Abstract

The present invention relates to a kind of bearing pin of crank limited block, the bearing pin is mainly linked together about the two pieces crank agreed with limited block baffle plates by its axle, two pieces of crank limited block baffle plates are allow to be rotated around the shaft centre line of the bearing pin, so as to which shape is at a certain angle between the side rib of the baffle plate, the angle can freely be set according to the design needs, so as to play certain versatility.

Description

A kind of bearing pin of crank limited block

Technical field

The present invention relates to a kind of bearing pin of crank limited block, the bearing pin is mainly by its axle by about the two pieces cranks agreed with Limited block baffle plate links together, and two pieces of crank limited block baffle plates is rotated around the shaft centre line of the bearing pin, so that Shape is at a certain angle between the side rib of the baffle plate, and the angle can freely be set according to the design needs, so as to play one Fixed versatility.

Background technology

Identical components are not retrieved.

The content of the invention

Fig. 1 is the elevation of the bearing pin of the crank limited block, and the form of the bearing pin is upper and lower two-section different-diameter and debugging Cylinder, but share a center line.

Fig. 2 is the elevation view of the bearing pin of the crank limited block.

Fig. 3 is the top view of the bearing pin of the crank limited block.

A diameter of 3 millimeters of the small one end of the diameter of the bearing pin, are highly 3.6 millimeters.

A diameter of 4 millimeters of the big one end of the diameter of the bearing pin, are highly 0.2 millimeter.

The size of the bearing pin can be according to being actually needed and each parts zoom in and out in proportion.

The main member of the bearing pin should have enough mechanical strengths, to keep out the rotation of crank.

Coordinated between the small one end of the diameter of the bearing pin and the hole of baffle plate using gap, so that baffle plate can be around the bearing pin Freely rotate.

Brief description of the drawings

Fig. 1 is the elevation of the bearing pin of the crank limited block, and the form of the bearing pin is upper and lower two-section different-diameter and debugging Cylinder post, but share a center line.

Fig. 2 is the elevation view of the bearing pin of the crank limited block.

Fig. 3 is the top view of the bearing pin of the crank limited block.

Embodiment

The present invention relates to a kind of crank limited block, and it is mainly used in the crank of limiting child seat slider-crank mechanism Rotational angle, so that crank rotates in the angular range of design code, to reach corresponding design requirement, Fig. 1 is the song Handle limits the partition figure of block block, and 1 in Fig. 1 is covered on limited block bearing pin, and 2 be limited block baffle plate, and 3 be limited block bearing pin, and 4 be to paste Double faced adhesive tape, Fig. 2 are constitutional diagrams, and Fig. 3 is two extreme positions of the crank limited block, i.e., it can limit crank in 90 degree of plane Rotated between to 270 degree.

Fig. 1 is that the elevation of the crank limited block takes figure apart.

1 in Fig. 1 is covered on limited block bearing pin, is mainly used in limited block bearing pin together by two pieces of limited block baffle combinations Together.

2 in Fig. 1 be limited block baffle plate, and it can be used for blocking in ad-hoc location with two parallel facades of horizontal plane Crank.

3 in Fig. 1 be limited block bearing pin.

4 in Fig. 1 be sticking two-faced adhesive tape, and it is mainly used in the crank limited block being pasted onto in specific plane.

Fig. 2 is the constitutional diagram that each parts are combined, and its major limitation crank turns at positive 46 degree between -90 degree It is dynamic.

Fig. 3 is the extreme position figure of the crank limited block, i.e., maximum can limit crank in 270 degree of plane, and minimum can be with Limitation crank rotates between 90 degree of plane.

The size of the limited block can be according to being actually needed and each parts zoom in and out in proportion.

The main member of the limited block should have enough mechanical strengths, to keep out the rotation of crank.

Claims

1. the present invention relates to a kind of bearing pin of crank limited block, the bearing pin is mainly limited about the two pieces cranks agreed with by its axle Position block baffle plate links together, and two pieces of crank limited block baffle plates is rotated around the shaft centre line of the bearing pin, so as at this Shape is at a certain angle between the side rib of baffle plate, and the angle can freely be set according to the design needs, certain so as to play Versatility.

2. be based on claim 1, a diameter of 3 millimeters of the small one end of the diameter of the bearing pin, be highly 3.6 millimeters.

3. a diameter of 4 millimeters of the big one end of the diameter based on claim 1 bearing pin, be highly 0.2 millimeter.

4. the size based on claim 1 bearing pin can be according to being actually needed and each parts zoom in and out in proportion.

5. the main member based on claim 1 bearing pin should have enough mechanical strengths, to keep out the rotation of crank.

6. coordinated between the small one end of the diameter based on claim 1 bearing pin and the hole of baffle plate using gap, so that gear Plate can freely rotate around the bearing pin.
