Abstract
The utility model relates to an automatic leaf-popping spring seat, comprising a cylinder, wherein the opening end of the cylinder is provided with an internal convex edge and a external convex edge; a hollow cavity formed among the internal convex edge, the external convex edge and the cylinder is internally provided with a boss; and a spring is abutted between one side of the boss and the bottom part of the cylinder, and the other side of the boss is provided with a contact block which penetrates through the internal convex edge and the external edge and is exposed out of the cylinder. The utility model has the advantages that the automatic leaf-popping spring seat is directly mounted on the original mounting hole of a door frame without modification to the door frame; the contact block totally stays in the cylinder to compress the spring when the door leaf stays in the closing state; the spring automatically pops the contact block out to push the door leaf open when the door leaf is opened instead of manually opening the door, and the operation is labor-saving and convenient; and the popped-out contact block is abutted against the door leaf to prevent the closing of the door under the action of vibration and wind force.
Description
Technical field
The utility model relates to a kind of spring base for automatic door leaf ejection.
Background technology
At present, existing door mostly needs people to open Door by Hand after unblanking, comparatively inconvenience.Especially when driving security door, because security door does not generally have door handle, and also heavier, only be door to be opened by the strength that is pulled outwardly key, comparatively require great effort.And existing door is very easily closed under external force effects such as wind-force, and especially security door does not have key to open, and usually brings unnecessary trouble to people.
The utility model content
The purpose of this utility model provides a kind of spring base for automatic door leaf ejection, and is simple in structure, easy to use, to overcome present prior art above shortcomings.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of spring base for automatic door leaf ejection, comprise cylinder, convex edge and outer convex edge in the mouth end of described cylinder is provided with, be provided with boss in the cavity that forms between interior convex edge, outer convex edge and the cylinder, between the bottom of side of boss and cylinder against spring, another side of boss is provided with contact block, and contact block passes outside interior convex edge and outer convex edge and exposed and the cylinder.
The beneficial effects of the utility model are: directly the utility model is installed on the doorframe on original installing hole, need not doorframe is transformed separately.When door leaf was in closure state, contact block was in compression spring in the cylinder fully; When door leaf was opened, spring ejected contact block automatically, and door leaf is pushed open, need not to open Door by Hand, and is laborsaving, convenient.And the contact block after ejecting is to be against on the door leaf, prevents that door is closed under the effect of vibration, wind-force.
Description of drawings
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the sectional view of the described a kind of spring base for automatic door leaf ejection of the utility model embodiment.
Among the figure:
1, cylinder; 2, interior convex edge; 3, outer convex edge; 4, boss; 5, spring; 6, contact block.
The specific embodiment
As shown in Figure 1, the described a kind of spring base for automatic door leaf ejection of the utility model embodiment, comprise cylinder 1, convex edge 2 and outer convex edge 3 in the mouth end of described cylinder 1 is provided with, be provided with boss 4 in the cavity that forms between interior convex edge 2, outer convex edge 3 and the cylinder 1, against spring 5, another side of boss 4 is provided with contact block 6 between the bottom of 4 one sides of boss and cylinder 1, and contact block 6 passes outside interior convex edge 2 and outer convex edge 3 and exposed and the cylinder 1.
During installation, cylinder 1 is placed in the installing hole on the doorframe, and is fixed on the doorframe by the outer convex edge of screw with cylinder 1.Boss 4 is stuck on the interior convex edge 2 of cylinder 1, plays position-limiting action.Door leaf is preferably done the processing of quenching in the corresponding position of contact block 6, strengthens abrasion resistance.
