Description

Technical Field

[0001] The invention relates to the technical field of exhibition wall construction, and in particular to a quick-connect keel frame for exhibition wall construction. Background Art

[0002] Exhibition walls generally include a keel frame and exhibition panels. The keel frame is used to build the overall supporting structure of the exhibition wall to match or fit with the wall of the construction environment, and the exhibition panels are arranged on the surface of the completed keel frame.

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

[0004] Existing keel frames are generally constructed using metal parts of different shapes, including a number of beams, columns, support rods, etc., and the mutual connection of the above-mentioned components is generally carried out by welding or bolt connection supplemented by welding. Not only is the overall assembly efficiency not ideal, but the welds need to be destroyed during disassembly, which affects the recycling of the components, especially the rectangular frame structure formed by the beams and columns. When building the keel frame, it can provide a stable structure and a large frame area, which is convenient for quickly building the keel frame. However, during the construction process, the adjacent columns of the rectangular frame need to be welded and fixed, which is more inconvenient during disassembly. During transportation, it also occupies a large area, is inconvenient to stack, and cannot be disassembled. The rectangular frame can only be broken into beam sections and column sections and then stacked and transported, resulting in it being unable to be reused. Summary of the invention

DETAILED DESCRIPTION

[0045] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0046] Please refer to Figures 1 to 27 The embodiment of the present invention provides a quick-connect keel frame for exhibition wall construction, comprising: a plurality of cross beams 1 and a plurality of columns 2; a second plurality of square-head connectors 10, wherein the square-head connector 10 is provided with two pin beams 11 protruding therefrom, the two pin beams 11 being arranged vertically and coplanarly, the square-head connector 10 being provided with a latch 12 and a pin tube 13 arranged in parallel, the latch 12 being arranged parallel to and in the opposite direction to any one of the pin beams 11, the latch 12 and the pin tube 13 being arranged symmetrically about the median plane of the square-head connector 10; a third plurality of A plurality of adapter square heads 20, the side walls of which are provided with a plurality of adapter sockets 21; the pin beam 11 is used to be inserted into the end of the cross beam 1 or the column 2, so that a pair of the cross beams 1 and a pair of the columns 2 are vertically and coplanarly connected to form a rectangular frame; the latch 12 can be plugged into the pin tube 13 to connect the two square head connectors 10, so that the two rectangular frames are connected; the latch 12 can be plugged into the adapter socket 21, so that the two rectangular frames are connected through the two adapter square heads 20.

[0047] The quick-connect keel frame for exhibition wall construction provided in this embodiment provides basic construction conditions by setting up multiple crossbeams 1 and columns 2. On this basis, multiple square-head connectors 10 are set, and two pin beams 11 that are perpendicular to the same plane are set thereon. The two pin beams 11 are respectively plugged into the ends of a crossbeam 1 and a column 2, so that the crossbeam 1 and the column 2 are in a vertical and coplanar state. Therefore, a pair of crossbeams 1 and a pair of columns 2 can be spliced ​​into a rectangular frame through four square-head connectors 10, which is convenient for loading and unloading, and can be recycled by disassembly. On this basis, a latch 12 and a pin tube 13 are set parallel and symmetrically to the square-head connector 10, and the latch 12 is set parallel and opposite to a pin beam 11, so that the latch 12 of one square-head connector 10 can be inserted into the pin tube 13 of another square-head connector 10, and at the same time, the latch 12 of the second square-head connector 10 will also be inserted into the pin tube 13 of the first square-head connector 10. Thereby, the two square head connectors 10 are connected as one. Since the square head connector 10 is located at the corner of the rectangular frame, the columns 2 of the two rectangular frames can be aligned through the above connection method, and the ends of the two columns 2 are connected as one through the two pairs of square head connectors 10 The latches 12 and the pin tubes 13 are connected as one, so that the two rectangular frames are connected, which is convenient for loading and unloading, and can be recycled by disassembly; on this basis, by setting a plurality of adapter square heads 20, and setting a plurality of adapter sockets 21 on its side walls, when it is necessary to adjust the connection angle of the two rectangular frames, the transition between the two can be made through the adapter square head 20, so that the latches 12 of the two rectangular frames are respectively inserted into the adapter square head 20, and the angle between the two rectangular frames can be adjusted according to the angle between the different connecting surfaces of the adapter square head 20; through the mutual cooperation of the above-mentioned features, the quick-connect keel frame used for exhibition wall construction can effectively solve the problem that the existing keel frame is inconvenient to load and unload, and cannot be recycled.

[0048] Please refer to Figures 4 to 8 In order to further explain the connection structure of the latch 12 and the pin tube 13, the latch 12 is rotatably connected to the square head connector 10; a locking key 121 is convexly provided on the outer end side wall of the latch 12; a locking wrench 122 is convexly provided on the inner end side wall of the latch 12; a slot 131 matching the locking key 121 is formed on the side wall of the pin tube 13, the outer end of the slot 131 passes through the pin tube 13, and a locking slot 132 matching the locking key 121 is formed on the inner end slot wall; when the locking key 121 of one square head connector 10 is located in the locking slot 132 of another square head connector 10, the two square head connectors 10 abut against each other.

[0049] With the above settings, by using the locking key 121, the outer end of the bolt 12 is formed into a key shape, and by using the locking wrench 122, the bolt 12 can be manually rotated. On this basis, in cooperation with the slot 131 and the locking groove 132, the locking wrench 122 drives the bolt 12 to rotate until the locking key 121 is aligned with the slot 131, and then the bolt 12 is inserted into the pin tube 21. When the bolt 12 is inserted to the bottom of the pin tube 21, the locking wrench 122 drives the bolt 12 to rotate, so that the locking key 121 is screwed into the locking groove 132, and the locking of the bolt 12 and the pin tube 21 can be achieved.

[0050] It should be noted that the bolt 12 and the adapter jack 21 can be connected only by an axial plugging method, or the adapter jack 21 can also be designed with the same structure as the pin tube 13 (such as Fig. 9 ), and the locking is achieved by the insertion and screwing method.

[0051] In order to retract the bolt 12 when it is not required to be connected, and control its extension when it is required to be connected, the bolt 12 is slidably connected to the square head connector 10 along the axial direction; the square head connector 10 is provided with a U-shaped wrench groove 14, and the locking wrench 122 is slidably matched with the wrench groove 14. The wrench groove 14 includes an inner position groove 141, a push-pull groove 142 and an outer position groove 143 which are connected in sequence; when the locking wrench 122 is located in the inner position groove 141, the bolt 12 retracts into the square head connector 10; when the locking wrench 122 slides along the push-pull groove 142, the bolt 12 extends out of the square head connector 10, and the locking key 121 is aligned with the slot 131; when the locking wrench 122 is located in the outer position groove 143, the bolt 12 extends to the longest state, and the locking key 121 is aligned with the locking groove 132.

[0052] With the above settings, when the bolt 12 does not need to extend, it is only necessary to control the locking wrench 122 to drive the bolt 12 to rotate until the locking key 121 is aligned with the push-pull groove 142, and then control the locking wrench 122 to drive the bolt 12 to pull back along the push-pull groove 142, and then control the locking wrench 122 to drive the bolt 12 to rotate, so that the locking key 121 is screwed into the inner position groove 141; similarly, when the bolt 12 needs to extend, it is only necessary to control the locking wrench 122 to drive the bolt 12 to extend, and then drive the locking key 121 to be screwed into the outer position groove 143.

[0053] In order to realize the self-expulsion of the latch pin 12 and enable the locking wrench 122 to be limited and engaged in the inner groove 141 and the outer groove 143 to prevent the locking wrench 122 from slipping off, a spring 123 is coaxially provided at the inner end of the latch pin 12. When the spring 123 is in a natural state, the latch pin 12 can be extended to its longest state; a limiting protrusion 144 is convexly provided on the groove wall at one end where the inner groove 141 and / or the outer groove 143 are connected to the push-pull groove 142.

[0054] Please refer to Fig.19 and Fig. 20 In order to provide different transfer conditions, all of the transfer square heads 20 include a plurality of four-way square heads 201 and a plurality of corner square heads 202; the four-way square head 201 is in a cubic shape, and all of the transfer sockets 21 are evenly opened on the four side walls of the four-way square head 201; the corner square head 202 is provided with two connecting surfaces, and the angle between the two connecting surfaces is 5°-135°, and all of the transfer sockets 21 are evenly opened on the two connecting surfaces of the corner square head 202.

[0055] It should be noted that during the installation process, multiple four-way square heads 201 and multiple corner square heads 202 with different connection surface angles can be used in combination according to actual needs to assemble different angles and sizes to achieve the purpose of diversified angles and flexible shapes.

[0056] Please refer to Figure 21 to Figure 29 In order to further improve the connection performance between the columns 2, so as to avoid the pin beam 11 from being disengaged from the cross beam 1, or to avoid the pin 12 from being disengaged from the pin tube 13 or the adapter socket 21, the above-mentioned quick-connect keel frame for building the exhibition wall also includes a plurality of column clips 30, and the two opposite sides of the column clip 30 are respectively provided with a plurality of ears 31, and the ears 31 include mutually connected hanging parts 311 and connecting parts 312, and the connecting parts 312 are connected to the column clip 30, and the hanging parts 311 are spaced apart from the column clip 30 to form a card slot 32 between the hanging parts 311 and the column clip 30; a plurality of elastic The elastic positioning member 33 corresponds to the ear 31 one by one, and the elastic positioning member 33 is arranged at the corresponding hanging clamp part 311. When the elastic positioning member 33 is in a natural state, the elastic positioning member 33 fills the clamping slot 32 along the slot width direction; the column 2 is provided with a plurality of hanging plates 3 along the length direction, and the hanging plates 3 are provided with a plurality of hanging holes 4 along the thickness direction, and the thickness of the hanging plates 3 is ≤ the slot width of the clamping slot 32; the column clamping member 30 can be hung and clamped with the hanging hole 4 through the ear 31, so that the two columns 2 can be connected in parallel through the plurality of column clamping members 30.

[0057] By setting a plurality of column clamping members 30, the side walls of adjacent columns 2 are detachably connected by using them, thereby sharing the connection tasks undertaken by the pin beam 11 and the latch 12. Specifically, by setting a plurality of clamping ears 31 on the column clamping member 30, a plurality of hooks protruding from the outer wall of the column clamping member 30 are formed, and a hanging plate 3 is set on the column 2, and a hanging hole 4 is opened on the hanging plate 3. When in use, it is only necessary to hang and connect a plurality of the column clamping members 30 with the hanging holes 4 of the two columns 2 through the clamping ears 31 on both sides, so that the two columns 2 can be quickly connected. When disassembling, it is only necessary to reverse the operation. On this basis, by setting the hanging ears 31 including the hanging clamping part 311 And the connecting part 312, while the connecting part 312 is used to support the connection between the hanging clamp part 311 and the column clamp part 30, a slot 32 with a stable structure and controllable slot width is formed between the hanging clamp part 311 and the column clamp part 30 to implement the hanging and clamping connection; on this basis, by setting an elastic positioning part 33, when the hole edge of the hanging hole 4 (or the hanging plate 3 where the hanging hole 4 is located) is gradually inserted into the slot 32, it will gradually squeeze the elastic positioning part 33, so that the elastic positioning part 33 elastically retreats, and conversely, the elastic positioning part 33 reversely squeezes the hole edge of the hanging hole 4 (or the hanging plate 3 where the hanging hole 4 is located) to clamp it, thereby implementing the connection positioning and improving the stability of the connection structure.

[0058] In order to facilitate the construction of the keel frame and adapt to the external environment, and to improve the structural performance after the clamping, and to avoid the situation where the clamping directions of the two sides are the same, resulting in the force on one side causing the other side to loosen and withdraw from the clamp, the column clamp 30 is in a linear strip shape, and all the ears 31 are respectively arranged on the two opposite side walls of the column clamp 30, and the depth direction of the slot 32 is parallel to the length direction of the column clamp 30; the opening direction of the slot 32 of each column of the ears 31 is the same, and the opening directions of the slots 32 of the two columns of the ears 31 are opposite.

[0059] With the above arrangement, when force is applied on one side, such as downward force, the direction of the force applied to the ear 31 on the other side is also downward, that is, opposite to the direction of the slot 32, so it will not be unfastened but will be further clamped.

[0060] In order to further explain the specific structure of the hanging card part 311, the hanging card part 311 is in the shape of a linear strip, and the length direction of the hanging card part 311 is arranged in parallel with the length direction of the column clamp 30, so that the card slot 32 is a slot of equal width; one end of the hanging card part 311 in the length direction is connected to the connecting part 312, so that the bottom of the slot 32 is closed; the side wall of the hanging card part 311 away from the connecting part 312 is set as an arc surface, so that the slot width of the slot 32 gradually decreases with the depth.

[0061] By setting the hanging clamp portion to be a linear strip, the card slot 32 is made into a uniform width slot, which facilitates the hanging of the hanging plate 3 with uniform thickness. By setting the side wall of the free end of the hanging clamp portion 311 to be an arc surface, the slot width of the card slot 32 gradually decreases with the depth, which further facilitates guiding the hanging plate 3 to be inserted into the card slot 32.
