DETAILED DESCRIPTION

[0030] In order to make the purpose, technical scheme and advantages of the utility model more clear and intelligible, the following will be further described in detail in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0031] The specific implementation of the utility model will be described in detail in combination with specific examples.

[0032] Please refer to Figures 1 to 6 The utility model embodiment provides a soft curtain quick roll-up door bottom beam, which comprises two fixed frames 1, connecting pieces 2 are installed in the interiors of the two fixed frames 1, connecting beams 3 are installed on the sides of the two connecting pieces 2 close to each other, connecting structures 4 are arranged in the interiors of the connecting beams 3, and positioning structures 5 are arranged in the interiors of the connecting pieces 2.

[0033] In the embodiment of the utility model, please refer to Figures 2 to 4The connecting structure 4 comprises a sliding groove 41, the sliding groove 41 is arranged in the connecting beam 3, the inner wall of the sliding groove 41 is slidably connected with two sliding blocks 46, the upper surface of the sliding block 46 is fixedly connected with a limiting block 44, the inner wall of the upper limiting block 44 is fixedly connected with a sliding rod 49, the inside of the connecting beam 3 is provided with a notch 53, the inner wall of the sliding groove 41 is slidably connected with a connecting plate 43, the inner wall of the connecting plate 43 is provided with a limiting groove 45, the limiting groove 45 is slidably connected with the sliding rod 49, the inside of the limiting groove 45 is provided with two springs 47, and the two ends of the spring 47 are fixedly connected with the sliding rod 49 and the connecting groove 42 respectively.

[0034] In the embodiment of the utility model, please refer to Figure 5 and Figure 6The positioning structure 5 includes two slots 53, which are formed on the connector 2. A positioning rod 56 is slidably connected to the inner wall of the connector 2. A pull plate 52 is slidably connected to the inner wall of the slots 53. The pull plate 52 is fixedly connected to the positioning rod 56. A connecting piece 55 is fixedly connected to the arc surface of the positioning rod 56. A top spring 54 is sleeved on the arc surface of the positioning rod 56. The two ends of the top spring 54 are fixedly connected to the connecting piece 55 and the connector 2, respectively. An auxiliary groove 58 is formed at the end of the positioning rod 56 away from the connector 2. A roller 57 is rotatably connected inside the auxiliary groove 58. Positioning grooves 51 are formed on the sides of the two fixed frames 1 that are far apart from each other. The positioning rod 56 is adapted to the positioning groove 51. When positioning the connecting beam 3 is required, the connecting beam is pulled to move it. The connecting beam moves the connecting piece 2, which in turn moves the positioning rod 56. The positioning rod 56 moves the auxiliary groove 58, which in turn rotates the roller 57. Under the compression of the fixed frame 1, the top spring 54 retracts. After moving to the appropriate position, the top spring 54 stretches, moving the connecting piece 55. The connecting piece 55 then moves the positioning rod 56 into the auxiliary groove 58 for positioning. When it is necessary to separate the positioning structure 5 from the fixed frame 1, the pull plate 52 is pulled to retract the positioning rod 56, and then the positioning rod 56 separates from the positioning groove 51. The roller 57 has a circular cross-section and is made of rubber. The rubber material increases the friction between the roller 57 and the fixed frame 1, preventing the roller 57 from slipping during movement and causing severe wear. The pull plate 52 has a U-shaped cross-section and is made of stainless steel. The stainless steel material can increase the service life of the pull plate 52 and prevent it from rusting during use.

[0035] The working principle of the bottom beam of the soft curtain quick-rolling door provided by this utility model is as follows: When it is necessary to connect the connecting plate 43 and the connecting beam 3, the connecting plate 43 is pulled to move.

After moving to the appropriate position... When the limiting block 44 is released, the spring 47 retracts, causing the slider 46 to move away from each other. The slider 46 is connected and fixed to the slide groove 41. The limiting rod 48 can limit the slide rod 49 to prevent deformation during use, thus improving the sliding stability of the slide rod 49. The limiting rod 48 can also limit the spring 47 to prevent over-deformation during use, thus increasing the service life of the spring 47. The stainless steel material can also increase the service life of the slide rod 49 and prevent excessive corrosion during use.

[0036] When the positioning of the connecting beam 3 is needed, the connecting beam is pulled to move, the connecting beam drives the adapter 2 to move, the adapter 2 drives the positioning rod 56 to move, the positioning rod 56 drives the auxiliary groove 58 to move, the auxiliary groove 58 drives the roller 57 to rotate, wherein the top spring 54 is contracted under the extrusion of the fixed frame 1, the top spring 54 is stretched to drive the connecting piece 55 to move after being moved to the appropriate position, the connecting piece 55 drives the positioning rod 56 to be positioned by being inserted into the auxiliary groove 58, when the positioning structure 5 needs to be separated from the fixed frame 1, the pull plate 52 is pulled to drive the positioning rod 56 to be withdrawn, then the positioning rod 56 is separated from the positioning groove 51, the rubber material can increase the friction between the roller 57 and the fixed frame 1, so that the roller 57 is prevented from being seriously abraded due to sliding when moving, the stainless steel material can increase the service life of the pull plate 52, and rust of the pull plate 52 is avoided when the pull plate 52 is used again.

[0037] The circuit and the control involved in the utility model are prior art, and too much repetition is not performed herein.

[0038] The above is only an embodiment of the utility model, and does not limit the patent range of the utility model, and equivalent structures or equivalent process transformations using the utility model specification and the attached drawings, or direct or indirect application in other related technical fields are also included in the patent protection range of the utility model.
