Description

Technical Field

[0001] This utility model belongs to the field of combined support frame technology, and specifically relates to a stable connection structure for a combined support frame. Background Technology

[0002] Modular support frames are widely used in building construction, exhibition setup, and other applications requiring temporary support structures. In use, modular support frames typically combine horizontal and vertical members into a frame structure using various connection methods. Then, through the cooperation of diagonal braces and vertical members, a stable triangular structure is formed, thereby improving the stability of the modular support frame's connection structure.

[0003] During use, workers and some goods move on the modular support frame. When subjected to stress or vibration, the connecting parts may loosen or shift in relative position, potentially causing displacement of horizontal bars, vertical bars, and diagonal braces. This reduces the stability of the modular support frame, posing a risk of collapse under heavy loads. Furthermore, the diagonal braces play a role in distributing forces during use, and their placement needs to be flexible depending on the specific operating conditions to enhance the stability of the modular support frame's connection structure. Utility Model Content

[0004] This utility model provides a stable connection structure for a combined support frame to solve at least one of the above-mentioned technical problems.

[0005] The technical solution adopted by this utility model is as follows: a stable connection structure of a combined support frame, including a frame body constructed by connecting multiple uprights and multiple crossbars, and further including a fixed reinforcing component and a free reinforcing component connected between the uprights. The surface of the uprights is formed with multiple limiting grooves extending along the axial direction of the uprights. The fixed reinforcing component includes a fixed diagonal brace and a sliding fastener. The inner side of the sliding fastener is formed with a protrusion that cooperates with the limiting groove, and the outer side of the sliding fastener is formed with a connecting hole. The end of the fixed diagonal brace is formed with a mating hole that cooperates with the connecting hole.

[0006] In a preferred embodiment, the fixed tie rod includes a first tie rod and a second tie rod connected as a single unit.

[0007] In a preferred embodiment, the first tie rod and the second tie rod are inserted into each other, and the first tie rod and the second tie rod are provided with a plurality of equally spaced fixing holes to fix the first tie rod and the second tie rod with fixing bolts.

[0008] In a preferred embodiment, the first tie rod and the second tie rod are connected by a sleeve, the connecting ends of the first tie rod and the second tie rod are formed with external threads, and the inner side of the sleeve is formed with internal threads that mesh with the external threads.

[0009] In a preferred embodiment, the first tie rod has an axially extending expansion groove, and the outer surface of the second tie rod has an expansion protrusion that mates with the expansion groove.

[0010] In a preferred embodiment, the free reinforcing component includes a free diagonal brace and a butterfly fastener. The butterfly fastener includes a first clip and a second clip that are rotatably connected. The inner side of the first clip has a protrusion that mates with the limiting groove.

[0011] In a preferred embodiment, the inner surfaces of the sliding fastener and the first clip are formed with anti-slip textures.

[0012] In a preferred embodiment, the upright has a plurality of equally spaced radially penetrating mounting holes, which cooperate with the connecting holes and the mating holes to connect the fixed diagonal brace to the upright.

[0013] In a preferred embodiment, a fixed connection area is formed between the sliding fastener and the limiting groove, and the end of the crossbar has a pin that extends into the fixed connection area.

[0014] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0015] 1. As a preferred embodiment of this utility model, by utilizing the cooperation of the limiting groove and the protrusion, the movement of the sliding fastener along the circumference of the upright can be restricted, thereby avoiding the deflection of the diagonal tie rod position caused by the force or vibration of the combined support frame, and improving the stability of the combined support frame connection structure.

[0016] 2. As a preferred embodiment of this utility model, by utilizing the combination of fixed reinforcing components and free reinforcing components, the flexibility of the diagonal brace assembly can be improved. This allows for the selection of diagonal braces with different angles, positions, and lengths according to different operating conditions. Furthermore, based on the stress conditions of the entire combined support frame, the load can be selectively distributed to key parts with higher loads, thereby improving the connection stability of the entire combined support frame.

[0017] 3. As a preferred embodiment of this utility model, the first and second diagonal braces have various different connection structures, which can be used to fix the two ends of the fixed diagonal braces to the uprights according to the different length requirements of the fixed diagonal braces and the movement of the sliding fastener along the axis of the upright movement. This allows the horizontal bar to transfer the force to the upright through the diagonal braces when it is under force, thereby dispersing the force. At the same time, during the force transmission process of the diagonal braces, the cooperation of the sliding fastener and the limiting groove can be used to make the sliding fastener connect the upright and the diagonal braces more tightly and prevent the sliding fastener from moving downward.

[0018] 4. As a preferred embodiment of this utility model, the free reinforcing component utilizes the cooperation of the first and second clips on the butterfly fastener to allow the free diagonal brace to have a flexible arrangement angle, thereby serving as an auxiliary diagonal brace to disperse the force on the load-bearing parts and achieving the reinforcement effect on the entire combined support frame connection structure.

[0019] 5. As a preferred embodiment of this utility model, the sliding fastener can cooperate with the crossbar to facilitate the connection between the crossbar and the upright. Attached Figure Description

[0039] In this invention, unless otherwise expressly specified and limited, the first feature "on" or "below" the second feature may be in direct contact with the first and second features, or indirect contact through an intermediate medium. In the description of this specification, references to terms such as "implementation," "example," "aspect," or "specific example" indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of this invention. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0040] A preferred embodiment, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a stable connection structure for a combined support frame includes a frame constructed from multiple uprights 1 and multiple crossbars 2, and further includes fixed reinforcing components 3 and free reinforcing components 4 connected between the uprights 1. Multiple limiting grooves 10 extending axially along the surface of the uprights 1 are formed. The limiting grooves 10 are concave, preferably four in number, and are arranged in a circular array along the circumference of the uprights 1. The limiting grooves 10 increase the surface area of ​​the uprights 1, and their concavity acts as a reinforcing rib, resulting in higher mechanical strength compared to cylindrical uprights 1.

[0041] Furthermore, the fixing and reinforcing component 3 includes a fixing diagonal brace 31 and a sliding fastener 32. The inner side of the sliding fastener 32 has a protrusion 320 that mates with the limiting groove 10. The protrusion 320 can be cylindrical, triangular, or directly fit the shape of the limiting groove 10. The outer side of the sliding fastener 32 has a connecting hole 321, and the end of the fixing diagonal brace 31 has a mating hole 310 that mates with the connecting hole 321. In use, the sliding fastener 32 is connected to the upright 1, and then both ends of the fixing diagonal brace 31 are bolted through the mating hole 310 and the connecting hole 321 respectively. This fixes the fixing diagonal brace 31 to the upright 1 via the sliding fastener 32. Due to the restriction of the position of the protrusion 320 by the fiber groove, the sliding fastener 32 can be prevented from rotating circumferentially along the upright 1, thereby preventing the position of the fixing diagonal brace 31 from deflecting due to force or vibration on the crossbar 2, ensuring the stability of the combined support frame connection structure.

[0042] Furthermore, the free reinforcing component 4 includes a free diagonal brace 41 and a butterfly fastener 42. The butterfly fastener 42 includes a first clip 421 and a second clip 422 that are rotatably connected. The inner side of the first clip 421 has a protrusion 320 that mates with the limiting groove 10. The first clip 421 can be directly replaced by a sliding fastener 32, and the second clip 422 is rotatably connected to the sliding fastener 32 using the connecting hole 321 on the sliding fastener 32. The combination of the butterfly fastener 42 and the free diagonal brace 41 allows the free diagonal brace 41 to have a flexible arrangement angle, thus serving as an auxiliary diagonal brace to disperse the force on the load-bearing parts and achieving a reinforcing effect on the entire combined support frame connection structure.

[0043] Furthermore, the fixed tie rod 31 includes a first tie rod 311 and a second tie rod 312 connected as a single unit. The first tie rod 311 and the second tie rod 312 can be connected in several ways, allowing the length of the fixed tie rod 31 to be changed.

[0044] Method 1:

[0045] like Figure 5 As shown, the first diagonal tie rod 311 and the second diagonal tie rod 312 are inserted and connected. Multiple equally spaced fixing holes 313 are formed on the first diagonal tie rod 311 and the second diagonal tie rod 312. The first diagonal tie rod 311 and the second diagonal tie rod 312 can be fixed by inserting fixing bolts 314 into the fixing holes 313. When it is necessary to change the length of the fixed diagonal tie rod 31, the fixing bolts 314 can be removed, the length of the first diagonal tie rod 311 extending into the second diagonal tie rod 312 can be changed, and the fixing holes 313 on the first diagonal tie rod 311 and the second diagonal tie rod 312 can be aligned. Then, the fixing bolts 314 can be inserted.

[0046] Method 2

[0047] like Figure 6 As shown, the first diagonal tie rod 311 and the second diagonal tie rod 312 are connected by a sleeve 315. The connecting ends of the first diagonal tie rod 311 and the second diagonal tie rod 312 are formed with external threads, and the inner side of the sleeve 315 is formed with internal threads that mesh with the external threads. When it is necessary to change the length of the fixed diagonal tie rod 31, simply rotate the first diagonal tie rod 311 or the second diagonal tie rod 312 to change the length of the first diagonal tie rod 311 or the second diagonal tie rod 312 extending into the sleeve 315.

[0048] Method 3

[0049] like Figure 7 As shown, the first diagonal tie rod 311 has an axially extending expansion groove 316, and the outer surface of the second diagonal tie rod 312 has an expansion protrusion 317 that mates with the expansion groove 316. When it is necessary to change the length of the fixed diagonal tie rod 31, only the length of the second diagonal tie rod 312 extending into the first diagonal tie rod 311 needs to be changed. Furthermore, to facilitate the fixing of the relative positions of the first diagonal tie rod 311 and the second diagonal tie rod 312, the following can be used: Figure 8 As shown, multiple locking slots are provided on the expansion slot 316. When in use, the first diagonal tie rod 311 or the second diagonal tie rod 312 can be rotated to allow the expansion protrusion 317 to enter the locking slot.

[0050] Furthermore, in order to prevent the sliding fastener 32 or the butterfly fastener 42 from sliding downwards, anti-slip textures are formed on the inner surfaces of the sliding fastener 32 and the first clip 421.

[0051] Furthermore, the upright 1 has a plurality of equally spaced radially penetrating mounting holes 11, which can be used to connect the connecting holes 321 and the mating holes 310. Bolts are used to pass through the connecting holes 321, the mating holes 310 and the mounting holes 11 to connect the fixed diagonal brace 31 and the sliding fastener 32 to the upright 1, thereby enhancing the stability of the connection.

[0052] Furthermore, such as Figure 9 As shown, a fixed connection area 101 is formed between the sliding fastener 32 and the limiting groove 10. The end of the crossbar 2 has a pin head 21 that extends into the fixed connection area 101, so that the vertical pole 1 and the crossbar 2 can be quickly connected by the cooperation of the pin head 21 and the sliding fastener 32.
