It should be noted that, clasp 100 is not limited to be applied to LED display, also can apply on other devices, such as, between the casing of equipment box and case lid.
Specifically in the present embodiment, hasp pedestal 102 is roughly the U-shaped structure of strip, and is extended with base in U-shaped structural base, for being connected with the support of LED display.Hasp accepting groove is the thin-and-long groove extended along the length direction of hasp pedestal 102.
Turning arm 110 comprises rotating shaft 112 and is located at the rotating disk 114 of rotating shaft one end, and rotating disk 114 is arranged at the sidewall of hasp accepting groove by rotating shaft 112.Concrete rotating disk 114 is circular in the present embodiment, and the center of circle of rotating disk 114 is rotatably connected by the sidewall of rotating shaft 112 with the hasp accepting groove of hasp pedestal 102.The center of rotation of turning arm 110 and the rotating shaft of rotating disk 114.The periphery of rotating disk 114 is provided with flange.
It should be noted that, turning arm 110 is not limited by rotating shaft 112 and is rotatably connected with hasp pedestal 102, and hasp 120 is not limited to be rotatably connected with turning arm 110, also can adopt other modes, such as, be coupled together rotationally by hinge arrangement.
The relative both sides of hasp accepting groove are provided with guide rail 140 along the radial direction of turning arm 110, and turning arm 110 is arranged in hasp accepting groove by guide rail 140.Specifically in the present embodiment, guide rail 140 hollow out is arranged at the sidewall that general shape is the length direction of the hasp pedestal 102 of U-shaped structure, and the turning arm 110 be arranged on hasp pedestal 102 by guide rail 140 can be moved around along guide rail 140.
The rotating shaft 112 of turning arm 110 successively through guide rail 140, hasp 120 connecting portion and be fixed on the sidewall of hasp accepting groove by screw.
Hasp 120 comprises holding section and snaps, and holding section is connected with snaps, holding section for hook, snaps is hollow cylinder, holding section and snaps one-body molded, wherein, holding section is connected with the axial cylinder of snaps.
Clasp 100 also comprises stroke screw shaft member 130, and one end that its one end is connected with hasp pedestal 102 with turning arm 110 is fixedly connected with, and its other end is arranged at hasp pedestal 102 sidewall; Stroke screw shaft member 130 is arranged along the direction of guide rail 140.
Stroke screw shaft member 130 comprises thread spindle 132 and is located at the stroke rotation disc 134 of thread spindle 132 one end, and stroke rotation disc 134 is arranged at the sidewall of hasp accepting groove by thread spindle 132, and wherein, thread spindle 132 follows the rotation of stroke rotation disc 134.
Stroke screw shaft member 130 comprises thread spindle 132 and stroke rotation disc 134, one end of thread spindle 132 is provided with guiding connecting portion, guiding connecting portion is connected with the rotating shaft 112 of turning arm 110, thread spindle 132 moves for the radial direction drive turning arm 110 along turning arm 110, the moving direction of thread spindle 132 and the axially not coaxial of turning arm 110.
The end of thread of thread spindle 132, through the sidewall of hasp accepting groove, is fixed by the sidewall of nut and hasp accepting groove; Wherein, stroke rotation disc 134 threadingly tightens up direction and rotarily drives thread spindle 132 threadingly axially the moving away from the hasp 120 be connected with thread spindle 132 and turning arm 110 of axle 132.
Turning arm 110 is rotated in direction towards fixed axis 204, the hasp 120 be connected with turning arm 110 is driven to move towards the direction of fixed axis 204, after the holding section of hasp 120 and fixed axis 204 are connected, hasp structure 10 and hasp fixed structure 20 complete preliminary connection, after generally holding section is connected with fixed axis 204, holding section can not at every turn just all completely and fixed axis 204 be connected, therefore, adjustment stroke screw shaft member 130 is needed to allow holding section and fixed axis 204 closely cooperate.When connection gap between holding section and fixed axis 204 is larger, then adjustment stroke screw shaft member 130 is needed to drive hasp 120 to move towards the direction away from fixed axis 120.When holding section can not be connected with fixed axis 204, when namely hasp 120 is far away apart from fixed axis 204, then adjustment stroke screw shaft member 130 is needed to drive hasp 120 to move towards the direction of fixed axis 120.
Hasp pedestal 102 is corresponding with the contact-making surface of fixed pedestal 202 is provided with reference column 150 and location hole (not shown), wherein, hasp pedestal 102 is arranged reference column 150, fixed pedestal 202 arranges location hole.
In general, hasp pedestal 102 and fixed pedestal 202 can be respectively installed on two casings to be connected, therefore, before hasp 120 is connected with fixed axis 204, both hasp pedestal 102 and fixed pedestal 204 is needed to aim at, and casing build generally to be connected is comparatively large, accurate object of reference cannot be adopted in the aligning process thus complete aligning fast and accurately.Therefore, after on hasp pedestal 102 and fixed pedestal 204, correspondence arranges reference column 150 and location hole, as long as reference column 150 and location hole are connected, aiming at, for the connection between hasp 120 and fixed axis 204 is prepared of hasp pedestal 102 and fixed pedestal 202 can be completed.
Above-mentioned clasp 100 by rotating turning arm 110, the center of rotation of turning arm 110 and the center of rotation of hasp 120 coaxial, and drive hasp 120 to rotate, make the holding section of hasp 120 engage with fixed axis 204 and be separated, thus can connect rapidly.
The above embodiment only have expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
