In order to solve the problems in the prior art, the invention provides an angle-adjustable universal rolling structure, which utilizes an elastic body to connect and support a base and a rolling body, so that when the rolling body is impacted, the deformation of the elastic body is utilized to change the swinging angle of the rolling body relative to the base, the elastic body resets after the impact is buffered and supports the rolling body to return, and the swinging angle of the rolling body relative to the base is recovered. The shock resistance of the rolling body is increased, the collision damage of the rolling body is reduced, and the problems in the prior art are solved.
The technical scheme adopted by the invention is as follows:

Further, the elastomer is a polyurethane elastomer. The elastomer made of polyurethane has elasticity and high hardness, so that the elastomer can better connect the rolling seat with the base and support the rolling seat and the base. Moreover, the elastic body does not need to adopt structures such as hydraulic pressure and the like, and is pollution-free and environment-friendly.
Further, the elastomer is corrugated. At the initial stage of the rolling body swinging relative to the base, hereinafter referred to as the initial stage of swinging, the corrugated section is folded and deformed, so that a good buffering function is brought; in the later period of the rolling body swinging relative to the base, hereinafter referred to as the swinging later period, the corrugated sections mainly play a role of elastic deformation support when being pressed and contacted.
Furthermore, the elastic body comprises a first connecting part, a second connecting part and a deformation part, the rolling body forms a first connecting end at the end part close to the rolling seat, the first connecting part is connected with the first connecting end, the base forms a second connecting end at the end part close to the mounting end, the second connecting part is connected with the second connecting end, a deformation space is formed between the first connecting end and the second connecting end, and the deformation space can accommodate the deformation part to deform when the rolling seat rotates relative to the mounting end. With this structure, the elastic body has enough space to elastically deform, and the connection between the elastic body and the rolling body and the base is firm.
Further, the base forms an inclined surface facing the second connection portion between the mounting end and the second connection end, or the rolling body forms an inclined surface facing the first connection portion between the rolling seat and the first connection end. Therefore, the inclined plane plays a guiding role, the elastic body can better elastically deform along the inclined plane, and in addition, when the inward deformation part of the elastic body is in contact with the inclined plane, a certain supporting force is formed, so that the rolling body can be effectively supported and restrained in the later period of swinging.
Further, the elastic body is of a double-arc cylindrical structure, and the inner surface and the outer surface of the elastic body are both concave towards the inside. Therefore, the elastic body can be more easily and effectively elastically deformed by taking the arc-shaped structure as a guide so as to effectively buffer the impact force applied to the rolling body by the rolling body.
Furthermore, the installation end is a rotary sphere sleeved on the base, and the rolling seat is rotatably connected with the rotary sphere. By the structure, the swing between the mounting end and the rolling seat is more flexible, the connection is more firm, the rolling body is impacted to stop impacting, the mounting end and the rolling seat can both deform to the flexible relative swing in the recovery process of the elastic body, and the rolling seat is not easy to separate from the mounting end.

Furthermore, at least part of the rolling body is positioned in the mounting groove, a gap is formed between the side surface of the rolling body and the groove wall of the mounting groove, and the mounting structure with the adjustable ball angle further comprises an elastic filling body filled in the gap. Therefore, the elastic filling body plays a role in sealing, and prevents foreign matters from entering a region between the elastic body and the mounting groove and hindering the deformation of the elastic body; the elastic filling body also plays a role in pre-tightening and supporting, so that the rolling body is more firmly connected with the mounting groove, and the rolling body is kept in place in a normal state.
Furthermore, the elastic filling body extends to the side of the elastic body, and the hardness of the elastic filling body is smaller than that of the elastic body. Thus, first, the rolling elements have sufficient elastic space to deflect; secondly, the elastic filling body is cooperated with the elastic body to deform at the initial swinging stage and is recovered after the swinging stage, so that the whole process is stable and layered; and thirdly, the elastic filling body can play a role in buffering at the initial swinging stage and can play a role in supporting and protecting at the later swinging stage.

According to the invention, the angle of the rolling body 2 relative to the base 1 is adjusted by utilizing the deformation of the elastic body 3, so that the impact on the rolling body 2 is buffered, the rolling property of the rolling body 2 is not changed in the whole process, the impact resistance of the rolling body 2 is increased, the collision and failure conditions of the rolling body 2 are reduced, particularly in some rolling environments with concave-convex fluctuation on the surface side, the rolling body 2 has a better vibration reduction effect, and the damage and failure of the rolling body 2 caused by frequent larger transverse impact force are reduced. In addition, the elastic body 3 surrounds and seals the space between the mounting end 11 and the rolling seat 21, so that the swinging space between the mounting end 11 and the rolling seat 21 is effectively sealed, foreign matters can be prevented from entering, the cleanness of the rotating connection between the mounting end 11 and the rolling seat 21 is kept, and the rolling body 2 can stably swing.
Specifically, the elastomer 3 is a polyurethane elastomer 3. The elastic body 3 made of polyurethane has elasticity and high hardness, so that the elastic body 3 can better connect the rolling seat 21 with the base 1 and support the rolling seat 21 with the base 1. Moreover, the elastic body 3 does not need to adopt structures such as hydraulic pressure and the like, and is pollution-free and environment-friendly. Besides, in other embodiments, the elastic body 3 may be rubber, spring, or other elastic material or structure.
As shown in fig. 1 to 3, the elastic body 3 is corrugated. In the initial stage of the rolling body 2 swinging relative to the base 1, hereinafter referred to as the initial stage of swinging, the corrugated section is folded and deformed, so that a good buffering function is brought; in the later period of the rolling body 2 swinging relative to the base 1, hereinafter referred to as the swinging later period, the corrugated sections mainly play the role of elastic deformation support when being pressed and contacted. In addition, with the structure, firstly, the deformability of the elastic body 3 is more flexible, and after the rolling body 2 is impacted, the elastic body 3 can quickly respond to the impact to deform, so that the situations that the rolling body 2 is damaged and fails under the impact due to slow deformation of the elastic body 3 are avoided; secondly, the elastic body 3 has good ductility, and the whole stress is relatively uniform when the elastic body 3 is deformed, so that the elastic body 3 is not broken by repeatedly performing excessive deformation on a certain part compared with other parts when the elastic body 3 is deformed, and the elastic body 3 is more durable.
As shown in fig. 1 to 3, the elastic body 3 includes a first connection portion 31, a second connection portion 32 and a deformation portion 33, the rolling body 2 forms a first connection end 23 at an end portion close to the rolling seat 21, the first connection portion 31 is connected with the first connection end 23, the base 1 forms a second connection end 13 at an end portion close to the mounting end 11, the second connection portion 32 is connected with the second connection end 13, a deformation space 34 is formed between the first connection end 23 and the second connection end 13, and the deformation space 34 can accommodate the deformation portion 33 to deform when the rolling seat 21 rotates relative to the mounting end 11. With this structure, the elastic body 3 has a sufficient space to be elastically deformed, and the connection with the rolling body 2 and the base 1 is secured.
Specifically, the elastic body 3 and the rolling body 2 or the base 1 can be integrally cast or bonded and the like to be integrally fixed, so that the installation steps are saved, and the elastic body 3 and the rolling body 2 or the base 1 can be prevented from being installed unreliably in the working process, so that the elastic body and the rolling body move relative to each other or even are separated from each other in the working process.
Preferably, as shown in fig. 1 to 3, the base 1 forms a slope 14 between the mounting end 11 and the second connection end 13 toward the second connection portion 32. Therefore, in the initial period of the swing, the inclined surface 14 is arranged so that the direction of the interaction force between the first connecting end 23 and the first connecting portion 31 is along the inclined surface 14, so that the deformation portion 33 is guided and compressed along the impact direction, and the process is stable, reliable and layered, thereby effectively buffering the impact on the rolling element 2; in the later period of the swinging, a certain supporting force is formed when one side of the deformation part 33 which is compressed and deformed inwards is deformed to be in contact with the inclined surface 14 and extruded, the larger the contact area of the deformation part 33 and two surfaces at the upper side and the lower side is, the smaller the deformation space 34 of the deformation part 33 provided by the gap is, so that the supporting force which can be provided by the deformation part 33 is larger and larger, and the rolling body 2 can be effectively supported and restrained; at the end of the impact, the supporting force and the tensile force of the other side which is subjected to tensile deformation provide the restoring force when the rolling bodies 2 are restored, and the direction of the interaction force of the first connecting end 23 and the first connecting part 31 is along the inclined surface 14, the tensile force of the side which is subjected to tensile deformation by the deformation part 33 on the rolling bodies 2 is guided, so that the restoring process is stable, reliable and layered. The inclined surface 14 may be formed between the mounting end 11 and the second connection end 13 of the base 1, or the rolling elements 2 may be formed between the rolling seat 21 and the first connection end 23, and the inclined surface 14 faces the first connection portion 31. It should be further emphasized that the above description of the orientation, direction, etc. is made for the convenience of referring to the drawings and should not be construed as limiting the present application.
In addition, as shown in fig. 4, the elastic body 3 may also have a double-arc cylindrical structure in which both the inner surface and the outer surface are recessed inward. Thus, the elastic body 3 is more easily elastically deformed to effectively cushion the rolling elements 2 against the impact force based on the above effects by the arc-shaped structure as a guide and the provision of the inclined surface 14.
As a further optimization of the rotational connection between the mounting end 11 and the rolling seat 21, as shown in fig. 1-3, the mounting end 11 is a rotary sphere sleeved on the base 1, and the rolling seat 21 is rotationally connected with the rotary sphere. By the structure, the installation end 11 and the rolling seat 21 swing more flexibly and are connected more firmly, the rolling body 2 is impacted and stops impacting, the installation end 11 and the rolling seat 21 can swing flexibly and relatively in the process that the elastic body 3 deforms and recovers, and the rolling seat 21 is not separated from the installation end 11 easily. The rotational connection between the mounting end 11 and the rolling seat 21 may be any rotational structure known to those skilled in the art.
As shown in fig. 5, the present invention further provides a ball angle-adjustable mounting structure, which includes a base 1, a rolling element 2, an elastic body 3, and a base 4, wherein the base 1 includes a mounting end 11 and a fixing end 12; the rolling body 2 comprises a rolling seat 21 rotationally connected with the mounting end 11 and a rolling part 22 arranged on one side of the rolling seat 21 far away from the base 1; the elastic body 3 is connected with the base 1 and the rolling seat 21, the elastic body 3 surrounds and seals a space between the mounting end 11 and the rolling seat 21, and the elastic body 3 deforms when the rolling seat 21 rotates relative to the mounting end 11 so as to provide a force for resetting the rolling seat 21; the base 4 has a mounting groove 41, the base 1 is mounted to the mounting groove 41 in the mounting direction, and the rolling portion 22 protrudes out of the base 4.
As shown in fig. 5, the rolling body 2 is at least partially positioned in the mounting groove 41, and a gap is formed between the side surface of the rolling body 2 and the wall of the mounting groove 41, and the ball angle adjustable mounting structure further includes an elastic filling body 5 filled in the gap. First, the elastic filling body 5 plays a role of sealing, as shown in fig. 6, when the elastic body 3 deforms, a gap is formed between the side that undergoes inward expansion deformation and the mounting groove 41, and at this time, foreign matters may enter the gap, and in the past, the foreign matters are accumulated, the elastic body 3 is limited in deformation and recovery, and therefore, the swing is limited, the elastic filling body 5 is arranged so that the gap between the elastic body 3 and the mounting groove 41 when the elastic body 3 deforms is filled, and due to the elasticity of the elastic filling body, the elastic filling body 3 does not have adverse effects on the deformation and recovery of the elastic body 3, and the foreign matters are effectively prevented from entering the gap between the elastic body 3 and the mounting groove 41; secondly, the elastic filling body 5 plays a role in pre-tightening and supporting, and due to the elastic filling, the pre-tightening force is applied to the rolling body 2 and the mounting groove 41, so that the rolling body 2 and the mounting groove 41 are more tightly and firmly connected and are not easy to separate, and the rolling body 2 can be kept in place in a normal state and cannot easily swing. It should be noted that in an exemplary embodiment as shown in fig. 5, the notch of the mounting groove 41 is enlarged, the cross-sectional profiles of the rolling element 2 and the base 1 are substantially the same, and in other embodiments, the matching may be the same as the contour of the mounting groove 41, the cross-sectional profile of the rolling element 2 is smaller than the cross-sectional profile of the base 1, or other matching structures with the same function.
