector bracket 12 from unscrewing and falling off. The female connector bracket 12 is fixedly connected to the end of the combined support rod 1 by screws inserted in four through holes (if two female connector brackets 12 are provided, the female connector bracket 12 closer to the left end of the rod is screwed to the end of the combined support rod 1), so that the support leg 2 composed of the connecting column 13 and the support plate 20 is combined with the combined support rod 1 as one unit. By adjusting the length of the left end of the connecting column 13 screwed into the storage cavity 10, the reciprocating extension and retraction movement of the support leg 2 along the axial direction can be realized.

[0024] Installation and usage principles: Two independent combined struts 1 are connected by male combined brackets 11 and female combined brackets 12 at adjacent ends, and each end of the strut not used for connection is connected to a support leg 2. Figure 2 As shown, in the horizontal installation state, two independent female connector brackets 12 are screwed onto the connecting rod 13 of the right support leg 2. In the vertical installation state, two independent female connector brackets 12 are screwed onto the connecting rod 13 of the lower support leg 2. Taking the horizontal installation state as an example, select a space with two vertical parallel support surfaces (such as between two walls), place the left support leg 2 against the left support surface, rotate and adjust the connecting rod 13 of the right support leg 2, and rotate the connecting rod 13 to the right so that the right support leg 2 abuts against the left support surface. Then rotate the independent female connector bracket 12 on the right connecting rod 13 so that it abuts against the female connector bracket 12 screwed to the combined support rod 1, forming a double nut anti-loosening, and stretch the entire combined support rod frame between the two side walls for subsequent hanging of clothes, etc.

[0025] Disassembly and assembly principle: For Figure 1 or Figure 2 The main body is extended by a combined support frame consisting of two independent combined struts 1. The support plate 20 of one side support leg 2 can be removed, and the end of the empty connecting column 13 can be combined and connected with another combined strut 1 with a female combined bracket 12 installed at the end, thus extending the overall length of the combined support frame to suit installation scenarios with larger spans.

[0026] For Figure 1 or Figure 2 The main body is a combined support frame consisting of two independent combined struts 1. It can be shortened and can be disassembled from the connection between the male combined bracket 11 and the female combined bracket 12 in the middle. The end of any one of the independent combined struts 1 can be replaced with a support leg 2 for use in installation scenarios with smaller spans.

[0027] Specific Implementation Example 2: Please refer to the appendix Figures 10-11 , Based on the first specific embodiment, it also includes a movable buckle 3, which is made by bending a rod. One end of the movable buckle 3 is bent to form a spiral tail 31. The spiral pitch and diameter of the spiral tail 31 are both greater than the diameter of the combined support rod 1. The spiral tail 31 can be deflected from the gap position of the spiral and hung on the combined support rod 1. The other end of the movable buckle 3 can be bent to form a ring-shaped storage frame.

[0028] like Figure 10 As shown, when the combined support frame is installed in an upright state, the coiled tail 31 of the movable buckle 3 encircles the outer periphery of the combined support rod 1, and the other end of the movable buckle 3 is bent into a storage frame, which can be used as... Figure 1 As shown, containers such as basins and baskets are placed in the frame. The gravity at the end of the frame will generate a deflection torque on the end of the coiled tail 31. Under the action of the deflection torque, the inner spiral of the coiled tail 31 will be tilted and pressed against the outer edge of the combined support rod 1. The inner surface of the coiled tail 31 generates a corresponding vertical friction force with respect to the outer surface of the combined support rod 1 to fix the movable buckle 3.

[0029] like Figure 11 As shown, when the combined support rod frame is installed in a horizontal state, the coiled tail 31 of the movable buckle 3 can be stably coiled and hung on the outer periphery of the combined support rod 1. The other end of the movable buckle 3 is bent into a storage frame to provide more different types of hanging storage points.

[0030] Specific Implementation Example 3: Please refer to the appendix Figure 12 -Appendix Figure 13 , Based on the first specific embodiment, a locking disc 14 is added to replace the female joint bracket 12 that locks the support leg 2 about the axial movement of the combined support rod 1.

[0031] like Figure 13 As shown, the locking disc 14 is a cylindrical part. The outer periphery of the locking disc 14 has a radially extending anti-slip part 141. The central axis of the locking disc 14 has a through threaded hole that matches the connecting post 13. One end face of the locking disc 14 has a cylindrical recessed cavity 142.

[0032] Installation and usage principles: like Figure 12 As shown, during installation, the locking disc 14 is threadedly connected to the connecting post 13 at the support leg 2. The locking disc 14 is also separated from the female connector bracket 12 at the end of the combined support rod 1 by screws. The end face of the locking disc 14 with the recessed cavity 142 faces the adjacent female connector bracket 12. A spring is sleeved on the outside of the connecting post 13 located between the locking disc 14 and the female connector bracket 12. One end of the spring abuts against the end face of the female connector bracket 12, and the other end abuts against the bottom surface of the recessed cavity 142.

[0033] In use, simply rotate the locking disc 14 close to the female connector assembly bracket 12 to compress the spring between them. The axial thrust applied by the spring to both sides provides axial preload to the female connector assembly bracket 12 and the locking disc 14, which are threaded to the connecting column 13 on both sides. This achieves the function of preventing loosening of the threaded connection. Compared with the double nut anti-loosening structure formed by the two female connector assembly brackets 12 in Embodiment 1, it is easier to lock and can avoid the situation where it is difficult to loosen after locking. It allows users to more conveniently apply or release the axial preload anti-loosening force at the threaded connection.

[0034] The above description is only a preferred embodiment of the present utility model and is intended to illustrate the principle and effect of the present utility model, and is not intended to limit the present utility model. All variations, modifications and substitutions within the spirit and principle of the present design are within the protection scope of the present utility model.
