Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of casters, in particular to a supporting caster for medical equipment. Background Art
[0002] Casters are a general term, including movable casters, fixed casters and movable casters with brakes. Movable casters are what we call universal wheels, and their structure allows 360-degree rotation; fixed casters are also called fixed casters, which have no rotating structure and cannot rotate. Usually, the two types of casters are generally used in combination. For example, the structure of a trolley is two fixed wheels in the front and two universal wheels in the back near the push handle.
[0003] The existing casters can achieve the lifting of the wheels by rotating the screw, making it more convenient to move the equipment when it needs to be moved. Moreover, the rotating screw does not require the help of external tools and can be directly operated by hand, which is simple and easy. The limit nut makes it easier to operate and more efficient when fine-tuning the lifting of the wheels in a small range.
[0004] However, there is a lack of stable components to prevent the position of the equipment from changing during use, which may lead to medical accidents. Therefore, a support caster for medical equipment is proposed to solve the above problem. Utility Model Content

[0027] 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.
[0028] Reference Figure 1 , Figure 2 , Figure 3 The utility model provides an embodiment: a support caster for medical equipment, comprising a moving wheel 1, a caster frame 3 is arranged outside the moving wheel 1, a mounting plate 5 is arranged on the upper part of the caster frame 3, a ball plate 6 is fixedly connected inside the mounting plate 5, a connecting turntable 11 is fixedly connected to the bottom of the ball plate 6, a screw rod 7 is threadedly connected to the inside of the connecting turntable 11, a base 8 is fixedly connected to the bottom of the screw rod 7, a pad 9 is fixedly connected to the bottom of the base 8, an adjusting base plate 12 is threadedly connected to the upper side of the screw rod 7, a fixing assembly is threadedly connected to the inside of the caster frame 3, and the rotation of the connecting turntable 11 is connected to the inside of the caster frame 3;
[0029] The fixing assembly includes a bolt 2, which is threadedly connected to the inside of the caster frame 3, and a nut 10 is threadedly connected to the outside of one side of the bolt 2. The bolt 2 is threadedly connected to the moving wheel 1 through the caster frame 3.
[0030] By rotating the adjusting base plate 12, the screw 7 rotates and moves inside the connecting turntable 11, which drives the base 8 and the foot 9 to move and fit with the ground or rise, so as to prevent the movement of the medical device and the casters can rotate smoothly when the medical device moves, so as to move the medical device smoothly, thereby raising and lowering the base 8, avoiding the movement of the medical device during use, resulting in medical accidents, or obstruction during movement.
[0031] Reference Figure 1 , Figure 2 , Figure 3The bottom of the mounting plate 5 is rotatably connected to the shell 4, the shell 4 is fixedly connected to the upper part of the caster frame 3, the four corners inside the shell 4 are fixedly connected to the guide rods 15, the outside of the guide rods 15 is sleeved with a return spring 14, the upper side of the guide rods 15 is slidably connected to the movable plate 13, the movable plate 13 is arranged at the bottom of the mounting plate 5, one end of the return spring 14 is fixedly connected to the bottom of the movable plate 13, the other end of the return spring 14 is fixedly connected to the bottom of the inner wall of the shell 4, and the movable plate 13 is fixedly connected to the outer upper side of the ball plate 6.
