Abstract
The utility model discloses a kind of dowel device, including pin and pin sleeve, the periphery of the pin is provided with the lantern ring for clearing up dust, and the inner sidewall of the pin sleeve is provided with the dustproof groove matched with lantern ring；Beneficial effect is: lantern ring is provided on pin, pin sleeve is provided with dustproof groove, for pin to when being inserted into inside pin sleeve in position fixing process, lantern ring all removes the dust in the inner wall and dustproof groove of pin sleeve, and preventing dust from interfering to pin positioning causes positioning inaccurate.
Description
Technical field
The utility model relates to dowel device technical field more particularly to a kind of dowel devices.
Background technique
At present in many occasions in need to use positioning mechanism, such as sell directly to households formula, the modes such as taper pin formula；Positioning method is most important
Seek to consolidate practical, general positioning device is all to need by being adjacent to mode to contact surface to realize accurate positioning, in this way
Although positioning method it is reliable, at least there are problems that two, it is necessary first to which there is very high dimensional accuracy in mechanism, not enough in fact
With；It is followed by highly susceptible to tiny sundries interference in the actual use environment, mechanism positioning accuracy is caused to be lost.
Utility model content
The technical problem to be solved by the present invention is to provide a kind of dowel device, lantern ring is provided on pin, effectively
Prevent pin dust in positioning from penetrating into pin sleeve.
The technical solution of the utility model are as follows: a kind of dowel device, including pin and pin sleeve, the periphery of the pin
It is provided with the lantern ring for clearing up dust, the inner sidewall of the pin sleeve is provided with the dustproof groove matched with lantern ring.
As a preferred embodiment of the present invention, the material of the lantern ring is soft silica gel.
As a preferred embodiment of the present invention, the outer diameter of the lantern ring is slightly larger than the outer diameter of dustproof groove.
As a preferred embodiment of the present invention, there are two lantern rings, the pin sleeve to be provided with two for setting on the pin
A dustproof groove.
Beneficial effect by adopting the above technical scheme is: the lantern ring that material is silica gel, pin sleeve setting are provided on pin
There is a dustproof groove, pin is to when being inserted into inside pin sleeve in position fixing process, and lantern ring is by the ash in the inner wall and dustproof groove of pin sleeve
Dirt all removes, and preventing dust from interfering to pin positioning causes positioning inaccurate.
Detailed description of the invention
Fig. 1 is that the pin in the utility model enters the front schematic view before pin sleeve；
Fig. 2 is that the pin in the utility model enters the perspective view before pin sleeve；
In figure, 1- pin, 2- pin sleeve, 3- lantern ring, 4- dustproof groove, the inner wall of 5- pin sleeve.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
Referring to Fig. 1,2, a kind of dowel device, including pin 1 and pin sleeve 2, the periphery of pin 1 are provided with for clearing up
The lantern ring 3 of dust, the inner wall 5 of pin sleeve are provided with the dustproof groove 4 matched with lantern ring 3.
In the utility model, pin 1 in positioning towards moving in pin sleeve 2, set on the periphery of pin 1 lantern ring 3 with
The friction removal dust of inner wall 5 of pin sleeve, the inner wall 5 of pin sleeve are additionally provided with dustproof groove 4, dustproof groove 4 rise must buffer and
Auxiliary positioning effect, during the motion, lantern ring 3 is by can also remove the dust in dustproof groove 4 when dustproof groove 4 for pin 1.
The material of lantern ring 3 is soft silica gel, because the better performances of the removal dust of soft silica gel, and generate the model of deformation
Enclose it is larger, pin 1 enter pin sleeve 2 or take out pin sleeve 2 it is all very easy and convenient.
The outer diameter of lantern ring 3 is slightly larger than the outer diameter of dustproof groove 4, can reach preferable dust removing effects, and pin 1 passes in and out pin sleeve
Also facilitate when 2.
There are two lantern rings 3 for setting on pin 1, and there are two dustproof grooves 4 for the setting of pin sleeve 2, this is one of the utility model
Embodiment is under normal circumstances enough removed the dust in pin sleeve 2 with two lantern rings 3 and dustproof groove 4 clean.
The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched
The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit
These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
