Embodiment

Shown in Fig. 1, it is the stereogram of embodiment's of the present utility model air compressor.The air compressor of the present embodiment comprises bracket component 1, gas holder 6, movement 4 and control unit 5; Bracket component 1 comprises retractable handle 2 and locking mechanism 3.

With reference to Fig. 2 to Fig. 4, bracket component 1 also includes the main part 11 that is arranged on bracket component 1 rear side, and main part 11 is roughly two pipes that are parallel to each other, and it includes a hollow inner chamber 112; Locking mechanism 3 is sheathed on the upper end of main part 11, and this locking mechanism 3 includes fixing frame 31, slider 32, extrusion 33, cam toggle 34 and bearing pin 35.

With reference to Fig. 4 to Fig. 7, retractable handle 2 is a U-shaped tubular element, in its underpart, square groove 21 is set, slider 32 is set in the lower end of retractable handle 2, the blockage 321 being arranged on slider internal surface can insert in corresponding square groove 21 on retractable handle 2, thereby slider 32 is fixed on to the lower end of retractable handle 2; Slider 32 is housed in the inner chamber 112 of main part 11 slidably completely simultaneously.The pipe diameter size of retractable handle 2 is slightly more a little bit smaller than the internal diameter of main part 11 in addition, and therefore the lower end of retractable handle 2 also can be contained in the inner chamber 112 of main part 11, has realized retractable handle 2 and has partly been contained in main part 11 slidably.With reference to Fig. 5, fixing frame 31 is roughly a cylindrical shape, and its inside is provided with inner ring 314, is also provided with the hinge portion 312 being connected with bearing pin 35 on its outer surface, and 312 centers, hinge portion are provided with pin-and-hole 313 that can be pivotally connected with bearing pin 35.Above-mentioned inner ring 314 can be contained in the inner chamber 112 of main part 11 simultaneously and slide and be coupled on the outer surface of retractable handle 2, the size of this inner ring 314 is suitable with the slider 32 that is set in retractable handle 2 lower ends, therefore in the time of retractable handle 2 upward sliding, slider 32 can finally be resisted against on the inner ring 314 of fixing frame 31, thereby prevents that retractable handle 2 from deviating from from the inner chamber 111 of main part 11.On fixing frame 31, be also provided with in addition second and accommodate mouth 311, in the time that inner ring 314 is contained in the inner chamber 112 of main part 11, above-mentioned second accommodate mouthfuls 311 just in time with first the accommodating mouthfuls 111 and align of upper end portion that is arranged on main part 11, and this first is accommodated mouthfuls 111 and second and accommodates mouthfuls 311 sizableness, now, extrusion 33 can be contained in first simultaneously and accommodate mouthfuls 111 and second and accommodate in mouthfuls 311, and can accommodate mouth 111 and second along first and accommodate mouthful 311 passages slips that form, also fixing frame 31 can be fixed on to the upper end portion of main part 11, prevent sliding up and down or rotation mutually between fixing frame 31 and main part 11.On cam toggle 34, be provided with eccentric part 341, center hole 342 and toggle 343.Center hole 342 can be pivotally connected with bearing pin 35, thereby make cam toggle 34 and the rotatable connection of fixing frame 31.

With reference to Fig. 8 and Fig. 9, carrying out rotating cam toggle 34 by the toggle 343 on cam toggle 34 makes to be formed with the first unlocked position and the second locked position between itself and fixing frame 31, this cam toggle 34 is in the time of the first unlocked position, be arranged at eccentric part on cam toggle 34 341 and be contained in first and accommodate mouthfuls 111 and second extrusions 33 of accommodating in mouthfuls 311 and mutually depart from, between extrusion 33 and retractable handle 2, also mutually depart from simultaneously, now retractable handle 2 is in releasing orientation, can relative sliding between itself and main part 11.When rotation toggle 343 makes in the process of cam toggle 34 in the second locked position, eccentric part 341 progressively push against extrusion 33 make its along first accommodate mouthfuls 111 and second accommodate mouthful 311 passages that form to retractable handle 2 near until be mutually close to, when cam toggle 34 is during in the second locked position, extrusion 33 and retractable handle 2 are closely abutted together, thereby retractable handle 2 is locked.

Pass through said mechanism, retractable handle 2 can slide up and down along main part 11 in bracket component 1 according to different users' demand, when adjust to satisfy the demands the moment by rotation toggle 343 make cam toggle 34 in the second locked position, thereby retractable handle 2 is locked, the scalable part of retractable handle 2 can be contained in the main part 11 of bracket component 1 like this, profile is more attractive in appearance, simultaneously can meet retractable handle 2 again and be adjusted to the demand of different heights.
