Abstract

The utility model relates to a new movable bolt, which can solve the troubles that a plug post of an existing bolt can be hardly or not inserted into a socket hole, the plug post of an existing bolt needs to be disassembled, assembled and adjusted frequently because the wood window is deformed when the operating environment is changed. The new movable bolt is characterized in that the traditional form that the position of the existing socket hole is fixed is changed. The utility model makes use of the mechanical method to conveniently and quickly adjust the socket hole of the socket according to the deformation of the wood window to adapt to the deformation of the window. Thus, the plug pole can be guaranteed to be always inserted into the socket hole, and the bolt is in a usable state for a long time. The utility model is suitable for various environments and makes people's life more convenient.

Description

Movable bolt

With in the door and window, major part all adopts wooden structures in building construction.People usually need to fasten door and window with latch.And the latch form of extensively being used by people has at present had the history of decades, although the present latch that useful unlike material is made on the market and change the latch that appearance design is made, the citation form of these latches are still keeping the old form of original position, fixed socket hole.Because employed wooden the having nothing in common with each other of wooden door and window; and the environment of installing and using (containing temperature, humidity etc.) is also different; and same environment weather throughout the year is also inequality; the variation of these factors all can make wooden door and window generation distortion in various degree; so people usually can run into original mounted thumb-latch, the plug post is with regard to the misalignment socket aperture after after a while.Because after present latch installed, socket aperture can not at will be adjusted.In the time of can't using when plug post misalignment socket aperture occurring, the latch that a pair is very necessary can only become a secondary ornament, thereby loses its due effect.The people position that generally can readjust socket aperture adapts to plug post (or the position of adjusting the plug post adapts to socket aperture) in this case.But the distortion of door and window is that direction continuous and distortion sometimes is opposite, can occur the new socket aperture position of adjusting so not only but also to plug post just, people readjust the position of socket aperture again.So repeatedly adjust very trouble, and because repeatedly the distance of adjusting is little, the new screw hole of fixed socket and old screw hole are inevitable very approaching, screw will make the wooden structures of door and window be destroyed, and causes the fixing not firm phenomenon of latch to occur.Like this, this secondary latch also is unable to undergo impact more energetically, performs practically no function.

The purpose of this utility model be exactly for the socket aperture that overcomes old-fashioned latch because of fixed-site, make people produce the defective of inconvenience in use.Utilize mechanical means that socket is modified into the movable latch that the socket aperture potential energy freely moves up and down.Make plug post and socket aperture to not positive problem to solve because of wooden door and window is out of shape.

The socket aperture position can be regulated by easy on and off, can adopt multiple mechanical means to realize.But considering needs when using firmly, needs factors such as convenient, fast during adjusting, adopts structure as shown in the figure even more ideal.Below in conjunction with accompanying drawing the utility model is further described.

In the accompanying drawing: the 1-receptacle holders; 2-socket ear (hole); The 3-fixed head; The 4-spring;

The 5-place kick; The 6-screw; 7-plug frame; 8-plug post.

The utility model is made up of plug and socket two major parts as shown in the figure.

Plug is made of plug frame (7) and plug post (8).Its structure is the same with used plug substantially, just the plug post track with plug frame (7) improves certain distance, the braced structures that is about under the plug post is processed into convex, making latch install back plug post will be more greatly with comparing now to the distance of door and window, so that aim at the socket aperture of novel socket.

Fixing, movable two parts that socket is divided into again.Standing part is made up of receptacle holders (1).Standing part mainly plays the effect that socket is connected with the wooden door window frame, and no matter whether door and window is out of shape after installing, and all need not pull down later on and readjust.Movable part is to be assemblied by socket ear (2), fixed head (3), spring (4), place kick (5), screw (6).And the major part socket ear (2) of movable part and fixed head (3) are to be enclosed within on the receptacle holders (1), and socket ear (2) and fixed head (3) are coupled together with screw (6), make socket ear (2) and fixed head (3) to slide up and down, thereby make socket ear (2) just can adjust the position of socket aperture according to the distortion of wooden door and window according to receptacle holders (1).So just can solve door and window because of distortion, and plug post that produces and socket aperture position are to not positive problem.Often keep a relatively-stationary correct position for movable part is gone up in receptacle holders (1), be unlikely to always to drop on the bottom of receptacle holders (1) because of himself weight (when the plug post does not insert socket aperture).At the interior sidetracking of receptacle holders (1) the more shallow taper locating hole of a row, and be drilled with a hole in the inboard of the fixed head (3) of movable part, a spring (4) and a place kick (5) successively are housed in the hole.Make place kick (5) head on the inboard state of receptacle holders (1) like this, and can snap in the inboard some taper locating holes of receptacle holders (1), make movable part can not glide because of own wt because of being subjected to the elastic force effect of spring (4), being in all the time.

When needs are adjusted the socket aperture position, only need catch movable part firmly to push away (drawing) gently and move along required adjustment direction.At this moment, place kick (5) will be subjected to the pressure on the upper conical locating hole of receptacle holders (1) inclined-plane, and in the hole of the fixed head that spring (4) are housed (3), be retracted into, when moving to new taper locating hole, place kick (5) can be subjected to the elastic force effect of spring (4) again, again headed in the new taper locating hole, thereby finished the adjustment { there is row's taper locating hole the inboard of receptacle holders (1), and each pitch-row is a retaining } of a retaining.If wooden door and window distortion is bigger, can match up to socket aperture position and plug post position according to above-mentioned principle and several retainings of the many again accent of method.Whole adjustment process is less than finishing for two seconds.If having crossed a period of time door and window has distortion (or reversal deformation) again then can readjust the socket aperture position according to top described method and get final product.

Because the utility model is in the socket aperture adjustment process, do not destroy the wooden structures of door and window, thus can not occur because of repeatedly adjusting socket, and make jack system that unstable phenomenon is installed.Make users not only convenient but also relieved in use.
