[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0037] Please refer to Figure 1 , which is a schematic exploded view of a three-dimensional structure of a connecting lock provided by an embodiment of the present utility model, wherein the connecting lock includes a base 10, two handles 20, two lock hooks 30 and two first torsion springs 40.

[0038] The base 10 has a first surface 110 and a second surface 120 that are perpendicular to each other;

[0039] Each handle 20 has a U-shaped connecting end 210 and an operating end 220 at both ends. The two U-shaped connecting ends 210 are hinged to the base 10 below the first surface 110 and the second surface 120 respectively. The two locking hooks 30 are respectively disposed in the two U-shaped connecting ends 210, with one end extending above the first surface 110 and the second surface 120 and the other end hinged to the U-shaped connecting end 210.

[0040] The two first torsion springs 30 are respectively mounted on the U-shaped connecting end 210 and the first hinge shaft 310 of the locking hook 30 , with one end abutting against the U-shaped connecting end 210 and the other end abutting against the locking hook 30 .

[0041] Specifically, please combine Figure 2-6The base 10 can be an L-shaped structure, the first surface 110 and the second surface 120 are connected to each other and perpendicular to each other, and the handle 20 is provided on the first surface 110 and the second surface 120, one end of each handle 20 is the U-shaped connecting end 210 with a U-shaped opening, and the other end is the operating end 220 for operation, wherein the U-shaped connecting end 210 extends toward the base 10 and is hinged to the base 10 below the first surface 110 or the second surface 120, so that the handle 20 can rotate relative to the base, and the two locking hooks 30 are respectively connected to the U-shaped openings of the two U-shaped connecting ends 210. The connection method is also hinged, that is, the first hinge axis 310 passes through the U-shaped connecting end 210 and the end of the locking hook 30 in sequence to complete the hinged connection between the locking hook 30 and the handle 20, and the ends of the two locking hooks 30 away from the first hinge axis 310 extend above the first surface 110 and the second surface 120, and the ends are used to connect to the display screen frame; two first torsion springs 30 are respectively arranged between the two U-shaped connecting ends 210 and the locking hooks 30, that is, the first torsion spring 30 is sleeved on the first hinge axis 310, one end of which abuts against the U-shaped connecting end 210, and the other end abuts against the locking hook 30.

[0042] like Figure 5 、 6 As shown, the connecting lock of the embodiment of the present invention is placed at the connection between the display frame 11 and the display frame 12 when in use. The display frame 11 and the display frame 12 are perpendicular to each other. The first surface 110 and the second surface 120 of the base 10 are respectively arranged to face the back of the display frame 11 and the display frame 12. By rotating the handle 20, the lock hook 30 is driven to rotate together, so that the ends of the two lock hooks 30 away from the first hinge axis 310 hook the connecting rods on the back of the display frame 11 and the display frame 12. In this way, the display frame 11 and the display frame 12 are connected and fixed together through the base 10 (that is, the connecting lock), and the two are kept perpendicular to each other. That is, by using the connecting lock, the connection between two display screens at a 90-degree angle can be achieved, thereby expanding the use scenarios of LED display screens.

[0043] Furthermore, in other preferred embodiments of the present invention, the two first hinge shafts 310 are respectively located below the first surface 110 and the second surface 120, and the hinge point between the U-shaped connecting end 210 and the base 10 is located on the side of the first hinge shaft 310 facing the base 10.

[0044] Specifically, the U-shaped connecting end 210 and the base 10 are also hinged by a rotating shaft, and the rotating shaft is located below the first surface 110 and the second surface 120. Similarly, the first hinge axis 310 is also arranged below the first surface 110 and the second surface 120, that is, the hinge point (the rotating shaft) of the U-shaped connecting end 210 and the base 10 and the first hinge axis 310 are located on the same side of the first surface 110 and the second surface 120, but the hinge point (the rotating shaft) of the U-shaped connecting end 210 and the base 10 is closer to the first surface 110 and the second surface 120 than the first hinge axis 310, that is, the hinge point of the U-shaped connecting end 210 and the base 10 is located on the side of the first hinge axis 310 facing the base 10. Such a design can ensure that when the handle 20 is rotated, the end of the locking hook 30 away from the hinge point can be driven to move toward the first surface 110 or the second surface 120, so as to fasten the connecting rod on the display frame.

[0045] In addition, in other preferred embodiments of the present invention, the connecting lock further includes two second torsion springs 50 and two V-shaped locking members 60, and the middle portion of the locking member 60 is hinged to the handle 20 via a second hinge shaft 610;

[0046] The second torsion spring 50 is sleeved on the second hinge shaft 610 , with one end connected to the handle 20 and the other end abutting against the locking member 60 ;

[0047] One end of the locking member 60 is located above the handle 20 and is a pressing end 620 , and the other end thereof extends toward the base 10 and is a locking end 630 capable of abutting against an edge of the base 10 .

[0048] Specifically, the middle parts of the two V-shaped locking members 60 are hingedly connected to the handle 20, that is, the second hinge axis 610 passes through the middle part of the locking member 60 and the handle 20 in sequence, one end of the locking member 60 is the pressing end 620 placed above the handle 20, and the other end extends toward the base 10 and is capable of abutting against the edge of the base 10 as the locking end 630. By pressing the pressing end 620, the locking member 60 can be rotated so that the locking end 630 approaches the edge of the base 10 and abuts against it to complete the locking of the handle 20. In addition, the second hinge shaft 610 is also provided with a second torsion spring 50, one end of which is connected to the handle 20, and the other end abuts against the locking member 60. The second torsion spring 50 can provide a torque to bring the locking end 630 and the edge of the base 10 closer to each other when they abut against each other, thereby ensuring the reliability of the two when they abut against each other, and further ensuring the reliability of the locking member 60 locking the handle 20.

[0049] Furthermore, when the handle 20 rotates away from the locking hook 30 , the locking member 60 is driven to rotate together, so that the locking end 630 abuts against the edge of the base 10 .

[0050] Specifically, when the handle 20 rotates about its hinge point relative to the lock base 10, specifically in a direction away from the locking hook 30, the handle 20 drives the locking member 60 to rotate together. When the locking hook 30 hooks onto the connecting rod on the display frame, the locking end 630 abuts against the edge of the base 10, thereby locking the handle 20. To unlock it, simply press the pressing end 620 downward to rotate the locking member 60 so that the locking end 630 moves away from the edge of the base 10, releasing the lock on the handle 20. Then, by rotating the handle 20 in the opposite direction, the locking hook 30 can be disengaged from the connecting rod on the display frame.

[0051] Furthermore, the edge of the handle 20 has a first limiting groove 401 for the end of the first torsion spring 40 to be inserted into; the edge of the locking member 60 has a second limiting groove 501 for the end of the second torsion spring sleeve 50 to be inserted into.

[0052] Specifically, the first limiting groove 401 is opened on the outer edge of the handle 20, and the second limiting groove 501 is opened on the outer edge of the locking member 60. The middle part of the first torsion spring 40 is sleeved on the first hinge shaft 310, and the end located inside abuts against the locking hook 30, and the end located outside is arranged on the outer edge of the handle 20. When the locking hook 30 rotates, its outer end can be immersed in the first limiting groove 401; the middle part of the second torsion spring 40 is sleeved on the second hinge shaft 610, and the end located inside abuts against the handle 20 to form a fixed connection, and the end located outside is arranged on the outer edge of the locking member 60. When the locking member 60 rotates, its outer end can be immersed in the second limiting groove 501.

[0053] Furthermore, the second hinge axis 610 is located on the side of the first hinge axis 310 away from the base 10, and the hinge point between the U-shaped connecting end 210 and the base 10, the first hinge axis 310 and the second hinge axis 610 are distributed in a triangular shape.

[0054] Specifically, the side surface of the U-shaped connecting end 210 is a triangular structure, and the three vertices are the hinge point between the U-shaped connecting end 210 and the base 10, the setting position of the first hinge axis 310, and the setting position of the second hinge axis 610, so that the second hinge axis 610 is located on the side of the first hinge axis 310 away from the base 10.

[0055] In addition, in other preferred embodiments of the present invention, the base 10 further has a third surface 130 perpendicular to both the first surface 110 and the second surface 120;

[0056] The base 10 below the third surface 130 is also provided with a handle 20 , whose two ends are the U-shaped connecting end 210 and the operating end 220 , and the U-shaped connecting end 210 is hinged to the base 10 below the third surface 130 ;

[0057] The locking hook 30 is also provided in the U-shaped connecting end 210 , one end of which extends above the third surface 130 , and the other end of which is also hinged to the U-shaped connecting end 210 via the first hinge shaft 310 ;

[0058] A first torsion spring 40 is also sleeved on the first hinge shaft 310 , one end of which abuts against the U-shaped connecting end 210 , and the other end of which abuts against the locking hook 30 .

[0059] Here, the connecting lock in the above embodiment is suitable for the scenario where two display screens are connected to each other and form a 90-degree angle, but in actual applications, three display screens will be connected to each other, and there will be a 90-degree angle between each other. In this case, it is necessary to add the third surface 130 to the base 10, and the handle 20 is also provided below the third surface 130. The structure of the handle 20 is the same as the structure of the handle 20 provided below the first surface 110 or the second surface in the above embodiment. The handle 20 is also provided with the same lock hook 30 as in the above embodiment. The specific shapes and connection relationships of these structures are not repeated here, and reference can be made to the above embodiments.

[0060] Furthermore, the handle 20 located on the third surface 130 is also provided with a second torsion spring 50 and a V-shaped locking member 60;

[0061] The middle portion of the locking member 60 is hinged to the handle 20 via a second hinge shaft 610;

[0062] The second torsion spring 50 is sleeved on the second hinge shaft 610 , with one end connected to the handle 20 and the other end abutting against the locking member 60 ;

[0063] One end of the locking member 60 is located above the handle 20 and is the pressing end 620 , and the other end extends toward the base 10 and is the locking end 630 capable of abutting against the edge of the base 10 .

[0064] Specifically, the handle 20 is further provided with the second torsion spring 50 and the locking member 60 having the same structure as the above embodiment. The specific shapes and connection relationships of these structures are not described here in detail. Please refer to the description of the above embodiment for details.

[0065] like Figure 5 、 6 As shown, the connecting lock of the embodiment of the present invention is placed at the connection of the display screen frame 11, the display screen frame 12 and the display screen frame 13 when in use, and the three display screens are in a perpendicular relationship between two. The first surface 110, the second surface 120 and the third surface 130 of the base 10 are respectively arranged to face the back of the display screen frame 11, the display screen frame 12 and the display screen frame 13. By rotating the three handles 20, the three locking hooks 30 are respectively driven to rotate together, so that the ends of the three locking hooks 30 away from the first hinge axis 310 hook the connecting rods on the back of the display screen frame 11, the display screen frame 12 and the display screen frame 13. In this way, the three display screens are connected and fixed together through the base 10 (that is, the connecting lock), and can maintain a perpendicular relationship between two of them, that is, by using the connecting lock, the connection between display screens at a 90-degree angle can be achieved, further expanding the use scenarios of LED display screens.

[0066] Furthermore, in other preferred embodiments of the present invention, positioning protrusions 101 are provided on the first surface 110 , the second surface 120 and the third surface 130 .

[0067] Here, after the positioning protrusions 101 are provided on the first surface 110, the second surface 120 and the third surface 130, when the connecting lock is placed at a position where the backs of the display screen frame 11, the display screen frame 12 and the display screen frame 13 are connected to each other, the positioning protrusions 101 can be inserted into the positioning grooves on the back of the display screen, thereby completing the preliminary positioning of the connecting lock on the display screen frame.

[0068] Furthermore, each locking hook 30 is provided at an end away from the first hinge shaft 310 with a bay groove 301 opening toward the first surface 110 , the second surface 120 and the third surface 130 .

[0069] Specifically, a bay groove 301 is provided at the end of each locking hook 30 away from the first hinge axis 310, and the opening direction of the bay groove 301 is respectively toward the first surface 110, the second surface 120 and the third surface 130, and the bay groove 301 can easily hook out the connecting rod on the display screen frame, thereby completing the connection between the connecting lock and the display screen.

[0070] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the embodiments of the present invention, rather than to limit them.
