Also referring to Fig. 1 to Fig. 3 and Fig. 7, the damping shock absorption universal caster wheel now provided the utility model embodiment enters Row explanation.

The telescoping mechanism that the damping shock absorption universal caster wheel that the utility model embodiment provides includes wheel body 1, is connected with wheel body 1 And the rotating mechanism being connected with telescoping mechanism;Wherein, telescoping mechanism include can relative axial movement telescopic shaft 2 and be arranged Telescopic stand 3 in the periphery of telescopic shaft 2, telescopic shaft 2 stretch between the part of telescopic stand 3 and the inwall of telescopic stand 3 and form cushion chamber Body;The buffering cavity includes the first cavity 41 being axially distributed and the second cavity (inconvenience is shown in figure) along telescopic stand 3, its In the first cavity 41 close to the top of telescopic stand 3, in the bottom of telescopic stand 3, the present embodiment, castor is positioned over the second cavity Its position away from ground is upper during ground, under the position close to ground is.It is provided with first cavity 41 and is used to buffer telescopic shaft 2 The spring 5 moved axially with telescopic stand 3, and the first cavity 41 and the second cavity inner wall scribble damping grease, it will be understood that should The end that one end of spring 5 gos deep into telescopic stand 3 with telescopic shaft 2 is directly or indirectly connected, the other end then for free end or with The top of telescopic stand 3 directly or indirectly abuts, allow the spring 5 when telescopic shaft 2 and telescopic stand 3 relatively move by Compression or stretching, and then produce the violent relative motion that elastic force is used to buffer telescopic shaft 2 and telescopic stand 3.In addition, the telescopic shaft 2 It is further opened with connecting the stomata 6 of the first cavity 41 and the second cavity.The cavity of first cavity 41 and second forms piston structure, when Strenuous vibration occurs for wheel body 1, causes telescopic shaft 2 and when very fast relative movement by a relatively large margin occurs for telescopic stand 3, the first cavity 41 Interior gas is compressed, and the second cavity is flowed into by stomata 6, and is slowly flowed back while telescopic shaft 2 is extracted out, with gas Throttle Principle, air mass flow is controlled, the effect of different damping shock absorptions can be produced, by adjusting the size of stomata 6 to adapt to more Extensive load request.

The damping shock absorption universal caster wheel that the utility model embodiment provides, the telescopic shaft 2 and telescopic stand 3 of its telescoping mechanism it Between form the buffering cavity including the first cavity 41 and the second cavity, spring 5 is provided with the first cavity 41, in cushion chamber Internal wall scribbles damping grease, can effectively buffer the relative axial movement of telescopic shaft 2 and telescopic stand 3, gas is opened up on telescopic shaft 2 Hole 6 connects the first cavity 41 and the second cavity, forms piston structure, and with gas throttling principle, control air mass flow produces not The effect of same damping shock absorption.Therefore, the damping shock absorption universal caster wheel can not only be realized by rotating mechanism and freely rotated, also With more preferable damping effect, transmitting workpiece is protected, and reduces the dust amount of kicking up, is expected to improve the workpiece under dustfree environment requirement Qualification rate, realize stable platform movement effect.

With further reference to Fig. 7, telescopic shaft 2 includes the first narrow shaft part 21, the wide shaft part 22 and second of integrally connected successively Narrow shaft part 23, the first narrow shaft part 21 are located in the first cavity 41, and spring 5 is sheathed on the first narrow shaft part 21;Wide shaft part 22 is with stretching The inwall of seat 3 slides fitting, buffering cavity is divided into the first cavity 41 and the second cavity, while also spring 5 is sheathed on By the end abutment of wide shaft part 22 while first narrow shaft part 21;Second narrow shaft part 23 portion with the axial movement of telescopic shaft 2 Divide or all expose.When telescopic shaft 2 stretches into telescopic stand 3, the second narrow shaft part 23 is more to be located in the second cavity, works as telescopic shaft 2 when skidding off telescopic stand 3, and the second narrow shaft part 23 is most of to be externally exposed.

Further, the diameter of the first narrow shaft part 21 is less than the diameter of wide shaft part 22, and the diameter of the second narrow shaft part 23 is less than The diameter of wide shaft part 22, the diameter of the first narrow 21 and second narrow shaft part 23 of shaft part can be with unlimited.In the present embodiment, preferably first The diameter of narrow shaft part 21 is less than the diameter of the second narrow shaft part 23 so that the space of the first cavity 41 is bigger, and the sky of the second cavity Between be mainly used in the first cavity 41 carry out gas circulation, its space can be with smaller.

Further, can be arranged such that for connecting the stomata 6 of the first cavity 41 and the second cavity, from the first narrow shaft part 21 end face opens up and extends inwardly to form axial stomata 61, further forms radial direction stomata perpendicular to the extension of axial stomata 61 62, and radial direction stomata 62 leads to the second cavity.The effect of different damping shock absorptions can be produced by adjusting the size of axial stomata 61 Fruit, to adapt to wider load request.

With further reference to Fig. 4 and Fig. 7, in order to limit the shift motion of telescopic shaft 2, in telescopic stand 3 close to the second narrow shaft part Back-up ring 7 is provided with 23 end face, the shape and the end surface shape of telescopic stand 3 of the back-up ring 7 are adapted, usually annular, gear The internal diameter of circle 7 is consistent with the diameter of the second narrow shaft part 23, and the internal diameter of such back-up ring 7 is less than the diameter of wide shaft part 22, can limit The axial stroke of telescopic shaft 2, prevent telescopic shaft 2 from skidding off telescopic stand 3 from lower section.Also, the inwall of back-up ring 7 and the second narrow shaft part 23 Unanimously so that close connection therebetween, so in back-up ring 7, the lower end of wide shaft part 22, the inwall of telescopic stand 3 and the second narrow shaft part The second cavity more sealed is formd between 23 outer wall.

One kind as the present embodiment is improved, and through hole 31 is offered close to one end of the first cavity 41 in telescopic stand 3, is such as schemed 3, the pad 8 be connected with the end of spring 5 is provided with the first cavity 41 at face through hole 31, using an adjustment jackscrew 9 through leading to Hole 31 is simultaneously connected to pad 8, using the fixed adjustment jackscrew 9 of the fixtures such as nut 10, and can adjust the adjustment jackscrew 9 and stretch into Length in first cavity 41, and then the largest deformation amount of spring 5 can be adjusted, and then change the size in damping space.Specifically Ground, when rotating nuts move down adjustment jackscrew 9, between adjustment jackscrew 9 and spring 5 and the connection end of telescopic shaft 2 Contraction in length, its deformation quantity diminish, and damping space diminishes, otherwise deformation quantitative change is big, the increase of damping space.

With further reference to Fig. 4, for the ease of adjusting the regulation of jackscrew 9, groove 81 is set on pad 8, for spacing appearance Receive the end of adjustment jackscrew 9, and then avoid adjusting jackscrew 9 and slide with respect to pad 8.

Further, the external diameter of pad 8 is consistent with the internal diameter of the first cavity 41 so that the first cavity 41 seals as far as possible, prevents Only pass through the gas leakage of through hole 31 at the top of telescopic stand 3.
