DETAILED DESCRIPTION
[0022] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0023] Example: Figure 1-Figure 5As shown, the utility model provides an adjustable rotating headlamp, which structure includes an inner shell 1 equipped with a lamp tube assembly and an outer shell 4 nested outside the inner shell 1 for controlling the movement of the light assembly 2, and also includes a base worn on the head, wherein the base is provided with power supply parts such as batteries, the inner shell 1 is installed on the base and worn together with the base, the light assembly 2 includes a lens 21, a movable seat 23 and a wick 22 installed on the movable seat 23, the lens 21 is fixedly installed on the front end of the inner shell 1 through a mounting ring 3, the wick 22 includes a circuit board, a lamp bead installed on the circuit board for emitting light and a light cover surrounding the lamp bead, the circuit board has structures such as wires or contact electrodes, and the inner shell 1 is installed to the headlamp. After being mounted on the base, it is used to connect with the battery in the base to power the lamp beads. A guide groove 1a is provided on the inner shell 1 along the axial direction of the inner shell 1. An actuated block 24 is provided on the movable seat 23 and the actuated block 24 is engaged in the guide groove 1a. The movable seat 23 is axially moved in the inner shell 1 by the actuated block 24 to change the distance with the lens 21. It is known to those skilled in the art that the lens 21 usually adopts a convex lens. By adjusting the distance between the movable seat 23 and the lens 21, the focal length of the light of the lamp beads in front of the lens, or the position where the light source is concentrated, is adjusted from focusing to flooding. In use, the light state with a long focal length and not in a small range in front of the user is called flooding.
[0024] In order to make the movable seat 23 move, a plurality of guide strips 4b inclined to the axis of the shell 4 are arranged around the inner wall of the shell 4, and the actuated block 24 is provided with an actuated channel 24a, and the actuated channel 24a has at least two side limit structures and these two side surfaces are in contact with the side surfaces of the guide strip 4b. The movable seat 23 is axially movable in the guide groove 1a under the rotation of the shell 4 through the actuated channel 24a and the guide strip 4b, so as to adjust the distance between the movable seat 23 and the lens 21. It should be noted that in the projection of the guide strip 4b on the circumference of the front surface of the shell 4, the angle between the two ends of the guide strip 4b and the center of the circle is 90°.
[0025] -120°; the length of the guide strip 4b in the axial direction of the axis of the shell 4 is greater than or equal to the length of the guide groove 1a. It can be seen that when the rotating shell 4 rotates 90°-120°, the driven block 24 will be driven by the guide strip 4b to travel along the guide groove 1a for a section of the length of the guide groove 1a, thereby covering the lighting state from spotlight to floodlight and reducing the number of rotations. In this embodiment, a parameter is also introduced, that is, the angle between the connecting line at both ends of the guide strip 4b and the axis of the shell 4 is between 45°-65°, thereby making it more convenient to plan the length of the guide groove 1a, so that the guide groove 1a can be set to a sufficient active length according to the needs of technicians in this field.
[0026] As for the moving seat 23, the moving seat 23 and the actuated block 24 can be integrally arranged or separately arranged. In the present embodiment, the actuated block 24 is detachably mounted on the moving seat 23. Since the guide bar 4b of the housing 4 is inclined, the rotation of the housing 4 is converted into a linear motion of the actuated block 24 in the guide groove 1a when the actuated block 24 is driven to move. Therefore, the guide bar 4b and the actuated block 24, and the actuated block 24 and the guide groove 1a are usually matched and driven by surface contact and friction, which makes it feel a little blocked when used. Therefore, a sliding assembly 25 or a sliding structure or both are provided on the actuated block 24, which is used to reduce the resistance of one or both sides when the guide bar 4b and the guide groove 1a are cross-clamping and rubbing the actuated block 24, so as to make the adjustment smoother.
[0027] Specifically, the sliding assembly 25 includes a fixed seat 251 and a movable seat 253 connected to the fixed seat 251 through a spring 254, and running wheels 252 are provided on the outer sides of the fixed seat 251 and the movable seat 253; the interior of the passive block 24 is provided with an inner through cavity 24b with two sides passing through, the fixed seat 251 is installed in the inner through cavity 24b, and the running wheel 252 extends from the inner through cavity 24b and contacts the inner wall of the guide groove 1a, and the spring 254 provides elastic force on the fixed seat 251 to drive the running wheel 252 on the movable seat 253 to push against the inner wall of the guide groove 1a, so that the running wheels 252 on both sides can contact the inner wall of the guide groove 1a, ensuring smooth movement;
[0028] In this embodiment, the sliding structure includes a clamping wheel 26, which is installed at the top of the actuated block 24. The clamping wheel 26 is provided with at least two clamping wheels 26, and the channel between the two clamping wheels 26 is the actuated channel 24a. The two clamping wheels 26 are the limiting structures on the two sides, and the guide bar 4b moves between the clamping wheels 26, thereby ensuring that the guide bar 4b and the actuated block 24 are in smooth contact.
[0029] In this embodiment, a metal ring is provided on the outer surface of the inner shell 1, and a magnetic strip is provided on the inner wall of the outer shell 4 and is attracted to the metal ring on the outer surface of the inner shell 1, so as to stabilize the position of each adjustment while ensuring smooth sliding.
[0030] In the specific implementation, the lamp bead is started to emit light, and the outer shell 4 is rotated. The guide bar 4b of the outer shell 4 and the clamping wheel 26 of the actuated block 24 are against each other to give the actuated block 24 an inclined force. The actuated block 24 converts the inclined force applied by the guide bar 4b in the guide groove 1a into a straight line motion outward along the guide groove 1a, so that the movable seat 23 approaches the lens 21, allowing the light to be focused not far in front of the lens 21, and spotlighting is performed on the area to be illuminated. The outer shell 4 and the inner shell 1 are magnetically attracted to stabilize the position of each adjustment. When strong light is not needed for targeted irradiation, the outer shell 4 is rotated in the opposite direction, and the movable seat 23 moves backward away from the lens 21, so that the transmitted light forms a floodlight state in front of the user.
[0031] Embodiment 2: On the basis of embodiment 1, the rear end of the inner shell 1 is in the shape of a stepped cylinder with a diameter larger than the front end. The mounting ring 3 installed at the front end of the inner shell 1 has an outer diameter larger than the front end of the inner shell 1, and cooperates with the rear end of the inner shell 1 to form an inwardly recessed annular groove at the front end of the inner shell 1. An inwardly contracting inner limit ring 4a is provided on the inner side of the outer shell 4, and the inner limit ring 4a is nested and engaged in the annular groove. During installation, the outer shell 4 is first nested on the inner shell 1, and then the mounting ring 3 is installed to the front end of the inner shell 1, so that the mounting ring 3 can fix the lens 21 while limiting the outer shell 4, and the outer shell 4 can be installed simultaneously.
[0032] Embodiment 3: On the basis of embodiment 1, the front cross-section of the guide strip 4b is trapezoidal in shape and the width of the end close to the inner wall of the outer shell 4 is greater than the width of the end close to the center of the outer shell 4. The clamping wheel 26 is truncated cone-shaped and cooperates with the guide strip 4b, so that the clamping wheel 26 and the guide strip 4b can be more closely matched, and the movable seat 23 can be embedded in the guide strip 4b of the outer shell 4 during the initial installation, so that the adjustment feel is thicker rather than loose.
[0033] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
