As a further aspect of the present invention: the connecting mechanism comprises a coaxial spring, the coaxial spring is arranged on the inner side of the first connecting pipe, a first twisting part and a second twisting part are respectively arranged on the front side and the rear side of the coaxial spring, the second twisting part is connected with the second connecting pipe through a single-head rivet, the first twisting part is connected with the first connecting pipe through a wave spring, a plurality of grooves are formed in the first twisting part, and wear-resistant sealing rings movably connected with the second connecting pipe are arranged on the inner sides of the grooves.

As a further aspect of the present invention: the number of the wear-resistant sealing rings is not less than two.

As a further aspect of the present invention: the pipe diameter of the first connecting pipe is equal to that of the second connecting pipe.

As a further aspect of the present invention: and hinge covers are arranged on one sides, away from the first connecting pipe, of the second connecting pipes and are clamped with the second connecting pipes.

Compared with the prior art, the beneficial effects of the utility model are that:

1. through the arrangement of the connecting mechanism, when the hinge is closed, the wear-resistant sealing ring arranged on the first twisting piece rubs with the pipe wall of the second connecting pipe on the left leaf of the hinge, and effective friction force is generated to play a role in buffering and decelerating, so that the closing speed of the door is slowed down, and the safety is improved;

2. through setting up the hinge lid, can avoid each part of coupling mechanism to take place to run the position, do benefit to hoisting device's stability.

Drawings

Fig. 1 is a schematic structural view of a spring buffer hinge.

In the figure: 1-hinge left leaf, 2-hinge right leaf, 3-first torsion piece, 4-second torsion piece, 5-wave spring, 6-single-head rivet, 7-hinge cover, 8-coaxial spring and 9-wear-resistant sealing ring.

Detailed Description

The technical solution of the present patent will be described in further detail with reference to the following embodiments.

Reference will now be made in detail to embodiments of the present patent, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present patent and are not to be construed as limiting the present patent.

Example 1

Referring to fig. 1, in an embodiment of the present invention, a spring buffering hinge includes a hinge left sheet 1 and a hinge right sheet 2, a first connecting pipe is provided on the left side of the hinge right sheet 2, a second connecting pipe corresponding to the first connecting pipe is provided on the front and back sides of the right end of the hinge left sheet 1, and the first connecting pipe and the inner side of the second connecting pipe are provided with a connecting mechanism having a buffering function.

Example 2

In this embodiment, coupling mechanism includes coaxial spring 8, coaxial spring 8 sets up at first connecting pipe inboardly, coaxial spring 8 front and back both sides are provided with first torsion piece 3 and second torsion piece 4 respectively, second torsion piece 4 is connected with the second connecting pipe through single-end rivet 6, first torsion piece 3 is connected with first connecting pipe through wave spring 5, be provided with a plurality of recesses on the first torsion piece 3, the recess inboard is provided with the wear-resisting sealing washer 9 with second connecting pipe swing joint, and through setting up coupling mechanism, when making the hinge close, the wear-resisting sealing washer 9 that sets up on the first torsion piece 3 rubs with the second connecting pipe wall on the left leaf 1 of hinge, produces effective frictional force and plays buffering deceleration effect to slow down the closed speed of door, improve the security.
