Abstract
The utility model discloses a kind of quick-replaceable shaft device, comprise symmetrically arranged two supports, described support comprises base, limit stoper and roller, cavity is symmetrically arranged with in the two side of described base, limit stoper is provided with in described cavity, described limit stoper comprises position-limited lever, limiting board and spring, and described position-limited lever runs through by spring, and described spring is arranged between limiting board and cavity inner wall.The inside lower end of described base is symmetrically arranged with two rollers; The utility model can quick-replaceable when axle deforms or rupture, and adds manufacturing efficiency, saves and repairs be artificial, save material, save cost, be easy to promote the use of.
Description
Technical field
The utility model relates to mechanical field, particularly relates to a kind of quick-replaceable shaft device.
Background technique
In textile manufacturing machine, often use drive mechanism in a large number, and traditional axle can only be installed on bearing, in use, if axle is subject to external impacts distortion, or damaging and ruptured, must take machine apart and place under repair, is not very high and larger to the specific consumption of axle occasion at some to precision, with bearing be fixed up use just not very convenient, particularly printer field, often need more change of lap film, dismounting is time-consuming takes a lot of work, inefficiency, very inconvenient during use, all to unload the parts such as lower bearing at every turn, cannot increase yield.
Model utility content
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of quick-replaceable shaft device, can realize quick-replaceable axle, increases manufacturing efficiency, convenient and swift, saves time, and is easy to promote.
For achieving the above object, the utility model proposes a kind of quick-replaceable shaft device, comprise symmetrically arranged two supports, described support comprises base, limit stoper and roller, be symmetrically arranged with cavity in the two side of described base, be provided with limit stoper in described cavity, described limit stoper comprises position-limited lever, limiting board and spring, described position-limited lever runs through by spring, and described spring is arranged between limiting board and cavity inner wall.The inside lower end of described base is symmetrically arranged with two rollers.
As preferably, described base is arranged to U-groove bevel structure, and one end of described u shape groove is higher than the other end 5 ~ 20 millimeters.
As preferably, described position-limited lever and the integrated setting of limiting board.
The beneficial effects of the utility model: the utility model can quick-replaceable when axle deforms or rupture, and adds manufacturing efficiency, save and repair be artificial, save material, save cost, be easy to promote the use of.
Accompanying drawing explanation
Fig. 1 is schematic perspective view of the present utility model.
Fig. 2 is side view complete section of the present utility model intention.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
A kind of quick-replaceable shaft device as shown in Figure 1, comprise symmetrically arranged two supports 1, described support 1 comprises base 1.1, limit stoper 1.2 and roller 1.3, cavity is symmetrically arranged with in the two side of described base 1.1, limit stoper 1.2 is provided with in described cavity, as shown in Figure 2, described limit stoper 1.2 comprises position-limited lever 1.2.1, limiting board 1.2.3 and spring 1.2.2, described position-limited lever 1.2.1 runs through by spring 1.2.2, and described spring 1.2.2 is arranged between limiting board 1.2.3 and cavity inner wall.The inside lower end of described base 1.1 is symmetrically arranged with two rollers 1.3.Described base 1.1 is arranged to U-groove bevel structure, and one end of described u shape groove is higher than the other end 5 ~ 20 millimeters.Described position-limited lever 1.2.1 and the integrated setting of limiting board 1.2.3.
Wherein, described roller 1.3 is connected with base 1.1 by bearing pin, realizes the effect holding up axle 2 rolling.
In use, axle 2 is put into the U-groove bevel of base 1.1, spring 1.2.2 shrinks position-limited lever 1.2.1 and retreats, and axle 2 enters U-groove bevel, spring 1.2.2 resilience, and position-limited lever 1.2.1 return blocks axle 2, and when needs change axle 2 by position-limited lever 1.2.1 post-tensioning, axle 2 takes out.Cell body is arranged to one high and one low, is not easy slippage during installation shaft 2, is lowly arranged with two rollers 1.3 for reducing frictional force, and axle 2 can Free-rolling.The utility model can quick-replaceable when axle deforms or rupture, and adds manufacturing efficiency, saves and repairs be artificial, save material, save cost, be easy to promote the use of.
Described is preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
