Abstract
The invention relates to a spring seat automatically ejecting a leaf. The spring seat comprises a cylinder, wherein the cylinder is a hollow cylinder; an inwards convex edge and an outwards convex edge are formed at the upper end of the cylinder; a spring, a contact block and a boss are sequentially arranged in the cylinder from bottom to top; the spring is provided with the contact block; the contact block is provided with the boss; and the boss is clamped on the inwards convex edge of the cylinder. The spring seat has the beneficial effects that: when a door leaf is in a closed state, the contact block is completely positioned in the cylinder to compress the spring; and when the door leaf is opened, the spring automatically ejects the contact block to push the door leaf without opening a door manually, thereby saving labor and being convenient. Furthermore, the ejected contact block leans against the door leaf to prevent the door from being closed under the action of vibration and wind power.
Description
Technical field
The present invention 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.
Summary of the invention
The purpose of this invention is to provide a kind of spring base for automatic door leaf ejection, overcome the above-mentioned deficiency that prior art exists.
The objective of the invention is to realize through following technical scheme:
A kind of spring base for automatic door leaf ejection comprises cylinder, and said cylinder is a hollow cylinder; Convex edge and outer convex edge in the cylinder upper end forms are provided with spring, contact block and boss from the bottom up successively in the cylinder, spring is provided with contact block; Contact block is provided with boss, and said boss is stuck on the interior convex edge of cylinder.
Beneficial effect of the present invention is: 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 in the effect of vibration, wind-force closure down.
Description of drawings
According to accompanying drawing the present invention is done further explain below.
Fig. 1 is the structural representation of the described spring base for automatic door leaf ejection of the embodiment of the invention;
Fig. 2 is the assembling drawing of the described spring base for automatic door leaf ejection of the embodiment of the invention.
Among the figure:
1, cylinder; 2, interior convex edge; 3, spring; 4, boss; 5, contact block; 6, outer convex edge.
The specific embodiment
Shown in Fig. 1-2, the described a kind of spring base for automatic door leaf ejection of the embodiment of the invention comprises cylinder 1; Said cylinder 1 is a hollow cylinder, and convex edge 2 and outer convex edge 6 in cylinder 1 upper end forms are provided with spring 3, contact block 5 and boss 4 from the bottom up successively in the cylinder 1; Spring 3 is provided with contact block 5; Contact block 5 is provided with boss 4, and said boss 4 is stuck on the interior convex edge 2 of cylinder 1, plays position-limiting action.Door leaf is done the processing of quenching at last in the corresponding position of contact block 5, strengthens abrasion resistance.
