The specific embodiment

Below in conjunction with accompanying drawing, the present invention is further illustrated.

A kind of child safety seat connection structure of the present invention, comprise chair body 1 andseat support 2, the upper level of describedseat support 2 is provided withmajor axis 21, the upper surface ofseat support 2 bottoms is provided with two symmetrically arrangedslideways 3, the bilateral symmetry of described chair body 1 top rear face is provided withlatch hook 11,latch hook 11 is the setting of U-shaped structure, and the U-shaped recess oflatch hook 11 is enclosed within on the two ends ofmajor axis 21; Chair body 1 bottom surface is provided with control apparatus, and control apparatus andslideway 3 are connected, and control apparatus can move forward and backward between twoside slideways 3.

On describedslideway 3, have thechute 31 of arc, the upper limb place ofchute 31 has thelimited mouth 32 at some intervals; Described control apparatus comprisesslide rail 41, regulatingplate 42,slide block 45, pivot shaft 43 and adjustingshaft 44, describedslide rail 41 is provided with supported hole A411 and adjustment hole A412, described regulatingplate 42 is provided with supported hole B421 and adjustment hole B422, described bolster 43 is located in supported hole A411 and supported hole B421, pivot shaft 43 two ends are flexibly connected withchute 31 byslide block 45, described adjustingshaft 44 is located in adjustment hole A412 and adjustment hole B422, and adjustingshaft 44 two ends andlimited mouth 32 are connected.

Above-mentioned parts are agent structure of the present invention.

Described regulatingplate 42 tail ends are provided withextension spring 46, and describedextension spring 46 upper ends are connected with slide rail 41.Describedslideway 3 front portions are provided with limitingstopper 62, andchute 31 front ends are provided with locatingdowel pin 61, and described locatingdowel pin 61 is flexibly connected with limitingstopper 62, between locatingdowel pin 61 and limitingstopper 62, are provided with stage clip 63.The height of described adjustment hole A412 is more than the twice of adjustingshaft 44 diameters.

Principle of work: when chair body 1 andseat support 2 are fixing,major axis 21 two ends are by the front and back position locking oflatch hook 11,chute 31 limits the upper and lower displacement ofslide block 45,extension spring 46 is upwards dug regulatingplate 42 rear ends, make adjustingshaft 44 be arranged inlimited mouth 32, thereby limit the moving forward and backward of regulating mechanism,slide block 45 and adjustingshaft 44 and then the relative position of chair body 1 bottom andseat support 2 is fixed by regulatingplate 42 andslide rail 41.

In the time adjusting the angle of chair body 1relative seat support 2, regulatingplate 42 front ends are upwards dug, adjustingshaft 44 departs fromlimited mouth 32 downwards, pull chair body 1 bottom to carry out front and back adjustment, thelatch hook 11 on chair body 1 top thereupon extendingshaft 21 moves, relieving regulatingplate 42 after angular adjustment completes,extension spring 46 drives regulatingplate 42 rear ends upwards to reset, and adjustingshaft 44 snaps in correspondinglimited mouth 32 and again completes locking.

Whenslide block 45 is during forward to locatingdowel pin 61 place inchute 31, reach the limit of adjusted position, outwards pull open locatingdowel pin 61,slide block 45 moves to chute 31 foremost,latch hook 11 exceeds range and departs frommajor axis 21, and now chair body 1 can outwards be dug, and chair body 1 departs fromseat support 2.

The above is only preferred embodiments of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
