Abstract

A kind of retractable door, comprise many columns that are arranged side by side in regular turn and be installed between the two adjacent upright some the expansion links of cross arrangement in twos, the middle part of two expansion links that wherein intersect flexibly connects by pivot pin, and its characteristics are to be with on the described pivot pin pivot pin cover of being made by nylon or plastics or other nonmetals with shockproof noise reduction effect.The utility model owing to adopt is with the structure of the pivot pin cover of being made by nylon or plastics or other nonmetals on pivot pin, can prevent effectively that direct friction produces vibrations and noise between pivot pin and the expansion link; Owing between the interface of two expansion links that intersect, be provided with the pad of making by nylon or plastics or other nonmetals, direct friction produces vibrations and noise between two expansion links that can further prevent to intersect, the utility model not only can the unit of being used in front door, also applicable to the various quiet occasions of environment that need, as occasions such as office, hospital or families.

Description

A kind of retractable door

Technical field

The utility model relates to the retractable door field, can effectively prevent to produce the retractable door of vibrations and noise when specifically being a kind of the use.

Background technology

At present, units such as a lot of offices, enterprise are for safety precaution with to come in and go out vehicle and pedestrian's managerial demand, in the access of unit or the place of being forbidden people without fixed duties etc. at will to enter all be provided with retractable door.The retractable door body of this structure generally by many in regular turn side by side column and some expansion links that are installed between the adjacent upright posts make, axle between its expansion link and the expansion link connects the employing metal bolts and directly flexibly connects, the shortcoming of this connected mode is that its active connection place can produce bigger vibrations and noise because of the hardware direct collision and the friction of joining when using retractable door, thereby influence people's work and life in the surrounding environment, thereby this retractable door generally can only be used for the front door of some units, and for the quiet environment of ask for something, as doorways such as office or corridors, then seldom use, apply thereby influenced it because of the big cause of its noise.

Summary of the invention

The purpose of this utility model is at above-mentioned existing problems and deficiency, provides a kind of and can effectively prevent to produce vibrations and noise, application scenario retractable door widely.

The technical solution of the utility model is achieved in that

A kind of retractable door, comprise many columns that are arranged side by side in regular turn and be installed between the two adjacent upright some the expansion links of cross arrangement in twos, the middle part of two expansion links that wherein intersect flexibly connects by pivot pin, and its characteristics are to be with on the described pivot pin pivot pin cover of being made by nylon or plastics or other nonmetals with shockproof noise reduction effect.

Install for convenience, above-mentioned pivot pin cover is that two two ends that are enclosed within pivot pin respectively can prevent the "T"-shaped or cylindricality that pivot pin and expansion link directly contact or the pivot pin cover of square or other shape.

Direct friction produces vibrations and noise between the expansion link that connects in order effectively to prevent to intersect, further improve shockproof noise reduction of the present utility model, be provided with the pad that at least one can be placed on the shockproof noise reduction of being made by nylon or plastics or other nonmetals on corresponding pivot pin between the interface of above-mentioned two expansion links that intersect.

In order to save cost and convenient the connection, above-mentioned pivot pin adopts bolt and lock nut.

The utility model owing to adopt is with the structure of the pivot pin cover of being made by nylon or plastics or other nonmetals on pivot pin, can prevent effectively between pivot pin and the expansion link that direct friction produces vibrations and noise, thereby the utility model can be used in occasion more widely.Simultaneously owing between the interface of two expansion links that intersect, be provided with the pad of making by nylon or plastics or other nonmetals, direct friction produces vibrations and noise between two expansion links that can further prevent to intersect, thereby make the front door that the utility model not only can the unit of being used in, also applicable to the various quiet occasions of environment that need, as occasions such as office, hospital or families.

Below in conjunction with accompanying drawing the utility model is further described.

Description of drawings

Fig. 1 is the utility model user mode figure;

Fig. 2 analyses and observe enlarged diagram for Fig. 1 shows A-A.

The specific embodiment

As shown in Figures 1 and 2, the utility model is a kind of retractable door, comprise many columns that are arranged side by side in regular turn 1 and be installed between the two adjacent upright 1 some the expansion links 2 of cross arrangement in twos, the middle part of two expansion links 2 that wherein intersect flexibly connects by pivot pin 3, and its characteristics are to be with on the described pivot pin 3 the pivot pin cover of being made by nylon or plastics or other nonmetals 4 with shockproof noise reduction effect.Above-mentioned pivot pin cover 4 is that two two ends that are enclosed within pivot pin 3 respectively can prevent that the "T"-shaped or cylindricality that pivot pin 3 and expansion link 2 directly contact or the pivot pin of square or other shape from overlapping 4.Install for convenience, the utility model adopts two "T"-shaped pivot pin covers 4.For preventing that effectively direct friction produces vibrations and noise between the cross-coupled expansion link 2, further improve shockproof noise reduction of the present utility model, be provided with at least one between the interface of above-mentioned expansion link 2 and expansion link 2 and can be placed on and make the pad 5 of shockproof noise reduction by nylon or plastics or other nonmetals on corresponding pivot pin 3.In order to prevent that pad 5 from producing friction noise because of the wearing and tearing attenuation causes expansion link 2 and expansion link 2 directly to contact, the utility model is provided with two pads 5 between the interface of expansion link 2 and expansion link 2.Above-mentioned pivot pin 3 be provided with various ways, in order to save cost and convenient the connection, the utility model pivot pin 3 adopts bolt and lock nuts to connect.In order to improve the toughness of pivot pin cover 4 and pad 5, strengthen sight, the utility model pivot pin cover 4 and pad 5 adopt the uniform transparent nylon material of color and luster to make.
