Description

Technical Field

[0001] The present application relates to the technical field of exhibition profiles, and in particular to a connection assembly and a profile frame of a profile structure. Background Art

[0002] In the application of profile exhibition construction, bolt connection is currently the most commonly used connection method between profile structures and their connecting parts, or between profile structures. However, although traditional bolt connection technology occupies a dominant position in the connection of profile structures and is widely used in various scenarios, its limitations are gradually becoming apparent in the pursuit of more efficient, faster and more convenient modern exhibition construction needs.

[0003] Specifically, traditional bolt connections require the combined use of multiple accessories, such as bolts, nuts, and washers. The large number of these accessories not only increases the difficulty of storage and management, but also makes them easily lost during transportation and use, thus affecting the smooth progress of the entire construction work. In addition, bolt connections require the use of tools for tightening, which is highly complex to operate and prolongs the installation time. This is particularly inconvenient in situations that require quick response and instant construction. Especially for high-altitude displays or environments with limited installation space, carrying and using bolt tightening tools becomes an additional burden, and may even make it impossible to achieve an effective connection.

[0004] Therefore, this application is specially filed. Utility Model Content

[0039] like Figures 1 to 3 As shown, a connection assembly of a profile structure provided in an embodiment of the present application includes a bolt connector 10 and a nut connector;

[0040] The bolt connector 10 includes a first screwing structure 11, a bolt body 12 and a first fixing structure 13. One end of the bolt body 12 is provided with a thread c, and the other end is detachably connected to the first screwing structure 11 through the first fixing structure 13; the nut connector 20 includes a second screwing structure 21, a nut body 22 and a second fixing structure 23. The second fixing structure 23 is detachably connected to the second screwing structure 21, and the nut body 22 is arranged inside the second fixing structure 23. The second screwing structure 21, the nut body 22 and the second fixing structure 23 form a through connection hole b after combination; the bolt body 12 extends into the connection hole b through one end provided with a thread c and is threadedly connected to the nut body 22.

[0041] Specifically, the bolt connector 10 adopts a detachable connection structure, that is, one end of the bolt body 12 is connected to the first screwing structure 11 through the first fixed structure 13. This design makes the bolt connector 10 more flexible and convenient during assembly and disassembly, and the operation can be completed without the use of complex tools. At the same time, the first screwing structure 11 adopts a design that is easy to rotate manually, and the nut connector 20 also adopts a detachable design. The connection between the second screwing structure 21 and the second fixed structure 23 allows the user to easily assemble or disassemble the nut connector as needed. This design not only reduces the risk of loss of accessories, but also makes the nut connector 20 more compact and easy to manage during transportation and storage. In addition, the nut body 22 is arranged inside the second fixed structure 23, and together with the second screwing structure 21 forms a through connection hole b. This structure ensures that the bolt body 12 can be smoothly inserted and formed with it to form a threaded connection, thereby achieving a stable connection of the profile structure. In actual application, when two profile structures need to be connected, the user only needs to insert the bolt body 12 of the bolt connector 10 into the connection hole b of the nut connector 20 through the end provided with the thread c, and rotate the first screwing structure 11 or the second screwing structure 21 to drive the bolt body 12 to be threadedly connected with the nut body 22. No additional tools are required during the entire process, and the connection is firm and reliable, which effectively solves the problems of cumbersome installation and unstable connection in the existing technology.

[0042] In summary, the profile structure connection assembly 100 provided in the embodiment of the present application achieves a fast, convenient and stable connection of the profile structure by optimizing the structural design of the bolt connector 10 and the nut connector 20, meeting the needs of the modern construction and exhibition industries for efficient, safe and reliable connection technology.

[0043] In the solution of the present application, a relatively protruding first connecting portion 111 is provided at one end of the first screwing structure 11; the first fixing structure 13 includes a first sleeve 131 and a first screw plug 132, and the first sleeve 131 is provided with a first mounting hole a1 passing through it; it is sleeved to the first connecting portion 111 through the first mounting hole a1, and the bolt body 12 is clamped by the first screw plug 132.

[0044] Specifically, a relatively protruding first connecting portion 111 is provided at one end of the first screwing structure 11 to facilitate precise docking with the first fixing structure 13. The first fixing structure 13 is composed of a first sleeve 131 and a first screw plug 132, which achieve the fixation and connection of the bolt body 12. A first mounting hole a1 is provided through the first sleeve 131. The size and shape of this hole match the first connecting portion 111, allowing the first sleeve 131 to be smoothly sleeved on the first connecting portion 111. This sleeve-type installation method is not only simple and quick, but also ensures a tight connection between the first screwing structure 11 and the first fixing structure 13.

[0045] The first screw plug 132 secures the bolt body 12 within the first sleeve 131, preventing the bolt body 12 from loosening or falling out. Furthermore, the first screw plug 132 is designed for ease of disassembly, allowing the user to easily unscrew or remove it when needed, allowing for disassembly and reassembly of the bolt connector 10.

[0046] In the present application, the bolt body 12 includes a rod portion t1 and a nut portion t2, and a thread c is arranged at one end of the rod portion t1 away from the nut portion t2; the nut portion t2 can be placed in the first mounting hole a1 and one side thereof is in contact with the first connecting portion 111, and the first screw plug 132 can be put onto the rod portion t1 and at the same time extend into the first mounting hole a1 to be in contact with the other side of the nut portion t2, thereby locking the bolt body 12.

[0047] It can be understood that the thread c is provided at the end of the rod portion t1 away from the nut portion t2, and is used to threadably connect with the nut body 22 of the nut connector 20 to achieve the fastening of the profile structure. The design of the nut portion t2 fully considers the cooperation with the first fixing structure 13. When the bolt body 12 is inserted into the first sleeve 131, the nut portion t2 can be smoothly placed into the first mounting hole a1, and one side of it abuts against the first connecting portion 111. This abutment not only helps to position the bolt body 12, but also provides a certain preload force during the connection process. To more firmly fix the bolt body 12, the first screw plug 132 is designed to pass through the rod portion t1 and extend into the first mounting hole a1. During the insertion of the first screw plug 132, it abuts against the other side of the nut portion t2. Due to the clamping of the first screw plug 132 and the first mounting hole a1, the bolt body 12 is fixed.

[0048] Correspondingly, a relatively protruding second connecting portion 211 is provided at one end of the second screwing structure 21, and a first through hole b1 is provided at the second screwing structure 21; the second fixing structure 23 includes a second sleeve 231 and a second screw plug 232; the second sleeve 231 is provided with a second through hole b2, and the nut body 22 is provided with a third through hole b3; wherein, the first through hole b1, the second through hole b2 and the third through hole b3 are coaxially arranged, and when the second screwing structure 21, the nut body 22 and the second fixing structure 23 are combined, the first through hole b1, the second through hole b2 and the third through hole b3 are connected to each other to form a connecting hole b.

[0049] A relatively protruding second connecting portion 211 is provided at one end of the second screwing structure 21 to cooperate with the second sleeve 231, so that the second screwing structure 21 can smoothly drive the nut body 22 to be threadedly connected when rotating, thereby improving the efficiency of the connection. The second fixing structure 23 is composed of the second sleeve 231 and the second screw plug 232, which together provide a storage space for the nut body 22. At the same time, the second through hole b2 provided on the second sleeve 231 and the third through hole b3 on the nut body 22 are coaxially arranged, ensuring that when the three are combined, they can form a continuous, through-hole connection b. This connection hole b is the channel through which the bolt body 12 extends and is threadedly connected to the nut body 22. At the same time, due to the coaxial arrangement, the bolt body 12 can maintain linear motion when extending into the connection hole b, reducing friction and wear caused by deflection.

[0050] Furthermore, the second sleeve 231 can be sleeved onto the second connecting portion 211 through the second through hole b2, and the nut body 22 can be placed in the second through hole b2, with one side abutting against the second connecting portion 211; the second screw plug 232 extends into the second through hole b2 and abuts against the other side of the nut body 22 to lock the nut body 22.

[0051] The second sleeve 231 is mounted on the second connecting portion 211 via the second through hole b2. This mounting method is not only simple and quick, but also ensures a tight connection between the second sleeve 231 and the second screwing structure 21. Furthermore, since the second through hole b2 extends through the second sleeve 231, it provides space for the nut body 22 to be placed. The nut body 22 can now be placed within the second through hole b2, with one surface abutting against the second connecting portion 211. This abutment not only helps position the nut body 22 but also provides a certain preload during the connection process, ensuring a secure connection.

[0052] In order to more firmly lock the nut body 22, the second screw plug 232 is designed to be able to extend into the residual space in the second through hole b2, and to abut against the other side of the nut body 22, so as to fix the nut body 22 by clamping, thereby preventing it from moving or loosening during the connection process, and avoiding displacement or wear during the threaded connection; at the same time, the design of the second screw plug 232 also takes into account the convenience of disassembly, and the user can easily pull it out when needed to realize the disassembly and reassembly of the nut connector 20.

[0053] The inner wall hole shapes of the first through hole b1, the second through hole b2, and the third through hole b3, as well as the second connecting portion 211, are all configured as mutually matching polygons; and / or the inner wall hole shape of the first mounting hole a1, the first connecting portion 111, and the nut portion t2 are all configured as mutually matching polygons; this polygonal design can be a quadrilateral, hexagon, octagon, etc., and the specific shape can be selected according to actual needs and connection strength. The polygonal design allows the various components to fit tightly together during connection, reducing gaps caused by rotation or misalignment, thereby improving the tightness and stability of the connection. At the same time, it can also effectively prevent the bolt body 12 from rotating or loosening during the connection process. The polygonal design makes the connection more stable and reliable through full rotational freedom.

[0054] The first sleeve 131 and the second sleeve 231 have the same structure; the first screw plug 132 and the second screw plug 232 have the same structure. This means that the same molds, processes, and equipment can be used during the production process, thereby simplifying the production process and improving production efficiency. Since the first sleeve 131 and the second sleeve 231, as well as the first screw plug 132 and the second screw plug 232 have the same structure, they can be interchangeable. This interchangeability allows only one or a few standardized parts to be stocked to meet various needs, while reducing the risk of loss and improving production efficiency.

[0055] The length of the rod t1 is greater than the depth of the connecting hole b so that it can penetrate the connecting hole b; that is, the bolt connector 10 and the nut connector 20 have a longer operating stroke; by adjusting the locking length of the bolt, the bolt connector 10 and the nut connector 20 can adapt to profile structures of various sizes, have a wide range of applications, and can meet different connection requirements.

[0056] The outer periphery of the first screwing structure 11 and the second screwing structure 21 is at least partially provided with a screwing thread c; the design of the screwing thread c allows the user to easily tighten or loosen the bolt connector 10 and the nut connector 20 by rotating the first screwing structure 11 or the second screwing structure 21, which can reduce hand fatigue and improve work efficiency.

[0057] The bolt body 12 and the nut body 22 may both be universal accessories, such as an M8 bolt and an M8 nut with a length of 9 to 11 cm.

[0058] The second aspect of the present application further provides a profile frame (not shown), comprising a plurality of profile structures (not shown) and a plurality of connection assemblies 100 as described above, wherein the plurality of profile structures are connected by the connection assemblies.

[0059] It can be understood that the profile structure can adopt a modular design, that is, the entire profile frame is constructed by combining multiple profile structures with connecting components 100, so that the construction of the frame becomes flexible and efficient, and the number and layout of components can be adjusted according to actual needs to meet different size and functional requirements.

[0060] The various technical features described above can be combined arbitrarily. Although not all possible combinations of these technical features are described, any combination of these technical features should be considered to be covered by this specification as long as such combination does not conflict.

[0061] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still adjust the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these adjustments or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
