Description
Technical Field
[0001] The utility model relates to the technical field of medical lathe brakes, in particular to a central control double brake structure. Background Technique
[0002] Generally referring to a nursing bed nowadays, it is a bed designed according to the treatment needs of patients and their lying habits, with the function that family members can accompany, having multiple nursing functions and operation buttons, and using insulating and safe materials. It is the bed used by patients during treatment, rehabilitation, and recuperation. In order to facilitate the movement of patients, wheels are generally installed at the lower end of the bed body for movement. Therefore, the brakes under the lathe are particularly important.
[0003] Currently, the central control double brake structure in existing medical lathes is relatively complex, with a high manufacturing cost, increasing the economic burden. Content of the Utility Model
[0004] The purpose of the utility model is to provide a central control double brake structure to solve the problems raised in the background technique.
[0005] The embodiment of the present application provides a central control double brake structure, including two groups of wheels. The two groups of wheels are symmetrically arranged. An installation shell is commonly connected between the two wheels. A rotating shaft is rotatably connected inside the installation shell. The rotating shaft passes through the side wall of the installation shell. A rocker is commonly connected between the two rotating shafts. A convex block is fixedly sleeved on the side wall of the rotating shaft, and the convex block is arranged inside the installation shell. Two sliding rods are symmetrically and slidably connected between the wheel and the installation shell. One end of the sliding rod far away from the installation shell is commonly connected with a spring. The other end of the spring is connected to the corresponding side wall of the wheel, and the spring is located inside the wheel. One end of the two sliding rods located inside the installation shell is commonly connected with a resisting block, and the resisting block abuts against the convex block.
[0006] By adopting the above technical solution, during use, when the rocker is shaken, the rotation of the rocker will drive the rotation of the rotating shaft. The rotation of the rotating shaft will drive the rotation of the convex block. The rotation of the convex block will exert a force on the resisting block. The resisting block will move in the vertical direction under the action of the force. The movement of the resisting block will drive the movement of the sliding rod. The movement of the sliding rod will compress the spring. The spring will deform under the action of the force. When the convex block moves to a specified position and the resisting block abuts against the inner wall of the wheel, the wheel will prevent the resisting block from moving, so that the convex block cannot rotate, achieving the braking effect. At the same time, when the force on the rocker disappears, the spring will reset, causing the sliding rod to reset, and thus causing the rocker to reset. Through the above structure, the central control double brake effect can be achieved, and the structure is simple and the operation is convenient, thus achieving the effect of cost saving.
[0007] Optionally, one end of the two rotating shafts on the opposite sides is commonly connected with a pedal.
[0008] By adopting the above technical solution, the user can rotate the rotating shaft through the pedal.
[0009] Optionally, the wheel is installed by means of clamping.
[0010] By adopting the above technical solution, it is convenient to assemble and disassemble the wheel.
[0011] Optionally, a connecting plate is commonly connected between the two wheels.
[0012] By adopting the above technical solution, the firmness of the connection between the two wheels is improved.
[0013] Compared with the prior art, the beneficial effects of the technical solution of the present application are as follows:
[0014] The technical solution of the present application can achieve the effect of central control double braking through the mutual cooperation between structures such as wheels, mounting shells, rotating shafts, rockers, bumps, sliding rods, springs, abutting blocks, pedals and connecting plates. Moreover, the structure is simple and the operation is convenient, thereby achieving the effect of cost saving. Brief Description of the Drawings

When the convex block 5 moves to the designated position and the resisting block 8 abuts against the inner wall of the wheel 1, the wheel 1 will prevent the resisting block 8 from moving, so that the convex block 5 cannot rotate, achieving the braking effect. At the same time, when the force on the rocker 4 disappears, the spring 7 will reset, causing the sliding rod 6 to reset, and thus causing the rocker 4 to reset.
