The utility model designs a kind of self-locking device pull piece, it is characterized in that, comprising:
Pull piece, comprises manual manipulation part and sub-frame machine dish coupling part, and be provided with shaft hole on the plate being positioned at manual manipulation part;
Buckle, is sheathed in the described manual manipulation part of described plate;
Pin, is threaded onto described shaft hole, to be fixed on mobilizable for described buckle on described pull piece.
Above-mentioned self-locking device pull piece, is characterized in that, the described manual manipulation part of described pull piece is also provided with groove, and is also connected with spring leaf on the inwall of this groove, so that described buckle is realized resilience and fastening by described spring leaf.
Above-mentioned self-locking device pull piece, is characterized in that, described buckle and described manual manipulation portion connection are provided with the second shaft hole.
Above-mentioned self-locking device pull piece, is characterized in that, described buckle is arranged the hook of fixation together.
Above-mentioned self-locking device pull piece, is characterized in that, described sub-frame machine dish coupling part comprises rotating hole and plug.
Above-mentioned self-locking device pull piece, is characterized in that, the material of described self-locking device pull piece is aluminium alloy.
Above-mentioned self-locking device pull piece, is characterized in that, described pull piece is Hippocampal shape.
The utility model has following advantage and good effect:
1, the self-locking of pull piece is achieved in the elasticity of very little space utilization spring leaf and buckle;
2, the head of pull piece meets human engineering aesthetics, handled easily, good looking appearance;
3, make simply, with low cost, be applicable to helping of machine dish in all communication equipments and pull out self-locking mechanism.
Accompanying drawing explanation
With reference to appended accompanying drawing, to describe embodiment of the present utility model more fully.But, appended accompanying drawing only for illustration of and elaboration, do not form the restriction to the utility model scope.
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structural representation.
Embodiment
In order to make the technical solution of the utility model and advantage easy to understand more, be described in further detail below in conjunction with accompanying drawing.Should illustrate, specific embodiment described herein only in order to explain the utility model, and is not used in restriction the utility model.
A kind of self-locking device pull piece, the aluminum alloy die casting of two main bodys is combined by spring leaf and rotating shaft, be installed on single board and just can realize its plug and fixed function in the rear guide rail inserting complete machine, greatly reduce because of cause without this structure overexert time the damage that causes, the problems such as distortion.
As depicted in figs. 1 and 2, the utility model relates to key components and parts in optical transport and the sub-frame of PON communication apparatus, be a kind of plug for single functional disc and pull out and locking device with helping of auto-lock function, comprising the pull piece 1 in Hippocampal shape, pull piece 1 comprises manual manipulation part 22 and sub-frame machine dish coupling part 21, manual manipulation part 22 is thinner than sub-frame machine dish coupling part 21, is provided with rotating hole 15 and plug 16 in sub-frame machine dish coupling part 21; The manual manipulation part 22 of pull piece 1 is provided with a groove 11, and on the inwall of groove 11, coupling is connected with spring leaf 3, and this spring leaf 3 is the spring leaf that a kind of thin steel spring plate curves, and has both taken up room little, effectively can play again the effect of reset.
The groove 12 of buckle 4 is sheathed on the manual manipulation part 22 of pull piece 1, buckle and pull piece 1 manual manipulation part 22 junction are provided with the second shaft hole 13, the first shaft hole 14 on pull piece 1 and the second shaft hole 13 on buckle are alignd, afterwards rotating shaft pin 2 is inserted the first shaft hole 14 and the second shaft hole 13 is installed fixing, the entirety realizing whole mechanism is complete, buckle 4 is arranged the hook 17 of fixation together, buckle 4 can have the deflection of certain angle around pin 2, thus make buckle 4 realize resilience and fastening by the elastic force of spring leaf 3, the object convenient with the installation of closing is convenient to out to reach.
The manual manipulation part 22 of pull piece 1 is done thin by the utility model as far as possible, buckle 4 thickens under the condition of license, the buckle 4 thickened is offered a groove 12, when extruding buckle 4, around pin 2, buckle 4 can have the deflection of certain angle, realizes the resilience of buckle 4 after fastening under the effect of spring leaf, has enough spaces to put manual manipulation part 22 in groove 12.Total seems compact, not only strengthen the structural strength of pull piece to reach but also make the comfortable feel that operates, outward appearance seems round and smooth attractive in appearance, pull piece main body and buckle are all made die casting by the utility model, coarse process on buckle, to increase frictional force when gripping, surface applies landscaping treatment again.
Mechanism structure is simple, and volume is little and cheap, effectively can realize each functional cards plug object freely, solve simultaneously high density communication apparatus handset frame do not have suitable pull piece can contradiction.
By illustrating and accompanying drawing, giving the exemplary embodiments of the ad hoc structure of embodiment, based on the utility model spirit, also can do other conversion.Although above-mentioned utility model proposes existing preferred embodiment, but these contents are not as limitation.
For a person skilled in the art, after reading above-mentioned explanation, various changes and modifications undoubtedly will be apparent.Therefore, appending claims should regard the whole change and correction of containing true intention of the present utility model and scope as.In Claims scope, the scope of any and all equivalences and content, all should think and still belong in intention of the present utility model and scope.
