Embodiment 1

[0089] Such as figure 1 As shown, the focusing flashlight includes a lamp head assembly 3, a connecting ring 6, a cylinder body 1, a switch assembly 16 and a tail cap 11 that are visible from the appearance in an assembled state. Further, as shown in FIG. Figure 2A , 2B As shown, it also includes an internal luminous body 2, a bracket 4, an elastic member 5, a guiding claw 7, a connecting seat 8, a conductive contact 9, a sealing ring 10, a supporting spring 12, a conductive ring 13, and a first conductor 14. The second conductor 15, wherein:

[0090] The lamp head assembly 3 is composed of a light-transmitting plate 3A, a reflective bowl 3B, an undulating part 3C, a cylindrical body 3E, an adjustment structure 3F, and a protective cover 3G: the cylindrical body 3E is an integral structure made of plastic (such as injection molding), Therefore, it is circular in cross-section (cf. image 3 ), there is a head flange 3E3 at the front end of the cylindrical main body 3E, and ...

Embodiment 2

[0105] Based on the detailed description of Embodiment 1, this embodiment only illustrates the differences from Embodiment 1, such as Figure 7 , 8 As shown, in order to convert the rotation of the lamp head assembly 3 into the forward and backward movement of the illuminant 2, in this embodiment, the abutment portion 3D is provided on the rear side of the reflective bowl 3B, and the corresponding undulating portion 4A is provided on the bracket 4. At this time, The abutment portion 3D and the ring wall 4D of the support cooperate with each other as an adjustment structure to prevent the swing of the support 4 during the focusing process and cause the illuminant 2 to shift. The focusing process of this structure is the same as that of Embodiment 1, and will not be repeated here.

Embodiment 3

[0107] Based on the detailed description of Embodiment 1, this embodiment only illustrates the differences from Embodiment 1, such as Figure 9As shown, the convex lens 3J is used as the light concentrating element, and it has the functions of the light-transmitting plate 3A and the reflective bowl 3B of Embodiment 1 at the same time, that is, it is used for light transmission and can protect the illuminant 2 at the same time. Similarly, the convex lens 3J and The cylindrical main body 3E is sealed and fitted (such as being made into one body) to form a lamp head assembly which itself has a good waterproof sealing effect, and has a stronger waterproof sealing effect; since the convex lens 3J can only concentrate the emitted light, in order not to lose the light , this structure is especially suitable for light emitters such as LEDs that emit light in a specific direction. Further, on this basis, a reflective bowl 3B can also be provided inside the convex lens 3J so as to be su...

Abstract

The invention provides a focusing torch which pertains to an illuminant tool. Defects of complex structure and being hard to guarantee water resistance exist in the prior art. The invention is characterized in that: an illuminant is arranged on a bracket which is moved forwards and backwards to be restrained at the front part of the torch body and is supported with an elastic piece; an adapter ring is connected on a bulb holder component which is connected to the front end of the torch body through the adapter ring and covered on the illuminant; a corresponding heaving part and a corresponding supporting part are respectively positioned in the bulb holder component and on the bracket. The bracket is driven to bring the illuminant to move forwards and backwards by the relative rotation of the supporting part on the corresponding heaving part to change the relative position between the illuminant and a reflector, thus realizing the purpose of focusing. The structures of the heaving part and the supporting part are simple and the positions thereof do not damage the integrity of the torch body and the bulb holder component, thereby being favorable for realizing the water-proof sealing between the bulb holder component and the torch body in structure.

Description

technical field [0001] The invention belongs to lighting appliances, specifically a focus-adjustable torch, which provides structural guarantee for waterproofing and broadens the application occasions of the torch. Background technique [0002] There are many types of flashlights in the prior art. The more traditional structure is a flashlight made of metal material, including a lamp cap, a barrel, and a tail cap. A battery is installed in the barrel, a light bulb is installed at the front end of the barrel, and the lamp cap is directly connected by a screw thread. Cover the bulb at the front of the barrel. When focusing, turn the lamp head directly to change the relative position of the reflective bowl of the lamp head and the bulb. Since the flashlight of this structure is made of metal, in order not to affect the appearance (such as the flatness of the connection part), the structure of the lamp head and the cylinder body can be made relatively thin, and the connection th...
