Being applied to the hasp lock on LED display at present is to clasp snap close by U-shaped pull bar mostly; its tightening force is little; it is difficult to locking; intensity is relatively low, is easily broken off, and volume is bigger; structure is complicated; inconvenience is installed, and can not the most quickly open and close, and causes power supply lid that power supply module can not realize protective effect well.
Summary of the invention
The defect existed for prior art; it is an object of the invention to provide a kind of LED display arc hasp lock; it is made to solve existing like product hasp lock tightening force little; being difficult to locking, intensity is relatively low, is easily broken off; volume is bigger; structure is complicated, and inconvenience is installed, and can not the most quickly open and close the problem causing power supply lid power supply module can not be realized protection very well.
For achieving the above object, present invention employs following technical proposals:
A kind of LED display arc hasp lock, this arc hasp lock includes arc shaped rotary switch block, the first bearing pin, the second bearing pin, lower fixed block and upper fixed block, described upper fixed block is arranged on power pack lid, described lower fixed block is arranged on casing, described arc shaped rotary switch block is hinged on lower fixed block movably by the first bearing pin, it is hinged with the second bearing pin on described upper fixed block, arc shaped rotary switch block is when the first bearing pin rotates, and the arcuate recess sections of arc shaped rotary switch block fastens with the second bearing pin on upper fixed block and makes power pack cover locking on casing.
As the improvement of such scheme, the first described bearing pin being provided with torsion spring, described torsion spring set is located on the first bearing pin, and when making arc hasp lock open, arc shaped rotary switch block has resilience force.
As the improvement of such scheme, the second described bearing pin being arranged with sleeve, described sleeve is set on the second bearing pin movably, enables the arcuate recess sections of arc shaped rotary switch block to fasten lock with sleeve smoothly.
The beneficial effects of the present invention is: provide a kind of LED display arc hasp lock, overcome hasp lock tightening force on existing LED display little, it is difficult to locking, intensity is relatively low, is easily broken off, and volume is bigger, structure is complicated, inconvenience is installed, and the defect that can not the most quickly open and close, have simple in construction, compact, be easily installed, the advantage such as coupling mechanism force is big.
