Technical Field

[0001] The utility model relates to the technical field of pediatric nursing carts, and particularly relates to a pediatric nursing cart with a speed limit locking mechanism. Background Technique

[0002] Pediatrics is a comprehensive medical science that comprehensively studies the physical and mental development, health care, and disease prevention and treatment of children. All issues related to children's health and hygiene belong to the scope of pediatrics. Pediatrics has gathered the rich experience of the Chinese nation in raising children and preventing and treating diseases for thousands of years, and has gradually formed its own theoretical and practical system. When medical staff care for children, they will use a nursing cart;

[0003] Traditional pediatric nursing carts have some disadvantages. For existing pediatric nursing carts, due to the single structure of the wheels, the moving speed cannot be limited. When medical staff push the nursing cart, and because there are slopes on some floors, it will lead to too fast a moving speed, and there will still be dangers in certain scenarios. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a pediatric nursing cart with a speed limit locking mechanism, which can effectively solve the problems in the background technique.

A bottom plate is fixedly connected to the lower end of the frame body near the rear side of the connecting piece. A fixing plate is fixedly connected to the lower end of the bottom plate. A control chamber is fixedly connected to the lower end of the fixing plate. A regulating wheel is movably connected to the inner side of the control chamber. A transmission shaft is fixedly connected to the inner side of the regulating wheel. A brake pad is damping movably connected to the outer side of the regulating wheel near the upper side of the control chamber. A connecting frame is fixedly connected to the upper end of the brake pad. One end of the connecting frame is fixedly connected to a transmission frame. A sliding rail is damping slidably connected to the inner side of the transmission frame.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] Such as Figures 1-4As shown, a pediatric nursing vehicle with a speed limiting locking mechanism comprises a frame body 1, a speed limiting mechanism 5 is arranged at the lower end of the frame body 1, the speed limiting mechanism 5 comprises a connecting member 51 fixedly connected to the lower end of the frame body 1, a rolling wheel 52 is movably connected to the inner side of the connecting member 51, a bottom plate 53 is fixedly connected to the rear side of the lower end of the frame body 1 near the connecting member 51, a fixing plate 54 is fixedly connected to the lower end of the bottom plate 53, a control compartment 55 is fixedly connected to the lower end of the fixing plate 54, a regulating wheel 56 is movably connected to the inner side of the control compartment 55, a transmission shaft 57 is fixedly connected to the inner side of the regulating wheel 56, a brake pad 58 is movably connected to the outer side of the regulating wheel 56 near the upper side of the control compartment 55, a linkage frame 59 is fixedly connected to the upper end of the brake pad 58, a transmission frame 510 is fixedly connected to one end of the linkage frame 59, and a sliding rail 511 is dampingly slidably connected to the inner side of the transmission frame 510.

[0021] In this embodiment, the other end of the transmission frame 510 is fixedly connected to a push plate 512, the transmission shaft 57 passes through the interior of the control compartment 55, the transmission shaft 57 and the control compartment 55 are movably connected, the transmission shaft 57 passes through the interior of the connecting member 51, the transmission shaft 57 and the connecting member 51 are movably connected, the transmission shaft 57 passes through the interior of the rolling wheel 52, the transmission shaft 57 and the rolling wheel 52 are fixedly connected, the brake pad 58 is located above the control compartment 55, and one end of the sliding rail 511 is fixedly connected to one end of the control compartment 55.

[0022] Specifically, if the ground is downhill, the medical staff first pushes the pushing plate 512 with their feet, so that the pushing plate 512 drives the transmission frame 510 to slide along the sliding rail 511, and the transmission frame 510 drives the brake pad 58 to slide through the linkage frame 59, so that the brake pad 58 is moved to the upper end of the regulating wheel 56, and the brake pad 58 is in contact with the regulating wheel 56, so that the brake pad 58 has a damping friction effect on the regulating wheel 56. At the same time, when the rolling wheel 52 rolls on the ground, the rolling wheel 52 drives the transmission shaft 57 to rotate, so that the transmission shaft 57 drives the regulating wheel 56 to rotate in the inner side of the control chamber 55, so that the regulating wheel 56 can slowly rotate with the help of the damping friction force of the brake pad 58, so as to achieve the effect of limiting the speed of the rolling wheel 52. If the medical staff no longer pushes the frame body 1, the rolling wheel 52 stops rotating with the help of the damping friction force of the brake pad 58 on the regulating wheel 56, so as to achieve the effect of locking the rolling wheel 52.

[0023] In this embodiment, a universal wheel 2 is fixedly connected to one side of the lower end of the frame body 1 close to the connecting piece 51 , a placement plate 3 is fixedly connected to the inner side of the frame body 1 , and a push frame 4 is fixedly connected to the upper end of the frame body 1 .

[0024] Specifically, place large medical devices inside the frame body 1 and place vial medications on the upper end of the placement board 3. Then, push the push frame 4 to make the universal wheels 2 and the rolling wheels 52 roll on the ground, so that the frame body 1 moves.

[0025] Working principle:

[0026] During use, medical staff first place large medical devices inside the frame body 1 and place vial medications on the upper end of the placement board 3. Then, push the push frame 4 to make the universal wheels 2 and the rolling wheels 52 roll on the ground, so that the frame body 1 moves. When the ground is downhill, first, medical staff use their feet to push the push board 512, so that the push board 512 drives the transmission frame 510 to slide along the sliding rail 511, and the transmission frame 510 drives the brake pad 58 to slide through the linkage frame 59, so that the brake pad 58 moves to the upper end of the regulation wheel 56 and contacts the regulation wheel 56, so that the brake pad 58 has a damping friction effect on the regulation wheel 56. At the same time, when the rolling wheel 52 rolls on the ground, the rolling wheel 52 drives the transmission shaft 57 to rotate, so that the transmission shaft 57 drives the regulation wheel 56 to rotate inside the control chamber 55. Thus, the regulation wheel 56 uses the damping friction force of the brake pad 58 to make the rolling wheel 52 rotate slowly, so as to achieve the function of speed-limiting the rolling wheel 52. If the medical staff no longer push the frame body 1, the rolling wheel 52 stops rotating by means of the damping friction force of the brake pad 58 on the regulation wheel 56, so as to achieve the function of locking the rolling wheel 52. By pushing the transmission frame 510 to slide along the sliding rail 511 and moving the brake pad 58 to the upper end of the regulation wheel 56, the brake pad 58 has a damping friction effect on the regulation wheel 56, which can achieve the purpose of facilitating the slow rotation of the rolling wheel 52, thus realizing the function of speed-limiting the rolling wheel 52. And when the medical staff no longer push the frame body 1, the rolling wheel 52 stops rotating by means of the damping friction force of the brake pad 58 on the regulation wheel 56, so as to achieve the function of locking the rolling wheel 52.
