Specific implementation mode

The utility model is described in further detail below in conjunction with attached drawing embodiment.

As shown in Figures 1 to 5, in the present embodiment, the flashlight of the one hand fast zoom, including lamp adapter assembly 1 and cylinder Body 2,2 head of cylinder are provided with illuminator 4, and the battery 21 that can be formed into a loop with illuminator 4 and switch are additionally provided in cylinder 2 23, condenser lens 111 is provided on lamp adapter assembly 1, and lamp adapter assembly 1 is set in the head of cylinder 2 and can be in the band of pushing component 9 Along the axial direction sliding of cylinder 2 under dynamic, to adjust the distance between illuminator 4 and condenser lens 111.

In the present embodiment, above-mentioned lamp adapter assembly 1 include gland 11, sliding connector 12, connector sleeve 3 and in gland 11 The spacing ring 13 of wall fitting, sliding connector 12 are connected by connector sleeve 3 with gland 11,12 head top pressure limit of sliding connector Position ring 13 limits condenser lens 111 on gland 11, and 12 tail portion of sliding connector is set on the head of cylinder 2 and can be opposite The axial sliding of cylinder 2 has gear along 11a specifically, 11 inner wall of gland extends internally, and 111 upper periphery of condenser lens is laterally outer Be extended with protrusion 11b, sliding connector 12 by spacing ring 13 by protrusion 11b top pressures in gear along 11a with by condenser lens 111 It is limited in gland 11.

In order to realize that above-mentioned shuffle effect, the head of the present embodiment middle cylinder body 2 have the connection for inside contracting and raising up Portion 22 forms lower shoulder block 22b between interconnecting piece 22 and the head of cylinder 2, illuminator 4 is set on installation part 5, under installation part 5 Portion is threaded in interconnecting piece 22, and the peripheral side protrusion interconnecting piece 22 on the top of installation part 5 is to form upper shoulder block 22a, sliding Interior omoplate 121 is formed on 12 inner hole wall of connector, interior omoplate 121 is between upper shoulder block 22a and lower shoulder block 22b, and upper gear Shoulder 22a and lower shoulder block 22b forms limit up and down to interior omoplate 121.

The sliding of lamp adapter assembly 1 is realized by operating pushing component 9, and wherein pushing component 9 includes being set in sliding Promotion ring 91 on connector 12 and the push button 92 being arranged on the promotion ring 91,12 periphery wall of sliding connector are outward extended with Step 122 pushes the limit of ring 91 between the step 122 and connector sleeve 3, is provided on push button 92 to anti-skidding lines.

Flashlight in the present embodiment is both provided with sealing ring in many places, wherein between sliding connector 12 and installation part 5 It is provided with the first sealing ring 6, the groove of accommodating first sealing ring 6 is further opened on 5 periphery wall of installation part, connector sleeve 3 passes through spiral shell Line is fixedly connected with sliding connector 12, gland 11 respectively；It is formed by third sealing ring 8 between gland 11 and connector sleeve 3 It is tightly connected；Installation part 5 and interconnecting piece 22 are threadably secured connection, pass through the second sealing between installation part 5 and interconnecting piece 22 Circle 7, which is formed, to be tightly connected, wherein the setting of the first sealing ring 6, can not only play the role of waterproof sealing, while in lamp adapter assembly In the state that 1 slides relative to cylinder 2, positioned at sliding connector 12 and first fitted closely between 11a and with the two is kept off Sealing ring 6 also plays the effect of sliding damping, will not just generate prodigious displacement because of the promotion of little force, avoid to inside Part causes to damage；Lamp adapter assembly 1 and cylinder 2 can be prevented in the state that lamp adapter assembly 1 is static relative to cylinder 2 simultaneously Between excessively loosen, focal length changes automatically when avoiding unattended, keeps the stability used.

In use, one hand is only needed to hold cylinder 2, with thumb press push button 92, push button 92 is stirred forward or backward, at this time Push button 92 can drive sliding connector 12 to be moved axially relative to cylinder 2, be connected with sliding connector 12 by connector sleeve 3 Lamp cap 11 can generate displacement together, and the condenser lens 111 on lamp cap 11 will be therefore relative to mounted on cylinder 2 Axial sliding occurs for the illuminator 4 in portion, and then completes the adjusting of focal length.
