Abstract
The utility model relates to a locking plug pin structure, which overcomes the defect that a locking plug pin with an inclined plane is difficult to plug and pull and the tightness degree of plugging and pulling is not easy to control in the prior art. The adopted technical proposal is that the locking plug pin comprises a locking bolt, a connecting rod, a spacer bush, a connecting pin and a locking block with a locking inclined plane; the connecting rod is sleeved in a central hole of the locking bolt to form the movable connection of relative rotation between the connecting rod and the locking bolt, the other end of the connecting rod is connected with the locking block, the connecting pin is arranged on the locking block through the connecting rod to form a fixed connection structure of the connecting rod and the locking block, the spacer bush is sleeved on the connecting rod between the locking bolt and the locking block to form a connection structure of the connecting rod and the locking bolt which can relatively rotate and have fixed axial positions. The utility model has the advantages that: the structure is simple, quick locking or loosening of the locking plug pin can be achieved, and simultaneously the connection is firm and the positioning is accurate, so the utility model is particularly suitable for positioning and connecting of components requiring quick, convenient and accurate installation.
Description
Affiliated technical field
The utility model relates to a kind of locking link, particularly a kind of latch structure that is used to lock connection usefulness.
Background technique
Using latch that product component is connected and locking is the design proposal of often using in the Machine Design, adopt in the locking latch prior art of being with the inclined-plane use is also arranged, but the locking latch plug prior art on band inclined-plane is to make the insertion of locking latch lock or withdraw from and unclamp by external force is mandatory, make troubles to use, as forming large LED display screen on the square by a plurality of LED displays, when use the public arena, all be to adopt the locking latch that the housing of a plurality of LED displays is linked into an integrated entity between a plurality of LED display housings, also do not have desirable locking latch structure to be used for using on this product in the prior art.
Summary of the invention
For overcoming the locking latch plug difficulty on band inclined-plane in the prior art, the uppity shortcoming of plug tightness, the utility model designs a kind of locking latch structure, and this locking latch drives tight inclined-plane with lock by the lock bolt and the relative rotation of set screw nut locking block is realized the locked of check lock lever with cooperating of the check lock lever of tieholen with lock or unclamped.
The utility model realizes that the technological scheme that goal of the invention adopts is, a kind of locking latch structure, this locking latch comprises: lock bolt, connecting rod, spacer, the locking block on connecting pin and tight inclined-plane with lock, described connecting rod is sleeved in the interior center hole of lock bolt, constitute connecting rod and the relatively turnable flexible connection of lock bolt, the other end of connecting rod is connected with locking block, connecting pin is arranged on the locking block by connecting rod, constitute the fixed connection structure of connecting rod and locking block, spacer is sleeved on the connecting rod between lock bolt and the locking block, constitutes that connecting rod and lock bolt can relatively rotate and axial position is fixedly coupled structure.
The beneficial effects of the utility model are, and are simple in structure, can realize locking latch and lock fast or unclamp, and connect firm, accurate positioning simultaneously, need to be specially adapted to fast, convenient, the accurately mounted component use that is located by connecting.
Below in conjunction with accompanying drawing the utility model is elaborated.
Accompanying drawing 1 is the utility model generalized section.
Accompanying drawing 2 is an accompanying drawing 1A-A generalized section.
Accompanying drawing 3 is an accompanying drawing 1B-B generalized section.
Accompanying drawing 4 is that accompanying drawing 1C is to schematic representation.
Accompanying drawing 5 is that accompanying drawing 1D is to schematic representation.
Accompanying drawing 6 is the utility model user mode schematic representation.
In the accompanying drawing, 1 lock bolt, 2 connecting rods, 3 spacers, 4 connecting pins, 5 locking blocks, 6 locking inclined-planes, 7 check lock levers, 8 set screw nuts.
Embodiment
Referring to accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, accompanying drawing 4 and accompanying drawing 5, a kind of locking latch structure, this locking latch comprises: lock bolt 1, connecting rod 2, spacer 3, the locking block 5 on connecting pin 4 and tight inclined-plane 6 with lock, described connecting rod 2 is sleeved in the lock bolt 1 interior center hole, constitute connecting rod 2 and lock bolt 1 relatively turnable flexible connection, the other end of connecting rod 2 is connected with locking block 5, connecting pin 4 is arranged on the locking block 5 by connecting rod 2, constitute the fixed connection structure of connecting rod 2 and locking block 5, spacer 3 is sleeved on the connecting rod 2 between lock bolt 1 and the locking block 5, constitutes that connecting rod 2 can relatively rotate with lock bolt 1 and axial position is fixedly coupled structure.
During use, referring to accompanying drawing 6, select the tight bolt 1 of twist lock, lock bolt 1 is under the effect of set screw nut 8, carry out moving along axis, connecting rod 2 pulling locking blocks 5 move along axis with lock bolt 1, and axial position is fixed because connecting rod 2 can relatively rotate with lock bolt 1, so connecting rod 2 drives 5 of locking blocks and moves along axis with lock bolt 1, tighten inclined-plane 6 and realize the locking of check lock lever 7 by the tieholen with lock on the check lock lever 7 or unclamp.
The utility model embodiment is for making lock bolt 1 easy to use, and lock bolt 1 one ends are the screw rod of screw thread, and the other end is a hexagon nut.The convenient conventional tool that uses of hexagon nut is implemented the control rotation to lock bolt 1.
The utility model embodiment is applicable to different use needs, and the transverse section of described locking block 5 can be designed to rectangle, circle and other shape.
The utility model embodiment is the surface friction drag and the processing of being convenient to locking block 5 of minimizing locking inclined-plane 6 with the locking hole that cooperates, described locking inclined-plane 6 be arranged on separately locking block 5 above, the horizontal width on locking inclined-plane 6 is less than the horizontal width above the locking block 5 or the diameter of locking block 5.
