Detailed Description

The invention will be further described with reference to the following specific embodiments:

example 1:

as shown in fig. 1 to 9, a stable motorcycle hook 2 of the present invention comprises a base 1, a hook 2 and a locking member 3, wherein a protrusion is formed on the base 1, the hook 2 and the locking member 3 are connected and fixed to the base 1 in a manner of being hinged to the protrusion, the protrusion is formed into a first protrusion 11 and a second protrusion 12, the first protrusion 11 is spaced from the second protrusion 12, the lower end of the hook 2 is clamped between the first protrusion 11 and the second protrusion 12, a first through hole 31, a second through hole 111, a third through hole 21 and a fourth through hole 121 are sequentially formed between the locking member 3, the first protrusion 11, the hook 2 and the second protrusion 12, the hook 2 and the locking member 3 are connected and fixed to the base 1 by inserting a pin 4 into the first through hole 31, the second through hole 111, the third through hole 21 and the fourth through hole 121, the pin 4 and the hook 2 are relatively fixed to the hook 2 and can rotate synchronously, the first lug 11 and the second lug 12 share the gravity on the hook 2 at the same time, so that the connection between the hook 2 and the base 1 is firmer and is not easy to be damaged; the articulated department of the 3 lower extremes of locking member is provided with torsional spring 5, 5 suits of torsional spring are in on the pivot 4, the one end of torsional spring 5 is fixed on the locking member 3, and the other end is fixed on the pivot 4, when rotating during the locking member 3 under the effect of torsional spring 5, locking member 3 can the automatic recovery original position.

Example 2:

the difference from example 1 is that: as shown in fig. 9, the shaft post 41 of the shaft pin 4 is shaped like a D, the shaft pin 4 of the D has a flat surface 41a and an arc surface 41b, the side surface of the lower end of the hook 2 is shaped with a locking screw hole 22, a locking bolt 6 is screwed in the locking screw hole 22, the locking bolt 6 abuts against the flat surface 41a of the D of the shaft post 41, and the locking bolt 6 is fixed on the flat surface 41a to position more accurately, and on the other hand, the hook 2 and the shaft pin 4 can be fixed more firmly.

Example 3:

the difference from example 1 is that: as shown in fig. 8, a round hole 32 is formed on the outer side surface of the lower end of the locking element 3, the torsion spring 5 is placed in the round hole 32, one end of the torsion spring 5 is fixed in the round hole 32, a shaft cap 42 is formed on the shaft pin 4, and the other end of the torsion spring 5 is fixed on the lower surface of the shaft cap 42.

Example 4:

the difference from example 1 is that: the medial surface of first lug 11 and second lug 12 the shaping respectively has first shrinkage pool 112 and second shrinkage pool 122 that is in the same position, couple 2 the lower extreme with the articulated department both sides face of base 1 the shaping respectively have with the corresponding recess 23 of first shrinkage pool 112 and second shrinkage pool 122 the centre gripping has ball and spring between recess 23 and first shrinkage pool 112 and the second shrinkage pool 122, recess 23 and shrinkage pool with second through-hole 111, third through-hole 21 and fourth through-hole 121 set up for the eccentric circle, recess 23 sets up to more than two.

More than two grooves 23 are arranged along the rotating track of the first concave hole 112 and the second concave hole 122 around the shaft pin 4, and the grooves 23 can play a role in positioning the hook 2.

The recess 23 that the both sides face that couple 2 lower extreme set up with first shrinkage pool 112 and the second shrinkage pool 122 of first lug 11 and second lug 12 are at the cooperation of spring and ball, can make couple 2 under the condition of recess 23 location, light more, simply rotate between first lug 11 and the second lug 12 couple 2.

Before the hook 2 rotates, the balls of the first concave hole 112 and the second concave hole 122 are propped in the groove 23 under the action of the spring; when the hook 2 rotates, the hook 2 presses the balls to the spring, namely the balls are pressed into the first concave hole 112 and the second concave hole 122, and the balls are separated from the groove 23; when the ball reaches the next groove 23, the ball is supported in the groove 23 again under the action of the spring, and the positioning and limiting effects are achieved.

The arrangement of the balls and the springs on the two side faces is more stable and labor-saving relative to the balls and the springs on the single side face, friction between the hook 2 and the first lug 11 and the second lug 12 can be reduced, and the hook has better flexibility.

Example 5:

the difference from example 1 is that: as shown in fig. 10 and 11, a first circular arc 12a and a second circular arc 12b are respectively formed on the front side and the rear side above the second protrusion 12, a notch 24 matched with the second protrusion 12 is formed at the lower end of the hook 2, a right-angle side 24a matched with the first circular arc 12a is formed on the front side of the notch 24, and an extended arc side 24b matched with the second circular arc 12b is formed on the rear side of the notch 24.

When the hook 2 rotates forwards, the front side right-angle edge 24a of the notch 24 is clamped on the front side surface of the second bump 12 after being separated from the first arc 12a, so that the hook 2 is limited by the front side;

when the hook 2 rotates backwards, the rear side extended arc edge 24b of the notch 24 is clamped on the rear side surface of the second bump 12 after being separated from the second arc 12b, so that the hook 2 is limited by the rear side.
