[0060] While the rental display industry is developing rapidly, it does have some drawbacks, particularly regarding the installation and securing of the display cabinets. Rental display cabinets require frequent assembly and disassembly, and quick installation and disassembly are essential. To accommodate fast-paced event schedules, the rental display frames must be capable of rapid installation and disassembly.

[0061] Currently, most display screen connectors on the market are fixed using screws or multiple locking mechanisms, typically requiring multiple screws, which increases installation and disassembly time. Therefore, this application provides a connection structure that can be applied to the assembly of rental display screen cabinets, significantly reducing installation and disassembly time.

[0062] The first aspect of this application provides a connection structure, such as...Figures 1 to 5 As shown, the connecting structure comprises a connecting seat 10 and a locking assembly 20 arranged in the connecting seat 10;

[0063] The connecting seat 10 is used for positioning the external connecting piece, and the locking assembly 20 is used for locking cooperation with the external connecting piece.

[0064] Taking a rental screen as an example, when assembling the modular frame, the connecting seat 10 is used to position the connecting piece on the modular frame, so that the modular frame can be quickly moved to the preset assembly position, and then the locking assembly 20 is used for locking cooperation, so that the assembly efficiency can be effectively improved, and the time and manpower can be effectively saved.

[0065] In some embodiments, as shown, Figures 1 to 5 As shown, the connecting seat 10 is provided with a first connecting channel 100 and a second connecting channel 102 on both sides, and the first connecting channel 100 and the second connecting channel 102 are used for placing the external connecting piece;

[0066] The locking assembly 20 comprises a first locking piece 21, a second locking piece 22, and an elastic member 23 for moving the first locking piece 21 and the second locking piece 22 in a direction away from each other, the first locking piece 21 is locked with the external connecting piece in the first connecting channel 100, and the second locking piece 22 is locked with the external connecting piece in the second connecting channel 102.

[0067] The above connecting structure is designed ingeniously, and the external connecting piece is quickly and stably locked through the cooperation of the connecting seat 10 and the locking assembly 20. The first connecting channel 100 and the second connecting channel 102 provide a clear installation path for the external connecting piece, which can be quickly positioned to ensure accurate placement and locking. The first connecting channel 100 and the second connecting channel 102 are locked with the external connecting piece in the first connecting channel 100 and the second connecting channel 102, respectively, through the first locking piece 21 and the second locking piece 22. Combined with the action of the elastic member 23, the quick locking or unlocking operation can be realized, the time for manual adjustment is effectively reduced, the installation efficiency is improved, and it is especially suitable for scenes that need to be frequently disassembled, such as display screen box splicing, stage equipment assembly, etc. The connecting seat 10 integrates the locking assembly 20, and all functional components are hidden in the connecting seat 10, so that the overall structure is compact.

[0068] In application, the connecting structure is applied to the splicing of the display screen box, and the splicing between the plurality of modular frames is fixed through the connecting structure. The external connecting piece is usually arranged on the modular frame, which includes but is not limited to: locking pin, screw, fixed column, etc.

[0069] In the application, the elastic member 23 is a spring, two ends of the elastic member 23 are connected with the first locking sheet 21 and the second locking sheet 22 respectively, and the elastic member 23 has an elastic potential energy for moving the first locking sheet 21 and the second locking sheet 22 in a direction away from each other. In a specific embodiment, two groups of elastic members 23 are arranged, and the two groups of elastic members 23 are arranged at two ends of the first locking sheet 21 and the second locking sheet 22 on one side, so as to improve the locking degree of the first locking sheet 21 and the second locking sheet 22 to the external connecting member and improve the overall reliability.

[0070] It should be noted that the locking cooperation between the first locking sheet 21, the second locking sheet 22 and the external connecting member includes the following cases: when the external connecting member is a locking pin or a screw, and the head of the locking pin is larger than the middle part (similar to the shape of a screw), the first locking sheet 21 and the second locking sheet 22 are in clamping cooperation with the external connecting member, that is, the first locking sheet 21 and the second locking sheet 22 have potential energy for moving in opposite directions under the action of the elastic member 23, so as to tightly abut and clampingly fix the external connecting member, thereby realizing the locking cooperation. When the external connecting member is a fixed column (and the fixed column is in a whole cylindrical shape), the first locking sheet 21 and the second locking sheet 22 tightly abut the external connecting member under the action of the elastic member 23, thereby realizing the locking cooperation. In the preferred embodiment, the external connecting member is a screw or a bolt, and the head is larger than the tail, so as to limit the first locking sheet 21 and the second locking sheet 22 in the vertical direction, which is beneficial to improve the firmness of the locking assembly 20.

[0071] In some embodiments, as shown in Figure 3 and Figure 5 a first locking groove 210 is arranged on the first locking sheet 21, the first locking sheet 21 is locked with the external connecting member in the first connecting channel 100 through the first locking groove 210, and the shape of the first locking groove 210 is matched with the shape of the external connecting member. In other embodiments, a second locking groove 220 is arranged on the second locking sheet 22, the second locking sheet 22 is locked with the external connecting member in the second connecting channel 102 through the second locking groove 220, and the shape of the second locking groove 220 is matched with the shape of the external connecting member. By arranging the locking grooves matched with the shape of the external connecting member on the first locking sheet 21 and the second locking sheet 22, the first locking sheet and the second locking sheet will be more closely matched with the external connecting member, and the locking cooperation degree between them will be improved, thereby improving the connection accuracy and stability.

[0072] In application, the design of the first locking groove 210 and the second locking groove 220 can improve the locking accuracy. The shape of the first locking groove 210 and the second locking groove 220 is matched with the shape of the external connecting piece, which can realize accurate geometric matching. It ensures that the external connecting piece is firmly clamped into the locking groove, avoiding loosening or slipping. It is beneficial to enhance the connection stability, and the design of the locking groove increases the contact area between the locking piece and the external connecting piece, and at the same time forms a stronger constraint force through shape matching.

[0073] In application, by adjusting the shape of the first locking groove 210 and the second locking groove 220, external connecting pieces of different shapes (such as circular, square, polygon, etc.) can be matched. It improves the versatility of the connection structure and is suitable for various types of external connecting pieces. The shape matching design of the locking groove provides a clear insertion path for the external connecting piece, avoiding installation errors caused by misoperation. It simplifies the installation process and reduces the skill requirements for the operator. It improves the installation efficiency and reduces the possibility of rework.

[0074] In application, the shape matching of the locking groove and the external connecting piece forms a "bite" effect, increasing the escape resistance. Even if subjected to a larger pulling force or vibration, the external connecting piece is not easy to fall off. It improves the safety of the connection, especially in situations that require long-term stable connection. The design of the locking groove makes it more convenient to disassemble the external connecting piece, which can be completed by reversing the operation.

[0075] In some embodiments, as shown in Figure 3 and Figure 5 The first locking piece 21 is provided with a first guide groove 211, and the connecting seat 10 is provided with a first guide piece 24 matched with the first guide groove 211 to realize positioning and guiding of the first locking piece 21. In other embodiments, the second locking piece 22 is provided with a second guide groove 221, and the connecting seat 10 is provided with a second guide piece 25 matched with the second guide groove 221 to realize positioning and guiding of the second locking piece 22. Through the cooperation of the first guide groove 211 and the first guide piece 24, and the second guide groove 221 and the second guide piece 25, it ensures that the first locking piece 21 and the second locking piece 22 move along the predetermined path during movement. Prevent the locking piece from deviating or being stuck under the action of the elastic piece 23, ensure that the locking piece can accurately reach the locking position, and improve the reliability of the connection.

[0076] In the application, the guide is a guide positioning pin. The cooperation between the guide groove and the guide provides a clear positioning reference for the lock piece. It ensures that the lock piece is always in the correct position in the locked or unlocked state. The cooperation between the guide groove and the guide reduces the friction between the lock piece and other components, reduces the wear of the lock piece due to frequent movement, and prolongs the service life of the entire connection structure. The design of the guide groove and the guide makes the movement of the lock piece smoother and faster. When the external connecting piece is inserted, the lock piece can quickly complete the locking action. When unlocking is needed, the lock piece can quickly reset, improving the operation efficiency.

[0077] In some embodiments, as shown in Figure 3 The connection structure further comprises a first switch assembly 30 and a second switch assembly 40 for controlling the locking and unlocking of the first lock piece 21 and the second lock piece 22 with the external connecting piece, respectively, and the first switch assembly 30 and the second switch assembly 40 are installed on the connection seat 10. The first switch assembly 30 and the second switch assembly 40 can independently control the action of the first lock piece 21 and the second lock piece 22, respectively, and the user can control the locking or unlocking of one side according to the actual needs, without affecting the state of the other side, improving the operation flexibility of the connection structure, especially in the case of partial locking or unlocking.

[0078] In some embodiments, as shown in Figure 3 The first switch assembly 30 comprises:

[0079] A first knob 31 is rotatably installed on the side of the connection seat 10 away from the external connecting piece;

[0080] A first rotating eccentric wheel 32 is embedded on the first lock piece 21;

[0081] A first positioning member 33 is connected to one end of the first knob 31, and the other end of the first positioning member 33 is inserted into the eccentric hole on the first rotating eccentric wheel 32;

[0082] By rotating the first knob 31, the rotation is converted into moving the first lock piece 21 away from or close to the second lock piece 22 in the direction by the first rotating eccentric wheel 32.

[0083] In other embodiments, as shown in Figure 3 The second switch assembly 40 comprises:

[0084] A second knob 41 is rotatably installed on the side of the connection seat 10 away from the external connecting piece;

[0085] A second rotating eccentric wheel 42 is embedded on the second lock piece 22;

[0086] A second positioning member 43 is connected to one end of the second knob 41, and the other end of the second positioning member 43 is inserted into the eccentric hole on the second rotating eccentric wheel 42;

[0087] By rotating the second knob 41, the rotation is converted into moving the second locking piece 22 away from or close to the first locking piece 21 through the second rotating eccentric wheel 42.

[0088] The switch assembly utilizes the cooperation of the knob, rotating eccentric wheel and positioning piece. The rotation of the knob is transmitted to the rotating eccentric wheel through the positioning piece, and the rotating eccentric wheel converts the rotation of the knob into the linear motion of the locking piece, thereby realizing precise control of the locking piece and achieving locking and unlocking. The transmission structure is simplified, the number of parts is reduced, and the reliability of the system is improved.

[0089] In application, the rotational motion of the knob is converted into the linear motion of the first locking piece 21 through the cooperation of the rotating eccentric wheel and the positioning piece. The mechanical principle of the eccentric wheel is utilized to realize efficient conversion of the motion form. The transmission structure is simplified, the number of parts is reduced, and the reliability of the system is improved. The position of the eccentric hole on the rotating eccentric wheel determines the moving distance of the locking piece. By adjusting the rotation angle of the knob, the displacement of the locking piece can be accurately controlled. Ensure that the locking piece can accurately reach the locking or unlocking position, avoid the problem of excessive movement or not in place. The positioning piece directly transmits the rotational force of the knob to the rotating eccentric wheel. Reduce the loss of force and improve the transmission efficiency of the operating force. Ensure that the force applied by the user can be effectively converted into the motion of the locking piece, reducing the operation difficulty.

[0090] In application, by rotating the first knob 31 forward or backward, the first locking piece 21 can be brought close to or away from the second locking piece 22. Realize the function of bidirectional adjustment of locking and unlocking. Improve the operation flexibility of the connection structure, adapt to different use requirements. The overall structure is compact, saves space, and will not affect the layout of other functional components of the connection seat 10. In other embodiments, customized design is supported, and the eccentricity of the first rotating eccentric wheel 32 or the size of the first knob 31 can be adjusted according to actual needs. Meet the requirements of operating force, displacement range or installation space in different application scenarios, improve the universality and adaptability of the connection structure. Effectively improve the user experience, the knob operation is intuitive and simple, and the user can judge the state of the locking piece by hand feeling. In specific embodiments, the knob side is also provided with a friction-enhancing pattern to facilitate the user to rotate the knob.

[0091] In some embodiments, as Figure 3 and Figure 5As shown, the middle part of the first locking piece 21 is provided with a first mounting hole 212 for mounting the first rotating eccentric wheel 32; the middle part of the second locking piece 22 is provided with a second mounting hole 222 for mounting the second rotating eccentric wheel 42. It ensures that the rotating eccentric wheel can be accurately embedded in the locking piece, avoiding abnormal movement caused by position deviation, and improving the assembly accuracy of the whole connecting structure. The design of the mounting hole firmly fixes the rotating eccentric wheel on the locking piece, preventing the rotating eccentric wheel from loosening or falling off during use. It improves the overall stability and reliability of the connecting structure.

[0092] In some embodiments, as shown in Figure 3 and Figure 5 The first locking piece 21 is provided with a first locking groove 210 on both sides of the first rotating eccentric wheel 32, and the second locking piece 22 is provided with a second locking groove 220 on both sides of the second rotating eccentric wheel 42. Increasing the number of locking grooves can simultaneously cooperate with multiple external connecting parts, which can effectively increase the firmness of the connecting structure when fixing the external connecting parts, improve the locking range and stability of the connecting structure, and also enhance its flexibility, reliability and safety.
