[0026] In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the specific implementation methods of the present invention are further described in detail below in conjunction with the drawings and examples. The following examples are used to illustrate the present invention but are not used to limit the scope of the present invention.

[0027] like Figure 1 and Figure 5 As shown, the hybrid display frame described in the present invention quickly combines multiple frames of different structures and types to meet the diverse needs of display frames, including a main frame 1, a first side frame 2, a second side frame 3 and a connecting piece for connecting the main frame 1, the first side frame 2 and the second side frame 3.

[0028] The connecting member includes two connecting parts 4 and a first locking member 5 and a second locking member 6 corresponding to each connecting part 4. It can be understood that the connecting member as a whole can be in a straight line structure or an L-shaped structure. When it is in a straight line structure, the two connecting parts 4 are located in the same plane; when it is in an L-shaped structure, the two sets of frames are connected at the corners of the two connecting parts 4; the first locking member 5 and the second locking member 6 can be the same or different.

[0029] In this embodiment, the first locking member 5 and the second locking member 6 are different.

[0030] like Figures 2 to 4The main frame 1 includes a main frame bar 11 with a T-shaped groove 111, one of the connecting parts 4 is provided with a through hole 41 connected to the main frame 1; the first locking member 5 includes a rotating handle 51, a clamping part 52 and a connecting rod 53 connecting the rotating handle 51 and the clamping part 52, and the connecting rod 53 is passed through the through hole 41.

[0031] The clamping portion 52 is installed in the T-shaped groove 111 of the main frame bar 11 for connecting to the main frame bar 11 and extends outside the T-shaped groove 111 through the connecting rod 53 to connect to the rotary handle 51. The end surface of the clamping portion 52 connected to the connecting rod 53 has a clamping platform 521, which is engaged with the T-shaped groove 111 of the main frame bar 11 through the clamping platform 521.

[0032] Furthermore, the connecting rod 53 has a cylindrical structure, and the clamping portion 52 has two opposite side surfaces along the axial direction of the connecting rod 53, and the radial distance between the two opposite side surfaces is not greater than the diameter of the connecting rod 53, so that the clamping portion 52 and the connecting rod 53 can be placed together in the T-shaped groove 111 of the main frame bar 11.

[0033] The end portion of the connecting rod 53 connected to the rotating handle 51 is provided with a pin hole that penetrates therethrough. The rotating handle 51 includes a cam portion 511 and a wrench portion 512. The cam portion 511 is provided with a pin hole 513 corresponding to the pin hole. The pin hole 513 is eccentrically arranged with respect to the cam portion 511. The pin is sequentially inserted into the pin hole and the pin hole 513 to rotatably connect the rotating handle 51 to the connecting rod 53.

[0034] When in use, the clamping portion 52 and the connecting rod 53 are placed together in the T-shaped groove 111 of the main frame strip 11. After the rotating handle 51 is rotated 90° along the circumferential direction of the connecting rod 53, the clamping portion 52 rotates with the rotating handle 51 and is clamped with the T-shaped groove 111 through the clamping platform 521. Then, the rotating handle 51 is bent 90° relative to the connecting rod 53 through the wrench portion 512. At this time, the cam portion 511 rotates and presses the connecting portion 4, while driving the connecting rod 53 to move axially so that the clamping platform 521 is against the inner wall of the T-shaped groove 111, thereby realizing the rapid locking and fixation of the connecting rod 53 and the main frame strip 11.

[0035] like Figures 6 to 8The second locking member 6 includes a snap lock member 61 that cooperates with the first locking member 5 to connect the first side frame 2 to the main frame 1, and a clamp lock member 62 that cooperates with the first locking member 5 to connect the second side frame 3 to the main frame 1. Specifically, the first side frame 2 is composed of a plurality of first side frame bars 21, and the first side frame bars 21 have a left snap groove and a right snap groove. The left snap groove and the right snap groove both have a convex edge 211 for the snap lock member 61 to engage with. The convex edge 211 extends in the same direction as the first side frame bars 21. Specifically, the snap lock member 61 includes a snap portion 611 that engages with the convex edge 211 and a mounting portion 612 connected to the snap portions 611 on both sides. The mounting portion 612 is connected to the corresponding connecting portion 4 by bolts. The opposite end surfaces of the snap portions 611 on both sides have a snap groove 613 for snapping with the convex edges 211 on both sides.

[0036] During installation, first install the connecting piece at the corresponding position of the main frame strip 11 through the first locking piece 5, then place the first side frame strip 21 side by side on the adjacent side of the main frame strip 11 and make the convex edge 211 correspond to the snap portion 611, and apply a clamping force toward the installation portion 612 to the corresponding connecting portion 4, so that the snap portion 611 is elastically deformed, and the convex edge 211 is squeezed into the snap groove 613 along the guide slope 614 of the snap portion 611 to complete the fastening.

[0037] The second side frame 3 is composed of a plurality of cylindrical second side frame bars 31. The clamp locking member 62 is a semicircular clamp structure 621 with an opening on one side. A mounting block 622 is provided on the side of the clamp structure 621 facing away from the opening. The mounting block 622 is bolted to the corresponding connecting portion 4. Specifically, a guide arc 623 is provided at the opening of the clamp structure 621. Under the guidance of the guide arc 623, the second side frame bar 31 and the clamp structure 621 are pressed toward each other to achieve engagement.

[0038] Furthermore, anti-skid protrusions 624 are evenly provided on the inner wall of the clamp structure 621. The anti-skid protrusions 624 are used to improve the anti-skid performance of the second side frame bar 31 after installation, and prevent the second side frame bar 31 from moving axially after installation.

[0039] The second side frame strip 31 engages the clamp structure 621, allowing the second side frame strip 31 to rotate about its axis and rotate within the semicircle of the clamp structure 621. During display, this structure allows the connection angle between the second side frame 3 and the other connected frame to be flexibly adjusted as needed. After use, the second side frame 3 and the other connected frame can be temporarily folded and stored by rotation, and then rotated open to the desired angle for further use.

[0040] When using this connector to connect multiple different types of frames, no tools are required during the installation and disassembly process. The disassembly and assembly are flexible and convenient, simple and fast, and the connection is firm and reliable, not easy to loosen. It can be quickly spliced to form corresponding multiple frame structures, and is especially suitable for the rapid assembly of various display frames and other frames.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
