The purpose of this utility model be between ball head connecting rod and hold-down head, form one have the location, reset, the spring pad of damping, shock-absorbing effect, when some deviations being arranged with convenient bulb center and glass center of gravity, under the effect that does not have external force, hold-down head and the glass of being fixed thereof can be in desirable initial position automatically, and reach when the glass angle is changed when external force, it has the resetting of spring-like, damping, shock-absorbing effect.

For achieving the above object, the utility model adopts following technical scheme: a kind of universal overlapping joint improves structure, comprise refuting and connect pawl and overlapping joint two parts, overlapping joint is made up of ball head connecting rod, hold-down head, lining, locating ring, retaining ring, locking nut etc., and the tail end of the ball head connecting rod of overlapping joint will be refuted by locking nut and be connect pawl and overlapping joint fuses; Hold-down head and locating ring be opposed to be connected and to have an interior sphere curved surface that the bulb part with ball head connecting rod is complementary fully, and bulb is positioned among the sphere curved surface of described hold-down head and locating ring composition; The bulb top of ball head connecting rod and hold-down head internal cavities respectively have a platform, and the outside of locating ring is toroidal, and in packing hold-down head into from the rear portion; It is characterized in that: it offers a circular hole at the bulb terrace part of the ball head connecting rod of original overlapping joint, wherein add a rubber tip, the ball head connecting rod that has rubber tip is locked between hold-down head and the locating ring, and rubber tip contacts with the hold-down head inner platform.

The utility model compared with prior art owing to used valve rubber, reduces the susceptibility of bulb center, and mechanism element requirement on machining accuracy and install and adjust difficulty and decrease provides cost savings.

Description of drawings of the present utility model is as follows:

Fig. 1 is a countersunk head structural representation of the present utility model;

Fig. 2 is a plush copper structural representation of the present utility model;

Fig. 3 is an extrusion pressing type structural representation of the present utility model.

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

As depicted in figs. 1 and 2, universal overlapping joint of the present utility model improves structure, comprise refuting and connect pawl and overlapping joint two parts, overlapping joint is made up of ball head connecting rod 3, hold-down head 2, lining 1, locating ring 4, retaining ring 6,

locking nut

7,9 etc., and the tail end of the ball head connecting rod 3 of overlapping joint will be refuted by locking

nut

7 and 9 and be connect pawl and overlapping joint fuses; Hold-down head 2 and locating ring 4 be opposed to be connected and to have an interior sphere curved surface that the bulb part with ball head connecting rod 3 is complementary fully, and bulb is positioned among the sphere curved surface that described hold-down head 2 and locating ring 4 form; The bulb top of ball head connecting rod 3 and hold-down head 2 internal cavities respectively have a platform, and the outside of locating ring 4 is toroidal, and in packing hold-down head 2 into from the rear portion; It is characterized in that: it offers a circular hole at the bulb terrace part of the ball head connecting rod 3 of original overlapping joint, wherein add a rubber tip 10, the ball head connecting rod 3 that has rubber tip 10 is locked between hold-down head 2 and the locating ring 4, and rubber tip 10 contacts with hold-down head 2 inner platforms.

Owing to increased rubber tip, it is an elastic body with certain rigidity that hold-down head 2 and ball head connecting rod 3 are linked to be, as there is not an effect of certain external force, hold-down head 2 and the glass of being fixed thereof can be in desirable initial position automatically, even bulb center and glass center of gravity also are like this when some gaps are arranged, the installation adjustment of glass becomes easier, and reaches when the glass angle is changed when external force, and rubber tip has the resetting of spring-like, damping, shock-absorbing effect.

This overlapping joint that can change angle as required arbitrarily is that the universal overlapping joint in the universal overlap-connected components improves structure, and it is to separate a circular hole in the platform part of the ball head connecting rod 3 of original overlapping joint, installs a rubber tip 10 additional.Have 3 compacted 2 of the ball head connecting rods and locating ring 4 latched positions of rubber tip 10, rubber tip 10 contacts with hold-down head 2 inner platforms with certain pressure.

Improve in the structure at universal overlapping joint, on the one hand, the glass of hold-down head 2 and clamping thereof still can be realized the angular displacement of any direction around the bulb of ball head connecting rod 3, when adjusting to satisfy to the requirement of angle; On the other hand, because this thick valve rubber of rubber tip has been arranged, as do not have certain external force effect, compacted 2 glass of being fixed is in desirable initial position automatically, even bulb center and glass center of gravity also are like this when some gaps are arranged; And when external force reaches the angular deflection that can make glass produce any direction, the capital produces to the slippage tendency of hold-down head 2 inner surfaces and the compressive strain on the respective direction valve rubber, because locating ring 4 has applied certain pretightning force to rubber tip when locking ball head connecting rod 3, make the platform in it and the hold-down head 2 and the periphery of bulb circular hole produce big friction, during glass deflection, must overcome friction and elastic deformation resistance, whole process is in deflection external force and above two equilibrium of forces states constantly, it is a controlled flexible progressive formation, it is very steady all the time to move, there is not the sudden change of power and speed, shock and vibration have been avoided, for operating period very long curtain wall construction and brittle glass material, this point is very important.And when the external force that makes the glass deflection angle reduced or disappears, the angle of glass deflection can automatically restore to smaller angle or original state, and promptly this structure has location and the reset capability to initial position; See that further when the glass deflection angle was big more, deformation drag also increased thereupon, and its deflection speed is slowed down thereupon, in its maximum deflection position---during final position, speed levels off to zero, has promptly avoided the rigid shock of structure.Therefore rubber is paid somebody's debt and expected repayment later the effect of playing damping, shock-proof spring.

In sum, this structure makes the change of glass angle become a controlled flexible progressive formation, both had stationkeeping ability to initial position, also has the reset capability after the varied angle, under the effect of rubber elasticity pad, avoided the generation of rigid shock, the whole baffle wall structure is played damping, shock-absorbing effect, is the important improvement of overlapping joint structure.

Except valve rubber, universal overlapping joint improves the basic structure that structure still keeps former overlapping joint, as sphere curved surface, and platform structure and horn mouth etc., it is with to refute the connected mode that connects pawl also constant.

As Fig. 3, this universal overlapping joint improves structure and locating ring 4 cancellations can be replaced by hold-down head 2 local crimps.

After using valve rubber, to the susceptibility reduction of bulb center, mechanism element requirement on machining accuracy and installation are adjusted difficulty and are decreased, and provide cost savings.And the whole baffle wall surface is in submissive smooth state at any time, has more increased aesthetic feeling.
