When the first rotating shaft 150 is fixed and the rotating member 110 rotates relative to the first rotating shaft 150, the limiting rod 200 is inserted into the second limiting groove 175 along with the rotation of the rotating member 110 to lock the rotating member 110 and the second rotating shaft 170, so as to limit the rotation between the second rotating shaft 170 and the rotating member 110, and ensure that when the hinge 400 is applied to the opening and closing door 500, the opening and closing door 500 is opened and then returns to the closed state, and the return is accurate.

Specifically, the first body 300 is configured to be fixedly connected to the first door 510, and the second body 310 is configured to be fixedly connected to the second door 520, so that the first door 510, the second door 520 and the hinge 400 form the opening/closing door 500. Referring to fig. 4, the first body 300 and the first rotating shaft 150, and the second body 310 and the second rotating shaft 170 can be fixed to each other by pre-tightening bolts, wherein the number of the pre-tightening bolts is not limited as long as the first body 300 and the first rotating shaft 150, and the second body 310 and the second rotating shaft 170 can be fixed stably. Gaskets can be further disposed between the contact surfaces of the first body 300 and the rotation member 110 and between the contact surfaces of the second body 310 and the rotation member 110, so as to reduce wear when relative rotation occurs between the first body 300 and the rotation member 110 and between the second body 310 and the rotation member 110.

Further, the inner surfaces of the first limiting groove 155 and the second limiting groove 175 can be provided with an elastic pad or an elastic adhesive layer, so that the first rotating shaft 150 and the second rotating shaft 170 rotate to the first limiting groove 155 and the second limiting groove 175, the limiting rod 200 can pop out the first limiting groove 155 or the second limiting groove 175, the limiting rod 200 is located in the accommodating groove 120 at a proper position, the limiting rod 200 is prevented from being completely located in the first limiting groove 155 or the second limiting groove 175, and the subsequent rotation of the first rotating shaft 150 or the second rotating shaft 170 is influenced.

As an improvement of the above scheme, referring to fig. 2 and 4, the rotating assembly 100 further includes a limiting block 250, the limiting block 250 is disposed in the accommodating groove 120, the limiting block 250 is provided with a limiting hole 260, the limiting rod 200 is inserted into the limiting hole 260, and the limiting block 250 can limit the position of the limiting rod 200 in the accommodating groove 120 and the movement direction of the limiting rod 200.

Specifically, the limiting block 250 can be fixed on the inner surface of the accommodating groove 120 by means of bolt pre-tightening, bonding or welding. Stopper 250 can keep gag lever post 200 in the position at the middle part of storage tank 120, and when gag lever post 200 moved along length direction, gag lever post 200 only took place the friction with the pore wall of spacing hole 260, compares in the cell wall emergence friction of gag lever post 200 with storage tank 120, and the frictional force that gag lever post 200 received is littleer, and hinge 400 is more smooth and easy when rotating. In addition, the wall of the limiting hole 260 limits the radial movement of the limiting rod 200, and limits the movement direction of the limiting rod 200 to be along the extending direction of the limiting hole 260, so as to ensure that the limiting rod 200 can enter or leave the first limiting groove 155 at a set position, or ensure that the limiting rod 200 can enter or leave the second limiting groove 175 at a set position.

Referring to fig. 4, when the limiting rod 200 is inserted into the limiting hole 260, a part of the bottom of the limiting rod 200 abuts against the hole wall of the limiting hole 260, when the limiting rod 200 moves along the length direction, the limiting rod 200 is exposed more on one side and less on the other side relative to the limiting block 250, the limiting rod 200 is exposed on more one side and tends to slide downward, and when the inclination tendency is too large, the limiting block 250 is not uniformly stressed and moves unstably, so that the limiting block 250 is disposed between the first rotating shaft 150 and the second rotating shaft 170, and can better keep limiting the limiting rod 200, but when the limiting block 250 is assembled, the alignment of the limiting block 250 is time-consuming.

Based on the above problem, further, referring to fig. 5, a positioning groove 115 is formed on an inner wall of the accommodating groove 120, and the limiting block 250 is inserted into the positioning groove 115. Through being provided with the constant head tank 115 and fixing a position to rotating the position that sets up of piece 110, can improve the efficiency of stopper 250 assembly on rotating piece 110, reduce stopper 250's the assembly degree of difficulty. Specifically, the inner wall of the receiving groove 120 includes a groove bottom and a side wall constituting the receiving groove 120, and the positioning groove 115 may be formed on the groove bottom or the side wall of the receiving groove alone, or may be formed on both the groove bottom and the side wall of the receiving groove 120.

As an improvement of another aspect of the above solution, referring to fig. 4, fig. 11 to fig. 13, the rotating assembly 100 further includes a first elastic member 230, a second elastic member 240, a first limiting post 210 and a second limiting post 220, wherein the first elastic member 230 and the second elastic member 240 are respectively sleeved on the outer surface of the limiting rod 200 and located at two ends of the limiting block 250, and a first end of the first elastic member 230 and a first end of the second elastic member 240 respectively abut against two ends of the limiting block 250; the first position-limiting post 210 and the second position-limiting post 220 are respectively fixedly connected to two ends of the position-limiting rod 200, and protrude out of the outer surface of the position-limiting rod 200 along the radial direction of the position-limiting rod 200, the first position-limiting post 210 abuts against the second end of the first elastic member 230, and the second position-limiting post 220 abuts against the second end of the second elastic member 240. The limiting block 250, the first elastic piece 230, the second elastic piece 240, the first limiting column 210 and the second limiting column 220 are matched to realize the resetting of the limiting rod 200 in the accommodating groove 120, so that the probability that the limiting rod 200 is always positioned in the first limiting groove 155 or the second limiting groove 175 to influence the rotation of the hinge 400 is reduced.

Specifically, referring to fig. 11, when the hinge 400 is in the closed state, the first elastic member 230 and the second elastic member 240 are not pressed, and the limit lever 200 is located at the center between the first rotating shaft 150 and the second rotating shaft 170. Referring to fig. 12 and 13, when the rotating member 110 rotates relative to the second rotating shaft 170, the limiting rod 200 is separated from the second limiting groove 175 along with the rotation and abuts against the outer surface of the second rotating shaft 170, and at this time, since the limiting rod 200 moves toward the first rotating shaft 150 and enters the first limiting groove 155, the second elastic member 240 is compressed by the limiting block 250 and the second limiting post 220. When the hinge 400 is subsequently returned to the closed state, the first limiting groove 155 is opposite to the second limiting groove 175, and the limiting rod 200 moves toward the second rotating shaft 170 under the action of the second elastic member 240, and stops moving after the second elastic member 240 releases the elastic force. It can be understood that, since the first elastic member 230 is disposed on the other side of the position-limiting rod 200, when the position-limiting rod 200 moves excessively in the direction toward the second rotating shaft 170, the first elastic member 230 is also compressed by the position-limiting block 250 and the first position-limiting column 210, the elastic force of the first elastic member 230 pulls back the position-limiting rod 200, and the position-limiting rod 200 finally returns to the initial position in the door-closed state shown in fig. 10.

Wherein, the first elastic member 230 and the second elastic member 240 may be selected as a spring, a bellows, or an elastic rubber. The first and second limiting columns 210 and 220 may be convex columns or annular abutting rings, and the first and second limiting columns 210 and 220 may be integrally formed with the first limiting rod 200 to form an integrated structure, or may be connected to the limiting rod 200 by welding or bonding.

Further, two ends of the limiting rod 200 are respectively provided with a through hole, and the first limiting column 210 and the second limiting column 220 are respectively arranged in the through holes in an interference fit manner. First spacing post 210 and fenestrate cooperation and second spacing post 220 can realize dismantling the joint with fenestrate cooperation to reduce the assembly degree of difficulty of first elastic component 230 and second elastic component 240 and gag lever post 200, and, conveniently dismantle first elastic component 230 and second elastic component 240 from gag lever post 200, after first elastic component 230 and second elastic component 240 lose elasticity because of structural fatigue, can continue to maintain the reset function of gag lever post 200 through changing, prolong the life of hinge 400.

On the other hand, the first limit column 210 and the second limit column 220 can be set as threaded columns, threaded holes which are arranged along the radial direction are formed in the limit rod 200, the threaded columns are connected with the threaded holes in a threaded mode to be detachable, and the threaded columns can be well adjusted to protrude in the radial direction of the limit rod 200 through matching with the threaded holes. Or, the first limiting column 210 and the second limiting column 220 can be configured as abutting rings, the abutting rings are provided with internal threads, the limiting rod 200 is provided with external threads, the abutting rings are detachably connected with the limiting rod 200 through threaded connection, and the distance between the abutting rings and the limiting block 250 can be well adjusted through the matching of the internal threads of the abutting rings and the external threads of the limiting rod 200, so that the first elastic piece 230 or the second elastic piece 240 can be ensured to be abutted, and the compressed amount of the first elastic piece 230 and the second elastic piece 240 can be adjusted. Or, the first limiting column 210 and the second limiting column 220 are provided with buckles, the limiting rod 200 is provided with a clamping groove, and the detachable connection is realized through the clamping.

In the using process of the hinge 400, since the receiving groove 120 is exposed to the outside, when the limiting block 250 is not fixed stably or the pre-tightening is weakened along with the use, the limiting block 250, the first elastic member 230 and the second elastic member 240 have a certain probability to be separated from the receiving groove 120 along with the movement of the first rotating shaft 150 or the second rotating shaft 170. And the first elastic member 230 and the second elastic member 240 are directly exposed to the outside and easily directly contact with the outside liquid or gas, so that the oxidation rate of the first elastic member 230 and the second elastic member 240 is accelerated, thereby affecting the elasticity of the first elastic member 230 and the second elastic member 240. In view of the above problem, the present embodiment further provides an improvement, the rotating assembly 100 further includes a cover plate 190, the cover plate 190 is fixed to the rotating member 110, and the cover plate 190 covers the accommodating groove 120.
