Abstract

The utility model discloses an automatic restoring safe door fence, which comprises a door frame, a door fence is hinged in the door frame, a connecting seat is firmly mounted on the right lower end of the door fence, an upper support lug and a lower support lug are extended from the front end of the connecting seat, the left and the right sides of a bottom tube of the door frame are respectively provided with a left press plate and a right press plate, an upper cavity and a lower cavity which are clamped between the upper support lug and the lower support lug are extended from the tops of the left press plate and the right press plate, a central shaft which passes through the upper and the lower support lugs and the upper and the lower cavities is inserted in the bottom tube of the door frame, a torsional spring is sleeved on the central shaft, and both ends of the torsional spring respectively abuts against the upper and the lower cavities. Because of the structure, the door fence can be opened inward or outward, moreover, after being opened, the door fence does not need to be manually closed but is automatically closed under the function of the torsional spring, consequently, the safety performance of the safe door fence is better, the safety of infants can be more sufficiently protected, and the safe door fence is simple and safe to operate.

Description

A kind of safety door sill that automatically resets

Technical field

The utility model belongs to a kind of safety door sill, relates in particular to a kind ofly need not realize the safety door sill of closing the door automatically by any external force.

Background technology

At present, in order to prevent the specific place of the careless turnover of child, the action of closing the door of traditional baby's safety door sill is the safety door sill of finishing and having certain altitude with hand.

Safety door sill on the market generally comprises doorframe and door hurdle two parts now, and the door hurdle is to be fixed on the doorframe by door-hinge, can rotate around axle, and establish locking device, thereby realize opening the door and closing the door function.But general door hurdle all can not be under the self gravitation effect, realize closing the door automatically function, thereby the user in practical operation, often occurs and forget and close the door or carry the situation that large piece article is inconvenient to close the door, make the setting of safety door sill perform practically no function, the effect of its product also can't realize, have very big potential safety hazard.

Summary of the invention

In order to overcome the deficiencies in the prior art, it is a kind of easy to operate that the utility model provides, and do not need to realize the safety door sill of closing the door automatically by any external force effect after unlatching.

The technical scheme that its technical problem that solves the utility model adopts is:

A kind of safety door sill that automatically resets, it comprises doorframe, be hinged with a hurdle in the doorframe, the lower end, right side on described door hurdle is installed with Connection Block, the Connection Block front end is extended with upper and lower journal stirrup, the and arranged on left and right sides of described doorframe bottom tube is respectively arranged with left and right compressing tablet, the top of left and right compressing tablet is extended with the upper and lower cavity that is installed between the upper and lower journal stirrup, be fitted with the axis that passes upper and lower journal stirrup and upper and lower cavity on the described doorframe bottom tube, be set with torsion spring on the described axis, the two ends pin difference roof pressure of torsion spring is on upper and lower cavity;

As improvement of the technical scheme, described axis is fixedly mounted on the upper journal by screw thread;

As further improvement in the technical proposal, described Connection Block is provided with the nut hole that is used to install the location nut.

The beneficial effects of the utility model are: this structure make the door hurdle can be in the past in or open outward; and after opening a hurdle; need not manually close the door; the door hurdle just can carry out closing motion voluntarily under the torsion spring effect; make that the security performance of safety door sill is better; can more adequately protect baby's safety, it is easy to operate and safe.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is a scheme of installation of the present utility model;

Fig. 2 is the A place enlarged drawing of Fig. 1;

Fig. 3 is the structure broken away view that left compressing tablet is removed at the A place of Fig. 1;

Fig. 4 is a left compressing tablet structural representation of the present utility model.

The specific embodiment

With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of safety door sill that automatically resets, it comprises doorframe 1, be hinged with a hurdle 2 in the doorframe 1, the lower end, right side on described door hurdle 2 is installed with Connection Block 3, described Connection Block 3 is provided with the nut hole 32 that is used to install the location nut, the location nut can adopt two, thereby effectively Connection Block 3 is fixedly mounted on the bottom bar 21 on a hurdle 2, Connection Block 3 front ends are extended with, down journal 31,31 ', the left side of described doorframe 1 bottom tube 11, right both sides are respectively arranged with a left side, right compressing tablet 41,41 ', a left side, right compressing tablet 41,41 ' top is extended with and is installed in, down journal 31, on between 31 ', lower chamber 42,42 ', be fitted with on described doorframe 1 bottom tube 11 and pass, down journal 31,31 ' and on, lower chamber 42,42 ' axis 5, be set with torsion spring 6 on the described axis 5, the two ends pin difference roof pressure of torsion spring 6 is last, lower chamber 42, on 42 '.This product is installed for convenience, and described axis 5 is fixedly mounted on the upper journal 31 by screw thread.

When this product uses, at first with door hurdle 2 when hinged axis 5 is opened toward in, a door hurdle 2 drives right compressing tablet 41 ' past interior rotation simultaneously, thereby make torsion spring 6 twist, when unclamping hurdle 2, door hurdle 2 automatically reverts to door hurdle 2 state of closing the door under the active force of torsion spring 6; When hinged axis 5 was opened outward, a door hurdle 2 drove left compressing tablet 41 simultaneously and rotates outward, thereby makes torsion spring 6 twist as door hurdle 2, and when unclamping hurdle 2, a hurdle 2 is returned to the state of closing the door under the active force of torsion spring 6.

This structure make door hurdle 2 can be in the past in or open outward, and after opening a hurdle, need not manually close the door; the door hurdle just can carry out closing motion voluntarily under the torsion spring effect; make that the security performance of safety door sill is better, the baby's that can more adequately protect safety, it is easy to operate and safe.
