Abstract

The utility model relates to a sail frame pivot seat, which comprises a stationary seat, a sail frame inner cover and a sail frame outer cover. The stationary seat is provided with an inserting head, a teeth ring and a pair of ring grooves. The inserting head is used for making the sail frame pivot seat inserted on the inserting seat of a baby carriage frame. The sail frame inner cover and the sail frame outer cover are respectively provided with a sail frame bow arm and a gear, and the teeth rings for the gear inserting to the stationary seat are used for fixing in a graduation manner. The teeth ring is provided with a nick, when the sail frame inner cover and the sail frame outer cover rotate, the nick of the teeth ring can make the teeth ring extend in an elastic manner to make the gear rotate in relation to the teeth ring. The outside surrounding of the teeth ring of the stationary seat is provided with a pair of ring grooves to place a pair of elastic contracting rings, and the elasticity of the elastic contracting ring tightly binds the teeth ring to make the teeth ring grip tightly the gear of the sail frame inner cover and the sail frame outer cover, preventing the gear to produce elasticity exhausting during repeated elasticity distorting, and the shaking or noise when the teeth ring extends or contracts are eliminated.

Description

Sail frame pivot seat

Technical field

The utility model relates to a kind of pivot seat of sail frame bow arm, relates in particular to a kind of sail frame pivot seat that utilizes an elastic shrinkage circle to prevent assembly generation elastic fatigue.

Background technology

Baby stroller is the vehicle that design is taken to the infant.Because baby stroller uses chance height out of doors, thus need the sunshade ceiling, to keep out the sunlight of direct irradiation.

For making things convenient for folding, the sunroofs skeleton of perambulator needs and can launch and fold.As the sunshade ceiling mechanism that US Patent is taken off for No. 4378946, be to support the usefulness that a fabric is done sunshade with " U " font bow arm.The two ends of bow arm are articulated in respectively on the handle pipe of perambulator, drive fabric by the pivot that bends arm and launch or fold.

But present calibration location, and the sail frame bow arm pivot seat mechanism that can apply to the sunshade ceiling had a variety ofly, and but major part is all too complicated.Not only make up time-consuming, extremely many for production quantity manufacturer, its cost and assembly cost are not the right influence of milli.

The utility model content

Based on the deficiencies in the prior art, but the purpose of this utility model provides a kind of calibration location, can apply to the sunshade ceiling again, and is beneficial to stock production, quick assembling and guarantees the sail frame pivot seat that the pivot seat does not become flexible chronically.

For achieving the above object, the technical solution of the utility model is: a kind of sail frame pivot seat is provided, and described sail frame pivot seat comprises: a permanent seat is provided with a connection-peg and a gear ring; One sail frame inner cap is provided with a sail frame bow arm Connection Block and a gear, and this gear inserts to be made pivotable calibration in the gear ring of this permanent seat and fix; And a sail frame enclosing cover, being provided with a sail frame bow arm Connection Block and a gear, this gear inserts to be made pivotable calibration in the gear ring of this permanent seat and fixes.

Preferable, the gear ring of described permanent seat has some roads breach, and when sail frame inner cap and the rotation of sail frame enclosing cover, the breach of gear ring can flexibly be opened gear ring outward and is allowed that the gear mesh gear ring relatively rotates.

Preferable, the gear ring periphery of described permanent seat also has a pair of annular groove, with ccontaining a pair of elastic shrinkage circle, the elasticity of elastic shrinkage circle is tightened gear ring, make gear ring sting the gear of tight sail frame inner cap and sail frame enclosing cover, prevent that gear from producing elastic fatigue in the elastic deformation repeatedly, and can eliminate gear ring for outer open or condensation in the vibrations or the sound.

The utility model is compared with prior art since form simple, so but the at high speed assembling be beneficial to stock production, and guarantee that chronically the pivot seat does not become flexible.

The specific embodiment

As shown in Figure 1, general perambulator has a collapsible skeleton 01, establishes a plug socket 02 on the described skeleton 01, for the sail frame pivot seat 03 of the present utility model of pegging graft, prop up the

bow arm

05,06 of sail body 04 in order to connection, make the opening and closing amplitude of sail body 04 can moving then adjust with

bow arm

05,06.

As shown in Figures 2 and 3, sail frame pivot seat 03 of the present utility model comprises a permanent seat 31, a sail frame inner cap 32, a sail frame enclosing cover 33 and a pair of

elastic shrinkage circle

34,35.

As shown in Figure 2, the permanent seat 31 of sail frame pivot seat 03 of the present utility model is provided with a connection-peg 311, a gear ring 312 and a pair of annular groove 313.The plug socket 02 that utilizes connection-peg 311 to be plugged on the perambulator skeleton 01 for sail frame pivot seat 03, annular groove 313 is located at the periphery of gear ring 312, comes ccontaining

elastic shrinkage circle

34,35 to make with this and flexibly tightens gear ring 312.

Sail frame inner cap 32 and sail frame enclosing cover 33 are provided with a sail frame bow arm Connection Block 321,331 and a gear 322,332 separately, and the gear ring 312 that utilizes gear 322,332 to insert permanent seat 31 is made a pivotable calibration and fixed.

As shown in Figure 4, described gear ring 312 is provided with some breach 314, when sail frame

inner cap

32 or 33 rotations of sail frame enclosing cover, because gear ring 312 is provided with breach 314, allows that 322,332 pairs of gear rings 312 of gear relatively rotate so can make flexibly outer of gear ring 312.

As shown in Figure 5, the effect of described elastic shrinkage circle 35 is in order to the strength of gear ring 312 condensations to be provided, to enable tightly to sting the gear 322,332 of sail frame inner cap 32 and sail frame enclosing cover 33.

The utility model is to utilize elastic shrinkage circle 34 to prevent that gear ring 312 from elastic fatigues taking place, and with this suppress eliminates gear ring 312 in outside or condensation in the vibrations and the sound.Elastic shrinkage circle 34 can be selected the rubber manufacturing for use, such as (Thermplastic Rubber TPR) makes, in order to prevent that gear ring 312 is with climate change heat expansion, shrinkage and loss of function with thermoplastic rubber.Extremely shown in Figure 5 as Fig. 2, the better one, the implementer can be in permanent seat 31 outstanding protuberances 315, the slewing area of restriction sail frame inner cap 32 and/or sail frame enclosing cover 33.In addition, also can establish a flange 323,333 respectively, enable to limit further the slewing area of sail frame inner cap 32 and sail frame enclosing cover 33 in the outer rim of sail frame inner cap 32 and sail frame enclosing cover 33.

Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
