Description

Technical Field

[0001] This utility model relates to the field of aluminum profile assembly technology, specifically to a weld-free assembled aluminum profile. Background Technology

[0002] In the background technology of industrial profile assembly, weld-free assembled aluminum profiles are a type of standardized component that differs from traditional welded aluminum profiles. They are made of aluminum alloy as the base material through extrusion molding and have pre-set mechanical connection structures such as slots, snap blocks, threaded pairs, and locking mechanisms on the profile body or matching connectors. They can achieve rapid splicing, combination, and disassembly between multiple aluminum profiles without the need for irreversible connection methods such as welding and riveting.

[0003] Currently available weld-free aluminum profiles mostly use simple slot insertion or single bolt fastening structures. Either they require additional tools such as wrenches to complete the installation and disassembly, making the operation cumbersome and the assembly inefficient, or the snap-fit ​​structure lacks elastic buffer design, making it easy to loosen and shift when subjected to external vibration and impact, making it difficult to maintain a stable connection in the long term. In addition, although some weld-free structures simplify the operation process, they lack an effective secondary positioning and reinforcement mechanism, relying only on single snap-fit ​​or bolt fixing, resulting in limited connection strength and making them susceptible to external impacts that affect the firmness of the installation.

[0004] Therefore, this utility model proposes a weld-free assembled aluminum profile to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a weld-free assembled aluminum profile to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a weld-free assembled aluminum profile, comprising a combination block and a base, wherein the base is fixedly installed at the center of the bottom inner side of the combination block.

[0007] A mounting plate is movably attached to the center of the top of the assembly block. A knob is rotatably mounted on the top of the mounting plate, and a rotating rod is fixedly connected to the bottom of the knob.

[0008] A positioning cylinder is fixedly installed on the top of the base. A protrusion is fixedly sleeved on the outer surface of the bottom of the rotating rod. A pressing block is telescopically sleeved around the outer surface of the positioning cylinder. A buffer spring is fixedly connected to one side of the surface of the pressing block. A sleeve rod is fixedly installed on one side of the surface of the buffer spring. A connecting rod is fixedly connected to one side of the surface of the sleeve rod. A locking block is fixedly connected to one side of the surface of the connecting rod. A locking groove is opened on the surface of the locking block.

[0009] Preferably, the top surface of the assembly block has insertion holes around its perimeter, the bottom inner side of the assembly block has sleeves fixedly installed around its perimeter, and the surface of the connecting rod has positioning holes.

[0010] Preferably, a locking rod is movably engaged at the insertion hole position. The locking rod passes through the insertion hole and the positioning hole, and is engaged with the corresponding part of the sleeve.

[0011] Preferably, the locking block extends to the perimeter of the outer surface of the assembly block via the connecting rod, and the locking block is engaged with the surface of the aluminum profile.

[0012] Preferably, the rotating rod rotates at the center position inside the assembly block via a knob, and the rotating rod is sleeved on the top of the positioning cylinder from top to bottom and extends into the inside of the positioning cylinder for adjustment.

[0013] Preferably, the extrusion block extends to the inside of the positioning cylinder through a buffer spring, and the protrusion block rotates synchronously inside the positioning cylinder through a rotating rod. The surfaces of the protrusion block and the extrusion block are parallel. When the protrusion block rotates, it contacts the surface of the extrusion block, and the extrusion block is adjusted to extend and retract around the surface of the positioning cylinder through the buffer spring.

[0014] Preferably, the extrusion block extends and retracts around the surface of the positioning cylinder, and the synchronous locking block extends and retracts around the outer surface of the combined block through the sleeve rod and connecting rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are: The weld-free assembled aluminum profile proposed in this utility model allows for synchronous rotation of a rotating rod by turning a knob on the top of the mounting plate. The protrusions on the rotating rod rotate along with the rod, pressing against the pressing blocks around the positioning cylinder. The elastic force of the buffer spring causes the sleeve rod, connecting rod, and locking blocks to extend and retract around the outer surface of the assembly block, allowing the locking blocks to quickly and firmly engage with the aluminum profile. Turning the knob in the opposite direction releases the engagement. This convenient operation requires no additional tools, improving assembly and disassembly efficiency. The slots on the locking block surface further enhance the engagement with the pressing blocks, and combined with the buffer spring's cushioning effect, effectively prevent loosening of the connection due to vibration or external impact after assembly, ensuring the stability and reliability of the overall structure. The insertion hole on the top of the assembly block mates with the positioning holes on the inner sleeve and connecting rod, achieving secondary positioning and fixation through the through-hole locking rod, further strengthening the connection and preventing component displacement.

[0018] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Please see Figures 1-2 A weld-free assembled aluminum profile includes a combination block 100 and a base 200, with the base 200 fixedly installed at the center of the bottom inside the combination block 100.

[0020] A mounting plate 101 is movably latched at the top center of the assembly block 100. A knob 102 is rotatably mounted on the top of the mounting plate 101, and a rotating rod 105 is fixedly connected to the bottom of the knob 102.

[0021] The rotating rod 105 rotates at the center position inside the assembly block 100 via the knob 102. The rotating rod 105 is sleeved on the top of the positioning cylinder 201 from top to bottom and extends into the inside of the positioning cylinder 201, where it rotates and adjusts.

[0022] In use, the base 200 at the center of the bottom of the inner side of the assembly block 100 provides stable support. The mounting plate 101, which is movably snapped into the center of the top of the assembly block 100, provides a mounting platform for the knob 102. When the knob 102 on the top of the mounting plate 101 is rotated, the knob 102 will drive the rotating rod 105, which is fixedly connected at the bottom, to rotate synchronously at the center of the interior of the assembly block 100. The rotating rod 105 is sleeved on the top of the positioning cylinder 201 from top to bottom and extends into the interior of the positioning cylinder 201, thereby completing the rotation adjustment inside the positioning cylinder 201, providing a power basis for the subsequent extension and retraction of the snap-fit ​​components and realizing the welding-free assembly of aluminum profiles.

[0023] Please see Figure 3A positioning cylinder 201 is fixedly installed on the top of the base 200. A protrusion 206 is fixedly sleeved on the bottom outer surface of the rotating rod 105. A pressing block 209 is telescopically sleeved around the outer surface of the positioning cylinder 201. A buffer spring 208 is fixedly connected to one side of the surface of the pressing block 209. A sleeve rod 202 is fixedly installed on one side of the surface of the buffer spring 208. A connecting rod 203 is fixedly connected to one side of the surface of the sleeve rod 202. A locking block 205 is fixedly connected to one side of the surface of the connecting rod 203. A locking groove 207 is opened on the surface of the locking block 205.

[0024] The locking block 205 extends to the periphery of the outer surface of the assembly block 100 via the connecting rod 203, and the locking block 205 is engaged with the surface of the aluminum profile.

[0025] The extrusion block 209 extends to the inside of the positioning cylinder 201 via the buffer spring 208. The protrusion block 206 rotates synchronously inside the positioning cylinder 201 via the rotating rod 105. The protrusion block 206 and the extrusion block 209 are distributed parallel to each other. When the protrusion block 206 rotates, it contacts the surface of the extrusion block 209. The buffer spring 208 drives the extrusion block 209 to extend and retract around the surface of the positioning cylinder 201.

[0026] The extrusion block 209 extends and retracts around the surface of the positioning cylinder 201, and is adjusted around the outer surface of the assembly block 100 by means of the sleeve rod 202 and the connecting rod 203 and the synchronous locking block 205.

[0027] In use, when the rotating rod 105 drives the protruding block 206 on the bottom outer surface to rotate synchronously inside the positioning cylinder 201, the protruding block 206 will contact the surface of the pressing block 209 around the inside of the positioning cylinder 201 and generate a pressing force. Under the action of the pressing force, the pressing block 209 will compress the buffer spring 208 on one side, thereby driving the sleeve rod 202, connecting rod 203 and locking block 205 to extend synchronously to the outer surface of the combined block 100. When the protruding block 206 rotates to separate from the pressing block 209, When the position is reached, the elastic rebound force of the buffer spring 208 will push the extrusion block 209 to reset, thereby pulling the sleeve rod 202, connecting rod 203 and locking block 205 to retract to the inside of the assembly block 100; the locking groove 207 on the surface of the locking block 205 can fit with the surface structure of the extrusion block 209. First, the position of the aluminum profile is aligned with the locking block 205, and by extending and retracting the locking block 205, a firm connection and convenient disassembly with the aluminum profile are achieved, thereby achieving the purpose of welding-free assembly of the aluminum profile.

[0028] Please see Figures 3-4 The top surface of the assembly block 100 has insertion holes 103 around its perimeter, and the bottom inner side of the assembly block 100 has a sleeve 104 fixedly installed around its perimeter. The surface of the connecting rod 203 has positioning holes 204.

[0029] A locking rod is movably engaged at the position of the insertion hole 103. The locking rod passes through the insertion hole 103 and the positioning hole 204, and is engaged with the corresponding part inside the sleeve 104.

[0030] In use, after the locking block 205 is initially engaged with the aluminum profile by adjusting the telescopic movement of the connecting rod 203, in order to further improve the stability of the connection, the positioning passage is formed by the insertion holes 103 on the top surface of the assembly block 100, the positioning holes 204 on the surface of the connecting rod 203, and the sleeves 104 fixedly installed on the bottom inner side of the assembly block 100. The locking rod is inserted from the insertion hole 103, so that it passes through the insertion hole 103 and the positioning hole 204 in sequence, and finally engages with the inside of the sleeve 104. This restricts the displacement of the connecting rod 203 and prevents the locking block 205 from retracting or loosening due to external impact or vibration. This achieves secondary positioning and reinforcement of the aluminum profile connection structure, ensuring the stability and reliability of the overall assembly structure.

[0031] Although embodiments of the present invention 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 the present invention, the scope of which is defined by the appended claims and their equivalents.
