Embodiment
In order that technical problem solved by the invention, technical scheme and beneficial effect are more clearly understood, below in conjunction with
Drawings and Examples, the present invention is described in further detail.It should be appreciated that specific embodiment described herein is only
To explain the present invention, it is not intended to limit the present invention.
As shown in figure 1, one embodiment of the invention provide arc lock, including the first rotating mechanism 1, the second rotating mechanism 2,
For connecting the catch assembly 3 of the first rotating mechanism 1 and the second rotating mechanism 2 and being arranged on the bottom of the first rotating mechanism 1
Roll adjustment component 4.As shown in Fig. 2 roll adjustment component 4 includes regulation handle 401 and threaded rod 402, the bottom of the first rotating mechanism 1 is set
There is screwed hole 104, threaded rod 402 is threaded in screwed hole 104, and regulation handle 401 is fixedly connected on the outer of threaded rod 402
End, the inner ecto-entad of threaded rod 402 pass through screwed hole 104.
It should be understood that arc lock provided in an embodiment of the present invention, roll adjustment component 4 is set in the bottom of the first rotating mechanism 1,
It includes regulation handle 401 and threaded rod 402, makes the axle in the threadingly hole 104 of threaded rod 402 by rotating regulation handle 401
To rotation, to cause the LED display unit being fixed between the first rotating mechanism 1 and the second rotating mechanism 2 to carry out gap tune
Section, can effectively it overcome because piece, influence LED display occurs in LED display caused by LED display unit machining error
The adverse effect such as display effect.In addition, arc lock provided in an embodiment of the present invention need not unclamp catch assembly 3 and can adjust
The piece of LED display, regulative mode is convenient and swift, and its is simple in construction.
As shown in figure 1, catch assembly 3 includes hasp handle 301, tie rod 302, snap lock part 303 and button
304, one end of tie rod 302 is rotatablely connected by one first rotary shaft 7 with hasp handle 301, the other end of tie rod 302 with
Snap lock part 303 is fixedly connected, and hasp handle 301 is rotatablely connected by one second rotary shaft 8 and the second rotating mechanism 2；The
One rotating mechanism 1 is provided with keeper 1011, is provided with the opposite side of the second rotating mechanism 2 on keeper 1011 and is taken for locking
Detain the stopper slot 1012 of locking piece 303.
Button 304 can toggle between lock position and unlocked position.Specifically, in the lock position of button 304,
The locking hasp handle 301 of button 304, to prevent hasp handle 301 from being manipulated；In the unlocked position of button 304, button
304 release the locking to hasp handle 301, to enable hasp handle 301 to be manipulated；In the unlocked position of button 304, manipulate
Hasp handle 301 can be such that tie rod 302 is rotated around the first rotary shaft 7 relative to hasp handle 301, to cause snap lock part 303
Depart from stopper slot 1012.
When snap lock part 303 is locked in the stopper slot 1012 of keeper 1011, and tie rod 302 passes through first
When rotary shaft 7 tenses, button 304 is switched into lock position, the one end of button 304 is ridden against on hasp handle 301, so as to
Locking is carried out to hasp handle 301, the position of hasp handle 301 is fixed and not rotatable, to realize the He of the first rotating mechanism 1
It is fixedly connected between second rotating mechanism 2；When button 304 switches to unlocked position, button 304 will be disengaged from hasp handle 301,
Hasp handle 301 can be rotated, and when user is rotated up hasp handle 301 along the second rotary shaft 8, tie rod 302 will be along
One rotary shaft 7 rotates relative to hasp handle 301, snap lock part 303 is departed from the locking of the stopper slot 1012 of keeper 1011,
First rotating mechanism 1 and the second rotating mechanism 2 separate.
It should be understood that by setting catch assembly 3 between the first rotating mechanism 1 and the second rotating mechanism 2, can be effective
The dislocation between two LED display units is corrected, realizes being fixedly connected between the two.
