DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example

[0026] See Figures 1 to 3 As shown, a roll-type stretched soft substrate comprises a mounting bracket 1, a soft substrate body 2 arranged on the mounting bracket, and the mounting bracket is provided with a plurality of parallel vertical adjustment slots 3 and a circular shaft hole 4; in this embodiment, the mounting bracket is a plastic structure, and can also be a ceramic or other structure, which is mainly used for supporting operation;

[0027] In actual application, the side of the mounting bracket is provided with a strip groove 5 for passing the soft substrate; the mounting bracket is provided with a winding shaft 6 and a plurality of lifting rods 7; in this embodiment, the winding shaft and the lifting rods are both insulating plastic structures. The number of the lifting rods is three or four.

[0028] During installation, the end of the winding shaft is arranged in the circular shaft hole through the bearing 8; the end of the lifting support rod is arranged in the vertical adjustment slot, and the locking screw 9 is threadedly connected to the end of the lifting support rod; the winding shaft can wind up the soft substrate body. Since the longer the winding length, the larger the winding diameter, in order to reduce the space occupied by the installation bracket, it needs to be used in conjunction with the lifting support rod. It mainly changes the length of the folded soft substrate body by adjusting the position between adjacent lifting support rods, and can be locked and positioned by the locking screw after adjustment, thereby ensuring the stability and reliability of the length adjustment.

[0029] In actual application, the lifting support rod is lifted and lowered in the vertical adjustment slot and is locked in place by a locking screw; one end of the soft substrate body is wrapped around the winding shaft, and the middle part of the soft substrate body is arranged in a wave shape on the lifting support rod in sequence, and the other end of the soft substrate body passes through the strip groove and extends out of the mounting bracket.

[0030] In order to facilitate the winding operation, a rotating handle 10 is fixed to the end of the winding shaft, and a locking screw 11 is provided on the rotating handle; when in use, the rotating handle extends out of the side of the mounting bracket, and the rotating handle drives the winding shaft to rotate and is positioned by the locking screw.

[0031] In actual application, in order to prevent the soft substrate body from automatically extending and retracting, a stop groove 15 is provided on the top wall of the strip groove, a stop plate 12 is provided in the stop groove, and a spring 13 is provided between the stop plate and the top wall of the stop groove; the stop plate cooperates with the bottom wall of the stop groove to limit the position of the soft substrate body. Only when the external force is greater than the friction between the stop plate and the soft substrate body can the soft substrate body be stretched outward, or when the winding force of the winding shaft is greater than the friction between the stop plate and the soft substrate body, the soft substrate body can be retracted inward.

[0032] The bottom plate of the mounting bracket is fixed with mounting holes 14, which can facilitate the installation and positioning of the mounting bracket.

[0033] The utility model has positive effects: the structure of the utility model is reasonably arranged, and a winding shaft rod is arranged to cooperate with a lifting support rod. When in use, the winding shaft rod winds up the soft substrate body. When the length of the wound soft substrate body is large, the overall diameter will also increase. Therefore, in order to reduce the winding diameter, the soft substrate is arranged in a wave shape through the lifting support rod, and the length of the stored soft substrate body can be increased within a small space. When in use, the length adjustment can be achieved by discharging the material through the winding shaft rod, and the lifting support rod can be gradually moved toward the middle to reduce the length of the wavy soft substrate body, so that the external length can be adjusted. The overall structure occupies a small space, is convenient for length adjustment, and has strong applicability and good practicality.
