Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description.
Examples
As shown in fig. 1, the embodiment is an improved three-bar cantilever structure, which includes a joint head 1, a long bar 2, a ram 3 and a vertical bar 4, wherein the long bar 2, the ram 3 and the vertical bar 4 are made of elastic glass fiber reinforced plastic.
An exploded view of this example is shown in figures 3 and 4, in which only one hinge pin 12 is used.
The joint head 1 is fixedly connected with the connecting end of the long rod 2. The joint head 1 has a structure as shown in fig. 6 and 7, and is provided with a long rod limiting groove 11, and a pair of long rod hinge pin mounting holes 13 are provided at corresponding positions on two groove side walls of the long rod limiting groove 11. A boss is designed at the bottom of the long rod limiting groove 11, and one plane of the boss is a joint head side limiting surface 14.
As shown in fig. 8, a ram hinge pin mounting hole 31 is formed through a connecting end of the ram 3, and the ram hinge pin mounting hole 31 is a long circular hole, and the length direction of the ram hinge pin mounting hole 31 is parallel to the axial direction of the ram 3. In fig. 8, the position of the ram hinge pin installation hole 31 on the connection end of the ram 3 is slightly lower, and the position on the connection end of the ram 3 that is slightly higher than the rear is provided with the locking protrusion 32 that protrudes forward, and since the connection end of the ram 3 is flat, the number of the locking protrusions 32 is two, and the two locking protrusions are symmetrically arranged on both sides of the connection end of the ram 3. The free end of the locking lug 32 is provided with a rounded chamfer. A ram side limiting surface 33 is arranged above the front end of the connecting end of the ram 3, and the extending direction of the ram side limiting surface 33 is parallel to the length direction of the long round hole of the ram hinge pin shaft mounting hole 31. The lower side of the front end of the connecting end of the rod 3 is provided with an arc chamfer.
Referring to fig. 9 and 10, the connecting end of the vertical rod 4 is provided with a pair of vertical rod hinge pin mounting seats 41, and the two vertical rod hinge pin mounting seats 41 are provided with a pair of vertical rod hinge pin mounting holes 42. The concave part between the two upright rod hinge pin shaft mounting seats 41 forms an upright rod limiting groove 43, and the side wall of the upright rod limiting groove 43 is symmetrically provided with concave locking grooves 44. The locking groove 44 corresponds to the locking lug 32 in shape, size and position, and can form an adaptive inserting structure, and meanwhile, the inserting depth of the locking lug 32 is slightly smaller than the length of the long round hole of the ram hinge pin shaft mounting hole 31.
The long rod hinge pin mounting hole 13, the vertical rod hinge pin mounting hole 42 and the ram hinge pin mounting hole 31 are hinged by the hinge pin 12 to form the improved three-rod outward-projecting structure of the embodiment. In the structure, the clockwise rotation direction of the upright 4 is limited by the bottom of the long rod limiting groove 11, and the clockwise rotation direction of the ram 3 is limited by the bottom of the upright limiting groove 43.
Referring to fig. 5, the open axial cross-sectional view of the present structure shows that the lever-side stopper surface 33 and the joint-side stopper surface 14 are closely attached to each other, thereby achieving a stopper effect. The length of the ram-side limiting surface 33 and the length of the oblong hole of the ram hinge pin mounting hole 31 are both L. Therefore, when the ram 3 is pulled outward by the distance L, the engagement between the ram-side stopper surface 33 and the joint-side stopper surface 14 is lost, the ram 3 can be freely rotated counterclockwise, and the vertical rod 4 can be freely rotated counterclockwise. In fig. 5 it can also be seen that the joint head 1 is provided with a tether hole 15.
The improved three-bar cantilever structure of the embodiment is shown in an opening state in fig. 1. When the folding is needed, the ram 3 is pulled outwards, the insertion locking relationship between the locking groove 44 and the locking projection 32 and the rotation limiting relationship between the ram side limiting surface 33 and the joint side limiting surface 14 are released, and then the ram 3 and the upright rod 4 are rotated through the hinge shaft to form the folding state shown in fig. 2.
