[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0027] Please see Figure 1-5In this utility model: a medical protective frame with four-wheel positioning and braking function includes a base plate 1, four vertical tubes 2 are fixedly connected to the top of the base plate 1, a fixed plate 3 and a top plate 4 are provided above the base plate 1, the fixed plate 3 and the top plate 4 are both sleeved on the four vertical tubes 2 and fixedly connected to them, four support rods 5 are inserted through the bottom of the base plate 1 and slidably connected to it, and universal wheels 6 are installed at the bottom end of the four support rods 5. Four electric push rods 7 are inserted through the fixed plate 3 and fixedly connected to it, and the telescopic ends of the four electric push rods 7 are respectively fixedly connected to the four support rods 5. A braking mechanism 8 is provided on each of the four support rods 5.

[0028] In this invention, during use, the base plate 1, four vertical pipes 2, and top plate 4 constitute a complete protective frame. This protective frame, together with the protective cover, can form a protective device. When the protective frame is moved, the four casters 6 at the bottom of the support rod 5 provide support for the protective frame. Moreover, the casters 6 facilitate movement by medical personnel, improving the portability of the protective frame. When using it on uneven surfaces, medical personnel can raise or lower the support rod 5 by activating the electric push rod 7, thereby adjusting the distance between the casters 6 and the base plate 1. By changing the distance between the casters 6 and the base plate 1, the tilting of the protective frame caused by uneven surfaces can be avoided. Furthermore, by adjusting the distance between the casters 6 and the base plate 1, the protective frame can be leveled, thus effectively improving its stability.

[0029] The braking mechanism 8 includes a through groove 801, which is opened on the support rod 5. An electric push rod 802 is inserted through the inner wall of the through groove 801 and fixedly connected thereto. A lifting block 803 is fixedly connected to the telescopic end of the electric push rod 802. A friction cover 804 is fixedly connected to the bottom of the lifting block 803. The friction cover 804 is sleeved on the top of the universal wheel 6.

[0030] After the protective frame is moved to the appropriate position, when it is necessary to lock the caster wheel 6, the medical staff activates the electric push rod 802. The electric push rod 802 will drive the lifting block 803 to descend along the inner wall of the through groove 801. During this process, the friction cover 804 will move downward and come into contact with the rubber wheel of the caster wheel 6. As the friction cover 804 moves downward, the rubber wheel of the caster wheel 6 is squeezed and deformed. Then the rubber wheel of the caster wheel 6 will slide into the inner side of the friction cover 804. At this time, due to the friction, the rubber wheel of the caster wheel 6 cannot rotate, thus achieving the effect of braking the caster wheel 6. Moreover, due to the friction, the caster wheel 6 cannot rotate vertically on the support rod 5. The caster wheel 6 is double-braked. Compared with the existing caster wheel 6 brakes that require two braking methods to stop the caster wheel 6, the practicality is effectively improved.

[0031] Please see Figure 4The bottom of the inner side of the friction cover 804 is rounded, and the inner side of the friction cover 804 is rough.

[0032] In this invention, the arc-shaped friction cover 804 allows the universal wheel 6 to slide more smoothly into the inner side of the friction cover 804, thereby reducing wear. The rough inner side of the friction cover 804 can increase friction and improve the stability of braking the universal wheel 6.

[0033] Please see Figure 1-5 Among them, a lifting ring 9 is threadedly connected to the friction cover 804, and a rubber ring 10 is fixedly connected to the bottom of the lifting ring 9.

[0034] In this invention, when encountering slippery road surfaces, rotating the lifting ring 9 can drive the rubber ring 10 to descend. After the bottom of the rubber ring 10 contacts the ground, the frictional force enhances the braking effect on the protective frame and improves the stability of the protective frame.

[0035] Please see Figure 5 Among them, the outer side of the lifting ring 9 is fixedly connected with a ring-shaped anti-slip strip 11, which is square in shape.

[0036] In this invention, the anti-slip strip 11 facilitates the rotation of the lifting ring 9 by medical staff, thereby improving the practicality of the device.

[0037] Please see Figure 1 , 2 5, wherein: the outer side of the support rod 5 is fixedly connected to the limiting strip 12, and the outer side of the limiting strip 12 is slidably connected to the base plate 1.

[0038] In this invention, the limiting strip 12 can provide a limiting effect between the support rod 5 and the base plate 1, thereby improving the stability of the device.

[0039] The above are merely preferred embodiments of this utility model; however, the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and its improved concept, should be included within the scope of protection of this utility model.
