Specific embodiment

In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only used to explain The utility model is not used to limit the utility model.

Please refer to Fig. 1-9, a kind of Novel lock catch 100, including buckle chassis 30, fastener 20, axis 40,10 and of snap lock Spring 50；Buckle chassis 30 is mounted on metal plate 102, and fastener 20 is connect by axis 40 with buckle chassis 30, snap lock 10 It is mounted in rack 101, snap lock 10 is equipped with a up big and down small card hole 13；Fastener 20 is cross section in I-shaped Structure, fastener 20 include the first card convex 23, connecting rod 22 and the second card convex 21, and connecting rod 22 is located at the first card convex 23 and second It is integrally formed between card convex 21, card hole 13 is sticked by the first card convex 23, so that the card of snap lock 10 and in the first card convex 23 and the Between two card convexs 21, so that metal plate 102 is detachably connected with rack 101.

Fig. 1-9 is please referred to, snap lock 10 is equipped with card hole 13, and the upper end of card hole 13 is round hole 131, round hole 131 Lower end offers the U-shaped hole being connected with round hole 131 132, and U-shaped hole 132 and round hole 131 are joined together to form card Hole 13；Card hole 13 is also possible to small top and big bottom other shapes, and what the present embodiment was recorded is one form of them, not For limiting the utility model.The big round hole 131 in upper end is slightly larger than the first card convex 23, and the first card convex 23 sticks into round hole 131 It is interior, it then moves down, is locked in U-shaped hole 132, diameter of the diameter less than the second card convex 21 of the first card convex 23, round hole 131 diameter is again smaller than the diameter of the second card convex 21, and therefore, when the first card convex 23 sticks into round hole 131, the second card convex 23 is not It can be across round hole 131；So that snap lock 10 is blocked by card hole 13 and the connection between the first card convex 23 and the second card convex 21 On bar 22, all day moves down, and connecting rod 22 is blocked and is fastened between U-shaped hole 132, completes the dress of metal plate 102 and rack 101 Match.Snap lock 10 is equipped with the first threaded hole 11, and the quantity of the first threaded hole 11 is at least 2, and the first threaded hole 11 will be for that will block Padlock 10 is fixed in rack 101.

Fig. 1-9, fastener 20, including the first card convex 23, connecting rod 22, the second card convex 21 and first through hole 24 are please referred to, Connecting rod 22 is integrally formed between the first card convex 23 and the second card convex 21, and first through hole is equipped at the axle center of fastener 20 24, axis 40 pass through first through hole 24 so that fastener 20 can on axis 40 free back and forth movement.

Fig. 1-8 is please referred to, chassis 30, including pedestal 31, limited block 32, the second threaded hole 33 and third threaded hole are buckled 34；Pedestal 31 is an integral molding structure with limited block 32, and the cross section on buckle chassis 30 is in the structure of T font, buckles chassis 30 Axle center at be equipped with the second threaded hole 33 for being coupled with axis 40；Buckle chassis 30 is mounted on metal plate by third threaded hole 34 On gold 102, the quantity of third threaded hole 34 is at least 2.

Fig. 1-9 is please referred to, one end of axis 40 has screw thread, and axis 40 is placed through in fastener 20, the screw thread of axis 40 It holds and is threadedly coupled with the second threaded hole 33 on buckle chassis 40；Axis 40 sequentially passes through fastener 20 and one and is used for the bullet of damping Spring 50, spring 50 are connected between fastener 20 and buckle chassis 40.Matched by adjusting axis 40 with the screw thread for buckling chassis 30 Depth is closed, the distance between fastener 20 and buckle base 30 are controlled, to reach the outer surface of leveling metal plate 102, makes each metal plate The flush with outer surface of gold 102.In addition, because machine tool starts and can generate certain vibration when working, in addition damping spring 50, it can effectively slow down the shell metal plate 102 generated because of machine vibration and vibrate.It is adopted in the preferred embodiment of the utility model The spring 50 being tapered in, the opening on 50 both sides of spring is different big, and for big mouth close to buckle chassis 30, small mouth is close Fastener 20, such gradual change type design, enables spring 50 to bear bigger pressure, crushing resistance is stronger.

Please refer to Fig. 1-9, the utility model can install quickly and easily, dismantle metal plate 102 in rack 101, this is practical Novel Novel lock catch 100 is also applied for other occasions for needing often to mount and dismount；In fastener 20 and buckle base 30 Between the spring 50 that is added can effective damping, reduce the friction between fastener 20 and buckle base 30, prolong the service life.

Fig. 1-9 is please referred to, a kind of Novel lock catch 100 provided by the utility model can change buckle according to the actual situation The installation direction of lock 10 and position, buckle chassis 30, axis 40, spring 50 and the fastener 20 being mounted on metal plate 102 cooperate The change of snap lock 10 allows lock to pay mode and hangs from top to bottom, can also laterally hang, according to the need of actual production and installation Change extension and pay mode, selectivity is more, easy to operate.

The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this Within the spirit and principle of utility model, any modification, equivalent substitution, improvement and etc. done should all be included in the utility model Within the scope of protection.
