Description

Vertical operation shadowless lamp Technical Field The utility model belongs to the technical field of shadowless lamps, and particularly relates to a vertical operation shadowless lamp. Background The shadowless lamp is used for illumination in the surgical operation process, the formed shadowless illumination area can promote operators to carefully observe the incision, the affected part and other parts, small objects with low contrast and different depths in the optimal observation part Ding Qiekou and the body cavity can be accurately distinguished, the tissue outline, the color and the movement of surgical equipment can be accurately distinguished, and the head, the hand and the instruments of the operators can possibly cause interference shadow to the surgical parts, so the shadowless lamp is designed to eliminate the shadow as much as possible, the color distortion can be reduced to the minimum degree, the operation precision is improved, and the operation is accelerated. The existing operation shadowless lamp is divided into a vertical type shadowless lamp and a hanging type shadowless lamp, the vertical type shadowless lamp can be moved, the operation shadowless lamp is flexible to use, but because the supporting rod of the shadowless lamp is longer, the occupied space is larger, the space occupation is affected when the operation shadowless lamp is not needed to be used or stored and placed, and the shadowless lamp with a foldable or telescopic part is more troublesome when being used and unfolded, and the use efficiency is affected. For this reason, we propose a vertical operation shadowless lamp to solve the above problems. Disclosure of utility model The utility model aims to solve the problems that in the prior art, the use is troublesome when the lamp is unfolded after being stored, and the use efficiency is affected. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The vertical operation shadowless lamp comprises a base, wherein an upright post is fixedly connected to the top surface of the base, a first connecting rod is hinged to the top end of the upright post, a second connecting rod is arranged at the other end of the first connecting rod in a connecting mode, and a lamp is rotatably arranged at the top end of the second connecting rod; The first connecting rod is provided with a first unidirectional ratchet wheel component at the joint of the first connecting rod and the upright post, a second unidirectional ratchet wheel component is provided at the joint of the second connecting rod and the upright post, the top surface of the base is fixedly connected with a first placing seat matched with the first connecting rod, and the top end of the upright post is fixedly connected with a second placing seat matched with the lamp and the second connecting rod. Preferably, the first unidirectional ratchet wheel assembly comprises a first ratchet wheel fixedly installed on the upright post, the hinge position of the first connecting rod and the upright post is coaxially arranged with the first ratchet wheel, and the side wall of the first connecting rod is rotationally connected with a first pawl matched with the first ratchet wheel. Preferably, the side wall of the first connecting rod is fixedly connected with a first spring for driving the first pawl to be close to the first ratchet wheel. Preferably, the outer side wall of the first connecting rod is rotatably connected with a first knob, and the first knob is coaxially connected with the first pawl. Preferably, a first magnetic attraction component which is attracted mutually is fixedly arranged between the first placing seat and the first connecting rod, and a second magnetic attraction component which is attracted mutually is fixedly arranged between the second placing seat and the second connecting rod. Preferably, the side wall of the upright post is fixedly connected with a limiting rod, and the side wall of the first connecting rod is provided with a limiting groove for the limiting rod to pass through and move. Preferably, the limiting groove is arc-shaped and smaller than 180 degrees. In summary, the vertical surgical shadowless lamp has the technical effects and advantages that the stable storage and placement of the first connecting rod, the second connecting rod and the lamp are realized through the first placing seat and the second placing seat, the lifting adjustment and the loosening locking of the first connecting rod are realized through the first unidirectional ratchet wheel assembly, and the lifting adjustment and the loosening locking of the second connecting rod are realized through the second unidirectional ratchet wheel assembly.
