Abstract

The utility model is related to a kind of door body structure, especially a kind of small-sized grille door of self-closing of band buffering.The grille door includes a door leaf and the first door pillar and the second door pillar positioned at door leaf both sides, the door leaf by hinge and door closer be movably connected with on the first door pillar, second door pillar is equipped with electric control lock, door leaf is equipped with to be equipped with one or more and contacts the elastic buffering mechanism for reducing its closure impact force with door leaf with the matched auxiliary section of electric control lock, second door pillar.The small-sized grille door of self-closing of the utility model is when door leaf is closed; the excessive closing force that door closer generates carries out door leaf support elastic in advance when door leaf will be closed by elastic buffering mechanism; to offset excessive closing force; it avoids generating hard hit between door leaf and door pillar or doorframe, protects the stability of door leaf and doorframe structure, improves the durability used.

Description

The small-sized grille door of self-closing with buffering

Technical field

The utility model is related to a kind of door body structure, especially a kind of small-sized grille door of self-closing of band buffering.

Background technology

In present cell or garden etc., other than the gate of conventional all directions, passed in and out in order to facilitate resident family, Some wickets are offered in some corners toward contact, or in order to avoid frequently switching gate, are in addition being opened up by gate Wicket, such wicket are easily welded into the door body of cell structure, Convenient switch and disengaging often through tubing, at the same in order to It can be automatically closed after personnel's disengaging, often return and door closer is installed on such grille door.But door closer is most to be made With scene used at corridor fire resistant doorsets, in order to which for big, the solid feature of fire prevention thickness gate, the closing force of door closer is generally all It is larger, on the market without being closed so after existing grille door installation door closer using the closer on light-duty door leaf Power is excessive, and grille door can generate violent shock with doorframe or door side at closing time, and the material that such grille door often uses is all It is more frivolous, solder joint contact area is small, be easy to form desoldering after multiple impact, so the small-sized lattice of existing self-closing The useful life longevity of fence gate is not generally high, and usually the visible grille door that binding reinforcing is carried out with iron wire or adhesive tape, influences practicality Perception.

Utility model content

In order to solve the above-mentioned technical problem, the utility model, which provides one kind, can be effectively reduced small-sized grille door at closing time Impact force, improve door body useful life longevity band buffering the small-sized grille door of self-closing.

The grille door includes that a door leaf and the first door pillar and the second door pillar positioned at door leaf both sides, the door leaf pass through hinge Chain and door closer be movably connected with on the first door pillar, second door pillar be equipped with electric control lock, door leaf be equipped with it is automatically controlled Matched auxiliary section is locked, improvement is：Second door pillar be equipped with one or more contacted with door leaf reduce its close Close the elastic buffering mechanism of impact force.

Preferably, second door pillar is equipped with recessed with the matched vertical L-shaped of door leaf edge when door leaf is closed Into portion, L-shaped recess includes the vertical confined planes coordinated with door leaf front edge, and the elastically damping device is arranged in this and hangs down On straight confined planes.

Preferably, the elastic limit device includes the fixed column being fixed on vertical confined planes, is socketed outside fixed column There are a spring, one end of spring to be fixed in fixed column, a gasket is installed on the free end of spring.

Preferably, the gasket is flexible gasket.

For the small-sized grille door of self-closing of the utility model when door leaf is closed, the excessive closing force that door closer generates is in door Support elastic in advance is carried out when fan will close to door leaf by elastic buffering mechanism to keep away to offset excessive closing force Exempt to generate hard hit between door leaf and door pillar or doorframe, protects the stability of door leaf and doorframe structure, raising to use durable Property.

Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model embodiment；

Fig. 2 is the elastic buffering mechanism structural schematic diagram of the utility model embodiment.

Specific implementation mode

As Figure 1-Figure 2, the small-sized grille door of self-closing of the band buffering of the utility model including a door leaf 1 and is located at door The first door pillar 2 and the second door pillar 3 of both sides are fanned, the door leaf 1 is movably connected with and first by hinge 4 and door closer 5 On column 2, second door pillar 3 be equipped with electric control lock 6, door leaf 1 be equipped with 6 matched auxiliary section 7 of electric control lock, it is described Second door pillar is equipped with one or more and contacts the elastic buffering mechanism 8 for reducing its closure impact force with door leaf.

After door leaf is opened and personnel complete disengaging action, door leaf carries out shutdown action under the action of door closer 6, When door leaf will close, door leaf edge initially strikes elastic buffering mechanism 8, and elastic buffering mechanism 8 carries out bullet to door leaf 1 at this time Property support, slow down its shutdown action, while elastic buffering mechanism 8 is compressed, the reduction during gradually compressed gradually The door closing speed of door leaf realizes completely closing for door leaf until then by the adhesive action of auxiliary section 7 and electric control lock 6.

In order to complete shutdown action when the action of door leaf is limited, avoid completely by auxiliary section 7 and electric control lock 6 Impact force when bearing to be closed, in the present embodiment, second door pillar 3 be equipped with when door leaf is closed with door leaf edge matching The vertical L-shaped recess 9 closed, L-shaped recess 9 includes the vertical confined planes 29 coordinated with door leaf front edge, described Elastic buffering mechanism 8 is set on the vertical confined planes 10.

In the present embodiment, the elastic limit device 8 includes the fixed column 81 being fixed on vertical confined planes, fixed column It is socketed with a spring 82 outside 81, one end of spring 82 is fixed in fixed column 81, and a gasket is equipped on the free end of spring 82 83。

In order to avoid generating larger noise at the time of contact, in the present embodiment, the gasket is flexible gasket, such as rubber Rubber cushion, silicagel pad etc.；In addition, the fixed column 81 is a screw rod.

The above is only the preferred embodiment of the present invention, and it does not limit the scope of the patent of the present invention, Equivalent structure or equivalent flow shift made by using the description of the utility model and the drawings, is directly or indirectly transported Used in other related technical areas, it is equally included in the patent within the scope of the utility model.
