Description

Technical Field

[0001] The utility model relates to the technical field of medical radiation-proof trash cans, in particular to a radiation-proof medical waste trash can with a buffer function. Background Art

[0002] The conventional radiation-proof medical waste trash cans are mostly opened by manual lifting, manual sliding or foot pedaling, and then the radioactive medical waste is placed in the trash can. The commonly used foot pedaling operation causes the lid to fall freely and make a loud impact noise. It is inconvenient to control the closing speed of the lid with the foot when closing it, and it is easy to press or hit the auxiliary tools for placing the waste, thereby preventing the lid from closing, which can easily indirectly cause potential exposure risks to doctors caused by radioactive medical waste. While repeatedly opening and closing the radiation-proof medical waste trash can manually, the radioactive medical waste in the radiation-proof medical waste trash can still causes potential exposure to the human body when the lid is stuck, increasing the exposure time of the radioactive medical waste to the human body. The impact noise generated when the lid falls freely and closes also has a great impact on the daily work of the doctor, and it is urgently needed to be improved. Therefore, we propose a radiation-proof medical waste trash can with a buffer function. Utility Model Content

[0003] The utility model aims to provide a radiation-proof medical waste trash can with a buffer function, which solves the problems raised in the background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a radiation-proof medical waste trash can with a buffering function, comprising a box body, a cover body, a hinge mechanism, a buffer mechanism, a connecting rod mechanism and a lever mechanism. One side of the top of the box body is hingedly connected to the cover body through a hinge mechanism. The connecting rod mechanism comprises a connecting rod A and a connecting rod B that are hingedly connected to each other. The top of the connecting rod B is in contact with the bottom surface of the cover body close to the hinge mechanism. The outside of the connecting rod B is inlaid with a limiting sleeve fixed to the outside of the box body. The buffer mechanism comprises a pedestal fixed to the outside of the box body, the pedestal is connected through the connecting rod B, and a spring A is fixedly arranged on the top surface of the pedestal. The buffer mechanism also comprises a pressure plate fixed to the top of the connecting rod B, and the pressure plate is arranged directly above the spring A. The lever mechanism comprises a frame body and a roller body rotatably arranged inside the frame body, and the connecting rod A is penetrated inside the frame body.

[0005] As a preferred implementation of the technical solution of the present application, a pedal is fixedly provided at one end of the connecting rod A away from the connecting rod B, a cylinder is fixedly provided at the bottom of the connecting rod A, and a spring B is embedded inside the cylinder.

[0006] As a preferred implementation of the technical solution of the present application, a groove is provided at the bottom of the box body, the connecting rod A, the cylinder, and the lever mechanism are all arranged inside the groove body, and the spring B is fixed to the bottom of the groove body.

[0007] As a preferred implementation of the technical solution of the present application, the cylinder is located at a distance of 10 cm from the pedal, and the lever mechanism is located at a distance of 10 cm from the connecting rod B.

[0008] As a preferred implementation of the technical solution of the present application, the hinge mechanism includes a shaft sleeve seat fixed to one end of the cover body and an L-shaped bracket fixed to one side of the top of the box body, and the L-shaped bracket is hingedly connected to the shaft sleeve seat through an axis.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] The technical solution of the present application enables the lid to automatically flip open by stepping on a pedal in conjunction with a lever mechanism and a connecting rod mechanism. When the pedal is released, the pressure plate is elastically buffered by spring A, so that the spring A buffers the lid when the lid is closed, thereby solving the problem that the lid of the existing pedal-type trash can falls too fast when closing the lid, causing auxiliary tools for placing waste to be clamped or generating loud noise.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0018] Embodiment 1, as Figure 1-3 As shown, the utility model provides a technical solution: a radiation-proof medical waste trash can with a buffering function, comprising a box body 1, a cover body 2, a hinge mechanism 3, a buffer mechanism 4, a connecting rod mechanism 5 and a lever mechanism 6. One side of the top of the box body 1 is hingedly connected to the cover body 2 through the hinge mechanism 3. The connecting rod mechanism 5 includes a connecting rod A503 and a connecting rod B502 that are hingedly connected to each other. The top of the connecting rod B502 is in contact with the bottom surface of the cover body 2 close to the hinge mechanism 3. The outside of the connecting rod B502 is inlaid with a limiting sleeve 501 fixed to the outside of the box body 1. The buffer mechanism 4 includes a pedestal 403 fixed to the outside of the box body 1. The pedestal 403 is connected through the connecting rod B502. The pedestal 403 A spring A402 is fixedly set on the top surface, and the buffer mechanism 4 also includes a pressure plate 401 fixed to the top of the connecting rod B502, and the pressure plate 401 is arranged directly above the spring A402. The lever mechanism 6 includes a frame 601 and a roller body 602 rotatably set inside the frame 601, and the connecting rod A503 is passed through the frame 601. A groove body is opened at the bottom of the box body 1, and the connecting rod A503, the cylinder 7, and the lever mechanism 6 are all arranged inside the groove body. The spring B701 is fixed to the bottom of the groove body, and the hinge mechanism 3 includes a sleeve seat 301 fixed to one end of the cover body 2 and an L-shaped bracket 302 fixed to one side of the top of the box body 1, and the L-shaped bracket 302 is hingedly connected to the sleeve seat 301 through an axis.

[0019] In a specific embodiment of the present invention, the circular hole of the shaft sleeve seat 301 of the cover body 2 is aligned with the circular hole of the L-shaped bracket 302, and the shaft body is inserted into the circular hole to realize the rotational cooperation connection between the cover body 2 and the L-shaped bracket 302. The right side of the cover body 2 protrudes 5 cm relative to the box body 1. The limiting sleeve 501 is fixed to the outer wall of the box body 1 by adhesive or hot melt process. The inner diameter of the limiting sleeve 501 is 5 mm larger than the diameter of the connecting rod B502, which is convenient for the connecting rod B502 to perform adaptive swing. The top of the connecting rod B502 contacts the bottom surface of the part of the cover body 2 protruding from the box body 1. The cover body 2 is made of heavy stainless steel. When the pedal 504 is not stepped on, the pedal 504 is in a tilted state, and the pressure plate 401 is in a state of compressing the spring A402. When the pedal 504 is stepped on, the spring B701 is compressed. The connecting rod A503 generates a lever effect through the roller body 602 of the lever mechanism 6, so that the connecting rod A503 drives the connecting rod B502 to rise along the limit sleeve 501, and then the connecting rod B502 pushes the cover body 2 to rise. At this time, the pressure plate 401 is lifted along with the connecting rod B502. At this time, the spring A402 is in a stretched state. When the pedal is released, the spring B701 rebounds and resets, causing the connecting rod A503 to rotate and reset, thereby causing the connecting rod B502 to descend along the limit sleeve 501. When the pressure plate 401 presses the spring A402, the spring A402 can elastically buffer the pressure plate 401 so that the cover body 2 can be slowly closed. A rubber ring can be set around the bottom of the cover body 2 for shock absorption and noise reduction, thereby avoiding the cover body 2 from closing quickly and instantly when the pedal 504 is released, causing a loud noise or clamping the auxiliary tools for placing waste.

[0020] In the preferred technical solution, a pedal 504 is fixedly provided at one end of the connecting rod A503 away from the connecting rod B502, a cylinder 7 is fixedly provided at the bottom of the connecting rod A503, a spring B701 is embedded inside the cylinder 7, and the cylinder 7 cooperates with the spring B701 to achieve elastic lifting and reset of the pedal 504 after it is stepped on.

[0021] In the preferred technical solution, the cylinder 7 is located 10 cm away from the pedal 504, the lever mechanism 6 is located 10 cm away from the connecting rod B502, the frame 601 of the lever mechanism 6 can limit the position of the connecting rod A503, and the roller body 602 facilitates the smooth rotation of the connecting rod A503.

[0022] In the preferred technical solution, a U-shaped handle 201 is fixedly provided on the top surface of the cover body 2, and the U-shaped handle 201 is used to manually lift the cover body 2. A universal wheel group with a brake is fixedly provided on the bottom of the box body 1, and the universal wheel group with a brake is used to move the box body 1. The brake mechanism can lock the universal wheel group.

[0023] Working principle: when the pedal 504 is not stepped on, the pedal 504 is in a tilted state, the pressure plate 401 is in a state of compressing the spring A402, and the cover body 2 is in a closed state; when the pedal 504 is stepped on, the spring B701 is compressed, and the connecting rod A503 generates a lever effect through the roller body 602 of the lever mechanism 6, so that the connecting rod A503 drives the connecting rod B502 to rise along the limiting sleeve 501, and then the connecting rod B502 pushes the cover body 2 to rise, and at this time the pressure plate 401 is lifted along with the connecting rod B502, and at this time the spring A402 is in a stretched state; when the pedal is released, the spring B701 rebounds and resets, so that the connecting rod A503 rotates and resets, thereby causing the connecting rod B502 to descend along the limiting sleeve 501, and when the pressure plate 401 compresses the spring A402, the spring A402 can elastically buffer the pressure plate 401, so that the connecting rod B502 can elastically buffer and support the cover body 2, so that the cover body 2 can be slowly closed.
