Description
Technical field
The present invention relates to a kind of section bar link, in particular for the connection between the metal section of the framework of making furniture such as mirror holder, cupboard and desk and shelf, generally is the cross bar of framework of this series products and the connection between the montant.
Background technique
The section bar link of Xiao Shouing comprises lock housing, positioning block, first Returnning spring, lock shaft and screw rod in the market, be provided with in the lock housing from the open-ended lock shaft mounting hole of lock housing with from lock housing lateral opening positioning block mounting hole, lock shaft mounting hole and positioning block mounting hole intersect; Positioning block has the through hole that radially connects, and positioning block places the positioning block mounting hole, and the positioning block top has the screens boss, also offers the tapped hole that axially runs through the through through hole in screens projection top on the positioning block, and screw rod enters in the tapped hole; The front end of lock shaft has the fastener with institute's connection profile coupling, the bar portion side of lock shaft is provided with pit, have the inclined-plane that tilts from lock shaft rear end forward end in the pit, lock shaft mounting hole bottom is provided with first Returnning spring, insert in the lock shaft mounting hole rear end of lock shaft, and the through hole and first Returnning spring that pass positioning block offset, pit on the lock shaft is aimed at screw rod, through hole on this positioning block just only passes for lock shaft, and lock shaft passes that the screens boss of positioning block protrudes on the lock housing outer surface behind the through hole.But there are two defectives in this link, one, installation and removal on section bar are inconvenience extremely, and expend time in very much, main cause is because the lock shaft of this link can only just pass the positioning block through hole, at this moment positioning block has lock shaft to support, its screens boss is protruded on the lock housing outer surface, owing to there is this link of existence of screens boss can't directly insert in the cavity of section bar, and the screens boss is snapped in the positioning hole of section bar, often the screens boss is just blocked by the sidewall of section bar in the process of inserting, at this moment continue if desired to install just must screw out screw rod, lock shaft being extracted out just to make positioning block sink again, then existing link is inserted in the cavity of section bar, then the screens boss of positioning block is aimed at the positioning hole of section bar, could be inserted lock shaft thereafter screens boss come-up is snapped in the positioning hole of section bar, screw in screw rod at last, at this moment the installation process of whole link just finishes, and the process of dismounting link will experience so loaded down with trivial details process equally; Its two, this link is to the processing request height of part, the through hole of positioning block can not too greatly can not be too little, the screens boss of too big positioning block can't protrude the outer surface of lock housing, too little lock shaft can't pass at all.
Summary of the invention
Technical problem to be solved by this invention provides a kind of section bar link, this link need not the dismounting can be directly used in installations, the connection, operate very easy, and to manufacturing process require relatively low.
For this reason, section bar link provided by the invention comprises lock housing, positioning block, first Returnning spring, lock shaft and screw rod, be provided with in the lock housing from the open-ended lock shaft mounting hole of lock housing with from lock housing lateral opening positioning block mounting hole, lock shaft mounting hole and positioning block mounting hole intersect; Positioning block has the through hole that radially connects, and positioning block places the positioning block mounting hole, and the positioning block top has the screens boss, also offers the tapped hole that axially runs through the through through hole in screens projection top on the positioning block, and screw rod enters in the tapped hole; The front end of lock shaft has the fastener with institute's connection profile coupling, the bar portion side of lock shaft is provided with pit, have the inclined-plane that tilts from lock shaft rear end forward end in the pit, lock shaft mounting hole bottom is provided with first Returnning spring, insert in the lock shaft mounting hole rear end of lock shaft, and the through hole and first Returnning spring that pass positioning block offset, pit on the lock shaft is aimed at screw rod, the bottom of positioning block mounting hole is provided with block on the lock housing, is provided with second Returnning spring that two ends and positioning block bottom and block offset in the positioning block mounting hole; After lock shaft passes through hole, there is the activity space that moves up and down for positioning block between the bar portion of lock shaft and the inwall of through hole, the activity space of setting can make the screens boss on positioning block top protrude when positioning block is not subjected to external force on the positioning hole sidewall that the lock housing outside is clamped on the section bar of being installed, can make positioning block when the power that is subjected to lower compression, allow the screens boss in lock housing, bounce back, and break away from the positioning hole of the section bar of installing.
The bottom of the positioning block mounting hole of section bar link provided by the invention is provided with block, be provided with second Returnning spring between block and the positioning block, and the activity space that existence moves up and down for positioning block between the inwall of the bar portion of lock shaft and through hole, at this moment as long as push positioning block downwards, just can make it to sinking, and the screens projection on the positioning block just can not be stuck on the section bar sidewall when inserting the section bar cavity, as long as it is, simple to operation no matter be to install or remove all to press locating bump and again link is inserted or extracts out and can finish; In addition, because as long as through hole is made the diameter than the big H of lock shaft, and have second Returnning spring can remedy error on the size, so the existing link of the range of choice of the size of through-hole diameter goes out many, therefore relatively low to the technological requirement of processing when making greatly.
