Preferably, the dog is provided with two sets ofly, and two sets of dogs are mirror symmetry about the spliced pole, and the internal face of dog is the arc surface, and is equipped with three universal ball on the arc surface, and three universal ball is the equidistant distribution of annular, seted up on the spliced pole lateral wall with universal ball matched with spout, universal ball and spout roll fit.

Preferably, two damping holes are formed in the plunger in a penetrating mode, a groove is formed in the right end face of the plunger, a first magnet is fixedly arranged in the groove, and a fixing frame is arranged on the right side of the plunger.

Preferably, the fixed frame is transversely fixed on the side wall of the shell through a screw and is internally provided with a rectangular mounting groove, a second magnet is fixedly arranged in the rectangular mounting groove, and the first magnet and the second magnet are magnets with the same name.

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

1. the three universal balls are used as the supports of the connecting columns, so that the contact area is small, the frictional resistance is small, the connecting columns can move smoothly when the door is opened, and the force for opening the door can be reduced to a certain extent.

2. The utility model discloses novel structure, reasonable in design, easy operation, because the repulsion that produces between the first magnetite of same name and the second magnetite, and under the state of closing the door, the distance between first magnetite and the second magnetite is shortest to the repulsion is the biggest, and the resistance grow gradually, thereby makes the speed of closing the door more gently stable.

Fig. 1 is a front view of the structure of the present invention;

fig. 2 is a schematic sectional view taken along line a-a in fig. 1.

In the figure: the universal ball comprises a shell 1, a supporting plate 2, a connecting column 3, a sliding groove 301, a return spring 4, a stop block 5, a support rod 6, a plunger 7, a damping hole 701, a first magnet 8, a second magnet 9, a fixing frame 10 and a universal ball 11.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 2, the present invention provides a technical solution: the utility model provides a dynamics of opening the door is lighter and close more steady damping composite spring of door speed, includes

casing

1, and 1 inside cavity of casing sets up, installs layer board 2, spliced pole 3, reset spring 4, dog 5, branch 6 and plunger 7 from the left hand right side in proper order in the casing 1, and the tip of layer board 2 is inconsistent with the counterbalance of gyro wheel, and in practical, the door-hinge drives the turbine and rotates to make layer board 2 drive 3 linear motion of spliced pole. The device is an improvement on the existing floor spring, so the specific structure of the floor spring is not described here. 3 one end of spliced pole and 2 fixed connection of layer board, 3 other ends of spliced pole run through reset spring 4 and branch 6 fixed connection, and the one end fixed connection plunger 7 of spliced pole 3 is kept away from to branch 6, and dog 5 is fixed to be set up on the lateral wall of casing 1 and inconsistent with reset spring 4's right-hand member, and the internal face of dog 5 is provided with the universal ball of a plurality of.

As shown in fig. 1 and 2, two sets of stoppers 5 are provided, and the stoppers 5 serve to limit the right end of the return spring 4. Two sets of dog 5 are mirror symmetry about spliced pole 3, and the internal face of dog 5 is the arc surface, and is equipped with three universal ball 11 on the arc surface, and three universal ball 11 is the equidistant distribution of annular, has seted up on the 3 lateral walls of spliced pole with universal ball 11 matched with spout 301, universal ball 11 and spout 301 roll fit. Adopt three universal ball 11 as the support of spliced pole 3, area of contact is little, and frictional resistance is little to when can making opening the door, the spliced pole 3 removes more in the same direction as smooth, thereby can alleviate the dynamics of opening the door to a certain extent.

As shown in fig. 1, two damping holes 701 are formed in the plunger 7 in a penetrating manner, a groove is formed in the right end face of the plunger 7, a first magnet 8 is fixedly arranged in the groove, a fixing frame 10 is arranged on the right side of the plunger 7, the fixing frame 10 is transversely fixed on the side wall of the shell 1 through screws, a rectangular mounting groove is formed in the fixing frame, a second magnet 9 is fixedly arranged in the rectangular mounting groove, and the first magnet 8 and the second magnet 9 are magnets of the same name. In the door-open state, the distance between the first magnet 8 and the second magnet 9 is longest, so that the repulsive force is smallest; in the closed state, the distance between the first magnet 8 and the second magnet 9 is shortest, so that the repulsive force is greatest, and therefore, in the closed state, the resistance gradually becomes larger, so that the closing speed is more gentle and stable.

The working principle is as follows: in the actual use process, when the door is opened, the door shaft drives the turbine to deflect clockwise, so that the connecting column 3 drives the plunger 7 to move towards the left side, the distance between the first magnet 8 and the second magnet 9 is gradually increased, the repulsion force is smaller and smaller, the three universal balls 11 are adopted as the supports of the connecting column 3, the contact area is small, the friction resistance is small, the connecting column 3 can move more smoothly when the door is opened, and the door opening force is lighter; when closing the door, the door-hinge drives the turbine anticlockwise and deflects for spliced pole 3 drives plunger 7 and removes to the right side, makes the distance between first magnetite 8 and the second magnetite 9 shorten gradually, thereby repulsion grow more greatly more, makes the resistance also grow gradually, thereby makes the speed of closing the door more gently stable.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
