Description
Technical field
The utility model relates to a kind of track-type facilities, especially relates to a kind of track-type facilities of energy noise reducing dust.
Background technology
The track-type facilities of existing sliding door or window, the hollow guide-track groove of many employings, when sliding door or window when this slides above track-type facilities, larger friction can occur with guide rail in pulley, the sound that sends is larger, and extraneous dust and foreign material also are easy to enter in the described guide-track groove, are unfavorable for cleaning, also affect the attractive in appearance and sliding door of guide rail or the sliding effect of window simultaneously.
Summary of the invention
Based on this, the utility model is to overcome the defective of prior art, and a kind of track-type facilities is provided, and it has the function of noise reducing dust.
Its technical scheme is as follows:
A kind of track-type facilities, comprise mounting base, described mounting base is provided with guide-track groove, described guide-track groove is provided with notch, this track-type facilities also includes the noise reducing dust bar, described noise reducing dust bar is made by elastomeric material, and this noise reducing dust bar is installed in the described guide-track groove, and props up the notch of guide-track groove.
The below describes further technical scheme:
The notch of described guide-track groove is less than the groove body.
Described noise reducing dust bar includes base and along noise reducing dust bar protuberance longitudinally, described protuberance is located at above the base, and described base matches with the groove body of guide-track groove, and described protuberance matches with the notch of guide-track groove.
Described protuberance is provided with along noise reducing dust bar groove longitudinally.
Described base and protuberance are connected as a single entity, and inner hollow.
The cross section of described noise reducing dust bar is " protruding " font.
A kind of track-type facilities, comprise mounting base, described mounting base is provided with guide-track groove, described guide-track groove is provided with notch, and described notch also is equipped with pulley, and this track-type facilities also includes the noise reducing dust bar, described noise reducing dust bar is made by elastomeric material, this noise reducing dust bar is installed in the described guide-track groove, and props up the notch of guide-track groove, and described pulley is against on the described noise reducing dust bar.
The below describes advantage or the principle of aforementioned techniques scheme:
1, described track-type facilities, its noise reducing dust bar is made by elastomeric material, and be installed in the guide-track groove of mounting base, prop up the notch of guide-track groove, when pulley being arranged when this track-type facilities slides, pulley is against above the noise reducing dust bar, because the carrying of noise reducing dust bar has been arranged, pulley weakens greatly with the friction of guide-track groove generation when sliding, thereby played the effect of noise reduction, the noise reducing dust bar also is against on the notch of guide-track groove on the other hand, and therefore extraneous dust and foreign material just can not enter in the guide-track groove by this notch, has then played again dustproof effect.
2, described notch facilitates at notch like this pulley is installed less than the groove body.
3, described noise reducing dust bar is provided with base and protuberance, and its cross section is " protruding " font, because base matches with the groove body, protuberance matches with notch, this protuberance has also occupied notch simultaneously, so just stoped extraneous dust and foreign material to enter in the guide-track groove by notch, and so that the friction that occurs between pulley and the guide-track groove greatly weaken, thereby also played the effect of noise reduction.
4, described protuberance also is provided with groove, and pulley just is against in this groove, thereby is conducive to the superincumbent slip of pulley.
5, described base and protuberance are connected as a single entity, and inner hollow, thereby have saved material, have reduced cost.

The specific embodiment
The below is elaborated to embodiment of the present utility model:
Such as Fig. 1-3, a kind of track-type facilities, comprise mounting base 1, described mounting base 1 is provided with two guide-track grooves 2 concurrently, described guide-track groove 2 is provided with notch 3, in described guide-track groove 2 noise reducing dust bar 4 is installed, described noise reducing dust bar 4 is made by elastomeric material, and this noise reducing dust bar 4 props up the notch 3 of guide-track groove 2.
Wherein, the notch 3 of guide-track groove 2 is less than the groove body, noise reducing dust bar 4 includes base 403 and along noise reducing dust bar 4 protuberance 401 longitudinally, this protuberance 401 is located at above the base 403, and base 403 matches with the groove body of guide-track groove 2, protuberance 401 matches with the notch 3 of guide-track groove 2, base 403 and protuberance 401 are connected as a single entity, inner hollow, and its cross section is " protruding " font, in addition, above-mentioned protuberance 401 also is provided with along noise reducing dust bar 4 groove 402 longitudinally.
Further, at notch 3 pulley 5 is installed also, described pulley 5 is against on the above-mentioned noise reducing dust bar 4.
The below describes advantage or the principle of aforementioned techniques scheme:
1, described track-type facilities, its noise reducing dust bar 4 is made by elastomeric material, and be installed in the guide-track groove 2 of mounting base 1, prop up the notch 3 of guide-track groove 2, when pulley 5 being arranged when this track-type facilities slides, pulley 5 directly is against above the noise reducing dust bar 4, because the carrying of noise reducing dust bar 4 has been arranged, pulley 5 when sliding and the friction that occurs of guide-track groove 2 greatly weaken, thereby played the effect of noise reduction, noise reducing dust bar 4 also is against on the notch 3 of guide-track groove 2 on the other hand, and therefore extraneous dust and foreign material just can not enter in the guide-track groove 2 by this notch 3, has then played again dustproof effect.
2, described notch 3 facilitates like this at notch 3 pulley 5 is installed less than the groove body.
3, described noise reducing dust bar 4 is provided with base 403 and protuberance 401, and its cross section is " protruding " font, because base 403 matches with the groove body, protuberance 401 matches with notch 3, protuberance 401 has also occupied notch 3 simultaneously, so just stoped extraneous dust and foreign material to enter in the guide-track groove 2 by notch 3, and so that the friction of pulley 5 and guide-track groove 2 greatly weaken, thereby also played the effect of noise reduction.
4, described protuberance 401 also is provided with groove 402, and pulley 5 just is against in this groove 402, thereby is conducive to pulley 5 superincumbent slips.
5, described base 403 and protuberance 401 are connected as a single entity, and inner hollow, thereby have saved material, have reduced cost.
The above embodiment has only expressed the specific embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
