Abstract
The invention relates to a bottom beam structure of a trackless translational door. The bottom beam structure of a trackless translational door comprises a bottom beam body, wherein the bottom beam body extends transversely and the inside of the bottom beam body is hollow, the bottom beam body is formed by continuously bending a steel plate, a part of surface on the bottom beam body sinks inwards and forms a groove part extending transversely, and the groove is located between two neighboring bending parts; the side face of the bottom beam body is provided with a bending plate, and the bending plate is connected with a transmission rack through a screw mounted in a screw hole. The bottom beam structure of a trackless translational door is simple in structure, and is provided with a rack on the basis of the existing bottom beam so as to facilitate transmission of the translational door, thus the bottom beam structure is convenient and efficient.
Description
Technical field
The present invention relates to the translation door part field, relate in particular to a kind of trackless translation door structure of bottom girder.
Background technology
The translation door door leaf consists of doorframe (claiming again bound edge) and door-plate.Divide three kinds according to the translation door doorframe, the one, aluminium alloy extrusions translation door doorframe (being called for short the aluminium horizontal sliding door), the 2nd, stainless steel translation door doorframe (being called for short the stainless steel translation door), the 3rd, galvanized steel plain sheet translation door doorframe (be called for short zinc-plated translation door, claim again simple door).
A kind of translation door bottom girder of being announced by Chinese patent CN202560077U, it comprises and extending transversely and the bottom girder body of inner hollow, described bottom girder body is formed by the steel plate continuous bending, on described bottom girder body, have part surface to cave inward and form the concave part extended transversely, described concave part is between adjacent two inside bendings.This translation door structure of bottom girder is not suitable for the development of translation door technology, is necessary to make further improvements on this basis, increases rack structure thereon, is convenient to the translation door transmission.
Summary of the invention
The objective of the invention is, in order to overcome the deficiencies in the prior art, provides a kind of trackless translation door structure of bottom girder.
The present invention is achieved through the following technical solutions:
A kind of trackless translation door structure of bottom girder, it comprises and extending transversely and the bottom girder body of inner hollow, described bottom girder body is formed by the steel plate continuous bending, on described bottom girder body, have part surface to cave inward and form the concave part extended transversely, described concave part is between adjacent two inside bendings; The side of described bottom girder body is provided with bending plate, and described bending plate is connected with driving rack by the screw be arranged in screw hole.
Further, the tooth section of described driving rack is trapezoidal shape.
Further, described driving rack is provided with chromium coating.
Further, the thickness of described chromium coating is 2mm.
Further, described bending plate is arranged on the side of bottom girder body by screw.
Further, described bottom girder body comprises upper bottom surface, bottom surface, pair of sidewalls face and connects described side wall surface and the inclined-plane of upper bottom surface or bottom surface, and described concave part distributes on described inclined-plane.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is simple in structure, on the basis of existing bottom girder, tooth bar is installed, and is convenient to the transmission of translation door, convenient and swift.
The accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is left view of the present invention.
The specific embodiment
In order to make purpose of the present invention, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not intended to limit the present invention.
Refer to Fig. 1 and Fig. 2, Fig. 1 is front view of the present invention, and Fig. 2 is left view of the present invention.
Described a kind of trackless translation door structure of bottom girder, it comprises and extending transversely and the bottom girder body 1 of inner hollow, described bottom girder body 1 is formed by the steel plate continuous bending, on described bottom girder body 1, have part surface to cave inward and form the concave part extended transversely, described concave part is between adjacent two inside bendings; The side of described bottom girder body 1 is provided with bending plate 2, and bending plate 2 is arranged on the side of bottom girder body 1 by screw; Described bending plate 2 is connected with driving rack 3 by the screw that is arranged on 4 li of screw holes.
The tooth section of described driving rack 3 is trapezoidal shape, is convenient to processing.
Described driving rack 3 is provided with chromium coating, and the thickness of described chromium coating is 2mm.Prevent in transmission process, the tooth bar serious wear, reduce frequency of maintenance, cost-saving.
Described bottom girder body 1 comprises upper bottom surface, bottom surface, pair of sidewalls face and connects described side wall surface and the inclined-plane of upper bottom surface or bottom surface, and described concave part distributes on described inclined-plane.Wherein, on described the first inclined-plane 4 and the second inclined-plane, the difference outward once, forms the concave part extended transversely, and due to described concave part, between adjacent two inside bendings, therefore can offset a part of stress, reduces the steel plate springback capacity.The both sides of bottom girder body 1 are symmetrically arranged with respectively a described concave part, and these concave parts can strengthen the intensity of bottom girder body 1, overcome by Exposure to Sunlight and cause the uneven and bottom girder problem on deformation that causes of temperature.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any modifications of doing within the spirit and principles in the present invention, be equal to and replace and improvement etc., within all should being included in protection scope of the present invention.
