Description
Technical field
The utility model relates to a kind of snap close piece, a kind of novel rotating latch of specific design.
Background technology
Snap close piece on the market is mostly divided into two large classes: a class is the magnetic-type snap close utilizing magnet, and another kind of is the mechanical type snap close utilizing latch or hook, however this two classes snap close in actual use often denounce by user.First be magnetic-type snap close, be utilize magnetic box with holes and the irony pin thread with the projection corresponding with box hole, in use procedure, make because box is magnetic material, other ironwork to be adsorbed except pin thread, affects it and normally use; In addition, because the service life of magnetic material limit, this type of magnetic-type snap close, often ineffective because the magnetic of box weakens.The second mechanical type snap close, what it utilized is after pin thread and box cooperatively interact, then installs latch additional or hook-shaped structure ensures that it is sealed, but due to latch and hook structure fragile and easily lose, bring many inconvenience to user.
Also have a kind of rotating latch at present, it utilizes tapered end to rotate, and controls the sealed of pin thread and box and opens, such as: when tapered end is horizontal level, because tapered end length is shorter than the length in box hole, so snap close is in open mode; When tapered end is vertical position, because tapered end length is longer than the width in box hole, so snap close is in locked state.But in actual use, due to the effect of external force, snap close may shake or slightly shake, tapered end is easy to be offset by vertical position, causes snap close oneself and opens.
Utility model content
For solving the problem of above-mentioned prior art, the utility model provides a kind of novel rotating latch, and concrete technical scheme is as follows:
A kind of novel rotating latch, comprise box fixed head, box, pin thread fixed head, pin thread and tapered end, described box fixed head is " returning " shape structure, described fixed head central authorities offer square hole, two minor face centre positions of this fixed head offer through hole, and the side of this fixed head is through anti-skidding process; Described box structure is corresponding with box fixed head, and offer square hole in the middle of this box, the limit of this square hole is shaped to " mouth " shape lug to side, the outside of described lug two minor face forms screw thread trepanning; Described pin thread fixed head is rectangle platy structure, and fixing hole offered by described pin thread fixed head; Described pin thread is " convex " shape cavity structure, the upper end of described pin thread offers lock cylinder aperture, described through hole aperture offers " ten " shape groove, tapered end trepanning is formed below this through hole, described through hole both sides form locating dowel downwards, and below " convex " shape cavity of described pin thread, the position corresponding with locating dowel is provided with rectangular card contact pin; Described tapered end is rectangular structure, and the bottom center of this tapered end forms lock, forms " ten " shape protruding bottom described tapered end along the position that locating dowel circumference is corresponding with " ten " shape groove.
Further, described lock through the tapered end trepanning below pin thread, and has elastomeric spring at it.
Further, the length of described lock is greater than the length of tapered end trepanning.
Further, the anti-skidding process of described box fixed head 1 is shaping tread plate thereon in the present embodiment, also can install slipmat additional thereon.
Further, the fixed connection method that described lock and tapered end sleeve, locating dowel and clamping sheet adopt is all adopted to roll by column cap to be out of shape at hole extenal fixation.
Further, the fixing hole number on described pin thread fixed head is at least two.
The beneficial effects of the utility model are:
A kind of novel rotating latch that the utility model provides, the projection of pin thread is corresponding with the square hole of box, then utilizes the rotation of the tapered end be fixed on pin thread to control the sealed of this snap close and to open.Owing to pin thread offering " ten " shape groove, below tapered end, there is projection corresponding with it, due to the effect of elastomeric spring below lock, tapered end is stablized at sealed or open mode upper/lower positions, slippage can not occur, Stability Analysis of Structures, long service life.The utility model is simple due to its structure, is not limited to case and bag, packing box snap close, and can also use in fields such as hardware machinery, dress and personal adornment, footwear decorations, range of application is very wide.

Detailed description of the invention
Now by reference to the accompanying drawings the utility model is further illustrated:
A kind of novel rotating latch as Figure 1-10 shows, comprise box fixed head 1, box 2, pin thread fixed head 3, pin thread 4 and tapered end 5, described box fixed head 1 is " returning " shape structure, described fixed head 1 central authorities offer square hole, two minor face centre positions of this fixed head 1 offer through hole 11, and the side of this fixed head 1 is through anti-skidding process; Described box 2 structure is corresponding with box fixed head 1, and offer square hole in the middle of this box 2, the limit of this square hole is shaped to " mouth " shape lug 22 to side, the outside of described lug 22 liang of minor faces forms screw thread trepanning 21; Described pin thread fixed head 3 is rectangle platy structure, and fixing hole 31 offered by described pin thread fixed head; Described pin thread 4 is " convex " shape cavity structure, the upper end of described pin thread 4 offers lock cylinder aperture 41, described through hole 41 aperture offers " ten " shape groove 42, tapered end trepanning 45 is formed below this through hole 41, described through hole 41 both sides form locating dowel 44 downwards, and below " convex " shape cavity of described pin thread 4, the position corresponding with locating dowel 44 is provided with rectangular card contact pin 43; Described tapered end 5 is rectangular structure, and the bottom center of this tapered end 5 forms lock 51, forms " ten " shape projection 52 bottom described tapered end 5 along the position that lock 51 circumference is corresponding with " ten " shape groove 42.
Described lock 51 through the tapered end trepanning 45 below pin thread, and has elastomeric spring at it.
The length of described lock 51 is greater than the length of tapered end trepanning 45.
The anti-skidding process of described box fixed head 1 is shaping tread plate 12 thereon in the present embodiment, also can install slipmat additional thereon.
The fixed connection method that described lock 51 adopts with clamping sheet 43 with tapered end sleeve 45, locating dowel 44 is all adopted to roll by column cap to be out of shape at hole extenal fixation.
