Abstract

The utility model relates to a safe and joint-clamping-avoidance device used for folding a baby carriage, which at least comprises a joint group, a sunken surface and a raised surface, wherein the joint group is mainly characterized in that side walls are respectively formed on the two sides of a combination block, shaft holes are formed on the two side walls in a penetrating manner, a combination groove is formed between the two side walls, a movable block is further arranged in the combination groove to enable a pivot to pass through the shaft holes and a through hole on the movable block, so that the movable block can rotate by taking the pivot as a shaft center. The sunken surface can be arranged on the outer wall of the combination block between the two side walls; and the raised surface can be arranged on the outer wall of the movable block in a matching manner. Therefore, when the movable block is pivoted on the combination block, the movable block rotates by a certain angle and is closely overlapped with the combination block, the raised surface can be exactly and relatively matched with the sunken surface, and then the joint group is bent, so that human organs can not stretch into a clearance between the combination block and the movable block, and the safety effect of clamping avoidance is achieved.

Joint set, formed by combined block, pivot end A, sidewall, axis hole, engagement groove, movable block, perforation, pivot, pivot end B, combined block one end place is provided with pivot end A, also be formed with sidewall on the combined block dual side-edge respectively, this two sidewall then all has the axis hole that runs through, and between described two sidewalls and be formed with engagement groove; One can be placed in the movable block in the engagement groove, and this movable block is provided with a perforation, described axis hole is communicated with into a through hole with this perforation, one as the movable block center of rotation and make movable block be articulated in pivot on the combined block, runs through this axis hole and perforation simultaneously, and one end place also is provided with pivot end B in movable block;

Described concave face be arranged at combined block with movable block institute corresponding outer wall on;

Described raised face is arranged on the corresponding outer wall of movable block and combined block institute, and relative engagement is on concave face.

Wherein, this concave face is arranged on the corresponding outer wall of movable block and combined block institute, and raised face is arranged on combined block and the corresponding outer wall of movable block.

In view of the above, movable block can be that rotation is done in the axle center according to pivot, described raised face and concave face then are arranged at combined block and movable block respectively when articulating on the two corresponding outer wall of institute, to make movable block rotate an angle and combined block when fitting, but the proper relative engagement of raised face is on concave face, make the slit between this combined block and the movable block can't allow human organ stretch into, and then reach the anti-safe effect that crushes, compared to known technology " safety lock structure of Baby's umbrella carriage folding ", the utility model provides one to have more the articulation structure of safe handling effect, and then has more progressive.

The specific embodiment

The relevant a kind of perambulator bending joint of the utility model safety retaining clip device, [seeing also Fig. 1 and Fig. 2] includes joint set 1, concave face 2 and raised face 3 at least; Wherein:

Joint set 1, mainly by combined block 11, pivot end A 12, sidewall 13, axis hole 14, engagement groove 15, movable block 16, perforation 17, pivot 18, pivot end B 19 forms, combined block 11 1 end places are provided with pivot end A 12, also be formed with sidewall 13 on combined block 11 dual side-edges respectively, 13 of this two sidewalls all have axis hole 14 to run through, and between described two sidewalls 13 and be formed with engagement groove 15, establish a movable block 16 again, this movable block 16 is provided with a perforation 17, and movable block 16 can be for being placed in the engagement groove 15 and making axis hole 14 be communicated with into a through hole with perforation 17, then establish a pivot 18 and run through this axis hole 14 and perforation 17 simultaneously, and then movable block 16 can be rotated for the axle center according to pivot 18,16 1 end places also are provided with pivot end B 19 in movable block, then can be pivoted with the pole 4 of perambulator on pivot end A 12 and the pivot end B 19 respectively;

Concave face 2, [seeing also Fig. 3] can be arranged between combined block 11 2 sidewalls 13 and with 16 corresponding outer walls of movable block on;

Raised face 3 can be arranged on movable block 16 and 11 corresponding outer walls of combined block;

Thereby, when movable block 16 is articulated on the combined block 11, [seeing also Fig. 4] and movable block 16 rotations one angles are with combined block 11 during near applying, but raised face 3 proper relative engagement are on concave face 2, that is, [seeing also Fig. 5] this concave face 2 can be arranged on the outer wall of movable block 16, and raised face 3 can be arranged on combined block 11 outer walls between two sidewalls 13 again.

When using perambulator bending joint safety retaining clip device to implement, [seeing also Fig. 6] is incorporated on the perambulator by pole 4 when joint set 1 of the present utility model, [seeing also Fig. 3] this joint set 1 mainly can be carried out the pole 4 of perambulator the action of bending, when bending, [see also Fig. 4], is that rotation is done in the axle center via movable block 16 with pivot 18, pivot end B on the movable block 16 19 is rotated approximately to 180 °, and then make movable block 16 can with combined block 11 near fitting, through this, raised face 3 on these movable block 16 outer walls can correspond to the concave face 2 on combined block 11 outer walls, can effectively reduce slit between combined block 11 and the movable block 16 by this concave face 2 and raised face 3, and can further avoid human organ to stretch into and injured.

The utility model perambulator bending joint safety retaining clip device, its advantage is, [seeing also Fig. 3 and Fig. 6] is main by be provided with concave face 2 and raised face 3 in a joint set 1 that can be combined on the perambulator, and this concave face 2 is arranged on combined block 11 and 16 corresponding outer walls of movable block, 3 of this raised faces are arranged on movable block 16 and 11 corresponding outer walls of combined block, can effectively reduce the slit between combined block 11 and the movable block 16, [seeing also Fig. 4] and movable block 16 is rotated in the process of start, avoid the more tiny finger of infant to be strayed in the joint set 1 and damage, can reach good safe effect to make this joint set 1.

Only the above only is one of the utility model preferred embodiment, when can not with qualification the utility model scope.Promptly the equalization of being done according to the utility model claim generally changes and modifies, and all should still belong in the utility model patent covering scope.
