Description

Technical Field

[0001] The present invention relates to the technical field of maintenance locks for LED display screens, and in particular to a module quick maintenance lock for an LED display screen. Background Art

[0002] The difficulty in maintaining LED display screens has become a pain point for many users. For users who use embedded or wall-mounted installations, inspection and maintenance work has become very difficult.

[0003] LED display maintenance methods are mainly divided into front maintenance and rear maintenance. The biggest advantage of front maintenance is that it saves space. For indoor or inlaid or wall-mounted structures, space is extremely valuable, so there is not much room left for maintenance access. Therefore, front maintenance can greatly reduce the overall thickness of the LED display structure, which can not only integrate well with the surrounding architectural environment, but also save space while ensuring the effect. However, this structure has very high requirements for the equipment's heat dissipation function. The biggest advantage of rear maintenance is that it is slightly less expensive, suitable for roof-mounted and column-mounted installation scenarios, and convenient and efficient inspection and maintenance. For large LED displays installed on the exterior walls of buildings, maintenance access must be designed so that maintenance personnel can perform maintenance and inspections from the back of the screen.

[0004] The current LED module maintenance lock can only be maintained from the front or from the back, but not both. Therefore, the application range is limited, and the unlocking and locking operations are complicated, making maintenance inconvenient. Summary of the Invention

[0005] In view of the above-mentioned deficiencies in the prior art, the present invention provides a module quick maintenance lock for an LED display screen, which solves the technical problem of achieving front maintenance and rear maintenance through a quick maintenance lock and improving the convenience of use by adopting a rotary opening and closing lock.

[0006] The technical solution adopted by the present invention to solve the above problems is:

[0007] The present invention provides a module quick maintenance lock for an LED display screen, comprising a locking rod, a locking tongue, a spring, a bracket, and a handle, wherein the locking rod comprises a lower rod, a middle rod, and an upper rod with successively decreasing diameters, the top side of the lower rod being provided with a first D-shaped missing block, the side of the upper rod being provided with a second D-shaped missing block, and the top of the locking rod being provided with a first screw hole; one end of the locking tongue being provided with a first D-shaped hole sleeved on the top end of the lower rod, and the other end of the locking tongue being provided with a semicircular locking hole; the spring being located between the locking tongue and the bracket and sleeved outside the locking rod; a circular hole being provided in the middle of the bracket for passing through the upper rod; the handle comprising a middle connecting column and rotating handles on both sides, the lower end of the middle connecting column being provided with a second D-shaped hole matching the top of the upper rod, and the upper end of the middle connecting column being provided with a second screw hole; the screw passing through the second screw hole and the first screw hole from top to bottom.

[0008] Furthermore, the height of the first D-shaped missing block is smaller than the height of the second D-shaped missing block.

[0009] Furthermore, both sides of the semicircular lock hole of the lock tongue are arc-shaped lock tongue parts.

[0010] Furthermore, the bracket is in a "J"-shaped structure, including a top plate, two side walls and two mounting wings.

[0011] The circular hole is provided in the middle of the top plate, and a front baffle and a rear baffle are provided at the front and rear ends of the circular hole of the top plate.

[0012] Furthermore, arc-shaped gripping portions are provided on the edges of the rotating handles on both sides of the handle, and an unlocking mark and a locking mark are provided on both sides of the top surface of the handle.

[0013] The beneficial effect of the module quick maintenance lock of the LED display screen of the present invention is that: after the quick maintenance lock is assembled, when the module is maintained from the front, the lock rod can be pressed and rotated to unlock, and the lock can be locked by pressing the lock rod, rotating it back, and then releasing and pressing; when maintaining the module from the rear, the quick lock handle can be manually lifted up and rotated to unlock, and the handle can be lifted up, rotated back, and then released to lock, thereby achieving the technical effect of both front maintenance and rear maintenance, and improving the convenience of maintenance lock operation by rotating the lock to open and close.
