Description

Technical Field

[0001] This utility model belongs to the field of medical lighting technology, and more specifically, it relates to a medical headlamp with a quick-release buckle. Background Technology

[0002] In precision medical settings such as surgical procedures, dental operations, and emergency care, stable, reliable, and flexibly adjustable lighting is crucial for ensuring a clear surgical field and precise procedures. Medical headlamps, as an important auxiliary lighting tool, are widely used in these fields.

[0003] If the angle of illumination of a traditional headlamp needs to be adjusted (such as when focusing on different operating areas during surgery), medical staff often need to manually move the entire headband. This can not only easily interfere with head posture, but may also move the surgical cap or affect the sterile area, increasing the risk of operation.

[0004] Given the shortcomings of existing medical headlamps in terms of installation, disassembly, adjustment, maintenance, and disinfection, there is an urgent need to design a medical headlamp with a quick-release buckle structure and convenient adjustment to meet the efficiency and safety requirements of medical scenarios. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a medical headlamp with a quick-release buckle, achieved through the following specific technical means:

[0006] A medical headlamp with a quick-release buckle includes a headband and a housing. A lamp head is mounted on the front end of the housing, and a base plate is provided on the front end of the headband. A receiving groove is formed on the back of the housing, and a limiting strip is mounted on the base plate. The housing is fitted onto the base plate and the limiting strip through the receiving groove, allowing it to slide along the length of the base plate. A second sliding groove penetrating the housing is formed on the inner wall of the receiving groove. A sliding rod is slidably mounted within the second sliding groove, and a stop piece is fixedly connected to the sliding rod. The stop piece is slidably mounted within the receiving groove, and the surfaces of the stop piece that contact the base plate are both rough surfaces. A pin is provided on the sliding rod. A pressing rod is provided inside the housing, and a waist-shaped groove is formed on the inner wall of the pressing rod. The pin is located within the waist-shaped groove, and a spring is fixedly connected to the bottom end of the pressing rod.

[0007] Furthermore, the waist-shaped groove is inclined, and the pin is located on one side of the inner cavity of the waist-shaped groove, and can slide along the inner cavity of the waist-shaped groove.

[0008] Furthermore, a groove is provided on the upper surface of the outer shell, and the pressing rod is slidably installed in the groove. The pressing rod is connected to the bottom surface of the inner wall of the groove by a spring.

[0009] Furthermore, the top end of the pressing rod extends to the outer side of the slide groove for pressing the pressing rod.

[0010] Furthermore, there are two limiting strips, which are respectively disposed at the upper and lower ends of the substrate to limit the outer shell.

[0011] Furthermore, a battery for powering the lamp holder is provided inside the housing.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. It adopts a single-handed press-to-unlock design, allowing doctors to instantly unlock the lamp head position by pressing with only their thumb or index finger during surgery or operation. The lamp head position can be adjusted steplessly, and it will automatically lock after being released. The entire adjustment process is smooth and quick, without interrupting the current operation or requiring the assistance of another hand, thus improving work efficiency and user experience. The entire adjustment process does not require touching the headband, avoiding interference with the head posture of medical staff and the sterile area, making the operation more flexible.

[0014] 2. The surfaces of the stop plate and the substrate that are in contact with each other are designed with a rough surface. When locked, the two fit tightly together, which increases the friction to prevent the outer shell from accidentally sliding during medical operations, ensuring the stability of the lamp head's illumination position and preventing the illumination deviation from affecting the accuracy of the operation. The pressing rod is connected to the bottom surface of the inner wall of the slide through a spring. The elastic restoring effect of the spring can ensure that the stop plate always maintains a stable locked state, so there is no need to worry about the buckle loosening due to long-term use.

[0015] Third, the quick-release buckle structure, consisting of a pressing rod, sliding rod, stop plate, and spring, allows for installation of the outer shell and base plate (connecting headband) with no auxiliary tools, simply by pressing, fitting, and releasing. Disassembly is similarly straightforward; pressing the pressing rod releases the lock, allowing the outer shell to quickly detach from the base plate. This design significantly reduces installation and disassembly time, making it particularly suitable for headlamp replacement or sterilization procedures during surgical breaks, reducing waiting time in medical processes and improving work efficiency.

[0024] Example:

[0025] As attached Figure 1 To be continued Figure 3 As shown:

[0026] This utility model provides a medical headlamp with a quick-release buckle, including a headband 1 and a shell 3. The headband 1 is used to fix the entire headlamp on the user's head. A lamp head 7 is installed at the front end of the shell 3, and a base plate 2 is provided at the front end of the headband 1. The base plate 2 is fixed to the headband 1 by adhesive. A receiving groove 31 is opened on the back of the shell 3. A limiting strip 21 is installed on the base plate 2. The shell 3 is fitted onto the base plate 2 and the limiting strip 21 through the receiving groove 31 and can slide along the length direction of the base plate 2. The inner wall of the receiving groove 31 is provided with a sliding groove 33 that penetrates the shell 3. A sliding rod 5 is slidably installed in the sliding groove 33. A stop piece 52 is fixedly connected to the sliding rod 5. The stop piece 52 is slidably installed in the receiving groove 31. The surfaces of the stop piece 52 that are in contact with the base plate 2 are all rough surfaces, which greatly improves the friction when locking and prevents the shell 3 from accidentally sliding in critical scenarios such as surgery.

[0027] A pin 51 is provided on the slide rod 5, and a pressing rod 4 is provided inside the outer shell 3. A waist-shaped groove 41 is opened on the inner wall of the pressing rod 4, the pin 51 is located in the waist-shaped groove 41, and a spring 6 is fixedly connected to the bottom end of the pressing rod 4.

[0028] The waist-shaped groove 41 is inclined, and the pin 51 is located on one side of the inner cavity of the waist-shaped groove 41 and can slide along the inner cavity of the waist-shaped groove 41.

[0029] The upper surface of the outer casing 3 is provided with a sliding groove 32, and the pressing rod 4 is slidably installed in the sliding groove 32. The pressing rod 4 is connected to the bottom surface of the inner wall of the sliding groove 32 through a spring 6.

[0030] The top of the pressing rod 4 extends to the outside of the slide groove 32 and is used to press the pressing rod 4 for easy pressing operation.

[0031] There are two limiting strips 21, which are respectively set at the upper and lower ends of the base plate 2 to limit the outer shell 3 and prevent it from detaching from the outer shell 3. The limiting strips 21 and the base plate 2 are an integral structure and are made of plastic. They can be bent during use for easy wearing.

[0032] The housing 3 contains a battery for powering the lamp head 7 and a control board. The bottom of the housing 3 has a charging interface for charging the battery.

[0033] The working principle of this embodiment:

[0034] The user presses the top of the pressing rod 4 (the part extending to the outside of the slide groove 32) with their finger, causing the pressing rod 4 to slide downwards along the slide groove 32. At this time, the spring 6 at the bottom of the pressing rod 4 is compressed (storing elastic potential energy). Since the waist-shaped groove 41 on the inner wall of the pressing rod 4 is inclined, when the pressing rod 4 moves downwards, the inner wall of the waist-shaped groove 41 will generate a horizontal pushing force on the pin 51 embedded therein. Since the slide rod 5 can only slide along the slide groove 33 (horizontally), the pin 51, after being subjected to force, will drive the slide rod 5 to move away from the substrate 2 (outwards), thereby causing the stop piece 52 at one end of the slide rod 5 to slide outwards simultaneously, disengaging from the contact state with the substrate 2 (at this time, the receiving groove 3) 1. Space is reserved inside for mounting the substrate 2); the outer shell 3 is fitted onto the substrate 2 and the limiting strip 21 from the edge of the substrate 2 through the receiving groove 31 on the back (the limiting strip 21 prevents the outer shell 3 from detaching); the pressing rod 4 is released, the compressed spring 6 releases its elastic potential energy, and pushes the pressing rod 4 to return to its original position along the slide groove 32. The waist-shaped groove 41 moves upward with the pressing rod 4, generating a reverse horizontal pulling force on the pin 51, which drives the slide rod 5 and the stop piece 52 to return to their original position towards the substrate 2. Finally, the rough surface of the stop piece 52 is tightly attached to the surface of the substrate 2; the outer shell 3 and the substrate 2 are locked by friction. The installation is complete. At this time, the lamp head 7 can be powered by the battery inside the outer shell 3 and used normally.

[0035] When the user needs to adjust the illumination angle of the lamp head 7 (such as focusing on different areas during surgery), there is no need to disassemble or adjust the headband 1. The adjustment can be made directly through the following steps: Press the top of the pressing rod 4 again and repeat the above steps. The spring 6 is compressed, and the stop plate 52 moves outward with the sliding rod 5, disengaging from the substrate 2. The locked state of the outer shell 3 is released. At this time, the outer shell 3 can slide freely along the length of the substrate 2. The user pushes the outer shell 3 to the appropriate position (the illumination angle of the lamp head 7 meets the requirements). Release the pressing rod 4, the spring 6 returns to its original position, and the stop plate 52 re-attaches to the substrate 2. The outer shell 3 is locked again, and the position adjustment is completed. The whole process can be done without interrupting use, making it convenient to operate.

[0036] During disassembly, the top of the pressing rod 4 can be pressed to move the stop piece 52 outward with the sliding rod 5, disengaging it from the substrate 2 and releasing the lock of the outer shell 3; along the edge direction of the substrate 2, the outer shell 3 is pulled outward, and the outer shell 3 gradually disengages from the substrate 2 and the limiting strip 21 through the receiving groove 31 until it is completely separated from the substrate 2, and the disassembly is completed.

[0037] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
