A lock with constraint chute, led box and led display

Abstract

The invention provides a lock buckle with a restraining chute, which can be used for the tight splicing of the box body, including a lock hook assembly and a hook pin assembly. The lock hook of the four-bar linkage mechanism closely connects the lock hook assembly and the hook pin assembly, and is characterized in that: the lock hook shaft is fixed and the lock hook is provided with a lock hook chute; the lock hook cover and the lock hook seat are respectively provided with relative constraints The two ends of the chute and the locking hook shaft are respectively installed in the constraint chute and can move along the chute. The fixed shaft of the lock hook and the restraint chute make the movement of the atypical four-bar linkage mechanism adopted by the lock flexible and reliable, and it is not easy to get stuck; the lock hook has elastic stretching ability, which can eliminate the connection gap caused by processing errors; simple operation, one action The lock and latch can be completed, and it has self-locking ability. The LED display screen formed by connecting the LED cabinets with locks according to the present invention can bear a large weight of the LED cabinets, and the splicing is tight and precise. The LED screen cabinets can be connected and loosened with one action, and the operation is convenient.

Description

technical field [0001] The invention relates to machinery and structural devices, in particular to a lock with a restraining chute, an LED box and an LED display. Background technique [0002] Many devices composed of multiple cabinets need to solve the problem of close connection of the cabinets. For example, LED display screens are spliced ​​by LED cabinets equipped with LED display components, and various locks are often used for the connection of the cabinets. For example, the Chinese patent document CN102829039A "A Locking Connecting Device, LED Screen Cabinet and LED Display" discloses a lock. After pinning, press the handle to stretch the lock hook, so that the lock hook seat and the pin seat can be tightly connected, and at the same time, the handle makes the gear drive the latch to insert into the fixed pin hole on the pin seat. The disadvantage of the lock is that the handle affects the miniaturization of the lock, and the lock occupies the area of ​​the back cove...

AI Technical Summary

Problems solved by technology

Because the lock hook of the lock has the requirement of moving back and tightening self-locking, that is, the lock hook shaft is not fixed and must move in the lock hook chute, so its mechanism movement is not a typical four-bar linkage movement, and it is easy to get stuck; although This document uses a spring to push the lock hook shaft against the front end of the lock hook chute when it is not moved back and tightened, in an attempt to alleviate the stagnation, but the processing of the spring and the installation on the miniaturized lock buckle are relatively difficult, resulting in a complicated lock buckle structure. Disadvantages such as difficult processing and installation, high failure rate, and high cost
