Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of snap close reducing to rub between mounting blocks and support.
For achieving the above object, the utility model adopts following technical scheme, comprise main panel, main panel both sides are fixedly connected with mounting blocks, and mounting blocks is provided with installing hole, and main panel is provided with through hole, through hole side is connected with cantilever plate, be provided with ball grooves outside described mounting blocks, be movably equipped with ball in ball grooves, a described ball part protrudes mounting blocks surface.
Preferably, ball grooves is annular raceway, and described raceway and installing hole are coaxially arranged, and described ball is movably set in and is positioned at raceway.
Preferably, the mounting groove that ball grooves is independently arranged by several is formed, and described each mounting groove opening part is provided with clasps portion for what clasp ball, and described ball is rotatably arranged in mounting groove and a part is protruded from mounting groove opening part.
Preferably, cantilever plate is connected with buffer bar near through hole side.
Preferably, lubricating grease is filled with in mounting groove.
The utility model hinge structure is compared to be had: be provided with ball grooves outside mounting blocks, be movably equipped with ball in ball grooves, and a described ball part protrudes mounting blocks surface.When lock dog will rotate, ball rolls, and is to roll to be connected between ball with support, and which reduce the frictional force between mounting blocks and support, mounting blocks can not block when rotating.

Embodiment
Referring to figs. 1 through Figure 11, the utility model snap close embodiment is described further.
A kind of snap close 3, comprise main panel, main panel both sides are fixedly connected with mounting blocks 31, mounting blocks 31 is provided with installing hole 313, main panel is provided with through hole 314, and through hole 314 side is connected with cantilever plate 315, is provided with ball grooves outside described mounting blocks 31, be movably equipped with ball 3111 in ball grooves, described ball 3111 part protrudes mounting blocks 31 surface.Comprise dropout process and detain process again during transmission mechanism work.During dropout process, the power of drop-down end points bracket is directly passed to lever 2, and this will make to trip instantaneously between snap close 3 and cramp 1, and under master draws the effect of spring 8, drive movable feeler lever 7, moving contact 71 separates with fixed contact 72 simultaneously.When triping, lever 2 near snap close 3 one end upwards, snap close 39 rotates around the shaft, and when lock dog will rotate, ball 3111 rolls, roll to be connected between ball 3111 with support 10, which reduce the frictional force between mounting blocks 31 and support 10, mounting blocks 31 can not block when rotating, due to main effect of drawing spring 8, pull connecting rod 4 and lower link 4, drive movable feeler lever 7 and cramp 1 to move upward simultaneously.When detaining process again, operating grip 6 left, drives lever 2 and master to draw spring 8, thus snap close 3 is locked with cramp 1 mutually with lever 2 downwards, and upper connecting rod 4 and lower link 4, drive movable feeler lever 7 downward downwards, and moving contact 71 and fixed contact 72 close.During pinning, snap close 3, lever 2 is near snap close 3 one end, cramp 1 downwards simultaneously, snap close 3 props up lever 2, cantilever plate 315 on snap close 3 props up cramp 1, cantilever plate 315 is connected with buffer bar 3151 near through hole 314 side, because cantilever plate 315 and cramp 1 are all hard, interaction force can be produced between the two when propping up cramp 1, permanent use can cause cramp 1 or cantilever plate 315 to damage, after having had buffer bar 3151, cramp 1 is buckled in when depressing in buffer bar 3151, reduce impulsive force, can increase the service life, buffer bar 3151 is elastomeric material, rubber can be used, rubber is bonding by seccotine with cantilever plate 315.Ball grooves is annular raceway 311, and described raceway 311 is coaxially arranged with installing hole 313, and described ball 3111 is movably set in and is positioned at raceway 311.
Form as the mounting groove 312 that preferably another technical scheme ball grooves is independently arranged by several, described each mounting groove 312 opening part is provided with the portion that clasps 3112 for clasping ball, and described ball 3111 is rotatably arranged in mounting groove 312 and a part is protruded from mounting groove 312 opening part.The described ball 3111 being greater than 1/2nd, in ball grooves, can be that the ball 3111 of 2/3rds or 3/5ths is in ball grooves.Such ball 3111 arbitrarily can rotate in ball grooves, there will not be stuck phenomenon, and the portion that clasps is for embracing ball 3111, and ball 3111 can not be dropped out, and second way mounting groove 311 can be arranged on optional position outside mounting blocks 31.Lubricating grease is filled with in mounting groove 312, can lubricate, prevent ball 3111 stuck in ball grooves.Described ball 3111 is made for hard material, can be little steel ball or little copper pearl.
