Specific embodiment

With reference to the accompanying drawings and examples this utility model is further described, but is not intended as to this utility model The foundation limiting.

Embodiment of the present utility model：A kind of adjustable seat pocket of baby carriage, as shown in accompanying drawing 1-7, includes Back pocket body 1, back pocket body 1 is connected with horizontal pocket body 2, and horizontal pocket body 2 is connected with leg guard 23 through tuning mechanism 22, back pocket The outside of body 1 is also hinged with deep bead 4 head end through hinge 3, air vent 5 is distributed with back pocket body 1；On described deep bead 4 Stopple 6 be distributed with, stopple 6 is corresponded with the position of air vent 5, deep bead 4 end be provided with telescoping mechanism 7；Described stretches Contracting mechanism 7 includes sleeve 9, and sleeve 9 is connected with back pocket body 1 through support 8, is additionally provided with elastic bar 10, elastic bar in sleeve 9 10 are connected with deep bead 4, and deep bead 4 is fixed with spring fixed column 11, and spring fixed column 11 is through coil tension spring 12 and spring base Seat 13 connection, spring seat 13 is fixed on back pocket body 1；It is additionally provided with locating button 14 on described elastic bar 10；Described Keep out the wind location hole 15 and ventilation location hole 16 are also sequentially provided with the barrel of sleeve 9, sleeve 9 are also associated with elastic driving lever 17, The head end of elastic driving lever 17 is provided with clinching 18, and clinching 18 is corresponding with the position of the location hole 15 that keeps out the wind；The described mechanism 22 that tunes wraps Include rotating shaft 24, the two ends of rotating shaft 24 are respectively connected with benchmark internal gear 25, are provided with external gear 26, external gear 26 in benchmark internal gear 25 An end face be connected with the end face of benchmark internal gear 25 through spring 27, another end face of external gear 26 with adjust internal gear 28 End face connect, adjust internal gear 28 with regulation button 29 be connected；Described regulation button 29 is provided with limit buckle 30, limit buckle 30 are connected with the end face adjusting internal gear 28；Described benchmark internal gear 25 is fixed on horizontal pocket body 2；Described regulation internal tooth Wheel 28 is fixed on leg guard 23.

When temperature is higher, depresses clinching 18, be lifted off, by being in the locating button 14 keeping out the wind in location hole 15, the location hole that keeps out the wind 15, under the elastic force effect of coil tension spring 12, deep bead 4 turns clockwise (on the basis of Fig. 1 position) along hinge 3, during rotation, Elastic bar 10 is promoted along sleeve axis 9 direction, until locating button 14 snaps in ventilation under the effect of elastic bar 10 elastic force Location hole 16, now deep bead 4 stop the rotation, stopple 6 leaves air vent 5, increases ventilation effect；When temperature is relatively low, pressure Elastic bar 10 head end, locating button 14 slips away ventilation location hole 16 and the axis along sleeve slides, until snap in the location hole that keeps out the wind In 15, in sliding process, elastic bar 10 makes deep bead 4 along hinge 3 rotate counterclockwise and compresses coil tension spring 12, until hole Air vent 5 is blocked by plug 6, reduces ventilation effect.

When needing to adjust leg guard 23, press regulation button 29, adjust button 29 and promote external gear 26 along to rotating shaft 24 Axis direction moves, and now the gear teeth of external gear 26 are separated with the gear teeth adjusting internal gear 28 and spring 27 compresses, and the gear teeth separate After leg guard 23 can be made to rotate to adjust angle.After adjusting to proper angle, release adjusts button 29, the spring 27 of compression Reply, promote external gear 26 along rotating shaft 24 axis direction adverse movement, and make the gear teeth and the regulation internal gear 28 of external gear 26 Gear teeth meshing, the now gear teeth of benchmark internal gear 25 and the gear teeth gear teeth meshing with external gear 26 simultaneously adjusting internal gear 28, Leg guard 23 is blocked, completes angular adjustment.

Aforesaid elastic bar 10 is connected with deep bead 4 through roller 19.By this structure, make elastic bar 10 in deep bead When sliding on 4, its sliding friction is changed into rolling friction, reduces its frictional force, increases the service life.

Aforesaid elastic bar 10 is provided with position-arresting disk 20；The inwall of described sleeve 9 is provided with spacing ring 21.By this Structure, while locating button 14 snaps in ventilation location hole 16, spacing ring 21 just withstands position-arresting disk 20, prevents because of locating button 14 The too fast situation having not been able to snap in ventilation location hole 16 in time and making elastic bar 10 skid off sleeve 9 of sliding occurs, thus increasing Stability of the present utility model.
