Description
Technical Field
The invention belongs to the field of floor springs, and particularly relates to a floor spring assembly with a buffering function.
Background
The floor spring is a hydraulic door closer, except that the device for pressing the spring is a worm wheel instead of a gear and a rack. Because the worm wheel can rotate in the forward and reverse directions, the floor spring can be used for a door which is opened in both directions, and the door closer can be used for a door which is opened in only one direction. The basic configuration of the ground springs is the upper and lower (or ground) axes. The upper part of the upper shaft is connected with a door frame and a door leaf, and consists of a bolt-adjustable shaft fixed on the door leaf and a shaft sleeve fixed on the door leaf. The paraxial and geodesic shaft may be adapted for use with almost all wooden, steel, aluminum alloy doors and borderless glass doors using glass door clamps.
Glass doors with floor springs mounted thereon are often transparent and can be bumped by unnoticed persons, resulting in damage to the glass door, person, object, or floor spring. People who enter and exit the glass door of many storefronts or shops can be attracted by pasting warning marks, but the warning effect is poor due to the limited area of the warning marks.
The invention designs a floor spring assembly with a buffering function, which solves the problem that a glass door, people, objects and a floor spring are damaged when the glass door provided with the floor spring is impacted.

The floor spring 27 of the present invention is of the prior art.
The working flow of the invention is as follows: in the initial state, the glass door 2 is in a closed state, the swing limiting block 14 in the upper spring mechanism 3 is positioned at the limit position of one end of the swing groove 8, the clamping block 16 is positioned in the clamping groove 13, the pressing spring 17 is in a compressed state, the connecting rod 21 is horizontally parallel to the glass door 2, and the rotating shaft A22 is in a vertical state. The rotation axis C30 in the lower spring mechanism 26 is in a vertical state.
When the glass door 2 provided with the invention is normally opened or closed, the moment generated by the acting force of the glass door 2 when the glass door is opened or closed is insufficient to overcome the elasticity of the pressing spring 17 in the upper spring mechanism 3, so that the upper end of the glass door 2 rotates relative to the inner shell 5 through the corresponding U-shaped clamping sleeve 23, the rotating shaft A22, the connecting rod 21 connected with the rotating shaft A22 in a spherical hinge manner, the annular sleeve B19 and the square shaft 18, and therefore, during the normal opening or closing process of the glass door 2 under the normal acting force, the upper end of the glass door 2 drives the rotating shaft A22 to rotate relative to the connecting rod 21 hinged with the rotating shaft A22 around the center axis of the rotating shaft A22 through the corresponding U-shaped clamping sleeve 23, the rotating shaft C30 and the rotating shaft B28 in the ground spring 27 through the corresponding U-shaped clamping sleeve 29. At this time, the glass door 2 is opened or closed about the center axis of the rotation shaft a22 and the rotation shaft B28, and the lower spring mechanism 26 functions as a conventional floor spring 27.
When the door surface of the glass door 2 provided with the invention is impacted by people or objects suddenly because of the carelessness or the intention of people entering and exiting the door, the moment generated by the impact force borne by the glass door 2 is enough to overcome the elastic force of the pressing spring 17 in the upper spring mechanism 3, so that the glass door 2 drives the annular sleeve A9 to rotate relative to the inner shell 5 through the rotating shaft A22, the connecting rod 21 connected with the rotating shaft A22 in a spherical hinge manner, the annular sleeve B19 and the square shaft 18, and the glass door 2 swings for relieving collision impact around the connection line between the hinge point of the U seat 20 and the annular sleeve B19 and the inclined center of the cross universal joint 29 in the lower spring mechanism 26.
In the swing process of the glass door 2 for relieving collision impact by the connection line between the hinging point of the U seat 20 and the ring sleeve B19 and the inclined center of the cross universal joint 29 in the lower spring mechanism 26, the glass door 2 drives the ring sleeve A9 to rotate relative to the inner shell 5 by overcoming the propping pressure of the propping spring 17 through the rotating shaft A22, the connecting rod 21 connected with the rotating shaft A22 in a spherical hinge mode, the U seat 20, the ring sleeve B19 and the square shaft 18, a clamping block 16 arranged on the sliding block 15 instantaneously slides out of a clamping groove 13 on the driving groove 11, the clamping block 16 drives the sliding block 15 to shrink inwards towards the sliding groove 7 under the action of a driving cambered surface 12 with the radius gradually increased from the middle part to the two sides on the driving groove 11, the propping spring 17 is further compressed, and the ring sleeve A9 drives the swing limiting block 14 to swing in the swinging groove 8.
In the swing process of the glass door 2 for relieving collision impact by winding the hinging point of the U seat 20 and the ring sleeve B19 and the inclined central connecting line of the cross universal joint 29 in the lower spring mechanism 26, the lower end of the glass door 2 for relieving collision impact swing by winding the hinging point of the U seat 20 and the ring sleeve B19 and the inclined central connecting line of the cross universal joint 29 in the lower spring mechanism 26 drives the cross universal joint 29 to perform universal torsion through the corresponding U-shaped clamping sleeve 23 and the rotating shaft C30, and the cross universal joint 29 drives the rotating shaft B28 of the ground spring 27 in the lower spring mechanism 26 to rotate, so that the lower spring mechanism 26 still plays the function of the traditional ground spring 27. However, since the moment about the hinge point of the collar B19 and the U-seat 20 and the oblique line of the center of the cross-shaped universal joint 29 in the lower spring mechanism 26 and the moment about the force applied to the collision point of the glass door 2 are larger than the moment between the force applied to the collision point of the glass door 2 and the upper rotating shaft B28 of the ground spring 27, the impact shock applied to the glass door 2 about the hinge point of the collar B19 and the U-seat 20 and the oblique line of the center of the cross-shaped universal joint 29 in the lower spring mechanism 26 can be effectively buffered, and the impact shock damage of the glass door 2, the person, the ground spring 27 and the object can be effectively reduced or avoided.
When the glass door 2 is reset after being impacted violently, the glass door 2 which is buffered and swung by the hand around the hinging point of the ring sleeve B19 and the U seat 20 and the inclined connecting line of the center of the cross universal joint 29 in the lower spring mechanism 26 swings back and resets around the hinging point of the ring sleeve B19 and the U seat 20 and the inclined connecting line of the center of the cross universal joint 29 in the lower spring mechanism 26.
In the process of swinging back and resetting the glass door 2 around the hinging point of the ring sleeve B19 and the U seat 20 and the inclined connecting line of the center of the cross universal joint 29 in the lower spring mechanism 26, the glass door 2 drives the ring sleeve A9 to reversely rotate relative to the inner shell 5 through the rotating shaft A22, the connecting rod 21 which is in spherical hinge connection with the rotating shaft A22, the U seat 20, the ring sleeve B19 and the square shaft 18, and the clamping block 16 arranged on the sliding block 15 slides towards the clamping groove 13 on the driving groove 11 along the driving cambered surface 12 on the driving groove 11. Under the combined action of the driving cambered surface 12 and the pressing spring 17, the clamping block 16 drives the sliding block 15 to move outwards of the sliding groove 7, the pressing spring 17 releases energy, and the loop A9 drives the swing limiting block 14 to swing back in the swing groove 8.
When the glass door 2 is reset, the clamping block 16 reenters the clamping groove 13 under the action of the pressing spring 17.
In the process of swinging back and resetting the glass door 2 around the hinging point of the ring sleeve B19 and the U seat 20 and the inclined connecting line of the center of the cross universal joint 29 in the lower spring mechanism 26, the lower end of the glass door 2 which swings back and resets around the hinging point of the ring sleeve B19 and the U seat 20 and the inclined connecting line of the center of the cross universal joint 29 in the lower spring mechanism 26 drives the cross universal joint 29 to perform universal resetting torsion through the corresponding U-shaped clamping sleeve 23 and the rotating shaft C30, and the cross universal joint 29 drives the rotating shaft B28 of the ground spring 27 to reversely rotate and reset. When the glass door 2 is completely reset, the rotating shaft A22, the rotating shaft B28 and the rotating shaft C30 are positioned in the concentric axis again.
In summary, the beneficial effects of the invention are as follows: in the invention, when the glass door 2 in a closed state is impacted violently, the upper spring mechanism 3 playing a traditional crown role in the normal opening and closing process of the glass door 2 and the lower spring mechanism 26 playing a traditional crown role in the normal opening and closing process of the glass door 2 can enable the glass door 2 to generate buffer swing around the hinging point of the ring sleeve B19 and the U seat 20 and the inclined connecting line of the center of the cross universal joint 29 in the lower spring mechanism 26. Because the moment about the hinge point of the loop B19 and the U seat 20 and the moment about the force applied to the impact point of the glass door 2 by the inclined connection line of the center of the cross universal joint 29 in the lower spring mechanism 26 are greater than the moment between the force applied to the impact point of the glass door 2 and the rotating shaft B28 on the ground spring 27, the buffer swing of the glass door 2 about the hinge point of the loop B19 and the U seat 20 and the inclined connection line of the center of the cross universal joint 29 in the lower spring mechanism 26 can effectively buffer the impact applied to the glass door 2 when the glass door 2 is subjected to a violent impact, thereby effectively reducing or avoiding the impact damage of the glass door 2, the person, the ground spring 27 and objects.
