[0018] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. Example

[0019] like Figure 1-4As shown, a pull-bolt combined shuttle shutter with adjustment and positioning devices includes a box seat 1 and shuttle shutters 5. A plurality of shuttle shutters 5 are arranged above the box seat 1. A rotating shaft 3 is connected to the inner wall of the bottom of the box seat 1 through a bearing 2. A gear plate 4 is sleeved and fixed on the rotating shaft 3 on the inner side of the box seat 1. A push-pull plate 6 that can slide laterally is also arranged between the back side of the box seat 1 and the gear plate 4. A toothed bar 7 is embedded and fixed on the inner side surface of the push-pull plate 6, and the toothed bar 7 is meshed with the teeth on the gear plate 4. A positioning bolt 11 is also inserted on the back side of the box seat 1 and is directly opposite to the push-pull plate 6. The overall pull-bolt combined shuttle shutter structure with adjustment and positioning devices can be reliably and stably adjusted and positioned, and is extremely convenient to use.

[0020] In this embodiment, the upper end of the rotating shaft 3 extends above the box seat 1, and a bearing 12 is provided at the connection between the rotating shaft 3 and the upper box surface of the box seat 1. The bottom of the shuttle louver 5 is fixed to the upper end of the rotating shaft 3, which is convenient for fixing the rotating shaft 3 and allowing it to rotate with the shuttle louver 5.

[0021] In this embodiment, a slide groove 8 and a plurality of roller grooves 9 are further provided on the side wall on the back side of the box seat 1, and a plurality of groups of rollers 10 are provided on the outer side surface of the push-pull plate 6. Two rollers 10 in the same group are located in the corresponding roller grooves 9 and squeeze the rack 7 against the gear plate 4, so that the rack 7 can always be engaged with the gear plate 4, which helps to drive the gear plate 4 to rotate by using the push-pull plate 6. The provided rollers 10 facilitate pulling the push-pull plate and reduce the push-pull resistance.

[0022] In this embodiment, a handle 13 is fixed on the outer side surface of one end of the push-pull plate 6, and the handle 13 extends from the slide groove 8 to the outer side of the box seat 1, so as to facilitate the push-pull plate 6 to slide.

[0023] In this embodiment, the number of the gear plates 4 is at least two, and the gear plates 4 are evenly distributed in the box seat 1 , and can be connected to a plurality of shuttle shutters 5 .

[0024] The principles and advantages of this utility model: Figure 2As shown, to rotate the shuttle shutter 5, first rotate the positioning bolt 11 outward to disengage its inner end from the push-pull plate 6, then hold the handle 13 with your hand, pull the push-pull plate 6 to slide, and the roller 10 rolls in the roller groove 9, which is convenient for pushing the push-pull plate 6 while also limiting it to ensure that the toothed bar 7 is always engaged with the gear plate 4. When the push-pull plate 6 slides, the toothed bar 7 on its inner side rotates with the gear plate 4, and the gear plate 4 will rotate with the shuttle shutter 5 fixed on the rotating shaft 3, and the rotation angle can be controlled by the sliding distance of the push-pull plate 6. After completing the angle adjustment, rotate the positioning bolt 11 inward to allow its inner end to be firmly squeezed on the push-pull plate 6 to squeeze and fix it, so as to achieve rapid positioning. The shuttle shutter adopting this structural design is equipped with an adjustment and positioning device, which can be reliably and stably adjusted and positioned, and is extremely convenient to use, thereby improving practicality.

[0025] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
