[0002] Ward rounds are one of the most important and commonly used methods in medical work, and are an important part of ensuring medical quality and training medical personnel. At night, when patients rest, they turn off the lights and the lighting is dim, so medical staff need to bring flashlights when making ward rounds.

[0003] At present, medical staff use flashlights for night rounds. The flashlights carried by medical staff are generally large in size and cannot be worn and can only be held in hand. The flashlight is large and inconvenient to carry. When examining the patient, it has to be held in one hand, which is very inconvenient to work. Sometimes it will be left in the patient's room after the examination.

[0004] Therefore, it is necessary to design a wrist flashlight that is not only convenient to wear but also avoids being left behind in the patient's room. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide a wrist flashlight which is not only convenient to wear but also can avoid being left out in a patient's room.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] A wrist flashlight comprises a wristband, a fixing base and a lighting lamp, wherein two ends of the wristband are connected by Velcro, and the fixing base is fixedly installed on the wristband; the fixing base is provided with a connecting shaft, and the lighting lamp is rotatably sleeved on the connecting shaft; a fixing piece for fastening the lighting lamp is connected between the lighting lamp and the connecting shaft, and the fixing piece is a disc, which is sleeved on the connecting shaft and fixedly connected to the connecting shaft; a plurality of first latch teeth are provided on the disc, and the plurality of first latch teeth are evenly distributed on the outer circumference of the disc at equal intervals; the lighting lamp is provided with a rotating hole, and a plurality of second latch teeth are provided on the wall of the rotating hole; the connecting shaft is inserted into the rotating hole and the lighting lamp can slide on the connecting shaft, and after the lighting lamp rotates, the first latch teeth and the second latch teeth engage with each other.

[0008] As a further improvement of the above technical solution:

[0009] The fixing seat is fixedly connected with a clamping piece, which is sleeved on the connecting shaft and inserted into the rotating hole. The inner wall of the rotating hole is provided with an annular groove, and a slider protrudes from the outer wall of the clamping piece, which is inserted into the annular groove. After the illuminating lamp rotates, the slider can slide along the annular groove. The illuminating lamp can only rotate relative to the fixing seat, so as to avoid the fixing seat and the illuminating lamp being separated and affecting the mutual meshing of the first and second clamping teeth.

[0010] Furthermore, the connecting shaft is formed integrally of a round rod and a square rod, the fixing seat is provided with a mounting groove, the square rod can be slidably inserted into the mounting groove, a rebound device for fastening the connecting shaft is connected between the square rod and the fixing seat, and the disc is located on the round rod. When the square rod is inserted into the mounting groove, the round rod will not rotate with the lighting lamp because the square rod and the round rod are formed integrally, so that the second latching tooth in the rotating hole can mesh with the first latching tooth under the elastic action of the spring.

[0011] Furthermore, the rebound device is installed in the installation groove and includes a movable rod and a first spring. The square rod part is provided with a slide groove, which is located in the installation groove. The slide groove is composed of a first groove, a closing point, a pause point, an opening point and a second groove to form an elastic loop. One end of the movable rod can slide back and forth along the elastic loop, and the other end is connected to the fixed seat. When the movable rod passes through the closing point to the pause point, the first latching tooth disengages from the second latching tooth. When the movable rod passes through the opening point to the second groove, the first latching tooth and the second latching tooth mesh with each other under the elastic action of the first spring. The fixing and angle adjustment of the lighting lamp can be realized by pressing the connecting shaft, which is simple and convenient to operate.

[0012] Furthermore, a bump is protruded from the side of the square rod, a slide groove is arranged on the bump, the movable rod and the first spring are respectively located on both sides of the bump, the first spring is a tension spring and one end of the first spring is connected to the fixed seat, and the other end is connected to the bump. When the sliding end of the movable rod reaches the stop point, the elastic action of the first spring keeps the sliding end of the movable rod at the stop point, the first latching tooth disengages from the second latching tooth, and the lighting lamp can be rotated at will.

[0013] Furthermore, the lighting lamp is provided with a placement groove, the placement groove is connected with the rotating hole and a step is formed at the connection, a button is provided at the suspended end of the round rod, the button is retractably arranged in the placement groove, and the step is blocked between the button and the disc. The provision of the second step can not only prevent the button from extending into the rotating hole, but also prevent the disc on the connecting shaft from escaping from the rotating hole, limiting the movement range of the connecting shaft, so that the disc on the connecting shaft can only move in the rotating hole, ensuring that the first latching tooth and the second latching tooth can both detach and mesh with each other.

[0014] Furthermore, the connecting shaft is provided with a third spring, which is sleeved on the round rod and blocked between the step and the button, so as to facilitate button operation.

[0015] The fixing base is provided with a waterproof switch and an adjustment button for adjusting the lighting brightness. The lighting lamp is installed on the front side of the fixing base, and a USB charging port is provided on the rear side of the lighting lamp. An aluminum battery is provided inside the lighting lamp. The USB charging port is electrically connected to the aluminum battery, and the aluminum battery is electrically connected to the lighting lamp through the waterproof switch.

[0016] Furthermore, the lighting lamp is provided with a dial, and the button is provided with a pointer relative to the dial. The dial is provided according to the first latching tooth on the disc, and one latching tooth corresponds to one scale. When the button is pressed, the movable rod passes through the closing point to the stop point, and the first latching tooth disengages from the second latching tooth, and the lighting lamp can be rotated to adjust the angle. When the lighting lamp is rotated to a suitable position, and the scale on the dial is aligned with the pointer on the button, the button is pressed again, and the movable rod passes through the opening point to the second groove, so that the first latching tooth and the second latching tooth are meshed with each other, so that the lighting lamp is maintained at the adjusted angle, which is convenient for lighting.

[0017] Compared with the prior art, the advantages of the present invention are:

[0018] 1. The present invention comprises a wristband, a fixing base and a lighting lamp. Medical staff can wear the lighting lamp on their wrists through the wristband, which is not only convenient to carry but also does not need to be held in hand when examining patients, thereby improving the work efficiency of medical staff.

[0019] 2. The illuminating lamp is rotatably mounted on the connecting shaft, so that the illuminating lamp can adjust the irradiation position according to the needs of the examination, which is convenient for medical staff to examine the patient, so that the examination position of the patient can be more clearly displayed in front of the medical staff, and it does not affect the rest of other patients. After the first latch and the second latch are engaged with each other, the illuminating lamp cannot continue to rotate, so that the illuminating lamp remains stable after rotation, ensuring that the inspection operation is not hindered.
