Therefore, they should not be understood as limiting the present application.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of the features.

[0043] It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the conditions under which this application can be implemented. Therefore, they have no substantive technical significance.

[0044] The following embodiments of the present application are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0045] See also Figures 1-6The present application provides a switch lock 100, comprising a base 10, a locking assembly 20 and a rotating assembly 30. Specifically, the base 10 is provided with a receiving cavity 10a and an opening 10b communicating with the receiving cavity 10a. One end of the locking assembly 20 is provided in the receiving cavity 10a, and the other end extends from the opening 10b. The rotating assembly 30 extends into the receiving cavity 10a to be fixed with the locking assembly 20, and the rotating assembly 30 can rotate in the receiving cavity 10a to drive the locking assembly 20 to extend or retract into the receiving cavity 10a to lock or release the display screen. Specifically, when the rotating assembly 30 rotates and drives the locking assembly 20 to extend from the receiving cavity 10a to the opening 10b, the locking assembly 20 extends into the locking structure of the display screen (not shown) to fix the display screen to the switch lock 100. When the rotating assembly 30 rotates and drives the locking assembly 20 to retract into the accommodating cavity 10 a , the locking assembly 20 is released from the display screen.

[0046] It should be noted that in the field of rental display screens, existing methods usually use threaded connections or screws to lock the display screen with the switch lock 100, requiring manual two-handed coordination to achieve installation and removal of the display screen. When the space in which the display screen is used is small, the operator's two hands cannot simultaneously reach into the small space to install and remove the display screen, thereby increasing the difficulty of installation and removal of the display screen and affecting the installation and removal efficiency of the display screen. The above solution only requires rotating the rotating component 30 to switch the switch lock 100 and the display screen between the locked and released states. When installing or removing the display screen in a small space, only one hand needs to be extended to rotate the rotating component 30 to complete the state switching. The operation is simple and convenient, and the installation and removal efficiency is high.

[0047] Furthermore, please combine Figure 2-Figure 4 The base 10 has a bottom wall 11 and a side wall 12 adjacent to the bottom wall 11. The opening 10b is provided on the side wall 12 so that when one end of the locking assembly 20 is placed in the accommodating cavity 10a, the other end can extend out of the opening 10b on the side wall 12 adjacent to the bottom wall 11.

[0048] Furthermore, the locking assembly 20 includes a locking member 21 and a transmission member 22 mounted on the locking member 21. An eccentric hole 11a is defined in the bottom wall 11. One end of the transmission member 22 is fixed to the rotating assembly 30, and the other end extends out of the eccentric hole 11a. When the rotating member 31 rotates, the rotating member 31 drives the transmission member 22 to rotate within the eccentric hole 11a, thereby driving the locking member 21 to extend or retract into the accommodating cavity 10a.

[0049] It should be noted that in the above solution, one end of the transmission member 22 is fixed to the rotating member 31 so that when the rotating member 31 rotates, it can drive the transmission member 22 to rotate. Since the transmission member 22 is arranged on the locking member 21, the transmission member 22 can push the locking member 21 to move when the rotating member 31 rotates. The transmission member 22 is arranged to extend out of the eccentric hole 11a. Therefore, during the process of the transmission member 22 rotating, the transmission member 22 will move within the eccentric hole 11a to achieve a change in position, thereby pushing the locking member 21 to move.

[0050] In one embodiment, the bottom wall 11 is fixed to a bracket or a wall, so that the switch lock 100 is fixed to the bracket or the wall, so that when the display screen is installed or removed from the switch lock 100, the display screen can be installed or removed from the bracket or the wall.

[0051] Further, see Figure 5 The eccentric hole 11a has a first position A and a second position B at opposite ends thereof, and the transmission member 22 extends out of the eccentric hole 11a and moves between the first position A and the second position B in the eccentric hole 11a.

[0052] Furthermore, to enable the locking member 21 to extend or retract from the accommodating chamber 10a during the movement of the transmission member 22, the sidewall 12 has a side surface 12a facing the accommodating chamber 10a, and the distance from the first position A to the side surface 12a is shorter than the distance from the second position B to the side surface 12a. That is, when the transmission member 22 is in the first position A within the eccentric hole 11a, the locking member 21 is retracted within the accommodating chamber 10a or extends a short distance from the accommodating chamber 10a. At this point, the locking member 21 has not yet entered the locking structure of the display screen, thereby maintaining the display screen and the switch lock 100 in an open / closed state. When the display screen needs to be locked to the switch lock 100, the transmission member 22 is rotated to move within the eccentric hole 11a to the second position B. At this point, the locking member 21 extends out of the opening 10b and into the locking structure of the display screen, securing the switch lock 100 to the display screen, thus completing the display screen fixation.

[0053] Specifically, in order to facilitate the movement of the transmission member 22, the above-mentioned eccentric hole 11a is an arc hole, and the rotating member 31 moves along the circumference, so that when the rotating member 31 moves in a circle, the transmission member 22 moves in a circle with the rotating member 31 and can move smoothly in the eccentric hole 11a, thereby preventing the problem of the transmission member 22 being obstructed and difficult to move when the eccentric hole 11a is an irregular hole shape.

[0054] It should be noted that, in the above solution, the fixation of the locking member 21 and the locking structure in the display screen belongs to the existing technology and will not be described in detail here.

[0055] In one embodiment, the line between the first position A and the center of the arc is the first line L1, and the line between the second position B and the center of the arc hole is the second line L2. In order to allow the locking member 21 to extend out of the opening 10b to a sufficient length to be locked in the display screen, the angle between the first line L1 and the second line L2 is 30°-40°. Therefore, when the transmission member 22 moves from the first position A to the second position B, due to the angle of the eccentric hole 11a, the transmission member 22 drives the locking member 21 to extend out of the opening 10b and extend into the locking structure of the display screen.

[0056] In a specific embodiment, the angle between the first line L1 and the second line L2 is 35°, but it is obviously not limited to this. In another embodiment, the angle between the first line L1 and the second line L2 can also be 30°, 31°, 32°, 33°, 34°, 36°, 37°, 38°, 39° and 40°, etc.

[0057] Please combine Figure 2 and Figure 3 To facilitate the movement of the locking member 21 by the transmission member 22, the locking member 21 includes a connecting portion 211 and a locking portion 212 disposed on the connecting portion 211. Specifically, the connecting portion 211 defines a linear hole 211a, through which the transmission member 22 extends, extending from the linear hole 211a and the eccentric hole 11a. The transmission member 22 is movable within the linear groove, while the locking portion 212 extends from the opening 10b into the accommodating cavity 10a. Preferably, the cross-sectional area of ​​the transmission member 22 is less than or equal to the width of the linear hole 211a, enabling the transmission member 22 to move within the linear hole 211a.

[0058] It should be noted that in the above embodiment, because the locking portion 212 extends beyond the opening 10b, when the transmission member 22 moves within the eccentric hole 11a, the locking member 21 is blocked by the opening 10b and does not move laterally with the transmission member 22. The cross-sectional area of ​​the transmission member 22 is less than or equal to the width of the linear hole 211a. Therefore, when the transmission member 22 moves along the eccentric hole 11a toward or away from the display screen, the transmission member 22 pushes against the sidewall 12 of the locking member 21 within the linear groove, driving the locking member 21 toward or away from the display screen, thereby pushing the locking member 21 into the display screen's locking structure to lock it, or pulling the locking member 21 out of the display screen's locking structure to release the display screen and the locking member 21.

[0059] In one embodiment, the connecting portion 211 and the locking portion 212 are welded together, and the connecting portion 211 is roughly a rectangular structure, the locking portion 212 is roughly a cylindrical structure, and the diameter of the locking portion 212 is equal to the diameter of the opening 10b to prevent the locking portion 212 from shaking in the opening 10b when extending or retracting into the opening 10b.

[0060] In one embodiment, the transmission member 22 is substantially a rod-shaped structure, but is obviously not limited thereto. For example, in another embodiment, the transmission member 22 may also be a long rectangular structure.

[0061] Please combine Figure 2 and Figure 3 To facilitate the rotation of the rotating assembly 30 on the base 10, the rotating assembly 30 includes a rotating member 31 and a connecting member 32 disposed on the rotating member 31. Specifically, the base 10 further defines a connecting hole 10c that communicates with the accommodating cavity 10a. The connecting member 32 extends into the connecting hole 10c and can rotate within the connecting hole 10c.

[0062] In one embodiment, the rotating member 31 is generally a long strip-shaped structure, and the connecting member 32 is fixed to the end of the rotating member 31 and extends into the connecting hole 10c, so that the operator can hold the other end of the rotating member 31 and drive the rotating member 31 to rotate. As a result, the operator only needs to reach into a smaller space with one hand to rotate the rotating member 31, thereby extending or retracting the locking member 21 into the accommodating cavity 10a, thereby achieving the locking or loosening of the display screen, facilitating the assembly and disassembly of the display screen.

[0063] In one embodiment, the connecting member 32 is generally a circular pancake-shaped structure of a certain thickness, so as to facilitate insertion from the connecting hole 10c into the accommodating cavity 10a. Thus, when the operator rotates the rotating member 31 away from one end of the connecting member 32, the sidewall 12 of the connecting hole 10c blocks the connecting member 32, allowing the connecting member 32 to rotate within the connecting opening. It is understood that the shape of the connecting member 32 is not limited to this. For example, in another embodiment, the connecting member 32 may also be an ellipsoidal columnar structure.

[0064] Furthermore, to facilitate securing the transmission member 22 to the connecting member 32, in one embodiment, the connecting member 32 defines a securing groove 32a, into which the transmission member 22 extends and is secured. Preferably, to ensure a secure securement of the transmission member 22 and the connecting member 32, after the transmission member 22 extends into the securing groove 32a, the transmission member 22 is secured to the securing groove 32a by welding.

[0065] See also Figure 2 、 Figure 3 and Figure 6To ensure that the rotating member 31 can be rotated only when the display screen is to be installed or removed, the switch lock 100 further includes a locking member 40, an elastic member 50, and a rotating shaft 60. Specifically, a locking groove 31a is defined on the surface of the rotating member 31 facing away from the connecting member 32. The elastic member 50 is sleeved onto the rotating shaft 60, with one end of the elastic member 50 abutting the bottom surface of the locking groove 31a and the other end abutting the locking member 40. The rotating shaft 60 passes through and is fixed to the locking member 40. Both ends of the rotating shaft 60 are rotatably mounted on the sidewalls 12 of the locking groove 31a. When the display screen is to be installed or removed, the locking member 40 can be pressed downward, causing it to press downward on the elastic member 50 along the rotating shaft 60 as a fulcrum, thereby disengaging the locking member 40 from the base 10. At this point, the operator can rotate the rotating member 31 by holding the end of the rotating member 31 away from the connecting member 32 and rotating it.

[0066] Furthermore, to facilitate fastening the rotating member 31 to the base 10, the locking member 40 includes a body 41 and a locking portion 42 disposed on the body 41. Specifically, the rotating member 31 defines a receiving opening 31b that communicates with the locking groove 31a. The locking portion 42 extends from the receiving opening 31b and is fastened to the base 10.

[0067] In one embodiment, the main body 41 includes but is not limited to a rectangular plate, and the locking portion 42 includes but is not limited to a hook structure.

[0068] Furthermore, after the rotating portion rotates to open and close the switch lock 100 and the display screen, in order to maintain the state of the switch lock 100 and the display screen, the base 10 is provided with a first clamping opening 10d and a second clamping opening 10e. The locking portion 42 can be clamped in one of the first clamping opening 10d or the second clamping opening 10e.

[0069] It should be noted that when the transmission member 22 is in the first position A, the locking portion 42 is locked in the second locking opening 10e. At this time, the locking member 21 extends into the locking structure of the display screen, securing the display screen to the switch lock 100. When the display screen needs to be removed, the body 41 is pressed downward, causing the body 41 to lift the locking portion 42 upward along the rotating shaft 60 as a fulcrum, thereby disengaging the locking portion 42 from the accommodating opening 31b and the second locking opening 10e, leaving it suspended in the air. At this time, the operator holds the rotating member 31 away from one end of the connecting member 32, rotates the rotating member 31 to rotate the rotating member 31 and the locking member 40 together until the locking portion 42 is located above the first clamping opening 10d, and loosens the main body 41. The main body 41, driven by the elastic member 50, clamps the locking portion 42 in the first clamping opening 10d to limit the rotation of the rotating member 31, so that the locking member 21 is located in a constant position to maintain the status of the display screen and the switch lock 100, and to prevent the display screen from falling off and being damaged due to the rotation of the rotating member 31 caused by accidental touch.

[0070] In one embodiment, the elastic member 50 includes but is not limited to a torsion spring.

[0071] The above description of the disclosed embodiments is intended to enable one skilled in the art to implement or use the present application. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application is not limited to the embodiments shown herein, but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
