Referring to fig. 1, a retaining mechanism 1000 according to an embodiment of the present disclosure will be described. The retaining mechanism 1000 is used to attach the first structure 2000 to the second structure 3000. In this embodiment, the first structural member 2000 is an LED display module in an LED display screen, the second structural member 3000 is a box, and the anti-falling mechanism 1000 is used to mount the LED display module on the box, so as to prevent the LED display module from falling off from the box due to being separated from the box. It is understood that, in other embodiments of the present application, the above-mentioned anti-dropping mechanism 1000 may also be used elsewhere, for example, for hanging a television on a wall, or for installing an outer wall on a wall base, which is not limited herein.

Referring to fig. 2 to 6, the anti-falling mechanism 1000 includes a fixed base 100, a movable base 200 and a locking element 300. Wherein the fixing base 100 is configured to be fixedly mounted on the first structural member 2000; the movable seat 200 is movably mounted on the second structural member 3000; sliding seat 200 can insert in fixing base 100 in order to form normal running fit with fixing base 100, and sliding seat 200 can form the joint with fixing base 100 after forward rotation, and sliding seat 200 can unblock the joint with fixing base 100 after the reverse rotation.

The forward direction and the reverse direction referred to herein are not specified directions, and the forward direction and the reverse direction are two opposite directions of rotation. When the movable seat 200 is rotated along a direction, and then can form a snap connection with the fixed seat 100, the direction is a forward direction, for example, as indicated by a forward arrow in fig. 4; when the movable seat 200 is rotated in another direction to unlock and clamp with the fixed seat 100, the other direction is the reverse direction, for example, as indicated by the reverse arrow in fig. 4.

In addition, the movable seat 200 can be clamped with the fixed seat 100 only by rotating by a certain angle in the positive direction, which can be set according to the actual structure; the movable seat 200 may be capable of forming a snap connection with the fixed seat 100 by rotating a small angle after inserting the fixed seat 100, or the movable seat 200 may be capable of forming a snap connection with the fixed seat 100 after inserting the fixed seat 100 and then rotating a first preset angle.

Similarly, the movable seat 200 can be unlocked and clamped with the fixed seat 100 at a certain angle of reverse rotation, which is generally seen from the angle of forward rotation of the movable seat 200, when the movable seat 200 rotates forward 10 degrees and then forms a clamping connection with the fixed seat 100, the movable seat 200 can be unlocked and clamped with the fixed seat 100 after rotating backward 10 degrees.

When the first structural member 2000 is mounted on the second structural member 3000 using the retaining mechanism 1000, the fixing base 100 is first fixedly mounted on the first structural member 2000; next, the locking member 300 is mounted on the movable base 200, and the movable base 200 is movably mounted on the second structural member 3000; then, inserting the movable seat 200 into the fixed seat 100 to form a rotating fit with the fixed seat 100, and rotating the movable seat 200 in the forward direction until the movable seat 200 and the fixed seat 100 form a clamping connection, so as to mount the first structural member 2000 on the second structural member 3000; finally, the locking member 300 is moved to form a connection with the fixed base 100 to prevent the movable base 200 from rotating, thereby preventing the movable base 200 from rotating reversely from the fixed base 100 to unlock the clamping.

When the first structural member 2000 needs to be separated from the second structural member 3000, the locking member 300 is moved and is connected with the fixed seat 100 in an unlocking manner; then, the movable seat 200 is rotated reversely to unlock the clamping with the fixed seat 100, so that the movable seat 200 is taken out of the fixed seat 100 to separate the first structural member 2000 and the second structural member 3000.

The anti-falling structure provided by the embodiment of the application comprises a fixed seat 100 and a movable seat 200, wherein the fixed seat 100 is fixedly arranged on a first structural member 2000, the movable seat 200 is movably arranged on a second structural member 3000, the movable seat 200 can be inserted into the fixed seat 100 to form a rotating fit with the fixed seat 100, and the movable seat 200 can be clamped with the fixed seat 100 after rotating in the positive direction, so that the first structural member 2000 can be arranged on the second structural member 3000; and the movable seat 200 can be unlocked and clamped with the fixed seat 100 after being rotated reversely, so that the first structural member 2000 can be detached from the second structural member 3000. Meanwhile, through the arrangement of the locking member 300, after the movable seat 200 is clamped with the fixed seat 100, the locking member 300 can lock the movable seat 200 to prevent the movable seat 200 from reversely rotating and separating from the fixed seat 100, so as to prevent the first structural member 2000 from separating from the second structural member 3000, and further ensure the connection firmness of the first structural member 2000 and the second structural member 3000. To sum up, when using the original magnetism of anti-disengaging mechanism cooperation of this application to inhale the structure and come LED display module assembly to install on the box, when guaranteeing that LED display module assembly and box dismantle the convenience, can fully improve LED display module assembly and box and be connected fixed reliability.

In one embodiment, referring to fig. 3 to 8, an insertion hole 110 is formed on the fixing base 100, a plurality of stoppers 120 distributed along a circumferential direction are disposed on an inner wall of the insertion hole 110, and a guide groove 130 is formed between two adjacent stoppers 120; a plurality of clamping blocks 210 distributed along the circumferential direction are arranged on the outer wall of one end of the movable seat 200; one end of the movable seat 200 can be inserted into the insertion hole 110, each latch 210 can be inserted into each guide groove 130, and each latch 210 can be inserted into a predetermined depth and then rotated in a forward direction along with the movable seat 200 to form a snap connection with each latch 120.

After the latch 210 is inserted into the guide groove 130 to a predetermined depth, the latch 210 is located on the inner end surface of the guide groove 130, that is, each of the latches 120 does not limit the latch 210 in the circumferential direction, so that the movable seat 200 can rotate in the fixed seat 100. After the movable seat 200 rotates in the forward direction, each latch 210 can be correspondingly engaged with each stopper 120 one by one, specifically, each latch 210 is stopped at the inner side of each stopper 120, so as to prevent the movable seat 200 from being axially taken out of the fixed seat 100.

It should be noted that the preset depth is the axial length of the stopper 120; when the fixture block 210 is inserted between adjacent stops 120, the stops 120 form a circumferential limit on the fixture block 210, when the insertion depth of the fixture block 210 reaches the axial length of the stops 120, the fixture block 210 and the stops 120 are separated from each other in the circumferential direction, and the stops 120 cannot form a circumferential limit on the fixture block 210, so that the movable seat 200 can rotate in the fixed seat 100; after the fixing base 100 rotates by a first preset angle, each latch 210 rotates to the inner side of each stopper 120, so that each stopper 120 axially limits each latch 210, and thus the fixing base 100 and the movable base 200 axially limit each other, and in addition, the locking member 300 circumferentially limits the movable base 200, and thus the movable base 200 can be fixed on the fixing base 100, and thus the first structural member 2000 and the second structural member 3000 form a connection and cannot be separated from each other.

Referring to fig. 7, each stopper 120 is formed by extending axially from an axial end surface of the insertion hole 110 to the inside of the insertion hole 110, that is, each stopper 120 is disposed on a port of each insertion hole 110, and when one end of the movable base 200 is inserted into the insertion hole 110, the latch 210 is inserted between two adjacent stoppers 120. This arrangement facilitates the positioning of the respective latches 210 in alignment with the respective guide grooves 130 during operation.

Referring to fig. 4, 5 to 8, a stop strip 140 axially extends along one end of each stopper 120 in the forward direction. The arrangement of the stop strip 140 not only enables the fixture block 210 to rotate in the forward direction when being separated from the stop block 120 in the circumferential direction, but also prevents a user from rotating blindly when the user is installing because the stop strip 140 on the stop block 120 at the reverse position is arranged in the reverse position to stop; meanwhile, the stopper bar 140 is further configured to limit a forward rotation stroke of the latch 210 when the movable base 200 carries the latch 210 to rotate forward, so as to prevent the latch 210 from rotating forward without limitation.

In one embodiment, referring to fig. 2, 3 and 5, the anti-slip mechanism 1000 further includes a mounting plate 700, a first elastic member 400 and a limiting plate 500. The mounting plate 700 is fixedly mounted on the first structural member 2000, a mounting hole 710 is formed on the mounting plate 700, and the movable seat 200 is arranged to penetrate through the mounting hole 710; the first elastic element 400 is abutted between one side of the mounting plate 700 and the movable seat 200; the limiting plate 500 is installed on the movable seat 200 and stopped on the other side of the installation plate 700.

When the device is installed, the first elastic member 400 is firstly sleeved on the movable base 200; then, the movable seat 200 axially penetrates through the mounting hole 710, so that the two opposite ends of the movable seat 200 extend out of the mounting hole 710, and the first elastic element 400 abuts between one side of the mounting plate 700 and the other end of the movable seat 200; finally, the position-limiting plate 500 is installed at a position close to one end of the movable seat 200. In the initial state, the first elastic member 400 is in a stretched state, and the limiting plate 500 is stopped on the other side of the mounting plate 700, so that the movable seat 200 is movably mounted on the mounting plate 700 through the first elastic member 400 and the limiting plate 500.

When the movable seat 200 and the fixed seat 100 are installed, the fixed seat 100 is first disposed at the other side of the installation plate 700, and the other end of the movable seat 200 is axially pressed so that one end of the movable seat 200 is inserted into the insertion hole 110 of the fixed seat 100. At this time, since the position of the mounting plate 700 is fixed, when the movable base 200 moves axially close to the fixed base 100, the first elastic member 400 is compressed; when the movable seat 200 is unlocked and clamped with the fixed seat 100, the movable seat 200 is reset under the elastic action of the first elastic member 400 until the limiting plate 500 stops at the other side of the mounting plate 700.

In addition, the mounting plate 700 may be a part of the second structural member 3000, that is, the movable seat 200 is directly movably mounted on the second structural member 3000 through the first elastic member 400 and the limiting plate 500; of course, the mounting plate 700 may be fixedly mounted on the first structural member 2000, and the movable seat 200 may be movably mounted on the mounting plate 700 through the first elastic member 400 and the limiting plate 500, so as to movably mount the movable seat 200 on the second structural member 3000.

In one embodiment, referring to fig. 9 and 10, a slot 220 extending along a circumferential direction is formed on an outer wall of the movable base 200; the limiting plate 500 is annular, the limiting plate 500 has a fracture 510 along the circumferential direction, and a plurality of protrusions 520 distributed along the circumferential direction are formed on the inner wall of the limiting plate 500; each protrusion 520 can be engaged with the corresponding slot 220. The fracture 510 is arranged to make the limiting plate 500 elastic, and when the limiting plate is installed, the fracture 510 of the limiting plate 500 can be expanded to sleeve the limiting plate 500 at the position of the slot 220, and the protrusions 520 of the limiting plate 500 are respectively clamped in the slot 220, so that the limiting plate 500 is installed in the movable seat 200; when the fracture needs to be disassembled, the limiting plate 500 is only required to be expanded along the fracture 510 and the limiting plate 500 is taken down from the clamping groove 220, and the operation is simple.

In one embodiment, referring to fig. 3 and 5, the locking member 300 is slidably disposed on the movable base 200 along the axial direction of the movable base 200; the locking member 300 is located between two adjacent latches 210 along the circumferential direction of the movable seat 200; the locking member 300 can be driven in the axial direction of the movable seat 200 to be inserted into the guide groove 130, and the locking member 300 can be driven in the axial direction of the movable seat 200 to be withdrawn from the adjacent guide groove 130.

Specifically, when the movable seat 200 is inserted into the fixed seat 100, firstly, the latch 210 is inserted into the guide groove 130, after the latch 210 is inserted to a predetermined depth, and when the latch 210 is driven to rotate and stopped at the inner side of the stopper 120, the locking member 300 is just located on the axial outer end surface of the guide groove 130, at this time, the locking member 300 is driven in the axial direction to enable the locking member 300 to be inserted into the guide groove 130 in the axial direction, so that the locking member 300 is limited in the fixed seat 100, and the locking member 300 is installed on the movable seat 200, so that the movable seat 200 cannot rotate relative to the fixed seat 100, and the movable seat 200 is prevented from being separated from the fixed seat 100. When the movable seat 200 needs to be rotated, the locking member 300 is driven to axially withdraw from the guide groove 130, without the limitation of the stopper 120, so that the movable seat 200 can be rotated, and the movable seat 200 can be withdrawn from the fixed seat 100.

In this embodiment, the locking member 300 is inserted into the guide groove 130 between two adjacent stoppers 120, so as to realize the insertion between the locking member 300 and the fixing base 100, that is, the stoppers 120 that realize the rotational engagement between the movable base 200 and the fixing base 100 are used to realize the insertion between the locking member 300 and the fixing base 100, so that no additional slot is required to be formed on the fixing base 100 to form the insertion with the locking member 300; meanwhile, only when the movable base 200 rotates by a first preset angle, the latch 210 is firmly clamped with the stopper 120, and at this time, the locking member 300 is required to be inserted into the fixed base 100, and at this time, the latch 210 is just separated from the guide groove 130 between the two stoppers 120; the guide groove 130 is favorable for being inserted into the locking member 300, so that the rotation of the movable seat 200 and the insertion of the locking member 300 can be linked, and the operation of an operator is facilitated.

Wherein actuation of the locking member 300 may be manual, external structural actuation, or internal structural actuation.

In one embodiment, referring to fig. 3 and fig. 5, the anti-falling off mechanism 1000 further includes a second elastic member 600, and the second elastic member 600 is abutted between the locking member 300 and the movable base 200. When the movable holder 200 is axially inserted into the insertion hole 110, each latch 210 is inserted into each guide groove 130, the locking member 300 circumferentially located between adjacent latches 210 is stopped on the end surface of the fixed holder 100 facing the mounting plate 700, and at this time, the second elastic member 600 elastically compresses and accumulates elastic force; after the movable seat 200 rotates by a first preset angle, the latch 210 is stopped on the stopper 120, the locking member 300 is just opposite to one of the guide slots 130 in the axial direction, and at this time, the second elastic member 600 elastically pushes the locking member 300 to enable the locking member 300 to be inserted into the guide slot 130, that is, the movable seat 200 can be rotationally locked without manual operation. In this embodiment, the second elastic member 600 is arranged, so that the locking member 300 can be automatically inserted into the guide groove 130 under the elastic pressure of the second elastic member 600 after the movable base 200 is rotated to the position, and the operation is simple and labor-saving; and when it is required to take out the locking member 300 from the guide groove 130, it is only necessary to manually push the locking member 300 in the axial direction.

Among them, the second elastic member 600 is preferably a compression spring. It is understood that, in other embodiments of the present application, the second elastic element 600 may also be an elastic sheet.
