Description

Technical Field

[0001] This utility model relates to the technical field of exhibition wall keel connectors, specifically to a square-headed connecting mechanism and a right-angled frame. Background Technology

[0002] Exhibition walls typically consist of a frame and display panels. The frame is used to build the overall support structure of the exhibition wall to match or fit the walls of the environment. The display panels are placed on the surface of the completed frame.

[0003] To facilitate assembly, disassembly, and transportation, the keel frame generally includes several interconnected components. After being transported to the construction environment, it is then assembled according to the specific conditions of the construction environment. The efficiency of keel frame assembly directly determines the construction efficiency of the entire exhibition wall. Similarly, the efficiency of keel frame disassembly directly determines the efficiency of subsequent replacement and transportation.

[0004] Existing keel frames are generally constructed using metal components of different shapes, including several beams, columns, and support rods. The interconnection of these components is generally achieved through welding or bolting, supplemented by welding. This not only results in unsatisfactory overall assembly efficiency but also requires damage to the welded joints during disassembly, thus affecting the recycling of components. In particular, the rectangular frame structure formed by the beams and columns provides a stable and large frame area for quick keel frame construction. However, it also occupies a large area during transportation, making it inconvenient to stack and cannot be disassembled. The rectangular frame can only be broken into beam and column sections before stacking and transportation, making it unusable. Utility Model Content

Detailed Implementation

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this utility model are only used to explain this utility model and are not intended to limit this utility model.

[0032] Example

[0033] Please refer to Figures 1 to 12This embodiment provides a square-headed connection mechanism, including a base 10, on which two pin beams 11 are protruding. The two pin beams 11 are perpendicular and coplanar, and are respectively used to insert into the ends of a crossbeam and a column, so that the crossbeam and column are connected perpendicularly and coplanarly. The second part includes parallel pins 20 and pin tubes 21, with the pins 20 parallel to and opposite to any one of the pin beams 11, and the pins 20 and pin tubes 21 symmetrically arranged with respect to the mid-plane of the base 10. The third part includes a first locking mechanism, which locks the pin beams 11 to the crossbeam or column, so that the base 10 is spliced ​​with the crossbeam or column. The fourth part includes a second locking mechanism, which locks the pins 20 to the pin tubes 21, so that the two bases 10 are spliced.

[0034] The square-head connecting mechanism provided in this embodiment, by setting a base 10 and providing two protruding pin beams 11 on the base 10, makes the two pin beams 11 perpendicular and coplanar. The two pin beams 11 are respectively inserted into the crossbeam and the column, thereby connecting the crossbeam and the column perpendicularly and coplanarly into one unit. Based on this, by setting four bases 10, a pair of crossbeams and a pair of columns can be connected to form a rectangular frame. By setting a first locking mechanism, the crossbeam or column is locked to the inserted pin beams 11, thus ensuring the structural stability of the rectangular frame. This structure is not only quick to assemble and disassemble, but also does not require damage to the crossbeams or columns during disassembly, and can be recycled. Furthermore... By providing pins 20 and pin tubes 21 on the base 10 and symmetrically arranging them, when the pin 20 of one base 10 is inserted into the pin tube 21 of the other base 10, the pin 20 of the other base 10 is also simultaneously inserted into the pin tube 21 of that base 10; thus, the two bases 10 can be connected to each other, and the rectangular frames connected to the two bases 10 can be connected to each other. On this basis, by providing a second locking mechanism, the connection stability of the two connected bases 10 is ensured. Through the cooperation of the above features, the square-head connection mechanism can solve the problems of inconvenient loading and unloading and non-recyclability while ensuring connection performance.

[0035] To further explain the specific structure of the second locking mechanism, the second locking mechanism includes a locking key 30 and a locking wrench 31; the pin 20 is rotatably connected to the base 10; the locking key 30 is located on the outer end side wall of the pin 20; the locking wrench 31 is located on the inner end side wall of the pin 20; the side wall of the pin tube 21 has a slot 211 that matches the locking key 30, and the inner end groove wall of the slot 211 has a locking groove 212 that matches the locking key 30; when the locking key 30 of one base 10 is located in the locking groove 212 of another base 10, the two bases 10 abut against each other.

[0036] With the above setup, the locking key 30 is used to make the outer end of the pin 20 form a key shape. The locking wrench 31 is used to make the pin 20 rotate manually. Based on this, in conjunction with the slot 211 and the locking groove 212, the locking wrench 31 is used to drive the pin 20 to rotate until the locking key 30 is aligned with the slot 211. Then, the pin 20 is inserted into the pin tube 21. When the pin 20 is inserted into the bottom of the pin tube 21, the locking wrench 31 is used to drive the pin 20 to rotate, so that the locking key 30 is screwed into the locking groove 212, thus achieving the locking of the pin 20 and the pin tube 21.

[0037] To retract the pin 20 when it is not needed for connection and extend it when it is needed for connection, the pin 20 is slidably connected to the base 10 along the axial direction. The base 10 has a C-shaped wrench groove 12, and the locking wrench 31 is slidably engaged with the wrench groove 12. The wrench groove 12 includes an inner groove 121, a push-pull groove 122, and an outer groove 123 connected in sequence. When the locking wrench 31 is located in the inner groove 121, the pin 20 is retracted into the base 10. When the locking wrench 31 slides along the push-pull groove 122, the pin 20 extends out of the base 10, and the locking key 30 is aligned with the slot 211. When the locking wrench 31 is located in the outer groove 123, the pin 20 extends to its longest position, and the locking key 30 is aligned with the locking groove 212.

[0038] With the above settings, when the pin 20 does not need to extend, simply control the locking wrench 31 to rotate the pin 20 until the locking key 30 is aligned with the push-pull groove 122, then control the locking wrench 31 to pull the pin 20 back along the push-pull groove 122, and then control the locking wrench 31 to rotate the pin 20 so that the locking key 30 is screwed into the inner groove 121; similarly, when the pin 20 needs to extend, simply control the locking wrench 31 to screw the locking key 30 into the outer groove 123.

[0039] In order to enable the self-extraction of the pin 20 and to allow the locking wrench 31 to be locked in the inner slot 121 and the outer slot 123 to prevent the locking wrench 31 from slipping out, a spring 32 is coaxially provided at the inner end of the pin 20. When the spring 32 is in its natural state, the pin 20 can extend to its longest state. The inner slot 121 and the outer slot 123 are provided with limiting protrusions 124 on the groove wall at the end connected to the push-pull groove 122.

[0040] To further explain the specific structure of the first locking mechanism, the pin beam 11 is hollow, forming a cavity 111 inside; the first locking mechanism includes an elastic element 40 and a protruding post 41, the protruding post 41 being slidably connected to the side wall of the pin beam 11 perpendicularly, the elastic element 40 being embedded in the cavity 111, and the elastic element 40 being connected to the inner end of the protruding post 41; when the elastic element 40 is in its natural state, the outer end of the protruding post 41 extends out from the side wall of the pin beam 11.

[0041] With the above configuration, the elastic element 40 allows the protruding post 41 to be pressed in or extended. In use, it is only necessary to open a through hole matching the protruding post 41 on the side wall of the beam or column. In use, the pin beam 11 is inserted into the end of the beam or column, and the protruding post 41 is pressed in during the process. Then, the insertion is continued until the protruding post 41 pops out from the corresponding through hole, thus realizing the detachable connection and fixation between the pin beam 11 and the beam or column.

[0042] To further explain the specific structure of the elastic element 40, the elastic element 40 is in the shape of a bent sheet. One side of the fold line of the elastic element 40 is connected to the inner end of the protrusion 41, and the other side is connected to the cavity wall of the cavity 111.

[0043] To provide multiple connection angles, the aforementioned square head connection mechanism also includes several adapter square heads. The bottom of each adapter square head is provided with a pin 50, which is used to insert into the end of the column. The side wall of each adapter square head has multiple adapter holes 51, and the pin 20 can be inserted into the adapter holes 51.

[0044] With the above settings, when the two rectangular frames are connected as rectangular frames, the edges of the two rectangular frames need to be connected at a specific angle. This can be achieved by using adapter square heads between the two. The two adapter square heads are inserted into the two ends of a column through pins 50, and then connected to the pins 20 of the base 10 of the two rectangular frames through the adapter insertion holes 51 on the side walls of the two adapter square heads.

[0045] To provide different connection conditions, all the adapter square heads include several four-way square heads 52 and several corner square heads 53; the four-way square heads 52 are cubic in shape, and all the adapter sockets 51 are evenly opened on the four side walls of the four-way square heads 52; the corner square heads 53 are provided with two connecting surfaces, and the included angle between the two connecting surfaces is 5°-135°.

[0046] It should be noted that during installation, multiple four-way square heads 52 and multiple corner square heads 53 with different connecting surface angles can be used in combination according to actual needs to assemble different angles and sizes, so as to achieve the purpose of diverse angles and flexible shapes.

[0047] To facilitate the subsequent attachment of curtains and other outer coverings to the keel frame, multiple fabric mounting grooves 54 are provided on the surfaces of the substrate 10 and the adapter square head.

[0048] Please Figures 1 to 12 Continue to refer to Figure 13 This embodiment also provides a right-angle frame, including: multiple horizontal beams 1 and multiple vertical columns 2, the ends of the horizontal beams 1 and the vertical columns 2 are provided with slots; the second includes multiple square-head connecting mechanisms of any of the above, the two pin beams 11 of each base 10 are respectively inserted into one horizontal beam 1 and one vertical column 2, so that the two horizontal beams 1 and the two vertical columns 2 form a rectangular frame.
