Description

Technical Field

[0001] This utility model relates to the field of modular connection technology, specifically a parametric 3D printing assembly node. Background Technology

[0002] In the field of modular connection technology, traditional assembly nodes usually adopt a fixed structure or a single specification of connection interface, which is difficult to be compatible with different pipe diameters and fittings. Frequent replacement of the whole component is required, resulting in low installation efficiency. In addition, traditional nodes need to be prefabricated in multiple specifications for multi-specification threaded connection needs. For example, the connection of pipe fittings of different diameters requires the availability of node components of multiple specifications, increasing inventory and management costs.

[0003] Therefore, a parametric 3D printing assembly node is proposed to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a parametric 3D printed assembly node, which has advantages such as parametric multi-specification integration, rapid selection of different specifications, assisted precise positioning, and reliable locking mechanism. It solves the problems of traditional assembly nodes, which usually use fixed structures or single-specification connection interfaces, making it difficult to be compatible with pipe fittings of different diameters, requiring frequent replacement of the whole component, resulting in low installation efficiency. In addition, traditional nodes need to be prefabricated in multiple specifications for multi-specification threaded connection needs, such as the connection of pipe fittings of different diameters, requiring multiple specifications of node components, increasing inventory and management costs.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A parametric 3D printing assembly node includes a perforated base. The front side of the perforated base is fixedly connected to spokes that are symmetrically distributed on the left and right sides. The interior of the spokes is fixedly connected to the same internal hexagonal sleeve. The interior of the internal hexagonal sleeve is slidably connected to hexagonal prisms extending to its left and right sides. The outer side of the internal hexagonal sleeve is provided with a 3D printing assembly node rotatably connected to it. The 3D printing assembly node includes a fan-shaped mounting block, an internal threaded cylinder, a columnar hole, and a circular groove. The outer side of the left end of the hexagonal prism is provided with an elastic reset component that abuts against the left side of the internal hexagonal sleeve. The outer side of the right end of the hexagonal prism is provided with a locking and limiting component adapted to the columnar hole. The top of the left spoke is provided with a positioning auxiliary component adapted to the circular groove.

[0008] The beneficial effects of this utility model are:

[0009] This parametric 3D printing assembly node fixes the perforated base to the wall surface with bolts. Pressing the left end of the hexagonal prism causes the locking and limiting component to separate from the columnar hole, while simultaneously compressing the elastic reset component. The fan-shaped mounting block rotates according to the pipe specifications, causing the matching internal threaded cylinder to rotate to the installation position. During this process, the positioning auxiliary component engages with the circular groove. Each time the internal threaded cylinder of a specific size is rotated, the positioning auxiliary component springs into the circular groove, providing a tactile feedback for rotating the fan-shaped mounting block, facilitating the positioning of the internal threaded cylinder during rotation. When the positioning auxiliary component is within the circular groove, the locking and limiting component aligns with the columnar hole, releasing the left end of the hexagonal prism. The elastic reset component then returns to its original shape, causing the locking and limiting component to reset and insert into the columnar hole, locking and limiting the rotated fan-shaped mounting block. The pipe can then be screwed into the internal threaded cylinder for installation. This system offers advantages such as parametric multi-specification integration, rapid selection of different specifications, precise positioning assistance, and a reliable locking mechanism.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, the elastic reset assembly includes a spacer and a reset spring. A spacer located on the left side of the inner hexagonal sleeve is fixedly connected to the outer side of the left end of the hexagonal prism. A reset spring sleeved on the outer side of the hexagonal prism is provided between the right side of the spacer and the left side of the inner hexagonal sleeve.

[0012] Furthermore, the right side of the fan-shaped mounting block is provided with columnar holes arranged in a ring array, and the included angle between the axes of adjacent columnar holes is the same as the included angle between the axes of adjacent internal threaded cylinders.

[0013] Furthermore, the locking and limiting assembly includes a sector plate and ball-head columns. The sector plate is fixedly connected to the outer side of the right end of the hexagonal prism, and the ball-head columns, which are arranged in a circular array and extend into the columnar hole, are fixedly connected to the left side of the sector plate. The included angle between the axes of adjacent ball-head columns is the same as the included angle between the axes of adjacent columnar holes.

[0014] The beneficial effect of adopting the above-mentioned further solution is that pressing the left end of the hexagonal prism causes the sector plate and ball head column to move. At the same time, the hexagonal prism drives the spacer to compress the return spring, so that the ball head column and the columnar hole release the locking limit on the sector mounting block. This allows the sector mounting block to rotate and select an internal threaded cylinder that matches the pipe fitting, achieving rapid selection. Releasing the left end of the hexagonal prism allows the return spring to restore its deformation and push the hexagonal prism to reset through the spacer. At the same time, the sector plate drives the ball head column to move, so that all the ball head columns are inserted into the columnar hole, locking and limiting the rotation of the sector mounting block. Several ball head columns ensure the structural strength of the sector mounting block and the internal hexagonal sleeve after the limit is set, preventing the sector mounting block from deflecting.

[0015] Furthermore, a sector-shaped mounting block is rotatably connected to the outer side of the internal hexagonal sleeve. Several sets of internally threaded cylinders of different specifications are provided on the periphery of the sector-shaped mounting block. Each set of internally threaded cylinders consists of two fixed internally threaded cylinders of the same specification. The included angle between the axes of the two internally threaded cylinders in the same set is 90°.

[0016] Furthermore, the left side of the fan-shaped mounting block is provided with circular grooves arranged in a ring array and the number of grooves is the same as the number of internal threaded cylinder groups. The included angle between the axes of adjacent circular grooves is the same as the included angle between the axes of adjacent internal threaded cylinders. The positions of the circular grooves are adapted to the positions of internal threaded cylinders of different specifications.

[0017] Furthermore, the positioning auxiliary component includes a vertical plate, a cylindrical shell, a ball-head rod, and a spring. The top of the left-side spoke is fixedly connected to the vertical plate, and the top of the vertical plate is fixedly connected to the cylindrical shell. The cylindrical shell has a ball-head rod extending to its right side and adapted to a circular groove inside. The left side of the ball-head rod has a spring located inside the cylindrical shell.

[0018] The beneficial effect of adopting the above-mentioned further solution is that, during the rotation of the sector-shaped mounting block, each time it rotates to the internal threaded cylinder of a certain size, the ball head rod will spring into the circular groove under the action of the spring, providing a sense of jerk when rotating the sector-shaped mounting block, so as to facilitate the positioning of the internal threaded cylinder during the rotation of the sector-shaped mounting block. When the ball head rod is in the circular groove, the ball head is aligned with the columnar hole, so that when the hexagonal prism is released, the ball head can be inserted into the columnar hole, thus achieving auxiliary precise positioning.

[0019] Furthermore, the left side of the fan-shaped mounting block is marked with the specifications of the internally threaded cylinder, and the specifications are located on the periphery of the circular groove and are respectively adapted to the corresponding internally threaded cylinder.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the specification model is located on the periphery of the circular groove, providing an intuitive visual reference. When the user rotates the fan-shaped mounting block, combined with the tactile feedback provided by the ball joint springing into the circular groove, the user can quickly identify and confirm the internal threaded cylinder of the required target specification.

[0021] Furthermore, the fan-shaped mounting block, the internally threaded cylinder, the columnar hole, and the circular groove are integrally formed by 3D printing.

[0022] The beneficial effects of adopting the above-mentioned further solutions are that the 3D printed integrated fan-shaped mounting block, internal threaded cylinder, columnar hole and circular groove have improved structural strength and reliability. Under vibration or temperature difference environment, the material consistency prevents deformation caused by thermal expansion difference and extends service life. Attached Figure Description

The included angle between the axes of adjacent ball head posts 702 is the same as the included angle between the axes of adjacent columnar holes 503.

[0033] The outer side of the internal hexagonal sleeve 3 is rotatably connected to a fan-shaped mounting block 501. The fan-shaped mounting block 501 has several sets of internal threaded cylinders 502 of different specifications on its periphery. Each set of internal threaded cylinders 502 consists of two fixed internal threaded cylinders 502 of the same specification.

[0034] The left side of the fan-shaped mounting block 501 has circular grooves 504 arranged in a ring array and the number of grooves is the same as the number of sets of internal threaded cylinders 502. The included angle between the axes of adjacent circular grooves 504 is the same as the included angle between the axes of adjacent internal threaded cylinders 502. The opening position of the circular grooves 504 is adapted to the position of internal threaded cylinders 502 of different specifications.

[0035] The positioning auxiliary component 8 includes a vertical plate 801, a cylindrical shell 802, a ball head rod 803, and a spring 804.

[0038] Working principle:

[0039] Step 1: Fix the perforated base 1 to the wall surface with bolts, press the left end of the hexagonal prism 4, and then drive the sector plate 701 and the ball head column 702 to move. At the same time, the hexagonal prism 4 drives the partition 601 to compress the return spring 602, so that the ball head column 702 and the columnar hole 503 release the locking limit on the sector mounting block 501.

[0040] Step 2: Rotate the sector-shaped mounting block 501 to select the internal threaded cylinder 502 that is compatible with the pipe fitting.

[0041] Step 3: After selecting the internal threaded cylinder 502, when the ball head rod 803 is in the circular groove 504, the ball head pins 702 are all aligned with the columnar holes 503. Loosen the left end of the hexagonal prism 4, and the return spring 602 restores its deformation and pushes the hexagonal prism 4 to reset through the partition plate 601. At the same time, the ball head pins 702 are moved by the sector plate 701, so that the ball head pins 702 are all inserted into the columnar holes 503. Lock and limit the rotated sector mounting block 501, and the pipe can be screwed into the internal threaded cylinder 502 for installation.
