[0007] The locking assembly includes a pin that is movable relative to the locking assembly. The free end of the pin is provided with a latch that cooperates with the latch. The latch and the latch are engaged to fix the display module to the cabinet bracket.

[0008] In some embodiments, the locking assembly further includes a slide groove fixed to the back of the display module and a lock cylinder disposed at one end of the slide groove. The lock cylinder is rotatably disposed relative to the display module, and the pin can slide on the slide groove. The lock cylinder is used to push the pin out of the slide groove and engage with the latch.

[0009] In some embodiments, the lock cylinder includes a rotating shaft rotatably connected to the display module and a handle connected to the rotating shaft. An elliptical rotating component is sleeved on the rotating shaft, and the arcuate sidewall of the elliptical rotating component abuts against the pin. The handle is used to drive the elliptical rotating component to rotate.

[0010] In some embodiments, the elliptical rotating member has a first protrusion at both ends of the major axis of the ellipse protruding from the arc-shaped sidewall, and the pin has a first groove relative to the first protrusion.

[0011] In some embodiments, the elliptical rotating member has a second protrusion near the first protrusion, the second protrusion protruding towards the back of the display module, and a limiting block is provided on the periphery of the rotating shaft. The limiting block is located between the back of the display module and the elliptical rotating member, and the limiting block abuts against the second protrusion to restrict the rotation of the elliptical rotating member.

[0012] In some embodiments, a first clearance groove is provided on the surface of the pin, and a baffle is provided in the first clearance groove. One end of the baffle is fixedly connected to the back of the display module, the side of the baffle abuts against one end of the elastic member, and the other end of the elastic member is connected to the pin.

[0025] Referring Figure 1 and Figure 2 as shown, the present application provides a device for fixing a splicing type LED display screen, including a box body bracket 100;

[0026] a display module 200, the display module 200 includes a display surface and a back surface opposite to the display surface;

[0027] a locking mechanism 300, the locking mechanism 300 includes a locking component 310 installed on the back surface of the display module 200 and a lock catch 320, and the lock catch 320 is arranged on one side of the box body bracket 100 facing the back surface of the display module 200;

[0028] The locking component 310 includes a bolt 311 that can move relative to the locking component 310. A locking tongue 312 cooperating with the lock catch 320 is provided at the free end of the bolt 311, and the locking tongue 312 is inserted and cooperated with the lock catch 320 to fix the display module 200 to the box body bracket 100.

[0029] In this embodiment, the box body bracket 100 has front and rear ends. The front end is used to install the display module 200 and display content through the display module 200. Components such as power supply, control system, and heat dissipation are provided at the rear end to achieve electrical integration and connection, heat dissipation management of multiple display screens. At the same time, it is convenient for quick disassembly and replacement of a single display screen, reducing the maintenance time of the display screen, and forming a relatively movable whole. On one side of the front end of the box body bracket 100 facing the back surface of the display module 200, a lock catch 320 is provided. The lock catch 320 can be symmetrically arranged on the brackets on the opposite two sides of the box body bracket 100 and is fixedly welded or screwed to the box body bracket 100, and at the same time, it corresponds to the locking component 310 on the back surface of the display module 200 in position. Exemplarily, the box body bracket 100 is of a rectangular frame structure, specifically in the shape of a "field", and four display modules 200 are respectively installed at the four corners. The display module 200 is fixedly connected to the box body bracket 100 through the provided locking mechanism 300.

[0030] The display module 200 includes a display surface for image display and a back surface opposite to the display surface. The back surface has multiple mounting holes for mounting the locking component 310, facilitating its installation. The locking component 310 includes a pin 311, which is movable on the locking component 310. One end of the pin 311 is a free end with a locking tongue 312 at its distal end, and the other end is connected to the locking component 310. In one embodiment, the locking component 310 may include a knob-type mechanical drive structure that drives the pin 311 to rotate, allowing the pin 311 to rotate into the latch 320 for fixing. In another embodiment, the locking component 310 may include an elastic drive structure that uses an elastic element 3114 to push the pin 311 into the latch 320 for fixing.

[0031] During assembly, the back of the display module 200 is facing the housing bracket 100, and the locking tongue 312 is aligned with the corresponding latch 320 on the housing bracket 100. When the pin 311 moves relative to the locking component 310, the locking tongue 312 is inserted into the slot of the latch 320, so that the display module 200 is fastened to the housing bracket 100.

[0032] Reference Figure 2 and Figure 3 As shown, in one embodiment, the locking assembly 310 further includes a slide groove 313 fixed to the back of the display module 200 and a lock cylinder 314 disposed at one end of the slide groove 313. The lock cylinder 314 is rotatably disposed relative to the display module 200. The pin 311 can slide on the slide groove 313. The lock cylinder 314 is used to push the pin 311 out of the slide groove 313 and engage with the latch 320.

[0033] In this embodiment, the slide groove 313 is fixedly installed on the back of the display module 200, and is elongated in shape with an open guide rail structure to guide and limit the sliding path of the pin 311. The pin 311 is disposed in the slide groove 313 and can move along the slide groove 313 in a direction parallel to the display module 200. The lock cylinder 314 is installed at one end of the slide groove 313 and is rotatably set relative to the display module 200 via a rotating shaft. The lock cylinder 314 is a knob-type structure, and its interior is provided with an eccentric wheel or cam structure. The outer contour of the cam abuts against the non-free end of the pin 311. When the user rotates the lock cylinder 314, the cam mechanism pushes the pin 311 to slide out along the slide groove 313, causing the latch 312 to be pushed out from the front end of the slide groove 313 and inserted into the latch 320, thereby achieving locking.

[0034] In use, the operator only needs to rotate the lock cylinder 314 from the back of the display module 200 to drive the pin 311 to slide out of the slide groove 313, completing the insertion and engagement of the display module 200 with the cabinet bracket 100, thereby fixing the display module 200. When rotated in the opposite direction, the pin 311 retracts, releasing the locking state. Stops may be provided on both sides of the slide groove 313 to prevent the pin 311 from sliding excessively or falling off. This embodiment, through the combination of the slide groove 313 and the rotating lock cylinder 314, eliminates the need for tools; simply rotating the lock cylinder 314 manually connects the LED display module 200 to the cabinet bracket 100. Compared to traditional screw fixing, this method shortens the assembly and disassembly time and facilitates maintenance.

[0035] Reference Figure 2 and Figure 3 As shown, in one embodiment, the lock cylinder 314 includes a rotating shaft 3141 rotatably connected to the display module 200 and a handle 3143 connected to the rotating shaft 3141. The rotating shaft 3141 is sleeved with an elliptical rotating member 3142. The arc-shaped sidewall of the elliptical rotating member 3142 abuts against the pin 311. The handle 3143 is used to drive the elliptical rotating member 3142 to rotate.

[0036] In this embodiment, one end of the rotating shaft 3141 is rotatably connected to the back of the display module 200 via a bearing or sleeve, and is positioned perpendicular to the direction of the display module 200 and the sliding direction of the pin 311, serving as the rotating shaft for driving rotation. A handle 3143 is mounted on one end of the rotating shaft 3141, allowing manual rotation by the user. The shape of the handle 3143 is not limited, as long as it facilitates rotation by force. The handle 3143 can be switched between a vertical rotation position and a horizontal storage position. An elliptical rotating component 3142 is sleeved on the rotating shaft 3141 and rotates synchronously with it. It is elliptical in shape, has a certain thickness, and its arc-shaped sidewall is the sidewall in the thickness direction, abutting and abutting against the non-automatic end of the pin 311. The working principle is as follows: When the user rotates the handle 3143 in one direction, the rotating shaft 3141 drives the elliptical rotating component 3142 to rotate. As the angle of the elliptical wheel profile changes, its arc-shaped sidewall gradually pushes the pin 311, causing the pin 311 to slide forward out of the front end of the slide groove 313 until the locking tongue 312 on the pin 311 inserts into the latch 320 on the housing bracket 100. After locking, one end of the major axis of the elliptical rotating component 3142 stably abuts against the pin 311, ensuring it is in the locked state. When the handle 3143 is rotated in the opposite direction, one end of the minor axis of the elliptical rotating component 3142 gradually rotates back to the non-free end of the pin 311. The pin 311 retracts under the action of the elastic component 3114, thus unlocking. This makes the pushing process of the pin 311 more stable and reliable, avoiding complex spring or gear mechanisms and improving assembly efficiency and reliability. At the same time, the operation is simple; the user only needs to rotate the handle 3143 to lock or unlock, facilitating maintenance and replacement.

[0037] Reference Figure 2 and Figure 3 As shown, in one embodiment, the elliptical rotating member 3142 has a first protrusion 3144 protruding from the arc-shaped sidewall at both ends of the major axis of the ellipse, and the pin 311 has a first groove 3111 relative to the first protrusion 3144.

[0038] In this embodiment, the two ends of the elliptical profile of the elliptical rotating component 3142, i.e., the two symmetrical endpoints along its major axis, are respectively provided with outwardly extending first protrusions 3144. The two protrusions are hemispherical and can be integrally formed with the elliptical transmission component. At the position near its driving end (i.e., the end that contacts the elliptical rotating component 3142), the pin 311 is provided with two matching first grooves 3111 corresponding to the two first protrusions 3144. The size of each first groove 3111 matches the first protrusion 3144 and is arc-shaped for fitting together. The working principle is as follows: During the rotation of the elliptical rotating component 3142 driven by the handle 3143, the pin 311 is pushed forward by the arc-shaped sidewall. When the rotation angle reaches the locking position, the first protrusion 3144 is aligned and engaged with the first groove 3111 on the pin 311. At this time, the protrusion is inserted into the groove, forming a dual function of mechanical limit and locking positioning. On the one hand, it prevents the pin 311 from rebounding on its own due to vibration or impact. On the other hand, it prompts the user whether the elliptical rotating component 3142 has rotated to the correct position.

[0039] Reference Figure 2 and Figure 3 As shown, in one embodiment, the elliptical rotating member 3142 has a second protrusion 3145 near the first protrusion 3144. The second protrusion 3145 protrudes towards the back of the display module 200. A limiting block 3146 is provided on the periphery of the rotating shaft 3141. The limiting block 3146 is located between the back of the display module 200 and the elliptical rotating member 3142. The limiting block 3146 abuts against the second protrusion 3145 to limit the rotation of the elliptical rotating member 3142.

[0040] In this embodiment, the elliptical rotating member 3142 is provided with a second protrusion 3145 near the first protrusion 3144. The second protrusion 3145 is a columnar protrusion that protrudes towards the back of the display module 200. A limiting block 3146 is installed around the rotating shaft 3141. The limiting block 3146 is located on the back of the display module 200. The elliptical rotating member 3142 is above the limiting block 3146. When rotating, the second protrusion 3145 contacts and abuts against the limiting block 3146, thereby stopping the rotation. The user operates the handle 3143 to drive the rotating shaft 3141 to rotate, and the elliptical rotating component 3142 rotates accordingly, pushing the pin 311 to slide out. When the pin 311 moves to the locking end point, the second protrusion 3145 touches the limit block 3146, and the rotation is mechanically stopped. At this time, the pin 311 has been fully inserted into the latch 320, and the device is in a stable locked state. When the user rotates the handle 3143 in the opposite direction to unlock, the maximum rotation angle is also limited by the limit block 3146 to prevent the elliptical rotating component 3142 from over-reversing.

[0041] Reference Figure 2 and Figure 3 As shown, in one embodiment, a first clearance groove 3112 is provided on the surface of the pin 311, and a baffle 3113 is provided in the first clearance groove 3112. One end of the baffle 3113 is fixedly connected to the back of the display module 200, and the side of the baffle 3113 abuts against one end of the elastic member 3114. The other end of the elastic member 3114 is connected to the pin 311.

[0042] In this embodiment, a first clearance groove 3112 is provided in the middle of the pin 311 along the length direction of the pin 311. The first clearance groove 3112 penetrates the opposite two side surfaces of the pin 311, forming a partial space for installing the baffle 3113 and the elastic member 3114. Inside the first clearance groove 3112, there is a baffle 3113, which is an "L" shape or a sheet metal structure. One end of the baffle 3113 is fixedly connected to the back of the display module 200 by bolts. The side of the baffle 3113 abuts against the elastic member 3114 along the length direction of the pin 311. The elastic member 3114 can be a spring, and its other end is connected to one inner wall of the first clearance groove 3112 on the pin 311 along the length direction. During the sliding process of the pin 311, the relative position of the baffle 3113 in the first clearance groove 3112 continuously changes, causing the elastic element 3114 to be in different compression states. When the display module 200 is not installed, the pin 311 moves away from the latch 320 under the action of the elastic element 3114 until the baffle 3113 abuts against one end of the first clearance groove 3112 along its length, thus limiting the movement of the pin 311. At this point, the pin 311 stops moving, and the length of the elastic element 3114 is the same as the length of the first clearance groove 3112. When the display module 200 needs to be installed, the pin 311 moves towards the latch 320 under the push of the elliptical rotating element 3142, continuously compressing the elastic element 3114 until the locking engagement is completed. The retraction of the pin 311 is achieved by the elastic element 3114, eliminating the need for the user to manually pull it back. The elastic element 3114 and the baffle 3113 are embedded in the first clearance groove 3112, occupying little space.

[0043] Reference Figure 2 and Figure 3 As shown, in one embodiment, the locking assembly 310 further includes a housing 315 that is fixed to the back of the display module 200 by bolts. The housing 315 covers the slide groove 313 and the pin 311 to accommodate the pin 311. A first clearance hole 3151 is provided on the surface of the housing 315, and a rotating shaft 3141 passes through the first clearance hole 3151 to connect to the handle 3143.

[0044] In this embodiment, the housing 315 is a cover-like structure, its shape matching the overall outer contour of the slide groove 313 and the pin 311. It is fixed to the back of the display module 200 by multiple bolts, forming an accommodating space between itself and the display module 200. The accommodating space is used to completely cover the slide groove 313 and the pin 311. The top surface of the housing 315 is provided with a first clearance hole 3151 for the rotating shaft 3141 to pass through. The rotating shaft 3141 passes through the first clearance hole 3151 and extends to the outside of the housing 315 to connect with the handle 3143. The housing 315 covers the slide groove 313 and the pin 311 to prevent dust, debris, etc. from entering and affecting the sliding of the pin 311 or the operation of the elastic element 3114.

[0045] Reference Figure 2 and Figure 3 As shown, in one embodiment, a second clearance hole 3152 is provided on the surface of the housing 315, and a second clearance groove 3115 is provided on the pin 311 relative to the second clearance hole 3152. The bolt passes through the second clearance hole 3152 and the second clearance groove 3115 so that the housing 315 is fixed to the back of the display module 200.

[0046] In this embodiment, at least two second clearance holes 3152 are provided on the surface of the housing 315 parallel to the back of the display module 200. The second clearance holes 3152 are circular holes with a diameter slightly larger than the bolt diameter, for the bolt to pass through. The pin 311 has second clearance grooves 3115 corresponding to the second clearance holes 3152 on both sides of the first clearance groove 3112. The second clearance grooves 3115 extend along the length of the pin 311 to ensure that the bolt does not interfere with the movement of the pin 311 when passing through. The bolt passes through the second clearance holes 3152 and the second clearance grooves 3115 sequentially from the outside of the housing 315, and finally screws into the internal thread seat provided on the back of the display module 200, thereby achieving a fixed connection between the housing 315 and the display module 200.

[0047] Reference Figure 2 and Figure 3 As shown, in one embodiment, there are two locking components 310 and two corresponding latches 320. The two locking components 310 are symmetrically arranged on the back of the display module 200. The pins 311 in the two locking components 310 move towards each other and are respectively engaged with the corresponding latches 320.

[0048] In this embodiment, two locking components 310 are symmetrically arranged on the left and right sides of the back of the display module 200 to improve the fixing effect. Correspondingly, two corresponding latches 320 are provided on the housing bracket 100, located at the left and right ends respectively, facing the back of the display module 200. Two pins 311 are respectively installed in two sliding grooves 313, and their movement direction is opposite, that is, the pins 311 slide from both sides of the display module 200 towards the edges on both sides, and are respectively inserted into the latches 320 located on both sides of the housing bracket 100 to form symmetrical locking. The two pins 311 can be driven simultaneously by rotating the elliptical rotating component 3142 through the same rotating axis 3141. When the elliptical rotating component 3142 rotates, the two ends of its elliptical major axis simultaneously drive the pins 311 to slide. The two locking components 310 can share the load, cope with the weight of the larger module, improve the structural stability, and the symmetrical locking of the pins 311 ensures uniform force and effectively avoids uneven splicing gaps or corner warping of the display module 200.
