[0028] The most common display screens on the market are flat-panel displays. However, with the promotion of display screen applications, display requirements are no longer limited to flat-panel displays, but are developing towards application scenarios such as curved display and corner multi-faceted display. In order to meet such display requirements, in the related prior art, by setting connectors on the left and right sides of the back frame of the display screen, the connectors have specific angle splicing surfaces, so that when the two display screens are spliced ​​and fixed by the connectors, the angle splicing surfaces abut against each other to achieve angle splicing between the two display screens, and achieve curved display effects or corner display effects. However, its angle is fixed and cannot be adjusted, which has certain limitations.

[0029] To this end, the utility model provides a connection lock with multiple angle splicing methods, which can effectively alleviate the problem of limited splicing angles.

[0030] Reference Figures 1 to 6As shown, a connection lock of an embodiment of the utility model comprises a lock block 200, an adjustment block 400 and a connection member 300, wherein the lock block 200 is rotatably arranged, and the lock block 200 is provided with a plurality of splicing surfaces 202 around its own rotation axis, each splicing surface 202 forms a different angle with the rotation axis of the lock block 200, and each splicing surface 202 is provided with a connection structure. The adjustment block 400 is provided with a mounting structure matching the connection structure, and is used for being detachably connected to the splicing surface 202 through the matching of the mounting structure with the connection structure, and an adjustment surface 401 is provided at one end of the adjustment block 400 away from the splicing surface 202, and when the adjustment block 400 is installed on the splicing surface 202, the angle formed by the adjustment surface 401 and the rotation axis of the lock block 200 is different from the angle of the splicing surface 202 relative to the rotation axis of the lock block 200. It is understandable that, assuming that the angle between the splicing surface 202 and the rotating shaft of the locking block 200 is 15°, after the adjusting block 400 is installed, the angle between the adjusting surface 401 and the rotating shaft of the locking block 200 is 20°, that is, the angle of the splicing end is changed. In this embodiment, different splicing surfaces 202 are switched by rotating the locking block 200, so as to achieve angle switching adjustment. Both the splicing surface 202 and the adjusting surface 401 are provided with a keyhole 203. The connecting piece 300 is provided with a locking rod 301 matching the keyhole 203, which is used to be detachably connected to the locking block 200 or the adjusting block 400 through the locking rod 301. It is understandable that in the connection lock of the utility model, first, the locking block 200 is circumferentially provided with a plurality of splicing surfaces 202, and each splicing surface 202 has a different angle, so there are several splicing surfaces 202, that is, there are several different initial splicing angles, and then the splicing is carried out with the connecting piece 300, so that angle splicing can be achieved. On this basis, each splicing surface 202 can be installed with an adjustment block 400 to form a new splicing angle, which can effectively expand the splicing angle range. It is understandable that when the connection lock is applied to a display screen, the lock block 200 and the connector 300 can be correspondingly arranged between two display screens, so that the required splicing angle can be switched by rotating the lock block 200, and the adjustment block 400 can be installed on the splicing surface 202 to change the angle according to actual needs, so that different angles of splicing of the display screen can be achieved, and a curved display effect or a corner display effect can be achieved.

[0031] It should be noted that the angle between the splicing surface 202 and the adjustment surface 401 and the rotation axis of the locking block 200 can be flexibly set. It only needs to be that when applied to display screen splicing, the splicing surface 202 and the adjustment surface 401 can form a matching end surface that meets the angle splicing requirements at the splicing ends of the two display screens, that is, the splicing surface 202 and the adjustment surface 401 can be inclined and extended along the axial direction of the rotation axis of the locking block 200, so that the vertical distance from the axial direction of the rotation axis of the locking block 200 to the splicing surface 202 and the adjustment surface 401 changes, or it can be parallel to the axial direction of the rotation axis of the locking block 200, but the angle formed with the radial direction of the rotation axis of the locking block 200 is different.

[0032] In some embodiments of the present invention, the locking block 200 is provided with a plurality of splicing plates around its own rotation axis, and a splicing surface 202 is formed by the end surface of the splicing plate away from the rotation axis, and a clamping cavity 205 is provided between the end of the splicing plate close to the rotation axis of the locking block 200 and the locking block 200, and a keyhole 203 connected to the clamping cavity 205 is provided on the splicing plate. Figure 4 and Figure 6 The splicing block and the locking block 200 are integrally formed, wherein the locking block 200 forms a plurality of snap-in cavities 205 along the axial direction of its own rotating shaft, and each snap-in cavity 205 passes through the locking block 200, thereby forming a supporting side wall on both sides of each snap-in cavity 205. The outer side of the snap-in cavity 205 forms a splicing plate. It can be understood that, by setting the splicing plate, this embodiment can ensure the structural strength of the splicing surface 202 and can use the snap-in cavity 205 to lock the connector 300. And two adjacent snap-in cavities 205 share a supporting side wall, which helps to reduce consumables and reduce weight.

[0033] It is understandable that, in some embodiments, the adjustment block 400 is also a frame structure, so as to form a chamber inside that penetrates axially along the rotation axis of the locking block 200, thereby facilitating the setting of the keyhole 203 on the outer end surface.

[0034] Reference Figure 2 and Figure 3 In some embodiments of the present invention, the locking rod 301 is rotatably arranged to be engaged in the keyhole 203 by rotation, and a stopper 206 is arranged on the other end surface of the splicing plate opposite to the splicing surface 202. The stopper 206 is protrudingly arranged on the splicing plate and located on one side of the keyhole 203, and is used to limit the rotation of the locking rod 301. With the structural arrangement of this embodiment, after the locking rod 301 is inserted into the keyhole 203, it can be rotated to be misaligned with the keyhole 203 to achieve engagement, and during the rotation, the stopper 206 is used to limit the rotation, which is convenient for operation.

[0035] Reference Figure 2 and Figure 3 In some embodiments of the present invention, both the splicing surface 202 and the adjustment surface 401 are provided with a positioning recess 204, and the end surface of the connector 300 is provided with a positioning protrusion 302 that matches the positioning recess 204. The positioning recess 204 and the positioning protrusion 302 are used to quickly position the connector 300 and the locking block 200, and cooperate with the locking rod 301 and the keyhole 203 to improve the splicing strength and stability.

[0036] In some embodiments of the present invention, the connection lock further includes an adjustment mechanism, which is connected to the lock block 200 and is used to control the rotation of the lock block 200 and lock the lock block 200 when each splicing surface 202 is at a set angle. Since the lock block 200 in the present invention is provided with a plurality of splicing surfaces 202, the splicing surfaces 202 are switched by rotation, and when applied to display screen splicing, the splicing surfaces 202 need to provide an angle docking function, so it is necessary to ensure the stability of the splicing surfaces 202. By providing an adjustment mechanism, this embodiment can ensure that the position of the splicing surface 202 is stable when the desired splicing surface 202 is adjusted by locking the lock block 200.

[0037] In some embodiments of the utility model, the adjustment mechanism is a threaded locking structure, which is used to lock the locking block 200 by tightening and to rotate the locking block 200 by loosening. Specifically, the adjustment mechanism includes an adjustment knob 201 connected to the locking block 200 in an angle-fixed manner and a locking screw that can move closer to or farther from the locking block 200. The adjustment knob 201 is fixed to the locking block 200 in an angle manner, so the rotation of the adjustment knob 201 can control the rotation of the locking block 200 to switch the splicing surface 202. At the same time, after the switching is completed, the locking screw can be controlled to approach the locking block 200 to tighten and lock it, so as to fix the splicing surface 202. It can be understood that since the connection lock is used for display screen assembly, its installation body is the display screen, and the adjustment knob 201 and the locking screw in this embodiment are both installed on the display screen.

[0038] In some embodiments of the utility model, the adjustment mechanism is an elastic supporting structure, which is used to lock the locking block 200 by elastic supporting. Specifically, the adjustment mechanism includes an adjustment knob 201, a reset spring, a rotational recess and a rotational convex portion, wherein the adjustment knob 201 is connected to the locking block 200 in a fixed angle manner, and is used to control the rotation of the locking block 200. The rotational convex portion is formed on the locking block 200 and is distributed around the rotation axis of the locking block 200. The rotational convex portion is provided with inclined surfaces at both ends of the rotation direction, and the rotational recess is formed on an adjustment plate. Under the action of the reset spring, the locking block 200 keeps the rotational convex portion fitted into the rotational recess, so that the locking block 200 is in a state where a certain splicing surface 202 is fixed. When the adjustment knob 201 is rotated, the rotational convex portion automatically exits the rotational recess under the action of force and enters the next rotational recess, thereby realizing the switching of the splicing surface 202.

[0039] In some embodiments of the present invention, the connection structure includes a threaded hole opened on the joint surface 202, and the mounting structure includes mounting screws, that is, the adjustment block 400 is detachably mounted on the joint surface 202 by the mounting screws.

[0040] The utility model further provides a display screen, comprising a screen body 100 and a connecting lock of any of the above embodiments, wherein a locking block 200 and a connecting member 300 are correspondingly arranged on opposite sides of the screen body 100 to realize splicing between two screen bodies 100.

[0041] Reference, 1 to Figure 6 In some embodiments, the screen body 100 is provided with a back frame, a connector 300 is provided on the left side of the back frame, and a locking block 200 is provided on the right side. Specifically, a mounting cavity with an opening at the right end is provided on the right side of the back frame, and the locking block 200 is rotatably provided in the mounting cavity. A mounting shaft hole is provided at the center of the rotating shaft of the locking block 200. A rotating shaft passing through the mounting shaft hole is rotatably provided in the mounting cavity, and the rotating shaft extends to the back of the mounting cavity and is provided with an adjustment knob 201. The rotating shaft and the locking block 200 are fixed at an angle by a pin. The locking block 200 is provided with a sliding groove corresponding to the pin, so that it can be moved and adjusted along the axial direction of the rotating shaft. A reset spring is provided between the locking block 200 and one side wall of the mounting cavity in the axial direction, and a matching rotating concave and rotating convex portion are provided between the other side wall, so that the locking block 200 is held by the reset spring under normal conditions, so that the rotating convex portion and the rotating concave portion cooperate to achieve the relative angle fixation of the locking block 200. And in each angle fixed state, a splicing surface 202 is exposed at the right end of the mounting cavity. The connector 300 adopts a telescopic rotation structure, which is used to be inserted into the keyhole 203 by axial telescopic movement and to be engaged by rotation. The specific structure can be set with reference to the relevant prior art, and will not be described in detail here.

[0042] It is understandable that, with the structural setting of this embodiment, if the locking block 200 is set to have four splicing surfaces 202, the splicing angles of the four splicing surfaces 202 are 5°, 10°, 20°, and 30° respectively, and the preset splicing angle of the adjustment block 400 is 5°, when the adjustment block 400 is respectively installed on the four splicing surfaces 202, the angles of the final adjustment surface 401 are 10°, 15°, 25°, and 35° respectively. Therefore, the display screen in the utility model can achieve splicing at various angles to meet application requirements by applying the aforementioned connection lock. And one or more adjustment blocks 400 can be customized as needed to further increase the splicing angle range, with a simple structure and low production cost.

[0043] The present invention is described in detail above in conjunction with the embodiments, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
