Background technique
The principle of known at least this joint in the prior art.At this Georg Fischer type joint of quoting the central buffer mating system as example.
Particularly, be called as Georg Fischer connected member (GF connected member) and used with so that the mechanism that the mechanical connection between the joint of two joints breaks away from, this mechanism on 26S Proteasome Structure and Function similar in appearance to the said mechanism that constitutes by locking member, first actuation element, second actuation element and lever element.The particular type that depends on joint, separately both can be automatic program also can the time manual program.All joints of GF connected member all comprise locking member to prevent two involuntary disengagings of the mechanical connection between the joint that has engaged.Therefore, the mechanical connection between two joints in the GF connected member is fixed by two locking members.Therefore in order to make dockingundocking, two locking members all must be opened.
The mechanism that is used to two joints are broken away from is known in the prior art, and the operatively interactional common lever element of locking member of wherein general use and two joints will be so that they will break away from simultaneously by the actuating of lever element.Adopt the common lever element so that engage actuation element and reversal connection is closed the actuation element formation that can interact and is easy to realize and effectively be used to implement the solution of separation process.
But this mechanism has been shown only could not separated when the joint that has engaged bears tension loading smoothly.Particularly, under bigger tension loading situation, the locking member that existence keeps together these two joints that engaged can not be with the risk of cloth release.Its consequence is that locking member can not be broken away from prior to second locking member from power stream (force flow) and a locking member by band simultaneously, so tension force is applied to second locking member fully.In this case, usually no longer may or only may be difficultly that joint is more separated from each other.
As example, Fig. 1 illustrates Georg Fischer type joint 100 well known in the prior art, and it is in the state with identical contra adapter 100 ' engaged.Joint 100 has lever element 104 so that joint 100 and contra adapter 100 ' between mechanical connection break away from.Lever element 104 comprises first area 104a, and it is connected to the upper area of first actuation element 102 herein.In such cases, the tie point between the lever element 104 and first actuation element 102 is determined the vertical rotating shaft line, and lever element 104 can pivot around this axis.At its front area, lever element 104 is in abutting connection with the upper area of second actuation element 103.Two actuation elements 102,103 are respectively by locking member 106,106 ' be connected.Locking member 106,106 ' be used for together with joint 100,100 ' pressure assembling (force-fit).
For two joints 100,100 separately ', actuation lever 104 is along direction of arrow deflection, the result vertically is pulled away from joint 100 by first actuation element 102 that lever element 104 is connected to first area 104a.Because first actuation element 102 is connected directly to locking member 101, the power transmission of generation is sent to second open position with locking member 101 from first closed position.
Simultaneously, when lever element 104 deflections, contra adapter 100 ' second actuation element 103 ' by the reaction force on the second area 104b of lever element 104 be pressed into contra adapter 100 '.Second actuation element 103 ' also be connected to lever element 101 ', and be used for equally locking member 101 ' be sent to second open position from first closed position.
Second actuation element of describing among Fig. 1 103 ' therefore be connected to contra adapter 100 ' locking member 101 '.
In ideal conditions, after lever element 104 deflection, joint 100 and contra adapter 100 ' its open position of locking member 101,101 ' will be in and two joints 100,100 ' can be separated from each other.
But often can not be prevented from separation process middle joint 100,100 ' may be in the fact under the tension loading.Therefore there is actuation element 102,103 ' will block and do not allow the risk of relevant locking member 101,101 ' open.But in the solution known in the prior art, another actuation element that does not block 102,103 ' might be still can activity and the corresponding locking member 101,101 of release '.Whole then tension loading be passed to another joint 100,100 ' locking member 101,101 '.Joint 100,100 ' can not easily separate consequently.
Summary of the invention
On the basis of problem set forth above, the objective of the invention is further to improve the joint of the described type of beginning, even so that be under the bigger tension force, engage and also can break away from smoothly.
This purpose is that the theme by independent claims 1 solves.Favourable improvement of the present invention is illustrated in the dependent claims.
Solution of the present invention is characterised in that in the joint of described type when bearing additionally is arranged on beginning, in order to the lever element between supporting first area and the second area, so that lever element can pivot around the vertical axis that can limit in advance.
In order to realize this purpose, for the first area of lever element and the lever element between the second area are determined horizontal axis of rotation, wherein determined or can limit two translation freedoms in advance at least, so that lever element only can pivot around spin axis for lever element.The pivot movement of determining lever element can prevent effectively that another locking member is opened when the locking member of a joint blocks.For this effect, spin axis is assigned to lever element, and its assurance is connected to the even distribution of the power on two actuation elements of locking member.Therefore this guarantees the synchronous actuating of actuation element, and guarantees that locking member will be opened always simultaneously.Therefore, joint is broken away from.Disengaging prevents that further they are damaged in the time of locking member, because element can not bear tension force separately.
A preferred implementation bearing of creative solution is set to have the vertical shaft of the vertical pivot axis line that limits lever element.Can expect that thus this axle removably is attached to joint.Do for example allowing easily to renovate traditional jointing like this, traditional jointing does not guarantee the simultaneously operating of locking member under the state that it is in contra adapter engages.
For example can expect that axle removably is attached to the casing frame on the joint, wherein casing frame has the space, and lever element is parallel to composition plane and is pivoted in the space around axle.Thereby this variant allows to select the scope that rotatablely moves of geometrical shape restriction lever element of casing frame to engaging and separating required angular range in especially favourable mode.
Certainly, also can expect being suitable for determining other solution of the range of pivot of lever element, for example preferably removably be connected to the stop element of joint.
In the advantageous embodiment of creative solution, the bearing that is set up in order to the supporting lever element has axle, this is accommodated in along in the groove of direction of engagement extension, so that axle is directed along direction of engagement by the pivot of lever element, thereby compensating shaft and lever element are hinged with the variation of lever arm on length between the first area of end regions of first actuation element.When lever element deflection, power is passed to locking member via first actuation element.Since first actuation element can be preferably with respect to joint only perpendicular to the direction of engagement motion, so decision design is connected to the lever element of actuation element, so that the circular movement of described lever element can be converted into vertical motion.This can realize in simple and economic mode by axle is directed in the groove that extends along direction of engagement.
Further advantageously, provide the lever element with elongated hole, first actuation element is removably attached in this elongated hole.Elongated hole allows first actuation element to fix and be mounted to pivotly lever element.Therefore the first actuation element preferred bolt is connected to lever element.This makes these two elements firmly connect, and repairs if desired, and one of them can easily break away from.
At last, the favourable implementation of joint provides guide on the end regions of second actuation element, thereby by the second area of the lever element relevant with contra adapter with respect to pivot guiding relevant lever element with contra adapter of the end regions of second actuation element.For example can expect that guide comprises the guide groove that extends along direction of engagement.
