Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
[0019] Example
[0020] A head-mounted inspection lamp described in this embodiment, such as Figure 1 As shown, it includes a headband 1 for wearing on the head of medical personnel. When the headband 1 is in use, it is in a ring structure, so that it is convenient for medical personnel to wear it;
[0021] like Figure 1 and Figure 4As shown, a buffer layer 2 for separating the headband 1 from the skin of the medical staff is provided on the other side of the headband 1, and the buffer layer 2 is made of moisture-absorbing and perspiration-releasing fabric, such as linen fabric, bamboo fiber fabric, nylon and nylon fabric, etc.; therefore, when the headband 1 is worn on the head of the medical staff, the buffer layer 2 is the side in contact with the skin of the medical staff, so that the design of the buffer layer 2 can provide the medical staff with better comfort; and the headband 1 is made of moisture-absorbing and perspiration-releasing fabric. When the medical staff may sweat during surgery or examination, sweating may cause the headband 1 to slide. Therefore, the design of the buffer layer 2 can also make the headband 1 more stably worn on the head of the medical staff;
[0022] like Figure 1 As shown, a lighting assembly for examining a patient is arranged on one side of the body of the headband 1, and the lighting assembly includes a lamp body 6, a slide plate 8 is horizontally arranged on one side of the body of the headband 1, and a sliding sleeve 7 is mounted on the slide plate 8 and slidably cooperates with the slide plate 8, and the lamp body 6 is located on the sliding sleeve 7, and the slide plate 8 is fixed to the headband 1 through a fixing block; the lamp body 6 is an existing known technology, and after the lamp body 6 is installed, it is electrically connected to a battery and a control switch, respectively, the battery is used to power the lamp body 6, and the control switch is used to control the start and stop of the lamp body 6; the lamp body 6 is preferably a miniature shadowless lamp, which is generally composed of a single or multiple lamp heads, which can eliminate shadows as much as possible and minimize color distortion; when the slide plate 8 is specifically installed through the fixing block, as shown Figure 1 In the position shown in , the left and right walls of the slide plate 8 are fixed with fixing blocks, and one side wall of the fixing block is fixed on the headband 1; at the same time, a gap for the sliding sleeve 7 to slide is reserved between the slide plate 8 and the headband 1; therefore, when in use, when the sliding sleeve 7 slides left and right, it can drive the lamp body 6 to slide left and right, so that the position of the lamp body 6 can be adjusted, which is convenient for medical personnel to operate;
[0023] Further preferably, Figure 1 and Figure 4 As shown, a threaded through hole communicating with the inside and outside is opened on the sliding sleeve 7, and a screw 4 is connected to the threaded through hole. When in use, after the sliding sleeve 7 drives the lamp body 6 to slide to a suitable position, the position of the sliding sleeve 7 is limited by tightening the screw 4, thereby limiting the position of the lamp body 6, so that the lamp body 6 can be used more stably;
[0024] like Figure 1 and Figure 4As shown, the lamp body 6 is fixed on the sliding sleeve 7 through the universal ball 5. The universal ball 5 is a known technology. The universal ball 5 is also called a universal conveying ball, a universal ball, a steel ball wheel, a bull's eye bearing, etc. It has a flexible rolling performance, which can make the working plate, material box and other objects moving on it slide very flexibly; therefore, when the lamp body 6 and the sliding sleeve 7 are connected through the universal ball 5, the universal ball 5 can drive the lamp body 6 to rotate to different directions, so that the angle of the lamp body 6 can be adjusted, which is convenient for doctors to use;
[0025] like Figure 1 As shown, the slide plate 8 is in an arc-shaped structure, because the headband 1 is in an annular structure when worn on the doctor's head. When the slide plate 8 is in an arc-shaped structure, the lamp body 6 also rotates in an annular direction, which is convenient for the doctor to operate;
[0026] like Figure 1 , Figure 2 and Figure 3 As shown, one end of the headband 1 is a fixed end, and the other end is a movable end; a limit frame 9 is provided on the fixed end, and the limit frame 9 is in a state of being connected to the left and right; a card block 10 is fixed in the limit frame 9, and the card block 10 is made of elastic material; a gap is left between the card block 10 and the limit frame 9 for the movable end of the headband 1 to penetrate; a plurality of latch teeth 3 are provided at the movable end of the headband 1, and all the latch teeth 3 are arranged at intervals along the length direction of the headband 1; in the natural state of the card block 10, the latch teeth 3 are engaged with the card block 10; as shown Figure 2 In the orientation of the middle, the card block 10 is preferably installed in the inner top of the limit frame 9, so that there is a gap between the card block 10 and the inner bottom of the limit frame 9 for the movable end of the headband 1 to penetrate; the card teeth 3 are preferably arranged at equal intervals; when the card connection is implemented, the cross section of the card tooth 3 can be set to a right-angled triangle structure, and one right-angled side of the card tooth 3 is fixed on the headband 1. When the card tooth 3 is engaged, the inclined surface of the card tooth 3 first contacts the card block 10, and then the card tooth 3 is moved, so that the card block 10 can be squeezed during the movement of the card tooth 3. After the card block 10 is squeezed and deformed, the card tooth 3 moves from one side of the card block 10 to the other side of the card block 10, and then the card block 10 can limit the card tooth 3 on its other side without the action of external force; When in use, first insert the movable end of the headband 1 into the gap, then pull the movable end of the headband 1 to drive the latch tooth 3 to move, and squeeze the latch block 10 during the movement of the latch tooth 3, so that the latch tooth 3 can pass through the latch block 10, and when the latch tooth 3 is not pulled to move, the latch block 10 can limit the latch tooth 3, thereby limiting the movable end of the headband 1 in the limit frame 9; when in use, medical staff can pull the movable end of the headband 1 according to the size of their head to adjust the length of the headband 1, so as to facilitate the use of different medical staff, and when pulling, it can be fixed at the position where it is pulled, and there is no need to fix the movable end of the headband 1 again later, so that it is more convenient and quick during use;
[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the front side wall of the limit frame 9 is hinged on one side wall of the limit frame 9 and can swing up and down, and the other side opposite to the hinged side of the limit frame 9 is provided with a lock buckle for locking the front side wall of the limit frame 9; when the front side wall of the limit frame 9 is specifically hinged, it can be hinged on the limit frame 9 by a hinge, or it can be hinged on the limit frame 9 by a pivot; therefore, the front side wall of the limit frame 9 can be opened, and when the front side wall of the limit frame 9 is opened, the latch tooth 3 can be easily taken out from the limit frame 9; because the cross section of the latch tooth 3 is a right-angled triangle structure, when pulling back the latch tooth 3 to take the movable end of the headband 1 out of the limit frame 9, it requires a certain amount of force, which is inconvenient to pull out, and the design of opening the front side wall of the limit frame 9 can make it more convenient and convenient to take the movable end of the headband 1 out of the limit frame 9, which is convenient for next use; when the lock buckle is specifically installed, as shown in the figure Figure 3 The lock buckle includes a movable part and a fixed part, the movable part is fixed on the front side wall of the limit frame 9, and the fixed part is fixed on the bottom of the limit frame 9. Through the cooperation between the movable part and the fixed part, the front side wall of the limit frame 9 is conveniently fixed to avoid the problem that the front side wall of the limit frame 9 is opened and the movable end of the headband 1 is moved out of the limit frame 9;
[0028] In the specific use process: first, the movable end of the headband 1 is passed through the limit frame 9, and then the headband 1 is worn on the head of the medical staff. Then the medical staff pulls the movable end of the headband 1 according to the size of his or her head. During the pulling process, the latch tooth 3 moves. Because the contact surface of the latch tooth 3 and the clamping block 10 is an inclined surface, the movable end of the headband 1 can be easily pulled to move; when it is pulled to a suitable position, stop pulling the movable end of the headband 1. Under the action of the latch tooth 3 and the clamping block 10, the movable end of the headband 1 can be directly limited to achieve the effect of being fixed at that position when pulled to that position; so that the headband 1 can be stably worn on the head of the medical staff, and then the lighting assembly is turned on to examine the patient; in this use process, when adjusting the headband 1, it is only necessary to pull the movable end of the headband 1 to achieve the adjustment as much as possible, and there is no need to constantly twist the fastening screws to adjust the headband 1 as in the prior art, which causes time-consuming and labor-intensive problems; therefore, the present design saves more time and effort during use.
