Abstract

The invention provides a positioning rebounding rotating hinge for a door sill. A lug boss with a clamping groove is formed on the end face, facing a fixed seat, of a rotating shaft sleeve in an extension way, and is provided with a through hole penetrating through the rotating shaft sleeve, wherein a reamed hole is formed in the top of the through hole; a counter bored hole matched with the rotating shaft sleeve for rotation is formed in the fixed seat; the lug boss of the rotating shaft sleeve is inserted into the counter bored hole of the fixed seat; a clamping foot at one end of a torsion spring is fixed with the fixed seat; a dowel penetrates through the through hole and the counter bored hole; a cap is formed on the upper end face of the dowel; a resetting spring is sleeved on the dowel; a clamping structure is arranged on the lower end face of the dowel; the resetting spring and the section, with the cap, of the dowel are placed in the reamed hole; a buffer folded surface is symmetrically formed on the outer lateral surface of the rotating shaft sleeve; a cavity is formed in the position, on the same horizontal plane with the buffer folded surface, of the fixed seat; a buffer pressing part and a buffer spring are placed in the cavity; the buffer pressing part is pressed against the buffer folded surface of the rotating shaft sleeve under the action of the buffer spring. The positioning rebounding rotating hinge has an automatic resetting function, movement speed during resetting is decreased, and the service life of the door sill is prolonged.

Description

A kind of hurdle location resilience turning hinge

Technical field

The present invention relates to a technical field for hurdle assembly, refer in particular to a kind of hurdle location resilience turning hinge.

Background technology

The existing door hurdle being used in average family is generally used for restriction infant activity space and enters deathtrap to prevent infant, such as: kitchen, stair or bathroom etc.; Yet this door hurdle major part does not all have resilience reset function, if people come in and go out to open after guardrail, forget and close guardrail, it will be always in open mode, to losing of baby the effect stopping, the consequence causing is hardly imaginable; Although there is now a kind of door hurdle with automatic resilience function on market, but can there is because rebound velocity is too fast the situation that locking is inaccurate in the door hurdle of this structure in the process of automatic rebounding, and cause larger impact force when a grid and doorframe are collided, reduced widely the application life on door hurdle.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, provide a kind of durable, can automatically reset, lock accurately door hurdle location resilience turning hinge.

For achieving the above object, technical scheme provided by the present invention is: a kind of hurdle location resilience turning hinge, it includes holder, rotary axle box, pin, back-moving spring, buffering casting die, the buffer spring and the torsion spring that coordinate with buffering casting die, wherein, described rotary axle box has the boss with draw-in groove towards elongation moulding on the end face of holder, this boss has the through hole that runs through rotary axle box, the top of through hole forms reaming, on holder, have the counterbore rotating for coordinating with rotary axle box, the boss of described rotary axle box injects in the counterbore of holder, with the torsion spring clamping matching being placed in counterbore, and the card base of torsion spring one end and holder are fixed, described pin is through through hole and counterbore, its upper surface forms cap, and cover has back-moving spring, there is an interface arrangment lower surface, one section of back-moving spring and pin band block is placed in reaming, and the lateral surface symmetrical molding of rotary axle box has buffering folding face, on holder, in same level place, have cavity with this buffering folding face, buffering casting die and buffer spring are all placed in described cavity, and buffering casting die is inconsistent with the buffering folding face of rotary axle box under the effect of buffer spring.

Described interface arrangment is to form draw-in groove in the lower surface of pin, on this draw-in groove, is connected with jump ring.

The present invention is after having adopted such scheme, its great advantage is by torsion spring being installed between holder and rotary axle box, a hurdle is opened can be resetted afterwards automatically, and in the process resetting, buffer spring, the cooperation that cushions casting die and be molded over the buffering folding face of rotary axle box side, the translational speed having slowed down while resetting, makes a hurdle accurately prevent from colliding between a grid and doorframe when locking too quickly, has extended application life on door hurdle.

The specific embodiment

Below in conjunction with specific embodiment, the invention will be further described.

Referring to accompanying drawing 1 to accompanying drawing 5, show, door hurdle location resilience turning hinge described in the present embodiment, include holder 1, rotary axle box 2, pin 3, back-moving spring 4, buffering casting die 11, the buffer spring 12 and the torsion spring 13 that coordinate with buffering casting die 11, wherein, described rotary axle box 2 has the boss 6 with draw-in groove 5 towards elongation moulding on the end face of holder 1, the through hole 7 of this boss axle sleeve 2, the top of through hole 7 forms reaming 8, on holder 1, have the counterbore 9 rotating for coordinating with rotary axle box 2, the boss 6 of described rotary axle box 2 injects in the counterbore 9 of holder 1, with torsion spring 13 clamping matching that are placed in counterbore 9, the card base of torsion spring 13 one end and holder 1 are fixing, and the lateral surface symmetrical molding of rotary axle box 2 has buffering folding face 14, on holder 1, in same level place, have cavity 19 with this buffering folding face 14, buffering casting die 11 and buffer spring 12 are all placed in described cavity 19, and buffering casting die 11 is inconsistent with the buffering folding face 14 of rotary axle box 2 under the effect of buffer spring 12, described pin 3 is through through hole 7 and counterbore 9, its upper surface forms cap 10, and cover has back-moving spring 4, there is an interface arrangment lower surface, interface arrangment is to form draw-in groove 15 in the lower surface of pin 3, on this draw-in groove 15, be connected with jump ring 16, back-moving spring 4 is with one section of block to be placed in reaming 8 with pin 3.

When door hurdle opens the door, first stir the button on the first door lock 17, remove the locking of the first door lock 17, then door grid are up carried (remove the first door lock 17 is rear just can be carried), remove the locking of the second door lock 18, back-moving spring 4 plays a part to make a grid to reset, in addition, by torsion spring 13 being installed between holder 1 and rotary axle box 2, a hurdle is opened can be resetted afterwards automatically, and in the process resetting, buffer spring 12, buffering casting die 11 and the cooperation that is molded over the buffering folding face 14 of rotary axle box 2 sides, the translational speed having slowed down while resetting, when a hurdle is accurately locked, prevent from colliding between a hurdle and doorframe too quickly, extended the application life on door hurdle.

The examples of implementation of the above are only the present invention's preferred embodiment, not with this, limit practical range of the present invention, therefore the variation that all shapes according to the present invention, principle are done all should be encompassed in protection scope of the present invention.
