See also Fig. 1, the clasp 100 of preferred embodiments of the present invention comprises: hasp structure 10 and hasp fixed structure 20.
Hasp fixed structure 20 comprises: fixed pedestal 202 and fixed axis 204.Fixed pedestal 202 is provided with the fixed axis accepting groove, is used to accommodate fixed axis.Fixed axis 204 cooperates with the holding section and hasp 120 removably is fixedly connected with fixed axis 204.Wherein, The free end of turning arm 110 rotates towards the direction away from fixed pedestal 202; Hasp 120 is followed turning arm 110 and is rotated, and an end at place, the holding section of hasp 120 also rotates towards the direction away from fixed axis 204, makes the holding section perk and separates with fixed axis 204.
Need to prove that clasp 100 is not limited to be applied to LED display, also can use on other devices, for example, between the casing and case lid of equipment box.
Specifically in this execution mode, hasp pedestal 102 is roughly the U-shaped structure of strip, and is extended with base in the U-shaped structural base, is used for being connected with the support of LED display.The hasp accepting groove is the thin-and-long groove along the length direction extension of hasp pedestal 102.
Turning arm 110 comprises rotating shaft 112 and is located at the rotating disk 114 of rotating shaft one end that rotating disk 114 is arranged at the sidewall of hasp accepting groove through rotating shaft 112.Specifically in this execution mode, rotating disk 114 is circular, and the center of circle of rotating disk 114 is rotatably connected through the sidewall of rotating shaft 112 with the hasp accepting groove of hasp pedestal 102.The center of rotation of turning arm 110 is the rotating shaft of rotating disk 114.The periphery of rotating disk 114 is provided with flange.
Need to prove that turning arm 110 is not limited to be rotatably connected through rotating shaft 112 and hasp pedestal 102, hasp 120 is not limited to be rotatably connected with turning arm 110, also can adopt other modes, for example, couples together rotationally through hinge arrangement.
The relative both sides of hasp accepting groove radially are provided with guide rail 140 along turning arm 110, and turning arm 110 is arranged in the hasp accepting groove through guide rail 140.Specifically in the present embodiment, guide rail 140 hollow outs are arranged at the sidewall of length direction that general shape is the hasp pedestal 102 of U-shaped structure, and the turning arm 110 that is arranged on the hasp pedestal 102 through guide rail 140 can move around along guide rail 140.
The rotating shaft 112 of turning arm 110 is passed the connecting portion of guide rail 140, hasp 120 successively and is passed through screw in the sidewall of hasp accepting groove.
Clasp 100 also comprises stroke screw shaft spare 130, and the one of which end is fixedly connected with the end that turning arm 110 links to each other with hasp pedestal 102, and its other end is arranged at hasp pedestal 102 sidewalls; Stroke screw shaft spare 130 is along the direction setting of guide rail 140.
Stroke screw shaft spare 130 comprises thread spindle 132 and is located at the stroke rotation disc 134 of thread spindle 132 1 ends, and stroke rotation disc 134 is arranged at the sidewall of hasp accepting groove through thread spindle 132, and wherein, thread spindle 132 is followed the rotation of stroke rotation disc 134.
Stroke screw shaft spare 130 comprises thread spindle 132 and stroke rotation disc 134; One end of thread spindle 132 is provided with the guiding connecting portion; The guiding connecting portion is connected with the rotating shaft 112 of turning arm 110; Thread spindle 132 is used for moving along the radially driven rotary arm 110 of turning arm 110, the moving direction of thread spindle 132 and turning arm 110 axially not coaxial.
The end of thread of thread spindle 132 passes the sidewall of hasp accepting groove, fixes through the sidewall of nut and hasp accepting groove; Wherein, stroke rotation disc 134 tightens up the direction rotation along screw thread and drives thread spindle 132 axially moving away from hasp 120 that is connected with thread spindle 132 and turning arm 110 along thread spindle 132.
Direction towards fixed axis 204 is rotated turning arm 110; Driving the hasp 120 that is connected with turning arm 110 moves 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 accomplished and tentatively is connected, owing to holding section generally speaking with after fixed axis 204 is connected, the holding section can not be all complete just at every turn and fixed axis 204 be connected; Therefore, need adjustment stroke screw shaft spare 130 to let holding section and fixed axis 204 closely cooperate.When being connected the slit when big between holding section and the fixed axis 204, then need adjustment stroke screw shaft spare 130 to drive hasps 120 towards direction motion away from fixed axis 120.When the holding section can not be connected with fixed axis 204, when promptly hasp 120 fixed distance axles 204 are far away, then need adjustment stroke screw shaft spare 130 to drive the direction motion of hasp 120 towards fixed axis 120.
Corresponding reference column 150 and the location hole (figure does not show) of being provided with of the contact-making surface of hasp pedestal 102 and fixed pedestal 202 wherein, is provided with reference column 150 on the hasp pedestal 102, on the fixed pedestal 202 location hole is set.
In general; Hasp pedestal 102 can be respectively installed on two casings to be connected with fixed pedestal 202; Therefore, with hasp 120 with before fixed axis 204 is connected, need both aim at hasp pedestal 102 and fixed pedestal 204; And casing build general to be connected is bigger, thereby in alignment procedures, can't adopt accurate object of reference to accomplish aligning fast and accurately.Therefore; After correspondence is provided with reference column 150 and location hole on hasp pedestal 102 and the fixed pedestal 204; As long as reference column 150 and location hole are connected, can accomplish aiming at of hasp pedestal 102 and fixed pedestal 202, for being connected between hasp 120 and the fixed axis 204 prepares.
Above-mentioned clasp 100 is through rotating turning arm 110, and the center of rotation of the center of rotation of turning arm 110 and hasp 120 is coaxial, rotates and drive hasp 120, the holding section of hasp 120 is engaged with fixed axis 204 and separates, thereby can connect apace.
The above embodiment has only expressed several kinds of execution modes of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the present invention's design, 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 accompanying claims.
