DETAILED DESCRIPTION
[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0021] like Figure 1 , Figure 2, Figure 3 , Figure 4 The hanging curtain type sponge door seal shown in the utility model includes two side door seals 1 and an upper door seal 2 in order to make the sponge door curtain stick to the car body without using a motor to drive the sponge door curtain to move. The side door seal 1 includes a side door column 11 and a side sponge door curtain 12. The side door seal 1 is provided with a propping mechanism 6 for pushing the sponge door curtain to press on the car body. The propping mechanism 6 includes a first support plate 61. One end of the first support plate 61 is connected to the side door column 11, and the other end is rotatably connected to a rotating shaft 62. The rotating shaft 62 is also rotatably connected to a second support plate 65. A sleeve 63 and a torsion spring 64 are provided between the first support plate 61 and the second support plate 65. The sleeve 63 is sleeved outside the rotating shaft 62. The sleeve 63 separates The first support plate 61 and the second support plate 65 are opened, and the torsion spring 64 is sleeved outside the sleeve 63, and the two ends of the torsion spring 64 are respectively connected to the first support plate 61 and the second support plate 65. When the angle between the first support plate 61 and the second support plate 65 is 0, the torsion spring 64 does not generate elastic force, but when the angle between the first support plate 61 and the second support plate 65 changes, the torsion spring 64 generates elastic force, and the end of the second support plate 65 away from the first support plate 61 is connected to the first connector 66, and the first connector 66 is connected to the second connector 67 by a rope connection. The second connector 67 is connected to the end of the side sponge door curtain 12 away from the side door post 11, thereby under the action of the torsion spring 64, the sponge door curtain is opened.
[0022] Specifically, since the height of the carriages of the same model is basically the same, when the truck is reversing, the carriage may be offset, so that the carriage is closer to one side of the sponge door curtain 12. In order to make the two sponge door curtains close to the carriage, the width between the two side sponge door curtains 12 should be smaller than the width of the carriage. When reversing, the carriage pushes the two side sponge door curtains 12 to move backward, so that the second support plate 65 rotates, and the angle between the first support plate 61 and the second support plate 65 also changes accordingly, but under the influence of the elastic force applied by the torsion spring 64, the sponge door curtain is close to the carriage.
[0023] Furthermore, the upper door seal 2 includes an upper sponge door curtain 22 , and the side door pillar 11 is provided with a slot 13 corresponding to the upper sponge door curtain 22 , and the side of the upper sponge door curtain 22 is inserted into the slot 13 , which limits the upper sponge door curtain 22 from moving forward and backward.
[0024] Furthermore, a plurality of magnet strips 3 are provided at the lower end of the upper sponge door curtain 22, and the magnet strips 3 can be adsorbed on the top of the carriage.
[0025] Furthermore, the upper door seal 2 includes an upper door column 21, which is provided with a movable groove for the upper sponge door curtain 22 to pass through, and a retracting roller 4 for retracting and releasing the upper sponge door curtain 22 is connected above the upper door column 21. The upper sponge door curtain 22 can be retracted or released by rotating the retracting roller 4.
[0026] Furthermore, both ends of the retractable roller 4 are respectively connected to wire wheels 5 , and a pull rope (not shown in the figure) is wound around the wire wheels 5 to facilitate the rotation of the retractable roller 4 .
[0027] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
