Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The utility model provides a freight train dust curtain, includes two folding tracks 1 that set up relatively, is equipped with pivoted primary shaft 2 between two tracks 1, and primary shaft 2 both ends rotate with two tracks 1 respectively and are linked. A second shaft 3 is further connected between the two tracks 1 in a sliding mode, the first shaft 2 is connected with the second shaft 3 through a curtain body 4, and when the first shaft 2 rotates, the curtain body 4 can be wound on the first shaft 2 and can drive the second shaft 3 to slide along the two tracks 1.

As shown in fig. 7, in a specific use, two folding rails 1 of the device are installed on a vehicle frame, and the two folding rails 1 are respectively positioned at two sides of a wheel. The folding track can be fixed on the frame by welding, bolt connection and other modes and can be adjusted according to actual conditions. When in use, the foldable track 1 is unfolded, and after the foldable track is unfolded, the first shaft 2 is rotated to loosen the curtain body 4 wound on the first shaft and move the second shaft 3 downwards along the two tracks 3. The shielding of the wheels can be realized after the curtain body 4 is loosened. When the curtain is not used, the first shaft 2 is rotated reversely, the curtain body 4 is wound on the first shaft 2, the second shaft 3 moves upwards along the two tracks 1, and after the winding is finished, the tracks 1 are folded.

The above-described structure of the parts is similar to the prior art window shades, and therefore, the specific structure thereof is well known to those skilled in the art, and can be further adjusted according to the actual situation. In the above structure: track 1 can fold or expand according to actual conditions when facilitating the use, and occupation in reducible space after folding to it can reduce it and collide with impaired. Specifically, the method comprises the following steps: the folding rail 1 is a kind of shell structure with a distance in between which is slightly larger than the diameter of the first shaft 2 and the second shaft 3. The first shaft 2 can rotate through the motor 6, an output shaft of the motor 6 penetrates through the track 1 to be connected with the first shaft 2, or one end of the first shaft 2 extends out of the track 1, and an output shaft of the motor 6 is connected with the extending end thereof. The motor 6 can be a stepping motor, and the shell of the motor is fixedly connected with the frame.

The track 1 can be folded in various configurations, preferably:

as shown in fig. 1 to 4, the foldable vehicle frame is divided into an upper rail 11 and a lower rail 12, the upper rail 11 is fixedly connected with the vehicle frame, one end of the upper rail 11 is hinged with one end of the lower rail 12, and the folding of the rails can be realized by adopting a hinged mode. The specific hinged position can be adjusted according to the actual situation, and if the hinged end is arranged at the inner side, the hinged end is folded inwards; and vice versa. A fixing device 5 is arranged between the upper rail 11 and the lower rail 12, and the movement between the upper rail 11 and the lower rail 12 can be limited by the fixing device 5, namely, the rotation of the upper rail 11 and the lower rail 12 is limited by the fixing device 5 when the upper rail is unfolded or folded.

When the device is unfolded, the upper track 11 and the lower track 12 are positioned on the same straight line to form a complete track; after being folded, an included angle (which may be 90 degrees) exists between the upper rail 11 and the lower rail 12. In addition, the upper rail 11 and the lower rail 12 are only relatively, and are installed as usual in the upper portion as the upper rail and in the lower portion as the lower rail.

The fixing means 5 mainly serves to limit the rotation of the lower rail 12 with respect to the upper rail 11, and therefore, it can be implemented in various structures, such as: the bolt can be adopted for realizing, the bolt is arranged on the upper track 11, and the pin hole matched with the bolt is arranged on the lower track 12. Of course, the following structure is preferably employed:

the fixing device 5 includes a fixing plate 51 and an elastic protrusion 52, the fixing plate 51 is provided with a through hole 511 or a blind hole 512 (as shown in fig. 6) matching with the elastic protrusion 52, and the elastic protrusion 52 can extend into the through hole 511 or the blind hole 512. One end of the fixed plate 51 is hinged with the upper rail 11, and the elastic bulge 52 is arranged on the lower rail 12; or one end of the fixed plate 51 is hinged with the lower rail 12, and the elastic protrusion 52 is provided on the upper rail 11.

When folded or unfolded, the fixing plate 51 is rotated such that the through hole 511 or the blind hole 512 of the fixing plate 51 is engaged with the elastic protrusion 52. When engaged, the resilient protrusions 52 are first pressed down and then spring up to extend into the through holes 511 or the blind holes 512. The method comprises the following specific steps: when the blind hole 512 is formed, the elastic bulge 52 is extruded to extend into the blind hole, and the elastic bulge 52 is tightly combined with the blind hole due to the action of elastic potential energy to play a role in connection; in the case of the through hole 511, by pressing the elastic projection 52 into the through hole 511, since the height of the projection 52 is greater than the depth of the through hole 511, the coupling effect can be more effectively performed.

The number of the through holes 511 or the blind holes 512 and the elastic protrusions 52 on the fixing plate 51 can be set according to practical situations. Different through holes 511 or blind holes 512 are combined with the elastic protrusions 52 at different positions in an arrangement manner, so that the lower rail 12 can be retracted in different degrees, and preferably two or more elastic protrusions 52 can be arranged as required. The method comprises the following specific steps: when an elastic protrusion 52 is provided, two through holes 511 or blind holes 512 are provided on the fixing plate 51; when two elastic protrusions 52 are provided, the fixing plate 51 is provided with a through hole 511 or a blind hole 512.

The elastic protrusion 52 includes a protrusion 521 and a spring 522. When the elastic protrusion 52 is provided on the lower rail 12, the coupling groove is located on the lower rail 12, and vice versa on the upper rail 11. Both ends of the spring 522 are coupled with the coupling groove and the protrusion 521, respectively, and the protrusion 521 can be pressed into the coupling groove. The shape of the projection 521 is preferably cylindrical.

As shown in fig. 8, the dust-proof curtain is installed outside the wheel, and the curtain body 4 may be made of air-permeable dust-proof cloth to prevent the curtain body from being drawn into the wheel by a pressure difference generated when the wheel rotates at a high speed. Meanwhile, in order to avoid the second shaft 3 from falling off due to vibration, the second shaft 3 can be connected with the two rails 1 (the lower rail 12) through the pin shaft after moving downwards, the second shaft 3 and the two rails 1 are provided with corresponding pin holes, and the pin shaft can penetrate through the pin holes to realize connection.

Although only the preferred embodiments of the present invention have been described in detail, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art, and all changes are encompassed in the scope of the present invention.
