Abstract
A back springing type spring latch firmware, includes a cap sleeve, is sheathed on a liner sleeve in cap sleeve, through liner sleeve and be linked to a locking bar and the elastic element in cap sleeve; Wherein, be formed with a blocked part and extend the locking part outside cap sleeve on locking bar, elastic element is arranged at formed holding space between the top cover portion of liner sleeve and blocked part; Form whereby, when elastic element is extended configuration, via elastic element ejection, normality remains on locking part and stretches out the locked position of coupler outside liner sleeve locking bar; When pulling open in the opposite direction with respect to liner sleeve via cap sleeve and making elastic element be compressive state, locking bar meeting synchronizing moving is to being reduced to a lockset position of coupler of neck bush cylinder in locking part.
Description
Technical field
The utility model relates to a kind of locking bar under normal conditions and remains on locked position of coupler, and can locking bar conversion be moved to via operation to the back springing type spring latch firmware of lockset position of coupler.
Background technique
Based on comparatively trouble and the inconvenience in the use of general screw, just developed afterwards and there is against shock and come off, can also avoid using the floating spring screw of screwdriver simultaneously.
M457090 as novel in TaiWan, China has disclosed a kind of positioning device, and the structure of taking off is the floating spring screw of general common name; This positioning device mainly includes the members such as cap sleeve, locating piece, the body of rod, gland, extending sleeve, fixed base and elastic element; Form by this kind ofly under elastic element keeps extended configuration, elastic element ejects fixed base downwards and makes gland to remain on the floating spring screw in fixed base.
This floating spring screw can utilize fixed base root edge to be fixed in advance in the open-work of a plate to be forced into the modes such as build-in or solid welding; After pressing cap sleeve downwards, can allow extend and be placed on the fixed base outside mobile elastic element generation resiliently deformable that forces down, and the gland that makes locating piece below passes fixed base to lower outer, through the open-work of plate, be locked in through hole corresponding to another object.
Yet after using floating spring screw to lock, inner elastic element will remain under hard pressed state always, when maintaining for a long time under this state, may there is elastic fatique phenomenon in elastic element, reduces floating spring screw durability.
In addition, at floating spring screw, be fixed in the installation process of open-work of a plate, the effect that is subject to elastic element due to floating spring screw presents quick condition, makes often to occur installing on installation exercise be difficult for or puzzlement not in place is installed.
Model utility content
In view of this, main purpose of the present utility model is to propose a kind of elastic element of can avoiding and occurs elastic fatique, and in installation process, can avoid producing and float, and after installation, can locate and remain at lockset position of coupler, allow the installation exercise that continues can be more fast and convenient and the road of the solution of location is positively installed; Base this, the utility model proposes a kind ofly after locking, elastic element can not continue to maintain under hard pressed state, avoids elastic element to produce elastic fatique, and can effectively improve durability and be easy to the technological scheme of installing and using.
For reaching above-mentioned purpose, the utility model proposes a kind of back springing type spring latch firmware, include:
One cap sleeve, is formed with a containing space;
