Description
Technical field
The utility model relates to the fixing securing means that a kind of industry or civilian installation use, relate generally to be used on indoor, outdoor fixing and movement equipment can safety protection, again dismountable connection facility.
Background technique
Clamping bolt nut used at present, all adopts exposed direct dismountable structure outside.Both unsightly and very low to the safe precaution ability of its equipment.In order to prevent being disassembled, occurred some technological schemes in the prior art, but its structure is more complicated, and application area is not too extensive.Our patent (patent No. ZL201320827992.6) is non-removable full securing means, and this is the half of the design's core technology series.Complete second half the design of application series on this basis, namely dismountable safety protection connects facility, completes the design of this core technology of application complete series product.
Summary of the invention
The purpose of this utility model is that a kind of dismountable safety protection of invention connects facility, to the in addition expansion functionally of current non-removable securing means.
The purpose of this utility model is achieved through the following technical solutions:
A kind of dismountable safety protection connects facility, forms primarily of protecting cover, anti-guard housing and back-up ring; Protecting cover diameter of bore and anti-guard housing outer diameter are Spielpassung; The inwall of protecting cover is provided with protecting cover annular groove, and the outer surface of the anti-guard housing of position is provided with anti-guard housing annular groove corresponding thereto; Described back-up ring is circular, is placed between protecting cover annular groove and anti-guard housing annular groove; The internal diameter of back-up ring is less than the groover rot diameter of anti-guard housing annular groove; On protecting cover, be positioned at the position of protecting cover diameter of bore and anti-guard housing outer diameter, be provided with one from top to bottom with the pilot hole of parallel to an axis; At the outer surface of anti-guard housing, be positioned at the position of protecting cover diameter of bore and anti-guard housing outer diameter, be provided with the axis hole that a circle is relative in the axial direction with pilot hole.
The top endoporus of protecting cover is up-small and down-big conical surface,
Protecting cover annular groove contains back-up ring completely in wherein, and anti-guard housing annular groove radial direction holds 1/2 of back-up ring.
Straight pin is plugged with in the axis hole of the outer surface of anti-guard housing.
The holding space laying bolt, nut, axle or pin is defined between protecting cover 1 and anti-guard housing.
The design's structure is simple, and anti-guard housing can be made into the practical part of multiple mechanical function, extends the direct protective range of lockset, and size can be done very little, and existing minimum protecting cover diameter is only 9.5mm at present, height 5.7mm.After the assembling of this facility, back-up ring is positioned in the middle of D/d fitting surface, limits protecting cover and the movement to axial of anti-guard housing, therefore anti-guard housing is wherein played to the safeguard function preventing from axially opening; Protecting cover is relative with anti-guard housing simultaneously can turn round, and has again the safeguard function preventing from twisting off destructive dismounting by force.Therefore this facility has possessed the function of lockset because opening.Opener, opening ways are different from current all locksets, are therefore new varieties of mechanical lock development.And anti-guard housing can be made into the practical part that maybe can hold multiple mechanical function, extends direct protective range.
Accompanying drawing explanation
Fig. 1 is the structural representation of this connection facility,
Fig. 2 is the A-A sectional view in Fig. 1.
In figure: 1. protecting cover, 2. anti-guard housing, 3. back-up ring, 4. pilot hole, 5. straight pin, 6. holding space, 7. protecting cover annular groove, 8. anti-guard housing annular groove, D. protecting cover diameter of bore, the anti-guard housing outer diameter of d..
Embodiment
See Fig. 1 and Fig. 2, the utility model is that a kind of dismountable safety protection connects facility, forms primarily of protecting cover 1, anti-guard housing 2 and back-up ring 3.The top endoporus of protecting cover 1 is up-small and down-big conical surface, and protecting cover diameter of bore D and anti-guard housing outer diameter d is Spielpassung, has two degrees of freedom, can relatively rotate and move axially during cooperation.The inwall of protecting cover 1 is provided with protecting cover annular groove 7, and the outer surface of the anti-guard housing 2 of position is provided with anti-guard housing annular groove 8 corresponding thereto.Described back-up ring 3 is circular, is placed between protecting cover annular groove 7 and anti-guard housing annular groove 8.Protecting cover annular groove 7 can contain back-up ring 3 completely in wherein, and anti-guard housing annular groove 8 radial direction can hold 1/2 of back-up ring; Internal diameter before back-up ring 3 assembles is less than the groover rot diameter of anti-guard housing annular groove 8.On protecting cover 1, be positioned at the position of protecting cover diameter of bore D and anti-guard housing outer diameter d, be provided with one from top to bottom with the pilot hole 4 of parallel to an axis.At the outer surface of anti-guard housing 2, be positioned at the position of protecting cover diameter of bore D and anti-guard housing outer diameter d, be provided with the axis hole that a circle is relative in the axial direction with pilot hole 4, when disassembled, in axis hole, be plugged with straight pin 5.In order to lay the function parts such as protected bolt, nut, axle, pin between protecting cover 1 and anti-guard housing 2, between protecting cover 1 and anti-guard housing 2, define the holding space 6 laying described bolt, nut, axle or pin.
In Fig. 1 and Fig. 2, what the left side of two figure represented is when straight pin 5 is inserted in the situation between protecting cover 1 and anti-guard housing 2 by pilot hole 4, and what the left side of two figure represented is the situation that straight pin 5 does not insert.Can see from figure, in right-hand part figure, back-up ring 3 keeps off between protecting cover annular groove 7 and anti-guard housing annular groove 8, plays the effect of Anti-dismantling; In the figure of left side, because straight pin 5 is inserted in the anti-guard housing annular groove 8 of anti-guard housing 2 successively, be pushed into by back-up ring 3 in protecting cover annular groove 7, anti-guard housing 2 can be extracted downwards in protecting cover 1.
The installation process that safety protection connects facility is: be first loaded in protecting cover annular groove 7 by back-up ring 3; Again protecting cover 1 is pressed into anti-guard housing 2.In process of press in, back-up ring 3 is progressively expanded by the conical surface on anti-guard housing 2 top, until be pressed completely into after in protecting cover annular groove 7, the cylndrical surface of continuing along anti-guard housing 2 axle is moved, until enter in anti-guard housing annular groove 8, and hold tightly under the effect of back-up ring 3 tension force in anti-guard housing annular groove 8.
The opening process that safety protection connects facility is: aligned with anti-guard housing annular groove 8 successively by the pilot hole 4 on protecting cover 1 with special tool (correcting pin); And the straight pin 5 of dismounting is filled in the anti-guard housing annular groove 8 of people 5 successively, straight pin 5 is pressed onto the end; After straight pin 5 is all installed, back-up ring 3 is easily inserted into the expanded the annular groove having departed from anti-guard housing annular groove 8, enters in the protecting cover annular groove 7 of protecting cover 1, and now protecting cover 2 does not have the obstruction of back-up ring 3 to move axially unlatching.
