[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled 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.

[0035] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0036] See also Figure 1 to Figure 2, a side locking mechanism provided by an embodiment of the utility model, is applied to the spliced ​​first frame 100 and the second frame 200, and the first frame 100 and the second frame 200 can be used to assemble the display module 420. Among them, the side locking mechanism 300 includes a connecting structure 310, a locking structure 320 and an auxiliary handle 330, wherein the connecting structure 310 is assembled and connected to the side beam of the first frame 100, the locking structure 320 is assembled and connected to the side beam of the second frame 200, the locking structure 320 is snap-connected with the connecting structure 310, the auxiliary handle 330 is rotatably connected with the connecting structure 310, the auxiliary handle 330 can be operated to control the connecting structure 310, and the auxiliary handle 330 is configured to be able to rotate to the plane area where the first frame 100 and the second frame 200 are located.

[0037] In practical applications, the side locking mechanism is applied to the display device 400, but is not limited to the display device 400. The splicing frame 410 of the display device 400 is composed of a plurality of frames, each of which can be equipped with a display module 420. The frame and the display module 420 are combined to form a light box (see Figure 6 ), thus, the display device 400 is usually composed of a plurality of light boxes. In order to conveniently describe the connection relationship between adjacent frames, one of the adjacent frames can be named as the first frame 100, and the other can be named as the second frame 200, and the side locking mechanism 300 is used to enable the first frame 100 and the second frame 200 to be assembled.

[0038] Specifically, when it is necessary to control the connecting structure 310, the auxiliary handle 330 can be rotated from a vertical state to a horizontal state. When rotating, the handle portion 331 of the auxiliary handle 330 is located outside the plane area where the first frame 100 and the second frame 200 are located. Therefore, there is a large activity space around the handle portion 331 of the auxiliary handle 330, and the user can easily operate the auxiliary handle 330 to control the connecting structure 310. For example, the user controls the connecting structure 310 to rotate around the vertical axis through the auxiliary handle 330 to release the restriction of the locking structure 320 on the connecting structure 310, or the user controls the locking shaft of the connecting structure 310 to move up and down through the auxiliary handle 330 to increase the stability between the connecting structure 310 and the locking structure 320, thereby avoiding shaking of the first frame 100 and the second frame 200. If the first frame 100 and the second frame 200 are assembled and installed on a pre-built mounting frame (not shown in the figure), the auxiliary handle 330 can be rotated downward from a horizontal state to a roughly vertical state. The auxiliary handle 330 is located as a whole in the plane area where the first frame 100 and the second frame 200 are located. The auxiliary handle 330 will not interfere with the mounting frame when rotating, thereby facilitating the disassembly and assembly of the first frame 100 and the second frame 200.

[0039] As can be seen from the above, the auxiliary handle 330 is rotatably connected to the connection structure 310. On the one hand, before the side lock mechanism is installed on the mounting frame, the auxiliary handle 330 can be rotated to a horizontal state, and the user can conveniently control the connection structure 310 through the auxiliary handle 330; on the other hand, after the side lock mechanism is installed on the mounting frame, the auxiliary handle 330 can be rotated to a substantially vertical state, and the user can avoid the auxiliary handle 330 from interfering with the mounting frame when rotating. Therefore, the auxiliary handle 330 of the present application not only takes into account the convenience of controlling the connection structure 310, but also takes into account avoiding the interference between the auxiliary handle 330 and the mounting frame.

[0040] In one possible embodiment, referring to Figure 1 and Figure 3 The connection structure 310 includes a locking rod 311 and a locking seat 312, wherein the locking rod 311 is slidably disposed on the first frame 100 along its axial direction, the lower end of the locking rod 311 is the first end, and the first end of the locking rod 311 is connected to the locking seat 312; the upper end of the locking rod 311 is the second end, and the second end of the locking rod 311 is snap-connected to the locking structure 320. The auxiliary handle 330 is rotatably connected to the locking seat 312 around a horizontal axis to be transmission-connected to the locking rod 311, and the auxiliary handle 330 can be operated to control the locking rod 311 to slide up and down along the axial direction.

[0041] Specifically, when the second end of the locking rod 311 is snap-connected with the locking structure 320, there may be an error between the two in the axial direction, which may cause the first frame 100 and the second frame 200 to shake. Based on this, the user operates the auxiliary handle 330, and the auxiliary handle 330 drives the locking rod 311 to move downward. Because the lock seat 312 is against the lower side of the first frame 100, the locking rod 311 can be tightly against the locking structure 320 when moving downward, and the locking rod 311 tightly locks the second frame 200, thereby avoiding the first frame 100 and the second frame 200 from shaking. When the locking structure 320 releases the restriction of the second end, the locking rod 311 moves downward, and the second end of the locking rod 311 is separated from the connecting structure 310 and the second frame 200, thereby completing the disassembly between the first frame 100 and the second frame 200.

[0042] In order to realize that the auxiliary handle 330 drives the locking rod 311 to move up and down, in a specific embodiment, referring to Figure 1 and Figure 3The locking rod 311 is circumferentially fixed to the first frame 100, that is, the locking rod 311 can only slide axially up and down, and cannot rotate circumferentially. The lock seat 312 is provided with a threaded hole along its axial direction, and the first end of the locking rod 311 is threadedly connected to the lock seat 312 through the threaded hole. It can be understood that when strengthening the tightness between the locking rod 311 and the locking structure 320, the user drives the lock seat 312 to rotate circumferentially through the auxiliary handle 330, and the lock seat 312 and the locking rod 311 are circumferentially fixed. Therefore, the lock seat 312 and the locking rod 311 are threadedly rotated, and the first end of the locking rod 311 shrinks toward the lock seat 312 when the lock seat 312 is threadedly rotated. Because the lock seat 312 is pressed against the lower side of the first frame 100 , the lock rod 311 is tightly pressed against the locking structure 320 during the downward movement. Therefore, the lock rod 311 tightly locks the second frame 200 , thereby preventing the first frame 100 and the second frame 200 from shaking.

[0043] In order to realize that the lock seat 312 drives the lock rod 311 to move up and down, in another specific embodiment, the connection structure 310 also includes a transmission assembly (not shown in the figure), which is connected to the lock rod 311 and the auxiliary handle 330. When the auxiliary handle 330 rotates relative to the lock seat 312, the lock rod 311 is controlled to slide axially through the transmission assembly, that is, the lock rod 311 can move up and down. Among them, the transmission assembly can be a connecting rod structure, a gear rack structure, etc. Therefore, when strengthening the tightness between the lock rod 311 and the locking structure 320, the user rotates the auxiliary handle 330 downward, and the auxiliary handle 330 drives the lock rod 311 to move downward through the transmission assembly. Because the lock seat 312 is against the lower side of the first frame 100, the lock rod 311 remains tightly against the locking structure 320, thereby avoiding the first frame 100 and the second frame 200 from shaking.

[0044] For example, the transmission assembly includes a first gear, a second gear and a rack (not shown in the figure), wherein the first gear is arranged on the auxiliary handle 330, the second gear is rotatably arranged on the lock seat 312, the first gear is meshed with the second gear, the rack is arranged on the lock rod 311 along the axial direction of the lock rod 311, and the second gear is meshed with the rack. Specifically, when the auxiliary handle 330 is rotated downward, the auxiliary handle 330 drives the first gear to rotate upward, the first gear drives the second gear to rotate downward, and the second gear drives the rack to rotate downward, thereby driving the lock rod 311 to move downward, and the lock rod 311 remains tightly against the locking structure 320.

[0045] In order to enable the locking rod 311 to maintain the position after sliding downward, in some embodiments, refer to Figure 1 and Figure 3The connection structure 310 further includes a locking bolt 340. A threaded hole is provided on the side of the lock seat 312. The locking bolt 340 is threadedly connected to the side of the lock seat 312 through the threaded hole. The active end of the locking bolt 340 extends into the inner side of the lock seat 312 and abuts against the locking rod 311. It can be understood that when the locking rod 311 moves downward to be tightly abutted against the locking structure 320, the locking bolt 340 is tightened, and the active end of the locking bolt 340 is firmly abutted against the side wall of the locking rod 311, thereby keeping the lock seat 312 and the locking rod 311 relatively fixed, thereby, the first frame 100 and the second frame 200 are firmly assembled together.

[0046] In some embodiments, reference Figure 1 and Figure 3 The connection structure 310 further includes a return spring 350, which is sleeved on the outer side of the lock rod 311, the lower end of the return spring 350 abuts against the lock seat 312, and the upper end of the return spring 350 abuts against the first frame 100. Therefore, when the locking structure 320 releases the restriction on the lock rod 311, the return spring 350 pushes the lock seat 312 to move downward, and the lock seat 312 drives the lock rod 311 downward to separate from the locking structure 320 and the second frame 200, so that the first frame 100 and the second frame 200 can be disassembled. In addition, before the first frame 100 and the second frame 200 are spliced ​​together, the return spring 350 causes the locking rod 311 to be in a retracted state relative to the first frame 100. As a result, during the transportation of the first frame 100, the return spring 350 can effectively prevent the locking rod 311 from generating noise due to shaking. Moreover, the locking rod 311 is in a retracted state relative to the first frame 100, and the locking rod 311 will not interfere with the second frame 200. Therefore, the second frame 200 can be easily assembled with the first frame 100.

[0047] Further, a mounting portion 110 is provided on the side beam of the first frame 100, and a mounting hole is vertically opened in the mounting portion 110 along its axial direction, and the locking rod 311 is axially passed through the mounting hole and is circumferentially fixed to the mounting portion 110, that is, circumferentially fixed to the first frame 100. For example, a protrusion is provided on the side wall of the mounting hole, and a groove is opened in the axial direction of the locking rod 311, and the protrusion is slidably embedded in the groove, thereby, the locking rod 311 is circumferentially fixed to the mounting portion 110.

[0048] In a specific embodiment, referring to Figure 2 and Figure 3The connection structure 310 further includes a guide bolt 360. A guide groove 3111 is provided on the side of the locking rod 311 along its axial direction. The two ends of the guide groove 3111 do not penetrate the two ends of the locking rod 311. The width of the guide groove 3111 is just adapted to the diameter of the guide bolt 360. A threaded hole is provided on the side of the mounting portion 110. The guide bolt 360 is threadedly connected to the side of the mounting portion 110 through the threaded hole. The active end of the guide bolt 360 is embedded in the guide groove 3111. Thus, the guide bolt 360 slides relatively along the guide groove 3111 when the locking rod 311 slides. It can be understood that, when the locking rod 311 slides up and down in the axial direction, the active end of the guide bolt 360 can abut against the two ends of the guide groove 3111. Thus, the guide bolt 360 limits the axial sliding of the locking rod 311 within a set range, thereby preventing the locking rod 311 from detaching from the mounting portion 110. In addition, the guide bolt 360 limits the circumferential rotation of the locking rod 311 through the guide groove 3111, so that the locking rod 311 and the mounting portion 110 are circumferentially fixed; in addition, when the locking rod 311 moves downward and is tightly abutted against the locking structure 320, the user tightens the guide bolt 360, and the active end of the guide bolt 360 is tightly abutted against the locking rod 311, so that the locking rod 311 tightly locks the second frame 200.

[0049] In some embodiments, reference Figure 1 , Figure 3 and Figure 4The locking structure 320 includes a locking seat 321, a stop plate 322 and an elastic member 323, wherein the locking seat 321 is arranged on the side beam of the second frame 200, and the locking seat 321 is provided with a locking hole 3212 along the axial direction of the locking rod 311, and the second end of the locking rod 311 extends into the locking hole 3212. The stop plate 322 includes a pressing portion 3222 and a stopping portion 3221 that are connected to each other. The stopping portion 3221 is slidably arranged between the upper and lower mounting plates 3211 of the locking seat 321 along a direction perpendicular to the locking rod 311 so as to be able to switch between the first position and the second position. The pressing portion 3222 is located on the outer side of the locking seat 321; wherein, a slot 3112 is provided at the second end of the locking rod 311. When the stop portion 3221 is in the first position, the stop portion 3221 is at least partially inserted into the slot 3112 to limit the axial downward sliding of the locking rod 311. In this way, the locking rod 311 is locked by the stop plate 322. The elastic member 323 may be a spring, a tension spring, etc. The elastic member 323 is connected to the locking seat 321 and the stopper 3221, so that the stopper 3221 can be kept in the first position, and the stopper 3221 at least partially remains stuck in the slot 3112 of the locking rod 311 to limit the downward movement of the locking rod 311. In addition, the user can push the stopper 3221 to slide from the first position to the second position through the pressing portion 3222, and the stopper 3221 is separated from the slot 3112, thereby releasing the restriction on the locking rod 311. Under the action of the reset spring 350, the locking rod 311 slides downward away from the connecting seat and the second frame 200, so that the first frame 100 and the second frame 200 can be disassembled.

[0050] In some embodiments, reference Figure 3 and Figure 5 The end of the lock seat 312 away from the lock rod 311 is provided with an L-shaped notch 3121, which runs through the end surface and the side surface thereof, and the rotating portion 332 of the auxiliary handle 330 is rotatably disposed in the notch 3121. It can be understood that when the auxiliary handle 330 is rotated to a horizontal state, the side surface of the rotating portion 332 of the auxiliary handle 330 abuts against the horizontal bottom surface of the notch 3121, so that the auxiliary handle 330 can be kept in a horizontal state, thereby facilitating the user to manipulate the auxiliary handle 330; and when the auxiliary handle 330 is rotated to a vertical state, the side surface of the rotating portion 332 of the auxiliary handle 330 abuts against the vertical side surface of the notch 3121, so that the auxiliary handle 330 can be kept in a vertical state.

[0051] The present application also discloses a display device 400, referring to Figure 6, including the above-mentioned side locking mechanism and the splicing frame 410, wherein the splicing frame 410 includes a plurality of spliced ​​frames, each frame is equipped with a display module 420, and the side locking mechanism is arranged at the opposite side of the adjacent frames. Among them, one of the adjacent frames can be understood as the first frame 100, and the other can be understood as the second frame 200.

[0052] It can be understood that the display device 400 adopts the above-mentioned side locking mechanism. When the display device 400 is spliced, the auxiliary handle 330 can be rotated from a vertical state to a horizontal state. The handle portion 331 of the auxiliary handle 330 is located outside the plane area where the first frame 100 and the second frame 200 are located when rotating. Therefore, there is a large activity space around the handle portion 331 of the auxiliary handle 330, and the user can easily operate the auxiliary handle 330 to control the connecting structure 310. For example, the user controls the connecting structure 310 to rotate around the vertical axis through the auxiliary handle 330 to release the restriction of the locking structure 320 on the connecting structure 310, or the user controls the locking shaft of the connecting structure 310 to move up and down through the auxiliary handle 330 to increase the stability between the connecting structure 310 and the locking structure 320, thereby avoiding shaking of the first frame 100 and the second frame 200, and further avoiding shaking of the assembled display device 400. If the first frame 100 and the second frame 200 are assembled and installed on a pre-built mounting frame (not shown in the figure), the auxiliary handle 330 can be rotated downward from a horizontal state to a roughly vertical state. The auxiliary handle 330 is located as a whole in the plane area where the first frame 100 and the second frame 200 are located. The auxiliary handle 330 will not interfere with the mounting frame when rotating, thereby facilitating the fastening of the display device 400.

It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
