Description

Technical Field

[0001] This utility model relates to the field of holiday decorations technology, specifically a steel pipe frame Christmas tree with an easy-to-disassemble base. Background Technology

[0002] In the field of holiday decorations, Christmas trees are a core decorative element, and the ease of assembly and storage has always been a key concern for users. Traditional steel pipe frame Christmas tree bases often use threaded connections and snap-fit ​​splicing methods, which can achieve the function of fixing, but in actual operation, they often face problems such as cumbersome disassembly and assembly steps, easy loss of parts, and wear and tear due to repeated operation. Especially in the scenario of concentrated arrangement and storage before and after the holidays, not only does it consume a lot of time, but improper operation may also cause the base connection to loosen, affecting the overall stability of the Christmas tree.

[0003] Chinese patent CN210643632U discloses an easily assembled Christmas tree, including Christmas tree leaves. A Christmas tree connecting rod is fixedly connected inside each leaf, and a Christmas tree base is fixedly installed at the bottom end of the connecting rod. A snap-fit ​​device is fixedly connected to the bottom surface of the connecting rod, which abuts against a secondary connecting rod. A slot is formed inside the top of the secondary connecting rod, and an arc-shaped groove is formed inside the secondary connecting rod. A fixing screw is threaded onto the surface of the Christmas tree base, and a locking groove is formed inside the base. This easily assembled Christmas tree features a connecting rod that is inserted into the slot and fixed by rotating it. The arc-shaped groove holds the connecting rod in place. After assembly, it can be easily moved using rollers. This saves both time and effort.

[0004] However, the Christmas tree that is easy to assemble mentioned above relies on a "fixing screw" to fix the Christmas tree base and the secondary connecting rod. Although this threaded connection method can provide a certain fixing effect, it continues the inherent defects of the traditional threaded structure, which often leads to problems such as cumbersome disassembly and assembly steps, easy loss of parts, and easy wear and tear from repeated operation in actual operation. Utility Model Content

[0005] The purpose of this utility model is to provide a steel pipe frame Christmas tree with an easy-to-disassemble base, so as to solve the problems of complicated disassembly and assembly steps, easy loss of parts, and easy wear and tear caused by repeated operation due to the threaded connection method mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A steel pipe frame Christmas tree with an easy-to-assemble and disassemble base includes a support plate; the support plate has an annular limiting groove, and a locking mechanism is rotatably assembled in the annular limiting groove; the upper surface of the support plate has multiple sets of insertion slots at equal intervals, all of which are connected to the annular limiting groove and located on the outer side of the locking mechanism; the insertion slots can be used for sliding insertion plates, and the upper surface of the insertion plates is fixedly assembled with the Christmas tree frame.

[0007] The aforementioned steel pipe frame Christmas tree with easy base assembly and disassembly includes a toothed groove on one end of the inner side of the insert plate. The toothed groove allows the insert plate inserted into the groove to move the toothed groove and the locking mechanism to be positioned opposite each other. The locking mechanism can be rotated to achieve sliding engagement with the toothed groove, thereby locking the Christmas tree frame.

[0008] The aforementioned steel pipe frame Christmas tree with an easily detachable base includes a locking mechanism comprising a limiting plate; the limiting plate is rotatably mounted in an annular limiting groove, and a connecting post is fixedly mounted on the upper surface of the limiting plate, the connecting post being located at the center of multiple sets of insertion slots; multiple sets of insertion teeth are fixedly mounted equidistantly on the outer surface of the connecting post, all of the multiple sets of insertion teeth being located within an embedded groove; the embedded groove is embedded in the outer periphery of the annular limiting groove.

[0009] The aforementioned steel pipe frame Christmas tree, which facilitates the assembly and disassembly of its base, features multiple sets of insert teeth located within an inner groove. The spacing between adjacent sets of insert teeth is perpendicular to the insertion groove. This spacing allows the Christmas tree frame to drive the insert plate into the insertion groove. When the insert plate is inserted into the spacing between adjacent sets of insert teeth, the connecting column can rotate to move multiple sets of insert teeth out of the inner groove and achieve a sliding fit with the tooth groove.

[0010] The aforementioned steel pipe frame Christmas tree with easy base assembly and disassembly includes a toggle rod fixedly mounted on the outer surface of the limiting plate; the toggle rod passes through the toggle groove and extends to the outer periphery of the support plate; the toggle groove is opened at one end of the outer surface of the support plate and is connected to the annular limiting groove.

[0011] The aforementioned steel pipe frame Christmas tree with an easily detachable base includes a torsion groove on the lower surface of the limiting plate, within which a spring is fitted. The upper end of the spring is fixedly connected to the inner top of the torsion groove, and the lower end of the spring is fixedly connected to the lower surface of the annular limiting groove. The spring applies a torsional force to the limiting plate and the connecting column, ensuring that the connecting column's multiple sets of inserts on its outer surface remain in a mating position with the toothed grooves of the insert plate. When the inserts are inserted into the toothed grooves, the insert plate drives the actuating rod to slide along the actuating groove until the actuating rod abuts against the end of the actuating groove, thereby blocking and limiting the actuating rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are: Through the coordinated operation of the lever, spring, insert teeth, and tooth groove, the system achieves the functions of "tool-free quick disassembly and assembly + automatic stable locking". Assembly only requires three steps: "leverage to avoid obstruction - insert alignment - release and lock". This completely solves the cumbersome problems of repeated rotation of traditional threads and easy jamming of buckles. The lever groove limit can intuitively confirm that the lock is in place, preventing hidden loosening. At the same time, there are no scattered small parts, which can meet the needs of both home and commercial scenarios, greatly improving the convenience and economy of use.

[0015] 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.

[0016] Please see Figures 1-4 This embodiment provides the following technical solution: like Figures 1-2As shown, a steel pipe frame Christmas tree with an easy-to-assemble and disassemble base includes a support plate 101; an annular limiting groove 105 is provided in the support plate 101, and a locking mechanism 2 is rotatably assembled in the annular limiting groove 105; multiple sets of insertion slots 107 are provided at equal intervals on the upper surface of the support plate 101, and the multiple sets of insertion slots 107 are all connected to the annular limiting groove 105 and located on the outer side of the locking mechanism 2; the insertion slots 107 can be used for the insertion plate 103 to slide into and engage, and the Christmas tree frame 1 is fixedly assembled on the upper surface of the insertion plate 103, and a toothed groove 104 is provided on one end of the inner side of the insertion plate 103; the toothed groove 104 is provided so that the insertion plate 103 inserted into the insertion slot 107 can drive the toothed groove 104 to be arranged opposite to the locking mechanism 2, and the locking mechanism 2 can achieve sliding engagement with the toothed groove 104 by rotation, so as to achieve locking of the Christmas tree frame 1.

[0017] Through the design of the Christmas tree frame 1, support plate 101, insert plate 103, toothed groove 104, insert slot 107, and locking mechanism 2, during assembly and use, firstly, the support plate 101 is placed stably in the position to be used. Then, the locking mechanism 2 is pushed to rotate from the insert slot 107 into the inner groove 106 for avoidance. Next, the user can pick up the Christmas tree frame 1 and align the bottom insert plate 103 with the corresponding insert slot 107 on the support plate 101, and then move along the insert slot 107. Extending in the direction, the insert plate 103 is slid into the insert slot 107 until all the Christmas tree frames 1 are inserted through the insert plate 103. Then, the toothed groove 104 on one end of the insert plate 103 will align with the locking mechanism 2 in the annular limiting groove 105. At this point, the push on the locking mechanism 2 can be released, allowing the locking mechanism 2 to automatically rotate within the annular limiting groove 105 through the resetting torsional force and gradually slide into the toothed groove 104 of the insert plate 103. When the locking mechanism 2 is fully inserted... After the insert plate 103 slides into the toothed groove 104 and fits tightly against the inner wall of the toothed groove 104, it is fixed in place, thereby locking the Christmas tree frame 1 and allowing the Christmas tree frame 1 to be stably installed on the support plate 101. When it is necessary to remove the base, simply rotate the locking mechanism 2 in the opposite direction to slide the locking mechanism 2 out of the toothed groove 104, release the limitation on the insert plate 103, and then pull the insert plate 103 out of the insert groove 107, thus realizing the connection between the Christmas tree frame 1 and the support plate 101. Separating the disc 101 completes the disassembly of the base, allowing for assembly to be done in just three steps: "pushing the locking mechanism 2 to avoid obstruction → aligning the insert plate 103 with the slide → releasing the locking mechanism 2 to automatically lock." Disassembly requires only two steps: "reverse rotation of the locking mechanism 2 → pulling out the insert plate 103." No screwdrivers, wrenches, or other professional tools are needed throughout the process. Whether it's the elderly, children, or non-professional users, everyone can quickly get started, completely solving the tedious problems of traditional threaded connections requiring repeated rotation and snap-fit ​​connections requiring precise alignment.

[0018] like Figures 3-4As shown, the locking mechanism 2 includes a limiting plate 203; the limiting plate 203 is rotatably mounted in the annular limiting groove 105, and a connecting post 201 is fixedly mounted on the upper surface of the limiting plate 203. The connecting post 201 is located at the center of multiple sets of insertion grooves 107; multiple sets of insert teeth 202 are fixedly mounted on the outer surface of the connecting post 201 in an equidistant manner, and the multiple sets of insert teeth 202 are all located in the inner groove 106; the inner groove 106 is embedded in the outer periphery of the annular limiting groove 105.

[0019] The multiple sets of insert teeth 202 located in the inner groove 106 are arranged perpendicularly to the insertion groove 107 by the spacing between two adjacent sets of insert teeth 202. This spacing is designed to allow the Christmas tree frame 1 to drive the insertion plate 103 to be inserted into the insertion groove 107. When the insertion plate 103 is inserted into the spacing between two adjacent sets of insert teeth 202, the connecting post 201 can rotate to drive the multiple sets of insert teeth 202 out of the inner groove 106 and achieve sliding engagement with the tooth groove 104. The outer surface of the limiting plate 203 is fixedly equipped with a toggle rod 204. The toggle rod 204 passes through the toggle groove 102 and extends to the outer periphery of the support plate 101. The toggle groove 102 is opened at one end of the outer surface of the support plate 101 and is connected to the annular limiting groove 105.

[0020] The lower surface of the limiting plate 203 is provided with a torsion groove 205, and a spring 206 is installed in the torsion groove 205. The upper end of the spring 206 is fixedly connected to the inner top of the torsion groove 205, and the lower end of the spring 206 is fixedly connected to the lower surface of the annular limiting groove 105. The spring 206 can be used to apply a torsional force to the limiting plate 203 and the connecting post 201, so that the connecting post 201 can drive the multiple sets of insert teeth 202 on its outer surface to always maintain the insertion and engagement state with the tooth groove 104 of the insert plate 103. When the insert teeth 202 are inserted into the tooth groove 104, the insert plate 103 can drive the actuating rod 204 to slide along the actuating groove 102 until the actuating rod 204 abuts against the end of the actuating groove 102, so as to realize the blocking and limiting of the actuating rod 204.

[0021] Through the design of the connecting post 201, the insert teeth 202, the actuating rod 204, the torsion groove 205, and the spring 206, during assembly, the user can move the actuating rod 204 extending from the torsion groove 102 to drive the limiting plate 203 to rotate within the annular limiting groove 105. During this process, the limiting plate 203 will also drive the insert teeth 202 on the outer surface of the connecting post 201 to rotate into the inner groove 106 to avoid the insertion groove 107. The rotating connecting post 201 will then... The internally installed spring 206 is twisted by the torsion groove 205 on the lower surface. The twisted spring 206 applies a torsional restoring force to the connecting post 201. Then, the Christmas tree frame 1 can be picked up, causing the bottom insert plate 103 to align with the insert slot 107 and slide in, positioning it between the two sets of recessed slots 106. Subsequently, the lever 204 can be released. At this time, the spring 206 in the torsion groove 205 on the lower surface of the limiting plate 203 will release its torsional force, causing the connecting post 201 to rotate. This causes the insert 202 to move out of the inner groove 106 and slide into the tooth groove 104 inside the insert plate 103. At the same time, the limiting plate 203 will drive the actuating rod 204 to slide in the actuating groove 102 until the actuating rod 204 slides to the end of the actuating groove 102 and is blocked and limited, so that the insert 202 is always inserted in the tooth groove 104, thus completing the locking of the Christmas tree frame 1. When disassembly is required, the actuating rod 204 is turned in the opposite direction, causing the limiting plate 203 and the connecting post 201 to rotate in the opposite direction. The spring 206 is twisted and stores force, the insert 202 disengages from the tooth groove 104 and returns to the inner groove 106, and then the insert plate 103 is pulled out from the insert groove 107, thus separating the Christmas tree frame 1 from the support plate 101. In the entire connection structure between the support plate 101 and the Christmas tree frame 1, there are no screws, clips or other small scattered parts. After disassembly and assembly, only two types of parts need to be stored: the support plate 101 and the Christmas tree frame 1. There is no need to worry about small parts being lost and causing subsequent assembly difficulties, thus reducing the difficulty of storage.

[0022] Based on the above technical solution, the working steps of this solution are summarized as follows: During assembly, the user can move the lever 204 extending from the lever groove 102 to drive the limiting plate 203 to rotate within the annular limiting groove 105. During this process, the limiting plate 203 will also drive the insert teeth 202 on the outer surface of the connecting column 201 to rotate into the inner groove 106 to avoid the insertion groove 107. The rotating connecting column 201 will also twist the internally installed spring 206 through the torsion groove 205 on its lower surface. The torsion spring 206 can then apply a torsional restoring force to the connecting column 201. Then, the Christmas tree frame 1 can be picked up, causing the bottom insertion plate 103 to align with the insertion groove 107 and slide into it so that it is between the two sets of inner grooves 106. Afterward, the lever 204 can be released, at which point the limiting plate 203 will rotate within the annular limiting groove 106. The spring 206 in the torsion groove 205 on the lower surface of 03 releases torsion force, causing the connecting post 201 to rotate. This causes the insert 202 to move out of the inner groove 106 and slide into the tooth groove 104 on the inner side of the insert plate 103. At the same time, the limiting plate 203 will drive the actuating rod 204 to slide in the actuating groove 102 until the actuating rod 204 slides to the end of the actuating groove 102 and is blocked and limited, so that the insert 202 is always inserted in the tooth groove 104, thus locking the Christmas tree frame 1. When disassembly is required, the actuating rod 204 is reversed, causing the limiting plate 203 and the connecting post 201 to rotate in the opposite direction. The spring 206 is torsionally charged, and the insert 202 is dislodged from the tooth groove 104 and returns to the inner groove 106. Then, the insert plate 103 is pulled out from the insert groove 107, thus separating the Christmas tree frame 1 from the support plate 101.

[0023] In summary, assembling a Christmas tree requires only three steps: "pushing the locking mechanism 2 to avoid obstacles → aligning the insert plate 103 with the slide → releasing the locking mechanism 2 to automatically lock it in place." Disassembly requires only two steps: "reverse rotation of the locking mechanism 2 → pulling out the insert plate 103." No professional tools such as screwdrivers or wrenches are needed throughout the process, significantly improving setup efficiency.

Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
